DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a hair clip.
It is well-known for a hair clip to be used for holding hair or for fashioning a hairstyle.
Such a clip comprises two comb-shaped elements mounted pivotably in relation to one another, which are usually held in a brought-together position by an elastic member such as a kickover spring. The teeth of these two elements have a shape which is curved to a greater or lesser extent and are offset from one element to the other so as to interlock when the two elements are brought together.
This type of clip has the disadvantage of not holding very well in the hair and of tending, therefore, to slide when the head is moved.
Indeed, these movements generate a centrifugal force on the clip in the opposite direction to that of the teeth which causes the two comb-shaped elements to move apart on account of the curved shape of the teeth and the weak elastic force of the spring.
Moreover, such a clip does not perform very effective holding of the hair on account of the fact that the teeth are not interlocked, or are only weakly interlocked, when the clip is placed in the hair. The hair is not held very well by these teeth and can escape relatively easily from the clip.
The present invention aims to eliminate these disadvantages.
SUMMARY OF THE INVENTION
The clip to which the invention relates comprises, in a manner known per se, two comb-shaped elements mounted pivotably in relation to one another and usually held in a brought-together position by an elastic member.
According to the invention, the teeth of one comb-shaped element are arranged opposite the teeth of the other comb-shaped element and one of two opposite teeth has at least one opening in which the other tooth engages when the two elements are in the completely or partially brought-together position.
Thus, the teeth of the two comb-shaped elements do not interlock but interpenetrate when the clip is completely or partially closed. The mass of hair gripped between the two elements tends to press the teeth against one another, thus generating friction between the teeth and creating a self-locking effect of the elements. This self-locking effect makes perfect holding of the clip in the hair possible even in the event of relatively sharp movements of the head.
Moreover, the longitudinal edges of the teeth come close to one another when the clip is completely or partially closed and together delimit numerous chicanes for clamping the hair. These chicanes make a clamping of the teeth in relation to one another possible, and this brings about the immobilization of the comb-shaped elements and contributes to good holding of the clip in the hair.
Preferably, the teeth have a base part of relatively slight curvature, an intermediate part of relatively great curvature extending over an arc of roughly 90.degree., and a free end part of relatively slight curvature.
The free end parts of two opposite teeth thus interpenetrate at a great angle, which favors the coming into mutual contact of these teeth during gripping of the hair and, therefore, the self-locking effect.
The teeth may have any shape that is suitable for increasing the clamping of the hair between them.
Thus, the opening made in one tooth may be of oval, oblong or triangular shape, or may comprise, on the same side as the free end of the tooth, a widened part favoring the introduction of the tooth situated opposite and, on the same side as the base of the tooth, a narrowed part favoring the clamping of the hair. The same tooth may also have two openings aligned longitudinally, in which the tooth situated opposite engages successively during the bringing-together of the two comb-shaped elements.
As for a tooth without an opening, this may have a non-rectilinear shape and/or a section which is variable over its length, favoring the arrangement of chicanes for clamping the hair. This tooth may also have an undulating shape, or a succession of widened portions and narrowed portions, or on the other hand a widened part at its base and a n
