Multi-wall sheets (24) are arranged at a region of the structure sole and at an outsole (10) connected with the structure sole. The sheets form a connecting projection e.g. plug base, or a clamping projection or a threaded projection e.g. threaded bolt (26), which is aligned downwardly and projected from the outsole. The projections are attached on replaceable cleats (28) or spikes.

Description

The invention relates to a sports or work shoe according to the preamble of claim 1.

Such a sports or work shoe is with the subject of going back to the same inventor EP 1 097 650 B1 known. All information contained therein is also part of the present invention and is intended to be fully encompassed by the present invention.

The named EP 1 097 650 B1 relates to the development of a novel insole and its use in the manufacture of a shoe. The shell edge insole disclosed therein supports and guides the insole thereon and is characterized by having longitudinal flexibility but transverse stability. This will be according to the subject of EP 1 097 650 B1 achieved in that the shell edge insole is integrally formed from a hard, elastic plate material of uniform thickness and transverse profiles are present, which extend at least over substantially the entire forefoot area, which extends substantially over the entire foot contact area and the resilient plate material a grooved , riefen-, ribs, trough, wave, beading, meandering, meandering, zigzag or trapezoidal cross-profiling has.

In a preferred embodiment, the structural sole formed thereby consists of a spring steel material which has ribs formed obliquely to the longitudinal direction.

The shoe formed therefrom is characterized by a superior longitudinal flexibility during the rolling of the foot over a footprint, but at the same time also has the necessary for the Verkiltungssicherheit the shoe lateral stability.

However, the cited document does not describe how with the novel shell edge insole, a sports or work shoe can be made, which has from the outsole down against the footprint directed studs, spikes, protrusions and the like.

A common shoe consists of two main parts, the upper part is called shank, the lower one is called bottom. The shaft is often composed of several layers or individual parts glued or sewn together: inner shaft (lining), intermediate shaft (intermediate lining) and outer shaft (upper strap). The outer shaft can also have various spare parts, z. B. an attached rear cap around the heel area to further stabilize the foot and lead. The outer shaft is divided into different areas, in front the front sheet with the tab (tongue), in the back the lateral quarters.

Depending on the model, the floor consists of at least one sole (example: moccasin) or, as in a typical leather low shoe, an insole (insole) plus an outsole attached to it. Depending on the model between midsole even midsoles may be present, such. B. the sports shoe. Or the insole is covered by an additional cover insole or removable insole. If the outsole is not leather, it usually has a profile. The heel area often shows an increase of the shoe bottom, the heel, otherwise one speaks of a zero bottom.

Therefore, in the context of the present invention, the term "sports shoe" is understood to mean all shoes which in the broadest sense have to do with a sport, namely, for example: As running shoes, football boots, golf shoes, hiking boots, sneakers and the like.

The term "work shoe" is understood to mean all shoes that are used for work purposes, such. Safety shoes, military boots, and other work shoes.

For the purposes of the present invention, the term "insole" means the bottom part on which the foot stands on the finished shoe, unless an additional covering or insole is laid over it. The remaining shoe is grouped around the insole as a supporting element: the upper is fastened at the top and the outsole at the bottom. The assembly of the shoe takes place on the shaping strips. About him the shank is pulled (tweaked) and under him the insole provisionally attached. Then the shaft and shoe bottom are connected. The edge of the sheep lies under the insole edge. The connection can be done in many ways (so-called design): In industrial manufacturing today is the gluing (klebegezwickt) usual; more expensive shoes are also sewn (flexibly sewn, sewn or welted).

For glued shoes (AGO shoes), the insole bottom and the stick edge to be glued are first joined together and then the outsole is brushed with heat activatable adhesive and glued under the insole. In molded-on floors (for example, in sports shoes), the shaft glued to the insole or gestrobelte (attached with a zig-zag seam) is previously introduced in a mold, so that from below the Bottom can be injected and connects to the cooling with the insole and under the lower shaft edge. The profile gets the outsole by the shape in which it cools.

So far, there has always been the need to attach to the aforementioned sports or work shoes from the outsole outstanding studs, spikes or the like.

All of the types mentioned in the following description of parts buried in the rolling surface are commonly referred to as studs.

In the DE 1 888 123 A Such cleats for football boots are described in detail. They are characterized by the fact that they carry a threaded bolt on the gallery side and a threaded bushing is arranged on the side of the insole, so that the studs carrying the threaded bolt can be screwed into the threaded bushing in the insole. However, this has proven to be disadvantageous because during use dirt and dirty water can penetrate into the sole side threaded bushing and the cleaning of the threaded bushing is then extremely difficult. In addition, it is considered disadvantageous that the threaded bushing must have a certain thread length in order to ensure a stable screwing of the threaded bolt. However, this threaded bushing increases the thickness of the outsole and the adjoining insole undesirably.

Because of this, the beats DE 31 48 038 C2 that immediately creates on the outsole of the sports shoe with the outsole integrally formed downwardly projecting threaded projections on which camshells from an abrasion-resistant plastic material can be screwed. The disadvantage here, however, is that the one-piece connection of the thread projection on the outsole is difficult to accomplish and is very much stressed on shearing while running.

For this reason one has with the FR 2 070 253 A a solution was sought to reduce the shear forces on the threaded assembly between the screw-on lug into which the threaded bushing is recessed and the threaded lug at the bottom of the outsole. The named FR 2 070 253 A proposes to make this thread projection tapered to minimize the gravitational forces.

In the DE 573 693 C threaded lugs bearing lugs are connected directly via screws or other fasteners with the outsole.

The US 4,414,763 A shows that on the underside of the outsole plug-in projections are arranged, which are directed against the bottom surface and on these plug projections cleat-like parts can be plugged.

This shows also the US 4,633,600 A ,

In all of the aforementioned publications, it has already been recognized that it is disadvantageous to arrange the threaded bushing in the outsole and the cited documents show that it is more favorable to arrange the threaded bushes on the side of the replaceable lug.

The protruding from the outsole plug-in projections, jacks or threaded projections are therefore much easier to clean.

However, it has been found that the load transfer, in particular of shear loads or torque loads from the outsole is not solved on the insole, because said plug-in base or threaded projections are only integrated in the outsole. A force-transmitting connection to the insole is not provided.

The invention is therefore the object of developing a sports or work shoe of the type mentioned so that the down from the outsole outstanding plug, clamping or threaded projections ensure better load transfer with protection against shearing or loss.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that in a first embodiment, the plug-in, clamping or threaded projections are each attached individually or to several in at least one web plate and the web plate is integrated in the outsole.

In a second embodiment it is provided that the at least one web plate is arranged in the intermediate space between the outsole and the insole. In both versions, this ensures excellent load transfer from the web plate to the insole.

In a third embodiment, it is provided that the web plates completely eliminated and the brackets (threaded bolts or sockets) for the studs are mounted directly in the existing spring steel insole.

It is therefore a further development of an insole, as in the EP 1 097 650 B1 is described, which was characterized in a preferred embodiment in that it consisted of a spring steel or other flexible elastic hard material and had obliquely directed to the longitudinal axis and mutually substantially parallel conductive ribs.

According to the invention it is now provided that the web plates proposed here, which in turn firmly or interchangeably carry the plug-in, clamping or threaded projections are either firmly integrated in the outsole or are arranged in the space between the outsole and the insole that the web plates in Aligned substantially with the parallel conductive ribs of the insole and load-bearing abut against this.

Thus, now a load transfer takes place directly from the studs, which protrude from the tread and are interchangeable, on the plug, clamping or threaded projections, which are fixed or interchangeable with the web plates and from these load transfer directly to the parallel, conductive ribs the support sole. The term "support sole" here includes the term "insole". "Support sole" is understood to mean the ribbed sole made of spring steel, which is additionally encased in plastic and which forms the insole of the shoe in this assembly.

For a load-transmitting connection is created because in the power transmission between the interchangeable studs and the insole no elastomeric materials are more arranged, but an immediate load transfer to the hard support sole takes place, having parallel, conductive ribs, so that the entire load on these conductive ribs is transmitted.

In this case, it is preferred that the longitudinal axis of the web plates is aligned with the longitudinal axis of the obliquely extending ribs, so that they bear against each other in parallel and load-transmitting.

Furthermore, it is preferred if the width of the web plates corresponds approximately to the width of a rib so as to enable optimal load transfer via an optimum contact surface.

In another embodiment, however, it may also be possible to form the width of the web plates by a multiple greater than the width of the ribs, so that, for example, a web plate with two or three mutually parallel ribs is in load-transmitting connection. However, this then limits the longitudinal flexibility of the insole.

Due to the direct load transfer of digging into the ground cleats on said plug, clamping or threaded projections on the associated web plates and of these on the hard insole, it is now possible for the first time to ensure a high shearing resistance for the interchangeable studs. There is no longer the danger that the plug, clamping or threaded projections are torn out of the outsole, as was possible in the prior art.

In another embodiment of the present invention, which is also claimed as essential to the invention, it is provided that the web plates omitted and the plug, clamping or threaded projections are directly connected to the ribs of the support sole itself.

In both embodiments (connection of the plug-in, clamping or threaded projections with the web plates or with the support zone) different mounting options are provided:
A first mounting option provides a material integral formation of web plates and plug, clamping or threaded projections.

A second embodiment provides that said plug, clamping or threaded projections are welded, screwed or riveted to the web plate or the support zone.

Thus, all types of fastening are claimed, regardless of whether they are detachable or non-detachable.

The interchangeable attached to these plug, clamp or threaded projections studs have proven especially in hiking boots. A hiking boot is a special shoe that is mainly used for hiking or light mountaineering or other outdoor travel. It is often characterized by good water resistance, has a non-slip profile and is robust. Most of the shank runs from hiking boots to over the ankle. The term hiking shoe is not exactly demarcated against terms such as hiking boots or trekking shoes. The hunting boot is similar to the hiking boot from the basic principle.

Especially when hiking the feet are subject to a very high load, whether due to the soil or unfamiliar weight bearing, which is why they need additional protection so as not to fatigue prematurely or even to suffer injuries (usually in the ankle area). For this reason, hiking boots are deviating from other shoes, have a more or less firm sole and are usually over ankle high.

As soles come below the cushioning midsole rubber sole soles used because they offer the best adhesion and have a long shelf life.

According to the invention, the web plates - according to the first embodiment - are now integrated in this outsole. The integration can be done by lathering or vulcanizing or gluing. In this case, it is preferred if the web plate is received on all sides in the material of the outsole.

The same principles of interchangeable studs apply to running shoes as well. This is a special sports shoe for running. The main features of running shoes include cushioning and stabilization; H. supporting and guiding the foot during the standing and kicking phase. Furthermore, running shoes should compensate for foot deformities, such as the frequent overpronation or, more rarely, supination. In the above two types, it is particularly advantageous if you use interchangeable studs that are easily interchangeable formed according to the teachings of the present invention. This makes it possible to use on a walking shoe in flat and gently sloping terrain very soft, in the underground working cleats, while the transition to the rocky terrain other types of cleats are used, which ensures a better slip resistance on rocky terrain.

The same applies to the running shoes, in which one or more different varieties of studs are easily replaceable according to the chosen sport to the outstanding out of the outsole plug, clamp or threaded projections to attach.

Incidentally, the same applies to the application of the interchangeable studs according to the invention on so-called safety shoes. These are shoes in the form of shoes or boots, which are used as protective clothing.

They are equipped with a protective cover made of steel, aluminum, titanium or plastic in the front part of the shoe (between lining and outer shaft) to protect the toes. The upper is usually made of leather and the shoe sole is made of rubber, PU or TPU.

Again, it is essential that outstanding outsole, clamping or threaded projections are available from the outsole, are replaceable on the interchangeable studs.

The support sole according to the invention (made of plastic embedded spring steel) guarantees, among other things, a penetration safety. Such a puncture resistant sole is used in safety shoes and safety boots, as used for example in the fire department. It protects the foot against penetration injuries, through nails or other pointed objects.

The use of the web plates according to the invention for holding the plug-in, clamping or threaded projections therefore has the advantage that the penetration resistance of the sole is increased in the region of the web plates, because these web plates are arranged below the support base made of flexurally elastic, hard material and in this Area double the material thickness of the support sole.

In another embodiment of the present invention, it is provided that the inventive, from the outsole protruding plug, clamp or threaded projections on the toe cap (colloquially steel flap) are attached. The toe cap can be made of sheet steel, but also of materials such as plastic, aluminum or titanium.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other.

All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

In the following the invention will be explained in more detail with reference to drawings showing only one embodiment. Here are from the drawings and their description further features essential to the invention and advantages of the invention.

In the following description, the insole according to the invention is also referred to as a "shell edge insole" for its better characterization. However, this term is not intended to be limiting. The invention therefore relates to all embodiments which have been mentioned in the general description part.

• (1) eine Stützsohle 2, deren seitliche Begrenzung 3 (Stützsohlenbegrenzung) zumindest im Vorderfußbereich, gegebenenfalls auch im Mittel- und/oder Rückfußbereich, dem eigentlichen Brandsohlenumriss (d. h. dem von einer Brandsohle eigentlich einzunehmenden Umriss) entspricht;
• (2) einen nach oben zu verlaufenden schalenförmigen Rand 4 (Schalenrand), der insbesondere folgende Merkmale hat: (a) der Schalenrand 4 ist zumindest im Vorderfußbereich vorgesehen, er kann jedoch auch im Mittel- und Rückfußbereich vorgesehen sein, wobei er in diesen Bereichen nach oben verlaufen kann oder sogar flach sein könnte, (b) der Schalenrand 4 erstreckt sich, wie die 1, 2 und 3 deutlich zeigen, seitlich über die Stützsohlenbegrenzung 3 hinaus, (c) der Schalenrand 4 ist fest mit der Stützsohle 2 verbunden, und (d) der Schalenrand 4 besteht aus einem gegenüber dem relativ harten Stützsohlenmaterial weichem, flexiblem Material;
• (3) die Schalenrandbrandsohle 1 besitzt weiterhin eine Verdickung 5 auf der Unterseite der Stützsohle 2, welche insbesondere folgende Merkmale hat: (a) die Verdickung 5 ist zumindest im Vorderfußknochenbereich vorgesehen, wo sie die Auftrittsfläche des Fußes abstützt, sie kann auch darüber hinaus im Mittel- und/oder Rückfußbereich, insbesondere im Fußknochenbereich des Mittel- und/oder Rückfußes, vorhanden sein. (b) die seitliche Begrenzung 6 (Verdickungsbegrenzung) ist bezüglich der Stützsohlenbegrenzung 3 sohleneinwärts so weit versetzt, dass auf der Brandsohlenunterseite zwischen der Stützsohlenbegrenzung 3 und der Verdickungsbegrenzung 6 eine Zwickeinschlagsausnehmung 7 gebildet ist, in die, wie die 3 zeigt, das Schuhobermaterial 8 im Bereich des Zwickeinschlags eingefügt und dort sowie im Außenbereich des Schalenrands 4 an der Schalenrandbrandsohle festgeklebt wird, wobei die Verdickung 5 normalerweise die gleiche Dicke wie das Schuhobermaterial 8 im Bereich des Zwickeinschlags hat, so dass der Zwickeinschlag 9 zusammen mit der Verdickung 5 eine praktisch ebene Unterseite bilden, an die eine Laufsohle 10 (siehe 3) vollflächig angeklebt werden kann;
• und (4) außerdem sind Mittel zur Querversteifung und/oder Längsflexibilisierung der Stützsohle 2 und/oder der Verdickung 6, zumindest im Vorderfußbereich, gegebenenfalls auch im Mittel- und/oder Rückfußbereich, vorgesehen. Die Mittel zur Querversteifung und/oder Längsflexibilisierung der Stützsohle und/oder der Verdickung sind in den 2 und 6 eine Struktursohle 11, die beispielsweise aus querprofiliertem Federstahl besteht und sich im Bereich der Stützsohle 2 erstreckt, wobei diese Struktursohle 11 durch flexible Materialien 12 und 13 eingebettet ist, so dass die Stützsohle 2 eine ebene obere und untere Oberfläche hat, die unten vollflächig in die Verdickung 5 und seitlich nahtlos in den Schalenrand 4 übergehen kann.

The in the 1 and 2 the drawing in total with 1 designated shell edge insole comprises the following individual elements:

• (1) a support sole 2 whose lateral boundary 3 (Support sole limitation) at least in the forefoot area, possibly also in the middle and / or hindfoot area, corresponds to the actual insole outline (ie the outline actually to be taken by an insole);
• (2) an upwardly extending cup-shaped edge 4 (Shell edge), which in particular has the following features: (a) the shell edge 4 is provided at least in the forefoot area, but it may also be provided in the middle and hindfoot area, where it may extend upwards in these areas or even be flat, (b) the shell edge 4 extends like the 1 . 2 and 3 clearly show, laterally over the support sole boundary 3 addition, (c) the shell edge 4 is firm with the support sole 2 connected, and (d) the shell edge 4 consists of a flexible material that is soft with respect to the relatively hard backing sole material;
• (3) the shell edge insole 1 still has a thickening 5 on the bottom of the support sole 2 which in particular has the following characteristics: (a) the thickening 5 is at least provided in the forefoot bone area, where it supports the tread surface of the foot, it may also be present in the middle and / or hindfoot area, especially in the foot bone area of the middle and / or hind foot. (b) the lateral boundary 6 (Thickening limit) is with respect to the support sole boundary 3 offset so far inward that on the insole bottom between the support sole boundary 3 and the thickening limit 6 a Zwickeinschlagsausnehmung 7 is formed in, like, the 3 shows the shoe upper 8th inserted in the area of the perimeter fence and there and in the outer area of the shell edge 4 is glued to the shell edge insole, the thickening 5 usually the same thickness as the shoe upper 8th in the area of the perseverance, so that the twill impact 9 along with the thickening 5 form a practically flat bottom, to which an outsole 10 (please refer 3 ) can be glued over the entire surface;
• and (4) also means for transverse stiffening and / or longitudinal flexibilization of the support sole 2 and / or thickening 6 , at least in the forefoot, possibly also in the middle and / or hindfoot area, provided. The means for transverse stiffening and / or longitudinal flexibilization of the support sole and / or the thickening are in the 2 and 6 a structural sole 11 , which consists for example of cross-profiled spring steel and in the area of the support sole 2 extends, this structural sole 11 through flexible materials 12 and 13 is embedded, so that the supporting sole 2 has a flat upper and lower surface, the entire bottom in the thickening 5 and laterally seamless in the shell edge 4 can go over.

What the other preferred features of the structural sole 11 In this regard, reference is made in this regard to the comments above in the general part of the description.

Another essential agent with which the thickening 5 can be made longitudinally flexible and stable, is off 1 can be seen, after which incisions in the thickening 14 are provided transversely to the insole longitudinal direction, through the entire thickness of the thickening 5 or only through a part of this thickness and the thickening of a ladder-like structure, such as 1 shows very clearly, give.

The already explained in more detail above angle a and y, under which the transverse stiffening means, such as the ladder-like ribs 15 between the incisions 14 the thickening 5 and / or the mountains 16 and valleys 17 the wavy structural sole 11 , Preferably, and which are synonymous with the direction of the maximum transverse reinforcement, and the angles β and 6 The maximum longitudinal flexibility, which normally runs perpendicular to the maximum transverse reinforcement, is in 1 drawn for clarity, with the longitudinal axis of the sole with 18 is designated.

Also, in 1 Notches or wedge-shaped cuts 19 to see that in the shell edge 4 are provided in the region of the predetermined bend, in particular of the bale, in order to produce a web effect (resistance to the intended bend) and / or a swelling (bowing) of the shell edge 4 to prevent.

Finally, in 2 an insole adapted to the shoe to the foot of the wearer 20 shown, which fit into the top of the shell edge insole 1 can be inserted so that it is held secure against deformation by the shell shape and the stability of the shell edge insole according to the invention deformation-proof and guarantees a highly stable adaptation to the foot.

It is a shell edge insole that supports the foot, forms the basis for a full-width system, the thickening in the ball mass 5 has, preferably with ladder-like transverse ribs, which ensures lateral stability.

The shell edge insole 1 includes a floor 2 . 5 and a side shell edge 4 , The side shell edge 4 has a preferred height h of 3.5-8 mm in the front of the forefoot and 0 to 18 mm in the back of the hindfoot to accommodate different insoles 20 with which different feet and foot thicknesses (multi-span system) are absorbed. Thickness of thickening 5 is preferably between 1.0 to 3.0 mm, and the thickness s of the support sole 2 is preferably 1.0 to 5.0 mm.

The advantage of the shell edge insole 1 consists in particular that can be absorbed by a shoe different foot sizes and foot thicknesses at the same foot length; the different volumes of the feet are provided by different insoles 20 collected.

The thickening 5 is preferably made of a compacted, thickened material. To ensure lateral stability and penetration resistance, but not to hinder flexibility, is the thickening 5 the thickened shell edge insole, preferably ladder-like with the transverse cuts 14 between the ribs 15 Mistake. The direction of the transverse incisions is oriented along the line of the stress processes and is preferably 77 "to the longitudinal axis in the forefoot region in adults, in the rear foot region 103".

Depending on the size of the shoe and the age of the child, these angles may vary. The sum of the transverse grooves preferably always results in 180 ". For example, for the toddler a transverse groove in the forefoot area of 90 "and in the rearfoot area of 90" makes sense, for sizes 30 to 32 an angle of 86 "in the forefoot area and 94" in the hindfoot area, for the size 33 to 35 an angle from 81 '' in the forefoot and 99 '' in the rear foot area, for the shoe sizes from 36 the adult form 77 '' and 103 ''. The advantage of these different angles is that the sole adapts to the level of development of the foot to support the development of the child's foot from the square foot to the (slender) adult foot.

The thickening 5 the bottom part of the shell edge insole 1 intercepts all major stress zones of the foot in all phases of the stress process. The thickening is sufficient 5 of the soil 2 . 5 the shell edge insole 1 not up to the edge of the insole contour, but is so far from the inside that enough space 7 and material for a perseverance 9 and for bonding the shoe upper 8th consists.

To avoid a web effect, can also on the upper side in the shell edge 4 the peel edge insole scores 14 introduced the flexibility of the shell edge insole 1 increase.

The cupped insole 1 has wearing properties and is thus defined differently to normal insoles. It is the defining element of the shoe. The shell edge insole 1 supports and guides, the insole thereon 20 dampens and guarantees a pleasant foot climate, in particular through a Wasseraufsaugekapazität.

The shell edge insole preferably has a high Shore hardness, with the exception of the soft shell edge, in particular a high Shore A hardness or Shore D hardness, preferably a Shore A hardness of 80 to 100 or a Shore D hardness of 70 to 100. This is especially true for the thickening, if this has a ladder-like structure. In order to ensure the flexibility of the shell edge insole, on the one hand the Bo-the - ladder like notched or otherwise made longitudinally flexible, preferably the shell edge in the range of Sollbiegekurven (bale) is notched to no web effect or raising the shell edge to enable.

The adhesive surface of the thickening of the shell edge insole (corresponding to the ball mass) should be as plane as possible flat.

The shell edge insole consists of a one-piece or multi-piece material, which has a shell edge shape whose shell edge adapts to the outer foot shape. The bottom of the tray can accommodate an insole of varying thickness to accommodate varying widths and has a tray base that protrudes from the tray sole contour to support the main load zones in foot movement, thus supporting the foot and providing enough lateral surface to provide a shaft to pinch or stick, and leads the foot. The insole guarantees cushioning in the hindfoot area and bedding in the forefoot area.

Out 1 that results in the structural sole 11 incorporated conductive ribs 15 a width 35 while the space between the ribs has a width 36 having.

The space between the ribs is also as an act 17 denotes and prefers to the bottom of the structural sole 11 ie, for example, except for the spring steel material.

It is important now that aligned and in line with the conductive ribs 15 in the 2 shown web plates 24 arranged load-transmitting, which consequently at the bottom of the ribs 15 load-bearing abut.

Each web plate 24 is preferably made of a metal material or a hard plastic material, which has the properties of a metal material in terms of its bending stiffness and strength and in the embodiment shown are in the web plate 24 a series of recesses arranged in which threaded bolts 26 are admitted. These threaded bolts 26 protrude with their bolt ends 27 through the outsole 10 through, as is in 2 is shown. The width of the web plates 24 is chosen so that they are at the limits 23 stops, so they each in a recess 22 lies flush, which through the front sides of the shoe upper 8th is formed. The recess 22 is usually filled by a ball mass and polished smooth, so that there is a perfectly flat bottom, to which the outsole 10 is glued.

The web plate 24 is perfect in the material of the outsole 10 integrated. This can be done by inserting the web plates into the foaming or casting mold during production of the outsole in a foaming mold and then foaming the mold.

The integration in the outsole 10 has the further advantage that the length of the web plates 24 almost to the outer edge of the outsole 10 can extend so that the spikes or studs can be placed completely outside the outsole, which improves the slip resistance of the shoe and counteracts a tendency to roll.

Surefootedness is also improved by the fact that the outsole-side fasteners (sockets or threaded bolts) require only a small overall length and thus the insole and the outsole 10 can be made very thin. This avoids an undesirably high shoe structure.

In 2 are the web plates 24 However, only shown with shortened length, which was only for the sake of clarity.

Out 2 it can be seen that the structural sole 11 with the flexible material 12 . 13 is filled to give a flat surface on which the thickening 5 is formed.

On the bolt ends 27 can now the in 2 lower illustrated studs 28 be screwed on, with each stud a threaded bushing 30 has and an upper Schraubrand 32 which can also be designed as a hexagon or the like. The tunnel 28 is preferably made of an elastomeric material 31 , However, it may also consist of a metal material or a metal-plastic composite material.

With the arrangement of threaded bolts 26 working in multi-wall sheets 24 are attached and their bolt ends 27 through the outsole 10 projecting downwards in the direction of the footprint, the advantage is achieved that dirt in the area of the bolt ends 27 easy to remove. The dirt-prone threaded bushings 30 are located in the area of the tunnels 28 , causing the studs 28 with contamination of the threaded bush 30 can be easily exchanged.

Advantage is that the thickness of the web plate 24 is very low and therefore a very low height of the entire structure of the shoe, consisting of the insole 20 , the structural sole 11 , the flexible materials 12 . 13 , the thickening 5 and the outsole 10 is given, which was not possible in the prior art.

In the prior art had the threaded bushes 30 in the area of the support sole 2 be installed or even just in the area of the outsole 10 , which accordingly had to be increased in thickness. This was unfavorable in the sense of lowering the center of gravity of the user in the direction of the footprint of the shoe.

The 3 shows as a plan view of the outsole, as the relatively narrow web plates 24 parallel to the conductive ribs 15 the structural sole 11 extend and preferably with the width of the conductive ribs 15 coincide and abut against this load transfer.

As a result, the width is equal 37 the respective web plate 25 the width 35 the conductive ribs 15 ,

However, it may be provided in another embodiment that the width 37 the web plates 24 is twice as large and, for example, two ribs 15 in 1 covered and frictionally applied to these.

As a result, the longitudinal axis also coincides 40 the web plates 24 with the longitudinal axis 38 the respective rib 15 ,

In 3 It is shown that other web plate shapes may be used in the heel area. The web plate shown there 25 is approximately triangular in shape and thus takes z. B. at different locations the screw, plug or terminal sockets for three different studs 28 . 29 on.

In 4 is shown as an embodiment jack. There it can be seen that on the web plate 24 socket 33 are arranged on which associated mounds 29 can be plugged.

It is not shown for reasons of simplification that such jack can still be secured by additional clamping or torsion.

The 5 shows as a further embodiment that the web plate 24 Material integral with bolt ends 27 connected or that the bolt ends 27 by welding or other permanent fasteners with the web plate 24 are connected. It will be about triangular screw studs 28 with internal threaded bushings 30 on the bolt ends 27 screwed.

In the drawings, for reasons of simplification, it is not shown that instead of the threaded studs 28 or the mounds 29 also clamping studs can be present, the z. B. work on the bayonet principle. Again, it is important that the clamping part (clamping base) through the surface of the outsole 10 protrudes downwards in the direction of the contact surfaces and that the clamping receptacle is arranged in the tunnel itself.

The 6 and 7 show the ripple structure 21 the structural sole 11 , which in the embodiment according to 6 and 7 consists of a corrugated spring steel material.

Between the mountains 16 Trained corrugated structures are corresponding valleys 17 educated and every mountain 16 thus forms the conductive ribs 15 on whose surface the web plate 24 load-transmitting applied.

As a result, the width is equal 39 the corrugation of the supporting sole 11 about the width of the respectively there load-transmitting adjacent web plate 24 ,

It has already been noted that the width 37 the respective web plate 24 can be chosen larger, so that z. B. two ribs 15 in 6 engages and abuts there load-transmitting.

By this load-transferring system it comes - in contrast to the embodiment according to 2 where flexible material 13 the rippled structure 21 fills, to a direct, load-transferring and metallic system between the top of the web plates 24 and the underside of the corrugated structure 21 formed by the conductive ribs 15 , In this way, tilting moments and shearing forces become effective from the corrugated structure 21 the structural sole 11 taken and effectively initiated into the chassis of the shoe.

In the drawing 7 is shown that the threaded bolts 26 (or the not shown socket 33 ) also directly in the corrugated structure 21 the structural sole 11 can be attached. Of course, the same applies to the terminal block, which are opposed by the clamping lugs not shown in detail in the drawing. It is possible for all previously described embodiments to combine the different types of fastening (threaded fastener, clamp attachment and plug-in mounting) with each other. So it can be provided in the ball area of the shell insole 1 the thread fixing of studs 28 provided, while in the heel area the plug fastening of the studs 29 given is. Accordingly, all combinations of the fastening systems described above are possible with one another on a shell insole.

In 8th is another shape of a web plate 24a shown. It has meandering edge boundaries, which ensures good flexibility with low weight.

In the 9 illustrated web plate 24b has a double club shape. Fasteners for bolt ends 27 or the socket 33 are in the arranged widened end portions which are interconnected by a narrow web.
