Description

The invention relates to a hair straightening attachment for hair dryers, comprising a base body and a feed unit arranged thereon, on which rigid tines aligned parallel to one another are formed.

In order to be able to smooth wavy hair effectively, it requires a stream of air on the initially usually towel-moist hair to be smoothed and a simultaneous pulling action. For smoothing, a warm air stream is first used, wherein the wavy hair is pulled and smoothed under pulling action. Subsequently, a cold air flow is used for fixing.

Hair straighteners for hair dryers are variously known in the art.

For example, describes the WO98 / 12944 a device for straightening hair. This comprises an upper body, which has a heat-conducting plate, and a comb and a lower part, with which the device can be mounted on a hair dryer.

Likewise describes the US 3,065,759 an apparatus and method for straightening hair. This device comprises a comb with a plurality of parallel tines, a device for heating the hair, which is located within the comb, and a heat-conducting tubular part.

All of the hair-removal tips for hair-dryers available in the prior art have the disadvantage that hair close to the head is often not or only insufficiently grasped, and that even when the hair is captured by the sanding attachment, a relatively large area of the hair, from the scalp to the brush body , is not treated accordingly.

On this basis, the present invention has the object to provide a comparison with the prior art improved Glättaufsatz for hair dryer that captures in particular the hair close to the head as well as possible, and / or the longest possible area of the detected hair, from scalp to brush body, treated accordingly.

This object is achieved for a hair straightening attachment for hairdryers, comprising a base body and a feed unit arranged thereon, on which rigid tines aligned parallel to one another are formed, in that bristles are arranged between the rigid tines of the feed unit.

The hair straightening attachment for hair dryers according to the invention achieves markedly improved results over the prior art.

The feeder unit lifts a strand of hair and guides it to bristles arranged on the bristle body. The bristles hold the strands of hair by friction and thus generate the necessary for a smoothing traction. Thus, a friction is exerted by a combination of rigid prongs and bristles, which causes the required tensile force on the hair to be smoothed. Advantageous embodiments and further developments of the invention, which can be used individually or in combination with each other, are the subject of the dependent claims.

Thus, in an advantageous embodiment, the prongs protrude laterally beyond the base body at least on one side. This embodiment has the advantage that the tines which protrude laterally beyond the base body on at least one side catch the hair and supply it to the bristles. As a result, it can be better kept and smoothed by the bristles.

In a further advantageous embodiment, the Haarglättaufsatz on tines, which protrude laterally on opposite sides of the main body. This embodiment allows the hair to be passed over a longer range, thus improving the pulling force on the hair.

Preferably, at least two bristles are arranged between the rigid prongs of the feed unit, which have a different flexibility.

It has proven to be advantageous if one bristle are made of a softer material than the other bristles or vice versa. The bristles are preferably made of wild boar bristle and / or horsehair and / or polyacrylic and / or polyethylene and / or polypropylene. These materials have shown the best results in hair straightening.

In a preferred embodiment, the bristles have a thinner diameter than the other bristles or vice versa. The bristles preferably have a diameter of 0.1 to 1.2 mm; preferably 0.15 to 0.8 mm; more preferably 0.2 to 0.5 mm; and most preferably 0.3 mm.

In a further advantageous embodiment, the bristles are shorter than the other bristles or vice versa. The bristles preferably have a length of 12 to 20 mm; preferably 14 to 16 mm. This mixed size distribution of the bristles captures and holds the hair in a particularly advantageous manner.

Thus, e.g. thick and / or hard and so far rigid bristles a fine guide or sorting of the hair. In contrast, thin and / or soft and in so far more flexible bristles ensure a shine in the hair. Both bristles, more flexible and less flexible together, with proper distribution, provide the ideal pull on the hair. This means that the pull is neither too strong, which could cause the hair to break or be too weak, which could cause the hair to be insufficiently smoothed.

Bristle mixtures have proven to be advantageous in which the thick and / or hard and so far rigid bristles account for 2 to 30%; preferably 5 to 25%; and most preferably make up 10% of the total bristle mixture.

It has proven to be advantageous if one bristle is more densely distributed with respect to the other bristles or vice versa. The bristles have a bristle density of 200 to 600 bristles per cm ² ; preferably 300 to 500 bristles per cm ² ; and more preferably 400 bristles per cm ² .

Preferably, in the hair straightening attachment, the bristles are supported by at least one bristle attachment.

In a further preferred embodiment, one part of the bristles is arranged on a first bristle attachment, and another part on a second bristle attachment, which is designed such that it can be retracted relative to the first attachment attachment in such a way that a part of the bristles is brought into and out of operative engagement. This embodiment has the advantage that the number of bristles in contact with the hair can be varied. Increasing the number of bristles in contact with the hair increases the tensile force on the hair.

It has proven to be particularly advantageous if the surface of the bristle headpieces is rounded. If the surface of the bristle attachments is round, the tensile force can be varied by varying the angle of penetration of the appliance into the hair. By screwing in the effective friction angle of the brush increases. As a result, a higher frictional force is caused, which can dose a user according to his needs on the Einschlingwinkel. By varying the Eindrehwinkels and the number of engageable bristles, the tensile force of the brush can be adjusted individually to different hair strengths and densities.

As a result of the hair straightening attachment for hair dryers according to the invention, significantly improved results with regard to hair straightening and hair care are achieved in comparison with the prior art.

Further advantages and embodiments of the invention will be described below with reference to embodiments and with reference to the accompanying drawings.
