Abstract

A motor-driven massaging apparatus obtains a massaging effect by applying pressure and vibration to a human body. The motor-driven massaging apparatus includes a finger-pressure roller which incorporates a DC-driven vibrator therein and operating handles project from both sides of the finger-pressure roller. A power supply part having batteries as a driving source is installed in the handle, and the vibrator is connected electrically to the power supply part. Batteries are used as a source of driving the vibrator, and therefore the location of use in not limited, and no connection of a cord is necessary.

Claims

1. A motor-driven massage apparatus comprising a pressure roller means, a motor-driven vibrator disposed in said roller means for effecting vibration of said roller means, said roller means having a longitudinal axis extending between two longitudinal ends, elongated handles extending from each longitudinal end of said roller means, each of said handles having a handle axis aligned with said longitudinal axis of said roller means, and a battery box means detachably mounted on one of said handles juxtaposed to said roller means, said battery box means housing a battery means for driving said motor driven vibrator, wherein said battery box means comprises a generally cylindrical body having an internal axial passage, said one handle extending through said axial passage.

2. A motor-driven massage apparatus according to claim 1, wherein said battery box means is detachably mounted on the outside of said one handle.

3. A motor-driven massage apparatus according to claim 1, wherein said cylindrical body comprises two half body parts, pivot means pivotably mounting said two half body parts on one another about a pivotal axis spaced from and parallel to said longitudinal axis of said roller means.

4. A motor-driven massage apparatus according to claim 3, wherein said two half body parts have locking means for locking said two half body parts in a closed position in which said two half body parts mate to form a cylinder, said locking means being releasable to permit said two half body parts to be relatively pivoted about said pivot means from said closed position to an open position.

5. A motor-driven massage apparatus according to claim 4, wherein said locking means comprises means defining an engaging opening in one of said half body parts, said locking means further comprising an engaging piece formed between two spaced grooves in said other half body part, said engaging opening receiving said engaging piece to lock said two half body parts in said closed position.

6. A motor-driven massage apparatus according to claim 5, wherein said means defining said engaging opening comprises a structure having a mouth receiving said engaging piece, said mouth having a side wall, an engaging hole in said side wall, said engaging piece having an end formed with a hooked part which is received in said engaging hole when said two half body parts are locked in said closed position.

7. A motor-driven massage apparatus according to claim 4, further comprising electrical contact means on each half body part, said electrical contact means on each body part making electrical contact when said two half body parts are in said closed position, said electrical contact means being separated from one another when said two half body parts are pivoted about said pivot means from said closed position to said open position.

8. A motor-driven massage apparatus according to claim 1, wherein said battery means comprises a plurality of batteries disposed in said battery box means, each of said plurality of batteries being disposed externally of said one handle.

9. A motor-driven massage apparatus according to claim 1 further comprising electrical connecting means extending between said battery box means and said motor driven vibrator, said electrical connecting means comprising one electrical lead part within said one handle and another electrical lead part externally of said one handle.

10. A motor-driven massage apparatus according to claim 9, wherein said one handle has a longitudinal end, said electrical connecting means further comprising an electrical connecting terminal in said longitudinal end, an electrical plug insertable into said connecting terminal, said connecting terminal being connected to said one electrical lead part within said one handle, said plug being connected to said other electrical lead part externally of said one handle.
