Description

[Detailed description of the invention] The present invention relates to an improvement of a chair-type pine surge machine, in which a pair of pine surge rollers that move up and down along a rail by forward and reverse rotation of a screw shaft are provided with a second pine surge roller that is softer than the pine surge rollers. A pair of pine surge rollers are rotatably supported, and are normally pushed up by the action of a spring, but when the pine surge roller installed on the outside descends and reaches the membrane part, it is pushed down by the rollers, causing the sacrum. A roller for applying relatively strong acupressure-like stimulation to the area is provided, and a pine surge roller exclusively for the neck, which is provided on the outside above the rail, is pushed up by the inner pine surge roller to apply acupressure-like stimulation to the neck.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. 1 is a main body of a pine surge machine, and inside the backrest part 2 of the main body, there are:
A screw shaft 5 that rotates forward and backward is fixed upright from a reversible motor 3 as shown in FIGS. 2 and 3 via a rotation transmission mechanism 4 consisting of pulleys, belts, etc. Rails 6.6 are attached at predetermined intervals on both sides, and these rails 6.6 are attached to parts of the body corresponding to the eyebrows, between the shoulder blades, the back of the stomach, the lower back, and both sides of the sacrum. Curved protrusions 6a are integrally formed.

In addition, the upper base end of the ring 8.8 is swingably supported by a pin 7.7 on the outside of the upper end of the rail 6.6, and a neck dedicated to the nape of the neck is provided between the lower free ends of the links 8,8. An auxiliary pine surge roller 9 is mounted horizontally.

This roller 9 normally remains stationary as shown in FIGS. 2 and 3 due to its own weight, but when a pine surge roller (to be described later) rises, it is pushed up using the pin 7 as a fulcrum as shown in FIG. The device swings counterclockwise to impart a shiatsu-like pine surge effect to the user's neck.

An upper limit switch 10 and a lower limit switch 11 are attached to one of the rails 6 (the left rail in FIG. 3), and these switches 10 and 11 control the motor 3 in forward and reverse rotation. It has become.

Reference numeral 12 denotes a bracket to be screwed onto the screw shaft 5, and this bracket 12 is held between left and right holding plates t-13 and 14, and these plates 13 and 14 are connected and fixed to each other with screws 15 16 and 17. is the bracket 12
and play) 13. The limit switch 10 is installed on one frame 16 of the lifting frame that goes up and down along with 14.
．． A switching piece 16a for turning on the 11 actuators is integrally formed.

Also, link pins 18 are attached to the lifting frames 16 and 17.
．． 19 is used to pivot the base end of a parallel link 22 consisting of two link plates 20.21, and one end of a spring 23 wound around the outside of the link pin 19.20 is attached to the link plate 21, and the other end is attached to the link plate 21. They are respectively locked to locking pins 24 on the frames 16 and 17.

A switching frame 25 that protrudes and moves in the horizontal direction is provided at the free end of the parallel link 22, and this frame 2
A roller shaft 26 is installed horizontally between both bent portions of the roller 5, and the roller shaft 26 includes the rail 6.6, guide rollers 27, 27, and 27 that roll along the rail 6.6.
Pine surge rollers 28.28 and 2 on the inside and outside of 27.
9.29 is loosely fitted.

A guide roller 27 and a pine surge roller 29 that is softer than the pine surge roller 28 are loosely fitted into the cylindrical portion 28 a of the pine surge roller 28 .
The groove 27a is fitted into the front end of the above-mentioned cross-shaped rail 6.6.

Further, the guide roller 27 is constantly pressed toward the rail 6 by the spring 23.

Reference numeral 30 denotes a support roller shaft horizontally suspended on the lifting frame 16, 17, and an inside support roller 3 is provided at the outer end of the two upper and lower support roller shirts l-30, 30.
1, and an outside support roller 32 is pivotally attached to the outer end of one support roller shaft 30 in the center.

The inside and outside support rollers 31 and 32 sandwich the cross-shaped rail 6 from the front and back.

(See Figure 4) The lower end base of the link 35.35 is pivotally supported by pins 34, 34 on the lower outer side of the rail 6.6, and the shaft 36 is horizontally supported between the upper free ends of the link. Then, a pine surge roller 37.37 dedicated to the sacral region is attached to the outer shaft 36 of the nonch 35.35, and springs 38, 38 are always attached.
When the pine surge rollers 28 and 29 descend, the outer pine surge rollers 29 push the pine surge rollers 37 and 37 upward against the elasticity of the spring 38. 34.3
4 as a fulcrum and is configured to apply acupressure-like pine surge to the sacral region.

The operation of the present invention configured as described above will be explained below.

Now, when the reversible motor 3 is rotated in either the forward or reverse direction, the rotational force is transmitted to the screw shaft 5 through the rotation transmission mechanism 4 consisting of a bell 1-1V boob, etc., and the shaft 5 rotates. do.

A bracket 12 is screwed onto this screw shaft 5, and elevating frames 16 and 17 are connected to the left and right sides of this bracket 12, so that the frames 16 and 17 are parallel to each other.
Then, the pine surge rollers 28, 29, etc. move up and down as the screw shaft rotates.

When the frames 16 and 17 are raised and lowered, the rails 6 are held between the inside support rollers 31 and the outside support rollers 32, and the frames 16 and 17 are raised and lowered in a circular motion.

Also, as the frames 16 and 17 move up and down,
When the guide roller 27 having the curve a reaches the curved protrusion 6a of the rail 6, this guide roller and the pine surge roller 2
8.29 protrudes forward and the rolling pressure of the roller acts strongly locally on a predetermined part of the back of the user, but since the outer roller is a soft one made of soft synthetic resin rubber, etc. It works well on the body.

When the rollers 28 and 29 project forward in this manner, the parallel link 22 swings via the swing foot 25.

In other words, this link 22 resists the spring 23 and
It will swing clockwise in the figure.

Also, as the pine surge roller 28 rises, the roller 2
8 comes into contact with the auxiliary pine surge roller 9 dedicated to the nape of the neck,
This roller 9 rotates counterclockwise, as shown by the dashed line in FIG. 3, about the pin 7 as a fulcrum, thereby imparting an acupressure-like pine surge effect to the nape of the user's neck.

It goes without saying that the pine surge rollers 28 and 29 impart a rolling pine surge effect to the user's back surface in areas other than the protrusion 6a of the rail 6.

The pine surge rollers 28 and 29 are lowered, and the pine surge rollers 29 and 29 are the pine surge rollers 37 and 37.
When in contact with the rollers 37, 37, the pins 34, 34
The pine surge rollers 28 and 29 are rotated clockwise and pushed forward against the springs 38 and 38, as shown by the dashed line in FIG. Gives a shiatsu-like pine surge effect to the lower back area.

When the pine surge rollers 28 and 29 rise, the pine surge roller 37 returns to its original position due to the elastic force of the springs 38 and 38.

The present invention has four pine surge rollers that are rotatably mounted on the same shaft and that move up and down by the forward and reverse rotation of the screw shaft 5, and the pine surge rollers located on the outside are softer than the pine surge rollers located on the inside. roller 2
8 pushes up the pine surge roller 9 dedicated to the neck when it ascends, and the outer pine surge roller 37 pushes down the pine surge roller 37 when it descends to give a shiatsu-like pine surge effect to the sacrum area, and the pine surge rollers 28 and 29 provide two types of hard and soft stimulation. It can provide different types of acupressure and rolling pine surge effects, making the pine surge effect even more effective.
