Abstract

The hair clip consists of a single moulded piece in the form a of a grip in two sections hinged together at one end, with a fastening (F) at the other end. The fastening (F) is formed by bending one of the sections to form a clasp for a catch on the other piece. The two sections are formed of a synthetic, semi-resilient material. The catch has a width roughly one quarter to one third of its length. The angle at which the two parts are moulded is between fifteen and thirty degrees, preferably twenty degrees.

Description

L'invention se rapporte à une pince et notamment à une barrette destinée à maintenir une mèche de cheveux. The invention relates to pliers and in particular to a barrette intended to hold a lock of hair.

Actuellement, les barrettes sont réalisées par assemblage d'au moins trois pièces : un bandeau extérieur métallique ou plastique dont les extrémités sont repliées pour constituer, l'une le charnon de l'articulation de la contre-piece ou loquet, l'autre le fermoir ou gâche de celui ci, ce loquet et un axe d'articulation. Currently, the bars are produced by assembling at least three parts: an external metal or plastic strip whose ends are folded back, one forming the knuckle of the joint of the counter-piece or latch, the other the clasp or keeper thereof, this latch and a hinge pin.

Cette conception fait intervenir un cout de main-d' eeuvre de montage incompatible avec la faible valeur vénale d'un tel article. This design involves a labor cost of assembly incompatible with the low market value of such an article.

Par ailleurs de telles barrettes n'offrent guere de securité d'emploi par le fait que lamise en place du loquet qui nécessite un dépla- cernent lateral de oelui-ci par rapport au bandeau porte-gâche n'est obtenu que par le jeu existant dans l'articulation et même l'élasticité du métal formant le loquet est insuffisante Si la meche à retenir est peu épaisse. In addition, such bars offer little security of use by the fact that the placing of the latch which requires a lateral displacement of it relative to the striker strip is obtained only by the existing play in the joint and even the elasticity of the metal forming the latch is insufficient If the wick to be retained is not very thick.

Il existe des barrettes de structure beaucoup plus compliquée dans lesquelles une lame de compression élastique est intercalée entre le
bandeau et la contre-pièce, celle-ci étant verrouillée latéralement par des doigts élastiques uncinés.
There are bars of much more complicated structure in which an elastic compression blade is interposed between the
headband and the counterpiece, the latter being locked laterally by uncined elastic fingers.

Si une telle barrette offre une sécurité d'emplot maximale, son coût de fabrication est tel que celle-ci est forcément de vente limitée. If such a bar offers maximum job security, its manufacturing cost is such that it is necessarily of limited sale.

Bien entendu il existe des barrettes de luxe beaucoup plus sophistiquées avec bandeaux en matières naturelles comme l'os, l'iveire, l'écaille, le bois ou en matière synthétique de remplacement. Ces bar- rettes dont le prix est relativement très élevé, sont d'une conception "mécanique" dans laquelle on nia pas hésité à multiplier le nombre de pièces, l'important n'était pas le prix mais d'éviter la perte. Of course there are much more sophisticated luxury bars with bands in natural materials such as bone, ivory, tortoiseshell, wood or synthetic replacement. These bars, the price of which is relatively very high, are of a "mechanical" design in which there was no hesitation in multiplying the number of parts, the important thing was not the price but to avoid loss.

L'invention entend proposer une- barrette d'un coût très bas,rendu @ossible lar le faut qu'aussitôt après moulage, celle-ci est utilisable sans aucune opération ultérieure. The invention intends to propose a bar of very low cost, made @ possible lar the need that immediately after molding, it can be used without any subsequent operation.

La particularité de cette barrette est d'être réalisée en une seule pièce par moulage d'un matériau synthétique semi-résilient, l'élément mobile étant pendant ce moulage dans une position formant un angle sen sible par rapport à la position qu'il prendra lorsqu'il sera engage dans le fermoir. The special feature of this bar is that it is made in one piece by molding a semi-resilient synthetic material, the mobile element being during this molding in a position forming a sensitive angle with respect to the position it will take. when it is engaged in the clasp.

D'autresparticularités et avantages apparaitront à la lecture de la description et des revendications qui vont suivre lesquelles sont faites en regard des dessins annexes sur lesquels : - la figure 1 est une vue élévation d'une barrette selon l'invention et dont les éléments sont dans la position de moulage. Other particularities and advantages will appear on reading the description and the claims which follow which are made with reference to the accompanying drawings in which: - Figure 1 is an elevation view of a bar according to the invention and the elements of which are in the molding position.

- la figure 2 est une vue en plan par dessous montrant la position des éléments dans la phase précédant le verrouillage..- Figure 2 is a plan view from below showing the position of the elements in the phase before locking.

- la figure 3 et 4 montrent respectivement la barrette, en élévation, et plan vu par dessous, apres fermeture.- Figure 3 and 4 respectively show the bar, in elevation, and plan seen from below, after closure.

Comme on le voit sur ces figures, cette barrette est moulée en une seule pièce dans la position visible à la fig. 1, c'est-à-dire que le bandeau extérieur B dont l'une des extrémités est repliée en bec pour former le fermoir F, se poursuit au-del du repliement A pour constituer le deuxième élement de la pince : le loquet L. As can be seen in these figures, this bar is molded in one piece in the position visible in FIG. 1, that is to say that the outer strip B, one of the ends of which is folded back into a beak to form the clasp F, continues beyond the folding A to constitute the second element of the clamp: the latch L .

Le moulage s'effectue en position-ouverte (fig. 1) le loquet L fait alors un-angle compris entre 15 et 300 par rapport à sa position fermée (fig. 3) le sommet de l'angle se situant-aux environs de x-x. The molding is carried out in the open position (fig. 1) the latch L then makes an angle between 15 and 300 with respect to its closed position (fig. 3) the apex of the angle being-around xx.

La paroi intérieure du bandeau est pourvue de picots..R ou autres moyens d'accrochage des cheveux. The inner wall of the headband is provided with pins..R or other means for hanging the hair.

La figure 2 montre que pour passer de la position ouverte de la figure 1 a la position de fermeture de la figure 3, il faut déformer le loquet L , d'une part dans la zone de l'axe Y-Y de manière à ce que ce loquet prenne une position-angulaire telle que son éxtrémité libre évite l'extrémité du bec du fermoir F, et d'autre part, dans-la zone de l'axe .x-x pour que cette extrémité se situe au dessous du bec de F. Une pression sur L conjuguée à la déformation temporaire selon Y-Y étant suivie d'un relâchement permet à l'élasticité du matériau de péaligner le loquet dans l'axe du.bandeau alors que l'extrémité de ce loquet est engagée au-dessous du bec du fermoir. Figure 2 shows that to move from the open position of Figure 1 to the closed position of Figure 3, it is necessary to deform the latch L, on the one hand in the area of the axis YY so that this latch takes an angular position such that its free end avoids the end of the beak of the clasp F, and on the other hand, in the zone of the axis .xx so that this end is located below the beak of F. A pressure on L combined with the temporary deformation according to YY being followed by a relaxation allows the elasticity of the material to puncture the latch in the axis of the strip while the end of this latch is engaged below the spout of the clasp.

Ledit loquet subit donc une double déformation, d'abord selon l'axe x-x lorsque la pression- s'exerce en P1, puis selon Y-Y lorsque la pres- sion se poursuit dans le sens P2. Said latch therefore undergoes a double deformation, first along the axis x-x when the pressure is exerted in P1, then along Y-Y when the pressure continues in the direction P2.

Le résultat est visible sur les fig. 3et 4.  The result is visible in fig. 3 and 4.

Pour ouvrir la barrette, il faut faire les operations inverses appuyer sur l'extrémité libre de L, pousser dans le sens de P2, relacher la pression. To open the bar, reverse operations must be carried out, press the free end of L, push in the direction of P2, release the pressure.

Bien que réalisée en un seul bloc, cette barrette produit tous les mouvements des barrettes classiques sans en avoir les inconvénients. Although produced in a single block, this bar produces all the movements of conventional bars without having the disadvantages.

Notamment la déformation temporaire selon Y-Y, qui correspond au jeu de l'articulation des barrettes traditionnelles constitue un moyen de sécurité s'opposant à l'ouverture intempestive. In particular the temporary deformation according to Y-Y, which corresponds to the play of the articulation of the traditional bars constitutes a safety means opposing the untimely opening.

Avantageusement, cette barrette. est moulee en polyamide ou en acé- tate ou aceto-butyrate de cellulose car ces matériaux sont doués d'une resilience intéressante en particulier en ce qui concerne la déformation transversale selon Y-Y. Advantageously, this bar. is molded from polyamide or cellulose acetate or aceto-butyrate because these materials are endowed with an interesting resilience, in particular with regard to transverse deformation along Y-Y.

Ce matériau est néanmoins suffisamment rigide pour que sous l'effet de la poussée P1, la déformation reste localisée à la zone voisine de x-x. This material is nevertheless sufficiently rigid so that under the effect of the thrust P1, the deformation remains localized in the region close to x-x.

Les axes x-x et y-y ne sont pas forcément situes au même endroit.  The x-x and y-y axes are not necessarily located in the same place.
