Definitions
- the invention relates to a release jaw for safety ski bindings according to the preamble of claim 1.
- Such trigger jaws have been known for a long time and are described, for example, in AT-A-294.645.
- the purpose of such jaws is mainly to take into account the allowable load on a skier's leg, i.e. H. to reduce the force that triggers in the horizontal direction than that in the vertical direction in order to keep excessive torsional stress away from the bones.
- H. allowable load on a skier's leg
- the lifting catch device could be released or released without force, and conversely, with a pure stroke release, a force-free release of the transverse catch device was possible. This caused the skier's leg to move first in one direction and then in an oblique direction in the event of a fall.
- FIG. 1 of the cited patent shows a heel holder viewed in section.
- the heel holder has u. a. the following components: a base plate, a pivotable on a bearing block housing with a hold-down and a release spring within the bearing block, which is pivotally arranged in relation to the base plate in a horizontal plane.
- the bearing block carries a lifting rocker arm with a locking surface, which is held pressed in the travel position shown by the force of the release spring against a locking bolt fixed to the housing. Below the locking bolt there is another bolt that is attached vertically to the base plate and interacts with a concave cam on the locking arm. In the illustrated driving position, the pressure of the release spring on the locking rocker causes it to rest evenly on both the locking pin and the vertical pin. If, for example, the sole hold-down device is now subjected to upward stress, it transmits this force via the housing to the latching bolt and, due to the latching surface of the latching rocker, the same is pivoted against the release spring. This pivoting continues until the force acting on the sole hold-down device continues.
- This version is a heel holder with vertical and horizontal release, which mutually influence one another, since the relative position of the control lever and toggle lever changes in both vertical and horizontal pivoting in such a way that they approach each other.
- This heel holder therefore requires a large number of components for the desired release function - such as pairs of link plates and toggle levers, as well as control levers - which results in complex assembly and increased risk of wear.
- Another disadvantage of this heel holder is that the first compression spring relaxes completely when the sole holder is swung up, which leads to a high entry force when the binding is re-entered.
- a layer under the sole, such as B. ice or dirt, causes an early triggering when pivoting the soleplate, which can disadvantageously cause false triggers.
- the invention has set itself the task of creating a trigger jaw that does not have this disadvantage, but rather is suitable to enable diagonal triggering by a load on the jaw housing the force for a vertical release is reduced proportionally, and vice versa, the force for a transverse movement of the baking while simultaneously acting vertical force is to be reduced proportionally without causing false releases in the case of a layer of dirt or ice under the sole:
- the measures according to claim 4 result in a functionally reliable design and a compact design.
- claims 5 and 6 serve to reduce the friction between the pivoting member and the piston as far as possible and thereby prevent triggering delays.
- the features of claim 7 enable the slide to be produced in a known mass production process and an assembly step is carried out during installation path.
- the features of claim 8 simplify the assembly, since the installation of a base plate-fixed control pin is easier to accomplish with conventional means in comparison to the installation of a base plate-fixed control cam in ski binding assembly. Furthermore, the swivel member is more stable in this embodiment than when the control roller is mounted on the swivel member.
- FIG. 1 shows a so-called center-point binding with a release jaw according to the invention in longitudinal section
- FIG. 2 shows details of the control mechanism in a partially sectioned top view of FIG. 1, FIGS. 3 and 4 positions of the locking rocker and the pivoting member in the driving position or in the vertical release position similar to Fig. 1, on an enlarged scale Fig. 5, the position of the pivot member during a transverse pivoting of the binding relative to the base plate in longitudinal section
- Fig. 6 is a plan view of Fig. 5 and Figs. 7 and 8 each a simplified embodiment of Slider with the swivel link in the horizontal release position.
- a base plate 1 which can be fastened on a ski carries a pivot pin 18 about which the entire binding can be pivoted in a horizontal plane by means of a plate 17.
- the individual parts of the binding are essentially integrated in the plate 17.
- a dash-dotted shoe 5 can be fixed by means of sole hold-down 4.
- the sole hold-down devices 4 are intended to release the shoe 5 when the skier's leg is overloaded in the horizontal, vertical or diagonal direction.
- This release is caused in the vertical direction by swiveling up the housing 3, which is designed as a tread plate on its upper side, this swiveling up being initiated by the transmission of the force F 1 from the shoe to the sole hold-down device 4 and by this via a linkage device to the housing 3.
- the horizontal release takes place by pivoting the plate 17 relative to the base plate 1, whereby a locking device 31 opens and the sole hold-down devices 4 fold away to the side. All of the operations described above act against the force of springs, not shown.
- the housing 3 which is designed as a tread plate on its upper side, is a robust component which is essentially made of one piece and which is mounted, for example, by means of a transverse axis on a bearing block 2, which bearing block 2 is one Forms part of the plate 17.
- the housing 3 has lateral tabs 33 (cf. FIG. 2) which carry the two clamp-like sole hold-down devices 4 via bearing pins 34 which are only indicated.
- the housing 3 is constructed symmetrically over the vertical center plane on the top of the base plate 1.
- the sole hold-down devices 4 are shown in FIG. 1 approximately perpendicular to the top of the housing 3 in the driving position.
- the sole hold-down devices 4 grip opposing points of attack 35 on the dash-dotted shoe 5 by means of lateral surfaces 36, transverse surfaces 37 to the longitudinal direction of the ski, and hold-down surfaces 38, which extend approximately parallel to the upper side of the housing 3.
- the dash-dotted shoe 5 is thus held pressed sideways in the ski position, in the longitudinal direction of the ski and to the top of the housing.
- the individual sole hold-down devices 4 are each by means of a control rod 39, which are articulated on the sole hold-down device 4 at one end in a manner not shown and on their side facing away from the sole hold-down device 4 End region carry a profile bolt 40 with a parallelogram-like outline, locked in that the profile bolt 40 is held in a cranked control slot 41 (not shown in more detail) on the crank (not shown) by a locking member 42.
- the offset of the control slot 41 forms a bulge to overcome which the profile bolt 40 should slide upward in the control slot 41. However, this sliding afterward is prevented by the locking member 42 in that the locking member 42 engages in the travel position between the top of the profile bolt 40 and a guide surface of the control slot 41.
- the recessed recess of the other guide surface which is the same as the bulge of the one guide surface, which is not shown, thus provides a recess for the profiled bolt 40, provided that the locking member 42 is not in engagement. If the blocking member 42 is removed, in the event of a lateral load on one or both of the sole hold-down devices 4, the profiled bolt 40 can be guided through the control rod 39, along one guide surface of the control slot 41, overcoming the bulge, as a result of which the shoe 5, shown in broken lines, disengages from the sole hold-down device 4 is released. When the sole holding-down device (s) 4 comes back into driving position, the profiled bolt 40 also briefly slides on the other guide surface. Instead of the profile bolt 40, a roller could also be provided.
- the sole retainer 4 is pivoted back by a spring, not shown.
- the locking member 42 is designed pawl-shaped and pivotally mounted on a transverse axis, not shown. In the travel position, the locking member 42 (as shown) engages between the profile bolt 40 and the guide surface of the control slot 41.
- the profile bolt 40 is rigidly connected to the control rod 39, for example by a press fit in a bore in the end region thereof.
- the pivoting movement of the locking member 42 is brought about by an engagement part 43 which engages around the locking member 42 and pulls forward in the longitudinal direction of the ski when the plate 17 is twisted.
- the attack part 43 is mounted in the plate 17 and held in its basic position by a spring, not shown. At its end facing away from the locking member 42, the engagement part 43 engages on a part 44 which is fixedly connected to the pivot pin 18. As can be seen in FIG. 1, the part 44 can be divided in two in the axial direction for reasons of assembly simplification.
- the locking member 42 In order to cause the force responsible for horizontal rotation of the plate 17 to be transmitted when the housing 3 is not pivoted vertically, the locking member 42 has a tine which is elongated downwards. which also swings up successively with respect to an engagement part 43 by pivoting up the housing, but always remains in engagement with the latter.
- the backward curvature of this tine corresponds to a radius to the transverse axis 32.
- a control cam 19 is also provided on the base plate 1 and, as shown in FIG. 1, is connected to the base plate 1 by means of rivets or else in one piece.
- a control roller 16 is supported on the cam 19.
- the control roller 16 is mounted in a slide 12, which has a longitudinal slot 23 against lateral pivoting, in which longitudinal slot 23 a bearing block 24 engages.
- the end of the slide 12 facing away from the control roller 16 presses against the lower region of a swivel member 11 which is mounted in its upper region on a latching rocker 8 which is mounted in a fixed manner in its lower region.
- the pivot member 11 is supported with its side facing away from the slide 12 against a slide plate 20 which is fastened to a spring piston 14.
- the spring piston 14 presses against a release spring 6, which is arranged in a recess in the bearing block 2.
- the swivel member 11 is approximately U-shaped, the side resting against the sliding plate 20 being the transverse web 22 of the Us, while the two legs 21 each have a bore for receiving a bolt 13 which, as already mentioned , is mounted in the locking rocker 8.
- the release lever 7 also engages the bolt 13.
- the locking rocker 8 is divided into two, only one half 81 being visible in FIG.
- FIG. 3 shows the driving position
- FIG. 4 shows the triggering time.
- the trigger point 45 is defined by a locking lug of the locking surface 8a of the locking rocker 8. If the locking bolt 10, driven by the force F, moves upward on the sole hold-down device 4, the locking rocker 8 is counter-rotated about its pivot axis 46, which is mounted in the bearing block 2 the spring piston 14 or the sliding plate 20 is pivoted, whereby the trigger spring is compressed. From this trigger point shown in FIG.
- the housing can be pivoted upward with F, with considerably less effort being exerted, as a result of which the opposing attack points 35 are released from the sole hold-down devices 4.
- the transverse axis 32 serves as a pivot axis for the housing 3.
- the pivot member 11 is pivoted less about the pivot axis 46, ie the trigger spring 6 is less compressed.
- the diagonal effect during the triggering or a diagonal triggering is now brought about by the fact that the horizontal rotation is also transmitted to the pivot member 11 via the slide 12.
- a simpler embodiment of the device for reducing the triggering force in the vertical direction while simultaneously acting a horizontal force on the housing, as can be seen from FIG. 7, is given when the slide 112 is connected directly (preferably in one piece) to the pivoting member 111, the pivoting member 111 is approximately L-shaped with the slider 112 and the slider 112 carries the control roller 116.
- the control curve 119 is arranged further on the extended base plate 101.
- the control curve 119 is concavely curved in the horizontal direction in accordance with the desired force profile and curved in the vertical direction in such a way that when the pivoting member 111 is pivoted about the bolt 13, the control roller 116 slides vertically thereon, without thereby changing the compression of the release spring 6.
- a similar principle is shown in FIG.
- control cam 219 is arranged directly on the lower end region of the pivot member 211 which is formed in one piece with the slide 212 and interacts with a control roller 216 which is arranged on a control pin 28, the control pin 28 is fixed on the base plate 201.
- the control curve 219 is concave in the horizontal direction, but is convex over the cross-sectional height.
- the arbitrary disengagement from the binding is carried out by depressing the release lever 7, which, by means of the bolt 13, pivots the locking rocker 8 back against the release spring 6.
- the tripping lever 7, like the locking rocker 8, is mounted on the bearing half-pin 46 in a bearing block-fixed manner.
