Further, as described above, in the head-side mat 5A and the present embodiment in which the weight of the user is relatively heavy, the porous sheet 14 having a relatively high rigidity is laid in the region supporting the thigh of the leg-side mat 5B, An air bag 6 is attached thereon. As a result, since the air bag 6 is supported without being bent, the air bag 6 generates a push-up force due to air expansion, the pressure acts effectively on the user, and the acupuncture point is effectively pressurized, and the massage effect Can be increased.

  In the present embodiment, as shown in FIG. 10, the air supply means 7 includes an air pump 38 that generates high-pressure air to be supplied to the air bag 6, and three-way supply and supply of the high-pressure air to the air bags 6 individually. The thing comprised including the some valve A-valve G using the valve is illustrated. In this embodiment, the air pump 38 and the plurality of valves A to G are housed in the unit 39 in a box shape. 4 and 5, the unit 39 is housed in a housing portion 36 formed on the leg-side mat 5B. Therefore, since the air supply means 7 is accommodated within the thickness of the mat 5, it does not protrude from the mat 5, and an air massage function can be incorporated in a compact manner. As a result, by placing the mat 5 on the bed base 4, an air massage function can be easily added to any type of bed. Furthermore, since the air supply means 7 is covered with the mat body 12 rich in cushioning properties, the mechanical sound and vibration are reduced and the quietness around the bed can be maintained. Moreover, since the air supply means 7 is housed in the area 9 on the user's foot side of the mat 5 and is disposed at the position farthest from the user's ear, comfort can be improved.

  Moreover, since the air supply means 7 of this embodiment is housed in the raised portion 15 in which the top mat layer 12T is laminated on the main mat layer 12M, the air supply means 7 is covered with the mat body 12 having a sufficient thickness. The cushioning properties are not lowered.

  Further, as in the present embodiment, the case where the storage-type bed base 4S in which the head-side placement half frame 11 and the leg-side placement half frame 11B are formed so as to be foldable in an inverted V shape is employed. However, as shown in FIG. 8, since the air supply means 7 is housed in the mat 5 and does not produce a bulge, it can be folded smoothly and has excellent handleability. Moreover, since the air supply means 7 housed in the area 9 on the lower side of the foot is positioned in a lower position in the folded state, the air supply means 7 including the mechanical part and having a large weight lowers the center of gravity and stands up in an inverted V shape. Improve bed stability.

  The air supply means 7 is connected to each air bag 6 by an air hose 10, whereby high-pressure air sent out from the air pump 38 is supplied toward each air bag 6. In this embodiment, as shown in FIG. 10, the valves A to G and the air bags 6 corresponding to the valves A to G are individually connected by an air hose 10. However, as shown in FIG. 5, the plurality of air hoses 10 extending from the air supply means 7 are bundled together and entirely covered with a tubular cover, and are branched from the vicinity of each air bag 6. . Further, in the present embodiment, as shown in FIG. 3, the air hose 10 extending from the leg-side mat 5B and the head-side mat 5 are jointed to each other, and the neck air bag 6N and the back portion of the air hose 10 are connected to each other. Connecting devices 40, 40 that can supply air without leakage toward the air bag 6B and the air bag 6W at the waist are attached. Accordingly, the connecting devices 40 and 40 can be joined to supply high-pressure air to the whole air bag 6. When the mat 5 is removed from the bed base 4, the connecting device 40 is disconnected and the head side is removed. The mat 5 and the leg-side mat 5B can be separated.

  Air supply / exhaust to each air bag 6 is controlled by the control means 8. As shown in FIG. 10, the control means 8 of this embodiment includes a main control unit 8A for controlling the whole, an air pump control unit 8B for controlling the air pump 38 in response to a signal from the main control unit 8A, a valve A to an air valve control unit 8D for individually controlling the valves G. Further, the control means 8 of this embodiment is accommodated in the unit 39 together with the air supply means 7, and is therefore accommodated in the accommodating portion 36 of the leg-side mat 5B. Each of the valves (three-way valve) is controlled by the air valve control unit 8D, and as shown in FIG. 11, the air hose 10 continuing to each air bag 6 communicates with the air pump and the air side. It is controlled to be switchable to the open side. When the three-way valve is on the pump side and the air pump is operating, the internal pressure of the air bag 6 rises and expands, and then the internal pressure is maintained when the air pump stops. Further, when the three-way valve is switched to the open state, the internal pressure of the air bag 6 is lowered and the air bag 6 is contracted. This series of operations is repeated with a signal from the main control unit 8A, whereby the inflation and contraction motion of each air bag 6 is continuously waved to massage the user.

  The control means 8 includes an automatic operation control unit 8E that controls the automatic operation mode of each air bag 6, and an operation time control unit 8F that controls a continuous operation time. The main control unit 8A receives an air pressure sensor for detecting high-pressure air pressure supplied from the air pump 38 and an operation signal from the remote controller 41 (operation input unit) shown in FIG. The operation time data is output to the timer 42.

  Furthermore, in this embodiment, the cover 13 is mounted so as to surround the mat body 12 and the air bag 6 as a whole. The cover 13 has a bag shape that can accommodate the entire mat 5, and in this embodiment, as shown in FIGS. 4 and 6, the cover 13 is divided into a head-side mat 5A and a leg-side mat 5B. Since each of the slide fasteners 37 is openable and closable, the mat body 12 can be attached and detached. Further, the cover 13 is formed with a stretchable cloth such as a jersey, tricot, velvet, knit or the like in the contact area 16 that covers the air bag 6 at the center of the upper surface and contacts the air bag 6. Therefore, the pressure of the inflated air bag 6 is transmitted to the user without being attenuated, and an excellent massage effect is obtained. Further, since the tensile force of the cover 13 other than the contact region 16 is reduced, irregular deformation of the entire cover 13 can be suppressed, and the appearance is excellent. When a normal bed is used without using the massage function, a lay pad is laid on the cover 13 for use.
