BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage device suitable for use by incorporating it into a chair or bed.

[0002]

2. Description of the Related Art There are various types of massage devices, for example, a massage device incorporated into a chair or bed. In such a massage device, the massage device has various functions in order to enhance the massage effect given to the user as much as possible.

The massage device has a function of rubbing the user's body and a function of striking it. When rubbing the user's body, the pair of massage rollers are simultaneously driven in the width direction in which they approach and separate from each other on the plane and in the front-back direction intersecting the width direction, thereby closing the pair of massage rollers on the plane. It is required to drive so as to draw a loop-shaped trajectory. Further, when hitting the user's body, it is required to drive the pair of massage rollers in a vertical direction intersecting the width direction.

Some conventional massage devices have the above-mentioned kneading function and hitting function. However, these functions are completely different in the movement direction of the massage roller. That is, in the kneading function, the movement direction of the massage roller is the width direction and the front-back direction on the plane as described above, and in the case of the tapping function, the movement direction is the vertical direction intersecting the plane, and in all these movement directions. Nothing that could be driven at the same time was developed.

Therefore, in the conventional massage device, the user must selectively receive the massage of kneading or tapping, which is inconvenient because he cannot receive the massage at the same time. In addition, if the massage of kneading and tapping is always received at the same time, there is an inconvenience that the user cannot select the type of massage depending on the physical condition at that time. Therefore, it is desired to develop a massage device that can receive massages of rubbing and tapping at the same time and that can selectively receive these massages.

[0006]

As described above, the conventional massage device has the inconvenience of not only being able to receive massages of rubbing and tapping at the same time, but also not being able to arbitrarily select those massages.

The present invention has been made in view of the above circumstances. An object of the present invention is to provide a massage device which can receive massages of rubbing and tapping at the same time, and which can selectively receive these massages. To provide.

[0008]

In order to solve the above problems, the present invention is directed to a base, a support shaft rotatably supported by the base, an eccentric shaft, and an axis line of the support shaft. A pair of cam bodies that are inclined in the opposite direction to the direction, an attachment body in which the middle portion is rotatably supported by the cam bodies, and a massage that is rotatably provided at one end of the attachment body. A roller and a massage roller provided at one end of the mounting body by rotationally driving the support shaft, in a width direction along the axial direction of the support shaft according to the eccentric amount and the inclination angle of the cam body, and the width direction thereof. A first driving means for displacing along the front-rear direction intersecting with and a second end of the mounting body for driving the mounting body at an angle within a predetermined range with an intermediate portion supported by the cam body as a fulcrum. Swing the massage roller to the front-back direction. Second driving means for displacing along the intersecting vertical direction, selection means for arbitrarily selecting the driving of the massage roller by the first driving means and the driving of the massage roller by the second driving means are provided. It is characterized by

[0009]

According to the above construction, by freely selecting the driving of the massage roller by the first driving means and the second driving means, the rubbing motion and the tapping motion of the massage roller can be performed simultaneously or separately. You can

The one end and the other end of the are respectively wound with their ends fixed. An intermediate part of the wire 95 is engaged with an intermediate pulley 96 provided at the other end of the box-shaped body 91.

The intermediate pulley 96 of the wire 95 and the first,
An actuating body 97 is connected to one of the pair of straight line portions located between the second pulleys 93 and 94. The actuating body 97 is movable along a guide rod (not shown) provided along the longitudinal direction inside the box-shaped body 91. The massage device M is attached to the operating body 97. Further, the upper opening of the box-shaped body 91 is covered with a sheet 98 such as cloth.

When the drive mechanism 92 is actuated to rotate the first pulley 93 clockwise and the second pulley 94 counterclockwise, for example, one end of the wire 95 is moved to the first pulley 93. And the other end is paid out from the second pulley 94. As a result, the linear portion of the wire 95 to which the operating body 97 is connected travels in the direction of the arrow, and the operating body 97 interlocks with the travel. Therefore,
If the user lies on the seat 98, the user can receive a massage over the entire back surface.

When the massage device M is used for the bed 72, a support roller 99 is rotatably provided in the massage device M so that the massage device M can smoothly run and move the massaging roller 17. This support roller 9
9 allows the load of the user lying on the seat 98 to be received.

In the massage device M having the above structure, when the first drive source 44 is operated to drive the drive pulley 46 to rotate clockwise in the direction indicated by the arrow A in FIG. 6, the driven pulley 35 is also driven via the timing belt 47. It is driven to rotate clockwise. The rotation of the driven pulley 35 is transmitted to the support shaft 3 via the helical gear train and also to the first driven shaft 34a via the one-way clutch 36.

When the support shaft 3 is rotationally driven, the massage roller 1 is moved by the cam body 4 attached to the support shaft 3.
The mounting body 9 on which 7 is supported makes eccentric rotation according to the amount of eccentricity e and swinging movement along the axial direction of the support shaft 3 according to the inclination angle θ. That is, the pair of massage rollers 17 are driven in the width direction along the axial direction of the support shaft 3 and in the front-rear direction intersecting with the axial line to perform a kneading motion that draws a loop-shaped locus shown by X in FIG. 2 on the plane. , Rubbing and rubbing the user's body.

The first driven shaft 34a is rotationally driven together with the support shaft 3 via the one-way clutch 36, so that a third rotating body integrally provided on the first driven shaft 34a. 32 is rotationally driven. This third rotating body 3
When 2 rotates, one end is connected to the second drive shaft 26 eccentrically connected to the second drive shaft 26 and the first rotary body 27 connected to the second drive shaft 26. Drive shaft 26
And the first drive shaft 25, which is connected with its axis shifted and the other end of which is eccentrically connected to the second rotating body 29, is eccentrically rotated with their phases shifted by 180 degrees. As a result, the holder 23 provided in the middle of each drive shaft 25, 26 is eccentrically rotated (oblong movement), and the second arm portion 1 of the mounting body 9 is rotated.
Since it slides along the long hole 18 formed in 2, the mounting body 9 swings through the second arm portion 12 around the middle portion pivotally attached to the cam body 4. This swinging motion causes the massage roller 17 attached to the first arm portion 11 to make a hitting motion in which the massage roller 17 is displaced in the vertical direction, so that both massage of kneading and hitting are given to the user at the same time. Thereby, the massage effect can be sufficiently enhanced.

The support shaft 3 and the first and second drive shafts 2
If the ratio of the number of rotations to 5, 26 is set to, for example, 1:20, the massage roller 17 reciprocates up and down 20 times while performing one loop-shaped kneading motion shown by X in FIG. You will be hitting.

Further, since the hitting motions of the pair of massage rollers 17 are 180 degrees in phase, the user alternately hits the part to be massaged, which also results in a comfortable massage effect for the user. Can be given.

Drive pulley 4 driven by the first drive source 44
When the rotation direction of 6 is opposite to the direction of arrow A, the driven pulley 3
5 and the first driven shaft 34a, the one-way clutch 36 idles with respect to the first driven shaft 34a, so that only the support shaft 3 is rotationally driven via the helical gear train. .. Thereby, the pair of massage rollers 17
Is driven in the width direction indicated by the looped locus X and in the front-back direction, and is not driven in the up-down direction, so that the user is given only a massage by a kneading motion. That is, the user can select the massage by the hitting motion.

When the second drive source 34 is operated to rotate the screw shaft 22, a pair of couplings screwed to the right screw part 22a and the left screw part 22b formed on the screw shaft 22. The body 19 can be driven towards or away from it.

The pair of connecting bodies 19 are integrally attached to an attaching body 9 on which the massage roller 17 is supported, and the attaching body 9 is held slidably in the axial direction of the support shaft 3. Therefore, when the coupling body 19 is driven, the massage roller 17 interlocks with the coupling body 19 and slides along the axial direction of the support shaft 3, so that the distance between the pair of massage rollers 17 can be adjusted. That is, by adjusting the interval between the pair of massage rollers 17 according to the physique of the user who receives the massage, the part to receive the massage,
You can receive a massage comfortably and effectively.

The distance between the pair of massage rollers 17 is equal to that of the pair of limit switches 6 provided on the inner bottom of the base 1.
Maximum and minimum are set by 4, 65. Therefore, the second drive source 54 may be operated too far in the separating direction to hit the pair of mounting bodies 9 on both side walls of the base 1, or may be operated in the approaching direction until the pair of mounting bodies 9 collide. It can be prevented.

In the above embodiment, the striking motion, which is the vertical movement of the massage roller, transmits the driving force of the first driving source to the first driving shaft and the second driving shaft via the one-way clutch. In other words, the support shaft and the first and second drive shafts can be driven by the first drive source.
The support shaft and the first and second drive shafts may be driven by different drive sources. That is, the support shaft may be driven by the first drive source, and the first and second drive shafts may be driven by the third drive shaft. By doing so, since the support shaft and the first and second drive shafts can be selectively operated, it is possible to perform the rubbing motion and the tapping motion of the massage roller simultaneously or separately. ..
