Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a vibrating pine surger equipped with an air cushion.

[Background technology]

A vibrating pine surge machine with an air cushion is disclosed in Japanese Utility Model Application Publication No. 59-156578. This is a device in which a vibrating member is placed on top of an air bag that can be expanded and deflated, but since the vibration unit itself that performs the vibration drive is placed on top of the air bag, the air bag is inflated. In this case, there was a problem that the vibration unit felt rough and painful when it touched the human body, and that it was uncomfortable to use because the vibration unit was thick as a whole.

[Purpose of the invention]

The present invention has been made in view of these points, and its purpose is to provide a vibrating pine surger with an air cushion that is comfortable to use and does not cause discomfort due to the vibrating member even when the air bag is inflated. It is on offer.

[Disclosure of the invention]

However, the present invention provides an air bag that can be expanded and deflated;
A vibrating member is characterized in that the vibrating member consists of a vibrating unit disposed in a place where there is no air bag, and a vibrating plate located on the surface of the air bag and vibratingly driven by the vibrating unit. , so that only the diaphragm driven by vibration is positioned above the air bag.

The present invention will be described in detail below based on the illustrated embodiment. This vibrating massage machine with an air cushion has a vibrator function by vibrating a diaphragm 2 in a case body 1 as a cushion, and an air cushion. A lumbar support function, a so-called lumbar support function, is provided by an air cushion that inflates the bag 5.

First, I will explain the container body 1 as a housing. It is composed of multiple cushion layers 11 to 15, a frame 3, a cover 4 made of sheet material, etc., and has a U-shaped cross section in one direction. To form a mold, the center part is thinner and the side edges are thicker. The frame 3 is made of a relatively flexible plate-shaped 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, the respective cylindrical parts 31 and 32 at both side ends are formed by folding the both side ends of the frame 3 that protrudes forward toward the back, as is clear from FIG. 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. The diaphragm 2, to which a oscillating unit to be described later is fixed to the back side, has a front end divided into two parts and a U-shape from the front. In addition, the two cylindrical portions 31 at both ends of the frame 3,
One of the cylindrical portions 31 of the cylindrical portions 32 is a storage portion for a battery 6 as a power source, and a snap piece 33 for holding the battery 6 is integrally provided in the opening for attachment and detachment. The other cylindrical portion 32 has a pump P and a motor for driving it, as shown in FIG.
It serves as a storage area for the exhaust unit 55, pressurizing switch _SW1 , switch _SW2, and other operating members _, as well as an external power jack 60. In particular, the operation button 34 for the exhaust unit 55 and the operation button 34 for the pressure switch _SW1 are integrally provided on 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.

The fifth cushion layer 15, which is sewn simultaneously on the cover 4, is located directly above the air bag 5, and the portion of the cover 4 where this cushion layer 15 is provided has a portion that protrudes to the outside. An acupressure ball 7 is attached. When the air bladder 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 by the operation panel 35 at one end of the container 1, and is used for attaching and detaching the battery 6 at the other end. It can be opened and closed by a fastener 40.

FIG. 7 shows a piping system 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 performs exhaustion when the pressure exceeds a certain level, and a button 3 that is integrated with the frame 3.
By pushing in the air bag 4, the air inside the air bag 5 is rapidly exhausted.

However, as is clear from Fig. 4, this vibrating pine surge machine with air compression is thin in the center and thicker at both ends, protruding forward. Both parts have directional properties in which the thickness increases in one direction in the longitudinal direction, and are used by being placed on the floor or placed on the backrest of a chair. Ru. At this time, since the shape of the container body 1 has directionality, there is no mistake in the installation direction. When in use, the lower part of the back is placed between the two end portions that protrude forward, and the front surface of the central portion from which the acupressure ball 7 protrudes is brought into contact with the back. Since the container body 1 bends along the backrest surface of the chair according to the load received at this time, and because the thickness of the central part is thin, the human body B will not float off the backrest surface of the chair.

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. Even when the air bag 5 is inflated, the protrusions 20, 20 of the diaphragm 2 are attached to a part of the surface of the air bag 5.
Since there is only an interposition, the air cushion effect of the air bag 5 will not be impaired by the rugged feeling caused by a rigid member such as a vibration unit.

When pressure switch SW ₁ is on the normally closed contact NC side, if switch SW ₂ is turned on and pressure-sensitive switch SW ₃ is turned on by applying a load to body 1, motor M ₂ will turn on. It operates to generate vibrations on the diaphragm 2. At this time, the diaphragm 2 is placed on the air bag 5.
Since the pair of protrusions 20, 20 are located behind the acupressure balls 7, 7, the vibration of the diaphragm 2 caused by the vibration unit inflates the air bag 5. It is reliably transmitted to the human body B regardless of whether or not it is caused.

〔Effect of the invention〕

As described above, in the present invention, only the vibration-driven diaphragm is placed on the surface of the air bag, so even when the air bag is inflated, there is no rough feeling and it is comfortable to use. Moreover, since only a thin diaphragm overlaps the air bag, the thickness can be reduced, and in this respect, it is also easy to use.
