Abstract: A mechanism system can include a load responsive component, a pivot point coupled to the load responsive component, and a mechanism, coupled to the load responsive component, configured to engage when the load responsive component moves and configured to induce a first ratio of movement and a second ratio of movement.

Abstract: A handle for a surgical instrument used in keyhole, endoscopic, and laparoscopic surgery, having a pivoting or articulated end portion and a mechanism for indexing the pivoting movement of the end portion. The indexing mechanism allows adjustment of the angle of the end portion for improved control and tactile feedback to the user. The handle also has a mechanism for locking and unlocking movement of the end portion whereby the end portion can be pivoted or articulated to a desired angle and the locking mechanism moved to a position to prevent movement of the end portion, thus holding it at the desired angle to achieve the improved control and tactile feedback to the user.

Abstract: A hinge assembly includes a hinge and a detent cover. The hinge pivotally connects a first acting member to a second acting member. The detent cover can cover the hinge to stop the rotational motion between the first acting member and the second acting member.

Abstract: Pliers for crimping work pieces include a pliers head, a first pivot jaw (4) and a second pivot jaw (3). A common joint (5) pivotally connects the first and second pivot jaw (4, 3). Two dies together form a crimping die (8). A first handle (2) is connected to the first pivot jaw (4). The first handle (2) is divided into at least a first portion (21) and a second portion (22). The first portion (21) is designed as a plate. A second handle (1) is connected to the second pivot jaw (3). The first handle (2) and the second handle (1) are movable with respect to one another and operable to crimp the work piece in a few crimping steps. A locking mechanism (28) includes a tooth segment (29), and it serves to attain a defined closed position of the dies. The tooth segment (29) is designed as one piece with the first portion (21). A stop mechanism (31) includes at least two stops, and it connects the first portion (21) and the second portion (22) in a plurality of different angle positions.

Abstract: A pair of manual tongs comprising two limbs which are rotatably connected in a common first rotational axis. The first limb is separated into two levers in its lever section, the two levers being rotatably connected in a first articulation, in a second rotational axis parallel to the common first rotational axis. A means of traction connects the second limb to the lever of the first limb, which is situated at a distance from the handle. The means of traction can be shortened by means of a pivotal movement of the lever of the first limb, which is situated close to the handle, above the second rotational axis. The areas of use of the manual tongs are often difficult to access. According to the invention, the second limb of the inventive manual tongs is thus separated into a lever situated at a distance from the handle and a lever situated close to the handle and the two levers are rotatably connected in a second articulation, in a third rotational axis which is parallel to the common first rotational axis.

Abstract: The device has affair of handles each coupled to a tong, which are movable to clamp or release the target. A ratchet mechanism couples to a handle to re-vector the handle in order to reduce the operational footprint of the device to accommodate obstacles and operate successfully in confined and limited access spaces. Operation of the apparatus allows the action to be accomplished over a variable number of strokes, with the distance of each stroke, and thus the arc of the handles traversed, varying with each stroke, while still accomplishing the desired action.

Abstract: Pliers for crimping work pieces include a pliers head and two pivot jaws (3, 4) being arranged in the region of the pliers head. A common joint (5) pivotally connects the two pivot jaws (3, 4). Two dies forming a crimping die (8) for crimping the work piece are arranged at the two pivot jaws (3, 4). Two handles (1, 2) are connected to the pivot jaws (3, 4), and they each include an end portion (20, 23) facing away from the pliers head. At least one of the handles (1, 2) is divided into at least two portions (21, 22). The handles (1, 2) are designed and arranged to be movable with respect to one another and to be operable to crimp the work piece in a few crimping steps. One portion (22) of the divided handle (1, 2) is coupled to the other portion (21) in a plurality of different angle positions each corresponding to one crimping step in a way that the end portions (20, 23) may be held and operated by the fingers of one hand of the operator in each angle position of each crimping step.

Abstract: A pliers having separate jaws secured to handles by interengagement of either a press-fitted boss and corresponding smooth bore or a threaded boss and threaded bore between the jaws and handles. In at least round nose and needle nose embodiments each jaw has a generally symmetric envelope about a central axis and the threaded member is located concentric to the central axis for ease and economy of manufacture. The long nose embodiment may also utilize the symmetric envelope with a portion of the generally conical jaw removed to form a flat, work engaging surface. Mating surfaces perpendicular to the central axis maintain alignment of the jaw to its respective handle. Round nose, long nose and needle nose pliers may be manufactured using the present invention.

Abstract: Pliers for use in a narrow space, including: a pair of neck sections which are pivotally connected with each other by a shaft rod and can be opened and closed; a pair of jaw sections located on one end of the neck sections in the same direction to define a pliers mouth; and two grips disposed at the other ends of the neck sections for a user's hands to hold and control the jaw sections to open or close. At least one of the grips is pivotally connected with a corresponding neck section, whereby the grip can be rotated about an axis parallel to a longitudinal direction of the pliers into different operation aspects and adapted to different operation sites.

Abstract: Pinch free gripping pliers are described including first and second pivoted legs joined by a pivot bolt. The pivot bolt is mounted to the first leg and is slidably received in an elongated slot in the second leg, thereby enabling the pliers to have multiple jaw opening ranges. An arcuate rib on the shank of one leg engages and meshes with any selected one of several arcuate grooves formed in the second leg, thereby maintaining the setting of the pivot bolt. An overtravel stop member is located on the first leg, facing an edge surface on the second leg that is acutely angled relative to the slot. The overtravel stop member and edge surface engage as the handles of the pliers close, limiting further closing and preventing the handles from coming together closer than a predetermined safety distance. The predetermined safety distance is the same at each of the multiple jaw opening ranges, by provision of the angled edge surface.

Abstract: A gripping tool acting as both a pair of pliers and a wrench self locks and self releases upon application or removal of gripping pressure, respectively.

Abstract: A readjustable pair of pliers for mounting circlips has a handle which with the aid of a sidewardly bent attachment part is pivotally connected to an intermediate member carrying a jaw with an engagement pin. A second jaw carrying an engagement pin is rigidly connected with a second handle defining therewith a rigid unit to which said intermediate member is pivotally attached. The attachment part is defined by a parallelepipedic block tightly fitting in a corresponding groove in the intermediate member. By swinging the second handle through 180.degree. relative the intermediate member the mode of operation of the pair of pliers is altered in dependence on if a circlip for inner or for outer mounting has to be served.

Abstract: A mechanism for use in crimping and cutting tools and the like includes a resettable drive system which permits the user to selectively increase or decrease the angular opening between the tool handles at any fixed point in the operative stroke of the tool. The handles of the tool may thus be disposed at any desired angular relationship with respect to one another for operation either in close quarters or for more comfortable operation without sacrificing the lever advantage originally designed into the tool.
