ABSTRACT:
A sectional paint roller tube for attachment to a paint roller axle. The roller tube of the present invention has a cylindrical, substantially hollow, endpiece having an opening formed in one end thereof; at least one split sleeve having an inner diameter sized to frictionally engage the paint roller axle and an outer diameter sized to be rotatably received within the endpiece; and a cylindrical, substantially hollow, cap having an opening extending therethrough. One or more extensions may be attached to the endpiece such that an assembled roller tube of a desired length is fabricated. The cap is attached directly to the endpiece if no extensions are utilized, and is attached to the final extension if one or more extensions are used. Thus, by utilizing a small number of standard parts, paint rollers of a wide variety of different lengths are fabricated. This eliminates the need to design and fabricate molds for various lengths of roller tubes, eliminates the requirement for inventorying various lengths of roller tubes, and simplifies the assembly process by eliminating the requirement for a given size roller tube in the construction of a paint roller of a desired length. The split sleeve both functions as a bushing upon which the roller rotates about the axle and also as a thrust bearing preventing lateral movement of the roller relative to the axle.
