  • Patent number: 5050261
    Abstract: An angularly adjustable adapter for paint rollers which connects into the handle of the paint roller. The device includes a pivotable knuckle, the first end of which connects to the paint roller handle. The second end of the knuckle is connected to an elongated downwardly extending extension arm and includes opposing outwardly facing friction surfaces. Two elongated spaced apart friction bars are pivotally connected at their upper ends to the knuckle first end about a common transverse axis and extend downwardly against and past the friction surfaces to a lower slotted transverse connection with respect to the extension arm. After the knuckle is manually angularly pivoted, the friction bars acting against the friction surfaces automatically maintain the preselected angle during painting use, also adding additional lateral ridigity to the knuckle.
