<p>#CMT# #/CMT# The device (1) has a locking bolt (14) with a shaft (18) arranged vertical to an edge of the device, where the shaft has stops (15, 19) arranged at its respective longitudinal ends. The bolt is biased toward the edge in an unlocking state of the device of a support e.g. retaining plate (32), in a normal position. The support is released in the bolt during fire such that the bolt is driven by a biasing device with the shaft extending through the holes and is moved parallel to the edge, so that the bolt forms respective undercuts on the edge and on another edge with the stops. #CMT# : #/CMT# The biasing device is designed as a helical compression spring. #CMT#USE : #/CMT# Fire protection locking device for a lift sliding door (claimed) in a building. #CMT#ADVANTAGE : #/CMT# The support is released in the locking bolt during fire such that the bolt is driven by the biasing device with the shaft extending through the holes and is moved parallel to the edge, so that the bolt forms respective undercuts on the edge and on another edge with the stops, thus preventing excessive divergence of the edges, and hence reducing expanding measure of a lift sliding door during fire. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a fire protection locking device. 1 : Fire protection locking device 14 : Locking bolt 15, 19 : Stops 18 : Shaft 22 : Helical compression spring 32 : Retaining plate.</p> |
