Abstract
Abstract A portable massaging device utilizing an AC motor having a high torque at a slow speed. The motor drive shaft operates a crank lever arm. The end of the arm is freely slidable within an elongated slot on a sliding member. Rotation of the crank arm will therefore cause reciprocation of the sliding member. A Bowdoin type cable is attached to the housing holding the sliding member with the operating central wire threadedly attached to the sliding member. The other end of the Bowdoin cable is mounted in a handle having a central axial opening. The central cable wire extends into this opening and is provided with a member having an internally threaded opening. Any suitable massaging attachment may be used. For example, the attachments may include brushes, vibrators, rollers, etc. Each attachment is provided with a carrier shaft having a threaded end which can be inserted into the handle and threaded into the member at the end of the central wire of the cable. With this hook-up, when the motor is turned on, the crank arm causes reciprocation of the sliding member. This causes the central cable wire to reciprocate so that its end will reciprocate within the axial handle opening. If the handle is grasped manually, the attachment will also reciprocate and can be applied to a suitable portion of the body.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
164 words
A portable massage device comprising a generally rectangular housing, a gear motor mounted in said housing, a drive shaft extending vertically from said gear motor, said housing having an upper enlarged portion, a flexible Bowdoin-type cable attached to the upper housing portion, said cable having an outer carrier sheathe and an inner operating wire core, means in said housing between said shaft and said cable for converting the rotary motion of said shaft to a reciprocating motion of said wire core, a manually graspable handle, the other end of said cable sheathe being mounted in said handle, a massaging attachment releasably mounted in said handle and attached to said wire core for reciprocating said attachment relative to said handle when said motor is operating, said upper housing portion having integral opposed tracks on the inner walls of the housing, and a rectangular plate having edge grooves for sliding movement along said tracks, said converting means including means for causing sliding reciprocation of said plate.
Claim 2
Dependent Claim
164 words
