Abstract

720,764. Releasable door fastenings; striking plates. IMPERIAL COLD STORAGE & SUPPLY CO., Ltd. Feb. 27, 1953 [March 1, 1952; Feb. 13, 1953], No. 5632/53. Class 44. A releasable door fastening of the emergency exit type comprises a latch formation adapted to be installed on a door, a keeper formation adapted to be'installed on'a door post, the latch formation and the keeper formation 'being arranged to interengage to secure the door on the outside thereof when the keeper formation is held down on the post, a catch adapted 'to hold the keeper formation down on the door post and means to operate the catch from inside the door to release the keeper formation to allow the door to become unsecured. In the arrangement according to Fig. 1, in which a door 10 closes externally on to a post 11 and in which a latch bar 13 is engageable with a keeper 15 on hinges at 16 the post 11, the keeper 15 is retained in the position shown in full lines by a catch 19 formed at the outer end of a shaft 18 extending through the post and rotatable to release the catch, by means of a lever 20. A spring-loaded pawl 21 on the lever 20 engages a rack plate 22 in which the inner end 23 of the shaft 18 is journalled. The end 23 is surrounded by a sleeve 24 and terminates in a head 25, the sleeve and head being formed with co-operating toothed cam surfaces which place the shaft 18 in tension when the catch is in operative position. In another arrangement, Fig. 4, in which a door 27 wedges on to a post 28 the door is secured on the outside thereof by means of a wingnut 31 which engages a bolt 32 hinged to a base portion 33 which is internally threaded and is normally retained on the door post 28 by a threaded head 37 of a rotatable shaft 39 extending through the post, a shaft 40 on the inner end of shaft 39 being rotatable from the inside of the door to release the portion 33 and force open the door.
