[0028]
As shown in FIGS. 1 to 6, the massage device A is easily provided by storing and arranging a geared motor M or other parts as a driving means in a small case body 1 having a pair of handle portions 10 and 10. The case main body 1 is composed of a halved upper case 11 and a lower case 12 in which arch-shaped handle constituting portions 10a and 10a are formed on the left and right side portions.
[0029]
A treatment part B is provided on the surface of the upper case 11, and the treatment part B is provided with two treatment bodies 2, 2 which are rubbed balls in a left-right parallel state. And the recessed part 13 and 13 are formed in the upper and lower sides of the said treatment part B between the left and right handle parts 10 and 10, respectively.
[0030]
7 shows the inner surface of the upper case 11, and as shown in the figure, two substrates 3a and 3b are arranged between the left and right handle components 10a and 10a and the treatment part B is sandwiched between them. Both substrates 3a and 3b are connected by a connecting cable 4.
[0031]
On one substrate 3b, a push button type power switch 5 and a slide type strength change switch 6 are arranged. In the present embodiment, the geared motor M is driven with a voltage of 12V when strong and 10V when weak.
[0032]
On the other hand, the lower case 12 is provided with a plurality of joining bosses 14 for connecting the upper case 11 on its inner surface (FIG. 5), and among them, a boss 14a that also serves to fix the treatment body 2 is provided. The bosses 14a are provided so as to form a substantially equilateral triangle, and the bosses 14a are formed taller than the joining bosses 14 (FIG. 6), and are treated when a driver is inserted or viewed from the outside. 2 can be easily identified.
[0033]
Further, as shown in FIGS. 2 and 3, the lower case 12 is provided with a power switch operating piece 5a and a strength changeover switch operating piece 6a at a rising portion which is abutted with the upper case 11 to form a side wall portion. Yes. Reference numerals 50 and 60 denote operation piece recesses for providing both operation pieces 5a and 6a.
[0034]
In addition, the AC adapter connecting recess 15 is formed in a large curved shape at a position where the recesses 50 and 60 are opposed to each other, and a belt-like shape is provided between the recess 15 and the operation piece recesses 50 and 60. The anti-slip bodies 16 and 16 are arranged in a facing state at a predetermined interval. In FIG. 2, J is an AC adapter, J1 is the same cord, J2 is the same plug, 15a is a plug receiver provided at the bottom of the AC adapter connecting recess 15, and 17 is a case connecting screw.
[0035]
Next, the treatment body 2 will be described.
[0036]
As shown in FIGS. 1 and 3 to 6, the two treatment bodies 2 are the same as the acupressure rotator 20 connected to each reduction gear shaft M <b> 1 of an independent geared motor M as a drive source. A cover 21 that covers the rotating body 20 and a fixing ring 22 of the cover 21 are configured. Since each treatment body 2 is driven by an independent geared motor M, the case body 1 can be compactly laid out.
[0037]
Furthermore, since the geared motor M is made independent, even if a force is applied to one, the other is not affected, so that the usability is good. This is because, for example, in a structure in which one motor is used and two treatment bodies are driven via a worm gear or the like, if too much force is applied to one, both rotation speeds become slow. In FIG. 6, E is a reduction gear of the geared motor M.
[0038]
The acupressure rotator 20 is formed of a strong and slippery polyacetal resin. As shown in FIGS. 6, 8, and 9, the acupressure rotator 20 is formed on a horizontally rotating pedestal 23 having a substantially triangular shape in plan view. Each ball 24 is attached and arranged on the treatment body receiving portion 12a shown in FIGS. 12b is a partition wall formed so as to surround the treatment body receiving portion 12a, and 12c is a cover placement portion.
[0039]
Each ball 24 is inserted into three ball receiving portions 25 formed on the pedestal portion 23 so that at least the top portion is exposed and is rotatable and does not fall off.
[0040]
A D-cut reduction gear shaft M1 is inserted through a connecting boss portion 26 formed at the center of the pedestal portion 23 (FIG. 5) and fixed with a general screw 27 and a nut 28. By adopting such a configuration, the assembly process can be simplified, and the manufacturing cost can be reduced.
[0041]
Further, the ball receiving portion 25 is cut obliquely downward from the upper end side to the outer side so that the affected portion smoothly contacts the ball 24 even from an oblique direction to form a cut end portion 25a.
[0042]
Further, the three balls 24 are attached at different heights of height, middle, and low, and are arranged close to the center of the pedestal 23 in descending order (FIG. 8). That is, the distance between the ball receiving portion 25 and the center of the pedestal portion 23 is different, the ball receiving portion 25 at the highest position is the closest, and the ball receiving portion 25 at the lower position is the most separated. I am letting.
[0043]
With the above configuration, when the left and right acupressure rotators 20 are rotated, the pressing cycle for pushing up the affected area and the pressing release cycle for releasing the pressing force are repeated, and the difference in pressing force is large and strong. An acupressure effect can be obtained, and any one of the balls 24 follows the concave portions of the body, such as the limbs, the neck, and the back, and the acupressure can be surely performed.
[0044]
Furthermore, since the distance between the center of the pedestal 23 and each ball 24 is different, the rotation of the acupressure rotator 20 causes each ball 24 to rotate on concentric circles having different radii, thereby increasing the acupressure radius. The acupressure area can be increased.
[0045]
The acupressure rotator 20 is covered with a cover 21 as shown in FIG. 5, and the cover 21 is double-tensioned as shown in FIG. The outer fabric 21 'is a strong and soft fabric, knitted with 88% nylon and 12% polyutane. The inner fabric 21' 'is slippery and easily rubs against the ball 24. The fabric is not torn and is knitted by mixing 80% polyester and 20% polyurethane.
[0046]
As shown in FIG. 10, the cover 21 is stitched around the periphery of the outer / inner cloth 21 ', 21' 'cut into a circle to form a fastener insertion passage 21a, and the fastener 21b is inserted into the insertion passage 21a. Is formed into a dome shape as shown in FIG. 5 and FIG.
[0047]
Such a cover 21 ensures smooth rotation of the acupressure rotator 20 and prevents a user from accidentally pushing a finger or the like into the acupressure rotator 20 to be injured.
[0048]
Further, as shown in FIGS. 5 and 6, the cover 21 is sandwiched between the upper case 11 by a fixing ring 22.
[0049]
As shown in FIGS. 13 and 14, the fixing ring 22 is formed in a cap shape having a hole 22a in the center for exposing the rotating body 20 for acupressure covered with the cover 21, and the peripheral wall 22b is formed in the upper case. The ring-shaped groove portion 18 formed in the eleven treatment portions B is fitted and attached. In the mounted state, the screw fixing boss portion 22c formed on the inner side surface of the peripheral wall portion 22b engages with the screw insertion portion 12d formed so as to cut the cover mounting portion 12c from the ring-shaped groove portion 18. And function as a detent.
[0050]
Then, the cover 21 is supported by being sandwiched between the biting portion 22d in which the peripheral portion of the hole 22a is protruded slightly downward and the distal end portion of the partition wall 12b formed around the treatment body receiving portion 12a ( FIG. 6). Further, a large number of ribs 22e are formed on the inner surface side along the circumferential direction, and each rib 22e is provided with a cutting step portion 22e ', and the notch is pressed while strongly pressing the peripheral portion of the cover 21. The part is made to escape the peripheral part to prevent wrinkling.
[0051]
The massaging device A having the above-described configuration is characterized in that the two geared motors M are stopped when one geared motor M is overloaded.
[0052]
Therefore, in this embodiment, the circuit configuration shown in FIGS. 15 and 16 is employed. FIG. 15 shows a circuit of the switch side substrate 3a of the two substrates 3a and 3b, and FIG. 16 shows a circuit of the power source side substrate 3b. The circuit is shown as a block diagram in FIG.
[0053]
In this embodiment, an overcurrent detection circuit 7 for detecting an overload applied to each geared motor M as an overcurrent is provided in the above circuit, and both motors M and M are stopped when an overcurrent is detected in any geared motor M. Like to do.
[0054]
Then, the controller 8a and the timer 8b are provided and connected in the circuit, and when the massage device A is driven and 15 minutes elapses, the timer 8b is increased and the controller 8a is reset so that the controller 8a is reset. When the detection unit including the current detection circuit 7 detects an overcurrent, the timer 8b is forcibly increased and the control unit 8a resets the whole. The overcurrent detection circuit 7 includes a resistor 8f having a resistance value of 0.5 Ω for converting the overcurrent of the geared motor M into a current voltage, and an amplifier 8c and a comparator 8d for amplifying the signal by 10 times.
[0055]
That is, a current of 0.1A flows through the input circuit (resistor 8f) to the amplifier 8c in the no-load state, but in a normal load state, for example, when a foot or the like is placed on the treatment part B, a current of 0.2 to 0.3A Further, the current value is about 0.5 A at the time of an abnormal load in which the geared motor M must be stopped.
[0056]
Since the resistance value of the resistor 8f for current-voltage conversion is 0.5 Ω, the voltage is 0.05V when there is no load, 0.1 to 0.15V under load, and 0.25V under abnormal load. Since this value is too small, it is amplified 10 times by the amplifier 8c and input to the comparator 8d.
[0057]
On the other hand, 2.5 V is applied as a reference voltage to the comparator 8d. Therefore, when the voltage exceeds 2.5 V, the motor drive stop signal is output and the geared motor M is stopped. .
By adopting such a configuration, for example, when the cover 21 of the treatment body 2 is torn, if the user accidentally pushes a finger or the like into the acupressure rotator 20 and is caught, the overcurrent detection circuit 7 However, it is safe because the geared motors M and M are stopped when the overcurrent of the geared motor M is detected.
[0058]
In this embodiment, a delay circuit 9 is provided for delaying the output of the overcurrent detection signal for a predetermined time.
[0059]
In other words, a first delay circuit 9a for starting the motor is provided between the overcurrent detection circuit 7 and the timer 8b to prevent a malfunction that prevents the inrush current from being detected immediately after the start and cannot be driven. A second delay circuit 9b for stopping the motor is provided between the timer 8b and the control unit 8a so that the motor does not stop frequently due to noise or the like during driving.
[0060]
FIG. 18 shows a time chart of the massage device A from on to off.
[0061]
Fig. 18 (a) shows the case where the power switch 5 is turned off, Fig. 18 (b) shows the case where the time has been turned off, and Fig. 18 (c) shows the case where the overload is detected and forcibly turned off. ing.
[0062]
(a): When the power switch 5 is turned off
When the power switch 5 is turned on (100), the geared motor M and the timer 8b start to drive. At this time, the first delay circuit 9a acts to output a mask signal, and the geared motor M does not stop even if an inrush current is detected within the output time (3 seconds in this embodiment) (110). .
[0063]
When the timer 8b continues to count (120) and the power switch 5 is turned off in the middle (130), the timer 8b is cleared, (140), the power is cut off (150), and the geared motor M is stopped. .
[0064]
(b): When time is up and off
When the power switch 5 is turned on (200), the geared motor M and the timer 8b start to drive. At this time as well as in the case of (a), the first delay circuit 9a acts to output a mask signal, and within the output time (3 seconds in this embodiment) (210), even if an inrush current is detected. The geared motor M does not stop.
[0065]
Then, the timer 8b continues to count (220), and when the set time of 15 minutes elapses (230), from the motor stop signal output terminal (OUT1) of the timer 8b to the motor stop signal input terminal (R1) of the control unit 8a. The time-up signal 240 is output with a slight delay (several milliseconds in this embodiment) via the second delay circuit 9b (250), the timer 8b is cleared (260), and the geared motor M stops ( 270).
[0066]
(c): When overload is detected and forcibly turned off
In this case as well, when the power switch 5 is turned on (300), the geared motor M and the timer 8b start to drive, and the first delay circuit 9a acts to output a mask signal and output time (3 seconds in this embodiment). The inner (310) does not stop the geared motor M even if an inrush current is detected.
[0067]
Then, the timer 8b continues counting (320), and if an overload occurs in one or both of the two geared motors M, the overcurrent detection circuit 7 detects this and outputs a detection signal ( 330), the motor stop signal output terminal (OUT1) of the timer 8b is delayed from the motor stop signal input terminal (R1) of the controller 8a through the second delay circuit 9b for a short time (several milliseconds in this embodiment). When the time-up signal 340 is output (350), the timer 8b is cleared (360) and the geared motor M is stopped (370).
[0068]
As described above, the massage device A according to the present embodiment starts stably without being affected by the inrush current immediately after the power switch 5 is turned on, and is not affected by noise in use. Since the overload applied to the treatment body 2 can be detected and the two geared motors M can be stopped at the same time, it is possible to greatly improve the safety without impairing the usability.
[0069]
The massage device A can also be provided with a sounding means.
[0070]
That is, as shown in FIG. 19, immediately after the power switch 5 is turned on, the first delay circuit 9a acts to output a mask signal (3 seconds in this embodiment) and emits an electronic sound or the like. In addition, the start of the massage device A is notified (400), and the melody flows within the usage time, so that the relaxed feeling can be strengthened and the massage effect can be further enhanced.
[0071]
In the case shown in FIG. 19, when weak is selected by the strong / weak selector switch 6, (410) ballad-like music flows (420), and when strong is selected (430) rock-like music flows. (440).
[0072]
Furthermore, from one minute before the time is up (450), “It's about one minute.” Or “It's about to end.”
[0073]
In FIG. 19, 460 is a time-up signal.
[0074]
Further, in the case of such a configuration, it is preferable to provide a function for turning off the sound generation means and the like for use at midnight or the like.
[0075]
The above is just an example, and the selection and setting of the sound generation means in the use state is free. For example, at the start of the rise of the massage device A, it can be notified by a voice such as “Start” instead of the electronic sound.
[0076]
Further, when an overcurrent is detected, an abnormal load can be notified at a level corresponding to the magnitude of the overcurrent.
[0077]
In the case shown in FIG. 20, the abnormal load applied to the geared motor M is notified by the light emitting means in addition to the sound producing means.
[0078]
That is, the sound generation means periodically generates a sound at intervals of 1 second (500), or blinks light with an LED or the like (510), and the abnormal load increases (520). For example, the notification period is gradually shortened so as to be 0.5 seconds (530). When a dangerous load is detected (540), the sounding means emits a continuous sound (550), and the light emitting means is continuously lit (560). Note that when a dangerous load is detected, the geared motor M naturally stops.
[0079]
Furthermore, in addition to performing the control as described above, the massage device A can be configured not to be activated for a predetermined time after an overload is detected and an emergency stop is performed.
[0080]
That is, after the overcurrent is detected and the timer 8b is forcibly increased to cause the geared motor M to stop urgently, control is performed so as not to restart for a predetermined time.
[0081]
In this embodiment, as shown in FIG. 21, a second timer 8e is provided. The second timer 8e operates after an emergency stop, and the power switch is used for t seconds (for example, 10 seconds) after the motor stops. The geared motor M is prevented from being driven even if 5 is turned on again. Therefore, it is safe even if the power switch 5 is mistakenly operated when the user pinches the finger between the treatment bodies 2.
[0082]
At this time, in this embodiment, as shown in FIG. 20, the sounding means and the light emitting means are continuously notified (570). Note that sound and light can be used alone as notification means, or may be used together, but they are useful notification means for visually impaired persons if they are sound and for hearing impaired persons if they are light. .
[0083]
In FIG. 20, 580 is a delay time of several milliseconds by the second delay circuit 9b until the geared motor M stops, and in FIG. 21, S is a speaker of the sounding means and the sounding means.
[0084]
In the present embodiment, the driving means of the treatment body 2 has been described as the geared motor M in which the motor and the reduction gear for reducing the rotation of the motor are integrally connected. It doesn't matter if it doesn't exist. Further, the number of drive units arranged is not limited to two, and may be larger.
[0085]

[0086]
In FIG. 22, while sitting on a chair C, the massager A is positioned between the backrest C1 and the user to massage the back and waist. Thus, since the backrest part C1 can be utilized, if a power adapter for automobiles is used, a massage can be easily performed even in an automobile. For example, in the case of long-distance driving, if fatigue is recovered by massaging during a break time or the like, a drowsy driving or the like can be prevented, leading to safe driving.
[0087]
Moreover, in FIG. 23, the neck muscle is massaged. At this time, since the concave portion 13 is provided in the case main body 1, the corner portion of the case main body 1 does not come into contact with the shoulder or the neck portion, so that there is no possibility of giving unpleasant feeling. Thus, this massage device A is very convenient to use when massaging a constricted part of the body.
