Definitions

  • the device for adjusting the longitudinal position of a boot holding device in a safety ski binding comprises [22] 281121313950: means for adjusting at any time the distance between l T the toe-end and heel-end boot holding means of the 1 0 binding, and also for momentary compensating the variations in said distance when running on concave [56] References Cited surface portions UNITED STATES PATENTS 3,432,180 3/1969 Suhner 280/1135 T 7 Claims, 4 Drawing Figures ADJUSTMENT DEVICE FOR SAFETY SKI BINDING FIELD OF THE INVENTION This invention relates to safety ski bindings and has specific reference to devices for adjusting the longitudinal position of a ski binding member on a ski.
  • This adjustment device in addition to its function of adjusting the sole position on the ski, may have another function, i.e. maintaining this adjustment in case of momentary longitudinal distortion of the ski itself.
  • the ski when skiing downhill on uneven surfaces the ski is not always rectilinear.
  • the weight of the skier causes the ski to be deflected momentarily and to assume a concave curvature, so that the boot length is momentarily slightly greater than the adjustment length between the toe retaining member and the heel hold-down member, as shown diagrammatically in FIG. 1 of the attached drawing.
  • the length A-C of the ski boot constitutes the chord of an are having a length A-B-C.
  • the manual adjustment of the optimum distance between the heel hold-down device and the front or toe abutment member as a function of the boot length is obtained either by using a screwdriver engaging a slot of the adjustment screw, or by rotating a knurled knob.
  • the screw is locked either by means of a knurled lock nut or by providing a well-known detent-positioning effect obtained by using a spring blade engaging the successive lateral faces of a regular polygonal member rigid with the adjustment screw. It is a primary requirement that this longitudinal adjustment manoeuver can be performed with the greatest facility when skiing under difficult conditions such as deep snow, ice, mud, and it is well known that this requirement is scarcely met in existing safety ski binding.
  • FIG. 1 is an explanatory view illustrating the operation of this invention
  • FIGS. 2, 3 and 4 of the attached drawing illustrate diagrammatically by way of example a typical form of embodiment of the invention; namely:
  • FIG. 2 is a part-elevational, part-sectional view, the section being taken along the line IIII of FIG. 3,
  • FIG. 3 is a cross-section taken along the line Ill-Ill of FIG. 2
  • v FIG. 4 is another cross-section taken along the line IV-IV of FIG. 2.
  • Means for permitting a change in the position of the ski boot engaging means along the longitudinal axis of a ski comprises a member 1 consisting of a flat plate or rack rigidly secured to the top surface of the ski 2 through known means (not shown).
  • a member 1 consisting of a flat plate or rack rigidly secured to the top surface of the ski 2 through known means (not shown).
  • One portion of this plate I has spaced notches 3 formed therein to constitute a series of rack teeth engageable by a hollow screw or member 4.
  • This screw 4 is. adapted to slide longitudinally on a prismatic rod or shaft 5 having a polygonal cross-section as shown in FIG. 3; in this example this cross-section is of hexagonal configuration.
  • Restoring means includes spring means comprising a coil compression spring 7 prestressed between the hollow screw 4 and a washer 8 retained by a circlip engaging a groove formed in said rod.
  • This spring 7 constantly urges the screw 4 against a thrust-bearing 9 rotatably mounted in the case or frame 10 of the device.
  • the prismatic rod is normally held against movement in a direction perpendicular to the plane of the ski by a pair of members 11 and 12 shown more clearly in FIGS. 3 and 4.
  • Member 11 is a cylindrical distance piece secured permanently to the case 10.
  • the other member 12 is a spring blade also secured to the case but having a thickness permitting a certain deflection in a direction perpendicular to the plane of the ski 2.
  • Said spring blade 12 comprises a central bent cavity 13 engageable by a cylindrical pivot extension 14 formed at the inner end of the rod 5, in order to prevent the rod 5 from moving in a direction parallel to the main plane of the ski.
  • These members 11 and 12 are so positioned that the rod 5 is held against translation by its engagement at 15 with the blade 12 and against rotation by the engagement at 16 of one of the flat lateral faces of the polygonal section of said rod with the adjacent generatrix of said cylindrical distance-piece 11.
  • the skier rotates the rod 5 for example by means of a screwdriver.
  • a certain resistance is encountered due to the mutual engagement of one of the flat faces of rod 5 and the cylindrical distance piece 11.
  • the user must therefore overcome this resistance by slightly bending the spring 12, the device operating somewhat like a detentpositioning mechanism, the spring resuming its initial position each time another flat face of rod 5 engages the cylindrical distance piece 11.
  • the hollow screw 4 is rotated and, by engaging and reacting against the fixed rack 3, causes a movement of translation of the complete assembly guided for example by side rails or slideways l7 and 18 formed integrally with said plate 1.
  • the prismatic rod 5 could be held against lateral movement by a step formed on distance piece ll.
  • a device for variably adjusting the distance between a toe-end and a heel-end system as a function of the length of a ski boot and for compensating for the variations normally occurring in said distance as a consequence of the momentary bending of the ski during ski runs said device comprising a flat plate fixedly mounted with respect to a ski during use of the device, an elongated rod having a polygonal cross-section and mounted for rotational movement about its longitudinal axis, means including an externally threaded member slidably mounted on said rod at one portion and coacting with said plate to move along the longitudinal axis of said ski in response to manual rotational movement of said rod, a member fixedly mounted to said rod at another portion, a compression spring interposed between said externally threaded member and said member, a fixed cylindrical member engaging said rod at one end portion and a transverse deflectable spring blade deflected in a direction vertical to the longitudinal axis of said rod in response to the rotation of said rod and rigid in
  • transverse spring blade has a central arcuate portion and wherein said rod has a cylindrical pivot at said one end portion defining an extension of reduced diameter operative to engage said central arcuate portion of said transverse spring blade.
  • a safety ski binding usable with a ski and a ski boot comprising: ski boot engaging means for releasably engaging a ski boot on a ski during use of the ski binding; means responsive to a force applied by said ski boot to said ski boot engaging means resulting from a deformation of said ski during use for permitting a change in the position of said ski boot engaging means along the longitudinal axis of said ski comprising means mounting said ski binding on said ski during use thereof for longitudinal movement therealong, an elongated shaft having a polygonal cross-section along substantially the whole length thereof; a first member fixedly mounted with respect to said ski, a second member slidably mounted on said shaft and coactive with said first member to resist longitudinal movement thereof, spring means disposed on said shaft for urging said second member towards one end portion of said shaft and for permitting said shaft and said ski boot engaging means to move longitudinally with respect to said ski whenever a force is applied to said one end of said shaft as a result of a force applied to said ski boot engaging means, and means for variably adjusting the
