Austria-Austria (AT) A 5390/76 (71) Fischer Gesellschaft mhH, Griesgasse 10-11, A-U9IO Ried im Innkreis, Austria-Austria (AT) (72) Adolf Staufer, Ried im Innkreis, Rudolf Hieblinger, Ried im The present invention relates to a ski band with a support plate in front of the toe point and a support plate adhering to the extension of the toe-soled shoe sole and its sole. associated with bent-up longitudinal edges between which a space is formed for insertion of the tapered tip of the ski shoe, the bandage comprising an openable retaining device which prevents the extension of the shoe sole from rising from the support plate and a ski shoe suitable for this bandage.

Ski bindings with a toe iron and a handle pivotally attached to the ends of the arms are already known, which bracket can be fastened in a turned-down position to the longitudinal centerline at the front end of the toe iron by a pivotally mounted toothed rod-like lever. To prevent the shoe from moving backwards, pins projecting upwards from the base plate of the toe iron are provided, into which the shoe is fitted to the extension of its sole by means of holes made in the side of the sole. In another similar embodiment of the ski bandage, the shoe is fastened by means of retaining pins from above. Bindings of this type are bulky and extend beyond the longitudinal edges of the ski with a considerable portion of the side guides, resulting in high friction between them and the track.

63337

The ski bandage according to Swiss Patent Publication 147,184 has a corner support plate suitable for a wedge-shaped shoe, on which a narrow guide strip is attached by a hook inside the toe point, which engages at the edge of the sole of the shoe in a corresponding groove on each side of the upper. The narrowing point thus formed must be wider than the shoe, resulting in an unreasonably wide bandage which is not suitable for narrow skis.

Finally, ski bandages are known which have a toe or support plate arranged in front of the toe and toe, the tip part of which has a box-like cross-section for fitting an extension of the shoe sole to it, which can be fastened to the bandage by means of a projecting pin. Although the advantage of these toe irons is their small size, which creates little friction with the track and their weight is small, but the attachment of the shoe is unnecessarily precise, which is also to be feared.

The object of the present invention is to provide a toe iron, i.e. a support plate, which has the latter advantages but not the above-mentioned disadvantages. This object is achieved by a ski band of the quality shown at the beginning according to the invention, thus, when viewed from above, the base plate has a constriction point between both end edges, from which the space formed between the longitudinal edges expands towards both end edges of the plate.

A ski shoe according to the invention with a ski-like shoe sole extension for a ski binder according to the invention is characterized in that the shoe sole extension is tapered from the sole towards its tip and forms a mutual constriction, i.e. a narrowing point, involving an extension of the shoe sole extension.

Other details of the invention will be explained in more detail with reference to the drawing, which shows an application example of a ski bandage according to the invention and a shoe suitably formed for this purpose. In the drawing, Fig. 1 shows a top view of a ski tie support plate with shoes fitted therein, Fig. 2 shows a section taken along line II-II of Fig. 1 with the shoe fitted 3 63337, Fig. 3 shows a side view of the support plate with the shoes fitted and gripper 4 seen from the side, the support plate as well as the shoes fitted in place.

Reference numeral 1 denotes a support plate for a ski tie according to the invention, i.e. a toe iron which, when viewed from above, tapers towards the tip of the ski and has a taper 2 near the tip end through which a bracket 3 transverse to the longitudinal axis of the ski passes. upwardly drawn longitudinal edges 7, 8, between which the extension 9 of the sole of the ski boot 10 will be located.

The bracket 3 is made of a resilient material and its other end is pivotally mounted on a loop 11 at one end of the longitudinally pulled longitudinal edge 8, while the other end of the bracket 3 is bent into a gripper 12 and can be retained in a notch 13 in the longitudinal edge 7.

The upper side of the shoe sole extension 9 is curved, i.e. formed in a cross section transverse to the skiing direction, i.e. convex, this curvature being made to tighten the handle more easily asymmetrical with respect to the ridge of the loop 11 in which the loop is mounted.

The handle 3 has a bend 15, by means of which it is secured against rotation in the tightening position. The bend shown in the handle can be replaced by any shape of the curvature of the handle in the skiing direction or by a flat design which achieves the same result. In the present case, the headband is made of a spring rod.

The fitting of the shoe to the support plate 1 takes place from above, as already tentatively mentioned as an advantage of the ski tie according to the invention, the handle 3 being turned back or opened, after which the bracket 3 is locked under increasing prestressing, i.e. turned down and retained in the notch 13. the sole of the shoe is restrained in a bandage. Displacement of the extension 9 from under the handle 3 can be prevented by various measures, for example by making an extension 9Λ or a protrusion in the outwardly projecting part over the constriction of the shoe sole 2. .

4,63337

Since the sole of the shoe, possibly including the upper, is die-cast, molded or otherwise made of plastic, there is no difficulty in giving the extension of the sole of the shoe 9 an arbitrary shape suitable for the intended purpose.

Of course, within the scope of the invention, various structural changes can be made. Thus, for example, it is possible to give the upper side of the shoe sole extension a certain curvature alternatively with respect to either the bracket 3 or both parts. When the extension 9 of the shoe sole is sufficiently compressible, the bracket 3 can be made rigid or only slightly flexible.

Finally, it is also possible to use other retaining devices instead of the pivotable handle 3, which, when fitted to the support plate, prevent the shoe sole extension 9 from rising from the support plate 1 in the bandage attachment position.

Claims (2)

5,63337 A ski bandage, in front of which the toe point has a support plate gripping the extension of the toe-side sole of the ski, its sole plate (4) and associated bent longitudinal edges (7, 8) between which a space for inserting a tapered tip of the ski boot is provided, the bandage comprising an openable grip , which prevents the shoe sole extension from rising from the support plate, characterized in that the sole plate (1) has a narrowing point (2) between the two end edges when viewed from above, from which the space between the longitudinal edges (7, 8) expands towards both end edges of the plate. A ski shoe with a ski toe-side shoe sole extension for a ski binder according to claim 1, characterized in that the shoe sole extension (9) tapers from the sole towards its toe and forms a mutual constriction, i.e. a narrowing point, involving an extension of the shoe sole extension.
