Definitions

  • ABSTRACT Ski binding element supported for lengthwise adjustment on a ski.
  • a device for sup' porting a component of a ski binding such as the heel or toe component, which device is guided for movement by appropriate grooved means and is provided with longitudinally arranged adjustment teeth.
  • a similarly toothed detent, engaging by its teeth the teeth of the longitudinally movable device, is received in a transverse recess and spring urged into holding position. Pressure on the detent against the spring disengages same and the device may be longitudinally adjusted as desired.
  • the invention relates to a ski binding element which is movably supported on the ski and which can be locked in right or left directions with respect to the ski in multiple predetermined positions by means of a locking member which can be disengaged against a resilient force.
  • Swiss Pat. No. 405,129 illustrates a carriage having teeth engaged by a spring held lock.
  • the spring is here wound around a setscrew and the lock cooperates with the free end of the spring.
  • the lock itself is pulled outwardly against the force of the spring and is held in the locked condition by engagement of the spring with the teeth of the carriage.
  • the disadvantage of this known construction consists in that the teeth engage or disengage in steps in thus the release steps are relatively large.
  • French Pat. No. 2 069 874 describes a locking system which can be unlocked from the locked condition in elevating direction by means of the ski pole.
  • the locking member is flexible and engages with a single tooth the teeth provided on the guide plate. Since only one tooth element is provided as a holding member, this construction is in practice not acceptably effective. If several teeth are arranged in the longitudinal direction, then again the disadvantage already discussed above still exists.
  • Swiss Pat. No. 469 492 has as a locking element a springloaded eccentric pin.
  • the pin can be rotated in its bearing by means of its head portion.
  • the eccentricity of the pin is achieved by formation of a circular segmental cross section. If the pin lies with the circumference against the spring, then it can be moved along the rail. If, however, the straight surface of the pin lies against the spring, the locking is effected.
  • This construction has the disadvantage that only one locking is provided and further that during movement of the locking member same repeatedly falls into the recesses of the teeth on the rail.
  • French Pat. No. 2 I23 966 discloses a construction in which the spring is arranged on the one side and the operating element on the other side of the binding.
  • the guide element for the locking member consists substantially of a U-shaped bar, which is arranged transversely to the longitudinal axis of the ski.
  • the teeth of the locking member engage holes which are provided on the side of the rail, which is undesirable in view if the danger of icing-up or plugging up with snow, dirt, etc.
  • the spring which also acts with respect to such loads is, however, so strong that its storage requires much space or the operation of the locking member becomes difficult to carry out.
  • the cooperating portion of the rail must be of greater length along its sides than between the individual holes in order to be able to prevent the possibility of engagement by only one single tooth.
  • the goal of the invention is now to produce a ski binding element of the type mentioned above without the above-mentioned disadvantages.
  • the inventive construction makes possible a simple handling, namely an unlocking, adjusting and relocking merely by one hand; it survives a faulty adjustment without the danger of icing-up, of contamination or the like; and achieves a secure hold without fatigue of the spring.
  • a leaf spring is provided transversely to the longitudinal direction of the ski for acting upon the detent, both for the locking condition and for the release condition. If the toothed detent engages the toothed plate, that is, the ski binding is in a condition of use, then the springloaded forces act transversely to the longitudinal direction of the leaf spring. In this manner, the leaf spring, even when it is stressed to its maximum, is not stressed to fatigue.
  • a further advantage of the inventive construction lies in that the release requires only one elevation position which corresponds to the material thickness of the toothed plate or of the detent. This situation permits again the use of a relatively strong spring, without causing an unfavorable use of space. Finally the inventive construction permits an engagement of a uniform number of teeth of the detent through which a secure hold is achieved.
  • An advantageous embodiment of the inventive ski binding element consists in providing in the stepping or support plate a recess into which for the purpose of longitudinal adjustment a suitable tool, for example a screwdriver, can be guided.
  • a suitable tool for example a screwdriver
  • FIG. 1 is a plan view of an inventive ski binding having longitudinal adjustment and FIG. 2 is an enlarged cross-sectional view along the line ll-ll of FIG. 1.
  • FIGS. 1 and 2 disclose, a rail 2 is secured on the ski l by interpositioning a stepping or support plate 3 by means of screws 4.
  • a toothed plate 5 on which a notillustrated ski binding is mounted is movably held in the rail 2.
  • the toothed plate 5 has at one of its longitudinal sides the teeth 5'.
  • the teeth 5 are engaged by a detent 6 with its teeth 6'.
  • the teeth 5 and 6' having an equilateral triangular shape as shown in FIG. I.
  • the rail 2 is provided with a trough 7, in which there is provided a leaf spring 9 secured by means of rivets.
  • the leaf spring 9 acts upon the detent 6 to cause the teeth 6' of the detent 6 to engage the teeth 5' of the toothed plate 5.
  • the stepping or support plate 3 has a recess 10 into which for the purpose of longitudinal adjustment a suitable tool, for example a screwdriver, can be guided.
  • a suitable tool for example a screwdriver
  • the detent 6 is thus pressed downwardly against the force of the leaf spring 9 in direction of the arrow 11, so that the teeth 6 of the detent disengage the teeth 5' of the toothed plate 5.
  • the toothed plate 4 and therewith also the ski binding mounted thereon can be moved on the rail 2 into the desired position and can be there again fixed.
  • the leaf spring can be secured in the trough or the detent can be secured with the spring in various ways other than by rivets.
  • the teeth can also be constructed differently than this is illustrated in the drawing.
  • the teeth of the toothed plate and of the detent can engage deeper.
  • the recess of the stepping or support plate can be constructed differently, for example the stepping or support plate can have in this area a lateral extension for supporting or introducing the adjusting tool.
  • a device for changing the longitudinal position of a binding on a ski comprising:
  • a support plate having a flat surface thereon engaging the upper surface of said ski, said support plate having a pair of horizontally spaced and elongated ribs thereon projecting upwardly from said upper surface of said ski and extending generally parallel to the longitudinal axis of said ski;
  • an elongated rail mounted on said support plate between said elongated ribs, said rail including a bottom member, a pair of upstanding side members engaging and extending generally parallel to said ribs and an inwardly projecting flange on the upper end of each of said upstanding side members to thereby define a trough therebetween;
  • securing means for securing said support plate and said elongated rail to said ski; means defining aligned cut-outs in both of said support plate and said elongated rail; a flat leaf spring secured to said bottom member, the plane of said flat leaf spring being generally parallel to the plane of an interface between said support plate and said ski, the longitudinal centerline of said flat leaf spring being contained in a vertical plane through the center of said aligned cut-out means, said flat leaf spring extending across the width of said bottom member and into said cut-out means; binding mounting plate having a plurality of teeth along one edge thereof slidingly mounted in said trough and above said bottom member and for movement only in a direction parallel to said upstanding side members, the side of said binding mounting plate having the teeth thereon extending into said cut-out means and the bottom surface of said binding mounting plate adjacent said side having said teeth thereon being parallel with the upper surface of said flat leaf spring; and
  • said support plate has means defining a recess therein above and overlapping said flat detent member communicating with said cut-out means, said recess means being adapted to receive a suitable tool, for example a screwdriver, therein so that said flat detent member can be pried downwardly against the return spring force of said flat leaf spring.
  • a device for changing the longitudinal position of a binding on a ski comprising:
  • an elongated rail mounted on the upper surface of said ski, said rail including a bottom member, a pair of upstanding side members and an inwardly projecting flange on the upper end of each of said upstanding side members to thereby define a trough therebetween;
  • securing means for securing said elongated rail to said ski
  • a binding mounting plate having a plurality of teeth along one edge thereof slidingly mounted in said trough and above said bottom member and for movement only in a direction parallel to said upstanding side members, the side of said binding mounting plate having the teeth thereon extending into said cut-out means and the bottom surface of said binding mounting plate adjacent said side hav- 5 ing said teeth thereon being parallel with the upper surface of said flat leaf spring;
  • cutout means includes means for limiting an upward movement of said flat detent member and permitting only a downward movement relative to said binding mounting plate.
