Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a bed convenient for use for a sick person who has been sleeping for a long period of time.

(Prior art and its problems) Conventionally, there are beds for long-term hospitalized patients or bedridden patients in which only the backrest part tilts up and down, but when dressing the patient, etc. The nurses had to carry out the work while at the same time, and the nurses were forced to do extremely hard labor.

In addition, patients themselves have disadvantages such as being prone to bedsores and getting tired easily.

(Means for Solving the Problems) The present invention has been researched to solve the above-mentioned drawbacks of conventional beds, and includes not only the inclination of the backrest but also the bending of the leg rest and the inclination of the sides of the bed. The aim is to provide a comfortable bed that allows the patient to change clothes freely, prevents bedsores, and prevents fatigue.

To describe the present invention in detail with reference to the illustrated embodiment, a movable plate 3 on a bottom plate 2 of a bed body 1,
It consists of locking mechanisms 4.4', 4', 4'', which are fixed to The seat is also divided into three parts, and a backrest part 7 that can be tilted upwardly and a legrest part 8 that can be bent upwardly are formed by hinges 6, 6, . . . .

The lock mechanism 4.4'... has a lock hole 15 fixed to the bottom plate 2, a lock rod 16 that can be moved in and out of this lock hole 15, a solenoid mechanism 17 that makes this lock rod 16 go in and out, and fixed to the movable plate 4. Latching protrusion 1 attached via hinge 18
9, the locking protrusion 19 can be freely inserted into the locking hole 15, and the tip entry portion 22 of the locking rod 16 can be freely inserted into the locking groove 20 of the locking protrusion 19. . One mounting plate 21 of the fixed hinge 18 is fixed to a latch projection 19. In the figure, 23 is a spring.

This locking mechanism 4.4'... is a first divided part 9 and a third divided part 11 on both sides of the second divided part 10 in the footrest part 8.
At the bottom plate 2 positions corresponding to the side edges of each backrest part 7 side and the side edges of the first back division part 12 and third back division part 1.4 on both sides of the second back division part 13 in the backrest part 7. However, the other mounting plate 21' of the fixed hinge 18 is fixed to the side edge of the movable plate mentioned above, and the lock hole 15, lock rod 16, solenoid mechanism 7, etc. are fixed to the bottom plate side.

Solenoid mechanism 17 in lock mechanism 4.4'...
is operated by a control panel (not shown).

The air bag mechanism 5 includes a pair of overlapping air bags 24 .
24' and a supply/exhaust mechanism 25 such as a compressor, the base end of the upper air bag 24 is fixed at a position near the base end of the second back division part 13, and the lower air bag 24' is fixed at the fixed position of the upper air bag 24. The base plate 2 is fixed at the position corresponding to the base plate 2. Furthermore, air bag 2
4 repeatedly expands and contracts, so only one end is fixed at an arbitrary location. Further, the number of air bags 24, 24' may be - or two or more.

The sending/exhausting mechanism 25 is the locking mechanism 4.4'.

It is designed to operate in conjunction with control panels 4' and 4''' (not shown).

In the figure, reference numeral 26 denotes an auxiliary air bag which bends the footrest part 8 and is designed to supply air in conjunction with the above-mentioned supply/exhaust mechanism 25.

27 is a string that limits the inclination of the backrest portion 7.

(Function) The present invention is embodied as described above, and to use it, first a mat, bedding, etc. is laid on the movable plate 3, and after the sick person is laid down, the control panel (not shown) is operated. , movable plate 3
When the locking rod 16 is in a flat state, the locking rod 16 is engaged with the latching groove 20 of the latching protrusion 19. In order to lift the upper part of the body, the locking mechanism 4 of the first back division part 12 and the third back division part 14 is used.
．． 4' is released and the air bags 24 and 24 are filled with air, and the backrest 7 is lifted as shown in FIG. 2, and when it is tilted at a predetermined angle, it is stopped and raised.

In addition, when changing the patient's clothes, for example, when the patient has to stand up on the right side, the locking mechanism 4', 4''' of the first dividing section 9 and the first back dividing section 12 and the solenoid mechanism 17 are used.
After the locking protrusion 19 and the locking rod 16 are unlatched by actuating, air is supplied to the air bags 24 and 24' between the backrest portion 7 and the bottom plate 2. Due to this air pressure, the second back division 4# and the third division 11 of the footrest 8 are prevented from being lifted up by the lock mechanism 4.4', but the rest of the backrest 7 and the footrest 1d are The portion 8 is gradually lifted up as the air bladders 24, 24' are filled with air, causing the human body to lie down as shown in FIG.

In order to lift the foot, the auxiliary air bladder 26 of the footrest 8 may be filled with air.

Furthermore, by operating the control panel, various lock mechanisms 4゜4',
4', 4''' and the air bags 24 and 24' are automatically and repeatedly supplied and exhausted, so that the movement is like turning over and is comfortable.

In order to flatten it, the air can be evacuated by operating a control panel or an exhaust plug (not shown).

Incidentally, air from the air supply/exhaust mechanism 25 can be blown onto the futon to cool the futon during hot weather, so that the user can have a comfortable sleep.

(Effects) As described above, the present invention consists of a movable plate on the bottom plate of the bed body, a locking mechanism that fixes the movable plate to the bottom plate, and an air bag mechanism disposed between the movable plate and the bottom plate. The long direction is divided into three parts, and the short direction is also divided into three parts to form a backrest part that can be tilted upwards by a hinge and a footrest part that can be bent upwards, and the locking mechanism is in the footrest part. arranged on the side edges of each of the first and third divided parts on the backrest side, and on the side edges of the first and third back divided parts on both sides of the second back divided part of the backrest. Each of the air bags can be fixed to the bottom plate, and the air bag mechanism consists of a single air bag or a stack of multiple air bags placed on the second back division of the backrest or the corresponding bottom plate position, and an air supply/exhaust mechanism. Because of this, the overall thickness can be reduced,
It can be used as is by placing it on an existing bed, and since it has a simple mechanism, it is easy to operate and does not break down.

Furthermore, the most important feature is that when the backrest is tilted or the backrest and footrest are tilted, two points in the locking mechanism are always locked.

As a result, the locked part remains flat and does not move, and the air bags are placed singly or in multiple stacks at the second back division or the corresponding bottom plate position. , the air filled in the air bag moves to the side opposite to the locked side and is filled, creating a smooth slope and slope.

The sick person on the futon laid out in this way can raise his or her upper body, bend and stretch one leg, and turn his or her legs to the side, making it seem as if he is tossing and turning, so he is less likely to get bedsores and is less fatigued. It has the advantage of being easy to carry out, since it requires less weight and can be done without any weight being applied when changing clothes.
