DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type massage machine, and more particularly to a chair-type massage machine having a pressing force detecting means for detecting a pressing force of a roller to a massage site.

[0002]

2. Description of the Related Art Conventionally, as this kind of chair type massage machine, there is known a chair type massage machine which detects a shoulder position (part) of a user (person to be massaged) sitting on a chair of the massage machine. In other words, the position of the shoulder, the position of the back or the position of the waist of the human body are in a certain ratio relationship to each other, and if the position of the waist can be derived from the above ratio if the position of the shoulder can be recognized, the position of the shoulder is considered. Chair-type massage machines to be detected are known. In such a massage machine, the position of the shoulder is detected, and another massage site such as the waist is automatically shifted and determined according to the change in the position.

As another chair-type massage machine, there is known a massager in which a massaged part of a massaged person sitting on a chair of the massage machine is divided into three parts: an upper part, a middle part, and a lower part.

[0004]

However, in the former chair-type massage machine, the position of the shoulder can be accurately detected, but there are the following problems. That is, for example, even if the same massaged person has different waist styles (the position of the shoulders is higher when the user is deeply seated and the position of the shoulders is lower when the user is shallower), the position of the shoulders is different. . For this reason, each massage part is also detected differently, and there is a possibility that the massaged person may receive an unpleasant massage. Further, if an attempt is made to input the positional relationship between the shoulder and the waist, such as gender, age, or type of person, an input device, a storage device, and the like are required, leading to an increase in cost.

On the other hand, in the latter chair-type massage machine, since the massaged part of the massaged person is roughly divided into three parts and detected, the position detection of each part is inaccurate, and for the user, There was a problem of receiving an unpleasant massage.

The present invention has been made in view of the above circumstances, and there is no error in detecting a massaged part due to how to sit down, and there is no error in detecting a massaged part due to gender, age, and type of person. An object of the present invention is to provide a chair-type massage machine capable of obtaining an appropriate massage effect.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a chair on which a person to be massaged sits, a massage roller provided on a backrest of the chair so as to be vertically movable, and a massage part of the roller. And a control unit for controlling the pressing force of the roller based on the detection result of the pressing force detecting means, and further, the roller is moved along the massaged person sitting on the chair. Scan from the movable lower limit to the upper limit,
This is a chair-type massage machine including a part detecting means capable of detecting each massage part of the neck, shoulder, back and waist of a massaged person from a pressing force curve obtained thereby.

[0008] That is, the chair type massage machine of the present invention is provided with a specific part detecting means, which causes the roller to scan from the lower limit to the upper limit of the movable range along the massaged person sitting on the chair. The gist of the present invention is to detect massage parts of a neck, a shoulder, a back, and a waist of a massaged person from a pressing force curve obtained thereby. Then, an error of detection of the massage part due to the method of sitting on the waist and an error of detection of the massage part according to gender, age, person type and the like are eliminated, and an appropriate massage effect is obtained.

Here, the pressing force curve may be obtained by making the pressing force constant, or by making the angle of the roller arm for supporting the roller vertically movable.

[0010] More preferably, the detection of the massage part by the part detecting means is performed, for example, as follows before performing the massage. That is, when the massaged person sits down on the chair and leans on the backrest, the main switch is turned ON. Then, the part detection lamp in the display unit is turned on, and detection of the massage part is started. Confirm that the lamp is turned off and the detection is completed, and enter your preferred massage method. As described above, the massage part is detected as the initial operation of the massage, and the appropriate massage is performed according to the part. In addition,
Even if the massage method is input immediately after the main switch is turned on, it is also possible to set so that the region detection is always performed before the massage operation starts.

[0011] It is more preferable that the chair type massage machine is provided with an input storage means for inputting and storing a plurality of pieces of information detected by the site detecting means. In that case,
A person who has once performed region detection (a person to be massaged using this massage machine) registers the region with a symbol or the like on a display in the display operation unit. This person presses the call button at the next massage and checks his or her symbol on the display. Then, if the user inputs his / her detection information and then inputs the massage method, the massage can be performed without the detection operation.

The pressing force detecting means of this chair type massage machine preferably has a specific strain gauge. The strain gauge is provided on a roller arm that allows the roller to move up and down by a motor, and detects a pressing force of the roller on a massage site. Further, it is preferable to adopt a shape of a beam-type load cell widely used for a commercial small scale (1 kgf to 100 kgf) or the like for the roller arm. Roller pressing force of chair type massage machine is usually 0-50kgf
Therefore, if a beam type load cell is used, it is possible to control the pressing force at low cost and with high accuracy.

This chair type massage machine is provided with an input means capable of continuously changing a massage part or a massage area, and a variable range of which is automatically changed from the massage part obtained by the part detecting means. preferable. With this configuration, it is possible to continuously specify a region to be massaged (for example, a shoulder) or a region to be massaged (for example, from where to where on the shoulder) based on the detection result detected by the region detecting unit,
The specified range can be changed automatically. For example, a massage of the “shoulder” portion that matches the body shape of the person to be massaged can be designated simply by adjusting the display to an easy-to-understand display such as “shoulder”. And it becomes an easy-to-use device for a wide range of massaged persons.

It is preferable that the chair type massage machine is provided with input means for designating a massage site and inputting a massage area and a massage intensity at the designated site. With such a configuration, the massage area and the massage intensity can be input to obtain a massage pattern unique to the massaged person. For example, a “pain button” is provided, and a place where a massage treatment is desired is displayed on a display. Then, a massage area and a massage strength are input based on the display. If a massage of appropriate intensity is intensively performed on a part to be massage-treated specified by the "pain button", comfortable treatment can be performed.

In this chair type massage machine,
In some cases, it is desirable to arrange a plurality of transducers (vibration generating elements) in the back portion of a chair and activate the transducers to vibrate the body when sitting down on the chair and listening to music. In such a case, it is preferable to provide a control unit that controls so as to stop the operation of the transducer corresponding to a part that the user does not want to vibrate, such as the back side of the stomach, among the massage parts detected by the above-described part detection unit. preferable.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited by this.

FIG. 1 is a structural explanatory view of the inside of a chair type massage machine A viewed from the back. In FIG. 1, the rotation of a motor 1 located at a lowermost position inside a backrest portion of a chair in a chair type massage machine A is decelerated by a pulley and a belt 2 and transmitted to a screw shaft 3. The elevating unit 4 and the screw shaft 3 are fixed to the elevating unit 4, so that the screw members 5a
5b. The elevating unit 4 is mounted on guide rails on both sides of the chair by guide rollers 6a, 6b, 6c, and 6d. Then, the screw shaft 3 is moved up and down along the guide rail by the forward and reverse rotation of the screw shaft 3.

The lifting unit 4 reaches the upper limit switch 7a as it continues to ascend, and reaches the lower limit switch 7b as it continues to descend. The vertical position can be recognized by detecting a pulse from the vertical movement detecting magnet reed switch 8. Each time the screw shaft 3 makes one rotation,
A pulse is generated when a magnet 9 attached to the screw shaft 3 passes in front of the reed switch 8.

FIG. 2 is an explanatory view of the configuration of the roller driving mechanism disposed inside the elevating unit 4. Inside the lifting unit 4, the rotation of the motor 10 is controlled by a pulley 11, a belt 12,
The speed is increased by the pulley 13 and transmitted to the worm shaft 14.
The roller arm 1 is attached to the shaft 15 fixed to the lifting unit 4.
6 and the worm wheel 17 are screwed. The worm wheel 17 has a fan shape, and rotation from the worm shaft 14 is transmitted. At the upper end of the roller arm 16, a shaft 1
8, a pair of left and right massage rollers 19a and 19
b is attached.

When the worm wheel 17 rotates in one direction, the rollers 19a and 19b rotate obliquely upward (in a direction away from the massaged person) about the shaft 15.
When the worm wheel 17 rotates in the other direction, the rollers 19a and 19b rotate about the shaft 15 in a diagonally downward direction (a direction approaching the massaged person). The range of such movement is limited by the contact of the worm wheel 17 with the limit switches 20a and 20b. The angle of movement can be determined by obtaining the rotation pulse of the worm shaft 14 by the push / pull movement detection switch 21. Worm shaft 1
Each time the motor 4 rotates once, the magnet 22 attached to the worm shaft 14 passes in front of the switch 21 to generate a pulse.

The roller arm 16 adopts the shape of a beam-type load cell which is widely used in commercial compact and lightweight devices. That is, a beam-type load cell in which two circular holes are formed in a rectangular flat plate and the circular holes are connected by slits is employed. And the strain gauges R1 to R
4, the pressing force of the roller arm 16 is detected from the bridge circuit. FIG. 3 shows the bridge circuit.

Hereinafter, the electrical configuration will be described for each block with reference to FIG. The configuration can be roughly divided into a microcomputer section,
There are four blocks: a display operation unit, an upper / lower motor controller, and a pressing motor controller. Hereinafter, description will be given for each component of each block.

The microcomputer section is a brain section comprising the one-chip microcomputer 101 and peripheral circuits (not shown) such as a reset circuit, and performs all controls after the power is turned on. Interface processing with an input from a user (person to be massaged), a sequence of a massage operation, and the like are stored in an internal memory, and control is performed on peripheral input / output devices according to each scene.

Display Operation Unit The display operation unit 102 checks the operation section where the user inputs each command including the start and end of massage, and the operation status of the operation section to confirm the state of the massage machine. And a display unit. The operation unit has a changeover switch for switching the operation mode, a start / stop switch, and a means for setting a massage position, an area, and a strength. When these operations are performed, the one-chip microcomputer 101 returns display information according to the operations. The user inputs the next command while checking the display information.

Upper / lower motor control unit Upper / lower limit switch 7, upper / lower motor control circuit 10
4 and magnet reed switch 8 for up / down movement detection
Consists of The upper and lower limit switches 7 (7a and 7b) are respectively disposed at the upper limit and the lower limit of the vertical movable area of the lifting unit 4. These switches 7 have a function of preventing the vertical movement beyond the movable area and a function of resetting the vertical position when the power is turned on. That is, when the power is turned on, either the upper limit switch 7 or the lower limit switch 7 is searched, and when the switch 7 is turned on, the switch 7 is set to the vertical position 0.

The upper / lower motor control circuit 104 includes an arm 16
Is a circuit for driving a motor for moving the motor up and down. When an AC motor is used, a triac or thyristor is used in this circuit to rotate the motor forward or backward according to the output from the one-chip microcomputer 101 to move the arm 16 up and down.
The switch 8 is configured to generate a pulse for each constant movement amount when the arm moves up and down due to rotation of the upper and lower motors. Specifically, it is composed of a magnet attached to a shaft connected to the upper and lower motors and a magnet reed switch, and generates a pulse each time the shaft rotates. When the power is turned on, the current position in the up-down direction can always be grasped from the 0 position obtained as described above, the information on the upward or downward moving direction, and the pulse count of the switch 8.

Push motor control unit Push / pull limit switch 20, push / pull motor control circuit 10
7. Load sensors R1 to R4, push / pull movement detection switch 2
1, a zero-cross detection unit 110 and a load reference value generation circuit 111. Push-pull limit switch 20 (20a
Reference numeral 20b) is provided at the push-side limit and the pull-side limit in the movable region of the push-pull operation of the arm 16. These switches 20 serve to prevent the arm from moving out of the movable region and to reset the position information of the arm angle when the power is turned on. The push / pull motor control circuit 107 includes an arm 16
And a feedback circuit based on a comparison between a load (pressing force) applied to the arm 16 and a target value.

The load sensors R1 to R4 are attached to the arm 16, and convert a load (pressing force) applied to the arm 16 into an electric signal. This signal is transmitted to the one-chip microcomputer 101 and the push / pull motor control circuit 107. The one-chip microcomputer 101 detects the body part (massage part) of the user from the change of the signal,
It detects whether the target load has been reached or not. The push / pull motor control circuit 107 compares this signal with the signal from the load reference value generation circuit 111, and controls the motor so as to push or pull the arm 16 according to the difference.

The push / pull movement detection switch 21 generates a pulse for each constant movement amount when the angle of the arm 16 changes due to the rotation of the push / pull motor 10. Its configuration is the same as that of the above-mentioned vertical movement detection switch 8. Also, the arm 16
Is also grasped from the switch 21, the push-pull limit switch 20, and the information on the moving direction.

The zero-cross detector 110 is provided for the purpose of controlling the phase of the push / pull motor so that the angle of the arm 16 changes smoothly when the load on the arm 16 is near the target value. That is, the one-chip microcomputer 10
1 judges whether or not it is close to the target load based on input signals from the load sensors R1 to R4. If it is close, the ON / OFF signal is sent to the push / pull motor 10 at an arbitrary duty in synchronization with the timing of the zero cross input. When the duty is low, the movement speed of the push-pull motor 10 is slowed, so that the movement can be smoothed as a result.

The load reference value generation circuit 111 receives a signal corresponding to the operation mode or the strength specification from the one-chip microcomputer 101 and converts it into a signal level to be sent to the push / pull motor control circuit 107 as a target load of the push / pull motor 10.

Next, a method of detecting a massage site will be described with reference to the flowchart of FIG. Load sensors R1 to R
Reference numeral 4 is attached to the arm 16 (FIG. 2), and senses by detecting the amount of deformation of the arm 16 due to the load. In step 130 of FIG. 5, the microcomputer 101 outputs to the load control reference value generation circuit 111 so that the arm 16 generates a fixed amount of distortion. In step 131, the arm 16 is returned to the lowermost position prior to sensing the load change from bottom to top. In step 132, the pushing motor 10 is stopped at an angle to obtain the distortion amount specified in step 130, and the up / down movement motor 1 starts rotating in the ascending direction.

In step 133, the detection by the upper limit switch 7a is performed, and it is determined whether or not the load sensing from the bottom to the top is completed. When completed, the part detection routine is terminated. In step 134, a pulse input from the up / down movement detection switch 8 is monitored. If a pulse is input, the process proceeds to step 135, and if not, the process returns to step 133 to check the upper limit switch 7a. In step 135, based on the pulse in step 134, the position counter indicating the position in the vertical direction is incremented, and the inputs from the load sensors R1 to R4 are taken in.

FIG. 6 shows an example of the load sensor input and the vertical position count value taken in at this time. The data of the subject 1 represented by a solid line is the most typical example, and has peaks on the back and the head and a depression on the neck. The person to be measured 2 represented by a broken line also draws a similar curve, but the person to be measured 3 indicated by a dashed line has peaks at the hip and the back, and the peak at the head does not appear. Unlike other data, there is a peak at the hip because it is deeply seated, and there is no peak at the head because the head is above the vertically movable area of the arm 16.

As is apparent from these data, the position detection of each part is obtained from the peaks and valleys of the curve drawn by the inputs of the load sensors R1 to R4. In step 135, the input values of the load sensors R1 to R4 are compared each time to obtain the positions of these peaks and valleys. When a peak or a valley is found, it is stored in the internal memory of the microcomputer 101, and the process returns to step 133 again. The mountain obtained in this way,
The detection of the massage site from the valley position count value is performed as follows.

If two peaks are obtained at a low position, it is determined that the user is sitting deep, the valley between them is regarded as the waist position, and the next peak is regarded as the back position. If there is only one peak at a low position, the sitting height of the user is estimated from the interval between the peak and the next valley. Then, the distance between the back and the waist is calculated from the sitting height to determine the waist position. The next mountain is the back position and the valley is the neck position. From these, it is possible to estimate the sitting height and calculate the shoulder position located therebetween. Further, the next mountain is the head, but is not particularly used in this embodiment.

As described above, by utilizing the pressing force curve (load curve) obtained when the rollers 19a and 19b are scanned along the human body from the lower limit to the upper limit, the position of the neck, shoulder, back, and waist can be determined. , Regardless of gender, age, or race. Thereby, appropriate massage according to each position is performed, and more effective treatment can be performed. In this example, the pressing force curve was obtained while keeping the angle of the roller arm 16 constant.
Instead, the pressing force is kept constant and the roller arm 16
May be changed.

The roller arm 16 is formed with two circular holes to form four notches as shown in FIG. 2 in order to form a strain-generating body of a beam type load cell, and a strain gauge R1 is provided in each notch.
To R4. When the rollers 19a and 19b contact the massaged person and receive a reaction force F of the pressing force, tension acts on the strain gauges R1 and R4, and compressive force acts on the strain gauges R2 and R3. These four strain gauges R1 to R4
Is connected to a bridge circuit as shown in FIG. 3, and a pressing force F is obtained from an output voltage e2 when a constant voltage is applied to e1. e
2 is amplified by an amplifier, this is input to the microcomputer,
The control of the pressing force is performed. Here, the material of the arm 16 is an aluminum alloy A2024, and the processing method is forming.

As described above, when the roller arm 16 is a beam-type load cell using the strain gauges R1 to R4, the accuracy of the detected load is good (non-linearity, hysteresis, repeatability), so that fine control can be performed. Treatment software spreads.
Further, since the beam-type load cell has a so-called Roberval mechanism, a load deviation due to an unbalanced load is small. That is, when the human body comes into contact with the rollers 19a and 19b, even if the contact point between the human body and the rollers 19a and 19b moves, the influence is not exerted, and a constant load detection is always performed, so that more appropriate control can be performed. Further, the strain-generating body of the beam-type load cell is used for the roller arm 16, and as the load detecting means, it is only necessary to add the strain gauges R1 to R4 and a sensor circuit.

The conventional chair type massage machine is provided with an input device as shown in FIG. 7 or an input device as shown in FIG. That is, the former can input high / medium / low height adjustment and vertical adjustment, and is used for automatic driving and whole body massage. The latter allows the user to input upper / middle / lower up / down adjustment and 0-7 shoulder position adjustment, and is used for partial massage. For this reason, when the user wants to massage the shoulder, it is necessary to adjust until the massage roller comes to the shoulder position while actually operating the massage machine, and the adjustment takes time.

In the chair type massage machine A according to the embodiment of the present invention, as shown in FIGS. 9 and 10, the massage part and the massage area can be continuously changed, and the variable range is obtained by the part detecting means. It has input means that is automatically changed from the massage site. Less than,
explain in detail.

Using the detection result of the massage site obtained as described above, the variable range of the massage site and the massage area is automatically changed as follows. That is, FIG. 11 is a flowchart of the automatic change process. In step 136, the volume value input by the input means as shown in FIG. 9 is fetched via A / D conversion. Based on the value at this time, it is determined where the position of the slide volume knob is. Then, it is divided into three groups: an area below the back, an area from the back to the shoulder, and an area above the shoulder. Steps 137-13
9 is a calculation formula after the division.

In step 137, the minimum unit by inputting a volume below the back is determined by dividing the distance between the back and the waist detected in the first term by the resolution of the volume in that range. Then, by multiplying the minimum unit by how much the volume position is deviated from the waist setting position in the second term, the detected waist position is corrected. The same applies to steps 138 and 139, and the process is completed.

According to such a method, FIGS.
When using an input device such as 0, the user is not up, down or relative to the current position of the roller arm 16,
The massage part can be adjusted using the indication of the part such as "waist", "back", "shoulder", and "neck" as a guide. Also,
Even when the user sits on the massage machine shallowly, since the waist position is calculated, the position can be adjusted according to the body shape of the user even if the posture when sitting is poor.

The chair-type massage machine A further includes input means for designating a massage site and inputting a massage area and a massage intensity to the designated site. This input means is, as shown in FIG.
1. A slide knob 32 for specifying a pain position, a slide knob 33 for specifying a massage area, and a slide knob 34 for specifying a massage intensity are provided.

FIG. 12 illustrates the display unit 30 related to the input means in the display / operation unit. When the main switch 35 of the massage machine is turned on, the position detection lamp 36 is turned on, and detection of the massage site is started. If the massaged person feels pain in the body during this operation, the pain button 31 is pressed. The signal at this time is input to the microcomputer and stores the count number counted by the vertical movement detecting magnet reed switch 8.

Each part of the body is estimated from the pressing force curve obtained as shown in FIG. 6, and a human figure 37 of the display 30 is formed. Further, the pain location 38 is estimated from the count value of the pain button 31 and is displayed on the human figure 37. Next, the massaged person slides the knob 32 to set the pain location 38, and slides the knob 33 and the knob 34 to input the desired massage area and massage strength, respectively.

FIG. 13 shows three pain spots 38a and 38b.
38c. In this case, the massaged person first sets the knob 32 to the lowermost pain location 38a,
The massage area (width) X1 and the massage strength Y1 are input. Similarly, the other two pain locations 38b and 38c
, X2, Y2, X3, and Y3 are input. The load pattern 39 obtained in this manner is unique to the massaged person. Then, it is possible to set an effective massage at a desired treatment site faster than in the conventional case. Thereby, a great effect is exhibited when there are a plurality of treatment desired locations. The pain button 31 can be used not only during the operation of detecting the massage part but also during the normal massage operation.

[0049]

Since the chair type massage machine of the present invention is constructed as described above, errors in detecting a massaged part due to how to sit down and errors in detecting a massaged part according to gender, age, and type of person. And a proper massage effect can be obtained.
