Definitions

  • the present invention relates to hair clips, in particular used as an ornament for female hairstyle.
  • Such hair clips have been known for a long time, as described in the document FR-A-770 805, which generally comprise a first jaw actuable by a first opening lever to which it is secured according to a first intermediate connection zone, and a second jaw actuated by a second opening lever to which it is secured according to a second intermediate connection zone.
  • Articulation means connect the first and the second intermediate connection zone, to allow the respective pivoting of the first jaw and the second jaw relative to each other about a transverse articulation axis.
  • Elastic means are necessary to pivotally urge the first and second jaws relative to each other towards their tight position.
  • the elastic means comprise a spring constituted by a helical elastic metal wire wound around the transverse articulation axis, a first end of the metal wire projecting radially from the axis and coming to bear under the first opening lever, the second end of the metal wire projecting radially from the axis and coming to bear under the second opening lever.
  • a first drawback of such a structure is that it requires the use of a metal wire, while the rest of the hair clip is generally made of plastic. In use, the metal wire is likely to be corroded by humidity and the various products used in hairdressing.
  • a second drawback of this known structure results from the particular use of such pliers which, when positioned in a hairstyle, generally leave their posterior parts visible, that is to say the part constituted by the two internal faces of the opening levers, by the rear face of the articulation zone and by the elastic metallic wire. This results in a particularly unsightly effect, especially since the spring structure, made of metal wire, is clearly apparent and gives the appearance of a mechanical organ to a hair clip which should mainly constitute an object of adornment and ornament.
  • the document FR-A-1 317 575, and the document GB-A-1 013 720 in the embodiments of FIGS. 1 to 8, describe clamp structures for fixing coiled hair, in which the spring is an elastic blade U-shaped whose branches come to bear under the opening levers to separate them from each other. As the elastic blade tends to separate the two clamp parts from one another, it is then necessary to provide hinge means to maintain the connection between the two clamp parts. In addition to the manufacturing and mounting difficulties which result, the elastic blade requires an oversizing of the hinge, and the elastic blade must be made of metal if a sufficient return torque is desired.
  • the problem proposed by the present invention is to design a new structure of hair clip whose spring, while ensuring the elastic return function with sufficient torque, constitutes in itself by its compact form and its appearance a decorative element.
  • the invention thus aims to avoid the use of metal parts, and on the contrary to produce the entire clamp in various plastics, the various parts of the clamp having to be able to be decorated.
  • the clip according to the invention can thus constitute a hairstyle ornament intended to remain in the hair.
  • clamp structure according to the invention must be able to be produced at low cost, and in particular must be able to be assembled quickly and easily.
  • the elastic means comprise a single spring piece, disposed in an axial position centered on the jaws, and passing through respective passage openings made in the opening levers and having appropriate dimensions.
  • the elastic means comprise two spring parts offset respectively on either side of the longitudinal axis of the part, away from the opening levers.
  • the spring piece is advantageously made of a polyamide or a polyacetal having good deformation capacity and which can be decorated.
  • a hair clip according to the present invention comprises a first jaw 1 which can be actuated by a first opening lever 2 to which it is secured according to a first intermediate connection zone 3, and a second jaw 4 which can be actuated by a second opening lever 5 to which it is secured by a second intermediate connection zone 6.
  • the first and second jaws have a general crescent moon shape, developing transversely relative to the anteroposterior direction II-II of the forceps or general direction of the opening levers 2 and 5
  • the jaws 1 and 4 comprise, in the vicinity of their edges opposite the opening levers 2 and 5, a series of teeth 70 interlocking with one another.
  • Hinge means connect the first intermediate connection zone 3 and the second intermediate connection zone 6, to allow the respective jaws 1 and the second jaws 4 to pivot relative to each other about an axis. transverse joint II, between a spread position and a tight position.
  • the spring piece 7 is arranged in an axial position centered on the jaws 1 and 4, and passes through respective passage openings 8 and 9 formed in the opening levers 2 and 5 .
  • the spring piece 7 made of elastic material, has a general U-shaped profile, with a first longitudinal branch 10 generally flat and a second longitudinal branch 11 generally flat.
  • the two branches 10 and 11 are generally parallel and facing each other, connected to each other by a connecting branch 12.
  • the longitudinal branches 10 and 11 are convergent at rest , so that, when the spring piece is arranged on the clamp, the longitudinal branches 10 and 11 are found substantially parallel to each other and have an elastic pre-stress ensuring a thrust of the jaws against one other.
  • the first longitudinal branch 10 comprises, in the vicinity of its free end, a first hooking portion 13 developing in the direction of the second longitudinal branch 11.
  • the second longitudinal branch 11 comprises, in the vicinity of its free end, a second attachment part 14 developing in the direction of the first longitudinal branch 10.
  • a spring piece 7 with a generally rectangular section, relatively flat and wide.
  • the increase in width of the spring piece 7 makes it possible to increase the elastic return torque that it produces on the jaws 1 and 4, without increasing the size of the spring piece 7 beyond the external faces 16, 17 of the bit.
  • the spring piece 7 can have a constant width.
  • the spring piece 7 may have variations in width, for example lateral notches such as the notch 15, creating preferential fold zones.
  • the spring piece 7 is capable of deforming preferably in the vicinity of the ends of attachment of the longitudinal branches 10 and 11 with the connecting branch 12; the longitudinal branches 10 and 11 as well as the connecting branch 12, of greater width, tend to have smaller deformations.
  • the spring piece 7 is adapted on the jaws 1 and 4 to press them towards each other.
  • the first longitudinal branch 10 of the spring piece 7 bears on the outer face 16 of the first jaw 1 through its free end zone.
  • the second longitudinal branch 11 is supported on the outer face 17 of the second jaw 4 by its free end zone.
  • the connecting branch 12 of the spring piece 7 is oriented rearward in the direction of development of the opening levers 2 and 5.
  • the outer face 16 of the first jaw 1 comprises a first perforation 18 arranged and shaped to receive at low clearance the first attachment part 13 of the spring piece.
  • the outer face 17 of the second jaw 4 comprises a second cut-out 19 arranged and shaped to receive the second attachment part 14 of the spring piece with little play.
  • the connecting branch 12 has a length such that, when the clamp is in the clamped position, the two jaws 1 and 4 being in abutment against each other, each of the longitudinal branches 10 and 11 of the spring piece 7 is generally parallel to the outer surface of the respective jaws 1 or 4 of pliers and is pressed against or in the immediate vicinity of said corresponding outer surface 16 or 17.
  • the pliers thus have a particularly reduced bulk and a pleasant and aesthetic appearance.
  • the spring piece 7 must be made of a material having a good capacity for elastic deformation.
  • a material having a good capacity for elastic deformation can for example advantageously use a polyamide such as the product designated by the GRILAMID brand, distributed by the French company EMS, or a polyacetal such as the products distributed under the brands HOFTAFORM or ACETAL 10 T by the Italian company TAROPLAST.
  • a spring piece 7 can itself be decorated.
  • each passage lumen 8 and 9 must have a width greater than the width of the longitudinal branches 10 and 11 and of the connecting branch 12 of spring piece 7, and a length sufficient to allow passage and free longitudinal movement of the connecting branch 12 of spring piece during the opening operation of the hair clip.
  • connection branch 12 of the spring part 7 is relatively close to the hinge zone, when the clamp is in the closed position.
  • the connecting branch 12 is further from the hinge zone, and approaches the corresponding posterior ends of the slots 8 and 9.
  • the hair clip according to the invention comprises two spring parts 107 and 207, of structures similar to part 7 of the previous embodiment.
  • the spring parts 107 and 207 are offset respectively on either side of the longitudinal axis II-II of the clamp, and are located away from the opening levers such as the lever 2. In this case, there it is not necessary to provide a passage light in the levers.
  • the articulation means can a priori be produced by any known means.
  • the articulation means can advantageously be produced as shown in the figures, by engaging male and female parts which simply come to bear against one another under the action of the spring piece 7.
  • a female engaging part 20 provided on the inner face of the second intermediate connecting zone 6 is provided, and a male engaging part 21 formed on the inner face of the first intermediate connecting zone 3.
  • the rear face of the articulation means can advantageously be hidden by the spring piece 7.
  • the piece spring 7 in the embodiment of FIGS. 1 to 6, comprising a single spring piece 7, it is advantageously possible to give the piece spring 7 a width substantially equal to the length of the male 21 and female 20 hinge parts.
  • the hinge means are substantially covered by the connection branch 12 of the spring piece 7.
  • the embodiment of Figure 7 comprising two spring pieces 107 and 207, two parts of coaxial hinge covered respectively by the spring piece 107 and by the spring piece 207.
  • the rear face of the clamp which is usually visible when the clamp is arranged in a hair, has a pleasant appearance due to the fact that no helical metal spring and no means of articulation is apparent .
  • the spring piece 7 fulfills both the function of an elastic return means for the jaws, and the function of a cover to conceal the articulation means.
