Definitions

  • This ski binding device of the toe or heel hold-down type comprises a member for clamping or holding the toe end or the heel of the ski boot against any undesired upward movement, said member being movable vertically upwards on its support and adapted to be shifted in this direction by means of a vertically movable adjustment member on which said clamping or holding member bears in the downward direction.
  • a resilient element is interposed between an adjustment member and the clamping or holding member so as to constantly urge this last-named member downwards.
  • a position indicator associated with said adjustment member or said clamping or holding member is adapted to signal any relative upward shifting of said clamping or holding member in relation to the body of said device, against the force of said resilient element.
  • the present invention relates to ski bindings, such as toe or heel hold-down devices, which comprise-essentially a jaw or retaining member adjustable in the vertical direction for clamping the sole or heel of the corresponding ski boot.
  • toe or heel hold-down devices which comprise-essentially a jaw or retaining member adjustable in the vertical direction for clamping the sole or heel of the corresponding ski boot.
  • jaw is used throughout the following disclosure witha view to simplify the wording, but it will readily occur to those conversant with the art that this specific member may also have a shape other than that -of a jaw.
  • the jaw is pivotally mounted on its support at its end remote from the location of the corresponding boot part, and a member for adjusting the jaw in the vertical direction is provided either on said pivotal mounting or at any other suitable location.
  • This adjustment member can determine the position of the corresponding jaw by bearing thereon.
  • the boot is pressed against the ski surface, so that considerable friction develops between the boot and the ski, or between the boot and the binding member, during the operation of the device tending to release the boot.
  • an interference particularly detrimental to the proper operation of the device is observed, and this operation is obviously impaired or disturbed.
  • the bearing member engaging the holding jaw or like member constitutes at the same time the member for adjusting this holding jaw or like member in the vertical direction in relation to the boot.
  • the bearing member comprises an indicator element adapted to signal any relative movement or shift between this member and the. jaw or other holding member.
  • This indicator member may advantageously consist of 'a'visual mark adapted to move in relation to a reference mark or scale provided on the holding jaw or like member.
  • the holding or retaining jaw or like member comprises an indicator member adapted to signal visually any relative movement or shift between the bearing member and the holding or retaining member or jaw.
  • Another advantageous arrangement consists in providing on said indicator member a visual mark adapted to display the state or degree of compression of the resilient element interposed between the bearing member and the holding jaw or like member.
  • FIG. 1 is a longitudinal section showing a toe holddown device of a safety ski binding according to the present invention
  • FIGS. 2, 3 and 4 are fragmentary longitudinal sections showing diagrammatically three other forms of embodiment of the same device
  • FIG. 5 is a fragmentary vertical section showing a heel hold-down device of a ski binding according to this invention.
  • FIG. 6 is a detail view showing a modified form of embodiment of the structure shown in FIG. 5.
  • FIG. 1- is a toe hold-down device of a safety ski binding.
  • This device comprises a hollow cylindrical member 1 having a vertical axis 5 andrigid with a base plate 2 adapted to be secured to the top surface S of the ski by means of screws.
  • the body 3 of the hold-down device is rotatably mounted to this cylindrical member 1 in a plane parallel to the ski surface. The rotation of said body 3 in relation to the cylindrical member 1 can take place only against the resistance of a resilient mechanism.
  • This mechanism may consist for example of a ball 4 guided radially in relation to the axis 5 of cylindrical member 1 due to its engagement in a hole 6 formed in the side wall of said cylindrical member 1.
  • a tapered or frustoconical member 8 urged upwards in a direction parallel to said axis 5 by a coil compression spring 9 causes said ball 4 to engage likewise a V- shaped notch 7 formed in said cylindrical body 1.
  • the force of spring 9 may be adjusted by means of a screw 10 engaging a bottom plug 11 so as to compress more or less said spring 9 between the plug 11 and tapered member 8.
  • the screw 10 is rotatably mounted in said cylindrical member 1 but prevented from sliding axially therein by virtue of a relatively thick washer 12 reacting against the top of said cylindrical member 1.
  • this Washer 12 constitutes a worm meshing with an indicator member 13 guided in said body 3 or in an insert 14 fitted in said body 3 so that on the one hand it can be seen'from the outside through a window 15 formed in said body 3 or through a cover 16 also fitted in said body 3, and on the other hand said-indicator member 13 has its endxadjacent the axis 5 formed with a contour consistent with the worm-like profile of washer 12.
  • This indicator member 13 may advantageously consist of strip-like member of a suitable plastic material with one end and one side provided with notches 13a constituting teeth engaging said worm 12 due to the curvature imposed to this member 13 by its guide race or cavity formed in said body 3 and/or in the insert 14.
  • a jaw or like member 17 adapted to clamp or hold down the sole of the corresponding ski boot, by engaging the toe end of said boot in order to centre same and hold same against both vertical and lateral movements in relation to the ski.
  • the jaw 17 advantageously provided with a free passage for the screw (intended for adjusting the retaining force of the safety binding) is retained on said body 3 by a screw 18 engaging a tapped hole formed in said body 3.
  • the jaw 17 comprises a bore 19 through which the screw. 18 extends freely.
  • This bore 19 has a bottom shoulder 20 engageable by an annular portion of said screw 18.
  • this annular portion consists of a circlip fitted in a circular groove formed in the shank of said screw 18.
  • the bore 19 has an extension 22 of greater diameter constituting a seat 23 for a resilient elementengaging the head 25 of screw 18 from beneath.
  • this resilient element consists of a helical or coil compression spring 24.
  • the adjustment in the downward direction may lead to an undesired tightening of the boot sole between the jaw 17 and the top surface of the ski and/or a slip device (not shown) forming an insert on said top surface.
  • a slip device not shown
  • tightening may take place inopportunely and very easily, so to say at random.
  • the head 25 of screw 18 may be so proportioned as to project above the top surface of jaw 17 by a distance 26 (FIG. 1) for a normal and desired vertical adjustment of said jaw in relation to the boot sole.
  • FIG. 2 illustrates diagrammatically a typical embodiment of the means for displaying the proper vertical adjustment of the jaw 17 in relation to the boot sole.
  • a indicator index 27 is interposed between the intermediate resilient element (consisting in this example of a pad 24 of suitable elastomer) and the head 25 of screw 18. Normally this indicator index 27 registers with a reference mark 28 carried by the jaw 17.
  • the resilient element 24 is compressed and the reference mark 28 moves away from the indicator index 27, thus signalling a faulty adjustment that must be modified or corrected.
  • the adjustment indicator comprises a lateral or diametral pin 29 having its inner end embedded in the outer periphery of an elastic pad 24.
  • the distortion of this pad 24 by a compression due to a force F exerted on jaw 17 causes the free or outer end of pin 29 to pass through a suitable aperture 30 formed in the jaw 17 and to emerge somewhat from the outer edge of this aperture 30.
  • the indicator member consists of a deformable tongue 31 having one end secured in a circular groove 32 of screw 18.
  • this tongue is guided in a guide way 33 formed in the jaw 17 so that its opposite end be visible and can move past a window 34 so that the operator can check the proper, lowcompression adjustment of the jaw due to the provision of an indicator index 35 registering with a fixed reference mark (not shown).
  • this indicator index 35 moves away from the fixed reference mark when a force F is exerted on jaw 17 and causes a certain distortion of the elastic element
  • this invention should not be construed as being strictly limited by the specific forms of embodiment described hereinabove constituting toe hold down devices of safety ski bindings.
  • the means indicating a proper adjustment may also be applied to a heel hold-down device of which only the elements necessary for a clear understanding of this invention are shown diagrammatically in FIG. 5.
  • the body 36 of this heel hold-down device of a safety ski binding is suitably pivoted to a base member rigid with the ski and movable in relation to this base member in order to provide the desired and suitable heel release.
  • the body 36 comprises a suitable guide member having for example a dovetail contour permitting the vertical movement of a support 37 on this body 36.
  • this support 37 is adapted to properly guide in a substantially vertical direction a claw 38 constituting a hold-down member properly adapted to clamp the heel of the ski boot.
  • the support 37 carries an indicator member 41 consisting in this case of a vertical pin extending through a suitable hole formed in said body 36 so that under normal adjustment conditions the upper end of pin 41 be flush with the top edge of said hole, that is, when no compressive effort is exerted on the sole clamped between the claw 38 and the ski surface.
  • the sole is compressed to such a degree that a force F is exerted on said claw 38, the resilient or elastic element 40 is distorted to cause the indicator member 41 to emerge from the hole of body 36 and thus signal an abnormal state of compression that should possibly be modified.
  • the indicator member 41 may comprise well-defined sections 42, 43 and 44 displaying the momentary degree of compression of the sole between said claw 38 and the ski surface, for in certain cases this compression may be desirable and advantageous; especially in the case of a heel hold-down device, in order to ensure a proper holding of the boot on the ski.
  • a safety ski binding device comprising in combination a main body, means for clamping the sole or heel of the ski boot so as to hold same in the vertical direction, said means being mounted for vertical movement on said main body, an adjustment member for modifying at will the position of said clamping means in the vertical direction, bearing means for providing bearing surfaces in the downward direction for said clamping means, a resilient element acting in the opposite direction on said clamping means in order to urge same downwards, and position indicator means for indicating any relative upward movementof said clamping means in relation to the body of said binding device against the force of said resilient element.
  • a safety ski binding device as set forth in claim 1, wherein said bearing means are carried by said adjustment member and said clamping means is movable in the reverse upward direction in relation to said adjustment member, upper shoulder means being provided on said adjustment member, said resilient element being interposed between said adjustment member and said upper shoulder means of said adjustment member.
  • a safety ski binding device as set forth in claim 1, further comprising a support movable vertically, at least in the upward direction, in relation to said main body, and on which said clamping means itself is adjustable in the vertical direction, said resilient element being interposed between said movable support and port and movable in relation to said body.
