  • the present invention relates to safety ski binding devices.
  • ski bindings comprise a boot sole gripping member which does not ex actly follow movement of the end of the boot in the case of frontwards, rearwards or lateral falls. It has al ready been proposed to provide ski bindings comprising a boot sole gripping member which more or less exactly follows movement of the corresponding end of the boot, but in most of these types the boot sole gripping member has two fixed supports cooperating with guide means, a return device urging the boot sole gripping member into its stable rest position.
  • Such constructions proposed to date have the drawback of being relatively complex and consequently costly to manufacture.
  • the safety ski binding device accordingly comprises a boot sole gripping member borne by two supporting members movable relative to one another when said gripping member is moved, and stop means for limiting movement of said support members.
  • FIG. I is a schematic plan view of a first embodiment of device according to the invention.
  • FIG. 2 is a view similar to FIG. 1, showing different positions of the boot sole gripping member.
  • FIG. 3 is also a view similar to FIG. 1 showing yet another position of the boot sole gripping member.
  • FIG. 4 is a schematic plan view of another embodiment.
  • FIG. 5 is a view similar to FIG. 1 for a slightly modified embodiment.
  • FIG. 6 is a cross-section taken along line 6-6 of FIG. B, showing in fully detail the construction of another embodiment.
  • FIG. 7 is a view similar to FIG. 6, but in another position.
  • FIGS. 8 and 9 are cross-sections respectively taken along lines 8-8 and 9-9 of FIG. 6.
  • FIG. 10 is a view similar to FIG. 8, but in another position.
  • a boot sole gripping member A is guided on two supports B and C held apart by a compression spring D, the longitudinal axis of a ski to which the device is secured being shown by line X-X.
  • FIG. 2 illustrates operation of the device when the member A is moved towards the right, as indicated by arrow E.
  • the support B is moved relative to the support C, which bears against a stop member and thus remains fixed, and the spring D is compressed.
  • the various sequential positions of the member A are shown in dashed lines, and it can be seen that when the support B reaches B and the mid-point of the member A has reached the temporarily fixed support C, the member A pivots to a boot-releasing position.
  • the member A and a boot gripped thereby are elastically returned to the initial position by the action of the spring D.
  • the boot sole gripping member A is guided on two supports B and C each carried on the end of a lever F, G respectively pivotally mounted at H and I.
  • the spring D holds the levers F and G applied against stops L and M and the levers are therefore only able to move inwards. Operation is the same as for the embodiment of FIGS. 1 to 3.
  • Adjustment of the release effort takes place by longitudinal displacement of the spring D, as shown in broken lines.
  • the stops L and M can be cam-shaped, and the levers F and G may be pivotally mounted about a transversal axis at their ends H and I to allow release of the device in the case of lifting the member A, that is, in the case of a toe-stop binding, as a result of a rearward fall. Adjustment of this release effort thus takes place by longitudinal displacement of the stops L and M.
  • the supports B and C could be rollers mounted on the ends of the levers F and G.
  • levers F and G could slide along one or several grooves provided in the member A.
  • FIG. 5 shows how the supports B and C together with the spring D are mounted in an envelope-like casing N preventing escape of the supports B and C to the exterior.
  • An opening enables the passage of the protruding nose-portion O or P of the member A, which portions drive one or the other of the supports B or C according to the direction of movement of the member A.
  • FIGS. 6 to 10 The device shown in FIGS. 6 to 10 is a safety ski binding toe piece operating according to the same principle as the schematic embodiments described above. With several minor modifications, notably in the shape of the boot heel gripping member, this device could also be used as a heel binding.
  • the device comprises two levers l, 2 each pivotally mounted at one end to a hinge block 3 about shafts 1, 2' normally perpendicular to the ski surface (not shown), this block 3 being pivotally mounted about a transversal shaft 5 mounted in lugs 4 made integrally witha base plate 4 adapted to be fixed onto a ski.
  • the other end of each lever 1, 2 has an outwardly facing hook shaped part 6, 7 respectively cooperating with hooking members8, 9 fixed on a boot sole gripping member 10.
  • Each hooking member 8, 9 is formed by a pin with a sleeve or roller 8', 9' freely rotatably mounted thereon.
  • the hook shaped parts 6, 7 of the levers l and 2 each have a ramp surface 6, 7' respectively for guiding the corresponding roller 8', 9'.
  • the levers 1, 2 each respectively comprise an inwardly protruding part ll, 12 on which is mounted a roller 13, 14 respectively contacting ramp surfaces 15, 16 (FIG. 9) on an upwardly protruding part 17 of the base plate 4.
  • Each ramp 15, 16 has at its base a housing 15', 16' respectively forming a cam for positionally retaining the corresponding roller 13, 14.
  • a compression spring 18 is disposed between the levers l and 2 in a manner to elastically urge the hook shaped parts 6 and 7 respectively into engagement with the rollers 8,9' of a support block part of the member 10.
  • the compression of the spring 18 can be adjusted from the exterior by means of a screw 19.
  • the boot sole gripping member has a rear part 20 which comes directly into contact with the boot sole and is partially shown in plan in FIG. 6.
  • This part 20 is slidably mounted on two pins 21 fixed on the member 10 and a screw 22 enables adjustment of the height of part 20 according to the thickness of the boot sole.
  • the described device operates as follows In the normal use position, the levers l and 2 are in engagement with the hooking members 8 and 9 of the support block 10, as shown in FIG. 6.
  • the boot Under the effect of a torsional effort over and above a given value moves laterally, for example into the position shown in FIG. 7.
  • the roller 9' after rolling over the ramp surface 7 of the hook shaped part 7, comes to bear on the outer side surface of the lever 2 whilst the lever 1 has pivoted inwardly against the force of the spring 18 which bears against the lever 2.
  • the member 10 with its part 20 has pivoted to release the boot which can thus be freed.
  • the base plate 4 could carry rollers against each of which a ramp surface carried by the levers l and 2 would hear, these ramp surfaces moving over the rollers against the force of the spring 18 when the support block 10 is lifted up in the case of a rearward fall.
  • the ramp surfaces 15 and 16 and the rollers 13 and 14 could be replaced by magnetic means, for example a magnet whose force can be adjusted by modifying the pole-gap.
  • pivoting shafts 1', 2' at the ends of levers l, 2 could be staggered longitudinally in a manner to obtain an asymetric effect in release of the described device, which would take place more easily in one lateral direction than in the other.
  • a safety ski binding device comprising:
  • each of said levers at a first end thereof being pivotally mounted about an axis prependicular to a ski surface, and each of said levers at a second end thereof having a hook-shaped portion with a laterally outwardly facing opening;
  • ski boot sole gripping member supported by said two levers, said gripping member having mounted thereon a pair of laterally spaced hooking members; means for holding said boot gripping member in an operative boot holding position; said means including elastic means mounted to pivot said two levers outwardly around said axes at said first ends thereof to urge said outwardly facing openings of said second ends of said levers into an operative hooking member receiving position wherein each of said hooking members is received in one of said outwardly facing openings and wherein said gripping member is in a boot gripping position; and
  • each of said outwardly facing openings of said hookshaped portions of said levers having an inner surface means for guiding the corresponding hooking member out of said opening into a position in which said gripping member is in a boot releasing position when said gripping member is laterally moved as a result of the application of a lateral force above a predetermined value.
  • a safety ski binding device comprising:
  • a base plate member adapted to be attached to a ski surface
  • each of said levers at a first end thereof being pivotally mounted about an axis perpendicular to said ski surface, and each of said levers at a second end thereof having a hook-shaped portion with a laterally outwardly facing opening;
  • a boot sole gripping member supported by said two levers, said gripping member having mounted thereon a pair of laterally spaced hooking members; means for holding said boot gripping member in an operative boot holding position; said means including elastic means mounted to pivot said two levers outwardly around said axes at said first ends thereof to urge said outwardly facing openings of said second ends of said levers into an operative hooking member receiving position wherein each of said hooking members is received in one of said outwardly facing openings and wherein said gripping member is in a boot gripping position; and
  • said gripping member being laterally movable under the application thereto of lateral force by engagement of one of said hooking members with its respective hook-shaped portion, the other of said hooking members being guided by the surface of the outwardly facing opening of its respective hook-shaped portion to retain said gripping member in said boot gripping position up to a predetermined lateral movement of said gripping member, while thereafter said other hooking member is free from its said respective hook-shaped portion, said gripping member thus being pivotable about said one hooking member to a boot releasing position.
