This application claims priority to and the full benefit of United States Non-provisional Patent Application Ser. No. 63/229,542 (filed Aug. 5, 2021, and titled “ALIGNMENT DEVICE FOR SEWING ALIGNMENT”), the entire contents of which are incorporated herein by reference.
Sewing, embroidery, and needlepoint are all important skills that often present unique challenges. Patience, close attention to detail, and a careful eye are just a few of the many requirements for mastery of these activities. One of the many ever-present challenges associated with sewing clothing involves aligning inseams along tubed fabric, such as for a sleeve, dress sinch-tie, or pant leg. Sewing children's clothing can be particularly tricky, as their sizing is often small, making the designs harder to maneuver.
Alignment of inseams is necessary for a number of reasons. First, proper alignment ensures an article of clothing is comfortable to wear, moves about the wearer as intended, and is as aesthetically pleasing as possible. Second, proper alignment ensures the inseams lay flat and do not bubble up, creating bumps in the clothing. Typically, inseams have a seam allowance, or an internal excess of fabric to ensure a secure seam, of around a quarter of an inch (sometimes as much as half an inch for some types of clothing). Seam allowances are a crucial part of any sewing project as they incorporate extra fabric into the design. In the instance of a piece of clothing, seam allowances ensure consistency in fit and longevity in wear. Without a proper seam allowance, clothing may unravel or fit incorrectly.
Since seam allowances are arguably the most important part of any sewing project, they are often one of the most tedious and difficult parts of the process. For small-shop owners and clothing manufacturers, it can take anywhere from a few to ten minutes to ensure one article has proper inseam alignment. When mass-producing clothing, these minutes add up, prolonging the process and hindering overall productivity. Even when manual alignment can be achieved with enough time and patience, it is often unreliable for producing consistent results. While it is often the “human-touch” to sewing and other needlework projects that make them so endearing, the resulting imperfections can be frustrating when trying to produce as many pieces of clothing as possible in a consistent way and in a reasonable amount of time.
What is needed is a device that streamlines the inseam alignment process as efficiently and consistently as possible. Accordingly, the present disclosure provides for an insertable alignment device for use in sewing projects, such as the construction of an inseam. In some aspects, an alignment device may be inserted inside a constructed tube of fabric and pushed against an inseam to keep it straight as the piece is finalized. The alignment device may properly align inseams in a timely fashion, such, for example and not limitation, in approximately thirty seconds, thereby expediting the entire sewing process, especially in the case of mass production of articles of clothing, such as dresses, pants, sweaters, and more. This may be particularly useful when ironing the inseams to make them smooth and straight. The alignment device may comprise a variety of sizes and materials, allowing the device to be used for multiple or specific projects, such as the manufacture of children's clothing, as well enabling the alignment device to interface with one or more various external devices, such as an iron.
In some embodiments, the alignment device may comprise at least one tip, a sleeve, and one or more holes. When the alignment device comprises one or more holes, one or more of the holes may allow the alignment device to be stored on a wall or other surface via an external hook or knob. In some implementations, the alignment device may comprise one or more extensions. When the alignment device comprises one or more extensions, each of the extensions may be coupled to the alignment device via at least one extension mechanism.
In some aspects, one alignment device may interface with one or more additional alignment devices in a nesting alignment system. Within such a nesting alignment system, one or more of the alignment devices may comprise a recess configured to house a smaller alignment device therein for storage purposes.
In some implementations, the alignment device of the present disclosure may comprise a plastic, wooden, vinyl, or magnetic material, or any combination thereof. In some embodiments, the alignment device may at least partially comprise a heat-resistant or thermoregulating material so it may interface with an external device, such as an iron.
The accompanying drawings that are incorporated in and constitute a part of this specification illustrate several embodiments of the disclosure and, together with the description, serve to explain the principles of the disclosure:
In the following sections, detailed descriptions of examples and methods of the disclosure will be given. The descriptions of both preferred and alternative examples, though thorough, are exemplary only, and it is understood to those skilled in the art that variations, modifications, and alterations may be apparent. It is therefore to be understood that the examples do not limit the broadness of the aspects of the underlying disclosure as defined by the claims.
The present disclosure describes an alignment device used in sewing and other needlework. The alignment device may facilitate the proper alignment of two or more parts of a project, such as when forming an inseam for an article of clothing, in a consistent, reliable, and efficient way. This proper alignment may allow the inseam to become smooth and even when the inseam is ironed after the sewing is complete.
