  • Patent number: 6158729
    Abstract: The present invention provides a clamp that is compact and lightweight, yet provides high holding strength and stiffness or rigidity. The clamp uses a unique double slant interface design which provides mechanical advantages to resist forces applied to the clamp members as the load increases. The clamp allows for rapid and remote-activated release of the clamp jaws by applying only a small operating force to an over-center lock/release mechanism, such as by pulling a manual tether.

  • Patent number: 6149146
    Abstract: A system and method for securely clamping a target material that is to be manipulated using conventional machining techniques. The vise includes a single piece that includes a rigid jaw and a floating jaw that are integrally connected. The floating jaw is formed by a vertical and horizontal cut through a portion of the vise to enable the floating jaw to bend slightly in a hinge-like manner. A top portion of the rigid jaw and a top portion of the floating jaw are cut in a first pattern to form a working area. The size of the first pattern is approximately equal to the clamping surface of the target material. The size of the working area can be adjusted by securing devices that can expand the width of the working area to receive the target material and that can reduce the working area to securely clamp the target material. Additional cuts can be made in the vise to accommodate multiple target materials that can be secured independently.

  • Patent number: 6116588
    Abstract: A clamping device includes a clamp arm (2), an operating lever (3) for pivotally operating the clamp arm (2), and a toggle mechanism (T) provided in connection with the operating lever (3). The clamp arm (2) is formed with a guide path (2a) that intersects a direction in which the clamp arm (2) pivots so that an output member (9) of the toggle mechanism (T) is guided along the guide path (2a). Accordingly, workpieces (W) of heights that can vary over a wide range of up to several centimeters can be firmly fixed without the necessity of performing a troublesome adjustment operation.

  • Patent number: 5961109
    Abstract: The clamp is a locked over-center toggle clamp having a toggle lever that actuates a clamp arm between clamped and released positions. An amplification lever is secured to a cam pivot for rotation of the cam pivot inside a base. One end of the clamp arm is pivoted to the cam pivot to act as a follower so that rotation of the cam pivot cams the clamp arm to amplify the hold-down force of the toggle clamp.
