Abstract
A door handle assembly has an emergency-unlocking function, so that even in a condition in which a latch bar 2 of the assembly is locked on a front side of a door 4, it is possible for a user to unlock the assembly from a rear side of the door 4 within fail. A socket member 8 is pivoted to a socket-member casing 6 through a vertical pivot 9, the casing 6 being fixedly mounted on a stationary frame element 7. In the rear side of the casing 6, a manually-operated pedal 12 is pivoted to a pedal casing 11 through a first horizontal pivot 13, the pedal casing 11 being fixedly mounted on the frame element 7. A base-end portion of a holding rod 14 is pivoted to one end portion of the pedal 12 through a second horizontal pivot 15 to have a front-end surface of the rod 14 abutted on a stop portion 19 of the socket member 8, the stop portion 19 being disposed behind the pivot 9. The rod 14 is urged forward by a spring 20 contacting the pedal 12.
