<p>PURPOSE:To miniaturize a device in reducing each occupited space of respective parts by engaging a release lever and a lift lever of a locking mechanism operating a latch mechanism in a door via an open lever with a circular long hole. CONSTITUTION:An engaging piece 51a is installed in a lift lever 51 constituting a locking mechanism 5, operating a latch mechanism 3 installed in a housing in a door, a circular long hole 52a in an open lever 52 and an engaging piece 53c in a release lever 53 respectively, and both these levers 51 and 53 are installed there in holding the open lever 52 between. In time of unlocking, a handle 58 is operated and the open lever 52 is rotated counterclockwise, rotating a pole 34, and it is unlocked. In addition, selection between both locking and unlocking states of a door locking device 1 is carried out by the release lever 53 connected to a rocking lever 54. With this constitution, an occupied space of the locking mechanism 5 is reduced and, what is more, this device can be miniaturized in this way.</p> |
