Description

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

Conventional massaging devices include, for example, a shoulder pat device in which a contacting body is attached to the tip of a plunger inserted into an intermittently excited electromagnet, and the said contacting body is struck against the shoulder by the intermittent reciprocating motion of the plunger. is provided.

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 pine surge target portion.

This invention was made based on the above circumstances, and its purpose is to easily perform effective pine surge by adding kneading and grasping motions to the area to be pine surgged, rather than simply hitting the area to be pine surgged. Our aim is to provide an easy massaging device.

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.

The drive unit 2 will be described in detail below. In the figure, 3 is an iron frame with both upper and lower sides open, and a rotor 5 that can freely rotate around a pivot 4 is pivotally attached to this frame 3. ing.

The rotor 5 has a substantially U-shaped side surface and has a leg portion 5a located on one free end side of the rotor 5, and a leg portion 5a located on the other free end side of the rotor 5 made of iron or the like. The attracting portion 5c is made of a magnetic material.

These attracted portions 5c and 5c extend in opposite directions along both rotation directions of the rotor 5, respectively.

Reference numeral 6 denotes a cushioning material made of rubber or the like attached to the rotator 5.

On the other hand, the leg base [5a is provided with a pair of abutting bodies 7, 7 that abut against a portion to be pine surged, such as the shoulders.

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 rotor 5 with respect to each other.

Further, as shown in FIG. 2, the pivot portion 4 fixes the pivot shaft 9 to the frame 3 with a screw 8.8, and rotatably attaches the pivot shaft 9 to an oil-impregnated bearing 10 press-fitted into the rotor 5. It is inserted.

Further, a pair of electromagnets ii and 1i for driving the rotor 5 are fixed to the frame 3.

Each electromagnet 11.11 is disposed at the front and rear of the rotation direction of the rotor 5, respectively.

Each electromagnet ii, ii has a coil 12 and a fixed core 1, respectively.
3, a yoke 14, etc., and an attracted portion 5c is inserted into the insertion hole 12a of the coil 12.

Then, the electromagnets 1i and ii are intermittently and alternately energized by a drive circuit 15 built in the casing 1, for example, several times per second, so that the rotor 5 is rotated back and forth. Reference numerals 616 and 16 are cushioning materials, and these cushioning materials 16.16 also serve as stoppers for regulating the rotation range of the rotator 5.

In the massager configured as described above, when the power switch (not shown) is turned ON and the drive circuit 15 is energized, the electromagnet i
i and 1i are alternately excited to alternately strongly and rapidly attract the attracted parts 5c and 5c, so the rotator 5 intermittently rotates back and forth about the pivot part 4.

Therefore, since the abutting bodies 7, 7 also reciprocate, the part A to be pine-surged, such as the shoulder, is sandwiched between these abutting bodies 7, 7, and the pine-surging is performed by the abutting bodies 7, 7.

At this time, the contact members 7, 7 sandwich the pine surge portion A, and
Since the hammering motion is performed alternately from different diagonal directions, it does not simply hit the area to be pine surged from the vertical direction like a conventional shoulder tap, but also adds a kneading motion and a grasping motion to achieve effective pine surge. be able to.

Although a pair of electromagnets were used in this example, one
Of course, the rotor may be rotated back and forth using a single electromagnet, and in short, the present invention only requires that a plurality of abutting bodies be arranged in the direction of rotation of the rotor.

As explained above, this invention provides a plurality of abutting bodies along the direction of rotation of a rotor that is intermittently rotated back and forth, so that the pine surge portion is sandwiched between these abutting bodies. Since the part to be pine surged is struck alternately from diagonal directions, effective pine surge can be performed not only by simply hitting the part to be pine surged from the vertical direction, but also by adding kneading and grasping motions.

Since the present invention includes a drive unit configured by attaching a rotor and an electromagnet to the frame,
The majority of the assembly is completed by mounting the drive unit on the casing and is therefore easy to assemble.

Furthermore, since the rotator is rotated by an electromagnet,
The drive unit is small, and therefore the casing to which the drive unit is attached can be of a size and shape that can be held by hand, and is therefore easy to use.
