It is fixedly provided. These limit switches 83 and 84 are actuated by the leaf spring 80 when the other end of the leaf spring 80 is elastically deformed in a direction away from the outer surface of the frame 79. As shown in FIG. 12, the frame 79 is inclined toward the plate-shaped body 71, and a pair of shaft-shaped bodies 81 are engaged with the first and second guide grooves 73 and 74, respectively. Then, when the disc-shaped body 71 rotates as described later, the shaft-shaped body 81 moves into the guide grooves 73 and 74.
, the shaft-shaped body 81
When the plate spring 80 is displaced by the first step 75 or the second step 76, the leaf spring 80 is elastically deformed. Further, the limit switches 83 and 84 are electrically connected to the drive source 34 of the drive device 30, and control the rotational direction of the output shaft 35 of the drive source 34. That is, if the first limit switch 83 is operated while the output shaft 35 is being rotated, for example, clockwise, the direction of rotation of the output shaft 35 is changed counterclockwise. Further, if the second limit switch 84 is operated while the output shaft 35 is being rotated counterclockwise, the rotation is converted clockwise.

On the other hand, on the upper surface of the base 1, a wall member 90 is provided on the outside of the pair of guide rails 9 and at one longitudinal end of the base 1, as shown in FIG. This wall member 90 is made of a bendable elastic material, such as urethane foam. Furthermore, the base body 1 is covered with an exterior material 91 made of a cloth having relatively excellent abrasion resistance, such as canvas or nylon, sewn into a bag shape.

Note that the drive device 30 can be remotely operated by a switch box (not shown).

Next, the case where the pine surgery device having the above structure is used will be explained. When the user lies face up on the pine surge device, a switch box (not shown) is operated to activate the drive source 34 of the drive device 30. This drive source 34 operates and the output shaft 3
5 rotates in the clockwise direction indicated by the arrow X in FIG. 5, the first pulley 37 and the fourth pulley 44 rotate in the same direction, and the second pulley 40 and the third pulley 42 rotate in the opposite direction. Rotate to. Therefore, the pair of belts 50 are wound around the first pulley 37 and the fourth pulley 44, respectively, and are wound around the second pulley 40 and the third pulley by an amount corresponding to the wound length. 42, the portion of the belt 50 inserted into the upper passage 14 of the guide rail 9 runs in the direction shown by arrow Z in FIG. When the belt 50 runs in this manner, the pair of holders 51 are interlocked with the running of the belt 50, so that the plurality of pine surge rollers 67 provided on the hollow shaft 52 of the holder 51 are connected to the inner surface of the exterior fabric 91. Upon contact, it runs while rotating in the direction shown by arrow S in FIG. 11, and its protrusion 68 hits the back of the user.

On the other hand, when the output shaft 35 rotates in the direction of arrow X,
The first mounting shaft 38 rotates in the direction of arrow Y, and the plate-shaped body 71 of the control device 70 is interlocked with the rotation. When the disk-like body 71 rotates in the direction of arrow Y, this disk-like body 7
The shaft-like body 81 engaged with the first and second guide grooves 73 and 74 of 1 moves relatively along the guide grooves 73 and 74, and the frame 79 moves in the direction shown by arrow T in FIG. Rotate to. Then, due to the rotation of the plate-like body 71, one of the shaft-like bodies 81 engaged with the first guide groove 73 is displaced by the first step portion 75 in the direction of protruding from the first guide groove 73. When the shaft-shaped body 81 is attached to one of the leaf springs 8
0 is elastically deformed as shown by the chain line in FIG. 14 and operates the first limit switch 83. Then, the rotation direction of the output shaft 35 of the drive source 34 is changed by the signal from the first limit switch 83, so that the running direction of the portion of the belt 50 inserted into the upper passage 14 is opposite to the direction of arrow Z. become the direction. Therefore, since the pair of holding bodies 51 are interlocked with the running of the belt 50, the pine surge roller 6
7 causes the user to be pine-surged. Further, at this time, the plate-shaped body 71 rotates in the opposite direction to that previously, that is, in the opposite direction to the arrow Y, so the frame 79 rotates in the opposite direction to the arrow T direction. Then, when the other shaft-like body 81 engaged with the second guide groove 73 is displaced by the second step portion 76, this shaft-like body 8
The other leaf spring 80 to which the limit switch 1 is attached is elastically deformed as shown by the chain line in FIG. 14 to operate the second limit switch 83. Then, the rotational direction of the output shaft 35 of the drive source 34 is changed by the signal from the second limit switch 83, so that the running direction of the pair of holders 51 becomes the Z direction again.

In this way, the pair of holders 51 are connected to the first
The limit switch 82 or the second limit switch 83 is reciprocated over a distance corresponding to the number of rotations of the plate-shaped body 71 that is activated.

Also, when not using the pine surge device,
As shown in FIGS. 16 and 17, the base body 1 can be folded into two from the center in the longitudinal direction. That is, since the longitudinal center portions of the base body 1 and the guide rail 9 are the bendable connecting member 3 and the flexible portion 18, respectively, the base body 1 and the guide rail 9 are provided on the upper surface of the base body 1. It can be folded into two together with the wall member 90.
Therefore, the length of the pine surge device can be reduced to about half when not in use, making it convenient for storage.

Further, the guide rail 9 is slidably held on the base body 1 by a holding member 16a.
Therefore, when the guide rail 9 is folded together with the base 1, it slides freely according to the bending of the base 1, which causes deflection and large bending stress on the guide rail 9, making it difficult to bend. Never.

In the above embodiment, the base body 1 is formed of two plate-like bodies 2 and one connecting member 3, but for example, the plate-like body 2 is divided into three parts, and these plate-like bodies 2 are formed by two connecting members. 3, the base body 1 can be folded into three parts. In this case, it goes without saying that the guide rail 9 should be provided with two flexible parts 18. In other words, the number of plate-shaped bodies 2 forming the base 1 is 2.
It is not limited to the number of sheets, but may be two or more.

As described above, this invention consists of a base body of a pine surge device that is divided into a plurality of parts, a bendable connecting member connecting these base bodies, and a connecting member of a guide rail laid on this base body. A portion corresponding to the member is formed into a bendable flexible portion, and a pine surge roller is integrally connected to a bendable belt provided so as to be able to run along the guide rail, and the belt is attached along the longitudinal direction of the base. The vehicle is driven by a drive device installed at one end in the direction. Therefore, when the pine surge device is not used, it can be folded from the connecting member to make its length smaller than when in use, making it easier to store and handle when not in use. Further, the pine surge roller is connected to a bendable belt, and this belt is driven to run by a drive device provided at one end in the longitudinal direction of the base. Therefore, regardless of the position of the belt that drives the pine surge roller and the shaft that supports the pine surge roller, there is no problem when bending the base, so the pine surge roller cannot be moved in a predetermined position when bending the base. The base can be folded without returning to the original position.
