DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is, a hinged door of furniture such as cupboard to put a chest of drawers and tableware, and automatic locking to sway when makes moving the earthquake or furniture, also in automatic if the shaking is stationary Automatic unlocking device for unlocking and automatic unlocking
The present invention relates to a hinged door furniture using a fixture to prevent the door from opening .

[0002]

2. Description of the Related Art Even if a conventional anti-shake fastener for preventing furniture from being opened is an automatic locking type, the locking is performed by a forced locking method using a spring or a magnet at the same time as the door is closed regardless of vibration such as an earthquake, or swinging. However, even with the automatic locking method in connection with the above, these unlocks are forcibly unlocked by turning or pushing or pulling the handle of the hook portion of the seismic fastener.

[0003]

Most of the conventional anti-shake fasteners for preventing the furniture from opening are manually operated at the time of unlocking and unlocking, and all of them are further provided on the main body side of the furniture and the door side thereof. It was necessary to attach a pair of mating fasteners to each.

Therefore, in order to attach one of a pair of mating counterparts of the anti-shake fastener to the interior of the furniture main body and the inner or outer surface of the hinged door or one surface thereof, a projection is provided on the interior of the furniture main body and one surface of the hinged door . There is a possibility that the protrusions may be caught by the protrusions when the storage items are taken in and out of the furniture and the doors are opened, and there is a risk of damaging the human body or objects.

[0005] The present invention has been developed for furniture hinged doors because of these problems .
Locking to prevent opening due to an earthquake and unlocking due to static of the earthquake
Was prevented from jumping out of the stored item by operating all automatically, in order to further configured without requiring structure to attach the fitting part associated with the automatic solution locking device on the inner and outer surface of the hinged door, projections on the hinged door It is intended to provide a door- opening furniture with an automatic unlocking device for earthquake prevention which is highly safe even in daily opening and closing without occurrence of opening.

Smooth down from the front to the back
The inside of the lower opening grooved frame 4 and the horizontal frame
6 forms an inclined space with the upper surface of 6 and incorporates a rolling element 8
I do.

The tilt shown in FIGS. 1 to 5 and FIG.
The rolling element 8 built in the space C is in the normal state shown in FIG.
, The vertical center point of the rolling element 8 itself is slightly
The rear frame is brought into contact with one end of the receiving piece 9 so that the horizontal frame 6
4, that is, the rear part in the inclined space C (FIG. 4)
Installed in a state of stopping at the center of the left and right (on the left side)
You. Incidentally, when the rolling element 8 vibrates, its vertical center point is
Becomes locked from the time point when exceeds the eccentricity 7.

The automatic unlocking device body A of the present invention is shown in FIG.
The upper surface of the fastening flange 2 is closely attached to the lower surface of the upper plate D
Then, as shown in FIG. 6 and FIG.
Attached by fitting to the face, one hinged door E from FIG. 6
As shown in each drawing of FIG. 9, a concave portion B is provided on the upper end surface on the moving side.
Form the receiving part of the spherical stopper 5 and open both
Kido furniture.

At all times, the incorporated rolling element 8 is
As shown by 3, the lower rear portion contacts one end of the left and right receiving pieces 9.
In the center of the rear, and a gentle descent to the rear as shown in FIG.
Behind the upper surface of the inclined horizontal frame 6 (the left side of FIG. 4)
The rolling element 8 is in the unlocked state stopped at
It does not impede the upward movement of the front side of frame 6, and
As shown in Fig. 6, in the daily opening and closing of the door E, a spherical strike
The upper 5 swings freely into and out of the recess B on the upper end surface of the hinged door E.
The door E can be freely opened and closed. By the way, FIG.
When the door E is closed and open
Show.

FIG . 4 shows the normally closed state of the hinged door E.
In the resting state, it stays behind the upper surface of the horizontal frame 6 until then

[0016]

The automatic unlocking device of the present invention can be used for vibrations such as earthquakes.
Automatically opens the furniture door to stop the vibration.
Because it is unlocked, there is no need for human intervention.
Prevents stored items from falling, contributing to safety during evacuation in the event of a disaster
When the vibration stops, the lock is automatically unlocked.
It is profitable.

The main body of the automatic unlocking device is inserted and attached.
The main body is not exposed on the lower surface of the upper plate, and
Daily use because the stopper bracket does not project on the surface
Is also safe.

[0018] If the furniture damaged by the earthquake or fallen or tilted still remains automatic locking, hinged door of the furniture is not opened automatically locked, remove the storage products such as clothing and food dishes
When necessary, the user can forcibly unlock the furniture from the outside while opening the door, open the hinged door, and take out the stored items .

When the furniture is moved, for example, when the furniture is rearranged in a room, the swinging or tilting of the furniture automatically locks the door of the furniture, so that the furniture can be safely and easily moved. .
