The shape of the sole as possible following, with a climbing up Has the shoe-tying surface provided holder.

Jaws for ski bindings with a sole retainer that has a surface for the bracket that prevents the shoe from climbing up, are in different designs known for a long time. For example, OE-PS 292 525 describes a toe piece for ski bindings as mentioned above named type, in which the sloping surface has protruding parts on the sides of the shoe, which are only located on both sides of the shoe, releasing its Support the tip. However, this toe piece has the "disadvantage that the adaptation of the sole hold-down device to the shape of the Shoe tip is only partially realized.

In another known embodiment according to OE-PS 208.276, the sole edge holder has flanged flaps on, which form a holder for a sliding attachment rubber. This version again has the disadvantage that the attachment rubber has no steps.

In another known embodiment according to DL-PS 17 218, the hold-down device consists of metal plates between which have a step-shaped, elastic tip stop, e.g. made of slats made of rubber. In this embodiment, the plates are for example held together with a screw provided with a miU wing nut. The assembly work is disadvantageous here, since the sequence in order to achieve the step-like formation of the individual plates, both the rubber plates and the metal plates, must be strictly adhered to.

However, this makes assembly time and costs unfavorable elevated.

There are other sole hold-down devices known, which have stepped brackets, even if they do not relate to the subject-matter mentioned at the beginning. So e.g. the DL-PS 19 483 describes a safety ski binding, in which a sole holding unit with stepped contact surfaces is provided. This version refers to a cable tie, in which the ski boot is pressed from behind by the cable pull against the inclined surfaces of the sole holder will. With regard to the material used here, this patent specification does not contain any information.

The binding according to PE-PS 1 445 755 is used for holding of the ski boot, a material which has a very low coefficient of friction in relation to the material of the ski boot should have. A step-by-step design of the hold-down device was not disclosed.

The invention is based on the object of further developing a jaw of the type mentioned at the outset in such a way that the holder between the sole hold-down device and the insert simple, reliable and, if necessary, allowing easy replacement is designed. In addition, the insert should not only be approximately, but precisely on shoe soles with different Radii can be adjusted.

According to the invention, the object set is achieved by that the sole hold-down device has at least one holder for the insert and the insert on its facing away from the sole Back at least one with the bracket

acting approach that a holding element holding the holder and the approach together is provided ', and that the front of the insert facing the sole forms the support surface.

The inventive design of the baking is daü Set goal achieved in every detail. The connection between the hold-down part made of solid material, preferably made of metal, and the insert with a fixed holding element, e.g. pin, is easy in terms of assembly time, in the holder and allows if necessary easy replacement of the insert.

Characterizes a particularly favorable embodiment of the invention characterized in that two wings are provided as a holder for the insert, which are made of one from the wall solid material formed hold-down part of the sole hold-down, corresponding to the outer surface of the attachment, preferably essentially parallel to each other, bent or developed and each with a hole for Recording of, e.g. trained as a pen, holding elements are provided.

In this way, the hold-down part of the sole hold-down device can be designed in the usual form, whereby the Punching out the side wall and forming the wing a symmetrical holder for the insert is created. At the Therefore only a pin is to be used, which can preferably be a little thicker than the bore or holes. whereby a firm hold between the metal part and the insert is achieved. This makes the known types of fastening, such as gluing or vulcanizing the insert

_ 5 - 50982 1 / 063A

the sole hold-down, obsolete. Besides, it is then It is no longer important whether an adhesive relationship can even be established between the two layers and, if so, how much effort is involved «

According to another inventive idea the baking is thereby characterized in that the sole hold-down on the hold-down part for receiving the insert has a rear outgoing part with a substantially horizontal has lying, transversely to the front jaw extending bore for the holding part formed by a pin. on In this way, the sole hold-down device is designed to be particularly robust, and assembly is just as easy as with of the previous version.

Yet another embodiment of the invention Backens is seen in the fact that a bent lobe is formed in the jaw to hold the insert, the cooperates with a part of a jaw cover, the tab and the cover part with holes for one the holding part forming pin are provided, and that the approach of the insert with a rear extension is provided, which engages between the flap and the cover part and with a substantially perpendicular Bore is equipped to receive the pin.

This embodiment enables the use of the insert also for those cases in which the sole hold-down device as Part of the jaw or the housing of the jaw and not designed as a separate part.

Yet another embodiment consists in the fact that the jaws, as is known per se, have a retaining ring or the like.

509821/0634 - 6 -

for a lanyard, with! parts of the retaining ring, e.g. the free ends of the same with an open ring, are intended as holders for the insert in the jaw.

In this case, the retaining ring of the lanyard becomes the same used as a holding element between the sole hold-down device and the insert. This eliminates the need for a separate one Component.

According to a further idea of the invention, the bore for the brackets offset backwards by a small amount compared to the hole in the attachment of the insert sow. As a result, a particularly firm holding of the insert in the hold-down part or in the jaws is achieved, since the Insert lies in the holder with a certain pretension. Thus, one becomes due to fatigue resulting looseness are prevented.

Embodiments of the invention "are based on the following the drawing explained in more detail. Here show:

1 shows a section through part of the sole hold-down device of a jaw according to the invention along the line I-I in Fig. 2;

Fig. 2 is a side view partly in section of the jaw of Fig. 1;

3 is a perspective view from the rear of another embodiment of one according to the invention Baking;

4 shows a section of another embodiment similar to FIGS. 2 and

5 shows a section through one provided with a retaining ring for a lanyard Baking according to the invention.

As can be seen from the embodiment according to FIGS. Ί and 2, a sole hold-down device 1 is provided on an only indicated jaw 10, which has a hold-down part 2 made of solid material, preferably metal, and an insert 3 made of plastic material, preferably rubber. ^{The sole L} V coming to rest in the insert 3 is indicated by dash-dotted lines.

The insert 3 has its back facing away from the sole 4 at least one approach 6 cooperating with a holder. Im cooperating with the bracket Area is the material of the approach 6 excluded in order to achieve a good edition. The bracket consists of two Wings 11, which are formed from the material of the Mederhalteeil.es. They correspond to the outer surface of the approach 6 and are essentially parallel to one another and are from the inclined sides of the hold-down part 2 curved or angled. Both the wings 11 and the extension 6 have bores 11a or 6a, which serve to receive a holding element, for example designed as a pin. The holes 11a the wing 11 are arranged in the present example so that they are aligned with the bore 6a of the projection 6, if the insert 3 lies exactly in the hold-down part 2. the Bores 11a can, however, also be offset a little to the rear, the "rear" being the one on the hold-down part 2 attached part of the approach 6 is meant. This creates a certain pre-tensioning of the plastic material the insert 3 reached in the holder.

In the embodiment of FIG. 3 is for inclusion of the insert 3 with a rearwardly pronounced part 13 approximately triangular side surfaces are provided. In this one is essentially horizontal and transverse for baking 10 extending bore 13a provided, the can also accommodate a pin 12. '

4 shows another embodiment of the bale 10. In this case, in the jaw 10 is a bent flap 14 with a bore 14a and a cover part 15 with a Bore 15a formed. A hole? ' of an approach 6a is aligned with the bores 14a, 15a and is essentially vertical to the ski plane. TJm the cheek 10 to close at the front, front tabs (not shown) from the housing, which is made for example of sheet metal be bent on both sides.

Ih the Fig. 5 is the holder by a retaining ring 1? formed, which is provided at the same time for a conventional lanyard, bent parts 17a and 17b of the retaining ring 17 penetrate bores 18a of the side walls. 18, wherein between the side walls 18, the insert 3 with a for receiving the ends 17a, 17b suitable bore 16 is provided.

In all of the designs, the front side 8 of the insert 3 facing the shell 4 can have a dimpled support surface 9 exhibit. It is also conceivable that these knobs have different curvatures in steps and / or in groups Have radii. As a result, shoe soles of different curvatures can be adapted to the binding.

The invention is not limited to the examples given. Various other designs are conceivable which "realize the connection between the insert and the holding-down part within the scope of the invention and have a different configuration. For example, two or more pins can be provided as holding elements, which are shown in FIG are used side by side parent wings. This embodiment allows the use of two or more lugs. also, the recess may be other than in Fig. 1 ready to be Daxin are also the wings to approach or to otherwise deposit..

A plurality of holding elements can also be provided for holding the insert 3 in the holding-down part 2. In particular this is conceivable in the embodiment according to FIG. 3, where the holding-down part 2 has a rearwardly pronounced one Part 13 is provided. A horizontal or vertical position for the retaining element is generally preferred. However, it is conceivable to also arrange the holding element at an angle. If two holding elements are used in conjunction with one another, they can also cross each other, where, then that one is made stronger in the middle area than the other in order to enable the formation of a hole, through which the other pin is passed. This bracket is particularly preferable for sturdy insoles, where the insert is very heavily used in relation to the holding part.
