<p>Guide-rails, adjoining the lock cuff, are provided for drive bars activated by the lock, esp. on doors. The bar guide-rails (11) are located below the bars (20). In the central area they have a plinth-shaped elevation, engaging an upward-facing protuberance (21) on the drive-bar (20). The edge sections (25) of this are overlapped by lateral strips (14) on the guide-rail (11), which has the protuberance section of the bar extending between the strip's end faces (F), so as to be exposed to the top. The elevation may form two guide strips (16) directed towards the protuberance. Construction is simplified, and the unit is compact in height.</p> |
