Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air mattress device for elastically holding a user by air pressure.

[0002]

2. Description of the Related Art For example, when it is difficult for a user to freely move his / her body by himself / herself, a wake-up type bed apparatus that can raise the user's upper body is used. 2. Description of the Related Art In a rising bed device, a mattress device placed on the floor plate is required to be configured to be bendable according to the ups and downs of a part of the floor plate.

In order to make the mattress device bendable, for example, in the case of a mattress device using a spring unit for a cushion body, the spring unit may be configured to be bendable. The resistance at the time of bending is large, and it may be difficult to bend smoothly.

[0004] As a mattress device which is relatively easy to bend, a cushion body using an elastic material such as foamed polyurethane is used. In the case of a cushion body made of an elastic material, it is inevitable that performance degradation due to sagging will occur due to long-term use, and since the hardness is constant, it is set to the hardness desired by the user. Sometimes you can't.

[0005] Furthermore, a cushion body made of an elastic material is compressed by a load, so that a repulsive force corresponding to the load is generated. For this reason, for example, a heavy part of the human body such as a user's buttocks receives a large repulsive force, so that the part may be squeezed to deteriorate the sleeping comfort or to easily get out of bed.

Therefore, an air mattress device is sometimes used instead of the cushion body made of an elastic material. According to the air mattress device, the hardness can be changed by adjusting the pressure of the compressed air supplied to the air mattress device. Because it is easy to use, it can be used for a wake-up type bed device.

The air mattress device has an air bag, as is well known, and an air pump is connected to the air bag via a supply pipe. And
By supplying compressed air from the air pump to the air bag, the user can be elastically supported by the air pressure.

[0008] The airbag is required to adjust the pressure, that is, the hardness, according to the weight and preference of the user. In order to supply air to the air bag, an electric or manual air supply pump is provided, a pressure regulator for adjusting the pressure of the air bag, a supply / exhaust valve that sequentially supplies air to each air bag, and a supply / exhaust switching. Control devices such as mechanisms are required.

Conventionally, the above-described air supply pump and other devices are arranged separately from the mattress, and are connected to the mattress by an air hose. For this reason,
In some cases, the air supply pump and other devices or an air tube connecting the air supply pump and the air bag hinder bed making and walking. Furthermore, the air mattress device has poor air permeability in the thickness direction, so that the user's body is easily stuffy, which may cause bedsores.

[0010]

As described above, in the conventional air mattress device, the air supply pump and other devices are separate from the mattress, and are connected to the mattress by an air hose. Was. for that reason,

FIG. 3 shows a bed apparatus 1, which is provided with a rectangular frame-shaped bed frame 2. At the four corners of the bed frame 2, legs 4 having casters 3 with stoppers provided at the lower ends are vertically provided so that the bed frame 2 can be moved.

A head board 5 is provided upright at one longitudinal end of the bed frame 2, and a foot board 6 is provided upright at the other end. Further, a floor plate 7 is disposed on the bed frame 2. This floor plate 7 is divided into a plurality of floors. In this embodiment, the floor is divided into first to fourth floors 7a to 7d.

The second second floor 7b from the side of the headboard 6 is fixed to the bed frame 2, and the second floor 7b
The first floor 7a is rotatably connected to one side of the floor 7b, and the third floor 7c and the fourth floor 7d are connected to the other side.
And are sequentially connected rotatably.

A drive mechanism 8 for raising the back is provided on the lower surface side of the bed frame 2. The drive mechanism 8 has a case 9, and a drive source 11 is provided on one side of the case 9.

The first arm 1 is provided at one end of the case 9.
2 is provided rotatably, and a second arm 13 is provided on the other end side.
Are provided rotatably. These arms 12, 1
Numeral 3 is driven to rotate by the driving source.

At the end of the first arm 12, a first roller 14 is rotatably provided. The first roller 14 is in contact with a rail member 15 provided on the lower surface of the first floor 7a. Therefore, when the first arm 12 is rotationally driven in the direction of the arrow, the first floor 7a is driven in the rising direction.

At the end of the second arm 13, a second roller 16 is rotatably provided. The second roller 16 is in contact with an inclined plate 17 provided at the lower end of the third floor 7c. Therefore, when the drive source 11 is operated and the second arm 1 is rotationally driven in the direction indicated by the arrow, the third floor 7c is driven in the rising direction.

The fourth floor 7d is linked with the rotation of the third floor 7c. A link 18 is provided between the end of the fourth floor 7d and the bed frame 2 so that both ends are rotatably connected. Therefore, the third
The fourth floor 7d interlocked with the floor 7c is held substantially horizontally.

An air mattress device 21 is placed on the floor plate 7d. This air mattress device 21
As shown in FIGS. 1 and 2, a rectangular plate-shaped holding member 2 formed of an elastic material, which constitutes a mattress body 20.
2 The holding member 22 is formed of a material having air permeability (continuous foaming) such as urethane home, foamed polyethylene or foamed rubber.

At the periphery of the holding member 22, a reinforcing member 24 formed of an elastic material that is harder than the holding member 22 and that can bend together with the holding member 22 is formed at the lower end in the height direction on the side surface thereof. Only the holding member 2
2 and has a predetermined gap S (passage) between a portion other than the lower end portion and the holding member 22.
In addition, supply pipes 27 and 28 for supplying compressed air to an air tube 26 serving as an air bag to be described later are passed through the gap S.

Since only the lower end of the reinforcing member 24 in the height direction is bonded and fixed to the holding member 22, the bending of the holding member 22 prevents the reinforcing member 24 from having a large resistance to bending. You. Moreover, the holding member 2
When the holding member 22 is bent by passing the supply pipes 27 and 28 through the gap S between the reinforcing member 24 and the supply pipe 2,
There is no possibility that 7, 28 is bent too much and collapsed.

The reinforcing member 24 is made of an elastic material having air permeability, like the holding member 22.
The holding member 22 and the reinforcing member 24 constitute the mattress body 20.

The mattress body 20 has a prism-shaped soft member 24A made of an elastic material softer than the reinforcing member 24 joined and fixed to the outer surface of the reinforcing member 24 located at one end in the longitudinal direction. ing.

The holding member 22 and the reinforcing member 24, that is, the mattress main body 20 are covered with an outer covering 23. The exterior fabric 23 is formed by sewing a breathable fabric into a bag shape, and the mattress body 20 is accommodated therein.

The exterior base 23 may be in the form of a sheet, not a bag, and the periphery may be folded into the lower surface of the mattress body 20 to cover the upper surface and the outer peripheral surface of the mattress body 20. As the fabric used for the exterior fabric 23, a fabric that has air permeability but does not allow liquid to pass through may be used. By using such fabric, moisture from the body of the user causes the exterior fabric 23 to pass through. Passing and holding member 2
2 and the reinforcement member 24 can be prevented from being trapped.

The holding member 22 is provided with a plurality of holding grooves 25 as holding portions along the width direction at predetermined intervals in the longitudinal direction. The holding groove 25 has a circular cross section as shown in FIG. 4, and has an opening 25a opened at a predetermined width on the upper surface of the holding member 22. The width of the opening 25a is the same as that of the holding groove 25.
It is set to about half of the diameter dimension. Thereby,
The air tube 26 is not easily removed from the holding groove 25, and the width W between the adjacent openings 25a shown in FIG. 4 can be increased. In this embodiment, the width dimension W is
Are set to be substantially the same as the external dimensions of the above, thereby increasing the area in which the user's body can be supported by the air-permeable holding member 22.

The air tube 26 having substantially the same external dimensions and length as the holding groove 25 is removably mounted in the holding groove 25 by elastically deforming both sides of the opening 25a of the holding member 22. Have been. The air tube 26 is formed in a cylindrical tube shape using a non-breathable sheet material, for example, a rubberized cloth, and a part of the outer peripheral surface is exposed to the opening 25a.

The plurality of air tubes 26 mounted in each holding groove 25 are divided into a plurality of groups as shown in FIG. In this embodiment, in the longitudinal direction of the holding member 22, the adjacent air tubes 26
Group G1 and a second group G2.

The air tubes 26 of the first group G1
Are connected to branch pipes 27a branched from the first supply pipe 27, respectively, and the air tubes 26 of the second group G2 are connected to the branch pipes 28a branched from the second supply pipe 28.
Are connected respectively. First and second supply pipes 27,
Numerals 28 are connected to an air supply pump 35 which is a compressed air supply source via a switching air supply / exhaust mechanism 45. The air supply pump 35 is of a flow rate adjusting type having a dial type flow rate adjusting section 35a, and the start and stop of the air supply pump 35 and the above-mentioned switching feed / exhaust mechanism 45 are controlled by a control device 38 such as a hand switch. It has become.

The switching air supply / exhaust mechanism 45 supplies compressed air from the air supply pump 35 to the air tubes 26 of the first group G1 and the air tubes 26 of the second group G2 for a predetermined time according to a control signal from the control device 38. As it can be sent alternately later,
A first diffuser tube 48 is provided for evacuating the compressed air of the group not supplied with the air little by little. This radiation tube 4
Numeral 8 is a thin tube sufficiently smaller than the supply pipes 27 and 28, and the displacement can be controlled by the inner diameter and length thereof.

The air tube 2 between the first group G1 and the second group G2 is switched by the switching air supply / discharge mechanism 45.
6 and alternately send compressed air, and the compressed air of the group not sending air can be exhausted. Thereby, since the location supported by the air tube 26 of the user's body lying on the mattress body 20 changes with time, the occurrence of floor rubbing can be reduced as compared to the case where the same location is continuously supported. .

The first supply pipe 27 and the second supply pipe 28
T-shaped joint 39 in the middle of
Each of the supply pipes 27 and 28 is connected to two of the two connection portions and interposed therebetween. The remaining connections of this joint 39
One end of a second diffusion tube 41, which is sufficiently small in diameter as compared with the supply tubes 27 and 28 and has a predetermined length, is connected. The diffuser tube 41 is formed in a tube shape from a synthetic resin such as silicon, and is set to a predetermined flow resistance by its inner diameter and length.

The first radiation pipe 48 and the second radiation pipe 41
As shown in FIG. 1, the other end is guided to the center in the longitudinal direction on the upper surface side of the mattress body 20 and both ends. As a result, a part of the compressed air supplied from the pump 35 to each of the supply pipes 27 and 28 is diffused to the upper surface of the mattress body 20 on the inner surface side of the exterior ground 23 through the radiation pipes 41 and 48. The drying action of the dissipated air prevents any build-up of moisture on the mattress device. Moisture, combined with poor blood circulation, causes the body to be overly moist and causes bedsores, so the air radiated from the diffusion tube 41 dries the skin and contributes to prevention of bedsores.

Each group G is controlled by controlling the amount of compressed air supplied from the pump 35 to the air tube 26 and the amount discharged to the atmosphere from the diffusion tubes 41 and 48.
The hardness of the air tubes 26 of 1 and G2 can be controlled. In other words, a mattress device having a hardness according to the user's preference can be provided.

The soft member 24A provided at one end in the longitudinal direction of the mattress body 20 has a first storage portion 46 and a second storage portion 47 which are open to the respective side surfaces at one end and the other end in the longitudinal direction. Are formed. The first storage section 46 stores the air supply pump 35, and the second storage section 47 stores the switching feed / exhaust mechanism 45.

The inner surface of the first accommodating portion 46 is an uneven surface having a plurality of convex portions 49 having a triangular cross section formed at predetermined intervals, and the upper and lower surfaces of the air supply pump 35 are formed by the convex portions 49. It is elastically supported. Since the air supply pump 35 is partially supported by the convex portion 49, the convex portion 49 is easily elastically deformed by vibration generated during operation. Therefore, the protrusion 49 absorbs the vibration of the air supply pump 35, so that the vibration can be prevented from being transmitted to the mattress body 20.

A holding band 50 is provided around the portion of the mattress body 20 where the first storage section 46 is formed. Both ends of the holding band 50 are detachable by a velvet fastener (not shown), and the both ends are engaged in a state where the opening surface of the first storage portion 46 is closed. The stored air supply pump 35 can be prevented from falling off.

The switching feed / discharge mechanism 45 is provided in the second storage section 4.
7 is elastically deformed and stored. As a result, the switching feeding / discharging mechanism 45 is prevented from dropping out of the second storage part 46. However, like the first storage part 46, the switching feeding / discharging mechanism 45 is dropped by providing the holding band 50. May be prevented.

The air supply pump 35 housed in the first housing 46 sucks outside air through the portion of the exterior ground 23 that covers the first housing 46. Therefore, a part of the exterior ground 23 acts as a filter for the air supply pump 35, so that a filter (not shown) provided on the air supply pump 35 is prevented from being soiled at an early stage. That is,
The filter replacement cycle of the air supply pump 35 can be lengthened.

As shown in FIG. 6B, a fastener 51 is provided on the exterior ground 23 at a portion corresponding to one longitudinal end of the mattress body 20, that is, a portion corresponding to the soft member 24A. . Therefore, when the fastener 51 is opened, the first and second storage portions 46 and 47 can be opened.

According to the air mattress device 21 having the above structure, the holding groove 25 is formed in the holding member 22 made of an elastic material having air permeability, and the air tube 26 is elastically detachably held in the holding groove 25. The air mattress device 21 has flexibility as a whole.

Therefore, the air mattress device 21
Is placed on the floor plate 7 of the bed device 1 of the wake-up type, and when the first floor portion 7a of the floor plate 7 is raised, the raising operation can be easily performed, and the first operation can be easily performed. The air mattress device 21 can be reliably bent according to the rising of the floor 7a.

Although the air mattress device 21 has flexibility, a reinforcing member 24 made of an elastic material harder than the holding member 22 is provided around the holding member 22. For this reason, the air mattress device 21 not only maintains its external appearance shape by the reinforcing member 24, but also has a problem that the peripheral portion is hard and thus hard to set.

Each of the air tubes 26 of the air mattress device 21 is provided along the width direction of the holding member 22. That is, the air tube 26 is provided along a direction intersecting the undulating direction of the floor 7a.

Therefore, even if the holding member 22 is bent by raising the floor 7a, the air tube 26 is not bent.
Not only can the raising operation of a be easily performed, but also the air tube 26 can be prevented from being damaged early because the air tube 26 is not repeatedly bent.

The air tube 26 is elastically detachably held by the holding portion 25 of the holding member 22. Therefore, the air tube 26 can be easily removed from the holding member 22, so that maintenance and inspection, replacement work, and the like can be performed easily and quickly.

An opening 26 is formed in the holding groove 25 holding the air tube 26, and a part of the air tube 26 is exposed from the opening 26. Since the air tube 26 has a body pressure dispersing effect of dispersing the load when the air tube 26 receives the load of the user, a large repulsive force is not generated in a heavy portion of the user's body.

As a result, a heavy part of the user, for example, the buttocks, is prevented from being strongly pressed, so that not only the sleeping comfort is improved but also the bedsore is less likely to occur even if the user is lying on the back for a long time. .

The air tube 26 is held in the holding groove 25 of the holding member 22 made of an elastic material having air permeability. Therefore, even if the air tube 26 does not have air permeability, the air permeability of the holding member 22 can prevent moisture from being trapped between the user's body and the upper surface of the air mattress device 21. Also hardly occurs.

That is, the mattress device 21 is formed by combining the holding member 22 made of an elastic material having air permeability and the air tube 26, thereby having air permeability, a body pressure dispersing effect, and a wake-up type bed. When used for the device 1, it can be easily and reliably bent according to the rising of the floor 7a.

On the other hand, the first supply pipe 27 and the first supply pipe 28 for supplying the compressed air from the pump 35 to the air tubes 26 of the first group G1 and the second group G2 A second diffuser tube 41 for dissipating a part of the compressed air from 35 to the atmosphere is provided.

Therefore, compressed air is supplied from the pump 35 to each of the air tubes 26,
When the pressure exceeds a predetermined value, a part of the compressed air
Of the air tube 26, that is, the hardness of the air tube 26 is maintained in a predetermined state.

The flow resistance of the second diffusion tube 41 can be set by its diameter and length. Therefore, by setting the flow path resistance according to the diameter and length of the second diffusion tube 41, the hardness of the air tube 26 can be set according to the user's preference and weight. For example, the second
If the diffusion tube 41 is shortened, the flow path resistance is reduced, so that the hardness of the air tube 26 can be softened. Also, the flow path resistance can be reduced by increasing the inner diameter to make the air tube 26 softer. can do. When the air tube 26 is hardened, the second diffusion tube 41 may be lengthened or thinned.

When a sudden impact is applied to the air tube 26, the compressed air in the air tube 26
The gas is radiated to the atmosphere from the diverging tube 41 connected to the radiating tubes 7 and 28. Therefore, it is possible to prevent the pressure in the air tube 26 from being excessively increased and damaged.

Since the pump 35 has the flow rate adjusting section 35a, the pump 35 is controlled by the flow rate adjusting section 35a.
It is possible to adjust the flow rate of the compressed air discharged from the hopper. Accordingly, by setting the amount of air supplied to the air tube 26 in accordance with the amount of air radiated from the diffusion tube 41, the amount of compressed air in the air tube 26 can be made substantially constant. It can be maintained at an appropriate hardness.

The compressed air radiated from the first diverging tube 48 and the second diverging tube 41 is discharged to the upper surface of the mattress body 20. Therefore, it is possible to prevent moisture from remaining on the upper surface of the mattress device due to the dissipated air, thereby preventing the user from rubbing the floor due to the moisture.

The air supply pump 35 is housed in a first housing section 46 formed in the soft member 24A, the switching feed / exhaust mechanism 45 is housed in a second housing section 47, and the first and second supply pipes are provided. By passing 27 and 28 through the gap S between the holding member 22 and the reinforcing member 24, the mattress main body 20 and each device constituting the air supply means are integrated.

Therefore, not only does the air supply pump 35 and the switching air supply / exhaust mechanism 45 obstruct,
It is not necessary to secure a dedicated installation place for the above-mentioned devices, and further, since the first and second supply pipes 27 and 28 are passed through the gap S, they are not inadvertently crushed. The supply and discharge of the compressed air to and from the air tube 6 can be performed smoothly.

A projection 49 is formed on the inner surface of the first storage section 46, and the air supply pump 35 stored in the first storage section 46 is supported by the projection 49. The vibration generated by the operation of
The convex 49 is absorbed by being elastically deformed. For this reason, the vibration of the air supply pump 35 is less likely to propagate to the surroundings, so that the vibration is not transmitted to the user who is lying on the mattress apparatus and gives a feeling of discomfort.

Further, since the soft member 24A in which the first storage portion 46 is formed is made of a soft elastic material, the vibration of the air supply pump 35 is hardly propagated, and the sleeping comfort is lowered. Is prevented.

The air supply pump 35 housed in the first housing 46 is held by a holding band 50. Therefore, even if the mattress device is carried or folded, the air supply pump 35 does not fall out of the first storage section 46.

The present invention is not limited to the above embodiment, but can be variously modified. For example, the case where a tubular air tube is used as the air bag has been described, but the shape of the air bag is not limited to a tube, and may be a rectangular plate shape having a predetermined dimension with respect to the longitudinal direction of the holding member. Good. Further, in the above-described embodiment, the air tubes are divided into two groups, and the two supply pipes for supplying the compressed air to the respective groups are provided with the second diffuser pipes. If not divided, only one second emission tube may be used, and even if divided into multiple groups,
The supply pipes corresponding to the respective groups may not be provided with the second diffusion pipe, and only one second diffusion pipe may be provided on the projecting side of the pump. Further, a second diffusion tube may be provided for each air tube.

Further, by providing the first discharge pipe having a smaller diameter than the supply pipe in the switching feed / exhaust mechanism, the pressure of the air bag can be adjusted in combination with the first discharge pipe provided in the supply pipe. It can be performed with higher accuracy.

In the above embodiment, the air tube is provided on the holding member having the holding groove, and the reinforcing member is bonded and fixed to the holding member. However, the air tube may be configured as shown in FIG. That is, the holding member 22 does not have the holding groove 25 by omitting the reinforcing member 24 and has the concave portion 22 opened to the upper surface side.
a, and a plurality of, in this case, three, airbags 26A formed in a flat bag shape in the concave portion 22a are housed side by side.

The holding member 22 is formed with first and second storage portions 46A and 47A, in which the air supply pump 35 and the switching feed / exhaust mechanism 45 are stored, respectively.
The supply pipes 27 and 28 connecting the air bag 26A to the air supply pump 35 and the switching air supply / exhaust mechanism 45 pass through the gap S between the air bag 26A and the inner surface of the concave portion 22a. , 28 are connected to the open ends of each air bag 26.
A is drawn out to the upper surface side of A.

Even with such a configuration, the same operation and effect as those of the above-described embodiment can be obtained. In addition, a storage section is formed in the mattress main body, and an air supply pump, a switching air supply / exhaust mechanism, and the like are stored therein, but when the mattress main body is foamed, the above-described devices are stored in advance in the inside. You may.

Can be favorably absorbed.

According to the seventh aspect of the present invention, since the air pump is housed in the housing formed by opening on one side of the mattress main body, the hardness of the air supply pump is directly transmitted to the user by the mattress main body. In addition, heat generated from the air supply pump is released to the outside from the opening surface of the storage portion and is not transmitted to the user, so that the sleeping comfort is not reduced.

Further, since the air supply pump housed in the housing part uses the exterior ground as a filter to suck the outside air, it is possible to prevent the filter of the air supply pump from being soiled at an early stage.
