Description

[Detailed description of the invention] The present invention relates to a pine surger.

An overview of the configuration of the conventional pine surge device used to perform pine surges on the back and neck of the human body is as follows.
A running body having a screw hole that engages with the feed screw is inserted into a feed screw extending in the length direction of the pine surge device rotated by a drive motor, and a finger pressure roller is attached to the rotating shaft of another drive motor provided on the running body. This configuration consists of connecting the feed screws and the top sheet on the top of the feed screw and the traveling body.

With such a configuration, the feed screw is rotated to cause the traveling body to reciprocate in the longitudinal direction of the feed screw, and the acupressure roller itself is rotated by a drive motor provided on the traveling body. Then, by the reciprocating movement of the traveling body (acupressure roller) and the rotation of the acupressure roller, pine surgery is performed on the back, neck, etc. of a human body lying on the top sheet.

However, in the conventional pine surge device as described above, in addition to the drive motor for moving the acupressure roller (rotating the feed screw), a drive motor for rotating the acupressure roller itself is required, which increases the manufacturing cost. There was a drawback that it took a while. In addition, since the drive of each drive motor must be operated separately, handling becomes troublesome.

In order to solve the above-mentioned drawbacks of the conventional pine surge device, in a patent application filed at the same time as the present application, the applicant of the present application has decided to use only a drive motor that rotates a feed screw, and uses the rotation of the feed screw to move the traveling body back and forth. We proposed a pine surge device that can both move and rotate the acupressure roller. However, in the newly proposed pine surge device mentioned above, during the reciprocating movement of the traveling body, the rotation caused by the rotation of the feed screw of the acupressure roller and the rotation caused by moving on the feed screw interfere with each other, and the rotation of the acupressure roller stops. Therefore, there is a problem in that the pine surge effect due to the rotation of the acupressure roller cannot be obtained, that is, the pine surge effect due to the movement and rotation of the acupressure roller cannot be performed at the same time.

Therefore, in the above-mentioned pine surge device, when pine surge is performed by rotating the acupressure roller, the movement of the traveling body is stopped by the clutch mechanism.

The present invention has been made in view of the above-mentioned problems, and its purpose is to move and rotate the acupressure roller by rotating a feed screw using a single drive motor, thereby reducing costs. An object of the present invention is to provide a pine surge device which aims to reduce the amount of pressure and improve operability, and which can obtain a pine surge effect accompanying the rotation of the shiatsu roller itself even while the shiatsu roller is moving.

is rotatably provided, and the bell 1 on the shaft 24 is rotatably provided.
~Belt pulley 29 connected to wheel 25 via bell 1-28
is pivoted. The drive shaft 27 and the acupressure roller 8 are rotated by the rotation of the t-arm wheel 23 being transmitted via the belt 28.

Next, the operation of the pine surge device 1 configured as described above will be explained.

When the user 9 lying down on the top sheet 2 operates a predetermined operation switch (not shown) provided on the pine surge device 1, the motor is driven to rotate the feed gear 3 and the electromagnetic solenoid 16 is activated. Energize the clutch lever
When the hook portions 18A of No. 18 are locked with the locking protrusions 15A of the rotary nuts 1 to 15 within the cover 13, the rotation of the rotary nut 15 is stopped by the hook portions 18A (that is, the rotary nut 15 is connected to the housing 12 and the cover). 13). As a result, if the feed screw 3 continues to rotate, the rotary nut 15 moves along the feed screw 3 along with the housing 12 and the cover 13 in one direction along its length.

As the traveling body 7 moves, the acupressure roller 8 supported by the drive shaft 27 moves while coming into pressure contact with the back of the user 9, so that the acupressure roller 8 performs pine surge.

〔At that time, the planetary gear 2 meshing with the feed screw 3
1 moves on the feed screw 3 together with the housing 12, so as it moves, it rotates in the same direction as the moving direction, and also rotates in the opposite direction to cancel the rotation in the above moving direction due to the rotation of the feed screw 3. try to. However, due to the fact that the planetary gear 21 is rotatably held by a bearing 22 within the housing 12 and the rotational force in the opposite direction generated as the feed screw 3 rotates, the meshing state between the planet gear 21 and the feed screw 3 is The planetary gear 21 and frame 20° worm gear 19 are required to be strong.
is integrated with the feed screw 3 and is attached to the housing 1 together with the feed screw 3.
Rotates within 2. Therefore, the planetary gear 21 does not rotate in the opposite direction due to the rotation of the feed screw 3, and the planetary gear 21, frame 20. The worm gear 19 moves over the feed screw 3 together with the housing 12 and is attached to the feed screw 3 within the housing 12.
It will rotate with. As a result, worm gear 2
0 rotation is transmitted to the wormwheel 23 that is pivotally supported by the housing 12, and the wormwheel 23
The rotation is transmitted to the belt pulley 29 via the belt 28, and the acupressure roller 8 rotates. And this acupressure roller 8
Another pine surge is performed by the rotation of .

As described above, effective pine surge is achieved by the movement and rotation of the acupressure roller 8.

Now, when the electromagnetic solenoid 16 is energized by operating the operation switch and the hook portion 18A of the clutch lever 18 is released from the locking protrusion 15A of the rotary nut 15, the rotary nut 15 locks the feed screw 3 inside the cover 13.
As a result, the movement of the housing 12, that is, the traveling body 7, stops.

At this time, due to the above-mentioned reason, the planetary gear 21 and the frame 2
0. Since the worm gear 19 rotates together with the feed screw 3, the finger pressure roller 8 continues to rotate. Therefore, in this case, if the traveling body 7 is stopped at a desired position on the body of the user 9, intensive pine surgery can be performed only by rotating the acupressure roller 8.

As is clear from the above explanation, according to the pine surge device according to the embodiment of the present invention, the overall mulch is achieved by moving and rotating the finger pressure roller 8 by operating the clutch lever 18.
It is possible to select either the intensive pine surge using only the rotation of the finger pressure roller 8 or the rotation of the acupressure roller 8 as necessary.

Furthermore, in the pine surge device 1 according to the above-described embodiment, a slope portion 10△ whose height is gradually increased as shown in FIG. is formed.

Furthermore, the acupressure roller 8 provided on the traveling body 7 is supported by a drive shaft 27 via a connecting leg 26 whose one end is rotatably supported by a shaft 24 fitted into a bearing portion 12B of the housing 12. ing. Therefore, as shown in FIG. 7, when the guide roller 11 of the acupressure roller 8 rolls on the guide rail 10 corresponding to the back part of the human body due to the movement of the traveling body 7, the connecting leg 26 is in a sufficiently inclined state. If the distance between the guide rail 10 and the feed screw 3 is determined as shown in FIG.
runs onto the inclined part 10A of the guide rail 10 (the seventh
(The part indicated by the dotted line in the figure). Therefore, with the above structure, the acupressure roller 8 can be moved at the inclined portion 10 of the guide rail 10.
Since this moves up and down, it is possible to effectively perform pine surgery on the neck, which is more depressed than the back of the human body.

As described above, according to the present invention, since the acupressure roller can be moved and rotated simultaneously by a single drive motor, extremely effective pine surgery can be performed and manufacturing costs can be reduced. In addition, either the movement and rotation of the acupressure roller or only the rotation of the acupressure roller can be controlled by the clutch lever.
Since it can be selected arbitrarily and easily by the operation, it is extremely practical and easy to handle.
