Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
In a massaging vibrator device wherein massaging is done by a vibrating pad (26) attached to a pad plate (25) when said pad (26) is applied to a human body, said massaging vibrator having a longitudinal case and frame (5, 7) with grip means (8, 9) extending longitudinally out of said case and frame, with a motor (1) having output ends disposed in said case body and frame and longitudinal crank shaft means (3) coupling the motor output ends to the frame, the improvement therein including: (a) first and second eccentric balance weight means (2) disposed on said crank shaft means (3) at said motor output ends said eccentric balance weight means (3) being disposed in opposed phase, and, (b) pad coupling means (24) between said motor (1) and said pad plate (25) directly coupling the motor to the pad, whereby said eccentric balance weight means cause the motor and coupled pad to vibrate.
Claim 2
Dependent Claim
154 words
In a massaging vibrator device wherein massaging is done by a vibrating pad (26) attached to a pad plate (25) when said pad (26) is applied to a human body, said massaging vibrator having a longitudinal case and frame (5, 7) with grip means (8, 9) extending longitudinally out of said case and frame, with a motor (1) having output ends disposed in said case body and frame and longitudinal crank shaft means (3) coupling the motor output ends to the frame, the improvement therein including: (a) first and second eccentric balance weight means (2) disposed on said crank shaft means (3) at said motor output ends said eccentric balance weight means (3) being disposed in opposed phase, and, (b) pad coupling means (24) between said motor (1) and said pad plate (25) directly coupling the motor to the pad, whereby said eccentric balance weight means cause the motor and coupled pad to vibrate.
Claim 3
Dependent Claim
78 words
A device as claimed in claim 1 including a motor support shaft (12), adjacent said pad plate (25), supported by said frame (7); a motor center section, on said motor (1), with a motor supporter (11), extending from said motor center section to said support shaft (12); pipe coupling means (13), coupling said motor supporter (11) and said shaft (12); and, elastic material (14) on said shaft (12) between said frame (7) and said pipe coupling means (13).
Claim 4
Dependent Claim
125 words
A device as claimed in claim 1, including a motor rotor (23), a lead wire cap (15) in said frame (7) adjacent said motor (1) said cap (15) having an inner section facing said motor, a conductive terminal (16) in said inner section with a lead wire (17), a conductive spring (18) in said inner section coupled to said terminal (16), a brush presser on said motor opposite said inner section, a brush holder (21) on said motor for holding a carbon brush (20) therein, spring means (22) in said brush holder (21) for biasing brushes in said brush holder (21) onto said rotor (23); and, said pad coupling means (24) comprising a motor foot (24) extending from said motor to said pad plate (25).
Claim 5
Dependent Claim
28 words
A device as claimed in claim 1 wherein said crank shaft means (3) includes elastic material (27) between one motor output end and said case and frame (5,7).
Claim 6
Dependent Claim
19 words
A device as claimed in claim 1 wherein said eccentric balance weight means (3) consists of eccentric weight pieces.
Claim 7
Dependent Claim
25 words
A device as claimed in claim 1 wherein said eccentric balance weight means consists of identical weight pieces mounted on eccentric shafts of opposed phase.
