Double-conical curls waver

The innovation relates to double-conical hair curlers. There are already numerous double-conical ones Hair curlers known> their function, however, still not completely pacified. The innovation; has The task was to look at a new constructive way of building, in which simple constructive Measures without a lot of additional effort a weight reduction and a better protection of the hair achieved will.

This object is achieved according to the invention in that the winding body has two essentially conical, towards the middle to see tapering end pieces and a substantially cylindrically shaped one in between Center piece has that one end piece has an axially outwardly projecting pin and that Change the end piece to an annular groove running transversely to the longitudinal axis with a button-like thickening on the outside in front of it The extension carries that one annular end of an elastic retaining band is suspended in the annular groove and its other annular end if necessary against its elastic restoring force the axially outwardly projecting pin can be suspended that in the central region of the winding body (based on its L; 'no; s direction) in a first

radial plane in lease of a surface line one behind the other first through openings are arranged that in the central region of the winding body in a second radial plane perpendicular to the first radial plane, but continuous with respect to the first Openings in length rieh do g staggered second has continuous openings that the edge zones of the koniseil - tapering end pieces each in each of the two radial planes has a third through opening and that the surfaces of the wound body in at least one of the two radial planes in which the first or second through openings are arranged, each has an axially parallel longitudinal groove.

It is favorable if the in the middle area of the winding body (in relation to the longitudinal direction) through openings are slit-shaped and the length of the slots in the axial direction is greater than its 3reite in the tangential direction.

Ls has proven to be useful when the Winding body of two in one of the two radial planes touching, preferably in their Inner shells forming a common cavity exists whose common contact surface is firmly connected to one another, preferably ultrasonically welded are, and if the elastic retaining strap in its middle area (based on the longitudinal

direction) essentially with an oval, preferably circular cross-section is shaped.

V. Further training and from the design of the -firing are characterized in the subclaims and are described below in connection with the figure illustrating an embodiment. All details not necessary for an understanding of the invention have been omitted.

The figure shows a partially sectioned side view of the novel double-conical hair curler. This consists of a winding body with two essentially conical end pieces 2 and 3 tapering towards the center and an essentially cylindrically shaped center piece ¹ I between them Inside, half-shells Ib and Ic _3, which form a common cavity la, are in contact with one another at ultra-high speed. One conical end piece 3 of the winding body 1 carries an axially and outwardly protruding pin 5 and the other end piece 2 has a circumferential groove 6 transversely to the longitudinal axis with a button-like protrusion 7 lying in front of it.

in order to avoid damaging notch effects due to a too small radius of curvature , e.g. as with known flat ribbon designs j on the hair, is cylindrically shaped in its central area 9a, and the other annular end 10 can be suspended against its elastic restoring force via the axially outwardly projecting pin 5. The ring-shaped end 10 expediently also has a grip tab 11. In the application, the hair is wrapped around the bobbin 1 to produce permanent waves and fixed on the bobbin 1 by means of the ring-shaped end 10 of the retaining strap 9 suspended over the pin 1. In the middle area of the winding body 1 there are three continuous slot-shaped openings 12 one behind the other and, offset by 90, four continuous slot-shaped openings 13.

The surface of the winding body 1 has four axially parallel longitudinal grooves 16 and 16a _3, each offset radially by 90 to one another, the through openings 16 and 16a connecting the two diametrically opposite longitudinal grooves 16 and 16a with one another.

In order to increase the grip of the winding body 1 is the surface of the same in the range along the axially parallel edge of the three continuous slot-shaped openings 16 having two

7733511 02.0Z78

Longitudinal grooves 16 are provided with radially outwardly projecting flops 17.

To increase the manual grip of the bobbin, especially for damp hands of the user are shorter axial longitudinal grooves 19 on the surface of the winding body 1 in the outer area between the continuous round openings 1 * 1 resp. 15 and longer axial longitudinal grooves 20 in the central area on both sides of the diametrically opposite one axially parallel longitudinal grooves l6a arranged.

Due to the special design of the reel-fitting winding body, a weight saving is achieved compared to winding bodies conventionally made of solid material. A further advantage results from the special design of the continuous openings in that excess treatment liquid can penetrate through them into the cavity of the wound body and remain until the end of the treatment.

The distance A defines the center distance of the radial openings in the curler.
