Abstract
Abstract A leg stretching exercise device is provided which has two platforms, each adapted to support a foot of an exerciser. Each platform is provided with ball casters which provide support and allow free movement in a mutual plane. The platforms are attached so they may be placed in touching relationship and moved apart a predetermined distance by the exerciser. A rope connects a single point on each platform. The connecting rope defines a loop which passes through eyelets, secured to each platform. An adjustable connection is provided for varying the size of the loop as desired.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
148 words
A leg stretching exercise device for use on a floor comprising: a pair of platform means, each said platform means adapted to support a foot of an exerciser on the upper surface of each of said platform; means during an exercise program means for independently rollingly supporting each said platform means on a floor, and permitting the pair of platform means to move freely in any direction on a floor; non-rigid means which is non-rigid and non-electric for connecting said platforms whereby said pair of platform means may be placed in touching relationship and moved apart under the operation of a user's legs, and each platform means of said pair of platform means being freely moved in any direction upon a floor; and, means for adjusting said connecting means to limit the spaced apart distance that each platform means of said pair of platform means may be moved.
Claim 2
Dependent Claim
148 words
A leg stretching exercise device for use on a floor comprising: a pair of platform means, each said platform means adapted to support a foot of an exerciser on the upper surface of each of said platform; means during an exercise program means for independently rollingly supporting each said platform means on a floor, and permitting the pair of platform means to move freely in any direction on a floor; non-rigid means which is non-rigid and non-electric for connecting said platforms whereby said pair of platform means may be placed in touching relationship and moved apart under the operation of a user's legs, and each platform means of said pair of platform means being freely moved in any direction upon a floor; and, means for adjusting said connecting means to limit the spaced apart distance that each platform means of said pair of platform means may be moved.
Claim 3
Dependent Claim
33 words
The exercise device of claim 1 wherein said means for rollingly supporting comprises: at least four casters attached to the under side of each platform of said pair of platform means said platform.
Claim 4
Dependent Claim
56 words
The exercise device of claim 1 wherein said non-rigid means for attaching each said platform means of said pair of platform means comprises: an eyelet connected to each said platform means; a rope passing through the eyelet connected to each said platform means and being joined together to define a loop by said means for adjusting.
