Abstract

The present invention relates to a door lock installed on a front door or on an inner door of a building, and more particularly, to a pull-type door lock in which a latch bolt is operated by pulling a handle so as to enable a user to easily open or close the door. The pull-type door lock includes: a cover disposed on each side of a door; a handle disposed on the cover; and a latch bolt disposed between the covers and operated by the handle. The handle has a "ㄱ" shape and includes a pulling-handle part and an operating part. Here, the operating part is rotatably disposed with respect to a pin which is intended for coupling the handle and which is inserted into the cover and disposed in a Y-axis direction. Thus, when the pulling-handle part of the handle is pulled, the operating part is rotated around the pin for coupling the handle so as to operate the latch bolt.

Description

Pull door lock

The present invention relates to a door lock installed in the entrance or interior doors (doors) of the building, and more particularly, to a pull-type door lock that allows the user to conveniently open and close the door (door) by pulling the handle to operate the latch bolt. It is about.

In general, a door (door) is installed at an entrance to control a person's entry and exit, and the door (door) is used to open and close and a door lock is installed to lock (lock).

Such a door lock is provided between the cover 2 installed on both sides of the door 1, the handle 3 installed on the cover, and the cover, respectively, as shown in FIG. 1 and operated by the handle. It consists of a latch bolt (4).

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 pulling or pushing the handle about a horizontal axis (X axis).

The door lock is installed on the door and exposed to the situation, which is used as one interior decoration, and various types of door locks are provided.

Due to this situation, in recent years, a door lock having a handle formed in a 'b' shape as in Patent Document 2 (Patent Registration No. 10-0315217) and Patent Document 3 (Patent Registration No. 10-0294624) is provided.

Conventional door lock having such a handle having a 'b' shape (see FIG. 2) rotates the handle '3' having a 'b' shape around a horizontal axis (X axis), so that the latch bolt 4 is in the longitudinal direction. It is composed of a structure to move.

As described above, in the case of the door lock having a structure in which the '3'-shaped handle 3' is rotated about the horizontal axis (X axis) to move the latch bolt 4 in the longitudinal direction, it is usually used to open the door. 'The handle in the shape of the upper and lower force is applied to rotate around the horizontal axis (X axis). However, when the '-' shaped handle is applied from the top to the bottom in order to open and close the door as described above, a load is generated inside and the coupling state is loosened due to the rapid wear phenomenon and the loss of elastic force of the elastic member. As a 'b' shaped handle is deflected to the lower side, which has the disadvantage of hurting the aesthetics.

In addition, there is a disadvantage in that the door lock is easily damaged by applying a force from the top to the bottom in order to rotate the handle of the 'b' shape to open and close the door as described above, the user has a 'b' shape to open the door In order to rotate the handle, it is inconvenient to open the door by applying force from the top to the bottom direction and pulling or pushing back and forth again.

The present invention invented to solve the above problems, the handle of the door lock is rotated about the horizontal axis (X axis) without operating the latch bolt, the handle is installed so as to rotate around the vertical axis (Y axis) It is intended to provide a pull-type door lock configured to operate the latch bolt by pulling.

In addition, it is to provide a pull-type door lock that can simplify the structure of the door lock by pulling the handle to operate the latch bolt.

In addition, by pulling the handle from the upper side to the lower side without force to operate the latch bolt to improve the durability, and to provide a pull-type door lock that can easily open and close the door (door).

The present invention for solving the problem to be solved,

In the door lock comprising a cover respectively installed on both sides of the door, a handle respectively installed on the cover, and a latch bolt installed between the cover and operated by the handle, the handle is formed by the letter 'b' pull handle Consisting part and the operating part, the operating part is inserted into the inside of the cover is installed to rotate about the handle coupling pin to pull the pull handle portion of the handle centered around the handle coupling pin installed on the vertical axis (Y axis) It rotates to make the latch bolt work.

That is, the pull handle is formed of a 'g' is formed of a pull handle portion, a coupling pin hole into which the handle coupling pin is inserted and an operation portion formed with a fan-shaped actuating projection at the end; A cover formed with an insertion hole into which the operation part is inserted, a coupling pin hole into which a handle coupling pin is inserted, and configured to rotate the operation part inserted through the insertion hole about the handle coupling pin; A latch bolt disposed between the covers and having an insertion hole into which a fan-shaped actuating protrusion is inserted; It is composed of a return spring for returning the pull handle to its original state.

Locking groove is formed in the operating portion of the handle, it may further comprise a locking device is formed between the cover is formed with a locking pin that is inserted into or removed from the locking groove to rotate.

The latch bolt is formed in a cylindrical shape, a through hole is formed so that a fan-shaped actuating protrusion can be inserted into an outer circumferential surface thereof, and a housing in which a blocking pin for blocking an end is installed at one side thereof and accommodated inside the housing, It consists of an operating shaft formed with a through-hole so that the fan-shaped actuating projection inserted through it, and an elastic spring accommodated inside the housing to impart an elastic force to the operating shaft.

Pulling door lock of the present invention made as described above, the latch bolt is operated by pulling the handle can be opened and closed the door more easily.

In addition, the pull-type door lock of the present invention, the structure is simple and durable by pulling the handle to operate the latch bolt.

In addition, the pull door lock according to the present invention has a durability of the handle is simple because the locking device is not integrally formed on the handle.
