Description

       

  Appareil électrique portatif de coiffure pouvant être utilisé pour lisser ou friser les cheveux.

  
La présente invention concerne un appareil électrique portatif de coiffure et vise la création d'un appareil de conception simple pouvant être utilisé :
a) soit comme friseur en vue de produire des ondulations dans la chevelure b) soit pour lisser les cheveux en permettant ainsi si nécessaire de les défriser.

  
En vue de la réalisation de ce but, l'appareil est caractérisé en ordre principal en ce qu'il comprend deux blocs chauffants ayant chacun une face munie d'ondula-tions et une face opposée lisse et en ce que l'on prévoit des moyens par lesquels soit les deux faces ondulées soit les deux faces lisses peuvent être mises en contact.

  
Dans la réalisation pratique de l'invention, l'appareil comporte une poignée recevant deux branches dont chacune porte extérieurement un bloc chauffant, une branche étant montée fixe et l'autre branche étant montée à pivotement par rapport à la poignée et chaque bloc chauffant étant monté rotatif sur la branche correspondante.

  
D'autres caractéristiques de l'invention ressortiront de la description ci-après avec référence

  
aux dessins annexés dans lesquels :
La figure 1 est une vue en élévation latérale de l'appareil friseur-défriseur. La figure 2 est une vue en coupe de cet appareil.

  
Les figures 3A et 3B sont des vues en élévation frontale montrant les deux positions de travail des blocs chauffants de l'appareil et la figure 4 est une vue en coupe d'un bloc chauffant.

  
Dans ces différentes figures les mêmes notations de référence désignent les mêmes éléments.

  
L'appareil comprend une poignée 1 creuse habituellement moulée en un matériau synthétique dans laquelle sont introduites des branches 2, 3 servant chacune de support à l'extérieur du manche à un bloc chauffant 4, 5.

  
La branche 2 du bloc chauffant 4 est montée fixe et est rendue solidaire de la poignée 1 par un goujon 6 ; la branche 3 du bloc chauffant 5 est montée

  
de manière à pivoter autour d'un axe 7 traversant la poignée 1 ; afin de rendre possible ce pivotement, la paroi de la poignée est munie, du côté se trouvant vis-à-vis des blocs chauffants 4, 5, d'une fente ou d'une rainure 8 (figure 2).

  
Un ressort à lame 9 est fixé sur la branche 3 et prend appui sur la branche 2 de manière à maintenir normalement les branches 2, 3 en position écartée
(position représentée à la figure 2).

  
Sur un pivot 11 porté par la poignée 1 est monté de manière à pivoter un levier ou une manette

  
10 qui est conformé de manière à pouvoir agir sur la branche 3 afin de provoquer le pivotement de celle-ci.

  
Lorsqu'on fait pivoter le levier 10 dans le

  
 <EMI ID=1.1> 

  
 <EMI ID=2.1> 

  
branche 3 est ramenée par le ressort 9 dans la position écartée.

  
Ainsi que le représente la figure 4,

  
les blocs chauffants 4, 5 sont montés de manière à pouvoir tourner autour de la branche correspondante 2 ou 3.

  
Chaque branche 2, 3 comporte deux encoches
12 de localisation opposées diamétralement dans lesquelles peut venir s'engager alternativement une bille 14 située dans un logement 13 et soumise à l'action d'un ressort 15 et d'une vis 15<1> exerçant une pression vers la branche.

  
Une caractéristique importante est que chaque bloc chauffant (figures 3A-3B) comprend une face lisse (références 16-17) et une face opposée munie d'ondu-lations (références 18-19). Les ondulations des deux faces sont complémentaires entre elles.

  
Ces ondulations ont habituellement une forme arrondie.

  
Le passage d'une position à l'autre a lieu en faisant pivoter à la main le bloc chauffant de 180[deg.].

  
 <EMI ID=3.1> 

  
dégagée de l'encoche 12 où elle se trouve tandis que

  
 <EMI ID=4.1> 

  
et celle-ci y pénètre en fixant le bloc chauffant dans la position choisie.

  
En appliquant un couple de rotation suffi-

  
 <EMI ID=5.1> 

  
15 et on peut ainsi libérer le bloc chauffant 4 ou 5 qui peut alors pivoter.

  
L'alimentation en courant a lieu par

  
un câble 20 qui aboutit à un connecteur 21 d'où partent deux ramifications 22, 23 dont l'une alimente le bloc chauffant 4 tandis que l'autre alimente le bloc chauffant 5.

  
Ainsi que cela ressort de la figure 4, chaque branche est constituée par un tube métallique

  
2<1>, 31 qui comporte à son extrémité un bloc chauffant désigné dans son ensemble par la référence 24.

  
Les fils 22, 23 sont recouverts d'une couche de teflon laquelle forme joint en 25 dans le bloc chauffant.

  
En pratique ce bloc comprend par exemple une résistance cylindrique auto-régulatrice (220 V - 35 W).



  Portable electric hair styling device that can be used to straighten or curl hair.

  
The present invention relates to a portable electric hairdressing device and aims to create a device of simple design that can be used:
a) either as a curler in order to produce waves in the hair b) or to straighten the hair, thus allowing it to be straightened if necessary.

  
With a view to achieving this goal, the apparatus is characterized in the main order in that it comprises two heating blocks each having a face provided with undula-tions and a smooth opposite face and in that there are provided means by which either the two corrugated faces or the two smooth faces can be brought into contact.

  
In the practical embodiment of the invention, the apparatus comprises a handle receiving two branches, each of which carries a heating block on the outside, one branch being fixedly mounted and the other branch being mounted to pivot relative to the handle and each heating block being rotatably mounted on the corresponding branch.

  
Other characteristics of the invention will emerge from the description below with reference

  
to the accompanying drawings in which:
Figure 1 is a side elevational view of the crimper-straightener apparatus. Figure 2 is a sectional view of this device.

  
Figures 3A and 3B are front elevational views showing the two working positions of the heater blocks of the apparatus and Figure 4 is a sectional view of a heater block.

  
In these different figures the same reference notations designate the same elements.

  
The apparatus comprises a hollow handle 1 usually molded from a synthetic material into which are introduced branches 2, 3 each serving as a support outside the handle for a heating block 4, 5.

  
The branch 2 of the heating unit 4 is mounted fixed and is made integral with the handle 1 by a stud 6; branch 3 of heating block 5 is fitted

  
so as to pivot about an axis 7 passing through the handle 1; in order to make this pivoting possible, the wall of the handle is provided, on the side facing the heating blocks 4, 5, with a slot or a groove 8 (FIG. 2).

  
A leaf spring 9 is fixed on the branch 3 and bears on the branch 2 so as to normally maintain the branches 2, 3 in the separated position
(position shown in Figure 2).

  
On a pivot 11 carried by the handle 1 is mounted so as to pivot a lever or a lever

  
10 which is shaped so as to be able to act on the branch 3 in order to cause the latter to pivot.

  
When the lever 10 is rotated in the

  
 <EMI ID = 1.1>

  
 <EMI ID = 2.1>

  
branch 3 is returned by the spring 9 to the separated position.

  
As shown in Figure 4,

  
the heating blocks 4, 5 are mounted so as to be able to turn around the corresponding branch 2 or 3.

  
Each branch 2, 3 has two notches
12 of diametrically opposed location in which a ball 14 located in a housing 13 and subjected to the action of a spring 15 and a screw 15 <1> exerting pressure towards the branch can be engaged alternately.

  
An important feature is that each heating block (Figures 3A-3B) comprises a smooth face (references 16-17) and an opposite face provided with corrugations (references 18-19). The undulations of the two faces are complementary to each other.

  
These waves usually have a rounded shape.

  
Switching from one position to the other is done by rotating the heating block by hand by 180 [deg.].

  
 <EMI ID = 3.1>

  
released from notch 12 where it is located while

  
 <EMI ID = 4.1>

  
and the latter enters it by fixing the heating block in the chosen position.

  
By applying sufficient torque

  
 <EMI ID = 5.1>

  
15 and it is thus possible to release the heating block 4 or 5 which can then pivot.

  
Power is supplied by

  
a cable 20 which ends in a connector 21 from which two branches 22, 23 leave, one of which supplies the heating block 4 while the other supplies the heating block 5.

  
As emerges from Figure 4, each branch is formed by a metal tube

  
2 <1>, 31 which comprises at its end a heating block designated as a whole by the reference 24.

  
The wires 22, 23 are covered with a layer of Teflon which forms a joint at 25 in the heating block.

  
In practice, this unit comprises for example a self-regulating cylindrical resistor (220 V - 35 W).

Claims

Experience has shown that a satisfactory result is obtained by an electronically controlled dual high-isolation heater with compensation <EMI ID = 6.1>

The handling of the device is extremely simple.

If you want to curl hair, turn each of the heating blocks 4, 5 around

their branches 2, 3 so that their respective wavy faces are facing each other; the device is switched on; we place a lock of hair

to curl between the two heating blocks; we act on

lever 10, causing it to be tightened so that the

heating blocks take the position shown on the

Figure 3A and are maintained for the time required to curl the hair. The crimping being obtained, the lever 10 is released and the two heating biocs are thus separated.

by releasing frizzy hair; the operation can be repeated with the next bit.

If you want to straighten or straighten hair, you operate as described above, except that you put

the two heating blocks in the position where their

smooth faces face each other so that

the hair is pinched between two heating blocks

placed as shown in Figure 3B.

1. Portable electric hairdressing device which can be used to straighten or curl the hair, characterized in that it comprises two heating blocks each having a face provided with undulations and an opposite smooth face and in that means are provided by which either the two corrugated faces or the two smooth faces can be brought into contact.

2. Apparatus according to claim 1, characterized in that it comprises a handle (1) receiving two branches (2, 3) each of which carries on the outside.

a heating block (4, respectively 5), the branch (2) being mounted fixed and the branch (3) being mounted to pivot relative to the comb (1) and each heating block being rotatably mounted on the corresponding branch so that either the corrugated faces (18, respectively 19), or the smooth faces (16, respectively 17) can be brought into contact with one another.

3. Apparatus according to the claims

1 and 2, characterized in that it comprises a lever or
