DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a cushion-type treatment machine that has a built-in electric treatment device such as a vibrator and is used by being set on a floor, a chair, or the like.

[Background Art] Cushion-type treatment machines include those with a built-in vibrator and those equipped with an air bag that is inflated by air sent from a pump. However, conventional devices of this type have the following problems. That is, U.S. Patent No.
4136685 specification and Utility Model Application Publication No. 57-29232, etc., when storing not only the treatment member but also its power supply unit, drive member, etc. in the cushion, the overall thickness of the cushion must be Because it was thick, when placed between the body and the back of a chair or the floor, it felt strange and uncomfortable to use. This means that the user's sitting position will be in front of the position without the cushion, and when used as a car seat, this misalignment of the seating position may become a hindrance to driving, and the user will have to take the trouble of adjusting the seat position. I invite you. Furthermore, in the case shown in the above-mentioned publication, since the rigid body such as the power source is housed in the center of the cushion, the flexibility required for the cushion is lost, and the cushion does not fit the shape of the body, giving a very strange feeling. It has become a thing.

[Object of the Invention] The present invention has been made in view of the above points, and its purpose is to provide a cushion-type treatment device that has a high fit to the body, does not cause any discomfort, and is comfortable to use. It is on offer.

[Disclosure of the invention]

Accordingly, the present invention has a case having a U-shaped cross section with side walls protruding toward the front side at both ends, and a power supply unit and a driving member for the treatment member are provided in the both ends where the side walls are provided. A pump as a member and an operating section are disposed, and a treatment member consisting of an air bag to which air is pumped from the pump is disposed at a central portion between the both side walls, and this central portion is used as a treatment section. Thick components such as the power supply and pump are placed within the side walls on both sides, which enhances the feeling of support, and the treatment components are placed in the center. This allows the thickness of the part to be made thinner.

The present invention will be described in detail below based on the illustrated embodiment. This cushion-type treatment machine has a vibrator function by vibrating a diaphragm 2 and an air bag 5 in a case body 1 as a cushion. When inflated, it provides a lumbar support function, a so-called lumbar support function.

First, let's start with the case 1, which is composed of multiple cushion layers 11 to 15, a frame 3, and a cover 4 made of sheet material. By forming the side walls that protrude to the side, it is configured as a U-shaped cross section, with the thickness at both ends where the side walls are provided being thicker and the thickness at the center between the side walls being thinner. . The frame 3 is made of a relatively flexible plate-like material such as polypropylene, and the ends of both sides, both of which are cylindrical, are integrally connected by connecting pieces 30, 30, respectively. It is configured as. Here, as is clear from FIG. 6, the cylindrical parts 31 and 32 at both end portions are formed by folding the both end portions of the frame 3 that protrudes forward toward the back. It is fixed with screws 39 so as to maintain its cylindrical shape.

A hook 38 is integrally provided on one connecting piece 30 of the frame 3, and a diaphragm 2 is integrally provided on the other connecting piece 30 via hinge pieces 21, 21. A diaphragm 2 fixed to the back side of the oscillation unit, which will be described later, has a tip portion divided into two parts and a U-shape from the front.
In addition, both the cylindrical portions 31 and 32 at both end portions of the frame 3
One of the cylindrical portions 31 is connected to a battery 6 as a power source.
A snap piece 33 for holding the battery 6 is integrally provided in the attachment/detachment opening. As shown in FIG. 3, the other cylindrical portion 32 serves as a housing portion for a pump P and a motor _M1 for driving the same, and also serves as a housing portion for an exhaust unit 5.
5, pressure switch SW ₁ , switch SW ₂ and other operating members, and an external power jack 60. In particular, the operating button 34 for the exhaust unit 55
The operation button 34 for the pressure switch SW ₁ is provided integrally with the frame 3. In the figure, 35 is an operation panel attached to the side end surface.

The cushion layer in the container body 1 includes a first cushion layer 11 disposed on a receiving plate 10 made of a relatively hard and plastic member such as foamed polypropylene, and a second cushion layer adhesively fixed thereon. 12, a third cushion layer 13 disposed on the central portion of the second cushion layer 12, a fourth cushion layer 14 that comes into contact with the inner surface of the cover 4;
The fifth cushion layer 15 is sewn to the cover 4 at the same time, making up a total of five layers. The second cushion layer 12 has recesses formed in a plurality of places, and serves as a holder for holding the motor M ₂ via an eccentric weight 23 and a vibration isolator 29 attached to the output shaft of the motor M ₂ . A vibration unit consisting of frames 27 and 28 and riveted to the lower surface of the vibration plate 2 is housed in this recess, and a pressure sensitive switch _SW3 is also housed therein. The support plate 17 of the pressure sensitive switch SW ₃ is sandwiched between the first cushion layer 11 and the second cushion layer 12.

The third cushion layer 13, which is disposed on the center of the second cushion layer 12 and covers the pressure-sensitive switch SW ₃ , is connected to the pump P and has air pumped therethrough. Inflatable air bag 5
are arranged through the receiving plate 16, and a pair of protrusions 2 of the diaphragm 2 are placed on the air bag 5.
0 and 20 are listed. When the air bag 5 is inflated, the diaphragm 2 moves together with the vibration unit while bending the hinge piece 21 in accordance with the expansion of the air bag 5.

A fifth cushion layer 15 is sewn simultaneously on the cover 4 and is positioned directly above the air bag 5, and a portion of the cover 4 where this cushion layer 15 is provided has a fifth cushion layer 15 that protrudes to the outside. Acupressure ball 7 is attached. When the air bag 5 is inflated, the acupressure ball 7 is pushed and largely protrudes forward.

A cover 4 that covers the entire first to fourth cushion layers 11 to 14 is fixed at one end of the container body 1 by the operation panel 35, and at the other end is used for attaching and detaching the battery 6. It can be opened and closed by a fastener 40.

FIG. 7 shows the piping connection between the pump P and the air bag 5. A T-shaped branch pipe 59 is inserted in the middle of a pipe 58 connecting the two, and the exhaust unit 55 is connected thereto. This exhaust unit 55 has a built-in safety valve 56 that exhausts the air when the pressure exceeds a certain level, and also quickly exhausts the air in the air bag 5 by pushing in a button 34 that is integrated with the frame 3. It is something.

As is clear from Fig. 4, this cushion-type treatment machine is thin at the center and thicker at both ends, which protrude forward. The height increases in one direction, making it directional, and can be placed on the floor or on the back of a chair as shown in Figures 8 and 9. It is placed and used. At this time, vessel 1
Since the shape has directionality, there is no need to install it in the wrong direction. When in use, the lower part of the back is placed between the two end portions that protrude forward, and the back is brought into contact with the front surface of the central portion from which the acupressure ball 7 protrudes. Depending on the load it receives at this time, the body 1 bends to follow the backrest surface of the chair 9, as shown in FIG. There is no such thing as floating away.

Now, if the operation button 34 is pressed and the pressure switch _SW1 is switched to the normally open contact NO side as shown in FIG. 5, the pump P will be driven by the motor _M1 .
Air is forced into the air bag 5. As a result, the air bladder 5 expands, causing the central front surface of the cover 4 to protrude forward to support the waist of the human body B, and press the acupressure ball 7 against the human body B. The position of the acupressure ball 7 is set so as to press the vicinity of the third lumbar vertebra of the human body B. When the operator releases the operation button 34, the pressurizing switch _SW1 returns to its normal state and switches to the normally closed contact NC side, thereby stopping the pump P. When it is desired to remove air from the air bag 5, the exhaust unit 55 can be operated.

Pressure switch SW ₁ When the normally closed contact is on the NC side,
When the switch SW ₂ is turned on and the pressure-sensitive switch SW ₃ is turned on by applying a load to the vessel body 1, the motor _M2 is operated to generate vibrations in the diaphragm 2. At this time, since the pair of protrusions 20, 20 on the diaphragm 2 are both located behind the acupressure balls 7, 7, the diaphragm 2 by the oscillating unit
The vibrations are surely delivered to the human body B via the acupressure ball 7.

〔Effect of the invention〕

As described above, in the present invention, the power supply section, the pump that is a driving member of the treatment member, and the operation section are arranged in both ends where the side walls are provided, and air is supplied from the pump to the center between the both side walls. A treatment member comprising an air bag to which air is pumped is arranged,
Although it has thick components such as the pump as well as the power supply section, these thick components are housed at the side ends with upright side walls that enhance the feeling of support. A treatment member consisting of an air bag through which air from the pump is pumped is disposed, and the thickness of the central part between both side walls constituting the treatment section can be kept thin, thus reducing the fit to the body. It has a high level of functionality, does not feel strange, and is comfortable to use.
