The second step portion ₁₃₆ is provided at a position R ₁ in the radial direction from the rotation center 0 of the second step portion 136 . 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 protruding from the mounting plate 62 near the plate-like body 126.
A support shaft 140 is provided. This support shaft 14
A frame 142 having a substantially C-shaped cross section is pivotally attached to one end of the frame 142. 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-like body 146 has through holes 148 bored on both sides of the frame 142 by the biasing force of the leaf spring 144.
It protrudes from the inner surface of both sides. Further, a first limit switch 150 and a second limit switch 1 are provided on both outer surfaces of the frame 142, respectively.
52 are fixedly provided to the plate material 154. 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-like bodies 146 are engaged with the first and second guide grooves 130 and 132, respectively. Then, when the disc-shaped body 126 rotates as described later, the shaft-shaped body 146 moves into the guide grooves 130 and 1.

52 and 154 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 actuated while the output shaft 66 is being rotated counterclockwise, this 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 1 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, the pine surge device 1 is placed on a pinerest 170 as shown in FIG. 16, and a user lies on the pinerest 170 facing upward. Then, since the base body 2 and guide rail 10 of the pine surgery device 1 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 64 of the drive device 56. This drive source 64 operates and the output shaft 66
When rotates clockwise as shown by arrow X in Figure 5,
First driving pulley 70 and fourth driving pulley 8
4 rotates in the same direction, and the second driving pulley 76
and the third drive pulley 80 rotate in opposite directions. Therefore, the pair of belts 86 are connected to the first driving pulley 70 and the fourth driving pulley 84, respectively.
and the second driving pulley 76 and the third driving pulley 80 depending on the winding.
5, 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.

Also, when the pine surge device 1 is not used,
As shown in FIGS. 17 and 18, the base body 2 can be folded into three parts from the midway point in the longitudinal direction. That is, since the intermediate portions in the longitudinal direction of the base body 2 and the guide rail 10 are formed into the bendable first flexible portion 8 and the second flexible portion 40, respectively, the base body 2 and the guide rail 10 are 2
It can be folded into three parts together with the wall member 160 provided on the top surface of. Therefore, the length of the pine surge device can be reduced to one-third when not in use, 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 addition, in this invention, the first flexible portion 8 provided in the longitudinal center portion 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 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. 20, a flexible member 184 formed in a wave shape and made of an elastic material such as synthetic resin is arranged in the longitudinal center portion of the base body 2. As shown 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.

Further, by changing the positions and numbers of the plurality of first flexible parts 8 and second flexible parts 40 provided on the base body 2 and the guide rail 10, the mattress device 1 can be placed in the state shown in FIG. 21 or in the state shown in FIG. It can be folded into the state shown in Figure 22. FIG. 21 shows a case where two first flexible parts 8 and two second flexible parts 40 are provided on the base 2 and guide rail 10, and FIG. 22 shows a case where three are provided. . That is, in the present invention, the number of first flexible portions 8 and second flexible portions 40 provided on the base body 2 and the guide rail 10 may be two or more.

Further, in the present invention, the base body 1 does not necessarily have to be flexible over its entire length, but only needs to include the first flexible portion 8 that allows the base body 1 to be bent.

As described above, the present invention provides a base body of a pine surge device and a guide rail disposed on the base body, each of which has a plurality of first flexible portions and a plurality of second flexible portions for bending these into a plurality of pieces. has been established. Therefore, when the pine surge device is not in use, it can be folded into multiple pieces from the flexible portion to make its length sufficiently shorter than when in use, making it convenient to store and handle when not in use. be.
