- Referring now to
FIG. 1 there is a perspective view of adrawing board 10 according to an aspect of the present invention with portions shown in cut-away view.FIG. 2 is an exploded perspective view of thedrawing board 10 ofFIG. 1 . Thedrawing board 10 includes adrawing substrate 12, asupport housing 14 and aheating element 16. Referring additionally toFIG. 3 , there is depicted thedrawing board 10 as illustrated with a user 38 (as represented by a right hand of the user), adrawing sheet 40 and drawingmedia 42. The drawingboard 10 is for use with the drawingmedia 42 and thedrawing sheet 40. The drawingmedia 42 characterized as becoming softer upon being heated above an ambient temperature. - The
board substrate 12 has adrawing surface 20 and an opposingbacking surface 22. The drawingsurface 20 defines afirst region 26 and asecond region 28. Each of the first andsecond regions drawing sheet 20. Theheating element 16 is disposed adjacent thefirst region 26 with thebacking surface 22 facing theheating element 16. Theheating element 16 and thefirst region 26 are sized and configured to heat thefirst region 26 above the ambient temperature. Thesupport housing 14 is configured to support the drawingsurface 20 and theheating element 16. - It is contemplated that the
first region 26 is heated by theheating element 16. This allows for the first andsecond regions particular drawing media 42 being utilized. Theheating element 16 and thefirst region 26 are preferably sized and configured to heat thefirst region 26 to at least 120 degrees F. Advantageously, this allows for the opportunity to employ a variety of art techniques with the same media. For example, this would allow for both drawing and painting techniques upon a single surface and with a single media. - As is illustrated in
FIG. 3 , theuser 38 may direct the drawingmedia 42 upon thedrawing sheet 40 with thedrawing sheet 40 positioned over thesecond region 28.FIG. 4 illustrates thedrawing sheet 40 being translated across the drawingsurface 20 from thesecond region 28 to thefirst region 26. With thedrawing sheet 40 at thefirst region 26, thedrawing sheet 40 and in turn the drawingmedia 42 may be heated. Because theheating element 16 and thefirst region 26 are sized and configured to heat thefirst region 26 above the ambient temperature, the drawingmedia 42 becomes softer upon theuser 38 pressing the drawingmedia 42 against thedrawing sheet 40 which in turn is pressed against thefirst region 26. This causes the drawingmedia 42 to soften or even melt which is contemplated to produce a different artistic effect and allow for a variety of artistic techniques to be employed by theuser 38. As can be appreciated, the drawingboard 10 allows theuser 38 to move thedrawing sheet 40 back and forth between the first andsecond regions media 42 may be applied in a softened or melted form over thefirst region 26 and then thedrawing sheet 40 may be moved to thesecond region 28 to allow the drawingmedia 42 to cool and harden. In addition, the ability to move back and forth allows theuser 38 to rework and re-blend the drawing media that has been already applied to thedrawing sheet 40. Thefirst region 26 may be used for mixing pigments, blending and quickly covering large areas of thedrawing sheet 40. Thesecond region 28 may be used for initial drawing, for layering colors, for fine details and finishing touches for example. - In another embodiment, the
first region 26 defining a first footprint, and thesecond region 28 includes a portion sized to at least encompass an entirety of the first footprint. This may be irrespective of the size of the particular drawing sheet utilized. As used herein the term footprint refers to the two dimensional contiguous shape as defined by a periphery and the entire area within the periphery. A portion sized to at least encompass an entirety of the first footprint would include an embodiment where the first footprint exactly encompasses. Thus, thefirst region 26 may have a same shape and size as thesecond region 28 and this would result in thefirst region 26 having a portion that at least encompasses an entirety of the first footprint. - The drawing
media 42 may be formed of a variety of materials provided such materials have a characteristic of becoming softer upon being heated above an ambient temperature. In addition the drawingmedia 42 may be of a nature such that it has a media melting point. Suitable materials may include oil, wax or polymer based materials. Such materials may include binders of various types. The drawingmedia 42 may be natural or synthetic in nature. The drawingmedia 42 may take various forms such as a stick or a pencil for example. The drawingmedia 42 may have various pigments, thicknesses and textures. In addition, it is contemplated that thedrawing sheet 40 may be formed of various materials, such as paper, cardboards, boards, panels (such as wooden panels), composite or laminate materials, and other materials utilized by artists with the application of the drawingmedia 42. Thedrawing sheet 42 may be of a natural or synthetic nature. It is contemplated that for relatively thick materials, it may be necessary for thedrawing surface 20 to be heated to a relatively higher temperature to achieve the desired softening effects of the drawingmedia 42 in comparison to a thin sheet of material. - The
board substrate 12 may be formed of various materials. In the embodiment ofFIGS. 1-4 , theboard substrate 12 is formed of a glass material. For example, the glass material may be a tempered glass material. Such a material may be considered suitable for purposes of drawing with various media due to the particular combination of structural strength, rigidity and heat transfer properties. Other materials may be utilized such as various types of plastic, such as a glass filled plastic, or even various types of metal. - In the embodiment illustrated the
board substrate 12 is translucent. However, theboard substrate 12 may be opaque, or partially opaque and partial translucent. In addition, theboard substrate 12 may be colored. In this regard, theboard substrate 12 may be uniformly colored or non-uniformly colored. For example and first andsecond regions - The
board substrate 12 may have various surface characteristics. The drawingsurface 20 and thebacking surface 22 may be the same surface characteristics or differing surface characteristics. For example, the drawingsurface 20 may be formed to be relatively smooth and thebacking surface 22 may be textured with as with frosted glass surface. It is recognized that such surface characteristics may impact the overall transparency or opacity of theboard substrate 12. In addition it is contemplated that the first andsecond regions - The
board substrate 12 may be formed of a single continuous piece of material with regard to thedrawing surface 20. In another arrangement theboard substrate 12 at the first andsecond regions second regions board substrate 12 at the first andsecond regions media 42 upon thedrawing sheet 40. In addition, theboard substrate 12 may have various cross sectional characteristics such as a solid cross-sectional composition or a laminated material. - As mentioned above, each of the first and
second regions drawing sheet 40. Thedrawing sheet 40 may be positioned over thefirst region 26 where it may be heated such as illustrated inFIG. 4 . This allows for heating of theentire drawing sheet 40. Similarly thedrawing sheet 40 may be positioned over thesecond region 28 where it is not exposed to an elevated temperature as in comparison to thefirst region 26 such as illustrated inFIG. 3 . As used herein the term substantially refers to a majority of a given surface area. Thus, it is understood that thedrawing sheet 40 may be overlaid upon thefirst region 26 and at least a majority of the surface area of thedrawing sheet 40 would be overlapped. Similarly, thedrawing sheet 40 may be overlaid upon a portion of thesecond region 28 and at least a majority of the surface area of thedrawing sheet 40 would be overlapped with the second region. In contrast for example, a heated drawing board where substantially all of the board is heated with just a periphery of the board not being heated would not satisfy the limitation of “the first and second regions being sized to substantially overlap with an entirety of the drawing sheet.” This is because while the periphery of the board may not be heated and may be relatively large so as to encompass the subject drawing sheet, it would not overlap with an entirety of the drawing sheet because the heated portion is in the middle of the board. Thus, in this example there would be no analogous structure of a “second region” as an overlapping portion of the periphery is not substantial in comparison to a drawing sheet. - In the embodiment illustrated, the
first region 26 is generally rectangular and smaller than thesecond region 28. Thesecond region 28 is polygon shaped that generally takes the form of a D-shape wrapping about thefirst region 26. It is contemplated that the first andsecond regions first region 26 defines a surface area that is at least a quarter of the surface area of thesecond region 28. It is contemplated that the particular embodiment as illustrated inFIGS. 1-4 is “friendly” to theuser 38 who may be either left or right handed. In this regard, theuser 38 may orient thedrawing board 10 as shown for a right-handed user 38 or rotate the drawing board 180 degrees for a left-handed user 38. This user friendliness is facilitated by the general positioning of thefirst region 26 which is centered with regard to a longitudinal axis of thedrawing board 10 and theelectrical conduit 18 extends out an end of thedrawing board 10. - The
board substrate 12 includes aperipheral edge 24. As mentioned above, thesupport housing 14 is configured to support the drawingsurface 20. In this regards, thesupport housing 14 may support theboard substrate 12 at theperipheral edge 24. In the embodiment illustrated thesupport housing 14 includes aflange 34 that extends inwardly. Theboard substrate 12 may be sized and configured to rest upon theflange 34. Moreover, theboard substrate 12 may be attached to thesupport housing 14 by attachment to theflange 34 such as through the use of an adhesive. Other means for attachment of theboard substrate 12 to thesupport housing 14 are contemplated. For example, a plurality of clips, which may be integrated with thesupport housing 14, may be provided to retain theboard substrate 12 in place. - It is contemplated that it is desirable to maintain the
drawing surface 20 above the level of thesupport housing 14. In this regard, theuser 38 may smoothly translate thedrawing sheet 40 across the drawing surface without any interference of thesupport housing 14 when a portion of thedrawing sheet 40 extends laterally beyond the drawingsurface 20. In addition, in this embodiment, theboard substrate 12 and thesupport housing 14 are formed of different materials. However, it is contemplated that theboard substrate 12 and thesupport housing 14 may be integrally formed with theboard substrate 12 and thesupport housing 14 being a single continuous piece of material. - The
support housing 14 may be formed of various materials. For example, thesupport housing 14 may be formed of a plastic material, such as an injection molded plastic. In the embodiment illustrated thesupport housing 14 includes asupport base 30 with a plurality offeet 36. Thesupport base 30 may be utilized for overall structural stability as well as a means to form an enclosure with theheating element 16 enclosed between thesupport base 30 and theboard substrate 12. Moreover, thesupport base 30 may be used as a support structure for theheating element 16 as well. Thesupport base 30 may include a plurality of vent holes 32 formed through thesupport base 30. The vent holes 32 may be used to ventilate the enclosed space between thesupport base 30 and theboard substrate 12. Such venting is contemplated to remove excess heat from within the enclosed space. This would allow for a more controlled heating of theboard substrate 12. - Though not depicted, it is contemplated that the
support housing 14 may house a light source. To the extent that theboard substrate 12 is translucent, the drawingsurface 20 may be backlit. In addition, thought not depicted, thesupport housing 14 may be configured to store items such as the drawingmedia 42. Such as storage arrangement would however provide for the segregation of any stored elements and theheating element 16. - The
heating element 16 may be an electrical device. Theheating element 16 may be provided with anelectrical conduit 18. However, it is contemplated that the heating element may be battery powered. In the embodiment illustrated, theheating element 16 is a flexible electrical circuit (also referred to as a “flex circuit”). These devices typically include a patterned array of copper traces that may become heated upon the application of an electrical current. Theheating element 16 may be controlled to radiate a variety of temperatures. As such theheating element 16 may include atemperature control 48. Thus, depending upon theparticular drawing media 42 utilized, theheating element 16 may be set at an appropriate temperature in relation to the particular degree of media softening or media melting point. It is contemplated that such a flexible electrical circuit is relatively thin and facilitates an ease of installation. In this regard, as mentioned above, thesupport housing 14 is configured to support theheating element 16. Theheating element 16 may be adhesively attached to thebacking surface 22. As such theheating element 16 is supported by thesupport housing 14 via theboard substrate 12 that is attached to thesupport housing 14. - Referring now to
FIG. 5 , there is depicted another embodiment. Similar reference numerals as those in relation to the embodiments shown inFIGS. 1-4 are used to indicate similarly configured components, however, with those differences as noted below. In this embodiment thedrawing board 10 includes aboard substrate 44. Theboard substrate 44 includesindicia 46 that generally define a periphery of thefirst region 26. As is illustrated, in this embodiment theindicia 46 take the form of a dashed line. In this embodiment, the dashed line is formed upon thedrawing surface 20. In this regard, theboard substrate 44 is formed of an opaque material. However, it is contemplated that where theboard substrate 44 is formed of a translucent material, theindicia 46 may be disposed upon thebacking surface 22. Theindicia 46 are utilized as a visual indicator to theuser 38 of the boundaries of thefirst region 26. Theindicia 46 may be formed by various means. For example, theindicia 46 may be formed utilizing paint. Alternatively the indicia may be formed using a surface treatment, such as an etching, upon thedrawing surface 20. Theindicia 46 need not be restrained to just the periphery of thefirst region 26. For example, the indicia may extend across the entirefirst region 26. - The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show any more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.
