Abstract

Abstract A rope holding device having a resilient cylindrical-shaped cam mounted on a generally L-shaped bracket. A pair of discs is mounted on the circular ends of the cam by a pin. The pin eccentrically mounts the cam on one leg of the bracket for pivotal movement of the cam into clamping engagement with the other leg of the bracket for gripping a portion of a rope therebetween. The rope forms a groove in the cylindrical engaging surface of the cam preventing sideways disengagement of the rope, and the compression of the resilient cam by the rope maintains constant pressure on the rope preventing premature disengagement of the rope from its clamped position. A rod may extend radially outwardly from the cylindrical cam surface for locking engagement with notches formed in the clamping leg of the bracket.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 247 words
A rope holding device including generally L-shaped bracket means having first and second legs; a solid cylindrical-shaped cam formed of resilient material and having a pair of spaced flat, circular end surfaces and a smooth, cylindrical side camming surface extending between said end surfaces; pin means extending perpendicularly through the cam end surfaces and eccentrically pivotally mounting the cam on the bracket means first leg, said camming surface being adapted to clamp a rope against the second leg of the bracket means upon rotation of the cam; the cylindrical camming surface having a width greater than the diameter of a rope being clamped, with groove means and spaced ridge means being formed in the cylindrical camming surface due to the resiliency of the cam when said cam clamps a rope against the second leg of the bracket means to prevent sidewise disengagement of the rope from the cam; rod means embedded in the cam and extending radially outwardly from the cylindrical camming surface; the rod means being resiliently mounted on the cam and having limited movement in the axial and circumferential directions with respect to the cam due to the resiliency of the cam; and elongated notch means formed in the bracket means second leg with said rod means being engageable with the notch means to hold the cam in rope clamping position and to permit limited rotation of the cam in both clockwise and counterclockwise directions without the rOd means being disengaged from the notch means.
Claim 2
Dependent Claim 247 words
A rope holding device including generally L-shaped bracket means having first and second legs; a solid cylindrical-shaped cam formed of resilient material and having a pair of spaced flat, circular end surfaces and a smooth, cylindrical side camming surface extending between said end surfaces; pin means extending perpendicularly through the cam end surfaces and eccentrically pivotally mounting the cam on the bracket means first leg, said camming surface being adapted to clamp a rope against the second leg of the bracket means upon rotation of the cam; the cylindrical camming surface having a width greater than the diameter of a rope being clamped, with groove means and spaced ridge means being formed in the cylindrical camming surface due to the resiliency of the cam when said cam clamps a rope against the second leg of the bracket means to prevent sidewise disengagement of the rope from the cam; rod means embedded in the cam and extending radially outwardly from the cylindrical camming surface; the rod means being resiliently mounted on the cam and having limited movement in the axial and circumferential directions with respect to the cam due to the resiliency of the cam; and elongated notch means formed in the bracket means second leg with said rod means being engageable with the notch means to hold the cam in rope clamping position and to permit limited rotation of the cam in both clockwise and counterclockwise directions without the rOd means being disengaged from the notch means.
Claim 3
Dependent Claim 46 words
The construction defined in claim 1 in which the distance of the cam pin means from the bracket means second leg is less than the diameter of the cylindrical cam whereby the camming surface engages the second leg upon rotation in the clockwise and counterclockwise directions.
Claim 4
Dependent Claim 15 words
The construction defined in claim 1 in which the cam is formed of polyurethane material.
Claim 5
Dependent Claim 27 words
The construction defined in claim 1 in which flat reinforcing discs are mounted on each of the cam means flat circular end surfaces by the pin means.
