Description

Ski boot and method of manufacturing a ski boot The invention relates to a ski boot and a method for producing a ski boot, wherein the ski boot is essentially composed of two parts, which after their completion be joined together.

It is already known to manufacture shoes in such a way that the upper fttr is made and that a sole is subsequently sewn into this upper part, is welded or the like.

Here it is necessary to have the upper part made of flat material as usual E.g. made of leather or fabric and for the purpose of attaching the sole either to sew on a frame or to zwisken the upper part of the shoe to a double sole, after which the actual sole is molded. This manufacturing method harbors essentials Disadvantages in themselves, as in the manufacture of ski boots as a result of the required thick upper leather and the required thick sole the individual fastening and Assembly work can only be carried out with great difficulty.

It is also known to manufacture ski boots in such a way that the individual Parts are made from plastic injection molding or from a molded rubber part. In this case, however, it is necessary to provide joints, as well as the slip-in opening to cover with cuffs or the like, as it is difficult at all to to adapt such a shoe to the respective inner foot shape. Z / ar are already on this Steps have been taken to include, for example, an inflatable liner or a Screw-in pressure plate or a tensionable inner shoe will go ahead.

This enabled these designs both in terms of manufacture of the shoe as well as in the formation of the insertion slot, furthermore the formation the size adjustment not yet satisfactory (French Patent specification 1 495 903, 1 472 864, 1391 829, Swiss patent specification 433 055, GNS 1 904 449). In these known ski boot designs, it has also already been proposed have been designed to provide a central tension, as well as side or rear slip-in openings as well as to provide a backwards foldable shoe part in order to get into one at all to be able to slip on such a shoe. When it is very cold, the one used here Plastic, however, is relatively stiff and the individual pressing devices have Insofar as the contact tension either in the case of using a Bellows the same size in all places and in the case of using a stiff one Pressure plate can be locally excessive while using a tensionable inner shoe (French Patent Publication 1 391 829) because of the large number of implementations and is too expensive because of the complicated mechanics as well as in the long run in practice it is not brannhbir because of rapid wear and tear when walking. Farther it is previously known that the sole of a ski boot can be designed or constructed in several parts.

to provide strongly padded edges and furthermore insoles in the shoe injection area to arrange, as it is also possible, stiffening aia sheets e.g. for one made of plastic or rubber existing ski boots (GMS 1 881 919, 1 743 952, 1 971 427, DAS 1 145 057). Furthermore, it is previously known to have a ski boot made of several layers manufacture, a cushion layer being provided between the inner and outer layers and wherein the outsole can be made of several layers, which e.g. are preformed (French patent specification 1,507,941).

As already mentioned, these well-known ski boot trainings were able to do so or the arrangement of the size setting and the slip-in slots are not satisfactory, because these previously known shoes of the foot shape are not flawless and individual let adapt, but often either pressure points, leaks, excessive Tensions or the like. Were present, or the production was too complicated and was too expensive.

In contrast, the object of the invention is to create a ski boot, the essential parts of which can each be approximately completed on their own and for each part a perfect and easy shaping and completion possible should be and whereby by means of a simple attachment process the two parts can be connected to one another, after which the ski boot is essentially is completed. At the same time, it is an object of the invention to provide a ski boot create that in terms of sole strength at a significantly lower weight A greater rigidity is obtained, as does the upper part of the shoe with a lower weight should have higher thermal insulation values and, viewed overall, the shoe against Penetration of water and dirt must be secured so that the ski boot also has one receives full use value.

Furthermore, it is an object of the invention to ensure that the To achieve the shoe on the foot without any special subsequent measures should be required, and it should also be achieved that the respective Foot size and foot shape can be adapted to a general, if possible single, shoe size should and, in particular, the restraint of the foot can be individually adjusted, aleo on individual games for themselves iii their tension depending on the requirements of skiing should be made possible.

It is also an object of the invention to achieve that with a few Handles - if possible only with a single handle from a rest position, e.g. XX while waiting or when driving up in the list into a departure position conceived on all sides can be passed over, whereby it is also the object of the invention at the same time, to train the shoe essentially so that it is easy to slip it on and then the complete closing is made possible in a few simple steps.

Here the invention is based on a ski boot made of plastic or the like. The invention consists in that a grid-shaped or the like. Trained, spatially deformed, essentially stretch-free stiffening insert in or on one or more of the sole part made of plastic or the like and / or the layer or layers forming the upper part is e @ n and / or molded on.

With this training it is now possible to use a ski boot in this way produce that on the substantially adapted to the mold and substantially non-stretch formed stiffening insert part, which each for itself both for the sole as well as for the upper part, e.g. each on the outside is a hard plastic in the hand lay-up process, in the injection molding process Or the like. Is applied, this plastic in the stiffening insert can penetrate due to their lattice-shaped training and therefore an intimate Connection is received. This makes it possible to have a very thin and very resistant Layer to achieve. In the case of embedding the stiffening insert til the outer resistant layer on the inside of the now manufactured Upper part designed as a thermal insulation and / d the stiffening layer Layer are applied, which in the interior with a corresponding padding can be provided.

By this measure, namely the separate, spatially deformed production It is the sole part with subsequent application of the stiffening layers possible to produce lightweight shoe parts, in particular the lower part of the sole with a very tough, abrasion-resistant outer layer, as well as one of the Stiffening and / or thermal insulation layer adapted to the foot shape inside while the upper part of the shoe is made of a plastic, e.g. with a high proportion of plasticizers can be made so that the behuh upper is substantially extensible is, especially in the areas of the necessary freedom of movement, So in the joint areas the plastic is applied with a higher softness can be. The stiffening insert can be embedded in the plastic take place in such a way that the layer, which for example, is formed as a hard running layer is, in the case of the sole part as a stiffening insert, completely absorbs, while with the formation of the outer layer as a colored and soft plastic layer, in the case of the manufacture of the upper part only a small penetration depth in the stiffening insert is required, 90-that for the next on to be applied thermal insulation and / or stiffening layer or padding layer there is enough space. After both the sole part and the upper part in each case for itself at least one side are made open, after which they are then can be connected to one another along a joint gap.

In a further embodiment of the invention, the stiffening insert is provided to be trough-shaped in the area of the sole part, as well as the stiffening insert e in the area of the shoe upper part of several, through elastic intermediate areas to produce separate single stiffening inserts. In particular, it is provided the plastic overlay on the stiffening insert and / or the stiffening insert even in the upper part of the shoe with high elasticity and in the lower part of the shoe with low elasticity train, so that in each case a minimum wall thickness with a maximum more favorable Material selection can be achieved, Ss is further provided, the stiffening insert made of locally deformed expanded metal provided with slots or similar openings, To produce lattice metal, glass lattices, plastic lattices, perforated sheets or the like, so that with such designs the stiffening insert in the course of the shaping process by deforming the lattice structure of the stiffening insert a simple spatial Deformation in particular of the upper part of the shoe and the tub-shaped sole part without wrinkling and without attaching cuttings, cut-outs, or the like. is possible. The stiffening insert can be made of expanded metal, with expanded metal one not only made of metal, but also of plastic or other suitable material existing flat plate is to be understood in which can be introduced at predetermined intervals, slots, recesses, so that when spatially deforming these recesses without any particular flow of material the deformation can take place, so that e.g. in the case of a collapse the individual expanded metal parts when belting up the sole edge the openings the bitter structure become smaller, while e.g. when the upper part of the Shoe the openings in the lattice structure can be made smaller. It is However also possible, this stiffening insert made of woven, knitted, braided, knitted fabrics z.3. from crosshairs or from fiber fleece, these structures are each spatially deformable by themselves and are made of metal, high-strength plastic or the like. In particular thermoplastic a can receive further relief of the shaping. On this spatially deformed As already mentioned, stiffening insert can be applied to the individual layers later inside or outside can be applied.

It is particularly advantageous if individual areas of the upper part are divided into individual areas of the stiffening layer so that the individual Areas of the upper part are movable relative to one another, which is particularly important It is an advantage if, for example, individual stiffening inserts in the instep area and / or in the shaft area connected to the rest of the shoe upper part by elastic areas of the upper part of the shoe are, so that by bridging these elastic areas, by means of corresponding Latches, these stiffened areas outwards or inwards can be moved, so that if you let go of the tension locks, in particular by introducing a plastic pre-tension in the opening sense so the stiffened areas curve outwards so that it is easy to slip on and off of the foot in the shoe is guaranteed.

Further advantages and features of the ski boot according to the invention training and in particular the handling of the method according to the invention are based on the following Description owie from the patent claims, all individually characterized Characteristics alone or in any combination are the subject of the protection request are.

The ski boot training according to the invention is illustrated below on the basis of several Piguren described, each of which has cross-sections through the front shoe area, s.B. in the area of the shoeist and which ii essential the structure of the ski boot according to the invention can be recognized. Here are in the individual Cross-sectional representations of different embodiments in more detail explained, in each case the structure of the ski boot according to the invention and the structure according to the invention Method of describing komat.

According to Figure 1a, the sole part 1 is approximately trough-shaped, the actual running sole essentially corresponding to the associated Ski shape, e.g. is made with a constant width on the running side and in the area of the widenings, the trough-shaped part with inclined chair parts 1a one or both sides obliquely outwards, upwards and outwards according to the desired shoe width is guided una being approximately in the middle of the whole Front part height, a parting line 1b arranged on the shoe and area of the parting line Ib the sole part 1 is set off with a circumferential overlapping edge 10 and a recessed circumferential insertion groove ld forms, in which with in.a accordingly trained Einfdgebund 2a of Qbert 2 engages.

The sole part 1 consists essentially of a flat case tub-shaped stiffening insert 7b, which is made of a woven fabric, braid, knitted fabric a crosshair structure, made of expanded metal, made of a perforated metal molding, Plastic molded part or the like. Is produced, which is essential in each case is trough-shaped and laterally raised circumferential edge areas 1. has, which ii essentially follow the overlapping edge 1o of the sling part 1. The sloping sole parts go in the area of the heel, as well as in the area of the Shoe tip, not shown) each in appropriately shaped shoe tip parts, Paragraph parts about how these will be explained later in their training, whereby these shoe tips and heel parts essentially correspond to those that act there Ski binding backan are designed and in particular appropriately designed receptacles, Grooves, too take plates, holding studs or the like. Have which in Figures 20 and 4 are indicated by way of example.

The sole part 1 is in the inner lower wa @@ en-shaped 3 area understand with a stiffening and / or thermal insulation layer 15, which upwards is covered out by a cushion layer 29, which is essentially the puss shape follows and which can be inserted, jammed or e.g.

be firmly connected to the sole part 1 by a foaming process can.

Here, in the figure @@, the cushioning layer 29 is proportionate dtinn and the stiffening and / or thermal insulation layer 15 are shown relatively strongly. However, it is of course possible to make the cushioning layer 29 much stronger, thus to train with a higher upholstery edge, the stiffening and / or Thermal insulation layer 15 is withdrawn accordingly. But it is there too possible to form the two layers merging into one another, so that as c e.g.

the stiffening and / @ the Wärasdämmschioht 15 in their on the Schlenunterseite adjacent part has a high strength and in its area trimmed to the foot has a low strength or a high degree of resilience.

The sole part 1 is manufactured in such a way that the stiffening insert 7b, which can be made from a flat piece of expanded metal, for example the stretching process is shaped like a trough, after which the circumferential Outside of the expanded metal and / or the inside with a plastic coating 1g. e.g. with a glass fiber-containing or fiber-containing or other stiffening or Layer containing abrasion elements is provided, s @ that the stringed sole part 1 is trough-shaped in itself and is very stiff and in particular on his Run down to an extraordinary hardness.

Due to the heat and / or stiffening layer that is still applied 15 there is a further stiffening and in particular a shaping for the Foot support enables how these from those to be described later Figures Im, 1n, 10, ip, can also be seen, for example, such that the tip area of the shoe according to Pigur 3 is formed deeper, while the heel area opposite the actual Laufschle is raised.

The upper part 2 is formed in a corresponding manner, and also here again a circumferential stiffening insert made of expanded metal or the like 7a is provided which, starting from the mentioned parting line Ib, laterally after at the top almost until it is pulled over the top of the foot and one almost Has loop-shaped contour shape, such as this, for example, schematically in Figure 2s is shown.

Here, too, the expanded metal or the stiffening insert, which In the hall of the upper part 2 also a fiber fabric, for example made of polyester fiber or The like., Made of high-strength braid, knitted fabric or the like. Can be made by encased by a plastic coating 2g. A hard outer layer can also be used only on di to di. Stiffening insert 7a can be applied while the inner layer Which plastic is essentially made of, s @ that in the surrounding area le is not only stiffened by the insert, but also by the applied Plastic takes place, while in the overlying flap area 2c this is essentially elastic iEt and also separated there by a slit s in the middle of the shoe area will. The two flap areas 2c are ii areas of the slot 4 only so far preferred in the dorsum of the foot that a free slip of the foot into the Shoe is guaranteed.

The two flap areas 2c can be sucked together by means of closures 5 are, as indicated in Figure 2a, and with only a single closure 5 is provided in the forefoot area, while z.3 in the upper shoe area. above the ankle area a further single closure can be arranged, whereby it however, it is possible, as indicated in FIG. 2b, to have several narrow closure parts z.P. 2,3, or 4 in the front @@@ bere @@@ and also several narrow locking parts in the Provide upper shaft area.

In the hall of the arrangement of a single closure part, it is possible this so auszubilaen that in connection with the stiffening insert 7 a torsion-free Tensioning of the two flap areas 2c can be achieved and thereby an approximately rigid shoe upper structure is achieved in the front foot area. Of the Slot 4 is covered at the bottom by a heavily padded tongue part as shown in FIG 51, which is designed to be elastic both lengthways and transversely, and which is with Oversize is fitted into the upper part 2, so that it is on all sides on the inside of the shoe upper part 2, in particular on the inside of the two flap areas 2c applies and so a complete sealing of the slot 4 is achieved.

The edge 7d of the stiffening insert 7b engages in the area of the parting line ib over the corresponding insertion groove ld over the sole part so that a circumferential Separation point of the two shoe parts is created, with the part protruding downwards 7c of the upper stiffening insert 7a the mentioned, upwardly projecting part 7d of lower stiffening insert 7b rear engages and so in the area of the Z-shaped joining gap, which egg. Slebstelle, weld or the like. Is formed, a flawless one Overlap of the two shoe or Stiffening parts results.

The inner area of the upper part not yet covered by the tongue part 51 2 is provided on both sides with a cushioning layer 29, so that the foot as a whole of the stiffened upper part 2 or stiffened sole part 1 kept at a distance on all sides is, wherein the cushion layer 29 also serves as a thermal insulation layer.

As can be seen from FIG. 1 a, the width adjustment can of the shoe also take place through a smart design of the tongue part 51, with a width adjustment part of different thicknesses depending on the width adjustment required 51b can be inserted into the tongue part 51.

At the same time it is shown in FIG. 1a that in the two flap areas 20, which adjoin the shoe edges, further stiffening parts 27 than Closure inserts 27 are arranged, which in the area to be closed Cattle are molded into the plastic molding of the shoe upper part 2 and with corresponding vases protrude outwards, in which the individual levers or buttons of the actual Shoe closure can be molded or attached. This eliminates the Subsequent fastening of the locking parts customary up to now, whereby mostly the individual base plates are very bulky. Furthermore, through the going, however elastic closure insert 27 reaches that the shoe edges between the local individual locks cannot gape. In particular, this is training then an advantage if there is only one lock for the front or

is provided for the top, with this training bai the closure insert 27 can also continue up to the upper shoe shaft area As can be seen in FIG. 1b, after the closure 5 is released, jump or the closures 5, the two lobe areas 2c of the upper part 2 under the effect an applied internal prestress upwards, with the tongue part on the same side 51 is taken upwards so that it can be easily slipped on. That The two flap areas 2c can spring open in such a way that these flap areas of the upper part 2 can already be produced in the position shown in FIG. so that they are only bent together under the constraint of the locks or the lock and each time they return to their original position after releasing the lock jump back. However, it is also possible, as is not shown in more detail, special shaping spring elements 84 to be molded, as indicated in FIG. 1b are, whereby these spring elements 84 can be designed as individual spiral springs, which are originally formed in a straight shape and so are the two lobster oaks 2c to be held in spread-apart positions, but under the effect of the shoe fastener or the shoe fasteners bent together will can.

The forward-facing part of the slot can also be analogous to this 4 be provided with prestress in the area of the shaft part 3 of the upper part 2 in such a way that that the two forward flap areas 2c of the shaft part 3 after loosing Ges upper closure 5 under the influence of its internal bias to the outside jump and thus enable comfortable slipping.

Here, too, either the flap parts can be shaped so that they return to their original stretching position, or there can be additional stretching Operator elements, as mentioned earlier, be molded.

After the closures 5 as rocker arm, clamping lever closures or Like. To be designed, it is possible in a simple manner, the feeding Overcome bias of the two flap areas 2c and the two gaping Tab areas 2c of the upper tail 2 together, thereby simultaneously the tongue part 51 is pressed downward.

In an analogous way, you can also execute after the later Figure 2b to be discussed a rearwardly directed insertion slot can be provided, with a shoe flap that opens to the rear or diagonally to the rear of the shaft part 3 is provided, which is provided with an internal bias, which works in a stimulating sense, so that here, too, it is easy to slip in is made possible, while the flap pretensioning, which acts in the opening sense, is also possible in a convenient way when actuating the rocker arm locks, which have a large Gear ratio result, can be overcome in a simple manner and thus the both gaping shoe flaps can be closed.

To the figure ib it is still to be trotted that the shoe is made in one piece is, with a single trough-shaped, but he @ raised stiffening insert 7 is provided, which extends up into the tongue area and also here in turn in the tub-shaped sole part 1 a Wä @ medämm-, stiffening and cushion insert 15 is provided, while the tongue 41 herebe @ as a molded part is formed, welehe sowo @ l equipped with a single shape size Injection mold adapts to the outside, as well as with its Ibbebseite the respective is adapted to the individual foot shape, so; 3 this tongue allows for easy width adjustment or a simple foot size adjustment is made possible. Again, here are in the lateral areas of the raised tub-shaped sling part laterally Padding layers 29 provided, which are connected to the tongue part 51 and this tongue portion 51 under elastic deformation downward onto the two Upholstery parts are pressed on, which due to their high slackness, however, are not Edge pressures can result on the clamped foot.

Another embodiment of the ski boot is shown in FIG. 1c, whereby the ski boot, as already mentioned, is not deformed in two parts, but in one part is and wherein, however, the stiffening insert 7 is formed in two parts. Here is a lower stiffening insert 7b, welehe is trough-shaped. in turn provided with a plastic coating Ig, this plastic coating according to the figure lo is applied on both sides to the stiffening insert Tb, weloh. also here again is trough-shaped and wherein the plastic coating at the Beltenbereiohen of the stiffening insert 7b in the area of the upper stiffening insert 7a of the upper part 2 continues. Here are the two stiffening inserts 7a and 7b approximately in the lateral shoe area at a distance, with the there applied plastic in the above-mentioned transfer device @ I have a bellows-shaped bending zone 20 forms, wcb this is formed approximately zigzag or wave-shaped and Due to this elastic bellows shape, the two shoe parts can therefore be moved relative to one another night. by means of a tensioning strap 21 which is crashed onto the lower Scjihtell 1 on both sides is and which has a clamping lock 2 @ in its middle regions, can the two halves of the strap 1 are annt together, so that under decorative tensioning effect the two bellows-shaped areas 20 between the upper and lower part of Shoe are pressed together and so the interior of the shoe is reduced and hlerdu @ en the upper part 2 is pressed onto the foot, the bellows-shaped bending zones 20 can also have an inner, molded-in, in a decreasing sense acting bias, so that after loosening the tension lock 24 the upper part 2 lifts itself automatically from the lower sole part 1 and so too here again it is easier to slip on and off.

In the interior of the shoe, according to FIG. 1c, there is an inner lining part 18 provided, which is approximately the outer shape of the foot with the overlaid Clothing is adapted. Here, support pieces 16 are arranged in the interior, aul which; the inner lining part 18 rests at a distance. To now the. between the Inner lining part 18 and the own upper and lower part existing interior to be able to fill out and in order to ensure a flawless adjustment of the To achieve total beauty to the respective foot shape is in the space in between between inner lining part 18 and sling part 1, as well as upper part 2 in, for example, half-stretched State of the toggle fastener 24 through a filling opening arranged in the sling part 1 17 E.g. molded plastic, which has all cavities opposite the soles part 1 as well as the upper part 2 fills out.

The adjustment process can be carried out in such a way that the inner lining part, 18 which, as already mentioned, is tubular, to adapt the Shoe to the respective foot size after pulling over the foot in the interior is placed on aie support stack 16 attached to the lower part, or it wirc first the inner lining part 18 is placed on the support pieces 16 and then slips The person for whom the shoe is intended is inserted into the inner lining part 18. Dansch is in between the upper part 2 or sole part 1 and the inner lining part 18 still existing interior of foamable plastic or the like. White plastic material or the like., a fiber mixture or the like Filling opening 17 blown in, injected or poured in. After this hardening or partial hardening or foaming of the introduced intermediate layer the shoe after the operator has opened the spaun fastener 24 completely be withdrawn, as already mentioned under the internal bias of the bellows-shaped Bending zones 20 of the upper part 2 lifts off the sole part 1, so that it is easier to slip is.

Depending on the setting of the tension lock 24 during the foaming or. Adjustment process, the foot restraint can be chosen arbitrarily, with further Tightening the tension lock 24 a complete tightening of the foot, e.g. for The descent can be achieved by simultaneously removing the elastic liner is compressed during the partial release of the tension lock 24 the restraint of the foot can be reduced to a waiting position. Of the Tension lock 24 can be used as a conventional folding lever, rocker arm, tension lever, toggle lever lock or the like. Be formed.

By appropriate selection of the injected or foamed intermediate material, furthermore by appropriate choice of the stiffening and / or thermal insulation layer 15 in the tub-shaped sole part, in the lower part of the shoe area a through the lower filling opening 17 introduced harder material are injected, which e.g. contains a larger proportion of fibers, while in the area of the upper part of the shoe through the upper filling openings 17 also formed there a softer, cushioning, or better thermally insulating cushioning material, in particular one made of foam existing upholstery part can be introduced in the form of an intermediate filler 19 can. It can also be proceeded in such a way that in addition to the side of the Inner lining part 18 of this relatively by the interposition of a foam layer thin shoe end part or is kept at a distance from the bellows part, so that excellent thermal insulation is also achieved there.

In FIG. 1c or also in those described above or below Figures, the inner plastic overlay is proportionate to the stiffening insert shown in bold, but it is provided in the practical implementation only one -relatively thin stiffening insert, which e.g. made of perforated sheet metal, is made of expanded metal or of deformed fiber crossing structure, with to provide only a thin layer, e.g. with glass fiber reinforced plastic, while the inner layer made of other fibers e.g.

textile character or e.g. synthetic fiber with a higher melting point Property or with better thermal insulation or with twisting or crimping Or the like. Made of loosened plastic and furthermore in the upper Shaft part 3 of the plastic, in particular the outer plastic, on the reinforcement insert is applied with an increased amount of plasticizer, as well as the amount of plasticizer held particularly high in the area of the lateral bending zones 20, that is to say the bellows can be. This method of applying the coating to the actual smoothing layer can be used both in the hand lay-up process as well as in the machine spraying process, furthermore in the machine spraying process in general, as well as by free spraying using different spray nozzles, especially with controllable side nozzles, respectively.

with controllable order area, or using an injection mold can be achieved with multiple injection screws.

It is of course a prerequisite that the various The plastics used bond with one another in the areas that abut one another.

In the figure 1d a further embodiment is shown where also here again a trough-shaped stiffening element 7b is provided, which is surrounded in particular on both sides by a plastic layer and in which The tub-shaped interior of the sole part 1 has a thermal insulation and / or stiffening insert 15 is introduced, which on its upper side by a lower inner lining part 18a is covered0 The lower part of the sole 1 is followed by an upper part 2, which according to the embodiment of Figure 1d only in its central area has a stiffening insert 7a, as can be seen from Figure 3 and which is pulled up over the boot area and is also provided in the toe area is, so that overall t the front shoe part carries a stiffener.

The stiffening insert indicated in figure id only with a small width 7a can, however, also extend over the entire width of the upper part 2 and if necessary, be in one piece with the lower stiffening insert 7b.

In the interior of the upper part, which by spraying onto the stiffening insert, also by spreading plastic on the stiffening insert or the like. can be produced, as will be explained later, is an inner part 22 attached, which is only formed in the instep area and an approximate saddle-shaped, with the upper and lower seams of this inner part 22, as can be seen from Figure 3, by the subsequent, on the upper part 2 attached upholstery parts are longitudinally guided. This inner shoe part 22 instructs its underside in turn an upper inner lining part 1Ub, which upwards merges into an intermediate filler 19, which is a foam layer or the like. is formed, wherein the entire inner part 22 forms a support bridge at the top and thus a saponifying outer layer provided with a reinforcing insert 22a 22b results. This entire inner part 22 can opposite the upwardly extending Reinforcement insert 22q in the instep area by means of a tension lock 24 in the direction nuf the sole part, i.e. pressed onto the foot in between.

However, it is also possible, as shown in FIG is, by means of cables 33, 34 engaging the longitudinal sides of the inner part 22 to tension the inner part 22 obliquely downwards backwards against the heel, whereby through corresponding rope guides 34 a deflection takes place in such a way that by e.g.

arranged in the ankle area common toggle fastener 35 of the entire Inner part 22 can be tensioned, and depending on the setting of the individual ropes the pressure in the front, or upper, or rear part of the inner part 22 is different can be set high. It is quite possible, e.g. the leaning area less clamped than the instep area.

In Figure 3, which, as already mentioned, a longitudinal section through a particularly advantageous embodiment of the invention Shoe represents, is also as already mentioned, the lower sole part 1 with a tub-shaped stiffening insert 7b provided, which in particular in the heel area of the shoe is pulled up or lifted. In the cap area is in the interior of the cap a cushion layer 29 is arranged, which with its rear Limitation forms the aforementioned guide 31 for the inner part 22 and where the Inner part 22 adjoins this boundary in an approximately true-to-shape manner and wherein also a bellows-shaped bending zone 20 in the area of the ankle joint is provided, the front limit of which serves as a guide for the inner part 22, so that the latter moved longitudinally between the end edges of these two padding inserts is and can be tensioned within an adjustment range 22c shown in FIG is. At the same time it can be seen from Figure 3 that the upper part 2, which according to the embodiment of Figure 2b can be divided in the rear area, wherein this parting line 3a from FIG. 2b either in a single caer in a double arrangement can be removed so that the rear part of the shoe can be folded out at the rear is and where the resulting slots are covered by a sleeve 25 can, which, as can also be seen from Figure 3, around the entire ankle area can be stretched around or, as can be seen from Figure 2b, only is stretched around a portion of the upper shoe upper area.

From Figure 3 it can also be seen that the stiffening and / or Heat insulation layer 15 is wedge-shaped, so that there is an increased heel position results. It can also be seen from FIG. 3 that in the area of the paragraph and Edge protectors 44 molded onto the cap or contact surfaces for the ski bindings, anti-slip devices, or engagement surfaces for the ski binding jaws can be arranged, such as these The arrangement can be seen better from FIG. 4 f; ir the front shoe beretch.

Another embodiment of the invention is shown in FIG Ski boots shown in cross section, also here a tub-shaped one Sole part 1 is provided with a corresponding trough-shaped stiffening insert 7b is, wherein the tub-shaped interior is upwardly through a cushioning stiffening and / or Thermal insulation layer 15 is covered, also here is again provided subsequently to form a bellows-shaped bending zone 20 on both sides of the trough-shaped sole part 1, which upwards into an upper part 2 provided with a stiffening insert 7a transforms. On the shoe part located below the bellows-shaped bending zone 20 a tensioning strap 21 is attached on both sides, the upper ends of which by means of a Tension lock 24 can be clamped together with adjustable tension. In the upper part 2 a second pliable inner layer 36 is formed at the same time, which by a gap 43 from the stiffened outer upper part 2 at a distance is held.

In the inner region of the pliable inner layer 36 is a cushioning layer 29 arranged. Because the pliable inner layer 36 is only applied to the lower Edges of the stiffening insert 7a of the outer upper part is hinged, wherein In each case, the bending zones 20 begin at the same time in these articulation points, it is possible by tightening the two tensioning straps 21 by means of the tension lock 24 a lowering of the stiffened upper part 2 by compressing the bending zones 20 to achieve, while at the same time under bridge-like tensioning of the flexible soles Inner layer 36 achieves an all-round adaptation of the foot clamped there can be.

The flexible, slack formation of the inner layer 36 ensures that without increasing the specific contact pressure, the former is evenly applied to the entire Adjusts the foot surface so that no single pressure stalls are possible. In this version one or more tension locks can be provided.

Here, the upper part of the shoe 2 is provided with a reinforcement insert that runs all the way around the side 7a, which is embedded in the shoe upper part 2 and which in the area the groove of the sole part is bent outwards so that the into the groove of the sole part 1 engaging circumferential edge 49a of the shoe upper 2 is well supported. As a result The upper part 2 can adjust to the internal prestress applied during manufacture previous compression introduced into the circumferential edge 49a with sniffing and is then held by its own preload, which is in the area of the Fußgespaltes mutually engaging stiffeners 7a, 7b with regard to add their stiffening effect and at the same time as a result of the rear.

grip of the two profiles creates a very solid connection between the two shoe parts 1.2 result. The thermal insulation and stiffening layer 15 can be in the trough-shaped Sole part 1 are introduced beforehand, this stiffening and / or thermal insulation layer here 15 surrounds the stiffening insert 7h on all sides and thus provides particularly good adhesion between thermal insulation layer and stiffening layer 15 is achieved, at the same time the thermal insulation and stiffening layer 15 through the circumferential edge of the shoe part prevented becomes from the corresponding in the case of heavy use Jump out the groove of the sole part. The joining columns can be made by glue, by welding, by thermoplastic deformation or the like. Or by incorporation additionally stiffened, connected or the like by sealing material.

The actual thermal insulation and / or stiffening layer can also be applied 15, as can also be seen in FIG. 1i, an additional cushioning layer 29, with a cross-section adapted to the shape of the foot, with the side parts cter cushion layer 29 are pulled up and in particular with bias place against the lower side edges of the upper part, so that after opening the tension lock (s) 24 under the effect of the ones introduced in the support areas, in the opening sense acting bias, the shoe upper part 2 in the area of the The slot spreads and likewise the padding 29 introduced into the tongue part 51 as a result their acting against the downwardly pulled down side parts of the tongue part, elastic preload force pushes the tongue part 51 upwards. After solving the Closure 24, the foot is released from its restraint on all sides and so one in particular bute ventilation achieved while after tensioning the or the Tension locks 24, as a result of the all-round elastic clamping of the foot and the upholstery edges pressing against each other achieve good restraint of the foot will.

In the figure li is also shown that each of the top and / or also the lower edges or all outer edges 7c, 7d of the stiffening insert 7a, 7b each with a continuous wire, Pormdraht, plastic wire or Like. To a further stiffener 86 can be provided to in particular one To achieve dimensional stability of the stiffening insert 7b even if the latter z.t. consists of thread crinkles, plastic or the like. So that a very light stiffening insert 7 can be produced. It is also provided that the upper areas of this upper part 2, as already explained in FIG. 1a in certain areas, especially in the instep area and in the shaft area slotted to form, e.g. the left half of the upper part 2 is made in two layers and in an outer and inner Zu8-band 47a, 47b is dissolved and this shaft part, for example, according to Figure ib with an upward can be provided in the opening sense acting bias.

On the other part of the shaft is in the area of the slot, which is can also extend only over part of the upper part 2, a tension lock 24 articulated, which by means of a roll bar 24a in the between the outer and. inner drawstring 4ta, 47b formed slot engages, so that after tensioning of the tensioning fastener 24, in particular, the inner, thinner drawstring formed 47b on the correspondingly designed roll-off bracket 24a of the toggle fastener 24 can roll and in particular only the inner thin part 47b of the shoe upper part 2 is tightened so that it stands out from the outer part. The two tops reach under each other after tightening the fastener, whereby in the area of the Slit a tongue part 51 is provided which extends into the shoe cap area and can run down to the ankle area and a corresponding one to each has shaped foot cross-section adapted shape.

In the examples discussed so far, it is assumed that the Stiffening insert carries a plastic layer that is the same on both sides. However, it is also possible according to Figure 1k, the stiffening insert 7, which e.g. as an expanded metal molding, Fabric molded part or the like, as will be discussed later, is formed, with one attached in approximately its middle plane, in the form of an as Soap skin-responsive skin layer 53 to be provided, whereupon this skin layer 53, which protrudes from the parts of the stiffening insert that protrude to the outside a hard, tough and wear-resistant plastic layer 54a is applied can be, and this hard-resistant and wear-resistant plastic layer 54a is provided in particular in the sole area, while in the upper area the applied, sprayed or poured on or the like. Order made can change into a softer plastic. On the inside of this now produced and molded part separated by the skin layer 53 can be one with a high thermal insulation value, in particular with a highly elastic property or plastic layer 54b formed with a stiffening property is applied be, the protrusions protruding into the two plastic layers e.g. in the case of expanded metal, the individual upward arched wire or band areas, or in the case of a woven or knitted fabric, the respective after both sides of the thread parts are an intimate connection between the two Plastic layers 54a, 54b result and the skin layer 53 only then is necessary, for example, when working with coarse fabric or pouring grid spacing is what e.g. also in the form of the use of crosshair structures as reinforcement insert It is important when the skin layer 53 also acts as a connecting layer is used for the crosshairs, but it is in the case of a fabric or Knitted fabrics with a low mass: a layer of skin is not absolutely necessary 53, but rather it is possible to use the two sides of the stiffening insert to be provided with different plastic layers 54a, 54b or the like.

In Figure 11, an embodiment is shown, which in particular for one-piece or similarly manufactured shoe molds, e.g. manufactured by injection molding applies, the stiffening insert 7 in the case of twisting thermoplastics through corresponding heating can be pressed into the outer plastic layer 55, so that an intimate connection is also achieved here, especially when the Stiffening insert 7 provided beforehand with a coating that is easy to connect is. In an analogous manner, a heat-insulating and / or cushioning layer 15 can again be provided be, which are both one-piece and single-layer as well as multi-layer can be and which both in planar form, as well as in the respective foot cross-section adapted shape can be made.

In the figures im to 1p, the design of this stiffening and / or Thermal insulation as well as cushioning layer, which so far generally with the Reference numeral 15 is shown, wherein the sole part 1 is based on the embodiment connected according to the figure ig. It is provided here that the stiffening insert 7b of the sole part to be provided with a circumferential edge, which obliquely upwards Has drawn sole parts la, with a circumferential in the area of these sole parts Nut if is provided, which is already described in connection with the figure ig Engages in the upper part, e.g. the thermal insulation and / or cushioning layer 15 in the trough-shaped sole part 1, e.g. by foaming in a rigid foam with a more or less large fiber content or by pouring a stiffened one Glass resin insert be formed, but in particular it is provided that the stiffening and / or To produce a thermal insulation layer e.g. as a foamable plastic, whereby this foamable plastic upwards through a prefabricated covering layer of cushioning 29 can be covered and it is provided during the manufacture of the ski boot, the still liquid resp.

In particular, in connection with the figure ip, the heel part is provided to pull upwards, furthermore to arch through the ball area, the clamping area pull up, in particular depending on the orthopedic pressure absorption possibilities of the foot through the formation of the respective intermediate layer, density and rigidity the pressure receptivity of the individual areas can be set cold, which is particularly important is important in the toe area, as the toe pressure is particularly low when descending is given, but after moving by loosening the clamping device the to achieve a high clamping pressure required low spring action of Padding can be compensated for by releasing the tension.

In the figure lp is also shown that the stiffening insert 7b can be pulled up in the front and rear shoe area and that there a fan protector 44, engagement devices for ski bindings, running parts or the like. are integrally formed, these parts being so one and formed or already as a component of the stiffening insert 7b can be designed so that they the wear on these particularly subject areas to step onto the surface of the ski boot sole without but protruding above this surface, so that hereby a smooth and yet abrasion-resistant and tear-resistant shaping of the entire ski boot is achieved.

From the figure ip it can be seen - that by the formation of the sole part 1 with the stiffening insert 7b described above, it is only possible to remove the lower surface 87 Aes sole part only rest on aem ski at the orthopedically required points in order to achieve precise ski guidance, safe release moments of the To ensure binding and also to make the sole better able to walk.

The advantages of the stiffening insert according to the invention, which how already mentioned, as a deformable expanded metal layer, as a fabric, thread-crossing structure Or the like. Is designed in connection with Figures 1q, ir, is, it explained. It is provided here on the reinforcement layer on one side Side e.g. by needling, flocking, sewing or similar. To form a plore layer, which are formed both with pile loops 80b and with free-ending pile threads 80a can be and where, e.g. in the case of needling, individual tufts of tufts in the spaces the expanded metal layer or the fabric layer, crosshair layer or the like.

be pushed in such a way that the deflection points are only slightly off the reinforcement layer 81 step out, so that narh the layering of this The individual Msserbundel fixed to the reinforcement insert only as the outer layer 81 are connected, with the appropriate spraying, spraying or the like. the coating also on part of the inside of the reinforcement insert 81 can penetrate how this is explained in the figure iq.

By appropriate shearing, i.e. shortening the free ends, or Compression of the fiber ends can now adjust the inner shape of this as a padding and Thermal insulation layer acting fiber layer are used, the outer ends through a lining layer 28 may be covered, which at the top or also at any point with the actual outer plastic coating of the reinforcement insert 81 can be connected by sprinkling, gluing, welding or the like.

In the case of the formation of the pile threads 80a from thermoplastic materials can be shaped in a simple manner by heating a suitably shaped Stamp take place as shown in the figures ir, 1s, lt, and where in the case of production according to FIG. ir those introduced into the reinforcement insert 81, E.g. bow-shaped fiber bundles originally equal height fiber parts by pressing on of a forming die are provided with diversions of different strengths, with im In the case of a slight deflection 83a, a high cushioning effect and in the case of a strong one Deflection 83b of the free ends has a relatively low elasticity of the cushioning layer It is provided here that the lower deflections 83c of the fibers in the Reinforcement insert 81 by gluing, welding, spraying or dipping to be fixed in an adhesive plastic covering.

According to the figure ts can also be provided in the fabric, knitted fabric or the like formed reinforcement insert 81 to tie in loop-shaped pile threads 80b, whose original height 82 which is also determined by a die, depending on the required shaping or indentation depth bent or into loops, loops, Widenings or the like. Are deformed, as shown in the figure is. The outer coating can be subsequently applied to the pile fabric or

fabric, knitted fabric or the like made with pile loops Reinforcement insert 81 can be applied by dipping, spraying or the like, being the back of the Stiffening layer different can be made high, as shown in Figure 1s.

In the case of using, for example, thread loops laid in a zigzag pattern one side of the thread loops 80, which is produced as a flat structure can be coated with glue, with a stiffening one Find fabric, a stiffening insert or an expanded metal layer use can, with then the other side of the loop-shaped, primeval zigzag or serpentine laid threads by applying a forming stamp accordingly is deformed.

It is a prerequisite here that the pile threads 80a are loop-shaped Threads 80b consist either entirely or partially of thermoplastic material. This type of cushioning layer can be used in all of the aforementioned forms of training can be found in connection with the reinforcement insert as well as afterwards applied cushion insert, which is attached to the originally stiffened shoe uppers or shoe bottoms can be applied, so that e.g. in the case of the figure, so in the case of using a pile fabric it is only necessary that To provide the underside of this fabric with the aforementioned reinforcement insert 81, subsequently in the form of a footbed or the like pressed onto the free loop ends and so a different height of the loops can be achieved.

In FIGS. 2a to 2f, further developments of the inventive Ski boots are explained. According to Figure 2a, the stiffening insert 7 is in the middle area of the upper part 2 provided with a recess, wherein in the area This recess of the upper part 2 has a slot 4 or the like. Which up to run over into the shaft part 3 or into the ankle area in the usual way can. However, it is also possible, as already mentioned, to make this slot elastic Train bellows. A toggle fastener 5 can be used in the instep area as well as be provided in the ankle area. It can but also several Tension locks may be provided. To increase the mobility of the shaft part 3 slots 13 are provided in the stiffening insert 7a. Here runs from the Slots 13, starting from the stiffening insert 7a in the shaft part 3, are drawn upwards Tab 7e further upwards until almost in the area of the upper edge of the shoe 6th

As already mentioned, it is advantageous if in outer circumferential Areas of the upper part of hard plastic is applied while in the subsequent Area of plastic e.g. with the addition of plasticizers in a softer area passes, so that in the lower shoe part a total of a much stiffened to the upper shoe part a substantially elastic shaft material is available. The upper Shoe edge can according to Figure 1 by a shoe edge 6, which as padding and serves as a seal, to be completed in the usual way.

As can also be seen from FIG. 2a, the stiffening insert 7a be pulled up in the upper part 2 in different heights 8, so that in the essentially completely stiffened or almost stiffened cap area or heel area Depending on the respective position in the shoe, it can be designed at different heights can. The procedure according to FIG. 4 can be such that the stiffening insert includes the entire shoe cap area, as a-lch the stiffening insert 7 in Sole part running parts 10, or edge protectors 44 anti-slip protection 52, which also nor with corresponding recesses or projections for the engagement of the ski binding bacia can be provided and with these molded abrasion or holding parts the surface of the ski boot without these protruding from the outlines, like this is the case with the usual ski boots, so that no injury or protruding edges are created and just as little with frequent sliding the safety binding jaws tear out the relatively soft sole edges he follows. The aforementioned abrasion parts or edge protectors 44 or anti-slip devices 52 or jaw holders can be used both for themselves in the actual shaping process, so molded in when the plastic is applied or with attached but they can also be attached to the reinforcement insert with the appropriate Spacers be attached, so that only by casting or molding the Plastic all parts are connected to one another.

For slipping into a ski boot designed according to FIG. 2a the two closures are opened, after which the shoe edges or the corresponding Flap areas 2c under the influence of the already mentioned internal bias move outwards and significantly expand the interior of the shoe. In particular is this is the case in the embodiment according to FIG. 2b, with the middle molded stiffening insert 7f, which still has an additional longitudinal stiffener 32 can carry, which between the outer Umlaufenaen stiffening insert 7 and the middle stiffening insert 7f formed elastic area of the upper part 2 acts as a bending zone 20 and loosening due to the molded-in internal prestress aer Verschaiüsse 5 pops up, or in the shaft area to v rn or to pops up at the back so that you can slip in comfortably. By tensioning the fasteners 5 these tensions, which act in an opening sense, are overcome and the corresponding one Upper part 2 pressed firmly against the foot again, whereby the amount of contact force through corresponding adjustment of the lock is adjustable. It is here expressly be mentioned that by the.

se internal prestress, which are generated both during the shaping process can, in which the shaping takes place in a spread position, as it is also possible is to put on appropriate spreading elements, like this already in context is the case with the figures discussed earlier, so that after solving the Closures the shoe pops open by itself, while with the previously usual closures After releasing the fasteners, the edges of the shoe are released with great effort had to be torn apart in order to be able to slip into the shoe at all.

In Figure 2b, an embodiment is shown in which the Stiffening insert 7 in the upper part of the shoe essentially over the whole Shoe area is arranged extending, however, this Stiffening insert 7f is arranged in the central area. Through appropriate In the training, the plastic wall covering the spacing slot 7g forms a bending zone 20, which runs around approximately the essential part of the surface of the shoe and with this central stiffening insert 7f in the region of the joint a further one Has slot 7h, in which the stiffening insert 7f then into the in the shaft part 3 lying stiffening inserts 71 passes.

This enables the middle upper shoe area to move as well as the middle front shaft area, so that by means of the in this Area engaging closures 5 the stiffening inserts in question in any Measure on the shoe interior too can be stretched. The middle stiffening insert 7f can be further stiffened by a longitudinal stiffener 32, so that under Under certain circumstances, only a single central closure 5 according to the figure 2a can be provided.

In the Auslührungsbeispiel according to Figure 2b, the upper part 2 and the Shank part 3 separated by slots 3a, with between these two slots 3a, a rear shaft part 12 is arranged, which at its lower region is connected to the lower part of the shoe via a corresponding joint. In the area of the slots 3a is arranged across a sleeve 12a, which by means of a fastener 5, both steep in this area, on the upper shaft part 3 can be pressed. The top seal is also here in turn by a Achieved cushioning shoe edge 6, which in the region of the slots 3a must also be divided, but the padding is designed in such a way that that the individual parts after tensioning the shutter 5 under the action of internal bias are pressed against each other.

In the figure 2c is a diagrammatic view of a further ski boot formation shown, wherein a two-part design of the ski boot is provided and the stiffening inserts shown translucent through the top layer are.

The two shoe parts are in the area of the parting line 2b with one another tied together, wherein the upper part 2 as well as the sole part 1 has a stiffening insert, as has already been discussed earlier and furthermore in the upper part 2 the stiffening insert can be arranged in several parts such that in the middle shoe area, like this For example, a central tensioning part 45 is indicated in FIG. 2b Arranged over a circumferential bending zone 20 up to the shaft part 3 is, wherein this tensioning part 45 can be tensioned by means of a plurality of tension locks 24. In the area of the ankle joint there is a bellows-shaped between the two clamping parts Bending zone 20 arranged so that the upper clamping part 46 against the lower clamping part 45 is movable in the area of the ankle joint.

At the same time, however, by means of the tension locks 24 individually In the ankle area or in the instep area, the bosom tension can be adjusted individually.

In the figure 2c it is also shown that in the area of the shoe cap molded-in stiffening inserts, edge protectors 44 or the like can be provided, which in the areas cooperating with the ski binding jaws from the actual Plastic molded layer step to the outside or are attached there and their surface form and at the same time special engagement openings, ball sockets, guide grooves Or the like. Can be provided for the ski binding jaws that act there.

The same arrangement is provided in the sales area, although here too in turn special insert parts which are connected to the stiffening insert 7 can stand or their components can be formed in such a way that these Insert parts in the area of the tensioner or the cheek grip on the surface of the nozzle Step outside and seamlessly form the shoe upper surface, so that it gets stuck or tearing is excluded and also with softer plastic mixtures a secure hold of the ski binding3 can be achieved without the To control shoe parts when releasing the sliding safety binding is because the inserts provide a secure hold due to the higher strength can also be achieved in the sales area, edge protectors, barrel Corners or the like. Be molded, as well as special holding facilities there for an automatic gear, automatic touring, automatic heel or the like can be, so that it is no longer necessary to use the corresponding ski binding parts to be provided with special brackets, or subsequently in a highly questionable manner To be attached in a way so that the sole surface is no longer injured when sliding off can.

In the figure 2c is also shown that the descent into the Shoe takes place from behind, with a cap-like shaft part 3b which can be folded out at the rear is, as is also explained in more detail in Figure 2e, and wherein the rear fold-out Part is connected to the rest of the shoe part by means of a bellows-shaped bending zone 20, which are essentially within the range of their elastic deformability forms a joint part and this shaft part 3b by means of a toggle fastener 24 is lockable on the other shaft part.

From Figure 2c it can also be seen that the stiffening insert 7a is arranged pulled up over the area of the ankle joint. Between two essential areas of the stiffening insert 7a, which here has a slot 13 may have or which is excluded there and where in the area of this A stretchable layer or a bending zone 20 may also be provided in the recess can.

However, it is also possible, instead of a rear, ik shaft part 12 attached slip-in slit the slip-in slit in the area of the front, that is to say to place the upper tensioning part 46 resting on the shin, with this slip-in slot both on one side of the clamping part 46 as well as on both sides of the clamping part 46 rests against the shaft part 3 with corresponding transgressing lips 14c and this part of the clamping part 46, which is formed like a tongue is, can be folded forward and accordingly also the one attached there appropriately broad clamping lock 24 support the opening movement can, as is also possible, this slot or these two slots up to approximately to be preferred in the instep area, so here again by Actuation of the two single locks 24, which have a width adjustment range go and which are correspondingly broad, the two components of the Upper shoe part 2 or a chip component 45, 46 of this upper shoe part either as already mentioned, only with the upper part of the with both parts after to be declared in front: ilpen. Through the above-mentioned attachment of the corresponding thinly formed sealing lips 14c - both on the fold-out parts as well In the area of the adjoining shaft parts, it is possible to achieve a perfect seal to achieve, since the mentioned clamping parts 45,46 in connection with the in the subsequent Stiffening inserts 7a attached to the shaft part ensure perfect dimensional stability result, so that even when the ankle joint moves, there is no gaping of the sealing lips 14c can take place and therefore both a flawless leadership and a flawless Seal is guaranteed.

In an embodiment different from FIG. 2c, it is provided in the upper part of the shoe 2 to provide a stiffening insert 5 arranged in the instep area, which is opposite the surrounding stiffening areas 7, 7a of the upper part 2 by an elastic Bellows area 20 or the like. Is separated, this stiffened instep area by means of a toggle fastener 24 in particular obliquely backwards, that is, in the direction too tight on the heel. In this case, in addition to the relief of the slip in the area above the heel, i.e. in the upper rear Tendon area, another stiffening insert can be provided, which in deviation from FIG. 2c, therefore, not in the front shaft part 3, but in the rear shaft part is arranged, so that in the rear shaft part 3 one extends over the heel area pulling down, compared to the rest of the shaft part 3 by circumferential bellows or the like. elastically movable stiffened zone 20 is provided, which in turn e.g. a tension lock, which is in the Lnochel area or the like. For example, according to the figure 2e is arranged, can be tensioned.

With this form of kissing, the instep area is applicable designed and at the same time also the rear upper shaft area that especially when the bellows area extends wider upwards between the to the lateral ankle areas adjoining stiffening areas of the shoe upper part 2 the rear, in turn stiffened shaft part 3 by pulling out the circumferential The bellows can be pulled out at an angle to the rear and thus a flawless opening and closing Slipping into the shoe is made possible.

Here, too, a single tension lock 24 is provided, which prevents the extendable rear shaft area 3 from tilting or can swim, with both a form fit in the plane as well as is provided out of the plane of the shoe upper part 2, so that after actuation of the tension lock 24, as' this was presented in connection, the entire Ski boot according to the invention without any slit, but with several elastic clamps Areas 20 is formed. In this embodiment, the shaft part 3, as is also not shown in FIG. 2c, from a lower, approximately consist of a ring-shaped circumferential part, which also includes the cap part, the instep area of the stiffening insert 45, as already mentioned, likewise is connected to the rest of the shoe upper part 2 via a circumferential bellows part 20 and wherein the upper shaft part 3 by a front arranged in the ankle joint bellows-like zones 20 together with the mentioned rear bellows part forms a joint, which essentially only in one plane perpendicular to the longitudinal axis of the shoe is movable.

In the figure 2d a partial section is shown, which through the rear area of the instalation opening, whereby it can be seen that the Stiffening insert 7a is folded over at its upper end, and e.g. with a stiffening Wire or the like. 14d is provided, in which case the upper part 3 is provided with a circumferential Groove 14a is provided, in which a corresponding reinforcement 14b of the flap-like Shaft part 3b engages, this flap part also in turn with a stiffening insert 7a can be provided.

Another embodiment is shown in FIG. 2e, wherein a cross section through the upper shaft part 3 is shown and wherein the shaft part 3 laterally has a slot 14 which is overlapped by a shaft part 12 is and this shaft part 12 again by means of a conventional lock 5 can be clamped against the adjoining shaft part and furthermore in gem Slit 14 opposite area a bending zone 20 or a bellows is arranged can be. Again, either by oblique formation of the overlapping Edges significant tension distortions are produced. There is also provision for the To provide the shaft part 3 with a pliable inner layer 36, like this already is described in connection with the figure le and if.

Werner it is possible according to FIG. 2f in the area of the shaft to provide a recess 55b into which a circumferential stiffening insert 55a is inserted and tensioned by itself, but it can also be with the outer plastic part 55 of the shaft to be connected. Here, too, there is a cushioning and sealing effect Shoe end closure 6 provided.

In the figure 2g a cross section through the shaft part 3 is shown, with the position with the tension lock 24 in the full line at clamping part 46 pressed onto the foot is shown. To make it easier to slip in, is between the shaft part 3 and the upper clamping part 46, for example a double or triple or the like. Elastic, bellows-shaped zone 20 which is further Course of the actual adapter part and the shaft part 3 connects, which with a Stiffening insert 7a, 7k are provided, and here again in particular In the area of the stiffening insert 7a, 7k, a support is formed in the aforementioned manner can be. Here again it is provided that when the ski boot is closed press the two edges of the cushion pad 29 onto one another with bias and thereby guarantee a perfect seal. With the tension lock released 24, is due to the molded-in internal prestressing that acts in the opening sense of the bellows parts 20, which are therefore to be injected into a mold, or

to be cast or otherwise manufactured - the adapter 45, 46 in held in lifted state. mr is only through the latch 24 in the actual Brought final state, so that by the elastic spreading of the two Bellows parts of the upper middle attachment part 46 is pressed forward outward, wherein As is also indicated in Figure 2c, the lower one, i.e. in the instep area located adapter 45, also with a corresponding bias to the outside can be pressed. Laterally on the elastic, bellows-shaped zones mentioned 20 in the shin-leg area closes again a substantially bow-shaped trained Stiffening insert 7a, so that there is no slit in the back of the shoe area is avoided and the shaft part 3 is relatively rigid overall can be, the stiffening insert 7a pulled up far in the shin-leg area can be and thus forms a good protection for the lower leg area does not restrict the mobility of the ankle joint.

In the figure 3 a further embodiment is shown, wherein it is intended to form the ski boot in one piece, e.g. by spraying, pouring on by means of a nozzle on a device for spraying onto the reinforcement insert how this is described in more detail, can be done. Here is the reinforcement insert 7 formed essentially in one piece, the reinforcing insert 7 in the The catfish already mentioned are coated with plastic both on the outside and on the inside or can be embedded in plastic, or it is also possible on the reinforcement insert to spray plastic by means of a compressed air spray device, so that the plastic embeds itself in the reinforcement insert, with the lining of the Shoe interior with a stiffening and / d the thermal insulation layer 15 takes place, which after at the top by a cushioning layer or by a top layer 29 can be completed.

Here, a movable one is provided in the instep area of the shoe To arrange inner part 22, which can be guided on the edges of the cushion layer 29 can, this movable inner part 22 also having a cushion layer 29 is provided, and on this inner part 22 correspondingly guided pull cables n3 attack, which attack from the outside by means of a corresponding lock 35. The access opening can already be mentioned in connection with FIG. 2e Be arranged in the rear, with the entire shaft area from a cuff 25 is enclosed, which are closed by means of a special lock can, although it is also possible to use both the tensioning device for the pulling ropes, as well as the clamping device for the circumferential cuff 25 to be confirmed at the same time.

The pull cables 33 are guided in corresponding guides 34, wherein the guide 31 of the rolster parts or the inner part 22 secure Lingsführung permitted and with the foot accordingly with the exception of the toes, which are now can move freely can be clamped in a satisfactory manner and in particular stretched back against the heel by the direction of pull of the tensioning parts 33, 34, 35 so that an ideal foot pressure is achieved, while again in the ankle area due to the design of the upper part with bending zones 20 a certain possibility of bending given is.

It has been mentioned earlier that the stiffener ate can be designed in various ways and in connection with the figures 5a to 5k are different embodiments of the stiffening insert, which are shown schematically, discussed in more detail.

According to Figure 5a, the stiffening insert is designed as expanded metal, which e.g. hexagonal, square, triangular, flat-edged, two-edged or only longitudinally slotted openings 56, which through Web 57 are connected to one another, the webs according to Figure 5b still one can experience additional bulge 58 for further stiffening and this Web can be angled upwards according to Figure 5c, so that this angled 59, despite a comparatively thin comparative thickness, a substantial stiffening of the applied or molded or overmolded plastic coating achieved wira.

Here, the expanded metal can be made of metal, however, it is also possible to use the form known as expanded metal, which is known by making slots and then deforming them, especially in spatial terms To achieve shaping in accordance with the Puss shaping, but with auh instead of one metallic, slotted or perforated structure a structure made of high melting point Plastic, crosshairs or the like. Can be used, and is known in the case of the use of crosshairs, which have a serpentine design have experienced the different areas of this reinforcement insert with different spatial recess can be formed.

However, it is also possible, according to FIG. 5i, to use a knitted fabric or a knitted fabric or a crosshair connection, e.g. as plastic threads at the crossing points 60 to twist, weld or glue together, using a thermoplastic synthetic fabric, or a synthetic knitted fabric or synthetic knitted fabric or a thermoplastic crosshair structure is achieved, because of the thermoplastic softening and the existing openings, slits etc. the shape despite a strong spatial shape, especially in the heel area and in the toe area, is easily possible, which is known, for example, with a leather shoe only with great difficulty and with the help of a winder or The like. Above all with wrinkling is possible, while when using the inventive expanded metal, mesh, fabric or the like.

a perfect deformation while adapting an originally flat one produced Gebilies to the spatial shape of the shoe in perfect Way can be achieved and with this shaping with softening or plastic Deformation takes place in the case of using a metallic expanded metal, so that after carrying out the molding process, which is a standard deep-drawing process or The pressing process is similar, the stiffening insert already receives its final shape and this stiffening insert, as already mentioned in another context was manufactured with a shape deviating from the later nominal shape, in such a way, that an externally applied preload is required for deformation and after releasing this bias, so after opening a shoe fastener the original shape, so with opened and injected shoe edges underneath the effect of the internal prestress is restored.

According to FIGS. 5d and 5e, the original planar structures can still be provided with spatial deformations in such a way that projections 61 are formed which surround the recesses 63, whereby the deformation can take place in such a way that that the projections 61 to one side and the subsequent recesses 62 are formed on the other side.

According to Figures 5f and 5g, the formation of the openings, which serve to distort the fabric by simply punching out and bending it can be achieved, the upstanding edges 65 for better adhesion of the introduced Serving plastic.

According to FIG. 5i, a soft-meshed braid or knitted fabric can also be used Find use, the shaping in a simple manner of the shaping of the mesh can be done. It is intended to use this braid e.g. in the form of metal wires or in the form of drawn-up plastic wires, but also in the form of thenoplastic Form plastic profiles, with a cross-sectional shape for better adhesion 67 for the individual threads according to FIG. 5k in a cross shape or the like can be.

However, it is also possible to use a fabric according to FIG. 5 1, which is formed with a large bond distance and wherein by use a particularly good spatial shaping possibility of thermoplastic wires in particular is achieved. It is also possible instead of the fabric technically tied execution " according to Figure 5 1 to use a pure crosshair structure, so the individual Sheets of threads are laid one on top of the other in parallel at a distance, one on top of the other or crossing over several times and where, for example, by applying these sets of threads to a shoe shape and Then the stiffening insert is sprayed on with plastic or an intermediate skin can be produced in a simple manner. In all cases, however, it is essential that the stiffening insert is spatially deformable, whereby as already mentioned, using expanded metal while distorting the original, even structure any shape can be made.

In all cases of the use of threads, wires, fabrics, crosshairs can, the already mentioned cross-sectional shape 67 using roughening, as well as threads coated with plastic or adhesive, resp. Find threads with plastic, adhesive ower the like. Use.

At this point it must be emphasized again that all described individual embodiments of the various shoe parts in any desired and can be varied and put together in an expedient manner, so that the Requests for protection on any possible combination of the individual items described above Features.

In the figure 6 is a for the production of the ski boot formation according to the invention particularly suitable method shown schematically, wherein for the production of the Sole part 1 assuming the use of strike metal, wire mesh, plastic mesh or the like. A plate 70 in the predetermined shape from a flat running Material is e.g. punched out, after which a forming punch t.B. under use a rubber counter-pad or a rigid counter-shape or the like.

a spatial deformation to an approximately tub-shaped sole part 71 takes place. Subsequent to this sole part 71 for better application of the plastic coating are provided with a thin skin 72 in the interstices so that by means of a spray gun 74, which by appropriate cam control under various Spray angles and with different spray speeds bd, 69 or with different Injection-press a skin of the same thickness in all places into the openings of the stiffening inserts is injected. A cover coating 73 is then carried out or however, it is also possible to bypass the formation by applying an external coating 73 to be sprayed on immediately, with a special for the sole part in general hard plastic is used and where a plastic injection molding process is used liquid, dissolved or heated plastic is used, which by means of corre..d Controlled nozzles 74 influenced both in width and in intensity can be una with gungsgeschwindigkiten as well as continued through various Bew different spray angles 6 ″, 69 corresponding to a previously defined layer thickness distribution a different coating thickness both according to a longitudinal profile, wit as well as after a transverse profile achieved in particular in the laterally raised parts of the sole can be. In particular, the next process step is for application a flocking, a cushioning layer, a further inner coating it is possible by different Vorlaufgeschwinvigkeit the spray nozzle and also by lateral, Controlled additional wide jet nozzles, as well as by swiveling the actual spray direction the spray nozzle 74 with a corresponding electronic punch card or the like. Control of a spatially curved sole shape according to the respective foot shape, or to achieve stiffening and / or thermal insulation layer shape. This can be done accordingly the known painting process either liquid plastic with an air jet can be applied in distributed form, but liquid plastic can also be used Injected into a fine jet split into the eyes, also with a multi-dimensional lone controlled spray nozzle 74 is used. Instead of one nozzle, several e.g. Kormen spraying nozzles 74 at different angles for use.

This one described above as well as those to be further described Shaping processes can also be used to produce other spatially shaped ones in particular Parts with different layer thicknesses can be used.

In a subsequent work step, equipment is made the hot, e.g. running parts are applied, locking parts are attached, additional parts such as leather or sotf parts can be added, flocking can also be applied, or inner layers are Inner shoes or the like. Introduced into the sole part.

The method according to the invention is suitable for this equipment, b special because both shoe parts 71,79 are open to themselves, i.e. are accessible from both sides, so that especially the cap area h the heel area, as well as the instep area e.g. in the area of the closures can be processed without difficulty.

Instead of the process of spraying, the various layers can also be applied in a dipping process, with several smoke baths one after the other 75 are run through and the order in which it is run through the immersion baths 75, which are related to the various types of plastic, dye, foam, coverings oaer the like. And can also contain in different consistencies, as well as the Bath dwell time in the course of a belt, chain or similar conveyor line by means of a PYogram control can be set. It is also possible to use the above controlled spraying and dipping or application processes in any suitable order so that, for example, one or more spray treatments following an immersion treatment can be carried out. This is particularly beneficial when layers are different Hardness or with different plasticizer content, color content, stiffening and / or Thermal insulation fiber content or layers with different curing times, different temperature decay times be applied one after the other.

This movement process for the upper part is shown schematically in FIG indicated, with the Kunststoffbesnhichtung in the previous operations by dipping 75, by more frequent dipping or by spraying on or else produced by pressing in a suitable mold, zann, after which the both shoe parts are connected to each other.

Here, by appropriate prior shaping, in particular also corrected the distribution of plastic through subsequent thermoplastic deformation or the mentioned injection stresses can be molded in, as well as the already mentioned, thinned joint parts or bellows parts are molded can.

This shaping process can also be used to create other three-dimensional Shaped parts, in particular with different layer thicknesses, are used After the mentioned complete equipping of the two shoe parts, 71, 79 in particular with an inner lining 77, with fasteners or the like Paint application in particular a different type of paint application on the two parts can be done, further impregnations can be made, the two Parts joined together in a subsequent operation, so that after joining of the two parts by gluing, welding or the like. Along the lines already described Edges of the ski boot is finished.

It is of course also possible to use the applied plastic to be colored in bulk, or different, especially translucent layers to be applied on top of one another, as is also possible, the reinforcement insert for contrast Form increase, and the rest of the outer coating 73 made of transparent plastic to be provided. As already mentioned, provision is made here to either include a single, to use the most important foot sizes and those deviating from it Smaller foot sizes due to a thicker insulation and / or padding layer to achieve, as it is also possible to insert appropriate inner shoe parts.

However, it may well be possible instead of just one to use two or three general forms and the rest of the general form Adaptation by means of appropriate training or deformation, especially afterwards Make deformation of the upholstery layers or the thermal insulation layers.

A major advantage of the manufacturing process according to the invention is that when using several and also controlled spray nozzles 74 the addition of plasticizer, hardness and foaming in the course of the Shaping or

Application process can be changed in such a way that e.g. in the cap area by adding a particularly high proportion of hardness, a particularly hard and thorough one corresponding control of the spray nozzle 74 either by increasing the pressure or by slower advance 68, 69 a particularly thick order is achieved, while e.g. by producing differently soft padding layers, e.g. in the ball area and a lower amount of foaming agent or a higher proportion in the heel area can be applied by stiffening fibers. So it is seen more precisely possible, any consistency in any area of the sole part 78 or the Schun upper part 79 to be achieved. In particular, it is in the manufacture des' shoe upper part 79 of great advantage when in the area of the bellows or the Joint area or the central opening or the corresponding elastically formed A particularly high proportion of plasticizer is added to the applied plastic in areas is, so that range of different elasticity according to the respective nozzle control can be achieved.

When applying the coating, the procedure can be that to improve the thermal insulation of the shoe to both a radiation after outside, as well as avoiding too much radiation from the outside in, a Metallization can be applied kanii, which both outside, as well as inside, or can be introduced into an intermediate layer.

It is also possible to add metal to the layers at all to be introduced or to provide metalized intermediate layers in order to provide radiation protection, thus to improve the heat balance of the ski boot according to the invention. Simultaneously karui thereby also an optical effect can be achieved by adding a high-gloss Metallization is applied, bz ;;. highlighted individual metallized lines or step on the surface of the ski boot. Finally pointed out, that the shoe formation according to the invention and the inventive method of manufacturing not only for ski boots, but also for work shoes, street shoes or the like. is suitable, as is the production method according to the invention for production other spatial structures can be used.

Regarding the question of the layer thickness control, it should be noted that through respective arrangements and aer nozzle sets 74, both in lateral and spatial Offset and with different spray angles and both the intensity of the jet, as well as by controlling successive nozzles the layer thickness in perfect condition Way is easily controllable, the control, both as a clock control, so interrupted control or by pressure-regulated control, with in the course one according to a program-controlled nozzle injection pressure more or less of the one to be applied The mass emerges from the nozzle and is only caused by air control nozzles arranged on the side, for example to correct the direction of the beam, like this for generating a broad beam Painting fixtures are already known - the intensity and distribution in simpler Way can be controlled. L15 is, for example, easily possible with bundled sheep Radiate outer sole edges in the course of the passage of the actual reinforcement insert to be applied, with the controlled In addition to their intensity control, nozzles 74 have an additional pivoting movement 68 perform, to be able to follow the additional Order in the field the sole edge or the heel a required To be able to achieve layer thickness. However, the same layer thickness control can also be used are generated by passing through cans arranged one after the other, or it is possible when carrying out the immersion process the sales area and the To dive in the shoe cap area different times and different depths, so too here again a layer thickness distribution is easily possible.

Two-part controlled or temporarily engaged Brought masking masks come to use to certain parts s.B. Holes or Like. To be able to mold without the need for a particularly difficult molding tool or injection molding tool must be used. If as reinforcement insert, fiber fleece or the like., Wire mesh or the like. Use, ksnn by appropriate choice of the injection pressure a different depth of penetration can be achieved, so that a gradual transition from a soft cushioning fiber layer, which only superficially or on individual Crossing points are glued to one another more or less completely from the outside Plastic-soaked surface is achieved so that the fiber fleece in this Palle both as a cushioning layer and as a thermal insulation layer, as well as at the same time serves as a reinforcement insert and stiffening layer. A final A completely glossy, smooth surface can be achieved by applying paint.
