Description

Push-pull type door lock < RTI ID = 0.0 >

The present invention relates to a door lock, and more particularly, to a push-pull door lock capable of opening and closing a door through a push or pull operation.

Generally, a door lock is installed in a door installed in an entrance or a building for opening and closing a door.

The door lock includes a mortis provided on the door and provided on both sides of the door so as to be interlocked with the motis, and a lever that retracts or draws the latch bolt into and out of the door lock striker provided in the door frame.

In such a door-type door lock, the user opens or closes the door by pulling or pulling the latch bolt into or out of the door lock striker of the door frame by forward or reverse rotation of the lever about the axis of the latch bolt.

Such a lever-type door lock has the advantage that the door can be easily opened and closed by rotating the lever unidirectionally without a separate locking device or a fixing device. However, it is troublesome in terms of structural operation to rotate the lever about the latch bolt axis while holding the lever. , There is a disadvantage that the lever can not be operated in a state in which the user can not use the hand.

As a prior art for solving such a problem, Korean Patent Laid-Open No. 10-2016-0098785 (published on Jan. 201, 2019) discloses a push-pull type door lock.

The first and second actuating parts 113 and 123 extend to the first and second gripping parts 111 and 121, respectively. The first and second actuating parts 113 and 123 act as push and pull type actuators. First and second movable cams 131 and 133 having first and second insertion grooves 113a and 133a and interlocking with the rotation of the first and second actuating parts 113 and 123 and having first and second movable grooves 135, And a movable protrusion 140 which is simultaneously inserted into the first and second movable grooves 135 and has a shape corresponding to the first and second movable grooves 135.

This patent has an advantage that the door can be opened and closed by a simple operation of pushing or pulling the first and second grippers 111 and 121.

However, when the first and second grip portions 111 and 121 are pushed to open and close the door, the first and second movable grooves 135 and 135 and the first and second movable grooves 135 and 135, The push bolt movement of the first and second grips 110 and 120 is not smooth due to the structure in which the latch bolt 170 is operated by the movable protrusion 140 which is linearly moved when the first and second movable grooves 135 are rotated And the frictional surfaces of the first and second movable cams 131 and 133 and the movable protrusions 140 are worn out severely when used for a long period of time.

[ Further, the unlocking portion 330 is unidirectionally rotated by the first power transmitting member 150 when the first operating lever 130 is push-pulled forward and backward while the lock button portion 310 is in the locked position The lock button unit 310 is rotated to the unlocked position.

An example of the structure of the unlocking part 330 will be described in more detail. When the lock button part 310 is locked and the first operation lever 130 is operated in a push-pull operation, A locking protrusion 331 is formed which is unidirectionally rotated by a lock releasing protrusion 159 protruding from the power transmitting member 150.

The locking protrusion 331 may be formed radially outward of the unlocking portion 330. The locking protrusion 331 may protrude from the lower portion of the unlocking portion 330 so as to be in close contact with the locking protrusion 159 when the locking button 310 is in the locking position.

The lock protrusion 331 is in close contact with the lock release protrusion 159 and is locked by the lock release protrusion 159 which is rotated in one direction in the pushing operation of the first operation lever 130, So as to be rotated to the unlock position.

Then, the lock portion 350 is rotatably coupled to the fourth coupling hole 217 formed on the second mounting surface 211. [ The locking portion 350 is engaged with the second power transmitting member 250 to prevent the second operating lever 230 from being pushed forward and backward when the locking button portion 310 is in the locked position, The second operation lever 230 is unlocked from the second power transmitting member 250 so that the second operation lever 230 is unlocked so that the second operation lever 230 is pushed forward and backward.

More specifically, the lock portion 350 may be formed on the turning surface 259 formed on the second power transmitting member 250 when the lock button portion 310 is locked, And a lock part 350 formed with an interference protrusion 351 which is in close contact with the rotation surface 259 and is disengaged from the rotation surface 259 when the first operation lever 130 is operated in a push-pull manner.

The interference protrusion 351 may protrude radially outward of the lock portion 350. [ The interference protrusion 351 is provided in the case where the lock button portion 310 is in the locked position

And may protrude downward from the lock portion 350 so as to be in close contact with the turning surface 259 formed on the upper portion of the second power switching member 250.

That is, the interference protrusion 351 is brought into close contact with the turning surface 259 when the locking button portion 310 is in the locked position, so that the second power transmitting member 250 is prevented from turning, To prevent the forward and backward push-pulls. At this time, when the first operation lever 130 is operated in a push-pull operation, the locking projection 159 unidirectionally rotates the locking projection 331. When the locking button portion 310 is rotated to the unlocking position, The second operation lever 230 is released from close contact with the rotation surface 259 so that the second operation lever 230 can be operated in the forward and backward push-pull operation.

As described above, according to the embodiment of the present invention, the door can be quickly and easily opened and closed by simple operation of pushing and pulling the door lock knob, and even when the door lock is in the locked state, the door lock knob So that the door can be quickly opened and closed.
