摘要

The freewheel system housing (4) and slide rail (5) fit into recesses (7,8) in the door panel (1) or frame (2) and are fixed to a holding plate which in turn is longer than recesses and is screwed at its ends to the door or frame. The lever arm between the frame and panel and between the two recesses (7,8) is covered over to one side by a strip forming one piece with the door panel. The rail should be screwed to the recess floor (8). The door panel has a guide channel for the cable (10) led between housing (4) and wall connection (12).
