Description

The invention relates to a tool for hair styling and / or hair drying based on a use for hand use air-flow device, especially on one Hand hair dryer, is attachable, according to the preamble of Claim 1.

Such a tool is for example from US-A-5275339 known.

A similar tool is also for example from WO-94/14354-A1 known.

Such tools are designed for a flow of air Device of a user's personal needs put on and then through this user's hairstyle to be brought so close to her head that at least some of the hair capture elements essentially come into contact with the scalp of the user, whereupon the tool is moved in the hair to close the hair drying, bringing about the level and volume of the hairstyle, or to comb longer hair dry.

In these known tools, the length of the rod-shaped Hair detection elements in the construction of the Tool set, and this length cannot be changed later become. Because this length is the distance between the front section of the air outlet element and the treated hair or hairline determined, this distance can not be changed become. From this distance are the pressure and the Temperature of the acting on the hair or the hairline Airflow dependent. So this pressure and this Temperature not the current and / or the individual Can be adjusted as required.

Similar tools are also from EP-A-0473822, for example or FR-A-2445615. With these known tools are the rod-shaped hair detection elements against Spring force slidable, and they are pressed into the tool, when she presses the user onto her scalp. The user can thus determine the effective length of the Do not determine rod-shaped hair detection elements in advance and hold on during use.

The object of the invention is therefore a tool Provide the type mentioned, in which it is the Device handling user is possible, the usable or effective length of the hair detection elements to the respective Adapt the way the tool is used.

To solve this problem is a tool of the beginning mentioned type according to the invention characterized by the im Claim 1 defined combination of features.

Advantageous embodiments of the invention are in the dependent Defined claims.

In the inventive design of the tool are front parts of an air outlet element and a carrier body longitudinally displaceable by the user relative to each other. The mechanism in question comprises two functional parts and sets a rotary motion of one of the functional parts into an axial longitudinal displacement of the other. Here is one of the functional parts only together with the air outlet element and the other only together with the carrier body longitudinally displaceable, and one of the functional parts only rotatable and the other only longitudinally displaceable, the assignment of the functional parts for the air outlet element or carrier body and for rotatability or longitudinal displacement, depending on the considered training example, in different combinations can be done.

With the design of the tool according to the invention it is achieved that the usable or effective length of the Hair detection elements, which the front part of the air outlet element towered over, changeable and by the user by moving the air outlet element and the support body is adjustable relative to each other, this setting can be adjusted using a suitable locking mechanism (for example with a locking screw) or thanks to a suitable breakdown of forces (e.g. like a drive with worm and rack) easy to hold on to.

So the user can choose the tool for the desired one Optimize use, for example, either for optimal bulge of the hair style close to the head or to optimal combing of longer hair.

It should be noted that the use of the inventive Tool or with the attached tool provided, for the hand use air-flowed Device is not limited to just your own hair to shape and / or to shape the user handling the device dry. The user handling the device can do so grooming someone else's hair.

If the hair detection elements, if necessary, excepted in the area of their free facing away from the carrier body Finally, have a substantially constant cross section, has the length of the user set Hair detection elements, which the front part of the air outlet element towered over, no significant impact on the exit of the air flow from the air outlet element.

If, on the other hand, the hair detection elements differ from one another Support body up to its free end facing away from it Have a tapering cross-section in the direction of the longitudinal axis, the air flow emerges from the air outlet element not only through the air outlet openings, but also also through the openings for the hair detection elements in the free space. Because the variable Cross section of the hair detection elements in a variable way fills the respective passage openings, it is the user possible, simultaneously with the adjustment of the length of the hair detection elements also the entire air flow adjust the air outlet element. Can in the longitudinal direction the cross section of the hair detection elements as desired vary, for example, the hair detection elements conical, frusto-conical or spindle-shaped with double-curved rounded Side surface be formed.

In a training example of the mechanism mentioned this mechanism comprises two functional parts a rack, on the other hand either a pinion or a worm, wherein a rotation of the pinion by the longitudinal axis of the orthogonal pinion axis or the worm a screw axis parallel to the longitudinal axis into an axial Displacement of the rack implemented parallel to the longitudinal axis becomes.

Another training example of the mechanism mentioned with two functional parts is a mechanism with groove and Spring, which is the implementation of a rotational movement of one of the Functional parts around the longitudinal axis in an axial displacement of the other functional part parallel to the longitudinal axis. The groove is a recess in one of the functional parts and the spring as a projection on the other functional part educated. As already stated, is from these two Functional parts of the one only together with the air outlet element and the other axially only together with the carrier body slidable while of these two functional parts one only rotatable about the longitudinal axis and the other only is axially displaceable. Together with another functional part, which is used to attach the tool to the device and as a separate body or as part of another Functional part can be formed, there are various Variants of this training example that differ from each other essentially through kinematic reversal and / or through other mutual positioning of the functional parts differentiate. With regard to the longitudinal axis is recommended for the groove, a pitch angle in the range from 30 ° to 60 °, for example of about 45 °.

The groove can also have one or more locking sections have a lower slope instead of a straight line with a more even one Slope to be trained. The action of external forces on the tongue migrating in the groove is in the Area of the locking sections different than in the between them Latching sections lying areas of the groove, and the corresponding dissipation of forces leads to that of Relative movement of the air outlet element brought about by external forces and the support body is difficult if the tongue is located in the region of a locking section of the groove. The user sees this as an aid to the Length of the front part of the air outlet element Set hair detection elements to predetermined values and hold.

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

The tool according to the invention basically consists of three functional parts. A first functional part remains on the device fixed immovably if the tool is intended is placed on the device. A second functional part is rotatable relative to the first functional part. A third Functional part is axial compared to the first functional part i.e. Can be moved parallel to the longitudinal axis of the tool.

1, 2 and 3 is an example of a training shown generally designated 1 tool. This Tool is designed to be used on sand air-flow device, especially on one Handheld hair dryer to be put on by a user used for hair styling and / or hair drying become. A device or a hand hair dryer of the type mentioned is known per se with and without an attached tool, for example from the catalog of Boots Co. Ltd., Nottingham (GB), "Christmas 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 section 3, on the one A plurality of air outlet openings 4 are distributed. Likewise is the tool 1 with a plurality of essentially elongated rod-shaped hair detection elements 5 provided. These hair detection elements 5 lie with their longitudinal directions 6 each other and a longitudinal axis A of Tool 1 parallel, they are on the front 3 of the Air outlet element 2 distributed and aligned from it.

The tool 1 comprises a carrier body 7 for the Hair detection elements 5. This carrier body 7 is with a essentially made of webs 8 grid or rust-like flat front section 9 provided. On this front section 9, the hair detection elements 5 are supported, whereby they from which are aligned. Between the webs 8 is the front part 9 of the carrier body 7 broken through to one to allow airflow coming from the device or hand-held hair dryer, to cross the support body 7 to the air outlet openings 4 exit tool 1.

The front part 3 of the air outlet element 2 is with Provide passage openings 10 for the hair detection elements 5. Crosses in a respective passage opening 10 a hair detection element 5, the front part 3 of the air outlet element 2 with game. The front section 3 of the air outlet element 2 and the front part 9 of the carrier body 7 from the user are relative to each other in the direction displaceable along the longitudinal axis.

In a variant, which can be seen in particular in FIG. 1 is, the game of hair detection elements 5 is in theirs respective passage opening 10 so that it is the hair detection elements 5 allows in with ease Direction of its longitudinal direction 6 relative to the air outlet element 2 to be moved, but no appreciable air flow allowed at the passage openings 10 from the tool 1 exit. Therefore, the hair detection elements 5 essentially, i.e. except in the area of the carrier body 7 facing away free end 11, with one of the respective Passage opening 10 corresponding constant cross section provided, i.e. essentially cylindrical. However, this cylindrical shape does not need to be cylindrical to be, because the hair detection elements can in Cross-section, for example, also be elliptical, as can be seen in Fig. 4, or still cruciform, etc.

In another variant, in the case of the passage openings 10 a weak air flow emerges from the tool 1 may have the hair detection elements, as it is in particular 3 shows a cross section on, in the direction of the longitudinal axis A of the support body 7th to the free end 11 of the hair detection elements facing away from it 5 tapered.

To move the front section 3 of the air outlet element 2 and the front part 9 of the carrier body 7 relative to each other in the direction of the longitudinal direction 6 of the hair detection elements 5 parallel to longitudinal axis A is a mechanism provided that can be operated by the user. Around this mechanism in its various training variants To describe it is the underlying general Concept explained.

The tool 1 according to the invention comprises in its various Training variants always three functional parts, namely a stationary first functional part, a relative one to the stationary functional part rotatable second Functional part and a relative to the stationary functional part sliding third functional part.

The mechanism mentioned generally comprises two functional parts, namely the rotatable second and the displaceable third functional part, and this mechanism is general destined to implement a rotational movement of the second functional part in an axial displacement of the third Functional part parallel to the longitudinal axis A. From the two functional parts of the mechanism is one only together with the air outlet element and the other only slidable together with the carrier body in the direction of the longitudinal axis. In addition, of the two functional parts of the mechanism one relative to the stationary functional part only rotatable and the other relative to the stationary functional part can only be moved in the direction of the longitudinal axis.

In the different training variants of the invention but there are other elements of the tool 1 that the stationary first functional part, the rotatable second Functional part and the displaceable third functional part assigned.

In particularly preferred training variants of the above Mechanism are, of the two functional parts of the Mechanism of one with a groove-shaped recess and the other with one that grips into the groove as cylindrical Provide protrusion trained spring.

For example, there is the one shown in Figs. 1-3 Training example of tool 1 the mechanism mentioned from the combination of a groove 12 and one into the groove 12 gripping cylindrical projection 13. Best visible this cylindrical projection 13 in Fig. 13, in which the same training example is presented, the level of 13 but at right angles to the plane of 3 lies.

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

The third, displaceable functional part of the tool 1 in a mutually fixed connection comprises the carrier body 7, on which the spring cooperating with the groove 12 or relevant cylindrical projection 13 is arranged, and the hair detection elements 5 supported on the carrier body 7. It is to be understood that in Fig. 3 the spring or the cylindrical Projection 13 in the center behind the track of the axis A on is the upper part of the groove 12 and therefore in the view of the connector 16 and the cylinder 19 is completely covered.

In this training example shown in Fig. 1-3 of tool 1 is also that defined above second, rotatable functional part (actuating attachment 18 with Cylinder 19) in the axial direction between two elements of the in the above-defined first, stationary functional part (Attachment attachment 14, receptacle 15, air outlet element 2 together with plug 16, funnel 17), namely between the Attachment attachment 14 and the funnel 17 held.

Finally, continue with this one shown in Figs. 1-3 Training example of tool 1, the third, displaceable functional part (carrier body 7 with spring or Projection 13 and hair detection elements 5) on the axial cylinder 19 out in the axial direction, and he is by the through the passage openings 10 of the air outlet element 2 walking hair detection elements 5 prevented from rotating.

In a variant, the receptacle 15 can be provided on the device and be part of the device itself, and in a different variant can the funnel 17 on a suitably trained The edge of the device and be attached to it can. With these two variants, tool 1 remains firmly attached to the device.

The groove 12 can, as in Fig. 2 and partially enlarged shown in Fig. 16 with respect to the longitudinal axis A the tool 1 a variable slope with one or more Have locking sections 23, in the area of the slope the groove 12 is less than outside this range. If the spring 13 is in the region of a locking section 23, the user sees this as an aid to which is the length of the hair capture elements which is the front section of the air outlet element protrudes to predetermined Set and hold values.

In a training example shown in Fig. 5 there are other elements of the tool 1 that the stationary first functional part, the rotatable second functional part and are assigned to the displaceable third functional part.

On the actuating attachment 18 is a projection 50 is provided, which is connected to the funnel 17 provided recess 51 cooperates to the funnel 17th to rotate with the actuating attachment 18.

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

In this training example shown in Fig. 5 of tool 1 is that defined in this context second, rotatable functional part (actuating attachment 18 with Cylinder 19 and funnel 17) in the axial direction between two elements of the first, stationary functional part (Attachment attachment 14, receptacle 15 and air outlet element 2 with connector 16), namely between the mounting attachment 14 and the air outlet element 2 held.

Finally, this is shown in FIG. 5 Training example of tool 1, the third, displaceable functional part (carrier body 7 with spring or Projection 13 and hair detection elements 5) on the axial cylinder 19 out in the axial direction, and he is by the through the passage openings 10 of the air outlet element 2 walking hair detection elements 5 prevented from rotating.

It should be noted in the training example shown in FIG. 5 the groove 12 that the latter - in the sense of an illustration - straight here with a steady slope is trained.

In a variant of this training example shown in FIG. 5 can with the rotatable functional part of the actuator 18, the funnel 17 and the cylinder 19 in integral construction or possibly as a result of a definitive Fastening, for example by gluing or welding be formed as a single element.

Also in this training example of FIG. 5 as in the training example of FIGS. 1-3, in another Variant, the recording 15 provided on the device and part of the Device itself, then the tool 1 on the device remains mounted. In particular, as shown in the schematic 6 shows the cylinder 19 as an integral cylindrical extension 60 of the funnel 17 and the groove 12 formed as a slot 61 in the extension 60 be, in which case the tongue 13 cooperating with the groove 12 as a projection 62 arranged radially on the outside of the carrier body 7 is formed, which also represent the web of an element 63 the actuating pin, which is guided through the groove, -lever or -knob to move the concerned Functional parts are designed to each other.

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

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

The first, stationary functional part includes each other firm connection the air outlet element 2 with the Connector 16 and the funnel 17. The connector 16 has a free End 70, which is designed to attach tool 1 to the device is, at the device one (not shown) to the end 70 of the connector 16 matching bracket is provided. For example can the tool 1 or the end 70 of the plug 16, as indicated in Fig. 7, on the device with a bayonet lock be attachable.

The second, rotatable functional part comprises one another fixed connection the actuating attachment 18 with the Groove 12 provided cylinder 19th

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

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

Finally, this is shown in FIG. 7 Training example of tool 1, the third, displaceable functional part (carrier body 7 with spring or Projection 13 and hair detection elements 5) on the axial cylinder 19 out in the axial direction, and he is by the through the passage openings 10 of the air outlet element 2 walking hair detection elements 5 prevented from rotating.

In a training example shown in Fig. 8 there are still other elements of the tool 1 that the stationary first functional part, the rotatable second functional part and assigned to the displaceable third functional part are.

The first, stationary functional part includes each other fixed connection of the funnel 17 and the cylinder 19th with the groove 12. The funnel 17 is for fastening the tool 1 trained on the device, for example, he is on the suitably designed edge of the device attachable. The funnel 17 is preferably non-rotatably on the device attached, for example with the help of a funnel 17th provided recess 81, which (analogous to the recess 51) cooperates with a projection (not shown), which is provided on the edge of the device around the funnel 17 rotatably connected to the device.

The second, rotatable functional part comprises two assemblies, namely on the one hand in a fixed connection to each other Air outlet element 2 with the plug 16, on the other hand in mutually fixed connection of the carrier body 7 with the spring or the projection 13 and the hair detection elements 5. This the two modules are essentially non-rotatable with respect to one another, but not rigidly connected to each other in the axial direction, which will be explained in the following. The connector 16 has a free end 80 that is axially fixed but rotatable Attachment of the air outlet element 2 formed on the device is, at the device one (not shown) to the end 80 of the connector 16 matching bracket is provided. For example may end 80 of connector 16 as in FIG. 8 indicated, on the device with a rotatable snap connection be attached.

The third, displaceable functional part comprises one another firm connection of the carrier body 7 with the spring or the projection 13 and the hair detection elements 5. This third, displaceable functional part thus forms one of the aforementioned assemblies, namely an axially displaceable Assembly (support body 7 with spring or projection 13 and Hair detection elements 5) while the other assembly (Air outlet element 2 with connector 16) not axially displaceable is.

In this training example shown in Fig. 8 of the tool 1 are the two assemblies of the in this context defined second, rotatable functional part (Air outlet element 2 with plug 16 on the one hand, carrier body 7 with spring or projection 13 and hair detection elements 5 on the other hand) in the axial direction by the interaction the connector 16 and the matching bracket on the device captured. The movable functional part or the axial Slidable assembly (support body 7 with spring or projection 13 and hair detection elements 5) is on the axial cylinder 19 guided in the axial direction and by the Passage openings 10 of the air outlet element 2 going Hair detection elements 5 taken in rotation, what in the above as "essentially non-rotatable assemblies" was designated.

Also in this training example shown in FIG. 8 can, as already in the schematic representation of the Fig. 6 shows the cylinder 19 as an integral cylindrical Extension 60 of the funnel 17 and the groove 12 as a slot 61 be formed in the extension 60, the then with the Groove 12 cooperating spring 13 as radially outside on the support body 7 arranged projection 62 is formed, which also can represent the web of an element 63, which is characterized by the Groove actuating pin, lever or knob trained to move the relevant functional parts to each other is.

To between the stationary and the rotating functional part allow only one relative direction of rotation, there is a corresponding one-way rotation inhibition, for example, as shown for example in Fig. 2, from a rotatable actuator 18 arranged circular Pawl track 20 arranged on the stationary funnel 17 Jack 21 interacts.

The groove 12 shown, for example, in FIG. 2 is produced with a full revolution of the cylinder exactly one complete The spring back and forth 13. The corresponding Trace of the groove 12 runs in a flat development of the jacket surface of the cylinder 19 is essentially triangular. It understands yourself with another, possibly multiple Course of the groove 12 another run of the tongue 13 with if necessary several periods over a complete rotation of the cylinder 19 can be obtained.

If desired, the tool 1 on the device, for example with the help of a provided on the attachment 14 Bayonet lock 22 (see, inter alia, Figs. 2 and 3) locked become.

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

The first, stationary functional part includes each other firm connection the air outlet element 2 with the Connector 16 and the funnel 17. The connector 16 has a free End 90, that for the rotationally fixed attachment of the air outlet element 2 is formed on the device, one (not shown) fitting to the end 90 of the connector 16 is provided. For example, the end 90 of the plug 16, as indicated in Fig. 9, on the device with a lockable Bayonet connection to be attached. Regarding the funnel 17 is its rotationally fixed attachment to the air outlet element 2 not critical, the funnel 17 can on the air outlet element 2 for example with a simpler snap connection be attached.

The second, rotatable functional part comprises one another fixed connection the actuating attachment 18 with the Groove 12 provided cylinder 19th

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

In this training example shown in Fig. 9 of tool 1 is that defined in this context second, rotatable functional part (actuating attachment 18 with Cylinder 19) in the axial direction between the stationary Funnel 17 and a suitably designed, (not shown) stationary edge of the device. This edge of the device thus plays the role of a additional element of the first, stationary functional part, and in this sense is the second, rotatable functional part analogous to the other training examples between two elements of the first, stationary functional part, here just between each element of the still Functional part (air outlet element 2 with connector 16 and Funnel 17) and the stationary device.

Finally, this is shown in FIG. 9 Training example of tool 1, the third, displaceable functional part (carrier body 7 with spring or Projection 13 and hair detection elements 5) on the axial cylinder 19 out in the axial direction, and he is by the through the passage openings 10 of the air outlet element 2 walking hair detection elements 5 prevented from rotating.

In the foregoing, in connection with Figs. 1-3 Training example of the tool 1 described that in Fig. 3 in longitudinal section with fully extended hair capture elements is shown. To complete the description 10 is the same training example again in longitudinal section, but with about half retracted Hair detection elements, and in Fig. 11 again the same Training example again in longitudinal section, but with shown completely retracted hair detection elements.

In Fig. 12, another training example of the Air outlet element 12 of the tool 1 shown in plan view. In this training example, there are passage openings on the one hand 10, in which analogously to FIG. 4 only one hair detection element 5 the front section 3 of the Air outlet element 2 in the passage opening 10 with Crosses game. On the other hand, there are also passage openings in FIG 120a and 120b shown, in which the difference 4, two hair detection elements 125a each and 125b or 125c and 125d the front part 3 of the air outlet element 1 in the passage opening 120a or 120b Cross the game - but there could also be more than two hair detection elements in a passage opening of the air outlet element be provided. This results in more flexible design options for the construction of the tool 1.

14 shows still another training example of the tool 1 shown in longitudinal section. Here serves as Drive the carrier body 7 a mechanism with a rack 140 and a pinion 141, their respective toothings interact with each other. The rack 140 extends parallel to the longitudinal axis A of the tool 1 and is with the support body 7 firmly connected, so that the movement of the Rack 140 takes place parallel to the longitudinal axis A of the tool 1. The pinion 141 has an orthogonal to the longitudinal axis A. Pinion axis 142 and one firmly connected to pinion 141 Wave 143, which is orthogonal to the axis A to outside of Tool 1 extends and allows an operator that To rotate pinion 141 and thus the rack 140 and thus also to move the carrier body 7 parallel to the longitudinal axis A.

15 shows still another training example of the tool 1 shown in longitudinal section. Here serves as Drive the carrier body 7 a mechanism with a rack 150 and a worm 151, their respective toothings interact with each other. 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 movement the rack 150 parallel to the longitudinal axis A of the tool 1 is done. The screw 151 is with its screw axis 152 coaxial with the longitudinal axis A of the tool 1, and it is firmly connected to the actuating attachment 18. This allows an operator, by rotating the actuating attachment 18 to rotate the screw 151 and thus the rack 150 and thus also the carrier body 7 parallel to the longitudinal axis A move. In a variant, the screw axis could 152 are also only parallel to the longitudinal axis A of the tool 1, without being coaxial with it.

It should also be pointed out that one according to the invention Tool 1 equivalent training to see in it is the function of the air outlet element 2 on others Transfer elements of the tool and the air outlet element 2 seemingly omitted, but in reality through Equivalent to replace. For example, the function the passage of air can be ensured that the support body 7 on its 5 carrying the hair detection elements Front section 3 of no physically existing air outlet element is covered. The flat front section of the air outlet element is then displayed from the edge of the funnel, which is both an air outlet opening and one Passage opening defines and forms that of the total number the hair detection elements is crossed. Of course is then to ensure the interaction of the Air outlet element with the support body (i.e. for exercise the function of driving in rotation or prevention the rotation) a corresponding interaction between the Carrier body and another part (attachment, Funnel, actuating attachment) to provide, for example by means of a groove provided on the funnel parallel to the axis and one provided on the carrier body and engaging in the groove Lead. There are no other equivalent solutions of this type inventive addition conceivable.
