    专利说明:

    The invention relates to a ski binding for holding a ski boot on a ski, which has two jaws which are each pivotable about a jaw pivot point and each having a gripper arbor, wherein the jaws each have spaced and to the jaw fulcrums spaced holding fulcrums.
    The invention particularly relates to a toe for a touring ski binding. In the field of bindings for touring skiing, the invention mainly relates to so-called lightweight touring ski bindings, which are also referred to as pin bindings. In the case of such pin bindings, pin-shaped ski binding parts such as pliers engage directly in adaptations provided on the ski boot tip, so that it is possible to dispense with weight-relevant parts such as frame, linkage or plate and also the locking mechanism required for this purpose.
    These weight advantages is offset by the disadvantage that a ski climber who ascends with a pin binding must completely block the safety release mechanism by hand. If he does not block the safety mechanism as he climbs, the trigger mechanism could trigger unintentionally at each step. Before descending, the ski mountaineer must remember that the trigger function is blocked and unlock the lock manually. If he forgets this and falls down, he risks serious injury as it can not be separated from the ski due to the locked release mechanism.
    The invention is based on the object of further developing such ski bindings.
    This object is achieved in a generic ski binding in that the holding fulcrums are connected to each other via a crossbar.
    This causes the jaws are not moved independently, but a movement of a jaw inevitably has a movement of the other jaw result. This makes it possible to form the ski binding in such a way that a shoe held in the ski binding can have a certain play of movement without it detaching itself from the binding. Only when a predetermined game exceeds the cheeks release the ski boot.
    In order to make this possible, it is advantageous if the traverse is displaceable on a line connecting the holding fulcrums. The traverse is thus, for example, relative to a base plate or the ski on which the ski binding is arranged, displaced. At fixed jaw fulcrums, such a displacement on a line between the fulcrums leads to a displacement of the jaw position and thus a movement of the ski boot held in the ski binding.
    To keep a ski boot firmly but rotatably on the ski binding and in particular on the jaws, it is proposed that the jaws have a holding arm which extends from the jaw pivot to the holding fulcrum, and a gripper arm which extends from the jaw pivot to the gripper arbor , This makes it possible to hold a ski boot between two gripper pins of the two jaws by inserting the gripper pins into corresponding recesses on the ski boot tip.
    In an advantageous embodiment, the distance between the jaw pivot and gripper mandrel is at 1.8 to 2.2 times the distance between the jaw pivot and holding fulcrum and the distance between the jaw fulcrums corresponds to 1.1 to 1.3 times the distance between the fulcrums. These proportions allow a mechanically simple structure with optimal function.
    In order to facilitate a connection between jaw and in particular gripper pinion and ski boot and also a release of the ski boot from the binding, it is proposed that the jaws have a distance from the jaw pivot spacer. This spacer may preferably have a cam surface, which is preferably a circular segment portion with a center spaced from the jaw center and may be connected to the jaw.
    In order to facilitate opening of the ski binding, it is proposed that the traverse has two crossbeams connected to each other via a crossbeam. This makes it possible to buckle the crossbar and thereby reduce the distance between the holding fulcrums, thereby moving the ends of the jaws against which gripper pins can be placed.
    A joint makes the transmission of a thrust difficult in the direction of the traverse. It is therefore proposed that the crossbeam arms are arranged between the support fulcrums so that they can transmit a thrust force with a component transverse to the line of the support fulcrums.
    A simple way to realize this is that the truss arms next to the crossbar joint have a contact surface. However, the truss joint could also, for example, latching predetermined positions that hold the truss arms in a special orientation to each other.
    In order to move the truss arms controlled, it is proposed that the truss joint has a cam guided in a control cam. In this case, either the cam or the cam can be part of the traverse.
    In particular, to ensure a symmetrical position of the jaws relative to each other and to a ski boot, it is proposed that the control cam has a V-shaped cam surface area. The guided in this area cam is preferably pressed into the notch, creating a stable position.
    In addition, other areas of the cam can also define additional stable areas.
    An advantageous embodiment provides that the control cam is arranged on a bolt which is displaceable only in one direction transverse to a line connecting the jaw fulcrums. This preferably movable in the ski direction latch holds the cam and acts against the cam and makes it possible to cause buckling of the traverse or avoid.
    It is advantageous if the bolt is displaceable against the force of a spring, which acts on the one hand on the movable latch and on the other hand to a stationary system. The fixed installation may be a base plate of the ski binding or a directly attached to the ski element. A spring arranged in this way thus makes it possible to set the release force of the ski binding in a defined manner via the spring force.
    As varies depending on the design of Greiferdornen and recordings in the ski boot, the distance between the Greiferdornen in their holding position, a device is proposed which compensates for this game. For this purpose, the traverse on two truss arms which are pivotally connected to each other via a run in a slot cam, wherein on a truss arm, a control cam and on the other truss arm a cam surface is arranged, which cooperate with each other. A movement of the retaining cam towards the tip of the ski thereby moves the retaining pins towards each other while the control cam slides over the cam surface. The cam surface presses the crossbar arms even further apart, so that the retaining thorns are moved further towards each other until the crossbar arms are aligned approximately on a line.
    It is advantageous if the support fulcrum of the truss arm of the cam surface is arranged eccentrically to the cam surface so that he slowly pushes the truss arms apart.
    To first hold the ski boot with a lateral displacement of the jaws and then actively pull the pin from the recording on the ski boot, it is proposed that the jaws have a contact surface which cooperates with a counter surface on a bolt, each one Tripping edge has. From the tripping edge, the contact surface or the opposing surface is bent so that the pin is pulled out of the receptacle.
    It is advantageous if, when sliding a stop of a jaw on a counter surface of the bolt, the counter surface holds the bolt against displacement in the longitudinal direction of the ski.

    The ski binding 1 shown in Fig. 1 holds a ski boot 2 on a ski (not shown) on which the base plate 3 is screwed. For this purpose, 3 holes 4 to 7 are provided in the base plate. In order to hold the ski boot 2, two jaws 8, 9 are provided which are rotatably mounted around jaw pivot points 10, 11 relative to the base plate 3.
    These pivoting jaws 8, 9 have a holding arm 12, 13 which extends from the jaw pivots 10, 11 to a holding pivot point 14, 15 respectively. At these holding fulcrums 14, 15, a cross member 16 is articulated, via which in the holding fulcrums 14, 15 guided bolts (not shown) are interconnected.
    By the articulated connection of the jaws 8, 9 on the jaw fulcrums 10, 11 with the underlying base plate 3 and the support fulcrums 14,15 with the cross member 16, the cross member on a holding fulcrums 14, 15 connecting line is movable.
    On the holding fulcrums and the traverse opposite side of the jaws 8, 9, a gripper arm 17, 18 at the end of each a gripper pin 19, 20 is provided, which extends approximately parallel to the traverse 16.
    This results in a parallelogram in which the two sides are formed by the jaws 8, 9, the upper line of the traverse and the lower line is formed by the clamped between the Greiferdornen 19, 20 shoe tip 21. The distance between a jaw pivot 10, 11 and a gripper mandrel 19, 20 is about twice as long as the distance between a jaw pivot 10, 11 and a breakpoint 14, 15 of the respective jaw 8, 9. The distance between the two jaw fulcrums 10, 11th is about 1.2 times as long as the distance between the holding fulcrums 14, 15.
    To guide the ski boot 2 with a movement of the jaws 8, 9, the jaws 8, 9 spacers 22, 23, which allow, during the movement of the jaws 8, 9, a pressure from the jaws 8, 9th to exercise the ski boot top 21. These spacers 22, 23 preferably have rolling curves 24, 25 which cooperate with the front abutment surface 26 of the ski boot tip 21.
    The cross member 16 has two transverse arms 27 connected to each other via a cross-arm joint 28. These truss arms 28, 29 are arranged between the holding fulcrums 14, 15 such that they can transmit a thrust force with a component transverse to the line connecting the holding fulcrums 14, 15. Although the cross member 16 consists of two connected to a joint 27 truss arms 28, 29, the cross member 16 thus acts as a one-piece thrust-transmitting rod. This is essentially achieved in that the truss arms 28, 29 have, in addition to the transverse joint 27, a contact surface 30, 31, against which the truss arms 28, 29 rest against one another.
    In Traversengelenk 27, a control cam 32 is provided which cooperates with a control cam 33. This cam 33 has a V-shaped cam surface area 34, in which the cam 32 is in the departure and ascent position.
    The control cam 33 is arranged on a bolt 35 which is displaceable transversely to a line connecting the jaws 10,11 line. A guide (not shown) ensures that the bolt 35 in the downhill and ascent position only exactly perpendicular to the baking fulcrums 10,11 connecting line is displaced.
    The latch 35 is displaceable against the force of a spring 36. This spring 36 rests on the one hand on the bolt 35 and on the other hand on a fixed to the base plate 3 fixed system 37 at. An adjusting screw 38 makes it possible to vary the tension of the spring 36.
    In the basic position shown in FIG. 2, which corresponds to the ascent and descent position, the jaws, 9 are aligned substantially parallel to each other and in the longitudinal direction of the base plate 3 and an underlying ski. The traverse 16 connecting the jaws 8, 9 ensures that in the event of a sideways deflection of a gripper mandrel 18, the opposite gripper mandrel 19 is tracked so that the ski boot 2 remains held by the jaws 8, 9. The spring 36 pulls on the bolt 35 and the cam 33, the cam 32 in the direction of the ski boot 2 away to a ski tip (not shown) and thereby holds the cross arms 28, 29 on a straight, unbent line.
    3 shows that even with a very strong deflection of the ski boot 2, the ski boot is held securely by the gripper thorns 19, 20. In this extreme position, the curved line 24 of the spacer 23 presses against the ski boot tip 21 in order to avoid too much slippage of the ski boot towards the ski boot tip.
    Fig. 4 shows how the cross member 16 can be bent by a displacement of the bolt 35 to the ski boot tip 21. In this case, the truss arms 28, 29 are arranged in a V-shape relative to one another, so that the distance between the holding fulcrums 14, 15 is reduced and the distance between the gripper arbors 19, 20 is increased. As a result, the gripper pins 19, 20 are pulled out of corresponding receptacles 38, 39 in the ski boot 2, whereby the ski boot 2 is released from the binding 1.
    Fig. 5 shows a triggering position, which is achieved when a transverse force of the ski boot 2 relative to the binding 1 and in particular relative to the jaws 8, 9 is too large. In this case, the cam 32 has to move out of the V-shaped cam surface area 34 against the force of the spring 36 in order to allow an extreme displacement of the traverse 16. As a result, the cross member 16 shifts so much that it is arranged in the release position transversely to a line connecting the jaw points 10, 11. In this position too, the spacer 23 presses against the ski boot tip 21 in order to prevent the ski boot tip 21 from slipping forward.

    In particular, Figs. 2 to 5 show that the ski boot 2 is held slightly flexible by the binding 1 and the spring 36 determines the force with which the ski boot 2 is held relative to the base plate 3. By simply moving the bolt 35, the cross member 16 is bent, thereby releasing the ski boot 2. The interaction between the spring force and the shape of the control cam determines the trigger mechanism, which ensures that the ski binding triggers as a safety ski binding at a specific transverse force of the shoe 2 relative to the binding 1. In the embodiment according to FIGS. 6 to 8, the jaws 8, 9 are connected to the traverse 28, 29 as already explained. This allows the jaws 8, 9 are synchronized and spread as shown in Fig. 6 for the entry position. In addition, there are support levers 40, 41, which are loaded by the spring pressure piece 42 and transmit the spring force of the spring 36 on the jaws. For centering of the jaws 8, 9 and transmission of the release spring forces on the jaws 8, 9 is transmitted via the spring pressure piece 42, the spring force to the respective support lever at a release or to both support lever in the rest closed position. Fig. 9 shows a ski binding 50 with a cross member 51, which has two crossbar arms 52 and 53. The truss arm 53 has a slot 54 and the truss arm 52 has a bore 55 into which a retaining cam 56 is pressed, which is guided in the slot 54. As a result, the crossbar arms 52 and 53 are pivotable about the retaining cam 56. The truss arm 53 has a control cam 57 which bears against a cam surface 58 formed at one end of the truss arm 52. As long as the truss arms 52 and 53 are still slightly angled to each other, the spines are 62 and 60 at a distance L1 of 63.5 mm from each other. With a slight movement of the retaining cam 56 towards the ski tip, the control cam 57 travels over the cam surface 58 and pulls the crossbar arms 52, 53 apart so that the spikes 62 and 60 move towards each other at a distance L2 of 62.5 mm. As a result, the ski binding 50 can hold the ski boot (not shown) securely even in the case of a customary play on the spikes 62 and 60 and the receptacles 38 and 39. The movement of the control cam 57 along the cam surface 58 is shown in Figs. 11 to 13. In this case, the pivot point 59 is arranged eccentrically to the arc 61 of the cam surface 58 to pull apart the crossbar arms 52 and 53. FIGS. 14 to 16 show, as in the ski binding according to FIG. 9, abutment surfaces 70, 71, which are arranged on jaws 72, 73, with counter surfaces 74, 75 on a latch 76. The contact surface 71 of the jaw 73 slides on a concave surface designed as a concave surface 75 of the bolt 76. Thus, the jaw 73 blocks the backward movement of the bolt 76. The jaws 72, 73 have contact surfaces 78, 79, which with a mating surface 82, 83rd interact on the latch 76, each having a trigger edge 80, 81. claims
