Description

. Gerundete Zehenführungsbacken für rund geschweifte Sohlenumrißformen sind bekannt.. Rounded toe guide jaws for curved sole contour shapes are known.

Diese geschweiften Backen müssen schon bei der Herstellung der Backen ihre gebogene Form erhalten.These curved jaws must be curved when the jaws are manufactured Maintain shape.

Ein Nachteil, der vielen Aufschraubbin-A disadvantage of many screw-on fasteners

dungen dieser Art anhaftet, ist aber der, daß sie nicht genau der Sohlenform angepaßtThis type of application adheres, but is that it is not exactly adapted to the shape of the sole

, werden können. ' Wird der vielfach von Skiläufern gebrauchte Bergstiefel verwendet, so muß der senkrecht stehende Zeihenführungsbackenteil der meist gebogenen Umrißform des Vorderteiles; dier Stiefelsohle möglichst genau angepaßt werden, um einen festen Sitz des Stiefels in- der Bindung zu gewährleisten. Das der gebogenen Stiefelsohlenumrißform entsprechende Biegen des senkrechten Zehenhackenschenkels ist jedoch nicht ohne weiteres möglich, da ja der waagerechte Zehenhackenschenkel zur Biegerichtung hochkantig liegt und der Werkstoff beim Anpassen in sich gestaucht oder gestreckt werden müßte. Dieses anpassende Biegen könnte daher nur in warmem Zustand oder mittels eines der Sohlenform .entsprechenden Gesenkes ο delegier Schablone durchgeführt werden., can be. 'Is often used by skiers used mountain boots, the vertical toe guide jaw part must the mostly curved outline of the front part; the boot sole if possible must be precisely adjusted to ensure a tight fit of the boot in the binding. The bending of the vertical heel leg corresponding to the curved outline of the boot sole However, this is not possible without further ado, as the horizontal shackle of the toe is used to the bending direction and the material is in would have to be compressed or stretched. This adaptive bending could therefore only in a warm state or by means of a die corresponding to the shape of the sole ο delegier Stencil to be carried out.

Gegenüber diesen bekannten Zehenführungsbacken für Skibindungen unterscheidet sich der Backen gemäß der Erfindung dadurch, daß der Zehenbackenauflagescihenke] bis an den senkrecht zum Ski stehenden vertikalen Backenschenkel reichende ScMitzungen (Aussparungen) aufweist, welche das leichte Biegen' des Backens an gebogenen Sohlenumrißformien beim Anpassen ermögliehen. Compared to these known toe guide jaws for ski bindings the jaws according to the invention in that the toe backrest Sessions reaching as far as the vertical jaw legs, which are perpendicular to the ski (Recesses), which allow the easy bending 'of the jaw on curved Enable sole contour shapes when adjusting.

Bei der Erfindung werden also die angeführten Nachteile vermieden. Es kann hierbei auch als Fersenzugriemen nach bekanntem Muster ein Umlaufriemen in Form eines durchgezogenen Langriemens verwendet werden, der keinem Verschleiß ausgesetzt ist. Die StiefelauflagefLäche auf dem SId ist vollkommen eben, und die senkrechten Zehenbackenteile können bei der Montage von jedermann leicht auch einer gebogenen So!hlenumrißform ,angepaßt werden, ohne hierbei Spezialwerkzeuge verwenden zu müssen. Ein weiterer Vorteil besteht darin, daß durch den vor den Zehenhacken vorbeigeführten Fersenzugriemen, der mit seiner unteren Kante auf dem Ski aufliegt, ein Eindringen von Schnee zwischen StiefelsoHe und Ski (Bindungsbacken) vermieden wird und daher keine Ballung und Verkrustung durch gefrörenen Schnee unter der Sohle stattfindet, so daß der Stiefel immer eben mit seiner ganzen Trittfläche aufliegen kann.In the invention, the disadvantages mentioned are avoided. It can do this A circulating belt in the form of a continuous long belt can also be used as a heel pull strap according to a known pattern, which is not exposed to wear and tear. The boot surface on the SId is perfect flat, and the vertical toe cheek parts can be used when assembling everyone can easily also have a curved hollow shape , can be adjusted without having to use special tools. A Another advantage is that the heel strap passed in front of the toe heel which rests with its lower edge on the ski, a penetration of snow between the boot sole and ski (binding jaws) is avoided and therefore no agglomeration and incrustation due to frozen ones Snow takes place under the sole, so that the boot is always flat with its whole Can rest on the tread.

In der Zeichnung sind die Bitidungshacken für den rechten Fuß sowohl in geradem (Abb. ι im Aufriß und Grundriß) als auch in dem der gebogenen Sohlenform angepaß-In the drawing are the bitidation hooks for the right foot both in straight (Fig. ι in elevation and plan) and in which the curved sole shape is

th states (Fig. 2 only in plan). The version for the left foot is then the mirror image of the drawn Shape.

The horizontal jaw support leg part has slots or recesses Z, so it consists only of tabs L, which are used to attach the jaw to the ski. The slots Z extend as far as the vertical ίο cheek limbs B and thereby enable this part to be easily bent, since the horizontal bath thong no longer offers any resistance to bending.

In the case of the curved jaws shown in Fig. 2, which are adapted to the shape of a boot, one can see how the ends of the flaps have approached one another as a result of the bending of the vertical jaw limb B.

In the case of ski bindings with screw-on jaws, it is known to either anchor the heel pull strap in parts to the upright thighs of the toe or to guide it around the toe of the boot in one piece past the toe cheeks. The latter type is also used in the screw-on jaws according to the invention. For this purpose, each horizontal jaw limb according to the invention has an extension at the front end that is bent up and down in such a way that it forms a hook or an eye // through which the circulating belt is pulled and thereby comes to rest with its lower edge on the ski . The hook or the eye can also be designed (H ₁ in Fig. 4) so that the strap is inclined to the ski. Compared to hold-down members, which are formed on parts separate from the jaws, there is the advantage in the present case that one and the same flap of the horizontal jaw part serves both to attach the hooks and the upright jaw part. As a result, however, the distance between the means of the fastening screw and the hook, which is effective for bending loads, is reduced to the smallest possible extent and, moreover, the sole of the boot is no more than the thickness of the horizontal one! Parts of the cheek, removed from the ski shaft. The strap, which is held down by the hooks on the ski, prevents snow from penetrating under the boot sole.

The vertical toe cheek part B has, in the usual shape, a hook N backwards on its outside, which holds the belt down, whereby the downward diagonal pull is achieved when lifting the heel, but in contrast to known designs, a weakening of the cheek part by incisions to Hook formation is avoided.

Fig. 3 shows the binding jaws mounted on the ski S. The toe strap is omitted for clarity. The fixation is done by ordinary wood screws. You can see the belt U running through the hooks or eyes // and under the hooksN, which is provided with the usual heel parts with tensioners. Adjacent to the mounted jaws is a support.4 attached to the ski in the thickness of the jaw material. A protective plate should be placed over this support and the horizontal parts of the two jaws; in the width of the support that reaches up to the front hooks //.
