Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
166 words
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, said rotating cam means having two crests, and a surface of said rotating cam means beyond each crest being inclined more steeply than said rotating cam means surface before each crest; and 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; and an attachment spacer for controlling a range of said reciprocating pushing attachments.
Claim 2
Dependent Claim
166 words
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, said rotating cam means having two crests, and a surface of said rotating cam means beyond each crest being inclined more steeply than said rotating cam means surface before each crest; and 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; and an attachment spacer for controlling a range of said reciprocating pushing attachments.
Claim 3
Dependent Claim
16 words
A massager as set forth in claim 1 wherein: said pushing attachments are three in number.
Claim 4
Dependent Claim
24 words
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.
Claim 5
Dependent Claim
29 words
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.
Claim 6
Dependent Claim
17 words
A massager as set forth in claim 4, wherein: said attachment cushioning portion is made of rubber.
Claim 7
Dependent Claim
59 words
A massager comprising: a pushing attachment; and drive means for retracting said pushing attachment into the massager and for limiting movement of said pushing attachment out of the massager, the speed of said retracting of said pushing attachment into the massager being slower than the speed of said limiting of movement of said pushing attachment out of the massager.
Claim 8
Dependent Claim
59 words
A massager comprising: a pushing attachment; and drive means for retracting said pushing attachment into the massager and for limiting movement of said pushing attachment out of the massager, the speed of said retracting of said pushing attachment into the massager being slower than the speed of said limiting of movement of said pushing attachment out of the massager.
