Description

1247603 V. INSTRUCTION DESCRIPTION α) [Technical Field of the Invention] The present invention relates to a foot massager, and more particularly to a massager that massages the inside of a foot by applying vibration to the vibration. [Prior Art] The capillaries of the peripheral nerves and arteries are concentrated in the human foot. Therefore, pressing a large number of acupuncture points distributed in the foot to stimulate the peripheral nerves, while promoting blood circulation, thereby eliminating fatigue and activating the functions of various organs of the body has been known since ancient times, so the shiatsu and the stepping bamboo in the foot Therapies for health promotion are also widespread. Moreover, in order to easily implement the above-mentioned finger pressure inside the foot and to improve the effect, the proposal has replaced the bamboo method since ancient times, and the electric massager is used to stimulate the massager in the foot. As shown in FIG. 10, the massager has a driving mechanism b for driving the footrest a up and down by the rotation of the electric motor m and a pressing magazine c on the side of the footrest a of the pivotal toe side. The elastic mechanism g comes to the branch. The driving mechanism b includes a rotating shaft b transmitted by the rotation of the electric motor ra through the belt speed reducing mechanism e, an eccentric portion b 2 formed by eccentricity of the central axis with respect to the rotating shaft b1, and a lower end pivoted by the eccentric portion b 2 and The upper end is pivoted to the shaft of the footrest a. Therefore, in the massager, the tie bar b 3 is moved up and down between the top dead center h 1 and the bottom dead center h 2 by the rotation of the electric motor m, whereby the footrest generates up and down vibrations, and the result is as described above. The shock stimulates the foot placed on the footrest a. The elastic mechanism g is formed by a pressing spring c that is disposed in a lower portion of the ankle portion of the footrest a portion in a direction in which the expansion and contraction direction is perpendicular to the upper portion.

Page 5 1247603 V. INSTRUCTIONS (2) Force against the weight of the user who applies the load on the footrest a, pushing the carrier a upward. Thereby, the driving load of the electric motor m is reduced. However, when the inside of the foot is pressed, the pressing force toward the deepest indentation position in the foot is increased, which can effectively stimulate the nerves of the nerve and promote the blood circulation. Therefore, when the massager raises the footrest a, the force is placed on the inside of the foot, and the speed of the rise is increased, and the inside of the foot is strongly pressed, thereby improving the stimulation of the nerves of the distal end, and the massage The effect is significant. However, in the previous massager, as the footrest a rises, the pressing spring c will elongate to reduce the elastic force. As shown in FIG. 10, the elastic force f 1 in the top dead center h 1 is lower than the bottom dead center h The elastic force f 2 at 2 places is small. Therefore, when the footrest a rises to the top dead center h1, the force of pressing the inside of the foot is lowered, and as the elastic force is lowered, the driving load of the electric motor m is increased, so the rotation speed is lowered. As a result, even if the vibration is applied to the inside of the foot, the pressing force and the pressing speed at the time of raising the foot of the massage focus are insufficient, for example, the massage effect cannot be obtained even if the treatment is applied for a long time. SUMMARY OF THE INVENTION The main object of the present invention is to provide a foot massager that solves the drawbacks of a conventional massager. The driving portion for moving the footrest up and down is provided with: an electric motor; and a lifting mechanism that moves up and down by rotation of the motor. The foot seat, and as the footrest rises from the lower position to the upper position, the strength is increased, and the massager can obtain the massage effect in a short time. In order to achieve the above object, the present invention mainly comprises a base and a carrier supported by the base and movable up and down, and is disposed on the base and drives up and down.

Thermal method is fully obtained

1247603 V. INSTRUCTION OF THE INVENTION (7) The elastic support portion 26 is attached to the lift plate 9 and the base 2, respectively, as shown in Figs. 2 and 3, and is disposed on the ankle side of the lift plate 9. One pair of connecting rods 6, 6 on both sides of the end portion, and a tensile magazine 8 attached to the aforementioned connecting rod 6. In the present embodiment, as shown in FIGS. 3 and 6, the connecting rod 6 includes a pair of lower links 6 L, 6 L, and the lower end portion is pivoted through the lower fixing member 3 8 L to support the shaft P 3 . The base 2; and a pair of upper links 6 U, 6 U, the lower end portion is pivoted by the upper end portion of the lower link 6 L by a pivot point 7 formed by a screw, and the upper end portion is passed through the upper fixing member 3 8 U is pivoted to the aforementioned lifting plate 9 with a support shaft P 4 . In the present embodiment, the upper link 6 U and the lower link 6 L are of the same length, so that the link 6 has a diamond shape. Further, the lower links 6 L, 6 L may be opened upward, and the lower ends thereof may be spaced apart from each other and pivoted to the base 2, and the upper links 6 U, 6 U may also be width-widthed. The upper side is narrowed, and at the same time, the upper end portion is disposed to be spaced apart from the lifting plate 9. Further, the upper link 6 U and the lower link 6 L may have different lengths. Since the connecting rod 6 has a pantograph shape, as shown in Fig. 6, the movement between the support shafts P3 and P4 is increased and decreased in conjunction with the vertical movement of the lifting plate 9, and at the same time, the left and right pivot points 7 and 7 are The interval W will decrease or increase. Further, the tension spring 8 is stretched between the left and right pivot points 7, 7 which are increased or decreased by the interval W. As shown in Fig. 7, the elastic force F constantly presses the link 6 to reduce the pivot points 7, 7 Move in the direction of the interval. As a result, in the above-described connecting rod 6 in the form of a pantograph, the aforementioned elastic force F generates a force Ρ which increases the distance between the Ρ3 and Ρ4, and the lifting plate 9 is pressed up by the aforementioned force Ρ. The weight of the loader applied to the lifting plate 9 to be massaged is partially supported by the elastic support portion 26 to raise

Page 11 1247603 V. INSTRUCTIONS (8) The load of the motor Μ that moves the lowering plate 9 up and down is reduced, so that a certain massage vibration can be smoothed, and a small motor Μ can be used. When the interval W becomes smaller by the rise of the lift plate 9, the length of the tension spring 8 becomes shorter, so that the elastic force F of the push link 6 is reduced. However, as a result of the force vector synthesis of the link 6, the force of pressing the lift plate 9 increases as the lift plate 9 rises. Therefore, during the vibration process, the foot portion 3 rises, and the foot portion 10 cooperates with the time point when the foot portion is deeply pressed, and the foot portion is pressed more strongly. As a result, the end of the foot can be effectively stimulated. It is slightly nerved and activated, and at the same time, it can promote blood circulation and significantly improve the massage effect. Further, when the lift plate 9 is raised, the load of the motor cymbal is reduced and the rotational speed is accelerated. Therefore, when the foot portion 10 is deeply pressed into the inside of the foot portion, pulsating pressurization occurs, even for a short time. A significant massage effect can also be obtained by using it. The massager 1 of the present embodiment controls the operation by a control unit 39 including a transformer, a rectifier, a timer, and the like. The control unit 39 is connected to a household 1 10 V power source by a wire (not shown) to drive the motor Μ. The massager 1 controlled by the control unit 39 receives the switch 0 讯 signal and supplies power to the motor 如 as shown in Fig. 9, whereby the vibration is started and massage is performed. Further, when the timer is activated by the set time or the switch 0 F F signal is received, and the power supply to the motor is stopped, the vibration is stopped and the massage is ended. The switch operation portion 14 for transmitting the switching signal is disposed at an upper end portion of the columnar portion 40 which is erected on the toe side of the susceptor 2, and is disposed at an elasticity provided between the foot portions 10, 10 of the cover body 1 The inside of the cover body 4 1 . The aforementioned switch operating portion 14 because

Page 12 1247603 V. Inventive Note (9) It is placed between the foot and the foot of the foot part 10, so it can be easily opened and closed by the foot of the foot part 10, and the operability is excellent. When the eccentric distance d is 1 mm, the lifting plate 9 and the susceptor 2 which are moved up and down by the crank mechanism portion 34 having a distance between the top dead center and the bottom dead center of 2 mm are formed and mounted according to the first table. An embodiment of the elastic support portion 26 formed as shown in Fig. 6 and shown. The connecting rod 6 of the present embodiment is interlocked as the lifting plate 9 moves up and down, and the height of the connecting rod which is the distance between the supporting shafts P3 and P4 is centered at 29 mm at the intermediate point, at the top dead center of 30 mm and the bottom dead center. 2 8mm repeatedly increase and decrease deformation. The aforementioned tension spring 8 stretched between the pivot points 7 of the link 6 is expanded and contracted by the above-described deformation, and the link 6 presses the lift plate 9 in accordance with the elastic force F. In the foregoing embodiment, at the top dead center, the bottom dead center, and the intermediate point, the elastic support portion 26 is obtained by simulating the force P of the upper lift plate 9. As a result, as shown in Fig. 8, the bottom dead center is 4 9 · 8 2 N, the intermediate point is 5 0 . 9 8 N, and the force P at the top dead center of 5 2 β 0 9 N is simulated, and the upper pressure can be confirmed. The force of the lifting plate 9 is gradually increased as the lifting plate 9 rises. In summary, the driving portion of the footrest that moves up and down in the present invention has an electric motor and an elevating mechanism, and the footrest is moved up and down by the rotation of the motor, and as the footrest rises from the lower position to the upper position. Increase the strength. Therefore, the shocking foot of the foot rises and presses deeply toward the inside of the foot, and at the same time, the foot can be pressed with a large force, and as a result, the nerve is stimulated and the blood circulation is promoted, even for a short period of time. A significant massage effect can also be obtained.
