ABSTRACT:
A rim lock which includes a housing, a bolt displaceable in the housing, a strike which receives the bolt, a solenoid which is mounted on the housing and has a coil, a plunger which is axially reciprocal in the coil, a crosspiece fin which is disposed between and which is rigidly affixed to the plunger and the bolt, a front inner lever which has at least one pin and is rotationally mounted in the housing and is in mechanical communication with the crosspiece fin, a spring which is operatively braced between the crosspiece fin and the housing, apparatus which electrically energizes the coil, holding appartus which are operatively engageable between the bolt and the housing and mechanically retains the bolt, a key operated lock cylinder, a rear inner lever which has at least one pin and is rotationally mounted in the housing and is in mechanical communication with the crosspiece fin, and coupling apparatus which includes an interchangeable backset plate which is engaged between the key-operated lock cylinder and the bolt and which displaces the bolt axially upon operation of the key-operated lock cylinder. The interchangeable backset plate is one of a plurality of interchangeable backset plates each being removably mounted to the housing and each having a different backset so that a single rim lock can fit on doors with different size stiles and required backsets.
