Description

[Detailed Description of the Invention] The present invention relates to a pine surge machine for applying a pushing and massaging effect to the human body.

BACKGROUND ART A pine surge machine is already known in which a large number of rods are arranged side by side at intervals in order to apply acupressure-like pine surges to the back of the human body, and the rods are made to appear and retract from the back of the human body. However, the above-mentioned protruding and retracting rods in this type of conventional pine surge machine simply protrude and retract in a straight line and exert a pressing action to push up against the human body, so the range of the pressing action is small, and the massing action in the lateral direction is limited. Because there is no massage, it has the disadvantage that the massaging effect is smaller than that of the shiatsu massage performed by a pine surgeon.

The present invention improves the drawbacks of the conventional pressing pine surge device described above, and also provides a pine surge device that can smoothly move the pressing points from one side to the other on the back of the human body and perform a comfortable pressing and massaging action. This is what we provide.

The drawings showing the embodiments of the present invention will be explained in detail below. Figures 1 and 2 show the main parts of the typical structure of the device of the present invention, and are arranged at equal intervals on a frame 1. A plurality of bearings 2, 2 are fixed in parallel with each other, and a short shaft 3, 2 is attached to each bearing 2, 2.
3 is rotatably inserted so that both ends of each short shaft 3, 3 protrude to both sides of the bearings 2, 2, and wheels 4, 4 having the same number of teeth are attached to both ends of each short shaft 3, 3, respectively. When the carrier wheels 5, 5 are interposed between the adjacent wheels 4, 4, and one of the wheels 4, 4 is driven from the drive motor 6 via the reducer 7, each wheel 4, 4 are rotated all at once in the same direction. On the free end surface side of each of the wheels 4, 4, pin shafts 8, 8 are protruded at positions away from the rotational axes of the wheels 4, 4 (eccentric positions). 4
As shown in the figure, the base 11 of the crank 10 is fitted through the bearing 9, and each crank 10, 1
0 extend substantially in parallel in the same direction, and are slidably supported at the intermediate portion by spherical bearings 13, 13 disposed on the upper frame 12 of the main body of the device, and the tip portion 14 of each crank 10, 10 extends substantially parallel to the same direction. , 14 penetrate the upper plate 15 and protrude outward to form an end portion for pushing and massaging the human body. Further, as shown in FIG. 2, the base portion 11 of each of the cranks 10, 10 is fitted onto each of the wheels 4, 4 arranged in parallel in sequence with the rotation phase shifted, so that each crank 1
The tips of 0 and 10 are moved up and down (appears and retreats) one after another with a slight delay.

FIG. 5 shows an embodiment in which the wheels 4, 4 described above are constructed with sprocket wheels 4A, 4A of the same diameter, and each wheel 4A, 4A is rotated simultaneously in the same direction by a chain 20. The carrier wheels 5, 5 are not required in this embodiment.

In this way, the pine surge device in this invention is
A plurality of wheels 4, 4 are arranged in parallel in at least two rows in the main body of the device, each of which rotates in the same direction at the same time, and a wheel of the same length is arranged at an eccentric position on the end surface of each wheel 4, 4. The bases 11, 11 of the cranks 10, 10 are sequentially pivoted with their rotational phases shifted, and the tips 14, 14 of each crank 10, 10 are made to protrude outward from the device main body in a row, and each crank 10, 10 Since the intermediate portion of the wheels 4 is slidably supported by swingable spherical bearings 13, 13, when the wheels 4, 4 are rotated simultaneously in the same direction by an appropriate drive device, each wheel 4, 4 rotates in the same direction. The bases 11, 11 of the cranks 10, 10 are rotated to impart reciprocating motion to each crank 10, 10,
The tip portions 14, 14 can protrude and retract to exert a pushing and massaging action on the human body. Furthermore, since each crank 10, 10 is supported by a swingable spherical bearing 13, 13 at its intermediate portion, the tip end portions 14, 14 of each crank 10, 10 make a turning movement while protruding and retracting. , performs an arcuate pushing action from top to bottom or from bottom to top against a desired part of the human body, and the respective tips 14, 14 provide comfortable pressing and massaging in soft, strong, and weak directions, just like the fingertips of a pine surgeon. be effective. Furthermore, since the position of the pivot point of each crank 10, 10 to each wheel 4, 4, that is, the rotation phase, is sequentially shifted slightly, as can be understood from FIG. The pressing point of the device pulsates in a wave pattern against the human body, and by forming the tips 14, 14 into a spherical shape or a fingertip shape, it exerts a comfortable pressing and massaging effect over a wide range of the back of the human body. Therefore, if the pine surgery device according to the present invention is attached to the back of a chair-type pine surgery machine, or especially to the center of a bed-type pine surgery machine, it can be applied to the back of the human body in a sleeping state with a strong or weak pressure similar to that used by a shiatsu therapist as described above. A pine surge machine with an excellent pressing and massaging effect is obtained.
