The invention relates to a water ski binding consisting of a toe cap attached to the ski and a heel cap that is attached to a heel plate located behind the toe cap is, which can be displaced in the longitudinal direction of the ski with the help of guides and to adjust the binding different foot sizes can be determined.

Water ski bindings must be built so that the user can easily insert his feet and easily can pull out. Nevertheless, it is necessary that the water skis are firmly attached to the at all times when they are in use Feet. It is therefore important that the bindings are adapted to each foot length can. To enable this setting, the position of the heel cap is essential for many water ski bindings changeable.

In a known binding, the heel counter is attached to a heel plate which is on the surface of the ski. Through two slits in the heel plate running in the longitudinal direction of the ski grip two screw bolts held in the ski. With the help of nuts the on this Way in the longitudinal direction of the ski heel plate was determined in the desired position. Even though So the heel plate is pressed against the ski by the nuts, it can happen that the Heel plate by the force acting on the heel cap during use in the longitudinal direction of the ski is moved. This means that the user's foot no longer finds a firm hold in the Binding.

In another known binding, the rear part of the heel plate has one in the longitudinal direction of the ski running slot, from the laterally directed, hook-like slots go off. A screw shaft held in the ski extends upwards through this slot structure. To adjust to different foot lengths, the end of one of the hook-like slot parts must in each case brought to rest on the screw shaft. The heel plate is then secured using a Mother pressed against the ski. The front end of the heel plate is between the side, on the ski straps attached. In this training there is no longitudinal displacement of the Heel plate possible when using. The attitude towards different foot lengths is very great awkward, as the heel plate is first pulled forwards and sideways after loosening the nut must be swung out before it is freely displaceable in the longitudinal direction of the ski. After moving lengthways the heel plate has to be secured again

be pivoted that the screw shaft engages in one of the hook-like slot parts. This one Slot parts need to be spaced a certain distance apart is only a limited number of settings the heel cap possible.

The disadvantages of the known water ski bindings are eliminated according to the invention in that the The front end of the heel plate is cranked down and the heel plate in its movable position like a bridge only rests on the ski with its rear end and its front end and that means are provided for pressing down the rear part of the heel plate on the ski, so that after Adjustment of the binding to a certain foot size and depressing the heel plate part lying behind the depressing means rests on the ski, while the part between the depressing means and the front part of the heel plate lying wedge-like from the cranked front end Ski is off.

This allows the heel plate to be attached to the ski in any number of positions so that the binding can be easily adapted to any foot length. When the heel plate is depressed, in the rear of which is frictional engagement between the heel plate and the top of the ski. Of the front raised part of the heel plate acts like a wedge, so that when longitudinal loads occur the heel counter increases the depressive force. Thereby every relative movement is between the ski and the heel plate prevents

The embodiment according to FIGS. 5 and 6 at the bottom against the ski at a predetermined point also has a heel plate II ¹ , which is somewhat similar to the heel plate 11. As a result, the rear part 5 is raised towards its front end, making the heel plate 11, particularly favorable in terms of contact when using it Wedge effect arises, point with the screws 17 up to the rear end, however the plate has a pushed backwards on the upper ski surface, whereby a tapering part 13 ¹ with a longitudinal slot 13 ² , the reaching friction against a relative movement a screw bolt 17 ³ records.

The ribs also serve to loosen the nut of the bolt 17, the same purpose as those according to the first embodiment, even if the nut is not fully tightened, namely making the heel cup more rigid or has been screwed down.

If the heel plate is to be removed together with the heel cap 3 at the rear end of the heel cap 3, as mentioned above, it is as shown in FIG. 4 shows, plate 11 (FIG. 1) a recess 14 is provided, only necessary, the bolts 17 up a certain distance so that the middle part of the heel plate, also because of the. As a result, an additional lifting 45 of the fork-like front part, relatively short of the front part of the heel plate, is possible, whereupon it is possible. With this design, the heel plate, the heel plate together with the cap 3, becomes slightly more flexible. With this training, moving forward and completely removed from the ski, surprisingly good results can be achieved if the toe cap is pushed downwards. In the same simple manner, the 50 gene can be arranged so that each swelling of the ski wood heel plate with the cap 3 reinserted increases the play of the guides. By being. This is a particularly desirable feature of the invention, a binding of which the invention, since sand usually has particular advantage in that it accumulates without the action of the heel plate and the upper ski surface, means disassembled and reassembled that interferes with the operation of the skis.

Binding according to claim 3, characterized in that the length of the heel plate (11) larger from its front end (15) to the rear end of the parallel side edges is than the distance between the rear end of the fastening means (6) for the toe cap (2) and the side guide pin (16) for the heel plate. 5.
