Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
202 words
In an animal exercising device having a movable floor, with side walls and cooperating end walls for containing the animal on the floor, the improvement comprising: frame means; a first roller means attached to said frame means to rotate about an axis; a second roller means attached to said frame means in spaced relation to said first roller means to rotate about an axis parallel to the axis of rotation of said first roller means; an endless belt looped around said first and said second roller means, the upper run of said belt comprising said movable floor for supporting the animal; a plurality of closely spaced supporting roller means disposed beneath said belt at least in the region thereof defining the movable floor for supporting said animal, each said supporting roller means having stub axles extending from the opposite ends thereof; and means yieldably supporting each of the stub axles of said supporting roller means to permit each of said supporting roller means to yield independently of the others and the stub axles at opposite ends of each of said supporting roller means to yield relative to one another to effectively cushion the impact of the weight of the animal during exercise.
