Mit Auszugsschlauch ist hierbei ein Schlauch gemeint, der an einem Ende aus der Schlauchbox herausgezogen und wieder in selbige zurückbewegt werden kann, wobei an diesem Ende des Schlauchs typischerweise ein Nutzelement angeordnet ist, das mit dem zugeführten Fluid eine gewünschte Nutzfunktion erfüllen kann, z.B. eine Brausenfunktion.The invention relates to a pull-out hose device which comprises a hose box with a box housing, a pull-out hose held in an extendable manner on the box housing with at least one hose bend received in the box housing and a fluid connection for the pull-out hose, as well as a sanitary shower equipped with such a pull-out hose device. A pull-out hose here means a hose that can be pulled out of the hose box at one end and moved back into the same again, with a useful element being typically arranged at this end of the hose which can fulfill a desired useful function with the supplied fluid, e.g. a shower function.

Derartige Schlauchauszugsvorrichtungen sind in vielerlei Ausführungen bekannt und werden beispielsweise bei Sanitärbrausen verwendet, die eine ausziehbare Brausekopfeinheit besitzen, wie beispielsweise Küchenauszugsbrausen und Badewannen-Handbrausen. Die Schlauchbox dient mit ihrem Boxgehäuse einem vorzugsweise verdrehgesicherten Aufnehmen des oder der Schlauchbögen und ggf. zur Führung derselben, wenn der oder die Schlauchbögen U-förmig mit abhängig vom Auszugszustand des Schlauchs variabler Länge nach unten hängen. Eine optional in den Schlauchbogen drehbeweglich eingelegte Führungsgewichtsrolle kann alternativ oder zusätzlich zum Boxgehäuse die Führung des Schlauchbogens übernehmen bzw. unterstützen.Such hose pull-out devices are known in many designs and are used, for example, in sanitary showers that have a pull-out shower head unit, such as, for example, kitchen pull-out showers and bathtub hand showers. The hose box with its box housing is used to hold the hose bend or bends, preferably secured against rotation, and possibly for guiding the same when the hose bend or bends hang down in a U-shape with a variable length depending on the extension of the hose. As an alternative or in addition to the box housing, a guide weight roller that is optionally rotatably inserted into the hose bend can take over or support the guiding of the hose bend.

Eine Auszugsschlauchvorrichtung dieser Art ist beispielsweise in der Offenlegungsschrift DE 10 2015 226 412 A1 offenbart. In einem dort gezeigten Anwendungsfall für eine Küchenauszugsbrause ist der Auszugsschlauch austrittsseitig an eine Brausekopfeinheit und eintrittsseitig an einen Auslass einer entsprechenden Küchenspülenarmatur, wie einen Einhebelmischer, angekoppelt. Das Boxgehäuse ist in einem Spülenunterbau angeordnet und an einer entsprechenden Unterbauwandung montiert.A pull-out hose device of this type is for example in the laid-open specification DE 10 2015 226 412 A1 disclosed. In an application for a kitchen pull-out shower shown there, the pull-out hose is coupled on the outlet side to a shower head unit and on the inlet side to an outlet of a corresponding kitchen sink fitting, such as a single-lever mixer. The box housing is arranged in a sink substructure and mounted on a corresponding substructure wall.

Die Gebrauchsmusterschrift DE 20 2005 019 492 U1 offenbart eine Sanitärbrause mit einer weiteren derartigen Auszugsschlauchvorrichtung, wobei dort ein ausziehbarer Duschschlauch an seinem fluideintrittsseitigen Ende mit einer Gewindekupplung an einen im Boxgehäuse angebohrten Kanal angeschlossen, der seinerseits über eine entsprechende Anschlusskupplung an einen Einlass des Boxgehäuses zum Anschluss an eine Wasserzufuhr angeschlossen ist. Alternativ ist der Duschschlauch eintrittsseitig durch eine Öffnung im Boxgehäuse hindurchgeführt und mit einer Gewindekupplung an einen Wasserleitungsanschluss außerhalb des Boxgehäuses angeschlossen.The utility model DE 20 2005 019 492 U1 discloses a sanitary shower with a further such pull-out hose device, there being an pull-out Shower hose connected at its fluid inlet end with a threaded coupling to a channel drilled into the box housing, which in turn is connected to an inlet of the box housing for connection to a water supply via a corresponding connection coupling. Alternatively, the shower hose is passed through an opening in the box housing on the inlet side and connected to a water line connection outside the box housing with a threaded coupling.

Bei einer in der Patentschrift AT 193 320 offenbarten weiteren Auszugsschlauchvorrichtung dieser Art ist das Boxgehäuse aus einem Tragteil, einem mittels eines Steckverschlusses am Tragteil befestigten Mantel und einem auf den Mantel aufgesetzten Oberteil gebildet, auf dessen Oberseite ein Mischventil angeordnet ist, an dessen Unterseite eine Kaltwasserleitung, eine Warmwasserleitung und der Auszugsschlauch angeschlossen sind. Die Kaltwasserleitung und die Warmwasserleitung sind von einer jeweils zugehörigen Öffnung im Tragteil im Boxgehäuse nach oben bis zur Unterseite des Mischventils geführt.At one in the patent AT 193 320 disclosed further pull-out hose device of this type, the box housing is formed from a support part, a jacket attached to the support part by means of a plug-in closure and an upper part placed on the jacket, on the top of which a mixing valve is arranged, on the underside of which a cold water line, a hot water line and the pull-out hose are connected . The cold water pipe and the hot water pipe are led upwards from a respective opening in the support part in the box housing to the underside of the mixing valve.

In der älteren deutschen Patentanmeldung 10 2017 200 327 ist eine weitere Auszugsschlauchvorrichtung dieser Art beschrieben, bei welcher der Auszugsschlauch mehrere nach unten hängende Schlauchbögen besitzt, die in der Schlauchbox verdrehgesichert aufgenommen sind. In die Schlauchbögen ist jeweils eine Führungsgewichtsrolle mit translatorisch beweglicher Drehachse drehbeweglich einlegbar. In einem oberen Boxbereich weist die Schlauchbox wenigstens ein Schlauchumlenkelement zur Schlauchumlenkung jeweils zwischen zwei der nach unten hängenden Schlauchbögen auf, z.B. in Form eines an der Schlauchbox unbewegt angeordneten Gleitbogenelements. In die Schlauchbox kann ein Fluideinlassanschluss für den Auszugsschlauch integriert sein, z.B. in Form eines in der oberen Hälfte der Box außen an der Schmalseite angeordneten vertikalen Einlassanschlussrohres, das an einem unteren Ende einen üblichen Einlassanschlussstutzen aufweist und am oberen Ende in die Schlauchbox mündet und dort mit einem U-Bogen in einen Schlauchanschluss übergeht, an den der Auszugsschlauch mit seinem eintrittsseitigen Ende von unten angekoppelt ist.In the older German patent application 10 2017 200 327 Another pull-out hose device of this type is described, in which the pull-out hose has several downwardly hanging hose bends which are held in the hose box in a manner secured against rotation. A guide weight roller with a translationally movable axis of rotation can be rotatably inserted into the tube bends. In an upper box area, the hose box has at least one hose deflection element for hose deflection between two of the downwardly hanging hose bends, for example in the form of a sliding bend element arranged immovably on the hose box. A fluid inlet connection for the pull-out hose can be integrated into the hose box, e.g. in the form of a vertical inlet connection pipe which is arranged in the upper half of the box on the outside of the narrow side and which has a conventional inlet connection piece at a lower end and opens into the hose box at the upper end and there with it a U-bend merges into a hose connection to which the pull-out hose is coupled with its inlet-side end from below.

Der Erfindung liegt als technisches Problem die Bereitstellung einer Auszugsschlauchvorrichtung der eingangs genannten Art, die gegenüber dem oben erwähnten Stand der Technik neuartige, vorteilhafte Funktionalitäten insbesondere hinsichtlich des Fluidanschlusses für den Auszugsschlauch besitzt, sowie einer damit ausgerüsteten Sanitärbrause zugrunde.A technical problem of the invention is the provision of a pull-out hose device of the type mentioned at the beginning which, compared to the above-mentioned prior art, has novel, advantageous functionalities, in particular with regard to the fluid connection for the pull-out hose, as well as a sanitary shower equipped with it.

Die Erfindung löst dieses Problem durch die Bereitstellung einer Auszugsschlauchvorrichtung mit den Merkmalen des Anspruchs 1 sowie einer Sanitärbrause mit den Merkmalen des Anspruchs 10.The invention solves this problem by providing a pull-out hose device with the features of claim 1 and a sanitary shower with the features of claim 10.

Bei der erfindungsgemäßen Auszugsschlauchvorrichtung beinhaltet die Schlauchbox einen Boxhalterahmen, an dem das Boxgehäuse in einer Montagerichtung lösbar anbringbar ist und von dem das Boxgehäuse in einer Demontagerichtung abnehmbar ist. Der Fluidanschluss weist ein erstes, am Boxgehäuse angeordnetes Anschlussteil und ein zweites, am Boxhalterahmen angeordnetes Anschlussteil auf, wobei der Auszugsschlauch mit einem Schlauchende an das erste Anschlussteil angeschlossen ist. Das erste und das zweite Anschlussteil sind in der Montagerichtung miteinander fluiddicht verbindbar und in der Demontagerichtung voneinander lösbar.In the pull-out hose device according to the invention, the hose box contains a box holding frame to which the box housing can be detachably attached in an assembly direction and from which the box housing can be removed in a dismantling direction. The fluid connection has a first connection part arranged on the box housing and a second connection part arranged on the box holding frame, the pull-out hose being connected to the first connection part with one hose end. The first and the second connection part can be connected to one another in a fluid-tight manner in the assembly direction and can be detached from one another in the disassembly direction.

Diese Eigenschaften machen es bei der erfindungsgemäßen Auszugsschlauchvorrichtung möglich, das Boxgehäuse mit dem Auszugsschlauch von dem Boxhalterahmen abzunehmen und durch diese Demontagebewegung gleichzeitig den Fluidanschluss für den Auszugsschlauch zu lösen, da zum Lösen bzw. Trennen des Fluidanschlusses das erste und das zweite Anschlussteil in der gleichen Richtung voneinander zu lösen bzw. zu trennen sind wie die Richtung, in welcher das Boxgehäuse vom Boxhalterahmen abzunehmen ist, nämlich in der besagten Demontagerichtung. Dadurch ist es nicht erforderlich, vorab den Fluidanschluss für den Auszugsschlauch zu lösen, bevor das Boxgehäuse vom Boxhalterahmen abgenommen wird. Beide Funktionen können gleichzeitig mit der gleichen Handhabungsbewegung erfolgen, d.h. durch das Abnehmen des Boxgehäuses vom Boxhalterahmen kann gleichzeitig der Fluidanschluss für den Auszugsschlauch gelöst bzw. getrennt werden. In gleicher Weise kann gleichzeitig mit einem Wiederanbringen des Boxgehäuses am Boxrahmen mit der gleichen Handhabungsbewegung der Fluidanschluss wieder hergestellt, d.h. die beiden Anschlussteile wieder miteinander verbunden werden.With the pull-out hose device according to the invention, these properties make it possible to remove the box housing with the pull-out hose from the box holding frame and at the same time to release the fluid connection for the pull-out hose through this dismantling movement, since the first and second connection parts in the same direction to release or disconnect the fluid connection to be solved or separated from each other like the direction in which the box housing is to be removed from the box holding frame, namely in the said dismantling direction. As a result, it is not necessary to first loosen the fluid connection for the pull-out hose before the box housing is removed from the box holding frame. Both functions can take place simultaneously with the same handling movement, i.e. By removing the box housing from the box holding frame, the fluid connection for the pull-out hose can be released or disconnected at the same time. In the same way, the fluid connection can be re-established at the same time as the box housing is reattached to the box frame with the same handling movement, i.e. the two connecting parts are connected to each other again.

Der Boxhalterahmen kann vorteilhaft dazu genutzt werden, die Schlauchbox an einem gewünschten Einsatzort anzubringen, z.B. im Fall einer Auszugsschlauchvorrichtung für eine ausziehbare Badewannen-Handbrause durch Anbringen des Boxhalterahmens an einer Wannenverkleidung oder einem angrenzenden Wandbereich eines Badezimmers. Indem das Boxgehäuse lösbar am Boxhalterahmen angebracht ist, kann es von diesem z.B. für Wartungszwecke abgenommen werden, ohne dass dazu der Boxhalterahmen selbst demontiert bzw. dessen Befestigung z.B. an einer Wannenverkleidung, einem Küchenspülen-Unterbau oder dergleichen, gelöst werden muss. Der Boxhalterahmen kann alternativ auch von einem Teil eines Dusch- oder Badezimmer-Wandbereichs, einer Wannenverkleidung oder eines Küchenspülen-Unterbaus gebildet sein.The box holding frame can advantageously be used to attach the hose box to a desired location, for example in the case of a pull-out hose device for a pull-out bath hand shower by attaching the box holder frame to a bathtub panel or an adjacent wall area of a bathroom. Since the box housing is detachably attached to the box holder frame, it can be removed from the box holder frame, for example, for maintenance purposes, without the box holder frame itself having to be dismantled or its fastening e.g. to a tub panel, a kitchen sink substructure or the like having to be detached. The box holder frame can alternatively also be formed by part of a shower or bathroom wall area, a tub panel or a kitchen sink substructure.

In einer Weiterbildung der Erfindung weist das erste Anschlussteil einen ersten Anschlussstutzen und das zweite Anschlussteil einen zweiten Anschlussstutzen auf, wobei die beiden Anschlussstutzen ineinandersteckbar sind, d.h. der eine Anschlussstutzen kann in den anderen Anschlussstutzen eingesteckt werden. Der zweite Anschlussstutzen erstreckt sich durch eine Öffnung des Boxgehäuses parallel zur Montagerichtung in das Boxgehäuse hinein. Dies hat den Vorteil, dass im Fall einer Leckage des Fluidanschlusses austretendes Fluid im Boxgehäuse gehalten werden kann und keine Leckage außerhalb des Boxgehäuses verursacht. Denn indem sich der zweite Anschlussstutzen in das Boxgehäuse hinein erstreckt, liegt die leckagegefährdete Trennstelle zwischen den beiden Anschlussstutzen innerhalb des Boxgehäuses. Da sich der zweite Anschlussstutzen parallel zur Montagerichtung durch die Öffnung des Boxgehäuses in letzteres hineinerstreckt, kann das Ineinanderstecken der beiden Anschlussstutzen zum Herstellen des Fluidanschlusses beim Anbringen des Boxgehäuses am Boxhalterahmen durch dieses Anbringen des Boxgehäuses am Boxhalterahmen in der Montagerichtung erfolgen.In a further development of the invention, the first connection part has a first connection piece and the second connection part has a second connection piece, wherein the two connection pieces can be plugged into one another, i.e. one connection piece can be plugged into the other connection piece. The second connection piece extends through an opening in the box housing parallel to the assembly direction into the box housing. This has the advantage that in the event of a leak in the fluid connection, emerging fluid can be kept in the box housing and does not cause any leakage outside the box housing. Because as the second connection piece extends into the box housing, the separation point at risk of leakage between the two connection pieces lies within the box housing. Since the second connection piece extends parallel to the assembly direction through the opening of the box housing into the latter, the two connection pieces can be plugged into one another to establish the fluid connection when the box housing is attached to the box holding frame by attaching the box housing to the box holding frame in the assembly direction.

In entsprechenden Weiterbildungen der Erfindung ist die Montagerichtung eine Translationsrichtung oder eine Drehrichtung oder eine Schwenkrichtung, wobei die Demontagerichtung zur Montagerichtung jeweils entgegengesetzt ist. Im Fall der Translationsrichtung wird das Boxgehäuse mittels einer translatorischen Bewegung am Halterahmen angebracht, z.B. von oben, von unten oder von seitlich. Entsprechend sind dann auch das erste und das zweite Anschlussteil des Fluidanschlusses durch diese Translationsbewegung des Boxgehäuses relativ zum Boxhalterahmen miteinander fluiddicht verbindbar bzw. voneinander lösbar. Im Fall der Drehrichtung kann das Boxgehäuse durch eine Drehbewegung am Boxhalterahmen angebracht bzw. von diesem abgenommen werden, und entsprechend sind die beiden Anschlussteile des Fluidanschlusses durch diese Drehbewegung miteinander fluiddicht verbindbar bzw. wieder voneinander lösbar. Im Fall der Schwenkrichtung wird das Boxgehäuse durch eine Schwenkbewegung am Boxhalterahmen angebracht bzw. von diesem wieder abgenommen, und korrespondierend sind die beiden Anschlussteile des Fluidanschlusses durch diese Schwenkbewegung miteinander fluiddicht verbindbar bzw. wieder voneinander lösbar.In corresponding developments of the invention, the assembly direction is a translation direction or a direction of rotation or a pivoting direction, the disassembly direction being opposite to the assembly direction. In the case of the translation direction, the box housing is attached to the holding frame by means of a translational movement, for example from above, from below or from the side. Correspondingly, the first and the second connection part of the fluid connection can then also be connected to one another in a fluid-tight manner or detached from one another through this translational movement of the box housing relative to the box holding frame. In the case of the direction of rotation, the box housing can be attached to or from the box holding frame by a rotary movement are removed, and accordingly the two connection parts of the fluid connection can be connected to one another in a fluid-tight manner by this rotary movement or can be detached from one another again. In the case of the pivoting direction, the box housing is attached to or removed from the box holding frame by a pivoting movement, and the two connection parts of the fluid connection can correspondingly be connected to one another in a fluid-tight manner or released from one another again by this pivoting movement.

In einer Weiterbildung der Erfindung ist das Boxgehäuse an einer Oberseite offen und wenigstens in einem unteren Bereich fluiddicht ausgeführt, und die Montagerichtung verläuft in einer Einbaulage der Schlauchbox vertikal. Durch die fluiddichte Ausführung wenigstens seines unteren Bereichs eignet sich das Boxgehäuse als Leckfluidsammler, wenn im Fall einer Leckage z.B. des Auszugsschlauchs oder seiner endseitigen Anschlüsse Fluid im Bereich des Boxgehäuses austritt. Die offene Oberseite des Boxgehäuses kann z.B. dazu genutzt werden, dort den Auszugsschlauch mit seinem fluidaustrittsseitigen Schlauchabschnitt aus dem Boxgehäuse herauszuziehen, d.h. nach oben aus der Box heraus. Die in Einbaulage der Schlauchbox vertikale Montagerichtung ermöglicht z.B. ein Anbringen der Schlauchbox am Boxhalterahmen von oben oder von unten. Das Abnehmen des Boxgehäuses vom Boxhalterahmen kann in dieser Weiterbildung auch dazu genutzt werden, das Boxgehäuse von eventuell gesammeltem Leckagefluid zu entleeren, ohne dass dazu der Boxhalterahmen demontiert werden muss und ohne dass ein zusätzlicher Handhabungsschritt zum Lösen des Auszugsschlauchs von einem Fluidzufuhranschluss erforderlich ist.In a further development of the invention, the box housing is open on an upper side and fluid-tight at least in a lower area, and the assembly direction runs vertically in an installation position of the hose box. Due to the fluid-tight design of at least its lower area, the box housing is suitable as a leakage fluid collector if, in the event of a leak, e.g. of the pull-out hose or its end connections, fluid escapes in the area of the box housing. The open top of the box housing can e.g. can be used to pull the pull-out hose with its hose section on the fluid outlet side out of the box housing, i.e. up out of the box. The vertical installation direction in the installation position of the hose box enables e.g. attaching the hose box to the box holder frame from above or below. The removal of the box housing from the box holder frame can also be used in this development to empty the box housing of any leaked fluid that may have collected, without the box holder frame having to be dismantled and without an additional handling step to detach the pull-out hose from a fluid supply connection.

In einer Weiterbildung der Erfindung ist der wenigstens eine Schlauchbogen U-förmig nach unten hängend mit variabler Länge im Boxgehäuse aufgenommen. Das Boxgehäuse verläuft an seiner Unterseite U-förmig gebogen und/oder weist eine gegenüber seiner horizontalen Breite größere vertikale Länge auf. Dies kombiniert eine vorteilhafte, schwerkraftunterstützte Orientierung des oder der Schlauchbögen mit einer vorteilhaften Konfiguration bzw. Dimensionierung des Boxgehäuses.In a further development of the invention, the at least one hose bend is received in the box housing in a U-shaped hanging downwards with a variable length. The box housing is bent in a U-shape on its underside and / or has a greater vertical length than its horizontal width. This combines an advantageous, gravity-assisted orientation of the hose bend or bends with an advantageous configuration or dimensioning of the box housing.

In einer Weiterbildung der Erfindung weist das Boxgehäuse eine gegenüber seiner horizontalen Breite geringere horizontale Tiefe auf, und der Fluidanschluss ist an einem Schmalseitenbereich der Schlauchbox angeordnet. Dies stellt eine vorteilhafte Realisierung für das Boxgehäuse in Kombination mit dem Fluidanschluss dar, wobei diese Kombination bei Bedarf eine kompakte Bauform und insbesondere eine relativ geringe Bautiefe der Auszugsschlauchvorrichtung unterstützt.In a further development of the invention, the box housing has a smaller horizontal depth than its horizontal width, and the fluid connection is arranged on a narrow side area of the hose box. This is an advantageous implementation for the box housing in combination with the fluid connection, this combination supporting a compact design and in particular a relatively small overall depth of the pull-out hose device if required.

In einer Weiterbildung der Erfindung ist der Fluidanschluss an einem Oberseitenbereich der Schlauchbox angeordnet. Dies ist für bestimmte Anwendungen vorteilhaft, z.B. auch hinsichtlich der Zugänglichkeit des Fluidanschlusses und insbesondere von dessen am Boxhalterahmen angeordneten, zweiten Anschlussteil.In a further development of the invention, the fluid connection is arranged on an upper side area of the hose box. This is advantageous for certain applications, e.g. also with regard to the accessibility of the fluid connection and in particular of its second connection part arranged on the box holder frame.

In einer Weiterbildung der Erfindung weist der Fluidanschluss ein entgegen der zum Auszugsschlauch weisenden Richtung sicherndes Rückschlagventil auf, und/oder das zweite Anschlussteil weist ein in Richtung Auszugsschlauch sicherndes Rückschlagventil auf. Ersteres hat den Vorteil, dass durch ein solches Rückschlagventil ein Fluidrückfluss aus dem Auszugsschlauch in das zweite Anschlussteil verhindert werden kann. Beispielsweise kann dadurch bei Anwendung in einer Duschbrause verhindert werden, dass über die Brause Schmutzwasser angesaugt und über den Auszugsschlauch in das zweite Anschlussteil und von dort weiter z.B. in ein zugehöriges vorgelagertes Leitungsnetz oder dgl. gelangen kann. Das letztgenannte Rückschlagventil hat den Vorteil, dass ein unbeabsichtigtes Austreten von Fluid aus dem zweiten Anschlussteil sicher vermieden werden kann, wenn zum Trennen des Fluidanschlusses das erste Anschlussteil vom zweiten Anschlussteil gelöst wird und in einer Fluidzuführung zum zweiten Anschlussteil möglicherweise noch Fluiddruck ansteht. Dazu kann zweckmäßigerweise vorgesehen sein, dass dieses Rückschlagventil durch das Ankoppeln des ersten Anschlussteils an das zweite Anschlussteil beim Anbringen des Boxgehäuses am Boxhalterahmen selbsttätig zwangsgeöffnet wird, wobei es sich dann automatisch schließt, wenn beim Abnehmen des Boxgehäuses vom Boxhalterahmen das erste Anschlussteil vom zweiten Anschlussteil abgekoppelt wird.In a further development of the invention, the fluid connection has a non-return valve securing against the direction facing the pull-out hose, and / or the second connection part has a check valve securing in the direction of the pull-out hose. The former has the advantage that such a check valve can prevent a fluid backflow from the pull-out hose into the second connection part. For example, when used in a shower head, this can prevent dirty water from being sucked in via the shower head and into the second connection part via the pull-out hose and from there, e.g. Can get into an associated upstream line network or the like. The last-mentioned check valve has the advantage that unintentional leakage of fluid from the second connection part can be reliably avoided if the first connection part is detached from the second connection part to separate the fluid connection and fluid pressure may still be present in a fluid supply to the second connection part. For this purpose, it can expediently be provided that this check valve is automatically and automatically opened by coupling the first connection part to the second connection part when the box housing is attached to the box holding frame, whereby it then closes automatically when the first connection part is uncoupled from the second connection part when the box housing is removed from the box holding frame becomes.

In einer Weiterbildung der Erfindung weist der Fluidanschluss eine Sicherungseinrichtung auf, die das erste Anschlussteil gegen ein selbsttätiges Lösen vom zweiten Anschlussteil sichert. Damit lässt sich in einer vorteilhaften Weise ein unbeabsichtigtes Lösen des Fluidanschlusses verhindern. Die Sicherungseinrichtung kann beispielsweise derart ausgeführt sein, dass sie von einem Benutzer entsichert werden kann, um das Lösen des ersten Anschlussteils vom zweiten Anschlussteil zuzulassen.In a further development of the invention, the fluid connection has a securing device which secures the first connection part against automatic detachment from the second connection part. In this way, an unintentional loosening of the fluid connection can be prevented in an advantageous manner. The safety device can, for example, be designed in such a way that it can be unlocked by a user in order to allow the first connection part to be released from the second connection part.

In einer Weiterbildung der Erfindung weist das Boxgehäuse eine Haltebügelanordnung mit mindestens einem zwischen einer Bedienposition und einer Ruheposition klappbeweglichen Haltebügel auf, der eine lösbare Verriegelung umfasst, mit der das Anbringen des Boxgehäuses am Boxhalterahmen verriegelbar ist, wobei sich die Verriegelung durch eine Klappbewegung des Haltebügels von der Ruheposition in die Bedienposition löst und durch eine Klappbewegung des Haltebügels von der Bedienposition in die Ruheposition verriegelt. Damit kann das Boxgehäuse gegen ein einfaches Abnehmen vom Boxhalterahmen gesichert werden, und der oder die Haltebügel können das Abnehmen des Boxgehäuses vom Boxhalterahmen handhabungstechnisch erleichtern.In a further development of the invention, the box housing has a retaining bracket arrangement with at least one retaining bracket which can be folded between an operating position and a rest position and which comprises a releasable lock with which the attachment of the box housing to the box holding frame can be locked, the locking being moved by a folding movement of the retaining bracket from the rest position releases into the operating position and locked by a folding movement of the retaining bracket from the operating position into the rest position. The box housing can thus be secured against being simply removed from the box holding frame, and the holding bracket (s) can facilitate the removal of the box housing from the box holding frame in terms of handling.

Die erfindungsgemäße Sanitärbrause ist mit einer erfindungsgemäßen Auszugsschlauchvorrichtung sowie mit einer Brausekopfeinheit ausgerüstet, die einen Brauseaustrittsteil und einen Brausegriffteil beinhaltet. Die Brausekopfeinheit ist an einem Fluideintritt mit einem Fluidaustritt des Auszugsschlauchs verbunden, und die Schlauchbox weist eine Halterung zum abnehmbaren Halten der Brausekopfeinheit auf. Durch die Verwendung der erfindungsgemäßen Auszugsschlauchvorrichtung besitzt die Sanitärbrause die für diese Auszugsschlauchvorrichtung genannten Eigenschaften und Vorteile. Zudem dient die Schlauchbox als Halterung für die Brausekopfeinheit. Vorzugsweise befindet sich diese Halterung am Boxgehäuse der Schlauchbox. In diesem Fall kann das Boxgehäuse samt Auszugsschlauch und Brausekopfeinheit vom Boxhalterahmen abgenommen werden.The sanitary shower according to the invention is equipped with a pull-out hose device according to the invention and with a shower head unit which includes a shower outlet part and a shower handle part. The shower head unit is connected at a fluid inlet to a fluid outlet of the pull-out hose, and the hose box has a holder for detachably holding the shower head unit. By using the pull-out hose device according to the invention, the sanitary shower has the properties and advantages mentioned for this pull-out hose device. The hose box also serves as a holder for the shower head unit. This holder is preferably located on the box housing of the hose box. In this case the box housing together with the pull-out hose and shower head unit can be removed from the box holding frame.

Die in den Figuren dargestellte Brause beinhaltet eine Auszugsschlauchvorrichtung, die eine Schlauchbox 1 mit einem Boxhalterahmen 2 und einem Boxgehäuse 3 umfasst, das an dem Boxhalterahmen 2 in einer Montagerichtung M lösbar anbringbar ist und in einer Demontagerichtung D von dem Boxhalterahmen 2 abnehmbar ist. Am Boxgehäuse 3 ist ein Auszugsschlauch 5 ausziehbar gehalten. Der Auszugsschlauch 5 umfasst wenigstens einen im Boxgehäuse 3 aufgenommenen Schlauchbogen 5a. Im gezeigten Ausführungsbeispiel umfasst der Auszugsschlauch 5 zwei im Boxgehäuse 3 aufgenommene Schlauchbögen 5a, 5b, in alternativen Ausführungen umfasst er nur einen oder drei oder mehr Schlauchbögen, die im Boxgehäuse 3 aufgenommen sind.The shower shown in the figures contains a pull-out hose device which comprises a hose box 1 with a box holding frame 2 and a box housing 3 which can be detachably attached to the box holding frame 2 in an assembly direction M and detachable from the box holding frame 2 in a disassembly direction D. A pull-out hose 5 is held on the box housing 3 so that it can be pulled out. The pull-out hose 5 comprises at least one hose bend 5 a received in the box housing 3. In the exemplary embodiment shown, the pull-out hose 5 comprises two hose bends 5 a, 5 b received in the box housing 3; in alternative embodiments, it comprises only one or three or more hose bends that are received in the box housing 3.

Die Auszugsschlauchvorrichtung umfasst einen Fluidanschluss 4 für den Auszugsschlauch 5, wobei der Fluidanschluss 4 ein erstes, am Boxgehäuse 3 angeordnetes Anschlussteil 4a und ein zweites, am Boxhalterahmen 2 angeordnetes Anschlussteil 4b aufweist. An das erste Anschlussteil 4a ist der Auszugsschlauch 5 mit einem Schlauchende 6 angeschlossen. Das erste und das zweite Anschlussteil 4a, 4b sind in der Montagerichtung M miteinander fluiddicht verbindbar und in der Demontagerichtung D voneinander lösbar. Wie bereits oben erwähnt, kann dadurch mit dem Abnehmen des Boxgehäuses 3 vom Boxhalterahmen 2 gleichzeitig der Fluidanschluss 4 für den Auszugsschlauch 5 gelöst bzw. getrennt werden bzw. mit dem Wiederanbringen des Boxgehäuses 3 am Boxhalterahmen 2 gleichzeitig der Fluidanschluss 4 wieder hergestellt werden. Für die lösbare Verbindung der beiden Anschlussteile 4a, 4b sind beliebige Verbindungsmittel verwendbar, wie sie dem Fachmann zur Herstellung derartiger Fluidanschlussverbindungen an sich bekannt sind, u.a. Steckverbindungsmittel, Schraubverbindungsmittel und Kombinationen hiervon.The pull-out hose device comprises a fluid connection 4 for the pull-out hose 5, the fluid connection 4 being a first one arranged on the box housing 3 Connection part 4a and a second connection part 4b arranged on the box holding frame 2. The pull-out hose 5 is connected with a hose end 6 to the first connection part 4a. The first and second connection parts 4a, 4b can be connected to one another in a fluid-tight manner in the assembly direction M and can be detached from one another in the disassembly direction D. As already mentioned above, when the box housing 3 is removed from the box holder frame 2, the fluid connection 4 for the pull-out hose 5 can be released or disconnected at the same time, or the fluid connection 4 can be restored at the same time when the box housing 3 is reattached to the box holder frame 2. For the detachable connection of the two connection parts 4a, 4b, any connection means can be used, such as are known per se to the person skilled in the art for producing such fluid connection connections, including plug connection means, screw connection means and combinations thereof.

Im gezeigten Ausführungsbeispiel ist die Montagerichtung M eine Translationsrichtung. In alternativen Ausführungen ist die Montagerichtung eine Drehrichtung oder eine Schwenkrichtung. Die Demontagerichtung D ist im gezeigten Ausführungsbeispiel zur Montagerichtung M entgegengesetzt. In alternativen Ausführungen ist dies nicht der Fall, beispielsweise kann die Demontagerichtung schräg zur Montagerichtung verlaufen, oder es können die Montagerichtung eine Translationsrichtung und die Demontagerichtung eine Drehrichtung oder Schwenkrichtung sein oder die Montagerichtung eine Drehrichtung oder Schwenkrichtung und die Demontagerichtung eine Translationsrichtung. Im gezeigten Ausführungsbeispiel sind die Montagerichtung M und die Demontagerichtung D parallel zu einer Längsachse L der Auszugsschlauchvorrichtung, in alternativen Ausführungen ist dies nicht der Fall, beispielsweise kann in solchen Ausführungen die Montagerichtung und/oder die Demontagerichtung schräg oder senkrecht zur Längsachse der Auszugsschlauchvorrichtung verlaufen. Im gezeigten Beispiel ist die Auszugsschlauchvorrichtung für eine vertikale Montage und Demontage eingerichtet, d.h. die Montagerichtung M und die Demontagerichtung D verlaufen jeweils in einer vertikalen Richtung, z.B. die Montagerichtung M nach unten und die Demontagerichtung D nach oben. In alternativen Ausführungen ist dies nicht der Fall, beispielsweise kann in solchen Ausführungen die Montagerichtung und/oder die Demontagerichtung horizontal oder schräg zur Horizontalen verlaufen.In the exemplary embodiment shown, the mounting direction M is a translation direction. In alternative embodiments, the mounting direction is a direction of rotation or a pivoting direction. The disassembly direction D is opposite to the assembly direction M in the embodiment shown. In alternative designs, this is not the case, for example the dismantling direction can run obliquely to the assembly direction, or the assembly direction can be a translation direction and the dismantling direction can be a direction of rotation or pivoting direction or the assembly direction can be a direction of rotation or pivoting direction and the dismantling direction a translation direction. In the exemplary embodiment shown, the assembly direction M and the disassembly direction D are parallel to a longitudinal axis L of the pull-out hose device; in alternative versions this is not the case, for example in such versions the assembly direction and / or the disassembly direction can run obliquely or perpendicular to the longitudinal axis of the pull-out hose device. In the example shown, the pull-out hose device is set up for vertical assembly and disassembly, ie the assembly direction M and the disassembly direction D each run in a vertical direction, for example the assembly direction M downwards and the disassembly direction D upwards. In alternative designs, this is not the case, for example, in such designs, the assembly direction and / or the disassembly direction can run horizontally or at an angle to the horizontal.

In entsprechenden Ausführungsformen weist das erste Anschlussteil 4a einen ersten Anschlussstutzen 7a und das zweite Anschlussteil 4b einen zweiten Anschlussstutzen 7b auf, wobei die beiden Anschlussstutzen 7a, 7b ineinandersteckbar sind und sich der zweite Anschlussstutzen 7b durch eine Öffnung 8 des Boxgehäuses 3 hindurch parallel zur Montagerichtung M in das Boxgehäuse 3 hinein erstreckt, wie dies beim gezeigten Ausführungsbeispiel der Fall ist. Dadurch lässt sich erreichen, dass die Verbindungs- bzw. Trennstelle zwischen den beiden Anschlussstutzen 4a, 4b im Boxgehäuse 3 und nicht außerhalb des Boxgehäuses 3 zu liegen kommt. Dies hat den Vorteil, dass etwaiges Leckagefluid, das in einem Leckagefall an dieser Verbindungs- bzw. Trennstelle unabsichtlich austritt, im Boxgehäuse 3 gehalten und gesammelt werden kann, so dass es nicht in den Außenraum außerhalb des Boxgehäuses 3 gelangt.In corresponding embodiments, the first connection part 4a has a first connection piece 7a and the second connection part 4b has a second connection piece 7b, the two connection pieces 7a, 7b being able to be plugged into one another and the second connection piece 7b extending through an opening 8 of the box housing 3 parallel to the assembly direction M. extends into the box housing 3, as is the case in the embodiment shown. It can thereby be achieved that the connection or separation point between the two connecting pieces 4a, 4b comes to lie in the box housing 3 and not outside the box housing 3. This has the advantage that any leakage fluid that unintentionally escapes at this connection or separation point in the event of a leak can be held and collected in the box housing 3 so that it does not get into the outer space outside the box housing 3.

In entsprechenden Ausführungen dient das zweite Anschlussteil 4b mit einem unterseitigen Einlassanschlussstutzen 23 für den üblichen und daher hier nicht näher gezeigten Anschluss an eine Fluid- bzw. Wasserversorgung. Das Fluid bzw. Wasser tritt in diesem Fall am herausziehbaren Ende des Auszugsschlauchs 5 aus diesem aus. Alternativ kann die umgekehrte Fluidströmungsrichtung vorgesehen sein, d.h. das Fluid tritt dann am herausziehbaren Ende des Auszugsschlauchs 5 in diesen ein und aus dem zweiten Anschlussteil 4b aus.In corresponding embodiments, the second connection part 4b with an inlet connection piece 23 on the underside is used for the usual connection to a fluid or water supply, which is therefore not shown in detail here. In this case, the fluid or water exits at the pull-out end of the pull-out hose 5. Alternatively, the reverse fluid flow direction can be provided, i. the fluid then enters the pull-out hose 5 at its pull-out end and exits the second connection part 4b.

In entsprechenden Ausführungsformen der Auszugsschlauchvorrichtung ist, wie im gezeigten Beispiel, das Boxgehäuse 3 an einer Oberseite 3a offen und wenigstens in einem unteren Bereich 3b fluiddicht ausgeführt, wobei die Montagerichtung M in einer Einbaulage der Schlauchbox 1 vertikal verläuft. Dadurch kann Fluid, das aufgrund einer Leckage oder als Spritzwasser oder aus anderem Grund in das Boxgehäuse 3 gelangt, im Boxgehäuse 3 mit seinem fluiddichten unteren Bereich 3b gesammelt werden. Die offene Oberseite kann dazu genutzt werden, dort das herausziehbare Ende des Auszugsschlauchs 5 anzuordnen, d.h. den Auszugsschlauch 5 nach oben aus der Schlauchbox 1 herausziehen zu können. Optional kann die offene Oberseite 3a des Boxgehäuses 3 wie im gezeigten Beispiel durch eine abnehmbare Abdeckrosette 9 abgedeckt sein. In alternativen Ausführungen ist der Auszugsschlauch an einer anderen Seite der Schlauchbox aus dieser herausziehbar, z.B. unten oder seitlich. Optional kann das Boxgehäuse 3 wie gezeigt mit einer Verstärkungsrippenstruktur 24 versehen sein. Das kann die Stabilität des Boxgehäuses 3 fördern und eine Fertigung desselben mit relativ geringem Gewicht begünstigen.In corresponding embodiments of the pull-out hose device, as in the example shown, the box housing 3 is open on an upper side 3a and fluid-tight at least in a lower area 3b, the mounting direction M running vertically in an installation position of the hose box 1. As a result, fluid which gets into the box housing 3 due to a leak or as splash water or for any other reason can be collected in the box housing 3 with its fluid-tight lower region 3b. The open upper side can be used to arrange the pull-out end of the pull-out hose 5 there, ie to be able to pull the pull-out hose 5 upwards out of the hose box 1. Optionally, the open top 3 a of the box housing 3 can be covered by a removable cover rosette 9, as in the example shown. In alternative embodiments, the pull-out hose can be pulled out of the hose box on another side of the box, for example below or to the side. Optionally, the box housing 3 can be provided with a reinforcing rib structure 24 as shown. This can promote the stability of the box housing 3 and facilitate its manufacture with a relatively low weight.

In entsprechenden Ausführungsformen der Auszugsschlauchvorrichtung ist, wie im gezeigten Beispiel, der wenigstens eine Schlauchbogen 5a U-förmig nach unten hängend mit variabler Länge im Boxgehäuse 3 aufgenommen, wobei das Boxgehäuse 3 an seiner Unterseite U-förmig gebogen verläuft und/oder das Boxgehäuse 3 eine gegenüber seiner horizontalen Breite HB größere vertikale Länge VL aufweist. Dies lässt eine entsprechend große Länge für den oder die nach unten hängenden Schlauchbögen 5a, 5b im Boxgehäuse 3 zu und fördert eine kompakte Bauweise der Schlauchbox 1. In alternativen Ausführungen ist der wenigstens eine Schlauchbogen in anderer Lage, z.B. horizontal, mit variabler Länge im Boxgehäuse aufgenommen, oder das Boxgehäuse verläuft an seiner Unterseite nicht U-förmig gebogen, sondern z.B. in einer eckigen bzw. rechteckigen Kontur, oder das Boxgehäuse besitzt eine gegenüber seiner horizontalen Breite kleinere vertikale Länge.In corresponding embodiments of the pull-out hose device, as in the example shown, the at least one hose bend 5a is accommodated in a U-shaped hanging downwards with a variable length in the box housing 3, the box housing 3 extending in a U-shape on its underside and / or the box housing 3 being a compared to its horizontal width H B has greater vertical length V L. This allows a correspondingly large length for the downwardly hanging hose bend or bends 5a, 5b in the box housing 3 and promotes a compact design of the hose box 1. In alternative designs, the at least one hose bend is in a different position, e.g. horizontal, with a variable length in the box housing added, or the box housing is not bent U-shaped on its underside, but for example in an angular or rectangular contour, or the box housing has a smaller vertical length compared to its horizontal width.

In entsprechenden Ausführungsformen der Auszugsschlauchvorrichtung weist, wie beim gezeigten Beispiel, das Boxgehäuse 3 eine gegenüber seiner horizontalen Breite HB geringere horizontale Tiefe HT auf, und der Fluidanschluss 4 ist an einem Schmalseitenbereich 3c der Schlauchbox 1 bzw. des Boxgehäuses 3 angeordnet. Dies fördert ein verdrehgesichertes Aufnehmen des oder der Schlauchbögen 5a, 5b im Boxgehäuse 3 und ein platzsparendes Anordnen des Fluidanschlusses 4. In alternativen Ausführungen besitzt das Boxgehäuse eine gegenüber seiner horizontalen Breite größere horizontale Tiefe und/oder der Fluidanschluss ist an einem Breitseitenbereich der Schlauchbox angeordnet.In corresponding embodiments of the pull-out hose device, as in the example shown, the box housing 3 has a horizontal depth H T that is smaller than its horizontal width H B , and the fluid connection 4 is arranged on a narrow side area 3c of the hose box 1 or the box housing 3. This promotes a non-rotatable accommodation of the hose bend or bends 5a, 5b in the box housing 3 and a space-saving arrangement of the fluid connection 4. In alternative versions, the box housing has a greater horizontal depth than its horizontal width and / or the fluid connection is arranged on a broad side area of the hose box.

In entsprechenden Ausführungsformen der Auszugsschlauchvorrichtung ist der Fluidanschluss 4 wie beim gezeigten Beispiel in einem Oberseitenbereich 1a der Schlauchbox 1 angeordnet. Dies kann bei entsprechenden Anwendungsfällen günstig sein, z.B. hinsichtlich Zugänglichkeit des Fluidanschlusses 4 und/oder hinsichtlich eines einfachen Ankoppelns des Fluidanschlusses 4 an eine Fluidversorgung. In alternativen Ausführungen ist der Fluidanschluss in einem mittleren oder unteren Bereich der Schlauchbox angeordnet.In corresponding embodiments of the pull-out hose device, the fluid connection 4 is arranged in an upper side area 1 a of the hose box 1, as in the example shown. This can be beneficial in corresponding applications, for example with regard to the accessibility of the fluid connection 4 and / or with regard to simple coupling of the fluid connection 4 to a fluid supply. In alternative embodiments, the fluid connection is arranged in a middle or lower area of the hose box.

In entsprechenden Ausführungsformen der Auszugsschlauchvorrichtung weist wie beim gezeigten Beispiel der Fluidanschluss 4 ein entgegen der Richtung zum Auszugsschlauch 5 sicherndes Rückschlagventil 10 auf. Dadurch kann z.B. vermieden werden, dass Schmutzwasser am ausziehbaren Ende des Auszugsschlauchs angesaugt und über den Auszugsschlauch 5 in das zweite Anschlussteil 4b und von dort weiter nach hinten in einen vorgelagerten Leitungsabschnitt gelangen kann. Zusätzlich oder alternativ kann im zweiten Anschlussteil 4b ein in Richtung zum Auszugsschlauch 5 sicherndes, nicht gezeigtes Rückschlagventil vorgesehen sein. Mit einem solchen Rückschlagventil kann verhindert werden, dass Fluid, das dem zweiten Anschlussteil 4b eintrittseitig zugeführt wird, aus dem zweiten Anschlussteil 4b austritt, wenn die beiden Anschlussteile 4a, 4b voneinander gelöst werden. Dazu ist dieses Rückschlagventil zweckmäßig so konfiguriert und angeordnet, dass es mit dem Zusammenkoppeln der beiden Anschlussteile 4a, 4b zum Herstellen des Fluidanschlusses 4 zwangsgeöffnet wird und sich dann beim Trennen der beiden Anschlussteile 4a, 4b wieder selbsttätig schließt. In weiteren alternativen Ausführungen ist kein Rückschlagventil vorgesehen.In corresponding embodiments of the pull-out hose device, as in the example shown, the fluid connection 4 has a non-return valve 10 securing against the direction of the pull-out hose 5. As a result, e.g. it is avoided that dirty water is sucked in at the pull-out end of the pull-out hose and can get through the pull-out hose 5 into the second connection part 4b and from there further backwards into an upstream line section. Additionally or alternatively, a non-return valve (not shown) that secures in the direction of the pull-out hose 5 can be provided in the second connection part 4b. Such a check valve can prevent fluid that is supplied to the second connection part 4b on the inlet side from exiting the second connection part 4b when the two connection parts 4a, 4b are detached from one another. For this purpose, this check valve is appropriately configured and arranged such that it is forcibly opened when the two connection parts 4a, 4b are coupled together to establish the fluid connection 4 and then automatically closes again when the two connection parts 4a, 4b are separated. In further alternative versions, no check valve is provided.

In entsprechenden Ausführungsformen weist der Fluidanschluss 4, wie im gezeigten Beispiel, eine Sicherungseinrichtung 11 auf, die das erste Anschlussteil 4a gegen ein selbsttätiges Lösen vom zweiten Anschlussteil 4b sichert. Hierfür sind beliebige Sicherungseinrichtungen verwendbar, wie sie dem Fachmann für ein solches Sichern zweier verbundener Anschlussteile an sich geläufig sind. Im gezeigten Ausführungsbeispiel beinhaltet die Sicherungseinrichtung 11 einen Sicherungsbügel 11a, der in einer z.B. in Fig. 6 erkennbaren Sicherungsstellung lösbar, z.B. mittels einer Schnapp- oder Klipsverbindung, am zweiten Anschlussteil 4b gehalten ist und das erste Anschlussteil 4a in Demontagerichtung D umspannt und dadurch verhindert, dass sich das erste Anschlussteil 4a in Demontagerichtung D vom zweiten Anschlussteil 4b entfernen kann. Zum Entsichern dieser Sicherung kann der Sicherungsbügel 11a vom zweiten Anschlussteil 4b gelöst werden, z.B. durch Ausrasten der erwähnten Schnapp- oder Klipsverbindung, wonach das erste Anschlussteil 4a vom zweiten Anschlussteil 4b in Demontagerichtung D abgenommen werden kann. Dabei kann der Sicherungsbügel 11a am ersten Anschlussteil 4a verbleiben. In alternativen Ausführungen verbleibt der Sicherungsbügel 12 am zweiten Anschlussteil 4b und kann zum Entsichern weggeklappt oder anderweitig dergestalt bewegt werden, dass er das erste Anschlussteil 4a nicht mehr in Demontagerichtung D umspannt, so dass das erste Anschlussteil 4a zum Lösen vom zweiten Anschlussteil 4b in Demontagerichtung D freigegeben ist.In corresponding embodiments, the fluid connection 4, as in the example shown, has a securing device 11, which secures the first connection part 4a against automatic detachment from the second connection part 4b. Any desired securing devices can be used for this, as are known to those skilled in the art for securing two connected connecting parts in this way. In the embodiment shown, the securing device 11 includes a securing bracket 11a, which is in a, for example, Fig. 6 recognizable securing position is detachable, for example by means of a snap or clip connection, is held on the second connection part 4b and spans the first connection part 4a in the disassembly direction D and thereby prevents the first connection part 4a from being able to move away in the disassembly direction D from the second connection part 4b. To unlock this safety device, the securing bracket 11a can be released from the second connection part 4b, for example by disengaging the aforementioned snap or clip connection, after which the first connection part 4a can be removed from the second connection part 4b in the disassembly direction D. The securing bracket 11a can remain on the first connection part 4a. In alternative embodiments, the securing bracket 12 remains on the second connection part 4b and can be folded away to unlock or otherwise moved in such a way that it does not have the first connection part 4a spanned more in the disassembly direction D, so that the first connection part 4a is released for detachment from the second connection part 4b in the disassembly direction D.

Die bei der gezeigten Brause, bei der es sich z.B. um eine Sanitärbrause handeln kann, verwendete Auszugsschlauchvorrichtung kann alternativ für irgendeine andere sanitäre oder nicht-sanitäre Brause oder eine andere fluidführende, einen Auszugsschlauch aufweisende Vorrichtung benutzt werden. Im gezeigten Beispiel umfasst die Brause die Auszugsschlauchvorrichtung sowie eine Brausekopfeinheit 12 mit einem Brauseaustrittsteil 13 und einem Brausegriffteil 14. Die Brausekopfeinheit 12 weist einen Fluideintritt 12a auf, an dem sie mit einem Fluidaustritt 15 des Auszugsschlauchs 5 verbunden ist. Die Schlauchbox 1 der Auszugsschlauchvorrichtung beinhaltet eine Halterung 16 zum abnehmbaren Halten der Brausekopfeinheit 12.In the case of the shower shown, which is e.g. can be a sanitary shower, the pull-out hose device used can alternatively be used for any other sanitary or non-sanitary shower or another fluid-carrying device that has a pull-out hose. In the example shown, the shower comprises the pull-out hose device and a shower head unit 12 with a shower outlet part 13 and a shower handle part 14. The shower head unit 12 has a fluid inlet 12a, at which it is connected to a fluid outlet 15 of the pull-out hose 5. The hose box 1 of the pull-out hose device contains a holder 16 for holding the shower head unit 12 detachably.

Im gezeigten Ausführungsbeispiel eignet sich die Brause beispielsweise als Badewannen-Handbrause, bei der die Auszugsschlauchvorrichtung z.B. verdeckt an der Innenseite einer zugeordneten Wannenverkleidung 17 angeordnet sein kann, wie in den Fig. 4, 5, 10 und 11 veranschaulicht. Im gezeigten Beispiel ist die Auszugsschlauchvorrichtung hierzu mit ihrem Boxhalterahmen 2 an der Wannenverkleidung 17 in einer korrespondierenden Öffnung eines Oberseitenbereichs 17a der Wannenverkleidung 17 gehalten. Dieser Oberseitenbereich 17a der Wannenverkleidung 17 kann sich beispielsweise seitlich an einen Wannenrand der Badewanne anschließen.In the exemplary embodiment shown, the shower is suitable, for example, as a bathtub hand shower, in which the pull-out hose device can be arranged, for example, in a concealed manner on the inside of an associated tub cladding 17, as in FIG Fig. 4 , 5 , 10 and 11 illustrated. In the example shown, the pull-out hose device is for this purpose held with its box holding frame 2 on the tub cladding 17 in a corresponding opening of an upper side area 17 a of the tub cladding 17. This upper side area 17a of the tub cladding 17 can, for example, laterally adjoin a tub edge of the bathtub.

Das Boxgehäuse 3 der Schlauchbox 1 kann mit seiner offenen Oberseite 3a nach oben weisend in Montagerichtung M von oben nach unten in den Boxhalterahmen 2 eingesetzt und in Demontagerichtung D von unten nach oben aus diesem herausgenommen werden, wobei im eingesetzten Zustand die offene Oberseite 3a des Boxgehäuses 3 mit der optionalen Abdeckrosette 9 abgedeckt ist. Dementsprechend kann die Brausekopfeinheit 12 zur Verwendung als Handbrause in der Badewanne nach oben aus dem Boxgehäuse 3 herausgezogen werden. Nach Gebrauch kann sie wieder in ihre Halterung 16 an der Schlauchbox 1 zurückgebracht werden.The box housing 3 of the hose box 1 can be inserted with its open top 3a pointing upwards in the assembly direction M from top to bottom in the box holder frame 2 and removed from this in the dismantling direction D from bottom to top, with the open top 3a of the box housing in the inserted state 3 is covered with the optional cover rosette 9. Accordingly, the shower head unit 12 can be pulled up out of the box housing 3 for use as a hand shower in the bathtub. After use, it can be returned to its holder 16 on the hose box 1.

Diese Rückkehrbewegung kann von einer optionalen Führungsgewichtsrollenanordnung 18 unterstützt werden, die je eine in einen jeweiligen Schlauchbogen 5a, 5b um eine Drehachse 19 drehbeweglich eingelegte Führungsgewichtsrolle 18a, 18b umfasst. Hierbei kann es sich insbesondere um eine Führungsgewichtsrollenanordnung handeln, wie sie in der erwähnten älteren deutschen Patentanmeldung 10 2017 200 327 be schrieben ist, worauf vorliegend für weitere diesbezügliche Details verwiesen werden kann. Die Führungsgewichtsrollenanordnung 18 unterstützt zusammen mit der an die Abmessung des oder der Schlauchbögen 5a, 5b angepassten Dimensionierung des Boxgehäuses 3 ein verdrehgesichertes Aufnehmen der Schlauchbögen 5a, 5b und kann zusätzlich aufgrund des Eigengewichts der Führungsgewichtsrollen 18a, 18b ein Zurückbringen der ausgezogenen Brausekopfeinheit 12 in ihre Halterung 16 unterstützen. Die Führungsgewichtsrollen 18b, 18b fungieren als lose, vertikal bewegliche Rollen, wozu ihre Drehachse 19 entsprechend vertikal beweglich in einer Vertikalführung 20 an der Innenseite des Boxgehäuses 3 geführt ist. Für die obere Schlauchumlenkung zwischen den beiden gezeigten Schlauchbögen 5a, 5b dient ein an der Schlauchbox 1 unbewegt angeordnetes Gleitbogenelement 21.This return movement can be supported by an optional guide weight roller arrangement 18, which each comprises a guide weight roller 18a, 18b inserted in a respective hose bend 5a, 5b such that it can rotate about an axis of rotation 19. This can in particular be a guide weight roller arrangement, as described in the earlier German patent application mentioned 10 2017 200 327 be is written, to which reference can be made for further details in this regard. The guide weight roller arrangement 18, together with the dimensioning of the box housing 3, which is adapted to the dimensions of the hose bend (s) 5a, 5b, supports the anti-rotation picking up of the hose bends 5a, 5b and, due to the weight of the guide weight rollers 18a, 18b, can also bring the extended shower head unit 12 back into its holder 16 support. The guide weight rollers 18b, 18b function as loose, vertically movable rollers, for which their axis of rotation 19 is guided correspondingly vertically movable in a vertical guide 20 on the inside of the box housing 3. For the upper hose deflection between the two hose bends 5a, 5b shown, a sliding bend element 21, which is arranged immovably on the hose box 1, is used.

Um das Boxgehäuse 3 ausgehend vom fertig montierten Zustand der Schlauchbox 1 aus dem Boxhalterahmen 2 zu entnehmen, nimmt der Benutzer zunächst die optionale Abdeckrosette 9 ab und zieht dann im gezeigten Beispiel das Boxgehäuse 3 nach oben aus dem Boxhalterahmen 2 heraus. Dabei verbleibt der Auszugsschlauch 5 im Boxgehäuse 3, und die Brausekopfeinheit 12 verbleibt in ihrer Halterung 16.In order to remove the box housing 3 from the box holder frame 2 starting from the fully assembled state of the hose box 1, the user first removes the optional cover rosette 9 and then pulls the box housing 3 upwards out of the box holder frame 2 in the example shown. The pull-out hose 5 remains in the box housing 3 and the shower head unit 12 remains in its holder 16.

Zum leichteren Entnehmen des Boxgehäuses 3 aus dem Boxhalterahmen 2 ist an der offenen Oberseite 3a des Boxgehäuses 3 optional eine Haltebügelanordnung mit mindestens einem oder wie gezeigt zwei Haltebügeln 22 oder alternativ mehr als zwei Haltebügeln angeordnet, die sich im montierten Zustand der Auszugsschlauchvorrichtung in einer Ruheposition befinden, z.B. wie aus Fig. 2 ersichtlich parallel zur Boxoberseite 3a abgeklappt . Zum Handhaben des Boxgehäuses 3, d.h. zum Hineinbewegen in den Boxhalterahmen 2 bzw. zum Herausnehmen aus selbigem, lassen sich die Haltebügel 22 um beispielsweise ca. 90° in eine Bedienposition hochklappen, wie z.B. in den Fig. 10 und 11 dargestellt.For easier removal of the box housing 3 from the box holding frame 2, a holding bracket arrangement with at least one or, as shown, two holding brackets 22 or alternatively more than two holding brackets, which are in a rest position when the pull-out hose device is installed, is optionally arranged on the open top 3a of the box housing 3 , e.g. like from Fig. 2 can be seen folded down parallel to the top of the box 3a. To handle the box housing 3, ie to move it into the box holder frame 2 or to remove it from the same, the holding brackets 22 can be folded up by approximately 90 ° into an operating position, for example in the Fig. 10 and 11 shown.

In entsprechenden Ausführungen kann die Haltebügelanordnung eine lösbare Verriegelung für das Anbringen des Boxgehäuses 3 am Boxhalterahmen 2 aufweisen. Dazu ist die Verriegelung in einer an sich herkömmlichen Weise so konfiguriert und angeordnet, dass sie durch die Klappbewegung des oder der Haltebügel 22 von der Ruheposition in die Bedienposition gelöst wird und durch eine Klappbewegung des oder der Haltebügel 22 von der Bedienposition in die Ruheposition verriegelt wird. Zum Herausnehmen des Boxgehäuses 3 aus dem Boxhalterahmen 2 müssen daher zunächst die Haltebügel 22 in die Bedienposition hochgeklappt werden.In corresponding embodiments, the holding bracket arrangement can have a releasable locking mechanism for attaching the box housing 3 to the box holding frame 2. For this purpose, the lock is configured and arranged in a conventional manner so that it can be moved from the rest position to by the folding movement of the retaining bracket (s) 22 the operating position is released and locked by a folding movement of the retaining bracket (s) 22 from the operating position into the rest position. To remove the box housing 3 from the box holding frame 2, the holding brackets 22 must therefore first be folded up into the operating position.

Mit dem Herausbewegen des Boxgehäuses 3 aus dem Boxhalterahmen 2 in der Demontagerichtung D wird gleichzeitig der Fluidanschluss 4 gelöst, d.h. die in diesem Beispiel gesteckte Verbindung der beiden Anschlussstutzen 7a, 7b. Das zweite Anschlussteil 4b mit dem zugehörigen zweiten Anschlussstutzen 7b verbleibt am Boxhalterahmen 2, während das erste Anschlussteil 4a mit dem ersten Anschlussstutzen 7a nach oben abgezogen wird. Das Rückschlagventil 10 verhindert das Austreten von Wasser, auch wenn das zweite Anschlussteil 4b über seinen Einlassanschlusstutzen 23 an eine Wasserversorgung angekoppelt ist und diese geöffnet ist. Ein derartiges Herausnehmen des Boxgehäuses 3 kann beispielsweise dazu genutzt werden, Wartungsarbeiten am Auszugsschlauch 5 oder den anderen Komponenten im Boxgehäuse 3 oder am zweiten Anschlussteil 4b, das dann eventuell besser zugänglich ist, vorzunehmen oder das Boxgehäuse 3 von eventuell in seinem unteren Bereich 3b gesammeltem Leckfluid bzw. Leckwasser zu entleeren.When the box housing 3 is moved out of the box holding frame 2 in the disassembly direction D, the fluid connection 4 is released at the same time, i.e. the plugged connection of the two connection pieces 7a, 7b in this example. The second connection part 4b with the associated second connection piece 7b remains on the box holder frame 2, while the first connection part 4a with the first connection piece 7a is pulled off upwards. The check valve 10 prevents water from escaping even if the second connection part 4b is coupled to a water supply via its inlet connection piece 23 and this is open. Such a removal of the box housing 3 can be used, for example, to carry out maintenance work on the pull-out hose 5 or the other components in the box housing 3 or on the second connection part 4b, which may then be more accessible, or the box housing 3 from any leakage fluid that may have collected in its lower area 3b or to drain leakage water.

Die Fig. 10 und 11 veranschaulichen die Auszugsschlauchvorrichtung im Zustand mit teilweise aus dem Boxhalterahmen 2 herausbewegten Boxgehäuse 3, wobei die Fluidverbindung 4 bereits gelöst bzw. getrennt ist, d.h. der erste Anschlussstutzen 7a bereits vollständig aus seiner Steckverbindung mit dem zweiten Anschlussstutzen 7b herausgelangt ist. Analog kann das Boxgehäuse in Montagerichtung M wieder in den Boxhalterahmen eingesetzt werden, wodurch gleichzeitig der erste Anschlussstutzen 7a wieder mit dem zweiten Anschlussstutzen 7b zusammengesteckt und damit der Fluidanschluss 4 wieder hergestellt wird.The Fig. 10 and 11 illustrate the pull-out hose device in the state with the box housing 3 partially moved out of the box holding frame 2, the fluid connection 4 already being released or disconnected, ie the first connector 7a having already completely come out of its plug-in connection with the second connector 7b. Analogously, the box housing can be reinserted into the box holding frame in the assembly direction M, whereby the first connection piece 7a is simultaneously plugged together again with the second connection piece 7b and the fluid connection 4 is thus restored.

Es versteht sich, dass die gezeigte Brause und die gezeigte Auszugsschlauchvorrichtung nicht nur für Badewannen-Handbrauseneinrichtungen geeignet sind, sondern beispielsweise auch für Küchenspüleneinrichtungen mit Auszugsbrause und andere fluidversorgende Vorrichtungen mit Auszugsschlauch. Wie die gezeigten und oben erläuterten Ausführungsbeispiele deutlich machen, stellt die Erfindung eine Auszugsschlauchvorrichtung zur Verfügung, die in sehr vorteilhafter Weise ein aus einem Boxhalterahmen herausnehmbares Schlauchboxgehäuse besitzt, an dem der Auszugsschlauch ausziehbar gehalten ist, wobei gleichzeitig mit dem Montieren bzw. Demontieren des Boxgehäuses der Fluidanschluss für den Auszugsschlauch hergestellt bzw. gelöst werden kann.It goes without saying that the shower shown and the pull-out hose device shown are not only suitable for bathtub hand-held shower devices, but also, for example, for kitchen sink devices with pull-out spray and other fluid-supplying devices with pull-out hose. As the exemplary embodiments shown and explained above make clear, the invention provides a pull-out hose device which, in a very advantageous manner, consists of a box holding frame has removable hose box housing, on which the pull-out hose is held in an extendable manner, with the fluid connection for the pull-out hose being able to be established or released at the same time as the mounting or dismounting of the box housing.
