Description

[Detailed description of the invention] This invention relates to a massaging device.

Conventionally, as a massager, for example, a shoulder tatcher, a contacting body is attached to the tip of a plunger inserted through an intermittently excited electromagnet, and the intermittent reciprocating movement of the plunger causes the said contacting body to be pressed against the shoulder. There are also products available that allow you to hit the ball with something like this. However, this method has the disadvantage that a sufficient pine surge effect cannot be obtained because the abutting body is simply struck from a substantially perpendicular direction to the surface to be pine surged.

This invention was made based on the above circumstances, and its purpose is to provide a massaging device that can perform effective pine surge by adding a kneading action to the area to be pine surgged, in addition to simply hitting the area to be pine surgged. be.

The present invention will be described below based on an illustrated embodiment. In the figure, reference numeral 1 denotes a casing constituting the massager body, and the casing 1 is formed in a size and shape that can be held by hand. A drive unit 2 is attached to one end of the casing 1. The drive unit 2 will be described in detail below. In the figure, 3 is an iron frame with openings on both the upper and lower sides, and a rotor 5 that can freely rotate around a pivot portion 4 is pivotally attached to this frame 3. ing. The rotator 5 has a substantially U-shaped side surface and a leg portion 5 located on one free end side of the rotator 5.
a, and attracted parts 5c, 5c located on the other free end side of the rotator 5 and made of a magnetic material such as iron. These attracted parts 5c, 5c
extend in opposite directions along both rotational directions of the rotator 5, respectively. Reference numeral 6 denotes a cushioning material made of rubber or the like attached to the rotator 5. Further, the leg portion 5a is provided with a pair of abutting bodies 7, 7 that abut against a portion to be pine surged, such as a shoulder. These abutting bodies 7, 7 are made of synthetic resin or a material having appropriate elasticity, and are arranged in the direction of rotation of the rotator 5.

Further, as shown in FIG. 2, the pivot portion 4 has a pivot 9 fixed to the frame 3 with screws 8, 8, and an oil-impregnated bearing 10 press-fitted into the rotor 5.
The pivot shaft 9 is rotatably inserted into the shaft.

Further, a pair of electromagnets 11, 11 for driving the rotor 5 are fixed to the frame 3.
The electromagnets 11, 11 are respectively arranged at the front and rear of the rotor 5 in its rotation direction. Each electromagnet 11, 11 has a coil 12 and a fixed core 1, respectively.
3, yoke 14, etc., and the coil 1
The suction target portion 5c is inserted into the insertion hole 12a of No.2. The electromagnets 11, 11 are intermittently and alternately energized, for example, several times per second, by a drive circuit 15 built into the casing 1, thereby causing the rotor 5 to rotate back and forth. It's becoming like that. Reference numerals 16 and 16 are cushioning materials, and these cushioning materials 16 and 16 also serve as stoppers for regulating the rotation range of the rotator 5.

In the massaging device configured as described above, when a power switch (not shown) is turned on and power is supplied to the drive circuit 15, the electromagnets 11, 11 are alternately excited, and the attracted parts 5c, 5c are alternately strongly and rapidly attracted. For,
The rotator 5 intermittently rotates back and forth about the pivot portion 4 . Therefore, since the abutting bodies 7, 7 also reciprocate, the part A to be pine surged, such as a shoulder, is sandwiched between these abutting bodies 7, 7, and the pine surge is performed by the abutting bodies 7, 7. At this time, the abutting bodies 7, 7 alternately strike the pine surge area A from different diagonal directions while sandwiching the pine surge area A, so it is not necessary to simply hit the pine surge area from the vertical direction like a conventional shoulder tapper. By adding a kneading motion, you can create an effective pine surge.

Further, since the rotor 5 is rotated alternately by the two electromagnets 12, 12, the rotor 5 can be rotated back and forth with a large driving force, and the rotor 5 can be rotated in both rotation directions. Each has the advantage of being able to rotate with equal force.

Although two abutting bodies were used in this embodiment, the intended purpose of the present invention can be achieved even with one abutting body. The number, shape, and other aspects are not limited to the embodiments.

As explained above, this invention provides an abutting body on one free end side of a rotator that is rotatably supported around a pivot, and a suction target part on the other free end side. The attracted parts are alternately attracted by electromagnets that are alternately excited, thereby causing the abutting body to rotate back and forth. Therefore, according to the present invention, the abutting body does not simply hit the pine surge part from the vertical direction, but adds a kneading operation from an oblique direction using rotational force to perform the pine surge, thereby achieving effective pine surge. can be done. Moreover, since the rotator is alternately attracted and driven by electromagnets and rotates back and forth, a large driving force can be obtained, and if the same electromagnet is used for each attracted part, it can be rotated alternately in both rotation directions. It has various excellent effects such as being able to rotate reciprocatingly with uniform force and making the reciprocating rotational force uniform.
