Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a pine surge device, in particular, a device that applies reciprocating motion repeatedly to a plurality of attachments in order to repeatedly press the skin surface using the elasticity of a spring. This is about the pine surge device I have.

[Problems to be solved by conventional technology and invention]

BACKGROUND ART Pine surge devices have been known for beauty and health purposes, which stimulate the skin and muscles by repeatedly tapping the skin surface.

Conventional pine surge devices have one attachment that repeatedly flicks the skin surface, and are configured to drive this one attachment back and forth to release the energy stored in an elastic body such as a spring all at once. . Therefore, unless the pine surge device is moved, the pine surge position is fixed and pine surge is performed continuously at one location. There was also a limit to the shortening of the cycle of flicking the skin surface.

Therefore, in order to solve the above-mentioned problems, it is considered to provide a plurality of the above-mentioned attachments, but according to the conventional method, each attachment requires an independent drive unit. , an undesirable problem arises in that the pine surge device becomes larger.

In addition, since conventional pine surgery devices release the energy stored in an elastic body such as a spring all at once, when performing pine surgery on an area with a thin subcutaneous muscle layer, such as the head, it may be necessary to Finally, there was an undesirable problem in that the force of the above-mentioned flicking was too strong.

The present invention aims to solve the above-mentioned problems by providing a plurality of attachments and configuring the plurality of attachments to be driven by one drive unit, thereby widening the pine surge range and The object of the present invention is to provide a compact hand-held pine surger that enables so-called soft pine surgery on the skin surface.

[Means to solve the problem]

An attachment that presses the skin surface, a drive unit that reciprocates the attachment, an energy storage means consisting of a spring elastic body that stores energy by being pressed when the attachment is driven, and a reciprocating range of the attachment. In the massaging device, the energy storage means is configured to store energy when the attachment is driven backward and to release energy when the attachment is driven backward, and the energy storage means is configured to store energy when the attachment is driven backward. In addition, each of the plurality of attachments is provided with the independent energy storage means, and is engaged with each of the plurality of attachments and changes the position in the reciprocating direction of the plurality of attachments to a rotational angular position. A rotary cam is provided whose thickness in the reciprocating direction changes in accordance with the rotational angular position, and the rotary cam is rotated by the drive unit so as to It is characterized by being configured to sequentially drive a plurality of attachments.

This will be explained below with reference to the drawings.

Each becomes uniform.

The basic configuration and operation of the embodiment shown in FIG. 1 have been explained above.
Attachments 3-1 to 3 above in connection with the figure
-3 driving operation will be specifically explained.

In FIGS. 2 and 3, the attachment 3-1 includes an attachment shaft 3-1a,
a lift arm 3-1b fixed to the attachment shaft 3-1a and engaged with the cylindrical rotating cam 7;
Attachment connecting portion 3-1c, pressing portion 3-1d, and pressing portion 3 fixed to −1a by, for example, a magnet or a screw (not shown).
-1d is detachably attached to the attachment buffer section 3-1e and connected to the attachment coupling section 3-1c via, for example, a spring or a buffer material (not shown). and,
The attachment 3-1 is an attachment
A spring 8-1 is inserted through the shaft 3-1a and has one end locked to the spring fixing pin 9-1.
At the same time, it is installed so as to pass through a spring accommodating portion 6-10 provided in a portion of the drive unit housing 6-11. The attachment 3-1 has been described above, but the other attachments 3-2 and 3-3 are also configured in the same manner as the attachment 3-1, and the attachments 3-1 to 3-3 have their shafts centered They are arranged so as to be located on concentric circles. The rotation stop pins 3-1f, . . . shown in FIG. 3 are means for preventing rotation of the attachments 3-1 to 3-3.

The above lift arm 3-1b or 3-3b
is slidably engaged with the end face of a cylindrical rotary cam 7 which is fixed to and rotates on a main shaft 6-1 which is an output shaft of a drive unit 6 which will be described later with reference to FIG. Then, the cylindrical rotating cam 7
As shown in FIG. 4, the end face is formed to have steeply inclined surfaces A, A' and gently inclined surfaces B, B'. Note that FIG. 4 shows the cylindrical rotary cam 7 and the lift arm 3-3 in order to explain the operations of the attachments 3-1 to 3-3.
It is a 360 degree development view showing the relative position with 1b or 3-3b.

As the cylindrical rotary cam 7 rotates,
The lift arms 3-1b to 3-3b are
It moves while sliding on the end face of the cylindrical rotary cam 7. The direction of rotation of the cylindrical rotary cam 7 is as follows:
The direction in which the lift arms 3-1b to 3-3b move is from gently sloped surface B (or B') to apex P (or P') to steeply sloped surface A (or A'), that is, as shown in FIG. In FIG. 4, the direction is counterclockwise, and in FIG. 4, the direction is the direction indicated by the arrow R.

For example, if the lift arm 3-1b is on a gentle slope B
While moving above and reaching the apex P, the attachment shaft 3-1a (see FIG. 3) retreats and the spring 8-1 is compressed. When the attachment shaft 3-1a moves beyond the apex P and moves on the steeply sloped surface A, the repulsive force of the spring 8-1 causes the attachment shaft 3-1a to move forward rapidly and the pressing part 3-1d -Protrudes from the spacer 2 and presses the skin surface with the pressing portion 3-1d. The strength of the pressing increases as the inclination angle of the steeply inclined surface A increases and as the rotational speed of the cylindrical rotary cam 7 increases. In addition,
The arrow a shown in FIG. 4 indicates the stroke of the attachment shaft 3-1a when performing pine surgery, that is, when the attachment spacer 2 is in contact with the skin surface, and the arrow b shown in FIG.
indicates the free stroke of the attachment shaft 3-1a. Note that, for example, if the slope angle of the steeply sloped surface A is 90° (vertical), the spring 8-1 is instantly released when the lift arm 3-1b exceeds the apex P. , a high-pitched mechanical sound is generated. and,
I feel uncomfortable because the mechanical sound occurs continuously and repeatedly. However, in the present invention, by forming a steeply sloped surface A in a portion beyond the apex P, the rebound of the spring 8-1 after the lift arm 3-1b passes the apex P is reduced. The condition is moderate, so to speak, restricted by the steep slope A, and unpleasant mechanical noise is prevented from occurring.

Although the operation of attachment 3-1 has been described above, the operations of attachments 3-2 and 3-3 are also similar. Therefore, as shown in Figures 1 to 4, the number of attachments is 3.
When the number of vertices of the cylindrical rotating cam 7 is two, the number of repetitions of pressing against the skin surface is six times for each rotation of the cylindrical rotating cam 7. That is, the pressing portions 3-1d to 3-3d
The skin surface at the position corresponding to is pressed six times in sequence. Although the embodiments shown in FIGS. 1 to 4 are pine surgers in which the number of attachments is three and the number of vertices of the cylindrical rotating cam 7 is two, the present invention is not limited to this. Instead, the number of attachments may be two or more than four, and the number of vertices may be one or more than three. Furthermore, although the pressing parts 3-1d to 3-3d in the embodiments shown in FIGS. It is also possible to use a material formed in other shapes such as a shape.

Next, an embodiment of the drive unit 6 for driving the cylindrical rotary cam 7 will be described with reference to FIG.

In FIG. 5, a main shaft 6-1 that drives the cylindrical rotary cam 7 (not shown) is fitted and fixed into a first gear shaft 6-2. Main gear 6
-3 is inserted and fixed. The second gear shaft 6-4 includes the main gear 6-4.
A first pinion gear 6-5 and a crown gear 6-6 that mesh with the first pinion gear 3 are respectively fitted and fixed. Further, a motor 6-7 is fixed to the drive unit housing 6-11, and a second pinion gear 6-9 fitted and fixed to the motor shaft 6-8 of the motor 6-7 is connected to the crown gear 6. −
It is configured to mesh with 6. Therefore, by driving the motor 6-7, the motor
shaft 6-8, second pinion gear 6-9,
Crown gear 6-6, first pinion gear 6
-5, the cylindrical rotating cam 7 is driven via the main gear 6-3, the first gear shaft 6-2, and the main shaft 6-1. In addition,
The spring housing portion 6-10 corresponds to the spring housing portion 6-10 illustrated in FIG.
