Description




FIELD OF THE INVENTION




The present invention relates to a shielding apparatus, particularly shields used for painting and, more particularly, to a corner paint shield for glass pane windows, doors, baseboards, ceilings, etc.




BACKGROUND OF THE INVENTION




Apparatus for shielding liquids, particularly paints and stains from an undesired area are known in the art. Such shields have taken the form of rolled adhesive tape and handheld devices with flexible or semi-rigid blades. The tape or blade is placed over the area that is not to receive the liquid, for exemplary purposes, paint. Once the shield is placed over the area to be protected, a paintbrush or roller may apply paint to the limits of the desired area in a not-so-careful manner such that if that the brush or roller goes beyond the desired location, excess paint will be applied to the shield and not the undesired surface.




A common application of paint in a highly visible area is on wood trim moldings around doors and windows. Accuracy on the application of paint around windows is required due to the undesirability of paint on the window screen or other window treatment. Of particular difficulty is in a corner where moldings form a 90° or other angle. When using a brush to apply paint, the corner tends to bunch up the bristles and an excessive amount of paint is unintentionally squeezed from the brush thereby depositing an overabundance of paint in the area. This condition results in the excess paint flowing to undesired areas necessitating difficult removal of the excess.




Straight, single blade shields are often ineffective as a device as they only protect one molding forming one half of the corner angle. Use of two, single blade shields is awkward to hold in position and control as described in Canadian Patent No. 2,176,402 to Spence. Such single blade devices also suffered from a lack of structural stability, difficulty in handling and deficiencies in collecting and holding excess paint.




The prior art shields described above are problematic due to the use of designs and materials which lack strength, stability, adequate rigidity and are difficult to use.




Prior art designs are also problematic due to the inability or deficiency to collect and hold excess paint or liquid deep in the corner or angle between adjoining moldings. The paint shield disclosed in Spence includes grooves that do not extend into and through the corner allowing for excess paint to deposit and uncontrollably flow to undesired areas as described above.




Prior art shields are also problematic through use of continuous and relatively large bottom contact surfaces that cover the area to be protected. This is disadvantageous in several respects. A large contact surface area on the shield increases the probability the contact surface will be nonplanar and the shield will be skewed and thus will not lie flat and closely conform to the surface to be protected. Similarly, a large shield contact surface is also more prone to contact imperfections or obstructions in the surface to be protected which will force the shield away from the area to be covered. Additionally, and possibly most important, a large shield contact surface will distribute the force applied on the shield to the protective area thereby reducing the pressure from the critical area of the shield which is immediately adjacent and abuts the extreme edge of the surface to be painted.




These deficiencies permit, or increase the probability, that excess paint will pass by the shield to the area to be protected such as window glass.




Therefore, it would be desirable to provide a paint shield that improves upon or overcomes the problematic conditions in the prior art. It would also be desirable to provide a paint shield that is simple, inexpensive, easy and comfortable to use as well as being reusable an indefinite amount of times.




SUMMARY OF THE INVENTION




The present invention is a paint shield advantageously usable on a window, for example and more advantageously, in a corner of a window to protect the window glass from excess paint from a paint brush applying paint to a surrounding window trim molding.




The present invention includes at least one arm with a member attached thereto for manipulating the arm. The arm includes a top surface having at least one groove and an outer lip formed from the top surface and a bottom surface having a recess. The outer lip abuts the surface to be painted and prevents paint from seeping to the surface to be shielded from paint.




The arm of the present invention may terminate in a raised side wall at each end of the arm. The groove on a top surface of the arm extends substantially the entire length of the arm ending at the raised side walls or immediately adjacent thereto.




The outer lip may include an outer wall joining the top and bottom surfaces of the arm and may further include an outer edge formed by the outer wall and the bottom surface of the arm.




In a preferred aspect of the present invention, the paint shield includes first and second interconnected arms disposed at a 90° angle having a member extending between the first and second arms for manipulating the position of the paint shield.

DETAILED DESCRIPTION OF THE INVENTION




As shown in

FIGS. 1-4

, the paint shield


10


is preferably in the form of a one piece, unitary, molded member. The paint shield


10


is preferably formed of a molded plastic; although other materials, such as wood, composites, metal, etc., may also be employed. Further, the paint shield


10


is preferably formed with a substantially rigid construction to prevent flexing in use.




As shown in

FIGS. 1 and 2

, by example only, the paint shield


10


includes first and second arms


12


and


14


, respectively. Preferably, the arms


12


and


14


are disposed 90° apart and interconnected at a common edge or joint


16


along a 45° angle. It will be understood that the paint shield of the present invention may also take other forms including one or more arms, such as a simple straight edge with one arm, or a square or other polygonal shape with a plurality of arms.




The first arm


12


and second arm


14


are similarly constructed. Thus, the following description of the construction of the second arm


14


will be understood to apply equally to the construction of the first arm


12


.




As shown in

FIG. 4

, the second arm


14


has a generally wedge or triangular shape extending between a higher or longer height inner wall


18


to a short, angled outer wall


20


. Outer wall


20


ends at an outer edge


21


.




At least one, and preferably, a plurality of recessed grooves, with three recessed grooves


22


,


24


and


26


being illustrated by way of example, are formed in the top surface


29


of the second arm


14


. The recessed grooves


22


,


24


and


26


may take the form of many different cross sections, such as polygonal, circular, etc. Each of the grooves


22


,


24


and


26


project downwardly from the top surface


29


of the second arm


14


for a predetermined distance or depth. It is understood the number of recessed grooves, cross section configuration, and depth may vary to accommodate the particular liquid or application.




Flat top surface strips


23


,


25


,


27


and


28


are formed adjacent to each of the grooves


22


,


24


and


26


. Due to the preferred wedge or triangular shape of the arm


14


, the top surface strips


25


,


27


and


28


lie in a substantially common plane or along a common arc; but have a generally downwardly angled or sloped configuration from the top edge of the inner wall


18


to the top edge of outer wall


20


.




As shown in

FIG. 4

, by example, outer wall


20


is angled or sloped with respect to top surface


29


and ends in an outer edge


21


. It is understood that outer wall


20


may vary in height between the outer edge


21


and the top edge of outer wall


20


adjacent top surface strip


28


to accommodate different profiles and surfaces of trim moldings


32


. Likewise, and for similar reasons, outer wall


20


may be vertical, angled or contoured to accommodate trim moldings


32


.




As best seen in

FIGS. 1 and 3

, the recessed grooves


22


,


24


and


26


extend substantially the entire length of second arm


14


. Preferably, arm


14


includes a raised sidewall


30


which is located on and covers the end of arm


14


. The grooves


22


,


24


and


26


extend from side wall


30


to the edge or joint


16


between the first arm


12


and second arm


14


. In this manner, the recessed grooves


22


,


24


and


26


on both of the first and second arms


12


and


14


, respectively, are disposed in open communication with each other at the 90° angle or joint


16


. As shown in

FIGS. 1 through 3

, the recessed grooves


22


,


24


and


26


end at another raised sidewall


30


on the first arm


12


. The raised sidewalls


30


prevent excess paint from flowing from the grooves to the trim molding


32


or surrounding window


33


. It is further understood that where paint shield


10


includes one arm, each end of the arm will preferably include a raised sidewall


30


. In an alternate aspect of the invention, the recessed grooves end or are closed immediately adjacent the end of first arm


12


and second arm


14


obviating the primary need for raised sidewalls


30


.




The recessed grooves


22


,


24


and


26


function to collect excess paint from a paintbrush or roller as the paintbrush or roller is moved along the conventional trim molding


32


, shown in

FIG. 2

, surrounding a window


33


. The collected paint can be easily washed out or otherwise removed from the grooves


22


,


24


and


26


for reuse of the paint shield


10


. At the same time, the top surface strips


23


,


25


,


27


and


28


in conjunction with the recessed grooves


22


,


24


and


26


, form a solid, continuous surface overlaying the glass window


33


which prevents any paint from the paintbrush or roller from contacting the glass.




Although disclosed and shown for use in a window or window corner, it is understood that paint shield


10


is equally functionable for shielding paint or other materials from doors, ceilings, floors, baseboards, walls, trim moldings and the like.




As shown in

FIG. 4

, a recess


34


is formed in the bottom surface of the first arm


12


and second arm


14


and extends substantially along the entire length of the first arm


12


and second arm


14


. The recess


34


extends laterally across the width of each of the first and second arms


12


and


14


respectively. The recess


34


forms a lip


40


which includes the outer wall


20


, outer edge


21


and an outer bottom surface


38


. Preferably outer edge


21


lies in the same plane as outer bottom surface


38


. Recess


34


, by example, is generally rectangular in shape and includes an angled portion


35


which is adjacent the outer bottom surface


38


of lip


40


. Angled portion


35


is generally parallel to the top surface strip


28


to maintain adequate material thickness for strength and rigidity. It is understood that both recess


34


and angled portion


35


may be of any size and shape to accommodate the environment or application of paint shield


10


or to improve the function and ease of use of paint shield


10


.




The configuration of lip


40


prevents, or reduces the possibility of, paint seeping past outer wall


20


, outer edge


21


and under the outer bottom surface


38


to the glass


33


. Outer bottom surface


38


is relatively narrow in a lateral direction and extends the entire length of first arm


12


and second arm


14


. This relatively small contact surface area or footprint effectively concentrates the weight of paint shield


10


and/or the force applied by the user on the shield to the glass window


33


thereby further reducing the possibility of paint passing by outer edge


21


and outer bottom surface


38


.




Recess


34


also forms an inner bottom surface


36


. Inner bottom surface


36


and outer bottom surface


38


are substantially in the same plane although it is understood the surfaces may be in different planes to accommodate a step or contour in the window


33


or molding


32


which shield


10


rests on and/or abuts.




As shown in

FIGS. 1 and 2

, in a preferred aspect, a manipulating means or member


46


extends between the first arm


12


and second arm


14


. By example, the member


46


preferably has a general hollow configuration with a recess


47


extending upward from a bottom surface


50


contiguous with the inner bottom surface


36


. In this aspect, the member


46


bottom surface


50


lies in the same plane as the arm inner bottom surface


36


and arm outer bottom surface


38


permitting the paint shield


10


and accompanying member


46


to lie flat or flush against the window


33


. In an alternative aspect, the member bottom surface


50


may lie in a different plane from the arm bottom surfaces


36


and


38


to allow clearance, or interference as desired, of the member


46


with the window


33


or other details or obstructions.




Preferably, member


46


is integrally molded to first arm


12


and second arm


14


. However, it is understood member


46


may be attached using conventional attachments such as mechanical fasteners or adhesive. In an alternative aspect, where the paint shield


10


includes only one arm, the member


46


is attached to the arm in a similar manner as described above.




In a preferred aspect, projection or handle


48


is attached on an upper surface


52


of member


46


to facilitate handling and movement of the paint shield


10


. Preferably, handle


48


is integrally molded with member


46


and is generally hollow and rectangular in form extending unitarily upward from a top surface


52


of the member


46


. Although handle


48


is shown as a generally rectangular-shaped projection, handle


48


may take any shape or form suitable for easily manipulating or moving the shield


10


such as a knob, a post, or if member


46


is positioned away from glass


33


, a through hole. Member


46


may itself be configured to act as a handle without a separate handle


48


formation.




Referring to

FIG. 2

, in preferable operation, the paint shield


10


is positioned using member


46


and handle


48


in a window


33


surrounded by a conventional trim molding or frame


32


. The paint shield


10


is placed against the window glass pane


33


and is slid along the glass toward the desired position along the trim molding


32


. As shown in

FIG. 2

, the preferred paint shield


10


includes two arms positioned 90° apart for use in a 90° corner.




The paint shield


10


is forced into the 90° corner of trim molding


32


such that outer wall


20


or, depending on the shape of the molding


32


, outer edge


21


is in abutting engagement with the outer surface of trim molding


32


(not shown). Pressure is maintained to position the paint shield


10


against the outer edge of trim molding


32


such that, as appropriate, outer wall


20


or outer edge


21


abuttingly engages the outer wall of trim molding


32


. Simultaneously, outer bottom surface


38


and inner bottom surface


36


abuttingly engages the glass pane of window


33


.




The operator then applies the paint to the desired location on trim molding


32


. In the event paint is applied beyond the outer edge of trim molding


32


, excess paint is collected and stored in recessed grooves


22


,


24


and


26


preventing excess paint from flowing onto window


33


. Recessed grooves


22


,


24


and


26


are continuous and therefore collect and store paint along the entire length of first and second arms


12


and


14


respectively.




As outer wall


20


, or outer edge


21


, abuttingly engages the outer surface of trim molding


32


, a minimal amount of paint, if any, will flow down outer wall


20


to outer edge


21


. Preferably, outer edge


21


, lies in the same plane as outer bottom surface


38


and thereby abuttingly engages the window


33


glass pane, preventing paint from passing to outer bottom surface


38


. Outer bottom surface


38


abuttingly engages window


33


preventing paint from seeping under outer bottom surface


38


onto additional portions of window


33


.




Upon completion of painting the corner of trim molding


32


, paint shield


10


is removed from window


33


and molding


32


through use of member


46


and handle


48


. Any excess paint that has been applied to the arm top surface


29


and collected in recessed grooves


22


,


24


and


26


, are easily removed through use of an appropriate cleaner for that paint or other liquid. The shield


10


is then ready for reuse.
