Definitions

  • the invention relates to a ski binding part, in particular a front jaw, with a guide rail which can be fastened on the top of a ski and on which a jaw unit which is displaceable in the longitudinal direction of the ski and which is fastened to a base plate and has a housing and a locking device which locks the jaw unit in predeterminable sliding positions with the guide rail has on the jaw unit movably held latching part, which can be brought by a spring in positive engagement either with one of complementary latching recesses of the guide rail, on the latching part a pivotable actuating member for disengaging the latching part engages from the complementary latching recess.
  • the adjustable ski binding part has an adjustment device with a latching device.
  • the heel holder In the conventional ski bindings, the heel holder is generally guided displaceably by means of a base plate on a guide rail which can be fastened on the top of the ski.
  • the heel holder or its base plate has a detachable catch
  • the guide rail has a counter catch.
  • Such a locking device is described for example in CH-PS 469.492. With this construction, locking is disadvantageously only possible if the latch and housing are exactly opposite one another, which means that two hands are absolutely necessary for locking: one which guides the jaw body and a second which actuates the lever.
  • Flaps have therefore been developed which enable a locking part to be disengaged from an opposing locking recess.
  • Such adjustment devices have already become known in various embodiments.
  • the AT-PS 368.394 relates to a device for ski bindings, which comprises a carriage carrying the binding part and a ski attached to the ski, forming a guide for the slidable in the longitudinal direction of the base plate, wherein an arbitrarily releasable locking is arranged in the area between the slide and the base plate and the Binding part bears under the action of one or more shear springs in the state of use on the ski boot, a further plate extending parallel to the base plate and also being displaceable in the longitudinal direction of the ski being arranged between the slide and the base plate, and with one end on the plate and the other End on the slide supporting thrust spring bxw, supporting pushing springs pushes or pushes the slide with a stop against a stop or a support device of the plate adjustable in the longitudinal direction of the plate, and the locking device is provided between the plate and base plate and the v
  • the support device that can be created has an eccentric that is rotatably mounted
  • the invention has now set itself the goal of creating a displaceable or adjustable front jaw with a latching device, which enables secure latching and unlatching by means of one-hand operation even on the slopes in a comfortable manner and thus also a shift in the center of gravity is possible.
  • the actuator as known per se, is mounted on the locking part and is provided with at least two surfaces or surface sections which form an angle with one another and each of which lies at a different distance from the bearing point and thus determines the latched or unlatched position of the latching part, and that the two surfaces or surface sections in these layers are optionally held pressed against the housing by the spring.
  • the actuator has a support point at which the actuator is supported during its pivoting on the housing, the support point in the closed or open position of the actuating lever on one or the other side of a plane located which passes through the center line of the bearing; or that the actuating member has a support point rotatably mounted in the housing, at which the actuating member is supported on the housing during its pivoting, the bearing point being displaceably arranged in the latching part or in the actuating member by means of a clearance slot and in the closed or open position of the actuating member one or the other side of a plane that passes through the support point and with the top of the housing a preferably right angle e. closes.
  • the first embodiment is formed at its support point by the convergence of the two surfaces, the support point preferably being formed by a rounding.
  • the further embodiment according to which the support point is arranged on the steep curve of an eccentric, brings about a very simple adjustment of the latching part from the latched position into the unlatched position, the top side of the housing being largely protected by the rounding.
  • the actuator can, as is known per se, be designed as an eccentric cam, the latching effect then in particular occurs with certainty when, in the locked position, one surface of the actuating member lies in a parallel plane and the other surface lies in a normal plane to the longitudinal central axis of the locking part.
  • the actuating element is a handle which is connected in one piece to the surfaces and the steep curve.
  • This handle can have any shape and can therefore be optimally adapted to the styling of the cheek body.
  • the handle can be a one-armed lever, one end of which carries a grip part and the other end of which carries the surfaces and the steep curve.
  • the handle can be designed as a rotary knob or as a rotating roller.
  • the handle can be arranged on a shaft which shaft carries the eccentric.
  • a very reliable and easy to manufacture design of the locking ter is according to a further embodiment of the invention characterized in that it has at its end facing the guide rail a piston carrying the locking pin with an abutment for the spring, which piston in a, preferably cylindrical recess in the housing is guided, the housing forming a counter bearing for the spring on its area facing away from the guide rail.
  • This design also enables particularly good power transmission between the locking pin and the locking recess, the shear forces being effectively absorbed by the recess in the housing.
  • the actuating member is at least partially recessed in the locked position in the housing. The security will thereby increased when the handle part, viewed in the direction of travel, is arranged in front of the bearing point and extends against the direction of travel.
  • Another particularly advantageous form of the invention is characterized in that the bearing point slidably engages in a substantially horizontal release slot of the latching part, at least one end of the release slot being further away from an imaginary vertical center line of the latching part than the support point.
  • the locking part is made twice and is arranged on both sides of the skin center line.
  • actuating member can only be actuated by a tool, which at least makes unauthorized manipulation by unqualified persons more difficult.
  • Fig.l a locking device according to the invention in section with a lever-like handle part
  • Fig.2 a locking device with a knob-like handle part
  • Fig.3 a locking device with two locking parts
  • Fig.4 a locking device with a release slot for the bearing point in the engaged and disengaged state.
  • the exemplary embodiment according to FIG. 1 is constructed as follows:
  • the top of a ski 1, a guide rail 2 is attached in a manner not shown.
  • the guide rail 2 has locking recesses 2a which can be brought into engagement with a locking bolt 4.
  • the locking pin 4 is integrally connected to a piston 5, which in turn is provided with a guide rod 3 pointing in the opposite direction of the locking pin 4, wherein locking pin 4, piston 5 is connected, which in turn is connected to one in the opposite direction of the Locking pin 4 facing guide rod 3 is provided, locking pin 4, piston 5 and guide rod 3 together form the locking part 6.
  • the piston 5 is guided axially in a recess 7 of a housing 10. In a hole or recess with a smaller diameter, the guide rod 3 is guided through the housing 10 to the outside.
  • a cavity is thus created between that boundary of the recess 7 that faces away from the guide rail 2 and the upper side of the piston 5, which also faces away from the guide rail 2.
  • a spiral spring 8 is arranged in this cavity, which is thus supported on the one hand on an abutment 5a formed by the upper side of the piston 5 and on the other hand on a counter bearing 9 formed by the housing and acts on the piston 5 in the axial direction. By this spring 8, the locking part 6 and thus the locking pin 4 is always pressed against the guide rail 2.
  • the guide rod 3 protruding from the housing 10 has an engagement point 12 which is mounted in an actuating member 27.
  • the actuating member 27 is designed as a handle with a handle part 14, the bearing point 12 for the latching part 6 being provided at the end opposite the handle part 14.
  • This end of the actuator 27 also has a surface 17 which lies flat on the upper side 16 of the housing 10 in the latched position shown.
  • a further surface 18 extends at right angles to this surface 17 and converges with surface 17 on a steep curve 15 of an eccentric.
  • the support point 29, via which the actuating part 27 can be pivoted, lies on this steep curve 15.
  • the housing 10 is designed so that the handle is practically integrated into the silhouette 19 of the housing 10 and does not protrude beyond it in the locked position.
  • the latching part 6 the bearing point 12, the surfaces 17, 18 including the eccentric part curve 15 and the handle part 14.
  • the configuration the housing 10, the locking part 6 and the guide rail 2 is identical to the embodiment of Fig.l.
  • the shape of the handle part 14, which is designed as a rotary knob or roller, differs, the unlocked position being shown in FIG. 2 with full lines.
  • the surfaces 1 8 also include the eccentric subcurve 15 in this case, but the eccentric 25 as a separate component is integrally connected to the handle part 414.
  • the lifting height 20, which defines the difference between the locked and unlocked position, is here also effected by the different distance of the surfaces 17, 18 from the bearing point 12.
  • the rotary knob or the roller In order to get from the unlocked position shown in FIG. 2 to the locked position, which is shown in dashed lines, the rotary knob or the roller must be turned, whereby the eccentric 25 slides along its eccentric cam 15 with the support point 29 along the housing until the surface 17 comes into contact with the top of the housing 10. During this process, the locking part 6 is displaced by the spring 8 in the direction of the guide rail 2 when the locking pin 4 finds a locking recess 2a.
  • FIG. 3 shows in a somewhat more detailed form a possible embodiment of the guide rail 52, which is formed from a profile material which has a base part 52g, which is fastened to the ski, and is bent vertically upwards at its edges, as a result of which arms 52c, 52d are formed.
  • the housing 510 has feet 23 which are received by the groove formed between the parts 52e and 52f and the base part 52g. To improve the sliding properties, a sliding insert 24 is provided between the feet 23 and the guide rail 52.
  • the latching part 66 has a slot 36 in which the bearing point 612 is slidably arranged and is formed by a bolt which is fastened to the lever-shaped handle part 33.
  • the grip part 33 has a support point which is supported as a spherical section 34 in a pan 32 on the upper side 37 of the housing.
  • the surface 17 is formed by the body of the handle rope 33, while the surface sections which can be brought into engagement with the upper side 37 of the housing in the course of unlocking are on the ball section 34.
  • the effect of the unlatching or locking is also determined here by the different distance of the bearing point 612 from the surface 17 or from the surface sections on the ball section 34, which are not designated.
  • the grip part 33 stops in the unlocked position when the bearing point 612 passes at least with an amount U over a vertical plane through the center line 41 of the support point 34.
  • the amount 0 is determined because the slot 36 allows the bearing point 612 to be exempted by its end 35, which extends beyond said plane.
  • the slot 36 could also be designed in a handle, in which case the bearing point 612 would be formed by a bolt which is fixedly connected to the latching part 66.
