Description

[Detailed Description of the Invention] The present invention relates to an acupressure machine, and particularly to an acupressure machine with a set of rollers that performs acupressure using transfer of rollers.

The purpose of this invention is to widen the range of acupressure and change body shape (curvature).
To provide a roller set acupressure machine capable of exerting an effective acupressure effect in accordance with the above.

Another object of the present invention is to provide a set of rollers for acupressure, in which the rotating mechanism for moving the rollers is safely constructed by covering it with a cover, and the rollers can be moved smoothly by using this cover. The aim is to provide an opportunity.

Embodiments of the present invention will be described below with reference to the drawings.

That is, the roller set acupressure machine of the present invention operates by moving the rollers in the longitudinal direction on the upper surface of the body shaped like a bed.

Overall, the main body of the shiatsu machine, indicated by a, is a rectangular box with a slightly lower height except near both ends, and a shiatsu roller in the center of the top.
・Sliding groove 1 is split in the longitudinal direction.

Acupressure roller...1 is attached to a support shaft 3 inserted into the support leg 21 of an inverted U-shaped roller moving frame 2 so as to be freely rotatable, and guide rails are provided at both ends of the support shaft 3. A guide roller 11.11 running on 4,4 is installed.

22. 22 is a floating blind hole of the support shaft 3 formed in the support leg 21, and is split vertically.

5 is a screw shaft rotated by a motor M, and is connected to the roller moving frame 2 via a feed nut 51 that moves along the threaded groove of this screw shaft.

Note that it is preferable to use a self-warming synthetic resin or the like for the feed nut 51 to ensure smooth movement.

Reference numeral 6 denotes a cover of the screw shaft 5 which has a hole-shaped side surface, and allows the feed nut 51 to move within the hole-shaped groove.

23...23 is a rocking prevention plate formed at the four corners of the roller moving frame 2, and the guide rollers 24 are mounted in upper and lower stages.The flange 61 formed at the edge of the cover 6 of the screw shaft .61 is held between the top and bottom.

As illustrated in FIG. 1, the guide rails 4, 4 are bent upward near one end to match the curvature of the back.

Further, in the embodiment, an example is shown in which the guide frame 22' is fitted into the floating blind hole 22 installed in the support leg 21 of the roller moving frame, but the present invention is not limited to this.

Reference numeral 7 denotes a cover that covers the upper surface of the shiatsu machine body a, and is made of a synthetic resin sheet or other material having appropriate strength and elasticity.

Although not particularly shown, it is preferable that the rotation of the motor M is automatically switched between normal rotation and reverse rotation by activating a limit switch or the like when the roller moving frame 2 contacts both ends of the main body a.

Since the present invention is configured in a diagonal manner, the screw shaft 5
When the roller moving frame 2 connected and integrated with the feed nut 51 moves with the rotation of the body a, the roller rods 1 protruding from the upper surface of the main body a move while rotating on both sides of the spine, producing an acupressure effect. I can demonstrate it.

In particular, in the present invention, the screw shaft 5 is provided with a cover 6 in the form of a side wall, so there is no risk of the shaft 5 coming into contact with other objects when it rotates, making it extremely safe. Therefore, there is no possibility that dust or the like may adhere to the shaft and cause any inconvenience in the movement of the feed nut 51.

In addition, this cover 6 not only functions as a cover for the screw shaft 5, but also has flanges 61.61 which are designed to hold guide rollers 24.24 of anti-swing plates 23...23 formed on the moving frame 2. I changed it to Rollard...
Even if the movable frame 2 tries to tilt (forward or backward) due to the resistance that the movable frame 1 receives when moving, the uprightness of the movable frame 2 is maintained by the action of the guide rollers 24, 24 and the flanges 61 and 61. It can lean down and move smoothly.

Furthermore, the supporting leg 21 of the moving frame 2 has a vertically long floating hole 22°2.
2, and the support shaft 3 of the roller rod 1 was loosely inserted into the blind holes 22, 22, so that the guide rails 4, 4
Even if the roller road 1 is located at the bent part of the guide rail when moving along the guide rail, the moving frame 2 remains as it is, and only the roller road 1 moves as shown in Figures 1 and 3. As illustrated by the dotted line, it has the characteristic of being able to float up and perform effective acupressure action.
