Title: Extendable collar

Description:
SUBJECT MATTER OF INVENTION 
     The present invention relates to the collar band construction of shirts and, in particular, dress and sport shirts. 
     BACKGROUND OF INVENTION 
     Conventional dress and sport shirts are ordinarily fabricated with collar constructions shaped and cut to a particular neck size. While many shirts suggest the shirt is adapted for a small range of sizes, as a practical matter that is not the case since the shirt collar bands are ordinarily made with non-stretchable components that have no give or yield once the shirt is buttoned to the neck. 
     Some shirts have been designed in efforts to provide some stretchability of the shirt in the neck. These efforts, insofar as known, do not provide as great a comfort as one would wish, does not have the same reliability and performance as might be desired for shirts having substantial qualities. In particular, prior designs may permit too much stretching and thereby result in shirts with stretched collars that have unsightly appearances and elastic or stretchable systems that do not stand up to wear and ultimately fail. These prior art systems are also uncomfortable to the wearer since the components used to permit adjustable neck sizes are frequently bulky and; uncomfortable to wear. 
     It is an object of the present invention to provide an improved shirt collar mechanism that allows a wearer to dynamically adjust a collar size over a defined length as, for example, one whole size while at all times maintaining an appropriate; appearance of the shirt collar when properly worn. A further object of the present invention is to provide a dynamically adjustable shirt collar that accommodates changes in a person&#39;s neck size on a long-term basis, as will occur when the wearer either gains or loses weight, or on a short-time basis when the wearer sneezes or otherwise flexes his neck. 
     A shirt collar designed primarily for dress or sports shirts is provided in which an adjustable collar is secured to the shirt body by a collar stand or collar band in a conventional fashion. An elongated length of fabric or strip is positioned within a fold in the collar band, with one end projecting through a slot or button hole in the collar band, and having a button secured to one end of the strip. The other end of the elongated strip is fixed to one side of an elastic member with the other side of the elastic member bar-tacked to the collar band. The button stitched to the one end of the strip is normally aligned with and interengaged with a button hole on the opposite side of the collar band when the shirt collar is closed.

     DETAILED DESCRIPTION OF EMBODIMENTS 
     The present invention may be used on a wide range of shirts including, for example, dress shirts and sports shirts made of a wide range of materials. Typically, fabrics may vary but in a particular example the fabrics used in practicing this invention may be blended fabrics such as a 60% cotton and 40% polyester fabric material. Other blended or non-blended material and synthetic fabrics, conventional in shirt manufacturing may be used. 
     A collar assembly  10  is secured to the collar stand  16 . The collar assembly  10  may have a variety of shapes and styles. In the embodiment illustrated, the collar is a pointed collar and is illustrated as secured to a collar stand  16  having a placket front  14 , although French fronts may also be used in practicing this invention. The collar stand  16  is in turn secured to the shirt body  12  as noted below. 
     The collar assembly  10  may be made in a wide range of styles and using a wide range of collar fabrication techniques. Typically, the collar assembly  10  is secured to a collar band or collar stand  16 . The collar assembly  10  is conventionally formed with an outer ply  18  and an integrally formed and fold over inner ply  20  (FIG.  2 ). Conventionally, an interfacing or stiffener (not shown) may be interposed between the inner and outer ply to give body to the collar assembly. Additionally, an inner self fabric  22  may also be stitched to the inner ply  20  with the inner self fabric  22  cut along a bias  23  at one end of the collar. Parallel stitching  24  extending from the collar point  28  securing the inner self fabric  22  and inner ply together forms an elongated pocket shaped to receive a collar stay. A similar construction may be provided at each collar point  28 . The collar band  16  may be secured to a band of the shirt body  12  at its neck opening with the border  30  secured by parallel lines of stitching  32  and  34 , extending through the collar band and the shirt body  12 . These bands of stitching,  32  and  34 , define a pocket between the collar band  16  and shirt body  12 . A slot  36  formed similar to a button hole is positioned in the pocket defined by the collar band  16  and shirt body  12 . An elongated strip of self fabric  42  having a preferred length of three inches extends through the slot  36  with a button  38  cross-stitched to the one end of the self fabric strip  42 . The other end of the self fabric strip  42  is stitched to one edge of a piece of elastic  45  having dimensions of ⅜″ long and ⅜″ wide. The other edge of this elastic fabric square  45  is bar tacked at  48  to the shirt body and/or collar band. The elastic  45  is preferably a composite material of 35% rubber thread (375W) and 65% polyester yard (150/300D) with the elastic formed on a suitable weaving crochet machine that weaves the rubber thread and yarn into an elasticity of 100:300. 
     The ⅜″ square dimension of the elastic fabric square material and the 3″ length of the self fabric strip  42  are selected to permit the button  38  to be stretched approximately ½″. 
     The button  38  is aligned with a button hole  50  at the upper end of the placket  14  when the shirt is closed and the elastic fabric  45  is not stretched. The button hole  50  may be formed in French fronts as well as in the placket illustrated. It is, conventionally, aligned with a series of other buttons and button holes in the shirt body.
