Rollable Pillow and Furling Method Thereof

Abstract

A rollable pillow includes an elongated pillow body and a constriction assembly. The pillow body has a first end portion, a second end portion and a main body extended between the first end portion and the second end portion. The pillow body is normally extended in a closed position to form an arc-shaped support structure and able to be rolled up and furled to a furled condition to form a furled spiral structure. The constriction assembly includes an extensible constriction member arranged at a first predetermined position of an outer side of the pillow body and a first joining member arranged at a second predetermined position of the outer side of the pillow body such that the constriction member is able to be extended to connect with the first joining member to constrict the pillow body in the furled condition so as to retain the rollable pillow in the furled spiral structure.

What is claimed is: 
     
         1 . A rollable pillow, which is adapted for being worn on a neck of a user, comprising:
 an elongated pillow body having a first end portion, a second end portion and a main body extended between said first end portion and said second end portion, wherein said pillow body is normally extended in a closed position to form an arc-shaped support structure and able to be rolled up and furled to a furled condition to form a furled spiral structure; and   a constriction assembly comprising an extensible constriction member arranged at a first predetermined position of an outer side of said pillow body and a first joining member arranged at a second predetermined position of said outer side of said pillow body such that said constriction member is able to be extended to connect with said first joining member to constrict said pillow body in said furled condition so as to retain said rollable pillow in said furled spiral structure.   
     
     
         2 . The rollable pillow, as recited in  claim 1 , wherein said constriction assembly further comprises a constriction strap having a proximal end affixed to said outer side of said pillow body and a distal end coupling with said constriction member, wherein said constriction strap is extended to wrap around said pillow body in said furled condition until said constriction member reaches said first joining member and connects with said first joining member so that said constriction strap surrounding and constricting said pillow body in said furled condition substantially retains said rollable pillow in said furled spiral structure.
