Definitions

  • ABSTRACT A braking device for a ski to stop its eventual escaping, comprising a braking unit adapted to be moved, due to an unexpected separation of ski and ski-boot, from a resting position flush with the ski trunk into a braking position by spring action, in which position a member of the braking unit projects beyond the sliding surface of the ski trunk in a transverse direction thereto, the braking unit being releasably held in resting position by a disengageable release element preventing the spring action only in engaged position and being disengageable by the separation of ski and skiboot.
  • a braking device on a ski comprising a braking unit which snaps into the braking position every time the ski-boot in detached from the binding, that is to say, even when the ski is taken off in the normal way.
  • the braking unit must be restored each time into its resting position, this being again a disadvantage.
  • a braking device is mounted on the ski trunk, which comprises a releasably locked braking unit being submitted to tensioned spring means for moving the released braking unit from its resting position flush with the top of the ski trunk into its braking position in which a braking member of the unit projects beyond the sliding surface of the ski trunk in a transverse direction thereto, a disengageable release element being provided to lock the braking unit in its resting position and being adapted to be brought in pulling connection with the ski-boot or leg of the skier, so as to because disengaged by an unexpected separation of the ski and ski-boot.
  • FIG. 1 is an elevational lengthwise view of a first embodiment of the braking device with parts of the ski trunk and ski-boot;
  • FIG. 2 and 3 are each a top view of the braking device of FIG. I, seen in its resting and braking positions, respectively
  • FIG. 4 and 5 are an elevational lengthwise view and a top view, respectively, of a second embodiment of the braking device;
  • FIG. 6 to 9 show additional embodiments or modifications of the braking device, each in elevational view and in top view, respectively.
  • the wing In resting position, the wing engages with its end 9 which is opposite to the hinge 6 and bent slightly downwards, beneath the upper wall 10 of a housing 11 provided on the base plate 2.
  • a tension spring 12 is arranged perpendicularly to the pin 3 and engages the plate 4 for turning it in counterclockwise direction about the pin 3 into the operating position shown in FIG. 3.
  • the resting position there is an interspace between the braking wing 5 and the rear wall 11' of the housing 11, in which space a spherical release element or ball 14 is clamped by the action of the spring 12 and is fastened to a rip-wire 15 which permits the ball 14 to be torn out of the device.
  • the ball 14 In its engaged position, the ball 14 is partially inserted into a concave part 13 fastened on the plate 4 so that a disengagement of the ball by itself is not possible.
  • the swivelling plate 4 accordingly is somewhat displaced, so that the braking wing 5 with its bent end 9 at the housing wall 10 is pressed against two buffers 4' on the plate 4, and this action shatters any ice that may have formed there and that could impede the functioning of the device.
  • the plate 4 together with the wing 5 is turned by the tension of spring 12 into the operating position shown in FIG. 3.
  • the wing 5 with its end 9 is swung away from the wall 10 and is opened up by the torsion spring 8 into the braking position wherein the wing 5 extends considerably beneath the plane of the sliding surface of the ski trunk 1 in a transversal direction thereto.
  • the rip-wire 15 of the release ball 14 can be detachably connected, for example by means of a spring snap 16, to a ring 18 fastened on the leg portion of the skiboot l7, and this is done upon stepping with the boot into the ski-binding; it can be easily detached again before stepping out of the binding.
  • a pawl 30 formed by a leaf spring is mounted on the lower side of the plate 4 and extends beneath the axle 7 where the pawl nose 31 is downwardly directed for engaging the wing 5 at a rim 32 adjacent to the axle 7 as soon as the wing reaches its braking position. If the wing 5 is to be restored into the resting position, the pawl nose 31 must be disengaged from the rim 32 by pressing the pawl slightly against the plate 4.
  • the braking wing 5 is held down on plate 4 in resting position by a permanent magnet 19 fastened onto plate 4.
  • the wing 5 has a projection 20 which overlaps the release ball 14 being set in place between the end of plate 4 and the rear wall 11 of the spring housing 11. This is to prevent plate 4 from being subjected to the tension of the spring 12, and wing 5 from swinging out.
  • a narrow housing wall 21 allows the ball to emerge only in upward direction, so that in this way the braking wing 5 with the projection 20 is displaced upwards, this breaking the magnetic contact with the plate 4, so that the torsion spring 8 will open up the wing 5, while simultaneously the plate is swung out about the pin 3 by the tension of spring 12.
  • FIG. 6 and 7 differs from the embodiment just described only in that instead of the magnetic connection between the wing and the plate 4, there is fixed to the latter a snap-bolt 22 held in locked position by a screw-spring 23, in which position the lower edge surface 24 of the bolt 22 engages a correspondingly inclined tongue 25 of the wing 5.
  • the tearing out of the release ball 14 displaces the projection with the rest of the braking wing 5 upwards, so that the bolt 22 recedes from the tongue 25 and releases the wing.
  • FIG. 8 and 9 there is affixed on the base plate 2 a catcher 27 against which the projection 20 of the braking wing 5 abuts in its resting position under the tension of spring 12, thus preventing the plate 4 from swinging out about the axial pin 3.
  • the top of the catcher 27 forms a resilient nose 28 which overlaps the projection 20 for preventing an opening up of the wing 5 by itself.
  • the release element is constituted by a ring 14 which is loosely pushed on the pinlike projection 20 and is connected by a non-visible wire with the leg portion of the ski-boot as is the ball 14 according to FIG. 1.
  • a braking device for stopping the escape of a ski comprising a base piece mounted on an upper side of the ski; a pivot fixed in said base piece and projecting upwards therefrom; a braking unit including a support member pivotally mounted on said pivot and a braking member hinged to said support member and adapted to lie thereon in resting position and to be displaced into a braking position wherein said braking member projects downwardly beyond the sliding surface of the ski, first spring means connected between said support member and said braking member for resiliently urging the latter into said braking position, a catch retaining said braking member in resting position against the action of said first spring means, second spring means connected between said base piece and said support member for resiliently urging the latter to an operative position permitting said braking member to move to said braking position, and a stop on said base piece for maintaining said support member against movement to said operating position under the urging of said second spring means; a releasing element normally engaging and maintaining said braking member against displacement to said braking position; and means connected with said releasing element
  • a braking device as claimed in claim 1 a resilient pawl being mounted at the bottom side of said support member and engaging said braking member adjacent to its hinged end in braking position against any outer force counteracting the force of said first spring means.
