Abstract
Abstract Disclosed herein is an abdominal waist exercising device characterized in that exercise motions developed by the working against of weights is ultimately transferred from the back of the knee to exercising muscles throughout the groin area. The machine is comprised of a cushion bar oriented and nested, against the hock of the knee connected by a linkage to a counter balanced cam which in turn is connected by a cable element through a series of pulleys and ultimately to a plurality of weights which are constrained to translate in a vertical direction only. The person using the machine is placed on a bench having a back portion capable of adjustment whereby the back of the person may be offset relative to the horizontal plane. Hand grips are further provided for additional support during the exercise.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
231 words
An abdominal waist machine comprising a bench, only one padded bar overlying and extending transversely of said bench for receiving the back of the knees of a user, support bars connected at opposed end extremities of said padded bar, said support bars are connected to an axle on opposed sides of said bench carried on a frame means, a cam disposed on each axle and capable of rotating with said axle, a cable connected to each said cam, and variable weights connected to each cable at an extremity remote from said cam in which said weights are constrained to move in a substantially vertical direction whereby when said padded bar is move, said weights will translate in a vertical direction, and resistance in moving said padded bar will vary as a function of the cam and its contour and in which said bench is provided with a back portion capable of angular orientation with respect to a horizontal plane defined by an apertured shaft disposed transverse to and below a longitudinal extent of said back supported on said frame means, an adjusting bar depending from a bottom face of said back portion having plural holes along its length, said adjusting bar slideably disposed in a first said shaft aperture, and a locking pin extendable through one of said holes to lock said shaft to said bar through a second said aperture.
Claim 2
Dependent Claim

The device of claim 2 in which said cables change direction in going from said cam to said weights through pulleys.
Claim 5
Dependent Claim
31 words
The device of claim 3 in which said support bars connected to said padded bar are U-shaped and a stop member is disposed on said frame means to limit its travel.
