Abstract
A clamp has a housing with a piston assembly positioned in the housing. A piston rod lock assembly is coupled with the piston rod and is positioned in the housing. A clamping arm is coupled with the piston rod and moves from a position parallel to the piston rod, when in an unclamped position, to a position substantially perpendicular to the piston rod, when in a clamping position.
Claims17
A clamp comprising:
- a housing;
- a piston assembly in the housing, the piston assembly including a piston rod moving between a first and second position;
- a piston rod lock assembly directly coupled with and surrounding the pistol rod for locking the piston rod in any locked position when the piston rod lock assembly is engaged, the piston rod lock assembly positioned in the housing;
- and
- an arm coupled with the piston rod, the arm moving in and out of the housing between a clamped and an unclamped position so that an arm axis is substantially aligned with a piston rod axis.

A clamp comprising:
- a housing;
- a piston assembly in the housing, the piston assembly including a piston rod moving between a first and a second position;
- a piston rod lock assembly surrounding the piston rod, the piston rod lock assembly directly contacting the piston rod for locking it in position;
- an arm coupled with the piston rod, the arm moving between a clamped and an unclamped position;
- and
- the arm defines a longitudinal axis and the longitudinal axis moving from a position parallel to the piston rod inside the housing, when the arm is in the unclamped position, to a position substantially perpendicular to the piston rod outside the housing, when the arm is in the clamped position.

A clamp comprising:
- a housing;
- a piston assembly in the housing, the piston assembly including a piston rod moving between a first and a second position;
- an arm coupled with the piston rod, the arm moving between a clamped and an unclamped position;
- the arm defines a longitudinal axis and the longitudinal axis moving from a position parallel to the piston rod, when in the unclamped position, to a position substantially perpendicular to the piston rod, when in the clamped position;
- and
- a non-toggle mechanism for locking the piston rod wherein the non-toggle mechanism is coupled with the piston rod and is engageable along the piston rod at any position along the piston rod for locking the piston rod when the non-toggle mechanism is engaged so that an angular orientation of the non-toggle mechanism with respect to the piston rod is a same in both an unlocked and locked position.
