This invention relates to a pine surge machine that can also be used as a pine surge machine.

(Prior Art) A conventional chair-type pine surge machine equipped with two types of pine surge rollers for pine surge of the back and neck is shown in, for example, Japanese Utility Model Application No. 63-43536. However, there is no conventional chair-type pine surgery machine that can be expanded into a bed and can perform pine surgery on the entire body.

(Problems to be Solved by the Invention) In the present invention, a lower pine surge roller is provided at the bottom of the seat that can be raised and lowered by operating a handle, and a front pine surge roller is also attached to the front side of the seat, and the front part can be expanded upward by operating the handle. It is an object of the present invention to provide a pine surgery machine which enables pine surgery of the lower body by moving the user's body and which makes it possible to perform pine surgery of the whole body by expanding the backrest part backwards like a bed.

(B) Structure of the present invention (means for solving the problem) A drive shaft 2 is provided horizontally on the lower side of the backrest portion 1, and a rotating shaft 3 corresponding to the drive shaft 2 is provided on the upper side, and one pair is provided on both sides of each shaft. A chain 7 is installed endlessly between the gears 5 and 6 corresponding to the upper and lower sides, and a middle pine surge roller shaft 8 is installed between the front sides of the chains 7 on both sides. A pair of arm rods 9 to which a middle pine surge roller 10 is rotatably attached.
Secure the bottom edge of the The lower ends of a pair of support plates 12 are fixed to both sides of an upper rotation shaft 11 installed horizontally on the upper stage of the rotation shaft 3, and an upper pine surge roller shaft 13 is rotatably supported at the tip of the support plates. Fix the upper pine surge roller 14. A handle shaft 15 is installed horizontally on the rear side of the rotating shaft 3, and the tips of a pair of operating rods 16 whose lower ends are fixed to the shaft are connected to the upper end of the support plate 12 by a connecting rod 17, and the handle shaft end A handle 18 is provided in the section. A gear 19 is fixed to one side of the upper pine surge roller shaft 13 to rotate it, a gear 20 corresponding to this is fixed to the rotating shaft 3, and a chain 21 is endlessly installed between the two gears. The above-mentioned rotation of the drive shaft 2 is performed by rotating the gear 22 of the first motor M installed at the lower stage and the gear 24 coaxially fixed via the chain 23. In order to control the elevation and descent of the middle stage pine surge roller, an upper stage limit switch 25 and a lower stage limit switch 26 are provided on the way of the roller to rotate the first motor M in forward and reverse directions. The backrest portion 1 configured as described above is pivotally attached to the rear side of a pair of frame-shaped supports 27 made of pipes with a mounting shaft 28, and is movable up and down using the shaft as a fulcrum, and a hydraulic cylinder 29 is connected to the lower end of the backrest portion 1. The end of the cylinder rod 30 is connected to the locking part 32 on the bottom plate 31 to raise and lower the backrest.

A drive shaft 34 is installed horizontally in the center of the lower row of the seat 33,
The lower ends of a pair of support plates 35 attached to both sides of the shaft are swingably attached, and the tips of the support plates are tilted rearward to support the lower pine surge roller shaft 36 at the ends. The lower pine surge roller 37 to be attached to the shaft is not limited to this embodiment and can be freely selected, but to explain what is shown in the embodiment, a pair of disk-shaped mounting plates 38 facing on both sides of the roller shaft 36 are used. Two sets are fixed to each other, and a large number of pine surge roller mounting rods 39 are installed between the peripheral edges of each opposing mounting plate, and one or more elliptical pine surge rollers 37 are rotatably attached to the mounting rods. It is something that A handle shaft 40 is installed horizontally at the lower stage of the support plate 35, and the upper ends of a pair of operating rods 41 whose lower ends are fixed to the shaft are connected to the support plate 35 by connecting rods 42.
The handle shaft 40 protrudes outward to form a handle 40' at the end. A pair of gears 43 and 44 are fixed to each side of the drive shaft 34 and roller shaft 36, and a chain 45 is installed between the corresponding gears, and a gear 48 on one side of the reduction gear 47 installed on the bottom plate 31. A chain 50 is installed between gears 49 fixed to the other side of the drive shaft. Note that this speed reduction device slows down the rotation of the second motor 46.

Next, a drive shaft 51 is installed horizontally on the upper front side of the seat 33, and the upper ends of a pair of support plates 52 are swingably attached to both sides of the shaft, and the front pine surge roller 37' is rotated at the end of the support plates. A freely mounted front pine surge roller shaft 53 is supported, and the support plate and a pair of operating rods 55 whose lower ends are fixed to a handle shaft 54 horizontally installed at the lower stage are connected by a connecting rod 56, and the handle shafts extend outward. A projecting handle 54' is formed.
Gears 57 and 58 are fixed to both sides of the drive shaft 51 and roller shaft 53, respectively, and a chain 59 is installed between the corresponding gears to connect the gear 60 on the other side of the reduction gear 47 and the other side of the drive shaft 51. stuck gear 6
A chain 62 is installed between the two.

(Function) When you sit on the seat 33 and rotate the first motor M by operating a switch (not shown), the chain 23
The drive shaft 2 rotates via the gear 24, and the rotation of the shaft causes the rotation shaft 3 to rotate via the chain 7. Since the middle stage pine surge roller shaft 8 is installed on the front side of this chain 7, the middle stage pine surge roller 10 is raised or lowered. At this time, limit switches 25 and 26 are installed at the upper and lower stages of the pine surge roller, so they come into contact with the pine surge roller shaft and operate, causing the motor to rotate forward and backward, so the middle stage pine surge roller 10 repeatedly moves up and down to the back of the human body. Pinesurge. When performing pine surge on the nape of the neck, operate the handle 18 to tilt the support plate 12 that supports the upper pine surge roller shaft 13 forward, and the upper pine surge roller 14 will protrude forward as shown by the imaginary line in FIG. Can perform pine surgery. These pine surge rollers are covered with cloth 63 as shown in FIG.
operates through.

When performing pine surgery on the lower body, use handle 4.
0' to raise the support plate 35 that supports the lower pine surge roller shaft 36 using the drive shaft 34 as a fulcrum, and then operate the handle 54' to raise the support plate 52 that supports the front pine surge roller shaft 53 horizontally. When the second motor 46 is rotated after the drive shaft 51 is expanded upward to the fulcrum position, the lower pine surge roller shaft 36 rotates at a reduced speed.
The front pine surge roller shaft 53 is rotated via the gears 57, 58 and the chain 59 by the drive shaft 51 which rotates at a reduced speed. Therefore, the lower pine surge roller 37 and the front pine surge roller 37'
The lower body is massaged through the covering cloths 64 and 65. As shown in FIG. 6, when the backrest part 1 is tilted backward and the leg rods 66 attached to the upper outer side of the part are erected, it becomes like a bed, and thus each of the above-mentioned pine surge rollers can be operated as a bed-type pine surge machine.
