Abstract: A system and method which provide a gripping mechanism and a complementary “handle,” which enable a microcomponent to be grasped with the gripping mechanism are disclosed. A preferred embodiment provides a gripper and a complementary handle, which is implemented on a microcomponent to be grasped, to enable the gripper to effectively grasp the microcomponent by grasping the complementary handle implemented for such component. A preferred embodiment provides a gripper and a complementary handle that is implemented on a microcomponent to enable the microcomponent to be accurately picked-and-placed with the gripper. The complementary handle may be an integrated part of the microcomponent to be grasped, or the handle may be a separate component that is capable of being permanently or temporarily coupled to a microcomponent. Most preferably, the gripper and complementary handle may be implemented to constrain all six degrees of freedom, both translational and rotational, of a grasped handle relative to the gripper.

Abstract: A load lifting apparatus suitable for use in a materials-handling operation, which enables loads of various shapes and structures, e.g. concrete products, to be clamped by a one-touch simple operation despite an extremely simple structure and allows the loads to be released by a one-touch simple operation at desired places after they have been lifted and moved thereto. The apparatus includes a link mechanism (14) in which a pair of clamping members (1 and 2) and a plurality of members (4, 5, 8, 8-1, 8-2) are supported by a plurality of pivot shafts. The upper part of the link mechanism (14) is arranged to be capable of being lifted and lowered by a lifting device. The clamping members (1 and 2) rotate about a pivot shaft (3 or 3′) in response to vertical extension and contraction of the link mechanism (14), thereby enabling an object (11) to be grasped by the distal end portions of the clamping members (1 and 2) directly or indirectly through grab members (10) by the extension of the link mechanism (14), and allowing the object (11) to be released therefrom by the contraction of the link mechanism (14). The apparatus has a lock-unlock mechanism (20, 30, 40, 50, 60, or 70) actuated in response to the vertical extension and contraction of the link mechanism (14), caused by vertical movement of the lifting device, to lock the clamping members in respective predetermined positions of rotation about the pivot shaft and to unlock the clamping members in response to the vertical movement of the lifting device.

Abstract: A damped mechanical joint assembly comprises two damping members, a joint body positioned therebetween and rotatable relative thereto; and a retainer for maintaining engagement of the damping members with opposite damping surfaces of the joint body. The joint body is provided with a plurality of damping cylinders positioned around the joint rotation axis in a uniformly angularly spaced circular pattern, and each damping cylinder comprises a pair of piston chambers, each opening onto opposite damping surfaces, and a constricted passage connecting the piston chambers. Each of the piston chambers is provided with a piston assembly slidably positioned therein, and each damping cylinder is filled with fluid between the piston assemblies. Each damping member is provided with a circular groove comprising a plurality of uniformly angularly spaced ramped depressions separated by groove barriers. The number of damping cylinders preferably differs from the number of depressions by at least two. The fluid in the damping cylinders urges each piston assembly into engagement with the groove of the corresponding damping member, and the damping members are positioned so that when a piston assembly is located within a ramped depression of the groove of one damping member, the corresponding piston assembly is located at a groove barrier of the groove of the other damping member, thereby resulting in reciprocating motion of the piston assemblies and concomitant flow of the fluid though the constricted passage of the damping cylinders as the joint body rotates relative to the damping members. Viscous resistance to flow of the fluid through the constricted passage as the joint body rotates causes the piston assembly to be urged more strongly into engagement with one of the ramped depressions, thereby producing a damping torque opposing rotation of the joint body, the damping torque increasing with increasing angular velocity of the joint body.

Abstract: A device and method for gripping a handrail or other object having a top and a bottom surface. The device includes a handle for gripping by a user. A fixed member is coupled to the handle for engaging one of the top and bottom surfaces of the handrail, and a movable member is movably coupled to the handle for engaging the other of the top and bottom surfaces of the handrail. An actuator coupled to the handle controls the movement of the movable member, the actuator allowing for repositioning and locking of the device with respect to the handrail. When the device is locked with respect to the handrail the fixed member and movable member engage the top and bottom surfaces of the handrail such that a force tangential to the handrail can be applied to the handle without the device sliding on the handrail.

Abstract: A grapple 1 comprises a sleeve 8 moveable along a shaft 12. The sleeve 7 is joined to an upper attachment 6 for receiving the long-line of a crane, and the shaft 12 is joined to a pivot attachment 13. The sleeve 7 and the pivot attachment 13 are joined to jaws 2 and 3 which can move in a scissor-like fashion. Pushing down on the sleeve 7 causes a rider 9, forming part of a catch rod 8, to move into a series of stepped channels in a block 14 associated with the shaft 12. The rider 9 can be positioned in the channels to lock the jaws 2 and 3 open, and can be subsequently removed from the channels to enable the jaws 2 and 3 to close towards one another.

Abstract: A machine for lifting and moving heavy slabs includes two channels connected only by a cable. The channels are placed against opposite edges of a slab. Each channel has a lower flange which is beveled so that the flange will scoop under the edge of the slab when moved toward the opposing channel. The channels are moved by attaching the cable to one channel and pulling the cable upward from the sheave on the other channel. Further lifting of the cable lifts the channels and the slab for moving.

Abstract: Lifting tools for safe, 105 degree, off-center rotation of large, heavy objects are disclosed. A lifting tool includes a bar that can be positioned generally parallel to a centerline of the object, and first and second clamps that are rotatably or slidably coupled to first and second ends of the bar, respectively. The clamps are adapted to secure the tool to edges of the object. The tool also includes a pivot arm that is rotatably coupled to the bar, which allows the object to be lifted, rotated up to 90 degrees, moved, and then set down. The pivot arm includes first and second chain sprockets disposed along a length thereof. A second pair of chain sprockets is coupled to the second chain sprocket via a common shaft. A pair of chain segments are attached to the pivot arm, and engage each of the second pair of chain sprockets. A first end of the pivot arm can be coupled to a hoist hook, for example, via a chain that engages the first and second chain sprockets, and is coupled to the bar at a point between the clamps.
