Description

[Detailed Description of the Invention] Technical Field 1 The present invention relates to a massager:) An eccentric or inclined inner ring portion is provided on a drive shaft that is rotationally driven around a rock, especially an axis, and
This invention relates to a pine surge machine that performs pine surge by the operation of a freely rotating member attached to the outer periphery of an inner ring portion.

1 Back Weight Technology] As shown in FIG. 7, an inner ring portion 2 that is eccentric or inclined with respect to the drive shaft 1 and an idling member 3 provided on the outer periphery of the inner ring portion 2 to allow free rotation are provided. For example, a pine surge machine that performs pine surge by the movement of a member () is one in which a kneading ring is made up of an inner ring part 2 and an idling member 3.
This is known from, for example, Japanese Patent No.-22528. However, this kneading wheel used as a member for pine surge has the following problems. In other words, although a pair of kneading wheels are normally provided at intervals on the drive shaft 1, when trying to massage the side of the face or the first side of the eyebrows, the kneading wheels shown in Fig. 8 and ! As shown in Figure J, the drive shaft 1 between the two massaging wheels is at the rear of 1"1", and the drive shaft 1 gets in the way, making it impossible to obtain a No. 1 72 thread. First, if you increase the outer diameter of the kneading wheel to avoid this problem, the radius of curvature of the outer circumferential surface of the kneading wheel will increase.
The area of contact with the body becomes larger, making it impossible to obtain the so-called point pine surge that presses the ``pressure points''.

[Objective of the Invention 1 The present invention has been made in view of the above points, and its purpose is to provide a pine serge machine that can perform good point pine surge on a pair of front surfaces, upper surfaces of shoulders, etc. It is on offer.

[Disclosure of the Invention 1] The present invention provides a drive shaft that is rotatably driven around an axis, an inner ring portion that is provided eccentrically or inclined to the drive shaft, and a drive shaft that is rotatably attached to the outer periphery of the inner ring portion. The projecting member includes a free rotating member, a protruding member and a connecting member that both protrude in the radial direction from the free rotating member, and a protruding member provided with a treatment element at the distal end, and a free rotating member that is connected to the support member. The key point is that one of the connecting members that regulates the rotation of the member is formed of a spring material, and instead of performing pine surgery directly with the free rotating member, it is possible to perform massage using a treatment element protruding from the free rotating member. 77 sano is performed, and the operation of this treatment element is characterized in that it does not apply unreasonable force to the body due to the elasticity of the spring material.

The present invention will be described in detail below based on the illustrated embodiment.A pair of opposing support plates 1 provided on a U-shaped frame 10
2.12 A drive shaft 1 and a feed screw 11 are installed in parallel, and one end of the drive shaft 1 is connected to a motor 15 with a deceleration W11.
6. Further, one end of the feed screw 11 meshes with a gear 17 attached to the drive shaft 16 via a clutch 19 and a gear 18.

A pair of inner ring portions 2, 2 are attached to the drive shaft 1. Both inner ring portions 2, 2 are composed of an eccentric disk 21 that is both eccentric and inclined with respect to the drive shaft 1, and a cylindrical shaft 22 that is not eccentric. An inner race surface 24 is formed on the inner race surface 24. In addition, these inner ring portions 2.2 are movable in the axial direction of the drive shaft 1 with a key 14 and rotate together with the drive shaft 1, and furthermore, the inner ring portions 2.2 are arranged so that the inner ring portions 2.2 are Although the eccentric directions of the disks 21 and 21 are the same, the inclination directions are opposite.

An idling member 3 whose inner circumferential surface is a race surface 30 is attached to the outer periphery of the eccentric disc 21 of the inner ring portion 2 via a large number of balls 28 held by a retainer 27. ing. This free rotating member 3 includes an arm 31 that projects in the radial direction, and a connecting arm 32 that also projects in the radial direction and whose projecting direction is opposite to that of the arm 31.
A roller 4 as a treatment element is attached to the tip of the arm 31.

In the figure, reference numeral 40 denotes a bearing that is press-fitted into the roller 4 and receives a roller shaft 41 attached to the tip of the arm 31.

One end of a coil spring 5 is fixed to the front end of the other connecting arm 31 with a stopper 50 . The other end of this coil spring 5 is attached to a support 8 by a stopper 50.
Furthermore, the support body 8 is attached to the *1!11 arm 7 by an adjustment screw 80 that is screwed into a screw hole 85 of the support body 8. The adjustment arm 7 has a shaft hole 71 at one end fitted into the outer periphery of the cylindrical shaft 22 of the inner ring portion 2 so as to freely rotate, and a threaded hole 72 at the other end screwed into the feed screw 11. It has a shaft hole 73 that rotatably supports one end of the adjusting screw 80, and an id rip 70 that slidably engages with a groove 80 on one end surface of the support body 8.

When the handle 81 fixed to the other end of the adjustment screw 80 is rotated, the support body 8 is moved along the axial direction of the adjustment screw 80.
Move while receiving the id of Idlib 70. Also, each l
The lI adjustment arms 7.7 are each screwed into the feed screw 11 as described above, and the portion of the feed screw 11 where one adjustment arm 7 is screwed into is screwed into the other adjustment arm 7. The screws are opposite to the other parts. In Fig. 2, 26 is a C-shaped ring for preventing the adjustment arm 7 from being removed from the inner ring portion 2, and 88 is an adjustment screw 8 for the sq arm 7.
This is an E-shaped ring for the first toe of 0.

In addition, 13 in the figure is an elongated hole provided in 7 and 10 to allow the handle 81 at one end of the adjustment screw 80 to protrude to the outside.
9 is an outer cloth that covers the heat treatment member, and this outer cloth 9 is attached to the 7 frame 10 with rivets so as not to interfere with the operation of the rollers 4, 4 as treatment elements. ing.

This pine surge machine, which has a rectangular shape as shown in Fig. 31ffi+2, has a chair-f
It is attached to the backrest portion of the human body 91 together with a plurality of rectangular cushions 90, and by replacing the cushions 90, the position of the backrest can be changed.

However, in this lever pine serge machine, when the drive shaft 1 is rotated around its axis by rotating the motor 15, an idling wheel disposed freely around the outer periphery of the eccentric disk 21 that rotates together with the drive shaft 1 rotates. The member 2 has an eccentric disk 21 that is eccentric and inclined, and rotation around the eccentric disk 21 is restricted by the connecting arm 32, coil spring 5, and support 7, so that the treatment element The roller 4 periodically moves in three directions: the Z direction, which is the protruding direction of the arm 31, the X direction, which is the axial direction of the drive shaft 1, and the Y direction, which intersects both of these X4 directions. That is, while slightly changing the position of the connecting point between the connecting arm 32 and the coil spring 5, the eccentric component of the eccentric disk 21 causes the roller 4 to move in the YZllTIIJj direction, and the tilt component of the eccentric disk 21 causes the roller 4 to move in the YZllTIIJj direction. , the roller 4 is made to move in the X direction, and when a body touches the roller 4 at the height, the roller 4 moves according to the reaction force from the body.
Instead of moving in one direction, it performs movements in two other directions. In other words, due to the presence of the coil spring 5, the roller 4 will not push the body with more than a certain force, and will not place an unreasonable load on the body.

Furthermore, when the support body 8 is moved by rotating the handle 81, the X direction/\ and protrusion of the roller 4 changes, so the strength of the pine surge can be adjusted. By connecting motor 15
When the rotation of is transmitted to the feed screw 80, both i11! Since the screw directions of both the threaded portions of the adjustment arm 7.7 and the feed screw 11 are opposite, the inner ring portions 2, 2 move in opposite directions in the axial direction of the drive shaft 1. , therefore 1
Here, the distance between both rollers 4, 4 is adjusted. The distance between the rollers 4, 4 can be set according to the treatment area, and at the same time, the strength of the pine surge can also be adjusted.

Another embodiment is shown in Figure vJ6. Here, a long hole 33 is provided in the connecting arm 32 that protrudes from the free rotation member 3, and by engaging the bin 75 that protrudes from the V4 adjustment arm 7 with the long hole 33, the rotation of the free rotation member 3 is restricted. The arm 31 for attaching the roller 4 is formed of a coil spring 5.

In the figure, reference numeral 35 denotes a mounting base for attaching the roller 4 to the tip of the coil spring 5, which is 31. In this case as well, the roller 4 moves in three directions, XYZ, as in the previous embodiment, and the pine surge load on the human body is unreasonable due to the presence of the coil spring 5. It is something that never happens.

In the above embodiment, the inner ring portion 2 is eccentric and inclined with respect to the drive shaft 1, but it may be eccentric only or inclined only.

[Effect of the invention 1 As described above, in the present invention, since the treatment element is provided at the tip of the protruding member that protrudes from the free rotation member, the drive shaft does not get in the way when pine surges are applied to the side of the neck or the upper surface of the wing. It is possible to sufficiently perform point pine surgery without causing irritation, and the massager moves in a manner similar to that of conventional massage wheels, making it extremely effective for pine surgery. However, the presence of the spring member prevents the operation of the treatment element from placing an unreasonable load on the human body, making it safe and painless.
