According to a further aspect of the invention, the adjusting devices Conveniently spangenförmig trained release resistor elements exhibit.

A particularly simple construction results when in the Heel region displaceable a spring-loaded locking element, preferably in the ski longitudinal direction, is guided. This leaves the connection between the first and the second binding part Produce particularly easily and with little effort. In other words, that means that the spring-loaded Locking element in the direction of the heel region of the first binding member slidably guided. By a central arrangement of Binding construction on the winter sports equipment is achieved that the flex line of the winter sports equipment in no way influenced becomes. Furthermore, by using a preferably in Ski longitudinally slidably guided spring-loaded locking element the binding construction a much longer Rückstellweg before the release, what the security aspect of binding structure according to the invention does not seem insignificant.

One for easy entry and for a secure fit particularly favorable embodiment of the binding construction according to the invention can be achieved in that the locking element in a recess of the first, in the sole area of the Shoe arranged binding part snaps into place, it being as has been found particularly favorable when the locking element and / or the recess have at least one inclined surface, which advantageously forms a positive connection.

In the binding construction shown in Fig. 1 is in Sole region of a shoe 5, a first binding part 2, in the Toe area 14 and rounded in the heel area 9, arranged. The first binding part 2 has a recess 31 with a Projection 13 and a recess 8 and engages with a second binding part 3, which is arranged on a winter sports device 6 is, in each other. More specifically, in the toe area 14 the projection 13 of the first binding part 2 in a receiving area 12 of the receiving element 11 of the second binding part. 3 on. In the heel region 9 of the shoe 5, the recess 8 Sloping surfaces 10, the different lengths and angles of inclination exhibit. In this recess 8 is the spring-loaded Locking element 4, which also has inclined surfaces 7, engaged. Due to the different lengths and inclination angle of the Beveled surfaces 7, 10 on the one hand the entry is facilitated and on the other hand, an undesired loosening of the binding structure 1 prevented. Such a binding construction 1 has less mechanical parts on than the conventional bindings and is therefore not least because of a now not necessary Binding plate overall much lighter than conventional Binding structures. Moreover, due to the reduced Friction between shoe 5 and winter sports equipment 6 a controllierbarer Tripping process given.

The illustrated in Fig. 2 second binding member 3 is by means of Screws 19 firmly connected to the winter sports equipment 6. To the the toe area 14 associated end of the second binding part. 3 this has two receiving elements 11, 11 'with receiving areas 12, 12 ', which are hemispherical in shape, on. The Receiving elements 11, 11 'are a spring-loaded, clasp-shaped trained trigger resistance element 16 with each other connected and are pressed by this against the spacer 15. In addition, each receiving element 11, 11 'is a spring-loaded Actuator 17, 17 ', each a clasp-shaped having a trained tripping resistance element 16 ', assigned. By this arrangement, the tripping characteristic the binding structure 1 changeable and can, for example the canting of winter sports equipment 6 are regulated. In the Heel region 9 of the shoe 5 facing the end of the second binding member 3, a spring-loaded locking element 4 is arranged. This spring-loaded locking element 4 is in the longitudinal direction of Winter sports equipment 6 slidably guided, the pressure of the Spring 18 takes place in the direction of the heel region 9 of the shoe 5. The means, the second binding part 3 is connected to the first binding part 2 positively and non-positively connected, these Connection occurs almost without play, resulting in higher inclinations can be driven. Such binding structures 1 are suitable Therefore, due to these characteristics - adjustability of the Kantings and driveability of high slopes - especially good for in Recently, the market dominated carving skis.

A lateral triggering operation of the binding construction according to the invention 1 is shown in Figs. 3 and 4, wherein Fig. 3, the binding structure 1 of the invention in a closed State and Fig. 4 shows the triggering operation of such Binding construction 1 shows. In Fig. 3, the first binding part 2, which is shown in dashed lines, with the second Binding part 3 connected by, on the one hand, the projections 13, 13 'of the first binding part 2 in receiving areas 12, 12' the receiving elements 1 1, 11 'of the second binding part. 2 engage and on the other hand, the spring-loaded locking element 4 in a recess 8 of the first binding part 2 is engaged. Under the cover plate 20 are protected in this way, clasp-shaped triggering resistance elements 16, 16 ' on the one hand the receiving elements 11, 11 'to the spacer element Press 15 and on the other hand, an independent setting the release forces on the adjusting devices 17, 17 'allow.

In Fig. 4, the binding structure 1 is laterally, in this Case to the left, solved. In this case, the spring 18, which is the Locking element 4 loaded, compressed, so that the spring-loaded Latching element 4 to the center of the second binding member. 3 can move, whereby between the receiving areas 12, 12 ' of the second binding part 3 and the projections 13, 13 'of the first binding part 2 a small margin arises. by virtue of the pressure experienced by the first binding part 2 in the direction of arrow P, becomes the receiving element 11 'due to his intervention rotated with the projection 13 'in the printing direction. simultaneously slides the projection 13 due to the small margin easily from the receiving area 12 of the receiving element 11 via the Inclined surface of the spacer element 15, so that the positive connection between the projections 13, 13 'and the receiving elements 11, 11 'is dissolved and the first binding part 2 from the second binding part 3 is disconnected. So it's going to be a change the spring pressure of the rear spring bolt a directly proportional Triggering in all directions allows. In addition, you can the release forces left and right over the actuators 17, 17 'and the clasp-shaped triggering resistance elements 16 'are set separately, so that the tripping characteristic of the binding construction according to the invention 1 is changeable overall.

The means 21, 22, 23, 24 shown in Fig. 5 for releasing the Binding construction 1 comprise a lever 21, which via a Joint 22 with a guide member 24 in which a rope 23 or similar is arranged, this rope 23 with the spring bolt 29 of the second binding member 3 is connected. The lever 21, the Joint 22 and at least a portion of the guide member 24 for the Rope 23 are in a shoe shape adapted attachment part 25, the is mounted in front of the shoe 5 on the winter sports equipment 6, arranged. Now, the lever 21 in the direction of arrow P with pressure, for example by means of a ski pole, acted upon, the moves Lever 21 to winter sports equipment 6 and pulls over the joint 22nd the cable 23 and subsequently the spring pin 29 in the arrow direction P1 towards the toe area of the shoe 5, leaving the spring-loaded Locking element 4 no longer or no longer play in the Recess 8 of the first binding member 2 engages and a release the connection is easily possible. It goes without saying in that an arrangement of at least parts of the means 21, 22, 23, 24 for releasing the binding construction 1 in a behind the heel area of the shoe 5 arranged attachment of the winter sports equipment 6 is also possible and Zweckerfüllend.

The shoe 5 shown in Fig. 6 is for engaging in a inventive binding construction 1 is formed and has in his sole area a first binding part 2 with a recess 31 for detachably receiving a second binding part 3 (not shown), wherein in the recess 31, a projection 13 and a recess 8 for positive and non-positive connection are arranged with the second binding part 3. Furthermore, the first binding part 2 in his toe area 14 and his heel area 9 rounded off, resulting in a substantial increase in the Walking comfort contributes. It is also quite conceivable that the first binding part 2 of a separate toe part 14 with at least a projection 13 and a separate heel part 9 with a recess 8 is formed so as to retrofit already circulating ski boots with the first binding part 2 to facilitate.

On the winter sports device 6 shown in Fig. 7 is about in the middle a second binding part 3, which is a spring-loaded Locking element 4 for releasably connecting to a first binding part 2 (not shown). Additionally are available and adapted behind the second binding part 3 of the shoe shape Attachment 25 arranged on winter sports equipment 6. At these attachment parts 25, a damping device 27 is articulated, the between the attachment parts 25 and 25 'acts. The attachment parts 25,25 'are opposite to the damping device 3 at their End area by means of retaining screws 26 firmly with the winter sports equipment 6 connected. On the attachment parts 25 'are magnetic elements 30 for slidably connecting the attachment parts 25 'arranged with the winter sports equipment 6. If the winter sports equipment 6 in the direction of arrow P is pressurized, move the attachment parts 25 'and 25 to each other, the impact pressure is absorbed by the damping device 27. An additional Damping is done by the magnetic elements 30, which is a slidable Moving the attachment parts 25 'to the center of the winter sports equipment 6 back. The shoe shape adapted Attachment parts 25 thus fulfill two functions, namely on the one hand as part of a damping device and on the other hand as Snow and dirt deflector, so as to the second binding part 3 to protect.

8 shows that on the attachment part 25 means 21, 22, 23, 24 for actuating a spring-loaded locking element 4 (not shown) hinged cable are arranged. Will the lever 21 in the direction of arrow A, for example by means of a ski pole pressurized, the lever 21 moves to the winter sports equipment 6 and causes via the joint 22 that the guide part 24 and the cable 23 are moved in the direction of arrow B. Furthermore, on the side facing away from the shoe of the attachment part 25 a separate damping unit 28 of a damping device 27th hinged.

Although the invention with reference to the above embodiments It goes without saying that Modifications and means that are suitable to the inventive idea implement, are conceivable and quite within the scope of the invention. For example, at least the part of the heel area, in the recess is arranged, designed height adjustable be so that the horizontal position of the shoe changeable and so a template of the shoe is adjustable. Another embodiment provides, at least the part of the heel area in which the recess is arranged in the horizontal direction resiliently store, so as to the damping properties of the invention Improve binding construction.

Also a combination of these features, so a spring-loaded, height adjustable part of the heel area, in which the Recess for receiving the spring-loaded locking element arranged is, is quite conceivable.
