Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an improved bed suitable for use in hospitals, nursing homes, and the like.

[0002]

2. Description of the Related Art Conventionally, beds used in hospitals, nursing homes, and the like are often configured to be able to bend at two or three places around the left-right axis of a long bed plate in the front-rear direction. When the upper body takes a posture in which the upper body is raised or a posture in which the legs are bent, the bed board is bent. Usually, the bed board is used in a horizontal state. Sleeping in the same posture for a long time on a bed in a horizontal state causes bedsores, back and back pain, and if you cannot move, such as immediately after surgery, you will sleep in the same posture for a long time,
Similarly, there is a problem that the back and lower back are hurt. For this reason, it is necessary for the sleeping person to turn over himself or for a caregiver or the like to sometimes turn over.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a bed capable of alleviating bedsores, back and lower back pain even when sleeping in the same posture for a long time.

[0004]

In order to solve the above-mentioned problems, a bed according to the present invention has a rectangular bed plate long in the front-rear direction arranged on an upper portion of a support, and the bed of the bed is placed on the support. It is characterized in that a support member is provided for supporting the left and right center portions so as to be swingable about the longitudinal axis, and a swing device for swinging the bed plate at a predetermined angle about the axis is provided. Here, a fence may be provided upright on the left and right sides of the bed plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a side view thereof, and FIG.
FIG. 4 is a sectional view of a main part of the swinging device, and FIG. 5 is a sectional view corresponding to FIG. 3 showing another embodiment of the means for attaching the fence.

In the embodiment, the bed 1 comprises a support base 3 for supporting a rectangular bed plate 2 which is long in the front-rear direction so as to be able to swing in the left-right direction, and a swing device 4 for swinging the bed plate 2. The support base 3 of the bed plate 2 includes a pair of front legs 5a, 5
b (5) and a pair of rear legs 6a, 6b (6)
And the front legs 5a, 5b and the rear legs 6a, 6b
a, 7b (7), a support frame (support member) for horizontally connecting the pair of front legs 5a, 5b at a predetermined height.
A supporting frame (supporting member) 8b (8) that horizontally communicates a predetermined height (the same height as the supporting frame 8a) between the rear leg 8a (8) and the pair of rear legs 6a and 6b is provided. The bed plate 2 is disposed between the front leg 5 and the rear leg 6 in the front-rear direction, and a rotating shaft 9 is fixed in the front-rear direction to the left and right center portions of the lower surface of the bed plate 2, and both ends 9 a of the rotating shaft 9. , 9b provided on the front leg side and the rear leg side, respectively.
To be swingably supported. Then, the bed plate 2 is moved up and down by a predetermined angle α with respect to the horizontal plane A about the rotation axis 9.
A swing device 4 that swings at (about 10 to 15 °) is provided. Note that a mattress 10 and a futon are laid on the bed board 2.

The swinging device 4 shown in FIGS. 3 to 5 is based on a crank mechanism, and rotates a crank 12 about a crankshaft 11 to connect a connecting rod 13 to the left end or the right end of the lower surface of the bed plate 2. The crosshead 14 attached to the section is reciprocated in the vertical direction, and the bed plate 2 is swung about the rotation shaft 9. The shape and size of the crank 12, the mounting position of the crosshead 14, and the like are appropriately adjusted to adjust the vertical reciprocating movement distance, and thus the swing angle α of the bed plate 2. The driving force for the rotation of the crankshaft 11 is obtained from an electric motor (not shown) or the like. The rotation speed of the crank 12 is adjusted so that the swing cycle is about 5 to 10 minutes per cycle.
Note that the swing device 4 using the illustrated crank mechanism is an example, and it is a matter of course that another means such as another crank mechanism or a cam mechanism may be used.

If the bed plate 2 is swung right and left, the same effect as turning over can be obtained even if the user stays in the same posture on the bed 1 for a long time. In particular, when the swing angle α is about 10 to 15 ° in the vertical direction with respect to the horizontal plane A, and the swing cycle is about 5 to 10 minutes per cycle, the position where the load is applied changes appropriately. Therefore, an effect similar to that of turning over moderately is obtained, which is preferable.

Since the bed plate 2 is tilted left and right by swinging, a fence 15 is preferably provided upright on the left and right sides of the bed plate 2. 2 and 3, the support holes 16 are provided at a predetermined pitch on the upper surfaces of the horizontal frames 7a and 7b, and the lower ends of the support legs 15a of the fence 15 are fitted into the support holes 16 so that the fence 15 is mounted. Removably stand upright. FIG. 5 shows a structure in which fences 15 are provided on the left and right ends of the bed plate 2 so as to be detachably erected.
5 also moves. Thus, the fences 15 are provided on the left and right sides of the bed board 2.
When the bed plate 2 is inclined in the left-right direction,
Prevents the sleeping person from falling off the bed.

[0010]

As described above, according to the bed of the present invention, since the bed plate can swing about the center in the left-right direction about the axis in the front-rear direction, even if the user is lying in the same posture for a long time, he / she turns over. The same effect is obtained,
It can relieve back and back pain. Also,
If the fences are provided upright on the left and right sides of the bed board, it can be prevented from falling off the bed even when the bed board is tilted by swinging.
