Description

Automatic locking device for upper cabinet

The present invention relates to an automatic locking device for an upper furniture cabinet, and more specifically, an automatic locking device for an upper furniture cabinet to prevent the door of the upper furniture cabinet or a drawer of the furniture cabinet from opening automatically when vibrations such as earthquakes are detected. It is about the device.

Generally, the storage furniture is furniture used to store and store various items, and a storage space is formed inside and a door for opening and closing the storage space is installed on the front surface.

At this time, the door is installed to open and close the storage space by a hinged method that rotates around a hinge installed in the furniture body, or is installed to open and close the storage space by sliding the door in a sliding direction.

However, when a large vibration is transmitted to the furniture due to an earthquake or the like, and the furniture is shaken, the door is opened, and various items stored in the storage space are poured out, and, of course, damage to the product may occur. Anyone under it can cause serious damage.

In order to overcome this problem, in the prior art, when a vibration occurs due to an earthquake, the locking of the furniture door is activated by itself so that household items such as dishes stored in the furniture can be prevented from leaking or falling outside the furniture. One locking device is disclosed.

1, the locking device is installed in the door lock body unit 10 installed in the furniture body so that the first locking unit 11 is in a seesaw motion, and the door lock body unit 10 is equipped with furniture. When the vibration occurs, 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, and the furniture body has a rotatable structure. The provided door is configured to be installed with 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 opening.

In such a 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 it is made of, there is an advantage that can be prevented from spilling the goods stored inside the furniture in the event of an earthquake.

However, in the case of the locking device disclosed in Patent Document 1, the first locking unit 11 operates by using the weight of the load adding unit 12, resulting in poor reliability of operation, due to irregularity in the direction of earthquake vibration. Due to the problem that the stable operation is not guaranteed when the load adding unit 12 does not fall to the shank east part 13 of the first locking unit 11 and falls to a different position, and to unlock the lock, the door lock main unit 10 Although the user has to press the installed original restoration pressing unit 14 directly, the door lock main unit 10 is located inside the main body of the furniture, so there is a problem in that it cannot be operated while the door is closed.
