SUPPORT STAY

Abstract

A support stay for an article of clothing includes an elongated body with first and second ends, first and second generally parallel outer edges and a longitudinal axis disposed midway between the outer edges, and tabs extending longitudinally from each of the first and second ends. A series of generally v-shaped notches defined by an angle no greater than 30 are formed along each of the first and second generally parallel outer edges and extend from one outer edge past the longitudinal axis towards the other outer edge. The projected surface area of the elongated body excluding the areas formed by the notches may be between 80% and 95% of a first generally rectangular projected surface area bounded by the first and second ends and the first and second outer edges of the elongated member. This support stay is less visible through fabric in which it is inserted.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The invention will now be described with reference to the accompanying drawings. As illustrated in FIGS. 1 and 2, support stay 1 has an elongated body 10 with first and second ends 11, 12, first and second generally parallel outer edges 13, 14, and a longitudinal axis 15 disposed midway between the outer edges 13, 14. Elongated body 10 is further defined by a series of notches 16 formed along each of the first and second generally parallel outer edges 13, 14. One set of notches 16 extend from outer edge 13 past the longitudinal axis 15 and towards the other outer edge 14. The other set of notches 16 extend from outer edge 14 past the longitudinal axis 15 and towards the other outer edge 13. Stay 1 also includes tabs 17, 18 extending longitudinally from each of the first and second ends 11, 12.

[0020] In the illustrated embodiment, elongated body 10 assumes a zigzag configuration. Notches 16 are each generally v-shaped defined by an angle no greater than 30, e.g., from about 5 to 30, and preferably no greater than 20, e.g., from about 10 to 20. In the illustrated embodiment, this angle is 14. Also, in the illustrated embodiment, the area bounded by the first and second ends 11, 12 and the first and second edges 13, 14 defines a first generally rectangular projected surface area. The projected surface area of the elongated body, excluding the surface area formed by the notches 16 in the first generally rectangular projected surface area, is 88% of the first generally rectangular projected surface area in FIG. 1. In various embodiments, the projected surface area of the elongated body may be between 80% and 95% of this first generally rectangular projected surface area, or between 85% and 90% of this first generally rectangular projected surface area.

[0021] Applicant has found that by providing such a tighter zigzag configuration, as compared to the stay of aforementioned U.S. Pat. No. 6,202,221 (which has notches having a v-shaped angle of 45 and a projected surface area of 78.5% in the sinuous member portion thereof), the stay provides a flatter, less visible look when inserted in clothing, yet remains flexible. This is particularly important for applications where the stay is utilized as a support stay in sheer or see-through channeled garments, as it is especially desired that the stay is not visible through the fabric. Accordingly, this invention provides a support stay that lays flatter and is less visible than prior stays, while being sufficiently flexible, i.e., independently movable in two directions which are both orthogonal to the longitudinal direction. If desired, the maximum thickness of the elongated member and the tabs may be less than or equal to 0.1 inch, to further ensure the stay provides a flat look while the garment is worn.

[0022] Two adjacent notches 16 form a crest 19 therebetween, the crest terminating at the generally parallel outer edges 13, 14, respectively. The crests 19 may have rounded edges for reducing the coefficient of friction between the support stay and the article of clothing. Additionally, the edges 21, 22 of the tabs 17, 18 may be rounded also for reducing the coefficient of friction between the tabs and the article of clothing. Accordingly, the support stay of this invention has minimal potential of snagging fabric when worn or while being inserted into a garment during assembly of the garment.

[0023] In the embodiment shown in FIGS. 1 and 2, elongated body 10 and tabs 17, 18 are formed of a continuous piece of material, especially a corrosion-resistant material, such as a plastic material. Thus, the entire stay 1 including elongated body 10 and tabs 17 and 18 may be constructed of plastic and formed by conventional injection molding processes.

[0024] Often it is desired to stitch the stay to an article of clothing so that the stay remains relatively immobile with respect to the clothing. To achieve this, at least one of tabs 17, 18 may be made sufficiently thin for piercing by a stitching needle. If the tabs are made of plastic, the tabs may be sufficiently thin to be pierced without cracking the plastic tabs. Further, the tabs have sufficient length to receive stitching. In the illustrated embodiment, both tabs 17, 18 are appropriately sized and shaped for this purpose. As seen in FIG. 2, the tabs may have a continuously tapering thickness over at least a portion thereof, reducing toward distal ends of the tabs, such that a distal end of the tabs may have a maximum thickness of less than or equal to 0.030 inch. Tabs 17, 18 preferably have a length of at least 0.25 inch, more preferably at least 0.5 inch and a maximum thickness of less than or equal to 0.1 inch. At least one of the tabs may include at least one hole 25 which serves to guide a stitching needle. While various known plastic materials may be employed for forming the stay, Nylon 6/6 may advantageously employed to form a stay with integral elongate body and stitchable end tabs, as such material advantageously provides sufficient strength and durability at such reduced thicknesses.

[0025] FIG. 3 illustrates an embodiment similar to FIGS. 1 and 2. However, tabs 31, 32 are separate elements from elongated body 10, and are fixedly attached to the elongated body 10, for example, by friction interference fit or adhesive. FIG. 3 also illustrates where the tabs include multiple holes 25 for receiving a stitching needle. It is not necessary that all holes are used for stitching, but the provision of multiple holes allows one assembling the stay with a garment to select the specific holes for the given application.

[0026] FIGS. 4 and 5 illustrate another embodiment similar to FIGS. 1 and 2, with a similar elongated body configuration but with longer tabs 17 and 18 having circularly rounded ends 21 and 22. Providing a longer tab with a gradually continuously tapered thickness over a length of at least 0.5 inch, and more preferably at least 0.75 inch, in such further embodiment enables further improved performance in association with combined properties of strength and durability of the stay while further enabling sewability through the tabs, particularly when pre-formed holes are not provided in the tabs.

[0027] It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Although the figures illustrate certain embodiments, support stays with different dimensions and proportions are within the scope of this invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
