Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides for repeatedly driving a massager, particularly an actuating body,
The present invention relates to a massage device that uses the elasticity of a spring to repeatedly strike the skin surface and to easily adjust the strength of the bounce to a large extent.

BACKGROUND ART Conventionally, as a massage method for facial beautification treatment, repeatedly tapping or flicking the face with fingertips or the like has been carried out.

An object of the present invention is to provide a massage device that can perform the above-described flicking motion repeatedly by determining the position using the elasticity of the spring, in order to apply the flicking motion to, for example, the back or shoulders. There is.

Various devices have been known as massage devices that apply vibrations to the skin surface, but the massage device of the present invention secures a distance between the main body device and the skin surface using a base guide, and The plate body and the buffer body attached to the actuating body are configured to slightly protrude from the end face of the space guide, and are essentially configured to flick the skin surface, that is, to flick the skin surface in a puff-like manner. There are differences. As mentioned above, the massager of the present invention is used to hit the back and the like, but it is necessary to adjust the strength of the slap depending on the area to be massaged.

Therefore, the massage device of the present invention is configured so that the force of hitting is adjusted by giving a deflection to the spring in advance, and by adjusting the deflection (hereinafter referred to as initial deflection), the above-mentioned repulsion can be achieved. The object of the present invention is to provide a massage device that can change the strength of the beating. In addition,
It is desirable that the strength of the above-mentioned flicking can be adjusted within a wide range as necessary. To this end, as will be described later, consideration should be given to reducing the spring constant of the spring and widening the adjustment range of the initial deflection. However, increasing the adjustment range of the initial deflection is not preferable because the adjustment mechanism becomes complicated and the device itself becomes large. Another object of the present invention is to use two springs in series so that one of the two springs does not deflect by more than a predetermined distance during the adjustment. To provide a massager capable of reducing the adjustment range of deflection and increasing the adjustment range of the strength of the flicking.

This will be explained below with reference to the drawings.

FIG. 4 is an enlarged view for explaining the adjusting means for adjusting the energy in the present invention.
An explanatory diagram for explaining the relationship between the accumulation amount and the adjustment amount by the adjustment means is shown. In the figure, 1 is the main unit, 2 and 2'' are handle parts, 3 is a connecting arm, 3'' is a hook part that is formed integrally with the connecting arm 3, 4 is an actuating body, 5 and 6 is a buffer ring, 7 is a plate which is attached to the operating body, 8 is a buffer which is attached to the plate 7, 9 is a space guide,

Reference numeral 8 denotes a spring, 19 a sprocket catch which is fixed to the actuating body 3 and supports the spring 17, and 20 a spring intermediate catch which is fixed to the actuator 3 and supports the spring 17 and the spring 17. those who support 18;
21 is a spring strength adjustment knob, 22 is an adjustment knob shaft, 2
3 to 26 are gears, 27 is a spring strength adjustment screw,
28 is a spring pressing part, 29 is a housing cylinder for the spring pressing part, and 30 is a guide groove, which is connected to the spring pressing part 2.

The main body device 1 includes handle portions 2 and 2'', and is configured, for example, in the shape of a pistol, so that it can be operated with one hand.

A motor 10 is provided within the handle 2, and a drive shaft 12 is rotated via a speed reducer 11. A rotating disk 13 is fixed to the drive shaft 12, and rotation of the drive shaft 12 causes the rotating disk 1 to rotate.
3 is rotated. A roller 1 is rotatably mounted on the rotating disk 13.
4 and 14'', and as the rotary disk 13 rotates in the direction of the arrow shown in FIG.
is engaged with. Further, the other end of the connecting arm 3 is fixed to the actuating body 4. A spring seat 19 is fixed to the actuating body 4, and the actuating body 4
A spring 17 and a spring 18 are arranged in series via a spring intermediate seat 20 that is slidably supported by the spring 17 and the spring 18. Therefore, as the rotating disk 13 rotates, the roller 14 or 1C engages the hook portion 3'', so that the actuating body 4 is activated by the springs 17 and 1.
8 while compressing it and moving it backwards (towards the right in Figures 1 and 2). When the roller 14 or 1C disengages from the hook 3'' of the connecting arm 3, the springs 17 and 18 rapidly expand, and the actuating body 4 moves forward (as shown in FIGS. 1 and 2). The plate body 7 and the buffer body 8 slightly protrude from the tip of the space guide 9 as shown in FIG. Furthermore, since the rollers 14 and 1C are rotatably supported by the rotary disk 13, the escape from the hook portion 3'' is performed smoothly. In this way, the actuating body 4 repeatedly reciprocates in accordance with the rotation of the motor 10, thereby causing the space guide 9
The shock absorber 8 repeatedly hits the skin surface that is in contact with the tip of the skin.

The strength of the flicking corresponds to the magnitude of the compressive force when the springs 17 and 18 are compressed to the maximum (in other words, the repulsive force when changing from compression to extension). For example, in the state shown in FIG. 1, that is, when the initial deflection described later is not applied to the springs 17 and 18, the compressive force is applied to the moving distance L of the connecting arm 3 (the moving distance L is (determined by the distance between the roller 14 or 1C and the drive shaft 12). However, as stated at the beginning of this specification, it is desirable to be able to adjust the strength of the flicking. Therefore, in the present invention, the moving distance L of the connecting arm 3 is kept constant (because it is mechanically difficult to make the moving distance L adjustable), and the springs 17 and 18 are given an initial deflection as described below. , the initial deflection is adjustable to adjust the strength of the flicking. That is, the above-mentioned initial deflection is adjusted by rotating the spring strength adjustment knob 21. The above-mentioned initial deflection adjustment mechanism according to the present invention will be explained with reference to FIG. 3. In FIG. 3, by rotating the spring strength adjustment knob 21 (not shown), a spring strength adjustment screw 27 fixed to the gear 26 via the adjustment knob shaft 22 and gears 23 to 26 is rotated.

When the spring strength adjustment screw 27 is rotated, the spring pressing portion 2 is provided with a threaded portion that engages with the adjustment screw 27.
8 presses the spring 18 (leftward as viewed in FIG. 3). The gears 23 to 26 amplify the rotation angle of the adjustment knob shaft 22 and transmit it to the spring strength adjustment screw 27. In this way, when the spring pressing portion 28 is moved and the spring 18 is pressed, the spring 17 is also pressed because the spring intermediate seat 20 is slidably supported by the actuating body 4. That is, by adjusting the moving distance of the spring pressing portion 28, the springs 17 and 18 are given an initial deflection as referred to in the present invention. The strength of the flipping in the present invention described above is determined by the overall spring constant k of the springs 17 and 18 (the repulsive force generated per unit compression distance of the spring), the initial deflection amount, and the movement of the connecting arm 3 described above. Since it is determined by the distance L, the above-mentioned initial deflection amount, that is, the moving distance of the above-mentioned spring pressing part 28 can be adjusted, and the above-mentioned overall spring constant k and the moving distance L of the above-mentioned connecting arm 3 are appropriately selected. Therefore, it is possible to adjust the strength to a desired level. Note that the above-mentioned overall spring constant k is determined by the following equation. That is, (where, k1 is the spring constant of the spring 17, and K2 is the spring constant of the spring 18.) As explained above, the strength of the so-called flicking in the massager of the present invention is determined by
The moving distance L and the overall spring constant k, that is, the spring 17
By appropriately selecting the spring constants Kl and k2 of 18 and adjusting the above-mentioned initial deflection, it is possible to adjust it to a desired range.

The correlation between the moving distance L1, the spring constants K, kl, k2, and the initial deflection in the embodiment shown in FIGS. 1 to 3 will be explained in more detail when the strength of the flicking is set within a desired adjustment range. . For example, in order to adjust the strength of the repelling to a desired range, the adjustable range of the total compressive force (in other words, repulsive force) of the springs 17 and 18 should be approximately 1.2k9 to 5k9. Make it good. That is, the lower limit of the compressive force is
This value is determined by the travel distance L and the overall spring constant k when the initial deflection is set to zero. Now, the moving distance L is 2'', the spring constant k1 of the spring 17
1.5k9/Wm and the spring constant K2 of spring 18
Assuming that 1.0k9/m, the overall spring constant k is 0.06kg
/m, the spring compression force in this case is represented by the dashed line A in FIG. That is, the above compressive force is 1.2 when the initial deflection is zero.
kg (point a in the figure), and in order to make the compression force 5k9, the initial deflection is about 60.3 m. Therefore, by adjusting the initial deflection from zero to 60.3 m, it is possible to adjust the compressive force to a desired range of approximately 1.2 to 5k9. However, enlarging the adjustment range of the initial deflection is not preferable because it not only increases the size of the initial deflection adjustment mechanism of the present invention shown in FIG. 3, but also increases the rotation angle of the spring strength adjustment knob 21.

Therefore, the adjustment range of the above initial deflection is adjusted from zero to approximately 3i.
In order to make the maximum compressive force about 5k9, it is necessary to use a spring whose overall spring constant k is 0.1k9/number. However, as shown by the two-dot chain line B in Figure 4, the compressive force in this case is the lower limit of the compressive force, that is, the compressive force when the initial deflection is set to zero, which is 2k9, which is a preferable result. I can't get it. In the present invention, when the total deflection of the springs 17 and 18 reaches a predetermined value, one of the springs 17 and 18 is turned off. It is configured to prevent further compression.

Therefore, until the total deflection of the springs 17 and 18 reaches a predetermined value, a compressive force is obtained based on the overall spring constant of the springs 17 and 18, and after that, the spring constant of the other spring alone is obtained. A compressive force based on this can be obtained. This will be specifically explained in connection with the embodiment of the invention illustrated in FIGS. 1-3. That is, in the embodiment shown in FIGS. 1 to 3, the tip of the spring pressing portion 28 presses the spring intermediate seat 20 when the total deflection reaches a predetermined value. That is, even if the total deflection exceeds the predetermined value, the spring 18 is configured not to be compressed any further. In the embodiment illustrated in FIGS. 1 to 3, for example, the connecting arm 3
The moving distance L is 2CM1 The spring constant k1 of the spring 17
1.5k9/? Further, the spring constant K2 of the spring 18 is set to 1.0k9/111j. Assuming that the overall spring constant k is 0.0
6k9/1a, and when the initial deflection is zero and the distance between the tip of the spring pressing part 28 and the spring intermediate seat 20 is 16 m, the initial deflection and compressive force are This relationship is represented by a solid line C connecting points a, b, and c in Figure 3. In other words, by adjusting the initial deflection to a range of 0 to 307 m, the compressive force can be reduced. Almost the desired 1.2k9
It can be adjusted from 5kg to 5kg. Note that the distance L1 of movement of the connecting arm determines whether the desired range of compressive force can be obtained by increasing the distance between the tip of the spring pressing portion 28 and the spring intermediate seat 20 when the initial deflection is zero. This is determined by the spring constant k1 of the spring 17 and the spring constant K2 of the spring 18. Further, in the range from point b to point c in the solid line C shown in FIG. 28 will collide with the tip. The shock at the time of the collision can be alleviated by providing the buffer ring 6.
As explained above, according to the present invention, the elasticity of the spring is utilized and the spring is configured to be deflected in advance, and by adjusting the deflection, the strength of the repelling strike against the skin surface can be easily adjusted. It is possible to provide a massager that can be changed.

In addition, by using two springs in series and configuring so that one of the two springs does not deflect by more than a predetermined distance during the adjustment, the initial deflection can be reduced. It is possible to provide a massager that can reduce the adjustment range and increase the adjustment range of the flicking strength.
