Description

BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a paint roller cover for preventing splatter from a cylindrical paint roller pad during painting and for subsequently cleaning paint from paint roller pads, and in particular to a paint roller cover that can remain attached to a paint roller pad during use and cleaning.

(2) Description of the Prior Art

Paint is commonly applied to large surfaces, such as walls, with a cylindrical paint roller pad that is coated with paint and then rolled over the surface to be painted. Normally, the pad will be carried on a spindle rotatably mounted on a handle. Heretofore, removal of paint, especially latex paint, from paint roller pads has usually been performed by placing the roller pad under a faucet and massaging the pad with the fingers. This procedure, in addition to being messy and time consuming, normally leaves some of the paint in the pad. Devices have been purposed in which the pad is placed in housing and cleaned by pumping water through the housing. Designs so far purposed have met with little commercial acceptance.

Thus, there is a need for a simple, mess-free, efficient and economical device for cleaning paint from paint roller pads, and particularly a device that will also prevent splattering of paint during painting. In addition, there is a need for a quick clean-up paint roller splatter cover that can be compactly stored and displayed for retail sale.

SUMMARY OF THE INVENTION

This need is addressed by the present invention, which is comprised of a quick clean-up paint roller cover that is attachable to a source of water, such as a faucet or spigot. The cover is designed as a “universal” cover, i.e., a cover that can be attached to most commercially available paint roller spindles. The quick clean-up paint roller cover is generally comprised of a painting shield to prevent splatter of paint from the pad and catch paint drips during painting, a rinse shield operable in combination with the painting shield to partially cover the roller pad during cleaning, and a water source, i.e., a manifold, to tangentially spray water against a pad supported within the painting and rinse shields to rinse and spin clean the paint roller pad.

Preferably, the shields are molded of a transparent plastic so that the interior of the cover can be viewed during painting and cleaning. The painting shield is preferably integrally molded with the manifold.

More specifically, the painting shield of the invention is comprised of a semi-cylindrical side wall having a radius of curvature greater than the radius of the pad to be cleaned and a length greater than the length of the pad. The painting shield side wall has an inner surface, an outer surface, front and back edges, and end edges. Parallel end walls are located at the ends of the side wall, and are preferably integrally formed with the side wall. Normally, the painting shield side wall will extend around 180° or less of the pad when the pad is mounted.

The rinse shield is also comprised of a semi-cylindrical side wall having a radius of curvature greater than the radius of the pad to be cleaned, but less than the radius of curvature of the painting shield side wall, and a length greater than the length of the pad. The rinse shield has an interior surface, an exterior surface, leading and trailing edges, and end edges. The rinse shield also includes parallel end walls, with the rinse shield side wall being shorter than the painting shield side wall, so that the rinse shield end walls fit inside the painting shield end walls.

The rinse shield is rotatable attached to the painting shield and is rotatable between a closed position in which the rinse shield side wall is substantially beneath the paint shield side wall and a fully extended position in which the rinse shield side wall is substantially exposed. When in the rinse position, the paint shield and rinse shield in combination will extend partially around the circumference of the paint pad, leaving a gap between the edges of the shields to permit discharge of water during rinsing.

Preferably, the rinse shield also includes stops, e.g., cooperating notches and index tabs, to secure the rinse shield relative to the painting shield in the closed position during painting, and the fully extended position and intermediate positions during rinsing of the pad, creating a wider gap between the edges of the painting shield and rinse shield. For example, the rinse shield can be rotated to the full extended position or to two partially extended positions for fast, medium and slow pad cleaning. A thumb tab may be provided on the rinse shield to aid in manually moving the rinse shield to the different positions.

In addition to the painting and rinse shields, the cover also includes a liquid manifold integral with the cover positioned to deliver a curtain of liquid to the paint roller to wash paint from the cylindrical pad after painting. The liquid manifold comprises a tubular section having a hollow interior, a closed lower end and an open upper end adapted for attachment to a hose. The tubular section includes an elongated discharge opening or single slot in communication with the interior of the cover, whereby liquid is capable of flowing from the tubular section upper end through the hollow interior for discharge through the elongated discharge opening. In one embodiment, the elongated discharge opening is segmented to form a plurality of spaced, longitudinally aligned holes in communication with the cover's interior. These holes are preferably covered by the rinse shield when the rinse shield is in the closed position, preventing paint from clogging the holes. A plug may be needed to plug the end of the liquid manifold depending on the injection molding process used to manufacture the shield.

The cover also includes means for supporting a paint pad with the longitudinal axis of the pad being coincident with the axis of curvature of the painting and rinse shields, and means for a user to hold the cover and pad during painting. In a first embodiment, the pad is detachably supported on a rotatable spindle that includes a handle extending substantially transverse to the axis of the spindle, with the spindle being mounted on the end walls of at least one of the shields for rotation within the shields. For example, the spindle handle adjacent one end of the spindle can be clipped to one end wall adjacent the spindle, while the opposite end of the spindle can be inserted into a rotatable end cap supported on the opposite end wall. In a second embodiment, end caps are attached to the ends of the pad for use in rotatably attaching the pad to the end walls of at least one of the shields, and a handle is attached to the outer surface of the painting shield side wall.

More specifically, in a first embodiment, the cover is attached to a spindle or roller cage adapted to hold a rotatable cylindrical paint pad. The spindle includes a handle having an arm transverse to the spindle longitudinal axis, with a gripping section at the distal end of the arm. The spindle is rotatably supported on the end walls of the painting and rinse shields. For example, the distal end of the spindle, i.e., the end of the spindle opposite the handle grip, can be inserted into a bushing or other holder in one of the shield end walls, while the spindle at the intersection of the handle and spindle can be fitted into a slot in the painting shield end wall and/or the rinse shield end wall. An end cap can be fitted onto the distal end of the spindle to fit into the bushing or holder. The outer surface of the painting shield end wall adjacent the handle end of the spindle can also include a clip to secure the spindle handle to the end wall. The clip may be in the form of a pair of spaced fins projecting outwardly from the end wall with the spacing between the fins being equal to or slightly greater than the diameter of the paint roller handle.

In a second embodiment, a detachable handle clips onto the outer surface of the paint splatter shield. The detachable cover handle is preferably hollow and includes an open proximal end to receive an extension pole for painting ceilings, etc. Some retailers of the present invention may consider the detachable handle as an after market option since the paint splatter and rinse splatter shield combination can be used with spindle and handle type paint roller frames. On the other hand, some purchasers of the paint roller tool of the present invention may prefer the detachable handle instead of a traditional spindle and handle type paint roller. In this case, the detachable handle would be sold along with the painting and rinse shields. In either case, the same mold could possibly be used to manufacture the paint splatter and rinse splatter shields. Therefore, the present invention offers manufacturing and marketing efficiencies.

A hose is also provided to attach the paint roller cover to a faucet or spigot. Generally, the hose will be a rubber or plastic hose having a fitting at one end adapted for attachment to a faucet or spigot, and the fitting at the other end being adapted for attachment to the paint roller cover. In a preferred embodiment, the fittings at both ends are female fittings. It will be understood, however, that one of the fittings may instead be male fittings, such as on a garden hose, or both may be male fittings, depending on the design of the tool attachment ends. Moreover, a plastic tube is provided to package the hose for sale and storage. The plastic tube has a cavity large enough to accommodate the hose in a folded configuration. The plastic tube may also hold a sheet of instructions on how to use the paint roller tool. Preferably, the plastic tube is transparent and is insertable within the paint roller tool in place of a paint roller pad. However, the paint roller tool can also be packaged with a useable paint roller pad.

Further still, the paint splatter shield includes a paint extraction tool that is releasibly attachable to the shield outer surface. The paint extraction tool has a handle and blade, wherein the blade has a semi-circular outer edge sized to receive a substantial arc-length of the circumference of the cylindrical paint pad. A clip or gripper tab extending outwardly from the paint splatter shield outer surface holds the paint extraction tool onto the painting shield when the paint extraction tool is not in use.

The recommended first step in cleaning paint from a pad after painting is to remove the paint extractor tool from the clip on the outer surface of the paint splatter shield, and use it to scrape excess paint off the paint roller pad. Normally, the paint roller will be held with one hand to a position over a paint container while the other hand is used to scrape the blade of the paint extraction tool down the length of the paint roller pad, thereby scrapping excess paint off the pad and into the paint container. The roller pad can be rotated and scrapped until the desired amount of excess paint is removed. Then, the paint extractor tool is washed and returned to the gripper tab on the top of the paint roller cover.

The quick clean-up roller cover is then prepared for washing by attaching one end of a hose to a faucet or spigot, and the other end of the hose to the upper end of the liquid manifold adapted for attachment to a hose. Next, the rinse splatter shield is readied for use by gripping the rinse shield thumb tab with one hand while holding the paint splatter shield with the other and rotating the rinse shield to one of its wash positions. The faucet or spigot is then turned on to wash the roller cover and pad. Water then enters the liquid manifold adjacent to the body of the cover. As water pressure builds within the liquid manifold, jets of water exit the plurality of holes in the liquid manifold tubular section creating a curtain of water that impacts generally tangentially against the roller pad causing the roller pad to spin, exposing all parts of the roller pad and interior of the paint and rinse splatter shields to the curtain of water. The jets of water exit at an angle relative to the liquid manifold such that the various sized roller pads will spin when impacted. Centrifugal force resulting from the spinning, in conjunction with the force of the water curtain, forces the paint off of the roller pad and paint splatter shield. The rinse splatter shield contains the splatters resulting from the paint being forced off the paint roller by the curtain of water and centrifugal force. The liquid drainage gap between the back edge of the paint splatter shield and the leading edge of the rinse splatter allows the rinse solution to drain from the splatter shields and roller pad. Once the paint roller pad and roller are sufficiently clean of paint, the spigot or faucet is turned off, and the hose is removed from the liquid manifold. The rinse splatter shield is then rotated back to its stored position.

Other objectives of the invention will become apparent to one skilled in the art upon reading the following detailed description of the invention, taken with the drawings.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, terms such as horizontal, upright, vertical, above, below, beneath, and the like, are used solely for the purpose of clarity in illustrating the invention, and should not be taken as words of limitation. The drawings are for the purpose of illustrating the invention and are not intended to be to scale.

FIGS. 1 and 2 illustrate one embodiment of the paint roller cover. A quick clean-up paint roller, generally 10, is comprised of a spindle 12 adapted to hold a rotatable cylindrical paint pad 13, and handle comprised of an arm 16 and grip 18. A paint roller cover 20 is attachable to paint roller 10, and is used to catch paint drips and splatter as roller 10 is used to apply paint to a wall, etc. Roller cover 20 has a painting splatter shield 22 with a semi-cylindrical side wall 24 having an axis of curvature about a central axis 25. As best seen in FIG. 3 side wall 24 has an inner surface 26, an outer surface 28, a front edge 30 and a back edge 32. Parallel end walls 34 and 36 are integral with the ends of side wall 24. One of end walls 34 or 36 includes a handle retainer clip in the form of fins 37 for holding paint roller arm 16 at a fixed angle.

A liquid manifold 38 is preferably integral with paint splatter shield 22 and is adjacent to paint splatter shield back edge 32. It is also preferred that manifold 38 is positioned to direct a curtain of liquid against roller pad 13, preferably tangentially, to wash roller pad 13 and cover 20 after painting. Liquid manifold 38 comprises a tubular section 40 having a length approximately equal to side wall 24, a hollow interior 42, a closed lower end 44, and an upper end 46 adapted for attachment to a hose 48. FIG. 3 also shows a paint splatter shield interior 50, wherein tubular section 40 includes a plurality of spaced, longitudinally aligned holes 52 in communication with shield interior 50, whereby liquid is capable of flowing from tubular section upper 46 through hollow interior 42 for discharge through holes 52. A plurality of index notches 47a, 47b, and 47c located in paint shield inner surface 26 correspond to wash positions. The fast cleaning position corresponds to index notch position 47a, while medium and slow wash positions correspond to index notches 47b and 47c.

The integral structure of splatter shield 22 lends itself to efficient and cost effective injection molding manufacturing. An injection-molding plug 45 is used to plug an injection hole left in end 44 as a result of an injection molding process during manufacture.

FIG. 4 illustrates rinse splatter shield 54, which is rotatably mountable within the paint splatter shield 22. Rinse splatter shield 54 includes a semi-cylindrical side wall 56 having an axis of curvature about a central axis 25. The radius of curvature of side wall 56 is less than that of side wall 24 so that side wall 56 is rotatable beneath side wall 24. Preferably, the radius of curvature of the inner surface of side wall 24 is approximately equal to the radius of curvature of the outer surface of side wall 56. Rinse shield 54 also includes end walls 58 and 60.

Bushings 62 and 64 on end walls 58 and 60, respectively, are rotatably mountable in bushing receivers 66 and 68 of FIG. 3. Bushing 68 is adapted to engage the end of handle 16 adjacent spindle 12. Bushing 68 includes a side opening or V groove through which the beginning of handle 16 can be removed or inserted in order to change roller pads. In other embodiments, either or both bushings could include a side opening or both bushings could exclude a side opening.

Rinse splatter shield 54 has a leading edge 70 and a trailing edge 72 as well as an interior surface 74 and an exterior surface 74a. A stop tab 78 is located along leading edge 70. Referring back to FIG. 3, a first lock notch 80 is located on paint splatter shield front edge 32. A second lock notch 76 is engaged by stop tab 78 of FIG. 4 while the rinse splatter shield is in its rinse position. The first lock notch 80 is located along paint splatter shield front edge 32 and is engaged by rinse splatter shield stop tab 78 whenever rinse splatter shield 54 is in its stored position. A thumb tab 73 is located on the exterior surface of rinse splatter shield 54 near its trailing edge 72. Thumb tab 73 helps a user grip rinse splatter shield 54 while moving rinse splatter shield 54 from one of its positions to another. A stop tab 75 is lockable with index notches 47a, 47b and 47c, corresponding to the fast, medium and slow washing positions, respectively.

FIG. 5 shows a perspective view paint cover 20 along with a cover handle 90 that is attachable to the middle of paint splatter shield 22. Handle 90 has a hollow proximal end 92 for receiving the end of an extension pole (not shown). Handle 90 also includes a rearward curving brace 94 that follows the curvature of cover 20, and ends as a fold around cover back edge 30, and a forward brace 96 that follows the curvature of cover 20 ending as a partial wrap around a substantial portion of the circumference of tube 40 of liquid manifold 38. Since detachable cover handle 90 is located in the middle of cover 20 both right and left-handed users can use it. Therefore, it is possible to manufacture the handle cover combination shown in FIG. 5 in a one step injection molding process, which brings down the cost to a sellable price. A pair of roller pad end caps 98 are used to rotatably mount a roller pad to paint splatter shield 22 since an arm and spindle type roller is not used when detachable handle 90 is attached to paint splatter shield 22.

FIG. 6 shows a side view of paint cover 20 and attached handle 90 wherein rinse splatter shield 54 is in its stored position. In its stored position during painting, most of rinse splatter shield 54 is beneath paint splatter shield 22.

FIG. 7 shows a side view of paint cover 20 and attached handle 90 wherein rinse splatter shield 54 is in its rinse position. In its rinse position most of rinse splatter shield 54 extends outside paint splatter shield 22. The rinse splatter shield rinse position is used whenever roller pad 13 needs to be substantially, but not completely, enclosed to prevent a rinse solution of diluted paint from slinging or splattering while a curtain of liquid is directed against paint roller pad 13.

Referring back to FIG. 2, paint splatter shield 22 also includes a paint extraction tool 100 for removing excess paint from roller pad 13 before washing. Paint extraction tool has a handle 102 and a blade 104, wherein blade 104 has a semi-circular edge 106, sized to receive a substantial arc-length of the circumference of roller pad 13. When attached to paint splatter shield 22, a gripping tab 108 that projects outwardly from paint splatter shield 22 holds paint extractor tool 100.

Certain modifications and improvements will occur to those skilled in the art upon a reading of the foregoing description. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
