Skating motion exercising machine

A skating training apparatus includes rotating gears positioned in a generally horizontal plane. Linear supporting struts are pivotally attached to the gears for movement therewith and a motion restricting device is engaging with the liner supporting struts and adapted for restricting the linear supporting struts to a combination of pivotal and linear translational motion. Pivots engage the linear supporting struts and restrict it to pivotal motion at one end. Foot rests are mounted on the linear supporting struts at an end opposite to the pivots. The rotating gears, linear supporting struts, motion restricting device and pivots are mutually interconnected for moving the foot rests in a skating motion as driven by a person's feet while training on the apparatus.

What is claimed is:

1. An apparatus for physical training, the apparatus comprising:

rotating means positioned in a generally horizontal plane;

linear supporting means pivotal on the rotating means for movement therewith;

motion restricting means engaging the liner supporting means and adapted for restricting the linear supporting means to pivotal and linear translational motion;

pivoting means engaging the linear supporting means and adapted for restricting the linear supporting means to pivotal motion; and

foot rest means engaging the linear supporting means distally from the motion restricting means and the pivoting means;

the rotating means, linear supporting means, motion restricting means and pivoting means mutually interconnected for moving the foot rest means in a skating motion.

2. The apparatus of claim 1 wherein the rotating means is a pair of mutually engaged circular gears rotationally joined to a rigid support plate for rotation about spaced apart gear axles, the gears positioned for rotation in a generallyhorizontal plane.

3. The apparatus of claim 2 wherein the linear supporting means is a pair of elongate rigid struts, each one of the struts medially thereat and pivotally joined to one of the gears.

4. The apparatus of claim 3 wherein the motion restricting means is a pair of strut guides, each one of the guides pivotally joined to the support plate for rotational motion about spaced apart guide axles, the guides each adapted for receivingone of the struts distally therewith, in linear sliding and pivotal motion.

5. The apparatus of claim 4 wherein the foot rest means is a pair of support platforms, together adapted for supporting an athlete, each one of the platforms joined with one of the struts proximally thereon.

6. The apparatus of claim 2 wherein the motion restricting means is a pair of strut guides, each one of the guides pivotally joined to one of the gears for rotational motion about a guide axle.

7. The apparatus of claim 6 wherein the linear supporting means is a pair of elongate rigid strut assemblies comprising an outer tube and, therewithin, a proximal end of an inner shaft engaged therewith for sliding telescopic linear motionrelative to the outer tube, each one of the outer tubes of the strut assemblies distally thereat, joined integrally to one of the strut guides, each one of the inner shafts distally therewith, pivotally joined to the support plate.

8. The apparatus of claim 7 wherein the foot rest means is a pair of support platforms, together adapted for supporting an athlete, each one of the platforms joined with one of the outer tubes proximally thereon.
