A paint roller assembly, including a handle having an axially extending portion for mounting a roller; one end of the axially extending portion having an engagement member; and an end piece engaging the engagement member to hold the roller in place on the axially extending portion. The end piece has a pivoting latch for alternately gripping and releasing the engagement member.

Abstract:
An airless sprayer for paint or the like consists of an electric drive unit connected to a piston. Driven by the electric drive unit, the piston reciprocates within the cylinder, thus spraying the paint or the like. Because of the close tolerance between the piston and cylinder (typically about 0. 0002 to about 0. 0003 inches), the sprayed liquid provides a seal between the piston and cylinder. To prevent this tolerance from increasing to the point of failure, the cylinder is manufactured from nitride hardened steel. A process for manufacturing the airless sprayer is also disclosed.

International Classification:
B05C 1/00
US Classification:
401197, 401173, 401176, 401182
Abstract:
An apparatus for painting a surface, having an absorbent paint applicator containing paint and contacting the surface; a tube filled with paint and connected to the applicator; and a metering device for incrementally metering paint onto the applicator from the tube. The metering device has a plunger reciprocating within the tube, with the plunger having a handle. The plunger can either be incrementally advanced within the tube by rotating the handle, thereby incrementally dispensing paint onto the applicator, or the plunger can be manually retracted within the tube to fill the tube with paint and manually advanced within the tube to dispense the paint. The plunger is helically grooved along its length and a converter translates rotation of the handle into linear motion of the plunger, thereby advancing the plunger within the tube.
Vibration Reduction Pad For Hand-Held Paint Spray Guns

International Classification:
B05B 7/02
US Classification:
239525, 239526, 239530
Abstract:
A pad for handle grips of hand held paint spray guns. Frequent prolonged use of paint spray guns can result in the fatiguing and stressing of operator hands. Fatigue and stress can be aggravated by requiring the operator to hold his or her hand in essentially one position on the handle grip. The pad reduces such fatigue and stress. The pad fits within a recessed region that is molded into the paint spray gun handle where the operator's palm meets the grip. Alternatively, the pad could be attached to existing paint spray gun handle grips that are lacking the recessed region. The pad is made of a material that is less dense than the synthetic resinous material of the spray gun handle grip. Preferably, the material is plastic foam or gel and is attached to the spray gun handle using an acrylic glue. The pad is designed to absorb some of the vibrational energy that is transmitted to the operator's hand in current spray gun handles. This reduction in vibrational energy transmission decreases operator fatigue and stress.

Abstract:
A hand-held trim painting tool consists of a cylindrical body holding paint to be dispensed in a reservoir within the cylindrical body, a head attached to the body, a removable paint applicator attached to the head, a mechanism for loading paint into the reservoir, a valve permitting paint to be dispensed from the reservoir, an actuator incrementally opening and closing the valve, and a dispensing rate adjuster to regulate the rate at which paint is dispensed.
