Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pine surgery device that can perform pine surgery on a user's entire body.

Generally, the above-mentioned pine surge device has a pair of guide rails installed on the top surface of the base body along the longitudinal direction, and a pine surge roller is provided so as to be freely movable along the guide rails. This pine surge roller is caused to reciprocate along the longitudinal direction of the base by a drive device. Therefore, when the user lies face up on the pine surge device, the user can receive pine surge all over the body by the pine surge roller.

By the way, the above drive device conventionally includes a drive source disposed at one end in the longitudinal direction of the base, a first pulley rotationally driven by the drive source, and a second pulley disposed at the other end in the longitudinal direction of the base. and a wire stretched between the first pulley and the second pulley. The pine surge roller is indirectly connected to the wire, and when the wire is moved by the rotation of the first pulley, the pine surge roller is interlocked. However, according to a drive device having such a structure, the length of the base must be approximately 2 m, which is longer than the height of the user, so that the length of the base must be approximately 2 m, which is longer than the height of the user. The wire stretched between the pair of wires also becomes long. Therefore, when the wire is run, the slack side of the wire becomes loose and comes into contact with the top surface of the base, so the contact resistance prevents the pine surge roller from running smoothly and the top surface of the base is rubbed by the wire. This caused early damage to the product.

This invention was made based on the above-mentioned circumstances, and its purpose is to provide a pine surge device that prevents a power transmission strip such as a wire from sagging due to running and coming into contact with the upper surface of the base. Our goal is to provide the following.

A fourth gear 44 that meshes with the third drive pulley 42 and a fourth drive pulley 45 that is paired with the third drive pulley 42 are fitted. Therefore, when the output shaft 35 is rotationally driven, the first gear 36 and the second gear 39 rotate in opposite directions, and the third gear 41 and fourth gear 44 rotate in opposite directions. . Note that the first to fourth gears rotate at the same number of rotations.

The first driving pulley 37 and the fourth driving pulley 44

This belt 5° is connected to the first belt as shown in FIG. The fourth drive pulley 37, 44 passes through the upper passage 14 of the guide rail 9, and the midway portion led out from the upper passage 14 is hung on a support pulley 22 provided on the pedestal 19. The running direction of the belt 50 is changed by 180 degrees tt by the support pulley 22, and then the belt 50 passes through the opening 247) formed in the guide rail 9 to the lower passage 1.
5 has been passed. At the opening 24, the running direction of the belt 50 is slightly changed by the pitching roll 2o. The other end of the belt 50 led out from the lower passage 15 is attached to the second drive pulley 40.
and the third drive pulley 42, respectively. Therefore, the first driving pulleys 37 that are paired with each other
When the second driving pulley 40 or the third driving pulley 42 and the fourth driving pulley 44 are rotated in opposite directions, the bell) 511+ is wound around one of the driving pulleys, and the winding The length taken is sent out from the other pulley. For example, in FIG. 5, when the first driving pulley 37 is rotated in the direction of the arrow X and the second driving pulley 40 is rotated in the direction of the arrow Y, the portion of the belt 50 inserted into the upper passage 14 is rotated in the direction of the arrow 2. Run to.

Between the pair of guide rails 9, as shown in FIG. 1, a pair of holders 51 are provided which are spaced apart at a predetermined interval along the longitudinal direction of the guide rail ◇. This holder 51 is equipped with a hollow shaft 52 as shown in FIG. Both ends of this hollow shaft 52 have mounting holes 54 formed in the support 53.
It is removably fitted to the A screw shaft 55 is inserted through the hollow shaft 52 . Male thread 56 of this screw shaft 55
Both ends protrude from the bottom wall 57 of the mounting hole 54, and a female thread 58 is attached to the male thread 56 with a washer 59.
It is screwed through. As shown in FIGS. 3 and 11, a pair of wheels 6o are rotatably provided on the support 53 by means of a support shaft 61. As shown in FIGS. This wheel 60 runs on the guide surface 16 of the guide rail 9. 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 the portion of the belt 5o that is inserted into the upper passage 14. That is, one 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 511d 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 8. In addition, the hollow shaft 52
Four collars 66 are provided in a rotatable manner without shifting 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 sliding 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 7o 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 .

Further, a spiral first guide groove 73 and a spiral second guide groove 24 are formed as guide portions on both side surfaces of the disc-shaped body 71, respectively. Each guide groove7. ? , 74 are provided with a first stepped portion 75 and a second stepped portion 76, respectively, which leak the guide grooves 73 and 74 more than other portions. The first step portion 75 is provided at a position R in the radial direction from the rotation center 0 of the plate-shaped body 71, and the second step portion 76 is provided at a position R2. R1 is also larger than R2. Therefore, the first step portion 75 is also located radially outward from the second step portion 76 by a plurality of turns of the guide groove. Further, a pair of support pieces 77 are provided protruding from the mounting plate 33 near the plate-shaped body 71, and a support shaft 78 is provided on the support pieces 77. This support shaft 7
A frame 79 having a C-shaped cross section is pivotally attached to one end of the frame 8 . Band-shaped plate springs 8o are provided on both outer surfaces of the frame 79, with their ends fixedly attached. A shaft-like body 81 is provided protruding from the other end of the leaf spring 8o.

This shaft-shaped body 81 projects from through holes 82 formed on both sides of the frame 79 to the inner surfaces of the both sides by the biasing force of the leaf spring 8o. Furthermore, a first limit switch 83 and a second limit switch 84 are provided on both outer surfaces of the frame 79, respectively, and are fixed to a plate member 85.

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 seven frames 79. The frame 79 is a plate-shaped body 7 as shown in FIG.
1, and the pair of shaft-like bodies 81 are tilted in the first and second directions, respectively.
The shaft-like body 81 is engaged with the second guide groove 73.74. When the plate-like body 71 rotates as described later, the shaft-like body 81 moves relatively through the guide groove 73.74. The shaft-shaped body 81 is connected to the first step 75 or the second step 76.
When displaced by , the plate 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 rotation 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 clockwise, the rotation direction of the output shaft 35 is changed counterclockwise. Also, when the output shaft 35 is rotated counterclockwise, the second limit switch 8
4 is activated, its 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 covered with an exterior portion 91 made of a bendable elastic material, such as urethane foam.

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, lie down in the Matsusage outfit. Then, since the base body 1 of the pine surgery device is made of a flexible material, it bends according to 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 second pulley 40 and the third pulley 42 are wound around the second pulley 40 and the third pulley 42 by an amount corresponding to the wound length. Since the belt 50 is fed from the upper passage 1 of the guide rail 9 of the belt 50,
4 runs in the direction shown by arrow 2 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 the holders 51
A plurality of pine surge rollers 6 provided on the hollow shaft 52 of 1
7 travels while rotating in the direction shown by arrow S in FIG. 11 due to contact with the inner surface of the exterior part 91, and the protrusion 68 hits the back of the user. That is, the belt 50 is wound around one driving pulley 37 and 45 of the pair, and the belt 50 is wound around the other driving pulley 40 by the amount of winding.
．． 42, so there is almost no slack in #1. Furthermore, since the belt 50 is inserted through the upper passage 14 and the lower passage 15 of the guide rail 9, even if it becomes somewhat wavy as it travels, it will not come into contact with the upper surface of the substrate 1 or the like. That is, the entire belt 50 runs smoothly under a substantially constant tension.

On the other hand, when the output shaft 35 rotates in the direction of the arrow X, the first mounting shaft 38 rotates in the direction of the arrow Y, and the control device 7
0 disk-shaped body 21 is interlocked.

When the plate-like body 71 rotates in the direction of arrow Y, this plate-like body 71
The shaft-like body 81 engaged with the first and second guide grooves 73 and 74 moves relatively along the guide grooves 73 and 74, and the frame 79 moves in the direction shown by arrow T in FIG. Rotate. 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 displaced in the direction of protruding from the first guide groove 73, one of the leaf springs 8 to which this shaft-like body 81 is attached
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).
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-shaped body 71 rotates in the opposite direction to that previously described, 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 26, the other plate spring 80 to which this shaft-like body 81 is attached is moved to the first
As shown by the chain line in FIG. 4, it is elastically deformed and the second limit switch 83 is activated. Then, since the rotational direction of the output shaft 35 of the drive source 34 is changed by the signal from the second limit switch 83, the running directions of the pair of holders 51 become two directions again.

In this way, the pair of holders 51 are reciprocated over a distance corresponding to the rotational speed of the plate-shaped body 71 at which the first limit switch 82 or the second limit switch 83 is activated.

Further, when the pine surge device is not used, the binding can be folded into two from the longitudinal center portion of the base body 1, as shown in FIGS. 17 and 18. That is, the base l
Since the longitudinal center portion of the guide rail 9 and the guide rail 9 are formed into a bendable first flexible portion 7 and a second flexible portion 18, respectively, the base body 1 and the guide rail 9 are connected to the base body 1.
It can be folded into two together with the wall member 90 provided on the top surface. 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 ID rail 9
When the guide rail 9 is folded together with the base body 1, the other side slides freely, so there is no problem if the guide rail 9 is bent or subjected to large bending stress, making it 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. In addition to the belt, the power transmission strip may be a chain, wire, or the like.

As described above, this invention has an upper passage and a lower passage formed vertically in the guide rail that guides the movement of the pine surge roller, and a power transmission strip for driving the pine surge roller is inserted into this passage. Even if the power transmission strip becomes slack, it can be made to run smoothly along the passage. Moreover, since each of the passages described above is integrally formed with the guide rail, no separate member is required to form the passages, making it possible to achieve economical and compact construction.

In addition, since the power transmission strip passes through a passage that is divided vertically, even if the vertical distance between the upper and lower portions of the power transmission strip is sufficiently small, they will not be able to reach each other. There is no contact. Therefore, only a small amount of space is required for tensioning the power transmission strip, and this also allows the device to be made more compact.
