Foldable hair holding device

Abstract

A hair holding device includes a frame member having two spring arms separated from each other, and having a root portion joint together, the spring arms each include a free end portion having an extension extended toward each other, the spring arms include an engaging element provided in the extensions and selectively engaged with each other for coupling the extensions of the spring arms together, the frame member includes a clamping blade extended along a longitudinal central axis (X) of the frame member, the free end portion of the clamping blade is engageable with the extensions when the extensions are coupled together, and the clamping blade includes a curved bulge for engaging with the hair of the user.

1 . A hair holding device comprising:
 a frame member including a U-shaped structure having a first spring arm and a second spring arm separated from each other, said first and said second spring arms including a root portion where one end of each of the first and second spring arms joint together for allowing said first and said second spring arms to be folded relative to each other, said first and said second spring arms each including a free end portion and each including an extension extended from said free end portion, and said extensions of said first and said second spring arms being separated from each other for forming a space between said extensions of said first and said second spring arms,   said first spring arm including a depression provided in said extension of said first spring arm, and said second spring arm including a projection provided on said extension of said second spring arm for selectively engaging with said depression of said extension of said first spring arm and for selectively coupling said extensions of said first and said second spring arms together, and for forming an O-shaped configuration for said frame member and for selectively defining a chamber in said frame member when said depression and said projection of said extensions of said first and said second spring arms are engaged with each other,   said frame member including a clamping blade extended from said root portion of said first and said second spring arms, and extended into said chamber of said frame member, and extended along a longitudinal central axis (X) of said frame member, said clamping blade being located between said first and said second spring arms, and including a length large enough to have a free end portion contactable and engageable with said extensions of said first and said second spring arms when said extensions of said first and said second spring arms are coupled together, and said clamping blade including a curved bulge for selectively engaging into said chamber of said frame member, and for selectively engaging with a hair of a user, and said frame member including an included angle (θ) formed between either said first or said second spring arm and said longitudinal central axis (X), said frame member being manufactured with the following materials: 55% of 1,4-cyclohexanedimethanol (CHDM), 30% of ethylene glycol (EG), 10% of phosphotungstic acid (PTA), 1% of optical brightener, and 4% of polypropylene (PP) or butadiene-styrene copolymers, and   said clamping blade being resilient for allowing said clamping blade to be selectively separated from said extensions of said first and said second spring arms, and to be selectively and resiliently engaged with said extensions of said first and said second spring arms when said extensions of said first and said second spring arms are coupled together.   
     
     
         2 . The hair holding device as claimed in  claim 1 , wherein said frame member includes a thickness ranged between 0.8 and 1.2 mm. 
     
     
         3 . The hair holding device as claimed in  claim 2 , wherein said frame member includes a thickness of 0.9 mm. 
     
     
         4 . The hair holding device as claimed in  claim 1 , wherein said included angle (θ) of said frame member that is formed between either said first or said second spring arm and said longitudinal central axis (X) is ranged between 5 and 7 degrees.
