Massage is to control the modulation of the subject's body by applying various types of mechanical stimuli to the subject's body part, such as kneading, pressing, pulling, tapping, or moving the subject's body part. It is a medical adjuvant therapy that helps circulation and relieves the fatigue of the subject.

The increase in massage demand has caused an increase in demand for a massage device or a massage device that provides an artificial massage function due to economic circumstances and time reasons. That is, as the demand for relieving fatigue or stress while relaxing the tense muscles through massage increases, various massage devices in a time- and cost-effective manner are being released. Any type of apparatus, device or apparatus for performing massage through a mechanical device without a separate masseuse is referred to as a massage device.

Such a massage device can massage various parts of the body, such as arms and legs, and among them, the demand for foot massage is increasing. Since each user has a different area to be massaged, it is necessary to provide a massage that meets the user's needs.

The movable bracket 63 is in the form of a square flat plate and is slidably installed in the front and rear directions between the guide member 50 and the base part 10 . One end of the movable bracket 63 is connected to one end of the cam housing 62 via a connecting pin 64, and linear reciprocating motion in the front and rear directions on the base portion 10 by the front-rear movement of the cam housing 62 do.

A plurality of inclined cams 65 on which the main acupressure bar 31 and the sub acupressure bar 32 are seated are integrally formed on the upper surface of the movable bracket 63 . Therefore, when the movable bracket 63 moves linearly in the front-back direction, the main acupressure bar 31 and the sub acupressure bar 32 rise or fall along the inclined surface of the inclined cam part 65 . The plurality of inclined cam parts 65 may have the same inclined direction, but as in this embodiment, some inclined cam parts 65 have the opposite inclined direction so that when some acupressure rods 31 and 32 rise, the remaining acupressure rods ( 31, 32) can be made to descend.

On the other hand, the main acupressure rod 31 moves up and down by the inclined cam part 65 when the movable bracket 63 moves forward and backward, and at the same time rotates about its central axis by the acupressure rod rotating means to pressurize the Yongcheonhyeol region of the sole of the foot. configurable.

As such, the acupressure rod rotating means for imparting a rotational force to the main acupressure rod 31 is the moving direction of the movable bracket 63 on one side of the inclined cam part 65 on which the main acupressure rod 31 is seated in the movable bracket 63, that is, before and after. The rack gear 66 installed to extend along the direction, and the pinion gear installed to mesh with the rack gear 66 at the lower part of the main acupressure rod 31 and rotated by the linear motion of the rack gear 66 . (67). The rack gear 66 and the pinion gear 67 may be configured by applying a spur gear, but may be configured by applying a helical gear as shown in FIG. 8 .

In this embodiment, the acupressure rod rotating means consists of a rack gear 66 and a pinion gear 67, but as shown in FIG. 12 in another embodiment, the acupressure rod rotating means is spirally formed on the outer surface of the main acupressure rod 31. The formed rotation guiding groove 33, and a rotation operation protrusion 55 protruding spirally from the inner circumferential surface of the acupressure rod guide hole 51 of the guide member 50 and inserted into the rotation guiding groove of the main acupressure rod 31 may include. have.

On the other hand, in order to accurately detect the positions of the rotating acupressure body 20, the main acupressure bar 31, and the sub acupressure bar 32 to control the massage pattern in various ways, as shown in FIGS. 10 and 11, a plurality of The encoding disk 71 in which the encoding holes 73 are formed at regular intervals along the circumferential direction is coupled to the rotation shaft 21 and rotates together with the rotation shaft 21, and the base part 10 of the encoding disk 71 of An encoder 72 for detecting the rotational position of the rotating shaft 21 may be installed by detecting the encoding hole 73 .

The encoding disk 71 has a disk shape in which a plurality of encoding holes 73 are formed at regular intervals along the circumferential direction, and the central portion is coupled to the rotation shaft 21 to rotate together with the rotation shaft 21 . In addition, a plurality of encoding slits 74 having a long hole in the circumferential direction may be provided with a predetermined length in the encoding disk 71 to assist the position detection.

The encoder 72 has a 'C' shape so that the encoding disk 71 can be inserted, and the light (for example, a laser beam) emitted from the light emitting part on one side is the encoding hole 73 of the encoding disk 71 . It is possible to accurately recognize the positions of the rotating acupressure body 20, the main acupressure bar 31, and the sub acupressure bar 32 by detecting the amount of rotation and the rotation speed of the rotating shaft 21 by detecting that it passes through and is incident on the light receiving unit.

This foot massager works as follows.

When a control signal is applied to the driving motor (not shown) through the controller of the massage chair or the controller of the foot massage device to operate the driving motor, the rotational force of the driving motor is transmitted to the rotating shaft 21 through the reduction gearbox and the rotating shaft 21 ) and the rotating acupressure body 20 is rotated.

As the rotary acupressure body 20 rotates, the sole of the foot is pressed by the curved irregularities or acupressure projections of the rotary acupressure body 20 . At this time, since the vertical size of the inner portion of the axial direction of the rotary acupressure body 20 is formed larger than the outer portion, even the concave portion of the sole of the foot can be effectively pressed.

As shown in Figures 9a and 9b, as the rotary pressure body 20 rotates, the eccentric cam 61 rotates, and the cam housing 62 to which the eccentric cam 61 is coupled swings in the front-rear direction. do. The front-rear movement of the cam housing 62 is transmitted to the movable bracket 63 so that the movable bracket 63 linearly reciprocates with respect to the base part 10 in the front-rear direction.

Since the main acupressure bar 31 and the sub acupressure bar 32 are seated on the inclined cam part 65 on the movable bracket 63, the main acupressure bar 31 and the sub acupressure bar 32 are inclined as the movable bracket 63 moves forward and backward. While reciprocating up and down along the inclined surface of the cam part 65, the sole of the foot is pressed. At this time, the main acupressure rod 31 pressurizes the Yongcheonhyeol portion of the sole while simultaneously lifting and rotating by the action of the rack gear 66 and the pinion gear 67 .

As described above, in the foot massage device of the present invention, since the rotating acupressure body 20 rotates and the main acupressure rod 31 and the sub acupressure rod 32 move up and down while pressing the sole of the foot, the acupressure effect can be improved. There is an advantage.

In addition, since the rotational motion of the rotating acupressure body 20 is converted into the vertical motion of the main acupressure rod 31 and the sub acupressure rod 32 by the motion conversion unit, the rotational movement of the rotating acupressure body 20 and It is possible to generate vertical movement of the main acupressure rod 31 and the sub acupressure rod 32 .
