It is screwed through 9. The support 53 above has a third
As shown in the figure and FIG. 11, a pair of wheels 60 are rotatably provided by a support shaft 61. As shown in FIG. This wheel 60 runs within the guide surface of the guide rail e. The above-mentioned support shaft 61
As shown in FIG. 3, one vertical side of a connecting member 62 having a substantially inverted T-shaped cross section is fixedly attached to one end of the connector. The other horizontal side of the connecting member 62 is fixed to a portion of the belt 50 that is inserted into the upper passage 14. That is, the vertical side of the connecting member 62 is led out from the gap between the pair of L-shaped pieces 13 forming the upper passage 14 and is fixed to the support shaft 61. Therefore, the holding body 51 is connected to the belt 50 by the connecting member 62, and is interlocked with the running of the belt 50.

Further, a plate member 65 is attached to the other end of the support shaft 61, and the lower end of the plate member 65 is bent at a right angle and inserted into the locking portion 11 of the guide rail 3. Further, four collars 66 are provided on the hollow shaft 52 so as to be rotatable and not to shift in the axial direction. A pine surge roller 67 is attached to each collar 66.

The pine surge roller 67 is made of a relatively hard elastic material such as rubber or synthetic resin, and has a large number of substantially hemispherical protrusions 68 projecting from its outer peripheral surface at predetermined intervals in the circumferential direction. A stopper 69 is provided on the outer peripheral surface of each collar 66 to prevent the pine surge roller 67 from shifting in the axial direction of the collar 66.

On the other hand, the running direction of the belt 50 is controlled by a control device 70 provided inside the case 31 of the drive device 30. This control device 70 includes a plate-shaped body 71 as shown in FIGS. 12 to 14. This plate-shaped body 71 is fixed to the first mounting shaft 38 which is pivotally supported by the mounting plate 33 inside the case 31 with a set screw 72 . Also,
A spiral first guide groove 73 and a spiral second guide groove 74 are formed as guide portions on both side surfaces of the disc-shaped body 71, respectively. A portion of each guide groove 73° 74 has a first step portion 75 and a second step portion 7 that make the guide groove 73° 74 shallower than other portions.

Therefore, the first step 75 is located further in the direction than the second step 76 by a plurality of turns of the guide groove. Further, the mounting plate 33 has a pair of support pieces 77 near the plate-like body 71.
is provided in a protruding manner, and a support shaft 78 is provided on this support piece 77 . This support shaft 78 has a frame 79 with a C-shaped cross section.
is pivoted at one end. Band-shaped leaf springs 80 are provided on both outer surfaces of the frame 79, with their ends fixed to each other. A shaft-shaped body 81 is provided protruding from the other end of the leaf spring 80, respectively.

This shaft-like body 81 projects from through holes 82 formed on both sides of the frame 79 by the biasing force of the leaf spring 80 to the inner surfaces of the both sides. Furthermore, a first limit switch 83 and a second limit switch 84 are provided on both outer surfaces of the frame 79 and are fixed to a plate member 85, respectively.

These limit switches 83 and 84 are actuated by these leaf springs 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. The frame 19 is a plate-shaped body 7 as shown in FIG.
The pair of shaft-shaped bodies 81 are respectively engaged with the 1st and second guide grooves 73 and 74. Then, when the disk-shaped body 71 rotates as described later, the shaft-shaped body 81 moves relatively in the guide groove 73, 74, and the shaft-shaped body 81 moves toward the first step 75 or the second step 75. Stepped portion 76
When the leaf spring 80 is displaced, the leaf spring 80 is elastically deformed.

Further, the limit switches 83 and 114 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 activated while the output shaft 35 is being rotated clockwise, for example.

The rotational direction of the output shaft 35 is changed counterclockwise. Furthermore, if the second limit switch 84 is activated 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. Further, the base body 1 is covered with an exterior material 91 which is a canvas.

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. First, install the pine surge device. Then, since the base body 1 and guide rail 9 of the pine surge device are made of flexible materials, they bend in accordance with the uneven shape of the user's back surface.

In this state, a switch box (not shown) is operated to activate the drive source 34 of the drive device 30. When this drive source 34 operates and the output shaft 35 rotates in the clockwise direction indicated by the arrow X in FIG. and the third pulley 42 rotate in opposite directions.

Therefore, the pair of belts 50 are wound around the first pulley 37 and the fourth pulley 44, respectively, and the belts 50 are wound around the second pulley 40 and the third pulley 42 by an amount corresponding to the wound length. The above belt 5
The portion of the guide rail 9 inserted into the upper passage I4 runs in the direction shown by arrow Z in FIG. When the belt 50 runs in this way, the pair of holders 51 are linked to the running of the belt 50, so that the hollow shaft 52 of the holder 51
A plurality of pine surge rollers 67 provided on the exterior surface 91
When it comes into contact with the inner surface of the user, it runs while rotating in the direction shown by arrow S in FIG. 11, and the 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 control device 7
0 disk-like body 71 is interlocked.

When the plate-like body 71 rotates in the direction of arrow Y, this plate-like body 71
1st. The shaft-like bodies 81 respectively engaged with the second guide grooves 73, 74 move relatively along the guide grooves 73, 74, and the frame 79 rotates in the direction shown by arrow T in FIG. Then, due to the rotation of the plate-like body 71, one shaft-like body 81 engaged with the first guide groove 73 is moved to the first step portion 75.
When the leaf spring 8 to which the shaft-like body 81 is attached is displaced in the direction of protruding from the first guide groove 73,
0 is elastically deformed as shown by the chain line in FIG. 14 and operates the first limit switch 83. Then, the drive source 34 is activated by the signal from the first limit switch 83.
Since the rotation direction of the output shaft 35 is changed, the belt 50
The running direction of the portion inserted into the upper passage 14 is opposite to the direction of arrow 2. Therefore, since the pair of holders 51 are interlocked with the running of the belt 50, the user is pine-surged by the pine-surge roller 67. Further, at this time, the plate-like body 71 rotates in the opposite direction to that previously, that is, in the opposite direction to each town Y, so the frame 19 rotates in the opposite direction to the arrow T direction. Then, when the other shaft-shaped body 81 engaged with the second guide groove 73 is displaced by the second step 76, the other leaf spring 80 to which this shaft-shaped body 81 is attached is shown in FIG. The second limit switch 83 is actuated by elastic deformation as shown by the chain line. Then, the output shaft 35 of the drive source 34 is activated by a signal from the second limit switch 83.
Since the rotational direction of the holding bodies 5I is changed, the running directions of the pair of holding bodies 5I become two directions again.

In this way, the pair of holders 51 are connected to the first limit switch 82 or the second limit switch 83.
is driven back and forth over a distance corresponding to the rotational speed of the plate-shaped body 71 that is operated.

Also, when not using the pine surge device.

As shown in FIGS. 17 and 18, this can be folded into two from the longitudinal center of the base 1. That is, since the longitudinal center portions of the base 1 and the guide rail 9 are formed into the bendable first flexible portion 7 and second flexible portion 18, respectively, the base 1, the guide, and the rail 9 are bent.
and the wall member 90 provided on the upper surface of the base 1.
It can be folded into. 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 fixed to the base body 1 only at one end in the longitudinal direction. Therefore, the guide rail 9
When the guide rail 9 is folded together with the base body I, the other side slides freely, so that the guide rail 9 is not bent or subjected to large bending stress and becomes difficult to bend.

In this embodiment, the base body 1 may be formed only of the first plate-like body 2 without using the second plate-like body 3 and the reinforcing plate 4. Further, the power transmission strip may be a chain, a wire, or the like in addition to a belt.

In the present invention, the first flexible portion 7 provided in the central portion in the longitudinal direction of the base body 1 may have the structure shown in FIG. 19 or FIG. 20.

That is, in the embodiment shown in FIG. 19, the central portion in the longitudinal direction of the first plate-shaped body 2 is removed over the entire width direction. A large number of band-shaped plates 101 are arranged in this part, and the hinges 100 are connected to each other so as to be flexible.
By connecting both ends of 00 to the first plate-shaped body 2,
The first flexible portion 2 was formed.

Further, in FIG. 20, a flexible member 105 formed in a wave shape and made of an elastic material such as synthetic resin is arranged in the longitudinal center portion of the first plate-shaped body 2. In FIG.

A pair of attachment pieces 106 are provided at both ends of the flexible member 105, and the attachment pieces 106 are fixed to the first plate-shaped body 2.

In addition, in the embodiment shown in FIGS. 19 and 20, fax
Although the second plate-like body 3 and the reinforcing plate 4 are not provided on the upper surface of the plate-like body 2, they may not be provided.

As described above, in the present invention, a flexible portion is provided in the longitudinal center portion of the base of the pine surge device and in the longitudinal center portion of the guide rail disposed on the base, respectively, to enable these to be bent. Therefore, when the pine surge device is not in use, it can be folded in two from the flexible portion to approximately halve the length.
It has the advantage of being easy to store when not in use.
