Description

  The present invention relates to an assembly-type seismic bed comprising a frame structure, a mat platform and a mattress.

  In Japan, where many earthquakes occur, there is a great demand for installing an earthquake-resistant mechanism. The same applies to bedding such as beds used in general households and ryokan facilities, and the trend has been increasing especially since the Great East Japan Earthquake that occurred in March 2011. The Tokyo Metropolitan Government also reviewed the “Assumption of damage to Tokyo caused by the earthquake directly below the capital” announced in May 2006 and published a new damage assumption in April 2012. Under the assumption, the Tokyo Bay Northern Earthquake (M7.3) was selected as the earthquake directly under the Tokyo metropolitan area that could cause major damage to Tokyo, and the scale of damage caused by this was calculated and assumed. Then, in Shinjuku alone, more than 3,600 mag is said to have the possibility of building collapse (total destruction).

  For this reason, the Tokyo Metropolitan Government intends to assist the earthquake-proofing of wooden houses under predetermined conditions, and the earthquake-proof shelter, earthquake-resistant bed, etc. are also symmetrical devices. However, all of the earthquake-resistant beds that have been developed so far are canopy-type mechanisms that cover the top, so that they have a high possibility of rollover in the event of a large roll.

  Therefore, the problem of the present invention is that it is possible to protect the user from the collapse of a house that may occur at the time of an earthquake disaster, the fall of a roof, a window glass, etc., and the rollover of a large roll is also possible. It is a low possibility to provide a prefabricated seismic bed.

  This problem is solved by the assembled seismic bed according to claim 1. In the assembly type bed according to the present invention, the frame structure includes a bottom frame, a leg frame, and a support frame. Each member of the frame structure is made of heavy steel to provide an earthquake resistant structure. Therefore, it is difficult to carry into the house in the assembled state. By making it an assembly type, it becomes possible to assemble each member after carrying it into the house.

  The bottom frame of the frame structure includes a pair of longitudinal bottom frames provided parallel to the bed longitudinal direction, a pair of transverse bottom frames provided perpendicular to the bed longitudinal direction, and the transverse bottom frame between the pair of transverse bottom frames. It consists of a central bottom frame that is provided on. Further, the leg frame includes a pair of longitudinal leg frames formed in an inverted U shape including two leg portions and one connecting portion connecting the leg portions, three leg portions and the leg portions. It consists of a pair of transverse leg frames formed in an M-shape consisting of one connecting part to be connected. In this case, the longitudinal leg frame is erected on the longitudinal bottom frame, and the transverse leg frame is erected on the transverse bottom frame. The longitudinal leg frame is provided with a notch structure for accommodating the support frame on a substantially extended line of the two legs of the longitudinal leg frame, and the support frame corresponds to the notch structure. The formed notch structure is provided, and the notch structure of the longitudinal leg frame and the notch structure of the support frame are brought into engagement with each other, so that the pair of longitudinal leg frames has two Connected by support frame. In addition, the transverse leg frame is provided with a notch structure for accommodating the support frame on substantially the extension line of the three legs of the transverse leg frame, and the support frame corresponds to the notch structure. A notch structure is formed so that the notch structure of the transverse leg frame and the notch structure of the support frame are engaged with each other. Connected by two support frames. A mat platform is placed on the support surface formed by these support frames, and the mattress is accommodated in the mat platform.

  As a result, a large space for accommodating several adults is secured under the support frame of the earthquake-resistant bed. Further, due to the structure of the frame structure according to the present invention, the assembling-type seismic bed according to the present invention has an extremely high pressure strength.

  In an advantageous embodiment of the invention, the mat platform is formed as a box-shaped mattress housing structure comprising a bottom surface and three upstanding surfaces that are erected in a direction perpendicular to the bottom surface. This makes it possible to easily place the mattress on the mat platform, and after the mattress is accommodated on the mat platform, the mattress does not shift or move on the mat platform, and its position is Stable on the mat platform.

  In an advantageous embodiment of the invention, holes are provided in the longitudinal bottom frame and the transverse bottom frame, corresponding to the holes in the legs of the longitudinal leg frame and the legs of the transverse leg frame. Protruding portions are provided. This makes it very easy to stand the leg frame on the bottom frame, and the seismic bed according to the invention can be easily assembled. Moreover, the assembled seismic bed has sufficient strength.

  In an advantageous embodiment of the invention, guide plates are provided at both ends of the support frame for guiding the engagement of the notches of each support frame with the notches of each leg frame. Since the support frame, particularly the longitudinal support frame, has a considerable length, the ease of assembly is improved by providing a guide plate.
