Description

Beginning an air-flow device on a tool that can be placed for hair care and / or hair drying

The invention relates to a tool for hair shaping and / or hair drying, which can be placed on an air-flow device intended for hand use, in particular on a hand-held hair dryer, with an air outlet element with a flat front part and at least one air outlet opening, and a plurality of Hair detection elements, which are essentially rod-shaped, distributed with longitudinal directions parallel to one another and a longitudinal axis of the tool on the front part of the air outlet element, and are oriented therefrom, the tool comprising a carrier body for the hair detection elements, the hair detection elements are supported on a flat front part of the carrier body and are oriented so as to protrude therefrom, the front part of the air outlet element is provided with through openings for the hair detection elements, at least one hair detection element in each case in one passage through the front opening of the air outlet element with play, and the respective front parts of the air outlet element and the carrier body can be displaced relative to one another by the user in the direction of the longitudinal axis of the tool.

Such a tool is known for example from EP-A-0473822 or FR-A-2445615. It is intended to be placed on an air-flow device for the personal needs of a user and then to be brought through the hairstyle of this user so close to her head that at least some of the hair detection elements are essentially in contact with the scalp of the user come into contact, whereupon the tool is moved in the hair to dry the hair.

A similar tool is known from WO-94/14354-A1, in which, however, the hair detection elements are not used. are slidable. According to WO-94/14354-A1, the tool in question serves to bring about the position and volume of the hairstyle, or to comb longer hair dryly. In a known tool of this type, the length of the rod-shaped hair-capturing elements is used in the construction of the tool fixed, and this length can not be changed later. Since this length determines the distance between the front part of the air outlet element and the treated hair or hairline, this distance cannot be changed either. However, the pressure and the temperature of the air flow acting on the hair or the hairline are dependent on this distance. Thus, this pressure and this temperature cannot be adapted to the current and / or individual requirements.

It is therefore the object of the invention to provide a tool of the type mentioned at the outset, in which the user handling the device is able to adapt the usable or effective length of the hair detection elements to the respective type of use of the tool.

To achieve this object, a tool of the type mentioned at the outset is characterized according to the invention by a mechanism with two functional parts for converting a rotary movement of the one functional part into an axial displacement of the other functional part parallel to the longitudinal axis, the two functional parts only being used together with the Air outlet element and the other can only be displaced together with the carrier body in the direction of the longitudinal axis, and one can only be rotated and the other can only be displaced in the direction of the longitudinal axis.

It is thereby achieved that the usable or effective length of the hair detection elements, which protrudes beyond the front part of the air outlet element, can be changed and adjusted by the user by moving the air outlet element and the carrier body relative to one another, this setting being adjusted with the aid of a suitable locking mechanism (for example with a locking screw) or thanks to a suitable breakdown of forces (for example as with a drive with worm and toothed rack).

In this way, the user can optimize the tool for the desired use, for example either to optimally puff up the hairstyle close to the head or to optimally comb longer hair.

It should be noted that the use of the tool according to the invention or of the air-flow device provided with the attached tool and intended for manual use is not limited to shaping and / or drying only the hair of the user handling the device. The user handling the device can very well care for the hair of another person.

If the hair detection elements, possibly excepted in the area of their free end facing away from the carrier body, have a substantially constant cross-section, the length of the hair detection elements set by the user, which projects beyond the front part of the air outlet element, has no appreciable influence on the Exit of the air flow from the air outlet element.

If, on the other hand, the hair detection elements have a cross section that tapers in the direction of the longitudinal axis from the carrier body to their free end facing away from them, the air flow exits the air outlet element not only through the air outlet openings but also through the through openings for the hair detection elements in FIG the free space. Since the variable cross section of the hair detection elements fills the respective passage openings in a variable manner, it is possible for the user to adjust the entire air flow from the air outlet element simultaneously with the adjustment of the length of the hair detection elements. The cross section of the hair detection elements can vary in the longitudinal direction, for example the hair detection elements can be conical, frustoconical or spindle-shaped with double be curved-rounded side surface.

In an exemplary embodiment of the mechanism with two functional parts mentioned, this mechanism comprises a rack on the one hand, and either a pinion or a worm on the other hand, with a rotational movement of the pinion about an axially orthogonal pinion axis or the worm about an axially parallel worm axis Displacement of the rack parallel to the longitudinal axis is implemented.

Another embodiment of the above-mentioned mechanism with two functional parts is a tongue and groove mechanism which implements a rotary movement of one of the functional parts about the longitudinal axis into an axial displacement of the other functional part parallel to the longitudinal axis. The groove is formed as a recess in one of the functional parts and the tongue as a projection on the other functional part. As already stated, one of these two functional parts can only be axially displaced together with the air outlet element and the other only together with the carrier body, while one of these two functional parts can only be rotated about the longitudinal axis and the other can only be displaced axially . Together with a further functional part, which serves to fasten the tool to the device and can be designed as a separate base body or also as part of another functional part, there are various variants of this training example, which essentially differ from one another Distinguish kinematic reversal and / or by other mutual positioning of the functional parts. With respect to the longitudinal axis, a pitch angle in the range of 30 ° to 60 °, for example of approximately 45 °, is recommended for the groove.

The groove can also have one or more latching sections with a smaller pitch, instead of being formed in a straight line with a uniform pitch. The action of external forces on the tongue migrating in the groove is different in the area of the locking sections than in the area between them Areas of the groove lying in the latching sections, and the correspondingly different decomposition of forces leads to the fact that the relative movement of the air outlet element and the carrier body, which is brought about by external forces, is made more difficult if the tongue is in the area of a latching section of the groove. The user perceives this as an aid in setting and keeping the length of the hair detection elements projecting beyond the front part of the air outlet element to predetermined values.

The desired inhibition can also be brought about in that the two functional parts of the mechanism are designed so that they can be snapped together in a detachable manner. For example, a catch spring arranged on one of the two functional parts can interact with a catch provided on the other functional part. In addition, the catch and catch spring can be combined with the groove and its tongue, for example the catch can be formed as a recess in the groove and the catch spring can be combined with the tongue of the groove.

The tool according to the invention basically consists of three functional parts. A first functional part remains immovably attached to the device when the tool is correctly placed on the device. A second functional part can be rotated relative to the first functional part. A third functional part is axially opposite the first functional part, i.e. Can be moved parallel to the longitudinal axis of the tool.

In a first variant, the tool according to the invention is designed as follows:

The first, stationary functional part comprises, in a fixed connection to one another, an annular fastening attachment for fastening the tool to the device, an axial, essentially cylindrical receptacle arranged on this fastening attachment for an essentially cylindrical plug arranged axially on the air outlet element, the air outlet element with the plug mentioned, and a funnel held on the air outlet element. The second, rotatable functional part, in a mutually fixed connection, comprises an axial, annular actuating attachment with an axial cylinder arranged on this actuating attachment, which is provided with the groove.

The third, displaceable functional part comprises, in a fixed connection to one another, the carrier body, on which a spring cooperating with the groove is arranged, and the hair-capturing elements supported on the carrier body.

The rotatable functional part is held in the axial direction between two elements of the stationary functional part, namely between the stationary annular fastening attachment and the stationary funnel.

The displaceable functional part is guided in the axial direction on the axial cylinder and is prevented from rotating by the hair detection elements passing through the passage openings of the air outlet element, the interaction of the hair detection elements with the passage openings also contributing to guiding the carrier body.

In a modification of this first variant, the abovementioned receptacle for the plug arranged on the air outlet element is provided on the device itself, so that the attachment attachment mentioned does not exist as such, while its function is carried out equivalently by elements arranged on the device itself. The rotatable functional part is also held in the axial direction between two elements of the stationary functional part, namely between the stationary funnel and (now equivalent instead of the stationary annular fastening attachment) a suitably designed, standing edge of the device.

In a further modification of the modification described above, the funnel (instead of on the air outlet element) is plugged onto a suitably designed edge of the device and thus held on the device, while the rotatable functional part is displaced between the stationary air outlet element and the stationary funnel and is held in between in the axial direction. Here, too, the rotatable functional part continues to be held in the axial direction between two elements of the stationary functional part, namely between the stationary funnel and (now instead of the stationary annular fastening attachment) the stationary air outlet element.

In a second variant, the tool according to the invention is designed as follows:

The first, stationary functional part comprises, in a fixed connection to one another, an annular fastening attachment for fastening the tool to the device, an axial, essentially cylindrical receptacle arranged on this fastening attachment for an essentially cylindrical plug arranged axially on the air outlet element, and the air outlet element with the connector mentioned.

The second, rotatable functional part comprises, in a mutually tight connection, an axial annular actuating attachment with an axial cylinder arranged on this actuating attachment, which is provided with the groove, and a funnel held on the actuating attachment.

The rotatable functional part is held in the axial direction between two elements of the stationary functional part, namely between the stationary ring-shaped attachment attachment and the stationary air outlet element.

The displaceable functional part is guided in the axial direction on the axial cylinder and is prevented from rotating by the hair detection elements passing through the passage openings of the air outlet element, the interaction of the hair detection elements with the passage openings also contributing to guiding the carrier body. In a modification of this second variant, the mentioned actuating attachment and the funnel held thereon as well as the mentioned axial cylinder are designed as a single element in the rotatable functional part, ie the mentioned firm connection is equivalent here replaced by an integral construction.

In a further modification of this second variant, the above-mentioned receptacle is provided for the plug arranged on the air outlet element on the device, so that the fastening attachment mentioned does not exist as such, while its function is carried out in an equivalent manner by elements arranged on the device itself becomes. The rotatable functional part is also held in the axial direction between two elements of the stationary functional part, namely between the stationary air outlet element and (now equivalent to the stationary annular attachment attachment) a suitably designed, stationary edge of the device.

In a continuation of the above-mentioned modification of the second variant, the mentioned axial cylinder is designed as an integral cylindrical extension of the funnel mentioned, while the groove is formed as a slot in the mentioned cylindrical extension and the spring cooperating with the groove is located radially on the outside Carrier body is arranged.

In a third variant, the tool according to the invention is designed as follows:

The first, stationary functional part comprises, in a fixed connection to one another, the air outlet element with an axially arranged, essentially cylindrical plug, the end of which is designed for fastening the tool to the device, and a funnel held on the air outlet element. A holder matching the end of the plug is then provided on the device, for example the holder and the end of the plug together form a bayonet mount. The second, rotatable functional part, in a mutually fixed connection, comprises an axial, annular actuating attachment with an axial cylinder arranged on this actuating attachment, which is provided with the groove.

The third, displaceable functional part comprises, in a fixed connection to one another, the carrier body, on which a spring cooperating with the groove is arranged, and the hair detection elements supported on the carrier body.

The rotatable functional part is held in the axial direction between an element of the stationary functional part and the stationary device, namely between the stationary funnel and a suitably designed, stationary edge of the device.

In a fourth variant, which can be derived in certain aspects by kinematically reversing the training variants described above, the tool according to the invention is designed as follows:

The first, stationary functional part comprises a funnel which is designed to fasten the tool to the device and on which an axial cylinder provided with the groove is fixedly arranged.

The second, rotatable functional part comprises on the one hand the air outlet element with an axially arranged, essentially cylindrical plug, the end of which is designed for axially fixed but rotatable fastening of the air outlet element on the device, on the other hand in a mutually fixed connection the support body, on which one with the Groove cooperating spring is arranged, and the hair detection elements supported on the carrier body. A fitting to the end of the plug is then provided on the device, for example, the holder and the end of the plug together form a rotatable snap-in socket.

The third, displaceable functional part, in turn, comprises the support body, on which the tongue cooperating with the groove is arranged, and the hair-capturing elements supported on the support body.

The rotatable functional part is held in the axial direction by the interaction of the plug and the holder.

The displaceable functional part is guided in the axial direction on the axial cylinder, the interaction of the hair detection elements with the passage openings also contributing to the guidance of the carrier body.

In addition, the displaceable functional part is carried in rotation by the hair detection elements passing through the through openings of the air outlet element.

In a modification of this fourth variant, the mentioned axial cylinder is designed as an integral cylindrical extension of the mentioned funnel. The groove is thus formed as a slot in the cylindrical extension mentioned, and the spring which interacts with the groove is arranged radially on the outside of the carrier body.

It should be noted that in the direction of the longitudinal axis of the tool, the dimension of the air outlet element is rather small compared to the dimension of the cylindrical extension of the funnel. For more convenient actuation of the tool, the air outlet element can be provided, for example, with a radial actuation pin, lever or knob. Since the groove of the user is accessible from the outside on the cylindrical extension, the actuating pin, lever or knob mentioned can also be guided through the groove and arranged on the carrier body.

Thus, in a further modification of this fourth variant, the mentioned axial cylinder is designed as an integral cylindrical extension of the mentioned funnel and the groove as a slot in the mentioned cylindrical extension, and the spring which cooperates with the groove and is arranged radially on the outside of the carrier body is designed as an actuating pin, lever or knob which is guided through the groove, while the air outlet element has an almost disc-shaped design, ie a small dimension in the direction of the longitudinal axis of the tool .

Between the first, stationary functional part and the second, rotatable functional part it is possible to allow only a relative direction of rotation, for example by one-way rotation inhibition with the aid of a pawl, a freewheel coupling and the like. This measure prevents the hair detection elements from being pushed back by a force exerted thereon.

In addition, the groove can be designed in such a way that it causes at least one complete back and forth movement of the tongue when the cylinder is rotated fully, for example by the track of the groove in a flat development of the surface of the cylinder forming a regular zigzag - course or any other periodic course with one or more periods over a complete rotation of the cylinder results. With such a course of the track, the characteristic curve for the effective length of the hair detection elements can be structurally predetermined as a function of the angle of rotation of the rotatable functional part.

The elements mentioned above can be locked and attached to one another by snapping, welding, gluing, screwing, nailing with pins and similar known means and methods. Rotatable connections can be accomplished in a known manner by snapping in with play.

1, 2 and 3 is an example of a training shown generally designated 1 tool. This tool is intended to be placed on an air-flow device intended for manual use, in particular on a hand-held hair dryer, in order to be used by a user for hair shaping and / or hair drying. A device or a hand hair dryer of the type mentioned is known per se with and without a tool attached, for example from the catalog of Boots Co. Ltd., Nottingham (GB), "Christmaε Gift Guide 1991", page 31, and is therefore not described and illustrated here.

The tool 1 is provided with an air outlet element 2, which has a flat front part 3, on which a plurality of air outlet openings 4 are distributed. The tool 1 is also provided with a plurality of hair detection elements 5 which are essentially elongate and rod-shaped. These hair detection elements 5 lie parallel to one another with their longitudinal directions 6 and a longitudinal axis A of the tool 1, they are distributed on the front part 3 of the air outlet element 2 and are oriented away from them.

The tool 1 comprises a carrier body 7 for the hair detection elements 5. This carrier body 7 is provided with a flat front part 9, which is essentially made of webs 8 like a grid or rust. The hair detection elements 5 are supported on this front part 9, whereby they are oriented so as to protrude from them. Between the webs 8, the front part 9 of the carrier body 7 is pierced in order to allow an air stream coming from the device or hand-held hair dryer to pass through the carrier body 7 in order to exit the tool 1 at the air outlet openings 4.

The front part 3 of the air outlet element 2 is provided with through openings 10 for the hair detection elements 5. In each passage opening 10, a hair detection element 5 crosses the front part 3 of the air outlet element 2 with play. The front part 3 of the air outlet element 2 and the front part 9 of the carrier body 7 the user can move them relative to each other in the direction of the longitudinal axis.

In one variant, which can be seen in particular in FIG. 1, the play of the hair detection elements 5 in their respective passage opening 10 is dimensioned such that it allows the hair detection elements 5, with ease in the direction of their longitudinal direction 6 relative to the air outlet element 2 to be moved, but no appreciable air flow allowed to emerge from the tool 1 at the passage openings 10. Therefore, the hair detection elements 5 are essentially, i.e. except in the region of its free end 11 facing away from the carrier body 7, provided with a constant cross section corresponding to the respective passage opening 10, i.e. formed in a substantially cylindrical manner. However, this cylindrical shape does not need to be circular-cylindrical, because the hair detection elements can also be elliptical in cross section, as can be seen in FIG. 4, or still cruciform, etc.

In another variant, in which a weak air flow is allowed to emerge from the tool 1 at the passage openings 10, the hair detection elements have a cross section, as can be seen in particular in FIG Direction of the longitudinal axis A tapers from the carrier body 7 to the free end 11 of the hair detection elements 5 facing away from it.

A mechanism that can be actuated by the user is provided for displacing the front part 3 of the air outlet element 2 and the front part 9 of the carrier body 7 relative to one another in the direction of the longitudinal direction 6 of the hair detection elements 5 parallel to the longitudinal axis A. In order to describe this mechanism in a different training variant, its underlying general concept is first explained.

The tool 1 according to the invention comprises three functional parts, namely a stationary first functional part, a rest in one of its various design variants. - 16 -

a second functional part rotatable relative to the stationary functional part and a third functional part displaceable relative to the stationary functional part.

The mechanism mentioned generally comprises two functional parts, namely the rotatable second and the displaceable third functional part, and this mechanical mechanism is generally intended to convert a rotary movement of the second functional part into an axial displacement of the third functional part parallel to it Longitudinal axis A to effect. Of the two functional parts of the mechanism, one can only be displaced in the direction of the longitudinal axis together with the air outlet element and the other only together with the carrier body. In addition, of the two functional parts of the mechanism, one can only be rotated relative to the stationary functional part and the other can only be displaced relative to the stationary functional part in the direction of the longitudinal axis.

In the case of the different design variants of the invention, however, each of the other elements of the tool 1 are assigned to the stationary first functional part, the rotatable second functional part and the displaceable third functional part.

In particularly preferred embodiments of the named mechanism, one of the two functional parts of the mechanism is provided with a recess designed as a groove and the other with a spring that engages in the groove and is designed as a cylindrical projection.

For example, in the embodiment of the tool 1 shown in FIGS. 1-3, the mechanism mentioned consists of the combination of a groove 12 and a cylindrical projection 13 which engages in the groove 12. This cylindrical projection 13 is best visible in FIG. 13, in which the same training example is shown, but the plane of the longitudinal section of FIG. 13 is at right angles to the plane of the longitudinal section of FIG. 3.

The first, stationary functional part of the tool 1 comprises a ring-shaped connection in a mutually fixed connection Attachment attachment 14 for attaching the tool 1 to the device (not shown), and an axial receptacle 15 arranged on this attachment attachment 14 for an essentially cylindrical plug 16 axially arranged on the air outlet element 2, and further the air outlet element 2 itself, together with the latter mentioned connector 16, and also a funnel 17 held on the air outlet element 2.

The second, rotatable functional part of the tool 1 comprises, in a mutually fixed connection, an axial, annular actuating attachment 18 with an axial cylinder 19 arranged thereon and provided with the groove 12.

The third, displaceable functional part of the tool 1 comprises, in a mutually rigid connection, the carrier body 7, on which the tongue cooperating with the groove 12 or the relevant cylindrical projection 13 is arranged, and the hair-capturing elements 5 supported on the carrier body 7. 3, the spring or the cylindrical projection 13 lies in the middle behind the track of the axis A on the upper part of the groove 12 and is therefore completely covered in the view by the plug 16 and the cylinder 19.

1-3, the second, rotatable functional part (actuating attachment 18 with cylinder 19) defined in the above is in the axial direction between two elements of the first, stationary functional part defined in the above (fastening attachment 14, Receptacle 15, air outlet element 2 together with plug 16, funnel 17), namely held between the fastening attachment 14 and the funnel 17.

Finally, furthermore, in this embodiment example of the tool 1 shown in FIGS. 1-3, the third, displaceable functional part (carrier body 7 with spring or projection 13 and hair-capturing elements 5) is guided in the axial direction on the axial cylinder 19, and it is prevented from rotating by the hair detection elements 5 passing through the passage openings 10 of the air outlet element 2.

In a variant, the receptacle 15 can be provided on the device. hen and be part of the device itself, and in another variant, the funnel 17 can be attached to a correspondingly designed edge of the device and can be held there. In these two variants, tool 1 then remains firmly attached to the device.

As shown in FIG. 2 and partially enlarged in FIG. 16, the groove 12 can have a variable slope with one or more latching sections 23 with respect to the longitudinal axis A of the tool 1, in the area of which the slope the groove 12 is smaller than outside this area. If the spring 13 is located in the region of a latching section 23, the user perceives this as an aid in setting and maintaining the length of the hair detection elements which protrude beyond the front part of the air outlet element to predetermined values.

5, there are other elements of the tool 1 which are assigned to the stationary first functional part, the rotatable second functional part and the displaceable third functional part.

The first, stationary functional part comprises the fastening attachment 14, the receptacle 15 and the air outlet element 2 with the plug 16 in a fixed connection to one another.

The second, rotatable functional part, in a mutually fixed connection, comprises the actuating attachment 18 with the cylinder 19 provided with the groove 12, and the funnel 17 held on the actuating attachment 18 in order to connect the funnel 17 in a rotationally fixed manner to the actuating attachment 18.

The third, displaceable functional part, in a fixed connection to one another, comprises the carrier body 7 with the spring or the projection 13 and the hair detection elements 5.

In this exemplary embodiment of tool 1 shown in FIG. 5, the second rotatable functional part (actuating attachment 18 with cylinder 19 and funnel 17) defined in this context is between in the axial direction two elements of the first, stationary functional part (fastening attachment 14, receptacle 15 and air outlet element 2 with plug 16), namely held between the fastening attachment 14 and the air outlet element 2.

Finally, in this embodiment of the tool 1 shown in FIG. 5, the third, displaceable functional part (carrier body 7 with spring or projection 13 and hair-sensing elements 5) on the axial cylinder 19 is guided in the axial direction, and it is guided prevented by the hair detection elements 5 passing through the through openings 10 of the air outlet element 2 from rotating.

It should be noted in the case of the groove 12 shown in FIG. 5 that the latter - in the sense of an illustration - is formed here in a straight line with a uniform slope.

In a variant of this training example shown in FIG. 5, the actuating attachment 18, the funnel 17 and the cylinder 19 can be integrated in the rotatable functional part or, if necessary, as a result of a definitive fastening, for example by gluing or welding as a single one Element be formed.

5, as in the embodiment example of FIGS. 1-3, in another variant, the receptacle 15 can be provided on the device and can be part of the device, the tool 1 then remaining firmly attached to the device. In particular, as can be seen in the schematic illustration in FIG. 6, the cylinder 19 as an integral cylindrical extension 60 of the funnel 17 and the groove 12 can be designed as a slot 61 in the extension 60, the one with the Groove 12 cooperating spring 13 is formed as a projection 62 arranged radially on the outside of the carrier body 7, which can also represent the web of an element 63, which acts as an actuating pin, lever or knob for moving the functional parts in question, which is guided through the groove is formed to each other.

If desired, a limitation of the relative Rotational movement of the second, rotatable functional part can be provided, for example by the interaction of a radial projection 52 arranged on the actuating attachment 18 with a slot 53 arranged on the attachment attachment 14, into which a correspondingly angled end 54 of the projection 52 engages, so that the ends of the slot 53 serve as stops for the movement of the end 54 of the projection 52.

In the case of a training example shown in FIG. 7, there are in turn other elements of the tool 1 which are assigned to the stationary first functional part, the rotatable second functional part and the displaceable third functional part.

The first, stationary functional part comprises the air outlet element 2 with the plug 16 and the funnel 17 in a tight connection with one another. The plug 16 has a free end 70, which is designed to fasten the tool 1 on the device, one on the device (Not shown) to the end 70 of the plug 16 fitting bracket is provided. For example, the tool 1 or the end 70 of the plug 16, as indicated in FIG. 7, can be fastened to the device with a bayonet lock.

The second, rotatable functional part comprises the actuating attachment 18 with the cylinder 19 provided with the groove 12 in a mutually tight connection.

In this embodiment of the tool 1 shown in FIG. 7, the second rotatable functional part (actuating attachment 18 with cylinder 19) defined in this context is in the axial direction between two elements of the first, stationary functional part (air outlet element 2 with plug 16 and funnel 17), namely held between the air outlet element 2 and the funnel 17.

Finally, furthermore, in this embodiment of tool 1 shown in FIG. 7, the third displaceable functional part (carrier body 7 with spring or projection 13 and hair detection elements 5) on the axial cylinder 19 is guided in the axial direction, and it is prevented from rotating by the hair detection elements 5 passing through the openings 10 of the air outlet element 2.

8, there are still other elements of the tool 1 which are assigned to the stationary first functional part, the rotatable second functional part and the displaceable third functional part.

The first, stationary functional part comprises the funnel 17 and the cylinder 19 with the groove 12 in a fixed connection to one another. The funnel 17 is designed to fasten the tool 1 to the device, for example, it is attached to the edge of the Device attachable bar. The funnel 17 is preferably attached to the device in a rotationally fixed manner, for example with the aid of a recess 81 provided on the funnel 17, which (analogously to the recess 51) interacts with a projection (not shown) which is provided on the edge of the device iεt to connect the funnel 17 with the device.

The second, rotatable functional part comprises two subassemblies, namely the air outlet element 2 with the plug 16 in a connection that is fixed to one another, and the support body 7 with the spring or projection 13 and the hair detection elements 5 in a connection that is fixed to one another. These are two subassemblies essentially rotationally fixed to one another, but not rigidly connected to one another in the axial direction, as will be explained in the following. The plug 16 has a free end 80 which is designed for the axially fixed but rotatable fastening of the air outlet element 2 to the device, a holder (not shown) which fits the end 80 of the plug 16 being provided on the device. For example, the end 80 of the plug 16, as indicated in FIG. 8, can be fastened to the device with a rotatable snap connection. The third, displaceable functional part comprises, in a fixed connection to one another, the carrier body 7 with the spring or the projection 13 and the hair detection elements 5. This third, displaceable functional part thus forms the one of the aforementioned assemblies, namely an axially displaceable assembly (carrier body 7 with spring or projection 13 and hair detection elements 5), while the other assembly (air outlet element 2 with connector 16) cannot be moved axially.

In the embodiment of the tool 1 shown in FIG. 8, the two assemblies of the second rotatable functional part defined in this context (air outlet element 2 with plug 16 on one side, support body 7 with spring or projection 13 and hair detection elements 5 on the other side) are in held in axial direction by the interaction of the plug 16 and the matching holder on the device. The displaceable functional part or the axially displaceable assembly (carrier body 7 with spring or projection 13 and hair detection elements 5) is guided in the axial direction on the axial cylinder 19 and rotated by the hair detection elements 5 passing through the openings 10 of the air outlet element 2 entrained, which was referred to above as "assemblies which are essentially non-rotatable relative to one another".

Also in this embodiment shown in FIG. 8, as can already be seen in the schematic representation of FIG. 6, the cylinder 19 as an integral cylindrical extension 60 of the funnel 17 and the groove 12 as a slot 61 in the extension 60 can be formed , in which case the tongue 13 cooperating with the groove 12 is designed as a projection 62 arranged radially on the outside of the carrier body 7, which can also represent the web of an element 63 which, as an actuating pin, lever or knob, passes through the groove Moving the relevant functional parts to each other is formed.

In order to distinguish between the stationary and the rotating To allow only a single relative direction of rotation, there is a corresponding one-way rotation inhibition, for example, as it is shown in FIG. 2, for example, of a circular pawl track 20 which is arranged on the rotatable actuating attachment 18 and which interacts with pawls 21 arranged on the stationary funnel 17.

The groove 12 shown in FIG. 2, for example, produces exactly one complete reciprocating movement of the spring 13 when the cylinder rotates one full turn. The corresponding track of the groove 12 is essentially triangular in a flat development of the outer surface of the cylinder 19 . It is understood that with a different, possibly multiple, course of the groove 12, a different course of the tongue 13 with possibly several periods can be obtained over a complete rotation of the cylinder 19.

If desired, the tool 1 can be locked on the device, for example, with the aid of a bayonet lock 22 provided on the fastening attachment 14 (see, inter alia, FIGS. 2 and 3).

In the case of a training example shown in FIG. 9, there are still other elements of the tool 1 which are assigned to the stationary first functional part, the rotatable second functional part and the displaceable third functional part.

The first, stationary functional part comprises, in a mutually fixed connection, the air outlet element 2 with the plug 16 and the funnel 17. The plug 16 has a free end 90, which is designed for the rotationally fixed fastening of the air outlet element 2 on the device, on the device a holder (not shown) fitting to the end 90 of the connector 16 is provided. For example, the end 90 of the connector 16, as indicated in FIG. 9, can be fastened to the device with a lockable bayonet connection. With regard to the funnel 17, its rotationally fixed attachment to the air outlet element 2 is not critical; the funnel 17 can be attached to the air outlet element 2, for example, with a simpler snap connection. be attached.

The second, rotatable functional part comprises the actuating attachment 18 with the cylinder 19 provided with the groove 12 in a connection that is fixed to one another.

In the embodiment of the tool 1 shown in FIG. 9, the second, rotatable functional part (actuating attachment 18 with cylinder 19) defined in this context is in the axial direction between the stationary funnel 17 and a suitably designed, (not shown) stationary edge of the Device held. This edge of the device thus plays the role of an additional element of the first, stationary functional part, and in this sense the second, rotatable functional part is analogous to the other training examples between two elements of the first, still functional part, here held between each element of the stationary functional part (air outlet element 2 with plug 16 and funnel 17) and the device standing still.

Finally, furthermore, in this embodiment example of the tool 1 shown in FIG. 9, the third, displaceable functional part (carrier body 7 with spring or projection 13 and hair-sensing elements 5) is guided in the axial direction on the axial cylinder 19, and it is guided prevented from rotating by the hair detection elements 5 passing through the passage openings 10 of the air outlet element 2.

In the foregoing, in connection with FIGS. 1-3, an embodiment example of the tool 1 has been described, that is shown in FIG. 3 in a longitudinal section with the hair elements fully extended. To complete the description, the same embodiment is again shown in FIG. 10 in longitudinal section, but with approximately half retracted hair-capturing elements, and in FIG. 11, the same training example again in longitudinal section, but with shown completely retracted hair detection elements.

FIG. 12 shows a further design example of the air outlet element 12 of the tool 1 in a plan view. In this embodiment example, passage openings 10 are shown on the one hand, in which, analogously to FIG. 4, only one hair detection element 5 crosses the front part 3 of the air outlet element 2 in the passage opening 10 with play. On the other hand, through openings 120a and 120b are shown in FIG. 12, in which, in contrast to FIG. 4, two hair detection elements 125a and 125b or 125c and 125d, respectively, the front part 3 of the air outlet element 1 in the through opening 120a or Cross 120b with play - however, more than two hair detection elements could also be provided in a passage opening of the air outlet element. This results in more flexible design options for the construction of the tool 1.

Another embodiment of the tool 1 is shown in longitudinal section in FIG. 14. A mechanism with a toothed rack 140 and a pinion 141, the respective toothings of which mesh with one another, serves as the drive for the support body 7. The rack 140 extends parallel to the longitudinal axis A of the tool 1 and is firmly connected to the carrier body 7, so that the movement of the rack 140 takes place parallel to the longitudinal axis A of the tool 1. The pinion 141 has a pinion axis 142 which is orthogonal to the longitudinal axis A and a shaft 143 which is fixedly connected to pinion 141 and which extends orthogonally to the axis A to the outside of the tool 1 and allows an operator to rotate the pinion 141 and thus the rack 140 and thus also to move the carrier body 7 parallel to the longitudinal axis A.

In Fig. 15 a still further embodiment example of the tool 1 is shown in longitudinal section. A mechanism with a toothed rack 150 and a worm 151, the respective toothings of which mesh with one another, serves as the drive for the support body 7. The rack 150 extends parallel to the longitudinal axis A of the tool 1 and is firmly connected to the carrier body 7, so that the rack 150 is moved parallel to the longitudinal axis A of the tool 1. The screw 151 is coaxial with the screw axis 152 of the longitudinal axis A of the tool 1, and it is firmly connected to the actuating attachment 18. This allows an operator to turn the worm 151 by rotating the actuation set 18 and thus to shift the rack 150 and thus also the carrier body 7 parallel to the longitudinal axis A. In a variant, the screw axis 152 could also lie only parallel to the longitudinal axis A of the tool 1 without being coaxial therewith.

It should also be pointed out that an embodiment equivalent to the tool 1 according to the invention can be seen in transferring the function of the air outlet element 2 to other elements of the tool and apparently emitting the air outlet element 2, but in reality by means of the equivalent replace. For example, the function of the air passage can be ensured by the fact that the carrier body 7 on its front part 3 carrying the hair detection elements 5 is not covered by any physically existing air outlet element. The flat front part of the air outlet element is then represented by the edge of the funnel, which itself defines and forms both an air outlet opening and a passage opening, which is crossed by the total number of hair detection elements. Of course, in order to ensure the interaction of the air outlet element with the carrier body (ie to exercise the function of entraining in rotation or preventing rotation), a corresponding interaction between the carrier body and another part (fastening attachment, funnel, actuation attachment) must be provided, for example by means of a groove provided on the funnel parallel to the axis and a projection provided on the support body and engaging in the groove. Other equivalent solutions of this type are conceivable without the inventive step. List of reference numbers
