Abstract
Abstract The present invention relates to a safety binding of a boot on a ski comprising two lateral clamps (4) movably mounted under the action of an elastic member (28) parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. Each clamp (4) is connected to one end of a longitudinally slidable strip (45) by means of articulatedly interconnected rods. The other end of the strip coacts with a crank (29-30) subjected to the action of the resilient member, whereby this crank has two stable positions corresponding to the respective open and closed positions of the clamps.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
Safety binding of a boot on a ski comprising two lateral clamps movably mounted under the influence of a resilient member parallel to the plane of the ski between a closed position in which these clamps coact with the boot sole and an open position, characterized by the fact that each clamp is carried by an arm pivotally mounted on the ski and is connected to one end of a longitudinally slidable strip by means of articulatedly interconnected rods, and by the fact that the other end of the strip coacts with a crank subjected to the action of the resilient member, whereby this crank has two stable positions corresponding to the respectively open and closed positions of the clamp.
Claim 2
Dependent Claim
120 words
Safety binding of a boot on a ski comprising two lateral clamps movably mounted under the influence of a resilient member parallel to the plane of the ski between a closed position in which these clamps coact with the boot sole and an open position, characterized by the fact that each clamp is carried by an arm pivotally mounted on the ski and is connected to one end of a longitudinally slidable strip by means of articulatedly interconnected rods, and by the fact that the other end of the strip coacts with a crank subjected to the action of the resilient member, whereby this crank has two stable positions corresponding to the respectively open and closed positions of the clamp.
Claim 3
Dependent Claim
17 words
Binding according to claim 1, characterized by the fact that the crank is actuated by a lever.
Claim 4
Dependent Claim
47 words
Binding according to claim 1, characterized by the fact that the crank comprises an elbowed member whose one end bears against the end of the strip and whose other end is articulated on a rod connected to a piston subjected to the action of the resilient member.
Claim 5
Dependent Claim
83 words
Binding according to claim 2, characterized by the fact that the crank comprises a casing in two parts containing the elastic member and slidably mounted one in the other, by the fact that one of the parts of the casing is pivotally mounted on a fixed transverse axle and that the other part is pivotally mounted on a transverse axle secured to the lever, this lever being itself pivotally mounted on a fixed transverse axle and bearing against the end of the strip.
Claim 6
Dependent Claim
76 words
Binding according to claim 1, characterized by the fact that the end of the strip opposite that coacting with the crank is connected to each lateral clamp by means of two straight rods, the first rod being articulated to the strip and to the second rod, and the latter being articulated to the clamp, and by the fact that the second rod is pivotally mounted by its outer edge about a roller secured to the ski.
Claim 7
Dependent Claim
100 words
Binding according to claim 1, characterized by the fact that the end of the strip opposite that coacting with the crank is connected to each lateral clamp by means of straight rods articulated on the end of the strip and an elbowed rod articulated on the one hand to the straight rod and on the other hand to the clamp, and by the fact that the elbowed rod is pivotally mounted by its elbowed portion about a vertical axle secured to the ski and having an elongated opening at its end coacting with a vertical axle secured to the clamp.
Claim 8
Dependent Claim
32 words
Binding according to claim 1, characterized by the fact that it comprises an automatic closure device coacting with the strip or the crank and adapted to be actuated by the ski boot.
Claim 9
Dependent Claim
43 words
Binding according to claim 7, characterized by the fact that the closure device is a lever pivotally mounted on a transverse axle secured to the ski, this lever having a portion in contact with the strip in the open position of the clamps.
Claim 10
Dependent Claim
38 words
Binding according to claim 7 for a ski having a braking device, characterized by the fact that the closure device is constituted by a movable member of the braking device or by a member actuated by this device.
Claim 11
Dependent Claim
48 words
Binding according to claim 9, characterized by the fact that the movable member of the braking device is a cylinder fixed for rotation to a lateral arm of the device, this cylinder having at least one lug coacting with the strip in the open position of the clamps.
Claim 12
Dependent Claim
20 words
Binding according to claim 1, characterized by the fact that the elastic member is disposed rearwardly of the lateral clamp.
Claim 13
Dependent Claim
24 words
Binding according to claim 11, characterized by the fact that a longitudinally adjustable stop is disposed on the ski forward of the lateral clamps.
Claim 14
Dependent Claim
20 words
Binding according to claim 1, characterized by the fact that the resilient member is disposed forwardly of the lateral clamps.
