Stenciling is a process resulting in the application of fixed designs, patterns, or text (collectively, “graphic” or “graphics” or “stenciled graphics”) to a surface. In applying a stencil graphic to a graphic-display surface, a stencil template that comprises a negative-image of the desired final graphic is laid over the graphic-display surface and retained in place. Next, pigment such as paint, marker, or ink is applied to the graphic-display surface through one or more openings in the stencil template, thereby imparting in the selected pigment the desired stenciled graphic to the graphic-display surface.
Two difficulties that arise in stenciling are (i) alignment of stencil templates relative to the graphic-display surface and (ii) reliable temporary affixation of the stencil templates to the graphic-display surface.
Accordingly, a need exists for stenciling apparatus and methods that facilitate precise alignment and reliable temporary affixation of stencil templates to a surface to which a stenciled graphic is to be applied.
Throughout the summary and detailed description, stenciling apparatus and methods of using them are described. Inferential reference to apparatus associated methods constitutes express disclosure of, and antecedent basis for, said apparatus, even if said apparatus is not otherwise expressly disclosed. Similarly, introduction of a physical element in the summary or detailed description includes the corresponding step of providing that element for purposes of supporting a claimed method step reciting that element. Moreover, textual references are made to various pigment-applying implements such as chalk, pencils, pens, daubers, and markers, including paint markers and chalk markers. Such implements are sufficiently ubiquitous and available that they are discussed without corresponding depiction in the accompanying drawings, but are nevertheless regarded as adequately disclosed for purposes of antecedent basis and inclusion in claims.
Various methods of stenciling in accordance with the invention include providing a substrate having a graphic-display surface to which a stenciled graphic is to be applied and at least one stencil template that is magnetically attracted to the substrate. The at least one stencil template defines a graphic negative, and includes openings therethrough corresponding in configuration to, a display graphic to be applied to the graphic-display surface. A basic method proceeds by overlaying the at least one stencil template onto the graphic-display surface for temporary magnetic affixation thereto in a desired location and orientation relative to the substrate. The desired display graphic is imparted to the graphic-display surface by applying a pigment to the graphic-display surface through the openings in the at least one stencil template. The at least one stencil template is then removed from the graphic display surface, leaving behind the applied display graphic(s).
In each of various implementations, the graphic-display surface is bounded by a discernable display-surface periphery. In some embodiments, the display-surface periphery is discernable at the extreme edge of the substrate, while in other embodiments, the substrate is bounded at least in part by a substrate frame they may extend somewhat inwardly of the extreme edge of the substrate to define the display-surface periphery inwardly of the extreme edge of the substrate.
In each of various embodiments, the substrate is a chalkboard for use by hobbyists in crafting, and may include some graphics that are permanent or semi-permanent, and others that are readily erasable and temporary. For instance, a hobbyist might want to stencil his or her family name on the graphic-display surface in a permanent or semi-permanent pigment (e.g., paint marker), while adding seasonal (e.g., holly leaves, wreaths, pumpkins, etc.) details in a more readily removable pigment such as erasable chalk. Another illustrative context in which such a chalkboard may serve as the substrate is in the food service industry. For example, a board with offerings may include some permanent or semi-permanent headings such as “specials,” “beverages,” “sandwiches,” etc., while leaving space for less permanent information related to specifics under those categories (e.g., “turkey with one side and beverage,” prices, etc.).
Various alternative stenciling methods involve aligning and spacing stencil templates relative to the display-surface periphery using at least one provided peripheral guide element. Each peripheral guide element includes mutually-spaced positioning indicia and is configured for selective magnetic affixation along the display-surface periphery. After magnetically affixing the at least one peripheral guide element to the graphic-display surface along the display-surface periphery, a user overlays and magnetically affixes the at least one stencil template onto the graphic-display surface with reference to the positioning indicia of the at least one magnetically affixed peripheral guide element. In a manner that will be more readily appreciated by reading the detailed description, the “reference to positioning indicia” may be either “direct” or “indirect.” Depending on the precise circumstances of method execution—including user discretion—the at least one magnetically affixed peripheral guide element is removed from the graphic-display surface before or after the application of pigment to the graphic-display surface through an at least one opening in a magnetically affixed stencil template.
In accordance with still addition methods, stencil templates are positioned, aligned, and spaced with reference to one or more interior guide elements. Interior guide elements are similar in functionality to peripheral guide elements, but differ in positioning along the graphic-display surface. More specifically, whereas peripheral guide elements are generally positioned and magnetically affixed along and in at least general alignment with the display-surface periphery, interior guide elements either (i) are situated entirely to the interior of the display-surface periphery along the graphic display surface or (ii) extend from the display-surface periphery substantially to the interior thereof. The same physical element could be at different times implemented as either a peripheral or interior guide element. That is, in various embodiments, there is nothing inherent in a guide element that classifies it permanently as either a peripheral or interior guide element; in most cases, it is more a matter of selected placement and functionality for a particular application.
In still further implementations, the use of peripheral and interior guide elements is not mutually exclusive. That is, combinations of peripheral and interior guide elements may be magnetically affixed simultaneously to the graphic-display surface to define alignment axes and alignment grids as references for the placement of magnetic stencil templates. In the execution of some methods, a peripheral guide element may be positioned with reference to the substrate periphery, and the an interior guide element positioned with reference to the peripheral guide element. Stencil templates might then be positioned with reference to the interior guide element and/or the peripheral guide elements.
Representative embodiments are more completely described and depicted in the following detailed description and the accompanying drawings.
The following description of variously configured magnetic stenciling sets and associated methods is demonstrative in nature and is not intended to limit the invention or its application of uses. Accordingly, the various implementations, aspects, versions and embodiments described in the summary and detailed description are in the nature of non-limiting examples falling within the scope of the appended claims and do not serve to define the maximum scope of the claims.
Shown in the included drawings are various views and illustrative versions of magnetic stenciling apparatus. Illustrative methods of use are discussed in conjunction with the descriptions and drawings of various associated apparatus.
As explained in the background and summary, there are two main issues associated with present stenciling apparatus and methods that embodiments of the present invention are configured to address. The first issue relates to alignment and placement of one or more templates on a substrate to which a stenciled graphic is to be applied, while the second issue relates to maintaining the one or more stencil templates in place in a reliable, yet readily removable way. Different embodiments of the present invention address one or both of these issues.
A basic embodiment of magnetic stenciling apparatus 10 is described with general reference to
As shown in
The graphic-display surface 110 is bounded by a display-surface periphery 120 within the interior of which display-surface periphery 120 the graphic-display surface 110 extends in at least two dimensions (e.g., horizontally and vertically). Application to the graphic-display surface 110 of the simple stenciled graphic GS shown in

According to one method described in part with reference to
Shown in
According to one method of using a peripheral guide element 200P, with each peripheral guide element 200P situated appropriately, a template-positioning mark 220 corresponding to each positioning indicium 210 of a selected set of template-positioning indicia 210 along that peripheral guide element 200P is transferred to the graphic-display surface 110. In many applications, such template-positioning marks 220 will be nonpermanent. For instance, where the graphic-display surface 110 is configured for use with chalk, the template-positioning marks 220 may be made with a readily erasable chalk.
Continuing in accordance with this first method, with the desired template-positioning marks 220 applied to the graphic-display surface 110, each peripheral guide element 200P is removed from the graphic-display surface 110. From this point, at least one stencil template 250 is overlaid and magnetically affixed to the graphic-display surface 110 with reference to the at least one template-positioning mark 220. Executed in accordance with the order of steps thus far presented, it will be appreciated that the stencil template 250 is affixed to the graphic-display surface 110 with “indirect” reference to the template-positioning indicia 210 of the at least one magnetically affixed peripheral guide element 200P. This is because, when the at least one stencil template 250 is magnetically affixed, the at least one peripheral guide element 200P has already been removed from the graphic-display surface 110, and the stencil template 250 is affixed relative to the template-positioning marks 220 which were, in turn, made with direct reference to the template-positioning indicia 210 of the at least one magnetically affixed peripheral guide element 200P.
If a stencil template 250 is affixed to the graphic-display surface 110 while a peripheral guide element 200P is still affixed thereto, and positioned relative to the template-positioning indicia 210 of that peripheral guide element 200P without transferring template-positioning marks 220 corresponding to same, that stencil template 250 is regarded as having been overlaid and affixed with “direct” reference to template-positioning indicia 210 of that peripheral guide element 200P. Because stencil templates 250 can be magnetically affixed with either “direct” or “indirect” reference to template-positioning indicia 210 of a peripheral guide element 200P, it is to be understood in considering the claims that, unless express language or context relative to other method steps indicate otherwise, a claim is broad enough to encompass stencil template 250 affixation with either or both of “direct” or “indirect” reference to template-positioning indicia 210.
According to a second, alternative or additional method described with reference to
Referring still to
In any event, in accordance with this second illustrative method, with the interior guide elements 200I placed and temporarily affixed in various selected locations along the graphic-display surface 110, additional template-positioning marks 220 corresponding to the template-positioning indicia 210 of the interior guide elements 200I are transferred to the graphic-display surface 110. These interior template-positioning marks 220 are made with reference to, but to the interior of, the peripheral template-positioning marks 220 made as explained in conjunction with
Referring to
Referring to
With the substrate 100 in a “landscape orientation,” the arcuate interior guide element 200I has been magnetically affixed, centered left-to-right, and “leveled” using interior template-positioning marks 220—as well as the longitudinally extending interior guide element 200I—as positioning references. In addition to stencil templates 250 spelling the word “GRAINS,” there are magnetically affixed over the graphic-display surface 110 a pair of non-alphanumeric stencil templates 250 configured for imparting to the graphic-display surface 110 a corresponding pair of mutually mirror-imaged ornamental swirl designs. As with the arcuate interior guide element 200I, the swirl-design stencil templates 250 have been overlaid and magnetically affixed to the graphic-display surface 110 using as a positioning reference at least one of (i) interior template-positioning marks 220 and (ii) the longitudinally extending interior guide element 220I.
With the selected stencil templates 250 affixed as shown in
At the stage of the illustrative process shown in
Certainly, the invention would find use in a broad array of commercial and industrial applications as well. For instance, restaurants frequently display designs and meal specials on boards to which stenciled images are applied. In any event, in one illustrative implementation, the pigments in question are chalks. “Chalk” is used broadly in the present specification and can include, for example, chalks traditionally used on chalkboards and sidewalks, as well as so-called “chalk markers.”
Regardless of the pigments used, a key to successful execution of various implementations is the relative ease with which the pigments are removable from the graphic-display surface 110. More specifically, in various versions, template-positioning marks 220 are applied using a pigment that is more readily removable than is the pigment applied through the openings 260 in stencil templates 250 to impart stenciled graphic GS. In cases in which chalk products are used, for example, template-positioning marks 220 may be applied with a traditional chalk that lends itself to dry erasure, while stenciled graphic GS may be applied using a chalk marker that requires a more robust effort to remove.
In terms of how they are used, chalk markers are much like other types of markers, but contain a liquid pigment adapted for application to surfaces such as chalkboards, and surfaces painted with chalkboard paint. The applied pigment from chalk markers is generally waterproof and robust enough to resist dry erasure, but removable with certain solvents and cleaners, such ammonia-based surface cleaners and solutions of vinegar. Accordingly, when both template-positioning marks 220 and stenciled designs remain on a graphic-display surface 110, the template-positioning marks 220 can be dry erased without disturbing or degrading the stenciled graphic GS design. The pigments applied for various purposes may be thought of and described in product instructions and conversation in terms of varying degrees of “permanent,” “semi-permanent,” and “temporary” or “non-permanent.”
As briefly described in the summary, various methods may involve the contemporaneous implementation of magnetically affixed peripheral and interior guide elements 200P and 200I. Shown in

In addition to reliable—yet removable—retention in set positions, the magnetic attraction of the guide elements 200I and 200P and stencil templates 250 to the substrate 100 provides further advantages associated with various embodiments. Referring to
