However, the conventional fall prevention device 1 for furniture or the like may have the following problems. Since the furniture 5 is placed on the wall side (not shown) in some cases, the upper surface 5a and the ceiling surface 6a may not be parallel. In such a case, a gap is formed near the front and rear ends between the base member 3 of the fall prevention device 1 and the top surface 5a of the furniture or the like 5 or between the base member 4 and the ceiling surface 6a. May not be obtained and may not be able to withstand a large earthquake. It is conceivable to increase the tension force of the fall prevention device 1 in advance so as to prevent this gap from being generated, but it is necessary to apply unnecessary load to the furniture 5, the ceiling 6, and the fall prevention device 1. Therefore, the strength of the furniture 5, the ceiling 6, and the fall prevention device 1 is reduced by that much, which is not preferable. When vibrating due to an earthquake or the like, the column member 2 of the fall prevention device 1
Large bending moment is generated at both ends of the. for that reason,
The fall prevention device 1 may not be able to withstand a large earthquake or the like, because the column member 2 is deformed and sufficient tenacity is not obtained.

Therefore, in the case of a large earthquake or the like, the front and rear ends of the base members 3 and 4 may swing greatly, breaking through the upper surface 5a and the ceiling surface 6a of the furniture 5 and the furniture 5 may fall. Since the depth prevention device 1 has a limited depth dimension A of the base members 3 and 4, the upper surface 5a and the ceiling surface 6a of the furniture 5 and the like are provided.
May come into contact with weak parts. for that reason,
In case of a large earthquake, the base members 3 and 4 are
Of the upper surface 5a and the ceiling surface 6a may be pierced, and the furniture 5 may fall.

In order to solve the above-mentioned problem, the present invention is directed to a fall prevention device for furniture and the like which can be sufficiently strung between the furniture and the ceiling even if the furniture or the like shakes due to a large earthquake or the like. For the purpose of providing.

As described in detail above, the fall prevention device for furniture and the like according to the present invention has the following excellent effects. Claim 1
Even if the upper surface and the ceiling surface of the furniture and the like to be arranged are not parallel, the present invention described above adjusts the expansion and contraction of each of the two pillar members so that the base and the upper surface of the furniture and the like can be attached to each base member. Since the members can be brought into contact with each other, even if furniture or the like shakes due to a large earthquake or the like, the furniture and the like are sufficiently strung between the ceiling and the furniture, and the furniture and the like do not fall. In the present invention, since each base member is supported at two points by two pillar members, the bending moment generated in each pillar member is drastically reduced, and the deflection at both ends of each base member is significantly increased. Thus, even if furniture or the like shakes due to a large earthquake or the like, the furniture or the like is sufficiently strung between the ceiling and the ceiling, and the furniture and the like do not fall.

Further, according to the first aspect of the present invention, the abutment surface of each base member is provided at a location where the strength of the top surface or ceiling surface of furniture or the like is strong by adjusting the expansion and contraction of the end portion of each base member. Since the furniture and the like can shake due to a large earthquake or the like, the furniture and the ceiling are sufficiently strung between the furniture and the ceiling, and the furniture and the like do not fall. According to the second aspect of the present invention, by attaching and detaching the extension member to the end of each base member, the contact surface of each extension member is brought into contact with a strong part of the upper surface or ceiling surface of furniture or the like. Therefore, even if the furniture or the like shakes due to a large earthquake or the like, the furniture and the like are sufficiently stuck between the ceiling and the furniture and the furniture and the like do not fall.

According to a third aspect of the present invention, the base member can be extended and contracted between the portions where the two column members of the base member are joined, so that each base member can be placed at a location where the strength of the top surface or ceiling surface of furniture or the like is strong. Since the contact surfaces of the members can be brought into contact with each other, even if the furniture or the like shakes due to a large earthquake or the like, the furniture or the like is sufficiently strung between the furniture and the ceiling and the furniture or the like does not fall.
According to the fourth aspect of the present invention, since the structure has a strong strength, even if the furniture or the like shakes due to a large earthquake or the like, the furniture or the like can be sufficiently struck between the furniture and the ceiling, and the furniture and the like can be overturned. Absent.
