Device for forming hair

Abstract

A hair styling device has two arms 2, 3. Each arm 2, 3 has a styling part 5, 6, which cooperates with the styling part 5, 6 on the other arm 2, 3 for the hair styling operation. At least one styling part 5, 6 is designed for heating hair inserted into the hair styling gap 9 located between the styling parts 5, 6. A pressure measuring device D is included in one of the two arms. The pressure measuring device D detects the pressure, or a value representing this pressure, exerted on the hair 17 between the styling parts ( 5, 6 ) when the hair styling gap 9 is closed. The hair styling device 1 also has a display device 19 for displaying the pressure or pressure value thus detected.

1 . A hair styling device comprising:
 a first arm;   a second arm;   the first and second arms connected at a pivot point;   the first arm having a first styling part;   the second arm having a second styling part;   the first and second styling parts cooperating for the hair styling operation;   a hair styling gap located between the first and second styling parts;   at least one styling part capable of heating hair inserted into the hair styling gap;   a pressure measuring device located in either the first or second arm; and   a display device for displaying the pressure or pressure value detected.   
   
   
       2 . The hair styling device according to  claim 1 , wherein the pressure measuring device is a pressure sensor on which a styling part is supported. 
   
   
       3 . The hair styling device according to one of  claim 1  or  2 , wherein the output signal of the pressure measuring device is sent to an evaluation unit which triggers the display device. 
   
   
       4 . The hair styling device according to  claim 3 , wherein the evaluation unit comprises a comparator for comparing the measurement signal of the pressure measurement device with an adjustable threshold value. 
   
   
       5 . The hair styling device according to  claim 3 , wherein an actuator generating a tactile signal for a person operating the hair styling device is provided as the display device. 
   
   
       6 . The hair styling device according to  claim 2  further comprising:
 a supporting body attached to the back side of the styling part;   the supporting body resting on a pressure measurement strip;   the pressure measurement strip resting on an abutment; and wherein the styling part is mounted on the supporting body so that the styling part is rockable.   
   
   
       7 . The hair styling device according to  claim 6 , wherein the supporting body is located approximately the middle of the styling part in the longitudinal direction of the arm. 
   
   
       8 . The hair styling device according to  claim 6 , wherein the supporting body is dome shaped so that a seesawing action of the styling part in different directions is possible. 
   
   
       9 . The hair styling device according to  claim 6 , wherein the styling part has guide protrusions integrally molded on the side for limiting the pivoting movements in at least one direction. 
   
   
       10 . The hair styling device according to  claims 6 , wherein the hair styling parts are styling plates for straightening hair.
