Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     This invention relates to tools and more particularly relates to guards for preventing surface exposure to paint.  
         [0003]     2. Description of the Related Art  
         [0004]     When painting walls, furniture, or the like, painters often use a variety of tools or mechanisms to prevent paint from contacting nearby surfaces, such as the trim next to a wall. Painters frequently use tape, paint shields, special brushes or rollers and the like to direct the paint to the desired surface and to prevent undesired contact with adjoining surfaces. These mechanisms generally work well for large level surfaces such as base boards and window panes.  
         [0005]     Uneven paint surfaces with small protrusions or indentations, however, present additional problems when painting. First, paint shields and/or brushes usually are not sized to accommodate such conditions, generally leaving the protrusion and/or indentation unprotected during the painting process. Second, tape, which is flimsy and somewhat difficult to apply, can leave a sticky residue and usually does not sufficiently cover uneven surfaces. An example of a protrusion may be a hinge, and an example of an indention may be a mortise.  
         [0006]      FIG. 1  depicts an exploded view of one embodiment of a standard hinge  100  and a hinge mortise  110 . The hinge  100  generally includes a plurality of leaves  102 , a joint  104  and/or pin connecting the leaves  102 , holes  106 , and a curved or decorative edge  108 . The holes  106  may facilitate attaching the hinge  100  with a fastener to a surface  120  of an object, such as a door, door jamb, table or the like.  
         [0007]     The mortise  110 , which generally consists of a cut out cavity or an indentation  112  in the surface  120 , corresponds to the leaf  102 , as illustrated, and includes holes  114  that match up with the holes  106  of the hinge  100 . A fastener (not shown) such as a screw or bolt may be inserted through the holes  106  and secured within the mortise holes  114 . The mortise  110  enables the surface  120  to remain substantially flat when the hinge  100  is secured within the mortise  110 .  
         [0008]     Painting around the hinge  100  generally introduces some of the problems mentioned above. A paint shield is typically not sized to fit around the joint  104 , and tape, if applied to the whole hinge  100 , is usually difficult to apply and does not provide a well-defined edge. Paint additionally tends to seep between the hinge  100  and the mortise  110 , essentially gluing the hinge  100  to the mortise  110  permanently, which may not be desirable.  
         [0009]     As an alternative to covering the hinge  100 , the hinge  100  may be removed to prevent contact with the paint. The mortise  110 , however, may be susceptible to damage from the paint. In certain instances, paint accumulated within the mortise  110  fills in the indentation  112 , thus deforming the mortise  110  and preventing proper insertion of the leaf  102 . Particularly in situations where the hinge  100  is positioned between a door and a door jamb, a mal-fitted hinge  100  may cause the door to stick or may even prevent closing the door.  
         [0010]     From the foregoing discussion, it should be apparent that a need exists for an apparatus and method that preserve a mortise by preventing paint from entering the mortise. Beneficially, such an apparatus and method would enable the removal and reinsertion of the corresponding element, such as the hinge  100 , would provide a well-defined edge for painting the surface around the mortise, and would provide a temporary, non-damaging shield such that the corresponding element may be completely restored to its original configuration subsequent to the painting process.  
       SUMMARY OF THE INVENTION  
       [0011]     The present invention has been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available paint guards. Accordingly, the present invention has been developed to provide an apparatus and method for preserving a mortise that overcome many or all of the above-discussed shortcomings in the art.  
         [0012]     The apparatus, in one embodiment, comprises a guard with an overlay configured to fill a mortise, an edge conforming to an indentation edge of the mortise, and a securing device for securing the overlay within the mortise. The guard prevents paint from entering and damaging the mortise. In certain embodiments, the overlay may be shaped to resemble the leaf of a hinge. In addition, the overlay may comprise a flange to facilitate insertion of the overly within the mortise. In one embodiment, the overlay comprises a textured surface configured to prevent paint from running off of the overlay.  
         [0013]     The securing device may be configured to retain the overlay within the mortise. In one embodiment, the securing device comprises a hole for receiving a fastener. In another embodiment, the securing device comprises a protrusion connected to the overlay. The protrusion may have flexible ridges to secure the protrusion within the hole of the mortise. In certain embodiments, the protrusion comprises an elastomeric plug. In yet another embodiment, the securing device comprises a fastener such as one or more staples, nails, screws, or the like. In a further embodiment, the hole is adapted to interchangeably receive an insert, such that the insert provides a protrusion or a flat plug that blocks the hole. In addition the securing device may comprise an adhesive or the like. Consequently, the overlay may be secured within the mortise during the painting process.  
         [0014]     A method of the present invention is also presented for preserving a mortise. In one embodiment, the method includes providing a guard, placing the guard on top of the mortise, and securing the guard within the mortise. The method also may include painting around the guard and removing the guard from the mortise. Furthermore, the method of the present invention may comprise reusing the guard for preserving a second mortise.

       [0036]     Reference throughout this specification to “one embodiment,” “an embodiment,” or similar language means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases “in one embodiment,” “in an embodiment,” and similar language throughout this specification may, but do not necessarily, all refer to the same embodiment.  
         [0037]     Furthermore, the described features, structures, or characteristics of the invention may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.  
         [0038]      FIG. 2  illustrates one embodiment of a guard  200  for preserving the mortise  110  of  FIG. 1 . In the depicted embodiment, the guard  200  includes an overlay  202 , an edge  204 , a securing device  206 , a flange  208 , a textured surface  210 , and a symbolic element  212 . The guard  200  may be sized to resemble the corresponding element that fits within the mortise  110 , such as the hinge leaf  102  in the illustrated embodiment. In one aspect, the guard  200  may resemble a “dummy” corresponding element to prevent paint from filling in the indentations  112  or from contacting the mortise  110 . The guard  200  may have any size or shape to correspond to the mortise  110 .  
         [0039]     In the depicted embodiment, the overlay  202  is a thin, rectangular plate with a lip-like fin or flange  208  extending at an obtuse angle from one side. The flange  208  extends the length of the overlay  202 . The opposing side of the overlay  202  has a straight edge  204  that transitions at radial corners to perpendicular top and bottom edges  204 . The securing device  206  comprises a countersink hole disposed centrally within the overlay  202 . The counter sink hole may be positioned centrally relative to the length of the overlay  202 . In one embodiment, given by way of example, the overlay  202  is 1.125 inches wide by 3.480 inches long.  
         [0040]     The overlay  202  may be made from any material suitable for preventing paint from contacting the mortise  110 . In certain embodiments, the overlay  202  may be a rigid or semi-rigid material. In one embodiment, the overlay  202  is made from a biodegradable plastic. In an alternative embodiment, the overlay  202  may be made of an elastomeric material or rubber. In a contemplated embodiment, the overlay  202  may be made from wood or metal. Those of skill in the art will recognize that suitable materials are not limited to those described.  
         [0041]     The guard  200  may be intended for single use or may be reusable. The material may be selected to resist paint accumulation such that the user may be able to easily clean the guard  200 . Alternatively, the guard  200  may be disposable.  
         [0042]     As mentioned, the overlay  202  may be sized to match to the corresponding element of the mortise  110 . Consequently, the edge  204  of the overlay  202  may correspond to the edge  108  of the leaf  102  or the like in order to create a tight fit within the mortise  110 .  
         [0043]     In certain embodiments, the edge  204  may be formed into a variety of shapes to fit a specific mortise  110 . In one embodiment, the overlay  202  is made from a semi-rigid material that may be cut with a razor or the like, thereby enabling the user to shape the edge  204  to correspond with a specific mortise  110 . In certain embodiments, the overlay  202  may comprise multiple sections that fit together to fill the mortise  110 . Those of skill in the art will recognize that the overlay  202  may be constructed from a variety of materials and that the edge  204  may be formed or modified using a variety of methods.  
         [0044]     The guard  200  may further include the securing device  206  to secure the overlay  202  within the mortise  110 . In the depicted embodiment, the securing device  206  comprises a hole  206  disposed within the overlay  202  that is substantially aligned with the hole(s)  114  of the mortise  110 . As a result, the guard  200  may be secured to the mortise  110  with a fastener such as a screw or the like.  
         [0045]     Alternatively, the overlay  202  may comprise one or more protrusions, which will be discussed in greater detail with relation to  FIGS. 7-19 . In one embodiment, the overlay  202  is flat and is secured to the mortise  110  with a nail, staple, adhesive or the like, which will be discussed with relation to  FIG. 15 .  
         [0046]     In a contemplated embodiment, the securing device  206  enables the guard to be easily secured to and removed from the mortise  110  without permanently altering the mortise  110 . In addition, the securing device  206  and/or the guard  200  preferably do not obstruct or cover the surface  120  designated to be painted. In certain embodiments, the overlay  202  may be secured with an adhesive or the like, in addition to or in place of another type of fastener. In one embodiment, the back of the overlay  202  may be coated with an adhesive or bonding agent, which may be protected by a peel-off backing.  
         [0047]     The flange  208  may be disposed on the overlay  202  and may facilitate insertion and removal of the guard  200  by providing a handle or grip for the user. In certain embodiments, the flange  208  extends the length of the overlay  202 . Alternatively, the flange  208  may span a portion of the overlay  202 . In one embodiment, the flange  208  is attached to the top surface of the overlay  202 . The flange  208  may be molded with the overlay  202  in certain embodiments. Alternatively, the flange  208  may be made separately and may be attached to the overlay  202 .  
         [0048]     In one embodiment, the flange  208  is removable and may include a fastener such as a snap, hook, hook and loops, or the like. Those of skill in the art will recognize that the flange  208  may be made from a variety of materials and may be disposed on the overlay  202  in a variety of positions and/or configurations and is not, therefore, limited to the illustrated embodiments.  
         [0049]     The overlay  202  may include the textured surface  210  or the like to facilitate the painting process. The textured surface  210  may prevent paint from conglomerating and running or dripping onto the painted surface  120 . In one embodiment, the surface of the overlay  202  is coated with a textured residue. Alternatively, the surface of the overlay  202  may be roughened or imprinted with a textured pattern.  
         [0050]     The guard  200  may further include a symbolic element  212 , such as a logo, company information, labels, product discounts, instructions, etc., to present a message. In one embodiment, the symbolic element  212  is molded into the overlay  202 . In an alternative embodiment, the symbolic element  212  is printed on a label or the like and attached to the guard  200  after the manufacturing process. In certain embodiments, the symbolic element  212  enables the paint guard  200  to function as an advertisement to promote a business and/or its products.  
         [0051]      FIG. 3  illustrates one embodiment of a guard  300  with an overlay  302 , an edge  304 , a hole  306 , and a flange  308 . The overlay  302  may comprise a flat back surface  310  for contacting the mortise  110 . The hole  306  may comprise a countersink hole  306  that extends through the overlay  302  to facilitate securing the guard  300  within the mortise  110  with a fastener. In certain embodiments, the guard  300  may comprise any number of holes  306 , preferably not to exceed the number holes  114  in the selected mortise  110 . The hole(s)  306  may be any variety of types and/or sizes. Alternatively, the guard  300  may be flat without any holes  306 . In such an embodiment, the guard  300  may be attached with an adhesive and/or with staples, nails, self-tapping screws or the like. Likewise, the guard  300  may have hole(s)  306  adapted to interchangeably receive an insert. The insert could be a protrusion  706  of  FIG. 7 , a protrusion with flexible ridges  1106  of  FIG. 11 , an adhesive plug, or a flat plug designed to fill the hole  306 .  
         [0052]     In one embodiment, the guard  300  may be configured to fit within the mortise (not shown) of a door jamb designated for receiving the bolt of a door lock. In such an embodiment, the guard  300  may comprise a pair of holes  306  to align with the holes of the mortise. Alternatively, the guard  300  may comprise a protrusion and/or a tenon to fit into the bolt cavity as illustrated in  FIGS. 16-19 . The guard  300  may be configured to fit into a variety of mortises and is not, therefore, limited to the mortises of hinges or door jambs as discussed.  
         [0053]     In the depicted embodiment, the flange  308  is attached to the side of the overlay  302  at an angle  312 . In an alternative embodiment, the flange  308  may extend directly from the overlay  302 . In one embodiment, the flange  308  may comprise a knob in the center of the overlay  302  or the like.  
         [0054]      FIG. 4  illustrates a back view of the guard  300  of  FIG. 3 . The back surface  310  may be flat to facilitate a tight fit within the mortise  110 . The edges  304  may further be shaped to correspond to the mortise  110 . In addition, the thickness of the overlay  302  may or may not correspond to the thickness of the leaf  102  or the corresponding element. Adhesive or the like may be applied to the back surface  310  as discussed.  
         [0055]      FIG. 5  illustrates the guard  300  of  FIG. 3  relative to the mortise  110  illustrated in  FIG. 1 . The guard  300  fits within the mortise  110  and may be secured with a fastener through the hole  306  and the hole  114 . The guard  300  fills the mortise  110 , preventing paint from entering the mortise  110 . The edge  304  may provide a defined edge for painting the surface  120 . In addition, the edge  304  may or may not be filleted to accommodate errors in the manufacture of the mortise  110 .  
         [0056]      FIG. 6  illustrates one embodiment of the guard  300  attached to the frame  602  of a door jamb  600 . The frame  602  may comprise a mortise  604 , which may be similar to the mortise  110  illustrated in  FIG. 1  and  FIG. 5 . The guard  300  may be attached to the door frame  602  with a screw  606  or the like through the countersink hole  306 . The flange  308  may be used to stabilize the guard  300 . In one embodiment, when the guard  300  is secured within the mortise  604 , the guard  300  fills in the indentation  112  to create a substantially even surface  608  with the frame  602 , thereby protecting the mortise  604 .  
         [0057]      FIG. 7  illustrates one embodiment of a guard  700  with a protrusion  706 . The guard  700  may include an overlay  702 , a curved edge  704 , a securing device or protrusion  706 , a flange  708 , and a flat back surface  710 . The protrusion  706  may be disposed on the back surface  710  of the overlay  702  and may correspond to the hole  114  of the mortise  110 . The protrusion  706  may be formed integral with the overlay  702  or may be fabricated separately and then attached to the overlay  702 . In one embodiment, the protrusion  706  is made of an elastomer and formed into an elastomeric plug  706 . In another embodiment, the protrusion  706  is made of molded plastic. In a contemplated embodiment, the protrusion  706  has a gripping quality to facilitate securing the overlay  702  within the mortise  110 . The protrusion  706  may eliminate the need for an additional fastener.  
         [0058]      FIG. 8  illustrates a side view  801  and a plan view  803  of the protrusion  706  of  FIG. 7 . The protrusion  706  may be conical and sized to fit within the hole  114 . In a contemplated embodiment, the protrusion  706  secures the overlay  702  within the mortise  110  without damaging the mortise  110  or the hole  114 .
