Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine which is capable of giving a comfortable massage without getting tired by adding fluctuation to the massage force.

[0002]

2. Description of the Related Art Conventionally, there is a massage machine which has a massage unit provided with massaging balls and which can be selectively or appropriately combined from a plurality of massage modes. Among these massage machines, , There is a massage machine that changes the operation speed of the massaging balls to give a comfortable massage for the user called fluctuation.

For example, the one disclosed in Japanese Patent No. 3093770 discloses a speed setting means for setting the operating speed of each kneading ball, a speed varying means for shifting the operation speed of all the kneading balls, and a kneading ball. It is equipped with a speed changing means for causing a 1 / f fluctuation speed change in the above operation and a control means for operating the kneading balls at a speed based on these means.

In such a massage machine, the control means has a speed determined by the sum of the speed increase / decrease value parameter set by the speed setting means for each operation and the reference speed parameter changed by the speed changing means. The kneading balls are operated based on the parameters, and the kneading balls are made based on the speed parameter determined by the sum of the speed increase / decrease value parameter based on the 1 / f fluctuation and the reference speed parameter changed by the speed changing means. The operation is performed at a speed change of 1 / f fluctuation.

With such a structure, it is possible to easily adjust each operation speed to a desired one as a whole, and to provide a speed changing means for causing a speed change of 1 / f fluctuation in the operation of the massaging balls. Because
It is possible to make the massage balls perform 1 / f fluctuations that are comfortable for a person and that have movement speed changes similar to the treatment operation by a professional masseuse.

[0006]

However, in the above conventional massage machine, when the fluctuation is applied to the massaging operation, the fluctuation is given by changing the rotation speed of the motor.

However, in some cases, such as a massage of kneading or a rolling massage, even if the rotation speed of the motor is changed, it may be difficult to feel the fluctuation.

In other words, this is a case in which the motor does not directly affect the pressing force applied to the body, but the rotation speed of the motor is changed to cause fluctuations. It is difficult to actually experience the fluctuations, and it was the current situation that there was not much difference in the feelings whether or not the rotation speed was changed.

That is, the change in the fluctuation speed of the massage machine must be such that the change in the number of revolutions is directly related to the strength of the pressing force on the body, as in the case of a motor that operates a hitting function or a motor that operates a vibration function. It is difficult to experience the fluctuations.

Therefore, there is a problem that the conventional technique cannot provide natural comfort due to fluctuations with massage functions other than the hitting massage and the vibration massage.

An object of the present invention is to solve the above-mentioned problems and to provide a massage machine which allows the user to experience the comfort of fluctuations when performing any massage function.

[0012]

The speed was continuously changed so that the pressing force fluctuates sensationally.

Further, in the present invention according to claim 4, in a massage machine in which a motor for exerting the function of advancing and retracting the massaging balls and a motor other than the motor are driven, and massage can be executed by a combined movement, the massaging position of the massaging balls. Was continuously changed to give fluctuation to the pressing force.

Further, in the present invention as set forth in claim 5, the massage machine is a chair type massage machine including a seat body and a reclining backrest.
The reclining angle can be changed continuously.

Further, in the present invention as set forth in claim 6, in a massage machine in which an air cell communicating with an air pump is provided, and air massage can be performed by supplying and discharging air by the air pump, a vibration function is provided near the air cell. The vibrator is provided so that the rotation speed of the motor of the vibrator can be varied during the air massage.

Further, in the present invention according to claim 7, the massage balls for massage are driven by a plurality of motors to perform massage in a hitting mode, a kneading mode, a rolling mode, a vibration mode, or a combined mode of these combined modes. In the massage machine that was made possible,
When performing a massage mode other than hitting mode or vibration mode when performing massage in each mode, either a motor for executing at least hitting mode or vibration mode, or an advancing / retreating motor that moves the massaging balls back and forth. One of them is driven at the same time, and the rotation speed or the number of rotations of the motor is continuously changed so that the pressing force fluctuates sensationally.

[0019]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, a plurality of motors including at least one of a motor that exerts a hitting function, a motor that exerts a vibration function, and a motor that exerts an advance / retreat function are driven to perform massage. In the enabled massage machine, when the massage is executed, the rotational speed or the rotational speed of the motor that operates the hitting function, the vibration function, or the advancing / retreating function is continuously changed so that the pressing force fluctuates sensationally. It is a thing.

That is, in the present embodiment, the massager is configured such that a massage body such as a massaging ball is directly contacted with the body of the user to apply a pressing force. In this case, the massaging user The user cannot experience the fluctuation unless the motor that directly affects the strength of the pressing force on the body is caused to fluctuate. As a motor for that purpose, select a motor that exerts a striking function, a vibration function, or a reciprocating function, and continuously change the rotation speed or the number of rotations of these motors so that the pressing force fluctuates sensationally. There is something.

Further, in the massage machine according to the present embodiment, the massage balls for massage are driven by a plurality of motors to perform massage in a hitting mode, a kneading mode, a rolling mode, a vibration mode, or a combined mode of these combined modes. When performing massage in each mode, when performing a massage mode other than hitting mode or vibration mode, at least a motor for executing hitting mode or vibration mode, or a motor for moving the kneading balls forward and backward. Any one of the above is simultaneously driven to continuously change the rotation speed or the number of rotations of the motor so that the pressing force fluctuates sensationally.

Therefore, it is possible to provide a high-performance massage machine which can surely give the user a pleasant feeling of fluctuations regardless of which massage mode is used.

Further, when the massage mode using the motor that does not directly relate to the strength of the pressing force of the massaging balls to the user's body is executed, even if the rotation speed of the motor is fluctuated, the fluctuation cannot be felt. However, in the present embodiment, any one of the above-mentioned motors, which are directly related to the strength of the pressing force of the massaging balls to the user's body, is simultaneously driven, so that the rotation speed of the motor is fluctuated. The user can experience the fluctuation, and a comfortable massage can be achieved in any massage mode to refresh the mind and body.

In order to chaotically fluctuate the rotation speed of the motor, for example, the motor rotation may be controlled by using a well-known mathematical expression for generating 1 / f fluctuation. It is also possible to generate a random number and use the 1 / f filter. Further, it may be a table expression in which a chaotic sequence is stored in the table.

In one embodiment, a motor for exerting a hitting function and a motor other than that are driven so that massage can be executed by a combined motion, and the rotation speed of the motor for exerting a hitting function is continuously changed. Thus, the pressing force can be perceived to fluctuate.

Further, as another embodiment, a motor for exerting a vibration function and a motor other than that are driven so that massage can be executed by a combined motion, and the rotation speed of the motor for exerting a vibration function is continuously changed. To
The pressing force can be perceived to fluctuate.

Furthermore, as another embodiment, a motor for exerting a function of advancing and retracting a massaging ball and a motor other than that are driven so that massage can be performed by a combined motion, and the advancing and retracting position of the massaging ball is continuously changed. It is possible to make the pressing force fluctuate. The kneading ball advancing / retreating motor can be used as a motor for continuously changing the advancing / retreating position of the kneading balls.

Further, it is preferable that the massage machine is of a chair type having a seat body and a reclining backrest.

By adopting the chair type, the user can receive a massage due to fluctuations in a relaxed state in a comfortable posture, so that a more comfortable massage can be received.

Further, the reclining angle can be made to continuously fluctuate, and the fluctuation of the reclining angle can also give fluctuation to the pressing force of the massaging balls on the user's body.

In this case, the rotation speed of the reclining motor for reclining the backrest is fluctuated, and the reclining angle is continuously fluctuated, so that the way the user's weight is applied to the massaging balls is changed. , As a result, it becomes equal to the change of the pressing force due to the advance and retreat of the massaging balls, which is directly related to the massage force. Therefore, the reclining motor can be regarded as a motor that operates the massaging ball advancing / retreating function, and the fluctuation of the rotation speed of the reclining motor causes fluctuations in the massage force, resulting in a comfortable fluctuation. It is possible to get a massage.

Moreover, depending on the control, the reclining motor is drive-controlled so that the forward rotation and the reverse rotation are continuously and slowly performed, and the backrest is gently moved up and down to determine whether the seat is sitting in a cradle or a rocking chair. Such comfort can be provided, and at this time, the rotation speed of the reclining motor is fluctuated, fluctuation is given to the vertical movement of the backrest, and the user feels a more natural sway, It is possible to further improve comfort.

Furthermore, as another embodiment, in a massage machine in which an air cell communicating with an air pump is provided and air massage can be performed by supplying and discharging air by the air pump, a vibration function is provided near the air cell. A vibrator may be provided so that the number of rotations of the motor of the vibrator can be varied during air massage.

When the massage machine is of a chair type, the air cell may be provided on the seat portion and / or the backrest, and instead of changing the rotation speed of the motor of the vibrator, the air pump supplies and discharges air. You may make it fluctuate directly. In this way, in the massage machine that has an air massage function in addition to the massage by kneading balls, there is fluctuation in the air massage by slowing down the rotation speed of the vibrator motor when performing air massage by expanding and contracting the air cell. By illusion as if to improve comfort, or by fluctuating the cycle of expansion and contraction of the air cell, it is possible to create fluctuations by air massage and have various massage forms, In addition, it becomes possible to make an excellent massage machine that can experience the bonito fluctuation.

[0035]

1 is a schematic explanatory view of a massage machine according to the present invention, FIG. 2 is a control block diagram of the massage machine, and FIG. 3 is an explanatory view showing a mechanism of fluctuation generation in the massage machine.

The massage machine 1 according to the present invention will be described as being applied to a chair type as shown in FIG. 1 through each of the following embodiments, but the present invention is not necessarily limited to the chair type, and for example, in a bed. It may be a so-called bed-type massage machine that supports the body of the user.

As shown in FIGS. 1 and 2, the massage machine 1 includes a seat main body 2 in which an air cell 2a, which is connected to an air pump P via an air solenoid valve, is housed and arranged so that the buttocks can be air massaged. The seat body 2 is connected to the seat body 2 so as to be reclining by a reclining motor RM and has a backrest 3 provided with an air cell 3a similar to the above. A heater H is arranged on the seat body 2 and the backrest 3 so that the massage effect can be enhanced by the heat. In this embodiment, when the heater H is used alone, it is automatically turned off within 60 minutes at maximum. Also, the timer of the heater H and the timer of each massage mode are independent,
The heater H is not turned off even when the massage is stopped or when the treatment operation is stopped.

Further, a vibrator V having a built-in vibe motor VM is disposed near the air cells 2a and 3a so that vibration massage can be performed.

In FIG. 1, M is the user, and 1a is a foot holding portion for holding the foot of the user M. The same air cell 1c as described above is accommodated in the foot holding portion 1a and the foot is held. I can do air massage. In addition, 1b is an armrest.

A massage unit 4 which is moved up and down along the height direction of the backrest 3 by a lifting motor 23 is arranged in the backrest 3.

As shown in FIGS. 1 and 2, the massaging ball drive unit 9 provided in the massage unit 4 strikes a pair of left and right massaging balls 5, 6 by swinging them in the front-back direction by a striking motor 57. The function and the kneading function performed by eccentrically rotating the kneading balls 5 and 6 by the kneading motor 67 can be executed, and the kneading ball drive unit 9 can move the backrest 3 of the backrest 3 by the advancing / retreating motor 38. It is configured to be able to move forward and backward toward the front side (the side in contact with the user), and it is possible to execute strong acupressure operation and complicated 3D rubbing operation.

Further, as shown in FIG. 1, the massage machine 1
Is equipped with a remote controller R capable of operating the power-on, power-off, and the entire operation of the massage machine 1. The remote controller R is provided with an operation section having various switch buttons and a display section made of liquid crystal, The seat 16 is wirelessly connected to a control unit 16 disposed below the seat body 2. Reference numeral 19 is a remote control storage provided on the front side of the armrest 1b. The remote controller R may be detachably attached to the upper surface of the armrest 1b.

With such a configuration, the massage machine 1 drives the above-mentioned plurality of motors from the automatic massage executed according to the predetermined program to the individual massage, and the hitting mode by the hitting function and the kneading function. Rubbing mode by, rolling mode by advancing and retracting function and lifting function, vibration mode by vibrating function,
Alternatively, various massage forms can be executed by a composite mode in which these are further combined.

The feature of the present invention in the massage machine 1 having the above-mentioned configuration is that the rotation speed or the rotation speed of the motor for applying the hitting function, the vibration function, or the advancing / retreating function is continuously changed when the massage is executed. The sensation is such that the pressing force fluctuates, that is, the rotation speed of the striking motor 57 is continuously changed so that the pressing force fluctuates sensationally. Another feature is that the rotational speeds of the VM and advancing / retreating motor 38 are continuously changed to give a sensation to fluctuations in the pressing force. Here, the concept of continuously changing the rotation speed of the advancing / retreating motor 38 includes a rotation speed of zero or a negative value, that is, a motor stop state or a reverse rotation, and during the advancing / retreating operation of the massaging ball drive unit 9. It is possible to give fluctuations to the reciprocating positions of the massaging balls 5 and 6 by stopping them or moving them back and forth slightly. For example, when fluctuation is given to the rotation speed of the hitting motor 57,
As shown in, the fluctuation in the hitting speed of the massaging balls 5 and 6 that hits the back of the user M will be given, and the strength of the hitting will continuously change accordingly, and the user The feeling of fluctuation in the hitting massage is felt. Here, as shown in FIG.
The fluctuation signal generating section A is electrically connected to the control section 16 for electrically controlling 7, VM and RM, and the fluctuation signal generating section A is connected to the remote controller R.

When a fluctuation signal is input from the fluctuation switch SY provided on the remote controller R, the intermittent chaos signal generator B generates an intermittent chaos signal sequence in real time by using a chaotic equation and follows the intermittent chaos signal sequence. The control unit 16 can add fluctuation to the rotation speed or the rotation speed of each motor 38, 57, VM, RM. As for the reclining motor RM, the fact that the reclining angle changes means that the massaging balls 5 and 6 in contact with the back move back and forth and exert a pressing force, which is almost the same. When fluctuations are given to the rotation speed of the motor RM, it can be said that the reclining angle of the backrest 3, that is, the vertical movement, fluctuates continuously, so that the pressing force on the back fluctuates.

As the chaos equation, a general logistic map or tent map can be used, and as disclosed in Japanese Patent Laid-Open No. 6-89106, a formula for generating 1 / f fluctuation is used. It can also be used. Alternatively, for example, in the fluctuation generation unit B ′ stored in a memory or the like, the random number from the random number generation unit B2 is used for the 1 / f fluctuation filter B1 to generate an intermittent chaos signal having different fluctuation characteristics, and this signal is generated. According to
The control unit 16 may add fluctuation to the rotation speeds of the motors 38, 57, VM, RM. In this case, dedicated hardware or program is required. Furthermore, the chaotic sequence may be stored in the table B ″, and the chaotic sequence may be extracted from the chaotic sequence to add fluctuation to the rotational speeds of the motors 38, 57, VM, RM. In this case, the storage capacity of the table B ″ is limited, and the same fluctuation pattern is repeated.

As described above, in the present embodiment, the rotation speeds of the motors directly hitting the massaging balls 5 and 6 against the user's body, that is, the hitting motor 57 and the reclining motor RM, are changed. Shaking it like chaos,
For the vibe motor VM, the rotational speed is chaotically fluctuated, and for the forward / backward motor 38, the massage force is fluctuated by stopping the motor or fluctuating it by continuously changing forward / reverse rotation. I am trying.

Therefore, as will be described later, in all types of massage modes, the motors 57, VM, 3 which directly contribute to the strength of the pressing force of the massaging balls 5, 6 on the user's body.
By controlling 8, RM, it is possible to give fluctuations to the massage power, to make the user M feel the fluctuations, and to provide a comfortable massage.

When performing a massage mode using a motor that does not directly relate to the strength of the pressing force on the user's body, such as the lifting motor 23 or the rubbing motor 67, that is, when performing a rolling massage or a rubbing massage. , For example, the hitting motor 57 or the vibe motor
The VM can also be driven at the same time to change the rotation speed and the rotation speed of the motor 57 (VM) to change the pressing force, so that the user can experience a sufficient fluctuation in the massage force. Feels as if the rolling or kneading massage you have selected is fluctuating, and you can feel the comfort you have never seen before.

Here, a case where the fluctuation massage is actually performed will be described.

(1) When the automatic course is selected For example, when the automatic course is selected and massage is performed, the fluctuation switch SY provided on the remote controller R may be turned on.

That is, in the massage mode programmed in the automatic massage course, when performing the tapping massage or the acupressure massage, the control unit 16 controls the tapping motor 5
7. The advance / retreat motor 38 is controlled based on the intermittent chaos signal from the fluctuation signal generation unit A to fluctuate the rotation speed of the motor, and fluctuations that give a comfortable feeling to humans with respect to the massage force. Add chaos. Therefore, unlike the automatic massage in which each mode is simply combined, the user M can experience a comfortable massage due to fluctuations close to changes in the natural world when tapping or acupressure, and more refreshing the mind and body. Done effectively.

In addition, when, for example, a massage for kneading or a rolling massage is performed during the automatic course, for example, by controlling the motor 38 for advancing and retracting and adding and driving fluctuations to the advancing and retracting positions of the kneading balls 5, 6. Despite the fact that there is no fluctuation in actual rubbing or rolling, the advancing / retreating position of the rubbing balls 5 and 6 fluctuates due to the control of the advancing / retreating motor 38, which is directly related to the pressing force on the body, and as a result, the kneading is physically felt. You can feel as if the massage by rolling is fluctuating and you can get a comfortable massage feeling. In addition, the massaging balls 5, 6
2, the body shape data of the user M acquired in advance is stored in the memory m, and the memory m is called and referred to from the detected value of the amount of advance / retreat by the rotary encoder 92 described later. The advancing / retreating positions of the kneading balls 5, 6 are determined based on the obtained position information.

For the detection of body shape data, the body shape detecting step of advancing the kneading balls 5, 6 to the user M side is repeated for each ascending operation consisting of a predetermined unit movement amount, and kneading balls 5, 6 are carried out. Is coordinated with the position of contact with the portion to be treated (back of the user M) and the coordinates are traced to detect the body shape line.

(2) When individual function is selected Even when the individual function is selected, the user M can obtain a feeling of fluctuation in massage in each mode by turning on the fluctuation switch SY provided on the remote controller R. .

The mechanism for imparting a feeling of fluctuation to the user M is as described above, and when performing a tapping massage or acupressure massage, the control unit 16 controls the tapping motor 57 and the advancing / retreating motor 38 to The rotation speed is controlled based on the intermittent chaos signal from the fluctuation signal generator A.

When the massage of kneading or rolling massage is selected, the motor 67 for kneading and the motor 23 for raising and lowering are controlled by the normal constant rotation.
When SY is on, in addition to the motors 67 and 23, the vibrator VM VM or the advancing / retreating motor 38 is driven, and fluctuation is added to the motor so that there is no fluctuation in the actual massage or rolling massage. Instead, fluctuations in the rotation speed of the vibe motor VM and the advancing / retreating motor 38, which are directly related to the pressing force on the body, make the user feel that the overall massage force fluctuates, and the feeling of massaging and rolling is fluctuating. It is possible to feel as if you are out and to get a comfortable massage feeling.

(First Embodiment) A first embodiment will be described below with reference to FIGS. 5 and 6 in which fluctuations are given to the rotational speed of the beating motor 57 or the vibe motor VM. FIG. 5 is an explanatory view showing the mechanism of fluctuation generation according to the first embodiment, and FIG. 6 is a kneading ball when the rotation speed of the vibe motor VM is fluctuated when kneading a massage.

And during the massage mode in which the lifting motor 23 is operating,
When a fluctuation signal is input from the fluctuation switch SY provided on the remote controller R, the fluctuation signal generation unit A generates an intermittent chaos signal sequence in real time using a chaotic equation, and the control unit follows the intermittent chaos signal sequence. 16
Adds fluctuation to the rotation speed of the vibe motor VM, for example.

In this case, the kneading balls 5 and 6 perform the kneading massage operation. However, since the fluctuation is added to the rotation speed of the vibe motor VM, as shown in FIG. The vibration of the vibrator V having a built-in vibration causes fluctuation, and the user M feels as if the massage is fluctuating, and the user feels a comfortable kneading massage with a fluctuation that has never been seen before.

In addition, while the massage of rubbing is being performed, fluctuations are given to the number of rotations of the vibe motor VM.
Drive the beating motor 57 instead of the vibe motor VM,
Further, fluctuation may be added to the rotation speed of the hitting motor 57. Furthermore, while driving the elevating motor 23 to perform the rolling massage, the vibe motor VM is driven to give fluctuations to the rotation speed of the vibe motor VM, or the striking motor 57 is driven. Moreover, fluctuations can be added to the rotation speed of the hitting motor 57.

As described above, when the beating motor 57 or the vibe motor VM for exerting the beating function or the vibration function and the other motors are driven to execute the massage, the rotation speed of the beating motor 57 is changed. By continuously changing or continuously changing the number of rotations of the vibration motor VM, it becomes possible for the user M to perceive the fluctuation in the pressing force.

Is.

As shown in FIG. 7, the fluctuation signal is input from the fluctuation switch SY provided on the remote controller R during the rolling massage by driving the advancing / retreating motor 38 and the lifting / lowering motor 23, and the fluctuation is inputted. In the signal generator A, an intermittent chaos signal sequence is generated in real time using a chaotic equation, and the control unit 16 controls the rotation of the advancing / retreating motor 38 on / off in accordance with the intermittent chaos signal sequence. Fluctuation is added to the advancing / retreating position of 6 ,.

Then, as shown in FIG. 8, the forward and backward positions of the massaging balls 5 and 6 are continuously changed, and the pressing force fluctuates. As a result, the rolling massage fluctuates to the user M. You will be able to experience a comfortable rolling massage with a feeling of fluctuation that has never been seen before.

While the rolling massage is being performed here, the advancing / retreating motor 38 is controlled to change the advancing / retreating positions of the massaging balls 5 and 6 so as to impart fluctuation.
Even in the case of a kneading massage in which the kneading motor 67 is driven, when a fluctuation signal is input from the fluctuation switch SY, the advancing / retreating motor 38 is controlled to continuously move the advancing / retreating positions of the kneading balls 5 and 6 as described above. By changing it, it is possible to make it feel as if the massage massage is fluctuating. Further, as described above, the fluctuation can be experienced even if the rotation speed of the hitting motor 57 is fluctuated, but for example, when the hitting motor 57 is driven,
By controlling the advancing / retreating motor 38, as described above, the massaging balls 5, 6
It may be possible to give a feeling of fluctuation by continuously changing the advance / retreat position of.

As described above, when the massaging balls 38 are operated by driving the advancing / retreating motor 38 for exerting the advancing / retreating function of the massaging balls 5, 6 and the other motors, the advancing / retreating positions of the massaging balls 5, 6 are continuously changed. By changing to, it becomes possible for the user M to feel the fluctuation in the pressing force.
