BACKGROUND—FIELD OF INVENTION
Sewing diagonally across a square of material is used frequently in making quilts and other sewing projects. It is used to make half-square triangles, to join binding strips, to make “connecting corners”, and other connections of the fabric. It is commonly used to sew quilts made of squares. In the past, to accurately sew diagonally across a square required marking or creasing the square was needed. This method involves a significant amount of time for one that has many squares to mark and this method can leave residue from the physical marks.
A. Introduction of the Problems Addressed
When marking the diagonal, a sewer or quilter has to be careful that the mark will not permanently discolor the fabric or leave a residue on the fabric. Marks made with chalk, pencils, or wheels are purposefully easy to remove. In fact, sometimes they disappear before the quilter wants them to leaving the quilter having to re-mark the fabric or (worse) estimate where the stitch should be placed. Creasing (pressing) the diagonal eliminates the concern and worry of marks, but the crease is often “difficult to see” and even more “difficult to follow” when actually sewing. Having a crease also means that the fabric is not perfectly flat when being sewn. This may create a greater chance of inaccuracy. In addition, creasing is of “limited use” when making half-square triangles and is of essentially “no use” when quilting.
B. Prior Art
Historically, sewing and quilting aids or guides have been too large. In addition, they were at best marked and delineated with complex lines and indicators for use by the seamstress. Several devices have attempted to improve upon the needs for easy marking or indicating where the seams need to be placed on the quilting fabrics. In use, the prior art devices—complex in nature—were difficult to use and install with a sewing machine and therefore limited in use. The new SEW EASY GUIDE addresses these limitations and provides a solution to the stated problems.
Many sewing machines have a “quilting guide” accessory that can be used to sew parallel lines after marking only the first line. This is well-suited to sewing on a plain (non-pieced) fabric, but the typical “quilting guide” does not work well on a fabric made with quilt squares unless the squares are “exactly and precisely” square. Further, the quilting guide accessory is totally unsuitable for half-square triangles, joining binding strips, and making connecting corners.
Other sewing guides on the market, for example ones that attach to the sewing machine bed, can be helpful in sewing half-square triangles, joining binding strips, and making connecting corners, but only if a quilter is comfortable with guiding the fabric on top of the guidelines. However, these guides are not suitable for quilting because they attach to the sewing machine bed where the guidelines are covered by a quilt or sewing project.
For the many avenues and attempts to solve the needs to accurately and easily mark the quilts or facilitate the sewing, all the known prior art has fallen short of solving the problems.
There are but a few patents for sewing and drawing guides such as taught by the SEW EASY GUIDE. Examples of prior sewing guides or marking indicators begin with U.S. Pat. No. 647,339 issued to Thompson (1900). This teaches an apparatus for mechanical drawings. While possibly helpful to layout design shapes and patterns, the invention does not teach any use directly with a sewing machine or quilting apparatus.
A U.S. Pat. No. 846,006 issued to Bryson (1907) teaches the well-known combination protractor and ruler device. Here, a helpful layout device is taught but no mention of the embodiment or use as described for the SEW EASY GUIDE.
Another example include a U.S. Pat. No. 4,779,346 issued to Schafer (1988) which teaches a transparent, measuring device with markings on its surface. It is a much thicker device ad teaches no use with sewing or quilting machines.
Several devices have been commercialized that involve marking fabric for quilting and sewing. None teach a use with a machine where the guide is visible and on top of the fabric. The other devices known lie under the fabric and contiguous to the machine bed or are simply design layout devices. Examples include transparent rulers and guides from Pam Bono Designs—The Angler and Angler II; Great American Quilt Factory's Possibilities series of tools and devices; Checker Distributors Shape Cut device; Omnigrip rulers available through many dealers and distributors; Quilt Bus rulers; and finally, various Martingale rule and template devices.
None of the prior art teaches all the features and capabilities of the SEW EASY GUIDE device. As far as known, there are no devices at the present time which fully meet this need with as simple and few of components and superior operation as the present SEW EASY GUIDE device. It is believed that this device is made with fewer and less complex parts, of a more simple and durable design, and with much with much easier and improved method of use than any previous sewing guide devices. As far as known, there are no devices at the present time which fully meet the need for a quilting or sewing guide device as well as the SEW EASY GUIDE Device.
SUMMARY OF THE INVENTION
The Diagonal Sewing Guide known as the SEW EASY GUIDE enables one to easily and accurately sew or quilt diagonally across squares without the time-consuming task of marking or creasing the squares. It is comprised of parts including, but not limited to, an essentially rectangular strip of thin, clear and flexible plastic with guide markings, the strip having a top surface, having a needle aperture and a means to attach the guide device to a sewing machine. Since there is no marking involved, there are no worries about marks coming off too soon or staying on where they are not wanted. Since a crease is not necessary for a guideline, the fabric remains flat during sewing, which increases the accuracy of the sewn line.
The Diagonal Sewing Guide, known as the SEW EASY GUIDE, is very easy to use. The device simply attaches to the bottom of the presser foot, without harming the presser foot, and “rides” on top of the fabric. This makes it easier to see where one is sewing. The guide works, when quilting or topstitching, even if the quilter's squares are not perfectly square.
OBJECTS AND ADVANTAGES
There are several objects and advantages of the SEW EASY GUIDE. There currently exist few mechanisms for aiding a seamstress or quilter in the fashion afforded by this invention. Having a simple seam guide that is attached to the sewing machine and that “rides” above the fabric to be sewn is an advancement long-sought after in the sewing and quilting communities. In this regard, it would be advantageous to have an improved guide device that solved these problems. This improvement would increase the ability of a seamstress to use quickly and efficiently sew common shapes in a very repeatable manner. Thus, improving the quality and effectiveness of the user.
Advantages and objects of the present invention is that it is removable, re-usable, flexible, durable, and inexpensive. Further, it is versatile in that it can be used not only as described below, but in a variety of other situations as may occur to the sewing enthusiast.
Other advantages and additional features of the present SEW EASY GUIDE will be more apparent from the accompanying drawings and from the full description of the device. For one skilled in the art of sewing devices and improvements for sewing templates and guides, it is readily understood that the features shown in the examples with this mechanism are readily adapted to other types of sewing guide improvements.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
The present device is a mechanism for a sewing guide called a SEW EASY GUIDE 31.
This mechanism is comprised of an essentially rectangular strip of thin, clear and flexible plastic with markings, the strip having a top surface 32, a length 33 and a width 34, having a needle aperture 41 for a needle to reciprocate therein, and having a means 38 to attach the device 31 to a sewing machine 43.
The improvement over the existing art is providing a device that is removable, re-usable, flexible, durable, inexpensive, and versatile.
There is shown in FIGS. 1–7 a complete operative embodiment of the SEW EASY GUIDE Device 31. In the drawings and illustrations, one notes well that the FIGS. 1–7 demonstrate the general configuration of this invention. The preferred embodiment of the device is comprised of only a few parts as shown in FIG. 1–7 of the drawings.
These parts include, but are not limited to, an essentially rectangular strip of thin, clear and flexible plastic with markings, the strip having a top surface 32, a length 33 and a width 34, having a needle aperture 41 and having a means 38 to attach the device 31 to a sewing machine 43.
Various important features of these components are delineated in FIGS. 2–7 of the drawings and are described below in appropriate detail for one skilled in the art to appreciate their importance and functionality to the SEW EASY GUIDE Device 31.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the SEW EASY GUIDE Device 31 that is preferred. The drawings together with the summary description given above and a detailed description given below serve to explain the principles of the SEW EASY GUIDE Device 31. It is understood, however, that the SEW EASY GUIDE Device 31 is not limited to only the precise arrangements and instrumentalities shown.
As shown in FIG. 1, the SEW EASY GUIDE Device 31 is made of transparent plastic, composite material or equal, approximately 15 mil thick. It is about 1′′ wide 34 by various lengths 33. A centerline 36 in color A (for example, solid black) is centered down the length of the top. A line 37 and 37A in color B (for example, dashed red) is on each side of the solid black center line, parallel to the solid black center line, approximately 1⁄4 inch away. The corners 35 of the front end of the guide may be slightly rounded to prevent the guide 31 from catching on the quilt.
The back end of the guide has a needle aperture 41 (hole) (about 1⁄4 inch diameter) for the sewing machine 43 needle to pass through the guide 31. The guide 31 also has a means 38 such as an adhesive to hold the guide 31 to the bottom of the presser foot 40 flat plane area 42. There is also a removable, re-usable protective cover means 39 such as a tab that protects the means 38 when the guide 31 is not on the presser foot 40.
To use the guide 31, one removes the protective tab 39 from the guide 31. One should save the protective tab 39 to use when storing the guide 31 when it is not on the presser foot 40. Choose a presser foot 40 with a wide base, and place it on the adhesive end of the guide 31 as shown in FIG. 2A, centering solid black line 36 on guide with center of presser foot's needle aperture 41. Make sure needle aperture 41 in foot is on top of hole in guide 31. It may be helpful to turn foot 40 upside down and check that the dashed lines are also centered on the bottom of the presser foot 40. Optional: If one's presser foot 44 has a slot that opens to the side of the foot, one may mark and cut a corresponding slot in the guide 31 if one wishes (remove foot 40 from guide while cutting slot to prevent damage to foot, then re-attach the guide to the foot, aligning the openings).
With guide 31 attached to foot 40, attach foot 40 to sewing machine 43 as shown in FIG. 3, one being careful not to bump guide 43 off of foot or out of alignment. Make sure needle is in center needle position 41, if the user machine has this feature incorporated 38.
With care, the guide 31 will not come off during sewing. The seamstress/quilter must just remember to use care when lifting and lowering presser foot 40 and when turning quilt, because the guide 31 is only secured by the adhesive 38 holding it to the presser foot 42. If desired, extra security can be obtained by wrapping regular invisible tape around the toes of the presser foot flat 42 and the guide 31, however one must remember not to block the needle hole 41.
Shown in FIG. 4 is how to quilt diagonally across squares: One places the quilt under the presser foot 40 and guide 31. Then one positions the needle at the corner of a square (FIG. 4A). One then stitches across the square keeping the solid black center line 36 on the guide centered over the corner of the square opposite the needle (FIG. 4B). When the needle reaches the opposite corner, one should line up the solid black line 36 of the guide 31 with the next corner and continue sewing (FIG. 4C).
FIG. 5 shows how to use “small” fabric squares 45 on top of “large” fabric pieces 46 to make triangles 47 at corners of squares (FIG. 5B) or triangles 47 at corners of rectangles (FIG. 5C). One sews the same as in FIG. 4, except guide the solid black line 36 slightly off the exact corner of the square (FIG. 5A), on the side of the square that will get trimmed away—this allows for “turn of the cloth”.
FIGS. 6A and 6B show two strips 49 being joined with a diagonal seam 52. One sews the same as in FIG. 4 except guide the solid black line 36 slightly off the exact corner of the “square” (FIG. 6A), on the side of the strips 49. That strip will get trimmed away which allows for “turn of the cloth”. FIG. 6C shows an optional method of positioning the strips 49 to be sewn in an edge “alignment”.
FIG. 7 shows how to use the guide 31 to piece half-square triangles 51,51A from squares. One places two same-size squares 50,50A of fabric right sides together. Then one positions one of the side lines 37,37A on the guide 31 on top square's 50,50A opposite corners (the needle will be sewing a scant 1⁄4 inch from the center diagonal of the squares—scant is a measurement term of art meaning, in this context, approximately 1/32 of an inch less than a full 1⁄4 inch measurement). Next one sews across the square, being careful to keep the dashed line 37 on the guide centered over the corner of the square opposite the needle (FIG. 7A). One sews across the square a scant 1⁄4 inch on the other side of the center diagonal 52,52A of the square, again aligning the dashed line on the guide 31 with opposite corners of the top square (FIG. 7B). One now has two diagonal lines of parallel stitching, almost 1⁄2 inch apart. One cuts on the center diagonal 52, 52A of the squares, between the lines (cut area 53) of stitching (FIG. 7C) to yield two half-square units 51, 51A (FIG. 7D).
For one to use the guide 31 to piece half-square triangles using the grid panel system which is a plurality of diagonals 50B, one only needs to draw a grid of squares (no diagonal marking necessary) on the wrong side of ones fabric panel, then one positions the dashed lines and sew as in FIG. 7A. Because one is using a gridded panel, one will sew across many squares before he or she needs to reposition the fabric (FIG. 7E).
The details mentioned here are exemplary and not limiting. Other specific components specific to describing a SEW EASY GUIDE Device 31 may be added as a person having ordinary skill in the field of sewing and quilting guides well appreciates.
OPERATION OF THE PREFERRED EMBODIMENT
Quilters and seamstresses who sew and piece fabric into intricate designs and patterns recognize the need to have an improved manner to efficiently guide the formation of squares and other geometric shapes. This is because to date the help devices have been complexly marked and awkward to use. This is a handicap that leaves many frustrated and disappointed at the time to complete a seemingly simple task of sewing the patterns to larger fabric piece.
The new SEW EASY GUIDE Device 31 addresses the needs and is simple to use. As described above in detail, the guide 31 is attached by means of the adhesive backing 38 directly to the flat plane 42 of the presser foot 40 on a sewing machine 43. Then the fabric pieces 46 and geometric shapes 45 or triangles 47,47A are sewn to the fabric 46. Likewise, strips of cloth 49 may be introduced under the guide 31 and sewn together. These various uses may be summarized for an exemplary purpose and not as a limitation in TABLE A.
