There is a pine serge machine that can be obtained, such as light rubbing mafusano et al.

DISCLOSURE OF THE INVENTION 1 The present invention provides a system in which a plurality of rollers are freely rotatably attached to the circumference of a rotating body that moves along a rail, and between the rotating body and a drive unit that rotates the rotating body. It is characterized by the provision of a switching means that disconnects the connection between the two and switches the rotating body between rotation and non-rotation, and by moving the rotating body while rotating, it is possible to By moving the acupressure massage without rotating the rotating body, we were able to transfer a specific roller while it was in contact with the back of the human body, making it possible to obtain a massage by rubbing the body.

The present invention will be described in detail below based on the illustrated embodiments.
The embodiment shown in FIGS. 3 to 3 is a recessed part of the back of the chair, and the chair has a pipe frame 1, a seat shoe/1/2, and a seat on both sides of the front of the back. Placed on the back 1-3, spatula placed on the top of the back
) 4. It consists of a back cover 5 located at the center of the front of the backrest at 7/3 inch 31Il, and the parts of the pipe frame 1 located on both sides of the back of the backrest have mutual openings. are fixed to opposing F-shaped rails 6, and a pipe 7 is attached to the back of the central part of the backrest.
Support plate 14 extending from frame 1. A feed screw 13 whose upper and lower ends are supported by +5 bearings is installed, and a pulley 16 attached to the lower end of the feed screw 13 is connected by a belt 18 to a pulley 22 of a motor 17 placed at the lower end of the back of the backrest. I'm nine months old. Further, a rack 7 is fixed to each of the interlocking ends of the pair of rails 6, and limit switches 21 and 21 are attached to the upper and lower ends of one of the rails 6, respectively.

A rotating body 9, which is a member that performs Massano motion, and a roller 10 attached to the circumference of this rotating body 9 are connected to a drive shaft 8.
is attached to. This drive shaft 8 has rollers 20 attached to both ends that move within the rail 6, and a pinion 19 that meshes with the rack 7 is fixed. It passes through an elongated hole 12m long in the front-rear direction of the backrest having a shape dL8 in the body 12. When the feed screw 13 is rotated, the moving body 12 moves up and down. At this time, the drive shaft 8 that moves up and down with the moving body 12 moves the rollers 20 at both ends of the rail 6, and Mobile object 1
2, it can move up and down along the rail 6, which is bent to follow the shape of the back of the human body, and the pinions 19 at both ends are engaged with the rack 7. , which rotates as it moves up and down.

Now, a pair of rotating bodies 9 are attached to the drive shaft 8 with a movable body 12 in between, and each rotating body 9 has two
It is a three-pronged thing with three legs protruding radially from the tora, which is made of two plates.
4, the roller 1 () is attached, and a sleeve 23 that connects both rotating bodies 9 is inserted into the inner periphery. l! It against Kintsumugi 8
It is free. Moreover, on one side of one rotating body 9,
As shown in FIG. 3, an electromagnet containing a coil 23 is fixed within the yoke 27. On the other hand, a clutch plate 26 is fixed to the drive shaft 8 via a rack body 25.
Further, a pin 30 is incorporated into the clutch plate 26 and is urged in the projecting direction by a spring 29. Here, the clutch plate 26 and the yoke 27 face each other, and their opposing surfaces are formed with meshing teeth that mesh with each other to form the meshing clutch 11. When the fill 28 is energized and excited, The yoke 27 and the clutch plate 26 are engaged, and the rotation of the drive shaft 8 is transmitted to the rotating body 8.The yoke is pushed by the pin 30 that protrudes under the force of a spring, and the yoke is When the clutch plate 27 and the clutch plate 26 are separated, the rotation of the drive shaft 8 is no longer caused by the rotating body 9.

When the motor 17 is rotated with the dog clutch 11 connected, the drive shaft 8 moves up and down together with the movable body 12 due to the drive by the feed gear 13, and along with this up and down movement, the drive shaft A rotating body 9 rotates together with the rotating body 9, and a roller 10 attached to the tip of each leg protruding from the rotating body 9 moves the back of the human body through the back cover 5 as shown in FIG. It moves up and down while sequentially replacing the pressing roller 1O, that is, while intermittently applying finger pressure to the back of the human body. Also, meshing clutch 1
When the motor 17 is rotated with the roller 1 disconnected, the rotation of the drive shaft 8 is not transmitted to the rotating body 9, so the rotating body 9 is rotated by one of the three rollers 10, as shown in FIG. The two rollers 10 are moved while being rolled so as to rub the back of the human body through the back cover 5. When the drive shaft 8 reaches the upper and lower ends of the rail 6, this is detected by the limits or slots 21, 21, and the direction of rotation of the motor 17 is reversed.

4 to 6 show embodiments of the pond, in which the rotating body 9 is directly fixed to the drive shaft 8, and a dog clutch as shown in the previous embodiment is not provided.
Whether or not the rotating body 9 is rotated along with its vertical movement is controlled by whether or not a pinion 19 attached to the drive shaft 8 is engaged with the rack 7. Here, the pinion 19 is attached to the drive shaft 8 by spline portions 33 provided at both ends of the drive shaft 8 so as to be able to freely slide in the axial direction and to transmit rotation. A pin 34 biased by a spring 35 provided on each spline portion 33 elastically locks the pinion 19 at a point 2 (xi). If you move it to the side, pinion 19
is engaged with rack 7, and pinion 1 is engaged in the opposite direction.
If the pinion 19 is moved, the pinion 19 will not engage with the rack 7, and therefore, when the drive shaft 8 is moved up or down, the drive shaft 8 will not rotate.

The means for moving the pinion 19 is constituted by guide plates 31 and 32 fixed to the upper and lower ends of the rail 6. The idle plate 31 arranged at the upper end of the rail 6 moves the pinion 19 toward the center side as the drive shaft 8 moves upward, and removes the pinion 19 from the position where it engages with the rack 7. A guide plate 32 provided at the lower end of the pinion 19 guides the pinion 19 toward the end of the drive shaft 8 as the drive shaft 8 moves downward, and guides the pinion 19 to a position where it engages with the rack 7. In other words, it is possible to perform switching without the need for a clutch.

However, in this lever pine serge machine, during upward movement, the rack 7 and pinion 19 engage, the drive shaft 8 rotates, and the rotating body 9 rotates accordingly.
This is to perform the pine surge in the state shown in the figure, and since the rank 7 and pinion 19 are not engaged during the downward movement, the pine surge in the state shown in FIG. 8 is performed.

When it is desired to obtain the pine surge shown in Fig. 7 during downward movement, or when it is desired to obtain the pine surge shown in Fig. 8 during upward movement, before the pinion 19 reaches the idle plate 31, 32, The rotation direction of the motor 17 may be reversed by operating a switch.

[Effects of the Invention] As described above, in the present invention, a plurality of rollers are attached to the circumference of a rotating body that moves along a rail, and a switching means for switching between rotation and non-rotation of the rotating body is provided. When the rotary body is rotated, acupressure pine surge can be obtained by the multiple rollers that revolve as the rotary body rotates, and when the rotary body is not rotated, at that time, it can be applied to the back of the human body. Since the rollers in contact roll on the back of the human body, a pine surge can be obtained.
