Definitions

  • Salomon SAFETY SKI BINDING My present invention relates to a safety ski binding of the type wherein a boot-engaging clamp is laterally movable, in response to severe stresses, to release the boot of a skier.
  • Ski bindings are also known in which a heel or toe clamp may swing upwardly to let the engaged boot escape in the event of a fall.
  • the general object of my present invention is to provide a simple and dependable construction combining these two types of escapement.
  • a more particular object is to provide means in a ski binding of this sort for enabling substantially unimpeded lateral motion of the clamp on its supporting base, with which it is normally aligned, once the clamp has been swung outwardly in response to abnormal stresses, thereby promptly freeing the foot of a falling skier.
  • the abutment or abutments are so arranged that the clamp becomes disengaged therefrom upon swinging upwardly against the biasing force.
  • the clamp (or some other ele ment coupled therewith for joint rotation about a vertical axis) may have one or more independent formations normally engaging a transverse edge of the baseplate, the lifting of the clamp off the baseplate disengaging these projections for free rotation.
  • FIG. I is a longitudinal sectional view of a ski binding according to my invention.
  • FIG. 2 is a top plan view of the binding shown in FIG. 1;
  • FIGS. 3 and 4 are views similar to FIG. 1, showing respective modifications
  • FIG. 5 is a top plan view, with parts broken away, of another embodiment
  • FIG. 6 is a side-elevational view of the embodiment of FIG. 5;
  • FIG. 7 is a top plan view of the same embodiment shown in a Iaterallyswung-out position.
  • FIG. 8- is a top plan view illustrating a modification of the embodiment of FIGS. 57;
  • FIG. 9. is a view similar to FIG. 5, illustrating another modification
  • FIG. I0 is a longitudinal sectional view taken on the line X-X of FIG. 9;
  • FIG. ll is a side-elevational view, similar to FIG. 6, of the ski binding shown in FIGS. 9 and 10.
  • FIGS. 1 and 2 I have shown a boot I resting on a ski runner 2 to which a base plate 16 is secured by several screws 20.
  • the post 13 has a flat face 17 engaged by a plunger 18 which is slidablc within housing member 6, in the longitudinal direction of the runner 2, under the pressure of a coil spring 19 whose stress can be adjusted by a knurled screw cap 22.
  • Post 9 Rotatably journaled in an end of member 6 proximal to the boot I, with the aid of another vertical post 9, is a lever 8 received in a horizontal slot of that end.
  • Post 9 is hollow and accommodates a compression spring 11 bearing upon another plunger 12 which acts upon the beveled underside of a rearward extension 3 of a clamp 3 pivotally secured to lever 8 by means of a horizontal pin 7.
  • Clamp 3 has a boot-engaging overhang 3 inches normally bearing from above upon the sole of the boot I at either the heel or the toe thereof; pin 7 thus defines a horizontal axis about which the clamp 3 may swing upwardly, against the biasing force of spring 11, to release the boot.
  • any swinging of the clamp 3 about. its vertical pivotal axis, defined by post 9, is normally restrained by a pair of depending projections 21, 21' of the clamp which straddle the lever 8 and engage a transverse edge 16' (FIG. 2) of baseplate 16.
  • the clamp 3 and its supporting link 8 will not be able to pivot sideways, about the axis of post 9, to any significant extent.
  • the entire assembly 6, 8, 3 may pivot on a larger radius about the fulcrum 13 as soon as the force of spring 19 is overcome so that the detent l8 releases the assembly from its indexed position.
  • FIG. 3 shows a generally similar binding wherein, however, a clamp 27 is mounted on an extension 29 for relative pivotal motion about a veritcal axis defined by a pin 28, the assembly 27, 29 being jointly swingable about a horizontal pin 30 secured to an extremity of a supporting member 26 comparable to member 6 of FIGS. 1 and 2.
  • Member 26 again forms a housing for a compression spring 33 whose stress may be adjusted by a threaded plug 37 and which, through the intermediary of a washer 38, bears upon a detent in the form of a ball 32 serving to index the member 26 in its normal position by engaging in a recess 36 of a post 31.
  • the latter is here hollow and accommodates a spring 111 driving a plunger 112 outwardly against a spur 29' of link 29, thereby urging the overhanging edge 27' of clamp 27 into contact with the sole of the boot.
  • FIG. 4 shows a base 43 on which a rocker arm 41 is mounted with the aid ofa pin 42 for swinging about a horizontal axis, such swinging being resisted by a biasing spring 46 bearing upon a spur 41' of arm 41 into which a screw 47 is adjustably threaded to vary the pressure of that spring.
  • a clamp 48 is pivotable about a vertical pin 49 held in a projecting end of a supporting lever 50 whose other end is received in a horizontal slot of arm 41 for pivotal movement about the axis of a post 52.
  • a transverse pin 51 immobilizes the clamp support 50 with reference to post 52, the latter having an indentation 52' engaged by a spherical detent 56 under pressure of a spring 53 lodged in arm 41.
  • a pair of projections 221 depending from clamp 48 normally rest against an edge of the base 43 to restrain its lateral mobility with reference to that base about a vertical axis (i.e.
  • FIGS. -7 l have illustrated another embodiment wherein a clamp 67 is part ofa generally parallelogrammatic linkage including a pair of lateral anns 63, 66 articulated at 62 to opposite ends of a horizontal stud 61 which is rotatably lodged in a base 60 so as to form a hinge joint therewith.
  • This base forms two parallel cylinders for a pair of pistons 68, 69 which are urged toward stud 61 by respective coil springs 70 whose pressure may be adjusted by respective screws 74, 74'.
  • Piston 68 bears upon a flat end 71 ofclamp-supporting arm 63 so as to restrain, any lateral displacement of clamp 67, e.g. as illustrated in FIG. 7.
  • Piston 69 similarly coacts with a flattened face 72 of stud 61 to resist rotation of that stu'd about its horizontal axis, as illustrated in FIG. 6.
  • the biasing forces opposing these two escapement motions may thus be independently adjusted with the aid ofscrews 74 and 74.
  • end face 71 of arm 63 disengages itself to a greater or less extent from piston 68 so that the clamp 67 becomes readily movable to one sideor the other for completely releasing the boot 1.
  • FIG. 8 shows a generally similar ski binding whose base 80 carries two pistons 90, 90' corresponding to pistons 69, 68 of FlGS. 57.
  • Piston 90 acts upon a flattened end face 91 of a lateral arm 81 of a generally parallelogrammatic linkage which, in addition to a horizontal stud 83 joumaled on base 80, also includes a second lateral arm 82 and a crossbar 88 articulated to these arms at pivots 89.
  • the free ends of arms 81 and 82 carry a pair of clamp jaws 86, 87 bearing upon the boot 1. These clamp jaws are again upwardly and laterally movable in response to severe stresses in the manner described with reference to the preceding embodiments.
  • FIGS. 9-1l l have shown a ski binding having the same generally parallelogrammatic clamp-supporting linkage as the device of FIGS. 5-7, this linkage being mounted on a base 100 which forms a housing for a single-biasing spring 103 anchored to a transverse bar 104 by a stem 108 and a bolt 110.
  • the head of this bolt rests against a bifurcate extremity 113 of stem 108 and is held in position by a nut 115 enabling its lateral shifting within a curved slot 101.
  • the flattened extremities 105, 106 of bar 104 bear upon the pistons 68 and 69 under the urging of biasing spring 103 whose pressure may be varied with the aid ofa screw cap 102.
  • the pin 110 may be displaced in slot 101 to one side or the other so as to shift the point of attack of the spring within a zone generally midway between the two pistons.
  • an upward swing of the clamp 67 to release the boot 1 substantially decouples the parallelogrammatic linkage 63, 66, 67 from the abutting face of piston 68 so that a virtually unrestrained sideways motion of the clamp becomes possible.
  • a ski binding comprising a base adapted to be fixed to a runner; a boot-engaging clamp; support means mounting said clamp on said base with freedom of upward swinging about a horizontal axis and lateral motion transversely to the runner to release an engaged boot; biasing means on said base resisting said upward swinging; and abutment means on said base independent of said biasing means for restraining said lateral motion, said clamp being mounted for disengagement from said abutment means upon upward swinging against the force of said biasing means.
  • said support means comprises a member pivotally secured to said base for rotation about a first vertical axis relatively remote from a boot-engaging portion of said clamp, said clamp being mounted on said member for rotation relative thereto about a second vertical axis relatively close to said boot-engaging portion; further comprising detent means yieldably indexing said member in an operative position aligned with the boot on said base, said abutment means substantially restraining rotation of said clamp about said second vertical axis only.
