It is said to be the storage part of. Reference numeral 34 in the drawing denotes an operation panel attached to the side end surface.

The cushion layer in the body 1 includes a first cushion layer 11 arranged on a receiving plate 10 made of a relatively hard and plastic material such as expanded polypropylene, and a second cushion layer adhered and fixed on the first cushion layer 11. 12, a third cushion layer 13 interposed between the diaphragm 2 and the air bag 5, a fourth cushion layer 14 that comes into contact with the inner surface of the cover 4,
The fifth cushion layer 15 sewn on the cover 4 at the same time
It consists of a total of 5 layers. The second cushion layer 12 has a one recess formed in a part, the motor M ₂
And an eccentric weight 23 attached to the output shaft, and a vibration unit in which the motor M ₂ is attached to the lower surface of the vibration plate 2 by a mounting frame 28 via a vibration-proof rubber 29 is provided in the recess. It is contained.

For the air bag 5 which is connected to the pump P and inflates when air is pumped from the pump P, two sheets to which a vinyl chloride sheet having a weldability and a nylon cloth having a high tensile strength are adhered are prepared. , Which is formed by joining both sheets with vinyl chloride surfaces facing each other with a welder, and has mounting holes 50, 50 at four corners.
Is attached to the frame 3 by engaging the pair of attachment holes 50, 50 with the pair of hooks 38, 38 formed in the one connecting piece 30 in the above, and is received on the central portion of the second cushion layer 12. The pair of hooks 3 formed on the other connecting piece 30 of the frame 3 are provided in the remaining two mounting holes 50, 50 which are arranged via the plate 16.
Rubber bands 51, 51, one end of which is locked, are connected to 7, 37.

The pair of protrusions 20, 20 on the diaphragm 2 are
The third cushion layer 13, which is attached to the lower surface thereof,
It is placed on the air bag 5 via 13. Here, as is apparent from the above description, the air bag 5 and the diaphragm 2 are pivotally supported on different sides of the frame 3, and the respective free end sides are superposed on each other.
When the air bladder 5 is inflated, the air bladder 5 is inflated so as to rotate around the connection point with the one connection piece 30, and the diaphragm 2 together with the vibrating unit is hinged in accordance with the expansion of the air bladder 5. The air bag 5 moves in a direction opposite to the rotation direction while bending the air bag.

The fifth cushion layer 15 attached to the cover 4 by sewing the cover 4 to the pressing cloth 17 is positioned immediately above the air bag 5, and the cushion layer 15 in the cover 4 is provided. A pair of acupressure balls 7, 7 are attached to the formed portion at intervals of about 70 mm. As is apparent from FIG. 1, the acupressure ball 7 is provided so as to avoid the protruding pieces 20 and 20 of the diaphragm 2. Reference numeral 18 in the figure is a pressing plate for reinforcing the caulking attachment portion of the acupressure ball 7.

The cover 4 covering the entire first to fourth cushion layers 11 to 14 has the operation panel 34 at one end side of the body 1.
The other end is openable and closable by a fastener 40 for attaching and detaching the battery 6.

FIG. 5 shows a circuit diagram, and FIG. 6 shows a piping system for the pump P and the air bladder 5. The motor M ₁ that drives the pump P is connected to the battery 6 via the normally open terminal NO of the pressure switch SW ₁ , and the motor M ₂ in the vibration unit is the pressure switch S 1.
It is connected to the battery 6 via the normally closed terminal NC of W ₁ and the switch SW ₂ . The pressure switch SW ₁ can be switched only while receiving an operation input, and is normally closed terminal N when the pressure switch SW ₁ is released.
The C side is connected to the battery 6.

Further, a T-shaped branch pipe 59 is inserted in the middle of a pipe 58 connecting both the pump P and the air bladder 5 to connect the exhaust unit 55. The exhaust unit 55 has a built-in safety valve 56 that exhausts air when the pressure exceeds a certain level, and rapidly exhausts the air in the air bag 5 by receiving an operation input.

As is clear from FIG. 4, the vibration massage machine has a thin central portion and both side end portions projecting forward to increase the thickness, and both side end portions are long. In this direction, the thickness is gradually increased in one direction to have directionality.
It is used by being placed on the floor surface or arranged on a chair, particularly a backrest surface of an automobile seat. At this time, since the shape of the body 1 is given directionality, the installation direction will not be wrong. In use, the lower part of the back is inserted between the both side ends projecting forward, and the back is brought into contact with the front surface of the central part where the acupressure ball 7 projects. The body 1 bends so as to conform to the backrest surface of the chair according to the load received at this time, and since the thickness of the central portion is thin, the human body B does not float up from the backrest surface of the chair.

Now, when the air bag 5 is not inflated and the diaphragm 2 is not vibrated, the air bag 5 is in a contracted state.
The acupressure balls 7 received by the receiving plate 16 via the abutments surely hit the “pots” located on both sides of the spine on the back surface of the human body B.
When the switch SW ₂ is operated to operate the vibration unit in this state, the vibrations of the pair of protrusions 20 and 20 of the diaphragm 2 are transmitted to the human body B via the cushion layers 14 and 15 and the acupressure balls 7.

When the pressure switch SW ₁ is switched to the normally open contact NO side by applying an operation input, the pump P is driven by the motor M ₁ and air is pumped to the air bladder 5. As a result, the air bag 5 is inflated and the front surface of the central portion of the cover 4 is projected forward to support the waist of the human body B. At this time, the inflation of the air bladder 5 is made so as to rotate as a whole around the connecting portion with the one connecting piece 30 in the frame 3 as described above. The diaphragm 2 that follows the expansion of the air bag 5 moves so as to rotate around the hinge piece 21 connected to the other connecting piece 30, so that the expansion of the air bag 5 is hindered by the diaphragm 2. There is no such thing and it expands smoothly. When the air bladder 5 is inflated, the tip of the protrusion 20 of the diaphragm 2 escapes from the vicinity of the top of the air bladder 5 as shown by the chain line in FIG. And the acupressure ball 7 only contact the human body B, and the acupressure ball 7 located on the top of the air bag 5 to clarify the treatment position for the user is also in the cushion layer 15 and the air bag 5. Since it is embedded in the structure, it does not have the feeling of being foreign and is hard, and exhibits a lumbar support function with a good usability and a high fit. Although the protruding piece 20 of the diaphragm 2 escapes from the top of the air bag 5 when the air bag 5 is inflated, the cushion layer 14 as a cushioning body exists between the protruding piece 20 and the air bag 5. Therefore, the protruding piece 20, which is regarded as a substantially rigid body, in particular, the edge thereof does not damage the air bag 5.

When the pressure switch SW ₁ is released, the pressure switch SW ₁ returns to the normally closed contact NC side, so the pump P is stopped. At this time, if the switch SW ₂ is turned on, vibration occurs. Although the massage is restarted, since the protruding piece 20 of the diaphragm 2 follows the expansion of the air bag 5 well, the vibration is sufficiently transmitted to the human body B even in this state. Further, the cushion layer 14 located between the protrusion 20 and the air bag 5 is
Noise generated between the projecting piece 20 and the air bag 5 is prevented.

When the exhaust unit 55 is operated, the air in the air bag 5 is deflated, so that the air bag 5 contracts. At the time of this contraction, the presence of the rubber band 51 pulling the free end side of the air bag 5 causes the air bag 5 to settle at a predetermined position.
The air bag 5 will not be displaced even if it is repeatedly expanded and contracted.

[Effects of the Invention] As described above, in the present invention, one ends of the air bag and the diaphragm that are overlapped with each other are pivotally supported on different sides of the frame, and the other ends that are free ends are overlapped with each other. The expansion of the air bladder and the follow-up of the diaphragm to this expansion are centered at the pivotal positions on the different sides of the frame. The air bag smoothly inflates without hindering it. Therefore, the load of the air pressure feeding means on the air bag is small, and the small and low power consumption air pressure feeding means is sufficient. The displacement is less likely to occur, and moreover, the diaphragm can follow the expansion of the air bag well, and the diaphragm does not suppress its own vibration. And surely vibrate Is to be transmitted. In addition, the amount of overlap between the air bag and the diaphragm changes when the air bag contracts and when it expands, and the amount of overlap when inflating decreases. It is possible to suppress the feeling of hard foreign matter.
