Abstract
Abstract An exercise frame adapted to be stood on a floor and leaned against a wall and be supported thereby, which frame includes laterally offset side rails adapted to be gripped by a person exercising on the frame. A foot support board near a lower end of the frame is secured to the side rails to provide a surface upon which the person exercising with the frame may stand, and a crossbrace is connected to the side rails near the upper end of the frame to add strength and rigidity thereto. The space circumscribed by the side rails, foot support board and cross brace is free of obstructions to permit freedom of movement of one exercising on the frame.

Claim 1
Independent Claim
349 words
An inclined portable exercise frame designed to engage and be supported by a floor surface with the upper end of said exercise frame to be leaned against and braced by a wall such that said exercise frame forms the hypotenuse of a right triangle with said floor and wall forming the right-angled sides, said portable exercise frame comprising: A. a pair of inclined spaced apart tubular side grip rails with each of said side rails having 1. a straight lower side rail section with its bottom end adapted to engage and be supported by a floor surface, and 2. a stand-off strut support at the upper terminal end of each said side rail formed by bending forward at an obtuse angle a portion of each of said side rails equal to approximately onetenth to one-fifth of the length of said side rails with the upper terminal end of each of said stand-off strut extensions of the side rails being provided with friction means of engaging a wall for suppOrt without marring the wall; B. a single flat oblong foot support board transversely mounted between said spaced apart side rails at an intermediate point near the lower end of said side rails, and so positioned with respect to the inclined side rails when the exercise frame is leaned in operative position against a support wall, that the top surface of said foot support board is in substantially a horizontal parallel position with respect to the floor on which the exercise frame is standing; C. an upper transverse cross-brace connected between the spacedapart side rails at an intermediate point from the upper end of each of said spaced apart side rails at a point near the obtuse bend that forms the stand-off strut supports in each of said side rails to impart strength and rigidness to said exercise frame; and D. said foot support, said cross-brace, and said tubular side grip rails enclosing a space which is free of obstructions whereby a user, when standing on said foot support and gripping said rails, may exercise freely and unconstrained, within said space.
Claim 2
Dependent Claim
349 words
An inclined portable exercise frame designed to engage and be supported by a floor surface with the upper end of said exercise frame to be leaned against and braced by a wall such that said exercise frame forms the hypotenuse of a right triangle with said floor and wall forming the right-angled sides, said portable exercise frame comprising: A. a pair of inclined spaced apart tubular side grip rails with each of said side rails having 1. a straight lower side rail section with its bottom end adapted to engage and be supported by a floor surface, and 2. a stand-off strut support at the upper terminal end of each said side rail formed by bending forward at an obtuse angle a portion of each of said side rails equal to approximately onetenth to one-fifth of the length of said side rails with the upper terminal end of each of said stand-off strut extensions of the side rails being provided with friction means of engaging a wall for suppOrt without marring the wall; B. a single flat oblong foot support board transversely mounted between said spaced apart side rails at an intermediate point near the lower end of said side rails, and so positioned with respect to the inclined side rails when the exercise frame is leaned in operative position against a support wall, that the top surface of said foot support board is in substantially a horizontal parallel position with respect to the floor on which the exercise frame is standing; C. an upper transverse cross-brace connected between the spacedapart side rails at an intermediate point from the upper end of each of said spaced apart side rails at a point near the obtuse bend that forms the stand-off strut supports in each of said side rails to impart strength and rigidness to said exercise frame; and D. said foot support, said cross-brace, and said tubular side grip rails enclosing a space which is free of obstructions whereby a user, when standing on said foot support and gripping said rails, may exercise freely and unconstrained, within said space.
Claim 3
Dependent Claim
74 words
The inclined portable exercise frame described in claim 1 with a lower transverse cross-brace connected between the spaced-apart side rails of said exercise frame at an intermediate point from the lower end of each of said spaced-apart side rails just underneath the oblong foot support board in such position and manner as to brace the foot support board and also to increase the strength and rigidness of the lower part of said exercise frame.
Claim 4
Dependent Claim
250 words
a stand-off strut support at the upper terminal end of each said side rail formed by bending forward at an obtuse angle a portion of each of said side rails equal to approximately one-tenth to one-fifth of the length of said side rails with the upper terminal end of each of said stand-off strut extensions of the side rails being provided with friction means of engaging a wall for suppOrt without marring the wall; B. a single flat oblong foot support board transversely mounted between said spaced apart side rails at an intermediate point near the lower end of said side rails, and so positioned with respect to the inclined side rails when the exercise frame is leaned in operative position against a support wall, that the top surface of said foot support board is in substantially a horizontal parallel position with respect to the floor on which the exercise frame is standing; C. an upper transverse cross-brace connected between the spaced-apart side rails at an intermediate point from the upper end of each of said spaced apart side rails at a point near the obtuse bend that forms the stand-off strut supports in each of said side rails to impart strength and rigidness to said exercise frame; and D. said foot support, said cross-brace, and said tubular side grip rails enclosing a space which is free of obstructions whereby a user, when standing on said foot support and gripping said rails, may exercise freely and unconstrained, within said space.
Claim 5
Dependent Claim
250 words
a stand-off strut support at the upper terminal end of each said side rail formed by bending forward at an obtuse angle a portion of each of said side rails equal to approximately one-tenth to one-fifth of the length of said side rails with the upper terminal end of each of said stand-off strut extensions of the side rails being provided with friction means of engaging a wall for suppOrt without marring the wall; B. a single flat oblong foot support board transversely mounted between said spaced apart side rails at an intermediate point near the lower end of said side rails, and so positioned with respect to the inclined side rails when the exercise frame is leaned in operative position against a support wall, that the top surface of said foot support board is in substantially a horizontal parallel position with respect to the floor on which the exercise frame is standing; C. an upper transverse cross-brace connected between the spaced-apart side rails at an intermediate point from the upper end of each of said spaced apart side rails at a point near the obtuse bend that forms the stand-off strut supports in each of said side rails to impart strength and rigidness to said exercise frame; and D. said foot support, said cross-brace, and said tubular side grip rails enclosing a space which is free of obstructions whereby a user, when standing on said foot support and gripping said rails, may exercise freely and unconstrained, within said space.
Claim 6
Dependent Claim
80 words
The inclined portable exercise frame described in claim 1 in which the oblong foot support board is provided with semi-circular cut-out notches and a metal half-tubular anti-twist brace at each end of the foot support board where said foot support board connects to the left and right side rails to further brace and prevent said foot support board from twisting with respect to said left and right side rails when weight and stress are applied to the foot support board.
Claim 7
Dependent Claim
183 words
The portable inclined exercise frame described in claim 1 except that the horizontal foot support board is transversely mounted between the spaced apart side rails by means of a pair of hanger support brackets, with each of said hanger support brackets having: A. a half tubular sleeve-clamp adapted to fit over and be attached to said inclined tubular side grip rails at an intermediate point near the lower end of each of said side rails; B. a generally triangular shaped depending spacer plate extending downward from one side of said half tubular sleeve clamp; C. a horizontal foot board mounting and supporting flange on the inwardly facing side of said triangular shaped depending spacer plate; and D. suitable fastening means for securing said flat oblong foot support board to said horizontal foot board mounting and supporting flange in a fixed relationship to said uniformly spaced apart inclined tubular side rails and to hold said flat oblong foot support board in a secure elevated position substantially horizontal and parallel to the floor surface that supports the lower ends of said inclined tubular side rails.
