Abstract

A hairstyling device for curling hair, includes a housing which includes a rolling chamber, an introduction slot which extends over the length of the housing and which opens into the rolling chamber, and an extraction opening arranged on a side end of the housing onto which the rolling chamber opens. The device includes a mandrel which extends into the rolling chamber, and a roller arranged in the rolling chamber and configured to roll the strand of hair around the mandrel, during rotation thereof. The introduction slot includes two walls which extend longitudinally and which cross the thickness of the housing, the side walls including a guiding system configured to promote the penetration of the strand of hair into the rolling chamber.

First claim

The invention claimed is:

1. Hair styling appliance for curling a strand of hair, comprising:
a housing which comprises a winding chamber having a shape of revolution along an axis, an insertion slot which extends along a length of the housing in a direction of the axis and which leads to the winding chamber, and an extraction opening arranged in a lateral end of the housing to which the winding chamber leads,
a mandrel which has one fixed end fixed to the housing and a free end arranged close to the extraction opening, and which extends in the winding chamber along another axis defined in a plane passing through the axis and through the slot, and
a winder arranged in the winding chamber and rotatably mounted in at least one direction along the other axis, the winder being configured to wind the strand around the mandrel, during its rotation, wherein the insertion slot has two walls which extend longitudinally in the direction of the axis and which cross a thickness of the housing and extend along the full length of the winding chamber, the two walls configured as a guide constructed and arranged to help the strand penetrate the winding chamber.

2. The hair styling appliance according to claim 1 , wherein the two walls form between them a V.

3. The hair styling appliance according to claim 2 , wherein the slot has a longitudinal end portion, opposite a position of the extraction opening, in which the two walls are connected to each other and form an entire V in a single piece, with a bottom configured to guide the strand and let it slip during its winding around the mandrel and the winder, the longitudinal end portion being arranged upstream from the mandrel and the winder.

4. The hair styling appliance according to claim 2 , wherein the slot has a longitudinal end portion, opposite the position of the extraction opening, in which the two walls are connected to each other and form a curved bottom configured to guide the strand and let it slip during its winding around the mandrel and the winder, the longitudinal portion being arranged upstream of the mandrel and the winder.

5. The hair styling appliance according to claim 1 , wherein the two walls each have cross ribs with respect to the axis and distributed along each wall, the ribs being configured to help the strand penetrate the winding chamber.

6. The hair styling appliance according to claim 5 , wherein the ribs each have the form of a portion of a disk.

7. The hair styling appliance according to claim 5 , wherein the ribs on each wall are of variable dimensions, with a variable distribution on the wall.

8. The hair styling appliance according to claim 1 , wherein the two walls which extend longitudinally in the direction of the axis each have waves spread along the walls, the waves being configured to help the strand penetrate the winding chamber.

9. The hair styling appliance according to claim 1 , wherein the two walls are assembled removably with respect to the housing.

10. The hair styling appliance according to claim 1 , wherein the winder is hollow and has a surface of revolution along the other axis, and is arranged with a first spacing around the mandrel in the winding chamber, coaxial with the mandrel along the other axis, the winder having on its surface of revolution at least one catch configured to catch the strand in the winder's initial position, and then to rotate the strand during the rotation of the winder, the winder being configured to successively grasp the proximal end of the strand, concomitantly wind the strand around the mandrel and the winder, and then completely wind the strand around the mandrel, during its rotation.

11. The hair styling appliance according to claim 10 , further comprising a grip handle which extends longitudinally along a handle axis and which is attached to the housing on a side opposite the slot, the plane being defined by the handle axis and the axis, the other axis being inclined with respect to the handle axis according to an angle (α) such that the free end of the mandrel is farther from the grip handle than the fixed end of the mandrel.

12. The hair styling appliance according to claim 11 , wherein the angle (α) is between 50 and 80 degrees.

13. The hair styling appliance according to claim 12 , wherein the angle (α) is 70 degrees.

14. The hair styling appliance according to claim 11 , wherein the axis and the other axis are parallel to each other.

15. The hair styling appliance according to claim 14 , wherein the axis and the other axis are coincident.

16. The hair styling appliance according to claim 10 , wherein the winder has a free edge arranged on a side of the free end of the mandrel, and a notch which extends on the surface of revolution of the winder and leads to the free edge, the notch being configured to allow the strand to penetrate the first spacing between the mandrel and the winder, in an initial position of the winder.

17. The hair styling appliance according to claim 1 , further comprising a stationary finger arranged at the contour of the extraction opening, a shape of the stationary finger is configured with respect to the free end of the mandrel to prevent the rotation of the strand around the mandrel without risk of bypassing the stationary finger during the rotation of the winder, and to help release the curled strand along the mandrel.

18. Hair styling appliance for curling a strand of hair, comprising:
a housing which comprises a winding chamber having a shape of revolution along a housing axis, an insertion slot which extends along a length of the housing in a direction of the housing axis and which leads to the winding chamber, and an extraction opening arranged in a lateral end of the housing to which the winding chamber leads,
a mandrel which has one fixed end fixed to the housing and a free end arranged close to the extraction opening, and which extends in the winding chamber along a mandrel axis defined in a plane passing through the housing axis and through the slot, and
a winder arranged in the winding chamber and rotatably mounted in at least one direction along the mandrel axis, the winder being configured to wind the strand around the mandrel, during its rotation, wherein the insertion slot has two walls which extend longitudinally in the direction of the housing axis and which cross a thickness of the housing, the two walls configured as a guide constructed and arranged to help the strand penetrate the winding chamber;
a grip handle which extends longitudinally along a handle axis and which is attached to the housing on a side opposite the slot, such that the mandrel axis is inclined with respect to the handle axis according to an angle (α) between 50 and 80 degrees such that the free end of the mandrel is farther from the grip handle than the fixed end of the mandrel.
