Description

The invention relates to a binding construction for detachable Connecting a shoe to a winter sports device, in particular Ski or snowboard, consisting of at least two binding parts, of which a first binding part in the sole area of the Shoe and a second binding part arranged on the winter sports equipment is, to establish the connection of the on the Winter sports equipment arranged binding part in a recess of the penetrates binding part arranged in the sole area of the shoe, and to establish the connection, the second one on which Winter sports equipment arranged binding part two rotatable, spring-loaded Has receiving elements.

AT 317 737 B shows a ski binding in which the Heel area of the ski boot has a recess and locking elements on the ski supporting housing is provided. The in the longitudinal direction Slidable locking elements are with the help of locking springs biased. The forefoot-side locking element or the heel-side Locking elements engage in locking pans in the recess Ski boot on. The locking elements are used to release the connection by pivoting a release lever into its retracted position Position shifted. In the event of an overload, at least one of the triggers Locking elements and the ski boot are released from the ski.

FR 2 533 448 A1 shows a ski binding in which a ski boot has a recess in the sole, in the locking pans are provided. In the area of the forefoot is an in Ski longitudinal direction linearly movable locking element provided, while a heel-side locking element is provided, which both Slidable in the longitudinal direction of the ski as well as on both sides Link guide pivotally mounted perpendicular to the longitudinal direction of the ski is. The two locking elements are with the help of a coil spring stretched between a heel-side receiving element and a forefoot-side receiving element is provided is. The spring can be preloaded using a screw that the receiving part for the coil spring via a bevel gear connection shifted in the longitudinal direction of the ski, can be adjusted.

A ski safety binding is described in EP 31 570 A1, in the undercuts in a ski boot from the ski side Sole holders can be gripped. The ski boot lies here on the top of a front binding part and on the rear sole holder. The rear part of the housing is open a binding plate movably mounted in the longitudinal direction of the ski, the rear sole holder in the housing part around a ski parallel Transverse axis is pivotally mounted. With a rotary movement and thus when closing or opening the binding Trigger axis both a transverse shift in the longitudinal direction of the ski also a rotating movement around itself. This will be a brake or trigger arm permanently connected to the trigger axis pivoted. There are two sole holders in the forefoot area vertical axes against the tension of a compression spring rotatably mounted. The spring tension can be adjusted using an adjusting screw to be changed. In the event of a lintel fall follows Direction of rotation of one of the two sole holders against the tension of the Spring of the rotating movement of the ski boot and releases when exceeded an adjustable release force releases the ski boot.

In the known embodiments is thus either a recess or a protruding part under the sole of the shoe provided that with the complementary attached to the ski Part should work together, the known constructions this type, however, a symmetrical tripping behavior, in particular in the event of a sudden fall. In addition, the known constructions no interaction between the holding means of the Shoe against an increase, for example in a frontal or Backward fall, and the means to hold against rotation given when a torsional force occurs.

The object of the invention is a new type of binding construction of the type mentioned at the beginning to indicate the one as possible has simple structure and the known disadvantages avoids.

According to the invention, this is achieved in that the receiving elements Independently via spring-loaded actuators are pressurized from each other. As a result, a constructively particularly simple binding construction can be obtained, where it is possible to have a non-linear trip history adjust by the provision of its own actuator for each receiving element, separated on the left and right, from each other can be regulated independently. Since usually the Contact pressure in the heel area is higher than in the toe area, the heel area acts with increased lateral load as a fulcrum, and it is therefore advantageous if the rotatable receiving elements in the toe area of the second binding part are arranged.

An interaction between the holding means of the shoe against an increase in a frontal or a backward fall and the means for stopping rotation upon occurrence of a According to another, torsional force can be brought about Aspect of the invention that the rotatable receiving element has a receiving area that is hemispherical is formed and with a projection of the first, in the sole area the binding part arranged in the shoe interlocks, the protrusion also advantageously round, preferably hemispherical, is formed.

If the second binding part has two rotatable receiving elements, between which a spacer is arranged, and these receiving elements via a spring-loaded trigger resistance element, that according to a further embodiment of the Invention is clasp-shaped and the two receiving elements tries to press on the spacer, are connected, can, by such an arrangement, the binding construction according to the invention by changing the spring pressure on the spring-loaded locking elements act directly in all directions trigger proportionally.

According to a further aspect of the invention, the adjusting devices conveniently clasp-shaped triggering resistance elements exhibit.

A particularly simple construction results if in Heel area a spring-loaded locking element is displaceable, preferably in the longitudinal direction of the ski. This leaves the connection between the first and the second binding part produce particularly easily and with little effort. In other words, that means the spring-loaded Locking element in the direction of the heel area of the first binding part is guided. By a central arrangement of the Binding construction on the winter sports equipment is achieved that in no way influences the bending line of the winter sports equipment becomes. Furthermore, by using a preferably in Ski longitudinal direction slidably guided, spring-loaded locking element the binding construction has a significantly longer return path before triggering what the security aspect of binding construction according to the invention appears not insignificant.

One for easy boarding and for a secure hold particularly favorable embodiment of the binding construction according to the invention can be achieved in that the locking element into a recess in the first, in the sole area of the Shoe arranged binding part engages, it turns out to be has shown particularly favorable when the locking element and / or the recess has at least one inclined surface, which advantageously forms a positive connection.

According to a further embodiment of the invention Binding construction can be provided that the first in Binding part arranged in the sole area of the shoe in the toe and / or Heel area of the shoe on the winter sports equipment facing side is rounded, which improves walking comfort conventional ski boots is increased considerably. Becomes the first binding part of a separate toe part with at least a projection and a separate heel part with a Formed recess, it is particularly simple to conventional Retrofit ski / snowboard boots with the binding part.

The means for releasing the binding construction according to the invention can according to a preferred embodiment according to at least a cable connected to the spring-loaded locking element include, which results in a particularly simple construction.

Fig. 7 is a winter sports device on which a second binding part and several attachments are arranged, and

Fig. 8 shows an attachment part of a winter sports device on which means for releasing a binding structure are arranged.

In the binding construction shown in Fig. 1 is in Sole region of a shoe 5 a first binding part 2, which is in the Toe area 14 and rounded in the heel area 9 is arranged. The first binding part 2 has a recess 31 with a Projection 13 and a recess 8 and engages with one second binding part 3, which is arranged on a winter sports device 6 is into each other. More specifically, grips 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. The recess 8 has in the heel region 9 of the shoe 5 Sloping surfaces 10 on 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, locked. Due to the different lengths and angles of inclination Sloping surfaces 7, 10 make entry easier and easier on the other hand, an undesired loosening of the binding construction 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 ones Binding structures. It is also reduced due to the Friction between shoe 5 and winter sports equipment 6 is a more controllable Triggering process given.

The second binding part 3 shown in FIG. 2 is by means of Screws 19 firmly connected to the winter sports device 6. To the end of the second binding part 3 associated with the toe region 14 this has two receiving elements 11, 11 'with receiving areas 12, 12 ', which are hemispherical. The Receiving elements 11, 11 'are 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 spring-loaded Actuating device 17, 17 ', each a clasp-shaped formed triggering resistance element 16 ', assigned. Due to this arrangement, the tripping characteristic the binding construction 1 changeable and can for example the kanting of the winter sports equipment 6 can be regulated. In that Heel region 9 of the shoe 5 facing the end of the second binding part 3, a spring-loaded locking element 4 is arranged. This spring-loaded locking element 4 is in the longitudinal direction of the Winter sports equipment 6 slidably guided, the pressure of the Spring 18 takes place in the direction of the heel area 9 of the shoe 5. The That is, the second binding part 3 is with the first binding part 2 both positively and non-positively connected, these Connection is almost free of play, which means higher inclinations can be driven. Such binding structures 1 are suitable therefore due to these properties - controllability of the Kantings and driveability at high inclines - particularly good for those in Carving skis dominating the market lately.

A lateral release process of the binding construction according to the invention 1 is shown in FIGS. 3 and 4, wherein Fig. 3 shows the binding construction 1 according to the invention in closed State and Fig. 4 shows the triggering process of such Binding construction 1 shows. 3 is the first binding part 2, which is shown in dashed lines, with the second Binding part 3 connected by the one hand the projections 13, 13 'of the first binding part 2 in receiving areas 12, 12' the receiving elements 11, 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. The protective plates protected in this way are located under the cover plate 20. clasp-shaped triggering resistance elements 16, 16 ' the one hand the receiving elements 11, 11 'to the spacer element Press 15 and on the other hand an independent setting enable the triggering forces via the adjusting devices 17, 17 '.

In Fig. 4, the binding structure 1 is on the side, in this Fall to the left, solved. The spring 18, which is the Locking element 4 loaded, compressed, so that the spring-loaded Locking element 4 to the center of the second binding part 3 can move, whereby between the receiving areas 12, 12 ' of the second binding part 3 and the projections 13, 13 'of first binding part 2, a small margin arises. by virtue of the pressure which the first binding part 2 experiences in the direction of the arrow P, becomes the receiving element 11 'due to its engagement with the projection 13 'rotated in the printing direction. simultaneously The projection 13 slides easily due to the small margin from the receiving area 12 of the receiving element 11 via the Inclined surface of the spacer 15, so that the positive connection between the projections 13, 13 'and the receiving elements 11, 11 'is released and the first binding part 2 from the second binding part 3 is separated. So it is through a change the spring pressure of the rear spring bolt is directly proportional Triggering possible in all directions. In addition, you can the triggering forces on the left and right via the adjusting devices 17, 17 'or the clasp-shaped triggering resistance elements 16 'can be set separately, so that the triggering 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 over 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 part 3 is connected. The lever 21 that Joint 22 and at least part of the guide part 24 for that Rope 23 are in an attachment part 25 adapted to the shape of the shoe is mounted in front of the shoe 5 on the winter sports device 6. Now the lever 21 in the direction of arrow P with pressure, for example by means of a ski pole, the moves Lever 21 towards winter sports device 6 and pulls over joint 22 the rope 23 and then the spring bolt 29 in the direction of the arrow P1 towards the toe area of the shoe 5, so that the spring-loaded Locking element 4 no longer or no longer free of play in the Recess 8 of the first binding part 2 engages and loosening the connection is easily possible. It goes without saying that an arrangement of at least parts of the means 21, 22, 23, 24 to release the binding construction 1 in a behind the heel area the shoe 5 arranged attachment part of the winter sports equipment 6 is also possible and fulfills the purpose.

The shoe 5 shown in Fig. 6 is for engagement in a Binding construction 1 according to the invention 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), with a projection in the recess 31 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 its toe area 14 and its heel area 9 rounded, resulting in a significant increase in Contributes to walking comfort. 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 that the retrofitting is already Ski boots in circulation with the first binding part 2 to facilitate.

On the winter sports device 6 shown in Fig. 7 is approximately in the middle a second binding part 3, which is a spring-loaded Locking element 4 for releasable connection to a first binding part 2 (not shown). In addition are before and adapted behind the second binding part 3 of the shoe shape Attachment parts 25 arranged on the winter sports device 6. On these attachment parts 25 is a damping device 27 articulated acts between the attachment parts 25 and 25 '. The attachment parts 25, 25 'are at their opposite the damping device 3 End area with retaining screws 26 firmly with the winter sports equipment 6 connected. Magnetic elements are on the top parts 25 ' 30 for slidingly connecting the attachment parts 25 'arranged with the winter sports equipment 6. If the winter sports equipment 6 is pressurized in the direction of arrow P, move the attachment parts 25 'and 25 to each other, the impact pressure is absorbed by the damping device 27. An additional Damping takes place through the magnetic elements 30, which are slidable Moving the attachment parts 25 'to the center of the winter sports device 6 enable. The adapted to the shape of the shoe Top parts 25 thus perform 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 close the second binding part 3 protect.

8 shows that means 21, 22, 23, 24 for actuating a spring-loaded locking element 4 (not shown) articulated 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 out and causes via the joint 22 that the guide part 24 and the rope 23 are moved in the direction of arrow B. Furthermore, on the side of the attachment part facing away from the shoe 25 a separate damping unit 28 of a damping device 27 hinged.

If the invention with reference to the above-described embodiments has been explained, it goes without saying that Modifications and means that are suitable, the inventive idea implement, are conceivable and are well within the scope of the invention. For example, at least the part of the heel area, in which the recess is arranged, height adjustable be so that the horizontal position of the shoe is changeable and so a template of the shoe is adjustable. Another embodiment provides for at least the part of the heel area in which the recess is arranged to be resilient in the horizontal direction store, so the damping properties of the invention To improve binding construction.

A combination of these features, i.e. 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.
