Description

The present invention relates to an attachment for a hair care device with a tubular body and a carrier body, on which bristles are formed.

Hair care devices, such as warm air brushes or styling brushes, usually have an attachment made of a tubular hollow body and a carrier body arranged in the hollow body, on which retractable bristles are arranged. To treat hair with this device, the hairs are wound over the hollow body when the bristles are extended. After the hair treatment, the bristles are drawn into the interior of the hollow body by means of an actuating element, so that the hair can be easily detached from the hollow body.

Such hair devices with retractable bristles are for example from the publications DE 20 2010 008 499 U1 . DE 200 19 552 U1 and DE 299 15 051 U1 known. From the US 2010 0200011 A1 a brush with openings for retractable bristles is also known, which are arranged in a common recess.

When using such known hair care devices, however, bristles can disadvantageously bend. These bent bristles are drawn into the interior of the hollow body after the hair treatment to loosen the hair. There is a risk that these retracted and bent bristles get caught in the interior of the hollow body and thus cannot be moved out of the interior of the hollow body again. Even a bent bristle prevents all the bristles of the hair care device from extending, since the bristles can be retracted or retracted using a common mechanism. A further use of this hair care device is therefore disadvantageously no longer possible.

It is therefore an object of the present invention to provide an improved attachment for such a hair care device and an improved hair care device which are distinguished by more reliable use, in particular by avoiding bristles which are caught.

This object is achieved by an attachment for a hair care device with the features of claim 1. This object is further achieved by a hair care device with the features of claim 10. Advantageous developments of the invention are the subject of the dependent claims.

According to the invention, an attachment is provided for a hair care device which has a tubular body in which openings are formed and a carrier body which is arranged inside the tubular body and on which bristles are arranged. The bristles reach through the openings of the tubular body in a flared state. In a retracted state, the bristles are drawn into the tubular body at least in some areas. The openings are arranged at least in a recess in the tubular body.

The tubular body is preferably a hollow body, in particular a perforated roller-shaped plate, which preferably has openings which are arranged uniformly. The openings serve for the passage of the bristles. For this purpose, the bristles are preferably transferred from the issued state into the retracted state by means of an actuating element.

The tubular body, in particular the entire attachment, is designed as a three-dimensional body which, among other things, has a direction of longitudinal extension. The longitudinal direction extends along the axis of the tubular body.

According to the invention, the openings of the tubular body are arranged at least in one depression. As a result, recessed bristle openings can advantageously be realized. In the retracted state, the bristles are in a lower position than the conventionally known retractable bristles. The at least one depression is formed by the perforated plate of the tubular body. The bristle drawn into the respective opening is arranged at least in regions in the depression and is thus surrounded by the plate. The drawn-in bristle preferably does not protrude above the depression. This means that the retracted bristle is completely sunk into the recess.

With these recessed bristle openings, the risk can advantageously be reduced or even completely avoided that bent bristles get caught inside the tubular body when they are extended and thus cannot be extended again. The at least one depression of the tubular body advantageously serves as a guide rail for curved bristles.

In a preferred development of the invention, the tubular body comprises an opening-encompassing plane and a hair treatment plane. The plane encompassing the opening is at a smaller distance from the carrier body than the hair treatment plane.

A plane encompassing the opening is to be understood as a plane of the tubular body which has the openings. That means in this Level the openings of the tubular body are arranged. In addition, the tubular body has a further level, the hair treatment level. This level is intended for hair treatment. This means that the hair to be treated at this level is in direct contact with the attachment during the hair treatment.

The hair treatment level and the opening-encompassing level form different levels of the tubular body. The plane encompassing the opening is arranged closer to the carrier body than the hair treatment plane. This means that the plane encompassing the opening is set into the tube body in comparison to the hair treatment plane. This offset forms the at least one depression, which advantageously serves as a guide rail for the bristles.

In a further preferred development of the invention, the bristles each comprise bristle heads which are arranged in the at least one recess in the retracted state. In the retracted state, the bristle heads are preferably completely sunk in the at least one recess. The bristle heads are therefore preferably completely surrounded or enveloped by the tubular body in the retracted state.

In the retracted state, the bristle heads are preferably arranged on the side of the openings facing away from the carrier body. When the bristles are drawn in or out, the bristle heads are not guided through the openings. In both states, the bristle heads thus remain on the same side of the respective opening, in particular on an outer side of the tubular body. The bristle heads are preferably arranged above the openings in both states. Above means that the bristle heads do not reach through the openings or are not passed through the openings when the conditions change.

The depressions are preferably each formed in a trench-like or trough-like manner. Each depression preferably has a base area, in particular the plane encompassing the opening, and side areas which merge into the hair treatment plane. The base surface is preferably spaced from the hair treatment level by means of the side surfaces. The distance between the base surface and the hair treatment surface is particularly preferably at least as large as or larger than the bristle head, so that the bristle head is advantageously completely surrounded by the side surfaces.

According to the invention, exactly one opening is assigned to each bristle, each opening being arranged in exactly one recess. Advantageously, each bristle is assigned a guide rail which prevents the bristles from getting caught in the openings within the tubular body.

The depressions are preferably each funnel-shaped or crater-shaped. The opening is formed on the narrower side of the depression. As a result, the bristle heads can be accommodated in the recess even when drawn in.

In one of the conventionally designed attachments, each bristle is assigned exactly one opening, openings which are arranged adjacent to one another along the longitudinal direction of the attachment being arranged in a common depression. The common depression is preferably formed in a straight line or in an axis shape along the axis of the tubular body.

The tubular body in this case preferably has a plurality of depressions arranged in rows, which extend uniformly over the tubular body. Each row preferably has a plurality of openings lying next to one another.

In a further preferred development of the invention, the at least one depression is formed by a perforation process, in particular by a punching process.

In a further preferred development of the invention, a hair care device with an attachment according to the invention is used. The attachment can be detachable from the device or attached to the device or fixedly attached.

In a further preferred development of the invention, the hair care device is used to brush, wave or curl the hair. The hair care device is preferably a warm air brush or a styling brush.

Further advantages, advantageous embodiments and developments of the hair care device result from the following in conjunction with the 1 to 3 described embodiments. Show it

• 1A . 1B , each a schematic view of an embodiment of a hair care device according to the invention, and
• 2A . 2 B . 3A to 3E each a schematic view of an embodiment of a conventional hair care device.

In the exemplary embodiments and figures, identical or identically acting components can be used each be provided with the same reference numerals. The components shown and their size relationships to one another are fundamentally not to be regarded as true to scale. Rather, individual elements such as, for example, layers, parts, elements, components and areas can be shown in an exaggeratedly thick or large dimension for better representation and / or for better understanding.

In the 2A . 2 B and 3A to 3E schematic sections of a conventional attachment for a hair care device, in particular a warm air styling brush, are shown. 3A shows an essay showing a tubular body 11 has, which is designed as a cylindrical or roller-shaped plate and forms a hollow body. This plate has a plurality of perforations which are arranged regularly, in particular in a matrix, on the plate. The perforations form a plurality of regularly arranged openings 12 in the plate of the tubular body 11 out.

In the tubular body 11 , i.e. in the interior of the tubular body 11 , a carrier body is arranged (not shown) on which a plurality of bristles 21 is attached, each at the opposite end of the attachment a bristle head 22 exhibit. The bristles 21 are like the openings 12 regularly, in particular matrix-like, attached to the carrier body. In particular, every bristle 21 exactly one opening 12 assigned to the tubular body. The bristles grip when they are on display 21 through the openings 12 therethrough. In particular, the largest proportion of the respective bristle reaches through the respective opening, so that the bristles 21 spiky or brush-like from the tubular body 11 protrude.

This exposed condition of the bristles 21 is in 3A shown.

The bristles 21 also have a retracted state in which they are at least partially in the tubular body 11 have moved in. In particular, the largest proportion of the respective bristle is drawn into the tubular body. Only a small proportion of the respective bristle head 22 protrudes into or through the respective opening.

The condition of the bristles is in 3B shown.

In 3C is a two-dimensional cross section of two in the tubular body 11 retracted bristles 21 shown. 3D shows a three-dimensional view of this. The tubular body 11 points for the two bristles 21 two circular or round openings 12 on. The bristles 21 are completely in the tube body 11 moved in. In particular, the bristle heads also protrude 22 not from the respective opening 12 over the tubular body 11 out.

With such, as conventionally designed attachments, there is a risk that bristles will bend when using the attachment or the associated hair care device. These bent bristles 23 often tilt in the retracted state within the tube body 11 , especially at the edge of the respective opening 12 , This problem is in 3E shown.

In the case of a tilted bristle 23 can all bristles 21 of the essay can no longer be transferred from the retracted state to the exhibited state. A canted bristle is therefore sufficient so that all other bristles of this attachment get caught in the interior of the tube body. In this case, the attachment can no longer be used for hair treatment, since the hair treatment is carried out when the bristles are on display.

In order to minimize or prevent this risk, the invention provides for the openings of the tubular body to be arranged at least in a recess in the tubular body or the roller-shaped plate. Refinements for this are in the following in connection with the 1 and 2 explained in more detail.

1A shows a two-dimensional cross section of two in the tubular body 11 retracted bristles 21 , The tubular body 11 unlike a conventional tubular body, each has a recess 13 in the area of an opening 12 on. That means every opening 12 of the tubular body in a recess 13 is arranged. To these recesses 13 To form in the tubular body, the roller-shaped plate of the tubular body is punched funnel-shaped or crater-shaped. This creates funnel-shaped or crater-shaped depressions 13 with preferably sloping side surfaces. The depressions each serve as a guide rail for the respective bristle 21 ,

Through the wells 13 are the bristle heads 22 in the retracted state from the edges of the respective opening 12 surrounded in a lower position than with conventional essays. This minimizes the risk of bent bristles on the edges of the openings 12 get caught and thereby prevented from getting into the exhibited state. The bristle heads are arranged above the respective opening, in particular in the retracted state, so that tilting below the opening is not possible. In particular, the bristle heads are located 22 in the retracted state in the respective recess.

Through the wells 13 includes the tubular body 11 a level encompassing the opening H2 and a hair treatment level H1 , The level that encompasses the opening H2 a smaller distance from the carrier body than the hair treatment level H1 , That means that the opening encompassing level H2 further inside the tube body 11 is arranged as the hair treatment level H1 , At the hair treatment level, the hair in particular is guided for hair treatment. At the level covering the opening H2 on the other hand, the hair is not guided to the hair treatment. This only serves to guide the bristles and to avoid the risk of bristle tilting.

1B shows a three-dimensional view of the embodiment of FIG 1A ,

In 2A Another example of a conventional attachment is shown. In contrast to the embodiment of the article of the invention 1A . 1B is not every opening 12 of the tubular body 11 a deepening 13 assigned. In particular, the recesses 13 rectilinear or axis-shaped along the axis or the longitudinal direction L of the tubular body. openings 12 that along a common line along the longitudinal direction L of the essay are arranged side by side, are in a common recess 13 educated. The wells 13 accordingly cover the tubular body in rows.

2 B shows a section A out 2A , The axis or longitudinal direction of the attachment runs into the sheet plane. Accordingly, the axis-shaped depression also runs 13 into the leaf plane. To form the depressions 13 is the plate of the tubular body 11 bent so that the two levels H1 . H2 are trained. This makes the hair treatment level H1 and the level encompassing the opening H2 educated. The bristle heads 22 the bristles 21 lie in the recess in the recess above the respective opening 12 , so that again advantageously the bristles tilt 21 is prevented at the respective opening edge.

The explanation of the attachment according to the invention for a hair care device on the basis of the exemplary embodiments described above should not be regarded as restricting the invention to these. Rather, the invention encompasses every new feature and every combination of features, which includes in particular every combination of features in the patent claims, even if this feature or this combination itself is not explicitly specified in the patent claims or the exemplary embodiments.
