2. Description of the Related Art In recent years, air mattresses have been provided in which a mattress is equipped with an air tube that can be expanded and contracted, and air is supplied to the air tube using an air pump. The operation of driving and stopping the air pump of such an air mattress and the operation of opening and closing the valve are performed by a remote control such as a wired remote control. In addition, a commercial power source is used as a power source to drive the air pump, etc.

0003

By the way, air mattresses for Japanese-style rooms are laid on tatami mats when in use, but when not in use, they are folded and stored in a closet or the like. However, in the case of the above conventional example, the cord for the remote control for remote control operation protrudes from the air mattress, and the cord for supplying power also protrudes from the air mattress, causing the problem that the cord gets in the way when handling the air mattress. be.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a drive unit for an air mattress that allows easy handling of the air mattress without unnecessary cords. It is there to provide structure.

around the urethane foam (for example, specific gravity 0.
075) is provided, and the 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 to the entire surface of the cushion material 9 on the front side, and the frame body 8
A side covering cloth 11 such as quilting is attached to the outer periphery of the upper and lower cushioning materials 9, and 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 and a motor 22 that drives the valve 4. The valve 4 is attached to the mat part 3 where the shoulders are located when sleeping.
Shoulder solenoid valve 4a that opens and closes the air supply to a, waist solenoid valve 4b that opens and closes the air supply to the mat part 3b where the lower back is located when sleeping, and the lower back solenoid valve 4b which opens and closes the air supply to the mat part 3b where the feet are located when sleeping It is composed of a foot solenoid valve 4c that opens and closes the air supply, and an exhaust solenoid valve 4d. Shoulder solenoid valve 4a, waist solenoid valve 4b
The leg electromagnetic valve 4c and the discharge port of the air pump 2 are communicated with each other through a communication line 23, and the communication line 23 is communicated with the exhaust electromagnetic valve 4d. The shoulder solenoid valve 4a is connected to the air tube 1 of the mat part 3a through an air supply pipe 24a, and the waist solenoid valve 4b is connected to the air tube 1 of the mat part 3b through an air supply pipe 24b. ,
The foot solenoid valve 4c is connected to the air tube 1 of the mat portion 3c through an air supply pipe 24c. The air supply pipe 24c is inserted through a part of the frame 8 cut out. When the shoulder solenoid valve 4a is opened while the air pump 2 is being driven, air is supplied to the mat part 3a, and the waist solenoid valve 4b is opened.
When opened, air is supplied to the mat portion 3b, and when the foot solenoid valve 4c is opened, air is supplied to the mat portion 3c. Also, with the air pump 2 stopped and the exhaust solenoid valve 4d open, opening the shoulder solenoid valve 4a will bleed out the air from the mat section 3a, and opening the waist solenoid valve 4b will drain the air from the mat section 3b. When it is pulled out and the foot solenoid valve 4c is opened, the mat part 3
The air in c is removed. Further, the battery storage section 15 stores a battery 25 that serves as a power source for driving the motor 22 and various controls, and the operation panel 6 has an opening 29 for inserting and removing the battery 25 so as to correspond to the battery storage section 15. A lid 26 that can be opened and closed is attached to the opening 29.

The operation panel 6 is attached to the operation panel mounting portion 16 of the case 13 so as to close the front opening of the case 13, and a printed circuit board 27 is attached to the inside of the case 13 of the operation panel 6.

Effects of the Invention As described above, the present invention embeds a pump unit having an air pump, valves, etc. in the side of an air mattress, and embeds an operation panel on the outside of the pump unit for operating the air pump and opening/closing the valves. Since the control panel is exposed from the side of the air mattress,
It can be operated without wiring extra cords like conventional remote control operations, and in addition, it can be operated from the control panel located at a fixed position on the side of the air mattress, so there is no need to search for the control panel even when lying down. It is easy to operate, and since there is a battery compartment on the side of the pump unit that stores the battery that serves as the power source, it can be driven from the battery, eliminating the need for a power supply cord like in the past. In addition to not requiring a cord for the remote control, it is easy to handle as there is no cord protruding from the air mattress.Furthermore, the battery can be installed in the part of the control panel that corresponds to the battery compartment. Since an opening for putting in and taking out the battery is provided and a lid that can be opened and closed is attached to the opening, the battery can be easily put in and taken out by opening and closing the lid using the operation panel.
