Abstract:
An assemblable jerk handle for a lanyard cord including in one embodiment a base portion having a center channel with interior progressive teeth for receiving the lanyard cord and a cap portion for permanently snap-fitting to the base portion to securely grip and therefore retain the lanyard cord within the base portion. In another embodiment, the assemblable jerk handle comprises a base portion having a center channel positioned therethrough for receiving a bifurcated plug that receives the lanyard cord therein and forcibly closes about the Ianyard cord to securely grip and therefore retain the lanyard cord within the base portion.
Abstract:
An embodiment of the present invention is a cable gripping apparatus comprised of a housing with a part conical shaped passageway, two serrated half-jaws, a spacer, a spring, a retaining clip and a cap. The apparatus is spring-loaded and self-locking for gripping and securing a cable. The serrated half-jaws and spring lock the cable in place and only allows the cable to move in one direction. The cap is placed at one end of the apparatus to prevent dirt and moisture from accumulating, thus minimizing the corrosion of the cable.
Abstract:
A rope terminator comprising, an elongate hollow barrel (12) formed from a fibre reinforced synthetic resin material, the barrel having therein a rope receiving passage (13), and said passage having a first end region from which the rope (18) to be terminated extends in use, and an opposite, second end region, the passage tapering in internal diameter from a minimum at said first end region to a maximum at said second end region, a tapering wedge member (14) for insertion into said passage of the barrel to trap fibres (19) of the rope (18) between the outer tapering surface of the wedge member and the inner tapering surface of said passage, said barrel having an outer surface region tapering in diameter. The terminator further includes a hollow outer body member (11) having therein a tapering passage within which said outer tapering surface of said barrel is received, providing a means (15b) of attaching the terminated rope to an anchor point.
Abstract:
Cable support systems (14) for supporting an object at a desired distance below an overhead beam (12) or other structure are provided. Clamps (14) for clamping to the overhead structure are fitted to support cables (34) that encircle objects to be supported by the cable support systems. The clamps have internal methods (34) to support the cables. The cables are then encircled around the objects and fixed relative to the clamp. The distances between the object and the clamps may be precisely controlled.
Abstract:
The invention concerns a connection system (10) between a building work structural cable and a structural element. The system comprises a clamping device (11) linked to the structural element and load transmitting device (12) transmitting clamping efforts to the cable which houses at least a wire (9) of the cable. The wire is bonded in the load transmitting device.
Abstract:
An apparatus having a collet piece (41) in a casing (40) for attaching to a shock cord (43) anywhere along the length of the cord (43). The compression on the cord (43) creates a frictional holding force between the collet piece (41), casing (40), and the shock cord (43). A tapered opening is provided in the casing (40) so that when the cord (43) is pulled in one direction while the casing (40) is held, the frictional force causes the collet piece (41) to slide along the tapered opening thereby reducing the width of the passage through the collet piece (41) and casing (40) to grip and hold the shock cord (43) in the passage. The gripping width automatically follows the decreasing width of the shock cord (43) as it is stretched with increasing force.
Abstract:
The invention relates to locking device for wire and has for a first objective the prevention of accidental release of the wire, and for a second objective, the ability to accommodate several diameters of wire. The first objective is met be a locking device comprising an annular protrusion to one end of the locking device secured to a guideway of the slide, the annular protrusion having an angled exposed end to provide an apex lying above and overlapping the edge of the adjacent slide or push-button and the second objection by a device comprising a body, two channels within the body, entry ends at opposite ends for wires, and wedging means within the body spring-urged towards the entry ends and to protrude into the channels for the purpose of gripping inserted wires and preventing their withdrawal and slides or push-buttons being fitted one within each of the guideways outer end protruding outwards beyond the entry end of the channel allowing inward sliding to push the wedging means against a spring-urge, the slide or push-button and the wedging means being secured together.
Abstract:
A connector or locking device for wires (or wire ropes) W has a body (20) of alloy, two channels (21) within the body, entry ends (23) at opposite ends for wires, and wedges (25) within the body urged by springs (26) towards the entry ends (23) and to protrude into the channels (21) for the purpose of gripping inserted wires and preventing their withdrawal in the opposite direction to insertion, and is characterized in that guideways (30) are formed within the body (20) alongside each channel from adjacent its entry end (23) to beyond its wedge (25), and plastics slide (31) are fitted one within each of the guideways each with its inner end (32) overlapping a nose part (33) of the respective wedge and its outer end (34) protruding outwards beyond the entry end of the channel, retention means (35, 36) being provided between each slide (31) and its guideway (30) while allowing inward sliding to push the wedge (25) against the urge of its spring (26) when the outer end (34) of the slide is pushed relative to the body to release an inserted wire for withdrawal or adjustment of its position relative to the body.
Abstract:
A wire lock includes a body having an opening therethrough, a locking member disposed at least partially within the opening, and a biasing device. The biasing device urges the locking member into a configuration wherein a wire passing through the opening is restrained in at least one direction, and may operate in either tension or compression. The locking member may include one or more locking elements that are compressed about the wire through engagement with a wedge-shaped locking section of the body, with the biasing member urging the locking member against the locking section. In other embodiments, the locking member is a locking pin riding on an inclined surface of an elongate slot extending across the body, with the biasing member urging the locking pin against one end of the slot, and the wire pinched between the pin and a body surface opposite the inclined surface.
