Abstract
Abstract An apparatus for training cross-country skiers and ice skaters has a frame having a center support and two bars, the rear ends of which are connected to said frame in such a manner as to be pivotable about vertical axes. The center support and the bars have respective standing surfaces with threaded bores of the attachment of cross-country ski bindings. The bars are held together by at least one spring and support rollers on their forward ends which rotate about horizontal axes. The hip muscles, thigh extensors and gluteal muscles can be exercised with this apparatus.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A training apparatus for cross-country skiers and ice skaters comprising; a frame for setting up on the floor, two elongated bars pivotably supported on the frame at their rear ends with respect to a trainee's orientation, to allow each bar to pivot about a vertical axis, each bar having a standing surface for a trainee, an axle parallel to the longitudinal direction of the respective bar and a wheel supporting the bar at its front end and rotatable about said axle, spring biasing means biasing the two bars toward each other, and stop means on the frame for retaining one of the bars while the other bar is swung away from the retained bar against the action of the spring means, wherein each standing surface is pivotable about an axis parallel to the longitudinal direction of the respective bar.
Claim 2
Dependent Claim
139 words
A training apparatus for cross-country skiers and ice skaters comprising; a frame for setting up on the floor, two elongated bars pivotably supported on the frame at their rear ends with respect to a trainee's orientation, to allow each bar to pivot about a vertical axis, each bar having a standing surface for a trainee, an axle parallel to the longitudinal direction of the respective bar and a wheel supporting the bar at its front end and rotatable about said axle, spring biasing means biasing the two bars toward each other, and stop means on the frame for retaining one of the bars while the other bar is swung away from the retained bar against the action of the spring means, wherein each standing surface is pivotable about an axis parallel to the longitudinal direction of the respective bar.
Claim 3
Dependent Claim
40 words
Apparatus according to claim 1, wherein the stop means are arranged on an elongated center support of the frame, the two bars in their neutral position being symmetrical to a vertical plane containing a longitudinal axis of the center support.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 1, wherein each standing surface has means for attachment of a cross-country ski boot binding means.
Claim 5
Dependent Claim
170 words
A training apparatus for cross-country skiers and ice skaters comprising; a frame for setting up on the floor, two elongated bars pivotably supported on the frame at their rear ends with respect to a trainee's orientation, to allow each bar to pivot about a vertical axis, each bar having a standing surface for a trainee, an axle parallel to the longitudinal direction of the respective bar and a wheel supporting the bar at its front end and rotatable about said axle, spring biasing means biasing the two bars toward each other, and stop means on the frame for retaining one of the bars while the other bar is swung away from the retained bar against the action of the spring means, the stop means being arranged on a center support of the frame, the two bars in a neutral position being symmetrical to a vertical plane containing a longitudinal axis of the center support, wherein the stop means are mechanical stops against which the bars abut in their neutral position.
Claim 6
Dependent Claim
170 words
A training apparatus for cross-country skiers and ice skaters comprising; a frame for setting up on the floor, two elongated bars pivotably supported on the frame at their rear ends with respect to a trainee's orientation, to allow each bar to pivot about a vertical axis, each bar having a standing surface for a trainee, an axle parallel to the longitudinal direction of the respective bar and a wheel supporting the bar at its front end and rotatable about said axle, spring biasing means biasing the two bars toward each other, and stop means on the frame for retaining one of the bars while the other bar is swung away from the retained bar against the action of the spring means, the stop means being arranged on a center support of the frame, the two bars in a neutral position being symmetrical to a vertical plane containing a longitudinal axis of the center support, wherein the stop means are mechanical stops against which the bars abut in their neutral position.
Claim 7
Dependent Claim
32 words
Apparatus according to claim 4, wherein a further standing surface is mounted on the center support at approximately the same distance from the pivot axes as the standing surfaces of the bars.
Claim 8
Dependent Claim
155 words
A training apparatus for cross-country skiers and ice skaters comprising; a frame for setting up on the floor, two elongated bars pivotably supported on the frame at their rear ends with respect to a trainee's orientation, to allow each bar to pivot about a vertical axis, each bar having a standing surface for a trainee, an axle parallel to the longitudinal direction of the respective bar and a wheel supporting the bar at its front end and rotatable about said axle, spring biasing means biasing the two bars toward each other, and stop means on the frame for retaining one of the bars while the other bar is swung away from the retained bar against the action of the spring means, wherein each standing surface is pivotable about an axis parallel to the longitudinal direction of the respective bar between two end positions one of which end positions being where the standing surface is horizontal.
