You can warm up the 3c and use it comfortably even in winter.

[0007]

[Embodiment] The air mattress 3 is used by laying it on tatami mats in a Japanese-style room, and as shown in FIG.
It can be folded freely by connecting the two. Each of the plurality of mat parts 3a, 3b, and 3c has an air tube 1 installed therein, and the air tube 1 expands when air is supplied and contracts when air is discharged. A frame 8 made of slightly hard urethane foam (for example, specific gravity 0.075) is provided around each mat portion 3a, 3b, and 3c, and an air tube 1 is arranged in a portion surrounded by the frame 8. . A cushioning material 9 made of soft urethane foam (for example, specific gravity 0.02) is laminated on the entire upper and lower surfaces of the frame 8 and the air tube 1. A surface covering cloth 10 such as quilting is applied over the entire surface of the cushioning material 9 on the front side, and a side covering cloth 11 such as quilting is applied to the outer periphery of the frame 8 and the upper and lower cushioning materials 9. The surface covering cloth 10 and the side covering cloth 11 are integrally connected.

A plurality of mat portions 3a of the air mattress 3
, 3b, and 3c, a pump unit 5 and an operation panel 6 are provided on the mat portion 3b located in the center. A rectangular mounting hole 1 penetrating inside and outside is provided on the side of the frame 8 of the mat portion 3b.
2 is bored, and an opening smaller than this attachment hole 12 is formed in the side covering cloth 11. A case 13 in which the pump unit 5 and the operation panel 6 are provided is formed into a rectangular parallelepiped shape with a size that can be embedded in the mounting hole 12, and the case 13 has a pump unit storage section 14, a battery storage section 15, and an operation panel mounting section 16. are doing. A collar portion 17 is provided around the outer periphery of the front surface of the case 13 on the operation panel mounting portion 16 side, and a plurality of ring-shaped insertion portions 1
8 are provided in a protruding manner, and a plurality of insertion portions 18 are arranged in a straight line. The case 13 is attached to the frame 8 in the following manner. The case 13 is inserted into the mounting hole 12 from the outside of the frame 8, and the flange 17 is brought into contact with the opening edge of the mounting hole 12 via the side covering cloth 11. At this time, the opening edge 11a of the side covering cloth 11 is rolled into the attachment hole 12. And a stop bar 20 that is longer than the width of the mounting hole 12
is placed in the frame 8, a stop bar 20 is inserted into the plurality of insertion portions 18 from the side, and both ends of the stop bar 20 are locked to the inner surface of the frame 8. As a result, as shown in Fig. 1 and Fig. 2, the case 13
is attached to the frame 8 so that it does not come off. At this time, the opening edge on the outer surface side of the mounting hole 12 of the frame body 8 and the side surface covering cloth 1
A pressing plate 21 is interposed between the flange 17 and the flange 17 to reinforce the portion that abuts the flange 17 so as not to deform more than necessary.

A pump unit 5 is housed in the pump unit housing section 14 of the case 13, as shown in FIG. Pump unit 5 is air pump 2, air pump 2
The main body consists of a motor 22 that drives the valve 4, a heater section 28, and the like. The valve 4 includes an air supply valve 4a, which is a solenoid valve that opens and closes the air supply to the mat part 3a where the shoulders are located when sleeping, and an electromagnetic valve which opens and closes the air supply to the mat part 3b where the waist is located when the person sleeps. An air supply valve 4b, an air supply valve 4c which is a solenoid valve that opens and closes the air supply to the mat portion 3b where the feet are located when sleeping;
and an exhaust valve 4d which is a solenoid valve. A discharge pipe line 23 is connected from the discharge port of the air pump 2, and a heater part 28 that electrically heats the air is inserted into the discharge pipe line 23. The heater part 28 heats the air and turns it into hot air. It looks like this. This discharge pipe 23 is connected to the heater section 28
It branches into a plurality of pipes at the tip, and the branched discharge pipes 23 are connected to air supply valves 4a, 4b, and 4c, respectively,
The exhaust valve 4d is also communicated with a part of the discharge pipe 23. The air supply valve 4a is connected to the air tube 1 of the mat portion 3a through the air supply pipe 24a, and the air supply valve 4b is connected to the air supply pipe 24.
b, and the air supply valve 4c is connected to the air tube 1 of the mat portion 3c through an air supply pipe line 24c. The air supply pipe 24c is inserted through a part of the frame 8 cut out. With the air pump 2 being driven, when the air supply valve 4a is opened, air is supplied to the mat section 3a, when the air supply valve 4b is opened, air is supplied to the mat section 3b, and when the air supply valve 4c is opened, air is supplied to the mat section 3b. Air is supplied to the mat portion 3c. At this time, the heater section 28
When energized, the air is heated by the heater section 28 and hot air is supplied to the mat sections 3a, 3b, and 3c. In addition, when the air pump 2 is stopped and the exhaust valve 4d is open, when the air supply valve 4a is opened, the air from the mat section 3a is evacuated, and when the air supply valve 4b is opened, the air from the mat section 3b is evacuated, and the air supply valve 4
When c is opened, the air in the mat portion 3c is removed. Further, the battery storage section 15 houses a battery 25 that serves as a power source for driving the motor 22, heating the heater section 28, and various controls.
The operation panel 6 is provided with an opening for inserting and removing the battery 25 so as to correspond to the battery storage section 15, and a lid 26 that can be opened and closed is attached to this opening.
