Wedge and socket assembly
View Patent ↗A socket and wedge assembly that securely holds wire rope and is easy to release includes a collapsible wedge. The wedge collapses at the front, narrowed end to utilize the high pressures at the front end of the wedge in effecting the collapse and releasing the rope. The wedge includes a movable element that pivots and/or translates to facilitate a quick and reliable collapse of the wedge and release of the wire rope. The wedge includes a cavity to at least partially exhaust the fumes created from cutting the support with a torch for release of the wire rope.
1. A collapsible wedge for holding a wire rope within a socket, the wedge comprising (i) a base, (ii) an arm coupled to the base, the base and the arm collectively defining a narrow front end, a wide rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, and (iii) a removable support proximate the front end which maintains the arm in a spaced position relative to the base to secure the wire rope in the socket when in use and which when removed permits movement of the arm toward the base to reduce the width of the wedge and permit release of the wire rope, wherein the base includes a brace that projects outward to overlap and abut a front end of the arm to restrict forward movement of the arm while securing the wire rope.
2. A collapsible wedge in accordance with claim 1 wherein the arm pivots relative to the base when the support is removed.
3. A collapsible wedge in accordance with claim 2 wherein the arm translates toward the base when the support is removed.
4. A collapsible wedge in accordance with claim 1 wherein the arm translates toward the base when the support is removed.
5. A collapsible wedge in accordance with claim 1 wherein the support is integral with the arm.
6. A collapsible wedge in accordance with claim 1 further including a cavity between the arm and the base which exists before and after collapse of the wedge and is able to exhaust fumes from a torch cutting the support.
7. A collapsible wedge in accordance with claim 1 wherein the arm is smaller than the base.
8. A collapsible wedge in accordance with claim 7 wherein the arm is less than about half of the overall length of the wedge.
9. A collapsible wedge for holding a wire rope within a socket, the wedge comprising two components including an arm and a base, a pivot pin coupling the two components together with the arm being shorter than the base, and a removable support collectively defining a narrowed front end, an expanded rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, wherein removal of the support causes the wedge to collapse at the front end to release the wire rope from within the socket.
10. A collapsible wedge in accordance with claim 9 wherein the support is integral with one of the components.
11. A collapsible wedge for holding a wire rope within a socket, the wedge comprising (i) a base, (ii) an arm pivotally coupled to the base, the arm being smaller than the base and extending substantially less than the length of the diverging sides, the base and the arm collectively defining a narrowed front end, an expanded rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, and (iii) a removable support which maintains the arm in a spaced position relative to the base to secure the wire rope in the socket when in use and which when removed permits pivoting of the arm toward the wedge to reduce the width of the wedge and permit release of the wire rope from within the socket.
12. A collapsible wedge in accordance with claim 11 wherein the support is proximate the front end and the arm pivots toward a front end of the base.
13. A collapsible wedge in accordance with claim 9 wherein the shorter component is less than about half of the overall length of the wedge.
14. A collapsible wedge in accordance with claim 11 wherein the shorter component is less than about half of the overall length of the wedge.
15. A wedge and socket assembly for holding a wire rope comprising:
a socket defining a narrowing cavity; and
a collapsible wedge for holding a wire rope within the socket, the wedge including (i) a base, (ii) an arm coupled to the base, the base and the arm collectively defining a narrow front end, a wide rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, and (iii) a removable support proximate the front end which maintains the arm in a spaced position relative to the base to secure the wire rope in the socket when in use and which when removed permits movement of the arm toward the wedge to reduce the width of the wedge and permit release of the wire rope, wherein the base includes a brace that projects outward to overlap and abut a front end of the arm to restrict forward movement of the arm while securing the wire rope from within the socket.
16. A wedge and socket assembly for holding a wire rope comprising:
a socket defining a narrowing cavity; and
a collapsible wedge for holding a wire rope within the socket, the wedge including two components including an arm and a base, a pivot pin coupling the two components together with the arm being shorter than the base, and a removable support collectively defining a narrowed front end, an expanded rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, wherein removal of the support causes the wedge to collapse at the front end to release the wire rope from within the socket.
17. A wedge and socket assembly for holding a wire rope comprising:
a socket defining a narrowing cavity; and
a collapsible wedge for holding a wire rope within the socket, the wedge comprising (i) a base, (ii) an arm pivotally coupled to the base, the arm being smaller than the base and extending substantially less than the length of the diverging sides, the base and the arm collectively defining a narrowed front end, an expanded rear end, rearwardly diverging sides extending between the front and rear ends, and an external channel along the sides and rear end in which is received the wire rope to be secured in the socket, and (iii) a removable support which maintains the arm in a spaced position relative to the base to secure the wire rope in the socket when in use and which when removed permits pivoting of the arm toward the wedge to reduce the width of the wedge and permit release of the wire rope from within the socket.
