Abstract
The present invention is a slip-knot grip device which attaches to a rope. The invention consists of a male end cap into which an insert is placed and a female end cap into which an insert is placed with the two end caps being connected by a retaining collar. The inserts have a semi-circle channel on their interior side placed so when the left and right inserts are connected together they form a circle opening through which a rope is placed. The female end cap and the male end cap are turned in opposite directions. This makes the end edges of the combined inserts clasp the rope holding the device in place.
Claims19
A device for gripping elongate articles, said device comprising:
- a male end cap;
- a first insert engaged with the male end cap;
- a first channel defined by said male end cap and said first insert, said first channel being disposed along a longitudinal axis of the device;
- a female end cap, and wherein a portion of the male end cap is receivable within a portion of the female end cap;
- and the male and female end caps are disposed in end-to-end relationship along the longitudinal axis;
- a second insert engaged with the female end cap;
- wherein each of the first and second inserts comprises:
- a body having a first end, a second end, an exterior wall, an inner wall, a first side and a second side;
- and wherein the inner wall of the body is semi-circular when viewed from either of the first and second ends;
- a second channel is defined by said female cap and said second insert;
- said second channel being disposed along the longitudinal axis;
- wherein said first and second channels comprise a rope channel adapted to receive the elongate articles therethrough;
- a longitudinally extending first slot is defined in the male end cap, and wherein the first insert is complementary to the first slot and is removably received therein;
- a longitudinally extending second slot is defined in the female end cap, and the second insert is complementary to the second slot and is removably received therein;
- and wherein each of the male and female end caps has:
- a first end, a second end, an exterior wall, an interior wall;
- a first side wall and a second side wall;
- and wherein the first and second side walls define the associated one of the first and second slots;
- and when the associated one of the first and second inserts is engaged with the male and female end caps, the first end of the body is aligned with the first end of the one of the male and female end caps, the second end of the body is aligned with the second end of the one of the male and female end caps, the exterior wall of the body is aligned with the exterior wall of the one of the male and female end caps, and the first and second sides of the body are in abutting contact with the first and second sides walls, respectively;
- and
- a plurality of ridges and recesses provided on the exterior walls of each of the male and female end caps and the first and second inserts;
- and
- a retaining collar connecting the male end cap to the female end cap.
A device for gripping elongate articles, said device comprising:
- a first end cap;
- a first insert engaged with the first end cap;
- a first channel defined by said first end cap and said first insert, said first channel being disposed along a longitudinal axis of the device;
- a second end cap disposed in end-to-end relationship with the first end cap along the longitudinal axis;
- a second insert engaged with the second end cap;
- a second channel defined by said second end cap and said second insert;
- said second channel being disposed along the longitudinal axis;
- wherein said first and second channels comprise a rope channel adapted to receive the elongate articles therethrough;
- and wherein said first and second channels are longitudinally partially offset relative to each other when the first and second end caps are rotated to a position where they are adapted to secure the rope, wire or cable;
- and
- a retaining collar connecting the first end cap to the second end cap.
The device as defined in clam 10, further comprising:
- a hub which extends longitudinally outwardly beyond the flange at the bottom of the first end cap;
- and
- a counter bore is defined in the second end cap in a position complementary to the hub, and wherein the hub is received in the counter bore when the first and second end caps are placed in end-to-end relationship.
