Abstract
Abstract A binding to releasably attach a boot to a ski which facilitates release of the boot with the heel of the boot fastened to the ski or with the heel of the boot free to rotate above the ski about the toe of the boot above the ski. The binding includes a pin assembly mountable to the ski and a socket assembly which rotatably and releasably engages the pin assembly and which receives and carries the toe of the boot. In operation, the boot is biased into the socket assembly and when a force is applied to the boot overcoming the bias, the boot is released from the ski to prevent injury to the skier.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A ski binding comprising: a first plate member attachable to a ski; a cylinder carried upon said first plate member of first diameter along a center portion and second smaller diameter adjacent its end portions; a second plate member for carrying a boot; a pair of cylinder engaging portions carried upon said second plate into which said end portions may be transversely, pivotally and removably inserted, whereby when said boot is carried upon said second plate the toe of the boot is located adjacent said cylinder engaging portions; and means for biasing said end portions into inserted position with said cylinder engaging portions, whereby the boot is pivotally movable about the axis of said cylinder, and is released from said cylinder upon application of a force overcoming the bias of said biasing means.
Claim 2
Dependent Claim
133 words
A ski binding comprising: a first plate member attachable to a ski; a cylinder carried upon said first plate member of first diameter along a center portion and second smaller diameter adjacent its end portions; a second plate member for carrying a boot; a pair of cylinder engaging portions carried upon said second plate into which said end portions may be transversely, pivotally and removably inserted, whereby when said boot is carried upon said second plate the toe of the boot is located adjacent said cylinder engaging portions; and means for biasing said end portions into inserted position with said cylinder engaging portions, whereby the boot is pivotally movable about the axis of said cylinder, and is released from said cylinder upon application of a force overcoming the bias of said biasing means.
Claim 3
Dependent Claim
18 words
The ski binding of claim 1 wherein said cylinder includes a taper between its first and second diameters.
Claim 4
Dependent Claim
34 words
The ski binding of claim 2 wherein said two cylinder engaging portions are each of truncated, frusto-conical shape, being hollow therewithin to receive the taper between said first and second diameters of said cylinder.
Claim 5
Dependent Claim
130 words
A releasable ski binding comprising: a. a first plate member mountable contiguously with the upper surface of a ski adjacent the ordinary location of the toe of a ski boot carried thereupon; b. a cylinder carried upon said first plate member and extending transversely of the ski; c. a second plate member adapted to grasp the toe of the ski boot and movable therewith; d. means integral with said second plate member for forming at least one forwardly opening socket axially aligned with said cylinder and adapted to receive and rotatably engage said cylinder therewithin when the toe of the ski boot is urged forwardly on the ski; e. so that said second plate member may pivot with said ski boot through any angle about the axis of the cylinder.
Claim 6
Dependent Claim
130 words
A releasable ski binding comprising: a. a first plate member mountable contiguously with the upper surface of a ski adjacent the ordinary location of the toe of a ski boot carried thereupon; b. a cylinder carried upon said first plate member and extending transversely of the ski; c. a second plate member adapted to grasp the toe of the ski boot and movable therewith; d. means integral with said second plate member for forming at least one forwardly opening socket axially aligned with said cylinder and adapted to receive and rotatably engage said cylinder therewithin when the toe of the ski boot is urged forwardly on the ski; e. so that said second plate member may pivot with said ski boot through any angle about the axis of the cylinder.
Claim 7
Dependent Claim
50 words
The device claimed in claim 4 wherein said cylinder is provided with a pair of reduced diameter axially extending pins at the respective extremities thereof and wherein said at lEast one forwardly opening socket consists of two of said sockets adapted to engage said pair of axially extending pins respectively.
Claim 8
Dependent Claim
17 words
The device of claim 5 wherein the extremities of said cylinder are tapered outwardly toward said pins.
Claim 9
Dependent Claim
24 words
The device of claim 6 wherein said two sockets are each of frusto-conical shape adapted to conform to and bear against said tapered extremities.
Claim 10
Dependent Claim
35 words
The device of claim 4 wherein said cylinder is provided with at least one reduced diameter portion intermediate its extremities, and wherein said cylinder is tapered inwardly toward said at least one reduced diameter portion.
Claim 11
Dependent Claim
34 words
The device of claim 8 wherein said at least one socket consists of a pair of sockets of frusto-conical shape adapted to conform to and bear against the inwardly tapered portions of said cylinder.
