Abstract

A toggle clamp has a base with a support portion and a securement portion. A handle mechanism is connected to the base support portion. A clamping arm is movably supported by a pivot pin on the base support portion. The clamping arm is coupled with the handle mechanism. The clamping arm includes a clamping element that moves transverse to the workpiece. The handle is moved between a first and second position. The clamp arm pivots about the pivot pin on the base until reaching a stop position. The handle continues to a clamping second position as the clamping element moves linearly transverse toward the workpiece into a clamped position.

Claims (10)

1. A toggle clamp for providing travel of a clamping element in a direction transverse to a workpiece of a clamp arm comprising:

a base having a support portion and a securement portion;

a handle mechanism connected to the base support portion;

a clamping arm movably supported by a pivot pin on the support portion of the base, the clamping arm coupled with the handle mechanism, the clamping arm coupled with the clamping element, the clamping element movable along an axis perpendicular to the workpiece, wherein as the handle mechanism is moved between a first and second position, the clamping arm pivots about the pivot pin on the base support portion until reaching a stop position stopping movement of the clamping arm, the handle mechanism continues to the second position, as this occurs, the handle mechanism moves the the clamping element so that the clamping element moves independently, with respect to the clamping arm in its stopped position so that the clamping element moves linearly along the axis perpendicular to the workpiece into a clamped position.

2. The toggle clamp of claim 1 , further comprising a clamp plate and a support for the clamping element.

3. The toggle clamp of claim 2 , wherein the clamp plate contacts the clamping element for moving the clamping element along the axis perpendicular to the workpiece.

4. The toggle clamp of claim 1 , wherein the clamping element includes a plunger, a helical spring surrounding the plunger, a stationary plunger block receiving the plunger and a workpiece contact stopper movably coupled with the plunger.

5. The toggle clamp of claim 4 , further comprising a support member coupled with the base and the plunger block.

6. The toggle clamp of claim 1 , further comprising a linkage between the handle mechanism and the base for locking the handle mechanism in the second position.

7. The toggle clamp of claim 1 , further comprising a pair of bushing contacted by the clamping arm in the stopped position.
