Description

description

The present invention relates to a ski binding having one of one releasably held release device attached to the ski surface as a support for a soft, ambulatory shoe with a plate in the area of the forefoot arranged, the shoe on the plate holding element and with one to both Sides of the plate hinged back support.

From US-PS 3,854,743 a shoe stiffener is known, which in essentially has the features mentioned above.

However, the known shoe stiffening has the disadvantage that the articulation point the restraint is arranged relatively high above the plate. Therefore, the Transporting the ski this shoe stiffener can be removed from the ski, as the backrest support would protrude bulky over the ski surface even when folded forward. In addition, a forward folding is the rear support of the known shoe stiffener not intended for the transport of skis at all. The reclining support is by means of firmly connected to the lower heel cup with a rubber band.

Furthermore, in the known shoe stiffening, the attachment of the Shoe relatively complicated and cumbersome, and in particular does not ensure a safe Hold the boot on the skis. Furthermore, it is disadvantageous in the known shoe stiffening that the plate must be made adjustable in length in order to adapt to to be able to make different shoe sizes.

The present invention is therefore based on the object of a To create ski bindings of the type defined at the beginning, which both with regard to the Transport and use is easy to handle and also safe Secure hold for the boot on a ski.

This task is made possible by the characterizing features of the claim 1 solved.

The ski binding according to the invention allows unhindered entry as well as an extremely simple attachment of the shoe to the plate. For transport the ski can fold the ski binding according to the invention in a very confined space do not and does not protrude beyond the ski surface than the previously known ones Ski bindings.

Furthermore, the ski binding according to the invention has the advantage that it has a secure hold guaranteed even with extremely soft shoes.

Further advantageous features of the present invention are set out in FIGS Described subclaims.

In the following the invention with reference to schematic drawings of Exemplary embodiments explained in more detail: FIG. 1 shows a first exemplary embodiment a ski binding designed according to the invention with a ski boot in a side view, FIG. 2 the ski binding according to the invention according to Fig. 1 in the folded state in a side view, Fig. 3 a ski boot that is used both for the ski binding designed according to the invention as is also suitable for a commercially available cross-country ski binding, and FIG. 4 a second one Exemplary embodiment of a ski binding with a ski boot designed according to the invention in side view.

On a ski 1 is a plate 2 in a known manner an elastically releasing device 3 and counter bracket 4 detachably held. In the front, angled part 5 of the binding plate 2 is a trough-like Recess for receiving a spring-loaded pressure body of the release device 3 and a horizontally and transversely to the ski 1 longitudinally extending bore, which a bearing pin 6 receives about which a retaining cap t is pivotably mounted. The retaining flap 7 extends approximately to the Rlst and consists at least in the front Area made of a rigid material, preferably plastic. The retaining flap 7 includes the forefoot and the instep laterally and from above and is in the form of an approximately U-shaped Half-shell formed. The retaining flap 7 has a sawtooth-like shape on its upper side Latch 8, in which a closing element 9 can be latched with a wedge-shaped cutting edge Is. The closing element 9 is designed as a central buckle and is attached to a clamping bracket lo mounted pivotably, the legs of which extend downward on both sides of the shoe and the free ends of which are pivotably mounted in transverse bores 11 of the plate 2.

The rear part of the plate 2 has one on each side Tab 12 open. The tabs 12 are with Holes for the recording of pivot bearings 13 for a back support 14 is provided. The backrest 14 is therefore pivotably mounted in the heel area directly above the plate 2.

The rear support 14 is in the form of an approximately U-shaped bracket or a U-shaped half-shell with side cheeks 15 arranged in the upper area.

Its upper part includes the lower leg and its lower part Part the heel area from the back and from both sides.

The rotational movement of the rear support ld about the bearings 13 is to the rear limited by an extension 16 supported on the plate 2. Between the Extension 16 and the plate 2 are elastic intermediate layers 17 for damping shock loads arranged.

The elastic intermediate layers 17 advantageously consist of one or several layers that are self-adhesive on one side and bonded one above the other, being the bottom layer on top of the plate or the top layer is glued to the underside of the extension 16.

By adding or removing layers, the slope of the Back support 14 can be adjusted according to individual needs. A mechanical adjustment device would also be conceivable.

The back support 14 transmits back and side forces (Edging) from the lower leg to the ski.

If via the backrest 14 also forward forces from the lower leg To be transferred to the ski, the extension 16 and thus the back support 14th e.g. by means of a locking device arranged on the plate 16. ' be held in their position.

One of the two side cheeks can be used to transfer the forward force 15 be extended by the mirror lS encompassing the tibia. The latch 18 is provided with a knob 19, over which a bracket 20 together with a buckle 21 clamps the lower leg in the rear support 14. To transfer the forward forces it may also be sufficient for the side cheeks 15 to be elastically resilient and the lower leg almost completely comprehensive training.

The central locking element is used to get out of the binding 9 and, if available, the buckle 21 open. For more convenient handling can it may be advantageous, the retaining flap 7 and the backrest support 14 by an elastic Pre-tension the element, e.g. a torsion spring, in the open position. The reserve support 14 is then supported under the influence of the spring with its extension 16 on the binding plate 2 from, while the retaining flap 7 is opened by the spring so that a comfortable Getting in and out is guaranteed.

To transport the skis, as shown in Fig. 2, the back support is used 14 folded onto the retaining flap 7 and pushed down so far that the rare cheeks 15 grip the ski sideways. In this way there is a compact transport position achieved. If the retaining flap 7 and the backrest support according to the above explanations are spring-loaded, the return support 14 is preferably in the transport position by the holding member consisting of the bolt 18, knobs 19, bracket 20 and buckle 21 held, with latch 18 and bracket 20 over the Ski base laid will. The holding member described can also be used to hold both skis together and replace the conventional ski clips.

For longer transports, e.g. on the car roof, the entire binding removed by releasing the plate 2 and separately to protect against contamination be stowed away.

To meet the safety requirements when plate 2 is triggered leash straps (safety rope) or ski brakes are equally possible.

The shoe 22 is made of soft material and has in particular Addition before upholstery in the area of the system of the back support 14 and the retaining flap 7th

Furthermore, the drawer 1 is preferably with an ink-proof sole and a closure made of which, non-depositing material yçrghen. The upholstery material should be good heat insulating. Furthermore, the shoe should have a waterproof outer skin be provided.

In the sole is for fixation and better transmission of the torsional forces a groove 23 extending in the longitudinal direction of the ski is let into which a the plate 2 attached spring 23 protrudes.

The foremost part 25 of the sole is preferably shaped so that it fits into a conventional cross-country ski binding.

This means that the shoe 22 can be used for both alpine and Nordic Find skiing use. Certain parts of the shoe 22, in particular the contact areas with the RücklagestUtze 14 and retaining flap 7 as well as the ankle joint area are preferred reinforced trained.

Since the currently available ski pants often use the top buckle of the ski boot e.g.

be attached to the boot shaft by means of a rubber band, The rest support 14 preferably has a bead 2t. The bead 26 is above the heel and serves as a hold for the said elastic at the lower end of the currently available ski pants.

Another embodiment of the ski binding according to the invention is shown in FIG Flgurso designed that the retaining flap 7 in the closed state on the backrest support 14 is supported in such a way that a stiff one surrounding the lower leg on all sides Cuff arises. The retaining flap 7 is for this purpose extended like a tongue, i.e. over teacge up the instep. The tongue-like extension is in the V $ g.4 Exemplary embodiment shown by the bolt ia, IUget 2o and buckle 21 held.

In this way, the movable parts 7 and 14 are formed together with the base plate 2 a self-contained stable or rigid body. at the embodiment shown in Figure 4, the locking device 8, 9, lo omitted. Furthermore, in this embodiment, the locking device 16 'for the back support 14 is omitted.

All information and characteristics disclosed in the documents, in particular spatial design are claimed as essential to the invention insofar as they individually or in combination are new compared to the state of the art. Blank page
