DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed apparatus capable of reliably protecting itself from an earthquake even when the user is sleeping on the bed body even if an earthquake occurs.

[0002]

2. Description of the Related Art After the disaster, a bed b as shown in FIG. 4 has recently been proposed. That is, the bed b was provided with a bed body a and a shelter section c provided below the bed body a. Also, this shelter part c
When it is not normally used, it has been covered (so as not to be seen from the outside) at covering portions d, d (such as a curtain). And when sleeping in this bed body a,
In the event of an earthquake, the structure is such that the covering parts d, d are once opened and then sheltered in the shelter part c to evacuate.

[0003]

However, if the magnitude of the earthquake was large, it was actually difficult to evacuate from the bed body a to the shelter section c. Also,
The movement from the bed body a to the shelter c was extremely dangerous, especially for elderly people, young children, and people with physical disabilities.

Therefore, the present invention solves the above-mentioned disadvantages, and it is not necessary to evacuate to another place even if there is an earthquake while sleeping on the bed itself, and it is possible to reliably protect yourself from this earthquake on the spot. It is an object of the present invention to provide a bed device capable of performing the following.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments.

FIG. 1 shows a bed apparatus according to the present invention. The bed apparatus includes a bed body 1 and a protective frame 3 with a ceiling 2 surrounding the bed body 1 from above. Sometimes effective. The protection frame portion 3 has a plurality of pillar portions 4 (four in the illustrated example) arranged in a vertically upright shape. The pillar portion 4 includes an outer cylinder portion 7 to which the bed body 1 is fixed, and an inner cylinder portion 8 which is suspended from the ceiling portion 2 and inserted into the outer cylinder portion 7 from above. Ceiling 2
Is a single flat plate as is clear from FIG.

The bed body 1 has four corners fixed to the outer cylinders 7 and supported by the pillars 4. Also,
At the upper part and the lower part of the outer cylinder part 7 (of the pillar part 4), an outer cylinder part connecting member 6 for connecting the outer cylinder part 7 (in a vertically upright shape) is provided horizontally. Have been.

Further, as shown in FIG. 2, the inner cylinder portion 8 has an outer flange portion 13 at a lower portion. And the outer cylinder part 7 has the horizontal wall part 11 in the lower part. The horizontal wall portion 11 is provided with a through hole 14 so that a lower portion of the inner cylindrical portion 8 (specifically, a portion below the outer flange portion 13) can be inserted therethrough.

Further, the outer cylinder portion 7 has a horizontal support portion 15 at a position below the horizontal wall portion 11, and a cushion material 16 (such as a rubber piece) is fixed to an upper surface of the horizontal support portion 15. ing. The cushion member 16 is attached to the horizontal support portion 15 at a position where the lower end of the inner cylindrical portion 8 comes into contact.

An impact absorbing portion 9 made of a retractable compression coil spring is interposed between the inner cylinder portion 8 and the outer cylinder portion 7 at a lower position. Specifically, the shock absorbing portion 9 is interposed between the outer flange portion 13 (of the inner cylindrical portion 8) and the horizontal wall portion 11. In addition, a hydraulic cylinder, an air cushion (gas spring), or the like may be used as the shock absorbing unit 9 in addition to the above-described coil spring.

Next, the state of the bed device during an earthquake will be described. First, as shown in FIG. 2A, it is assumed that an earthquake has occurred while sleeping on the bed body 1. At this time, an impact force F is applied to the ceiling portion 2 (of the protective frame portion 3) by a falling object (such as a lighting fixture or an interior decoration) or a falling object (such as furniture) due to an earthquake not shown.

Then, at this impact force F, FIG.
As shown in FIG.
The shock absorbing portions 9 (interposed between the outer flange portions 13 of the inner cylinder portions 8 and the horizontal wall portions 11) are compressed, and descend inside the outer cylinder portions 7. At this stage, the impact force F is absorbed by the impact absorbing portions 9.

Further, the lower end of the inner cylindrical portion 8 is a cushion material.
16, so that the load on the shock absorbers 9 due to the impact force F is reduced. Therefore, the shock absorbing portions 9 are hardly broken.

Therefore, even if an earthquake occurs while sleeping on the bed body 1, the ceiling 2 reliably protects the user from falling objects and falling objects. Furthermore, ceiling part 2
.. Only the inner cylinder portions 8... Fall down. That is, since the impact force F is irrelevant to the outer cylinder portion 7, the bed main body 1 is removed from the outer cylinder portions 7 of the protection frame 3. (Without separation) remains firmly fixed to the outer cylinder portions 7. For this reason, there is no fear that a sleeping person falls down from the bed main body 1, so that shelter can be performed while staying in the bed main body 1, and it is extremely safe.

Although not shown, a horizontal wall portion having a through hole through which the inner cylindrical portion 8 is inserted is provided at a substantially intermediate position inside the outer cylindrical portion 7, and the inner cylindrical portion 8 is located above the horizontal wall portion. It is also preferable to provide an outer flange portion and to interpose an impact absorbing portion 9 (such as a compression coil spring) between the horizontal wall portion and the outer flange portion.
No.

[0018]

According to the present invention, the following significant effects can be obtained by the above-described structure.

According to claim 1, an impact force F applied to the ceiling 2 by a falling object or a falling object due to an earthquake is:
It is absorbed by the shock absorbing portions 9 (provided on the column portions 4). Therefore, the bed device can surely withstand the impact force F.

In the event of an earthquake, the user is protected from falling objects and falling objects on the ceiling portion 2 while staying in the bed body 1 (without leaving the bed body 1), and is safe. In addition, this bed apparatus is extremely effective especially for elderly people, young children and people with physical disabilities. Also, protection frame
The column body 4 that constitutes the section 3 is fixed to the bed body 1.
The inner cylinder part 8 that is suspended from the ceiling part 2 to the outer cylinder part 7.
This bed is easily formed by simply inserting from
The device can be manufactured easily and quickly.

Further, since the bed body 1 is fixed to the outer cylinders 7 (of the pillars 4), even if an earthquake occurs, the bed body 1 and the protection frame 3 are always held integrally. Is done. Therefore, since there is no possibility of such roll off the sleeping person from the bed body 1, Ru can be evacuated from a very safely earthquake be left was the bed body 1 Nii.

(According to claim 2) Since the shock absorbing portion 9 is formed of a compression coil spring, the shock absorbing portion 9
It is possible to reliably absorb the impact force F given by a falling object or a falling object due to an earthquake, and to sufficiently withstand the impact force F.
