Definitions

  • the present invention relates to a toe of a safety ski binding according to the preamble of claim 1.
  • a generic toe piece is known from EP-A-0 271 693.
  • This known construction has a two-armed lever mounted on a driver. This two-armed lever causes friction when pivoting between it and the arms of the two side jaws. Such friction is undesirable in the function of a triggering ski binding, since it negatively influences the triggering function of the respective side cheek in a way that cannot be clearly predetermined.
  • the object of the present invention is therefore to develop a generic toe piece in such a way that such frictional influences which impair the functioning of the toe piece are avoided.
  • the two support lever arms can be pivoted independently of one another and are spring-loaded in the support direction.
  • the support lever arms are therefore identical and easier to carry out than before. Due to the independence of the support lever arms from one another, the second arm does not necessarily pivot when the first arm is influenced. This avoids the friction between the second arm and the side jaw supported on it.
  • control part can expediently be a control lever mounted coaxially to the support lever arms on the coupling. It has proven to be useful that the control lever is single-armed and forked, that a stop extends between the prongs of the fork, which lies in the plane of symmetry of the toe piece, and that each fork prong has a driver only in the release direction for the support lever arm assigned to it .
  • the control lever can also be designed with three arms.
  • an arm extends between two stops in such a way that in its normal position it lies in the plane of symmetry of the toe piece.
  • the two other arms are at least approximately at right angles to the first arm and stretched relative to one another.
  • the arms lying stretched relative to one another can each serve to interact with a support lever arm.
  • the support lever arm has an actuating pin in this case.
  • both arms of the control lever are spaced apart from the associated actuating pins. This allows a compact construction with an optimal swivel range of the four-bar linkage.
  • a particularly simple construction is achieved in that a pin provided on the support lever arm serves as the control part. In this case, there is no special control lever.
  • the stop cooperating with the control part can be connected indirectly to the base plate via a housing part, for example a cover.
  • the side jaws are expediently influenced by a return spring.
  • a return spring it has proven to be advantageous that a helical spiral spring is provided as the return spring and that one leg of the spiral spring acts on the side jaw and the other on the support lever arm assigned to this side jaw.
  • a part arranged on the coupling and overlapping the sole can be provided, which forms or influences the part of a wedge thrust transmission, via which the support lever arms can be brought into their release position.
  • the above-described front jaw is thus further developed so that it offers the possibility of releasing the locking of the side jaws in relation to the coupling when the side jaws are overloaded, so that in this case they can swivel out only by overcoming the force of the return springs.
  • the support surfaces in the side jaws are known to be upwards Shoe formed obliquely. After a certain constructively predetermined lifting of the front end of the sole, both support lever arms are actuated and brought into their position in which they release the side jaws so that they can swing out about their articulation axes.
  • the drive member of the wedge thrust mechanism can be a lever arm of a two-armed lever mounted on a horizontal transverse axis in the coupling, the second arm of which forms a central part overlapping the sole and which can be pivoted to a limited extent against the force of at least one retaining spring, in which case each Support lever arm has an upwardly extending shoulder which is chamfered in a wedge shape and overlapped by a wedge surface of the first lever arm.
  • the spring loading a support lever arm expediently serves as a holding spring of the two-armed lever.
  • a design variant is characterized in that the side jaws serve as parts overlapping the soleplate, that the drive member is a lever mounted on a horizontal transverse axis in the coupling which can be pivoted to a limited extent against the force of a retaining spring, such that each support lever arm extends upwards Approach, which is chamfered in a wedge shape and overlapped by a wedge surface of the lever, and that at least the coupling is vertically elastically movable to a limited extent.
  • the pin provided as the control part preferably forms with its free end the projection overlapped by the wedge surface of the corresponding lever arm.
  • a still further simplified construction provides that the side jaws serve as the parts overlapping the sole, that the drive member of the transmission is a surface of a housing part that is immovable relative to the base plate to the vertical transverse plane on the shoe side, that each support lever arm carries an upwardly extending nose, the free end of which is chamfered in a wedge shape and is intended to cooperate with the inclined surface of the housing part and that at least the coupling can be moved vertically elastically to a limited extent.
  • the pin provided as the control part advantageously forms the beveled nose with its free end.
  • a housing which has a base part 1 which can be fastened on a ski in the customary manner.
  • a cover part 2 or 3 is connected to the base part.
  • the coupling of which consists of two parts 8, 9 lying parallel to one another.
  • the coupling serves as a support member for two side jaws 10, 11 and 12, 13, which each have a pivot pin 14 or 15 of the coupling on the levers are stored.
  • the quadrilateral joint is under the influence of a locking device, not shown, which is not essential to the invention and is therefore not shown in order to complicate the figures.
  • a locking device not shown, which is not essential to the invention and is therefore not shown in order to complicate the figures.
  • the four-bar linkage is held in its normal position of use under the spring force of the latching device. If a force is transmitted from one of the side jaws, which is also not shown, which exceeds the pretension of the spring, the four-bar linkage swivels about the axes 4, 5, but the side jaws do not change their position relative to the coupling. When the force decreases, the four-bar linkage returns to its normal position under the influence of the spring.
  • the triggering of the side jaws is described below with reference to the individual embodiments.
  • the side jaws 10, 11 are extended beyond the pivot pins 14, 15.
  • the free ends of the arms 16, 17 formed in this way each rest on a support lever arm 18, 19, both of which are mounted on an axis 20 which is held on the coupling parallel to the pivot pins 14, 15.
  • the side jaws are normally held immovably in relation to the belt.
  • the individual parts of the toe piece normally assume their position shown in Fig. 2.
  • a force is exerted on the side jaw 10 transferred, which exceeds the bias of the spring of the locking device, there is a pivoting of the four-bar link with respect to the running direction to the right (see Fig. 3).
  • the four-bar linkage returns to the starting position according to FIG. 2 under the influence of the force of the spring of the latching device.
  • the control lever 21 mounted on the axis 20 strikes with its arm 22 on one of the stops 23 or 24 in the housing
  • the control lever causes a release movement when the four-bar linkage is pivoted slightly of the corresponding support lever arm 18, whereby the arm 16 of the side jaw 10 is unlocked so that the side jaw can assume its release position shown in FIG. 4 under the influence of a shoe.
  • the control lever 21 is T-shaped. Its arms 25, 26 are used to actuate a support lever arm 18, 19, for which purpose they each have an actuating pin 27 and 28, respectively. As can be seen from FIG. 2, in the normal position of the four-bar linkage, the arms 25, 26 of the control lever 21 are spaced apart from the actuating pins 27, 28 of the support lever arms. As a result, a large swivel range of the four-bar linkage is achieved with a compact construction.
  • Each support lever arm 18, 19 is under the influence of a retaining spring which is indicated by an arrow A or B and which tries to hold or reset the support lever arm in its position shown in FIG. 2.
  • the side jaws 10, 11 are also influenced by a return spring, which is indicated by the arrows C and D, respectively.
  • helical spiral springs are used as return springs, which are supported on the pivot pins 14, 15 of the side jaws 10, 11 and which act with one leg on the side jaw and with their other leg on the support lever arm assigned to them.
  • Such a spiral spiral spring thus takes on a double function (spring A, C or B, D).
  • the housing comprises the base part 1 and the cover part 2 and carries the axes 4, 5.
  • the four-bar linkage includes the lever 6, 7 and the coupling made of parts 8 and 9.
  • the side jaws mounted on the pivot pins 14 and 15 are designated by 12 and 13, since they each have an inclined support surface 30 for the front end of the shoe sole, so that at a movement of the sole end upwards onto the sole exerts a certain wedge thrust effect against the pressure applied by the heel part, not shown.
  • the control lever 21 is present for triggering the side jaws with a correspondingly large lateral load (FIG. 5), which in turn interacts with stops in the housing, but which in this case is designed as stud bolts 31, 32 are. Because of the cut made for the sake of better illustration, the control lever is no longer present in FIG. 6. With regard to its function, reference is made to FIGS. 2 to 4.
  • part 8 of the coupling is provided with a part that overlaps the front sole end of a shoe and is designed as a two-armed lever 33. It is mounted on an axis 34 in part 8 of the coupling. His arm 35 serves to overlap the sole, while his arm 36 forms the drive member of a wedge-type transmission.
  • both the support lever arms 41, 42 and the side jaws 12, 13 are again under the influence of retaining or return springs.
  • the return springs of the support lever arms 41, 42 also act on the lever 33 in the sense of a reset via the shoulders 39, 40.
  • FIGS. 9 and 10 represents a simplification of the embodiment according to FIGS. 5 to 8.
  • a one-armed lever 43 is used here, which is mounted on the axis 34 in part 8 of the coupling. It takes over the function of the lever arm 36 in the above-described embodiment. Accordingly, the support lever arms and their approaches are the same and therefore designated 41.42 and 39.40.
  • the two side jaws 12, 13 with their oblique support surface 30 take over the function of the part 35 that grips over the sole , 7 of the quadrilateral created for the vertical axes 4.5.
  • This pivoting movement of the lever 6, 7 takes place against the resistance of the locking device mentioned and not shown, which holds or tries to keep the four-bar linkage in its normal position of use.
  • FIGS. 9 and 10 finally show another embodiment which is based on that of FIGS. 9 and 10.
  • the lever arm 43 is also omitted.
  • the cover part of the housing designated here 3 there is a surface 45 inclined towards the shoe created by an approximately transversely extending keyway 46.
  • the inclined surfaces of the lugs 39, 40 of the support lever arms 41, 42 come into direct contact with the surface 45, whereby the pivoting of the support lever arms into their release position is achieved, so that the side jaws 12, 13 as in FIG Fig. 12 shown spread apart and can release the sole upwards.
  • the keyway 46 in the cover part 3 is dimensioned in its length so that the ends finally hold back the support lever arms during a lateral movement of the four-bar linkage, so that these then release the side jaws.
