Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pine surger that vibrates and is pressed against an affected area.

[Conventional technology and problems]

Conventionally, this type of pine surge device is known in which an arm having a vibrating part that is pressed against the affected area is connected to a handle by a hinge, and a switch is actuated by relative rotational displacement between the arm and the handle, causing the vibrating part to vibrate. ing. That is, when using this pine surger, when the vibrating part is pressed against the affected area, the arm is rotated and displaced relative to the handle, thereby turning on the switch. However, with this conventional pine surge device, the vibration of the vibrating part is transmitted to the handle, which weakens the vibration force applied to the affected area, which not only prevents the pine surge effect from being fully exerted, but also because the handle vibrates. There is a problem in that the hand holding the device feels uncomfortable.

In order to solve the above problems, the pine surge device according to the present invention includes a casing that is integrally molded from a power source and a flexible material, and has a vibrating part and a main body that are pressed against the affected area, and a casing that is connected to the main body. The casing includes a handle that is configured to vibrate, a vibration source that is housed in the vibrating section and driven by being supplied with power from the power source, and a switch mechanism that electrically connects the power source and the vibration source. The switch mechanism is formed to be elastically deformed at the connecting portion between the vibrating portion and the main body, and the switch mechanism is provided in the connecting portion, and is electrically conductive when the vibrating portion is deflected by a predetermined amount or more with respect to the main body. It is said that

〔Example〕

The present invention will be explained below with reference to illustrated embodiments.

1 to 4 show an embodiment of the present invention. In FIG. 1, a casing 11 and a handle 12 are made of, for example, polypropylene, and the casing 11 has a vibrating section 13 and a main body section 14. Inside the vibrating part 13, a motor 15 is installed.
A switch mechanism 40 is provided inside the main body 14, and a handle 1 is provided inside the main body 14.
A dry battery 16 is housed in each of the batteries 2 . motor 15
An unbalanced portion jF118 that is eccentric with respect to the shaft center is attached to the output shaft 17 of. The motor 15 is connected to switch R.
When the structure 40 is in the ONN state, it is driven by being supplied with power from the dry battery 16, whereby the unbalanced weight 18 rotates and the vibrating part 13 of the casing 11 vibrates.

The casing 11 and the handle 12 each have a cylindrical shape with a bottom,
They are connected to each other by screwing a female thread formed on the inner peripheral surface of the opening 12a of the handle 12 to a male thread formed on the outer peripheral surface of the opening 11a of the casing 11. A stepped portion 1 formed on the outer periphery of the base of the opening 11a of the casing 11
An O-ring 21 is inserted between 1b and the end surface of the opening 12g of the handle 12, thereby sealing off the inside and outside of the casing 11 and the handle 12 in a watertight manner. The casing 11 and handle 12 combined in this manner are covered by first and second covers 22 and 23 each having a cylindrical shape with a bottom and made of a flexible material such as polyvinyl chloride. The first cover 22 closely fits and covers the casing 11, and the opening 22g of this cover is the casing opening 11.
It extends to the step part flb of a. On the other hand, the second cover 23 closely fits and covers the handle 12, and the opening 23 of this cover
a extends beyond the handle opening 12m to the outer circumferential surface of the opening 22m of the first cover 22, and is tightly fitted to this outer circumferential surface. Therefore, the inside and outside of these covers 22 and 23 are sealed off in a watertight manner, thereby ensuring that the insides of the casing 11 and handle 12 are protected from the outside in a watertight manner.

The motor 15 has a pair of ribs 13 formed inside the vibrating section 13.
a, 13b, and the output shaft 17 extends toward the bottom 11c of the casing 11. Protrusions 1gc projecting outward are formed on the vibrating portion 13, and protrusions 22b are formed on the first cover 22 in correspondence to these protrusions 13c. Portions of these protrusions 13c and 22b are pressed against the affected area, and vibrations generated by the weight 18 are transmitted to the affected area via the protrusions.

Two dry batteries 16 are housed in the handle 12 and connected in series.The negative electrode of the dry battery 16 located at the bottom in the figure is connected to the handle 1.
The positive electrode of the dry battery 16 located above contacts the contact fitting 25 provided at the base of the opening 11a of the casing 11. The spring 24 is a band-shaped conductive member 2 provided along the inner wall of the handle 12.
The upper end 26b of the conductive member 26 is engaged with a hole 12b formed in the base of the opening 12g of the handle 12. A conductive member 27 is provided on the inner wall surface of the opening 11a of the casing 11. The lower end 27a of the conductive member 27 is formed into an annular shape and is engaged with the edge of the opening 11a to contact the upper end 26b of the conductive member 26 of the handle 12. Extends to. The lead wire 28 connects the motor 15 to the conductive member 27.
The upper end 27b of the battery 16 is electrically connected to the negative electrode of the dry battery 16. On the other hand, the lead wires 29 and 30 electrically connect the motor 15 to the contact fitting 25, that is, the positive electrode of the dry battery 16 via the switch mechanism 40.

The switch mechanism 40 is provided at the connecting portion 31 between the vibrating section 13 and the main body section 14 . The connecting portion 31 is thinner than the other portions, is bent and protrudes inward from the casing 11, has an opening 31c formed at the bottom, and extends over the entire width of the casing 11. Although the casing 11 is integrally molded from a flexible material, only the connecting portion 31 is substantially flexible. Therefore, when the vibration section 13 vibrates due to the rotation of the motor 15, this vibration is absorbed by the connection section 31 and is not transmitted to the main body section 14. In addition, reinforcing ribs 1 are provided on the inner wall surface of the main body 14.
4b and struts 14c are provided to prevent the main body 14 itself from bending.

2 to 4 show the structure of the switch mechanism 40.
The contact metal fitting 41 is connected to the lead wire 29 on the motor 15 side, and the second contact metal fitting 42 is connected to the lead wire 30 connected to the contact metal fitting 25 on the dry battery 16 side. Second contact fitting 42
is a mounting portion 42a fixed to the inner wall surface 14a of the main body portion 14;
and a contact portion 42b that comes into contact with the outer surface 31a of the connecting portion 31.
and has. The first contact fitting 41 is attached to a U-shaped mounting member 43 that is held between the connecting portion 31 and a protrusion 31b provided close to the connecting portion 31, and is electrically connected to the contact portion 42b of the second contact fitting 42. It has a contact portion 41a that can be contacted.

When the vibrating part 13 is not pressed against the affected area of the user of this pine surge device, the connecting part 31 is in the state shown, and the contact parts 41a, 42 of the first and second contact fittings 41, 42
b challenge each other, so switch nti40 is OF
In state F, the motor 15 is stationary. On the other hand, when the protrusion 22b side of the vibrating part 13 is pressed against the affected area,
The connecting portion 31 is elastically deformed in the direction in which the opening 31c is enlarged, whereby the second contact fitting 42 is displaced to the right in the figure, and the first and second contact portions 41a and 42b are brought into electrical contact. As a result, the motor 15 rotates and the vibrating section 13 vibrates. Next, when the vibrating part 13 is released from the affected area, the connecting part 31 narrows the opening 31c and restores to the state shown in the figure, and the contact parts 41a and 42b are brought back to N1 and the motor 15 stops.

As described above, in this embodiment, the vibrating part 13 is formed to be elastically deformed at the connection part 31 with respect to the main body part 14, and when the vibrating part 13 is bent by a predetermined amount or more with respect to the main body part 14, the switch machine 140 is configured to be electrically conductive. Therefore, switch Rt7A40 is 0
Not only is the N-OFF operation reliable, but the structure is simple and inexpensive. Also, substantially the connecting portion 31
Since only the connecting portion 31 is elastically bent and the other portions are hardly bent, the vibration of the vibrating portion 13 is absorbed in the connecting portion 31 and is hardly transmitted to the main body portion 14 .

Therefore, most of the vibration of the vibrating part 13 is transmitted to the affected area,
The original effect of the pine surger can be fully exhibited, and since the vibration of the handle 12 is small, the handle 12 can be easily held. Further, since the casing 11 and the handle 12 are assembled in a watertight manner and isolated from the outside, this pine surge device can be used in a place with a lot of moisture, such as a bathroom.

〔Effect of the invention〕

As described above, according to the present invention, the vibration of the vibrating part becomes sufficiently large to increase the pine surge effect, and the vibration of the handle is reduced, making handling easier.
