CROSS-REFERENCE TO RELATED APPLICATION [0001] The present application claims priority under 35 U.S.C. .sctn.119(e) to U.S. Provisional Patent Application No. 60/695,643, filed Jun. 30, 2005. BACKGROUND OF THE INVENTION [0002] 1. Field of Invention [0003] This invention relates to apparatus useful in painting applications, and more specifically to a hand-held painting tool with an internal paint reservoir that selectively dispenses paint to quickly and accurately apply paint around trimwork and molding. [0004] 2. Description of Related Art [0005] There are numerous existing trim and edging tools used to prepare trim surfaces prior to painting. They include rollers, brushes, pads, and the like, and are used by painters to make the job of applying paint more efficient. For the most part, these painting tools need to be dipped or rolled in a paint bucket or tray to recharge the tool with paint. Applying paint to them in a consistent manner is a problem that leads to getting paint on the very trim work that the paint applicator was designed to protect. Some painting tools have been made with an internal paint reservoir or continuous supply of paint to the paint applicator. It is, however, not always possible to accurately control the amount of paint being released to the paint applicator on the tool. This leads to uneven placement of paint causing streaks, drips and differing textures when the paint is applied. [0006] Another disadvantage associated with typical painting tools with roller or pad paint applicators is that in order to remove the applicator from the tool, it is usually necessary to grasp the outer surface of the applicator and remove it from some form of support. As the paint applicator being removed is normally covered with wet paint, the process of removing the applicator from the tool can be messy and often leads to paint getting on the hands and clothes of the person removing the applicator. [0007] Thus, there is a need for an improved painting tool that that reduces the mess during use and eliminates the need for the user have to continuously reload paint onto a paint roller or a paint pad to provide greater utility and convenience to the user. It also would be beneficial to have a painting tool with a paint applicator that can be removed quickly and easily without having to grasp or touch the paint-covered applicator. SUMMARY OF THE INVENTION [0008] One aspect of the invention is directed to a painting tool for painting trimwork. The painting tool includes a paint applicator for applying paint to a surface to be painted. The tool also has an upper housing forming a paint reservoir and a lower housing slideably received by the upper housing so that the lower housing moves between a first position and a second position relative the upper housing. The paint applicator is connected to the lower housing such that by pushing the paint applicator against the surface to be painted, the lower housing is moved from the first position to the second position relative the upper housing. The tool also has a pumping mechanism fluidically connecting the paint reservoir in the upper housing to the paint applicator. The pumping mechanism includes a valve that is operated by movement of the lower housing between the first position and the second position such that the valve substantially prevents the flow of paint from the paint reservoir to the paint applicator when the lower housing is in the first position and the valve permits the flow of paint from the paint reservoir to the paint applicator when the lower housing is in the second position. Therefore, paint is selectively caused to be released from the paint reservoir to the paint applicator by pushing the paint applicator against the surface to be painted. [0009] Another aspect of the invention is directed to a painting tool that includes a housing forming a paint reservoir, a paint applicator for applying paint to a surface to be painted and a pumping mechanism fluidically connected to the paint reservoir. The pumping mechanism has a first or disabled condition and a second or activated condition, wherein the pumping mechanism seals the paint in the reservoir when in the disabled condition, and the pumping mechanism dispenses paint to the paint applicator when in the activated condition. The release of paint to the paint applicator by the pumping mechanism is selectively controlled by pushing the paint applicator against the surface to be painted to shift the pumping mechanism from the disabled condition to the activated condition. [0010] In one embodiment, the pumping mechanism includes a paint passageway, a stop plug at an entrance end of the paint passageway, a check valve in the paint passageway, and a valve means for selectively stopping or permitting flow through the paint passageway. A paint outlet conduit downstream of the valve means directs the paint to the paint applicator when the applicator is pressed against the surface to open the pathway through the valve means. [0011] In one embodiment, the housing includes an upper housing that forms the reservoir and a lower housing having the paint applicator connected thereto. The upper housing is slideably received by the lower housing such that when the when the paint applicator is pushed against the surface to be painted, paint is dispensed from the reservoir. [0012] These and other features and advantages of this invention are described in, or are apparent from, the following detailed description of various exemplary embodiments of the systems and methods according to this invention.
