20090008949 | Door Handle Apparatus - The present invention provides a door handle apparatus consisting of a handle, a lock housing, a transmission mechanism, and a locking mechanism. The handle is pivotally engaged with the lock housing. The locking mechanism is engaged with one end of the lock housing and the handle. When the handle is rotated, the locking mechanism makes relative sliding and movement about the handle. The transmission mechanism is engaged with the other end of the lock housing and moves relative to the locking mechanism. The locking mechanism has a burglar free locking piece that prevents the door handle apparatus from being disassembled without being unlocked by a key first. After the door handle is engaged with the transmission mechanism, the door handle is still rotatable and movable via the lock housing. | 01-08-2009 |
20080256995 | Unlock Transmission Mechanism for Escape Door - An unlock transmission mechanism for escape doors is disclosed, including a base, a transmission member, a first drive unit and a second drive unit, wherein the transmission member, the first drive unit and second drive unit are all disposed on the base, and the transmission member is actuated to move relative to the first drive unit and the second drive unit, respectively. In the case that the unlock transmission mechanism is to be installed in an escape door that has a different installation orientation, the transmission member and the first drive unit provided therein have the characteristics of multi-directional changeability, thereby enabling flexible installation of the escape door lock and eliminating the necessity to replace an existing door handle mechanism as encountered in the prior art. | 10-23-2008 |
