Abstract
Abstract Exercising apparatus having a frame made of detachably, telescopically coupled tubular members. Connected to the top most cross member of the frame is a substantially rigid spring member that extends between and removably connects the frame with a door. The substantially rigid spring member includes two parallel spaced arms. At the opposite end of the member are two longitudinally spaced elements that engage respectively the front surface of a door, the top of the door and the upper back surface of a door. With the substantially rigid spring member in place for use by an exerciser the frame will be spaced from the top of the door.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
A door-stabilized, floor supported horizontal bar exercising apparatus comprising a closed rectangular frame having approximately the dimensions of a door and consisting of spaced vertical tubular side members and spaced horizontal top and bottom tubular cross members, substantially rigid means for releasably attaching the frame to a door, said substantially rigid means comprising, at least one substantially rigid member having means at one end for detachably connecting the substantially rigid means to the top tubular cross member, and said substantially rigid means having means at its opposite end for detachably connecting it directly to the upper marginal edge portion of a door, said means at the opposite end of said substantially rigid means including means respectively engageable with opposite sides of a door to maintain the top tubular cross member at a selected distance therefrom and to prevent transverse movement of said cross member relative to a door, while supporting said bottom tubular cross member on a floor adjacent a door, and to enable said top tubular cross member to be used for gymnastic exercising upon attachment of the frame to a door.
Claim 2
Dependent Claim
183 words
A door-stabilized, floor supported horizontal bar exercising apparatus comprising a closed rectangular frame having approximately the dimensions of a door and consisting of spaced vertical tubular side members and spaced horizontal top and bottom tubular cross members, substantially rigid means for releasably attaching the frame to a door, said substantially rigid means comprising, at least one substantially rigid member having means at one end for detachably connecting the substantially rigid means to the top tubular cross member, and said substantially rigid means having means at its opposite end for detachably connecting it directly to the upper marginal edge portion of a door, said means at the opposite end of said substantially rigid means including means respectively engageable with opposite sides of a door to maintain the top tubular cross member at a selected distance therefrom and to prevent transverse movement of said cross member relative to a door, while supporting said bottom tubular cross member on a floor adjacent a door, and to enable said top tubular cross member to be used for gymnastic exercising upon attachment of the frame to a door.
Claim 3
Dependent Claim
32 words
Apparatus according to claim 1 in which said tubular members are telescopically and detachably coupled to each other adjacent the corners of said frame to make said frame readily portable and storable.
Claim 4
Dependent Claim
53 words
Apparatus according to claim 1 in which said means at said one end is pivotally mountable on said top tubular cross member and the substantially rigid means is respectively engageable with front and back surfaces of a door and comprises a pair of longitudinally spaced elements extending vertically from said substantially rigid means.
Claim 5
Dependent Claim
118 words
Apparatus according to claim 3 wherein said substantially rigid means comprises a pair of parallel spaced arms connected at said one end by at least one open loop for receiving the top tubular cross member, the free end of one arm of said pair of parallel arms having a vertically extending element and being of a length to permit the element to abut a surface of the door closest to the top tubular cross member, the other arm of said pair of parallel arms being of greater length than said one arm and having a depending element at its free end for engaging the opposite surface of a door when supported on a top edge of a door.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1 in which said bottom tubular cross member is crowded into a horizontal corner between a door and a floor.
Claim 7
Dependent Claim
68 words
Apparatus according to claim 1 including at least an additional substantially rigid means for detachable connection at one end to the bottom tubular cross member for detachable connection at its other end to the lower marginal edge portion of a door and said additional substantially rigid means including means for maintaining said bottom cross member at a spaced distance from the door and against transverse movement relative thereto.
