US 2004/0200306 A1 · Safety device for locking an adjustable connecting piece

Abstract

At least one first mounting part (1), which has at least one passage opening (1a) for guiding a connector (3). The connector connects to one another at least two clamping parts (4, 7) that are movable in relation to one another, which clamp the connecting piece (2). The connector (3) and the clamping parts (4, 7) form a first clamping mechanism. Structure is provided for securing the first clamping mechanism, and includes a second clamping mechanism (10, 11), which is located between the clamping parts (4, 7) of the first clamping mechanism and is coupled with same. The second clamping mechanism has at least one second mounting part (1), which has a passage opening (11a) that is at least congruent with the passage opening (1a) of the first mounting part (1), as well as a spindle (10), which is connected with the first clamping mechanism (3, 4, 7) via a clamping part (4) of the first clamping mechanism (3, 4, 7). The clamping part (4) is designed as a spindle nut, so that the two clamping mechanisms (3, 4, 7; 10, 11) can be released or locked via the first clamping mechanism (3, 4, 7).
