Description

&Quot; PUSH AND PULL DOOR LOCK "

The present invention relates to a push-pull door lock which allows a user to easily use the latch by pushing (PUSH) or pulling (PULL) the latch according to the opening direction of the door.

Generally, a door (door) is provided at an entrance to control the entrance and exit of a person, and a door lock is provided to the door so that it can be used for opening and closing.

Such a door lock generally comprises a cover provided on both sides of a door, a handle provided on the cover, and a latch bolt provided between the cover and operated by a handle.

The conventional door lock has a structure in which the latch bolt is moved in the longitudinal direction by rotating the handle. When the door is opened, the door is opened by rotating the handle about the horizontal axis (X axis) So that various types of door locks are provided.

According to such a situation, door locks provided with a handle made of 'a' 'shape are provided as in Patent Documents 10-0315217 and 10-0294624.

The conventional door lock having the 'A' shape has such a structure that the latch bolt is moved in the length (horizontal) direction by rotating the 'A' shaped handle around the horizontal axis (X axis).

In the case of the door lock, which is a structure in which the latch bolt is moved in the longitudinal direction by rotating the 'A' shaped handle about the horizontal axis (X axis) as described above, the handle of the ' To rotate about the horizontal axis (X axis). However, when a force is applied from the upper part to the lower part of the 'A' shaped handle to open and close the door in this way, a load is generated in the inside, and due to the rapid wear and return of the elastic member, Is loosened, the 'A' shaped handle is deflected downward, which causes a deterioration of aesthetics.

In addition, since the force is applied from the upper part to the lower part (i.e., the vertical direction) in order to rotate the 'A' shaped handle in order to open and close the door as described above, the door lock is easily broken, It is inconvenienced to apply the force from the top to the bottom in order to rotate the handle of the 'A' shape and to open the door by pulling or pushing back to the front and back

In order to solve such a problem, Japanese Patent Registration No. 10-1059753 provides a pull-type door lock having a structure in which the latch bolt is moved in the length (horizontal) direction when the handle is pulled in the horizontal direction.

However, in the case of the pull-type door lock of the above-mentioned Japanese Patent No. 10-1059753, the door is configured to operate in a pulled manner on both the inside and the outside of the door, so that either the inside or the outside pulls in a direction opposite to the opening direction of the door .

In order to solve such a problem, Japanese Patent Registration No. 10-1375776 discloses a push-and-pull opening type door lock which allows one handle to be operated in a pulled manner while the other handle is operated in a push-pull manner Respectively.

(KR) Patent Registration No. 10-0315217 (Registration date November 8, 2001) (KR) Patent Registration No. 10-0294624 (registered date April 18, 2001) (KR) Patent Registration No. 10-1059753 (registered date August 22, 2011) (KR) Patent Registration No. 10-1375776 (registered on March 12, 2014)

The present invention intends to provide a door lock of a push-and-pull type, which allows the user to open the door more easily than a pull door type door lock such as a pull door type door lock of the prior art 10-1059753.

That is, it is desirable to provide a door lock that operates in a push-and-pull opening manner as in the prior art 10-1375776, but provides a push-and-pull door lock of a different configuration.

To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a push-pull door lock includes a push handle mounted on one side of a door, a pull handle mounted on the other side, The push handle includes a first handle rotatable about a first handle rotary shaft pin and a first actuating shaft rotary shaft pin for rotating the latch of the latch bolt such that the door rotates when the first handle rotates, Wherein the first handle and the first actuating part comprise a gear type transmission structure using a plurality of the first handle and the first actuating part to move the latch of the latch bolt backward when the first handle is pushed,

The pull handle includes a second handle that rotates about a second handle rotary shaft pin and a second operation about a second actuating shaft rotary shaft pin that rotates during rotation of the first handle to move the latch of the latch bolt backward Wherein the second handle and the second actuating part have a link type transmission structure using a link so that the latch of the latch bolt can be retracted when the second handle is pulled.

Further, the push-pull door lock of the present invention, which is another solution, is characterized in that in a push-and-pull doorlock including a push handle provided on one side with respect to a door, a pull handle provided on the other side and a latch bolt provided in the door The latch bolt includes: a cylinder slider installed to slide in the cylinder housing; The cylinder slider is installed on the front surface of the cylinder slider so that one end of the cylinder slider protrudes outside the cylinder housing so that one end thereof is inserted into the groove formed in the door frame. A latch that is resiliently urged to return; A first slider for releasing function that is slidable in the direction of movement of the latch in the cylinder slider and slid solely and is coupled to the cylinder slider so as to be retracted when retracted and connected to either the push handle or the pull handle, A slider including a second slider for function; The first and second sliders are moved in a direction orthogonal to the moving direction of the slider so as to be positioned at the locked position and the unlocked position so as to restrict the sliding of the cylinder slider, When the second slider is retracted, the lock member can be held in a locked state by preventing the lock member from being moved from the locked position to the unlocked position when the second slider is retracted. .

According to the present invention, a push-and-pull door lock is provided with a push handle, a pull handle, and a latch bolt having a different structure from that of the conventional structure, so that the push handle and the pull handle It has the advantage of being able to control the position (indoor and outdoor sides around the door) and smooth operation.
