Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a hair curling device used to form and shape hair and, more particularly, to a hair curling device having a resilient sheath to keep the hair securely attached to a hair roller.
2. Description of the Related Art
Generally a variety of hair rollers which may be heated by steam, by electricity, and by a combination of steam and electricity have been used for imparting curls to straight strands of hair. More particularly, both professional hair stylists and individuals have used hair rollers to alter the shape and configuration of straight hair to approximate the appearance of natural curls.
Most prior art hair rollers have an elongated cylindrical configuration and may be solid or hollow. In use, the hair is separated into groups of strands, with each group of strands being tightly wrapped around the exterior cylindrical surface of the roller. The wrapped strand is then fixed relative to the roller by any suitable means such as a bobby pin. When the strand is unwrapped from the roller after a suitable period of time, curls will be formed along the length thereof.
However, the common suitable means can not provide the group of strands fixed securely and quickly, when a lot of or a little hair is separated into the groups of strands. The common suitable means such as a bobby pin get lost easily when detached with the hair roller.
Moreover, the conventional hair rollers cannot attach with the group of strands of hair securely because they usually have a flat and smooth outside surface so that the hair will slide with respect to the outside surface of the conventional hair roller easily to cause the curvature of the hair to be controlled hardly.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.

SUMMARY OF THE INVENTION

According to the present invention, a hair curling device includes a hair roller adapted to provide the hair wrapped and attached on it, and a resilient sheath adapted for surrounding the hair roller. The resilient sheath is adapted to be changed in the elastic deformation with respect to the outlines of the hair roller to surround and abut against the hair roller to keep a lot of or a little hair securely attached to the hair roller.
In view of the foregoing, it is an object of the present invention that the resilient sheath is adapted to be changed in the elastic deformation with respect to the outlines of the hair roller to surround and abut against the hair roller to keep a lot of or a little hair securely attached to the hair roller.
It is another object of the present invention that the hair curling device is adapted to be used to form and shape hair in any length.
It is another object of the present invention that the hair curling device only includes two elements to manufacture easily and faster.
It is yet another object of the present invention that the hair wrapped around and received in the spiral groove cannot slide with respect to the side edge so that it not only can save time but also control the curvature of the hair easily.
It is further object of the present invention that the second annular portion is firmly coupled with the periphery of the second end face to avoid the sheath and hair roller getting lost easily when detached.
