1. Field of the Invention
The present invention relates to apparel. The invention concerns, more particularly, an article of apparel that incorporates a pleated structure with secondary elements secured to and extending along at least one fold of the pleated structure. 2.
Description of Background Art
An article of apparel generally flexes, stretches, or otherwise deforms to accommodate movements of an individual wearing the article of apparel. Factors that contribute to the degree to which an article of apparel accommodates specific movements of the individual include the materials forming the article of apparel, the relative shapes of the article of apparel and the individual, and the various structural features incorporated into the article of apparel. Accordingly, the process of designing an article of apparel that accommodates specific movements of the individual involves considering each of these factors, as well as the intended use and desired aesthetics of the article of apparel.
Materials, relative shapes, and structural features cooperatively determine the degree to which an article of apparel accommodates movements of the individual. Many articles of apparel incorporate textiles, and the specific textile selected for a particular apparel application may be selected based upon the inherent drape and stretch properties of the textile, for example. In general, textiles with greater drape and stretch properties will accommodate the greatest range of motion in the individual. With regard to relative shapes, an article of apparel with dimensions that are similar to or greater than the dimensions of the individual will generally accommodate the greatest range of motion in the individual. Finally, structural features may also be utilized to enhance the degree to which an article of apparel accommodates movements of the individual. For example, articles of apparel may be designed to increase in length through an extension structure, as disclosed in U.S. Pat. No. 5,138,717 to Tolton. In addition, an article of apparel may be structured to effectively expand by incorporating pleated structures into defined areas of the article of apparel. Although materials, relative shapes, and structural features individually enhance the range of motion provided by an article of apparel, the process of designing an article of apparel generally involves considering the cooperative effect of various factors. That is, materials, relative shapes, and structural features cooperatively define the range of motion provided by an article of apparel.
The range of motion provided by an article of apparel is of particular interest to athletes when utilizing the article of apparel during athletic activities, whether practice or competition. For example, the game of golf requires that the arms of the individual freely move relative the torso of the individual, and that the torso rotate relative the legs of the individual. That is, an article of apparel, such as a shirt or jacket, that is suitable for the game of golf permits a wide range of motion in the upper body of the individual. Similarly, articles of apparel for sports such as running, biking, tennis, football, soccer, and baseball also permit a wide range of motion in areas of the individual that are utilized during those particular athletic activities.
The present invention relates to an article of apparel having a pleated structure with a material element and a bonding element. The material element is formed from a two-dimensional material and has a first surface and an opposite second surface. The material element also has at least one fold. Portions of the first surface positioned adjacent to the fold and on opposite sides of the fold are placed in an overlapping configuration. The bonding element is secured to the first surface, and the bonding element is positioned adjacent to the fold and extends along the fold.
The two-dimensional material forming the material element may be a textile or polymer sheet, for example. One of the first surface and the second surface may form an exterior surface of the article of apparel, and another of the first surface and the second surface may form an interior surface of the article of apparel. In other embodiments, the fold may form a portion of a pleated structure in the article of apparel, and the pleated structure may be positioned in the article of apparel to extend along a back area of the torso region when worn.
The advantages and features of novelty characterizing the present invention are pointed out with particularity in the appended claims. To gain an improved understanding of the advantages and features of novelty, however, reference may be made to the following descriptive matter and accompanying drawings that describe and illustrate various embodiments and concepts related to the invention.
The foregoing Summary of the Invention, as well as the following Detailed Description of the Invention, will be better understood when read in conjunction with the accompanying drawings.
Introduction
The following discussion and accompanying figures disclose various articles of apparel that incorporate pleated structures in accordance with the present invention. Although the articles of apparel are depicted as being jackets and a pair of pants, the pleated structures may be incorporated into a variety of apparel types. More particularly, one or more of the pleated structures may be incorporated into headwear, short-sleeved shirts, long-sleeved shirts, suits, dresses, coats, vests, shorts, or skirts, for example. Additionally, one or more of the pleated structures may be incorporated into articles of apparel that are intended for use during casual wear or athletic activities. Accordingly, the jackets and pair of pants disclosed herein are intended to provide examples of the variety of apparel types that may incorporate the pleated structures.
First Pleat Configuration
With reference to
Article of apparel 100 is a jacket having a configuration that is suitable for a variety of activities, including athletic activities associated with the game of golf. As discussed in the Background of the Invention section above, the game of golf requires that the arms of an individual freely move relative the torso of the individual, and also requires that the torso rotate relative the legs of the individual. That is, an article of apparel that is suitable for the game of golf permits a wide range of motion in the upper body of the individual. Pleated structure 110 enhances or otherwise increases the range of motion permitted by article of apparel 100. More particularly, pleated structure 110 changes from a non-expanded configuration to an expanded configuration upon the application of a generally horizontal tensile force in the back area of torso region 101. This change from the non-expanded configuration to the expanded configuration increases the overall dimensions of torso region 101 and decreases the degree to which apparel 100 restricts motion of the individual.
Article of apparel 100 is formed from a plurality of flexible and generally two-dimensional material elements that are sewn, bonded, adhered, or otherwise joined together to form torso region 101 and arm regions 102. Similarly, pleated structure 110 is formed from a plurality of flexible and generally two-dimensional material elements that are joined together. As utilized with respect to the present invention, the term “two-dimensional material” or variants thereof is intended to encompass generally flat materials exhibiting a length and a width that are substantially greater than a thickness. Accordingly, suitable materials for article of apparel 100 and pleated structure 110 include various textiles, polymer sheets, or combinations of textiles and polymer sheets, for example. Textiles are generally manufactured from fibers, filaments, or yarns that are, for example, either (a) produced directly from webs of fibers by bonding, fusing, or interlocking to construct non-woven fabrics and felts or (b) formed through a mechanical manipulation of yarn to produce a woven fabric. The textiles may incorporate fibers that are arranged to impart one-directional stretch or multi-directional stretch, and the textiles may include coatings that form a breathable and water-resistant barrier, for example. The polymer sheets may be extruded, rolled, or otherwise formed from a polymer material to exhibit a generally flat aspect. Two-dimensional materials may also encompass laminated or otherwise layered materials that include two or more layers of textiles, polymer sheets, or combinations of textiles and polymer sheets. In addition to textiles and polymer sheets, other two-dimensional materials may be incorporated into article of apparel 100 and pleated structure 110.
Pleated structure 110 is defined in a two-dimensional material element 105 that forms at least a portion of the back area of torso region 101, as depicted in
Pleated structure 110 includes four folds 111a-111d, four bonding elements 112a-112d, and a pair of stitched areas 113. Folds 111a-111d are folded portions of material element 105 that are substantially parallel to each other and extend through the length of material element 105. Bonding elements 112a-112d are respectively positioned adjacent to folds 111a-111d and bond overlapping surfaces of material element 105 to each other. Stitched areas 113 are located in upper and lower portions of pleated structure 110 and limit the degree to which the upper and lower portions may expand.
Pleated structure 110 is depicted in cross-section in
With regard to fold 111b, material element 105 folds at fold 111a such that portions of exterior surface 106 positioned adjacent to fold 111b and on opposite sides of fold 111b are placed in an overlapping configuration. That is, material element 105 is folded such that portions of exterior surface 106 face each other along fold 111b. Bonding element 112b is positioned adjacent to fold 111b and extends along fold 111b. More particularly, bonding element 112b is positioned between the portions of exterior surface 106 positioned adjacent to fold 111b , and bonding element 112b bonds these portions of exterior surface 106 to each other.
Folds 111a and 111b effectively form a z-shaped configuration in pleated structure 110. With reference to
The configuration of folds 111c and 111d are substantially similar to the configuration of folds 111a and 111b. With regard to fold 111c, material element 105 folds inward at fold 111c such that portions of interior surface 107 positioned adjacent to fold 111c and on opposite sides of fold 111c are placed in an overlapping configuration. Bonding element 112c is positioned adjacent to fold 111c and extends along fold 111c. More particularly, bonding element 112c is positioned between the portions of interior surface 107 positioned adjacent to fold 111c, and bonding element 112c bonds these portions of interior surface 107 to each other.
With regard to fold 111d, material element 105 folds at fold 111d such that portions of exterior surface 106 positioned adjacent to fold 111d and on opposite sides of fold 111d are placed in an overlapping configuration. That is, material element 105 is folded such that portions of exterior surface 106 face each other along fold 111d. Bonding element 112d is positioned adjacent to fold 111d and extends along fold 111d. More particularly, bonding element 112d is positioned between the portions of exterior surface 106 positioned adjacent to fold 111d , and bonding element 112d bonds these portions of exterior surface 106 to each other.
Bonding elements 112a-112d may be a thermoplastic polymer, for example, that forms bonds with material element 105 through the application of sufficient heat and pressure, thereby bonding portions of the surfaces of material element 105 together. Alternately, bonding elements 112a-112d may be a material that forms the bonds through radio frequency or ultrasonic bonding processes, for example. In some embodiments, and as depicted in the figures, bonding elements 112a-112d are two-dimensional materials. With regard to the thermoplastic polymer, the amount of heat and pressure applied to form the bonds depends upon the specific material forming bonding elements 112a - 112d, which may be polyurethane, polyamide, polyester, polyolefin, or vinyl. Suitable thermoplastic polymers formed from these materials and having the configuration of a polymer tape may be supplied by Bemis Associates, Inc. of Shirley, Mass., United States. In general, the heat and pressure induces bonding elements 112a-112d to soften or melt so as to infiltrate the structure of material element 105. Upon subsequent cooling, bonding elements 112a-112d becomes securely bonded to portions of the surfaces of material element 105, thereby bonding the portions of the surfaces together without the necessity of stitching or other adhesive elements. A further benefit to the use of bonding elements 112a- 112d relates to the resulting configuration of the areas bonded by bonding elements 112a-112d. In general, bonding elements 112a-112d add little additional thickness to pleated structure 110 and permit the areas around folds 111a-111d to lie in a generally flat configuration.
Bonding elements 112a- 112d are discussed as being separate from material element 105 and bonded to material element 105. In some embodiments, bonding elements 112a-112d be portions of material element 105 that are bonded together through the application of heat and pressure, for example. That is, pleated structure 110 may be formed by bonding portions of material element 105 directly to each other, thereby negating the presence of separate bonding elements 112a-112d.
In the non-expanded configuration, fold 111a is positioned immediately adjacent to fold 111c. In addition, the portions of material element 105 that extend between folds 111a and 111b and extend between folds 111c and 111d lie in a generally co-planar relationship with each other. In the expanded configuration, however, fold 111a is separated from fold 111c, and the portions of material element 105 that extend between folds 111a and 111b and extend between folds 111c and 111d bend or otherwise extend outward to accommodate the separation between folds 111a and 111c. That is, the tensile force in the direction of arrows 108 causes portions of material element 105 to bend or otherwise extend outward and form a separation between folds 111a and 111c, thereby increasing the overall dimensions of torso region 101 and decreasing the degree to which apparel 100 restricts motion of the individual.
Pleated structure 110 provides a combination of advantages that are suitable for a variety of apparel applications. As a first matter, pleated structure 110 readily converts from the non-expanded configuration to the expanded configuration upon the application of a force in the direction of arrows 108, thereby increasing the overall dimensions of torso region 101 and decreasing the degree to which apparel 100 restricts motion of the individual. When the tensile force is removed or lessened, however, pleated structure 110 readily returns to the non-expanded configuration. More particularly, the configuration of folds 11a-11d and the use of bonding elements 112a-112d imparts a tendency in pleated structure 110 to return to the non-expanded configuration. As another matter, pleated structure 110 forms a low-profile element of article of apparel 100. In the non-expanded configuration, bonding elements 112a-112d align the various segments of material element 105 along the direction of arrows 108. That is, material element 105 has a relatively planar configuration that does not add significant bulk to article of apparel 100 when in the non-expanded configuration. Pleated structure 110 is, therefore, a relatively inconspicuous element of article of apparel 100 and is suitable for apparel where aesthetics are considered during the design process.
Second Pleat Configuration
With reference to
Article of apparel 200 is formed from a plurality of flexible and generally two-dimensional material elements that are sewn, bonded, adhered, or otherwise joined together to form torso region 201 and arm regions 202′. Similarly, pleated structure 210 is formed from a plurality of flexible and generally two-dimensional material elements that are joined together. Pleated structure 210 is defined in a two-dimensional material element 205 that forms at least a portion of the back area of torso region 201, as depicted in
Pleated structure 210 includes four folds 211a-211d, two bonding elements 212a, two bonding elements 212c, and a pair of stitched areas 213. Folds 211a-211d are folded portions of material element 205 that are substantially parallel to each other and extend through the length of material element 205. Bonding elements 212a are positioned adjacent to fold 211a, and bonding elements 212c are positioned adjacent to fold 211c. Stitched areas 213 are located in upper and lower portions of pleated structure 210 and limit the degree to which the upper and lower portions may expand.
Pleated structure 210 is depicted in cross-section in
With regard to fold 211b, material element 205 folds at fold 211b such that portions of exterior surface 206 positioned adjacent to fold 211b and on opposite sides of fold 211b are placed in an overlapping configuration. That is, material element 205 is folded such that portions of exterior surface 206 face each other along fold 211b. Unlike pleated element 110, no bonding element is positioned adjacent to fold 211b in this embodiment. In some embodiments, however, one or more bonding elements may be secured to material element 205 adjacent to fold 211b.
Folds 211a and 211b effectively form a z-shaped configuration in pleated structure 210. With reference to
The configuration of folds 211c and 211d are substantially similar to the configuration of folds 211a and 211b. With regard to fold 211c, material element 205 folds inward at fold 211c such that portions of interior surface 207 positioned adjacent to fold 211c and on opposite sides of fold 211c are placed in an overlapping configuration. That is, material element 205 is folded such that portions of interior surface 207 face each other along fold 211c. Bonding elements 212c are positioned adjacent to fold 211c, on opposite sides of fold 211c, and are secured to interior surface 207 along fold 211c. More particularly, bonding elements 212c are separately secured to interior surface 207 and positioned adjacent to opposite sides of fold 211c. Unlike bonding element 112c , however, bonding elements 212c do not bond portions of interior surface 207 to each other. Rather, only one surface of bonding elements 212c is bonded to interior surface 207.
With regard to fold 211d, material element 205 folds at fold 211d such that portions of exterior surface 206 positioned adjacent to fold 211d and on opposite sides of fold 211d are placed in an overlapping configuration. That is, material element 205 is folded such that portions of exterior surface 206 face each other along fold 211d. Unlike pleated element 110, no bonding element is positioned adjacent to fold 211d in this embodiment. In some embodiments, however, one or more bonding elements may be secured to material element 205 adjacent to fold 211d.
The materials forming bonding elements 212a and 212c may be similar to the materials that form bonding elements 112a-112d. As an alternative, bonding elements 212a and 212c may be formed from a material that is substantially similar to the material forming material element 205, and bonding elements 212a and 212c may include a thermoplastic material on one surface that effectively bonds or otherwise secures the material to interior surface 207. That is, bonding elements 212a and 212c may be formed from the same material as other portions of article of apparel 200, and bonding elements 212a and 212c may include another material that secures bonding elements 212a and 212c to interior surface 207.
In the non-expanded configuration, fold 211a is positioned immediately adjacent to fold 211c. In addition, the portions of material element 205 that extend between folds 211a and 211b and extend between folds 211cand 211d lie in a generally co-planar relationship with each other. In the expanded configuration, however, fold 211a is separated from fold 211c, and the portions of material element 205 that extend between folds 211a and 211b and extend between folds 211c and 211d bend or otherwise extend outward to accommodate the separation between folds 211a and 211c. That is, the tensile force in the direction of arrows 208 causes portions of material element 205 to bend or otherwise extend outward and form a separation between folds 211a and 211c , thereby increasing the overall dimensions of torso region 201 and decreasing the degree to which apparel 200 restricts motion of the individual.
Pleated structure 210 provides a combination of advantages that are suitable for a variety of apparel applications. As a first matter, pleated structure 210 readily converts from the non-expanded configuration to the expanded configuration upon the application of a force in the direction of arrows 208, thereby increasing the overall dimensions of torso region 201 and decreasing the degree to which apparel 200 restricts motion of the individual. When the tensile force is removed or lessened, however, pleated structure 210 readily returns to the non-expanded configuration. More particularly, the configuration of folds 211a-211d and the use of bonding elements 212a-212d imparts a tendency in pleated structure 210 to return to the non-expanded configuration. As another matter, pleated structure 210 forms a low-profile element of article of apparel 200. In the non-expanded configuration, bonding elements 212a-212d align the various segments of material element 205 along the direction of arrows 208. That is, material element 205 has a relatively planar configuration that does not add significant bulk to article of apparel 200 when in the non-expanded configuration. Pleated structure 210 is, therefore, a relatively inconspicuous element of article of apparel 200 and is suitable for apparel where aesthetics are considered during the design process.
In pleated structure 210, the pair of bonding elements 212a are positioned adjacent and on opposite sides of fold 211a, and the pair of bonding elements 212c are positioned adjacent and on opposite sides of fold 211c. As an alternative to the configuration discussed above, the pair of bonding elements 212a may be replaced by a single bonding element that is centered over fold 211a and also folded with fold 211a. That is, the space between bonding elements 212a may be eliminated such that a single bonding element is secured to interior surface 207 and folded at fold 211a. Similarly, the pair of bonding elements 212c may be replaced by a single bonding element that is centered over fold 211c and also folded with fold 211c. Upon the application of heat and pressure, for example, the single bonding elements may form a defined and crisp fold at each of folds 211a and 211c. In a similar manner, each of bonding elements 122a-122d may be centered over folds 111a -111d, folded with folds 111a-111d, and bonded to effectively form a structure that is identical to pleated structure 110.
Additional Apparel Configurations
Pleated structures 110 and 210 are discussed above and depicted in the figures as being located in a back area of either torso region 101 or torso region 201. This configuration increases the overall dimensions of torso regions 101 and 201 in response to a tensile force. In further embodiments of the invention, either of pleated structures 110 and 210 may be located in other portions of an article of apparel. For example, either of pleated structures 110 and 210 may be located in a front area of the apparel, or a pair of pleated structures having the configuration of either of pleated structures 110 and 210 may be located on opposite side areas of the apparel.
