Abstract

A ski binding comprises a front jaw, a heel grip and a connecting element extending in the longitudinal direction of the ski between the front jaw and the heel grip. The heel grip is arranged at the rear end of the connecting element and is slidingly guided in a guide rail secured to the ski. When the ski binding is assembled, the front jaw is fastened, together with its support, directly on the upper surface of the ski. To permit the ski to flex freely when traversing depressions with boots of all sizes, the connecting element (3) extends unguided between the front jaw (4) and the heel grip (5), the front jaw (4) has a locking element (8) to which the connecting element (3) can be fixed by means of a seat (1) in the longitudinal direction of the ski, and the heel grip (5) can be adjusted and locked relative to the connecting element (3) in the longitudinal direction of the ski.

Description

Ski binding

The invention relates to ski bindings according to the preambles of claims 1 and 3.

A ski binding according to the preamble of claim 1 is described in DE-OS 1 478 106 (see FIG. 2) (cf. also the prospectus from 1965/66). With this ski binding, the stiffening of the ski occurs in the area under the ski binding as a result of the plate supporting the front jaws, which hinders flexing of the ski when driving through troughs, particularly in the case of small boot sizes.

In the ski binding according to US Pat. No. 3,937,481, a metal band is slidably mounted on the ski and secured against lifting off the ski. The metal band carries a front jaw and a heel holder, the latter being adjustable in relation to the metal band to adapt to different shoe sizes. The metal band itself is guided in the longitudinal direction of the ski by a screw engaging in an elongated hole and two lateral claws. At the front end of the metal band is cut a kind of rack, with which a worm meshes, which is housed in a ski-proof housing and is loaded by a compression spring. The purpose of this ski binding is, on the one hand, to allow the ski to bend when passing through depressions and, on the other hand, to dampen a shock which is exerted on the skier and which occurs when the ski hits an obstacle. The manufacture of this ski binding is difficult.

Finally, US Pat. No. 3,314,687 describes a ski binding in which a continuous profiled guide rail is fastened on the ski below the toe piece and the heel holder. By means of this guide rail, however, such a stiffening of the ski in the area under the ski binding is brought about that, in this area, bending of the ski is practically excluded when passing through a depression.

The object of the invention is to eliminate the disadvantages of the known bindings and to provide two solutions which enable the ski to bend freely in all shoe sizes. Starting from a ski binding according to the preamble of claim 1, this object is achieved according to the invention by the combination of the three features specified in the characterizing part of this claim. This combination enables the ski binding to be set up easily.

Of these three features, the second is known from DE-OS 3109 754. In the described embodiment, however, it is disadvantageous that the front jaw is not attached directly to the ski, but rather can be fixed in various positions via a guide rail in which a row of holes is left open. A locking screw is provided for this purpose. The metal band extends above the guide rail, so that to adjust the front jaw relative to the metal band, the locking screw must be loosened and the entire front jaw including the metal band must be pushed out of the guide rail.

As far as the third feature is concerned, this can be found in the aforementioned US Pat. No. 3,937481. Here too, as has already been stated, the heel holder can be adjusted and operated in different positions relative to the metal strap in the longitudinal direction of the ski. The toe and heel holder can be adjusted relative to the ski using the metal band for different driving styles. Another embodiment in which the heel holder is adjustable relative to the metal band can be found in FIGS. 3 and 4 of DE-OS 22 22 161. In this version, the metal band is firmly connected to the base plates of the toe and heel holder. However, the heel holder is not arranged on the metal band and is not slidably guided in its guide rail. However, this does not achieve the desired elasticity of the ski when the ski binding is installed.

The measure of claim 2 has the advantage that practically all structural elements are already present in commercially available front jaws, and that only one element, namely the support body, must be provided with a projection. Claim 3 is based in its preamble on the already discussed DE-OS 3 109 75 ^. Compared to the known construction, in which the connecting element between the front bar and the heel holder is passed under a slide plate attached to the ski and in which the front jaw has to be pulled out of the guide for adjustment, the solution according to the invention has the additional advantage that the Adjustment of the toe piece to different shoe sizes can be done very easily without pulling out the toe piece.

The features of claim 4 enable reliable shielding of the connecting element against moisture and dirt in all ski boot sizes. Compared to * a product on the market, which is described, for example, in ESS-VAR Catalog 87, the features of claim 4 have the advantage that no individual adaptation of the cover to different ski shoe sizes is required. However, this eliminates the need to cut off individual areas in the case of small ski boots and to replace the cover if the same binding is to be switched from smaller ski boots to larger ski boots. Furthermore, the connecting element, which is designed as a metal strip, can also be produced from a non-stainless steel.

The subject matter of claim 5 ensures, in a structurally particularly simple manner, the adaptation of the connecting element to ski boots of different sizes.

For the structural design of the latching, the features of claim 6 indicate a particularly cheap and simple solution.

The solution specified in claim 7 has the advantage that the connecting element can be continuously adjusted relative to the guide rail for the toe piece. The construction according to claim 8 has proven to be particularly advantageous, especially since no additional elements have to be used for this adjustment. The subject matter of claim 9 enables reliable guidance of the connecting element in the area of the heel holder in a simple manner.

Due to the measure of claim 10, the manufacture of the locking element for the adjustable heel holder is carried out in a particularly simple manner, regardless of the choice of material for the compounding element. In addition, this measure enables the use of a greater material thickness for the approach receiving the locking teeth than would be possible with the connecting element for reasons of its flexibility.

By the measure of claim 11, the end regions of the connecting element which are exposed from the casing are also protected. Furthermore, the assembly and disassembly of the ski binding is made easier. The features of claims 12 and 13 also aim constructively in this direction.

The features of claim 14 ensure easy locking of the tread plate and cover.

The measure of claim 15 has the advantage that an erroneous placement of a hole with a circular cross section on the square projection is excluded.

Although the adjustment range of the heel holder relative to the connecting element makes it possible to adapt the ski binding to ski boots of different sizes to a predetermined extent, this adjustment range is increased by the subject matter of claim 16. The measure of claim 17 also aims in this direction.

The feature of claim 18 enables multiple use of the same connecting element, since this can also be used in connection with a toe piece or with a guide rail of an toe piece in accordance with claims 1 to 14 without any change.

Due to the features of claim 19, material is saved on the one hand and on the other hand the curvature of the ski caused by the two clamping jaws (front jaws and heel holder) is displaced upwards by shifting the rear attacking boot tes the sole of the shoe slightly better compensated towards the center of the binding. This also improves the pressure distribution on the ski.

The measure of claim 20 has the advantage that the friction between the ski boot and the pedal is reduced.

Due to the subject matter of claim 21, the pressure transfer from the pedal to the ski takes place over the end faces of the projections, that is to say flat and not linear as in the case of a roller.

If a connecting element with a sheathing is used, the measure of claim 22 can be used with advantage.

Due to the subject matter of claim 23, the connecting element itself is used for pressure transmission. The possible arrangement of at least one support enables height compensation and brings about a reduction in wear on the connecting element.

The subject matter of claim 24 results in a damping of the impacts that occur on the skier during the journey.

The measure of claim 25 has the advantage that the elastic layer cannot be damaged by the ski boot.

The features of claim 26 enable a particularly simple production of the elastic layer. The subject matter of claim 28 also aims in this direction.

The measure of claim 27 saves material. The connection of the casing and layer specified in claim 29 has proven to be particularly advantageous.

The subject matter of claim 30 enables a subsequent application of the elastic layer in the case of an already existing ski binding.

The measure of claim 31 makes it possible to adapt the elastic layer to the weight of the skier and his driving style. This goal is also reflected in the characteristics of the Claim 32 sought.

The subject matter of claim 33 reliably prevents the casing from being unintentionally detached from the connecting element.

The measure of claim 34 makes it possible for the elastic layer to lie flat on the underside of the connecting element, with a perfect connection to the casing nevertheless being produced.

The features of claim 35 make it possible to use a ski brake according to claims 19-21 even without a connecting element. The subjects of claims 36 and 37 also aim in this direction.

1 and 2, the ski binding is designated by 1 in its entirety. This is attached to a ski 2. The ski binding 1 comprises a connecting element designed as a metal band, a toe piece 4 which is connected to the metal band 3 in a manner to be described in more detail below, a heel holder 5> which is guided in a ski-fixed guide rail 13 and can be locked in different positions with the metal band 3, and a ski brake 25.

In the front jaw 4, an angular supporting body 4a is arranged, whose one limb 4a ₁ is perpendicular to the ski top face and the other leg parallel to the ski top face 4a ₂ verläuft.Der legs 4a _2, as Figure 4 shows, fixed to the ski 2 by means of screws 12th 3 is connected to a housing 7, which receives a release spring, not shown, in a known manner. The horizontal leg 4a ₂ carries a projection 8 which projects downwards. 6, the adjusting screw for the release spring is designated.

The metal strip 3 extends in the longitudinal direction of the ski 2. At its front end there is a row of 3 in the metal strip Cut out holes 9. In one of the holes 9 of the row of holes is on the leg

4a _{2 of} the support body 4a arranged projection 8 snapped. At the rear end of the metal strip 3, a shoulder 10 is fastened by means of rivets 11 on the upper side thereof under the heel holder 5. In the extension 10, two rows of rectangular locking recesses 10a are punched out, into which locking teeth 5b of an adjustment locking 5ades heel holder 5 engage in a manner known per se. The metal band 3 is somewhat widened in the area in front of the heel holder 5 (see FIG. 7). In this area, two elongated holes 3a running in the longitudinal direction of the metal strip 3 are cut out, which are penetrated by fastening screws 12 for the guide rail 13 in which the heel holder 5 is guided.

Between the front jaw 4 and the heel holder 5, the metal band 3 is provided with a casing 14 made of a plastic material. In its front area, the metal strip 3 is also provided with a tread plate 15 and in its rear area with a cover 16. Tread plate 15 and cover 16 can be moved in the longitudinal direction of the ski 2. For this reason, the two cover elements 15 and 16 - seen in cross section - are approximately U-shaped, the two legs carrying inwardly directed flanges which engage under the metal strip 3 or its casing 14 (see in particular FIGS. 5 and 8 ). 3b designates two lateral recesses in the metal strip 3, which are subsequently cut out to the casing 14 in the direction of the front jaw 4. 14a denotes two lateral tapering in the casing 14, which are provided in the section of the casing 14 facing the heel holder 5. The lateral recesses 3b of the metal strip 3 and the tapering 14a of the casing 14 serve to facilitate the mounting and removal of the tread plate 15. Furthermore, the tapering 14a also serve to facilitate the assembly and disassembly of the cover 16.

Both the tread plate 15 and the cover 16 have a resilient tongue 15a or 16a which, in the mounted position, locks the associated cover element (15 or 16) on a ski-binding part which is fixed to the ski.

If the distance between the front jaw 4 and the heel holder 5 is to be changed to adapt to differently sized ski boots, the leg 4a _{2 of} the support body 4a is first unscrewed from the ski 2. Then the metal strip 3 can be separated from the projection and then

8 / be moved until the desired distance between the front jaw 4 and the heel holder 5 is reached. The projection 8 snaps into the desired hole 9 in the row of holes. After this shift, the leg 4a ₂ is screwed back on. This setting is a rough setting in view of the relatively large removal of the holes 9 of the row of holes.

For the fine adjustment of the distance between the front jaw 4 and the heel holder 5, the adjustment catch 5a of the heel holder 5 with respect to the guide rail 13 is first released, then the heel holder 5 is brought into the desired position in the guide rail 13 and locked in place again. The distance between the recesses 10a is so dimensioned so that a proper hold of the ski boot, not shown, between toe 4 and heel holder 5 is guaranteed.

The second embodiment of a ski binding shown in FIGS. 9-10a differs from the one described first in that the front jaw 4 'is not attached directly to the ski 2', but in that a guide rail 20 is attached to the ski 2 'in which the Front jaws 4 'can be adjusted. The heel holder (not shown here) corresponds to the embodiment according to FIG. 6. Behind the front jaw 4 ', the guide rail 20 carries a rotatably mounted pin 21 which projects vertically upwards, the head 21a of which is elongated in plan view and provided with a screw slot 21b. In the metal strip 3 ', at the front end, a plurality of holes 22 which are oblong in plan view and which allow the head 21a of the bolt 21 to pass through are punched out. The longitudinal axes of the elongated holes 22 run transversely to the longitudinal axis of the metal strip 3 '.

The distance of the guide rail 20 from the top of the ski 2 'is determined by three feet 20b, which serve to receive fastening screws 12'. Of these feet 20b, a pair lies symmetrically to the vertical longitudinal center plane of the guide rail 20. The third foot 20b is offset away from this pair towards the front end of the guide rail 20 and lies together with one foot of this pair in a plane parallel to the vertical longitudinal central plane of the guide rail 20. This foot 20b with respect to the vertical longitudinal median plane, the locking device for the front jaw 4 'is arranged.

The underside of the head 21a of the bolt 21 is provided with at least one projection 21c, which in ei ne recess on the circumference of the hole 22 engages when the longitudinal axis of the head 21a is perpendicular to the longitudinal axis of the hole 22.

If the metal strip 3 'is to be adjusted relative to the guide rail 20, the bolt 21 is first turned by 90 ° with the aid of a screwdriver, so. that his head 21a is aligned with the hole 22. The end region of the metal strip 3 'can then be lifted off the bolt 21. Now the metal band 3 'is set to the desired distance of the heel holder 5 from the front jaw 4', and then the selected hole 22 is placed on the bolt 21. Then the bolt 21 is rotated again by 90 ° and held in this position by the projection 21c. The latching effect can be further enhanced by the fact that a plate spring is placed on the bolt 21 under the guide rail 20, which tries to pull the bolt head 21a downwards. Now the entire ski binding can be set to the desired ski boot size and mounted on the ski.

The embodiment of a ski binding according to FIGS. 11-13 differs from the ones described above in that the metal band 3 "also in the area of the

Front cheek 4 "rests directly on the top of the ski 2". The guide rail 20 'has at its rear end a cranked section 20' a which presses the metal band 3 "against the ski 2" when the fastening screws 12 "are tightened. The guide rail 20 'is fastened as in the exemplary embodiment according to FIGS. 9-10a, namely by three feet 20'b, which serve to receive the fastening screws 12 "and a pair of which is arranged on both sides of the vertical longitudinal center plane of the guide rail 20 '. At this In a variant, the metal strip 3 ″ can also be firmly anchored on or in the guide rail 20 ′. This embodiment, which is also according to the invention, has the advantage of faster assembly.

According to FIGS. 14 and 15, the front jaw 4 has a housing 37 which is screwed onto the ski 2 and which carries at its base 37a a downward projection 38 formed as a square. In the connecting element 3, in addition to circular-cylindrical holes 39a, a hole 39b with a square cross section is also cut out at its front end. The projection 38 arranged on the housing 37 of the front jaw 4 engages in this hole 39h without play. However, if the hole 39b is of a different, non-circular cross-section, e.g. one in the form of a K-profile, the projection 38 is adapted to this cross section.

As can be seen from FIG. 15, the hole 39b with the square cross-section is arranged in the central region of the row of holes with the circular cylindrical holes 39a. If the circumference of a circular cylindrical hole 39a is projected onto the square hole 39h, its side walls touch the circumference of the hole 39a. This ensures a play-free insertion of a cylindrical pin from another front jaw into the square hole 39b.

The variant of a connecting element 3 'shown in FIG. 15a is characterized in that instead of a single hole 39h according to FIGS. 14 and 15 with a square cross section, two such holes 39'b are left in the connecting element 3', which are arranged one behind the other in the longitudinal direction of the ski are arranged. As a result, the connecting element 3 'can be fixed in two different positions relative to the front jaw 4. However, it is also possible to arrange the two holes with a square cross section at a distance from one another, with at least one circular-cylindrical hole being located between these holes. In this way, the ski binding can be adapted to different groups of shoe sizes. The embodiment of the front jaw 4 'of a ski binding shown in FIGS. 16 and 17 is characterized in that its housing 37' is not fixed directly on the top of the ski 2, but in a guide rail 311 which is attached to the ski 2 by screws 312 is attached, adjustable and lockable. To fix the housing 37 'on the guide rail 311, the latter - viewed in the longitudinal direction of the ski - has recesses 313 which are arranged at intervals from one another and in which a not-shown locking bolt of the housing 37' can optionally be used in a known manner. The guide rail 311 is provided with a downward projection 38 ′ with a square cross section, which can be inserted into the hole 39 b with a square cross section of the row of holes of the connecting element 3 according to FIGS. 14 and 15. It is also possible to use the connecting element 3 'according to FIG. 15a for a ski binding according to FIGS. 16 and 17.

18 and 19, the ski brake 25 has a base 25a which is fixedly connected to the heel holder 5, and a pedal 58 which carries a roller 59 at its free end, the axis 59a of which extends transversely to the longitudinal direction of the ski 2.

Between the toe piece, not shown here, and the heel holder 5, the connecting element 3 is provided with a casing 14 made of plastic material, of which only a partial area is visible in FIG. 18.

As can be seen from FIGS. 18 and 19, the pedal 58 consists of a support body 58a and an actuating flap 58b which can be displaced perpendicular to the support plane of a ski boot 23. The support body 58a is articulated to the base 25a of the ski brake 25 via a positioning spring 61. In the support body 58a there are the bearing sections 62a of two brake mandrels 62, the cranked ends 62b of which protrude from the support body 58a are accommodated in recesses in the actuating flap 58b. In the operating flap 58b is white ters the roller 59 stored.

In the braking position of the ski brake 25, the two brake mandrels 62 protrude with their brake blades 62c under the tread of the ski 2, and the pedal 58 forms an acute angle 06 with the top of the ski 2 (see FIG. 1).

If the skier climbs into the ski binding with his ski boot 23, the pedal 58 and the two brake mandrels 62 are pivoted counterclockwise. First, the support body 58a comes to rest against the sheathing 14. If the pressure on the actuation flap 58b is increased, it moves perpendicular to the support plane of the ski boot 23 relative to the support body 58b in the direction of the top of the ski 2. In the swung-down position of the ski brake 25, the actuating flap 58a is pressed down against the force of a further spring, not shown here, as a result of which the cranked ends 62b are pivoted against the vertical longitudinal center plane of the ski 2 by means of their bent ends 62b, so that the two brake pins 62 with their brake blades 62c are within the ski outline. The diameter of the roller 59 mounted in the actuating flap 58h is dimensioned such that when the actuating flap 58b is depressed, the roller lies on the one hand or on the cover 16 on the casing 14 / and on the other hand the sole 25a of the ski boot 25 is pressurized (see FIG .18).

The use of such a ski brake 25 is particularly advantageous because the front part of the pedal 58, which is removed from the person holder 5, is used for pressure transmission. Since the roller 59 is located at a distance from the heel holder 5, bending of the ski 2, which is caused by the toe piece 4 and the heel holder 5 when the ski boot 23 is clamped, is counteracted with increased counter-torque.

The embodiment of a ski binding shown in FIGS. 20 and 21 has a heel holder 5 which is coupled to the toe piece (not shown) via a connecting element 3.

In contrast to the embodiment according to FIGS. 18 and 19 be sits the ski brake 25 ', the base 25' a of which is also connected to the heel holder 5 here, a roller 59 '; however, when the pedal 58 'is depressed, it does not rest on the casing 14 for the connecting element 3. "Rather, in the driving position, the actuation flap 58'b is supported on or on the cover 16 'of the casing 14 / by means of two lugs 24, which extend from the

The actuating flap 58'b protrude downward and are arranged symmetrically with respect to the vertical longitudinal center vein of the ski brake 25 '. The ski boot 23 itself rests on the support body 58'a and on the roller 59 'in the driving position (see FIG. 20).

The ski brake 25 "according to FIG. 22 differs from the last described embodiment in that the actuating flap 58", which has a roller 59 "" and two lugs 24 ', opens directly onto these lugs 24' without interposing a casing 14 the top of the ski 2 rests. This construction has the advantage that through the two lugs 24 'when the pedal 58 "is pressed, a guide for the actuating flap 58" b on the narrow-bore or. the cover 16 tenflachen the casing 14 / takes place. The ski boot 23 rests on the support body 58 "a and on the roller 59" in the driving position.

23 is characterized in that in the ski brake 25 '"the roller 59"' is supported on the upper side of the ski 2 via the connecting element 3. The connecting element 3 has a support 3c or 3d in this area both on its upper side and on its lower side. These are firmly connected to the connecting element 3 by means of Meten 3e.

The embodiment of a connecting element 3 shown in Fig. 24 is characterized in that it or the like with an elastic layer 71 made of foam rubber, foamed plastic. is provided, which is sprayed directly onto the connecting element 3.

In contrast, in the embodiment according to FIG. 25 the connecting element 3 is provided with a casing 14 made of a plastic material, to which an elastic layer 71 is applied. Sheath 14 and elastic layer 71 have different moduli of elasticity.

The embodiment according to FIG. 26 is characterized in that the connecting element 3 - seen in cross section - is half surrounded by the casing 14 'made of plastic material, whereas the other half is covered by an elastic layer 71'. The casing 14 'and the layer 71' are connected to one another by two weld seams 72 which run in the longitudinal direction of the ski 2.

In the embodiment according to FIG. 27, the connecting element 3 is surrounded by a casing 14 made of plastic material. On the underside of this casing 14 an elastic layer in the form of a thick film 73 is attached, e.g. glued or vulcanized.

28 shows the structural reversal of the last-described embodiment. The connecting element 3 is again surrounded by a casing 14 made of plastic material. The film 73, however, is glued to the top of this casing 14.

In the embodiment according to FIG. 29, the connecting element 3 is surrounded by a casing 14 which, viewed in cross section, covers the upper side of the connecting element 3, the two side faces and the two edge areas of the underside. An elastic layer 71 is bonded to this underside of the connecting element 3, which connects the two edge regions of the casing 14 resting on the underside of the connecting element 3.

30 differs from this constructive solution in that first the elastic layer 71, which here is approximately T-shaped in cross section, is glued to the underside of the connecting element 3, after which the casing 14 on the top and the two Narrow side surfaces of the connecting element 3 attached becomes. The two end regions of the casing 14 overlap the ends of the elastic layer 71 which is T-shaped in cross section and each have a step.

In the two following exemplary embodiments, the elastic layer 71 is arranged on the underside of the connecting element 3. But it can also be attached to the top of the connecting element.

According to the embodiment according to FIG. 31, the elastic layer does not extend continuously over the entire length of the connecting element 3, but is divided into several sections 71 ", which have regular distances" a "from one another.

32 has an elastic layer 71 "'which is continuous in the longitudinal direction of the ski 2 and which is glued to the underside of the connecting element 3, but this layer has flat projections 74 which protrude downwards and which b" b "at regular intervals. from each other.

The embodiment of a ski binding shown in FIG. 33 is characterized in particular by the fact that the toe piece (not shown here) and the heel holder 5 are not connected to one another via a connecting element and are therefore independent of one another.

The base 25 a of a ski brake 25 is firmly connected to the heel holder 5. As in the exemplary embodiment according to FIGS. 18 and 19, the ski brake 25 has a pedal 88 which consists of a support body 88a and an actuating flap 88b, the latter carrying a roller 89 at its free end. The arrangement and the function of the two brake mandrels 92 correspond to that of the embodiment according to FIGS. 18 and 19.

However, the axis 89a of the roller 89 on the actuating flap 88b is arranged offset slightly downward from the aforementioned embodiment. The ski boot 23 therefore does not rest on the roller 89 but in the driving position on the top of the actuation flap 88b. The production pressure is Via the actuating flap 88b, via the axis 89a and via the roller 89 directly (without interposing a sheathing) to the top of the ski 2.

The embodiment of a ski binding according to FIG. 34 is similar to that shown in FIG. 33 insofar as in this ski binding the front jaws, not shown, and the heel holder 5 are fastened independently of one another on the upper side of the ski 2. The actuation flap 88'b of the ski brake 25 therefore rests on the top of the ski 2 when the pedal 88 'is depressed. As in the previous exemplary embodiment, the ski boot 23 also rests in the driving position on the support body 88'a and on the roller 89 'mounted in the actuating flap 88'b. In addition, the actuating flap 88'b has two lugs 24 "with which it rests directly on the top of the ski 2. The individual sections of the brake mandrels 92 'are designated by 92'a, 92'b and 92'c.

The invention is not limited to the exemplary embodiments shown in the drawing and described above. Rather, various modifications thereof are possible without leaving the scope of the invention. For example, any other known locking devices known per se can also be used for locking the connecting element on the guide rail.

Furthermore, the same connecting element can be used for the embodiment according to FIGS. 14-17 with a ski-fixed toe piece or with an adjustable toe piece, which has advantages during manufacture. The connecting element according to FIGS. 14 and 15 or according to FIG. 15a can also be used in connection with a front jaw or with a guide rail for a front jaw, in which the extension is designed as a cylindrical pin, since, as already mentioned, the Side walls of the square hole touch the circumference of each cylindrical hole. The same applies to a configuration of the projection with a polygonal or non-circular cross-section. In this way, the area of use of the connecting element according to the invention is further expanded.
