Collar Stay Device

Abstract

A collar stay device includes a stay body having a tapered first end and an expandable second end. The stay body includes first and second legs, which are integrally formed at the tapered first end and diverge toward the expandable second end. At least one of the legs includes a plurality of protrusions on an outer surface of a free end thereof. When the collar stay device is inserted into a prefabricated pocket in the collar of a shirt, the expandable second end of the stay body is contracted to place tension on the pocket and prevent movement of the collar stay device in the pocket.

1 . A collar stay device for use on a shirt having a collar, the collar stay device comprising:
 a stay body having a tapered first end and an expandable second end, the stay body including a first leg and a second leg integrally formed at the tapered first end, the first leg and the second leg diverging toward the expandable second end,   wherein at least one of the first leg and the second leg includes a plurality of protrusions on an outer surface of a free end thereof.   
   
   
       2 . The collar stay device according to  claim 1 , wherein each of the first leg and the second leg includes a plurality of protrusions on an outer surface of a free end thereof. 
   
   
       3 . The collar stay device according to  claim 1 , wherein the collar stay device is adapted to be inserted into a prefabricated pocket in a collar of a shirt, and the expandable second end of the stay body is contracted to place tension on the prefabricated pocket and prevent movement of the collar stay device in the prefabricated pocket. 
   
   
       4 . The collar stay device according to  claim 1 , wherein the stay body is composed of a non-metal material. 
   
   
       5 . The collar stay device according to  claim 4 , wherein the stay body is composed of a high tensile polymer material. 
   
   
       6 . The collar stay device according to  claim 1 , wherein the stay body has a length from the tapered first end to the expandable second end between 6.0 centimeters and 9.0 centimeters. 
   
   
       7 . The collar stay device according to  claim 1 , wherein the expandable second end of the stay body has an unconstrained width of approximately 2.0 centimeters. 
   
   
       8 . The collar stay device according to  claim 1 , wherein each the plurality of protrusions projects from the outer surface of the free end approximately 1 millimeter. 
   
   
       9 . A shirt comprising:
 a shirt body;   a collar coupled to the shirt body, the collar having two points and two pockets formed therein, each pocket located a corresponding point; and   two collar stay devices, each collar stay device removably inserted in a corresponding pocket of the collar, each collar stay device comprising:
 a stay body having a tapered first end and an expandable second end, the stay body including a first leg and a second leg integrally formed at the tapered first end, the first leg and the second leg diverging toward the expandable second end, at least one of the first leg and the second leg includes a plurality of protrusions on an outer surface of a free end thereof, 
   wherein the expandable second end of the stay body is contracted to place tension on the corresponding pocket and prevent movement of the collar stay device in the pocket.   
   
   
       10 . The shirt according to  claim 9 , wherein both the first leg and the second leg of stay body include a plurality of protrusions on an outer surface of a free end thereof. 
   
   
       11 . The shirt according to  claim 9 , wherein each the plurality of protrusions projects from the outer surface of the free end approximately 1 millimeter. 
   
   
       12 . The shirt according to  claim 9 , wherein the stay body is composed of a non-metal material. 
   
   
       13 . The shirt according to  claim 9 , wherein the stay body has a length from the tapered first end to the expandable second end between 6.0 centimeters and 9.0 centimeters, and wherein the expandable second end of the stay body has an unconstrained width of approximately 2.0 centimeters. 
   
   
       14 . The shirt according to  claim 13 , wherein the expandable second end of the stay body has a constrained width of approximately 1.0 centimeter, when the collar stay device is inserted in the pocket of the collar.
