Description

[Detailed Description of the Invention] The present invention relates to a door opening prevention device for furniture having a hinged door.

In the past, various furniture fall prevention tools and devices have been devised and implemented to prevent furniture from falling during disasters such as earthquakes, but none that prevent the doors of the furniture from being opened. It didn't exist.

Therefore, even if it is possible to prevent the furniture from falling in the event of a disaster such as an earthquake, if the furniture has a hinged door, such as a cupboard, the door may be opened due to vibration and the furniture may fall. Dishes in the cupboard may be thrown out and directly hit people, or be scattered around the room and be damaged, which could become an obstacle during the evacuation.

The present invention has been developed in view of the above-mentioned conventional problems, and is designed to automatically close the doors of furniture with swing-type doors when vibrations above a certain level are applied to the furniture, such as during an earthquake. The object of the present invention is to provide a door opening prevention device that locks the door and prevents the door from being opened and prevents items stored in the furniture from being thrown out.

For this reason, in the present invention, the door opening prevention device includes a door opening prevention member whose side surface is approximately V-shaped so that the tip can be engaged and detached from the upper part of the door, and a door opening prevention member that is rotatable near the base end of the door opening prevention member. a cover member pivotally attached to the door opening prevention member;
and a weight for holding the door opening prevention member in an unlocked state, the lower surface of the cover member is open, and the rear part of the upper surface of the cover member has a groove in which the proximal end of the door opening prevention member can be retracted. and a fitting hole into which the tip of the weight is loosely fitted, a weight receiver is formed around the fitting hole, and the cover member is attached to the lower edge of both sides of the cover member. The intended purpose is achieved by having a structure in which a locking flange for fixing to the upper surface of furniture is formed.

The present invention will be described below with reference to illustrative embodiments.

Reference numeral a denotes a door opening prevention device, which includes a door opening prevention member 1 whose tip 1a is bent downward at a substantially right angle and formed into a substantially V-shape when viewed from the side, and the door opening prevention member 1.
a cover member 2 rotatably pivoted in the vicinity of the horizontal base end 1b; It is composed of a weight 3 that maintains the state.

The cover member 2 is open on the lower surface side, and is formed in a substantially V-shape when viewed from the side, and has a height such that the front surface can accommodate the bent tip 1a of the door opening prevention member 1. At the rear of the upper surface of the cover member 2, a groove 4 into which the base end 1b of the door opening prevention member 1 can enter and exit, and a fitting hole 5 into which the thin-diameter tip 3a of the weight 3 is loosely fitted are continuously formed. Further, a weight receiver 6 is formed around the fitting hole 5 to receive the weight 3 when it falls. Furthermore, locking flanges 8 for fixing the cover member 2 to the upper surface 7 of the furniture b are formed on the lower edges of both sides of the cover member 2.

The door opening prevention member 1 is rotatably attached to the rear part of the cover member 2 via a support shaft 10 via a bracket 9 provided near the base end 1b of the door opening prevention member 1, and is free to rotate. When the weight 3 is not placed on the proximal end 1b of the door opening prevention member 1, the tip 1a moves downward and projects from the lower surface of the cover member 2.

The weight 3 loosely fits into the fitting hole 5 of the cover member 2, and the tip 3a placed on the upper surface of the base end 1b of the door opening prevention member 1 has a small diameter, and the head 3b falls over when vibration exceeds a set value. It has a large diameter, and
The step 3c on the tip 3a side is the fitting hole 5 of the cover member 2.
It is designed to maintain the upright position by engaging with the periphery of the holder.

In order to install the door opening prevention device a configured as described above on the upper surface 7 of the furniture b, the door opening prevention member 1 is fixed so that the tip 1a thereof protrudes from the front surface of the furniture b.

At this time, if the furniture b is not placed horizontally, it is desirable to adjust the height adjustment screw 11 attached to the cover member 2 to install the door opening prevention device a horizontally.

After the door opening prevention device a is fixed, a weight 3 is placed on the upper surface of the base end 1b of the door opening prevention member 1, as shown in FIG.

As a result, when an earthquake occurs and vibrations exceeding the set value occur, the weight 3 falls and rolls into the weight receiver 6, and the tip 1a of the door opening prevention member 1 lowers to the front of the upper part of the door 12 of furniture B. The opening of the door 12 is prevented.

In addition, a magnet 13 is fitted into the part of the furniture b where the door opening preventing member 1 is located.
By adsorbing the door opening prevention member 1, it is possible to prevent the door opening prevention member 1 from flying up and to more reliably prevent the door 12 in general from opening. If the door opening prevention member is made of resin, a magnet may be fitted into the door opening prevention member and an iron piece may be attached to the furniture side.

As described above, according to the present invention, when vibrations exceeding a set value occur due to earthquakes, etc., the doors of furniture, etc. are automatically prevented from opening, thereby preventing items stored inside the furniture from being thrown out. could be prevented. Therefore, since the stored items will not be scattered around the room or hit people's bodies, it is possible to not only safely and quickly evacuate the items, but also prevent damage to the stored items. can.
