摘要:
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.

An apparatus for temporarily storage of paint roller sleeves, the roller cage, and a portion of the handle assembly. The apparatus consists of an enclosure receiving the roller sleeve, the roller cage, and a portion of the handle assembly and also fully enclosing the roller sleeve and the roller cage.

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.

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. The pad is deformable which provides the operator with added comfort by improving the fit between the operator's palm and the spray gun handle grip, thus reducing fatigue and stress. The material of the pad allows for a better grip by the operator on the spray gun handle. In addition, the material of the pad combined with its positioning against the operator's palm acts to distribute heat away from the hand of the operator. The pad is designed to accommodate different hand sizes and shapes without the need to remove and replace hand grip covers or sleeves. The deformability of the pad also allows the operator to modify his or her hand positions during operation which reduces operator fatigue and stress.
摘要:
A liquid dispenser arrangement includes a self-contained pump and a discharge head. The pump has a liquid reservoir, while the discharge head has an applicator construction and an aperture. The aperture will be in liquid flow communication with the liquid reservoir. The discharge head is constructed and arranged to selectively take in liquid from an external liquid source through the aperture and convey the liquid to the liquid reservoir, when a pressure differential is established between the liquid reservoir and the external liquid source by the pump. The discharge head is also constructed and arranged to selectively eject liquid from the liquid reservoir through the aperture for distribution by the applicator construction. The applicator construction preferably includes a molded, flexible member with the aperture being in a portion of the flexible member. Methods of assembly and use are also disclosed.
