Abstract
Abstract A training device for ice skaters includes a body enclosing rectilinear frame and pairs of front and rear supp.ort legs depending from the frame. Runners are provided at the lower extremities of the support legs and at least the runners on the rear support legs are rotatable. Springs operatively connect the rotatable runners and their associated support legs such that during the forward movement of the trailing device the rotatable runners are caused to rotate against the bias of their respective springs into an orientation parallel to the direction of movement and when the training device is stationary the rotatable runners are biased by the springs towards an orientation substantially perpendicular to the longitudinal axis of the training device.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
146 words
A training device for ice skaters comprising: a rectilinear horizontally disposed frame dimensioned to enclose a skater; a pair of front support legs and a pair of rear support legs extending downwardly from the corners of said frame; a runner secured to each of said support legs, the runners on at least said pair of rear support legs being rotatably mounted thereon so as to be rotatable through a predetermined arc; and spring means operatively connecting each of the rotatable runners with their associated support legs, whereby during forward movement of the training device said rotatable runners are caused to rotate against the bias of said spring means into an orientation parallel to the direction of movement and when the training device is at rest said rotatable runners are biased by said springs towards an orientation substantially perpendicular to the longitudinal axis of the training device.
Claim 2
Dependent Claim
146 words
A training device for ice skaters comprising: a rectilinear horizontally disposed frame dimensioned to enclose a skater; a pair of front support legs and a pair of rear support legs extending downwardly from the corners of said frame; a runner secured to each of said support legs, the runners on at least said pair of rear support legs being rotatably mounted thereon so as to be rotatable through a predetermined arc; and spring means operatively connecting each of the rotatable runners with their associated support legs, whereby during forward movement of the training device said rotatable runners are caused to rotate against the bias of said spring means into an orientation parallel to the direction of movement and when the training device is at rest said rotatable runners are biased by said springs towards an orientation substantially perpendicular to the longitudinal axis of the training device.
Claim 3
Dependent Claim
37 words
A training device according to claim 1, wherein each said rotatable runner is mounted in the associated support leg so as to be rotatable about a vertical axis which is offset from the mid-point of the runner.
Claim 4
Dependent Claim
37 words
A training device according to claim 1, including cooperable stop members on each of said rotatable runners and on the associated support legs adapted to engage and thereby limit the extent of rotational movement of said runners.
Claim 5
Dependent Claim
48 words
A training device according to claim 1, wherein each of said support legs includes upper and lower telescoping leg elements and means for releasably locking said leg elements in any one of a plurality of positions relative to each other to thereby establish the elevation of said frame.
Claim 6
Dependent Claim
51 words
A training device according to claim 4, wherein a depending pipe flange having a threaded lower section is provided on said frame at each corner thereof, each of said upper leg elements being threaded to threadedly engage one of said pipe flanges to thereby secure said support legs to said frame.
Claim 7
Dependent Claim
47 words
A training device according to claim 4, wherein said locking means includes a spring loaded locking pin carried by one of said upper and lower leg elements and a series of vertically spaced apertures in the other of said leg elements dimensioned to receive said locking pin.
