Description

Extensible link strap The invention relates to an expandable link strap for jewelry and other uses, in particular a watch strap, made of two layers of sleeve members and also connecting brackets serving as spring elements, in which each link has one layer two adjacent links of the other layer is articulated by two essentially flat and rectangular in outline, interrupted on one longitudinal side connecting bracket, each of which consists of a continuous leg penetrating the sleeve member of one layer, two arranged in the longitudinal edges of the band, from the sleeve member of the a position relative to the staggered member of the other layer reaching bracket back and two inside reaching short legs is sawn from opposite sides into the same sleeve member of the other layer, and in which the connection strap upon stretching or bending of the strip against spring effect are pivotable.

These known link belts are at least in the links one layer of either leaf springs arranged from the protruding into the sleeve member short legs of the connecting bracket are tensioned when stretching the tape, for which purpose these short legs have an approximately rectangular cross-section, so that they Rotation due to the pivoting movement of the bracket when stretching the tape more space occupy between the limb wall and the end of the leaf spring, of which they are also in the unstretched State are pressed resiliently against the limb wall, or there are torsion springs used, one end of which is non-rotatably connected to one of the short legs, while the other end is held against rotation or with a diagonally opposite one the short leg of the other connecting bracket is also non-rotatably connected, so that here, too, when the belt is stretched, the tensioned springs cause a reverse torque is exerted on the bracket, whereby the tape seeks to contract again.

The invention relates to a particularly useful design of the springs and brackets which are arranged in the sleeve-shaped members of at least one layer, which results in a considerable simplification in the manufacture of the tape. Compared to the known bands of this type with leaf springs, it is with the new one Link belt possible to stretch it so far that the links of one layer between the members of the other position enter and thus almost in the same plane as these lie when the band is fully stretched. So far this has been the case with these Ribbons only possible if torsion springs were arranged in the links, e.g. B. coiled coil springs. These coil springs made of relatively thin Spring steel wire are made, but are susceptible to corrosion and tend to Waning and breaking after prolonged use, even if they are at their best Stainless steel is made because of its surface area in relation to its feather weight is very large, which creates points of attack for corrosive influences.

In a further known double-ply drawn lattice strap, the connecting brackets, which are bent from spring wire with a round cross-section, also serve as spring elements and are essentially subjected to bending. In this known drawing link belt, however, in order to enable the resilient connecting elements to be inserted, the sleeves must be specially shaped and have a central longitudinal slot with two transverse slots. The shape of this sleeve members is of course not so easy to produce such substantially tubular or box-shaped sleeve members, in which the two end faces can be left open, and this sleeve members engage the connecting bracket in g from the front side. The invention solves the problem of creating a band that is particularly extensible and as low as possible in its thickness perpendicular to the arm circumference, in which the springs are not designed as corrosion-prone helical springs, so that the disadvantage of these known springs is eliminated. Furthermore, the production of the tape and its individual parts, in particular the springs and brackets, is to be simplified and made cheaper by a new solution for the connecting brackets serving as spring elements.

In addition, as with the already known tapes, the requirement is that the tape can be disassembled at any point to provide links to be able to insert or remove.

The object is achieved according to the invention by that at least one of the legs of the connecting bracket from the parallel position is bent out to the hanging sides lying in one plane, the so bent legs between the superimposed walls of the sleeve link # held perpendicular to the stretching direction under resilient pretension and at a Pivoting movement of the bracket through the walls of the sleeve member holding it elastic can be brought into a position deviating from its starting position, in which from this Leg exerted a back torque on the bracket as a result of its natural springiness will.

A first embodiment, a self-resilient connecting bracket according to the invention it results when at least one of the two short bracket legs made in a manner known per se from spring wire with a round cross-section Connecting bracket has an extension piece, which on one side of the Level of the connecting bracket bent out and in the direction of the two short ones Bow legs opposite continuous legs of the connecting bracket bent is.

By using a round spring wire as a spring element the spring is largely protected against the effects of corrosion, so that with a break or a weakening of the pen even after prolonged use and under unfavorable conditions Conditions (high humidity, perspiration, etc.) not included needs to be züi.

If such a connecting bracket, which also represents the spring element, inserted into a sleeve member, then the free end of the extension piece is first one short leg away from the continuous leg of the connecting bracket bent back so that the spring already receives a preload as a result. because the end of the extension 01 erungsstückes outside the plane of the rest of the connecting bracket is supported on a wall of the sleeve member, the spring action generates a torque on the hanger. If now the extension piece of the short leg, its free End is held between the walls of the sleeve member by the pivoting movement the bracket is brought out of its starting position when stretching the band, then increased its spring force, and this results in an increasing when the band is stretched Back torque.

The inventive design of the bracket, the one with the spring Piece forms has considerable manufacturing advantages, which are all the more significant fall when these Bügal were manufactured in large quantities on automatic machines will. The connecting bracket including the extension piece of a short one Legs are expediently in the area of the short legs and the continuous legs The back of the stirrups connecting the legs is flattened, because these backs of the stirrups are in the The longitudinal edges of the band are visible and slide along the end faces of the sleeve links.

It has proved to be expedient, the free end of Verlängerüngsstückes of a short leg to a wire diameter of the bracket plane, so that it projects beyond the end of the opposite short leg, so that this end never pushed back into the strap plane can be 5 herauszubiegen. Furthermore, it is advantageous to make the inside width of the sleeve links containing the extension pieces, measured in the longitudinal direction of the tape, so large that it corresponds to three wire diameters, plus a margin required for movement, while the clear height of the sleeve links in both layers corresponds to only one wire diameter, so that the short legs and the continuous leg of the connecting bracket are just freely rotatable in the sleeve members of both layers.

Because the inside width of the sleeve members is only one layer is slightly larger than three wire diameters, the free end of the extension piece is located between the opposite short leg of the same connecting bracket and the diagonally opposite short leg of the second connecting bracket, the in turn has an extension piece. As a result, the free ends of the parallel to each other and diagonally through from different sides the sleeve member extending therethrough extension pieces between two each adjacent short legs safely guided.

A second and third embodiment result from the fact that the continuous leg of the connecting bracket has a flat V-shaped kink, so that the apex of this leg is outside the line connecting the Ends of this leg lies.

One possibility for constructive training is to that the continuous leg consisting of spring wire with a rectangular cross-section Like a leaf spring in the plane of the bracket V-shaped in the direction of the two short ones Leg is bent.

Appropriately, you will in this second embodiment Make whole bracket from spring wire with a rectangular cross-section and must then also bend up the short legs in the direction of the continuous leg, thus, in the contracted state of the band, the sleeve links in which the short Legs protrude, held under tension.

The other possibility is that the continuous leg from the plane of the connecting bracket V-shaped not only towards the short ones Leg bent, but also bent out to the side and with bias between the inner and outer wall of the wire diameter in its clear height corresponding sleeve member is held.

In this case, the sleeve members only need a clear height that corresponds to the wire diameter used for the bracket. The ribbon this makes it very flat. You can also do a lot with this third embodiment Easily manage the unhooking and hooking-in of the brackets if you have the sleeve members, into which the short stirrup legs protrude, with two incisions on their inner wall provides. In addition, the sleeve members can be removed from this embodiment Bend punched sheet metal pieces together, i.e. form them in one piece, because for the shortening and extension option, the above-mentioned mounting slots are sufficient. But you have to the limit possible stretching of the tape, which can easily be done thereby can that the outer walls of the sleeve members protrude beyond the temple back and with folded rag overlap and that the transverse side walls of the sleeve members at least have a position in the pivoting range of the back of the bracket cutouts through which Depth of the pivot angle of the connecting bracket is limited.

In the second and third exemplary embodiment of the inventive concept, both with the V-shaped inwardly bent bracket legs with a rectangular cross-section and with the V-shaped round bracket legs that are bent out of the bracket plane, these kinks are caused by the rotation of the continuous Legs flattened relative to the sleeve members. In the case of the flat wire bracket, the restoring force acts eccentrically to the center plane of the bracket because the rectangular bracket cross-section is supported with its diagonally opposite edges on the two opposite walls of the sleeve members. The maximum elongation of the band or rotation of the bracket legs results in this case from the fact that after the V-shaped bend has been flattened, the bracket, which is rectangular in cross section, is prevented from further rotation by the two opposite walls. In the case of the round wire bracket with a V-shaped lateral kink, the V-shape is also flattened to the extended position, which is reached after pivoting the bracket by 901 . Here, too, the natural spring force of the bracket acts eccentrically to the bracket plane and causes the reverse torque. But you have to limit the swivel angle of the bracket to less than 901 by the measure given above, because the back torque becomes zero with a swivel of 90 ' and would even be negative with a swivel movement above 901.

In order to be able to hang the connecting bracket in the first and second exemplary embodiment with their short legs in a simple manner in the sleeve members, in order to be able to dismantle the tape at any point without the use of special tools, the sleeve members expediently put themselves in a known manner in a cross-section approximately rectangular sleeves with a slot extending transversely to the stretching direction of the tape, through which the short legs of the connecting bracket can be inserted into the sleeve, and a base plate or U-rail inserted into the sleeve that covers the slot in the sleeve. The bottom plates or U-rails pushed into the sleeves of at least one link layer are expediently provided with a tongue serving as a limit stop for the pivoting movement C el of the bracket on each of the end faces. Of course, the links of the other layer can also be designed in two parts in the same way and two-part links can also be used in the third exemplary embodiment.

In a known manner, the front openings of the sleeve members and the back of the bracket can be covered by bent tabs extending from a sleeve member wall in order to round off the longitudinal edge of the band and hide the back of the bracket from view. Likewise, in a known manner, the sleeve members of the lower layer - measured in the longitudinal direction of the tape - can be kept narrower than the upper layer, so that in the contracted state of the tape there are gaps between the sleeve members of the lower layer, which prevents hair from being trapped when slipping over the tape .

Furthermore, you can in a known manner, the links of the upper layer cover with decorative shells, which at the same time also cover the sleeve link openings on the face side and can cover the back of the hanger.

The height of the back of the hanger is dimensioned in all three exemplary embodiments so that the links of the upper layer slide past the links of the lower layer when the band is stretched and can enter the gap that forms between every two links of the lower layer, so that the band in a stretched position can be brought, in which the links of the upper layer between the links of the lower layer and these are almost in one plane.

In the first embodiment according to FIGS. 1 to 10 , the link belt consists of sleeve members 10 of the upper layer and sleeve members 20 of the lower layer. As can best be seen from FIGS. 3 and 4, both the sleeve members 10 of the upper and the sleeve members 20 of the lower layer are formed in two parts, namely they consist of a sleeve 11 or 21 with an approximately rectangular cross-section and a relatively wide slot on the inside. U-rails 12 and 22, which cover the slot with their middle I-part, are inserted into these sleeves. The middle parts of the U-rails 12 pushed into the sleeves 11 of the links 10 of the upper layer have tongues 13 on their end faces which serve as limit stops for the pivoting movement of the connecting brackets.

The connecting brackets 30 (FIG. 8) consist of round spring wire and are bent together to form a rectangular bracket which has a continuous leg 31, two flattened bracket backs 32 and two short legs 33 and 34, the short leg 34 having an extension piece 35 . This extension piece 35 is so long that its free end 36 protrudes over the opposite short leg 33. The extension piece 35 is, as can best be seen from FIGS. 7 and 10 , from the plane of the connecting bracket 30 to one side bent out by about a wire diameter and also bent in the direction of the continuous limb 31 lying opposite the two short limbs 33 and 34.

The links 10 of the upper layer receive the continuous legs 31 of two connecting brackets, while the short legs 33 and 34, the latter with the extension piece 35, are received by the links 20 of the lower layer. The clear height of both the links 10 of the upper layer and the links 20 of the lower layer corresponds to the diameter of the spring wire forming the connecting bracket 30 , so that the continuous leg 31 and the short legs 33 and 34 are rotatable in the links of both La, -en are. In the installed state, the extension 35 of the short leg 34, which is bent in the direction of the continuous leg 31, is pushed back so far in the direction of the short leg 33 that the free end 36 is at the same height as the short leg 33, but next to it in the sleeve member 20 the lower layer and is resiliently supported against the middle part of the U-rail 22 pushed into this link. This position is shown in dashed lines in FIG. 8. In FIG. 10 , the free end 36 of the extension piece 35 is drawn in dashed lines in the relaxed position and denoted by 36. In the tensioned position after the connecting brackets have been inserted into the links of the lower layer, Jas free end 36 assumes the position shown in FIG. 10 and denoted by 36a. As can be seen from Fig. 7 , the two brackets, which engage with their short legs 33 and 34 and the extension pieces 35 in a sleeve member 20 of the lower layer, arranged therein alternately rotated by 180 ' , so that the extension piece 351 of one bracket from the one longitudinal band side in the direction of the other, while the extension piece 352 in turn extends from this other longitudinal band side to the former. The ends 36 of these extension pieces each lie between a short leg 33 of one bracket and the extension piece 35 of the short leg 34 of the other bracket. The clear width of the links 20 of the lower layer is approximately three wire diameters, so that the short legs 33 and 34 and the end 36 of the extension piece 35 lying between them just fill the clear width of the sleeve member. As a result, the free end 36 is guided between the two short legs 33 and 34, so it cannot leave its place when the band is stretched. In the elongation of the strip, the back 32 provide the connection bracket 30 obliquely, as shown in FIG. 2, the continuous leg 31 and the short legs 33 and 34 therefore rotate relative to the sleeve members 10 and 20. The end 36 of the extension piece 35 must, as described above, keep its place between the two short legs 33 and 34 even when the band is stretched. It thus migrates around the rotating short leg 33 , as shown in FIGS. 9 and 10 . The free end 36 of the extension piece 35 assumes the position designated by 36 b in FIG. 10 when the connecting brackets 30 have been pivoted through 900 , which corresponds to an extended position according to FIG. 6 .

Since the free end 36 of the extension piece 35 in the installed state has already been brought from the position 36 in FIG. 10 to the position 36a when the band is contracted, a spring force is effective on the connecting bracket. This spring force is expressed as a torque because the supporting force lies outside the plane of the bracket 30 . This supporting force and thus also the back-torque increased even upon stretching of the belt when the free end of the extension piece 35 is guided from the position 36 a in g C Fig. 10 in the position 36 b, as a result of pivoting of the connector bracket. The extension piece 35 on each bracket 30 ensures that the band tries to contract again and again as a result of the reverse torque acting on the bracket and that a spring force is still effective in the fully contracted state, which ensures that the sleeve members 10 of the Place the top layer tightly and resiliently against one another.

In the second embodiment according to FIGS. 11 to 17 , the stretchable link belt consists of sleeve members 40 of the upper layer and sleeve members 50 of the lower layer. As best shown in FIG. 13 , the sleeve members 40 and 50 of both layers are again formed in two parts. They each consist of a sleeve 41 or 51 with a relatively wide slot on the inside and an inserted base plate 42 or 52 . The connecting brackets 60 connecting the sleeve members 40 and 50 of the two layers are bent from spring wire with a rectangular cross section. The continuous leg 61 is bent in the plane of the bracket in a V-shape and like a leaf spring, so that its apex 64 lies outside the connecting line between the ends of this leg 61. The short legs 62 are bent open towards the buckled, continuous leg 61. The bracket backs 63 lie in the longitudinal edges of the band of the two layers of the sleeve links. Each sleeve member 40 of one layer is articulated by two such brackets according to FIG. 14 with two adjacent sleeve members 50 of the other layer. The clear height of the sleeve members 40 and 50 is dimensioned so that the apex 64 of the V-shaped bent through leg 61 and the free ends 65 of the short legs 62 on the two bottom plates 42 and 52 of the associated sleeve members 40 and 50 under tension issue. This pretensioning holds the link belt in the contracted state (cf. also FIG. 16). If the band is stretched (Fig. 12), then the continuous legs 61 and the short legs 62 rotate relative to the sleeve members, whereby the bent leg 61 is necessarily flattened in the event of unilateral force and the bent up short legs 62 are flattened as well. This unilateral spring force creates a back torque on the bracket, which tends to pull the band back together.

15 shows that at least one of the short legs 62 can also be provided with an extension piece 66 . which expediently extends beyond the middle of the bracket.

In the third embodiment according to FIGS. 18 to 24, the Hülseng C members 70 of the upper layer and 80 of the lower layer are formed in one piece, either made of drawn material or produced by bending a sheet metal blank. The outer walls 71 and 81 of the two sleeve members 70 and 80 project beyond the back lying in the tape longitudinal edges 93 of the connecting bracket 90 and extend over the back of the bracket 93 with folded flaps 72 and 82. The lateral side walls 83 of the sleeve members 80 of the lower layer have in the pivoting region of the Bracket back 93 cutouts 84, the depth of which is such that the remaining parts 85 form a limit stop for the pivoting movement of the connecting bracket 90 - . Two incisions 87 are provided in the inner wall 86 of these members for hanging and unhooking the short legs 92 of the connecting brackets that protrude into the sleeve members 80 of the lower layer.

In this third embodiment the continuous limb 91 of the connector bracket 90, as Fig. 22 best shows, bent förrnig V-out of the strap plane side, so that here too, as in the second embodiment, the apex 94 of the bent through hanger arm 91 outside the Connection line of its ends lies. In addition, this leg 91, which is bent out sideways in a V-shape, is bent slightly towards the short leg 92. The continuous sideways be buckled and bent bracket legs 91 of each pair of connecting bracket sitting together in a respective sleeve member 70 of the upper layer, whose clear height corresponding to the wire diameter of the bracket 90 used. Since the leg bent sideways is bent slightly onto the short leg, the stirrups in this sleeve member have a certain pretension. With their short legs 92 , these two brackets, which are located together in a link 70 C of the upper layer, each grip into two adjacent sleeve members 80 of the lower layer, in which they can be suspended and detached through the incisions 70. The clear height of the sleeve members 80 of the lower layer corresponds to the wire diameter of the connecting bracket, so that they can easily be rotated in these sleeves.

If the band is stretched, the continuous legs 91 rotate again in the sleeve members 70 of the upper layer due to the inclination of the bracket. Since the laterally V-shaped, kinked through legs 91 are already held with pretension in the sleeve member 70 , this kink is flattened against the inherent springiness of the bracket material, the resulting spring force acting eccentrically to the bracket plane and thereby exerting a reverse torque on the office legs, see above that also in this third embodiment, by the inherent resilience of the brackets seeks to contract back the tape. the position of the nearly straight pressed, through branch 91 in the stretched 7ustand of the tape is shown in Fig. 24.
