An adjustable bar-guiding device includes at least one pair of complementarily-shaped jaws which are slideably associated with a fixed frame with the interposition of at least one movement lever mechanism which is actuated by at least one fluid cylinder. The jaws perform a translational motion according to a stroke of mutual approach/spacing apart, between a first configuration of substantial juxtaposition of their respective surfaces and a second configuration in which the surfaces are located at a predefined distance for containing a bar.

A circuit board clamp includes a clamp frame having a first and second frame supports. The clamp frame also includes a top plate arranged between the first and second frame supports. The top plate supports a piston via a threaded fastener engaging a top plate aperture. The piston may be displaced relative to the top plate in accordance with adjustment of the threaded fastener. A pressure plate assembly has a pressure plate and a stem attached to the pressure plate. The stem is positioned within a tubular section of the piston, and the pressure plate is positioned opposite the circuit board from the heat sink. The pressure plate contacts a surface mounted integrated circuit between the circuit board and the pressure plate. A bias member is seated on the bias seat and applies a biasing force on the pressure plate.

A clamping device has a clamping member (2) moveably mounted in a main body 1. A linearly movable actuator (3) is operatively connected to the clamping member (2). A spring element (4) is operatively connected to the actuator (3). A rotatably mounted actuating element (5) is operatively connected to the spring element (4). The spring element (4) is a compression spring that can be compressed when tensioning by the actuating element (5).

A clamping system for a component, especially for an article of footwear or a sports article, may include: (a) a first member; (b) a second member, (c) a pivot about which the first member and the second member are rotatable relative to each other; (d) a first bracket slidably movable along a first path on the first member and a second path, by a first distance, on the second member, when the first member and the second member are rotated relative to each other from a first angle to a second angle; and (e) at least a second bracket slidably movable along a third path on the first member and a fourth path, by a second distance, on the second member, when the first member and the second member are rotated relative to each other from the first angle to the second angle.

Provided is a clamp that can be attached to a tripod or other piece of equipment and which can hold rails for firearms, sights, scopes, parts, and the like, therein. The clamp is self-adjusting due to a compressible cam lever that enables an amount of give or play when clamping onto a rail or other object. The clamp also includes a scroll gear assembly that enables the compressible cam lever to drive opposing jaw plates toward and away from each other thereby clamping and releasing rails and other objects.

The device (1) for restraining/locking mechanical parts on machines tools comprises: a hydraulic cylinder (2); a first piston (9) comprising a head (10) which projects from the hydraulic cylinder (2), the first piston (9) being slidable along a main line (B1); at least two self-centring locking elements (19) joined to the head (10) in such a way that they are movable along lines of sliding (B2) which are substantially transversal to the main line (B1); and movement means (21, 22) for moving the self-centring locking elements (19) between a retracted position and an extracted position, wherein the movement means (21, 22) comprise: a hydraulic chamber (21) made in the first piston (9); a second piston (22) which is slidable along the main line (B1) between a starting position and an arrival position and which comprises an operating portion (23) joined to the self-centring locking elements (19).

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.
