The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The straight edge clamp body includes at least two sections that are hinged together to allow the sections to be folded upon one another when not in use and unfolded when in use.

The present invention relates to a straight edge clamp that has a clamping head assembly and a stop assembly mounted upon the body of the straight edge. The head and stop are not connected together and the stop assembly is free to move with respect to the head assembly. The stop assembly has a locking assembly that allows it to be locked to the straight edge. The straight edge clamp body can include sections that are adapted to be connected together to form the overall length of the straight edge clamp.

This disclosure generally pertains to various accessories for use with bar clamps to enhance the capabilities and functionality of the bar clamps. The accessories described in detail herein include removable and replaceable bar clamp attachments, bar extenders, and stability stands for use with a bar clamp.

A support for a mitre joint uses two wedging mechanisms disposed at a characteristic angle. Each wedging mechanism is arranged to locate inside a hollow rail, such as within an extruded hollow beam. The wedging mechanism can be operated from outside the joint in order to clamp the mechanism in position. The mechanism has a self centering capability to assist in accurately locating the rails relative to each other.

A device for displacing a push/pull rod in steps includes a housing and a drive lever that is supported by the housing and displaces a drive element, which engages on the push/pull rod, forward in a clamping direction relative to the housing during an advancing actuation. A blocking element is supported by the housing and prevents a reverse displacement of the push/pull rod in a release direction opposite the clamping direction in a blocking position and which can be displaced from the blocking position into a release position by actuating a release lever that engages on the blocking element. A movement limiting element is struck by the blocking element during a forward displacement of the drive element, the forward displacement carrying the push/pull rod. The movement limiting element is acted upon by a spring element against the blocking element and is arranged in a pocket of the release lever.

Provided is a compressible cam lever that has a section that can be compressed by external force. When the external force is released, elastic force within the cam lever causes the section to return back to its original position creating a spring force. The compressible cam lever may be used as part of a handle for opening and closing a clamp that is part of a tripod or other piece of equipment which can hold rails for firearms, sights, scopes, parts, and the like, therein. The compressible cam lever may include a handle, a round-shaped section comprising a flexible curved surface that curves back towards the handle and protrudes outward, and an opening disposed between an end of the flexible curved surface and the handle.

A dual-cam device is described configured to be engaged with a rail and a stopper for clamping at least one object. The dual cam device comprises a jaw; a body; a member connecting the jaw and the body wherein the member has a member-base configured to associate with and slide on the rail; and a lever pivotally connected to the member, wherein the lever has a first cam and a second cam and wherein the lever is configured to be tilted from an open position to a clamp position and vice versa. During tilting the lever from an open position to a clamp position in which the object is clamped, the first cam causes the dual cam device to secure emplacement position of the dual cam device to the rail and then the second cam causes the dual cam device to press and clamp the object by the jaw against the stopper. It is further described a clamping apparatus that comprises at least one dual cam device; at least one rail having a channel; and at least one stopper.
