Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a driving method in which an acupressure body including an acupressure roller or the like can be moved back and forth by a predetermined length using a wire stretched between a driving drum and a driven pulley.

For example, a bed-type roller pine surge machine generally has an open top surface and a bed-type main body with a cloth stretched over the opening surface, in which an acupressure body including a rotatable acupressure roller is disposed in a freely movable manner. The roller can apply appropriate finger pressure to the back of a human body lying on the surface of the cloth. Conventionally, the method of making the finger pressure roller reciprocate is to use a drive pulley attached to a drive motor. A wire is stretched between the drive pulley and the driven pulley, and both ends of the wire are attached to the front and rear of the acupressure body equipped with the acupressure roller, and the drive pulley is rotated in an appropriate direction to move the acupressure body back and forth. There was one that was designed to be driven.

However, according to this type of conventional method, a wire formed into an endless shape by simply attaching both ends to the front and rear of the acupressure body is hung between a drive pulley and a driven pulley, and the acupressure body is moved back and forth by the rotation of the drive pulley. Since the acupressure body is moved by engaging each pulley with the frictional resistance of the wire, the wire may not be fully tensioned between the pulleys, In addition, if the wire stretches during use, the frictional resistance between the wire and each of the boots becomes smaller, and each of the boots can rotate and transmit its rotational force to the wire. First, there is a problem in that the acupressure body cannot be driven in an appropriate direction.

The present invention has been made in view of the above-mentioned problems, and includes fixing one end of each of two wires having a predetermined length to both sides of the outer circumferential surface of a driving drum, and connecting both wires. After winding the drum in respective relative directions,
The other end of one wire is supported by a spring on the rear end of an acupressure body having an acupressure roller, and the other end of the other wire is supported by a spring on the front end of the acupressure body via a driven pulley. By forward and reverse rotation, the acupressure body is driven so that it can be moved backward by one of the wires and forward by the other wire, and the acupressure body is always moved in an appropriate position regardless of the slackness of the wire. The present invention provides a method for driving an acupressure body that can be moved in the direction ItIJ'l.

The driving method of the present invention will be explained in detail below based on an embodiment shown in the drawings.

Figures 1 and 2 show a bed-type roller pine surge machine, which has an open top surface and a cloth stretched over the opening surface, and a pair of rails (
2), a frame body (3) that can travel back and forth as required on the rails (2) of the body (1), and a frame body (3) with The acupressure body (4) is installed perpendicularly to the running direction at a predetermined interval. stretched between the driven pulley (9)
The wires (6a) and (6b) are made to reciprocate within a predetermined range so that appropriate acupressure can be applied to the back of a human body lying on the surface of the cloth.

Accordingly, in the driving method of the present invention, the acupressure body (4) is stretched between the driving drum (5) and the driven pulley (9).
This is a driving method in which the wires (6a) and (6b) are used to move back and forth, and as shown in Figure 3, the driving drum (
5) Wires (6a) of a predetermined length are placed on both sides of the outer peripheral surface of the
(6b) are fixed with bolts (7), etc., and the required lengths of these wires (6a) and (6b) are wound in the respective n directions. As shown in Fig. 5, the other end of the one wire (6a) is supported by the rear end of the frame (3) via a spring (8) or the like so that the tension can be adjusted, and the other wire (6b), etc. Connect the end to the driven boob IJ (9)
ft, the front end of the frame (3) is tension-adjustably supported by a spring σ0), and the drive drum (5) is rotated in an appropriate direction to move the frame (3) to the one side. The other wire (6b) is used to move backward.
) so that it can be moved forward.

In addition, as shown in FIG. 4, each of the wires (6a) and (6b) is coated with vinyl or the like to prevent corrosion of the wire material such as steel wire (wire material 01), thereby increasing its durability. It is desirable to configure the system so that it is rich in information.

Therefore, when driving the acupressure body using the method shown in the above embodiment, one wire is hung between the drive pulley and the driven pulley as in the conventional method, and both ends of the wire are connected to the front and back of the acupressure body. Unlike the method of attaching the acupressure body endlessly to the body and moving the acupressure body back and forth, two wires having a predetermined length are wound in opposite directions on both sides of the outer peripheral surface of the drive drum. Since each wire moves the acupressure body back and forth, even if there is slack in the hanging state between each wire and the finger 1 body, the acupressure body can be moved without causing the drive drum to rotate. The acupressure body can be moved in a desired direction, and even if the wire is extended, the acupressure body can be moved back and forth without any effect.

Therefore, the driving method of the present invention is highly valuable because it can reliably move the acupressure body in an appropriate direction regardless of the magnitude of the frictional resistance between the wire and the boob or drum.

In the above embodiment, the method of the present invention is applied to a bed-type roller pine surgery machine, but the present invention is of course not limited to this, and can also be applied to a chair-type pine surgery machine, etc. It can be applied to any object that can be moved in the forward and reverse directions.
