Abstract
Abstract A physical exercising device is provided comprising a padded wedge-shaped base and a spring-biased metal exercise bar. The exercise bar is attached near the wedge's apex and extends lengthwise parallel to the device at a predetermined distance from the wedge. The physical exercising device has its base formed from a lightweight material and additionally may have its body support surfaces covered with a layer of carpet or foam padding. The spring which has its one end attached to the exercise bar has its opposite end secured to the end panel of the wedge-shaped base to provide a biasing force. The ends of the metal bar are inserted through apertures in the end panel and terminate in the interior of the physical exercising device. The exercise bar may be of a unitary piece of tubular metal or a single metal tube with two gripping portions which may or may not be independently operable.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
175 words
A physical exercising device comprising a base unit of elongated, wedge-shaped configuration having a generally triangular cross-section, said base unit including two upwardly inclined body supporting surfaces converging at an apex a predetermined distance above a bottom adapted to rest on a supporting surface, and an exercise bar pivotably mounted on said base unit for swinging movement about a horizontal pivot axis extending longitudinally of said base unit, said exercise bar including a gripping portion extending longitudinally of said base unit and supported at a predetermined distance with respect to the horizontal pivot axis of said bar and to a body supporting surface of said base unit to permit swinging of said bar from one body supporting surface to the other of said base unit over the apex thereof in an arc about said pivot axis such that said gripping portion will contactingly engage with the uppermost surface portions of a person's leg adjacent the ankles when a person's legs are extended over the base unit with the knees disposed at approximately the apex thereof.
Claim 2
Dependent Claim
175 words
A physical exercising device comprising a base unit of elongated, wedge-shaped configuration having a generally triangular cross-section, said base unit including two upwardly inclined body supporting surfaces converging at an apex a predetermined distance above a bottom adapted to rest on a supporting surface, and an exercise bar pivotably mounted on said base unit for swinging movement about a horizontal pivot axis extending longitudinally of said base unit, said exercise bar including a gripping portion extending longitudinally of said base unit and supported at a predetermined distance with respect to the horizontal pivot axis of said bar and to a body supporting surface of said base unit to permit swinging of said bar from one body supporting surface to the other of said base unit over the apex thereof in an arc about said pivot axis such that said gripping portion will contactingly engage with the uppermost surface portions of a person's leg adjacent the ankles when a person's legs are extended over the base unit with the knees disposed at approximately the apex thereof.
