Abstract

Abstract The embodiment of the invention disclosed herein is directed to a rope lock device for receiving a length of relatively small diameter flexible rope and holding the rope against movement. The rope lock device is formed of a molded plastic structure having a yieldable, central support member from which extends a pair of spaced apart arms. Also extending from the central support member, in the opposite direction of said arms, are a pair of spaced apart movable gripping members. Positioned between the movable gripping members is a substantially stationary gripping member. The movable gripping members have aligned apertures therethrough while the stationary gripping member has an aperture which is substantially completely out of registry with the apertures of the movable member when the arms are in their neutral position. Squeezing of the arms will deflect the movable members away from the fixed member and result in placing the apertures substantially in registry with one another so that a rope segment or segments passing through the apertures is easily moved. The plastic structure is molded so that release of the arms causes automatic closure of the rope lock device.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 277 words
In a rope lock device for receiving a length of flexible rope and holding the rope against movement until selectively released therefrom, the combination comprising: a yieldable, central support member, a pair of spaced apart arm means secured to said yieldable, central support member and extending therefrom in a first direction selectively to be pressed together from a neutral position for bending of said yieldable, central support member, first and second spaced apart, movable gripping members secured to said yieldable, central support member and extending therefrom in a second direction, said first and second gripping members having aligned apertures formed therethrough of a size to receive at least one length of a rope of given diameter, said first and second spaced apart gripping members being movable away from and toward one another upon pressing and releasing, respectively, of said arm means, and a third gripping member secured to said yieldable, central support member to be positioned between said first and second spaced apart movable gripping members, said third gripping member having an aperture therethrough which is substantially completely out of registry with the apertures through said first and second gripping members when said pair of arms are in their neutral position for forming a bight portion of the rope segment passing through said apertures of said first, second and third gripping means to lock the rope in place, the apertures of said first, second and third gripping members being placed in substantial registry with one another when said arm means are pressed together, thereby removing said bight portion from said rope segment for releasing the rope for free movement through said first, second and third gripping members.
Claim 2
Dependent Claim 277 words
In a rope lock device for receiving a length of flexible rope and holding the rope against movement until selectively released therefrom, the combination comprising: a yieldable, central support member, a pair of spaced apart arm means secured to said yieldable, central support member and extending therefrom in a first direction selectively to be pressed together from a neutral position for bending of said yieldable, central support member, first and second spaced apart, movable gripping members secured to said yieldable, central support member and extending therefrom in a second direction, said first and second gripping members having aligned apertures formed therethrough of a size to receive at least one length of a rope of given diameter, said first and second spaced apart gripping members being movable away from and toward one another upon pressing and releasing, respectively, of said arm means, and a third gripping member secured to said yieldable, central support member to be positioned between said first and second spaced apart movable gripping members, said third gripping member having an aperture therethrough which is substantially completely out of registry with the apertures through said first and second gripping members when said pair of arms are in their neutral position for forming a bight portion of the rope segment passing through said apertures of said first, second and third gripping means to lock the rope in place, the apertures of said first, second and third gripping members being placed in substantial registry with one another when said arm means are pressed together, thereby removing said bight portion from said rope segment for releasing the rope for free movement through said first, second and third gripping members.
Claim 3
Dependent Claim 41 words
In the rope lock device as set forth in claim 1 wherein said yieldable, central support member, said pair of spaced apart arm means, said first, second and third gripping members are formed as an integral unit of molded plastic material.
Claim 4
Dependent Claim 61 words
In the rope lock device as set forth in claim 1 wherein said pair of spaced apart arm means are substantially parallel to one another in their neutral position and wherein said first and second gripping members are diverging slightly outward from said central support member when forming said bight portion within the rope segment for locking the rope against movement.
Claim 5
Dependent Claim 35 words
In the rope lock device as set forth in claim 3 wherein said first and second gripping members are spaced apart a distance less than the distance between said pair of spaced apart arm means.
Claim 6
Dependent Claim 62 words
In the rope lock device as set forth in claim 1 further including a flexible connecting member extending between free ends of said pair of spaced apart arm means and secured thereto to be compressibly deformed when said arm means are pressed together for releasing the bight portion formed within the rope segment passing through said first, second and third gripping members.
Claim 7
Dependent Claim 48 words
In the rope lock device as set forth in claim 5 wherein said flexible connecting member is formed as an integral part with the terminating ends of said arm means and serves to provide outward bias to the arm means for maintaining the arms in their neutral position.
Claim 8
Dependent Claim 50 words
In the rope lock device as set forth in claim 1 wherein said first, second and third gripping members are formed of material having a predetermined thickness, the area immediately adjacent the periphery of the apertures through said first, second and third gripping members being less than said predetermined thickness.
Claim 9
Dependent Claim 48 words
In the rope lock device as set forth in claim 1 wherein the apertures passing through said first, second and third gripping members are elongated and have a longitudinal extent of about twice that of said given diameter of said rope to receive the lengths of said rope.
Claim 10
Dependent Claim 47 words
In the rope lock device as set forth in claim 1 further including stiffener rib means formed along each of said pair of spaced apart arms to reduce flexure of the arms thereby insuring flexure of said yieldable, central support member during pressing of said arms together.
