DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress structure containing a flowable substance such as water or a gel inside.

[0002]

2. Description of the Related Art Conventionally, for example, in a mattress for medical use, there is known a mattress in which a fluid substance such as water or a gel-like material is contained to enhance a body pressure dispersing effect. It is known that bedridden persons are effective in preventing bedsores.

[0003]

However, since the mattress containing the above-mentioned fluid substance is mainly made of water or a liquid having a low viscosity, the mattress tends to be heavy, so that one person needs to move or install the mattress. It is difficult to handle, especially when used by elderly people as nursing care products. Also, for example, even if you try to use it in a gudge-type bed where the waist and feet are bent to raise a part of the body, the liquid etc. in the upward rising part flows downward, so the cushioning property of the rising part In addition, there is a problem that even if the upper surface of the mattress is soiled, it cannot be easily divided and washed.

Accordingly, the present invention makes it possible to easily move and set up a mattress containing a fluid substance, and to prevent a mattress type bed from deteriorating its cushioning property even if it is partially raised. It is another object of the present invention to make it possible to easily perform washing and the like even when a part becomes dirty.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a mattress structure in which an upper surface material and a lower surface material are provided above and below a flowable substance. The liquid-tight bags are placed in a predetermined position on at least one of the upper surface material and the lower surface material.

[0006] As described above, the fluid substance is stored in a plurality of liquid-tight bags which are divided in a plane direction, and, for example, the dividing direction is set along the longitudinal direction of the mattress, so that the material can be used for a gadget bed. Even if a part is raised, extreme movement of the liquid or the like is prevented, and the cushioning property is ensured. At this time, the number of divisions of the mattress is arbitrary. However, the dividing direction is not necessarily limited to the direction along the longitudinal direction.

Here, the positioning of the liquid tight bag may be fixed to the upper surface material, to the lower surface material, or to both, but if the liquid tight bag is fixed to the lower surface material, it is disassembled. , The joining work can be performed easily. Further, a specific positioning method or the like is arbitrary, and for example, a fixing method using a fastener, a button, a locking fitting, a surface fastener, or the like can be applied.

According to the second aspect of the present invention, the upper surface member and the lower surface member can be combined and disassembled so that each liquid tight bag can be easily taken out.

With such a structure that can be disassembled and combined freely, for example, when moving and setting a mattress, it can be easily performed alone by disassembling the mattress, and there is a problem with a specific liquid tight bag. Can be easily replaced even in the case where the problem occurs. In addition, even if a part of the mattress is soiled, it can be easily washed by disassembling.

[0010]

Here, FIG. 1 is an exploded perspective view of the mattress structure according to the present invention, FIG. 2 is a cross-sectional view in a connected state, FIG. 3 is an explanatory view of an example of a mounting procedure of a waterproof liner, and FIG. 5, FIG. 5 is a plan view of a liquid-tight bag, FIG. 6 is a cross-sectional view taken along line AA of FIG. 5, FIG. 7 is an explanatory view of a method of manufacturing a reinforcing portion in the liquid-tight bag, and FIG. FIG. 9 is a diagram showing an example of various configurations of a top cover, and FIG. 10 is an explanatory diagram showing an example corresponding to a gudge.

The mattress structure according to the present invention has no problem even when used in a gudge-type bed in a water mat or the like having a high body pressure dispersion effect, and can be easily moved and installed. At the same time, even when soiled, washing and the like can be easily performed, and are suitable as, for example, household care products.

That is, the present mattress structure 1 is similar to the mattress structure shown in FIG.
And as shown in FIG. 2, the frame 2, the waterproof liner 3,
A plurality of liquid-tight bags 11 can be accommodated between a lower surface member 5 composed of the lower cover 4 and an upper surface member 9 composed of the heat-insulating cover 6, the waterproof cover 7, and the covering cover 8. And the lower surface member 5 can be combined and disassembled.

The frame 2 is formed by laminating urethane foams having different hardnesses, for example, and forming a recess in the upper urethane layer so that the bag 11 can be accommodated in the recess.

The waterproof liner 3 can be covered from the upper surface to the side surface of the frame 2 and is formed of a waterproof material such as a rubberized cloth, a resin sheet or rubber. A recess having a shape following the shape of the recess is provided. A plurality of fasteners 12a are mounted on the bottom surface of the recess at predetermined intervals in the longitudinal direction, and a plurality of locking members 13 are mounted on the inner wall surface in the width direction. A fastener 12b of the bag 11, which will be described later, is detachably connected to the fastener 12a, and a connecting member 14, which engages with a hole 11h of the bag 11, which will be described later, is freely connectable to the locking member 13. .

On the back side of the waterproof liner 3, fixed belts 15 as shown in FIG. 3 are provided at predetermined intervals in the longitudinal direction, and are connected to the frame 2 through through holes 2h of the frame 2. It can be fixed.

The lower cover 4 is formed into a box-shaped half-sack shape capable of accommodating the frame 2 by, for example, a cloth or the like, and a fastener 16a is attached along a peripheral edge on the opening side. The fastener 16a can be connected to a fastener 16b of the cover 8 described later.

The heat insulating cover 6 is sized so as to cover the upper surface of the frame 2, and is formed of a heat insulating material such as urethane foam in the embodiment.
The waterproof cover 7 includes a frame 2 covered with a waterproof liner 3, a bag 11 positioned above the frame 2,
It is formed in a box-shaped half-bag shape capable of covering the outside of the heat insulating cover 6 put thereon, and is formed of a waterproof material such as a rubberized cloth or a resin coating.

The covering cover 8 is sized to cover the upper surface of the waterproof cover 7 and has a fastener 16b on the periphery. As a configuration example of the cover 8, as shown in FIG. 9A, for example, a combination of a fiber woven into a honeycomb h structure and a polyester cotton m may be wrapped in a cloth. The honeycomb h alone may be wrapped with a fabric as shown in b), the polyester cotton m alone may be wrapped in a fabric as shown in (c), and only the fabric as shown in (d). However, when a honeycomb h or the like is used, the air permeability of the contact surface is improved in the reclined state, and the cushioning property is improved.

The liquid-tight bag 11 is formed by storing water inside a bag-shaped material such as a rubberized cloth or a resin sheet and sealing the peripheral portion thereof. A reinforcing member 17 as shown in FIG. 6 is provided. In the embodiment, the reinforcing material 17 is bent into a V-shape by bending the tape on which the PVC and the cloth are laminated as shown in FIG. 8 with the PVC side facing outward, and then, as shown in FIG. The reinforcing material 17 and the main body of the bag 11 are integrated by welding the electrode D and overlapping the periphery of the inside of the bag 11.

In the interior of the bag 11, as shown in FIG.
Can be provided, and the expansion suppressing member 18 can also be integrated by welding or the like using the same material as the reinforcing member 17. By providing such an expansion suppressing material 18, a problem that one side of the bag 11 is inflated too much or the water is unbalanced is suppressed, and the overall thickness and cushioning property can be maintained almost uniformly.

Further, the sealing portion at one end of the bag 11 includes:
As shown in FIG. 5, the fastener 12b is attached,
This fastener 12b is used as the fastener 1 of the waterproof liner 3.
2a, and a pair of holes 11h are provided in the sealing portions at both ends of the bag 11,
1h and the locking device 13 of the waterproof liner 3 are connected by a connecting device 14.

Then, this bag 11 is
Although the positioning and fixing are performed by the 2a, 12b and the connecting tool 14, as shown in FIG. 4, by making a part of the adjacent bags 11 overlap, an uncomfortable feeling such as a depression is eliminated, and Properties can be improved. Of course, the method of fixing the bag 11 and the waterproof liner 3 is arbitrary, and the fasteners 12a, 12b and
Other fixing methods may be adopted.

As shown in FIG. 2, the mattress structure 1 constructed as described above is connected to a liquid-tight bag 11 on the lower surface 5 on which the lower cover 4, the frame 2, and the waterproof liner 3 are assembled. set. That is, the hole 11h of the bag 11 and the locking device 13 of the waterproof liner 3 are connected by the connecting device 14, and the fasteners 12a and 12b are connected and fixed. At this time, as shown in FIG. 4, a part of the adjacent bags 11 is overlapped and set.

Next, after covering the heat insulating cover 6 and the waterproof cover 7 thereon, the covering cover 8 is finally covered, and the fastener 16a of the lower cover 4 and the fastener 1 of the covering cover 8 are covered.
If the connection is made at 6b, the assembly is completed.

When such a mattress structure 1 is applied to a gudge bed, for example, even if a part of the mattress structure rises up around the bent portion, only water falls in the bag 11 and the cushioning property of the rising portion is increased. There is no defect that is lost at all.

When disassembling, the bag 11 can be easily taken out by removing the fastener 16a of the lower cover 4 and the fastener 16b of the covering cover 8 in reverse order, so that, for example, the mattress structure 1 is moved. In such a case, it can be easily moved by disassembling it into a small bag 11 and carrying it. Further, even when the cover 8 and the like become dirty, washing and the like can be easily performed by disassembling.

FIG. 10A shows an example of a structure in which a portion above the bent portion of the frame 2 is reinforced by a reinforcing plate 20 such as a veneer plate to cope with a gudge. If the frame 2 is reinforced with the reinforcing plate 20 in this manner,
As shown in FIG. 10B, the raised portion can be brought into a stable state when bent, but may not always be necessary depending on the mode of the bed or the like.

The present invention is not limited to the above embodiment. Those having substantially the same configuration as those described in the claims of the present invention and exhibiting the same operation and effect belong to the technical scope of the present invention. For example, the specific configuration, material, and the like of the upper surface member 9 and the lower surface member 5 are arbitrary, and the substance contained in the liquid-tight bag 11 may be a fluid substance other than water. Further, the position for determining the position of the bag 11, the number of divisions, the direction of division, and the like are also arbitrary.

[0029]

As described above, in the mattress structure according to the present invention, the fluid substance between the upper surface material and the lower surface material is accommodated in a plurality of liquid-tight bags divided in a plane direction. Because the tight bag is positioned on at least one side of the upper surface material or the lower surface material, for example, by setting the division direction to the direction along the longitudinal direction of the mattress, it is possible to raise a part by using the gadget bed In addition, significant deterioration of cushioning property and the like are prevented. Further, if the upper surface material and the lower surface material are combined and disassembled so that each liquid tight bag can be easily taken out, for example, when the mattress is moved or installed, it can be disassembled. This is convenient because even a single person can easily perform the operation, and even if a problem occurs in the liquid tight bag, it can be easily replaced. Further, even when a part of the mattress becomes dirty, washing and the like can be easily performed.
