[Industrial applications]

 The present invention relates to a bed structure, and more particularly, to a bed that can be easily turned over naturally by a person who can not turn over, such as a bedridden old man, and can rest comfortably as if it were a cradle.

[0002]

[Prior art]

 Generally, the bed has a flat rectangular floor with a short side of 90 to 180 cm and a long side of 200 cm supported horizontally by four legs at a height of about 30 to 40 cm above the ground, and a head panel on the head side. It consists of a simple structure consisting of an iron pipe skeleton and floor boards or springs, as well as luxuriously decorated wooden ones.

Basically, the floor plate of the bed is a flat rectangular surface on which a mat, a bedding, etc. are placed, and it is fixed to the ground by legs arranged at the four corners.

In recent years, in consideration of the convenience of the sick person and the elderly, a bed has been developed which is electrically operated so that the height of the floor can be adjusted and the backrest is raised, and is used in hospitals and the like. There is.

[0005]

[Problems to be solved by the device]

 However, in the above-mentioned conventional bed, there is only the function of raising the backrest when moving out of the bed, raising the back part when eating, etc., adjusting the height of the bed, etc. to eliminate bed sickness that is easily caused by bedridden elderly people without turning over. The function has not been developed yet.

In addition, even a normal healthy person does not mean that his / her body is at rest during sleep, but if he / she sleeps in the same posture, the state of blood circulation becomes poor (congestion) and then unravels. It should be clear that the unconscious rolling motions performed in order to do so are repeated many times during the night.

Then, it is considered that the sleep becomes light due to the discomfort of congestion several times during sleep, and it is automatically performed even if it is not necessary to turn over to eliminate the congestion and bed sore. If you are told, you should be able to sleep deeply throughout your sleep.

The present invention has been made in view of the above circumstances, and provides a turning bed devised so that a cylinder-shaped floor surface that swings left and right at an arbitrary cycle can be turned over comfortably or automatically. It is a thing.

[0009]

[0014]

[Action]

 The turnover bed according to the present invention has a structure in which the bed surface serving as a bed is curved downward in a cylindrical shape and swings left and right at a predetermined set cycle by a motor, so that it is possible to sleep as if sleeping in a cradle.

Further, by adapting the half cycle of the left and right shaking to a time interval (for example, about 30 minutes) at which it is desired to roll over, even a bedridden elderly person who cannot roll over can easily roll over.

The swing cycle can be arbitrarily set by operating the electric system section, and the swing magnitude can be changed by adjusting the positions of the rotary link and the rod-like link.

The pillow portion is curved like the floor surface, and the head does not come off from the pillow portion even when hitting over.

Further, since it is integrated with the backrest portion, the pillow portion does not fall even when the backrest portion is raised when sitting on the bed.

Furthermore, if the floor of the bed is shaken greatly to the left and right, although there may be individual differences, some anxiety may be felt at the beginning of sleep, but the head side of the floor is 5 to 20 cm higher than the foot side. Maintaining a tilted position eliminates anxiety.

[Embodiment of device]

 DETAILED DESCRIPTION OF THE INVENTION An embodiment of a roll-over bed according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view of a turnover bed according to the present invention.

FIG. 2 is a view for explaining a swing slider link mechanism that causes left and right swings of the turning bed according to the present invention.

FIG. 3 is a perspective view for explaining the structures of the pillow portion and the backrest portion in the above-mentioned bed for turning over.

First, as shown in FIG. 1, the turnover bed 30 has fall prevention fences 1a and 1b arranged along the edge of the long side y, and a pipe 3 fixed at the center of the back surface in parallel with the long side and short. A cylindrical curved floor 5 whose side x is curved downward, columns 6a and 6b that pivotally support the floor so that the pipe 3 on the back surface can be rotated left and right, and a long side y of the floor 5. One end 8a is pivoted near the edge of the motor and the other end 8b is pivotally mounted on the floor 11 below the floor. A first feature is that the swing slider crank mechanism is configured and an electric system unit 15 that controls the rotation of the motor 11.

The floor surface 5 has a curved cross section along the short side x and forms a part of a circle (arc). The radius of the arc is the length of the short side x of the floor surface 5 and Although it depends on the degree of maximum inclination and the ease of sleeping, an apex angle of 60 to 45 degrees is suitable for the present invention within a range of approximately 80 cm or more and 2 m or less.

If the cover is less than 80 cm, the curvature is strong compared to the width of the bed and the shoulders are cramped, making it difficult to sleep. If the cover exceeds 2 m, the curvature is small and the floor becomes a substantially flat surface. If you tilt it to the left or right enough, you may get a lot of momentum and roll.

In this embodiment, the floor surface 5 has a size of about one tatami mat (single bed).

Next, the left and right swinging mechanism of the floor surface 5 in FIG. 2 will be described.

In the figure, (A) is a horizontal state, a disk-shaped rotary link 13 which is pivotally attached to the shaft of the gear box 12 arranged on the left side of the drawing and rotates about this as a node S1, The other end of the rod-shaped link 17 pivotally attached at the link 13 and the node S2 is pivotally attached at the node S3 near the edge of the long side of the floor surface 5.

In other words, a four-bar rotation mechanism is formed with the fixed pipe 3 as a node S4, and a swing slider crank mechanism in which the link between S4 and S1 is fixed is completed.

Therefore, when the rotary link 13 gradually rotates in the direction of the arrow, the floor surface 5 tilts to the leftmost at the time when the rotary link 13 and the rod-shaped link 17 overlap each other as shown in FIG. After about half a turn, the rotary link 13 and the rod-shaped link 17 are in the most extended state, and the floor surface 5 tilts to the right in the drawing.

When the rotary link 13 is slowly rotated in one direction at a constant speed, the swing slider crank mechanism causes the floor surface 5 to swing right and left at an appropriate cycle, so that the person sleeping is naturally lying on his back. Thus, the body leans to the left and right and rolls over to alleviate bed sores and congestion without consciously moving the body.

Not only is this good news for the bedridden old man who cannot be rolled over, but it also frees the caregiver from the trouble of heavy work overturning.

Also, for a healthy person, turning over naturally as if in a cradle is carried out, so that deep sleep is maintained.

Next, the turnover bed in FIG. 1 is placed on the floor so that the upper surface on which the head is placed is located at a position 3 to 15 cm higher than the floor 5 from one end to the other on the short side of the floor 5. The second feature is that the curved pillow portion 20 is also arranged.

One end of the pillow portion 20 is fixed by a hinge means 22 to a backrest portion 21 (metal plate) rotatably attached to the floor surface 5 and, together with this, a horizontal position of about 90 degrees. The third feature is that it can be raised and fixed by the locking mechanism of the support rod 24 within the range up to.

The backrest portion 21 and the pillow portion 20 will be further described with reference to FIG. 3. The pillow portion 20 is a curved wooden frame covered with a soft cloth such as felt and made of metal such as iron plate or stainless steel. It has a backrest made of steel (the surface where the pillow is attached to the pillow is curved) and a screw.

On the back side of the backrest portion 21, a support rod 24, which is inserted into a hole 25 formed at the end of the floor surface 5, is rotatably supported, and the shaft support portion 26 folds the pillow portion 20 to be horizontal. It is adapted to fit in the hole 25 in the state of being set.

The support rod 24 is provided with 2 to 10 protrusions 27 at appropriate intervals, and is engaged with the peripheral edge of the hole 25 to support the backrest portion 21 at an arbitrary angle.

Next, the electric system section 15 has a power source section, a timer circuit, a switch section, and a control circuit built in the box, and the rotation speed of the motor 11, in other words, the period of left and right shaking of the floor surface 5. Can be adjusted, and the shaking can be stopped at the desired time with a timer.

Since the electric circuit of the electric system section can use a conventional simple control circuit, the description thereof will be omitted.

The fall prevention fences 1a and 1b arranged on the left and right of the turning bed 30 are covered with a flexible material so that they do not hurt even if they collide with each other, and the electric system section 15 has a bedside. The grip switch is pulled up to the hand with a cord.

Further, the gear box 12 is transmitted and rotated by the motor 11 and the belt to slow down the rotation and increase the torque to firmly support the floor surface 5 via the rotary link 13 and the rod-shaped link 8 and to the left and right. Since it rocks, even if a large load is applied to the gearbox while a person is asleep, it will not turn over.

By the way, when using the above-mentioned turn-over bed 30, there is a possibility that some people may feel a little anxious about whether or not the bed may fall over, and the first time the person sleeps on the turn-over bed 30, it may not be able to fall asleep.

In this respect, maintaining the head side of the floor in a state of being inclined so that it is 5 to 20 cm higher than the foot side gives a mental relief because the brain is higher than the body. And the anxiety disappears. In this case, there is no fear that the body will fall off due to the height difference of about 5 to 20 cm.

Needless to say, the above-mentioned inclination can be easily realized by, for example, making the pillar (leg) on the head side slidable and adjusting the height with a thumbscrew or the like.

As described in detail above, despite the simple structure of the bed according to the present invention, the problem of bed sore of the bedridden old man, which has been a problem in the past, is solved, and even the general public automatically performs the operation of hitting the bed. It is an excellent idea that you can sleep deeply as if you were a baby sleeping in a cradle because it encourages you.

[0048]

[Effect of device]

 Since the turnover bed according to the present invention is constructed as described above, it has the following effects.

(1) It has an excellent effect that it automatically promotes a turning motion to prevent bed sores and congestion, and makes it possible to sleep deeply like a cradle.

(2) Since the backrest portion and the pillow portion can both be raised, it has an excellent effect of being able to easily sit on the bed floor.
