Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pine surgery device, specifically a pine surgery roller that reciprocates to perform pine surgery on the back of a human body, and further stops the movement of the roller when desired, and applies strength or weakness to the back of the human body at an arbitrary position. This invention relates to a pine surge device that can perform a variety of acupressure-like pine surges.

Various types of pine surge devices are already known in which one or two pairs of rollers are reciprocated within the backrest to perform a pine surge effect while making contact with the back of the human body. The pine surge effect is relatively monotonous and has the disadvantage that a strong and effective pine surge effect cannot be obtained locally. From this, recently, in addition to the rubbing pine surge action by the reciprocating motion of the pine surge roller, it is now possible to perform pressing pine surge on a desired part of the human body by swinging the pine surge roller while the movement of the pine surge roller is stopped. The pine surge device constructed as described above has come to be used favorably, but the present invention further improves it, and enables pine surge by the reciprocating movement of the pine surge roller, and for local positioning when the pine surge roller is stopped at a desired position. The object of the present invention is to provide a pine surgery device that can perform a pushing action with a wide variety of strengths, similar to the acupressure action of a pine surgeon's fingertips.

The drawings showing the embodiments of the present invention will be explained below. FIGS. 1 and 2 are a front view and a side view showing an outline of the entire device, in which 1 is a backrest main body, and 2 is an inside of the main body. A device section mounted so as to be reciprocally movable, 3, 3 is a pine surge roller mounted on the device section 2 and located along the inner surface of the backrest sheet 4 of the main body 1, 5 is a base frame of the device section 2, and 6 is a device The device section 2 is a screw shaft for vertically moving the section 2, and the device section 2 includes a screw shaft 6 and a screw shaft 6 that are controlled by forward and reverse rotation of a motor, as is well known.

It is moved back and forth by means of. In such a pine surge machine, the present invention provides a spline type subshaft 8 in parallel with the screw shaft 6, preferably at a position in front of the screw shaft 6, as shown in FIGS. 2 and 3. At the same time, the subshaft 8 is provided with a
A worm 9 that rotates with the base frame 5 of the device section 2 and can move together with the base frame 5 of the device section 2 is fitted. On the other hand, the pine surge roller 3 in the device section 2

12, and fixed to both ends of the horizontal shaft 10 are eccentric cams 14, 14 rotatably fitted in ring bodies 13, 13 that are rotatable along the guide rails 12, 12, The horizontal shaft 10 and the eccentric cams 14, 14 are configured to be individually rotationally transmitted from the worm 9 at different rotational speeds. For example, as shown in the figure, the worm 9
There are small gears 16, 16 on both sides of the gear 15 that meshes with the
A gear 18 fixed to the horizontal shaft 10 is engaged with a carrier gear 17 having a
The eccentric cam body 1 described above is meshed with the small gears 16, 16 on both sides of the carrier gear 17.
Gears 19 and 19 provided inside the worms 1 and 11 are engaged with each other so that the worm 9 positively rotates the horizontal shaft 10 and the eccentric cam body 11 at different rotation speeds.

The above-mentioned screw shaft 6 and subshaft 8 are constructed so that either one is selectively driven by a motor via a clutch means. That is, for example, as shown in FIG.
The movable part 2 of the clutch is attached to a shaft 21 driven through the
2 and connect the movable part 22 to the electromagnetic solenoid 23.
The transmission gear 25 to the screw shaft 6 is engaged with the lever 24 which rotates in angle with the on/off operation of the clutch, and the transmission gear 25 to the screw shaft 6 is attached to one of the engagement action portions 22A of the movable portion 22 of the clutch, and the other engagement action is Transmission gears 26 for the subshaft 8 are loosely fitted to the shaft 21 on the side of the part 22B, and the movable part 22 is screwed by turning on and off the electromagnetic solenoid 23 by operating a switch (not shown). Transmission gear 25 to shaft 6 or countershaft 8
The shaft 21 is engaged with a transmission gear 26 to transmit the rotation of the shaft 21 to either one.

As described above, the pine surge machine of the present invention is a pine surge machine in which the device section 2 equipped with at least one pair of pine surge rollers 3, 3 is reciprocated by controlling the rotational direction of the screw shaft 6. A sub-shaft 8 is disposed parallel to the shaft 6 so that either one of the screw shaft 6 and the sub-shaft 8 can be selectively rotated. An eccentric cam body 11 is fitted with a worm 9 that rotates together with the subshaft 8 and is movable together with the device section 2, and the pine surge rollers 3, 3 provided in the device section 2 are rotatably fitted on the horizontal shaft 10. . Eccentric cams 14, 14 are fixed, and when the countershaft 8 rotates, the worm 9 is connected to the horizontal shaft and the eccentric cam bodies 11, 11 through an appropriate gear train.
and are actively driven at different rotational speeds, for example, when the electromagnetic solenoid 23 is in a non-energized state, that is, when the movable part 22 of the clutch is engaged with the transmission gear 25 to the screw shaft 6. When the start switch (not shown) of the motor M is turned on in this state, the screw shaft 6 is rotated and the device section 2 is moved as in the conventional case, and the limit switches disposed above and below inside the main body 1 are operated alternately. The rotation direction of the motor M is converted and controlled by the device section 2.
moves back and forth along the guide rails 12, 12,
A pine surge is performed on the back of the human body using pine surge rollers 3, 3. When the pine surge rollers 3, 3 reach the desired positions, the switch is operated to excite the electromagnetic solenoid 23 and displace the movable part 22 of the clutch toward the transmission gear 26 to the subshaft 8. 6 is stopped, the subshaft 8 is rotated, and the movement of the device section 2 is stopped, and the worm 9 of the subshaft 8 rotates the horizontal shaft 10 and the eccentric cam body 11 through the gear train by the worm 9 of the subshaft 8.
11 are rotated at different rotational speeds. As a result, the pine surge rollers 3, 3 are rotated by the rotation of the eccentric cam bodies 11, 11, while their working surfaces are moved in and out in the direction of the arrow a in FIG.
A rocking motion in the direction of arrow b is added with the fulcrum at
The amplitudes of the eccentric cam body 11 and the eccentric cam 14 interfere, and the amount of movement of the pine surge roller 3 in the front-rear direction changes slightly. For example, when the rotation ratio between the eccentric cam body 11 and the eccentric cam 14 is 1:2, the eccentric cam body A delay occurs in the rotation of the eccentric cam 11, and during this time a phase shift occurs between the amplitude A of the eccentric cam body 11 and the amplitude B of the eccentric cam 14, and the composite amplitude C of both changes slightly. That is, eccentric cam 1
When the maximum protrusion position of the eccentric cam body 11 is set advanced by 45 degrees with respect to the maximum protrusion action position of 4, Fig. A is shown, and when the maximum protrusion positions of both eccentric cams are set to match, Fig. B is shown. When the maximum protrusion position of the eccentric cam body 11 is set delayed by 45 degrees, 90 degrees, and 135 degrees, the resultant amplitude C is as shown in diagrams C, D, and E. This composite amplitude C can be further changed by appropriately selecting the rotation ratio between the eccentric cam body 11 and the eccentric cam 14.

Therefore, according to the present invention, unlike the conventional regular pressing action, the working surfaces of the pine surgical rollers 3, 3 irregularly change shallowness and depth with respect to the human body, and the pressure is similar to acupressure by a pine surgeon. The effect is achieved and a comfortable and effective pine surge effect can be obtained.
