Abstract
Abstract A ski binding comprises a pair of pivoted jaws, a stop member forming an abutment for extremities of the jaws to limit movement of the jaws together to a boot-holding position, and a spring urging said extremities against a stop member. The spring is disposed along a screw mounted for rotation but against longitudinal movement relative to the stop member, and an end of the spring bears against a non-rotatable nut on an end of the screw. The stop member is screwably mounted on a frame of the binding to enable adjustment of the longitudinal position of the stop member, and hence the separation of the jaws in the bootholding position, independently of adjustment of the force of the spring by the screw.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
204 words
Safety ski binding comprising a frame, a pair of jaw members pivotally mounted on the frame for movement of boot-engaging parts of the members together and apart, a stop member constituting an abutment for extremities of the jaw members which limits movement of the boot-engaging parts together, elastic means for urging said extremities of the jaw members towards the stop member to tend to hold said boot-engaging parts together in a boot-holding position, a screw mounted for rotation but against longitudinal movement relative to the stop member, the elastic means being disposed along The screw, a nut threadably engaged on the screw and constituting a support against which the elastic means bears, means for fixing the nut against rotation but allowing movement thereof along the longitudinal direction of the screw to enable adjustment of the force of the elastic means by rotation of the screw, and adjustment means for screwably mounting the stop member on the frame to enable adjustment of the position of the stop member in the longitudinal direction of the screw and thereby adjustment of the separation of said bootengaging parts in said boot-holding position independently of any adjustment of the force of the elastic means by the screw and nut.

Safety ski binding comprising a frame, a pair of jaw members pivotally mounted on the frame for movement of boot-engaging parts of the members together and apart, a stop member constituting an abutment for extremities of the jaw members which limits movement of the boot-engaging parts together, elastic means for urging said extremities of the jaw members towards the stop member to tend to hold said boot-engaging parts together in a boot-holding position, a screw mounted for rotation but against longitudinal movement relative to the stop member, the elastic means being disposed along The screw, a nut threadably engaged on the screw and constituting a support against which the elastic means bears, means for fixing the nut against rotation but allowing movement thereof along the longitudinal direction of the screw to enable adjustment of the force of the elastic means by rotation of the screw, and adjustment means for screwably mounting the stop member on the frame to enable adjustment of the position of the stop member in the longitudinal direction of the screw and thereby adjustment of the separation of said bootengaging parts in said boot-holding position independently of any adjustment of the force of the elastic means by the screw and nut.
Claim 3
Dependent Claim
20 words
Binding according to claim 1 wherein said adjustment means comprises a sleeve having threaded outer surface concentric with said screw.
Claim 4
Dependent Claim
194 words
A ski binding device comprising a mounting member; two jaw levers pivotally mounted on said member about vertical axes and each having jaw means on one end for rearwardly laterally pressing against a boot sole with an elastic force which can be overcome to free the boot when a lateral force on the boot reaches a given value, each lever also having an other end; elastic means for longitudinally engaging the other ends of said levers with pressure to cause the jaw means to engage the boot sole; elongate rotatably actuatable first adjustment means for adjusting said given value, said elongate means having a first end which bears against said mounting member, and having a second threaded end; a nut threaded on said second threaded end and held against rotation to constitute a stop for a free end of the elastic means and thereby to adjust the pressure of the elastic means; and a second adjustment means mounted on said mounting member in a longitudinally adjustable position for laterally adjusting the positions of said jaw means to fit boot soles of different size, independently of said adjusting of the pressure of the elastic means.
Claim 5
Dependent Claim
194 words
A ski binding device comprising a mounting member; two jaw levers pivotally mounted on said member about vertical axes and each having jaw means on one end for rearwardly laterally pressing against a boot sole with an elastic force which can be overcome to free the boot when a lateral force on the boot reaches a given value, each lever also having an other end; elastic means for longitudinally engaging the other ends of said levers with pressure to cause the jaw means to engage the boot sole; elongate rotatably actuatable first adjustment means for adjusting said given value, said elongate means having a first end which bears against said mounting member, and having a second threaded end; a nut threaded on said second threaded end and held against rotation to constitute a stop for a free end of the elastic means and thereby to adjust the pressure of the elastic means; and a second adjustment means mounted on said mounting member in a longitudinally adjustable position for laterally adjusting the positions of said jaw means to fit boot soles of different size, independently of said adjusting of the pressure of the elastic means.
Claim 6
Dependent Claim
59 words
Binding device according to claim 3 including plate means for transmitting the pressure of the elastic means to said other ends of the jaw levers, said plate means having a flat central face and two outer faces adjacent to opposite edges of the central face and inclined to the central face in the general direction of the elastic means.
Claim 7
Dependent Claim
205 words
A ski binding device comprising two jaw levers pivotally mounted on a ski about vertical axes and each having jaw means on one end for rearwardly laterally pressing against a boot sole with an elastic force which can be overcome to free the boot when a lateral force on the boot reaches a given value, each lever also having an other end; a stationary member on the ski; elastic means for longitudinally engaging, with a first end thereof, the other ends of said levers with pressure to cause the jaw means to engage the boot sole; elongate rotatably actuatable first adjustment means, for adjusting said given value, said elongate means having a first end which bears against the stationary member and having a second, threaded end and a nut threaded thereon and held against rotation to constitute a stop for a second end of the elastic means; and a second adjustment means comprising a sleeve mounted on said stationary member in a longitudinally adjustable position and having a flange at a first end thereof constituting a stop for said other ends of said jaw levers, said sleeve having a second end, against which said first end of said first adjustment means bears with low friction.
Claim 8
Dependent Claim
205 words
A ski binding device comprising two jaw levers pivotally mounted on a ski about vertical axes and each having jaw means on one end for rearwardly laterally pressing against a boot sole with an elastic force which can be overcome to free the boot when a lateral force on the boot reaches a given value, each lever also having an other end; a stationary member on the ski; elastic means for longitudinally engaging, with a first end thereof, the other ends of said levers with pressure to cause the jaw means to engage the boot sole; elongate rotatably actuatable first adjustment means, for adjusting said given value, said elongate means having a first end which bears against the stationary member and having a second, threaded end and a nut threaded thereon and held against rotation to constitute a stop for a second end of the elastic means; and a second adjustment means comprising a sleeve mounted on said stationary member in a longitudinally adjustable position and having a flange at a first end thereof constituting a stop for said other ends of said jaw levers, said sleeve having a second end, against which said first end of said first adjustment means bears with low friction.
