Since the amount of air supplied from the air compressor operated based on the music signal varies depending on the input rate of the music signal, the internal pressure of the air bag may not rise to a predetermined pressure within a predetermined time. Such a state continues to some extent when the state where the input rate of the music signal is low continues.

However, according to the invention of claim 6, when the pressure of the air bag does not reach the predetermined pressure within the predetermined time, the air is evacuated from the air bag. Can be removed, and the inflation and deflation of the air bag can be added.

According to a seventh aspect of the present invention, in the fifth or sixth aspect, the drive signal applying means has a filter amplifier, and the gain of the amplifier is increased as the detected pressure of the pressure sensor increases. It is characterized by the following.

In a diaphragm type air compressor for supplying air to an air bag, the internal pressure of the air bag increases and the pressure in a pump chamber formed facing the diaphragm also increases, and the pressure suppresses the movement of the diaphragm.

The vibrator 59 is housed in the space between the E-shaped iron cores 56. The vibrator 59 is configured such that connection screws 60 provided at both ends in the vibration direction are inserted through the pair of inner and outer operation plates 54 and 55, and nuts 61 are screwed onto these screws 60 to tighten them. Are mounted and supported over a pair of diaphragms 51, and are provided so as to be reciprocally movable in the axial direction together with the diaphragms 51. The vibrator 59 is formed by attaching connecting screws 60 to both ends in the longitudinal direction of a frame 63 made of synthetic resin, and attaching a pair of permanent magnets 64 between these screws 60. The permanent magnet 64 is magnetized in the thickness direction.

The excitation coil 58 of the drive mechanism 52 includes:
A bass component or a commercial power signal extracted from the music signal is selectively applied as a drive signal. By the application of the drive signal, an alternating magnetic field is generated at the magnetic pole of the E-shaped iron core 56, and the vibrator 59 is driven by the magnetic attraction / repulsion acting between the magnetic field and the permanent magnet 64 as shown in FIG. The pump means 23 is driven by being vibrated in the middle and vertical directions.

The pair of auxiliary frames 53 are provided with the diaphragm 5.
The pump chamber 62 is formed so as to cover and cover the diaphragm 1. A frame cover 63 is attached to the auxiliary frame 53, and a discharge chamber 64 is formed between them. Both auxiliary frame bodies 5

And a suction valve 66 for opening and closing
A discharge hole 6 provided in communication between the pump chamber 62 and the discharge chamber 64;
A discharge valve 68 that opens and closes 7 is mounted. Suction valve 6
6 opens when the volume of the pump chamber 62 increases, and closes when the volume of the pump chamber 62 decreases. Conversely, the discharge valve 68 closes when the volume of the pump chamber 62 increases and opens when the volume of the pump chamber 62 decreases.

Therefore, the vibrator 59 of the electromagnetic drive mechanism 52 is driven by the vibrating (reciprocating) operation, for example, as shown in FIG.
(B) The diaphragm 5 which is moved to the lower middle side and is lower in FIG.
1 is deformed by being pushed downward, whereby the volume of the lower pump chamber 62 in the figure is reduced and the air in the pump chamber 62 is compressed. Suction valve 6
5 closes the corresponding suction hole 65, and the pressure of the compressed air pushes the lower discharge valve 68 to open the corresponding discharge hole 67. Therefore, FIG.
High-pressure air in the middle and lower pump chambers 62 flows out to the lower discharge chamber 64 through the discharge holes 67.

At the same time, the upper diaphragm 51 in FIG. 2 (B) is pulled downward and deformed, so that the volume of the upper pump chamber 62 is enlarged and the internal pressure is reduced. Therefore, the suction valve 6 of the auxiliary frame 53 on the upper side in FIG.
6 opens a corresponding suction hole 65, and FIG.
(B) The discharge valve 68 on the middle upper side corresponds to the discharge hole 67
2B, outside air flows into the upper pump chamber 62 in FIG. 2B through the upper suction hole 65.

Next, when the polarity of the alternating magnetic field of the E-shaped iron core 56 changes, the vibrator 59 is moved upward in FIG. 2B, so that the lower pump chamber 62 in FIG. , The lower suction valve 66 facing the pump chamber 62 opens, and the lower discharge valve 68 closes. At the same time, FIG.
The volume of the middle upper pump chamber 62 is reduced, and the upper suction valve 66 facing the pump chamber 62 is closed and the upper discharge valve 68 is opened. Therefore, the high-pressure air compressed in the pump chamber 62 on the upper side in FIG. 2B flows out to the discharge chamber 64 on the upper side in FIG.

Such a pump operation is performed by the excitation coil 58
Are repeated with the vibration of the vibrator 59 which is moved by the alternating magnetic field generated in response to the drive signal supplied to the drive signal.
The compressed air that has flowed out into the upper and lower discharge chambers 64 in FIG. 2B as described above is supplied therefrom via the air supply pipe 64a (only one is shown) to the pulsation buffer filter tank 75 shown in FIG. Supplied to In the example shown in FIG. 2, the outside air is directly taken into the pump chamber 62.
A cover that forms a suction chamber facing the suction valve 66 is attached to the outer surface of the auxiliary frame 53 so as to communicate the suction chamber with the storage chamber 41a. The air may be temporarily taken into the storage chamber 41a and then guided to the suction chamber 41a while cooling the electromagnetic drive mechanism 52, and air may be sucked into the pump chamber 62 from the storage chamber 41a.

The housing 41 of the air compressor 35 having the above-described structure is provided with a plurality of mounting portions 69 facing outward.
Are protruded integrally. The air compressor 35 is attached to the base 15 by tightening the screws 70 passing through the mounting portions 69 and the nuts 71 screwed thereto with the mounting portions 69 being in direct contact with the back surface of the base 15 of the seat portion 12. It is directly attached.

The pressure sensor 36 is provided in an air supply path (not shown) from the filter tank 75, which is the discharge section of the air compressor 35 having the above-described structure, to the air bladders 3-5. To detect the internal pressure. This detected pressure signal is supplied to the control device 31. Control device 31
Determines from the detected pressure signal whether or not the internal pressure of the air bladders 3 to 5 has reached the intensity of the pneumatic massage set by the remote controller 6, and if it is determined that the predetermined pressure has been reached. The rotary valve 37 is controlled so as to exhaust air from the air bag.

The rotary valve 37 has an air supply port communicating with the discharge portion of the air compressor 35 and the air bags 3 to 3.
5 and a plurality of distribution ports individually corresponding to 5 and one exhaust port. The valve 37 selectively connects the distribution port at a position corresponding to the air bag requiring air supply to the air supply port according to the position of the distribution valve rotated by the motor drive, and simultaneously connects the other distribution ports to the air supply port. It is adapted to communicate with the exhaust port. The operation of the motor of the rotary valve 37 is controlled by the control device 31 according to the operation mode of the pneumatic massage manually set by the remote controller 6.

Air bags 3 to 5 are individually connected to the respective distribution ports of the rotary valve 37 via air supply pipes (not shown). In this connection, the pair of air bladders 3 are connected so that air supply and exhaust are performed simultaneously, and similarly, the other pair of air bladders 4 are connected so that air supply and exhaust are performed simultaneously.

The components of the above described acoustic system 7 and massage system 8 except for the sound source 21, the speaker 23 and the air compressor 35 form a drive unit 73 and are hand-woven, and this unit 73 is shown in FIG. Bottom plate 12 attached across both armrests 11 of seat 12
a.

In the chair-type massage machine 1 having the above-described structure, the input operation of the remote controller 6 causes
When a setting is made to perform a massage operation using this music signal while reproducing the music signal, the sound source 21
All of the music signals output from the audio amplifier 22
Is supplied to both speakers 23 and reproduced.
You can relax while listening to music and receive the following massage. In this case, if necessary, the type of the sound source 21 can be selected in the input operation of the remote controller 6, so that the favorite music can be heard.

In this mode of use, the switch 33 is switched so as to supply a music signal to the filter amplifier 32. Therefore, the filter amplifier 32 extracts the bass component from the music components supplied thereto and amplifies it. This bass component is applied as a drive signal for the air compressor 35 to the excitation coil 58 of the electromagnetic drive mechanism 52 via the control device 31.

As a result, the oscillator 59 of the electromagnetic drive mechanism 52 is reciprocated in accordance with the low-frequency component to operate the pump, and the air specified by the remote controller 6 from the filter tank 75 via the rotary valve 37 is operated. Air is supplied to the bag, and the air bag is inflated.
The treatment site of the occupant corresponding to the inflated air bag is pressed. Thereafter, as the air distribution is switched by the rotary valve 37, for example, air is supplied to another air bag, and at the same time, the air bag that has been inflated up to that time is supplied to the exhaust port of the rotary valve 37. Communicated. Therefore, as the air in the air bag is exhausted, the compressed treatment site is relaxed.

The pneumatic massage can be applied to the occupant by the inflation / deflation of the air bag as described above.

In this massage, the air compressor 35 directly attached to the base 15 of the seat 12
It is driven only when air supply is required. When the compressor 35 operates, a vibration corresponding to the reciprocation of the vibrator 59 is inevitably generated, and the vibration is directly transmitted to the base 15. Therefore, the entire seat portion 12 is vibrated, and a vibration massage can be performed for a seated person on the seat portion 12. The arrow in FIG. 2B indicates the vibration direction.

Accordingly, the chair-type massage machine 1 having the above-described structure is provided.
When using a massage, an air massage using at least one of the air bladders 3 to 5 and a vibration massage using the air compressor 35 which is an air supply source of this massage as a vibration source are simultaneously provided to the occupant. Can be applied. Then, as described above, the same air compressor 35 can share the air supply source for any one of the air bladders and the vibration source of the base 15 of the seat 12. Therefore, both the massages can be realized with a simple configuration.

Moreover, the music signal output from the sound source 21 is
The pump frequency is applied to the electromagnetic drive mechanism 52 of the air compressor 35 as its drive frequency, and the oscillator 59 of the compressor 35 is tuned to the bass component of the music signal and reciprocates to perform a pump operation. Not a target. Therefore, it is possible to prevent the occupant from getting used to the vibration massage.

Further, by driving the air compressor 35 by applying the above-described bass component, the inflation of the air bag supplied through the rotary valve 37 causes a pulse in accordance with the application of the bass component. Done Therefore, when the air bag is inflated to some extent, its internal pressure is increased in a wavy manner, and the treatment site of the seated person can be compressed in a wavy manner via the air bag. Note that the present invention can be practiced by omitting the filter tank 75 in the above configuration. In this case, the pulsation of the air compressor 35 effectively spreads to the air bag, so that the wavy compression is used more effectively. You can massage in addition to the person.

In addition, in the above-mentioned massage, the pressure of the supplied air bladder is detected by the pressure sensor 36, and the detection signal is transmitted to the control device 31 to which the air bag is supplied.
It is always determined whether or not the predetermined pressure has been reached. Therefore, when the air compressor 35 is driven by using the bass component as a drive signal and the air supply to the air bag is performed irregularly, the control is performed immediately when the pressure sensor 36 detects the predetermined pressure. The rotary valve 37 is driven by the device 31 and this valve 37
The air in the air bag reaching the predetermined pressure is exhausted through the exhaust port. Therefore, although the input rate of the music signal used as the drive signal is irregular, that is, the expression of the bass component is irregular, the inflation pressure of the air bag to be supplied can be kept constant, and accordingly, the inflation pressure can be kept constant. Applying the compression force to the user can massage. In addition, since the pressing force can be kept constant as described above, even if the expression rate of the bass component is extremely high, it is possible to prevent the air bag from being pressed excessively.

It should be noted that as described above, the air compressor 3
A rotary valve 35 disposed in the middle of an air supply path from the air bag 5 to the air bag so as to exhaust compressed air supplied from the air compressor 35 to the rotary valve 35;
Alternatively, a dedicated exhaust valve for exhausting the compressed air is provided in the middle of the air supply path, and the compressed air is exhausted therefrom, and the compressed air is exhausted from the middle of the air supply path. If this is selected, the massage with the air bag is stopped, and the vibration massage using only the vibration of the air compressor 35 can be performed. In addition,
In this case, the use of the rotary valve 35 as in the former case does not require a dedicated exhaust valve, so that the configuration can be realized simply and inexpensively.

In the diaphragm type air compressor 35 for supplying air to the air bag, the pressure in the pump chamber 62 facing the diaphragm 51 increases with the increase in the internal pressure of the supplied air bag. The movement of the diaphragm 51 is suppressed, and the vibration generated by the compressor 35 is weakened. However, the massage machine 1 having the above-described configuration includes the pressure sensor 36 that detects the internal pressure of the air bag that is being supplied.
The gain of 2 is increased. Therefore, the vibrator 59 of the air compressor 35 can be reciprocated at a predetermined stroke, and the reduction of the vibration generated by the compressor 35 can be suppressed, so that the performance of the vibration massage by the air compressor 35 can be prevented from lowering.

In addition, the massage machine 1 having the above-described structure switches the switch 33 of the massage system 8 in accordance with the operation of the remote controller 6 to drive the electromagnetic drive mechanism 52 by the bass component and to reduce the electromagnetic force by the commercial power supply frequency. Either the driving of the expression driving mechanism 52 can be selected. Then, in the case of driving with the commercial power supply frequency, the air bag expands to a predetermined pressure in a predetermined time, and the vibration pattern becomes constant. Therefore, it is possible to selectively use the massage performed by the air bag and the vibration massage that are performed simultaneously according to the user's preference. In addition, since the switch 24 of the audio system 7 can be opened and closed according to the operation of the remote controller 6, if the switch 24 is turned off as desired, the above-described massage is performed with the music playback on the speaker 23 stopped. Can be.

In the massage machine 1 having the above-described structure, the air compressor 35, which is a vibration source, is disposed on the seat portion 12 to perform a vibration massage on the lower body far from the chest of the user, so that the feeling of use is good.

The present invention is embodied in the form described above and has the following effects.

According to the first and third aspects of the present invention, as the diaphragm type air compressor of the air supply / exhaust device performs the pump operation, the massage by inflation and contraction of the air bag attached to the massage machine main body is performed. Vibration massage to vibrate the base of the main body can be performed at the same time.Moreover, since the same air supply / exhaust device is shared by the air supply source to the air bag and the vibration source of the base, both massages can be performed with a simple configuration. realizable.

According to the second and third aspects of the present invention, as the diaphragm type air compressor of the air supply / exhaust device performs the pump operation in synchronism with the music signal, the air bag attached to the massage machine body is inflated. Massage by contraction and vibration massage performed by vibrating the base of the main body can be performed simultaneously, and the same air supply / exhaust device is shared by the air supply source to the air bag and the vibration source of the base. The two massages can be realized with a simple configuration.

According to the fourth aspect of the present invention, the driving signal for driving the electromagnetic driving mechanism can be selected from either the commercial power frequency or the music signal. Massage and massage can be performed simultaneously.

According to the fifth aspect of the present invention, it goes without saying that the diaphragm type air compressor is operated by applying the commercial power frequency, but the music signal is applied when the diaphragm type air compressor is operated by applying the music signal. Despite the irregular input rate, the inflation pressure of the air bag can be made constant based on the detection of the pressure of the air bag by the pressure sensor, and a constant pressing force can be exerted on the user to perform massage.

According to the sixth aspect of the present invention, regardless of the degree of inflation of the supplied air bag according to the input rate of the music signal supplied to the air compressor, the supplied air bag is compared. It is no longer necessary to maintain a halfway inflated state for a long period of time, and it is possible to massage the inflated and deflated airbags with a lip.

According to the seventh aspect of the present invention, the vibration generated by the diaphragm type air compressor decreases as the internal pressure of the air bag increases, by increasing the gain of the filter amplifier in accordance with the increase of the internal pressure of the air bag. It is possible to suppress the reduction of the vibration massage performance due to the air compressor.

According to the invention of claim 8, the air bag can be supplied according to the input rate of the music signal supplied to the air compressor within the time set by the timer. By giving a change according to the rate, it is possible to prevent massage familiarity.
