Abstract
Abstract A platform, a pair of skis, and individual support means for supporting each ski for pivoting and rocking motion about mutually perpendicular axes of rotation while permitting limited fore and aft translational movements of each ski independently of the other ski relative to its respective longitudinal axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
216 words
A training device for simulating actual skiing conditions and comprising a platform having a generally planar upper surface, a pair of separate elongated simulated skis, and individual support means for each of said skis for mounting each of said skis in elevated position above said planar platform surface, said support means including independent front and rear supports for each ski, said front and rear supports providing bearing support for its respective ski along its longitudinal axis and supporting each ski along its longitudinal axis in spaced relation above said planar platform surface, said front support for each ski including a fixed ball secured to one of the ski and platform members and a guideway formed in the other of the ski and platform members for receiving the ball, said rear support for each ski including a fixed ball secured in captured underlying relation to a center heel portion of each ski, said front and rear supports cooperating to support their respective ski for universal pivotal movements on the planar platform surface including rocking movements of each ski independently of the other ski in opposite lateral directions relative to the longitudinal axis of each ski while also permitting fore and aft translational movements in opposite linear directions longitudinally of each ski and independently of the other ski.
Claim 2
Dependent Claim
216 words
A training device for simulating actual skiing conditions and comprising a platform having a generally planar upper surface, a pair of separate elongated simulated skis, and individual support means for each of said skis for mounting each of said skis in elevated position above said planar platform surface, said support means including independent front and rear supports for each ski, said front and rear supports providing bearing support for its respective ski along its longitudinal axis and supporting each ski along its longitudinal axis in spaced relation above said planar platform surface, said front support for each ski including a fixed ball secured to one of the ski and platform members and a guideway formed in the other of the ski and platform members for receiving the ball, said rear support for each ski including a fixed ball secured in captured underlying relation to a center heel portion of each ski, said front and rear supports cooperating to support their respective ski for universal pivotal movements on the planar platform surface including rocking movements of each ski independently of the other ski in opposite lateral directions relative to the longitudinal axis of each ski while also permitting fore and aft translational movements in opposite linear directions longitudinally of each ski and independently of the other ski.
Claim 3
Dependent Claim
49 words
The training device of claim 1 further including stop means mounted on the platform and cooperating with the skis for limiting pivotal movements thereof in opposite angular directions about axes established by the front ball supports of the skis in perpendicular relation to the longitudinal axes of the skis.
Claim 4
Dependent Claim
37 words
The training device of claim 1 wherein the skis each carry adjustable foot securing means, and wherein the skis are each bodily removable from the platform for quick and easy adjustment of their respective foot securing means.
Claim 5
Dependent Claim
39 words
The training device of claim 1 wherein the guideway means for each ski is formed in a bottom surface thereof, and wherein the front ball support for each ski comprises a fixed bearing ball rigidly secured to the platform.
Claim 6
Dependent Claim
44 words
The training device of claim 1 wherein each skI is provided with adjustable foot securing means including a toe clamp, and wherein the front ball support and cooperating guideway means for each ski is disposed forwardly of the toe clamp of its respective ski.
Claim 7
Dependent Claim
78 words
The training device of claim 1 wherein forward and rear stop surfaces are provided in the guideway means engageable with the front ball support for establishing limit positions for translational movements of each ski in opposite linear directions, the guideway means of each ski being dimensioned and configured relative to its cooperating front ball support to limit the freedom of translational motion of each ski to only one line of movement which is coincident with its longitudinal axis.
