The disclosure relates to saw guides and more particularly pertains to a new saw guide for facilitating cutting perpendicularly to a selected edge of a substrate. The present invention discloses a saw guide comprising a guide plate that can be cut to match the widths of narrow and wide sections base plates of a variety of circular saws.
The prior art does not teach a saw guide comprising a guide plate comprised of first and second sections that have widths complementary to the widths of narrow and wide sections of a base plate of a circular saw to facilitate cutting from left or right handed positions relative to the saw.
An embodiment of the disclosure meets the needs presented above by generally comprising a guide plate, which is rectangular. A first rail is attached to a lower face of the guide plate and extends between a first side and a second side of the guide plate proximate to and parallel with a first edge of the guide plate. The first rail is configured to be abutted to a selected edge of a substrate with the guide plate positioned atop the substrate. A first fence and a second fence are attached to an upper face of the guide plate and extend in parallel between the first edge and a second edge of the guide plate defining a first section, a second section and a medial section of the guide plate. The first section and the second section extend along a first side and a second side of the guide plate, respectively, and have widths equivalent to those of narrow and wide sections of a base plate of a circular saw, respectively. The first section and the second section are configured for selective positioning of the narrow section and the wide section of the base plate, respectively, with an outer edge of the narrow section and an outer limit the wide section abutting the first fence and the second fence, respectively. A user is positioned to actuate the circular saw to selectively cut the substrate perpendicularly to the selected edge.
Another embodiment of the disclosure includes method of customizing a circular saw guiding device. Steps of the method include positioning a narrow section of a base plate of a circular saw upon a first section of a guide plate, abutting an outer edge of the narrow section to a first fence, and passing a blade of the circular saw through the first section for cutting the first section to match a width of the narrow section. Additional steps of the method entail positioning a wide section of the base plate upon a second section of guide plate, abutting an outer limit of the wide section to the second fence, and passing the blade through the second section for cutting the second section to match a width of the wide section.
Yet another embodiment of the disclosure includes method of cutting a substrate perpendicularly to a selected edge. Steps of the method include positioning a guide plate atop a substrate so that a first rail attached to a lower face of the guide plate abuts a selected edge of the substrate, positioning a first edge of the guide plate on the substrate at a desired location for making a cut, positioning a narrow section of a base plate of a circular saw upon a first section of the guide plate, abutting an outer edge of the narrow section to a first fence attached to an upper face of the guide plate, and passing a blade of the circular saw through the substrate for cutting the substrate perpendicularly to the selected edge.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A first fence 28 and a second fence 62 are attached to an upper face 30 of the guide plate 12 and extend in parallel between the first edge 20 and a second edge 32 of the guide plate 12. The first fence 28 is parallel to the first side 18 of the guide plate 12 and defines a first section 34 of the guide plate 12 having a width 38 equivalent to a width 40 of a narrow section 42 of a base plate 44 of a circular saw 46. The second section 36 and the second side 102 of the guide plate 12 define a second section 36 of the guide plate 12 having a width 48 equivalent to a width 50 of wide section 52 of the base plate 44. The first fence 28 and the second fence 62 also define a medial section 104 of the guide plate 12.
The first section 34 and the second section 36 are configured for selective positioning of the narrow section 42 and the wide section 52 of the base plate 44, respectively, with an outer edge 54 of the narrow section 42 and an outer limit 56 of the wide section 52 abutting the first fence 28 and the second fence 62, respectively. A user is positioned to actuate the circular saw 46 to selectively cut the substrate 26 perpendicularly to the selected edge 24.
Circular saw 46 in the context of this specification should be interpreted to mean any handheld motorized saw that is equipped with a base plate 44 through which a blade 58 extends. The circular saw guiding device 10 offers several advantages, as will be apparent to those skilled in the art of saw guides. It can be readily repositioned, thereby enabling the user to make numerous cuts in rapid succession and with a high level of reproducibility. The ready repositioning of the circular saw guiding device 10 also enables rapid switching between left handed cuts and right handed cuts. The medial section 104 and the first section 34 provide ample space for a user to position their hand for stabilizing the guide plate 12 while cutting with the wide section 52 of the base plate 44 of the circular saw 46 positioned on the second section 36 of the guide plate 12. Additionally, the guide plate 12 is positioned between the base plate 44 and the substrate 26, thereby preventing any marring of the substrate 26 as the cuts are made. A hole 60 is positioned in the guide plate 12 and is configured for selective insertion of a hanging element (not shown), such as a hook, nail, or the like, to stow the circular saw guiding device 10 when its use is not required.
As is shown in
As is shown in
The circular saw guiding device 10 also may comprise a second rail 72, which is attached to the lower face 16 of the guide plate 12 and which extends between the first side 18 and the second side 102 of the guide plate 12 proximate to and parallel with the second edge 32. The second rail 72, like the first rail 14, is configured to be abutted to a selected edge 24 of a substrate 26 with the guide plate 12 positioned atop the substrate 26. The second rail 72 provides flexibility to the user when cutting substrates 26 that will fit between the first rail 14 and the second rail 72 in that the user can cut the substrate 26 from either side. The user also can rotate the guide plate 12 180° to position the second section 36 of the guide plate 12 to receive the wide section 52 of the base plate 44, which is a preferred approach to making cuts.
Each brace 74 of a plurality of braces 74 is attached to and extends between the second rail 72 and the guide plate 12, as is shown in
In one configuration, the guide plate 12, the first fence 28, the second fence 62, and the first rail 14 comprise plastic, wood, or the like, and are configured to be cut by the blade 58 of the circular saw 46. Also in this configuration, the first section 34 and the second section 36 of the guide plate 12 are dimensionally wider than the narrow section 42 and the wide section 52 of a base plate 44, respectively. Thus configured, the circular saw guiding device 10 is readily customizable to a variety of circular saws 46 wherein the narrow section 42 and the wide section 52 of a base plate 44 have a variety of widths (40 and 50, respectively). The first section 34 is configured to have positioned upon it the narrow section 42 of the base plate 44, with the outer edge 54 of the narrow section 42 abutting the first fence 28. The user then is positioned to pass the blade 58 of the circular saw 46 through the first section 34 to cut the first section 34 to match the width 40 of the narrow section 42. Similarly, the second section 36 is configured to have positioned upon it the wide section 52 of the base plate 44, with the outer limit 56 of the wide section 52 abutting the second fence 62. The user then is positioned to pass the blade 58 of the circular saw 46 through the second section 36 to cut the second section 36 to match the width 50 of the wide section 52.
The present invention anticipates a method of customizing a circular saw guiding device 76. A first step 78 of the customization method 76 is positioning a narrow section 42 of a base plate 44 of a circular saw 46 upon a first section 34 of a guide plate 12, as is shown in
A fourth step 84 of the customization method 76 is positioning a wide section 52 of the base plate 44 upon a second section 36 of guide plate 12, as is shown in
In use, the circular saw guiding device 10 enables a method of cutting a substrate perpendicularly to a selected edge 90. The cutting method 88 comprises a first step 92 of positioning a guide plate 12 atop a substrate 26 such that a first rail 14 that is attached to a lower face 16 of the guide plate 12 abuts the selected edge 24 of the substrate 26. A second step 94 of the cutting method 88 is positioning a first side 18 of the guide plate 12 on the substrate 26 at a desired location for making a cut. A third step 96 of the cutting method 88 is positioning a narrow section 42 of a base plate 44 of a circular saw 46 upon a first section 34 of the guide plate 12. A fourth step 98 of the cutting method 88 is abutting an outer edge 54 of the narrow section 42 to a first fence 28 that is attached to an upper face 30 of the guide plate 12. A fifth step 100 of the cutting method 88 is passing a blade 58 of the circular saw 46 through the substrate 26 to cut the substrate 26 perpendicularly to the selected edge 24.
Alternatively, depending on positioning of the substrate 26 and access to the selected edge 24, the cutting method 88 may entail positioning a second side 102 of the guide plate 12 on the substrate 26 at a desired location for making a cut, positioning of a wide section 52 of the base plate 44 upon a second section 36 of the guide plate 12, and abutting an outer limit 56 of the wide section 52 to the second fence 62.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
