Description

  The present invention relates to a furniture overturn prevention device in which a ceiling is opened so that functions such as a lighting fixture and a ventilation port can be used together.

The conventional furniture fall prevention tool has no idea of opening and fixing the ceiling. This is because the main point is that it can be attached as easily as possible. Originally, the long-term effect of pressing down furniture cannot be maintained unless support is provided from a solid member such as a ceiling base.
However, the actual situation is that support is provided from a ceiling material that is not strong, such as a plasterboard or thin veneer, or a part of the table for holding the furniture fall prevention tool is hung on the ceiling support material.
(For example, refer to Patent Documents 1 and 2).
Although wood screws are driven into the walls and furniture, there are some fall prevention tools that are designed to prevent them from falling even if the flooring, such as tatami mats and carpets, is used for a long period of time, or when the ceiling is displaced during a major earthquake, but the furniture moves There is no consideration for scars.
(For example, refer to Patent Document 3).

Hereinafter, a conventional furniture overturn prevention tool will be described with reference to FIGS. In FIG. 10, reference numeral 101 denotes a stand for pressing the ceiling to fix the furniture, and it is considered so that it can be easily installed without damaging the ceiling. However, in the event of a major earthquake, aged deterioration such as plasterboard or thin veneer used as a ceiling material, the presser base 101 is good only on a part of the ceiling support material, the initial due to the subsidence of tatami mats and carpets, etc. Given the problems such as reduced pressing force, it is unlikely that the furniture will not fall.
In FIG. 11, 111 is a wood screw driven to fix a metal plate to a wall or furniture, and is assumed to be resistant to a large earthquake, but scars remain on the wall or the like when the furniture moves.
In addition, in the case of stacked furniture rather than the top and bottom integrated type, this method does not have a pressing force from above, so there may be cases where it will be damaged in the event of a major earthquake.

  As described above, there is no conventional furniture fall prevention tool that opens to the ceiling and is fixed to the ceiling, so that the ceiling material with weak strength is excessively pressed so that the presser base does not slip. It's hard to say that they are adequate. .

  However, in preparation for a major earthquake that you do not know when to come, even if you want to attach a firm furniture fall prevention tool that was originally fixed to the building as shown in Fig. 11 above, you may not be able to step it so far when you consider the movement of the furniture. Many. Therefore, there were many ideas of the structure as shown in FIG.

  In recent years, the number of do-it-yourself stores has increased, and tools that can be easily opened through the ceiling are available. It is not difficult to open the ceiling above the necessary furniture. With a structure that can be adjusted to an appropriate pressing force with a member that opens and fixed to the ceiling, a pad that is attached to the contact surface to the furniture, and a member that connects them, the conventional furniture fall prevention tool Not supposed to be.

  The furniture overturn prevention tool includes a member fixed to the ceiling, a length adjusting member, a connecting member with a screw, a spring, a pad, and the like, and has a structure that always presses the furniture down appropriately.

  The fixed point of the ceiling does not slide horizontally, and in the vertical direction, the above-mentioned spring is used to force the furniture down, so even if the tatami mat sinks for a long time, the spring or soft With a small pad, you can apply moderate pressure to the furniture and expect great effects even during a major earthquake.

  In addition, the present invention improves the performance as a furniture overturn prevention device as compared with the conventional one by making the portion opened as the furniture overturn prevention device a function of ventilation, downlight, emergency lighting, etc. There is a special feature in making it possible to use multifunctional functions.

  In addition, if the member fixed to the floor or beam on the upper floor and the member fixed to the ceiling as a furniture fall prevention tool are connected and connected in the ceiling, the floor material and beam on the upper floor and the furniture are consequently connected. It will be connected directly with furniture fall prevention equipment, and it will have a sufficient effect even in the event of a large earthquake.

  As described above, the furniture overturn prevention device of the present invention can add a function as a ventilation port, a lighting fixture, or a sensor to a member for opening and fixing the ceiling surface.

  Provide the above-mentioned purpose by providing an opening with an optimal size for the passage of wind and light in the connecting member with the ceiling without any problem in strength, and further, if the opening method does not hinder the reception of the sensor Can do.

  When attaching a fixture to a beam in the ceiling or a floor on the upper floor in the case of a new construction, etc., and connecting this to the ceiling opening fixing member, the furniture is fixed at a stronger place, which is the conventional technology In comparison, the strength can be dramatically increased.

  If connected to a connecting member in the ceiling having the function of a ventilation facility, it becomes a ventilation opening of a 24-hour ventilation facility that has already been legalized in a newly built house. In addition, if a lighting fixture is installed and a qualified electric construction shop is commissioned only for power supply wiring work, it can be used as a downlight or emergency lighting. In addition, an emergency alarm facility sensor already regulated in Tokyo can be attached to the ceiling fixing member.
