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 laid along the longitudinal direction on the upper surface of the base, and a pine surge roller is provided so as to be freely movable along the guide rails. Further, a drive device is provided at one end in the longitudinal direction of the base, and the pine surge roller is driven to travel by this drive device.

By the way, when a user receives pine surgery using a pine surgery device having such a structure, the user lies face up on the pine surgery device. When the pine surge roller is driven to travel, the pine surge roller travels while pressing the back of the user, so that the user can receive pine surge over the entire back of the user. However, the user's back has an uneven shape, such as a protruding crown and a constricted waist. Therefore, if the pine surge roller runs horizontally on the upper surface of the base, the pine surge roller may strongly press the protruding crown of the user's body, but hardly press the narrow waist. There was a problem in that the user could not receive a pine surge of uniform strength over the whole body. This invention was made based on the above circumstances, and its purpose is to use the pine surge roller to reduce the unevenness of the user's back surface. To provide a pine surge device which allows a user to receive pine surge with uniform strength over the whole body by running along the shape.

One end of a frame 79 having a C-shaped cross section is pivotally attached to the support shaft 78 . Band-shaped leaf springs 80 are provided on both outer surfaces of the frame 79, with their ends fixed to each other. A shaft-like body 8 is provided protruding from the other end of the leaf spring 80, respectively. This shaft-shaped body 81 is connected to through holes 82 that are bored on both sides of the frame 79 by the biasing force of the leaf spring 80.
It protrudes from the inner surface of both sides. Further, first limit switches 8 are provided on the outer surfaces of both sides of the frame 79, respectively.
3 and a second limit switch 84 are fixedly provided on a plate member 85.
4, when the other end side of the leaf spring 80 is elastically deformed in a direction away from the outer surface of the frame 79, these leaf springs 80
activated by. As shown in FIG. 12, the frame 29 is inclined toward the plate-shaped body 71, and a pair of shaft-shaped bodies 81 are engaged with the first and second guide grooves 73 and 74, respectively. Then, when the disk-shaped body 7 rotates as described later, the shaft-shaped body 8 moves relatively in the guide groove 73, 74', and the shaft-shaped body 81 moves toward the first step 75.
Alternatively, when displaced by the second step 76, the leaf 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 rotational 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, for example, clockwise, the rotation direction of the output shaft 35 is changed counterclockwise. In addition, the output shaft 35
If the second limit switch 84 is actuated while the rotation is being rotated counterclockwise, the rotation will be converted clockwise.

On the other hand, on the upper surface of the base 1, a wall member 9o is provided on the outside of the pair of guide rails 9 and at the 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. Furthermore, the base 1 is covered with an exterior fabric 91 made of canvas-like fabric having relatively excellent abrasion resistance and sewn into a bag shape.

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 and guide rail 9 of the pine surge device are made of a flexible material, they bend into a wave shape according to the uneven shape of the user's back surface. In this state, operate the switch box (not shown) and drive the drive source 3 of the drive device 30.
Activate 4. This drive source 34 operates and the output shaft 35
When rotates clockwise as indicated by arrow X in FIG. 5, the first pulley 37 and fourth pulley 44 rotate in the same direction, and the second seesaw 40 and third pulley 42 rotate in the opposite direction. Rotate.

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. Since the belt 5 is fed from
The portion of the guide rail 9 inserted into the upper passage 14 runs in the direction shown by arrow 2 in FIG. When the belt 5θ runs in this manner, the pair of holding bodies 51 are linked to the running of the belt 50, so that this □holding body 51
A plurality of pine surge rows 267 provided on the hollow shaft 52 of
arrow S in FIG. 11 due to contact with the inner surface of the exterior material 91.
It travels while rotating in the direction shown, and its protrusion 68 hits the back of the user. That is, the pine surge roller 67 is driven to run along the guide rail 9 that is bent together with the base 1 according to the uneven shape of the back surface of the user.

Therefore, the pine surgery row 267 applies pine surgery to the user's entire body with substantially uniform strength.

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-like body 71 is interlocked.

When the plate-shaped body 7 rotates in the direction of arrow Y, this plate-shaped body 21
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. As the disc-shaped body 71 rotates, one of the ring-shaped bodies 81 engaged with the first guide groove 13 moves to the first stepped 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, so that the running direction of the portion of the belt 50 inserted into the upper passage 14 is opposite to the direction of the arrow 2. become. Therefore, since the pair of holders 51 are interlocked with the running of the belt 50, the pine surge roller 6
7, users will be given a pine surge. Further, at this time, the plate-shaped body 7 rotates in the opposite direction to that previously, 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-shaped body 81 engaged with the second guide groove 73 is displaced by the second step 26, the other leaf spring 80 to which this shaft-shaped body 81 is attached is moved to the 14th
As shown by the chain line in the figure, it is elastically deformed and the second limit switch 83 is activated. Then, since the rotation direction of the output shaft 350 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 5I are reciprocated over a distance corresponding to the rotational speed of the plate-like body 71 at which the first limit switch 82 or the second limit switch 83 is activated.
・When the pine surge device is not in use, it can be folded into two from the center in the longitudinal direction of the base 1, as shown in FIGS. 17 and 18. That is, the longitudinal center portions of the base 1 and the guide rail 9 each have a bendable first flexible portion 7.
and the second flexible portion 18, the base body 1 and the idle rail 9 can be folded into two together with the wall member 90 provided on the upper surface of the base body 1. 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 1, the other side slides freely, so there is no possibility that the guide rail 9 is deflected or subjected to large bending stress, making it difficult to bend. , 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.

As described above, in the present invention, the base constituting the pine surge device and the guide rail provided on the upper surface of the base and on which the pine surge roller runs are made of a flexible material. Therefore, when the above-mentioned pine surge device is placed on a pinerest and a user lies down on it, the base body and the guide rail are bent into a wave shape according to the uneven shape of the user's body. Therefore, since the pine surge roller runs along the curved guide rail, the user's entire body, which is uneven, is pine surged with a substantially uniform force.
