Abstract: The present invention will provide a device in which the gripping action is achieved by a compliant membrane manipulated by electromagnetic forces. The gripping force provided by the present invention is best suited for delicate objects, as it gently applies the gripping force necessary for displacement. This is accomplished through a chamber, a membrane, a plunger attached to the membrane, and a solenoid configured to manipulate the plunger, and thus, the membrane.

Abstract: The present invention provides improved methods and apparatus for securely gripping objects or panels having cross sections, including heavy objects such as granite slabs to be used as counter tops, or lighter objects such as doors or windows, in order to facilitate lifting, moving, transporting, installing and/or storage thereof. A pair of jaws are provided between a rotatable turnbuckle and ratchet assembly which opens or closes the jaws around an object. The ratchet may be used to impart fine rotation to the turnbuckle in one direction to apply pressure to the jaws to firmly engage an object. Reversing the ratchet and rotating the turnbuckle in an opposite direction allows the object to be released. A handle on the ratchet facilitates lifting and moving the object gripped between the jaws.

Abstract: A workpiece supply-and-discharge device includes a fixed portion, and a swivel portion that swivels on a bed. The fixed portion is provided with a plurality of fixed rails having an arc shape and separated from each other. Movable rails enter or exit from gaps left between the fixed rails as reciprocating actuators operate. Workpiece gripping portions configured to grip a workpiece are provided with sliders. When the workpiece gripping portions carry the workpieces while swiveling integrally with the swivel portion, the sliders transfer from the movable rails to the fixed rails or from the fixed rails to the movable rails.

Abstract: A foldable elongate grabber tool includes a proximal section and a distal section that are foldable relative to each other between a folded position and an extended position. An actuation member is attached to the proximal section and actuates a cable coupled to engagement elements disposed at the distal section. A hinge mechanism connects the proximal and distal sections. The hinge mechanism automatically locks the proximal and distal sections relative to each other when they reach the extended position. The proximal and distal sections are biased to open automatically from the folded position to the extended position. A hinge pin is biased toward a locked position, and is blocked from moving to the locked position until the proximal and distal sections reach the extended position.

Abstract: A gripping device has at least one tendon associated with a gripping arm and guided in a freely slidable manner along a first and second arm portion thereof through a succession of guiding elements. The guiding elements associated with a first proximal arm portion of the arms are carried by an inner yielding panel so that when the inner yielding panel on the inner side of the first proximal arm portion engages against an item or component to be gripped, the guiding elements of the tendon carried by the inner yielding panel cause a tensioning of the tendon, which results in an articulation and/or inflection movement of a second distal arm portion with respect to the first proximal arm portion.

Abstract: An apparatus includes a bellows and a lip. The bellows defines an interior cavity. The lip is coupled to the bellows such that the lip is concentric with the bellows. The lip extends away from the bellows in a radial direction and in a vertical direction such that the lip forms a cup shape. The bellows and the lip define a passage from the lip through the interior cavity. The lip includes a rib on an outer surface of the lip such that the rib extends along the outer surface of the lip and away from the bellows in the radial direction and in the vertical direction.

Abstract: A lifting apparatus clamps around the sides of a gang box to facilitate lifting and transporting the gang box. The lifting apparatus has a pair of lifting brackets a set of mounting points and a lateral clamp. The mounting points are support protrusions that extend from the lifting brackets to facilitate affixing the lifting apparatus to the bang box. The lateral clamp is connected in between the brackets and provides the force required to clamp the lifting apparatus around the gang box. Thus preventing the lifting brackets from becoming dislodged from the gang box.

Abstract: Systems and methods to grasp objects using vacuum-actuated end of arm tools may include extending pistons and suction cups. For example, responsive to application of negative pressure, a piston may move from a retracted position to an extended position. In addition, responsive to grasping an object by a suction cup, the piston may remain in the extended position due to continued generation of pressure differentials that apply forces to the piston toward the extended position. Alternatively, a piston may be biased toward an extended position due to a spring force, and may remain in the extended position responsive to grasping an object. In the extended position of the piston, an object may be grasped with an amount of passive compliance to external forces that may be applied to the object.
