Abstract
Abstract A portable exercise device used in pairs for performing various exercises such as pushups, handstands and the like which includes a metal tube having a central portion and a pair of substantially identical U-shaped portions on opposite sides of the central portion which are bent into an angularly disposed relationship to define three sides in a triangular configuration with the central and U-shaped portions providing handgrip areas covered with anti-slip material so that each of the sides are adapted for overlying engagement with a supporting surface to selectively position one of the handgrip areas in an elevated position for gripping by the hand of a user.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
A portable exercise device comprising an elongated body member of rigid material so as to rigidly support the weight of an exerciser using the device, said body member having a substantially straight central portion forming a handgrip area, a first U-shaped portion emanating directly from one side of said central portion and terminating in a first straight free end leg portion, a second U-shaped portion emanating directly from the other side of said central portion and terminating in a second straight free end leg portion, each of said leg portions froming handgrip areas for the exerciser, said first U-shaped portion and said central portion lying in a second plane, said second U-shaped portion and said central portion lying in a second plane angularly disposed to said first plane and toward said first leg portion whereby said second leg portion is spaced above said first plane thereby providing a rigid triangular structure.
Claim 2
Dependent Claim
151 words
A portable exercise device comprising an elongated body member of rigid material so as to rigidly support the weight of an exerciser using the device, said body member having a substantially straight central portion forming a handgrip area, a first U-shaped portion emanating directly from one side of said central portion and terminating in a first straight free end leg portion, a second U-shaped portion emanating directly from the other side of said central portion and terminating in a second straight free end leg portion, each of said leg portions froming handgrip areas for the exerciser, said first U-shaped portion and said central portion lying in a second plane, said second U-shaped portion and said central portion lying in a second plane angularly disposed to said first plane and toward said first leg portion whereby said second leg portion is spaced above said first plane thereby providing a rigid triangular structure.
Claim 3
Dependent Claim
20 words
An exercise device in accordance with claim 1 wherein said body member comprises a metal tube of uniform, cross-sectional shape.
Claim 4
Dependent Claim
28 words
An exercise device in accordance with claim 2 wherein said end portions of said U-shaped portions are disposed in substantially parallel, spaced-apart relationship and extend in opposite directions.
Claim 5
Dependent Claim
21 words
An exercise device in accordance with claim 3 including friction increasing means on said tube within each of said handgrip areas.
Claim 6
Dependent Claim
20 words
An exercise device in accordance with claim 1 wherein all of said handgrip areas are of substantially the same length.
Claim 7
Dependent Claim
34 words
An exercise device in accordance with claim 4 wherein said friction increasing means comprise a sleeve of anti-slip material telescopically fitted onto the outer surface of said tube within each of said handgrip areas.
Claim 8
Dependent Claim
19 words
An exercise device in accordance with claim 6 wherein each of said U-shaped portions are of substantially identical shape.
Claim 9
Dependent Claim
16 words
An exercise device in accordance with claim 7 wherein said sleeves are formed of foam rubber.
Claim 10
Dependent Claim
76 words
The device of claim 1 wherein said second leg is substantially equidistant from said first leg portion and said central portion and forming a third plane with said first leg portion thereby providing a rigid triangular configuration symmetrical about said central portion whereby any of said planes is adapted for overlying engagement with a supporting surface to selectively position one of said handgrip areas in an elevated position for gripping by the hand of an exerciser.
