Adaptive hair clip

Abstract

A hair clip includes an upper clip piece defined with a lip portion, an arched body portion, an upper pivot portion and an upper handle portion; a lower clip piece defined with a tip portion, a base portion, a lower pivot portion, and a lower handle portion; and teeth extending downwards to the base portion. A hair clip is switchable between an open configuration and a closed configuration by operating upper and lower handle portions to have upper and lower clip pieces pivot on upper and lower pivot portions. When the hair clip is in the open configuration, the lip portion is apart from the tip portion for receiving hair therefrom. When the hair clip is in the closed configuration, the lip portion overbites the tip portion so that the hair in the hair-accommodating space is sharply separated from adjacent hair which is excluded from the hair clip.

What is claimed is: 
     
         1 . A hair clip, comprising:
 an upper clip piece being a single piece defined with a lip portion, an arched body portion, an upper pivot portion and an upper handle portion;   a lower clip piece defined with a tip portion, a base portion, a lower pivot portion coupled to the upper pivot portion, and a lower handle portion in cooperation with the upper handle portion, wherein a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodating space when the hair clip is in a working state with hair inside; and   a plurality of teeth extending from the arched body portion of the upper clip piece toward the base portion of the lower clip piece, and being long enough to bridge the hair-accommodating space between the arched body portion and the base portion;   wherein the hair clip in the working state is switchable between an open configuration and a closed configuration by operating the upper handle portion and the lower handle portion to have the upper clip piece and the lower clip piece pivot on the upper pivot portion and the lower pivot portion;   wherein when the hair clip is in the open configuration, the lip portion of the upper clip piece is apart from the tip portion of the lower clip piece to open a mouth for receiving hair therefrom; and   wherein when the hair clip is in the closed configuration, the lip portion of the upper clip piece overbites the tip portion of the lower clip piece so that the hair in the hair-accommodating space is sharply separated from adjacent hair which is excluded from the hair clip.   
     
     
         2 . The hair clip according to  claim 1 , wherein the teeth are allocated into at least two rows of teeth extending down to two sides of the base portion, or the lower clip piece is made of a plurality of separate strips and the teeth extends down to at least a gap between two of the separate strips or lower. 
     
     
         3 . The hair clip according to  claim 1 , wherein the teeth are of a linear structure substantially extending downwards, and each of the teeth has one end connected to the arched body portion of the upper clip piece and another end being a free end. 
     
     
         4 . The hair clip according to  claim 3 , wherein each of the teeth is formed of substantially uniform width or each of the teeth is formed of decreasing width toward the free end thereof. 
     
     
         5 . The hair clip according to  claim 1 , wherein each of the teeth is of a ring structure formed together with the arched body portion of the upper clip piece. 
     
     
         6 . The hair clip according to  claim 5 , wherein the ring structure is elastically deformable when pressed by hair. 
     
     
         7 . The hair clip according to  claim 1 , further comprising a deformation member disposed between the upper clip piece and the lower clip piece for adaptively changing an effective room of the hair-accommodating space. 
     
     
         8 . The hair clip according to  claim 7 , wherein the deformation member has two ends thereof coupled to the upper clip piece and the lower clip piece, respectively. 
     
     
         9 . The hair clip according to  claim 7 , wherein two ends of the deformation member are coupled to the same upper clip piece or the same lower clip piece. 
     
     
         10 . The hair clip according to  claim 7 , wherein the deformation member is of an elastically deformable structure. 
     
     
         11 . A hair clip, comprising:
 an upper clip piece being a single piece defined with a lip portion, an arched body portion, an upper pivot portion and an upper handle portion;   a lower clip piece defined with a tip portion, a base portion, a lower pivot portion coupled to the upper pivot portion, and a lower handle portion in cooperation with the upper handle portion, wherein a space created with the base portion and the arched body portion when the hair clip is in a rest state without hair inside is large enough to serve as a hair-accommodating space when the hair clip is in a working state with hair inside;   a plurality of teeth extending from the arched body portion of the upper clip piece toward the base portion of the lower clip piece; and   a deformation member disposed between the upper clip piece and the lower clip piece for adaptively changing an effective room of the hair-accommodating space;   wherein the hair clip in the working state is switchable between an open configuration and a closed configuration by operating the upper handle portion and the lower handle portion to have the upper clip piece and the lower clip piece pivot on the upper pivot portion and the lower pivot portion;   wherein when the hair clip is in the open configuration, the lip portion of the upper clip piece is apart from the tip portion of the lower clip piece to open a mouth for receiving hair therefrom; and   wherein when the hair clip is in the closed configuration, the lip portion of the upper clip piece overbites the tip portion of the lower clip piece to close mouth so that the hair in the hair-accommodating space is sharply separated from adjacent hair which is excluded from the hair clip.   
     
     
         12 . The hair clip according to  claim 11 , wherein the arch body portion includes at least one knuckle angle defined with linear and/or curved edges. 
     
     
         13 . The hair clip according to  claim 11 , wherein the deformation member is of an elastically deformable structure. 
     
     
         14 . The hair clip according to  claim 13 , wherein the deformation member has two ends thereof coupled to the upper clip piece and the lower clip piece, respectively. 
     
     
         15 . The hair clip according to  claim 13 , wherein the deformation member has two ends thereof coupled to the same one of the upper clip piece and the lower clip piece. 
     
     
         16 . The hair clip according to  claim 13 , wherein the deformation member has one end coupled to the upper or lower pivot portion and another end coupled to the lip portion of the upper clip piece or the tip portion of the lower clip piece. 
     
     
         17 . The hair clip according to  claim 11 , wherein the upper clip piece has a first indentation or notch in the lip portion of the upper clip piece, and the upper or lower pivot portion has a second indentation or notch, and the deformation band includes at least one rubber band looped around the first and second indentations or notches. 
     
     
         18 . The hair clip according to  claim 11 , wherein the upper clip piece has a first securing mechanism at the lip portion, the lower clip piece has a second securing mechanism at the lower handle portion, and the deformation band includes at least one rubber band having one end secured at the first securing mechanism and the other end penetrating through the upper and lower pivot portions to be secured at the second securing mechanism. 
     
     
         19 . The hair clip according to  claim 18 , wherein the first securing mechanism is a hook in a slot, and the second securing mechanism is a hook on a post.
