Abstract

A clamp pin has two clamping jaws, each having a clamping arm and an actuating arm. Being connected pivotably to each other between the clamping and actuating arms, the clamping jaws are pivotable between a condition in which the clamping arms are opened and a condition in which the clamping arms are closed and toward which the clamping jaws are biased. The clamp pin has two actuating links, each having a upper end, which is connected pivotably to the actuating arm of one of the clamping jaws, and each having a lower end. The actuating links are connected pivotably to each other at the lower ends, via a grommet. The clamp pin is useful and may be advantageously combined with a clamp stick having a socket and having a hook movable into and out from the socket, wherein the grommet is adapted to receive the hook and wherein the actuating links are adapted to be drawn into the socket, along with the hook, when the hook is received by the grommet.

Claims

1. A controllable clamp for use by electrical workers, comprising:

a clamping pin having

two clamping jaws, each having a clamping arm and an actuating arm, the clamping jaws being connected pivotably to each other between the clamping and actuating arms and being pivotable between an opened condition, in which the clamping arms are drawn apart from each other and in which the actuating arms are drawn toward each other, and a closed condition, in which the clamping arms are drawn toward each other and in which the actuating arms are drawn apart each other, the clamping jaws being biased toward the closed position, and

two actuating links, each actuating link having an upper end, which is connected pivotably to the actuating arm of a given one of the clamping jaws, each actuating link having a lower end, the actuating links being connected pivotably to each other at the lower ends by a grommet; and

a clamping stick having

a socket, and

a hook removably receivable in said clamping pin grommet and movable into and out from the socket;

wherein said pivotably connected lower ends of said actuating links are receivable in said socket;

wherein said socket is defined by outer sides of said clamping stick; and

said actuating links are movable into said socket by controlled movement of said hook into said socket wherein said clamping jaws are moved toward said open condition by said socket defining outer sides pivotably moving said actuating links together as said grommet moves into said socket.

2. The controllable clamp of claim 1, wherein said socket outer sides are cam surfaces controlling the pivotal position of said actuating links when said actuating links are in said socket.

3. The controllable clamp of claim 1, wherein said actuating links are controllably pivotable between

a first position in said clamping stick socket wherein said actuating links are held between said socket defining outer sides whereby said clamping jaws are in said opened condition, and

a second position in which said actuating links are outside said clamping stick socket whereby said clamping jaws are biased to said closed condition.

4. The controllable clamp of claim 1, whereby in said closed condition said actuating links are pivotably oriented so as to slide along said socket defining side walls and be progressively pivoted together as said actuating links are pulled into said socket.
