Definitions

  • My invention has for its object a so-called safety securing system for skis, said system being of the type including instead of the conventional strap, a pivoting abutment against and underneath which the front end of the shoe is engaged so as to allow releasing the skiers foot in case of a dangerous twisting of the skiers leg.
  • some include an abutment designed in a manner such that its pivotal movement in the opening direction is accompanied by a translational forward movement through which movement the cable or the like element holding the shoe against the abutment is suddenly released, which furthers the release of the shoe and increases consequently the safety,
  • My invention covers more specifically a securing system of this type wherein said association of a pivotal movement with a translational movement is obtained through the novel application for this purpose of the properties of two isosceles or equilateral triangles inscribed one inside another, one of said triangles being stationary and the other being held fast against translational movement by reason of the apices of the inner triangle engaging the sides of the outer triangle, while said other triangle may however revolve and execute then a translational movement as soon as the contact between the three apice of the inner triangle and the three sides of the other triangle is cut out.
  • one of the triangles is rigid with the abutment while the other is formed on the plate secured to the ski, the inner triangle being rigid either with the abutment or with the securing plate on the ski while the outer triangle may be formed by a recess provided correspondingly in the securing plate or in the abutment respectively.
  • the inner triangle rigid with the abutment is constituted in practice by three small parallel pins arranged at the three apices of a geometrical triangle and carrying three rollers which, when the securing system is closed, engage the three corresponding sides of a triangular housing formed in the carrier plate secured to the ski, said rollers running over said sides when the abutment pivots and moves translationally during the opening and closing stages of the securing system; of course elastic means are provided for holding the abutment in its normal position on the plate secured to the ski as long as no exaggerated lateral stress is exerted on said abutment.
  • the pins carrying the rollers on the abutment are interconnected by a small plate of which the periphery engages and slides over a flange in the triangular housing of the carrier plate.
  • the sides of the triangular housing formed in the carrier plate may, in the case of the embodiment described hereinabove, be no longer rectilinear but curvilinear, the two lateral sides being for instance inwardly convex while the transverse side is inwardly concave.
  • FIGS. 1 and 2 are diagrammatic views of the securing system respectively in its closed and in its open position
  • FIGS. 3 and 4- how two modifications in the execution of the principle underlying the invention
  • FIGS. 5, 6 and 7 are views from above of a safety abutment designed in accordance with the same principle and illustrated respectively in its normal condition of use, at the beginning and at the end of its pivotal movement,
  • FIGS. 8 and 9 are a corresponding view from underneath and a longitudinal sectional view through line 99 of FIG. 8, for the normal position illustrated in PEG. 5.
  • the carrier plate 2 is provided with an opening 4 having a triangular shape while the abutment 3 is rigid with an upright 5 the crosssection of which is also triangular, the arrangement being such that the two triangles may be inscribed one inside the other, as illustrated in FIG. 1.
  • the apices of the inner triangle 5 are in contact with the sides of the triangular opening 4 so that the abutment 3 is hold fast longitudinally and transversely with reference to the stationary plate 2.
  • the only relative movement between said two parts is allowed by a rotary movement of the upright 5, which movement is braked by adjustable elastic means 6 fitted between said abutment and the plate 2.
  • the upright 5 pivots inside its triangular opening 4.
  • the two triangles being no longer inscribed one inside the other, the pivotal movement of the upright 5 is accompanied by a forward translational movement thereof inside the plate 2, as illustrated in FIG. 2.
  • the contact between the abutment and the stationary plate is advantageously ensured as shown in FIG. 3 by three rollers 7 distributed along the apices of a geometrical triangle 8 which may be inscribed within the triangle formed by the opening 4 in the plate 2.
  • Last-mentioned triangle may in fact form a true triangle, that is, it may be provided with rectilinear sides or else assume only a generally triangular shape and have curvilinear sides, to wit for instance two longitudinal sides 4a and 4b which are inwardly convex and a transverse side 4c the concavity of which faces inwardly as readily apparent from inspection of FIG. 4.
  • FIGS. 5 to 9 illustrate with greater detail a safety abutment incorporating the above-described arrangement.
  • the abutment includes a main body 3 screwed over a plate 11 serving as a support for three pins arranged at the apices of a geometrical isosceles triangle.
  • Each pin 9 carries a roller 7 and the lower ends of the three pins 9 are interconnected by a small plate 10, a fraction of the periphery of which engages a recess formed in the edge of the openings 4 just above the lower surface of the plateiZ'.
  • the front section of the abutment body 3 is provided with a vertical tapped recess inside which is screwed a screw with a knurled head 13 exerting through the agency of a spring 14 an adjustable pressure on a ball 15 projecting from the plate 11 and engaging a recess 16 in the shape of a spherical cup formed in the front end of the supporting plate 2.
  • the outline of the abutment 3 is pro vided (FIGS. 5 to 7) with two dovetailed sections 17 and a V-shaped section 18 in which sections are fitted corresponding outline sections formed on the front surface of a member 19 which holds the tip of the skiers shoe in position.
  • Said member 19 may be shifted vertically with reference to the abutment body 3, so as to allow an adjustment of its level by the screw 21 as required by the thickness of the shoe sole.
  • the abutment 3 When the securing system is in its normal position use (FIGS. 5, 8 and 9), the abutment 3 is held symmetrically to either side of the longitudinal axis of the plate 2 and of the ski by the ball 15 which engages the recess 16 in said plate 2. Any shifting of the abutment body 3 towards the front or the rear or laterally with reference to the plate 2 is prevented by' the rollers 7 a number of which engage the convex edges 4a and 4b of the opening 4 while the others engage the concave edge 40 of said opening.
  • the abutment including the body 3 and the member 19 moves with reference to the supporting plate 2 upon elastic release of the ball 15 out of the recess 16.
  • Said shifting of the abutment with reference to the supporting plate 2 is accompanied by a rolling of the rollers 7 along the sides of the opening 4 and it includes not only a pivotal movement but also a translational movement of the abutment with reference to the plate 2.
  • Said compound movement is produced by the shifting of the rollers 7 in the opening 4.
  • the abutment body 3 and member 19 assume thus a very speedy rotary and forward translational movement, which movement appears from inspection of FIGS. to 7. Said movement allows a practically instantaneous release of the skiers shoe out of the securing system.
  • said securing system is readily returned to its closed position through a mere handoperated shifting of the abutment 3 until the ball engages again its recess 16.
  • the outline of the opening 4 in the plate 2 cooperating with the rollers 7 of the abutment, makes it a particularly easy matter to return the securing system to its original condition.
  • my improved securing system shows the advantage of showing a jaw constituted by the member 19 on the abutment, of which jaw the level is adjustable and of which the V-shaped outline section engaging the abutment body 3 compensates automatically for any clearance which may be formed between the jaw and the abutment body.
  • a safety system comprising a plate rigidly secured to the ski, an abutment engaged normally by the tip of the skiers shoe, and a connection between said abutment and said plate including means defining a triangular recess having two equal sides and rigid with one of said plate and abutment, a triangular member having two equal sides and being rigid with the other of said plate and abutment and the apices of which engage the corresponding sides of the triangular recess in the normal position of the abutment with reference to the ski, said apices and said triangular recess being so disposed that the rearward thrust of said plate on said abutment is shared substantially equally by two said apices, said apices being shifted away from said engagement upon excess angular thrust of the shoe against the abutment to thereby release said triangular member and allow a combined angular and longitudinal movement of the abutment with reference to the plate, and means yieldably retaining the triangular member in said normal
