`
`BACKGROUND OF THE INVENTION
`This invention relates to a hair styling implement adapted
`to be attached to an air outlet opening of a hair dryer, with
`a housing and with a plurality of hair pickup elements and
`an adjusting means that is movable relative to the housing.
`DISCUSSION OF THE PRIOR ART
`An implement of this type is known, for example, from
`PCI International Application WO 93/09693. This specifi
`cation describes a diffuser for a hair dryer comprising a
`diffuser body adapted to be attached to the air outlet opening
`of a hair dryer. The diffuser includes a plurality of hair
`pickup elements extending away from the diffuser body, in
`particular parallel to the direction of flow through the
`diffuser. In this arrangement, at least one of the hair pickup
`elements is mounted on the diffuser body so as to be
`movable relative to the other hair pickup elements.
`In use, the ends of the hair pickup elements of the diffuser
`attached to a hair dryer are positioned against the user's
`head, resting-at least in part-on the scalp. During use of
`the diffuser, the hair pickup elements are immersed in the
`hair such as to cause the hair to separate into individual
`strands arranging themselves between the hair pickup ele
`ments. As a result of the user subsequently moving at least
`one hair pickup element relative to the remaining elements,
`the individual strands of hairlying between the movable hair
`pickup element and the adjacent immovable hair pickup
`elements are shaped in the form of a curl, a wave or some
`other bent configuration, to be exposed to the air stream
`discharged from the diffuser.
`In consequence, the strands of hair trapped between the
`hair pickup elements and shaped by reason of the displace
`ment of the at least one hair pickup element are dried by
`means of this diffuser and worked into a curly or wavy style.
`It is known from the art to attach a diffuser or the like to
`the hair dryer by means of a bayonet-type securement
`means. To this end, a plurality of circumferentially spaced
`projections are provided in the air inlet area of the diffuser.
`Recesses registering with the projections are provided at the
`air outlet opening of the hair dryer for potential locking
`engagement with the projections on the diffuser.
`SUMMARY OF THE INVENTION
`It is an object of the present invention to provide a hair
`styling implement which affords greater ease of manipula
`tion than does the known device and ensures a safe use of the
`implement.
`This object is essentially accomplished in a hair styling
`implement of the type initially referred to in that at least one
`locking means is provided which is adapted to be located in
`at least two positions, wherein the adjusting means is
`adapted to be locked with the housing in a first position of
`the locking means. In this arrangement, the adjusting means
`may be configured, for example, as a rotary ring structure
`concentrically encompassing the outside of the housing and
`connected with at least one hair pickup element. By reason
`of the locking means it is accomplished that the adjusting
`means, that is, the rotary ring structure, is suitable for
`locking engagement with the housing of the implement for
`attaching and/or removing the hair styling implement to or
`from the air outlet opening of a hair dryer. As a result, the
`adjusting means is advantageously fixed in place with
`respect to the housing of the hair styling implement, accord
`
`2
`ingly eliminating the need to rotate the adjusting means into
`a stop position-for example, at the end of the range of
`rotation of the adjusting means-as the hair styling imple
`ment is attached or removed. The user is thus in a position
`to hold the implement by the adjusting ring, introducing the
`implement into the air outlet opening of the hair dryer in
`order to lock the bayonet-type securement means. In this
`arrangement, the hair styling implement may be configured
`as a diffuser or, alternatively, as a nozzle.
`Further, a user may set and dry the hair curl or wave
`obtained by rotation of the hair pickup elements relative to
`each other. A still further advantage of the present invention
`is that, prior to the use of the hair styling implement, all of
`the hairpickup elements connected with the adjusting means
`are adapted to be located in one position. This enables the
`implement to be used in a further manner in which the hair
`pickup elements are positioned against the user's head, a
`movement of the hair pickup elements with respect to the
`head causing the hair to be caught, to ride up between the
`hair pickup elements and to be lifted in the direction of the
`air outlet opening, thus maintaining root lift and volume in
`the user's hair.
`In a further solution, the hair styling implement of the
`type initially referred to is improved such that at least one
`locking means is provided which is adapted to be located in
`at least two positions, wherein the housing of the hair styling
`implement attached to the hair dryer is adapted to be locked
`with the hairdryer in a second position of the locking means.
`This is particularly beneficial for ensuring a safe use of the
`hair styling implement, because it is fixedly connected with
`the hair dryer, preventing an inadvertent detachment of the
`implement from the hair dryer in use.
`In use of the appliance, it is thus possible and desirable for
`a user to rotate the adjusting means relative to the housing
`of the hair styling implement. This is readily possible up to
`a stop at the housing of the implement. However, if the user
`rotates the adjusting means beyond the stop, this has the
`effect of the adjusting moving the housing relative to the hair
`dryer until the bayonet-type securement means provided
`between the housing of the hair styling implement and the
`hair dryer opens. As soon as this bayonet-type securement
`means is open, safe use of the appliance is no longer
`warranted, since this then involves the risk of the implement
`becoming accidentally detached from the hair dryer and one
`of the two parts falling to the ground. This is advantageously
`avoided in that the housing is adapted to be fixed to the hair
`dryer by means of the locking
`In a particularly advantageous and highly preferred
`embodiment, the adjusting means is locked or fixed with the
`housing in the first position of the sole locking means, while
`the housing is locked or fixed with the hair dryer in the
`second position.
`In an advantageous configuration of the present invention,
`the locking means is arranged such as to be displaceable
`substantially parallel to the direction of flow through the
`housing. This affords the advantage of ease of manipulation,
`enabling the user to actuate the locking means with one
`finger of the hand gripping the implement. Because the
`adjusting means, that is, the rotary ring structure, is custom
`arily provided at the air exit end of the hair styling
`implement, the direction of displacement of the locking
`means as herein proposed further allows an ideal combina
`tion of the two locking functions proposed in the foregoing.
`In a further configuration of the present invention, the
`locking means is guided on the outside of the housing of the
`hair styling implement. The beneficial effects thereby

`achieved include ease of assembly of the locking means on
`the housing as well as good accessibility and ease of
`handling for its user.
`Because the locking means has recesses on its rear side
`close to the housing, and the housing has corresponding
`detent cams on its outside, the locking means may be
`advantageously located in a variety of positions with respect
`to the housing.
`In a still further advantageous configuration of the present
`invention, a cavity into which the locking means extends is
`provided between the housing of the hair styling implement
`and the adjusting means. This protects the user from the
`effect of temperature, because the adjusting means to be
`gripped by the user's hand is thermally decoupled from the
`housing exposed to the hot air stream. In addition, the cavity
`offers a possibility of concealing the locking means in part.
`In a particular configuration, the locking means has at
`least one end thereof one or several detent means, in
`particular teeth, cams or the like. This affords the advantage
`of enabling the locking means to be manufactured with ease
`and as a one-piece construction, being formed, for example,
`from a plastics material.
`In another advantageous configuration of the present
`invention, the adjusting means has on its inside close to the
`housing a plurality of in particular circumferentially equi
`distant recesses. This affords equally ease of manufacture
`and assembly, in particular at a concealed location not
`visible to the user's eyes. It will be understood, of course,
`that it is within the scope of a person skilled in the art to
`arrange the detent means on the adjusting means and the
`registering recesses on the locking means.
`In a particularly advantageous configuration 6fthe present
`invention, the adjusting means, that is, the rotary ring
`structure, is provided such as to be infinitely variable with
`respect to the locking means secured to the housing. By
`virtue of the connection of the rotary ring structure with at
`least one hair pickup element or a cluster of such elements,
`the rotary ring structure is advantageously infinitely variable
`within an adjustment range predetermined by the design.
`In a still further configuration of the present invention, it
`is proposed to arrange for the detent means to lockingly
`engage with the corresponding recesses essentially in a
`radial direction with respect to the housing. As a result, a
`reliable locking engagement of the detent means within the
`recesses is accomplished with a small amount of displace
`ment of the locking means in a direction essentially parallel
`to the direction of flow through the housing.
`In a further advantageous configuration of the present
`invention, the locking means has a nose-shaped projection at
`its endpointing towards the hair dryer. Advantageously, this
`projection may be made integrally with the locking means,
`enabling the locking means to effect a second locking
`function as soon as the locking means is displaced in the
`direction of the projection.
`In a particular configuration of the present invention, the
`nose-shaped projection of the locking means is suitable for
`locking engagement with a recess at the air outlet opening of
`the hair dryer. This has the advantageous effect of enabling
`the hair styling implement to be locked in place on the hair
`dryer, the projection causing the bayonet-type securement
`means to be locked.
`Further features, advantages and application possibilities
`of the present invention will become apparent from the
`Subsequent description of embodiments illustrated in more
`detail in the accompanying drawings. It will be understood
`that any single feature and any combination of single
`
`5,715,847

`DETAILED DESCRIPTION OF EMBODEMENTS
`In the Figures, there is shown by way of example a hair
`styling implement suitable for attachment to an air outlet
`opening of a hair dryer. It will be understood that it is, of
`course, also possible and advantageous to contemplate
`another embodiment in which a hair styling implement is
`integrally formed with a hair dryer, thus providing an
`independently manipulatable hair care appliance having
`other application possibilities.
`The hair styling implement 10 is adapted to be seated
`upon the air outlet opening 12 of the hair dryer 14. In the
`process, the nose-shaped projections 16 at the air inlet end
`of the implement 10 are pushed into the recesses 18 of the
`hair dryer 14. Using a rotating motion of the hair styling
`implement 10 relative to the hairdryer 14, the projections 16
`become locked within the recesses 18, thus providing a
`bayonet-type connection.
`In order to prevent the implement 10 from detaching itself
`from the dryer 14 inadvertently, the implement 10 is pro
`vided with a locking means 20 having a projection 22
`thereon. Following insertion and rotation of the implement
`10 relative to the dryer 14, the locking means 20 can be
`displaced in opposition to the direction of flow 24. The
`projection 22 on the locking means 20 thereby blocks the
`slot 26 for insertion of the projection 16.
`A hair styling implement 10 (FIG. 2) is essentially com
`prised of a bell-shaped housing 28 into which an outer ring
`30 and an inner ring 32 are insertable, each ring being
`equipped with a cluster of hair pickup elements 31. A
`locking means 20 is provided on the outside of the housing
`28. The housing 28 is subsequently fitted into the essentially
`annular adjusting means 34.
`The inner ring 32 is clipped onto the housing 28 in such
`a manner that this assembly, following seating engagement
`of the implement 10 with a dryer, is fixedly connectable
`therewith. By contrast, the outer ring 30 is clipped onto the

`adjusting means 34 so that on actuation of the adjusting
`means 34 by a user the hair pickup elements 31 mounted on
`the outer ring 30 are rotatable relative to the hair pickup
`elements 31 mounted on the inner ring 32. It will be
`understood, of course, that it is also possible for the outer
`ring 30 to be fixedly connected with the housing 28, the
`inner ring 32 being then rotatable with the adjusting means
`34
`The locking means 20 has at one end thereof a plurality
`of tooth-shaped detent means 36. At its other endpointing in
`the direction of the hair dryer, the locking means 20 is
`provided with a nose-shaped projection 22. A recessed grip
`38 is provided on the locking means 20 on the front side
`thereof pointing in the direction of the user.
`The adjusting means 34 has on its inside a plurality of
`equidistant recesses 40 for potential engagement with the
`detent means 36 of the locking means 20.
`FIG. 3A shows a section similar to the section X-X of
`FIG.2, with only the left-hand halfillustrating schematically
`the locking means 20 and the adjusting means 34. The
`locking means 20 being shown in the upper stop position,
`the detent means 36 of the locking means 20 engage within
`the recesses 40 of the adjusting means 34.
`The adjusting means 34 configured as a ring is arranged
`at the air exit end of the housing 28. Between the housing 28
`exposed to the flow of hot air and the adjusting means 34 to
`be gripped by the user's hand, there is provided a cavity 42
`in order to thermally decouple the two aforementioned
`components. This avoids user contact with the hot areas of
`the implement. To prevent the possibility of the user's hand
`slipping from the adjusting means 34 in the direction of the
`hair dryer, a circumferential bead 44 is provided at the
`upstream end of the adjusting means 34.
`FIG. 3B is a view substantially similar to that of FIG. 3A,
`but with the cutting plane slightly offset relative to the
`representation of FIG. 3A, so that in this Figure the locking
`means 20 and the flank of the recess 40 can be recognized.
`The locking means 20 is equally shown in the upper stop
`position, so that the detent cams 48 of the housing 28 are in
`locking engagement with the corresponding recesses 50 of
`the locking means 20. The projection 22 of the locking
`means 20 is likewise outside the recess 18 in the wall 46 of
`the hair dryer. The bayonet-type securement means, not
`shown in this Figure, between the housing 28 and the wall
`46 of the hair dryer is thus not yet secured in place by the
`projection 22 of the locking means 20.
`FIGS. 4A and 4B show each the locking means 20 in a
`lower-most position in which it is in locking engagement
`with the wall 46 of the hair dryer. The detent means 36 of the
`locking means 20 are not in contact with the recesses 40 of
`the adjusting means 34. As a result, the annular adjusting
`means 34 is freely rotatable relative to the housing 28. In this
`position, a user may engage the hair to be styled in the space
`between the hair pickup elements, curling or waving it by
`55
`means of the adjusting means 34.
`FIG. 4B is a view similar to that of FIG. 4A, but in a
`different cutting plane, so that in this Figure the detent cam
`48 of the housing 28 is in locking engagement within the
`dish-shaped recess 50 of the locking means 20. The projec
`tion 22 of the locking means 20 is inserted into the recess 18
`in the wall 46 of the hair dryer.
`FIG. 5 shows a fragmentary sectional view, taken along
`the line A-A of FIG. 3A. The locking means 20 includes,
`for example, a plurality of detent means 36 resembling the
`teeth of a comb and arranged on a circular-arc segment in a
`radially outwardly extending direction. These detent means
`
`6
`36 engage within the recesses 40 on the adjusting means 34
`arranged at cooperating distances to the detent means 36. In
`the engaged position shown, a rotation of the adjusting
`means 34 relative to the locking means 20, and thus also
`relative to the housing 28, is prevented from occurring.
`FIG. 6 shows a section taken along the line B-B of FIG.
`4A. In this Figure, the detent means 36 of the locking means
`20 are shown at a radial distance relative to the recesses 40
`of the adjusting means 34. This thus enables a free and
`infinitely variable rotary motion of the adjusting means 34
`relative to the locking means 20 and thus also relative to the
`housing 28. As a result, the adjusting means 34 can be
`rotated about the housing 28 within an angle of rotation
`predetermined by the design, until a new cluster of recesses
`40 is moved up to the detent means 36 for potential locking
`engagement therewith.
`FIG.7 shows a section of the projection 22 of the locking
`means 20, taken along the line C-C of FIG. 4B. An
`L-shaped recess 18 is provided on the upper side of the wall
`46 of the hair dryer. The housing 28 is seated down on the
`upper side, locking with a hook-shaped projection 16thereof
`into the recess 18 in the manner of a bayonet-type secure
`ment means. The nose-shaped projection 22 of the locking
`means 20 is then inserted into the slot 26 of the recess 18,
`thereby locking the slot 26 against inadvertent detachment
`of the projection 16, and thus of the housing 28 of the hair
`styling implement, from the hair dryer.
