Abstract

Abstract An adjustable connection between a ski and its binding, comprising an elevated platform that is attached to the ski at two longitudinally spaced points by supports that allow the ski to flex between the supports. Mounted on top of the elevated platform is a boot plate, to which the ski binding is attached. The boot plate is attached to the platform by screw connections that allow for rotation of the boot plate about a vertical axis, or for translation in the fore-and-aft or lateral directions. The supports, in one form of the invention, are individually adjustable in length so that the platform can be tilted laterally with respect to the top surface of the ski, or tilted longitudinally, or raised and lowered while maintaining parallelism with respect to the ski. Thus, the invention allows for rotational adjustment about any one or all 3 mutually perpendicular axes, as well as translational adjustment in all 3 planes, all without removing the ski bindings from the platform, or the platform from the ski. In another form of the invention, the canting adjustment (i.e., lateral tilting) is accomplished with wedges and translational adjustments are limited to fore-and-aft and to lateral movement. The boot plate is shiftable longitudinally with respect to the platform, and also laterally; and is rotatable about a vertical axis.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 147 words
An adjustable connection for use between ski bindings and a ski, comprising: an elevated platform adapted to be mounted on the ski; a boot plate to which the ski bindings are attached, said boot plate being mounted on top of said platform and being angularly adjustable with respect thereto in a substantially horizontal plane to compensate for toe-in or toe-out angularity of the foot and thereby position the skis parallel to one another despite the angularity of the skier's feet; said boot plate being also adjustable longitudinally with respect to the length of the ski by sliding the boot plate forwardly or rearwardly on said platform so as to position the skier's weight at the optimum location along the length of the skis for the type of skiing being done or for conditions of the ski slope; and means for securing said boot plate in adjusted position.
Claim 2
Dependent Claim 147 words
An adjustable connection for use between ski bindings and a ski, comprising: an elevated platform adapted to be mounted on the ski; a boot plate to which the ski bindings are attached, said boot plate being mounted on top of said platform and being angularly adjustable with respect thereto in a substantially horizontal plane to compensate for toe-in or toe-out angularity of the foot and thereby position the skis parallel to one another despite the angularity of the skier's feet; said boot plate being also adjustable longitudinally with respect to the length of the ski by sliding the boot plate forwardly or rearwardly on said platform so as to position the skier's weight at the optimum location along the length of the skis for the type of skiing being done or for conditions of the ski slope; and means for securing said boot plate in adjusted position.
Claim 3
Dependent Claim 27 words
An adjustable connection as set forth in claim 1, wherein means is provided for adjusting the transverse inclination of the boot plate with respect to the ski.
Claim 4
Dependent Claim 97 words
An adjustable connection as set forth in claim 1, wherein said elevated platform is connected at its front end to said ski by a pair of laterally spaced legs that are adjustable in length, and at its rear end by a second pair of laterally spaced legs that are adjustable in length, so as to allow for adjusting the transverse inclination of the boot plate with respect to the ski by lengthening or shortening the legs on one side of the boot plate to compensate for canting of the skis caused by bow legs or knock knees.
Claim 5
Dependent Claim 33 words
An adjustable connection as in claim 1, wherein said boot plate is rotationally adjustable with respect to the ski about 3 mutually perpendicular axes, and is translationally adjustable in 3 mutually perpendicular planes.
Claim 6
Dependent Claim 50 words
An adjustable connection as in claim 1, wherein said boot plate is rotationally adjustable with respect to said elevated platform about a perpendicular axis, and is translationally adjustable with respect to the platform in the direction parallel to the lengthwise axis of the ski and also laterally with respect thereto.
Claim 7
Dependent Claim 69 words
An adjustable connection as in claim 5, wherein said boot plate is attached to said platform by two longitudinally spaced screws which pass through elongated slots in the boot plate and in the platform, the slots in said boot plate extending in one direction with respect to the lengthwise axis of the ski, and the slots in said platform extending generally perpendicular to the slots in the boot plate.
