Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
175 words
A massage means comprising a rigid right hand bar, a rigid left hand bar and an intermediate bar disposed between and connected end-to-end to said rigid right hand bar and said rigid left hand bar, said intermediate bar, said right hand bar and said left hand bar each having a length which is longer than their width and a width that is greater than their thickness, said intermediate bar having thick end portions having the same thickness as said right and left hand bars separated by a mid-portion which is thinner and narrower than said end portions, a pair of spherical pressing members with one each secured to said thick end portions of said intermediate bar perpendicular to its thickness, said mid-portion of said intermediate bar being resilient so that said mid-portion of said intermediate bar bends in a direction such that said spherical pressing members are moved in a direction toward each other when said right hand and left hand bars are moved in a longitudinal plane in a direction toward said pressing members.
Claim 2
Dependent Claim
175 words
A massage means comprising a rigid right hand bar, a rigid left hand bar and an intermediate bar disposed between and connected end-to-end to said rigid right hand bar and said rigid left hand bar, said intermediate bar, said right hand bar and said left hand bar each having a length which is longer than their width and a width that is greater than their thickness, said intermediate bar having thick end portions having the same thickness as said right and left hand bars separated by a mid-portion which is thinner and narrower than said end portions, a pair of spherical pressing members with one each secured to said thick end portions of said intermediate bar perpendicular to its thickness, said mid-portion of said intermediate bar being resilient so that said mid-portion of said intermediate bar bends in a direction such that said spherical pressing members are moved in a direction toward each other when said right hand and left hand bars are moved in a longitudinal plane in a direction toward said pressing members.
Claim 3
Dependent Claim
40 words
A massage means as set forth in claim 1 wherein said center portion of said intermediate bar comprises a band shaped portion which is easy to bend and has a length greater than a diameter of said spherical pressing members.
Claim 4
Dependent Claim
58 words
A massage means as set forth in claim 2 wherein each of said pressing members includes an external thread selectively engageable with a plurality of internal threads defined in each of said ends of said intermediate stick and spaced apart longitudinally of said intermediate stick, thereby rendering a distance between said pressing members and said intermediate stick variable.
Claim 5
Dependent Claim
71 words
The massage means as set forth in claim 1, wherein said intermediate bar has adjustable connecting means to connect said intermediate bar to said rigid right hand bar and said rigid left hand bar so that the distance between each of the pressing members and the ends of said right and left hand bars are adjustable by threading said right and left hand bars into or out of said intermediate bar.
Claim 6
Dependent Claim

Dependent Claim
19 words
The massage means as set forth in claim 6, further comprising a pulling rope attached to the ring pin.
Claim 9
Dependent Claim
35 words
The massage means as set forth in claim 1, wherein the intermediate bar has a center portion which is slightly curved in the bending direction in a state where no bending force is applied thereto.
Claim 10
Dependent Claim
33 words
The massage means as set forth in claim 1, wherein the intermediate bar is made of nylon in a unitary construction, and the right- and left-hand bars are made of an ABS resin.
