[0001]

FIELD OF THE INVENTION The present invention relates to a floor of a house.

[0002]

2. Description of the Related Art Conventionally, the floor of a Japanese-style room does not have the ability to store items, and the items have been put in and taken out by using an attached closet or closet.

[0003]

The conventional Japanese-style room has the following drawbacks. (B) Putting futons in and out of the closet was a heavy burden for the elderly. (B) When the bed is installed, the available space becomes small, which is inconvenient. (C) Even when you want to use water when caring for the elderly,
It was difficult in a Japanese-style room. An object of the present invention is to solve these drawbacks and to provide a tatami bed for a Japanese room, which is particularly suitable for elderly people.

[0004]

[Means for Solving the Problems] A frame 2 is fixed under the floor of a tatami 1 in a Japanese-style room, and a floor 3 supported so as to be vertically movable relative to the frame 2 is provided, and the frame 3 is expanded and contracted between the frame 3 and the frame 2. A possible supporting device 4 is provided. A valve 6 and a pump 7 are connected to the support device 4 via a pipe 5.

[0005]

When the pump 6 is operated and then the valve 6 is operated to extend and contract the support device 4, the floor 3 moves up and down with respect to the Tatami 1 to the upper position, the same position, and the lower position.

[0006]

EXAMPLES Examples of the present invention will be described below. FIG.
Is a cross-sectional view of the floor portion of the Japanese-style room, a part of Tatami 1 is cut open to form an opening, and the frame 2 is fixed below the floor so that the opening is closed from below. The frame 2 is made of synthetic resin and is made so as not to leak water, and is provided with a drainage port 8 and a plug 9 at the bottom and is connected to a drainage pipe 10. The floor 3 that fits into the opening of the tatami 1 without a gap is one in which the tatami is fixed on a wooden base. Guide cylinders 11 are fixed to the four corners of the lower surface.
FIG. 2 is a plan sectional view of the frame body 2, and the guide tube 1 of FIG.
A guide hole 12 into which 1 is inserted is provided. Therefore, the floor 3 is guided vertically with respect to the frame 2. A support device 4 that extends in two stages is attached to a position where the frame 2 and the center of the floor 3 are vertically connected. A valve 6 and a pump 7 are connected to this through a pipe 5.

Since this embodiment is constructed as described above,
When the pump 7 is operated and the valve 6 is operated, the support device 4 expands and contracts and the floor 3 moves up and down. Therefore, as shown in FIG. 1, when the floor 3 is located above the tatami 1, it can be used as a bed, a desk, a step, or the like. Since the height can also be adjusted by operating the valve 6, it is possible to select a height that is easy for a caregiver to care for when using it as a bed, for example. Moreover, the effect of being able to wake up easily is also obtained. Further, instead of the tatami material fixed to the floor 3, if a cushioning material having a waterproof property is used and the height is set to a position lower than the tatami 1, the floor 3 becomes slightly sunk inside the frame body 2. . Therefore, the plug 9 is removed and the drain pipe 10
When you connect it to the floor 3, even if you pour hot water such as a shower on the floor 3,
The drainage collects in the lower part of the frame body 2 and is discharged from the drainage port 8, so that an effect of facilitating care is obtained. Pump 7
May be manual, and the fluid for expanding and contracting the supporting device 4 may be oil, water, air, or the like. In particular,
If air is used and an accumulator or the like is used, a cushioning effect can also be obtained.

Another embodiment will be described with reference to FIGS. 3 and 4. The lightweight tatami mat 14 is supported on the wall 13 of the Japanese-style room through the pin 15. With the floor 3 in the lower position of Tatami 1 in FIG. 1, rotate the lightweight Tatami 14 to the horizontal position,
It is held by a stopper 16 that can move in and out. Light weight 1
Since 4 is the same size as the floor 3, it serves as a cover for the opening of the Tatami 1. And the floor 3 is light weight 1
Can be hidden under 4. Therefore, bedding is kept on the floor 3 and is covered with the light-weight damage 14 in the daytime so that it cannot be seen. At night, the light-weight damage 14 is fixed to the wall 13 so that the floor 3 is located at the upper position. Becomes This eliminates the need for an elderly person to put in and take out the bedding from the closet, and an unexpected visitor can immediately hide the bedding and the toilet bowl on the floor 3.

FIG. 4 is an explanatory view showing an example of the light weight tatami mat 14. The inside of the tatami mat is filled with activated carbon between the honeycomb structure made of the reinforcing paper 17. Therefore, while being strong enough to withstand the weight of a human body or a desk, it is lightweight,
It also has a deodorizing effect. In addition to activated carbon, it is possible to mix a filler such as urethane. Further, in the state of FIG. 1, if a heating element such as a foot warmer or an electric blanket is arranged on the bottom of the frame body 2 and the floor 3 is covered with a kotatsu blanket, it can be used as a dug kotatsu. Alternatively, if the bottom of the frame 2 is filled with ice in the summer, it can be used as a simple storage and can be kept cool. The water coming out of the ice
If the plug 9 is removed, it will be discharged. It is also possible to connect ordinary domestic water supply to the pipe 5, and if the support device 4 is moved up and down by switching the valve 6, the pump 7 can be omitted.

FIG. 5 is a sectional view showing another embodiment. The frame 2 is fixed below the opening of the tatami 1 in the same manner as in FIG. 1, but as a supporting device that supports the floor 23 in a vertically movable manner, the cylinder 24 penetrates the four corners of the floor 23. Four are provided. At the top of the cylinder 24 is a table 25
Is installed, and by expanding and contracting the cylinder 24, it is possible to move up and down from the uppermost position in FIG. Like the floor 3 of FIG. 1, the floor 23 can be moved up and down from the upper position of FIG. 5 to the lower position lower than the level of Tatami 1. Therefore, in this embodiment, the floor 23 and the table 25 can be used as a bunk bed while the floor 23 and the table 25 are raised to the maximum as shown in FIG. 5, and the floor 23 can be used as a table or excavation kotatsu. However, the table 25 can also be used as an upper storage shelf.

Further, the floor 23 and the table 25 are lowered to the lowest position so that the table 25
If the floor 23 is located at a level lower than that of the Tatami 1, the table 25 will serve to cover the floor 23, so that, for example, bedding, toilet bowl, etc. are placed on the floor 23. Can be hidden. Since the upper surface of the table 25 can be used as a part of the Japanese-style room like the upper surface of the Tatami 1, there is an advantage that the Japanese-style room can be widely used.

In the cylinder 24, as in the case of the supporting device 4 in FIG. 1, a valve 6 and a pump 7 are connected via a pipe 5.
Needless to say, the cylinder 24 is expanded and contracted by the operation of the valve 6. It is also possible to fix the tampering material or the lightweight tampering 14 of FIG. 4 to one or both of the floor 23 and the table 25. Floor 2 using this weight difference
3 and the order of the vertical movement of the table 25 can be defined. For example, with the table 25 supported at the uppermost descending position, the floor 2
Only 3 can be raised or lowered.

If the table 25 is a bed provided with usual bedding and the floor 23 is provided with a waterproof cushioning material, the caregiver lays the elderly person on the table 25, and the caregiver puts it on the level of Tatami 1. Lower to Tatami 1 and then raise floor 23 to the level of Tatami 1 and place the elderly person by horizontal movement on this, and with this floor 23 slightly submerged, wash your body with a shower etc., After wiping with a towel, raise the floor 23 to the same level as Tatami 1 and then move horizontally onto Tatami 1, then lower table 25 to the same level as Tatami 1 and move the elderly person horizontally to this. Can be made. In other words, the body wipes that the caregiver needs the most effort,
The effect that only the horizontal movement of the elderly person can be performed using the shower can be obtained. Cylinder 24
Other equivalent means may be used as long as it is a support device that can move up and down, and a mechanical lifting mechanism such as a chain block may be used instead of fluid pressure.
