Abstract:
A retaining device for attachment to a screw contains a hollow base element for receiving a clamping part. The hollow base element has a floor having a hole, and an inner surface of the base element on the floor area of the retaining device is implemented as conical to contact the outer surface of the conical body of the clamping part. The clamping part can be moved downward in the direction of the floor by rotating the retaining device around its own axis and biting into a screw which is inserted through the hole and runs through the opening of the clamping part.
Abstract:
A clamping gap nut, comprising: an internal thread (2) about a longitudinal axis (A) of said clamping gap nut; at least two gap ends (3, 4) which face each other tangentially and between them form a gap (5); and at least one tensioning element (10; 10a) connected to each of said gap ends (3, 4), for exerting a force on said gap ends (3, 4) which causes a relative movement of said gap ends (3, 4) in a tangential direction, wherein said at least one tensioning element (10; 10a) is connected, angularly movable, to at least one of said gap ends (3, 4) via a joint which compensates for a change in direction of said force caused by said relative movement of said gap ends (3, 4).
Abstract:
A fastener assembly includes a washer element and a nut element. The nut element is split and includes a screw thread that threadably engages the thread of a bolt or other such fastener element to lock the nut to the bolt. The nut element is adapted by the split to assume an open configuration which permits the nut to move freely along the bolt without being threadably engaged with the bolt and a closed configuration which threadably engages the screw thread of the nut with the screw thread of the bolt. The washer is sized to move freely over the screw thread of the bolt, but to force the nut into the closed configuration when the washer and the nut are cooperatively engaged. The washer maintains the nut in threaded engagement with the bolt when the washer and the nut are cooperatively engaged on the bolt.
