Description

Automatic Locking Device for Upper Cabinet

The present invention relates to an automatic furniture locking device, and more particularly, to an automatic furniture locking device capable of preventing a door or drawer from being opened by automatically operating when vibration such as an earthquake is sensed.

In general, storage furniture is a piece of furniture used to store and store various items, and includes a storage space formed therein and a door for opening and closing the storage space installed on the front side.

In this case, the door is installed to open and close the storage space in a hinged manner that rotates around a hinge installed on the furniture body, or is installed to open and close the storage space in a sliding manner in which the door is pushed and pulled in the lateral direction.

However, when a large vibration is transmitted to the furniture due to an earthquake, etc. and the furniture shakes, the door is opened and various items stored in the storage space are poured out, which can cause damage to the items as well as If there are people under it, it can cause serious damage.

In order to overcome this problem, in the prior art, when vibration occurs due to an earthquake, etc., the lock of the furniture door is activated by itself to prevent household items such as dishes stored inside the furniture from leaking out or falling to the outside of the furniture. A locking device is disclosed.

1 , the locking device is installed so that the first locking unit 11 performs a seesaw motion on the door lock body unit 10 installed on the furniture body, and the interior of the door lock body unit 10 includes furniture. A load adding unit 12 is installed to induce a seesaw motion of the first locking unit 11 by pressing one end of the first locking unit 11 while falling when vibration occurs, and the furniture body has a rotatable structure. A second locking unit (not shown) that is coupled to the first locking unit 11 by the seesaw movement of the first locking unit 11 to prevent the door from being opened is installed in the provided door.

In this locking device, when the furniture vibrates due to an earthquake, the load-adding unit 12 disposed at a predetermined position of the door lock body unit 10 falls, thereby automatically locking the door while the first locking unit 11 operates. Since this is made, there is an advantage in that it is possible to prevent the items stored inside the furniture from spilling out in the event of an earthquake or the like.

However, in the case of the locking device disclosed in Patent Document 1, the first locking unit 11 operates using the weight of the load-adding unit 12, so the reliability of operation is lowered, and the earthquake vibration direction is irregular. Due to this, the load adding unit 12 cannot fall to the vertical moving part 13 of the first locking unit 11 and a stable operation is not guaranteed when it falls to another position, and in order to unlock the door lock body unit 10 Although the user must directly press the installed restoration pressurization unit 14, the door lock body unit 10 is located inside the furniture body, so there is a problem in that it cannot be operated when the door is closed.
