Abstract
Abstract The invention is an angularly adjustable paint roller assembly which attaches to the end of an extension pole and is characterized by an adjustable elbow brace which provides supplemental support to the adjusting pivot and establishes a position of maximum adjustment of on the order of 80° for the roller which defines an optimal angle for certain applications of the roller assembly and another position is struck by forwardly thrusting the pivot point of the elbow brace, establishing a roller angle of about 45° to the handle, so that in addition to being continually adjustable from 0° to 80° three distinct angles, including straight, may be quickly and accurately established.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
223 words
A multi-position paint roller frame comprising: (a) a shank; (b) a roller support bar pivotally mounted to said shank; (c) said roller support bar establishing an axis for a paint roller and being pivotal such that said axis defines a variable angle with said shank; (d) an elbow brace defined by two legs pivoted together at one end to define a central pivot point of said elbow brace; (e) said shank, legs and roller support bar portion establishing the roller axis lying substantially in one plane and movable relative to each other in said plane; (f) said elbow brace being pivotally mounted to and between said shank and said roller support bar and the legs being of a size such that the following three angular orientations of said axis relative to said shank are alternatively possible; (i) a 0° deflection position wherein said axis and shank are perpendicular and said elbow brace is straight; (ii) a position of maximum deflection of said roller axis wherein the central pivot point of said elbow brace is thrust rearwardly essentially against and supported by said shank; (iii) a position intermediate the positions described in (i) and (ii) wherein said central pivot is forwardly thrust to rest substantially against and support said roller support bar; and (g) means to maintain the legs in a selected adjusted position.
Claim 2
Dependent Claim
223 words
A multi-position paint roller frame comprising: (a) a shank; (b) a roller support bar pivotally mounted to said shank; (c) said roller support bar establishing an axis for a paint roller and being pivotal such that said axis defines a variable angle with said shank; (d) an elbow brace defined by two legs pivoted together at one end to define a central pivot point of said elbow brace; (e) said shank, legs and roller support bar portion establishing the roller axis lying substantially in one plane and movable relative to each other in said plane; (f) said elbow brace being pivotally mounted to and between said shank and said roller support bar and the legs being of a size such that the following three angular orientations of said axis relative to said shank are alternatively possible; (i) a 0° deflection position wherein said axis and shank are perpendicular and said elbow brace is straight; (ii) a position of maximum deflection of said roller axis wherein the central pivot point of said elbow brace is thrust rearwardly essentially against and supported by said shank; (iii) a position intermediate the positions described in (i) and (ii) wherein said central pivot is forwardly thrust to rest substantially against and support said roller support bar; and (g) means to maintain the legs in a selected adjusted position.
Claim 3
Dependent Claim
39 words
Structure according to claim 1 wherein the angle defined between said shank and said axis is on the order of 10° in the position described in (ii) and on the order of 45° in the position described in (iii).
Claim 4
Dependent Claim
63 words
Structure according to claim 1 wherein said roller support bar is mounted on said shank by means of a knuckle joint which defines two positions of maximum pivoting of said roller support bar relative to said shank corresponding to the positions described in (i) and (ii) above so that dual reinforcement is provided to the roller support bar in said last mentioned positions.
Claim 5
Dependent Claim
34 words
Structure according to claim 1 wherein the central pivot point of said elbow brace is defined by a bolt and wing nut to permit infinite variation of the angular adjustment of said elbow brace.
