Abstract (en)
[origin: EP0204944A1] 1. Latch-type emergency lock, especially for tubular frame doors, comprising an outer follower (12) rotationally movable by an outer handle, an inner follower (14) rotationally movable by an inner handle and arranged coaxially with respect to the outer follower, and a latch-control arm (13'") which engages with the lock latch pin (4') and which is permanently actuatable by the inner follower (14) in the sense of entraining the latch, while on the other hand said latch-control arm is displaceable by the outer follower (12) only by way of the engagement of a coupling nose (32') which is provided on a coupling rocker arm (32) which is vertically displaceable and is pivotally movable by a key-actuatable check device, characterised in that between the inner and outer followers (14 and 12) there is provided a third, middle follower (13) which is rotatably movable and which carries the latch-control arm (13'"), with the outer follower (12) being connected to the middle follower for rotary entrainment by means of the engageable coupling nose (32') and with the inner follower (14) being connected to the middle follower for rotary entrainment by means of entraining cams (13", 14').
