BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water mattress device particularly suitable for a wake-up bed.

[0002]

2. Description of the Related Art There are various types of mattress devices, and a water mattress device is known as one of them. In the water mattress device, the liquid contained in the water bag flows in accordance with the uneven shape of the body of the user who is lying on the upper surface, and accordingly, according to the amount of compression, like a mattress device including a spring unit. Since no reaction force is generated, a heavy part of the user's body, for example, the buttocks is not strongly pressed.

[0003] If the user is not partially pressed against the body, the mattress device can be used, for example, for a bed for a sick or elderly man who has to lie down for a long time to prevent so-called bedsores. There are things you can do. Therefore, recently, attention has been paid to such advantages, and water mattress apparatuses have been widely used.

[0004] In the case of beds for the sick and elderly, a so-called wake-up bed is used in which a part of the floorboard can be raised and lowered for a user who cannot get up on his / her own bed. . When a water mattress device is used in such a wake-up type bed, the water mattress device is bent in accordance with the undulation of the floorboard.

When the water mattress device is used in a substantially horizontal state, the liquid stored in the water bag only flows according to the uneven shape of the user's body, but as described above. When the floorboard is bent in accordance with the undulations, it may flow due to the bending.

[0006] Since the water bag is usually formed of a flexible waterproof sheet made of rubber or the like, the liquid in the water bag is also easy to flow. Therefore, when the water mattress device is used in a wake-up bed, the liquid in the water bag in the portion bent upward according to the rise of the floor plate flows downward, and there is almost no liquid in that portion. It will be in a state,
Performance could not be maintained, making it difficult to use.

[0007]

As described above, in the conventional water mattress device, the liquid in the water bag easily flows. In some cases, the liquid (thickness) of each part is not constant unless it is installed almost horizontally, which makes it difficult to use.

[0008] This invention was made based on the above circumstances, and the purpose is that even if the bed is bent or installed in an inclined state, the liquid in the upper part is lowered. It is an object of the present invention to provide a water mattress device capable of preventing the water from flowing into the water mattress.

An embodiment of the present invention will be described below with reference to the drawings. The water mattress device M shown in FIG. 1 includes a lower elastic member 1 formed in a rectangular plate shape. The lower elastic member 1 has a structure having air permeability and elasticity by, for example, entangling polyester fibers in a laminated state and bonding the fibers to each other with a rubber-based adhesive. The lower elastic member 1 is covered with a nonwoven fabric 2 and has slits 1a along the width direction formed at predetermined intervals in the longitudinal direction on the lower surface side so as to be easily bent.

The polyester fiber of the lower elastic member 1 is
Since it has the same function as the spring wire, the hardness of the lower elastic member 1 can be set by changing the thickness thereof. it can.

On the upper surface of the lower elastic member 1, a plurality of tube-shaped water bags 4 held by a holder 3 are provided.
Are arranged side by side along the longitudinal direction of the lower elastic member 1. The water bag 4 is formed of a waterproof sheet such as rubber, and contains therein a liquid L such as water or gel.

The holding body 3 includes a cloth base sheet 5 formed in a rectangular shape having substantially the same size as the lower elastic member 1;
The base sheet 5 is bent into a wave shape along its longitudinal direction and sewn, so that a plurality of cylindrical members along the width direction are formed between the base sheet 5 and the upper surface of the base sheet 5. The accommodation section 6 is formed of a holding sheet 7 also made of cloth, which is continuously provided along the longitudinal direction. The water bags 4 are inserted and held in the respective housing portions 6.

A peripheral portion of the upper surface of the base sheet 5 is exposed from the pressing sheet 7, and a frame 8 is provided on the lower portion by bonding and fixing the lower surface thereof. The frame body 8 is formed of an elastic material such as urethane foam to prevent the water bag 4 housed and held in the housing part 6 from shifting and moving, and to surround the water mattress device M. It has the function of maintaining the shape and elasticity of

The laminate of the lower elastic member 1 and the water bag 4 is covered with an exterior body 11. As shown in FIG. 2, the exterior body 11 has a lower mirror ground 12 covering the lower surface of the lower elastic member 1. The lower edge of the base 13 covering the outer peripheral surface of the frame 8 and the peripheral edge of the base sheet 5 are provided on the peripheral edge of the lower mirror ground 12 as a first tape edge 14.
Has been sewn by. As a result, the lower mirror 1
The base 2 and the base sheet 5 form a bag portion 1b into which the lower elastic member 1 is inserted.

The lower end of the connecting cloth 17 is sewn to the upper end of the gusset 13 by a second tape edge 15, and the upper mirror 1 which covers the upper surface of the water bag 4 is attached to the upper end.
8 is sewn by a third tape edge 19.

An intermediate portion of the connecting cloth 17 can be disassembled by a fastener 16. That is, the upper mirror base 18 is detachable by the fastener 16. Therefore, by removing the upper mirror base 18, the water bag 4 is removed.
Maintenance inspection can be easily performed.

The water mattress device M is used for a wake-up bed 21 as shown in FIG. 4, for example. This wake-up bed 21 has a bed frame 22. In the frame of the bed frame 22, a first floor plate 23 and a second floor plate 24 divided at an intermediate portion in the longitudinal direction are rotatably provided by a hinge mechanism (not shown). A receiving bar 25 for engaging and supporting each floor plate that has been laid down horizontally is provided on the inner peripheral surface of.

A drive mechanism 2 is provided in the bed frame 22.
6 are provided. The drive mechanism 26 has a first arm 27 and a second arm 28 that are driven to rotate. The tip of the first arm 27 is pivotally connected to the lower surface of the first floor plate 23, and the tip of the second arm 28 is the second arm 28.
Is pivotally attached to the lower surface of the floor plate 24.

As a result, when the arms 27 and 28 are driven, the first floor plate 23 and the second floor plate 24 can be rotated in the ascending direction as shown in FIG. ing. Then, the first floor panel 23 and the second floor panel 2
The water mattress device having the above configuration is mounted on the upper surface of the water mattress 4.

According to the water mattress device M having such a configuration, the liquid is divided and stored in the plurality of tube-shaped water bags 4, so that the liquid is stored in each of the water bags 4.
Will flow only within the range. Therefore, as shown in FIG.
Even if it is bent in accordance with the rotation of 4, the liquid does not accumulate in the lowered portion of the water mattress device M, so that its performance is not impaired.

Moreover, the size of each of the water bags 4 with respect to the inclination direction of the floor boards 23 and 24 is reduced by arranging the longitudinal direction along the width direction of the water mattress device M. Therefore, also by this, when the floor plates 23 and 24 are raised, the liquid in each water bag 4 can flow very little downward in the inclined direction.

On the other hand, since the water bag 4 is formed of a flexible waterproof sheet, the water bag 4 is deformed flat and adheres to the lower elastic member 1, and moisture adheres to the adhered surface to generate mold. And the proliferation of bacteria.

However, since the lower elastic member 1 has air permeability, it prevents moisture from being trapped between the lower elastic member 1 and the contact surface of the water bag 4. To prevent growth.

Further, since the liquid L contained in the water bag 4 is incompressible and has little cushioning property, the lower elastic material 1 on which the water bag 4 is placed is not used.
Has cushioning properties. Therefore, the water mattress device M is provided with cushioning properties as a whole, so that a good feeling can be given to the user.
