Abstract
Abstract An exercising device simulating walking up steps. A pair of step treads are rigidly supported at a slight angle on the ends of a pair of step arms pivoted at the other ends on the bight portion of a "U"-shaped frame. A rocker plate is connected between the step arms and is adjustably braked by a pair of brake shoes rigidly connected to a cross arm connecting the legs of the "U". The cross arm is selectively attached to different portions of the arms of the "U"-shaped frame together with the rocker plate and brake shoes for adjusting the height of the steps. Support blocks are connected underneath the step treads to provide different angles of inclination of the step treads and accomplished by partial rotation of the blocks.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
135 words
A foot and leg exercising device for simulating walking up steps, comprising a support having parallel side arms interconnected at one end by a right angularly extending pivot arm, a pair of step treads attached to one end of a pair of step arms, said step arms being loosely pivoted at their other end to said pivot arm, a cross arm having ends connected to an intermediate portion of said side arms, a brake shoe upstanding from and rigidly connected to the central portion of said cross arm, a rocker plate pivotally mounted on said brake shoe and having openings at the ends thereof which loosely fit on said step arms, and bolt means for selectively compressing said rocker plate against said brake shoe to vary the resistance against rocker movements of said rocker plate.
Claim 2
Dependent Claim
135 words
A foot and leg exercising device for simulating walking up steps, comprising a support having parallel side arms interconnected at one end by a right angularly extending pivot arm, a pair of step treads attached to one end of a pair of step arms, said step arms being loosely pivoted at their other end to said pivot arm, a cross arm having ends connected to an intermediate portion of said side arms, a brake shoe upstanding from and rigidly connected to the central portion of said cross arm, a rocker plate pivotally mounted on said brake shoe and having openings at the ends thereof which loosely fit on said step arms, and bolt means for selectively compressing said rocker plate against said brake shoe to vary the resistance against rocker movements of said rocker plate.
Claim 3
Dependent Claim
38 words
An exercising device as recited in claim 1 together with means for adjusting the longitudinal position of attachment of said cross arm to said side arms so as to vary the height of movement of said step treads.
Claim 4
Dependent Claim
20 words
An exercising device as recited in claim 2 wherein said step treads are angularly disposed relative to said step arms.
Claim 5
Dependent Claim
36 words
An exercising device as recited in claim 2 wherein said support is in the form of piping connected by elbows and wherein said elbows have a third arm extending downwardly at right angles to form legs.
