<p>The driver (1) is arranged between two ends of a traction device (6) e.g. a toothed belt, driven around guide elements (4,4'). The drive member, in operation, causes linear movement of the driver (1) in the longitudinal direction of the housing (12). The two ends (15,15') of the traction device are fastened to the drive member (16) by respective connector devices (32). The drive member (16) is formed as a tension lock for the traction device (6). It is divided into two locking elements (28,28') each allocated to an end of the traction device. The locking elements are fixed relative to each other in a locking position corresponding to a desired tension. The locking elements (28,28') each have a guide section (33) running inside a longitudinally open recess (23) in the housing (12). The guide sections are connected via the connection devices (32) to respective ends of the traction device. The locking elements also each have a locking section (36,36') outside the recess (23). At least the locking sections of the locking elements overlap in the longitudinal direction. The locking elements (28,28') are coupled together for longitudinal displacement for continual adjustment of the tension via longitudinal guides. The locking elements can be fixed relative to each other to fix the locking position at the overlapping parts of the locking sections.</p> |
