STRAIGHT EDGE CLAMPING DEVICE WITH AN IMPROVED SLIDER
First Claim
1. A straight edge clamping device for clamping workpieces comprising:
- an elongated hollow base having a constant cross-section,the base having a first end, a second end, a flat lower wall for contacting workpieces, an upper wall, and two sidewalls connecting the lower wall and the upper wall;
a first stop fixed at the first end of the base; and
a second stop movably provided along the base, so as to form a clamp for holding the workpieces together with the first stop,wherein the lower wall of the base has an opening, and the opening, the lower wall, the upper wall, and the sidewalls of the base define a channel,wherein the second stop has a body movably received in the channel of the base and a slider that slides in the channel and along the lower wall of the base, contacts the workpiece, and engages with the body in a locking state and disengages from the body in a releasing state, wherein the body has a sliding portion, a handle, an opening, a stop extending horizontally from the sliding portion, a pair of pressing members, and a hole, wherein the slider has a jaw, a rail, a projection, a channel, and a pair of pressing portions having outer surfaces and inner surfaces, wherein in the locking state the pair of pressing members contact with and push the inner surfaces of the pair of pressing portions outwards, so that the outer surfaces of the pair of pressing portions are pushed outwards and contact sidewalls of the recess tightly,wherein the body of the second stop has a shape reverse to the shape of the channel of the base so that the body and the channel interlock,wherein the upper wall of the base has one or more recesses, wherein the width of each of the recesses is smaller than the distance between the two sidewalls by a predetermined distance, and wherein the body of the second stop has one or more projections having a shape reverse to the shape of the recesses so that the recesses and the projections interlock.

Abstract
A straight edge clamping device for clamping workpieces includes an elongated hollow base, and first and second stops. The first stop is fixed at the base, and the second stop is movably provided along the base. The second stop has a body movably received in the channel of the base and a slider that slides in the channel and along the lower wall of the base, contacts the workpiece, and engages with the body in a locking state and disengages from the body in a releasing state. The body has a sliding portion and pressing bumps, and the slider has pressing portions having outer surfaces and inner surfaces. In the locking state the pressing bumps contact with and push the inner surfaces of the pressing portions outwards, so that the outer surfaces of the pair of pressing portions are pushed outwards and contact sidewalls of the recess tightly.
