  • Patent number: 6957470
    Abstract: Disclosed herein is a corner painting tool, typically comprising at least four replaceable rollers pivotally attached to a handle, that provides for the painting of the two adjoining surfaces forming a typical 90° interior corner in an even and efficient manner. Each pair of rollers is detachably attached to one of two axle-bearing elements that are, in turn, rigidly affixed at opposite ends of a connector bar. The fixed relationship between the connector bar and the axle-bearing elements serve to position each pair of rollers at a 90° angle to the other. A handle is pivotally attached at the midpoint of the connector bar. Attachment at the bar's midpoint serves to locate the pivot point as close as possible to the inside corner formed by the rollers, thereby maximizing the stability of the overall assembly during use.
