  • Patent number: 5611100
    Abstract: A lightweight paint roller frame for supporting a long cylinder. The present frame will accommodate a cylinder of a such a length that painting can be accomplished more quickly. This cylinder, because of its length, approximately two to three feet, has a unique support structure. The cylinder has uniformly spaced wheels along its length and is supported on both of its ends by a lightweight frame. To facilitate removal of a cover or nap from the cylinder, a rod which extends through the frame and the cylinder is removed. The frame is lightweight because it is made of plastic. The frame is preferably triangular and the area within the frame is substantially open. Support elements running within the open area of the frame are used to provide additional support to the frame without adding the weight of a solid area.

  • Patent number: 5509165
    Abstract: A paint roller with a frame providing maximum support for a cylinder while allowing easy removal of a cover on the cylinder. The cylinder is about two feet long for indoor use and three feet long for outdoor use. Because of this extended length, which is relatively greater than that of existing paint rollers, the coverage provided by the paint roller is greatly increased and less labor is spent in painting. To support this greater length of the cylinder, support wheels are provided one per each foot of length along the cylinder and the frame attaches to the cylinder on both sides. In order to provide access for the removal of the cover of the cylinder, one side of the frame pivots away from the cylinder. The frame has an arm that is hinged and another arm that is split such that it has two semi-circular portions. When the hinged arm pivots, the split arm separates and the frame is removed from one end of the cylinder, thus allowing for easy removal of the cover.
