Abstract

A hand-held massager having a plurality of attachments; all the attachments being driven by a single drive unit via a rotating cam so that massaging is effected by increasing the massaging range and gently patting the skin surface.

Claims

1. A massager comprising:

pushing attachments;

drive means for reciprocating said pushing attachments, said drive means having a rotating cam means engaging with each of said pushing attachments, said rotating cam means formed in such a manner that a position of said pushing attachments in a reciprocating direction sequentially changes corresponding with a rotating angle position of said rotating cam means, a length of said reciprocation of said pushing attachments corresponding with a rotating angular position of said rotating cam means, said pushing attachments being sequentially driven by said rotating cam means;

independent energy storage means for each pushing attachment storing energy when corresponding said pushing attachment is retracted and releasing said stored energy when said corresponding pushing attachment is moved forward;

a pushing force adjusting plate adapted to be slidable with respect to said attachments; and

adjusting means for adjusting the position of said adjusting plate for selectively varying the energy in each of said independent energy storage means.

2. A massager as set forth in claim 1 wherein:

said pushing attachments are five in number.

3. A massager as set forth in claim 1 wherein said rotating means has at least two crest;

the surface of said rotating cam means gradually increasing linearly in inclination angle before each crest, and falling vertically beyond each crest.

4. A massager as set forth in claim 1, wherein said adjusting means having a pushing force adjusting cam of for adjusting the position of said pushing force adjusting plate is formed in a stepped shape.

5. A massager as set forth in claim 1 wherein each of said pushing attachments having a pushing portion is formed into a semi-spherical shape.

6. A massager as set forth in claim 1 wherein each of said pushing attachments having a pushing portion is attached to an attachment connection and an attachment cushioning portion.

7. A massager as set forth in claim 6, wherein:

said attachment cushioning portion is made of rubber.
