An embodiment of this invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a spring unit formed by connecting a large number of coil springs 2 . The upper and lower surfaces of the spring unit 1 are covered with protective materials 4, 4, such as synthetic resin nets made of polypropylene resin, sisal, etc.
Elastic bodies 5, 5 such as urethane foam are polymerized through the polymer, and this polymer is covered with an exterior material 6. This exterior material 6 consists of an upper exterior body 7 that covers the upper surface of the polymer, a lower exterior body 8 that covers the lower surface, and a gusset plate 9 that covers the outer peripheral surface. 7 and inner cloth 13 described later
The peripheral edge of the tape edge 10 is sewn together with the tape edge 10. However, the periphery of the approximately central portion on one end in the longitudinal direction of the upper exterior body 7 is not sewn together with the gusset 9 and tape edge 10 over an appropriate length;
A fastener 11 is sewn on. A fastener 12 that engages with the fastener 11 is located on the upper surface side of the inner cloth 13 and sewn together with the gusset 9 and tape edge 10.

Therefore, this portion can be opened and closed by the fasteners 11 and 12, and a space 26 is formed between the upper exterior body 7 and the inner cloth 13.

On the other hand, the lower end of the gusset 9 is sewn together with the peripheral edge of the lower exterior body 8 and the tape edge 10. Incidentally, the upper exterior body 7 has a padding 7c such as cotton or urethane foam accommodated between a mirror fabric 7a, a nonwoven fabric, etc., and a lining fabric 7b, and these are integrally quilted. Similarly, the lower exterior body 8 has a padding 8c between the mirror fabric 8a and the lining fabric 8b.
It houses them and has been quilted into one piece. Furthermore, an inner cloth 13 is provided between the elastic body 5 located above the polymer and the upper exterior body 7 and joined to the elastic body 5. The inner cloth 13 is sewn together with the upper exterior body 7, the gusset 9, and the tape edge 10 at the peripheral portion. A flange cloth 14 is provided on the periphery of the inner cloth 13 and the lower exterior body 8, with one end sewn to each other.
The other ends of these are connected and fixed by clips 15 to coil springs 2 located around the spring unit 1 so as to wrap around the peripheral portions of the elastic bodies 5, 5. And the above fastener 11,
A presser cloth 16 is provided on the upper surface side of the approximately central portion of the inner cloth 13 in the longitudinal direction corresponding to the position where the presser cloth 16 is provided.
are sewn to provide three accommodating portions 17.

This presser cloth 16 has an appropriate width along the width direction of the pine restraint device, and is sewn to the upper surface of the inner cloth 13 at four locations along the width direction, including both ends in the length direction and two locations in the middle. The presser cloth 16 between the sewn parts is the inner cloth 13
By overlapping the inner cloth 13 compared to the upper surface of the inner cloth 13, an appropriately sized housing portion 17 is formed.
has been established. An air tube 18 is housed in one of the housing sections 17.

The air tube 18 is formed into a substantially cylindrical shape by an airtight sheet 19 made of vinyl synthetic resin, rubber, etc., and has an inlet/outlet 20 and a plug 21 at one end in the longitudinal direction for letting air in and out. There is. The air tube 18 is accommodated in and out of the housing portion 17 by opening and closing the fasteners 11 and 12.

According to the mattress device having such a structure, the air tube 18 can be freely taken in and taken out because the fasteners 11 and 12 allow the approximately central portion in the longitudinal direction of the mattress device to be opened and closed over an appropriate length. Also, this air tube 18
By filling air into the mattress device and storing it in the mattress device, a substantially central portion in the longitudinal direction of the mattress device protrudes upward along the width direction. When a user sleeps with their lower back resting against this protruding part, the air tube 18 supports the lower back comfortably, reducing the burden on the user's lumbar vertebrae and preventing large loads from being placed on the user's buttocks. It is possible to obtain a pine stress device that prevents pine stress and provides comfortable sleeping. In addition, by connecting a hose 23 connected to an appropriate pump 22 to the inlet/outlet 20 of the air tube 18 and adjusting the amount of air with the pump, it is possible to obtain the hardness of the air tube 18 that suits the user's body shape and preference. Therefore, it can be used appropriately by users of any body shape or preference. In addition, the air tube 18 is held down by a cloth 1.
6 and the inner cloth 13, the air tube 18 is held down by the pressing cloth 16, and the air tube 18 is prevented from shifting during use.
Furthermore, since three accommodating sections 17 are provided, the air tube 18 can be accommodated in the accommodating sections 17 at appropriate positions according to the body shape of the user.

Note that this invention is not limited to the above-mentioned embodiment; for example, the air tube 18 may be formed by the housing section 17 formed of the inner cloth 13 and the presser cloth 16.
However, it may be accommodated directly between the inner cloth 13 and the upper exterior body 7.

Further, in the above embodiment, the shape of the air tube 18 is approximately cylindrical, but the shape is not limited to this, and any shape may be used as long as it is an elongated tube. Furthermore, fasteners 11 and 12 of appropriate length were provided approximately at the center in the longitudinal direction of the pinerest device, but these fasteners 11 and 12
may be provided over the entire length of one end of the pinerest device. In addition, in the above embodiment, elastic bodies are superposed on the upper and lower surfaces of the spring unit,
Although the polymer is covered with an exterior material, the present invention is not limited to this, but it is also possible to provide a spring unit on the frame like a bottom pine tress, polymerize an elastic body to this spring unit, and cover them with an exterior material. It is also possible to do something like this.

[Effect of idea]

As described above, this invention consists of a spring unit by connecting a large number of springs in a flat plate shape, polymerizing an elastic body on at least one of the upper and lower surfaces of the spring unit, and applying this polymer to the exterior surface. In the pine tress device constructed by covering the exterior material, a substantially central part in the longitudinal direction of the exterior material is formed to be openable and closable, an inner cloth is provided between the elastic body on one surface and the exterior material, and the approximately inner A presser cloth was provided on the upper surface side of the approximately central portion of the cloth in the longitudinal direction, and the inner cloth and the presser cloth formed a housing section along the width direction of the pinerest device, and the air tube was housed in the housing section so as to be freely put in and taken out. Therefore, this air tube supports the user's lower back comfortably, reducing the burden on the user's lumbar vertebrae, preventing the load from concentrating on the user's buttocks, and keeping the user in the correct sleeping position. This makes it a comfortable pine rest device.
