Abstract
Abstract Support devices for the shanks of skier's legs wherein levers on opposite sides of and parallel to the shank are pivoted about an axis at ankle height and secured to the shank just beneath the knee by a flexible strap. Two rods are pivoted to the lever arrangement on each side. In the case of a single lever the rods are pivoted above and below the lever axis. For parallel levers one rod is pivoted above the axis of one lever and the other rod below the axis of the other lever. In each case the rods pass through a resilient compressible block. When the shank swings forward a stop on one rod compresses the block, while the other rod moves freely in the opposite direction. When the shank swings backward the roles of the rods are reversed.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
156 words
A support device for the shank of a skier's leg comprising a frame adapted to be fixed with respect to a ski and to extend on opposite sides of ski boot, two lever arrangements respectively separately and independently pivoted to opposite sides of said frame in positions to extend along opposite sides of the skier's shank approximately parallel thereto, said lever arrangements being separately pivoted about separate pivot positions approximately at the height of the skier's ankle for said lever arrangements to swing forwards and backwards with respect to the length of the ski, each lever arrangement comprising at least one lever, means for securing said lever arrangements to the skier's shank in the calf region thereof, spring means mounted on said frame and mechanical means interposed between said lever arrangements and said spring means whereby said spring means oppose swinging movement of said lever arrangements both forwards and backwards with respect to a zero position.
Claim 2
Dependent Claim
156 words
A support device for the shank of a skier's leg comprising a frame adapted to be fixed with respect to a ski and to extend on opposite sides of ski boot, two lever arrangements respectively separately and independently pivoted to opposite sides of said frame in positions to extend along opposite sides of the skier's shank approximately parallel thereto, said lever arrangements being separately pivoted about separate pivot positions approximately at the height of the skier's ankle for said lever arrangements to swing forwards and backwards with respect to the length of the ski, each lever arrangement comprising at least one lever, means for securing said lever arrangements to the skier's shank in the calf region thereof, spring means mounted on said frame and mechanical means interposed between said lever arrangements and said spring means whereby said spring means oppose swinging movement of said lever arrangements both forwards and backwards with respect to a zero position.
Claim 3
Dependent Claim
29 words
A support device according to claim 1, in which said means for securing said lever arrangements to the skier's shank comprise a flexible strap for surrounding the skier's shank.
Claim 4
Dependent Claim
24 words
A support device according to claim 1, in which said spring means comprise two separate spring devices associated respectively with said two lever arrangements.
Claim 5
Dependent Claim
53 words
A support device according to claim 1, in which said frame comprises a retaining plate adapted to be secured to the ski forward of the ski boot by a ski binding, and a stirrup piece having a transverse portion to be pressed onto the ski beneath the heel zone of the ski boot.
Claim 6
Dependent Claim
40 words
A support device according to claim 1, in which each said lever arrangement comprises a pair of substantially parallel levers respectively pivoted about two separate axes to said frame, said axes being approximately at the height of the skier's ankle.
Claim 7
Dependent Claim
48 words
A support device according to claim 5, in which said mechanical means interposed between said lever arrangements and said spring means operate only to oppose the movement of one lever in each said pair when swinging forwards and the other lever in that pair only when swinging backwards.
Claim 8
Dependent Claim
87 words
A support device according to claim 1, in which said mechanical means interposed between said lever arrangements and said spring means comprise two pairs of force transmission elements, one pair for each lever arrangement, the force transmission elements for each lever arrangement being so connected thereto that said spring means only oppose the movement of the lever arrangement in one direction from said zero position through one of said pair of force transmission elements and in the other direction through the other of said force transmission elements.
Claim 9
Dependent Claim
53 words
A support device according to claim 7, in which each said lever arrangement comprises one lever pivoted about an axis on said frame and in which said force transmission elements in each pair thereof are pull rods pivoted to the associated lever at points respectively above and below said axis on said frame.
Claim 10
Dependent Claim
27 words
A support device according to claim 8, in which said spring means consist of a body of resilient material arranged to be compressed by said pull rods.
Claim 11
Dependent Claim
39 words
A support device according to claim 8, in which said pull rods in each said pair thereof are pivoted to the associated lever at points that are respectively at different distances above and below said axis on said frame.
Claim 12
Dependent Claim
44 words
A support device according to claim 8, in which said pull rods in each pair thereof are pivoted to the associated lever respectively at an upper point and a lower point which is at a smaller distance from said axis than said upper points.
Claim 13
Dependent Claim
57 words
A support device according to claim 8, comprising pivotal connecting means interposed between each said lever and at least one of said pull rods in the pair thereof associated with the lever whereby the distance between said axis of the lever and the pivoted connection between said one of said rods and said lever can be adjusted.
Claim 14
Dependent Claim
93 words
A support device according to claim 7, in which each said lever arrangement comprises two substantially parallel levers respectively pivoted about two axes on said frame and in which said force transmission elements in each pair thereof are pull rods pivoted to the levers in the associated pair thereof with one said rod pivoted to one lever in said pair of levers above the pivot of that lever and the other rod in said pair of rods pivoted to the other lever in said pair of levers below the pivot of that lever.
Claim 15
Dependent Claim
20 words
A support device according to claim 7, in which said force transmission elements are arranged to act only in tension.
Claim 16
Dependent Claim
73 words
A support device according to claim 7, in which said spring means comprise abutment means fixed on said frame and compression spring devices bearing on said abutment means, and in which said force transmission elements comprise rods extending from said lever arrangements and passing through apertures in said compression spring devices and stop means adjustably mounted on said rods to bear on said compression spring means at locations opposed to said abutment means.
Claim 17
Dependent Claim
20 words
A support device according to claim 7, in which said force transmission elements are detachably connected to said lever arrangements.
Claim 18
Dependent Claim
27 words
A support device according to claim 7, in which said spring means are located so as to lie approximately in the instep zone of the ski boot.
Claim 19
Dependent Claim
15 words
A support device to claim 1, in which each said lever is adjustable in length.
Claim 20
Dependent Claim
