Definitions

  • the object of the present invention is a boot centering and forward thrust applying device for a ski safety harness.
  • This device differentiates from the known devices by the fact that it simultaneously ensures the centering of the heel of the boot on the ski and applies a horizontal forward thrust on the said boot, pressing the latter against a forward abutment.
  • Another object of this invention consists in the provision of a simple device which can be used independently or in combination with a vertical holding member for a rear holding device, or with any type of safety rear abutment.
  • the device comprises two means, independent or in combination, applying on the rear edge of the heel of the boot, two substantially equal inclined lateral forces, the resultant of which is a forward directed thrust, substantially along the longitudinal axis of the ski, the said forward thrust ensuring a constant pressure of the boot against the front abutment.
  • the two means providing the inclined lateral forces are advantageously constituted by two movable arms which spread when the boot is inserted in the harness while causing elastic means to react in an inclined lateral thrust.
  • the two means to provide the oblique lateral thrust of the device are constituted by two adjustable arms which can move substantially in a longitudinal direction, respectively on one or the other lateral side of the rear abutment of the safety holding device. Flexibility in the gripping of the heel is obtained through the elasticity of the sole of the boot, when the two thrust means are rigid, or by the elasticity of the said thrust means.
  • the elasticity of the said thrust means may be the result of steel springs or elastic assembly of the rear holding device by means of springs, rubber blocks or similar devices.
  • FIG. 1 illustrates the principle of the centering device having a forward horizontal thrust for a safety rear holding device.
  • FIGS. 2, 4, 5, 6, 8, 9, 10, 12 and 14 are plan views of various embodiments of the centering device.

  • FIG. 20 is a perspective View of a centering and boot heel thrust applying device according to a different embodiment.
  • FIG. 1 two substantially equal oblique lateral forces shown by arrows 3 and 4 are applied through appropriate means on the rearward edge 1 of the heel 2 of the boot.
  • the result is that the boot is pushed forwardly on the ski, substantially along the longitudinal axis of the said ski, said push being illustrated by arrow 5, the boot resting against an abutment in front of the boot.
  • the heel 2 of the boot is automatically maintained in a centered position on the ski.
  • the two oblique lateral forces, along 3 and 4 of FIG. 1, acting on heel 2 of the boot, are obtained through two arms 8 of a leaf spring 10.
  • Each arm 8 comprises a wing 12 bent at its upper part, as particularly shown in FIG. 3, allowing,
  • the heel 2 to spread the branches 8 of the leaf spring by causing the branches 8 to open.
  • the two oblique lateral forces 3 and 4 of FIG. 1 are obtained by the pulling action of the two branches 8 and the spring 10, the latter being in an opened position.
  • the embodiment shown in FIG. 2 is particularly simple and economical.
  • the two lateral inclined forces 3 and 4 of FIG. 1, acting on heel 2 of the boot are obtained by two levers 25, hinged around two axles 26, comprising each an arm 27 bent at its upper part to facilitate insertion of the boot, heel 2 automatically spreading the said levers 25.
  • Levers have a tendency to come together around pivotal axle 26 through a leaf spring 28 retained by a support 29 by means of a rivet 30.
  • Each lever 25 comprises a toothed sector 34, in mesh with a similar section 34 of the other lever 25, allowing an automatic centering of heel 2, the two levers 25 opening and closing along identical opposed angular amplitude.
  • the two oblique lateral forces 3 and 4 of FIG. 1 acting on heel 2 are obtained by means of two leaf springs 30 fixed to ski 31 by means of screws 32, springs 30 bent at an angle appreciably over 90, whose upper part 33 is also bent, as particularly shown in FIG. 7.
  • heel 2 takes place between the two bent parts 33 and spreads the two free extremities of the leaf springs 30.
  • the force acting upon the two free extremities whch are under tension ensures the centering of the heel 2 on the ski 31 and its forward thrust substantially in the longitudinal axis of the said ski 31.
  • the two oblique lateral forces 3 and 4 .of FIG. 1, acting on heel 2 are obtained. by means of two levers 40, hinged around two axles 41, and pulled together by pivoting around the axles 41, through a leaf spring 42 under tension, in the engaged position of the heel 2.
  • Each lever comprises, in addition, an arm 44 bent at its upper part, facilitating the engagement of the 0 heel 2 when the boot is inserted in the device.
  • the device represented in FIG. 9, differentiates from the one shown in FIG. 8 only in that the two oblique lateral forces 3 and 4 of FIG. 1, acting on heel 2, are obtained by means of two levers 50, similar to 40 of FIG. 8, hinged around a single axle 52.
  • a leaf spring 53 tends to pull together, by pivoting around axle 52, the two levers 50 comprising each an arm 55, folded at its upper part in a manner to facilitate the insertion of the boot in the device.
  • the two oblique lateral forces 3 and 4 of FIG. 1, acting on heel 2 are obtained by means of two levers 60, substantially vertical, hinged at one end on a support 61, for example fixed to ski 62, around an axle 64, the levers 60 being caused to rock in the direction shown by 65 (FIG. 11), causing the free ends to come together, to a compression spring 68 under tension between on one side, each lever 60, land on the other side, the bent end 70, substantially vertical, of the corresponding support 61.
  • the free end 71 of each lever 60 is bent in a manner to ease engagement of heel 2 in the device.
  • the two oblique lateral forces 3 and 4 of FIG. 1, acting on heel 2 are obtained by means of two sliding parts 80 horizontally guided by means of a bent foot 82 sliding between a support 83, for example fixed to the ski 84, and a plate 85 securely fixed to the said support 83 by means of a screw 86, as particularly shown in FIG. 12.
  • the said sliding parts 80 tend to slide in the direction 88, causing the said parts to come closer together, by means of a compression spring 89 located between flange 81 of each sliding part 80 and a bent end 90, generally vertical in relation to the corresponding support 83.
  • the free end of each sliding part 80 is bent as at 91 in a manner to facilitate engagement of the heel 2 on the device.
  • the two lateral inclined forces 3 and 4 of FIG. 1 acting on heel 2 are obtained by means of two traction coil springs 94, each under tension between a common gripping post 95, located in the longitudinal axis of the ski at the rear of heel 2, and a second post 96, laterally located in relation to the said heel 2.
  • heel 2 comes in contact with the inner part of coiled springs 94, inside the acute angle formed by the two longitudinal axes thereof, pushes the said springs outwardly to allow free passage for heel 2.
  • the latter after engagement, is properly centered and under a forward thrust, the two springs 94 being under lateral tension.
  • the two oblique lateral forces acting on the heel 2 of the boot are obtained by means of two arms 100 comprising two bent flanges 101 resting on the said heel 2.
  • the two arms 100 are fixed to the outer casing 104 of the rear abutment of the safety holding device 105.
  • arms 100 can be moved and locked in a direction generally along the longitudinal axis of the ski, thereby making the invention usable on various types of boots, by means of ridges 106 located on the inner face of the said arms 100 coming in contact with the ridges 108 formed on the lateral sides of the casing 104 of the rear abutment, stability in the desired adjusted position being obtained by means of a screw 110, advantageously provided with a washer 111, the screw 110 passing through a slot 112 and fixed to the casing 104.
  • the arms 100 may be rigid, the flexibility of the gripping of the heel 2 being obtained by the elasticity of the sole of the boot, or they may be resilient, for example, made of spring steel, giving an automatic fiexibility to the gripping means.
