Description

[0023] Hereinafter, the invention is explained with reference to exemplary embodiments illustrated in the drawings.

[0024] FIG. 1 depicts a side view of the device for shaping and styling the hairs, in accordance with the invention;

[0025] FIG. 2 is a view of the device along the section AA′ shown in FIG. 1;

[0026] FIG. 3 is a top view of the device for hair-styling, in accordance with the invention;

[0027] FIG. 4 depicts a perspective view of the device for hair-styling according to the invention; and

[0028] FIG. 5 is another perspective view of the device for hair-styling in accordance with the invention.

[0029] First, the essential elements of the invention would be explained, with respect to the different views of the device 1 for hair-styling in accordance with the invention depicted in the figures. This device 1 includes a base body 10, as shown. An attachment surface 20 and a shaft 30 are arranged adjacent to each other, or engaging with each other, in the longitudinal direction 11 of the base body 10. Altogether, the device resembles a bell-shaped structure. The shaft 30 includes a concave-shaped longitudinal section 31, as well as an adjoining convex-shaped longitudinal section 35, which is connected to the concave-shaped longitudinal section 31 via a turning point 34 (i.e., point of inflexion).

[0030] It is apparent that the base body 10 has an essentially rotationally symmetric design, with the rotational axis extending parallel to the longitudinal length 1′. The concave-shaped longitudinal section 31 has a concavity 32, which has its deepest point 33 approximately lying at the center of the shaft 30.

[0031] Due to the rotationally symmetrical design of the base body 10, it is self-evident that the deepest point 33 as well as the turning point (point of inflexion) 34 mentioned herein, are not to be understood as geometric points, but, in the cross-section, circumferentially around the shaft 30, these points define circles.

[0032] The attachment surface 20, which delimits base body 10 at one end, also has a concavely extending surface 21, as particularly seen in FIG. 2. The concavely extending surface 21 adapts the device 1 to the curvature of the head of a person to be hair-dressed.

[0033] Longitudinal grooves 40 are provided on the surface of the shaft 30, which are arranged circumferentially around the shaft. In their longitudinal direction, these grooves 40 extend parallel to the longitudinal direction 11, or to the axis of rotation AA′. As seen, the grooves 40 extend along a direction towards the attachment surface 20, as well as towards the free end 60 positioned opposite to the attachment surface 20.

[0034] Due to the circumferential distribution of the longitudinal grooves 40 on the shaft 30, ribs 50 are created between these grooves 50, whose maximum radial extensions form the surface of the shaft 30. As can be seen in FIG. 3, the ribs extend both in the region of the shaft 30 facing the attachment surface 20, as well as the region near the free end 60.

[0035] For reducing the stress on the hairs draped on the hair-styling device 1, and to prevent the visibility of the device in accordance with the invention under the hairs, the longitudinal grooves 40 are provided with roundings 41 on their side regions. These roundings 41, each has a radius 42, designed such that it creates a very smooth and seamless transition between the grooves 40 and the ribs 50.

[0036] The ratio of the longitudinal length L of the hair-styling device 1 according to the invention, to its minimum diameter D.sub.min, as measured in the region of concavity 32 of its concave-shaped longitudinal section 32, and particularly here at the deepest point 32, is preferably set in such a manner that a push-effect is imparted to the ponytail, which avoids the risk that regions of the device 1 protruding between the draped hairs become visibly recognizable.

[0037] Analogously, the depth T.sub.r of the longitudinal grooves is designed with respect to the minimum diameter D.sub.min. Similarly, a ratio is accordingly established between the maximum diameter of the shaft 30 D.sub.max, measured at the region of maximum outward radial extension of its convex-shaped longitudinal section 35, to the minimum diameter D.sub.min in the region of concavity 32 of the concave-shaped longitudinal section 31.
