Definitions

  • the distance between the extremities of the concave opening in the block not only prevents immediate disengagement of the boot the moment the block begins its rotation, but also makes it necessary for the said boot to move rearwardly which, when this is not possible, causes the safety device to jam, or, when it is possible, retards and seriously interferes with its operation.
  • the thrust block of the present invention has for its object to obtain, whilst retaining a remarkably low cost price resulting from great ease of manufacture and machining, a practically immediate disengagement of the block as soon as it has left its normal position of use .on the fixing device under the elfect of a particularly violent force, a position in which his normallymaintained by means of a trigger of known type, which may be adjustable by spring and ball (or other means).
  • the rapid retraction of the block will be obtained by the provision that its pivotal support is capable of sliding, either with respect to said block, or with respect to its support, this sliding motion enabling the immediate freeing of the boot.
  • a stop-pin in the latter bears against a corresponding stop-pin of the supporting plate fixed to the ski, preventing the thrust block from sliding forwards in the slot provided for this purpose, this sliding motion however becoming possible again upon non-alignment of the stoppins as soon as the block moves from its normal position, .immediated disengagement thus being provided.
  • the notches of the thrust-block destinedto prevent any'lateral slipping of the boot are placed along an arc of a circle substantially centered on the normal pivotal axis of the block, and would in addition andwith advantage be provided'with clearances towards the inside of the are, in order to exclude all possibility of binding against the boot.

  • Fig. 11 is a partialview in perspective of the-immobilizing componentsof the block according to Fig. 10.
  • Fig. 16 is a view in elevation of the said block, out
  • Figs. 17 and 18 are schematic views from below show- .ing the composition of the forces at the level of the stoppins of a block and its support, identical to those according to Figs. 15 and 16.
  • Fig. 19 is a schematic view from below of a variant .for the stop-pins of the block and its support, identical to those according to Figs. 15 and 16.
  • a supporting plate 1 is fixed to ski 2 by means ;of screws 3 and includes a stop-pin 4 obtained for example by bending upwards the sheet-metal constituting plate 1.
  • the body 5 of the block receives the end 6 of jthe boot with which it remains normally in engagement by means of notches 7 designed to avoid any lateral slipping, and lips 8 of the block are designed to prevent the boot from moving upwardly.
  • the body 5 of the block is provided with a slot 9 through which extends a bossed pivot screw 10 which serves for assemblage of .the block to the supporting plate 1.
  • a stop-pin 11 fixed to the body 5 of the block rests normally against the corresponding stop-pin 4 of the supporting plate 1 under the action of the force 12 exerted by the toe 6 of the boot, this force resulting, for example, from the action of
  • the means for example, of a ball trigger of known type, its position 13 only being shown on the drawing, a cavity be- .ing provided in the supporting plate 1 for the catch.
  • the stop-pin 4 projects above the upper face of the supporting plate 1, the length of stop-pin 11 of the body 5 of the block being such that it can in no case come into contact with said upper face of the supporting plate '1.
  • the safety block will operate in the following manner: when the boot exerts a torsional stress in the direction of arrows 14 or 15 sufficient to disengage the trigger .ball lodged at 13, body 5 of the block will rotate as shown by arrows 16 or 17, describing an extremely short are .around the pivot screw 10, an arc which is insufficient to cause binding of the edges 18 and 19 of body 5 of the block against the toe 6 of the boot, and following which stop-pin 11 will no longer engage stop-pin 4; the
  • body 5 of the block will then be free to give way to the pressure exerted in the direction of arrow 12 by the boot,
  • Figures 2 and 3 show a preferred embodiment of the invention, in which the supporting plate 1 fixed to the ski 2 by means of screws 3 comprises a stop-pin 4 .
  • a stop-pin 4 .
  • Fig. l and is provided, by means of a bossed pivot-screw 10, with a thrust-block body 5.
  • This body comprises, as in Fig. 1, notches 7 and lips 8 designed to immobilize the toe of the boot, as well as a stop-pin 11 which works with the stop-pin 4 of the supthrough the intermediate shell 22 destined to reduce the friction between the sliding or rotating surfaces.
  • the immobilizing and positioning ball trigger 23 in body 5 of the thrust-block is, in normal conditions of use, disposed in cavity 13, which is situated with respect to pivot-screw 1th on the side opposite to the zone of contact of thrustblock body 5 with the toe of the boot, in such manner that the pressure of the spring 24 of the ball-trigger 23 against the supporting plate 1 should tend to balance, with respect to said pivot-screw 10, the pressures which may be produced in the direction of arrow 25 by the edge of the sole of the boot against the lips 8 of the thrust-block body 5.
  • the ball-trigger 23 is provided with a shoulder 65 which prevents it being ejected when the rotation of the thrust-block body 5 has disengaged said ball-trigger from its rest against the supporting plate 1.
  • the bevelled edge 26 of the supporting plate 1 enables the ball-trigger 23 to move upwards into cavity 13 as the thrust-block body 5 is returned to its normal position of use, the operation of the whole being otherwise identical to that described for Fig. 1.
  • clearance 27 provided in the thrust-block body 5 permits the free passage of stop-pin 4 under said body 5; and also that the stop-pin 11, which can with advantage be a simple taperpin driven into the thrust-block body 5, is of such length that its visible extremity will not enter into contact with the upper face of supporting plate 1 during operation.
  • the head 21 of pivot-screw permits sliding and rests against the bottom of groove 28 provided for this purpose in the thrust-block body 5, and opposes the wrenching forces applied to said body 5 by the spring 24 and the forces in the direction of arrow 25 from the toe of the boot.
  • a plate 29 fixed to the thrust-block body 5 by means of the two screws 30 encloses the space housing the pivot-screw 10, formed by slots 9 and 28, and enables this space to be filled with grease which eases and maintains correct operation of the thrust-block.
  • the embodiment variant represented in Figs. 4 and 5 differs from that of Figs. 2 and 3 only by the position of ball-trigger 23 situated in its housing 13 in the thrustblock body 5, between the pivot-screw 10 on the one hand, and the notches 7 and lips 8 destined to receive the toe of the boot on the other hand, said lips 8 being divided into two parts in identical manner to those represented in Fig. 1 and Fig. 2.
  • Figures 6 and 7 represent a variant which differs from that described in Figs. 2 and 3 only by the inversion, with respect to pivot-screw 10, of the respective positions of ball-trigger 23 and the stop-pins 11 of thrust-block body 5, and 4 of supporting plate 1, these stop-pins being situated at the extremity of the thrust-block opposite to that destined to receive the toe of the boot.
  • a sleeve 35 is provided coaxial with the pivot-screw 31 and engaging with the inner surface thereof the boss of screw 31 and with the outer surface thereof the slot 32 so as to reduce friction during movement of the thrust-block body 5.
  • a stop-pin 11 in the thrust-block body 5 will cooperate, as previously, with the stop-pin 4 carried by plate 34, but because of its length it will not be able, during the displacement of the thrust-block body 5 in direction of arrow 20 forwardly on the ski, to pass over thesupporting plate 34,
  • Thrust-block body 5 is provided, as previously, with a ball-trigger in housing 13, positioning the said thrust-block body, .the ball-trigger locking in a corresponding recess in the intermediate :plate 33 fixed to the supporting plate 34.
  • the operation of this em bodiment will be identical to that of the abovedescribed embodiments, with the exception that the thrustblock body 5 will not be able to return, during operation and after disengagement of the stop-pins 4 and .11, to the position in which its longitudinal axis is parallel to that which said axis occupied before disengagement, because of the respective characteristics of stop-pin 11 and plate 34. It is evident that it is possible, as in the case of the preceding embodiments, to adopt various relative positions for the -stop-pins, the ball-trigger, etc,, with respect to the pivot screw of the thrust-block body.
  • Figures and 11 illustrate the replacement, according to a particularity of the invention, in a thrust-block otherwise identical to that described in the .preceding Figs. 2 and 3, of the stop-pin system-4 and 11 by a trigger 39 with a shoulder 40, particularly illustrated in Fig. 11, which provides, in addition to its known positioning elfect, the restraining action which devolved precedingly .to the said stop-pins.
  • This trigger is fitted in housing 13 of the thrust-block body 5 and engages in a slot (orother recess) 41 in the supporting plate 42, attached to the ski .2 by the screws 3, said itrigger being prevented from rotating in its housing 13 by appropriate means (key- -pin, etc.) notillustrated.

  • the stop-pin 11 of the thrustablock body 5 will rest against extremity 53 of plate 50, which takes the place of stop-pin 4 of plate 34 in Fig. 8.
  • notches 7 on its body 5, with the intension of preventing lateral movement of the boot, the extremity 6 of which engages underthe lips 8 with said notches.
  • These notches 7, say three for example, are disposed along the arc of a circle 60 which has substantially for its center the axis of pivot-screw 10, in the positionof use of the thrust-block.
  • the lip 8 is shaped so that during operation of the thrust-block, it will at no moment come into contact with the upper part of the boot, and the substance of the (thrust-block body is limited towards the extremity 6 of the boot, with the exception of the lip v8, by clearances 67 and 68 recessed behind the arc of circle '60 positioning notches 7, on either side of the latter, in
  • the stop-pins 11 of the thrust-block body 5 and 4 of-the supporting plate 1 have the shape more particularly apparent in Figs. 15, 17 and 18, as well as in Fig. 19. I
  • the stop-pin 11 of the thrust-block body 5 is of cylindrical shape-and rests on an edge or" stop-pin 4, of prismatic shape, integral with the supporting plate 1'; both stop-pins being identical to those illustrated in Fig. 15.
  • the force '12 acting on pin 11 is compensated for by the reaction 63 of pin 4, and the system is balanced.
  • pin 11 engages with one of the faces (66) of the prism formed by pin 4, the composition of forces 12 and 63 giving rise to a resultant 64 which aids the rotation of the said thrust-block with increasing force as component 12 increases.
  • a shape appropriate to the desired increase of the resulting force such as 64, Fig. 18
  • a shape appropriate to the desired increase of the resulting force such as 64, Fig. 18
  • the various possible embodiments of the safety thrust-block according to the invention are not limited to those described above, that in particular one may place one or several height adjusting plates between the supporting plate (1, 34, 42, or 50) and the ski 2, these plates being fixed to said ski 2 by means of screws 3 which traverse them, in such manner that (see above figures) the lips 8 of the thrust-block body engage exactly above the sole of the boot.
