Description

The invention relates to a shoe holding unit of a ski or snowboard binding with at least one shoe holding element, a return spring for the shoe holding member and a damping device for receiving short, hard shocks. The at least one shoe-holding unit and the damping device are connected via a transmission mechanism which translates a small deflection of the at least one shoe-holding element into a larger movement on the damping device.

It is known that the triggering force for a ski or snowboard binding can be set so that the safety binding triggers reliably in the event of a fall. A fall can be compared to a relatively slow bump, relatively slow to bumps, which can occur, for example, when driving over smaller bumps. Such short, hard impacts can lead to false tripping of the safety binding and thereby to the fall of the skier or snowboarder. Therefore, safety bindings with damping devices have been developed, wherein the damping devices dampen the short, hard impacts to such an extent that less false triggering of the safety bond occurs.

For example, the beats EP 0 829 280 B1 a damping device for a shoe holding unit consisting of a cylinder filled with a pasty at rest hydraulic medium. The short hard impacts are transmitted directly from the shoe holding unit to the damping device.

It is therefore an object to provide a safety binding with at least one shoe holding unit, a toe holder or a heel holder, in which the risk of false triggering by short, hard shocks is further reduced.

This object is solved by the subject matter of claim 1. Further embodiments of the invention are the subject of the dependent claims. These can be technological meaningfully combined with each other. The description, in particular in conjunction with the drawing, additionally characterizes and specifies the invention.

One embodiment relates to a shoe holding unit of a ski or snowboard binding, comprising at least one shoe retaining element, a return spring for the shoe holding element, a damping device for receiving short, hard shocks, wherein the at least one shoe holding unit and the damping device are connected via a translation mechanism, which is a small movement of the translates at least one shoe retaining element into a larger movement on the damping device.

The shoe-holding unit may be a toe-holder or heel-holder of a safety binding for a ski or a snowboard. The return spring is the spring which presses the shoe holding unit or at least one shoe holding element against the ski or snowboard shoe to firmly connect the ski or snowboard shoe with the respective sports equipment. Against the resistance of the return spring of the ski or snowboard shoe from the binding to the toe or heel side can be removed. The force with which the return spring acts can be adjusted to a body weight and the sporting abilities of the skier or snowboarder.

A small deflection of the shoe holding unit or one of the shoe holding elements is transmitted through the translation mechanism to the damping device. One end of the transmission element acts directly or indirectly together with the at least one shoe holding element, while the other end acts on the damping device. The translation mechanism is constructed, for example, as a lever connection, that the small deflection of the shoe holding member is translated into a larger movement of the damping device, resulting in an effective damping of short, hard shocks acting on the shoe holding member. In this case, the deflection of the shoe holding unit can be measured, for example, in degrees, while the damping movement in mm can be measured.

The damping device only works with short punches because it has a shorter reaction time than the return spring. This means that when a shock or a force transversely or obliquely to the direction of travel, which acts on the ski holding member, this force simultaneously on the Return spring and the damping device is transmitted. If the force suddenly occurs, this is absorbed by the damping device and the return spring is compressed less than would be expected due to the strength of the force occurring. This prevents that despite the action of a force on the release force for the return spring, the shoe holding element triggers and crashes the skier or snowboarder.

On the other hand, if the force acts on the return spring and damping device at a "normal speed", then the return spring will be compressed in accordance with the force acting on it, while at the same time the damping device will be moved without unfolding any appreciable damping action. The shoe holding element can now trigger.

In the translation mechanism may be a translation mechanism that transmits a force acting on the at least one shoe holding member force that causes the deflection, at least one lever on a damper of the damping device and thereby amplified. A well-known translation mechanism is the lever, which is rotatable about a fulcrum and due to the different lever lengths before and after the fulcrum, a force acting on one end can translate into a larger force on the other end of the lever. The lever may be formed in one piece or comprise two lever sections connected by means of a joint.

In this case, the lever may have a first lever portion which is coupled to the at least one shoe holding member, and a second lever portion which is coupled to the damper. Both lever sections can be pivotable in a pivot joint about a common pivot point.

The damping device is preferably reset by the return spring for the shoe holding member from an activated state to the idle state. That is, the return spring, which is also elastically compressed in the short strokes, at the same time, when it is stretched to the length before the occurrence of the short hard stroke, simultaneously returns the damper device to the initial position before the occurrence of the short hard stroke. The force implemented by the compression in the return spring thus simultaneously causes the provision of the shoe holding member and a provision of the damping device. The latter can cause the return spring only when the damping device is mechanically coupled to the at least one shoe holding member so that a return movement of the shoe holding member by the return spring inevitably acts on the damping device. Such a mechanical coupling may, for example, be a linkage in which the individual rods are fixedly connected to one another in, for example, pivot joints. The first rod can be firmly connected to the shoe holding member and the last rod fixed to the damper.

Alternatively, the damper and the shoe holding member (s) may also be connected by a mechanism which, when at rest, only abuts the damper and / or the shoe-holding member without having a firm connection. In this case, the return spring after a deflection, only the shoe holding elements and possibly a part of the mechanism back to the idle state, while the damper returns separately to the idle state, possibly taking a part of the mechanics.

The return spring may be arranged transversely to or along a longitudinal axis of the ski or snowboard binding depending on the construction of the shoe holding unit. The longitudinal axis of the ski binding always coincides with a longitudinal axis of the ski and points in the direction of travel. When snowboard, however, there are different ways to attach the ski bindings on the board, the longitudinal axis of the snowboard binding is usually not identical to the direction of travel of the snowboard.

The at least one shoe holding unit can be connected in a further embodiment directly with the transmission mechanism in, for example, a pivot joint, in which the shoe holding member can be pivoted relative to the translation mechanism. The swivel joint forming ends of the shoe holding unit and the translation mechanism have a common pivot axis, for example in the form of a tube, so that the hinge connection can transmit tensile and compressive forces in a simultaneous pivoting of the shoe holding unit and / or the translation mechanism.

The at least one shoe retaining element can also be connected via a link with the translation mechanism. That is, the shoe holding member acts, for example to a part of a guide sleeve for the return spring, which has on its applied by the shoe holding member side a slotted guide for the transmission mechanism and / or is connected to the translation mechanism in a, for example, pivot joint.

The guide sleeve of the return spring may consist of two separate sub-sleeves, which are spaced apart from each other in the rest state of the return spring. If the at least one shoe holding element is now deflected, then the two sleeve parts are moved toward one another, that is to say that the distance between the opposite sleeve part ends is reduced.

Although the sleeve is referred to herein as a guide sleeve, the sleeve at the same time has the task of the spring to specify a maximum extent and maximum compression. That is, when the two opposite part sleeve ends abut each other touching each other, the return spring is compressed maximum. If the expanding sleeve spring clamps the at least one shoe holding element firmly against the ski or snowboard shoe, it is maximally extended.

In order to guarantee a secure parallel guidance of the two sub-sleeves, one of the sub-sleeves, for example, centrally over the end of the sub-sleeve in the direction of the other sub-sleeve projecting guide pins, which guided in a formed on or in the other sub-sleeve hollow cylinder during compression and expansion of the return spring becomes. Alternatively, the one of the sub-sleeves on or in the inside or the outside of a groove, the other of the sub-sleeves have a guide element which is adapted to the shape of the groove and is guided in this.

The damping device as a whole or at least one damper of the damping device can be arranged transversely to or along a longitudinal axis of the ski or snowboard binding. In this case, at least a part of a damper housing firmly connected to the ski or snowboard, so that it can not move linearly relative to the ski or snowboard. The connection may be a pivot joint, in which the damper or at least a part of the damper housing can be pivoted about a fixed pivot axis.

The damper may be a cylinder with a piston at least partially filled with a damping means. In this case, the transmission mechanism can act on the cylinder or on the piston, so that the piston is pressed in a deflection of the shoe holding member in the cylinder. The damping means in a single-chamber cylinder or two-chamber cylinder is thereby compressed and / or displaced and thereby causes a damping of the force acting on the shoe retaining element or the return spring force. The damping means can be, for example, a compressible liquid, for example a hydraulic oil, for example a compressible gas or, for example, a compressible pasty flow agent.

The cylindrical damper can be seen in the longitudinal direction of the ski or snowboard binding arranged in front of the return spring. In this embodiment, the return spring can be arranged transversely to the longitudinal direction of the ski or snowboard binding, for example between the two shoe holding elements of a toe holder, while the damper is arranged longitudinally to the binding and, for example, connected to the ski in a pivot joint which is transverse to Bond centrally located between the two shoe holding elements of the toe holder.

In an alternative embodiment, the return spring may surround the cylinder. In this case, the return spring and the damper for binding must be arranged the same relative to the ski or snowboard binding, that is, both in the longitudinal direction or both in the transverse direction.

The damping device may comprise a damper in the form of a mass pendulum in another embodiment. That is, a deflection of the at least one shoe holding element causes a deflection of a mass pendulum from a rest position. As soon as the force that causes the deflection of the at least one shoe retaining element causes or is eliminated, the mass pendulum can be forced back into the resting state by the retaining spring or, alternatively, return to the idle state independently of the return spring.

In a further embodiment of the invention, the damping device may comprise a damper in the form of a damper rubber. The damper rubber is compressed to generate the damping force and can elastically expand to its original shape after the end of the force. The damper rubber can, as already described above generally for the damper, be arranged along a longitudinal axis of the binding or transversely thereto. To compress the damper rubber may serve a scissors-like transmission mechanism, with two scissor elements, which are connected together in a pivot joint. The hinge divides each of the scissor elements into a shorter and a longer section, the shorter section being coupled to the shoe-holding members, while the longer ends compress the cushioning rubber. This achieves the desired translation effect.

Instead of an elastically deformable solid body, the compressible body may also have an elastic outer skin filled with a compressible agent. The compressible body may be formed from a single material or from two or more bonded layers of different elastically deformable materials.

The damper rubber may also, as already described for the damping cylinder, be surrounded by the return spring. This applies both in the event that the return spring along the longitudinal axis or transverse to the longitudinal axis of the ski or snowboard binding is arranged.

The damper rubber or the damping cylinder can be surrounded by a part of the return spring especially at a return spring arranged between the two shoe holding elements of a toe holder. Thus, they can be arranged only in one of the two surrounding the return spring sub-sleeves, while the other sub-sleeve has the connection means, which may also be surrounded by the return spring and the deflection of the at least one shoe holding member translated to the damping device. It does not matter if a toe holder, whether the shoe holding member acts directly on the connecting device or on the damper, in both cases it comes to the same attenuation short, hard shocks, so that an unwanted release of the respective shoe holding member is prevented.

All described damper devices are adapted to receive a force acting on the at least one shoe retaining element, here a short hard shock, to amplify this force via a mechanism, so acting on the damper a higher force than at least one shoe holding element. As a result, the damper reacts in principle faster to the return spring on the force acting on the shoe holding member and thereby sets the force acting on the shoe holding element force quickly counteracting a counterforce in the form of damping, which prevents the return spring is acted upon by a force which causes a deflection of the shoe holding member would effect. As a result, a release of the at least one shoe holding element is more reliably avoided than in shoe holding units with a cushioning but without a corresponding translation mechanism.

In a slow impact, for example, a fall, however, the shoe holding member is not prevented by the damping to trigger.

For the entire description and claims, the term "a" is used as an indefinite article and the number of parts is not limited to a single one. Should "a" have the meaning of "only one", it will be understood by those skilled in the context, or will be unambiguously disclosed by the use of appropriate terms, such as "a single".

Shoe holding unit with two shoe holding elements and arranged therebetween return spring and parallel damper

The FIG. 1 shows a first embodiment of a shoe holding unit 1 according to the invention for a ski or snowboard shoe, here a toe holder. The shoe holding unit 1 has two shoe holding elements 2, 3 and a return spring 4 arranged between the shoe holding elements 2, 3. The return spring 4 is caught in two sub-sleeves 5, 6, which determine a maximum extent of the return spring 4 and a maximum compression of the return spring 4. The maximum possible compression of the return spring is achieved when the two opposite ends 5a, 6a of the two sub-sleeves 5, 6 touch. The maximum extent of the return spring 4 is reached when the two other ends 5 b, 6 b of the sub-sleeves 4, 5, the shoe holding elements 2, 3 in the in the FIG. 1 hold position shown.

In the embodiment shown, the shoe holding elements 2, 3 at one end of extensions 2a, 3a, which are each connected to a pivot joint 7, 8 with a translation mechanism 9. The translation mechanism 9 consists of two transmission elements 9 a, 9 b and is connected in a further pivot joint 10 with a damper 11. The translation mechanism 9 can transmit a force acting on the shoe holding member 2, 3 force on the damper 11 and thereby reinforce.

The damper 11 consists of a damper housing 12 and a damping piston 13, which can be moved into and out of the damper housing and out, and which is pivotably connected in a further pivot joint 14 to the ski or snowboard. At rest the pivot joints 10 and 14 lie on a common straight line, which is equidistant from the two sub-sleeve ends 5a, 6a and the two shoe holding elements 2, 3, that is, a center line of the shoe holding unit 1.

In the FIG. 2 is the shoe holding unit of FIG. 1 shown, wherein the shoe holding member 3 has been deflected by a force substantially transverse to the direction of travel. Due to the deflection of the shoe holding element 3, not only the restoring spring 4 is partially compressed via the partial sleeve 6, but at the same time the transmission element 9b connected to the extension 3a is pivoted in the pivot joint 10. Since the damper 11 can not escape, the damper piston 13 is pressed into the damper housing 12 and compresses a contained in the damper 11 compressible damping means. It comes in addition to a pivoting of the damper 11 in the pivot joint 14, since the freedom of movement of the damper 11 relative to the ski essentially by the four pivot joints 7, 8, 10 14 is specified.

Now acts no more force on the shoe holding member 3, this is returned from the return spring 4 in the in the FIG. 1 shown rest position pressed. Since the damper 11 via the transmission mechanism 9 mechanically fixed to the shoe holding elements 2, 3, together with the shoe holding member 3, the damping device is again in the in the FIG. 1 forced rest position forced.

The FIGS. 3 and 4 show an alternative embodiment of the shoe holding unit 1 of FIG. 1 , The main difference is that in the embodiment of the FIG. 3 the shoe holding elements 2, 3 have no extensions, and the shoe holding elements 2, 3 are not directly but via the sub-sleeves 5, 6 coupled to the damper 11.

The sub-sleeves 5, 6 have on their side facing away from the shoe retaining element on a sliding guide for the respective transmission element 9a, 9b. In this case, the transmission elements 9a, 9b can be guided along the slide and pivoted about pivot axes 7, 8, 10. If now one of the sub-sleeves 5, 6 is pressed by the corresponding shoe holding element 2, 3 in the direction of the other sub-sleeve 5, 6, as shown in the FIG. 4 can be seen, the damper 11 is activated via the pivot joints 15 and the pivot joint 14.

The FIGS. 5 and 6 show a further embodiment in which a mass pendulum 17 forms the damper. The mass pendulum 17 is different than the previously shown damper 11 in two pivot joints 18, 19 with the transmission mechanism 9 and the transmission elements 9a, 9b is connected. The articulation of the transmission elements 9a, 9b in the pivot joints 7, 8, as shown on the sub-sleeves 5, 6 or as shown in Figures 1 and 2 known, directly through the shoe holding elements 2, 3 and the possible extensions 2a, 3a of the shoe holding elements 2, 3 take place. The mass pendulum 17 is not fixedly connected to the ski or snowboard at one point, but can be guided in a guide, for example in a guide rail, so that it can stand out from or be pressed against the ski / snowboard surface. Also in this embodiment, a force acting on the shoe holding member 2, 3 force is transmitted from the translation mechanism 9 on the mass pendulum 17 and thereby amplified. Due to the greater force acting on the mass pendulum 17, a damping force is generated early on, which counteracts a compression of the return spring 4 and thereby prevents the shoe holding element 2, 3 triggers in short hard shocks.

The FIGS. 7 and 8 shows a further embodiment in which the return spring 20 surrounds the damper 11 and connects the damper housing 12 and the transmission mechanism 9 with the damper piston 13 connected to the ski or snowboard in the pivot joints 14. Unlike the previously shown embodiments, the damper 11 and the return spring 20 act here in the same direction, namely in the longitudinal direction of the ski or snowboard binding. The advantages of damping are the same as already described for the preceding figures.

In this embodiment, additionally, the return spring 4 between the sub-sleeves 5, 6 may be arranged. The entire spring resistance against deflection of the shoe holding elements 2, 3 is then applied together from the two return springs 4, 20, that is, the individual spring 4, 20 may be designed weaker.

The FIG. 9 shows a sketch of another embodiment of a shoe holding unit 1 with a damping. The damper 21 is this time formed as an elastically deformable solid body of a scissors mechanism 22, in the example shown by the sub-sleeves 5, the sixth is controlled, can be compressed. The scissors mechanism 22 has a scissors joint 16, by a lever translation of the movement, for example, of the sub-sleeves 5, 6 is effected on the damper 21. The shoe holding unit 1 has a return spring 4 between the two sub-sleeves 5, 6.

In this embodiment, when the ends of the scissor mechanism 22 connected to the two sub-sleeves 5, 6 are moved towards each other, the other end of the scissor mechanism 22 closes by a greater distance, ie a greater force acts on the damper than on the sub-sleeves 5, 6 As a result, the desired early damping of the force acting on the shoe holding element 2, 3 force is effected, which prevents a triggering of the shoe holding member 2, 3 due to short hard impacts.

The FIG. 10 Finally, shows an embodiment in which the damper 23, the transmission mechanism 24 and the return spring 4 between or partially in the sub-sleeves 5, 6 are arranged, wherein the return spring 4, the damper 23 completely and the transmission mechanism 24 partially surrounds. The translation mechanism 24 has on its part of the sleeve 5 side facing a shoulder 25, with a diameter which substantially corresponds to the outer diameter of the return spring 4. Thereby, a force acting on the shoe holding member 5 is transmitted simultaneously to the return spring and the damper 23. The damper 23 may, for example, as from the FIGS. 1 to 4 and 9 be known, that is, a damper housing and a damper piston or be an elastic deformable solid body.

Return spring 4 and damper 23 are in the embodiment of FIG. 10 aligned transversely to the longitudinal direction of the ski or snowboard binding and run parallel to each other. The damper assembly in the FIG. 10 has a very compact design, with few interconnected parts. As a result, for example, a toe holder with damping can be built very short, for example, as short as he would have no damping.

Although a possible embodiment of the improvement has been disclosed in the foregoing description, it should be understood that numerous other variants of embodiments by combination possibilities of all mentioned and further all the Persons skilled in obvious technical features and embodiments exist. It is further understood that the embodiment is to be understood as an example only, which does not limit the scope, applicability, and configuration in any way. Rather, the foregoing description would suggest a suitable way for the skilled person to realize at least one exemplary embodiment. It should be understood that in an exemplary embodiment, numerous changes in the function and arrangement of the elements may be made without departing from the scope and equivalents disclosed in the claims.
