Message door lock apparatus
First Claim
1. A message door lock comprising:
- a casing secured inside a door;
a recording and playing circuit means having a recording and playing circuit mounted in said casing for operatively recording a message speech therein and for playing or outputting the message speech therefrom, and having a trigger switch operatively actuating a first contact and a second contact electrically connected with said recording and playing circuit for triggering said recording and playing circuit means for playing a recorded message pre-recorded therein; and
a trigger means formed on a door lock operatively rotated for triggering said trigger switch of said recording and playing circuit means for playing the recorded message pre-recorded in said recording and playing circuit means;
said recording and playing circuit means including;
a main switch for switching on or off of a power source of the circuit means, the trigger switch operatively actuated by said trigger means for conducting the first contact and the second contact both contacts normally opened and operatively closed to be connected to the recording and playing circuit having function for receiving input speech signal when recording for the memory of the input speech signal and for outputting speech signal which is transduced as audible speech when playing a lamp indicator selected from a light emitting diode which is lit indicating the circuit ready for recording and is flashed indicating the circuit ready for playing, a microphone for receiving the input speech signal when recording, and a loud speaker for sounding the audible speech when playing; and
said trigger means including;
a thumbturn secured on an inner end portion of a sleeve portion rotatably mounted in the casing, a spindle secured in the sleeve portion and the thumbturn of the trigger means protruding outwardly along a longitudinal axis to be secured with a deadbolt to be operatively locked on a door frame and secured with a locking core of the door lock formed on an outside of the door, and a trigger-switch actuator secured on a middle portion of the spindle to be operatively rotated within the casing.

Abstract
A message door lock includes a trigger switch for trigging a playing operation of a recorder and player operatively recorded for leaving a message in the recorder formed on a door lock, an actuator of the trigger switch mounted on a thumbturn or doorlock spindle having an insulator flange normally interrupting the trigger switch from a circuit of the recorder and player and having a pair of notches diagonally recessed in the flange, whereby upon a rotation of the thumbturn inside a door or unlocking the doorlock outside the door, the flange of the actuator is rotated to match the notch in the flange with the trigger switch for resiliently contacting the trigger switch with the contact of the recorder and player circuit for playing the message already recorded in the recorder whenever rotating the thumbturn or unlocking the doorlock for a convenient and safe messaging purpose.
