Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massaging device which oscillates a torso of a body by moving it back and forth while lying on the floor.

[0002]

2. Description of the Related Art The physical function is improved by performing moderate exercise. In particular, when exercise is exerted on the abdominal viscera, the visceral functions are activated, and at the same time, the amount of oxygen absorbed by the body is increased and health is promoted. For the purpose of performing such an exercise, a massager that reciprocates the ankle left and right has been conventionally used. As shown in FIG. 2, this massager is provided on the main body case 1 having a height of about 100 to 200 mm, and is installed on the main body case 1 and reciprocates left and right with an amplitude of about 20 to 40 mm. It consists of a pedestal 2 and a supine on the floor and rests the ankle on the pedestal 2.
By reciprocating left and right at a speed of about 150 times, the legs reciprocate left and right, the internal functions are activated, blood circulation is improved, and the amount of oxygen absorbed by the body is large. And improve your health. In addition, at the same time, since the motion of bending the spine to the left and right is added, the posture is improved and the effect is further increased. Inside the main body case 1, two slide shafts 31 and 32 which are vertically parallel are provided, and a slide plate 33 is fitted therein. Further, although not shown, a drive motor is provided inside the main body case 1, and its rotary shaft and the slide plate 33 are connected via a crank mechanism, so that the rotary motion of the rotary shaft is changed in the left-right direction. It is transmitted to the slide plate 33 in place of the reciprocating motion of (1) and is reciprocated left and right along the slide shafts 31, 32. The upper part of the slide plate 33 is projected to the upper surface of the main body case 1, and the leg stand 2 is attached thereto. By reciprocating the slide plate 33, the leg stand 2 reciprocates integrally with this. It is configured to exercise.

As described above, in the conventional massage device, the leg 2 is reciprocated left and right by the crank mechanism. Therefore, the speed at each position when the leg base 2 moves is specified in advance, and the movement is limited to the speed distribution approximate to the sine curve. There is a problem that the effect cannot be lifted. When massaging, a relatively large resistance acts on the reciprocating motion of the foot stand 2, but this massaging device
Since it is used indoors, it is necessary to reduce the weight of the body, so that the respective drive members are delicately formed. Therefore, it is difficult for the driving member and the like to operate smoothly because of difficulty. Moreover, when the pedestal 2 is changed from the forward path to the return path, the force of the crank acting on the pedestal 2 is inevitably switched from the pushing force to the pulling force. There is also a problem that it is easy to cause a failure. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned inconveniences of conventional massagers and to provide a massager capable of smoothly reciprocating a footrest at a desired speed distribution.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a grooved drum is provided in the lower part of the footrest in parallel with the reciprocating direction of the footrest, and a driven pin is provided on the footrest in a proper position on the lower surface. Then, this is fitted in the groove of the grooved drum, and the groove is reciprocally moved by rotating the grooved drum by the drive motor, thereby achieving the above object.

[0005]

The massager according to the present invention is configured such that the rotation of the grooved drum is converted into the reciprocating motion of the driven pin and transmitted to the footrest. Make a round trip.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A massager according to the present invention will be specifically described below based on the illustrated embodiments. In this embodiment, the massager, like the conventional massager described above, has a body case 5 with a height of about 100 to 200 mm, and is provided on the body case 5 with an amplitude of about 20 to 40 mm. It consists of a pedestal 6 that reciprocates left and right. The body case 5 is
It is a support stand for supporting the foot stand 6 and at the same time it is intended for safety of use. The drive motor 7 and other drive mechanisms are housed inside so that these may not come into contact with the human body. It has become. Further, although not shown, a remote control type timer, a power cord, etc. are connected to the main body case 5, and a handle is attached at an appropriate position for convenience of use. The footrest 6 has a curved upper surface that conforms to the shape of a person's ankle, and prevents the ankle from slipping sideways when the ankle is placed in a supine position and reciprocated. It has become. The main body case 5 has a through hole 51 formed in the ceiling in the left-right direction, and a rail 52 is provided below the through hole 51. Further, below the rail 52, a grooved drum 71 is provided in parallel with the rail 52. Is provided. Further, a traveling member 61 is attached to the lower surface of the leg stand 6, reaches the rail 52 through the through hole 51, is engaged with the rail 52, and reciprocates left and right along the rail 52. It is supposed to do.
The grooved drum 71 is connected to the drive motor 7 so as to rotate at a speed of about 100 to 150 times per minute, and a groove 72 is formed in the body surface thereof. On the other hand, a driven pin 62 is attached to a proper position of the traveling member 61 so as to face downward. This grooved drum 71 and the driven pin of the traveling member 61
62 is a driving member, the driven pin 62 is fitted in the groove 72 of the grooved drum 71, and when the grooved drum 71 is rotated, it is pushed by the inner wall surface of the groove 72 and left and right along the rail 52. It is designed to reciprocate. Then, this movement is transmitted to the pedestal 6, and each time the grooved drum 71 is rotated once, the pedestal 6 reciprocates once. In the figure, the groove 72
Is displayed only on the front side of the grooved drum 71,
Actually, it is also cut on the back side, and both are continuous at points a and b, forming one circle.

The figure shows a state in which the pedestal 6 is moved to the rightmost. When the grooved drum 71 is rotated in this state, the driven pin 62 is pushed to the left by the inner wall surface on the right side of the groove 72. When the grooved drum 71 makes a half turn, it reaches the leftmost point (point b). In addition, the grooved drum 71
When driven, the driven pin 62 is pushed to the right by the inner wall surface on the left side of the groove 72, and when the drum 71 makes a half rotation,
Return to the original position (point a). That is, the distance between the points a and b becomes the amplitude of the reciprocating motion of the driven pin 62 (the foot 6), and the rotation speed of the grooved drum 71 becomes the vibration speed. Also, point a and b
When the inclination angle of the groove 72 with respect to the axial direction of the grooved drum 71 at each position between the point and the point is Θ, the driven pin 62 moves each position at a speed proportional to cos Θ.

[0008]

As described in detail above, the massager according to the present invention is configured so that the rotation of the grooved drum is converted into the reciprocating motion of the driven pin and transmitted to the footrest. Each time the drum makes one revolution, it makes one reciprocation. In particular, since the transition speed of the driven pin is defined by the inclination angle of the groove with respect to the axial direction of the grooved drum, the grooved drum can be formed at an arbitrary angle by forming the groove at an appropriate angle at each position. It is possible to reciprocate with speed distribution.
Therefore, not only the transition speed in the middle of the forward and return paths, but also the acceleration of the starting part and the deceleration of the end point, etc. are highly effective for massaging the legs, and the switching between the forward and return paths is performed smoothly. It can be prepared.
