     BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to painting accessories, and more particularly to a painting implement that assists in diverse operations of hand painting, such as opening the can, mixing and stirring paint solutions, as well as aiding in cleaning the used paint roller, can and can lip.  
         [0004]     2. Description of the Prior Art  
         [0005]     Painting by hand, particularly building walls and partitions and other large objects, requires different tools such as brushes and rollers for applying paint to surfaces being painted. When a painter interrupts his or her work for any reason, it is a wise precaution to clean brushes and rollers so that paint will not dry and cake thereon. Frequently this is done by wiping brushes and even rollers on a convenient surface, such as the inner flange of a paint can. However, wiping leaves a considerable amount of paint on the brush or roller.  
         [0006]     The prior art has taken note of the problem of efficient cleaning paint supplies, and has proposed apparatus to expedite cleaning. The prior art as seen in U.S. Pat. No. 3,925,908 (issued to Kirkley J. Dunn on Dec. 16, 1975); U.S. Pat. No. 6,012,473 (issued to Takehiko Koyama on Jan. 11, 2000); U.S. Pat. No. 3,460,268 (issued to Carl F. Greathouse on Aug. 12, 1969); U.S. Pat. No. 4,545,395 (issued to Kolb on Oct. 8, 1985); U.S. Pat. No. 5,984,518 (issued to King et al. on Nov. 16, 1999); and U.S. Pat. No. 2,931,661, (issued to Joseph N. Harris on Apr. 5, 1960) as cited in the previous parent application Ser. Nos. 09/621,079 and 10/283,131 are all incorporated herein as reference.  
         [0007]     The prior art is replete with devices designed to address the problems of adequate paint mixing as shown in the references to Cooke (U.S. Pat. No. 4,054,272), Silverman (U.S. Pat. No. 2,799,485), Gibson (U.S. Pat. No. 1,841,435); and Place (U.S. Pat. No. 2,896,925). These disclosed patents provide novel means of mixing paint solutions however none of these devices may also be used during the painting process serving as a paint solution mixer in addition to a paint roller cleaner.  
         [0008]     Additionally, U.S. Pat. No. 385,151, issued to George M. Thompson on Jun. 26, 1888, discloses an AGITATOR FOR CASKS OR BARRELS in which a paddle member is rotatably mounted to a shaft for agitating within a barrel after insertion through the bung hole of the barrel. Unlike Thompson, the stop means of the present invention allows the paddle member to travel only through a predetermined arc, preventing the paddle member from becoming fully parallel to the shaft.  
         [0009]     None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.  
       SUMMARY OF THE INVENTION  
       [0010]     The present invention sets forth a painting implement which enables the user to open paint cans, mix paint and to clean conventional paint rollers utilizing a hand drill, as well as cleaning the can lip of accumulated paint. The painting implement is selectively adjustable to be configured to mix paint and to support a paint roller for cleaning, thereby being capable of providing several functions. Implements of different diameters may be provided, for cleaning and using an assortment of sizes of paint rollers. The implement is provided with a paddle member that is perforated and of a geometric non-planar form to enhance mixing, as well as a paint can opener tab and a can lip cleaning tab.  
         [0011]     It is therefore an object of the invention to provide an implement for painting that performs several painting related functions including can opening, paint mixing, roller cleaning, can lip cleaning.  
         [0012]     It is another object of the invention that the implement engage a hand drill for imparting rotation for paint mixing, and cleaning of paint rollers.  
         [0013]     It is a further object of the invention that the implement engage paint rollers of different dimensions, thereby cooperating with standard painting tools.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0030]      FIGS. 1A and 1B  show the inventive, geometrically shaped painting implement  100 . As can be seen, the inventive painting implement  100  has a paddle member  10 , having a length, height and thickness, and ideally having slightly rounded lower corners  28  adapted to lessen the severity of any impacts between the corners of the paddle member and a container in which it is being used. The lower edge  13  of the paddle member  10  may be variously shaped to form a spatula to aid in the removal of paint from a paint can. The paddle member  10  is attached to a proximal end  20   p  of a rod shaft  20 , preferably at the center of the paddle member  10 , by a pivoting fastener  16 . The rod shaft  20  is typically cylindrical, transitioning to flattened, opposing faces at the proximal end  20   p,  thereby providing a flat interface between the rod shaft  20  and the face of the paddle member  10 . The fastener  16  may comprise any suitable means of connection, such as a rivet, bolt and nut, etc., which provides selective rotational movement of the paddle member  10  relative to the axis of the rod shaft  20  allowing the paddle member  10  to move between two positions, discussed further below.  
         [0031]     A plurality of perforations  12  are formed through the paddle member  10 , thereby allowing a viscous fluid (hereinafter referred to as paint, although it would be evident to one of ordinary skill in the art that the implement  100  could be used for stirring other viscous fluids, such as sheetrock mud or spackling) being stirred to pass therethrough, increasing the agitation rate of the paint. The apertures  12  may be formed at differing angles from one another as they pass through the thickness of the paddle member  10 , further aiding in more thorough mixing.  
         [0032]     Additionally, a portion of each end of the paddle member  10  is deflected from the plane in which the rest of the paddle member  10  lies. The line of each of the two deflections  14  typically extends from a lower corner  28  of paddle element  10  to a point between the corresponding upper corner  30  and a midpoint between the two upper corners  30 . The two deflections  14  extend, respectively, to opposite sides of the plane of the paddle member  10  from one another, such that as the paddle member  10  rotates around the rod shaft  20  in a clockwise rotation, each of the two deflections  14  precedes the plane of the paddle member  10 , thereby aiding in cutting into the paint as the paddle member  10  rotates, creating a wave action in the paint as it is stirred. It would be evident to one of ordinary skill in the art that the exact shape of the deflections  14  could vary or that paddle member  10  could be formed without the deflections  14  without departing significantly from the spirit of the present invention.  
         [0033]     A stop nub  18  extends outwardly from the surface of paddle member  10  to one side of shaft rod  20 , at a point proximate the proximal end  20   p  of shaft rod  20 , below the pivoting fastener  16 . The stop nub  18  limits the rotation of the paddle member  10  about the pivoting fastener  16  to an arc, typically less than 90°, by engaging the shaft rod  20  such that paddle member  10  may rotate between a position that is substantially normal to shaft rod  20  or substantially parallel to shaft rod  20 , although preferably at a slight angle from truly parallel, as will be further detailed below. Stop nub  18  has rounded shoulders which allows a user to vary the tightness of the connection between the stop nub  18  and the rod shaft  20  by twisting the paddle to varying degrees, thereby affecting whether or not, and how much, stop nub  18  passes under the rod shaft.  
         [0034]     In the preferred embodiment, the upper corners  30  of the paddle member  10  are cut on a diagonal, as opposed to the rounded lower corners  28 . Extending from a first of the diagonal upper corners is a substantially rectilinear paint can opener  22  protrusion dimensioned and configured to fit under the rim of a paint can lid (not shown) to pry it open. The can opener protrusion  22  extends at a slight angle from the plane of the deflection  14 . Extending from the second of the diagonal upper corners is a second substantially rectilinear lip cleaner  24  protrusion dimensioned and configured to fit within the rim lip (not shown) of a paint can to aid in the removal of paint accumulated in the rim lip (not shown).  
         [0035]     In an alternative embodiment, rather than shaft rod  20  being attached to the paddle member  10  on one side of paddle member  10 , paddle member  10  can be formed with a groove  26  along the upper edge thereof ( FIG. 3 ), the end of rod shaft  20  being rotatably affixed therein by a pivot fastener  16  such that as the paddle member  10  is rotated about the pivot fastener  16  to the substantially parallel position, the rod shaft  20  fits into the groove  22 , the walls of the groove  26  acting in lieu of the stop nub  18 .  
         [0036]     As stated, the inventive painting implement  100  may be set at two functionally distinct positions depending on the operation being performed with paddle member  10 .  FIGS. 1A and 1B  illustrate the first, lateral or normal position, which is employed when the implement  100  is used as a mixer/stirrer in larger paint containers (typically 1 gallon and larger). As shown in  FIGS. 4A, 4B  and  6 , the rod shaft  20  is an elongated, rigid shaft for coupling the paddle member  10  to an electrically operated hand drill  50 . It would be evident to one of ordinary skill in the art that the shaft  20  could be grasped in the hand and the implement used as a hand-held stirring device without departing from the spirit of the present invention.  
         [0037]      FIGS. 2A and 2B  illustrate the painting implement  100  in a second, substantially linear or parallel position wherein the paddle member  10  is positioned substantially parallel to, but with an offset of an acute angle with respect to the rod shaft  20  (described further below). In this second position, the implement  100  functions as an element for mixing/stirring in a smaller container (typically 1 gallon or 1 quart), mixing/stirring thinner fluids in order to prevent excessive splashing which could be caused by using the first position, or for supporting a paint roller for cleaning (described below).  
         [0038]      FIGS. 4A &amp; 4B  show the implement  100  in use stirring paint  42  within a paint container  40 . The arrows indicate movement currents of the paint  42  as it is being mixed. The perforations  12  within paddle member  10 , in conjunction with the deflections  14  of paddle member  10 , both play a major part in further assisting with the mixing (i.e., stirring motion) of the paint  42  when the paddle is in motion. Additionally, paint may be stirred in a larger, unopened container by inserting the paddle member  10  through the bung hole (not shown) of the lid (not shown) of the container with the paddle in the second, linear position. Centrifugal force may cause the paddle member  10  to open to the lateral position of  FIG. 1A , or it may be used in the linear position.  
         [0039]     Additionally, this second position may also be employed to assist with the cleaning of a paint roller  60 , as shown at  FIGS. 5 and 6 . For the purpose of cleaning the roller  60 , the paddle member  10  is inserted into the interior wall  62  of paint roller  60 , in the linear configuration of  FIGS. 2A and 2B , with the slight deviation from the rod shaft  20  allowing the paddle member  10  and the rod shaft  20  to engage the interior of the paint roller  60  to frictionally hold the paint roller  60  on the implement  100 . As shown in  FIG. 6 , paint roller  60  may be inserted in a container  70  containing a cleaning solution  72 . A hand drill  50  coupled to the paddle member  10  (by way of a distal end  20   d  of shaft  20 ) spins the roller  60 , as indicated by arrow  75 . The centrifugal forces produced by the offset shape of the paddle member  10  during the spinning aids in the removal of paint embedded within the fibers of roller  60  by producing a whipping action. This oscillation greatly enhances the cleaning process.  
         [0040]     In addition to being cleaned in a container, the paint roller  60  may be sprayed from a nozzle head (not shown) as the hand drill  50  rotates the element  100  and paint roller  60 .  
         [0041]     The present invention is susceptible to variations and modifications which may be introduced thereto without departing from the inventive concept. For example, paddle member  10  may be removable from rod shaft  20 , rather than having a rivet at pivot fastener  16 . Instead, paddle member  10  could be retained by friction in the two operative positions, if desired. Additionally, the size of the paddle member  10  may vary so that it may be usable with paint rollers  60  of different dimensions. The paddle member  10  may have edges formed in a beveled manner, as well, to facilitate other uses of the paddle  10 , such as scraping the interior of paint cans, etc. Furthermore, while a rigid paddle member  10  is preferred, a flexible paddle member  10  may also be utilized, allowing for more flexibility as a spatula for removing paint from a can.  
         [0042]     In alternative embodiments, the rod shaft  20 A may have an offset  21  along its length ( FIG. 7 ), proximate the proximal end  20   p.  The paddle member  10  is mounted within the offset  21 , which aids in maintaining a center of balance for the implement  100  which lies more along the axis of the shaft  20 A, thereby reducing any wobble which would be caused by the blade  10  being attached to one side of the shaft.  
         [0043]     At  FIG. 8 , the rod shaft  20 B may have a broad shaft paddle  21  formed therein. The shaft paddle  21  may either have a twist, as shown, or be flat (not shown). The shaft paddle  21  increases the agitation of the paint  42  beyond that of the paddle member  10 . Additionally, the upper  13  and lower  15  edges of the paddle member  10  may be more flexible than the body of the paddle member  10 , thereby providing additional gripping of the interior of a paint roller  60  when it is inserted therein.  
         [0044]     It would be evident to one of ordinary skill in the art that the implement  100  of the present invention may be formed in a variety of ways, including extrusions and injection molding, of a variety of materials, and metals and polymers, and in a variety of material weights, from light for paints, to heavy for thicker fluids, such as sheet rock compound.  
         [0045]     It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
