Abstract

The present invention relates to a door lock apparatus for a door (2) rotatably attached onto a door frame (1) fixed in a wall of a building, wherein a door lock (10) having a latch (12), which is extended or retracted by the rotation of a handle (11), is attached to the door (2), and a stopper piece (20) is installed in the door frame (1) to lock or unlock the latch (12) of the door lock (10). The door lock (10) is provided with an impact-relieving roller (30) for preventing the door (2) from directly colliding against a stepped protrusion (1a) of the door frame (1) and banging when the door (2) is shut. The impact-relieving roller (30) is provided in such a manner that the impact-relieving roller (30) is pressed by the resilient force of a compression coil spring (40). The impact-relieving roller (30) is pressed by the door (2) to overcome the resilient force of the compression coil spring (40) and is brought into contact with the door frame (1) when the door (2) is shut. The impact-relieving roller (30) returns to the original position thereof by the restoring force of the compression coil spring (40) when the door (2) is opened. The latch (12) of the door lock (10) includes an impact-relieving pad (19a) for absorbing the impact sound generated during the extension or retraction of the latch (12), and a guide member (19b) for guiding the linear extension or retraction action of the latch. The handle (11) has a stopper (11c) contacting a return spring (11b) and having an impact-relieving pad (11d) attached thereto to eliminate an impact sound generated by the direct collision of the return spring (11b) with the stopper (11c) when the handle (11) swings or returns to the original position thereof.
