Abstract

PURPOSE: To keep air going through a mattress without reducing the performance of the spring of the mattress by using a covering which covers a spring unit, air bags, and a case to store the air bags and which can be opened/closed. CONSTITUTION: This mattress device M has a spring unit 1 formed in a prescribed rectangular plate. The bottom of a case 8 is bonded and layered on a protection sheet 6 on top of the spring unit 1, and therefore, the case 8 is kept from slipping on the spring unit 1. The case 8 consists of a bottom board 8a and a frame 8b which is mounted integrally around the upper surface of the bottom board 8a to be a storage room 9. Air bags are stored in rows in the longitudinal direction of the mattress device M inside the storage room 9. An air bag is formed as a bag by attaching the upper sheet to the lower sheet along the circumference. The upper and the lower sheets are attached at several points so that dents 11 and projections 12 are formed on the rear of the surface when the bags are filled with air, and a through hole 13 is bored in an attaching point in a dent 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double cushion type mattress device utilizing the cushioning performance of a spring and an air bag.

[0002]

2. Description of the Related Art Conventionally, a mattress device is constructed by polymerizing a protective material such as sisal pad and a synthetic resin mesh on the upper surface of a spring unit and an elastic body such as urethane foam on the protective material, and then polymerizing this polymer as an exterior body. It is covered with. In such a mattress device, an air bag is interposed between the elastic body and the exterior body in order to change the elasticity and hardness given to the user or to prevent the occurrence of bedsores. The hardness can be changed by adjusting the pressure of the air supplied to the air bag.

By the way, an air bag is made of a sheet of non-breathable vinyl or rubberized cloth.
As a result, the air permeability in the vertical direction is lost, so that irregularities are set to be formed during expansion. However, the unevenness is crushed by the weight of the user and the breathability cannot be maintained,
Further, the periphery of the air bag may be crushed to impair the overall shape of the mattress.

The inability to maintain breathability impairs cushioning performance of the air bag and spring, and also loses the function for preventing floor sores.

[0005]

SUMMARY OF THE INVENTION Therefore, it is possible for the user to maintain the spring performance of the air bag that can maintain the breathability and change the hardness and that does not impair the appearance of the overall shape. A mattress device that can provide sleeping comfort due to its hardness has been desired.

The present invention has been made in view of the above circumstances. An object of the present invention is to maintain air permeability without impairing the cushioning performance of the spring and to maintain the overall shape of the air. It is an object of the present invention to provide a mattress device that accommodates a bag, and also to provide a mattress device that can constantly supplement the leakage of air from the air bag over time due to the user's use.

[0007]

In order to solve the above problems, the invention set forth in claim 1 is directed to a spring unit, a case having an accommodating portion provided on the spring unit, the upper surface of which is open; It is composed of a plurality of air bags housed in the housing portion, the spring unit, the air bag, and an openable / closable exterior body covering the case. The case is a bottom plate made of a foamed synthetic resin elastic body and stands around the bottom plate. The airbag is formed of a frame body, and the airbag is formed into a bag shape by joining the peripheral edges of the upper sheet and the lower sheet, and when inflated, a plurality of uneven portions are formed on the surface, A through hole is formed at a joint portion between the upper sheet and the lower sheet.

Further, the invention according to claim 2 is such that a spring unit, a case having a housing portion provided on the spring unit and having an open upper surface, and an internal air housed in the housing portion of the case. Equipped with a plurality of airbags with different pressures and a pressure adjusting device to set the supply air pressure to the airbags and maintain the set pressure,
It is composed of the spring unit, an air bag, and an openable / closable exterior body covering the case, and the case is formed of a bottom plate made of a foam synthetic resin elastic body and a frame body standing around the bottom plate. The back is formed in a bag shape by joining the peripheral edges of the upper sheet and the lower sheet, and forms a plurality of uneven portions on the surface when inflated, and at the joint portion of the upper sheet and the lower sheet in the concave portion. Is characterized by having a through hole.

[0009]

According to the invention of claim 1, since the air bag is housed in the case formed by the bottom portion made of the foam synthetic resin elastic body and the wall portion provided upright around the bottom portion, the weight of the user is reduced. As a result, even if the air bag tends to sink, the case frame tries to prevent this, and the air permeability can be maintained in the case housing portion.

According to the second aspect of the present invention, since the plurality of airbags having different internal air pressures housed in the housing portion of the case are provided, each of the user's back, buttocks, and feet is provided. Since it is possible to adjust to the difference in weight, it is possible to adjust the comfort of the user and set the supply air pressure to each part beforehand.
The air can be automatically pumped to maintain the set pressure when the user leaks air over time.
