A pair of holders 90 are provided between the pair of guide rails 10, as shown in FIG. 1, and spaced apart from each other at a predetermined interval along the longitudinal direction of the guide rail 10. This holder 90 is equipped with a hollow shaft 92 as shown in FIG. Both ends of the hollow shaft 92 are removably fitted into attachment holes 96 formed in the support 94. A screw shaft 98 is inserted through the hollow shaft 92 . Both ends of the threaded shaft 98 on which the male thread 100 is formed protrude from the bottom wall 102 of the mounting hole 96, and a female thread 104 is screwed into the male thread 100 via a washer 106. As shown in FIGS. 3 and 11, a pair of wheels 108 are rotatably provided on the support 94 via a support shaft 110. As shown in FIGS. This wheel 108 runs on the guide surface 24 of the guide rail 10. As shown in FIG. 3, one vertical side of a connecting member 112 having a substantially inverted T-shaped cross section is fixedly attached to one end of the support shaft 110. As shown in FIG. This connecting member 1
The other horizontal side of 12 is the upper passage 1 of the belt 86.

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. 12 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.
are formed respectively. Each guide groove 130,1
32 is provided with a first step portion 134 and a second step portion 136, respectively, which make the guide groove shallower than the other portions. The first step portion 134 is provided at a position R ₁ in the radial direction from the rotation center O of the plate-shaped body 126, and the second step portion 136 is provided at a position R ₂ . R ₁ is greater than R ₂ . Therefore,
The first step portion 134 is located radially outward from the second step portion 136 by a plurality of turns of the guide groove.
Further, a pair of support pieces 138 are provided protrudingly on the mounting plate 62 near the plate-like body 126.

A frame 142 having a substantially C-shaped cross section is pivotally attached to the frame 40 at one end. 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 is in a board state 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 base 1, a wall member 160 is provided on the outside of the pair of guide rails 10 and at one longitudinal end of the base 2, as shown in FIG. This wall member 160 is made of a bendable elastic material, such as urethane foam. Further, the base body 2 is covered with an exterior material 162 made of a cloth having relatively excellent abrasion resistance, such as canvas or nylon cloth, sewn into a bag shape.

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. 11, 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. 4, 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-like body 146 is attached is displaced by the step portion 136 of the
As shown by the chain line in FIG. 4, it is elastically deformed to operate the second limit switch 154. Then, the second
Since the rotational direction of the output shaft 66 of the drive source 64 is changed by the signal from the limit switch 154, 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, the length of the belt 86 wound around one drive pulley and the length of the belt 86 fed out from the other drive pulley are such that the outer diameter of the pulley to be wound gradually increases, As the outer diameter dimensions gradually become smaller, they no longer match.
Then, tension is generated in the belt 86 according to the difference, and this tension is applied to the support pulley 48.
Since it is applied to the guide rail 10 via the frame 42, there is a risk that the guide rail 10 may warp. However, one end of the guide rail 10 is fixed to the base 2, and the other part is slidably held by a support 28, and is molded from synthetic resin, so the length is adjusted by the tension. Dimensions are reduced and will not warp. Therefore, the smooth running of the holding body 90 along the guide rail 10 is not impaired.

Furthermore, when the pine surge device 1 is not in use, it can be folded into three parts from the midway point in the longitudinal direction of the base body 2, as shown in FIG. That is, since the base body 2 and the guide rail 10 are formed into the first flexible part 8 and the second flexible part 40, respectively, in the longitudinal direction, the base body 2 and the guide rail 10 are As shown in FIG. 17, it can be folded into three together with a wall member 160 provided on the top surface of the base 2. Therefore, when not in use, the length of the pine surge device 1 can be reduced to about one-third, making it convenient for storage.

Furthermore, only one longitudinal end of the guide rail 10 is fixed to the base body 2. Therefore, when the guide rail 10 is folded together with the base body 2, the other end side slides freely, so that the guide rail 10 is not bent or subjected to large bending stress and becomes difficult to bend.

In the present invention, the first flexible portion 8 provided in the central portion in the longitudinal direction of the base body 1 may have the structure shown in FIG. 18 or FIG. 19. That is, in the embodiment shown in FIG. 18, the central portion in the longitudinal direction of the base body 2 is removed over the entire width direction. Then, by arranging a large number of strip plates 182 that are bendably connected by hinges 180 in this part, and by connecting both ends of the hinges 180 to the base body 2, the first flexible part 8 is Formed.

Further, in FIG. 19, a flexible member 184 formed in a wave shape and made of an elastic material such as synthetic resin is disposed at the longitudinal center portion of the base body 2. In FIG. This flexible member 1
A pair of attachment pieces 186 are provided at both ends of the 84, and these attachment pieces 186 are fixed to the base body 2.
