The other horizontal side of 12 is the upper passage 1 of the belt 86.
It is fixed to the part inserted through 4. That is, one vertical side of the connecting member 112 is led out from the gap between the pair of L-shaped pieces 18 forming the upper passage 20 and is fixed to the support shaft 110. Therefore, the holding body 90 is connected to the belt 86 by the connecting member 112, and is interlocked with the movement of the belt 86. Furthermore, the support shaft 11
A plate member 114 is attached to the other end of the guide rail 10, and the lower end of the plate member 114 is bent at a right angle and inserted into the locking portion 14 of the guide rail 10. Furthermore, four collars 116 are provided on the hollow shaft 92 in a state that they are rotatable and do not shift in the axial direction. A pine surge roller 118 is attached to each collar 116. This pine surge roller 118 is molded from a relatively hard elastic material such as rubber or synthetic resin, and has a large number of substantially hemispherical protrusions 120 protruding from its outer peripheral surface at predetermined intervals in the circumferential direction. . In addition, each color 11
A stopper 122 is provided on the outer peripheral surface of the collar 6 to prevent the pine surge roller 118 from shifting in the axial direction of the collar 116.

On the other hand, the running direction of the belt 86 is controlled by a control device 12 provided in the case 58 of the drive device 56.
Controlled by 4. This control device 124 is
As shown in FIGS. 11 to 14, the plate-shaped body 126
It is equipped with This disk-shaped body 126 is the case 5
It is fixed by a set screw 128 to the first mounting shaft 72 which is pivotally supported on the mounting plate 62 in the mounting plate 8 .
In addition, a spiral first guide groove 130 and a second guide groove 132 are provided on both sides of the disc-shaped body 126 as guide portions.

Band-shaped leaf springs 144 are provided on both outer surfaces of the frame 142, with one end fixed to each. A shaft-like body 146 is provided protruding from the other end of the leaf spring 144, respectively. This shaft-shaped body 146 is connected to the through holes 14 bored on both sides of the frame 142 by the biasing force of the leaf spring 144.
8 and protrudes toward the inner surfaces of both sides. Also,
A first limit switch 150 and a second limit switch 152 are provided on both outer surfaces of the frame 142 and are fixed to a plate member 154, respectively. These limit switches 152 and 154 are actuated by the leaf spring 144 when the other end of the leaf spring 144 is elastically deformed in a direction away from the outer surface of the frame 142. The frame 142 has a plate-like body 126 as shown in FIG.
The pair of shaft-shaped bodies 146 are engaged with the first and second guide grooves 130 and 132, respectively. Then, when the disk-shaped body 126 rotates as described later, the shaft-shaped body 146 moves into the guide grooves 130 and 1.
32 will move relatively, and the shaft-like body 146 will move toward the first step 134 or the second step 1.
36 causes the leaf spring 144 to elastically deform. In addition, the above limit switch 1
50 and 152 are electrically connected to the drive source 64 of the drive device 56, and control the rotational direction of the output shaft 66 of the drive source 64. That is, if the first limit switch 152 is operated while the output shaft 66 is being rotated, for example, clockwise, the direction of rotation of the output shaft 66 is changed counterclockwise. Furthermore, if the second limit switch 154 is operated while the output shaft 66 is being rotated counterclockwise, the rotation is converted clockwise.

On the other hand, on the upper surface of the support member 2, a wall member 16 is provided outside the pair of guide rails 10 as shown in FIG.
0 is set. This wall member 160 is made of a bendable elastic material, such as urethane foam. Further, the upper and lower surfaces of the support member 2 are covered with an exterior material 162 made of a bag-shaped cloth sewn from a cloth having relatively excellent wear resistance, such as canvas or nylon cloth.

The drive device 56 can be remotely operated by a switch box (not shown).

Next, a case where the pine surgery device 1 having the above structure is used will be explained. First, when the user lies face up on the pine surgery device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. When this drive source 64 operates and the output shaft 66 rotates in the clockwise direction indicated by arrow X in FIG. 5, the first drive pulley 70 and the fourth drive pulley 84 rotate in the same direction, and the The second driving pulley 76 and the third driving pulley 80 rotate in opposite directions. Therefore, the pair of belts 86 are wound around the first driving pulley 70 and the fourth driving pulley 84, respectively, and depending on the winding, the pair of belts 86 are wound around the second driving pulley 76 and the third driving pulley 84, respectively. Since the belt 86 is fed out from the pulley 80, the portion of the belt 86 inserted into the upper passage 20 of the guide rail 10 runs in the direction shown by arrow Z in FIG. When the belt 86 runs in this way, the pair of holders 90 are linked to the running of the belt 86, so that the plurality of pine surge rollers 118 provided on the hollow shaft 92 of the holders 90 are connected to the inner surface of the exterior fabric 162. Upon contact, it runs while rotating in the direction shown by arrow S in FIG. 10, and its protrusion 120 hits the back of the user.

On the other hand, when the output shaft 66 rotates in the direction of arrow X,
The first mounting shaft 72 rotates in the direction of arrow Y, and the plate-shaped body 126 of the control device 124 is interlocked with the rotation.
When the plate-shaped body 126 rotates in the direction of arrow Y, the first and second guide grooves 130 and 132 of this plate-shaped body 126
The shaft-like bodies 146 engaged with the guide grooves 1
30 and 132, and the frame 142 rotates in the direction indicated by arrow T in FIG. One shaft-like body 146 is engaged with the first guide groove 130 by the rotation of the plate-like body 126.
is connected to the first guide groove 13 by the first step portion 134.
When the leaf spring 144 to which this shaft-shaped body 146 is attached is displaced in the direction of protruding from the first
As shown by the chain line in FIG. 3, it is elastically deformed to operate the first limit switch 152. Then, the rotational direction of the output shaft 66 of the drive source 64 is changed by the signal from the first limit switch 152, so that the running direction of the portion of the belt 86 inserted into the upper passage 20 is opposite to the direction of arrow Z. become the direction. Therefore, since the pair of holders 90 are interlocked with the movement of the belt 86, the user is pine-surged by the pine-surge roller 118. Further, at this time, the plate-shaped body 126 rotates in the opposite direction to that previously, that is, in the opposite direction to the arrow Y, so the frame 142 rotates in the opposite direction to the arrow T direction. Then, the other shaft-like body 146 engaged with the second guide groove 132
When the other leaf spring 144 to which this shaft-shaped body 146 is attached is displaced by the step portion 136 of the
As shown by the chain line in the figure, it is elastically deformed to operate the second limit switch 154. Then, the rotational direction of the output shaft 66 of the drive source 64 is changed by the signal from the second limit switch 154, so that the running direction of the pair of holders 90 becomes the Z direction again.

In this way, the pair of holders 90 are connected to the first
The plate-shaped body 1 on which the limit switch 152 or the second limit switch 154 is operated.
It is driven back and forth over a distance corresponding to the rotation speed of 26.

By the way, when the pine surge device 1 is not in use, it can be folded into two from the longitudinal center portion of the base body 2, as shown in FIG.
That is, the central portion in the longitudinal direction of the guide rail 10 is formed into a bendable flexible portion 40, and the portion corresponding to the flexible portion 40 has a plurality of portions that do not prevent the bending of the guide rail 10. Since the support beam 4 is provided, the guide rail 10 can be folded into two together with a wall member 160 provided on the upper surface of the support member 2, as shown in FIG. Therefore, when not in use, the length of the pine surge device 1 can be reduced to about half, making it convenient for storage.

17 and 18 show a second embodiment of the invention. In this embodiment, three supporting members 2 are used.
are arranged at a distance from each other, and a plurality of support bars 4 are provided in each of the two gaps. Furthermore, flexible portions 40 are formed in the pair of guide rails 10 at two locations in the middle in the longitudinal direction corresponding to the support beams 4. According to such a configuration, the pinerest device 1 can be folded into three pieces as shown in FIG.
The length can be reduced to about one third compared to when in use.

FIG. 19 to FIG. 21 respectively show third to fifth embodiments of the present invention, and in each of these embodiments, a wall member 160 provided on the outside of a pair of guide rails 10 disposed facing each other apart from each other. was removed. In the third embodiment shown in FIG. 19, a pair of guide rails 10 are held and fixed by two supporting members 2 so as to be spaced apart from each other in parallel. Also, the second
In the fourth embodiment shown in FIG. 0, a pair of guide rails 10 are held and fixed by three supporting members 2, and
In a fifth embodiment shown in FIG. 1, only one end of the guide rail 10 located on the drive device 56 side is supported by
and the remaining parts were fixed with three support beams 4.

According to the third embodiment, the pine surge device 1 can be folded into two as shown in FIG.
According to the fourth embodiment, it can be folded into three pieces as shown in FIG. Furthermore, according to the fifth embodiment, it can be folded up from the driving device 56 side as shown in FIG.

FIG. 23 shows a sixth embodiment of the present invention, in which the structure of the guide rail 10 is changed from the first embodiment. That is, the guide rail 10 is made of a material that can be bent, such as polypropylene or rubber. In this way, the entire length of the guide rail 10 can be made into the flexible portion 40. It goes without saying that the guide rail 10 made of such a bendable material can also be applied to the second to fifth embodiments.

Further, in the present invention, the base body 2 does not need to be flexible over its entire length, but only needs to be formed to be bendable at a portion corresponding to the bendable flexible portion 40 of the guide rail 10.

As described above, in the present invention, the guide rail that guides the movement of the pine surge roller can be bent by a flexible portion formed on the guide rail. Therefore, when the pine surge device is not in use, it can be folded to make its length sufficiently shorter than when in use, making it convenient to store and handle when not in use.

Moreover, the guide rail that can be bent by the flexible portion formed in at least a portion thereof can be made into a single piece having approximately the same length as the pine surge device, so the guide rail can be divided into a plurality of parts and bent. The configuration can be simplified compared to the case where the two devices are connected in such a way that they can be connected.
