(d) a flow control mechanism operatively connected to said urging mechanism to controllably regulate flow of paint through said fluid coupling between no flow and selectively enabled flow positions;
(e) a trigger mechanism mounted to said handle housing and operatively connected to said flow control mechanism and operable between non-actuated and actuated positions by the same hand of a user that operatively holds said paint edging apparatus, said trigger mechanism being operable when moved to said actuated position to move said flow control mechanism to selectively enable fluid flow through said fluid coupling; and
(f) wherein said paint edging apparatus is operable to uniformly and continuously apply paint from said paint reservoir through said paint applicator to a work surface as said paint applicator is advanced along an edging path; and
wherein said painting module is rapidly detachable from said handle housing after use for disposal and/or replacement by another painting module.

Abstract
This document discusses, among other things, an apparatus for painting a work surface including a handle housing. A disposable painting module is configured to be removably engaged with the handle housing. The painting module includes a paint applicator configured to be removably engaged with the handle housing. The paint applicator is configured to apply paint to the work surface. A paint reservoir is fluidly coupled with the paint applicator and is configured to be removably engaged with the handle housing. An urging mechanism is coupled to the handle housing and configured to interact with the paint reservoir to substantially uniformly discharge the paint from the paint reservoir and supply the paint to the paint applicator.

14. A hand-held paint edging apparatus comprising:
-
(a) a handle housing arranged and configured to be operatively held and carried by a single hand of a user; (b) a removable and replaceable disposable painting module configured to be rapidly detachably engaged with and carried by said handle housing, said painting module comprising; (i) a paint applicator arranged and configured for detachable engagement with said handle housing and configured to slidably apply paint in an edging manner through a porous applicator to a work surface; (ii) a paint reservoir having an outlet fluidly coupled with said paint applicator and arranged and configured for detachable engagement with said handle housing, comprising; (1) a syringe body having a fluid outlet; (2) a plunger coaxially aligned for movement within the syringe body; and (3) an operative seal suitable for viscous fluids such as paint, said seal slidably, sealingly arranged between the syringe body and plunger, wherein movement of said plunger away from said fluid outlet creates a filling stroke for drawing fluid into said syringe body through said fluid outlet, and wherein movement of said plunger towards said fluid outlet creates a dispensing stroke for forcing fluid out of said syringe body through said fluid outlet; and (iii) a fluid coupling connected to operatively deliver paint from said reservoir fluid outlet to said paint applicator; (c) an urging mechanism including a constant force spring mounted to the handle housing, said urging mechanism arranged to operatively engage said plunger to help co-axially align the plunger within the syringe body, said urging mechanism arranged and configured to apply constant force to said plunger as it moves along its entire said dispensing stroke toward said fluid outlet; (d) an electric vibrator mounted to said handle housing and operatively connected to said paint applicator and to receive energizing power from a power source, for imparting when energized through a switch, oscillatory vibrating motion to said paint applicator; and (e) a trigger mechanism mounted to said handle housing and operatively connected to said switch and to said fluid coupling, said trigger mechanism being operable by the same hand of a user that operatively holds the paint edging apparatus, said trigger mechanism being operable between actuated and non-actuated positions to; (i) close said switch to provide energizing power to said electric vibrator, while simultaneously selectively enabling and controlling the rate of fluid flow through said fluid coupling when moved to said actuated position; and (ii) open said switch to de-energize said electric vibrator, and simultaneously stop fluid flow through said fluid coupling when moved to said non-actuated position; and (f) wherein said paint edging apparatus is operable to uniformly and continuously apply paint from said paint reservoir through said paint applicator to a work surface as said applicator is advanced along an edging path; and
wherein said painting module is rapidly detachable form said handle housing after use for disposal and/or replacement by another painting module. - View Dependent Claims (15, 16, 17, 18, 19, 20)
