A piston rod-less linear drive () has a housing () with a longitudinal slot () having a moving force coupling member extending through it. The outer slot opening () is provided with at least one covering band (), which is fixed at an attachment section () on a longitudinal side () of the outer slot opening (). The covering band ( )) furthermore has a pivoting covering section (), which is provided with detent means (), which render possible a releasable detent function in a covering position covering the outer slot opening. Actuating means kinematically coupled with the force coupling member may act on the covering band in order to cause the detent locking action.

Linear drive with no connecting rod

A piston rod-less linear drive having a drive part adapted for motion in the longitudinal direction of the housing, such drive part being kinematically coupled by way of an entraining member running in a longitudinal slot in the housing with a guide slide arranged externally on the housing for sliding movement. For the connection between the entraining member and the guide slide a force transmitting part is provided which has a coupling socket in which the entraining member interlockingly fits by means of a coupling section in the longitudinal direction of the housing.

Piston rod-less linear drive

A piston-rod-less linear drive ( ) whose housing ( ) possesses a tube body ( ) with housing covers ( ) mounted at terminal sides. The tube body ( ) is provided with a longitudinal slot ( ) which is covered over by an internal and/or outer closure band ( and ). For securing the terminal band sections ( and ) and securing means ( ) are provided, which comprises a support body ( ) arranged on the respective terminal band section ( and ), such support body ( ) projecting laterally past the outline of the closure bands ( and ) and bearing independently from the housing cover ( ), provided on the same terminal side, on the associated terminal face ( ) of the tube body ( ).
