Abstract
Abstract Exercise apparatus for attachment to an overhead support or frame comprising a pair of clamps and an elongated bar held horizontally at each end thereof by the clamps. Each clamp comprises a pair of support members having apertured lower ends concentrically overlapping to receive an end of the bar. Intermediate portions of the support members are angled such that the apexes of the angles point away from each other. The clamps are further secured on the bar by a pair of yokes disposed one across each end of the bar. A pair of set screws through each of the yokes abut the underside of the overhead frame so as to stabilize the position of the clamps below the frame.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
165 words
Exercise apparatus for attachment to an overhead frame comprising: a pair of clamps and an elongated first bar held horizontally at each end thereof by said clamps, each clamp comprising a pair of rigid support members having apertured lower ends concentrically overlapping to receive an end of said bar, intermediate portions of said support members being angled such that the apexes of the angles point away from each other, the upper ends of said support members defining means for gripping a horizontal surface of said overhead frame, screw means operatively connected to each of said lower ends below and laterally of said bar, whereby rotation of said bar in said clamps is prevented and said clamps are securable on said surface, said apparatus further including a pair of yokes disposed one across each end of said bar and a pair of set screws threadably engaging each yoke and abutting the underside of said overhead frame, whereby said clamps are further securable on said horizontal surface.
Claim 2
Dependent Claim
165 words
Exercise apparatus for attachment to an overhead frame comprising: a pair of clamps and an elongated first bar held horizontally at each end thereof by said clamps, each clamp comprising a pair of rigid support members having apertured lower ends concentrically overlapping to receive an end of said bar, intermediate portions of said support members being angled such that the apexes of the angles point away from each other, the upper ends of said support members defining means for gripping a horizontal surface of said overhead frame, screw means operatively connected to each of said lower ends below and laterally of said bar, whereby rotation of said bar in said clamps is prevented and said clamps are securable on said surface, said apparatus further including a pair of yokes disposed one across each end of said bar and a pair of set screws threadably engaging each yoke and abutting the underside of said overhead frame, whereby said clamps are further securable on said horizontal surface.
Claim 3
Dependent Claim
165 words
Exercise apparatus for attachment to an overhead frame comprising: a pair of clamps and an elongated first bar held horizontally at each end thereof by said clamps, each clamp comprising a pair of rigid support members having apertured lower ends concentrically overlapping to receive an end of said bar, intermediate portions of said support members being angled such that the apexes of the angles point away from each other, the upper ends of said support members defining means for gripping a horizontal surface of said overhead frame, screw means operatively connected to each of said lower ends below and laterally of said bar, whereby rotation of said bar in said clamps is prevented and said clamps are securable on said surface, said apparatus further including a pair of yokes disposed one across each end of said bar and a pair of set screws threadably engaging each yoke and abutting the underside of said overhead frame, whereby said clamps are further securable on said horizontal surface.
Claim 4
Dependent Claim
165 words
Exercise apparatus for attachment to an overhead frame comprising: a pair of clamps and an elongated first bar held horizontally at each end thereof by said clamps, each clamp comprising a pair of rigid support members having apertured lower ends concentrically overlapping to receive an end of said bar, intermediate portions of said support members being angled such that the apexes of the angles point away from each other, the upper ends of said support members defining means for gripping a horizontal surface of said overhead frame, screw means operatively connected to each of said lower ends below and laterally of said bar, whereby rotation of said bar in said clamps is prevented and said clamps are securable on said surface, said apparatus further including a pair of yokes disposed one across each end of said bar and a pair of set screws threadably engaging each yoke and abutting the underside of said overhead frame, whereby said clamps are further securable on said horizontal surface.
Claim 5
Dependent Claim
34 words
The exercise apparatus of claim 1 wherein said lower ends of said support members below said apertures are split and adapted to receive said screw means for biasing the split ends towards each other.
Claim 6
Dependent Claim
14 words
The exercise apparatus of claim 2 wherein said screw means comprises an Allen screw.
Claim 7
Dependent Claim
14 words
The exercise apparatus of claim 1 wherein said screw means comprises a tap screw.
Claim 8
Dependent Claim
26 words
The exercise apparatus of claim 1 further including a second elongated bar and a pair of hangers for suspending said second bar from said first bar.
Claim 9
Dependent Claim

The exercise apparatus of claim 5 including means on said hangers for locking said second bar in position below said first bar.
Claim 10
Dependent Claim
25 words
The exercise apparatus of claim 6 wherein said locking means comprises a split binding on the upper end of at least one of said hangers.
Claim 11
Dependent Claim
42 words
The exercise apparatus of claim 5 wherein the lower ends of said hangers below said second bar are split and adapted to receive an Allen screw for biasing the split ends towards each other whereby rotation of said second bar is prevented.
Claim 12
Dependent Claim
16 words
The exercise apparatus of claim 8 wherein said bars are each provided with a non-slip surface.
