DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a perspective view of the body position maintaining device 1. As shown in FIG. 1, the body position maintaining device 1 is a bed 10 serving as a support device, and is arranged on the bed 10 to maintain a changed body position and a changed body position. Airbag 20 that functions like
To 23 and the supply / deaeration means 30 (see FIG. 2). The bed 10 is provided with both side plates 12.
And a floor plate 13 provided at an intermediate portion of the side plate 12 in the vertical direction.
And a mat 14 arranged on the floor plate 13 of the bed body 11 and constituting an arrangement surface.
It is composed of

Each of the air bags 20 to 23 has the same structure, and is formed of an airtight soft thin film member, and has a supply and deaeration port 25 (see FIG. 2). And a small spherical body 26 made of a synthetic resin or the like sealed in the inside. In addition, it is desirable that the granular material 26 has a buffering property because it can soften the contact with the body.

When the granular material 26 is inflated by supplying air into the bag 24 of the airbags 20 to 23 (hereinafter, the bag is simply referred to as an airbag), the airbag is inflated. It is in a free state in which it can move in the space in the airbags 20 to 23, and when forced exhaustion of air in the airbags 20 to 23, that is, deaeration is started, the airbags 20 to 23 are in close contact with each other as the deaeration proceeds. It becomes a solid state as a whole.

[0013] Therefore, the air bag 20
When deaeration is started with the body lying on the body 23, the surface supporting the body of the airbags 20 to 23, that is, the support surface is deformed along the skin surface, that is, the outer shape of the body according to the weight, The body sinks into the support surface, and a concave portion is formed in the support surface along the outer shape of the sinking body, that is, the concave portion has the same shape as the outer shape.

Further, as the deaeration progresses, the granular bodies 26 gradually come into close contact with each other. In this process, the body sinks on the supporting surface, and the air bag 20
The close contact state progresses along the inner peripheral surface of the concave portion formed on the support surface of Nos. 23 to 23, and the granular material 26 is solidified along the external shape of the body.

That is, when the granular material 26 is solidified along the outer shape of the body, the air bag 20
On the surface supporting the body, the same shape as that of the body formed when the body sinks is formed, and this recess is maintained until the air release of the airbags 20 to 23 is released. Is what is done.

A pillow 15 is placed on one side (the right side in FIG. 1) of the bed 10, and the airbags 20 and 21 of the airbags 20 to 23 are placed on the left side of the bed 10 (use Along the left side of the body when the person is lying on his back)
2 and 23 are located along the right side. That is,
The airbags 20 and 21 and the airbags 22 and 23 are arranged in two rows on the mat 14, that is, the arrangement surface of the bed 10.

Although not shown, the air bags 20, 21 and the air bags 22, 23 are provided with connecting means made of hooks or strips of magic tape on the lower surfaces thereof. A coupling means such as a hook or a velcro is also provided on the upper surface.
Are connected by both connecting means when they are arranged in two rows, so that they do not move with respect to the mat 14 during supply and deaeration.

On the lower side of the floor plate 13 of the bed body 10, the supply / degassing means 30, which is not shown but is composed of a pump having a supply / exhaust function, is disposed. Air is supplied to and removed from the airbags 20 to 23 via FIG. 2 (not shown in FIG. 1).

Next, the control configuration of the body maintenance device 1 will be described with reference to the block diagram of FIG. As shown in FIG. 2, the supply / desorption means 30 is composed of a first supply / desorption means 31 to a fourth supply / desorption means 34, and is provided with a first supply / desorption means 31 to a fourth supply / desorption means. One end of a hose 40 to a hose 43 is connected to the deaerator 34, and the other end of the hose 40 to the hose 43 is connected to the air bag 20 to the air bag 23, respectively.

The first air supply / desorption means 31 to the fourth air supply / desorption means 34 are controlled by a control means 35 comprising a microcomputer or the like. Is connected to an input means 36 such as a remote control device. The input means 36 is used to set a direction setting switch for turning the body upward, rightward and leftward, and an airbag 20.
To 23 are provided with various control switches (all not shown) such as an air supply adjustment switch and an air supply adjustment switch for adjusting the air supply amount.

The first air supply / desorption means 31 to the fourth air supply / desorption means 34 also function as maintenance means for maintaining the degassed or air-supplied state of the air bags 20 to 23. Is what it is. This maintaining means is provided by the first supply / desorption means 31 to the fourth supply / desorption means 34.
Instead of having the function, each of the hoses 40 to 43 is provided with an electromagnetic valve, and is constituted by these electromagnetic valves, and these electromagnetic valves are controlled by the control means 35 to supply and discharge air. The air bags 20 to 23, that is, the air bags 20 to 23, that is, the respective bag bodies 24 may be maintained in a degassed or air-supplied state.

Next, the operation when the body position maintaining apparatus 1 configured as described above is maintained in a body position will be described. First, the case where the body is maintained in a horizontal state will be described.
In the following description, it is assumed that the user, that is, the person lying on the bed, is lying on the airbags 20 to 23 in a supine position. To keep the body horizontal, the upward switch is closed. When the upward switch is operated, the control means 35 operates the first air supply / desorption means 31 to the fourth air supply / desorption means 34 to supply the air bags 20 to 23 with a predetermined amount of air, that is, a left air supply. Air bags 20 and 21 and right air bag 22
After the supply of an amount such that the upper surfaces of the and 23 are substantially flush with each other and are substantially horizontal, the first supply and deaeration means 31 to the fourth supply and deaeration means 34 are stopped.

When the first supply / desorption means 31 to the fourth supply / desorption means 34 are stopped, the supply and exhaust of the first supply / desorption means 31 to the fourth supply / desorption means 34 are stopped. Due to the function of stopping, air bags 20 to 23 (in FIG. 3, air bags 21 and 2 are shown) as shown in FIG.
3 only), the air is maintained in a state where the predetermined amount of air is supplied, that is, in a horizontal state.
It is kept horizontal on the upper surface of 0 to 23.

In a state in which the predetermined amount of air is supplied to each of the air bags 20 to 23, each of the air bags 20 to 23 has an appropriate cushioning action. Note that the degree of the cushioning action varies depending on the supply amount of air supply.

Next, to maintain the body in the rightward position, the rightward switch (not shown) is closed in the state shown in FIG. When this rightward switch is operated, the control means 35 operates the first supply / desorption means 31 and the second supply / desorption means 32 to supply air to the air bags 20 and 21 disposed on the left side. At the same time, in synchronism with the air supply operation to the air bags 20 and 21, the third air supply / deaeration means 33 and the fourth air supply / deaeration means 33 deaerate the air in the right air bags 22 and 23. The deaerator 34 is operated. That is, by the above control, the air in the right air bags 22 and 23 is deaerated, and the left air bags 20 and 21 are supplied with air.

That is, the right air bags 22 and 2
The air in the air bag 2 is supplied to the left air bags 20 and 21 while the air in the air bag 3 is deaerated.
The airbags 2 and 23 gradually contract with degassing, the airbags 20 and 21 gradually inflate with air supply, and the user's body gradually rotates rightward.

Then, the right air bags 22 and 23
Due to the weight of the user, the part of the body that is supported, that is, the right side part m1 sinks as the degassing progresses on the surface supporting the body, that is, the supporting surface, and as a result, as shown in FIG. As described above, a recess 27 having the same shape as the right side portion m1 is formed on the support surface by sinking the right side portion m1 of the body. In other words, the surfaces of the airbags 22 and 23 are deformed along the outer shape of the sunken right part m1.

The granular material 26 in the airbags 22 and 23 follows the inner peripheral surface of the bag 24 of the airbags 22 and 23 which is deformed along the right side m1 of the body as the degassing progresses. At the same time, the degree of adhesion increases.

When the deaeration is most advanced, that is, when the pressure in the air bags 22 and 23 is reduced to a substantially vacuum state, the control means 35 controls the third supply / deaeration means 33.
Then, the operation of the fourth supply and deaeration means 34 is stopped. The deaeration state can be adjusted by closing an adjustment switch (not shown) of the input means 36. Further, whether or not the vacuum state has been achieved is detected by the pressure sensor (not shown) of the deaeration system of the air bags 22 and 23, and the detection result is determined by the control means 3.
This is done by comparing with a comparison value (reference value) by 5.

Further, in synchronism with the deaeration of the right air bags 22 and 23, the control means 35 controls the first air supply / deaeration means 31 and the second air supply / deaeration means 32 to evacuate the left air bag. When the air supply to the bags 20 and 21 is started, the bags gradually inflate, and push up the left rear portion m2 of the body upward. When the air bags 20 and 21 are inflated to the maximum, the control unit 35 stops the first supply / desorption unit 31 and the second supply / desorption unit 32.

The air supply amount, that is, the swelling amount can be adjusted by operating the adjustment switch. Whether the airbags 20 and 21 are inflated to the maximum is determined by detecting the pressure of the air supply system of the airbags 20 and 21 by a pressure sensor and comparing the detection result with a comparison value by the control means 35. .

As described above, since the deaeration of the right air bags 22 and 23 and the supply of the air to the left air bags 20 and 21 are performed in synchronization with each other, the air bags 22 and 23 are supported by the right air bags 22 and 23. The right part m1 of the body is
The airbags 22 and 23 are supported by the airbags 22 and 23 with the deaeration, and are supported by the airbags 20 and 21 which gradually increase in depth with the air supply. Therefore, it is turned rightward and turned rightward.

When the adjustment switch is opened when the adjustment switch is operated to rotate to the right direction to a desired direction, the control means 35 controls the first supply / degasification means 31 or the supply / degasification means. 34 is stopped. By this stop, the air bags 20 and 21 are maintained in the inflated state, and the air bags 22 and 23 are maintained in the deaerated state.

Therefore, as shown in FIG. 4, the user M holds one side, that is, the right side m1, of the airbags 22 and 23.
It is positioned without movement in the concave portion 27 formed by the granular material 26 solidified in the body, and the left side of the body, that is, the back part m2 of the body is pushed up by the airbags 20 and 21 and supported in the state. Therefore, the user M is in a desired rightward posture, and this posture is maintained as it is.

When the body is used rightward, the right side part m1 of the body is positioned and supported by the recess 27 of the airbags 22 and 23. There is no slipping, and the body is therefore able to turn around and turn around the spine. Further, in the state in which the direction is changed, since the right side portion m1 is positioned by the concave portion 27, even if the user moves the body, the right side portion m1 does not move by sliding or the like and is maintained in a stable state. Things.

Next, when maintaining the body to the left from the state shown in FIG. 3, the above-mentioned left switch (not shown) is closed. When the leftward switch is operated, the control means 35 causes the third supply / desorption means 33 and the fourth supply / desorption means 34 to supply air to the air bags 22 and 23 disposed on the right side. The first air supply / deaeration means 31 and the second air supply / deaeration means 31 are operated so as to evacuate the air in the left air bags 20 and 21 in synchronization with the air supply operation to the air bags 22 and 23. Is operated. That is, the air in the right air bags 22 and 23 is supplied while the air in the left air bags 20 and 21 is deaerated.

That is, contrary to the rightward direction, the air in the left airbags 20 and 21 is deaerated while the right airbags 22 and 23 are supplied with air. The air bag 21 gradually contracts with degassing, the air bags 22 and 23 gradually inflate with air supply, and the body of the user gradually turns to the left.

Then, the right air bags 20 and 21
Since the weight of the user is added to the supporting surface supporting the body of the user, the left side part m3 of the supported body sinks as degassing progresses, and as a result, as shown in FIG. Conversely, a recess 28 having the same shape as the left side m3 is formed on the support surface by sinking the left side m3 of the body.

As the degassing progresses, the granular bodies 26 in the airbags 20 and 21 follow the inner peripheral surfaces of the airbags 20 and 21 deformed along the left side m3 of the body and adhere to each other. Will increase.

When the deaeration is at the most advanced state, that is, when the pressure inside the air bags 20 and 21 is reduced to a substantially vacuum state, the control means 35 performs the first supply and deaeration in the same manner as described above. The operation of the means 31 and the second supply / degassing means 32 is stopped. The deaeration state can be adjusted by closing the adjustment switch. Whether or not the vacuum state has been achieved is detected by the pressure sensor (not shown) of the deaeration system of the airbags 20 and 21 in the same manner as described above, and the detection result is compared with a comparison value by the control means 35. It is done by doing.

In synchronism with the deaeration of the left air bags 20 and 21, the control means 35 controls the third air supply / deaeration means 33 and the fourth air supply / deaeration means 34 to release the right air bag. When the air supply to the bags 22 and 23 is started, the bags gradually inflate, and push up the right rear part m4 of the body upward. When the air bags 22 and 23 are inflated to the maximum, the control means 35 stops the third supply / desorption means 33 and the fourth supply / desorption means 34.

The air supply amount, that is, the swelling amount can be adjusted by operating the adjustment switch. Whether the air bags 22 and 23 are inflated to the maximum is determined by detecting the pressure of the air supply system to the air bags 22 and 23 by a pressure sensor (not shown) and comparing the pressure with a comparison value by the control means 35.

As described above, the deaeration of the left air bags 20 and 21 and the supply of air to the right air bags 22 and 23 are performed in synchronization with each other, so that the air bags 20 and 21 are supported by the left air bags 20 and 21. M3 on the left side of the user
Is supported by airbags 20 and 21 with degassing and is supported by a concave portion 28 that gradually increases in depth with degassing, and a back surface m4 on the right side of the user is gradually expanded by airbags 22 and 23 with air supply. Since it is pushed up, it is turned leftward and turned leftward.

When the adjustment switch is opened when the adjustment switch is operated and rotated to the desired left direction, the control means 35 controls the first supply / degassing means 31 or the supply / degassing means. 34 is stopped. By this stop, the air bags 22 and 23 are maintained in the inflated state, and the air bags 20 and 21 are maintained in the deaerated state.

Therefore, as shown in FIG. 5, the user M holds one side, that is, the left side m3, of the airbags 20 and 21.
Is positioned without moving in the concave portion 28 formed by the granular material 26 that has been solidified by the above, and the back surface m4 on the right side of the user is supported by being pushed up by the airbags 22 and 23. Therefore, the user M is set to the desired leftward position, and this position is maintained as it is.

Similarly, when the user is turned to the left, the left side m3 is positioned and supported by the recessed portions 28 of the airbags 20 and 21, so that the body can face the upper surfaces of the airbags 20 and 21. There is no slipping, and the body is therefore able to turn around and turn around the spine. Further, as in the case of the rightward direction, the left side portion m3 is positioned by the concave portion 28 of the airbags 20 and 21, so that the user can maintain a stable state without slipping even if the user moves.

As described above, the body maintenance device 1 is sealed in the bag 24 made of a soft thin film member having airtightness and having a deaeration port. A bed 10 provided with an airbag composed of a large number of granular materials 26 which are brought into close contact with each other and solidified as the vehicle advances, and a mat 14 as an arrangement surface on which the airbags are arranged in two rows And air supply / degassing means 30 for degassing or supplying air from each of the airbags 20 to 23. One of the airbags is formed by a granular material which is solidified by degassing one of the airbags. To form a recess along the outer shape of the body, this recess supports one side of the body,
In addition, since the other side, that is, the back portion is supported by an air bag that is inflated by air supply, the body is directed in a predetermined direction to maintain the body position, so that the air bag on one side is evacuated. The other air bag is supplied with air to form a concave portion along the body shape while solidifying the granular material of the air bag, and the concave portion supports one side of the body and air that expands with the supply of air. The bag pushes up the other side of the body, turns the body in a desired direction, and can maintain this position in a stable state without moving.

Also, since one side of the body can rotate or change direction while being supported by a concave part along the body shape of the air bag formed with degassing, the body position changes when changing direction. This can prevent the body from slipping and moving. Further, since one side of the body is supported by the recess, the body is maintained in a stable state with a desired posture.

The airbags arranged in each of the two rows are divided into two airbags 20, 21 and 2 respectively.
2, 23, the granular body 26 is placed on the side where the weight of the bag does not depend on the weight of the user, that is, on the lower body side, in comparison with the case where one elongated airbag is arranged in each row. Since it is possible to prevent the airbag from moving, a concave portion along the outer shape can be reliably formed even in a portion where the body weight is heavy in the airbag.

In the above-described embodiment, when changing the direction of the body of the user, the deaeration of the air bags arranged in one row and the air supply of the air bags arranged in the other row are performed. The case of synchronizing is explained, but this is controlled by the control means, and the airbags in one row are evacuated to form recesses along the shape of the side of the body formed in the airbags. By supporting and inflating the other row of airbags while supporting one side,
This position may be maintained by changing the direction of the body, and when the airbags in both rows are inflated to some extent, or when they are inflated,
The airbag in one row may be deaerated only, and the airbag in the other row may be kept in the inflated state to change the body direction and maintain this posture. Also in this case, the air bag to be degassed has a concave portion corresponding to the external shape of the body, and the body does not slide and move when changing direction because the body is supported by this concave portion. Further, since the body part is supported by the recess, the body is maintained in a predetermined position in a stable state.

Further, in the above embodiment, the case where the body is oriented to one side has been described. However, this is because the body is twisted so that the muscles are extended and the upper body side and the lower body side are stretched. It is also possible to maintain this position by setting the orientations to be opposite to each other.
In this case, the air bag 21 and the air bag 22 are inflated to some extent by the control of the control means, and the air bag 20 and the air bag 23 are evacuated in this state, or the air bag 20 and the air bag 23 are
May be inflated to some extent, and in this state, the airbag 21 and the airbag 22 may be evacuated to maintain that state for a predetermined time.

It is to be noted that the twisting can be repeated if the supply and deaeration operation is accelerated.

Further, in the above-described embodiment, the case where the body is oriented to one side, that is, the case where the body is oriented in the lateral direction has been described. However, the air bags 20 and 22 are evacuated, and the air bags 21 and By supplying air to 23, the upper body may be raised at a predetermined angle to maintain this state, that is, the body position. In addition, the air bags 21 and 23 are evacuated and the air bags 20 and 22 are evacuated. By supplying air, the lower body can be pushed up and this position can be maintained. In this case, the airbag to be degassed also has a concave portion corresponding to the external shape of the body,
Since the body is supported by this recess, the body does not slide when changing direction, and since the body part is supported by this recess, the body is in a predetermined position in a stable state. Will be maintained.

In the above embodiment, two air bags are arranged in each of the two rows.
Although the description has been given of the case where the number is three, it is needless to say that the number may be three or more.

In the above embodiment, the case where the supporting device of the body position maintaining device 1 is a bed has been described.
This support device is not limited to a bed, but may be a futon or a reclining type chair.

In addition to the function of associating the change of the body direction with the change of the body direction, that is, the maintenance of the changed position, that is, the position of the body, the position maintaining device 1 may be, for example, a back or a back. When there is an affected area (for example, swollen material) that should not be pressed on the back such as the waist, the air bag is evacuated while the ball-shaped object is pressed against the area corresponding to the affected area, so that the affected area is touched. It is also possible to form a recess having a size that is not large, and to function to maintain the body position while protecting the affected part by laying the affected part in the recess and laying down the body.
