Description

[0001]
[Technical field to which the invention belongs]
Each time the furniture placed on the wall swings due to an earthquake and the front side rises, the stepped sliding body automatically enters the lower front side of the furniture due to the elasticity of the spring, The present invention relates to a furniture forward-prevention device for disaster prevention that prevents the furniture from falling forward due to the vibration of an earthquake by tilting and fixing.
[0002]
[Conventional technology]
Conventionally, as a means for preventing furniture from being moved forward due to vibrations such as an earthquake, fixing furniture to a wall surface using a support or L-shaped bracket that connects the upper part of the furniture to the ceiling has been performed. In order to use these fall-preventing devices, valuable furniture is damaged, so a means for not damaging the furniture is required. On the other hand, as a means of not damaging the furniture, by laying a plate-shaped or cross-section inclined forward-prevention device at the lower front side of the furniture and tilting the furniture to the back wall side, the furniture can be tilted forward below a certain seismic intensity. I was prevented from doing it.
[0003]
Moreover, as means for not damaging furniture, there are Japanese Patent Application No. 7-88575 and Japanese Patent Application No. 8-31125 developed by the present inventor, which are applied to the lower front edge of furniture or the lower edge of the side wall of furniture. By moving the stair-like sliding body automatically with spring elasticity to the front lower edge of the furniture or the front side of the side wall where a gap is created by vibration, the furniture is inclined to the wall side at a larger angle than before. It has been done to prevent falling forward.
[0004]
[Problems to be solved by the invention]
The conventional furniture anti-tilt device that protects the furniture without damaging it is designed to lay inclusions at the lower front of the furniture and tilt it to the rear, but the tilt angle is always fixed regardless of the magnitude of the vibration. As a result, there was a limit to the tilt angle even when trying to set the tilt angle for large earthquakes. For example, in the case of a kite, if the tilt angle is large during normal times, the drawer will be heavy and the door will be difficult to open, making it inconvenient, and if the tilt angle is small, the drawer or the door may jump out or fall forward even with small vibrations. there were.
[0005]
The present invention is a furniture forward-prevention device that is installed on the lower side of the lower front edge of the furniture without damaging the furniture and increases the inclination angle of the furniture by using vibrations. This is a significant improvement of -88575. That is, the conventional furniture forward-prevention preventive device, which is a prior application, lays the furniture on the front lower edge in the same manner as in the present invention, but the furniture front lower edge support portion at the front end of the lifting body simply mounts the front lower edge of the furniture. Since the lifting body is not connected to the front lower edge of the furniture, even if the stair-like sliding body moves forward in response to the earthquake vibration, And the board often comes off from the front lower edge of the furniture, and the force to raise the lifting body by the upward spring always acts, resulting in increased detachment, and it was impossible to reliably represent the expected effect .
[0006]
In addition, the conventional furniture front-end preventive tool has a structure of an elevating body and a stepped sliding body for setting an initial inclination angle of the furniture, a structure of a guide and an inner side groove for preventing removal, and the like. Basically, there was a drawback that made the molding means difficult. Furthermore, the sliding body spring that moves the stepped sliding body has a disadvantage that it does not expand and contract accurately because there is no guide, and the sliding body spring is loaded between the rear end of the stepped sliding body and the rear end of the substrate. Therefore, it is necessary to increase the dimension in the depth direction of the substrate, which hinders downsizing and weight reduction.
[0007]
[Means for solving problems]
In the present invention, since the lifting body is detached from the front lower edge of the furniture and the substrate does not fall off, the furniture front lower edge fitting portion of the lifting body is provided with a front edge and a rear edge and is formed in an upward U shape, Next, an adhesive sheet for adhering and connecting the lower front edge of the furniture is attached. Hinge between the rear end of the lifting body with the upper U-shaped furniture front lower fitting part that adheres with this adhesive sheet and supports the front lower edge of the furniture, and the rear end of the board placed on the floor or tatami Connect at the structure. In some cases, an upward front plate is provided on the front end side of the substrate, and when an upward front plate is provided, a through hole is formed in the upward front plate through which a small width restoration portion projecting on the front side of the stepped sliding body passes. In the case of omitting the upward front plate, it is possible to project a wide restoring portion having substantially the same width as that of the substrate on the front side of the stepped sliding body. In addition, the substrate is provided with a side plate that also serves as a guide for the staircase-like sliding body and serves as a left-right detachment stopper.
[0008]
A step-like sliding body that is supported in a state in which the staircase whose lower staircase side faces the front end is in contact with the furniture front lower edge fitting portion is disposed between the lifting body and the substrate. The step-like sliding body has a through-hole formed in a support part provided in a part thereof to penetrate the spring shaft, and a spring for the sliding body is loaded on the spring shaft on the rear end side of the through-hole. The spring is always given elasticity in the front end direction by the spring. The spring shaft and the through hole are configured to prevent the step-like sliding body from coming off and to extend and retract the sliding body spring.
[0009]
In addition, in order to make the front lower edge of the furniture higher than the floor and to tilt the furniture from the beginning to the back wall side, it is an inverted stepped fitting part on the lower surface of the furniture front lower edge fitting part of the lifting body It is also possible to install the overlapping bottom part, without setting up the lifting body, place the base part where the lifting body abuts in the depth direction of the board with a space in between, and the furniture front lower edge fitting part on it By placing the furniture, it is possible to raise the front lower edge fitting portion of the furniture and raise the front lower edge of the furniture to a height higher than the thickness of the base portion from the beginning. Furthermore, in order to lay an elastic plate integrally on the bottom side of the adhesive sheet on the bottom of the furniture front lower edge fitting part of the lifting body, and to lay the furniture front lower edge, An inverted stepped fitting portion overlapping bottom portion corresponding to the staircase of the stepped sliding body can be preliminarily worn and placed below the bottom surface of the fitting portion.
[0010]
[Embodiment of the Invention]
This will be described with reference to one embodiment shown in FIGS. The furniture front lower edge fitting portion 2 on the front side of the lifting body 1 on which the front lower edge of the furniture is mounted is normally placed on and brought into contact with the base portion 4 of the substrate 8 as shown in FIG. Inclined to the back wall at a small angle. When the furniture swings due to the vibration and the front side rises with the back side as a fulcrum, the furniture front lower edge fitting portion 2 that is bonded together rises as the furniture front lower edge rises, and a gap is formed between the furniture and the base portion. At the same time, the stair-like sliding body 12 moves in the direction of the furniture front lower edge fitting portion 2 on the front end side by the elasticity of the spring 16 for the sliding body acting in the front end direction, and the small width restoring portion 13 on the front end side is the substrate. The step-like sliding body 12 is inserted into the gap between the furniture front lower edge fitting portion 2 and the base portion 4 through the through hole 10 formed in the upward front plate 9 of 8.
[0011]
Therefore, the lower front edge of the furniture as shown in FIG. 6 in which the stepped surface is higher than the previously abutted surface according to the gap formed between the stepped sliding body 12 and the base 4 in accordance with the vibration. It is inserted in the lower side of the fitting part 2 and fixed with the front lower edge of the furniture raised, and the inclination to the wall side is increased. In other words, it acts when there is a greater vibration than the previous vibration, the inclination angle increases due to the vibration, and the inclination angle of the furniture is sequentially increased to prevent forward movement even for larger vibrations. At this time, the elevating body 1 is moved up and down integrally with the furniture front lower edge fitting portion 2 by the adhesive sheet 6, and the side plate 11 on the side surface portion of the substrate 8 serves as a guide for the stepped sliding body 12 and right and left slip-off prevention, A through hole 14 drilled in a part of the stepped sliding body 12 and a spring shaft 15 passing through the through hole 14 serve as a stopper for preventing the stepped sliding body 12 from coming off and an expansion / contraction guide for the sliding body spring 16.
[0012]
When the stepped sliding body 12 sequentially moves to the front end side, as illustrated in FIGS. 7 and 8, when the upward front plate 9 is provided on the front end side of the substrate 8, the stepped sliding body 12 protrudes from the front side of the stepped sliding body 12. Since the narrow restored portion 13 is exposed through the through hole 10 formed in the front plate 9 facing upward, the stair-like sliding body is formed by raising the front side of the furniture and pushing the narrow restored portion 13 after the end of the vibration. 12 can be restored to the normal state. Further, when the upward front plate 9 of the substrate 8 is omitted as illustrated in FIG. 9, it can be restored to a normal state by pushing in the wide restoring portion 18 protruding outside the substrate 8.
[0013]

[The invention's effect]
The present invention can be installed by simply inserting it into the lower front edge of the furniture without damaging the furniture, walls, pillars, etc. In the inclined state, when the vibration that the front side of the furniture rises arrives and the furniture swings and the front lower edge rises, the stepped sliding body is automatically moved by the elasticity of the sliding body spring. It moves forward and is inserted into the lower gap of the furniture front lower edge fitting portion. Accordingly, the stepped surface higher than before makes contact with the bottom surface of the furniture front lower edge fitting portion to automatically increase the inclination angle of the furniture. After that, each time there is a greater vibration than before and the front side of the furniture rises, the high staircase is inserted under the furniture front lower edge fitting part in sequence, so the inclination angle is gradually increased. By tilting the furniture to the back wall side, it is possible to prevent forward movement. In addition, it is extremely effective for disaster prevention because it can be easily restored to the normal state by simply pushing the restoration part after the vibration is finished.
