In accordance with this, the bottom members 3, 3.
Is tensioned, and the gap Y between the bottom end rollers 2, 2 is adjusted.
(Intervals through which the rugs A and B can pass) are formed and set. Then, the rear end of the rug (for example, mattress) A that is already in use is dropped into the gap Y, and the rear end of the new rug B placed on the shelf 10 is moved from the gap Y to the position of the bed apparatus 1. Take out on the floor and upper foot frame 6
Temporarily fix to a.

Next, the bridge 11 is placed between the rug A in use and the new rug B (see FIG. 2). As shown in FIG. 7, the bridge 11 is composed of rotatable large and small rollers. A belt 11b is stretched between two small rollers 11a, 11a, and a large roller 11c is applied to the lower surface of the belt 11b. It is a length that can be bridged in the left-right direction of the bed device 1. The large-sized roller 11c has a cut-out central portion, and is formed so that no dirt adheres to the roller 11c due to contact with the rug A in use.

The drive handle 29 is provided in the recess 27 b of the drive attachment member 27 of the bottom end roller 2.
(See FIG. 6) and by rotating it,
The bottom end rollers 2 and 2 move forward while maintaining the set interval.

More specifically, when the driver mounting member 27 is rotated, the driving gear 28 formed integrally with the driver mounting member 27 is rotated, whereby the driven gear 25 is rotated. The driven gear 25 is formed integrally with the driving gear 24, and the driving gear 24 rotates with the rotation of the driven gear 25. Thus, the drive gear 24 moves forward on the rack 7c provided on the upper side frame 7a, and accordingly, the bottom end roller 2 moves forward (see the arrow in FIG. 8).

When the bottom end roller 2 moves forward, the bottom members 3 forming the floor portion of the bed device 1 are sequentially fed downward from the front end of the floor portion, and new floor portions are sequentially fed from the rear end. Are successively sent out (see arrows in FIG. 2).

On the other hand, in parallel with this, by moving the bottom end rollers 2 and 2 forward at a set interval, the rear end of the rug A is sequentially dropped downward, and the rear end of the rug B is successively newly formed. Is pushed up and placed on the floor portion formed in.

When the bottom end rollers 2 and 2 are moved to the front end of the bed apparatus 1 in this manner, the rug A in use is stored in the shelf 10 and the new rug B is placed on the floor. The replacement of the rugs A and B is completed (FIG. 3 shows a state immediately before the completion).

It is reduced in the front-rear direction by the slide mechanism (see FIG. 9).

Thereafter, the excrement is stored in the simple toilet D.

The bed device 1 according to the present invention can be appropriately designed and changed. For example, a roller-shaped member is preferably used for the configuration of the floor portion of the bed device 1. However, the present invention is not limited to this, and a sliding member having a small objective frictional resistance may be used.

When replacing the rug, a mattress is usually used as the new rug B. Alternatively, a new rug B may be used before the air is injected into the pneumatic temporary bathtub (commonly referred to as "air bath"). In the case of using the pneumatic temporary bath tub, after replacement, the patient is automatically positioned in the bath tub by injecting air, and it is naturally possible to return to the mattress from the bath tub in the reverse stroke. .

[0038]

According to the bed apparatus of the present invention, various effects as listed below can be obtained.

(1) A bed device in which a floor portion is formed by bridging a rod on a part of a frame, wherein the rod is interconnected with an adjacent rod, and the connected rod is End portions are provided at both front and rear ends of the body, and a gap having an arbitrary width can be provided between the front and rear end portions, and the connected rod-shaped body and the end portion can be moved in the front and rear direction, respectively. Thus, the patient on the floor portion is not moved at all, and therefore, the patient can automatically exchange a new mattress or the like with a mattress or the like in use without any self-help effort.

That is, the upper head and the foot frame are moved upward to form a gap between the two end portions, the rear end of the rug being used is dropped into the gap, and the floor portion of the bed apparatus is previously formed. The rear end of a new rug, which has been placed underneath, is temporarily fastened from the gap to the foot frame on the floor portion, and then the two ends are moved forward with the gap. This allows the in-use rug to move underneath the floor, the new rug to move onto the floor, and the patient to remain stationary.

In the same manner as described above, the patient is laid in a bathtub such as an "air bath" or the like, that is, the bathtub is replaced with a bathtub instead of a new one, so that the patient can take a bath or wash his hair. It has the effect of facilitating and greatly reducing the mental and physical burden on patients and caregivers. In addition, since the whole floor member is a roller that can be freely rotated, it is easy to transfer the patient to another device together with the rug, and it is easy to cope with prevention of bedridden of the patient and treatment in other places. .

(2) According to the second aspect of the present invention, since the upper rail can be bent from the set position and the lower rail can be extended and contracted, the bottom member of the portion which comes into contact with the patient's back is provided. Can be tilted upward from the set position, and the bottom member, which is the portion that contacts the patient's foot, can be tilted downward (has a gatch function).

Thus, not only is it convenient to view television and garden trees and landscapes, and to eat and read using a simple table (not shown), but also to install a simple toilet bowl on the lower frame. Thus, excrement can be treated without lowering the patient from the bed device.

(3) According to the third aspect of the present invention, when replacing the rug of the patient, a bridge is interposed between the rug in use and the new rug, thereby forming a concave shape caused by the replacement of the rug. Depression can be eliminated.

That is, in the bridge, the belt is hung around two rod-shaped rotating bodies, and further rotating bodies are in contact with the left and right ends of the lower surface of the belt, thereby closing the concave depression. Since both the rod-shaped rotator and the rotator rotate with the movement of the bottom end roller, the bridge moves forward with the movement of the concave depression so that the patient does not feel depression.

(4) As described above, according to the present invention,
From the hygiene aspect of medical treatment, including prevention of bedsores, to the advanced aspects of nursing care technology that does not make you bedridden, the content of the entire mass of medical treatment and nursing care can be enhanced in a labor-saving and rational manner.

Furthermore, compared with the conventional bed apparatus, it is possible to make the size, weight, and cost significantly smaller than those of the conventional bed apparatus. It is possible to provide a bed device that can meet social demands due to the increase of elderly people in the near future.
