Description

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

Conventionally, a pine surgery device for pine surgery on the back and neck of a human body has been constructed by inserting a running body having a threaded hole that engages with the feed screw into a feed screw rotated by a motor, and also inserting a running body having a screw hole that engages with the feed screw into the feed screw rotated by a motor. There is one in which an acupressure roller is attached to a top sheet and a feed screw and a top sheet that covers the top surface of the traveling body are installed. With this configuration, the feed screw is rotated to cause the acupressure roller to reciprocate along with the traveling body in the longitudinal direction of the feed screw, and the motor provided on the traveling body is driven to cause the acupressure roller itself to perform eccentric rotation, etc. . By reciprocating and rotating the acupressure roller, the back, neck, etc. of a human body lying on the top sheet are massaged.

However, the conventional pine surge device as described above has the following drawbacks.

To move the acupressure roller (reciprocating motion),
That is, in addition to the motor for rotating the feed screw, a motor for rotating the acupressure roller itself is required, which increases manufacturing costs. Furthermore, since the rotation of the feed screw and the rotation of the acupressure roller itself are performed by separate drive motors, each drive must be operated separately, making handling operations cumbersome.

The present invention was made in view of the problems of the conventional pine surge device as described above, and its purpose is to move and rotate the acupressure roller using a single drive motor, thereby improving manufacturing efficiency. The purpose is to propose a pine surge device that is inexpensive and easy to handle and operate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings showing a preferred embodiment.

In FIG. 1, 1 is a pine surge device, and 2
is the top sheet. 3 is a feed screw installed at the bottom of the top sheet 2, and both ends are connected to the pine surge device 1.
It is pivotally supported by bearings 4' and 5' provided on support plates 4 and 5 at the front and rear ends. This feed screw 3
is connected to a motor (not shown) provided in the pine surge device 1 at a pulley 6 via a timing belt or the like, and rotates by transmitting the rotation of the motor.

Reference numeral 7 denotes a running body fitted to the feed screw 3, which reciprocates in the longitudinal direction of the feed screw 3 as the feed screw 3 rotates due to a configuration described later. Reference numeral 8 denotes an acupressure roller provided on the traveling body 7, and is positioned so as to come into pressure contact with the user 9 lying on the top sheet 2 via the top sheet 2. Reference numeral 10 denotes guide rails for the traveling body 7 which are installed parallel to the feed screw 3 between the support plates 4 and 5, and two guide rails are installed at a predetermined interval as shown in FIG.
The running body 7 has running rollers 11 provided on both sides of the lower part.
A protrusion 12 provided at the lower end of the traveling body 7 is placed between the guide rails 10 to stop the rotation of the traveling body 7 itself due to the feed screw 3. . Also, 13
is a limit switch attached to the side of the guide rail 10 at a predetermined interval, and controls the motor so that the traveling body 7 moves back and forth within the predetermined interval.

The outline of the configuration of the pine surge device 1 according to an embodiment of the present invention is as described above. Hereinafter, the configuration of the traveling body 7, which is the main part of the present invention, will be explained in detail using FIGS. 2 to 5.

14 and 15 are housings of the traveling body 7;
They are fixed to each other and become one body. As shown in FIG. 3, the housings 14 and 15 are fitted onto the feed screw 3 so as to be movable in its longitudinal direction. 1
Reference numeral 6 denotes a helical gear positioned in the housing 14 so as to mesh with the feed screw 3. This helical gear 16 is fixed to a rotating shaft 17 that is pivotally supported by the housing 14. Then, feed screw 3
When it rotates, the rotation is transmitted by the helical gear 16, and the rotating shaft 17 rotates. Furthermore, the acupressure roller 8 is attached to both ends of this rotating shaft 17 and rotates together with the rotating shaft 17.

18 is a rotary nut housed within the housing 15. The structure of this rotary nut 18 is that, as shown in FIG. 4, a locking nut 19 has locking protrusions 20 at approximately 90° intervals on its outer periphery, and auxiliary nuts 21 having a slightly larger diameter than the locking nut 19 are provided on both sides of the locking nut 19. It is formed into a triple structure that is fixed as one piece. Further, a threaded hole 22 is provided at the center of the auxiliary nut 21 and the locking nut 19 so as to communicate with each other, and the rotary nut 18 is meshed and fitted to the feed screw 3 through this threaded hole 22. Here, the housing 15 accommodates and holds the rotary nut 18 in a state where the rotary nut 18 can freely rotate on the feed screw 3. Further, the internal width in the direction of the feed screw 3 is approximately equal to the thickness of the rotary nut 18.

23 is an electromagnetic solenoid installed on the side of the housing 15, and 24 is a plunger that moves up and down when the electromagnetic solenoid 23 is excited. Prasia 24
At the tip of the clutch lever 25, an end portion of a clutch lever 25 having one end bent into a hook shape is rotatably supported. Further, a substantially central portion of the clutch lever 25 is rotatably supported by a support portion 26 provided on the housing 15 (FIG. 5). In this state, the hook portion 25' at the tip of the clutch lever 25 is positioned so as to be insertable into the housing 15 through the notch hole 27 provided on the upper surface of the housing 15. With this structure, if the electromagnetic solenoid 23 is energized and the plunger 24 is made to protrude upward, the hook portion 2 of the clutch lever 25
5' moves downward using the support part 26 as a fulcrum and is inserted into the housing 15 through the notch hole 27, and when the plunger 24 is pulled downward, the hook part 2
5' moves upward and substantially comes out of the housing 15.

Next, pine surge device 1 configured as above
The operation will be explained.

First, the user 9 lying down on the top sheet 2 operates a predetermined operation switch (not shown) provided on the pine surger 1 to drive the motor and rotate the feed screw 3. Next, when the electromagnetic solenoid 23 is energized by operating the operating switch in the same manner and the hook portion 25' of the clutch lever 25 is lowered and inserted into the housing 15, the hook portion 25' is lowered and inserted into the housing 15.
As a result of the tip of the rotary nut 18 coming into contact with the locking protrusion 20 on the locking nut 19 of the rotary nut 18, the rotation of the rotary nut 18 is stopped (that is, the rotary nut 18 is integrated with the housing 15). Therefore, if the feed screw 3 continues to rotate in this state, the rotary nut 18 will move away from the housing 14.
and 15 on the feed screw 3 in either one of its longitudinal directions. As a result, the housing 14
Since the acupressure roller 8 supported by the rotating shaft 17 moves while being in pressure contact with the back of the user 9, the acupressure roller 8 performs pine surge. In this case, it goes without saying that when the traveling body 7 moves to one limit switch 13, the direction of rotation of the feed screw 3 changes and moves in the opposite direction, thereby reciprocating between the limit switches 13.

Now, when the user 9 operates the operation switch to energize the electromagnetic solenoid 23 and raise the hook portion 25' of the clutch lever 25 to release the locking protrusion 20, the rotary nut 18 is moved into the housing 15 by the feed screw. 3, the movement of the housings 14 and 15, that is, the traveling body 7, stops.
At this time, since the helical gear 16 in the housing 14 is rotating as the feed screw 3 rotates, the acupressure roller continues to rotate. Therefore, if the acupressure roller 8 is shaped like an ellipse or remains circular and is attached to the rotating shaft 17 at a position offset from the center, the acupressure roller 8 will perform a movement that changes vertically (eccentric movement) as it rotates. , Shiatsu roller 8
This means that pine surgery can be performed using a chisel. In that case, if the traveling body 7 is stopped at a position desired by the human body, it becomes possible to perform focused pine surgery using the acupressure roller 8. Note that the acupressure roller 8 while the traveling body 7 is moving is connected to the helical gear 1 by the feed screw 3.
6 and the rotation of the helical gear 16 on the feed screw 3 due to the movement of the traveling body 7 cancel each other out, so that the helical gear 16 does not rotate.

As can be seen from the above description, the pine surge device of this embodiment controls the drive of the electromagnetic solenoid 23 to perform either pine surge due to the reciprocating movement of the acupressure roller 8 or pine surge due to the rotation of the acupressure roller 8, as necessary. It is a choice.

As described above, according to the present invention, since the acupressure roller can be moved and rotated by one motor, manufacturing costs can be significantly reduced without impairing functionality. In addition, since it is possible to arbitrarily select either movement or rotation of the acupressure roller by operating the clutch lever, it is extremely practical and easy to handle.
