Embodiment Construction

[0025] Now, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0026] figure 1 is a perspective view of an assembled state of the door lock device according to the present invention. As shown, the door lock device of the present invention includes a handle shaft 11 that transmits linear motion. The handle shaft 11 has a first handle 12 on one side and a second handle 14 on the other side.

[0027] Such as figure 1 As shown, the first and second handles 12 and 14 are both 'A' shaped, but may be of different shapes, such as spherical, circular, etc.

[0028] The handle shaft 11 is provided with a handle shaft support 40 formed to surround the outer peripheral surface of the handle shaft 11 and has an opening through which the handle shaft 11 passes in a fitted-in manner so that the handle shaft support 40 is used to guide and support the handle shaft 11 . The handle shaft support 40 has a hole formed on ...

Abstract

Disclosed is a door lock device that can easily open and close a door just by pushing or pulling a handle in one direction, wherein a latch bolt assembly is rotatably mounted in a door lock housing, and pushed by a resilient force of a spring by the action of an operation rod assembly connected to an operation lever, such that when a handle is manipulated at a state where the latch bolt is locked into a door frame, the operation rod assembly is retracted and simultaneously the latch bolt assembly is rotated to release the locking state, thereby making it possible to smoothly open the door with a substantially small force.

Description
