[Conventional technology]

Generally, mattress devices are made by connecting a large number of coil springs in a matrix. The elastic material is polymerized on the upper and lower surfaces of this spring unit. These are covered with an exterior body.

0003 Therefore, the cushioning properties of a mattress device with such a configuration are limited to the top side or is the same no matter which side of the bottom side is used. That is, one mattress device is Cushions have a certain level of firmness, so they are comfortable depending on the user. For example, when the cushioning properties are different or when you want to change the cushioning properties depending on the physical condition of the user, etc. It was very inconvenient.

0004 Therefore, the present applicant proposed the mattress device disclosed in Japanese Patent Publication No. 1-61047. proposed. The mattress device shown in this publication has a first cushion body. The spring unit and the second spring unit are polymerized, and this polymer is Elastic bodies are attached to the upper and lower surfaces, respectively, and these are covered with an exterior material. Above number The first spring unit and the second spring unit have elastic changes under the same load. They are formed with different shapes and sizes.

[0005] Therefore, the user should use it with the first spring unit side facing up, or Depending on whether you use the mattress with the second spring unit side up, Different hardnesses are available.

[0006] Conventionally, mattress devices with two hardness levels have been A first spring unit, each consisting of a spring made of a bent wire rod, serves as a spring body. A knit and a second spring unit were used.

[0007] Therefore, the bush between the first spring unit and the second spring unit In order to change the elasticity (hardness), it is necessary to change the wire diameter and The material must be changed.

[0008] However, by changing the characteristics of the wire material, it is possible to make each spring unit have different hardness. When using springs, the usable wire diameter is limited due to spring manufacturing and economic considerations. limited. That is, wires that are too thin or too thick for the wire diameter normally used. When using spring wire, the spring manufacturing equipment must be changed depending on the wire diameter. No. Moreover, if a wire with an extremely thick linear shape is used, the cost will increase. Not only that, but it may also lead to an increase in weight.

[0009] Therefore, by being subject to such restrictions, the first stroke of the first cushion body The hardness of the pulling unit and the second spring unit of the second cushion body is There were times when it was difficult to make major changes.

0010

[Problem that the idea aims to solve]

Thus, conventional mattress devices form two spring units. By changing the hardness of the spring, we are able to provide different hardness, so this The cushion body formed from these spring units has a large difference in hardness. There were times when I was unable to do so.

[0011] This idea was created based on the above circumstances, and its purpose is to At least one of the two cushion bodies is constructed without using a spring unit. This creates a large difference in hardness compared to a cushion body using a spring unit. An object of the present invention is to provide a mattress device that can be used for a long time.

0012

[Means to solve the problem]

In order to solve the above problems, this invention includes a first cushion body and a first cushion body. a cushion which is polymerized into the cushion body and which is different from the first cushion body; the first cushion body and the second cushion; and an exterior body covering the body, one of the pair of cushion bodies having a predetermined thickness. An elastic foam made of a plate-shaped body with multiple accommodation holes opening on one side. a body, a coil spring accommodated in each of the housing holes, and one of the foamed elastic bodies. and an elastic sheet that is bonded to the surface and closes the opening of the accommodation hole. It is characterized by

[0013]

[Effect]

According to the above configuration, one cushion body is made of a foamed elastic body made of a plate-like body. By changing the foaming rate of this foamed elastic material, it can be applied over a wide range of areas. It becomes possible to set the hardness of the cushion body.
