Provided is a paint roller that may include a wire frame and a magnetic shield selectively attachable to the paint roller. The wire frame may comprise a configuration including multiple bends. In an embodiment, the wire frame may include a straight portion, a first bend, a second bend that directs the frame at a 180° angle relative to the straight portion, and a third bend that directs the wire frame at an angle less than the first and second bends. The bends and legs of the wire frame may be positioned in the same plane. The paint roller may further comprise a handle, a roller cage, and a roller cover. The magnetic shield may be selectively attachable to an end of the paint roller. The shield may include a generally circular shaped face that defines a circumference having a slightly smaller circumference than the circumference of the paint roller cover.

A reversible corner shield apparatus and methods of use, v-shaped or angled shaped shield having a first linear shield member or wing and a second linear shield member or wing which are connected or joined at an apex therebetween, a mount or connector positioned proximate the apex between the first linear shield member or wing and a second linear shield member or wing, a hinged connector attached to the mount on a first end of the hinged connector and an elongated handle connected to a second end of the hinged connector to enable rotation between the handle and the shield and, thus, functions to assist a solo painter in rotating and positioning the shield around inner and outer corners of flooring, baseboard, door and window trim or ceiling to shield these non-painted surfaces from over-paint, over spray, uneven transition lines, unsightly paint dabs and the like.

A wall painting assembly includes a handle unit for gripping. A shield is disposed on the handle unit for abutting against trim on a wall of a room. The handle unit is biased into a first position on the shield and the handle unit is urgeable into a second position on the shield. A roller unit is hingedly coupled to the handle unit to have paint applied thereon. The roller unit is urged downwardly when the handle unit is urged into the second position on the shield to apply the paint to the wall of the room. Additionally, the shield inhibits the paint from being applied to the trim on the wall. The roller unit is lifted upwardly when the handle unit is biased into the first position to inhibit the paint from being applied to the wall.

An end effector for a robot having a threaded shaft; a motor coupled to the shaft and configured to rotate the shaft about its axis; a nut threaded onto the shaft; a feature for preventing the nut from rotating about the axis of the shaft; and an elongate member fixed at one end to the nut and extending from the nut in a direction parallel to the axis of the shaft. The end effector may further include a container for containing a fluid having an elongate body portion having an opening at one end; and a reciprocable plunger extending into an opposite end of the body portion. A second end of the elongate member may be coupled to the plunger.

A roller cover and associated pair of cams attachable to opposite ends of the roller cover. Each of the cams has an outer diameter extending radially outwardly beyond an outer diameter of the roller cover a predetermined distance for maintaining the outer diameter of the roller cover a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface.

A paint roller and paint roller shield assembly comprises a roller for applying paint, having a paint applying surface that terminates at a rim located at an end of the roller. A paint roller shield, connected to the end of the roller, comprises a plate with a planar surface having a substantially round and beveled peripheral edge and a curved cutout configured as a missing portion of the plate. The beveled peripheral edge is angled and sloped outwardly away from the planar surface. In a plan view of the plate, the cutout exposes a part of the rim comprising part of the paint applying surface of the roller and wherein the plate and the beveled peripheral edge covers a remaining part of the rim of the roller not exposed by the cutout.

A roller cover and associated pair of cams attachable to opposite ends of the roller cover. Each of the cams has an outer diameter extending radially outwardly beyond an outer diameter of the roller cover a predetermined distance for maintaining the outer diameter of the roller cover a corresponding distance from the surface being coated during rotational movement of the roller cover over the surface to act as a thickness gauge for the coating being applied to the surface.
