Definitions

• the present invention relates to a hair treatment apparatus which is intended to perform a specific shaping, including smoothing, of a person's hair, and which can also be used with an apparatus generally designed for the treatment of hair.

• the generally known methods for treating the hair for shaping generally use hot air blown by a hair dryer or a local application of heat and / or steam from a curling device and / or to smooth.
• the devices for smoothing the hair type straighteners generally comprise two heated articulating jaws that sandwich a lock of hair and form it by applying heat.
• the hot plates of these devices, even while being coated with ceramic material, are likely, in the long term, to damage the hair due to their high operating temperature.

• the moving comb is set in motion by a mechanism connected to a user-drawn cable. In operation, the combs are inserted in the open position in the hair and then the closing mechanism of the combs is actuated, which thus retain the locks of hair between their teeth. The locks thus seized are pulled upwards and dried in position by the flow of air blown by the hair dryer.
• Such a device ensures, of course, drying the hair in the stretched position and at a lower temperature, but at risk to exert a strong traction on the hair, traction also exerted by means of a cable external to the device which can be inconvenient in operation Moreover, when wicks of different thicknesses penetrate between neighboring teeth, the forces exerted by the teeth on the locks are not uniform and, as a result, only the thickest lock is seized, the thinner neighboring locks may escape to the outside of the combs. This results in a non-uniform, laborious and time-consuming treatment. In addition, proposing only drying in the stretched position of the hair, this document does not address the problem of adjusting the clamping force of the combs.
• This document also describes a device for disengaging and adjusting the clamping pressure of the smoothing blades by rotating a small knurled knob accessible from the side of the device.
