Definitions

  • This invention relates to an improved braking mechanism for a ski, comprising braking spurs movable from a raised skiing position to a lowered braking position.
  • Such ski brakes are designed to inhibit the movement of the ski down a slope when the ski is detached from a skier's boot.
  • the improvement comprises utilizing independent braking spurs having a stop means for inhibiting the movement of the braking spurs towards the longitudinal middle section of the ski when the braking spurs are in the lowered braking position.
  • the construction of the braking mechanism and independent nature of the braking spurs allows for retraction of each braking spur towards the longitudinal middle section of the ski when the braking spurs are in the raised skiing position.
  • Ski braking mechanisms generally include braking spurs attached to a common braking unit.
  • the braking unit is often a U-shaped rod having braking spurs at each end with the middle portion of the U-shaped rod attached to a brake pedal. Pivot axes for the arms extend along the middle portion of the U-shaped rod, between each braking spur and the brake pedal, allowing for pivotal movement of the braking unit.
  • the brake pedal is urged in an upwards direction by a spring mechanism when the ski is detached from the skier's boot. This upwards movement of the brake pedal results in pivotal movement of the braking spurs from the raised skiing position to the lowered braking position. In the lowered braking position, the braking spurs inhibit the movement of the ski down the slope, thus avoiding the necessity of utilizing an ankle safety strap. The dangers of such safety straps are well known.
  • Braking mechanisms as described above have disadvantages.
  • the braking spurs When in the raised skiing position, the braking spurs extend laterally from the ski and are essentially parallel to the edge of the ski. This lateral extension, although generally only slight, results in some contact between the braking spurs and the snow even when the spurs are in the raised skiing position.
  • skiing performance is somewhat impaired by the additional resistance created by the braking spurs, particularly when skiing in deep snow or when the ski is not flat against the snow, as in turns. Additionally, the contact results in unnecessary wear on the braking spurs.
  • the braking spurs have a tendency to move towards the longitudinal middle section of the ski while in the lowered braking position. This results in decreased effectiveness of the braking spur.
  • the braking spur generally comprises a metal rod, at the end of which is often positioned a spur cap, preferably of injection-molded plastic. The lower portion of the end of the spur cap is often substantially hook-shaped. The inwards motion of the braking spur can result in the hook-shaped spur cap either hooking the lower longitudinal edge of the ski during braking, or angling out of its position of maximum effectiveness for braking the ski.
  • the present invention overcomes shortcomings of the foregoing other bindings.
  • the invention in its preferred form comprises a pair of Z-shaped, independently movable rods, each having an outer leg forming a braking spur and an inner leg attached to a brake pedal, and a central cross-bar forming a pivot axis.
  • the independent movement of the braking units allows each braking spur to be retracted towards the longitudinal middle section of the ski when the braking spur is in the raised skiing position. In this manner, the braking spurs will not inhibit the motion of the ski and wear on the braking spurs is minimized.
  • the preferred embodiment of the invention further includes a stop for inhibiting the inwards motion of the braking spurs while in the lowered braking position.
  • the stop does not inhibit the inwards motion when the braking spurs are in the raised skiing position.
  • the stop may be formed on the cover plate of a bearing housing and may comprise flanges designed to inhibit sideways movement of the Z-shaped braking rods when the braking spurs are in the lowered braking position.
  • this braking mechanism is simple and it can be produced inexpensively.
  • the drawing is a top view of a ski brake according to this invention with the top half illustrating a ski brake in the raised skiing position and the bottom half illustrating a ski brake in the lowered braking position.
  • the drawing shows the top view of a braking mechanism according to this invention.
  • the top half of the drawing shows the braking mechanism in its raised skiing position, while the bottom half illustrates the lowered braking position.
  • a braking mechanism utilizing two Z-shaped rods and two braking spurs one on each side of the ski, a braking mechanism utilizing one braking spur is also within the scope of the invention.
  • the braking mechanism has a base plate 1, which is fastened to a ski 3 by means of screws 2.
  • the entire base plate is not shown in the drawing, rather it illustrates only the left half of the base plate.
  • the right half of the base plate contains holding bars, guide bars, and the sole-holder, which are not aspects of this invention.
  • the mechanism has two braking spurs 4, 5, each the outer legs of two Z-shaped rods.
  • the rods further include a pair of inner legs 8, 9 which may be angled towards each other at the ends and attached to a brake pedal 16 in a manner allowing for pivotal movement of the angled ends.
  • the ends of the inner legs 8, 9, if angled towards each other, may be flexibly joined.
  • the base plate 1 and a cover plate 10 from a bearing housing.
  • the cross-pieces of the Z-shaped rods form pivot axes 6, 7.
  • These pivot axes 6, 7 are held between pairs of rivets 11 which inhibit the movement of the pivot axes 6, 7 in the lengthwise direction of the ski 3.
  • the rivets 11 stand perpendicular to the surface of the ski.
  • Each rivet 11 is attached to its upper end to the cover plate 10 and at its lower end to the base plate 1.
  • Into the cover plate 10 is molded a flange 12 which forms the stop according to this invention.
  • the flange 12 When the braking spurs 4, 5 are in the raised skiing position, the flange 12 does not inhibit movement of the spurs 4, 5 toward the longitudinal middle section of the ski, as illustrated in the top half of the drawing. However, when the braking spurs 4, 5 are in the lowered braking position, as illustrated in the bottom half of the drawing, the flange 12 inhibits inward movement of the pivot axes 6, 7, thus inhibiting inward movement
  • the cover plate 10 has a slot 13, dividing the flanges 12.
  • the slot 13 allows for the passage of a coupling member 17 which is pivotally attached at one end to the base plate 1 and at the other end to the brake pedal 16.
  • the coupling member is substantially parallel to the surface of the ski 3.
  • a spring 18 is attached to the base plate 1 and is positioned perpendicular to the lengthwise direction of the ski 3 and parallel to the surface of the ski 3. The spring 18 urges the coupling member 17 and, thus, the brake pedal 16 in an upwards direction when the ski 3 is detached from the skier's boot.
  • the inner legs 6, 7, attached to the brake pedal 16, are also urged in an upwards direction, resulting in pivotal movement of the braking spurs 4, 5 to the lowered braking position.
  • a means is provided for urging the inner legs 8, 9 in a manner that causes the braking spurs 4, 5 to move towards the longitudinal middle section of the ski when the braking spurs 4, 5 are in the raised skiing position.
  • This urging means may be guide bars 19, 20 attached to the bottom of the brake pedal 16. The guide bars 19, 20 only engage the inner legs 8, 9 when the braking mechanism is in the skiing position.
  • Spur caps 14, 15 are attached at the free ends of the braking spurs 4, 5 and increase the braking surface of the braking spurs 4, 5. These spur caps 14, 15 are preferably of injection-molded plastic, although other materials are appropriate. The lower portion of the ends of the spur caps 14, 15 may be substantially hook-shaped to provide additional braking efficiency when the braking spurs 4, 5 are in the lowered braking position.
  • the stop may merge into a guide track, which runs toward the longitudinal middle section of the ski.
  • the guide track allows for a smooth transition of the braking spurs 4, 5 from the raised skiing position to the lowered braking position when the ski is detached from the skier's boot.
