Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 233 words
A device for treating the foot and body, comprising, an integral elongated symmetrical roller of overall circular cross-section throughout made up of a pair of spaced apart annular traction rings intervened by inwardly tapering studded base surfaces of lesser diameter, each base surface extending inwardly from one of the traction rings to an abrupt meeting with a central annular studded ridge, having a diameter less than that of a traction ring, the studded base surfaces being provided with uniform rounded studs of such dimensions and spaced apart effectively to form a primary treatment bed which supports a foot pressed against it from bearing against the base surface while each stud penetrates the flesh to exert kneading pressure on a specific area of the foot, the studs on the base surfaces being arranged laterally in circumferential spaced apart rows in which the individual studs are substantially uniformly spaced apart not more than the width of a stud nor less than half the width of a stud and adjacent studs of respective rows are spaced apart in the axial direction of the roller not more than the width of a stud nor less than half the width of a stud, the studs on the ridge being uniform and in a single row and substantially uniformly spaced apart whereby the ridge presents a relatively narrow secondary treatment bed for bedding down the foot for deeper penetration.
Claim 2
Independent Claim 233 words
A device for treating the foot and body, comprising, an integral elongated symmetrical roller of overall circular cross-section throughout made up of a pair of spaced apart annular traction rings intervened by inwardly tapering studded base surfaces of lesser diameter, each base surface extending inwardly from one of the traction rings to an abrupt meeting with a central annular studded ridge, having a diameter less than that of a traction ring, the studded base surfaces being provided with uniform rounded studs of such dimensions and spaced apart effectively to form a primary treatment bed which supports a foot pressed against it from bearing against the base surface while each stud penetrates the flesh to exert kneading pressure on a specific area of the foot, the studs on the base surfaces being arranged laterally in circumferential spaced apart rows in which the individual studs are substantially uniformly spaced apart not more than the width of a stud nor less than half the width of a stud and adjacent studs of respective rows are spaced apart in the axial direction of the roller not more than the width of a stud nor less than half the width of a stud, the studs on the ridge being uniform and in a single row and substantially uniformly spaced apart whereby the ridge presents a relatively narrow secondary treatment bed for bedding down the foot for deeper penetration.
Claim 3
Dependent Claim 37 words
A device, as defined in claim 1, in which the studs are rounded and have a lateral dimension of one centimeter plus or minus one third and a height of three millimeters plus or minus one third.
Claim 4
Dependent Claim 27 words
A device, as defined in claim 1, in which the roller is an integral body made of natural rubber having a hardness of 27 to 53 Dura.
Claim 5
Dependent Claim 12 words
A device, as defined in claim 1, which has rounded studded ends.
Claim 6
Dependent Claim 27 words
A device, as defined in claim 4, in which the rounded studded ends are of natural rubber softer than the rubber of the tapering surfaces and ridge.
Claim 7
Dependent Claim 29 words
A device, as defined in claim 5, in which the studs on the ends of the body are of natural rubber having a consistency of 25 to 30 Dura.
