In such a case, the mechanism for opening and closing the conventional cabinet door has not been largely changed. As shown in FIG. 1, the cabinet door opening / closing mechanism generally includes a handle provided on the outside of the door, the handle being rotatable for opening and closing; A rotary plate inside the door that rotates together with the rotation of the handle; A circular rod that linearly moves in a vertical direction in accordance with rotation of the rotary plate; And a through hole provided in at least one of an upper portion and a lower portion of the cabinet door. The cabinet door is opened and closed by inserting or exposing the round bar into the through hole.

However, there is a problem in that the door opening / closing mechanism opened and closed by the vertically moving round bar inconveniently cuts the round bar in an exact size according to the size of the cabinet door, and when the size is not correct, do.

Patent Document No. 10-0913217 (published on August 24, 2009)

It is an object of the present invention to provide an opening and closing mechanism for a cabinet door that has flexibility in production by replacing a round bar of iron which moves up and down to move up and down to fit a cabinet of various sizes.

It is an object of the present invention to provide an opening and closing mechanism for a cannonet door that can be opened and closed smoothly when the cabinet door is opened and closed

.

According to an aspect of the present invention,

A handle (10) provided on the outside of the door so as to be rotatable for opening and closing the cabinet door;

A rotating plate (20) rotatable in association with the handle, the rotating plate having at least one through hole and provided inside the door;

A spring 32 provided between the through holes of the bracket 31 and a lock bar 33 penetrating the spring 31. The lock bar 33 is provided on the lock bar 33, An opening / closing part 30 including a stopper 34 for fixing the position of the stopper 34;

A belt (40) having one end connected to a lower end portion of the lock bar and the other end connected to a through hole of the rotation plate; And

By including the through hole (103) in at least one of the upper portion and the lower portion of the cabinet body,

The end of the lock bar 33 is inserted into or exposed from the through hole 103 due to the pulling of the belt 40 in the pull direction or the restoration by the spring as the rotating plate is rotated in conjunction with the external handle, And is a cabinet door opening / closing device for opening and closing a cabinet door.

The present invention improves the flexibility of production of the cabinet opening / closing mechanism by replacing the iron bar of the cabinet opening / closing mechanism with a belt so that it can be compatible with various sizes without the need to manufacture a working rod specifically for cabinet size.

The present invention has the effect that the roller is provided at the end of the lock bar so that it is smoothly inserted or exposed in the lock groove of the cabinet body, thereby reducing noise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings, and the inventor may appropriately design the concept of the term appropriately to describe its own design in the best way possible. It should be interpreted as a meaning and a concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in the present specification and the constitutions shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, various equivalents It should be understood that water and variations may be present.

2, an operation state of the opening and closing apparatus that operates in conjunction with the rotation of the handle provided on the front surface of the door for opening and closing the cabinet door will be described.

The left drawing shows a state in which the door is locked, and a belt connected to both ends of the rotation plate is connected to the locking bar 33 of the opening and closing part. That is, when the door is locked, the rotary plate is positioned in the vertical direction, and the belt 40 is connected to both ends of the rotary plate. The lock bar 33 is fixed to the upper end or the lower end of the cabinet body by the elastic force of the spring, As shown in Fig.

However, if the user rotates the handle located on the front of the door to open the door, the rotary plate on the rear side of the door, which is in communication with the handle, rotates in the horizontal direction, thereby pulling the belt connected to both ends of the rotary plate. The belt pulls the lock bar 33 inserted in the lock groove 103 of the cabinet body in the direction of the handle and the lock bar 33 is exposed from the lock groove provided at the upper or lower end of the main body, The device is released and the door can be opened.

3 is a more detailed view of the operating state of the present invention. The handle shown in the left side view of FIG. 3 is a handle provided on the switchboard, and is held in a state where it is seated in the handle receiving groove provided in the door, so that the door can be selectively protruded when the user needs to open the door It is a commonly known door handle.

After the door handle is once protruded from the handle mounting groove, the door handle is pivoted by the user. At this time, the rotary plate provided on the rear surface of the door rotates in conjunction with the handle. At this time, it is preferable that the handle and the rotary plate maintain the same direction. That is, when the knob is turned to the right (counterclockwise) and becomes the horizontal state, the rotary plate is also rotated in the vertical direction and in the horizontal direction.

The belt connecting the one end of the locking bar 33 and one end of the rotating plate does not change its length but when the rotating plate is rotated in the horizontal direction as in the case of the knob rotated in the horizontal direction, .

The belt pulled in the handle direction by the rotation plate pulls the lock bar 33 and the spring 32 provided on the outer periphery of the lock bar 33 is compressed by the stopper 34, The lock bar is inserted again into the lock groove provided at the upper or lower end of the cabinet body by the compressed spring force. Here, the stopper 34 may be provided in various forms. The stopper 34 may be formed by forming a pinhole (not shown) in the middle of the lock bar 33 and inserting a pin into the pin hole, It is also possible to fix the ring rim protruding to the outer circumference in the middle.

However, it is preferable that a roller is provided at the other end of the lock bar 33. This configuration minimizes the friction when the other end of the lock bar 33 is inserted into or exposed from the lock groove 103 of the cabinet body, and even when the door is not accurately positioned due to the deformation of the door in the future, Or to be opened.

The belt 40 is provided with connecting hooks 41 and 42 so as to be connected to the through hole of the rotating plate and to the end of the locking bar 33. The length adjuster provided at the middle portion of the belt So that it can be adjusted. The length adjusting part adopts a generally used length adjusting method.

FIG. 4 is an enlarged detail view of the opening / closing part 30, and will be specifically described on the basis thereof. The opening and closing part 30 has a bracket 31 fixed to the upper or lower end of the rear surface of the door so that the bracket 31 supports the locking rod 33 in a stable manner The lock bar 33 is inserted between the through holes and inserted through the spring so that one end of the spring 32 is restricted by the stopper 34 from moving in one direction do. The stopper 34 for restricting the position of the spring is preferably a pin inserted through a pin hole provided in the middle portion of the lock bar 33, but not limited thereto, and various stoppers may be employed.

Although the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention has been described with reference to the "cabinet door opening and closing device" having a specific shape and structure. However, And should be construed as falling within the scope of protection of the invention.
