DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air mat device used in ordinary households and facilities.

[0002]

2. Description of the Related Art A conventional example of an air mat device will be described with reference to FIGS. As shown in FIG. 6, a plurality of airbags 2 are provided inside an external component 1 formed using urethane or a metal spring, and a controller 3 for adjusting the amount of air in the airbag 2 is externally provided. More connected. Above the airbag 2 inside the external component 1, a hose 4 having a number of air holes 5 as shown in FIG. 7 is provided as a wind discharge section, and a pump 6 is connected to one end of the hose 4. . In the air mat device having the above configuration, the controller 3 can change the capacity of the plurality of airbags 2 to adjust the pressure applied to each part of the body. In addition, by sending air from the pump 6 through the air discharge unit, moisture can be removed from the inside and a comfortable sleeping comfort can be provided.

However, in the conventional air mat device, since the airbag 2 is housed inside, the outer component 1
Therefore, it is necessary to use a high-density and hard urethane in order to form the shape, and the spring property of the external component 1 itself has to be reduced. To compensate for this, the material of the airbag 2 may be made soft, but this may affect the life. In addition, since the air blowing portion formed of the hard hose 4 as the wind discharge portion is formed by simply forming the round sending hole 5 in the blowing portion, the internal pressure of the hose 4 is increased if the blowing amount is not more than a certain level. Does not rise and therefore
It was difficult to blow out the air from all the blow holes 5 with great force. Further, although a ventilation hole (not shown) is provided in the cover 7 on the surface in the past, processing for ventilation is not usually applied to the urethane in the inside, and sufficient internal ventilation is provided. It was not done.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an air mat device which is not too hard, is excellent in sleeping comfort, and has a high dehumidifying effect by blowing air. Is what you do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described with reference to the embodiments shown in the accompanying drawings. The vertical direction and the horizontal direction used in the description are based on the direction seen from the user lying on the air mat. I do. FIG. 1 is an exploded perspective view of an example of an air mat device according to an embodiment of the present invention.
A cushion frame 10b having ventilation holes 20 formed on the side surface is placed on a flat cushion base 10a to form a cushion core 10, and a cushion pad 11 is provided from above.
To form an external component having an internal space.

In this embodiment, the above-mentioned external component is not formed of urethane which has been conventionally used, but is formed by hardening synthetic fiber cotton. The synthetic fiber cotton is characterized by having a higher elasticity than urethane and a touch similar to cotton. Furthermore, since it has the same level of strength and durability as urethane, it has sufficient performance as a constituent material.

[0010] Incidentally, the density of the synthetic fiber cotton used in this example
Range is 0.02-0.05 g / cm ^ThreeReal use
0.033 g / cm^Three, 0.040 g / cm^Three
And The hardness range is 50-200N, which is actually used
Hardness is set to 80N and 100N. However, the hardness used here
Is the force required to compress its thickness by 25%,
For example, it is necessary to make 10cm thick to 7.5cm
It is about power.

Cushion core 10 and cushion pad 1
In the internal space of the external component member surrounded by 1, three base airbags 12 are housed in a continuous state. The base airbag 12 is provided with a plurality of hooks on each side surface, and the hooks are connected to each other.

A waist-raising airbag 13 is mounted on the base airbag 12 for the purpose of pushing up the waist of the user to correct the posture. Since a plurality of fixing holes 14 are respectively formed in the belt-like horizontal mounting portion 13a and the vertical mounting portion 13b extending so as to draw a cross on the waist-raising airbag 13, the mounting methods are as follows. The remaining hooks not used for the connection of the above and the fixing holes 14 are engaged so as to be detachably attached. Since there are a plurality of fixing holes 14 to be engaged with the hooks, the mounting position can be selected according to the user's body shape.

Further, a base airbag 1 is provided as a wind discharge section for discharging air from the internal space side to remove moisture.
2, a long and narrow air bag 15 formed of a rubber film, urethane film, vinyl chloride sheet, soft hose, or the like.
Are installed. Mounting method is waist raising airbag 1
2, the fixing holes 2 provided at both ends of the airbag 15.
1 and the hook on the side surface of the base airbag 12 are engaged. The lateral mounting portions 13a provided on the waist-raising airbag 13 are formed with two through holes 22 in the vertical direction, so that the air bag 15 is passed through the through holes 22 to stabilize the mounting position. .

A plurality of slit-shaped air holes 16 having a fixed length as shown in FIG. 3 are provided in the air blowing bag 15 by forming cuts with a blade (not shown) having a fixed width. ing. Since the blow hole 16 has a feature that it does not open unless the pressure is equal to or higher than a certain pressure, the blow bag 15 is in a contracted state as shown in FIG. At the same time, the ventilation hole 16 is closed. Even if the air bladder 15 is inflated by the air blown from the pump 6, if the internal pressure has not reached a certain pressure, the air blowing hole 16 does not open as shown in FIG. 4B. Further, the air is continuously blown, and when the internal pressure reaches a certain pressure or more, the air blow hole 16 is opened as shown in FIG. 4C, and the air is expelled from the inner side of the air mat in a vigorous manner. Dehumidification becomes possible. Also, as shown in FIG. 5 (a), even when the air blowing bag 15 is twisted when the air blowing is stopped, as shown in FIG. It also has the feature of being eliminated.

Further, when actually used, the entire external components are covered with a mat cover 17, but the side surfaces of the mat cover 17 communicate with ventilation holes 20 formed in the cushion frame 10b. A ventilation hole 18 is formed at the position. Thereby, when the user performs weight transfer by turning over or the like, the internal space is naturally ventilated through the ventilation holes 20 as shown in FIG. 2, and moisture accumulated in the internal space is efficiently discharged. Can be.

[0016]

As described above, according to the first aspect of the present invention, it has sufficient strength and durability, has elasticity like a spring, and has good touch close to cotton. By forming the external component using chemical fiber cotton, there is an effect that a good sleeping comfort can be provided to the user.

According to the second aspect of the present invention, since ventilation is automatically performed by shifting the weight of the user, there is an effect that moisture is prevented from accumulating in the internal space.

Further, according to the third aspect of the present invention, the air blower, which is in a contracted state when no air is blown, gradually expands due to the air blow, and the air blow hole does not open unless the internal pressure becomes higher than a predetermined pressure. With this valve structure, there is an effect that a high internal pressure is applied to the blowing section even with a small amount of air, and when the blowing hole is opened, the air can be released vigorously to efficiently remove moisture.
