It is a flexible spiral cord that can expand and contract. An elongated remote controller 31 is connected to the cord 30 of the spiral. The spiral cord 30 is a multi-core cord formed by covering a power line for transmitting electric power of a DC power source for driving an electronic circuit (not shown) built in the remote controller 31 and a signal line for transmitting a control signal.

As shown in FIG. 4, the remote controller 31 displays the operation unit 32 such as a plurality of push buttons for selecting the operation mode of the massaging device M, the power button 35, and the selected mode by a lighting operation. A display unit 33 for displaying and display characters are provided, and a control signal is sent to the control device 22 by operating the operation unit 32.

The thickness of the remote controller 31 is formed to be smaller than the depth of the remote controller housing recess 4, and is housed in the remote controller housing recess 4 in a detachable manner. The cord bush 36 provided at the connecting portion between the remote controller 31 and the spiral cord 30 is removably fitted into the groove 4a formed at one end of the remote controller housing recess 4, and the fitting allows the remote controller housing to be accommodated. The remote controller 31 is positioned with respect to the recess 4.

The two massagers 21A and 21B have the same configuration and are configured as shown in FIG. That is, reference numeral 41 in these drawings denotes a motor mounting frame which is fixed to the case member 2 at the three positions with the above-described vibration-proof structure, to which a motor 42 with a commutator is mounted, A spring receiving portion 43 located integrally with the output shaft 42a of the motor 42 is provided integrally therewith. One end of a first coil spring 44 for transmitting torque is fixed to the output shaft 42a, and an eccentric weight 45 having a center of gravity at a position eccentric to the axis of the spring 44 is fixed to the other end of the spring 44. It is fixed.

The eccentric weight 45 is housed in the head frame 46 and rotatably supported by the frame 46 via a bearing 47. The head frame 46 has a substantially cylindrical shape with both ends closed, and a spring bearing portion 48 facing the spring bearing portion 43 is provided on one end wall of the head frame 46 on the motor 42 side. The ends of the second coil spring 49 are fitted and fixed in the spring receiving portions 43 and 48, respectively. The second coil spring 49 is for urging to obtain the pressing force of the vibrator to the affected area, and the head frame 46 is cantilevered by the spring receiving portion 43 via this spring 49. The first coil spring 44 is passed through the second coil spring 49 along the axial direction.

A head mounting portion 46 a formed on the head frame 46 is mounted with a heating element 51 having a heating element 50 for thermal treatment composed of a posistor, and the heating element 51 is covered to form an aluminum die. A metal head 52 made of cast or the like is attached. The head 52 is provided with a pair of large and small projections 53 and 54 having different diameters and a hemispherical tip.

The eccentric weight 45, the head frame 46, the bearing 47, the heating element 51, and the head 52 form a vibrator 55 serving as an acupressure element supported via the second coil spring 49. There is.

The vibrators 55 of both massaging devices 21A and 21B are provided so that the large-diameter projections 53 of the head 52 are located close to each other and the small-diameter projections 54 are located far from each other, as shown in FIG. ing. The interval between the protrusions 53 is set to be approximately the same as the interval between the acupuncture points which are located so as to sandwich the spine of the acupuncture points of the back on both sides of the user's spine.

Due to the mutual arrangement of the heads 52, the protrusion 54 having a small diameter is mainly used when sitting on a chair and massaging the arch of the foot, and the contact between the both feet is eliminated, and the arch of the foot is not contacted. It is possible to prevent the arch from being excessively overloaded by depositing the weight on the chair, even though the protrusion 54 having a small contact area is used for the massage. Further, when massaging an affected area such as the back or the waist, a large-diameter projection 53 is mainly used to secure a large contact area to the affected area, and it is possible to prevent the affected area from becoming too painful due to the effect of weight. .

As representatively shown in FIG. 1, the heads 52 of the vibrators 55 included in the massaging devices 21A and 21B having the above-described configurations are separately passed through the through holes 11a and 11b, respectively, and the main body case 1 Is projected out of. The head 52 of the vibrator 55 is always in contact with the inner surface of the cover 12 by the spring force of the second coil spring 49, and pushes up the cover 12 to maintain the tension state.

As shown in FIG. 4, the longitudinal distance E between the pair of vibrators 55 and one end of the main body case 1 on the concave portion 7 side is equal to that of the pair of vibrators 55 and the concave portion 8 side of the main body case 1. It is smaller than the longitudinal distance F between the other end. The distance E is set to such a length that the pair of vibrators 55 correspond to the height of the waist of the sitting user when the main body case 1 is erected with the concave portion 7 facing downward. F is set to a length such that the pair of transducers 55 correspond to the height of the portion between the body case 1 and the scapula hips on the back of the seated user when the body case 1 is erected downward. ing.

As shown in FIGS. 1 and 7, an elastic body 61 made of sponge rubber or the like is sandwiched between the bottom wall of the case member 2 of the main body case 1 and the vibrator 55. . The elastic body 61 is elastically deformed while being compressed when the vibrator 55 is pushed by the affected area, and the elastic force biases the vibrator 55 toward the affected area. Reference numeral 62 in FIGS. 1 and 6 denotes a connecting plate which is laid across a pair of vibrators 55, and prevents the vibrators 55 from being twisted due to the second coil spring 49, and corrects the affected parts. It is provided to obtain the pressing state. Further, reference numeral 63 in FIG. 6 denotes a reflection type photo switch fixed to the inner surface of the case member 2, which is turned on when the reflected light from the connecting plate 62 is received, and is a motor for both the abraders 21A and 21B. The 42 is supposed to start at the same time.

Further, the main body case 1 in which both the massaging devices 21A and 21B are incorporated is provided with a breathing port 2a located near the motor 42 of the massaging devices 21A and 21B. The breathing port 2a is composed of, for example, a large number of slit holes arranged side by side, and in the case of this embodiment, as shown in FIGS. 1 and 5 to 7, the case member 2 has a circular arc-shaped wall portion. Has been formed. Therefore, the internal space 1a of the body case 1 communicates with the outside of the body case 1 substantially only through the breathing port 2a.

Since the massaging device M having the above-described configuration has the cover 12 that covers the through holes 11a and 11b of the main body case 1, it is possible to prevent dust and the like from entering the main body case 1 through the through holes 11a and 11b. In addition, the appearance of the entire massaging device M can be improved by eliminating the visual confirmation of the through holes 11a and 11b and the vibrator 55.

The massaging device M is mainly used as a foot massager. At this time, the user C sits on a chair as shown in FIG. 9 (A) and puts the arches of both feet on the pair of transducers 55 via the covers 12 separately. Then, as the vibrator 55 is pushed down by the weight of the foot, the connecting plate 62 intersects the optical path of the photo switch 63, so that the switch 63 receives the reflected light from the connecting plate 62 and is turned on. As a result, the motors 42 of the pair of massaging devices 21A and 21B are activated.

Therefore, since the output shaft 42 a of the motor 42 rotates the eccentric weight 45 via the first coil spring 44, the entire vibrator 55 vibrates with this rotation, and this vibration causes the head to vibrate. 52 is transmitted to the arch through the cover 12 so that the soles of both feet can be massaged respectively.

When used as a foot massager in this way, the remote control storage recess 4 (whether or not the remote controller 31 is stored) between the pair of vibrators 55 is seated on a chair. The user's C foot can be used as a guide when placing the foot of the user C on a fixed position, that is, on the pair of massage parts 5 and 6, respectively. It is useful. Even if the remote controller 31 is housed in the remote controller housing recess 4, since the thickness of the remote controller 31 is smaller than the depth of the remote controller housing recess 4, the remote controller 31 housed in the remote controller housing recess 4 is It does not get in the way when the foot is placed on the main body case 1 by being projected onto the remote control storage recess 4. Therefore, both feet can be easily set (placed) on the pair of vibrators 55, respectively.

Further, as shown in FIG. 9B, the calves of both feet can be massaged by placing the calves of both feet separately on the pair of transducers 55 while sitting on the floor. .

Then, as shown in FIG. 9 (C), in a state of sitting on the chair, the massage device M is inserted between the back of the chair and the back of the chair, with the concave portion 7 thereof facing upward, By leaning on the back, the motors 42 of the pair of massaging devices 21A and 21B can be activated and the back can be massaged by the pair of vibrators 55.

Similarly, the massage device M is inserted between the backrest and the waist of the chair with the recess 7 facing downward, and the pair of vibrators 55 are vibrated respectively by leaning against the backrest. You can massage the lower back.

When using FIG. 9 (C), the remote controller 31 is detached from the remote control accommodating recess 4 and placed at the user C's hand. Therefore, if the operation mode is changed during this use, the operation can be performed by hand operation, and the massaging device M can be taken out from between the backrest of the chair and the upper body of the user C to operate the operation mode. There is no need to change the mode. Also, when using FIG. 9B, it is possible to drive with the remote controller 31 at hand.

When the massaging device M as described above is used, regardless of whether the cover 12 is in contact with the affected area or not, the vibrator 55 in contact with the inner surface of the cover 12 vibrates. The flexible cover 12 is moved to breathe. By the way, the main body case 1 in which the through holes 11a and 11b are closed by the cover 12 and the vibrating massaging devices 21A and 21B are incorporated has the breathing port 2a, and substantially only the breathing port 2a is passed through to the case body. 1 has an internal space 1a communicating with the outside. Therefore, the air moves in and out of the case body 1 through the breathing port 2a with the breathable movement of the cover 12.

Since the breathing port 2a is provided near the motor 42 of the vibration type massagers 21A and 21B, the motor 42 can be exposed to the flow of air accompanying the breathing. Therefore, the motor 42 can be forcibly cooled by air and its temperature rise can be suppressed.

In particular, in the case of massaging the heating elements 50 of the massaging devices 21A and 21B to generate heat while applying heat to the affected area, the heat escaping to the periphery of the vibrator 55 can be swiftly supplied by the air flowing in and out of the body case 1. Since it can be discharged to the outside, the durability of the massaging devices 21A and 21B can be improved without fear of the temperature rising further.

The present invention is not limited to the above-mentioned embodiment. For example, only one massager may be used. Further, when the vibrators 55 form a pair, it does not matter if one and the other of the pair of vibrators 55 are plural respectively, and the motor part of the massaging device is shared by the pair of vibrators 55. Alternatively, the through holes 11a and 11b of the main body case 1 may be a single through hole.

[0043]

[Effect of device]

 As described above in detail, according to the massaging device of the present invention, the vibration of the vibrator of the vibration type massaging device moves the cover that covers the through hole of the main body case to allow the breathing device located near the motor of the vibration type massaging device. Air is passed in and out of the main body case through the mouth, and the air flow cools the motor. Therefore, the temperature rise of the vibration type agitator can be reduced, and the through hole and the vibrator are not visually recognized by the cover. , The appearance of the entire massager can be improved.
