Hair curler, more especially for a permanent wave, comprising a roller (1) on which the hair to be treated is to be rolled and locking means associated with said roller for maintaining same in position on the head of a user, said locking means comprising two clips (2) shaped as opened washers gripping round said roller, especially on ends thereof, characterized in that said locking means are adapted as a single locking device having a generally cylindrical of revolution shape, the both end faces of which are respectively constituted of said both clips (2) which are joined to each other with distance-pieces (10) circumferentially distributed and spaced from each other along the outer periphery (3) of said clips, the ends (3a) of clips being however devoid of distancepieces, that the radial size of clips is greater than the thickness of the hair to be rolled on the roller so that in use the hair is not contacted by distancepieces, and that, for at least one end distancepiece (23), the surface (24) thereof to be contacted by hair (25) is convex and curved to the curve of the clips ends, the length of said surface being such that in use it extends substantially up to the head (5) of the user.

Description

Improvements to hair curlers, especially for perms 1 La

  present invention relates to improvements made to curlers, in particular, but not exclusively,

to curlers for perms.

  Most curlers known at the present time, whatever the types thereof, include blocking means - intended to cooperate with a roller on which the hair to be treated is wound to maintain said roller on the head of a user. - who in position

  are in contact with the hair: they

  visible marks prevail over the hair

  desirable - and they can even lead to breakage of

  hair at the contact locations.

  In other types of curlers, the means of blocking

  ge consist of a pin inserted diametrically into the roller. However, the positioning of the pin is not simple and rapid; thereby,

  hairdressing professionals hardly use them.

  The object of the invention is essentially to remedy the drawbacks presented by current curlers and to propose curlers which better meet the various requirements of practice, and in particular in which the

  blocking means are not in contact with the sleeves

  want and which remain of a simple and fast handling all

  being inexpensive and easy to manufacture.

  For these purposes, in a curler, especially permanent fear

  te, comprising: - a roller on which the hair to be treated must be wound, - and blocking means intended to be associated with the aforesaid roller for holding it in place on the head of a user, provision is made, in accordance with invention, that the means of

  locking include two pliers in the form of washers or-

  green on at most 270, said grippers having a peripheral annular part radially distant from a central void in which is intended to be embossed an axial zone of end of the roller (first axial zone), said grippers, in functional position, then enclosing elastically the roller respectively on either side of the central axial zone thereof on which the hair to be treated must be wound, so that the free ends of the annular peripheral parts of the pliers are in abutment against the head of

  the user to prevent the curler from rolling.

  Thanks to this arrangement, the two clips are located on the roller outside the hair winding zone: no part of these clips is therefore in contact with the hair wound on the roller and there thus exists - no risk of unwanted hair deformation. In addition, the positioning of the clamps on the roller is quick and easy, and the blocking thus obtained,

  by pressing pliers on the head, is ser and effective.

  In an advantageous embodiment, it is provided that, in each clamp, the peripheral annular part is elastically deformable, and it is also provided

  a plurality of converging spokes from said part

  curved peripheral link along these spokes

  such that their free ends delimit the central vacuum

aforementioned tral.

  In order to increase the ease of positioning the clamps on the roller, it is preferable that, on each clamp, the regions close to the free ends of the

  peripheral annular part are devoid of spokes.

  In order to avoid multiple manipulations9 it is provided, in a preferred embodiment, that the two clamps

  are joined together by spacers, said en-

  trestles connecting to the clamps in the vicinity of the outer edge of the anrlair-es parts being either rectilinear or curved towards the outside-ur and leme length being such that, positicn mounting mounting blocking means

  on the roller, the grippers occupy the position above

  on both sides of the axial zone of the roller

  on which the hair is rolled up. -

  In the particular case of lukewarm perms, ef-

  made with a heating pliers enclosing the

  hair coiled on the roller, it is expected that the

  toises are such, in particular as regards their number and their distribution along the annular parts of the pins

  these, that they release a free space by which a pin-

  this heater can 8tre introduced and set up on

  hair rolled up on the curler roller.

  According to yet another provision which is used from

  preferably with one and / or the other of the pre-

  can be arranged so that each clamp is mutually

  nie of an arm integral with the annular part and sensi-

  tangentially tangent thereto, said arm extending sensi-

  in the same plane as the clamp. Thanks to this agent-

  cement, once the blocking means put in place on

  the rollers, the arms are supported on a curler

  sin, which helps to ensure the blocking of each bi-

  curled especially in the case where the curlers are arranged in regions of the head having a pronounced curvature, and where the two pliers may not be able to bear

on the head simultaneously.

  Preferably, in one and / or the other of the preceding cases

  teeth, axial stop means are provided for axially positioning each gripper on the roller and for

prevent it from sliding axially.

  In a first embodiment, the first

  axial zones of the roller have a relief and the

  gripper regions intended to cooperate with said pre-

  the axial zones of the roller have a relief of

  complementary form of the previous one, and then, advantageous

  ment, .said first axial zones of the roller poss-

  tooth a diameter greater than the diameter of the axial zone

  central on which the hair must be coiled.

  In another embodiment, the first axial zones have a diameter less than the diameter of the central zone, and the axial stop means are

  formed by the connection zones of the first zo-

  nes axial and of the central zone, respectively # and then, advantageously, the free ends of the roller are swollen in the shape of a button and determine with the central axial zone of the respective annular grooves,

  whose bottoms constitute the first axial zones.

  It is also possible to provide that the roller also comprises second axial zones situated respectively

  between the above first axial zones and the central zone

  trale, the second axial zones being arranged to sup-

  wear a rollable device for protecting part of the hair to be treated, such as for example the device

  protection described in patent application FR 78 22017.

  In this case, it is advantageous that the second zones

  are frustoconical with tapered faces facing the extremi

  free tees. durouleau, so that flows of the product to perm are separated from the coiled hair

  on the central axial zone of the roller.

  The invention will be better understood on reading the

  description which follows of some of its embodiments

  tion given for illustrative purposes only, without any ca-

  limiting character.-In this description, reference is made

  numeric to designate identical items.

  Referring first to Figure 1, a bigou-

  di arranged in accordance with the invention comprises a roller 1 and two clamps 2 (only one being visible in FIG. 1) able to grip said roller respectively in the

end zones thereof.

  Each clamp 2 has a peripheral annular part

  rique 3 extending only over a portion of a circle, preferably about 2700 or three quarters of a circle, and formed in the form of a band having a certain elasticity. From this peripheral annular part 3 extend- radial arms 4 directed inwards and having a length substantially less than the radius of the annular part 3 so as to determine, between their

  free ends, a circular empty space having a diameter

  meter slightly smaller than the diameter of the end zones

from the roller 1.

  Preferably, the free ends 3a of the annular part 3 are devoid of spokes, and the last spokes

  4a are located behind said ends in order to avoid

  ter any unnecessary contact with the hair.

  Thanks to this arrangement, each clamp 2 snaps onto the roller 1 by elastic deformation of the annular part 3 and bears on the head 5 of the user by the free ends 3a of the annular part 3. In

  because of the distance between the ends 3a, the pins

  these build on the head stably and the whole

can't turn.

  In addition, the fact that each clamp 2 grips close

  the roller 1 between the free ends of the spokes 4, the roller 1 is prevented from turning relative to the clips 2. It is therefore always ensured that the hair coiled

  on roll 1 will not be able to take place.

  As best seen in Figure 27 the clamps 2 are mounted on the axial end regions 6 of the roller 1, on each side of a central axial region 7 of the roller on which the hair to be treated is to be wound. As shown in Figure 2, the roller 1 is arranged so that the end zones 6 have a diameter greater than the central zone 7. In addition, so that each clamp 2 is stably supported on the zones ends 6 which are cylindrical

  of revolution, said clamps have a width nota-

  ble, appreciably larger than that of the pliers

presented in the other figures.

  To prevent the clamps 2 from sliding laterally (that is to say axially) on the roller, provision is made for axial abutment means comprising an annular bead 8 projecting from each end zone 6 and a recess 9, of complementary shape that of the bead 8, hollowed out at the end of each spoke, all of these recesses

  forming a discontinuous annular gutter suitable for alem-

kick on the bead 8.

  As shown in Figure 2, in this first embodiment, the two clamps 2 are separate from each other and must therefore give rise to separate manipulations. In the second embodiment of Figure 3, the two clamps 2 are secured to each other by

  spacers 10 which are distributed circumferentially-

  along the annular parts 3, the length of which corresponds to the spacing of the clamps 2 in their position

mounting on the roller 1.

  The spacers 10 can be straight as

  presented in FIGS. 3 and 4, or else be curved with a convexity turned towards the outside in order to release a larger free space around the central zone 7 of the roller, which can then receive a thickness of

more coiled hair.

  We can foresee that the spacing, the position and the number of spacers 10 coincide with those of spokes 4,

  without, however, being an obligation.

  In particular, when the curler is intended for

  perform a warm perm using a pair of hot tongs

  spacer, spacers are only pre-seated towards the

  end regions 3a of the annular parts 3 for disengaging

  manage a passage in the central region to introduce the heating clip and place it on the hair

wound on the roll 1.

  The means of axial stop of the clamps 2 on the wheel

  Water 1 can be of the same type as those indicated above.

  as for the first embodiment shown in

  Figure 2; however, by way of example, we have represented

  tee in Figure 3 a variant of such stop means. The roller 1 has, in its end zones 6, necks 11 of sufficient width and depth so that the

  free extremities of spokes 4 can engage in it.

  In FIG. 4, yet another variation is shown.

  laughing means of axial stop of the clamps 2. The zones

  ends 6 of the roller are here provided with a simple head

  tone 12 on which the corresponding clamp fits

  you. Obviously, in the embodiments of FIGS. 3 and 4, the length of spokes 4 must be adapted in such a way that said spokes bear on the bottom of the

groove 11 or on nipple 12.

  In FIG. 4, the roller 13 is intended to be used

  read more particularly in combination with a device

  protective hair tif 14 and with a clamp system

like the one in figure 3.

  The roller 13 is therefore shaped at its ends

  me the roller 1 of figure 3, that is to say with a groove

  ge He; however, its central zone 15 is cylindrical of revolution and is surrounded by two zones 16 of a diameter

  slightly higher and able to receive the protective device

14.

  Said protective device 14 is intended to protect

  from product action to permanent parts of the che-

  want not located near the root, and it consists

  laying a rigid or semi-rigid gutter 17, a flexible waterproof sheet 18 having properties

  adhesive, and a strip 19 of absorbent material, in particular

  foam. An example of such a protective device

  is described in patent application FR 78 22017.

  At the outer end of the zones 16, that is to say at the edge of the grooves 11, is provided an annular bead of diameter greater than that of the zones 16 and serving

  axial stop for the protective device 14.

  We start by winding the end of the hair on

  the central zone 15, then the device is interposed

  guardian 14 in the manner specified in the patent application

  vet FR 78 22017 so as to leave free the part of the hair close to the roots. The protective device then rests on the zones 16. Next, the clamp device of FIG. 3 is put in place which is fitted onto

  the roller without touching the visible part of the hair.

  Preferably, the zones 16 are frustoconical to conical

  cities facing outwards, so that

  lements of product to permanent be rejected towards the ex-

  lower and not brought back towards the hair.

  In Figure 6, there is shown yet another embodiment in which the clamps 2 (whether they are

  independent as in the embodiment of the fi

  gure 2 or that they are linked by spacers as in the embodiment of FIG. 3) are each provided with an arm 21 linked to the annular part 3 in the middle part thereof and disposed tangentially thereto this. The length of these arms can be of the order of 1.5 to 2 times the radius of the annular part 3, such

  so that when the curlers are arranged parallel-

  lying one after the other, the arms of a curler

  come to lean on the neighboring curler. The arms 21 con-

  thus contribute to blocking the curlers even when the ends 3a are not in contact with the head and can no longer prevent the curler from rolling (for example

  in the head region with pronounced curvature

  cée). In Figure 7, there is shown a variant of the embodiment of Figure 6 in which the clamps 2

  are surmounted by a hoop 22 in which can be engaged

  gée the free end of the arm 21 neighboring curler curler.

  The arch 22 can extend above the arm 21 (as shown in FIG. 7), or on the contrary it can be directly integral with the annular part 3 and support

  ter itself, at its upper part, the arm 21 corresponds to

  laying. Of course, in the case of locking means of the kind of those shown in Figures 3 and 4, that is to say

  when they include two clamps 2 joined by

  trestles 10, the arch 22 extends from one clamp to another

  parallel to the spacers 10, which simplifies the

  conversion of the ends of the arms 21.

  Such an embodiment offers the advantage of being

  see making montages "in the air" useful for some

  hairstyles, that is to say fixtures in which the bi-

  curls (except the first) do not rest on the head of the user and hang at the end of the hair, the arms 21 engaged in the arches 22 pocketing the curlers

unfold.

  Finally, FIG. 8 represents yet another mode of

  realization of blocking means of the kind of those of the

  Figures 3 and 4, i.e. made up of two clamps 2

joined by spacers 10.

  In this particular embodiment, provision is made

  that one of the last spacers or end spacer

  mity 23 (the one on the right in FIG. 8) has a particular shape, namely that its face 24 facing inwards is convex and that its width is large enough so that, once the assembly is placed in functional position on a head , it extends significantly

  Up to the head. As shown in Figure 8, this en-

  particular tretoise can have the shape of a half

  cylinder of revolution or the like.

  The advantage of such an arrangement is that the part of the

  hair 25 between the root and the curler is ap-

  folded against the surface 24 and shaped (folded) by this surface (as shown in dashes in FIG. 8), while in the absence of such a surface this

  Even part of the hair would remain wrong.

  As goes without saying and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more especially envisaged; she embraces it, at

otherwise, all variants.

  The curlers arranged in accordance with the invention are

  simple and inexpensive to manufacture, can be

  made from cheap materials (molded plastic),

  and avoid the drawbacks of curlers used up to now

than now.
