Description:
REFERENCE TO RELATED APPLICATION 
     This application claims priority to Provisional Applic. No. 62/518,153, filed on Jun. 12, 2017, the contents of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The present invention generally relates to paint application devices. More particularly, the invention relates to a painting apparatus and method of use in connection with painting within narrow spaces. 
     BACKGROUND OF THE INVENTION 
     In certain situations it is desirable to mount objects close to surfaces to minimize the portion of the location in which the object is located that is occupied by the object. An example of one such object is a toilet. It is possible to mount the toilet close to a wall because it is generally not necessary to access the portion of the wall that is behind the toilet. 
     One of the primary times that it is necessary to access the space behind the toilet is when decorating. For example, it is generally desirable to paint the space behind the toilet when painting other portions of the wall that are not behind the toilet. 
     While conventional painting implements such as rollers and paint brushes may be used on the other portions of the wall that are not behind the toilet, the toilet is typically located sufficiently close to the wall such that it is not possible to access all of the space that is behind the toilet with a conventional roller or paint brush. 
     To overcome this limitation, it is common to disconnect at least a portion of the toilet to facilitate painting behind the toilet. A problem with disconnecting a portion of the toilet is that it may be necessary to have the portion of the toilet disconnected by a plumber because the toilet contains water and drain lines. Any water and/or waste that inadvertently escapes from the toilet may not only cause damage to the areas that surround the toilet, but also could present a health risk. 
     A need exists for improvement in paint application devices. This need, and other needs, is addressed by one or more aspects of the present invention. 
     SUMMARY OF THE INVENTION 
     An embodiment of the invention is directed to an elongated painting apparatus that includes a paint applicator holder, a paint applicator and a lock mechanism. The paint applicator holder has a handle portion and an applicator portion that extends from a distal end of the handle portion. The paint applicator is detachably engagable with the applicator portion. The lock mechanism has a first engagement structure, a second engagement structure and an opening. The first engagement structure and the second engagement structure are provided in one of the applicator portion and the paint applicator. The opening is formed in one of the applicator portion and the paint applicator where the first engagement structure and the second engagement structure are not located. The first engagement structure and the second engagement structure are selectively received in the opening to retain the paint applicator in a first position or a second position with respect to the paint applicator holder. 
     Another embodiment of the invention is directed to an elongated painting apparatus that includes a paint applicator holder, a paint applicator and a lock mechanism. The paint applicator holder has a handle portion and an applicator portion that extends from a distal end of the handle portion. The paint applicator is detachably engagable with the applicator portion. The lock mechanism has an engagement structure, a first opening and a second opening. The engagement structure is provided in one of the applicator portion and the paint applicator. The first opening and the second opening are formed in one of the applicator portion and the paint applicator where the engagement structure is not located. The engagement structure is selectively received in either the first opening or the second opening to retain the paint applicator in a first position or a second position with respect to the paint applicator holder. 
     Another embodiment of the invention is directed to a method of painting a surface having an object in close proximity thereto. An elongated painting apparatus is provided that includes a paint applicator holder, a paint applicator and a lock mechanism. The paint applicator holder has a handle portion and an applicator portion that extends from a distal end of the handle portion.

     DETAILED DESCRIPTION OF THE INVENTION 
     An embodiment of an elongated painting apparatus  10  according to an embodiment of the present invention is illustrated in the drawings submitted herewith. The painting apparatus  10  aids in the application of paint to surfaces that are blocked or obstructed by objects placed close to the surfaces, such as toilets, stoves and refrigerators. Many such objects are very heavy or permanently mounted, and therefore difficult or impossible to move. 
     The elongated painting system  10  includes a paint applicator holder  14  and a paint applicator  12  that is operably attached to the paint applicator holder  14 . As illustrated in  FIGS. 1 and 2 , the paint applicator holder  14  includes a handle portion  20  and an applicator portion  22 . 
     In certain embodiments, the handle portion  20  includes an elongated region configured to be grasped by a user of the elongated painting apparatus  10 . The elongated region may be formed with a length, width and outer surface contour to at least partially conform to the shape of the user&#39;s hand when closed. 
     The handle portion  20  includes several features that enhance the ability to hold onto the handle portion  20  if part of the handle portion  20  is at least partially covered with paint, which can reduce the ability to grasp the handle portion  20 . 
     The handle portion  20  may generally be defined as including a proximal section  40 , an intermediate section  42  and a distal section  44 . In certain embodiments, the proximal section  40 , the intermediate section  42  and the distal section  44  may be integrally formed. 
     The proximal section  40  may have a maximum width and/or a maximum height that is larger than a maximum width and/or a maximum height of the intermediate section  42 . Forming the proximal section  40  with the maximum width and/or the maximum height that is larger than the maximum width and/or the maximum height of the intermediate section  42  reduces the potential of the user&#39;s hand slipping off of the end of the elongated painting apparatus  10  because even if the user&#39;s hand is held slightly larger than the intermediate section  42 , the user&#39;s hand will encounter the wider and/or higher proximal section  40  and thereby be prevented from sliding off the handle portion  20 . 
     Forming the proximal section  40  with the maximum width and/or the maximum height that is larger than the maximum width and/or the maximum height of the intermediate section  42  also enables the user to sense the position of the user&#39;s hand on the handle portion  20  without the user having to view the position of the hand on the handle portion  20 . 
     At least one of the top surface and the bottom surface of the handle portion  20  may include a non-smooth transition (not shown) between the proximal section  40  and the intermediate section  42 . In certain embodiment, the non-smooth transition is a ridge on the upper surface. 
     The non-smooth transition enhances the ability of the user to sense the position of the user&#39;s hand on the handle portion  20  without the user having to view the position of the hand on the handle portion  20 . 
     The intermediate section  42  may encompass up to about 80 percent of a length of the handle portion  20 . In certain embodiments, the intermediate section  42  encompasses between about 40 percent and about 80 percent of the length of the handle portion  20 . 
     The handle portion  20  may be fabricated from the same material as the other components of the elongated painting apparatus  10 . Alternatively, the handle portion  20  may be fabricated from a material such as molded plastic. 
     The applicator portion  22  has a first surface  30  and a second surface  32  that are oriented opposite each other. In at least one embodiment, the first surface  30  is substantially flat and is adapted to receive the paint applicator material  12 . It will further be appreciated that various embodiments of the applicator portion  22  are of varying lengths. 
     The length of the applicator portion  22  depends on the size of the object behind which the user desires to paint. In certain embodiments, the applicator portion  22  is between about 12 inches and about 18 inches. However, other embodiments may feature an applicator portion  22  as short as about 6 inches and as long as about 36 inches. 
     Depending on the length of the applicator portion  22  and the material from which the applicator portion  22  is formed, it may be necessary to strengthen the applicator portion  22  to ensure that an end of the applicator portion  22  that is opposite the handle portion  20  is sufficiently rigid to cause the paint to be applied to the surface. 
     An example of one such device that may be used to strengthen the applicator portion  22  is at least one rib  34  that extends from the second surface  32  along at least a portion of a length of the applicator portion  22 . 
     The applicator portion  22  may be formed with a width that depends on factors such as the size of the object behind which it is desired to paint and the volume of paint that is desired to be held with the paint applicator  12 . For example, the wider the paint applicator  12 , the more paint that may be held in the paint applicator  12 , which reduces the frequency at which the paint applicator  12  must be refilled with paint. In at least one embodiment, the width of the applicator portion  22  is about 6 inches. In alternative embodiments, the width is smaller, even as small as about 1 inch. 
     Proximate the intersection of the applicator portion  22  and the intermediate portion  24 , a stop mechanism  36  may extend therefrom. The stop mechanism  36  limits a distance to which the paint applicator  12  may be inserted over the applicator portion  22 . A person of skill in the art will appreciate that the stop mechanism  36  may assume a variety of configurations using the concepts of the invention. 
     The applicator portion  22  may be formed from a variety of materials using the concepts of the invention. In some embodiments, the applicator portion  22  may be formed from a metallic material such as stainless steel. Forming the applicator portion  22  from stainless steel enables the applicator portion  22  to be relatively rigid and relatively thin. 
     The intermediate portion  24  may offset the handle portion  20  from the applicator portion  22  such that when the applicator portion  22  is positioned along a surface for applying paint to the surface, the handle portion  20  is located above the surface such that the user&#39;s hand does not contact the surface and thereby contact the wet paint. 
     In some embodiments, the offset between the handle portion  20  and the applicator portion  22  is up to about 6 inches. In other embodiments, the offset between the handle portion  20  and the applicator portion  22  is between about 1 inch and about 3 inches. 
     The intermediate portion  24  may be oriented at an angle with respect to the applicator portion  22 . In some embodiments, the angle may be between about 20 and about 90 degrees. 
     The handle portion  20 , the applicator portion  22  and the intermediate portion  24  may be oriented in different configurations. Examples of alternative configurations provide the painting apparatus  10  with a C-shape or an L-shape. 
     The intermediate portion  24  may be integrally formed with at least one of the handle portion  20  and the applicator portion  22 . The intermediate portion  24  may have sufficient rigidity such that when a pressure is applied to the applicator portion  24  with the handle portion  20 , the intermediate portion  24  resists deformation. 
     The paint applicator  12  may be formed with a size and a shape that is similar to the size and shape of the applicator portion  22 . A distal end of the paint applicator  12  may be curved. Extending from opposite sides on a back side of the paint applicator  12  are arms  60 . These arms  60  extend partially around the applicator portion  22  to retain the paint applicator  12  on the applicator portion  22 . 
     The elongated configuration of the paint applicator  12  minimizes the amount of paint in the paint applicator  12  to paint the surface that is at least partially behind an object that is a relatively small distance from the surface to which the paint is applied. In certain embodiments, a distance between the object and the surface to which the paint is applied is less than about five inches. In other embodiments, the distance between the object and the surface to which the paint is applied is less than about two inches. As used herein, the term elongated means that the paint applicator has a length that is at least about four times longer than a width. 
     The paint applicator  12  may be formed from a variety of materials using the concepts of the invention such that the paint applicator  12  is relatively thin and has the ability to absorb paint to facilitate applying the paint to the surface. In some embodiments, the paint applicator material may be foam, bristles, fabric or some combination thereof. 
     In some embodiments, the paint applicator  12  has a paint applicator material that is consistent over the entire surface thereof. In other embodiments, the paint applicator  12  may have at least two applicator regions that are fabricated from different materials. 
     The paint applicator  12  may be attached to the applicator portion  22  using a variety of techniques. In some embodiments, the paint applicator  12  is permanently attached to the applicator portion  22 . Using such a configuration, the elongated painting apparatus  10  may be disposed of after use. 
     In other embodiments, the paint applicator  12  may be removably attached to the applicator portion  22 . An example of suitable techniques for removably attaching the paint applicator  12  is an adhesive or a hook and loop fastener such as is available under the designation VELCRO. 
     Alternatively or additionally, a portion of the paint applicator  12  may extend over at least a portion of the applicator portion  22  such that sliding of the paint applicator  12  with respect to the applicator portion  22  facilitates attachment or detachment of the paint applicator  12  to the applicator portion  22 . 
     In such a configuration, a lock mechanism may be provided to retain the paint applicator  12  in a desired location with respect to the applicator portion  22 . The lock mechanism includes an engagement structure  38  and an opening  62 . In certain embodiments, the engagement structure  38  is on the applicator portion  22  and the opening  62  is on the paint applicator  12 . 
     The engagement structure  38  extends below a lower surface of the applicator portion  22 . In certain embodiments, the engagement structure  38  has an elongated shape. In other embodiments, the engagement structure  38  may be formed with a non-elongated shape. 
     In certain embodiments, a height of the engagement structure  38  proximate a proximal end thereof may be greater than a height of the engagement structure  38  proximate a distal end thereof to facilitate sliding the paint applicator  12  over the engagement structure  38 . 
     The engagement structure  38  has a top panel  50  and a proximal panel  52  at a proximal end thereof. The proximal panel  52  is oriented at an angle with respect to the top panel  50 . In certain embodiments, the angle is between about 10 degrees and about 90 degrees. 
     The opening  62  is adapted to receive at least a portion of the engagement structure  38 . In certain embodiments, the opening  62  has a length and a width that are similar to but larger than the length and the width of the engagement structure  38 . 
     Seating of the engagement structure  38  in the opening  62  causes the paint applicator  12  to resist being separated from the applicator portion  22  such as when the painting apparatus  10  is moved along the surface of a wall to apply paint to the wall. 
     When it is desired to separate the paint applicator  12  from the applicator portion  22 , at least one of the applicator portion  22  and the paint applicator  12  has sufficient flexibility to deflect when it is desired to remove the paint applicator  12  from the applicator portion  22  by sliding the paint applicator  12  towards the distal end of the applicator portion  22 . 
     A person of skill in the art will appreciate that it is possible to reverse the location of the opening and the engagement structure so that the opening is formed in the applicator portion  22  and the engagement structure extends from the paint applicator  12 . 
     In certain situations, it may be desirable for paint to be applied to a surface that is located further than can be reached when the paint applicator  12  is fully extended onto the paint applicator holder  14 , as illustrated in  FIG. 6 . In such a situation, more than one engagement structure  38  may be provided on the applicator portion  22 . The engagement structures  38  may be provided in a spaced-apart configuration. 
     When the paint applicator  12  is fully inserted on the paint applicator holder  14 , as illustrated in  FIG. 6 , the opening engages the first engagement structure  38   a . When the paint applicator  12  is partially inserted onto the paint applicator holder  14 , as illustrated in  FIGS. 7 and 8 , the opening  62  engages the second engagement structure  38   b  that is located closer to the distal end of the applicator portion  22 . Such engagement restricts the paint applicator  12  from sliding off of the applicator portion  22 . 
     A person of skill in the art will appreciate that the concepts of the invention may be modified to utilize more than two engagement structures. Alternatively or additionally, the invention may be modified to utilize more than one opening. 
     When the paint applicator  12  is in the partially inserted configuration illustrated in  FIGS. 7 and 8 , the distal end of the paint applicator  12  may have a greater amount of flexibility as compared to when the paint applicator  12  is fully inserted onto the applicator portion  22 . Such flexibility may decrease the ability of the distal end of the paint applicator  12  to make sufficient contact with the wall to cause paint to be applied to the wall. 
     When it is anticipated that the paint applicator  12  may be used in the partially inserted configuration, the paint applicator  12  may be formed with enhanced structural rigidity to enhance the likelihood that the distal end of the paint applicator  12  will make sufficient contact with the wall to cause paint to be applied to the wall. 
       FIG. 9  illustrates the use of the painting system  10  in conjunction with applying paint to a wall surface  101  that is located behind an object  100  such as a toilet, which is located relatively close to the wall surface  101  such as to make it difficult to paint the wall surface  101  behind the object  100  using a conventional paint brush or a paint roller.
