Definitions

  • the invention relates to a ski binding which has a sole holder which is movably arranged in a vertical plane on a base body and has a first latching element, which is in engagement with a latching member which is designed as a pivotable cam on the base body, the base body being in an approximately right-hand position relative to the plane of movement of the sole holder Angled plane is movably arranged on a base plate and is also latched, and wherein the sole holder has a second latching element which engages in an approximately cam-shaped locking element arranged on the ski, the cam-shaped locking element having in its center a recess with vertical surfaces, the distance between them to each other corresponds approximately to the diameter of the latching element, the depth of engagement of the latching element in the recess being equal to or greater than the radius of the latching element.
  • Ski bindings of the type mentioned at the outset which were produced and sold in accordance with AT-A-305 843, are extremely popular. They also serve well the purpose of this binding, namely a controlled release of the ski boot with forces acting simultaneously in the horizontal and vertical plane, with a lock preventing the heel holder from being actuated when the forces acting only in the horizontal plane.
  • a horizontal release with conventional heel holders of safety ski bindings only takes place in the cheek area.
  • the aim of the invention is to improve the known solution by increasing the effective height of the blocking zone without changing the dimensions of the latching element and / or of the vertical surfaces delimiting the recess.
  • the set goal is achieved according to the invention in that the second latching element provided on the sole holder and the latching element arranged on the ski are supported in a spring-loaded manner relative to one another.
  • This measure according to the invention increases the effective height of the blocking zone, because during a predetermined, mostly slight lifting of the sole holder from the top of the ski, either the locking element provided on the sole holder is acted upon by the force of a spring or is still immersed in the recess limited by vertical surfaces, or the locking element arranged on the ski, loaded by a spring, follows the height movement of the sole holder.
  • an increased blocking zone is thus achieved without a change in the dimensions of the latching element and / or the vertical surfaces delimiting the recess being necessary.
  • the effective enlargement of the restricted zone thus increased can be determined by the designer in a wide range by appropriate selection of the spring.
  • a ski binding which is designed with two latches, the second latching element provided for triggering in the horizontal direction and the latching member arranged on the ski also being resilient relative to one another are supported, but in this known solution the second locking element is not arranged on the sole holder.
  • This known ski binding can therefore not contribute to solving the object on which the object of the application is based, which is aimed at increasing the effective height of the restricted zone, i.e. Enlargement of the area in which triggering in the horizontal plane is excluded.
  • Such a blocking zone is however not provided at all in the ski binding known from DE-A-2 340 420, but this binding is also triggered by forces acting only in the lateral direction.
  • a roller forming the latching element is mounted on an axis, which axis in turn is mounted in the sole holder in two elongated holes running in the vertical direction and relative to the sole holder by means of a spring fastened in the sole holder, e.g. is preloaded by means of a pair of spiral springs.
  • the resilient support of the roller on / in its bearing points provides a particularly simple construction.
  • An advantageous embodiment of this inventive concept is characterized in that the axis of the roller lies in the open position of the ski binding on the lower region of the two elongated holes and, in the closed state of the ski binding, lies against the force of the two spiral springs on the upper region of these elongated holes .
  • the spiral spring is only preloaded to the extent that when the heel holder is open, the axis of the roller assumes the lower position just described.
  • the latching element is formed by at least one support, possibly by two support parts, which is height-adjustable relative to the base plate and is elastically supported on the latter with the interposition of at least one spring, preferably by a pair of springs, or are.
  • two leaf springs are provided as springs, which are arranged between the top of the base plate and the underside of two support regions of the latching element, with retaining pins being fastened in both side regions of the base plate which are angled downwards and which have elongated holes in the support extending in the vertical direction correspond.
  • the locking member is designed as an approximately U-shaped body in plan view, the web of which is formed by the support and the two legs of which are each pivotably mounted on a pivot pin attached laterally to the base plate. In this way, the locking member can be made particularly stable.
  • the two support regions of the latching member have blind holes which are open at the bottom and in which one end of each coil spring is supported, the other ends of each of these springs being supported on the upper side of the base plate, and the base plate being supported two bolts arranged symmetrically relative to the longitudinal axis of the ski and extending in the longitudinal direction of the ski are fitted, each of which is fastened in a sheet metal wall bent from the material of the base plate, on each of which bolts one of the two supporting parts having the individual control surface regions is pivotably mounted.
  • FIG. 1 and 2 show details of the second locking element in connection with the locking element arranged on the ski, corresponding to FIGS. 1 and 2 of AT-A-305 843, the locking element resting on the locking element; 3 shows a representation similar to FIG. 2, the sole holder being closed and the latching element engaging in the latching member, in all cases with spring-loaded support of the latching element; 4 and 5 a first spring-loaded embodiment of the locking element arranged on the ski, similar to FIGS. 1 and 2 and FIG. 6 a modification of the spring-loaded support of the locking element arranged on the ski, similar to the embodiment according to FIG. 5.
  • FIGS. 1 and 2 the portion of a heel holder 1 which relates to the actual subject matter of the invention is shown.
  • the type of adjustment is known per se, it does not form an object of the invention.
  • a base body, not shown here, is mounted on the base plate 4 in a known manner and can be pivoted in the horizontal plane about a holding bolt which is perpendicular to the base plate 4.
  • a pivot axis running transversely to the longitudinal axis of the ski 2 is mounted, about which a housing 5 can be pivoted up.
  • the sole holder 8 is equipped in a known manner with a hold-down 8a for a ski shoe, not shown here, and with a spur 8b, on which the ski shoe can engage to close the heel holder 1.
  • the area of the sole holder 8 which carries the spur 8b is offset relative to the housing 5, so that an inner wall 8c is formed on the sole holder 8, which wall runs essentially parallel to the front side of the housing 5 and delimits a free space 11 with this side.
  • the second latching element is designed as a roller 9, which by means of an axis 10 in a guide 8d of the sole holder 8 designed as an elongated hole and a further guide 5a of the housing 5 also designed as an elongated hole is stored.
  • the two guides 8d, 5a run vertically, the axis 10 of the roller 9 being pushed into a downward position by means of two springs 13, 14, which in the present case are designed as spiral springs.
  • the axis 10 is seated on the lower areas of the two guides 8d, 5a.
  • the roller 9 with its axis 10 remains under the action of the two spiral springs 13, 14 in the position described until an upward force on the roller 9 exceeds the force of the two spiral springs 13, 14.
  • the position of the roller 9 and axis 10 described is maintained in the open state of the heel holder 1 and also in its swung-down position. Only when the ski boot, acting on the spur 8b of the sole holder 8, pivots the heel holder 1 into the closed position, is there an upward force acting on the roller 9, as will be described below.
  • the base plate 4 carries a locking element 6 in that area which corresponds approximately to the width of the roller 9.
  • This locking element is e.g. attached as a support 12 on the base plate 4, therefore forms a unit with this. It can also be designed from the material of the base plate itself.
  • the locking member 6 or the support 12 has, as can be better seen in FIG. 2, a control surface 7 on which the roller 9 rests or slides along in a manner to be described.
  • the control surface 7, viewed in the pivoted-down position of the sole holder 8 has two essentially vertical surfaces 7a, 7b in the region adjacent to the roller 9 and, in each case, a curved section 7c, 7d following them. In the position shown in FIGS. 1 and 2 there is a distance a between the underside of the spur 8b of the sole holder 8 and the top of the guide rail 3 (or the ski 2) which is greater than a height distance h to be described.
  • the two springs 13, 14 are preloaded even more than their original preload, so that they always endeavor to urge the axis 10 of the roller 9 in the direction towards the top of the ski 2a. This striving of the two springs 13, 14 is thus constantly present in the closed position of the heel holder 1. If, for example, forces act on the ski boot during the downhill run, whereby it tries to lift the hold-down 8a of the sole holder 8 from the upper side 2a of the ski, the axis 10 and thus also the roller 9 become already when the sole holder 8 is slightly lifted off the upper side 2a pressed down by the two springs 13, 14.
  • a relative movement takes place between the axis 10 and the roller 9 and the two guides 8d, 5a of the sole holder 8 or the housing 5, the axis 10 maintaining its position and the sole holder 8 moving upwards away from the top of the ski. Such a relative movement continues until the two lower regions of the guides 8d, 5a come into contact with the axis 10.
  • the roller 9 remains in the recess of the control surface 7 formed by the two vertical surfaces 7a, 7b until the end of this relative movement.
  • the exemption h thus extends that area of the control surface 7 which is formed by the two approximately vertical surfaces 7a, 7b and which represents a blocking zone for the heel holder 1 acting against purely lateral forces.
  • the measure of locking the heel holder 1 against purely lateral forces and allowing the triggering process to act exclusively through the front jaw in such cases is known from the parent patent.
  • the heel holder 1 should be released after the so-called diagonal forces acting simultaneously in the horizontal and in the vertical plane. Since the height of the restricted zone is inevitably determined by the dimensions of the roller and such rollers can only be used for construction reasons with limited dimensions, it has long been a problem to increase the effective height of the restricted zone without increasing the dimensions of the roller.
  • the elastic support just described solves this problem without having to enlarge any dimensions.
  • the stability of the entire system is also maintained because, without the creation of forces acting in the vertical direction, the blocking force curve between the locking element 6 arranged on the ski, the roller 9, the axis 10 and the sole holder 8 is continuous.
  • FIGS. 4, 5 and 6 show three further possibilities of the elastic support according to the invention.
  • the roller 9 ' is mounted on the sole holder 8' in a stationary manner by means of its axis 10 'and rotatably on the axis 10'.
  • the elastic support takes place in the area of the respective latching element 6 ', 6 ", 6'". The following description is limited in all cases to the design and function of the elastic support according to the invention.
  • the locking member 6 ' is formed by a support 12' which is supported on the base plate 4 'of the heel holder 1' with the interposition of two springs 13 ', 14'.
  • the two springs 13 ', 14' are provided as leaf springs designed with free ends pointing upwards; these springs could of course also be arranged in a position with free ends pointing downward on the base plate 4 '.
  • the leaf springs 13 ', 14' are already preloaded in the position shown, which illustrates the assembled state of the locking member 6 '.
  • the support 12 ' has guides 12'a, 12'b on both sides, which are designed as elongated holes lying in the vertical plane.
  • Pins 15, 16 engage on both sides in the individual guides 12'a, 12'b of the support 12 'and are attached to / in the two side surfaces of the base plate 4'.
  • similar guides and pins viewed in the longitudinal direction of the ski, can be provided at a distance from the guide described, this region of the support 12 'correspondingly only having a height which is one Operation of the heel holder 1 'in no way hindered.
  • the support 12 ' is thus designed as a type of spring-loaded slide relative to the base plate 4'.
  • the latching member 6 is designed as a body which is approximately U-shaped in plan view, the web of which is formed by the support 12" and the two legs 6 "a, 6" b of each in the base plate 4 "attached pivot pins 17, 18 are pivotally mounted. Only the leg 6" a with the pivot pin 17 is visible in FIG. 5.
  • the support 12 "in the present case moves as a pivoting member, the greater the difference between a movement in the vertical plane according to the exemplary embodiment according to FIG. 4 and the pivoting movement according to the exemplary embodiment according to FIG. 5 the distance between the support 12 "and the two pivot pins 17, 18 is.
  • the inclination is determined by the aforementioned distance between the support 12 "and pivot pin 17, 18. The determination of such an angle of inclination is within the skill of the person skilled in the art.
  • a modification compared to the last two exemplary embodiments according to FIGS. 4 and 5 consists in the fact that instead of a single support here two support parts 12 1 , 12 2 are provided as latching element 6 ′′ here the control surface 7 "'is formed by separate vertical surfaces 7, a, 7 2 b and curved sections 7 1 c, 7 2 d.
  • the two support parts 12 1 , 12 2 are supported with the interposition of two helical compression springs 13 "', 14"' on the top of the base plate 4 "'.
  • the two support parts 12 1 , 12 2 are each by a pin, bolt or 15 ', 16', which each serve as a kind of pivot axis for the two support parts 12 1 , 12 2.
  • the two pins 15 ', 16' are fastened, for example, in the base plate 4 "'of the heel holder 1' riveted in a sheet metal wall bent from the material of the base plate 4 "', not specifically designated.
  • the two support parts 12 1 , 12 2 each have a guide 12 1 a, 12 2 b designed recess.
  • FIG. 6 corresponds to that according to FIG. 4 or according to FIG. 2, so that a further description of the design and the function should be superfluous. It should only be noted that - provided the dimensions are appropriate - the effective blocking zone can be increased compared to the previously described embodiments in that a longer path is available by pivoting the two support parts 12 1 , 12 2 than when the relative movement is exclusively in Height direction between the exclusion zone, the respective control curve and the respective role takes place.
  • the elastic support could be provided by two springs which extend in the free space on the underside of the sole holder. Or you could use a single spring attached in this area. Instead of leaf springs or helical compression springs, disc springs (or spring washers) could also be used. You could replace the metal spring material with another elastic material, such as rubber.
  • Such a configuration could take place in particular in the last exemplary embodiment according to FIG. 6, in which case, by designing the springs supporting the roller and the springs supporting the two supporting parts, the selected exemption is optionally used as in the exemplary embodiments described or briefly described below Type can be used. If the force of the two springs supporting the individual support parts is greater than the force of those springs which urge the roller downward, the roller is first pushed up in the two guides and only then are the two support parts against the force of them pressing springs pressed down.
