BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a massaging apparatus for applying a massaging action to a user through a reciprocating drive of massage rollers.
2. Description of the Related Art
In general, this type of massaging apparatus includes a base covered at its open upper side with a cover and holders equipped with massage rollers and capable of freely running, and is adapted to impart a massaging action to the user in bed in a supine position by reciprocably running the holders by a drive means.
The massaging apparatus has a mattress type and a chair type and, usually, the former type includes two holders provided at a given interval in a running direction in a spaced-apart relation and the latter type includes one holder capable of freely running.
In either case, in order to enhance a massaging effect, a plurality of massage rollers are rotatably supported at given intervals in a spaced-apart relation in a width direction at least intersecting with the run direction of the holder. These massage rollers are run while pushing against both the sides of the backbone and legs of the user.
The massage rollers run along the uneven surfaces of the backbone and legs of the user, but such uneven surfaces are curved in the user's particular width direction and in a height direction. The area from the waist to buttocks is greater in the degree of curving than the rest of the body and, when such a curved area is massaged by massage rollers which are simply rotatable on the holders, only some of the massage rollers abut against the "back" surface of the user and the remaining massage rollers are sometimes hardly pressed against that surface.
Since, therefore, the massage rollers are not firmly abutted under a given pressure force against, for example, a narrow portion of the waist, recesses are formed at both the sides of the backbone and curved portion of the legs, no adequate massage effect is obtained and, in addition, projected areas are sometimes too strongly struck by some massage rollers and the user sometimes feels pain.
Still further, with such a massaging apparatus wherein the massaging action is applied to the user through the reciprocatory motion of the massage rollers over a base, the massaging effect is enhanced by more massage rollers. In the conventional massaging apparatus, however, one massage roller is provided on one reciprocably driven massage holder and sufficient numbers of massage rollers have not been provided in order to enhance a massaging effect adequately.
Thus the conventional massaging apparatus has the massage roller mounted on the holder in a manner to be simply rotatable. Therefore, the massage roller is sometimes too strongly abutted and sometimes not adequately struck against the curved areas on the backbone of the user. Further, it has not been the practice to provide many massage rollers on one holder. For this reason, it has not been possible to adequately enhance the massaging effect.
SUMMARY OF THE INVENTION
It is accordingly the object of the present invention to provide a massaging apparatus which can massage the curved backbone surface portion of the user under a good condition.
According to one preferred embodiment of the present invention, a massaging apparatus is provided for massaging a user, comprising: be freely rum; the guide section; rotation center oriented in a direction intersecting with the run direction of the travelling unit; wherein on the travelling unit.
According to the above arrangement, at least one of the roller support and massage roller is rotatably mounted on the travelling unit so that the massage rollers are rotated in accordance with the uneven surface of the user's body to enhance a massaging effect.
