Definitions

  • a tool for measuring and marking fabric includes a sheet of rigid transparent material having opposing first and second planar sides, and a sheet of flexible, transparent material removable adhered to one of the first and second sides to provide a removable non-slip surface.
  • the sheet of flexible material entirely covers one of the first and second sides of the rigid sheet of material and is formed of a vinyl with plasticizers that adheres through surface tension. Lines for measuring and marking are formed on one of either the first and second planar sides of the rigid sheet or on the sheet of flexible material.
  • the present invention avoids the disadvantages of prior methods and achieves a removable non-slip surface that is easily applied and removed, is easily cut to size, is totally transparent, can be interchanged between rulers, will adhere when pressure is applied, does not snag fabric or materials when manipulating the ruler, prevents markings between the ruler and the flexible sheet from rubbing off, can be marked on for a visual aid on the underside of the ruler, resists rolling back from the edge, can be used to create an inking edge, can be taped with clear tape for more permanent adhesion, can be printed on prior to applying to blank plastic, does not damage or alter the ruler, can be used with any flat ruler or template, and is inexpensive, easy to use, and easily understandable.
  • Figure 3 is a top plan view of the first image to be applied to the sheet of transparent material in accordance with the present invention
  • Figure 4 is a top plan view of the second image to be applied to the sheet of transparent material in accordance with the present invention
  • Figure 10 is a top plan view of the composite image formed in accordance with the alternative embodiment of Figures 7 and 8.
  • Figure 12 is a side plan view of a method of forming the tool in accordance with another embodiment of the invention.
  • a pattern of composite lines is formed on the front surface 12 of the rigid sheet 11, the pattern including a plurality of vertical lines 16 running across the width of the sheet and a plurality of horizontal lines 18 running across the length of the sheet.
  • the vertical lines 16 and the horizontal lines 18 are positioned substantially at right angles with respect to one another to thereby create a grid pattern formed of squares 20.
  • selected horizontal and vertical lines are composite lines formed of a first line 24 and a second line 26.
  • the first line 24 is of a first color (or hue) and the second line 26 is of a second color (or hue) that is different from the first color.
  • the first line 24 is superimposed upon the second line 26, and the first line 24 is of a lesser breadth than that of the second line 26, such that the second line 26 is visible on each side of the first line 24 when viewed from the front surface 12.
  • the first line 24 and the second line 26 may also be placed in adjacent or partially overlapping relationship, so long as the two different colors are visible from the front surface 12.
  • the first and second colors are of a contrasting nature, such as yellow and dark green, white and black, dark orange and light blue, black and yellow, or other combinations such that either one of the colors will be visible against backgrounds of various colors or against a multicolored background.
  • a first image 30 consisting of a pattern of horizontal and vertical graduations 32 with short subdivisions 48 extending therefrom at substantially right angles.
  • Each graduation 32 and subdivision 48 is formed from a pair of lines 34 and 36 that outline an uncolored gap 38.
  • the uncolored gaps 38 are bounded on substantially all sides by the pair of lines 34 and 36, and they are disposed centrally therein.
  • the longitudinal ends 39 and 41 of the gaps 38 are not bounded, and there may be applications where there are segments that are unbounded along the length of the composite lines. There may also be applications where it is preferred that the gaps 38 not be centered between the pair of lines 34 and 36. Hence, variations are contemplated in the present invention.
  • each of the lines 57 and 58 has corresponding numbers 62 along the outside rows and columns of squares 56. In the embodiment depicted herein, these numbers 62 correspond to inches, although other units of measurement may be used, such as metric units.
  • the Omnigrid trademark 64 and other legends and indicia 66 appear inside the squares 56.
  • the lines 57 and 58 have a width that is 2 one-thousandths of an inch wider than the width of the uncolored gap 38 formed by the graduations 32. In other words, if the uncolored gap 38 is 12 one-thousandths of an inch wide, the lines 57 and 58 would be 14 one-thousandths of an inch wide.
  • the numbers 62 are preferably 2 one-thousandths of an inch larger than the corresponding uncolored numbers spaces 42 formed in the circles 40 on the first image 30.
  • the intersection of the horizontal and vertical lines 57 and 58 is left blank to provide an unobstructed viewing space that enables a user to precisely align the measuring device.
  • first and second images 30 and 52 When the first and second images 30 and 52 are combined, they form a composite image, as will be described more fully below in conjunction with Figure 10. Briefly, the first image 30 is applied to the back surface of a transparent sheet, and the second image 52 is aligned and applied on top of the first image 30. When the images 30 and 52 are so combined, the contrasting colored second image 52 fills in the gaps 38 and number spaces 42 on the first image 30, creating a composite set of lines.
  • the preferred method is the screen printing process because it permits the application of a heavy deposit of ink.
  • the images described above are first created and then transferred to a screen.
  • the screen is a commercially-available material that has a thread count in the range of 150 to 400 threads per inch.
  • present methods do permit the direct transfer of an electronic or computer image to a print screen, bypassing the step of using an ortho film, although this is much more expensive.
  • a lithograph press, an engraving process, thermal (hot) stamping of foil, or a photographic process may also be used, as well as any combination of graphics and manufacturing.
  • high-speed laser printers that print the computerized image directly to a plastic sheet are also available. Virtually any pigment transfer method may be used to generate the images of the present invention on the transparent sheet. Another method takes advantage of precision cutting equipment to cut out pre-printed adhesive plastic that can be applied as a layered substrate to the transparent sheet.
  • the screen is formed for the first image 30, it is mounted in accordance with conventional screen printing methods.
  • a sheet of transparent material preferably acrylic, such as the sheet 12 described above, is placed below the screen in a jig that holds the plastic sheet in place, as will be described in more detail below.
  • the ink is then applied with a squeegee as is well-known in the art. It is important that the sheet of plastic be cleaned prior to the application of ink.
  • a quick method is to use a roller on the sheet, which picks up dirt and other material off the sheet.
  • the image 30 of Figure 3 is first applied to the back surface 14 of the sheet 11. It is preferable that the first image be of a lighter color or hue, such as yellow. However, a darker or contrasting color or hue can be used for the first image, such as black or dark-shade green.
  • the graduations 32 outline the uncolored gap 38 with uncolored subdivisions 48.
  • the circles 40 have uncolored numbers 42 formed therein. The image 32 is then inspected and, if acceptable, set aside to dry.
  • the screen having the second image 52 thereon is mounted and aligned with the first image 30. Alignment is much quicker and easier, because the lines 58 and numbers 62 will cover the corresponding uncolored areas with a slight overlap. This overlap allows a small error in the alignment without resulting in misalignment of the lines 58 and numbers 62 in the corresponding uncolored gaps 38 and number spaces 42 created by the first image.
  • the second image is then printed on the sheet using a contrasting darker color or hue. When viewed from the front surface 12 of the sheet 11, the darker lines 58 and numbers 62 will register perfectly within the gap 58 and number spaces 42 in the wider lighter line, even though the second image 52 may be slightly misaligned.
  • This application of the second image 52 is not an overlay of ink over the first image. Rather, it is the application of ink in the blank, un-inked areas or gaps 38 left by the first image 30, and only a slight overlap exists. As such, this method not only results in precise registration of the smaller darker line within the larger lighter line, it also reduces bleeding of one color into the other as can occur with an overlay. If the color of the first image 30 is totally opaque, then the second image 52 can have a width of two one-thousandths less than the width of the first image 30. It has been noted that confusion as to which side of the sheet is the top side may result from having the contrasting colors visible from both sides of the sheet of transparent material.
  • Figure 5 illustrates a third image 68 that consists of a grid pattern of thick, solid vertical lines 70 and horizontal lines 71 that are wider than the solid lines 57 and 58 of the second image 52 and slightly smaller than the graduations 32 and other lines 44 and 48, and circles 40 in the first image 32.
  • Additional vertical lines 72 and angled lines 74 are used, which are also of a smaller width than the corresponding vertical lines 44 and angled lines 46 shown in Figure 3.
  • the lines 70 are 1 to 2 one-thousandths of an inch smaller than the corresponding lines in the first image 30.
  • This third image 68 can be applied over the second image 52 as an overlay.
  • This overlay encapsulates the first two images 30 and 52, improving the appearance and protecting the images, thus increasing the useful life of the tool 10. It also aids users in determining which side of the tool 10 is the front surface 12 because the overlay only permits the viewing of the composite multicolor lines from the front surface 12.
  • the third image 68 ideally is of a color or hue that matches the first image 30, in this case a lighter color, such as yellow.
  • Figure 6 illustrates a screen printing apparatus for carrying out the method of the present invention.
  • a plastic sheet 76 placed in a jig 78 that holds the sheet 76 in place.
  • the screen 82 is mounted in correlators or registration clamps 84.
  • the jig clamps 80 may be adjusted to position the plastic sheet 76 precisely in position under the screen 82.
  • the correlators 84 also include similar adjustment mechanisms (not shown) for making minor adjustments in the position of the screen 82.
  • the screen 82 is rotated into position over the plastic sheet 76 where ink is applied and a squeegee pushes the screen 82 down on the plastic sheet 76, as is well known in the art.
  • the sheet 76 with the image printed thereon is then removed.
  • the present invention results in a higher production rate using less-skilled labor that achieves the same or better quality product. It is also to be appreciated that changes made be made without departing from the spirit and scope of the invention. For instance, the steps described above may be reversed, with the third image 68 applied to the sheet first, then the second image 52, and finally the first image 30. Alternatively, the third image can be eliminated and the first two images used. If the reverse steps are done, the images must be applied to the front side of the sheet so the second and first images will be visible. The drawback to this method is the possibility of parallax errors in viewing the lines on the top of a thick sheet of transparent material.
  • the present invention can be applied to sheets of thinner material that are then laminated together.
  • rolled sheets of 5 mil plastic can be printed by one of several methods described above, then cut and removably adhered to thin or thick transparent plastic sheets.
  • a single color may be applied to any combination of the two sheets and then aligned prior to adhering of the sheets.
  • Figures 7-10 illustrate another embodiment and further improvement in accordance with the present invention.
  • the same reference numbers will be used for the common subject matter illustrated in Figures 3-5 and 7-10.
  • Shown in Figure 7 is a first image 86 wherein the solid vertical lines 44 in each square 88 are broken at their vertical midpoint to leave an open gap 90.
  • Each angled line 46 is also broken at their junction with a vertical line 44 to leave the gap 90 open.
  • the first image 86 is identical to the first image 30 illustrated in Figure 3.
  • the vertical lines may have more than one gap 90 formed therein.
  • the gaps 90 may appear at regular or irregular intervals depending on the application, the scale, and the overall design.
  • Figure 8 illustrates a second image 92 having squares 56 that include a plurality of dots 94.
  • the dots 94 are positioned in each square 56 such that when the second image 92 is applied over the first image 86, the dots 94 will be located in the gaps 90 created in the vertical lines 44.
  • the dots 94 are of a larger size than the gaps 90 and of a contrasting color from the solid vertical lines 44 so they will be more readily visible to the user.
  • These dots 94 will aid in aligning and measuring subdivisions on the transparent measuring device. It is to be understood that the dots 94 may be the same size or smaller than the gaps 90 if desired.
  • An optional third image 96 is shown in Figure 9, which corresponds to the third image 68 illustrated in Figure 5.
  • the final composite image 98 consisting of the combination of the first image 86, the second image 92, and the third image 96, is shown in Figure 10, where the dots 94 are visible between the broken solid vertical lines 44 and the angled lines 46.
  • the process described above can be reversed if the composite image is to be applied to the opposite side of the transparent sheet.
  • the flexible sheet of material 17 is sized and shaped to completely cover only the surface of the rigid sheet of material 11 to which it is applied.
  • This flexible sheet 17 may be a single flexible sheet or formed from a plurality of flexible sheet segments separately adhered to the rigid sheet of material 11.
  • the lines may be formed on the flexible sheet of material 17, as described below, which is then applied to a blank piece of plastic of the same size.
  • 126 may be formed on the front or back sides 19,21 in the manner described above with respect to Figures 3-6 and 7-10.
  • the flexible sheet can be used under a cutting mat to hold it in place, and could be especially useful with a transparent cutting mat.
  • adhesive is not preferred because it is expensive, inconvenient, and can collect dirt and debris, it is recognized that adhesive may be necessary with certain materials or with smaller sizes of the flexible sheet material.
  • Conventional adhesive suitable for use with the non-static pressure sensitive film is readily commercially available in various degrees of tack and will not be described in detail herein.
