Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a door locking device for preventing a double-opening door or a single-opening door such as a cabinet or other furniture from being opened accidentally due to vibration or the like.

[0002]

[Prior art]

 Double doors or single doors such as cabinets and other furniture use various door closing tools that hold the doors closed for easy opening and closing. For example, a support member that supports the door so that it can be opened and closed has a spring function that urges the door in the direction to close it, and when opening the door, it opens against the urging force of the spring and keeps that state and closes. In this case, the door is returned by simply releasing the hand (conventional example 1). In addition, a magnet is provided on one side of the door and at a position around the door where the door is closed, and a magnetic material is provided on the other side to close the door by using the magnetic attraction force.When opening, the door is opened against the magnetic attraction force. There is one that has been designed (conventional example 2).

In addition, a protrusion member is provided on one side of the door and a position around the door at a position where the door is closed, and a concave member is provided on the other side, and the fitting force of both is used to close the door, and when the door is opened, the fitting force is applied. There is one that opens the door against. In this case, the protruding member is made of metal and the concave member is made of metal having a spring force in the clamping direction, or the protruding member is made of a metal ball that moves in and out by the spring force, and the concave member has a ball receiving hole. Arbitrary configuration, such as the one described above, is taken (conventional example 3).

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional examples have the following problems. In Conventional Example 1, the biasing force of the spring is used to hold the door in a closed state. Therefore, due to an earthquake, etc. It may push it open. Naturally, the stored items pop out. To prevent this situation, if a strong spring material is used to prevent the door from being pushed easily, it is not easy to hold the door in the open state when opening the door on a daily basis. It will be difficult with the help of old people and infants.

Further, in Conventional Example 2, since the door is held in a closed state by utilizing the magnetic attraction force of the magnet, similar to Conventional Example 1, the cabinet, furniture, etc. are tilted due to an earthquake or the like. Objects stored inside may move and push the door open. When the magnetic coercive force of the magnet is strengthened in order to prevent this situation, there is the same problem as in Conventional Example 1.

Further, in Conventional Example 3, since the fitting force between the protruding member and the concave member is used to hold the door in a closed state, the same problem as in Conventional Example 1 occurs, and If it is used for a long period of time, the spring force in the clamping direction of the recessed material will be fatigued and the fitting force will deteriorate. Therefore, there is a problem that the force for holding the door in the closed state becomes insufficient, and the door is more easily opened by the stored items that have moved.

The present invention is proposed to solve the above problems, and a door locking device that prevents the door of a cabinet, other furniture, or the like from opening even when an unexpected situation such as an earthquake occurs. The purpose is to provide. Another purpose is to keep the door locks exposed to the outside of the door to the minimum extent so that it does not spoil the aesthetics of cabinets and other furniture.
