Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a pine surge device, more specifically, a shiatsu-style massage with a variety of strength changes by giving rise and fall to the movement locus of the oscillating massaging action of an inclined massaging wheel fitted to an inclined eccentric cam. The present invention relates to a pine surge device that can perform the following functions.

A wide variety of massage machines are already known that reciprocate within a backrest, stop at a desired position, and apply massage to a part of the human body by swinging a massage wheel. However, the tilted kneading wheels in conventional pine surge machines of this type merely repeat a simple oval motion in plan view, rocking in the left and right directions while moving back and forth in the front and back directions based on the rotation of the tilted eccentric cam. However, there was little change in the pressing force against the human body, and the massaging effect was monotonous.

The present invention improves the monotonous kneading action caused by the oscillation of the inclined kneading wheel, and displaces the supporting part of the kneading wheel in the front-rear direction during the kneading action caused by the oscillation of the kneading wheel, thereby creating a pine surge on the working surface of the kneading wheel. To provide a pine surge device capable of performing a pressing pine surge with a wide variety of strength changes, such as acupressure action with a fingertip of a master.

Embodiments of the present invention will be described below based on drawings showing embodiments of the present invention. FIGS. 1 and 2 are a front view and a side view schematically showing a reciprocating device section, in which 1 is a backrest main body, 2 is a backrest main body;
8.8 is a massage ring installed in the device 2 and located along the inner surface of the back seat 4 of the main body 1; 5 is the base of the device 2; 6 is a screw shaft for moving the device section 2 upward and downward, and as is well known, the direction of rotation of the device section 2 is controlled by forward and reverse rotation of a motor (not shown). It is reciprocated by means of a shaft 6 and a female screw member 7 of the base frame 5 screwed onto the screw shaft 6.

The present invention provides such a pine surge machine in which, as shown in FIGS. 2 and 8, in parallel with the above-mentioned screw shaft 6,
Preferably, one spline type subshaft 8 is disposed at the front position of the screw shaft 6, and the subshaft 8 is provided with a spline type subshaft 8.
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 above-mentioned kneader @B, 3, which was inserted into the device section 2, was rotatably fitted on the horizontal shaft 10 as shown in the figure 811iDl. In n An elliptical eccentric cam 13.13 is fixed to both ends of the shaft 10 in contact with the front surface of the guide rail 12.12 and rotated together with the horizontal shaft 10.
The cam bodies 11 and 11 are configured to be rotated individually by the worm 9 at different rotational speeds.

For example, as shown in the figure, a gear 1 meshing with the worm 9
4 is meshed with a carrier gear 16 having pinions 15.15 on both sides, and a gear 17 fixed to the horizontal shaft 10 is meshed with the carrier gear 16, and with pinions 15.15 on both sides of the carrier gear 16. On the inside of each of the above-described oblique shoulders 110 and cam body 11.11,
Gear 18 provided integrally with force Ag1l+11.
18, and the carrier gear 1 is transferred from the worm 9 to the carrier gear 1.
6 via the horizontal IItl+lo and elliptical eccentric cams 18.13 and the pinion 15 on both sides of the carrier gear 16
．． The 4'A 44'nj'ε cam body 1 via L5
1.11 are configured to be actively rotated at different rotation speeds.

The above-mentioned screw shaft 6 and sub-shaft 8 are configured to be selectively driven by a motor via an arbitrary switching means. For example, as shown in FIG. 4, a clutch device t?
! 1120 is provided so that the rotation of the drive shaft 22 fixed to the pulley 21, which is transmitted from the motor, is transmitted to the screw shaft 6 or the subshaft 8 via the electromagnetic clutch 28. To explain the clutch mechanism 20 shown in FIG. 4 in more detail, the drive shaft 22 is of a spline type and is made of a non-magnetic material, and is rotatable by bearings 24 and 24 on an extension of the axis of the subshaft 8. is supported by This drive shaft 22 has a gear 27 that meshes with a gear 25 fixed to the adjacent screw shaft 6 and has engagement teeth 26 on the upper surface, and a gear 27 that is fixed to the lower end of the subshaft 8 and has engagement teeth 28 on the lower surface. between the drive shaft 22 and the holder 29 having a
It is movable in the axial direction and has engaging teeth 80°8 on the upper and lower end surfaces.
A drum-shaped movable iron core 31 with 0 is fitted, and a fixed iron core 32 located in the central recess of the movable iron core 81 is fitted around the outer periphery of the movable iron core 81, and electromagnetic coils 88, 84 are installed above and below the fixed iron core 32. The electromagnetic clutch 20 is configured by arranging a U-shaped yoke B5, and when the upper electromagnetic coil 34 is excited, the movable iron core 82 moves downward and engages with the gear 27 to stop the rotation of the motor. When the lower electromagnetic coil 34 is excited, the movable iron core 31 moves upward and engages the boulder 29, so that the rotation of the motor is transmitted to the subshaft 8. . 86. 86 is a restoring spring for holding the movable iron core 31 at an intermediate position in the non-energized spoon.

As described above, the pine surge machine of the present invention is a pine surge machine in which the device section 2 having at least one pair of left and right kneading wheels 3, 3 is reciprocated by controlling the rotational direction of the screw shaft 6. A sub-shaft 8 is disposed parallel to the screw shaft 6 so that either one of the screw shaft 6 and the sub-shaft 8 can be selectively rotated. A worm 9 that rotates with the shaft 8 and is movable together with the device section 2 is attached to the bottom, and the pair of kneading wheels 3, 3 installed in the device section 2 are rotatably attached to the horizontal shaft 10 of the f& device section 2. It is rotatably mounted on the outer periphery of the fitted inclined eccentric cam body 11.11, and the outer periphery is supported in contact with the front surface of a guide rail 12.12 extending in the vertical direction at both ends of the horizontal shaft 1o. An elliptical eccentric cam 18 rotating with the horizontal axis 1o.
18 is fixed, and the worm 9 is configured to actively drive the horizontal shaft lO and the inclined eccentric cam body 11.11 at different rotational speeds through a suitable gear train when the subshaft 8 rotates. With this configuration, when a motor (not shown) is started and, for example, a switch (not shown) for excitation of the electromagnetic coil 38 of the clutch means 2o is operated, the movable iron core 31 moves downward. The engaging tooth 3o of the movable iron core 31 engages with the engaging tooth 26 of the gear 27, whereby the rotation of the motor is transmitted to the screw shaft 6 and the device section 2
When the motor is moved, the rotation direction of the motor is controlled by the alternating operation of the limit switches 2 disposed above and below inside the backrest main body 1, so that the device section 2 moves along the guide rails 12, 12. The massage wheel 3 moves back and forth on the back of the human body.
゛、Carry out the sasurimatsusage due to the 3rd transfer. During this time, the elliptical eccentric cam 18.18 mentioned above is connected to the guide rail 12.
, 12 without rolling. When the rice flour 3, 3 reaches the desired position, the electromagnetic coil 38 is de-energized by operating a switch, and the movable iron core 31
is restored to the inoperative intermediate position by the spring 36 and disengaged, the screw shaft 6 is stopped, and the device section 2 is stopped at the desired position. Next, when another switch is operated to excite the lower electromagnetic coil 34, the movable iron core 31 is moved upward, the rotation of the motor is transmitted to the subshaft 8, the worm 9 of the subshaft 8 is rotated, and the worm is rotated. 9 rotates the horizontal shaft 1o and the inclined eccentric cam body 11.11 at different rotational speeds via a gear train. As a result, the kneading wheels 3, 3 are swung in the left-right direction while their working surfaces are moved in and out in the direction of the arrow a in FIG.
．． The horizontal shaft 10 rotates on the front surface of the gear 1+.
A rocking motion in the direction indicated by the arrow is added using the shaft 37 as a fulcrum, and this rocking motion in the front-rear direction of the horizontal shaft 1o and the rocking protrusion and retraction motion by the inclined eccentric cam body 11.11 are combined to cause the massaging wheel 3, 3, a motion in which the amount of movement of the protrusion and retraction changes slightly is transmitted.

For example, when the rotational speed ratio of the inclined eccentric cam body 11.11 and the elliptical eccentric cam 18 is set to 1:2, the displacement of the horizontal shaft 10 during one rotation of the inclined eccentric cam body 11.11 The locus and the accompanying locus of appearance and retrieval of the working surfaces of the massage wheels 8, 8 are as shown in FIG.
During 0 or 1/4 rotation to 3/4 rotation, it maintains the forward position toward the backrest seat side, and after one rotation, it returns to the backward position, repeating the cycle, during which the working surface of the kneading wheel 3 moves in the left-right direction. Although it continues to move forward while moving, since the horizontal shaft 10 has moved backward when the inclined eccentric cam body 11.11 has rotated 172 times, the working surfaces of the kneading wheels 8, 8 temporarily and rapidly move backward slightly. However, a phenomenon occurs in which the vehicle moves forward again and then starts moving backward. That is, horizontal axis 1
0 is the solid line (A) in FIG. 6 due to the rotation of the elliptical eccentric cam 13.
), and the massage wheels 3, 3
The amount of protrusion and retraction of the working surface is due to the combination of the rotation of the inclined eccentric cam body 11.11 and the protrusion and retraction movement of the horizontal shaft 10, resulting in an M-shaped protrusion and retraction movement as shown by the solid line (B) in Figure 6. The swing locus of the working surfaces of the massaging wheels 3, 3 in the left-right direction is as shown in FIG. 7, and the turning locus in the vertical side direction is as shown in FIG. Therefore, a pressing action with a variety of strengths and weaknesses is achieved on the human body, and in particular, when the tilted eccentric cam body 11 rotates once and twice, the pressing force of the kneaded yuzu 3 becomes the strongest, and the horizontal shaft 10 rapidly retreats.・If set to move forward, it could not be achieved with conventional pine surge machines 2
A step pushing kneading action is performed, and the inclined eccentric cam body 11.
Combined with the oscillating motion of massaging 3 and 8 for each revolution of 11, it has the revolutionary effect of imparting a pleasant feeling to the human body, similar to acupressure performed by a pine surgeon.

In the above embodiment, the case where the rotational speed ratio of the horizontal shaft 10 and the inclined eccentric cam rest 11 was set to 2=1 was explained, but the rotational speed ratio between the two is not particularly limited; 1.5:1.1, 8:1, or 2.5:1
．． It goes without saying that similar effects can be obtained even with 8:1, etc., and the shape of the elliptical eccentric cam 13 and the mounting position of the horizontal shaft 10 are not necessarily specified in the illustrated manner, and the shape of the elliptical cam and the horizontal By appropriately setting the mounting position on the shaft, subtle changes can be made to the rocking movement of the massaging wheel.
