A holding structure, such as a manipulator, includes a plurality fingers. At least one of the fingers is movable such that an object can be held or released by a closing or opening motion of the movable finger. At least one contact surface of the fingers, which is capable of being brought into contact with the object, is formed by an elastic member, and at least one elastic member is adapted to reversibly change its elasticity under the control of an external supply of energy to the elastic memb...

A device for holding a rotary element stationary relative to a fixed body, the device comprising at least one element, adapted to engage with the rotary element to hold the device in a fixed position relative to the rotary element; and an engaging member, adapted to engage with the body to hold the device relative to the body.

A device (10), which is for holding a transport unit (W) that moves in a transport direction (T), includes an actuator (16) equipped with a drive unit (16c/16d) and an actuating element (16a), which, in an extended position, can be brought directly or indirectly into a holding engagement with the transport unit (W); a sensor unit (22) that is situated before the actuator (16) and a sensor unit (24) that is situated after the actuator (16), both of which are for detecting the presence of a transp...

The invention relates to a holding device, preferably a shell device, which comprises a magnet that can be transferred from a locking position, in which the magnet is preferably operatively connected to a magnetizable shell support so as to magnetically act upon it, to a detach position in which the magnet is spaced apart from the shell support. The aim of the invention is to simplify a holding device of the above-described kind. The magnet, for the purpose of transferring it from the locking po...

A holding device for at least one object carrier, the object carrier being suitable to receive one or more organic and/or inorganic samples and comprising materials such as glass, plastic, silicon, pyrolytic graphite, and/or metal, this holding device being configured to be gripped by grippers of a robot. The holding device comprising two essentially parallel lengthwise walls and two essentially parallel transverse walls which extend substantially at right angles from the lengthwise walls. Holdi...

A holding apparatus provided with a holding portion for holding a flange portion of an optical element. The holding portion includes a bearing surface block having a bearing surface, which contacts the flange portion, and a bearing surface block support mechanism, which rotatably supports the bearing surface block about a tangential axis of the optical element. This structure holds the optical element with the optical element holding apparatus in a kinematical manner and maintains satisfactory i...

A holding device for a vacuum unit has a lifting table transferable between a lower end position and an upper end position for moving a support plate toward the underside of a disc-shaped workpiece. The workpiece is supported by a support ring carrying centring pins spaced to form an equilateral triangle, in the center of which the axis of the support plate is located. A clamping ring clamps the workpiece with the support ring. The centring pins engage the clamping ring to center the support rin...

There is disclosed a holding device for holding two rotary members relative to one another. The device has two holding members and a connecting member to which the holding members may be clamped by respective clamps. One of the holding members may be selectively positioned along the connecting member and clamped thereto at selected distances from the other holding member.

A holding clip for tubes, hoses and the like has a pocket and deflectable arms protecting an entrance to the pocket. The arms extend one past another and interdigitate one with another. The arms deflect outwardly in response to force exerted thereagainst from outside of the pocket and interengage one against another to resist force exerted thereagainst from within the pocket.

To enable heavy workpieces to be orientated into any desired position without re-clamping, more particularly for welding seams horizontally from above, as is most favorable, a clamping plate or table (3) is pivoted for unrestricted rotation about an axis (5) at the free end of a cantilever arm (2) supported from a stand (1) for rotation about a horizontal axis (13) by flange elements (14, 15) which are adjustable with respect to one another in two directions at right angles to balance a workpiec...
