Abstract
Abstract A device for use in snow skiing instruction to communicate to the skier that the correct ''''legs together'''' position is not being maintained. The device provides a sensory signal, audible or tactile, to the skier, on movement of the skier''s legs away from each other. A first embodiment includes an accordian pleated cylinder or bellows capable of generating a sound when it is compressed or released from a compressed state, a support plate mounted to the cylinder, and a strap connected to the support plate for mounting the entire device to the inside of one leg of the skier. A second embodiment includes an accordian pleated cylinder or bellows having a rod mounted therein for movement towards and into contact with the skier''s leg when the bellows is compressed and for movement away from and out of contact with the skier''s leg when the bellows is released from a compressed state.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
A device for snow skiing instruction to indicate to a skier that his legs have moved apart, comprising; first means for producing a sensation which the skier can detect; second means, coupled to said first means and responsive to relative leg movement, for actuating said first means upon separation of the skier''s legs; and third means for attaching said second means to one leg of a skier in a position so that one portion of said second means is moved by the other leg when the skier''s legs are moved together, said second means being operative to actuate said first means when the skier''s legs are moved apart.
Claim 2
Independent Claim
108 words
A device for snow skiing instruction to indicate to a skier that his legs have moved apart, comprising; first means for producing a sensation which the skier can detect; second means, coupled to said first means and responsive to relative leg movement, for actuating said first means upon separation of the skier''s legs; and third means for attaching said second means to one leg of a skier in a position so that one portion of said second means is moved by the other leg when the skier''s legs are moved together, said second means being operative to actuate said first means when the skier''s legs are moved apart.
Claim 3
Dependent Claim
20 words
A device according to claim 1 wherein said second means includes a compressible bellows having an aperture at one end.
Claim 4
Dependent Claim
27 words
A device according to claim 2 wherein said first means provides an audible sensation and includes a pneumatic noisemaker carried by said bellows at said one end.
Claim 5
Dependent Claim
38 words
A device according to claim 2 wherein said first means provides a tactile sensation and includes an elongated rod carried by said bellows opposite said one end for movement into and out of contact with the skier''s leg.
Claim 6
Independent Claim
109 words
A device for skiing instruction to indicate to the skier that his legs have moved apart, comprising; a support plate; a sensory signaling element capable of producing a sensation which the skier can detect; means, coupled to said sensory signaling element and to said support plate, for actuating said sensory signaling element upon separation of the skier''s legs; and means for fastening said support plate to one leg of a skier in a position so that one portion of said means for actuating is moved by the other leg when the skier''s legs are moved together, said means for actuating being operative when the skier''s legs are moved apart.
Claim 7
Independent Claim
109 words
A device for skiing instruction to indicate to the skier that his legs have moved apart, comprising; a support plate; a sensory signaling element capable of producing a sensation which the skier can detect; means, coupled to said sensory signaling element and to said support plate, for actuating said sensory signaling element upon separation of the skier''s legs; and means for fastening said support plate to one leg of a skier in a position so that one portion of said means for actuating is moved by the other leg when the skier''s legs are moved together, said means for actuating being operative when the skier''s legs are moved apart.
Claim 8
Dependent Claim
40 words
A device according to claim 5 wherein said means for actuating includes a compressible cylindrical bellows having an aperture at one end and wherein said signaling element includes an elongated rod carried by said bellows for movement through said aperture.
Claim 9
Dependent Claim
15 words
A device according to claim 5 wherein said sensory signaling element includes a pneumatic noisemaker.
Claim 10
Dependent Claim
35 words
A device according to claim 7 wherein said means for actuating includes a compressible cylindrical bellows having an aperture at one end, wherein said pneumatic noisemaker is mounted to said bellows coincident with said aperture.
Claim 11
Dependent Claim
49 words
A device according to claim 8 wherein said support plate is connected to said bellows and wherein one end of said bellows fits into an aperture located in said support plate, and said support plate has one elongated slot located at each end for receiving said means for fastening.
Claim 12
Dependent Claim
45 words
A device according to claim 5 wherein said means for fastening includes a first strap connected at one end to said support plate; a second strap connected at one end to said support plate; and means for connecting the other ends of said straps together.
