Abstract
Abstract An exercise device in the form of a bracket utilized in conjunction with a rope doubled back upon itself to form a bight engaging one end of the bracket. The strands of the rope immediately adjacent the bight are twisted to provide a plurality of helical turns extending generally the length of the bracket. The opposite end of the bracket is arranged to guide the separate strands of the rope so that tension applied to one or the other of the strands effects longitudinal sliding movement of the rope to create frictional resistance between the contiguous strands. The amount of such frictional resistance is controlled by the number of helical turns into which a portion of the rope is twisted, and the amount of tension applied to the rope strands.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
An exercising device adapted to permit controlled variation in the amount of force to be exerted to perform a given exercise, comprising: a. a bracket; b. means for anchoring the bracket to a supporting structure; and C. a flexible line having terminal ends and a bight therebetween engaging the bracket, the terminal ends of the line extending generally in the same direction with portions of the line on opposite sides of the bight being contiguous and intertwined about each other when taut, and movable in opposite directions to generate friction between said contiguous portions of said terminal ends when said terminal ends are moved in opposite directions.
Claim 2
Dependent Claim
107 words
An exercising device adapted to permit controlled variation in the amount of force to be exerted to perform a given exercise, comprising: a. a bracket; b. means for anchoring the bracket to a supporting structure; and C. a flexible line having terminal ends and a bight therebetween engaging the bracket, the terminal ends of the line extending generally in the same direction with portions of the line on opposite sides of the bight being contiguous and intertwined about each other when taut, and movable in opposite directions to generate friction between said contiguous portions of said terminal ends when said terminal ends are moved in opposite directions.
Claim 3
Dependent Claim
63 words
The combination according to claim 1, in which said bracket comprises an elongated bar extending generally parallel to said intertwined portions when taut, and means are provided at opposite ends of the bar supporting and engaging the line in a manner to permit longitudinal displacement of the line when one or the other of the terminal ends of the line is moved longitudinally.
Claim 4
Dependent Claim
104 words
The combination according to claim 1, which said bracket comprises an elongated bar having a looped portion at each end, said bight engaging one of said looped portion, and said line constituting a rope, said contiguous intertwined portions of the terminal ends of the rope on opposite sides of the bight being twisted to provIde a selected number of contiguous spiral turns, portions of said rope remote from said bight slidably engaging the other of said looped portions whereby the terminal ends of the rope may be displaced longitudinally to generate frictional resistance to such displacement between the contiguous spiral turns of the rope.
Claim 5
Dependent Claim
31 words
The combination according to claim 1, in which said bracket comprises an elongated bar having a looped portion at each end thereof, said looped portions lying in substantially the same plane.
Claim 6
Dependent Claim
49 words
The combination according to claim 1, in which said bracket comprises an elongated tubular member, the bight of said line slidably engaging said tubular member adjacent one end thereof and the contiguous line portions on opposite sides of the bight are enclosed within the tubular portion of the bracket.
Claim 7
Dependent Claim
97 words
The combination according to claim 1, in which said bracket comprises an elongated tubular member, an anchor cap on one end of the tubular member including means about which the bight in said line may slide, an apertured guide cap on the other end of the tubular member through which said terminal ends extend, said intertwined portions of said line being between said anchor and guide caps and twisted one upon the other to provide frictional contiguity between adjacent strands of said line when said terminal ends are moved in opposite directions with respect to each other.
Claim 8
Dependent Claim
93 words
The combination according to claim 6, in which said guide cap is provided with apertures spaced on opposite sides of the longitudinal axis of the tubular member so that adjacent portions of the line pass through said apertures on opposite sides of said axis, and said guide cap is rotatably adjustable on the tubular member to increase or decrease the number of spiral turns into which the line is twisted so as to controllably vary the frictional resistance between said contiguous spiral turns when the terminal ends of the line are moved longitudinally.
