Description

Die Erfindung betrifft eine Handbrause mit einem Handgriff gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a hand shower with a handle according to the preamble of claim 1.

Handbrausen dieser Art werden vorwiegend zur Körperpflege beim Duschen oder für andere Reinigungszwecke eingesetzt. Dabei kann die am Vorderende eines Duschschlauches befestigte Handbrause per Hand so geführt werden, daß aus dem Brausekopf austretende Wasserstrahlen auf den jeweils abzuspülenden Bereich gerichtet sind. Eine sichere Führung einer derartigen Handbrause kann insbesondere dann problematisch sein, wenn ein Benutzer nasse oder seifige Hände hat und/oder wenn bei Verdrehungen der Handbrause durch einen angeschlossenen Duschschlauch torsionsbedingte Rückstellkräfte auftreten. Zur verdrehsicheren Führung von Handbrausen ist es schon vorgeschlagen worden, einen Handgriff mit mehreckigem Querschnitt vorzusehen. Bekannt sind auch der Fingergröße angepaßte Griffmulden, die generell etwa in Umfangsrichtung eines Handgriffes verlaufen und die insbesondere ein Verrutschen in Längsrichtung verhindern sollen. Es sind auch schon noppenartige oder rippenartige Oberflächenvorsprünge zur Erhöhung der Griffigkeit vorgeschlagen worden.Handheld showerheads of this type are mainly used for body care while showering or for other cleaning purposes. In this case, the attached at the front end of a shower hose hand shower can be performed by hand so that from the shower head exiting water jets are directed to each area to be rinsed. A safe guidance of such a hand shower can be particularly problematic when a user has wet or soapy hands and / or when twisting the hand shower by a connected shower hose torsional restoring forces occur. For the twist-proof leadership of handheld showerheads, it has been proposed to provide a handle with polygonal cross-section. Also known are the finger size adapted grip recesses, which generally extend approximately in the circumferential direction of a handle and in particular should prevent slippage in the longitudinal direction. They are also knob-like or rib-like surface protrusions have been proposed for increasing the grip.

Die nicht vorveröffentlichte EP-A-0891815 beschreibt eine Handbrause mit kleinen Einsatzelementen aus weichem Material. Diese stehen etwas über die Oberfläche der Handbrause hervor und dienen so zum besseren Greifen.The not pre-published EP-A-0891815 describes a hand shower with small inserts made of soft material. These stand slightly above the surface of the hand shower and thus serve for better gripping.

Die EP-A-0704252 beschreibt eine Handbrause, die gesamt von einem gummielastischen hüllenförmig umgeben ist. Möglichkeiten zur Verbesserung einer Greifbarkeit gegen Rutschen sind dort nur als Vertiefungen beschrieben.The EP-A-0704252 describes a hand shower, which is surrounded by a rubber-elastic envelope. Possibilities to improve grip against slides are described there only as depressions.

Die FR-A-2523429 und die EP-A-0724041 beschreiben jeweils Handbrausen, die aus mehreren Schalen zusammengesetzt sind. Möglichkeiten zur Verbesserung einer Greifbarkeit gegen Rutschen sind auch dort nicht beschrieben.The FR-A-2523429 and the EP-A-0724041 describe each hand shower, which are composed of several shells. Ways to improve tangibility against chutes are also not described there.

Die JP06277565A offenbart eine Handbrause mit einem Griffteil, welches einen Oberflächenbezirk an der Rückseite des Griffteils aufweist, der geriffelt ist und an dem Griff direkt einstückig angeformt ist und somit aus dem gleichen Material wie der Handgriff besteht. Diese Riffelung bzw. Profilierung dient dazu, die Handbrause besser greifen zu können.The JP06277565A discloses a hand shower with a handle portion having a surface area at the back of the handle portion, which is corrugated and is integrally formed directly on the handle and thus consists of the same material as the handle. This corrugation or profiling serves to better grip the hand shower.

Dieses Dokument entspricht dem Oberbegriff des Anspruchs 1, und wird als nächstkommenden Stand der Technik angesehen.This document corresponds to the preamble of claim 1, and is considered to be the closest prior art.

Der Erfindung liegt die Aufgabe zugrunde, eine Handbrause zu schaffen, die eine sichere Handhabung während der Benutzung ermöglicht. Insbesondere soll auch eine optisch ansprechende Handbrause geschaffen werden.The invention has for its object to provide a hand shower that allows safe handling during use. In particular, a visually appealing hand shower should be created.

Zur Lösung dieser Aufgabe schlägt die Erfindung eine Handbrause mit den Merkmalen von Anspruch 1 vor.To solve this problem, the invention proposes a hand shower with the features of claim 1.

Eine erfindungsgemässe Handbrause zeichnet sich dadurch aus, dass an mindestens einer Stelle des Handgriffs ein flächig ausgedehnter Oberflächenbezirk aus einem rutschfesten Material vorgesehen ist. Ein derartiger, hinreichend grosser Antirutschbezirk schafft die Möglichkeit, auch bei Handbrausen mit ansonsten glatten und/oder abgerundeten äusseren Oberflächen eine abrutschsichere Führung bzw. einen Halt zu gewährleisten. Vorzugsweise ist mindestens ein derartiger Oberflächenbezirk in einem Bereich mit Grifffunktion oder Greiffunktion angeordnet, also einem solchen Bereich, der bei normaler Handhabung üblicherweise von der Hand, insbesondere den Fingern, berührt oder umfangen wird. So können die günstigen Griffeigenschaften eines für den Oberflächenbezirk ausgewählten Materials für die Handbrause voll genutzt werden, ohne dass die gesamte Handbrause bzw. ihre gesamte äussere Oberfläche im Hinblick auf günstige Griffeigenschaften gestaltet sein muss.A hand shower according to the invention is characterized in that at least one point of the handle is provided with a flat surface area made of a non-slip material. Such a sufficiently large anti-slip district creates the possibility, even with hand showers with otherwise smooth and / or rounded outer surfaces a slip-resistant guide or a stop guarantee. Preferably, at least one such surface area is arranged in a region with a grip function or a gripping function, that is to say an area which, under normal handling, is usually touched or surrounded by the hand, in particular the fingers. Thus, the favorable grip properties of a material selected for the surface area for the hand shower can be fully utilized without the entire hand shower or its entire outer surface must be designed in terms of favorable grip properties.

Entsprechend der rutschhemmenden oder bremsenden Funktion der Oberflächenbezirke ist bei einer bevorzugten Weiterbildung der Erfindung vorgesehen, dass mindestens ein Oberflächenbezirk im Bereich der Handgriffunterseite der Handbrause angeordnet ist, die bei normalem Gebrauch von den Fingern eines Benutzers umgriffen und damit in besonderem Masse die Griffsicherheit bestimmt. Hierdurch lässt sich besonders wirksam die Haftung zwischen Hand und Oberflächenbezirk bzw. Handbrause verbessern. Alternativ oder zusätzlich können auch eine oder mehrere Oberflächenbezirke am Handgriffrücken oder an einer oder beiden Seiten eines Handgriffes angebracht sein. Zusätzlich ist es auch möglich, dass mindestens ein Oberflächenbezirk, insbesondere mindestens ein Rutschsicherungselement, an einem beweglich an der Handbrause angebrachten Betätigungselement zur Einstellung einer Funktion des Handgriffes angeordnet ist. So kann beispielsweise ein an dem Brausekopf angeordnetes oder diesem zugeordnetes Betätigungselement zum Umstellen zwischen verschiedenen Strahlarten auf erfindungsgemässe Weise besonders griffsicher gestaltet werden, insbesondere durch vollständiges Überziehen, um eine feinfühlige Verstellung zu ermöglichen.According to the antislip or braking function of the surface areas of a preferred embodiment of the invention, it is provided that at least one surface area in the region of the handle bottom of the hand shower is arranged, which encompasses the fingers of a user in normal use and thus determines the grip security in particular. This makes it particularly effective to improve the adhesion between the hand and surface area or hand shower. Alternatively or additionally, one or more surface areas may be attached to the handle back or to one or both sides of a handle. In addition, it is also possible for at least one surface area, in particular at least one slip-protection element, to be arranged on an actuating element movably mounted on the hand-held shower head for adjusting a function of the handle. Thus, for example, an arranged on the shower head or this associated actuator for switching between different types of spray in the inventive manner be made very secure handle, in particular by complete coating to allow a sensitive adjustment.

Die Ausdehnung mindestens eines Antirutsch-Oberflächenbezirkes ist erfindungsgemäß grösser als ca. 5 cm2 und liegt insbesondere zwischen ca. 5 cm2 und ca. 30 cm2, so dass im grossflächigen Zusammenspiel mit einer angreifenden Hand ein sicherer Rutschschutz gewährleistet ist. Ein derartiger Oberflächenbezirk kann im wesentlichen bündig mit der ihn umgebenden, ggf. glatten Oberfläche der Handbrause sein, so dass ein im wesentlichen ansatzloser Übergang zwischen rutschgesicherten und ggf. glatten Oberflächen möglich ist und die in der Regel nach gestalterischen Gesichtspunkten optimierte Oberflächenform bzw. Kontur der Handbrause im Bereich des Oberflächenbezirkes nicht unterbrochen, sondern fortgesetzt ist. Ein Antirutsch-Oberflächenbezirk kann somit gestalterisch als Teil der Gesamtform der Handbrause erscheinen, ggf. aber optisch von dieser abgesetzt sein. Insbesondere kann ein vorzugsweise nach ästhetischen Gesichtspunkten geformter, beispielsweise runder oder ovaler Oberflächenbezirk eine andere Färbung und/oder Musterung haben als die ihn umgebende Handgriffoberfläche, wodurch das Erscheinungsbild der Handbrause optisch aufgelockert werden kann.The extent of at least one anti-slip surface area is greater than about 5 cm 2 according to the invention and lies in particular between about 5 cm 2 and about 30 cm 2 , so that in the large-scale interaction with an attacking hand, a secure slip resistance is guaranteed. Such a surface area may be substantially flush with the surrounding, possibly smooth surface of the hand shower, so that a substantially seamless transition between non-slip and possibly smooth surfaces is possible and optimized usually after design aspects surface shape or contour of the Hand shower in the area of the surface area is not interrupted, but is continued. An anti-slip surface area may thus appear as part of the overall shape of the hand shower, but may be visually offset therefrom. In particular, a preferably aesthetically shaped, for example, round or oval surface area have a different color and / or pattern than the surrounding handle surface, whereby the appearance of the hand shower can be optically loosened.

Eine rutschhemmende Wirkung derartiger Oberflächenbezirke kann insbesondere dadurch gefördert werden, daß der Oberflächenbezirk eine Oberflächenrauhigkeit hat, die größer ist als die Oberflächenrauhigkeit von umgebenden Abschnitten der Handbrausenoberfläche. Alternativ oder zusätzlich kann ein Oberflächenbezirk auch makroskopisch rutschhemmend profiliert sein, wobei insbesondere eine Verteilung kleinflächiger Griffmulden vorgesehen sein kann, die bei fest zugreifender Hand die Verdrängung von Flüssigkeit zwischen Hand und Oberfläche fördern und dadurch einen großflächigen Bremskontakt ermöglichen kann. Kleinflächige Oberflächenausnehmungen, die mit Tiefen von weniger als 0,5 oder 1 mm sehr flach sein können, haben sich als sehr grifffreundlich herausgestellt.An antislip effect of such surface areas can be promoted in particular by the surface area having a surface roughness which is greater than the surface roughness of surrounding portions of the hand shower surface. Alternatively or additionally, a surface area can also be profiled macroscopically slip-resistant, in particular, a distribution of small-scale recessed grips can be provided, which promotes the displacement of liquid between the hand and surface with firmly grasping hand, thereby enabling a large-area brake contact. Small-scale surface cavities, which can be very shallow with depths of less than 0.5 or 1 mm, have proven to be very easy to handle.

Eine vorteilhafte Weiterbildung zeichnet sich dadurch aus, daß ein Oberflächenbezirk mindestens bereichsweise elastisch nachgiebig ist, so daß bei äußerem Druck im Bereich des Oberflächenbezirkes eine Anpassung der Oberflächenform an die Form der angreifenden Hand erfolgen kann. Hierdurch werden ein großflächiger Berührungskontakt und ein dauerhaft angenehmes Griffgefühl gefördert.An advantageous development is characterized in that a surface area is at least partially elastically yielding, so that at external pressure in the region of the surface area an adaptation of the surface shape to the shape of the attacking hand can be done. As a result, a large-area touch contact and a lasting pleasant feel are promoted.

Zwar können die Vorteile der Erfindung auch durch Verwendung beliebiger Materialien und/oder von Naturstoffen im Oberflächenbezirk erzielt werden. Herstellungstechnisch besonders zweckmäßig und kostengünstig ist es, wenn das Material des Oberflächenbezirkes ein rutschfester Kunststoff ist. Insbesondere können thermoplastische Kautschuke verwendet werden, wie sie beispielsweise unter der Markenbezeichnung "Santoprene R" erhältlich sind. Derartige Kunststoffe, die zur Polymergruppe der Polyolefine gehören und beispielsweise eine Zusammensetzung mit EPDM und Polypropylen haben können, zeichnen sich durch elastische und taktile Eigenschaften aus, die denen mancher Synthesekautschuke gleichen, insbesondere durch niedrige bleibende Verformung. Sie müssen jedoch nicht vulkanisiert werden, sondern können in der Regel mit allen für die Verarbeitung thermoplastischer Elastomere geeigneten Verfahren kostengünstig verarbeitet werden, beispielsweise in Spritzgusstechnik.Although the advantages of the invention can be achieved by using any materials and / or natural substances in the surface area. Manufacturing technology particularly useful and inexpensive, it is when the material of the surface area is a non-slip plastic. In particular, thermoplastic rubbers can be used, such as those available, for example, under the trade name "Santoprene R". Such plastics used to Polymer group include the polyolefins and may for example have a composition with EPDM and polypropylene, are characterized by elastic and tactile properties similar to those of some synthetic rubbers, in particular by low permanent deformation. However, they need not be vulcanized, but can generally be processed inexpensively with all suitable processes for the processing of thermoplastic elastomers, for example in injection molding.

Ein erfindungsgemässer Oberflächenbezirk ist an einem vorgefertigten, vorzugsweise weitgehend formstabilen oder selbsttragenden Rutschsicherungselement ausgebildet, das, vorzugsweise von aussen, an der Handbrause befestigbar ist. Die Wandung der Handbrause kann an den mit einem Rutschsicherungselement zu versehenden Stellen des Handgriffs ausgespart sein, so dass das Rutschsicherungselement an diesen Stellen die Wandung ersetzt. Die Herstellung und Formgebung des Oberflächenbezirkes kann unabhängig von der Herstellung der übrigen Teile der Handbrause einfach und kostengünstig erfolgen. Die Teile können in einem der jeweiligen Herstellung nachfolgenden Montageschritt miteinander verbunden werden. Die Befestigung kann mittels gesonderter, ggf. werkzeugbetätigter Befestigungsmittel, wie Schrauben oder dergleichen, erfolgen. Eine besonders einfache Montage und ggf. Demontage lässt sich bei einer bevorzugten Weiterbildung dadurch erreichen, dass ein Rutschsicherungselement werkzeuglos, also ohne Zuhilfenahme von Werkzeugen, an der Handbrause befestigbar ist. Hierzu können insbesondere an dem Rutschsicherungselement und der Handbrause zusammenwirkende Mittel bzw. Strukturen vorgesehen sein, die es ermöglichen, ein Rutschsicherungselement mit der Handbrause formschlüssig zu verrasten und/oder an der Handbrause festzuklemmen. Ein Rutschsicherungselement, das auch als Haptik-Element bezeichnet werden kann, ist als in eine Aufnahmeöffnung der Handbrause, insbesondere des Handgriffs einsetzbarer Einsatz oder als ein auf einem Haltevorsprung der Handbrause aufsetzbarer Aufsatz ausgebildet. Rutschsicherungselemente können leicht, insbesondere werkzeuglos, auswechselbar ausgebildet sein, so dass sich beispielsweise durch Abnehmen eines Rutschsicherungselementes und Ersetzen durch ein bzgl. seiner Einbaumasse identisches, aber anders gestaltetes und/oder gefärbtes Rutschsicherungselement sich die Optik der Handbrause auf einfache Weise verändern und beispielsweise der Farbgebung der Einsatzumgebung anpassen lässt. Aus Gründen der einfachen und kostengünstigen Herstellung sind Rutschsicherungselemente bevorzugt, die durch ein einteiliges Kunststoffteil, vorzugsweise ein Spritzgussteil, gebildet sind, das aus dem beschriebenen thermoplastischen Kautschukmaterial besteht. Es ist auch möglich, die Aufnahmeöffnung für ein Rutschsicherungselement gleichzeitig als Zugangsöffnung für Funktionsteile vorzusehen, die in der Handbrause, insbesondere im Brausegriff angeordnet sind. Solche Funktionsteile können beispielsweise Filter, Drosseleinrichtungen und/oder Geräuschdämpfer sein.A surface area according to the invention is formed on a prefabricated, preferably largely dimensionally stable or self-supporting slip-protection element which, preferably from the outside, can be fastened to the hand-held showerhead. The wall of the hand shower can be recessed at the points to be provided with a slip-protection element of the handle, so that the slip-protection element replaces the wall at these locations. The preparation and shaping of the surface area can be done easily and inexpensively regardless of the production of the other parts of the hand shower. The parts can be connected together in an assembly step following the respective production. The attachment can be done by means of separate, possibly tool-operated fastening means, such as screws or the like. A particularly simple assembly and possibly disassembly can be achieved in a preferred development in that a slip-protection element without tools, so without the aid of tools, is attachable to the hand shower. For this purpose, cooperating means or structures can be provided, in particular on the slip protection element and the hand shower be, which make it possible to positively lock an anti-skid element with the hand shower and / or clamp on the hand shower. A slip protection element, which can also be referred to as a haptic element, is designed as an insert which can be inserted into a receiving opening of the hand shower, in particular of the handle, or as an attachment which can be placed on a holding projection of the hand shower. Anti-skid elements can be designed to be replaceable, in particular without tools, so that, for example, by removing a slip-protection element and replacing it with a built-in cup identical but differently shaped and / or colored slip-protection element, the appearance of the hand-held showerhead can be changed in a simple manner and, for example, the color scheme customize the environment of use. For reasons of simple and cost-effective production, anti-slip elements are preferred, which are formed by a one-piece plastic part, preferably an injection-molded part, which consists of the described thermoplastic rubber material. It is also possible to provide the receiving opening for an anti-skid element at the same time as an access opening for functional parts, which are arranged in the hand shower, in particular in the shower handle. Such functional parts may be, for example, filters, throttle devices and / or noise dampers.

The described features and further features of the invention will become apparent from the following description of a preferred embodiment in conjunction with the subclaims and the drawings. In this case, the individual features can be implemented individually or in combination with one another in each case. In the drawings show:

a perspective view of the handle insert inserted at the bottom of the handle with non-slip surface.

Die Seitenansicht in Fig. 1 zeigt eine teilweise geschnitten dargestellte Handbrause 1 mit einem im Querschnitt ovalen Handgriff 2 und einem am vorderen Ende des Handgriffes ausgebildeten Brausekopf 3. Im Inneren der Handbrause führt ein Flüssigkeitskanal 4 vom hinteren, mit einem Schraubgewinde 5 zum Schlauchanschluß versehenen Handgriffende bis in den Bereich des Brausekopfes, an dessen unterem Ende Strahlaustrittsöffnungen 6 für den Wasseraustritt vorgesehen sind. Das langgestreckte, tonnenförmig nach außen gewölbte Gehäuse 7 des Handgriffes geht ansatzlos in das einstückig damit ausgebildete Brausekopfgehäuse 8 über, dessen unteres Ende eine im wesentlichen kreisförmige Öffnung bildet, in die eine gegenüber dem Brausekopf verdrehbare Strahlscheibe 9 eingesetzt, insbesondere eingeschnappt ist. Dies kann mittels eines auf der Seite des Handgriffes abragenden Betätigungshebels 10 vom Benutzer zur Verstellung zwischen verschiedenen Strahlarten gegenüber dem Brausekopfgehäuse verdreht werden. Die Gehäuseteile 7 und 8 von Handgriff und Brausekopf, die vorzugsweise aus mehreren Teilschalen zusammengesetzt sind, sind aus einem steifen, schlagfesten Kunststoffmaterial spritzgegossen. Bei der Ausführungsform bestehen die Gehäuseteile 7, 8 aus Acryl-Nitril-Butadien-Styrol, das sich in Spritzgußtechnik gut verarbeiten läßt und anschließend zur Bildung einer optisch ansprechenden, verschleißfesten, glatten und glänzend erscheindenden äußeren Oberfläche 11 verchromt wurde.The side view in Fig. 1 In the interior of the hand shower leads a liquid channel 4 from the rear, provided with a screw thread 5 to the hose connection end of the handle into the region of the shower head , At the lower end of which jet outlet openings 6 are provided for the water outlet. The elongated, barrel-shaped outwardly curved housing 7 of the handle passes without any length in the integrally formed therewith a shower head housing 8, the lower end forms a substantially circular opening into which a rotatable relative to the shower head jet disk 9 is inserted, in particular snapped. This can be rotated by means of a projecting on the side of the handle actuating lever 10 by the user for adjustment between different spray modes with respect to the showerhead housing. The housing parts 7 and 8 of the handle and shower head, which are preferably composed of a plurality of partial shells, are made of a stiff, impact-resistant plastic material injection molded. In the embodiment, the housing parts 7, 8 made of acrylonitrile-butadiene-styrene, which can be processed well by injection molding and then chromium-plated to form a visually appealing, wear-resistant, smooth and shiny erscheindenden outer surface 11.

An der auf der Seite der Strahlaustrittsöffnungen 6 liegenden Unterseite 13 des Handgriffes 2 ist in der Gehäusewand eine in Längsrichtung des Handgriffes ausgerichtete, längsovale Aufnahmeöffnung 14 ausgespart, die in das mit Versteifungs-und/oder Wasserführungswänden versehene Innere des Handgriffs führt. Die Aufnahmeöffnung 14 erstreckt sich über ca. 40 bis 60 % der Länge des Handgriffes und über ca. 80 % der in der Unteransicht (Fig. 2) erkennbaren Breite der Unterseite und liegt in dem Bereich des Handgriffes, der bei normaler Benutzung der Handbrause von den vorderen Fingergliedern eines Benutzers mit relativ großem Druck umfaßt wird.At the side of the jet outlet openings 6 lying bottom 13 of the handle 2 in the housing wall in the longitudinal direction of the handle aligned, longitudinal oval receiving opening 14 is recessed, which leads into the provided with stiffening and / or Wasserführungswänden interior of the handle. The receiving opening 14 extends over approximately 40 to 60% of the length of the handle and about 80% of the in the bottom view ( Fig. 2 ) recognizable width of the bottom and is in the range of the handle, which is included in normal use of the hand shower of the front phalanges of a user with a relatively large pressure.

In die Aufnahmeöffnung 14 ist ein in Fig. 1 im Längsschnitt, in Fig. 2 in Draufsicht und in Fig. 3 perspektivisch gezeigter Griffeinsatz 15 ohne Zuhilfenahme von Werkzeugen von außen eingesetzt und durch Rastmittel im wesentlichen formschlüssig gehaltert. Der Einsatz 15 ist ein einstückig aus einem thermoplastischen Kautschukmaterial spritzgegossenes Kunststoffteil. Es hat einen ca. 2 mm dicken, quer zur Längsrichtung des Einsatzes im wesentlichen zylindrisch gekrümmten und in Längsrichtung im wesentlichen geraden, ovalen Schalenabschnitt 16, an dessen konkav gekrümmter Innenseite 17 im Bereich eines Längsendes ein zum Ende angeschrägter Haltefinger 18 und am gegenüberliegenden Ende ein kürzerer, etwa rechtwinklig zum Ende hin gekrümmter Haltefinger 19 angeformt ist. Das thermoplastische Kautschukmaterial des schiffchenförmigen Einsatzelementes 15 hat eine im wesentlichen aus EPDM/PP bestehende Zusammensetzung. Es hat eine Shore-Härte zwischen ca. 70 und 90 A, was einerseits bei der gewählten Dicke des Schalenabschnittes 16 eine Eigensteifigkeit des Einsatzes bewirkt, die diesen bei Abwesenheit äußerer Kräfte in der in Fig. 3 gezeigten entspannten weitgehend freitragenden bzw. selbsttragenden Form hält, andererseits aber eine gewisse elastische Nachgiebigkeit des Schalenabschnittes 16 bei Einwirkung äußerer Kräfte zuläßt.In the receiving opening 14 is an in Fig. 1 in longitudinal section, in Fig. 2 in plan view and in Fig. 3 shown in perspective handle insert 15 without the aid of tools used from the outside and held by locking means substantially positive fit. The insert 15 is an integrally injection molded from a thermoplastic rubber material plastic part. It has an approximately 2 mm thick, transversely to the longitudinal direction of the insert substantially cylindrically curved and longitudinally substantially straight, oval shell portion 16, at its concavely curved inner side 17 in the region of a longitudinal end of an end tapered retaining finger 18 and at the opposite end shorter, approximately at right angles to the end curved retaining fingers 19 is formed. The thermoplastic rubber material of the ship-shaped insert member 15 has a essentially consisting of EPDM / PP composition. It has a Shore hardness between about 70 and 90 A, which causes on the one hand at the selected thickness of the shell portion 16 an inherent rigidity of the insert, which in the absence of external forces in the in Fig. 3 shown relaxed largely cantilevered or self-supporting shape holds, on the other hand, however, allows a certain elastic compliance of the shell portion 16 under the action of external forces.

Der in einem gesonderten Spritzgußprozeß unabhängig vom Gehäuse der Handbrause hergestellte Einsatz 15 wird in die Aufnahmeöffnung 14 von außen eingesetzt, indem zunächst der nach innen zum Ende hin angeschrägte vordere Randbereich 20 in den komplementär geformten vorderen Innenrandbereich 21 der Aufnahme 14 eingeschoben wird, so daß der Einsatz den zum Öffnungsinneren vorspringenden Außenbereich des Randes 21 hintergreift. Beim Einsetzen wird gleichzeitig der vordere Haltefinger 18 in eine zwischen Gehäusewänden 22, 23 des Handgriffgehäuses gebildete Ausnehmung geschoben und rastet dort ein, wobei der Einführprozeß durch die Biegsamkeit des elastischen Einsatzmaterials erleichtert wird. Anschließend wird der nach außen angeschrägte hintere Randbereich 24 des Einsatzes 15 in einen komplementär geformten, sich zur Oberfläche des Handgriffs erweiternden hinteren Randbereich 25 des Gehäuses 7 eingesetzt, bis die komplementären Flächen aufeinanderliegen. Beim Einsetzen wird der elastische Haltefinger 19 zunächst durch einen in das Innere der Aufnahmeöffnung ragenden Haltevorsprung 26 nach vorne gebogen und schnappt bei vollständig eingesetztem Einsatz 15 zurück und hintergreift den Haltevorsprung 26. Dadurch ist der Einsatz 15 verliersicher formschlüssig am Handgriffgehäuse verrastet. Der zwischen den Haltefingern 18, 19 liegende Mittelbereich 27 des Einsatzes wird durch einen an der Innenseite 17 des Einsatzes anliegenden Stützkörper 28 gegen Eindrücken abgestützt. Die beidseits des Stützkörpers 28 liegenden Bereiche zwischen den vorderen bzw. hinteren Abstützungen des Einsatzes und dem Halter sind dagegen rückseitig freigehalten und damit wegen der Elastizität des Einsatzmateriales bei entsprechendem Fingerdruck von außen um einige Zehntel Millimeter oder Millimeter elastisch nachgiebig, so daß sich die Außenkontur des Handgriffes 2 im Bereich des Einsatzes 15 begrenzt der Form einer von außen drückenden Hand anpassen kann. Wenn der als gesondertes Einsteckteil ausgebildete Stützkörper 28 aus einem elastischen Material gefertigt ist, so kann auch im Mittelbereich die Oberfläche 30 des Einsatzes bei äußerem Druck elastisch nachgeben.The made in a separate injection molding process independently of the housing of the hand shower insert 15 is inserted into the receiving opening 14 from the outside by first the inwardly towards the end beveled front edge portion 20 is inserted into the complementary shaped front inner edge portion 21 of the receptacle 14, so that the Insert behind the opening interior projecting outside of the edge 21 engages behind. When inserting the front retaining finger 18 is simultaneously pushed into a recess formed between the housing walls 22, 23 of the handle housing and snaps there, wherein the insertion process is facilitated by the flexibility of the elastic feedstock. Subsequently, the outwardly tapered rear edge portion 24 of the insert 15 is inserted into a complementarily shaped, extending to the surface of the handle rear edge portion 25 of the housing 7 until the complementary surfaces lie on one another. When inserting the elastic retaining finger 19 is first bent by a projecting into the interior of the receiving opening retaining projection 26 forward and snaps back when fully inserted insert 15 and engages behind the retaining projection 26. Thus, the insert 15 captive locked form-fitting on the handle housing. The intermediate region 27 of the insert located between the retaining fingers 18, 19 is replaced by a on the inside 17 of the Insert fitting support body 28 supported against impressions. The lying on both sides of the support body 28 between the front and rear supports of the insert and the holder are, however, the back kept free and thus resiliently resilient because of the elasticity of the feed material with appropriate finger pressure from the outside by a few tenths of a millimeter or millimeters, so that the outer contour of the Handle 2 in the area of the insert 15 limited the shape of an oppressive hand from the outside can adjust. If the support body 28 formed as a separate plug-in part is made of an elastic material, the surface 30 of the insert can yield elastically in the middle region even under external pressure.

Bei eingesetztem Griffeinsatz 15 (Fig. 1 und 2) bildet die den Haltefingern 18, 19 gegenüberliegende äußere Oberfläche 30 des Einsatzes einen bündig bzw. ansatzlos in die benachbarten Oberflächenbereiche des Gehäuses übergehenden Oberflächenbezirk, der die äußere Gestalt des Handgriffes fortführt, sich aber optisch und bzgl. seines taktilen Verhaltens sowie insbesondere bzgl. seiner Griffigkeit deutlich von der ansonsten glatten, glänzenden Oberfläche 11 des Handgriffes unterscheidet. Der ca. 20 bis 30 cm2 große, ovale Oberflächenbezirk 30 vermittelt aufgrund des gummiartigen Materials des Einsatzes und einer im Vergleich zu den glatten Umgebungsoberflächen sich rauh anfühlenden Oberfläche mit einer mittleren Rauhtiefe von ca. 10 µm ein angenehm griffiges Gefühl, ohne im unangenehmen Sinne rauh zu wirken. Der Oberflächenbezirk 30 vermittelt ein angenehmes Griffgefühl, das dem einer etwas speckigen Papieroberfläche nicht unähnlich ist. Die rutschhemmende Wirkung des nach Art einer Reibungsbremse wirkenden Oberflächenbezirkes 30 bleibt auch bei nassen und ggf. seifigen Händen weitgehend vorhanden, so daß ein mit einem derartigen Einsatz versehener Handgriff während des Duschens sicher geführt werden kann. Die rutschhemmende Wirkung wird durch kleinflächige, flache Griffmulden 31 unterstützt, die in einer optisch ansprechenden Verteilung mit angenähert sechszähliger Symmetrie über den Oberflächenbezirk 30 verteilt sind. Die kugelsegmentförmigen Vertiefungen 31 mit einer Tiefe von wenigen Zehntel Millimetern und Durchmessern von 1 bis 2 mm können nach Art von Reifenprofilen bei nassem Handgriff die Flüssigkeitsverdrängung durch die haltende Hand unterstützen und auf diese Weise die Haftung an den Fingern im Bereich des Oberflächenbezirkes 30 unterstützen. Im Gegensatz zu ebenfalls möglichen, nach außen vorstehenden Noppen oder Rippen verursachen die quasi punktförmigen Vertiefungen auch bei längerem, festem Festhalten des Handgriffes keine unangenehmen Druckstellen.When inserted handle insert 15 ( Fig. 1 and 2 ) forms the retaining fingers 18, 19 opposite outer surface 30 of the insert a flush or immaterial in the adjacent surface areas of the housing transition surface area, which continues the outer shape of the handle, but optically and with respect to its tactile behavior and in particular with respect Grip clearly different from the otherwise smooth, glossy surface 11 of the handle. The approx. 20 to 30 cm 2 large, oval surface area 30 conveys a pleasant non-slip feeling due to the rubber-like material of the insert and a surface which feels rough in comparison to the smooth surrounding surfaces with an average surface roughness of approx. 10 μm, without being in the unpleasant sense to look rough. The surface area 30 imparts a comfortable touch feel not unlike that of a slightly greasy paper surface. The slip-resistant effect of the surface region 30, which acts in the manner of a friction brake, remains largely present even in the case of wet and possibly soapy hands, so that a handle provided with such an insert remains intact during the operation Showers can be guided safely. The anti-slip effect is supported by small, flat grip recesses 31 which are distributed over the surface area 30 in a visually appealing distribution with approximately sixfold symmetry. The spherical segment-shaped recesses 31 with a depth of a few tenths of a millimeter and diameters of 1 to 2 mm can support the fluid displacement by the holding hand in the manner of tire profiles with a wet handle and in this way support the adhesion to the fingers in the region of the surface area 30. In contrast to also possible, outwardly projecting knobs or ribs cause the quasi punctiform depressions even with prolonged, firm holding the handle no unpleasant pressure points.

Durch die regelmäßige Verteilung der Vertiefungen ist gleichzeitig eine in Fig. 2 gut zu erkennende Musterung des griffgünstigen Bremsabschnittes 30 geschaffen, durch die die Optik des Handgriffes aufgelockert werden kann. Die Ästhetik der Handbrause kann weiterhin dadurch gefördert werden, daß der Oberflächenbezirk 30 eine sich von der umgebenden Oberfläche 11 unterscheidende Farbgebung hat, was dank der Einfärbbarkeit des verwendeten thermoplastischen Kautschuks ohne Aufwand möglich ist. So ist es insbesondere möglich, einer Handbrause einen Satz bzgl. ihrer Einbaumaße identischer Rutschsicherungselemente 15 zuzuordnen, die bei Bedarf zur optischen Anpassung an die Umgebung am Gehäuse der Handbrause mühelos befestigt werden können. Griffeinlagen der gezeigten oder einer ähnlichen Art können alternativ oder zusätzlich auch an dem der Unterseite 13 gegenüberliegenden Griffrücken oder an einer oder beiden Seiten des Handgriffes angebracht sein. Auch diese Einlagen können leicht oder auch stärker profiliert sein.Due to the regular distribution of the wells is at the same time a in Fig. 2 good to be recognized pattern of the handy brake section 30 created by the optics of the handle can be loosened. The aesthetics of the hand shower can be further promoted by the fact that the surface area 30 has a different color from the surrounding surface 11, which is possible without any effort thanks to the colorability of the thermoplastic rubber used. Thus, it is in particular possible to assign a set with respect to their mounting dimensions identical slip protection elements 15 a hand shower, which can be easily attached as needed for optical adjustment to the environment on the housing of the hand shower. Handle inserts of the type shown or of a similar type may alternatively or additionally also be attached to the handle back opposite the underside 13 or to one or both sides of the handle. These deposits can be slightly or more profiled.

Die Handbrause 1 hat zusätzlich zu dem durch die haptische Griffeinlage 15 gebildeten Oberflächenbezirk 30 an weiteren Stellen rutschfeste Griffoberflächen. Der gegenüber dem Brausekopf verdrehbare, mit der Strahlscheibe 9 gekoppelte und zu deren Verdrehung gegenüber einem Kern des Brausekopfes vorgesehene Betätigungshebel 10 hat einen radial zur Brausekopföffnung in genereller Richtung des Handgriffs 2 vorspringenden Hebelkern 35 mit einer nach unten vorspringenden Nase 36. Auf den Hebelkern 35 ist ein zuckerhutförmiger Aufsatz 37 aufgesteckt, an dessen äußerer Oberfläche 38 ein Benutzer zur Verstellung des Strahlbildes beispielsweise mit dem Daumen angreift. Auch bei dem stark konvex gekrümmten Oberflächenbezirk 38 kommt es zur sicheren Handhabung der Brause darauf an, daß ein Benutzer bei der Strahlverstellung nicht abrutscht. Der Aufsatz 37 ist, genau wie der Einsatz 15, als einstückiges, vorgeformtes Spritzgußteil aus thermoplastischem Kautschuk ausgebildet und hat in seinem Inneren eine der äußeren Form des Hebelkerns 35 angepaßte Aufnahmeöffnung, die von der flachen, dem Brausekopf zugewandten Seite des Aufsatzes durch eine Öffnung zugänglich ist. Zur Befestigung des hütchenförmigen Aufsatzes wird dieser unter Anwendung von Druck auf den Hebelkern 35 aufgeschoben und verrastet im vollends aufgeschobenen Zustand im Bereich der Nase 36 mit dem Hebelkern. Aufgrund der Gummielastizität des Aufsatzmateriales ist das Aufschieben unter Verformung des Aufsatzes ohne Zerstörung desselben möglich. Genauso kann ein derartiger Aufsatz, falls gewünscht, ohne Zuhilfenahme von Werkzeugen wieder vom Hebelkern 35 abgezogen und durch einen andersartigen, beispielsweise andersfarbigen und/oder anders oberflächlich profilierten Aufsatz ersetzt werden.The hand shower 1 has in addition to the surface area 30 formed by the haptic handle insert 15 in other places non-slip grip surfaces. The relative to the shower head rotatable, coupled to the jet disk 9 and provided for rotation with respect to a core of the shower head actuating lever 10 has a radially to the shower head opening in the general direction of the handle 2 projecting lever core 35 with a downwardly projecting nose 36. On the lever core 35 is a sugar-cap-shaped attachment 37 attached, on the outer surface 38, a user attacks to adjust the spray pattern, for example, with the thumb. Even with the highly convex curved surface area 38, it comes to safe handling of the shower on it that a user does not slip off during beam adjustment. The cap 37 is, as well as the insert 15, formed as a one-piece, preformed injection molded thermoplastic rubber and has in its interior a the outer shape of the lever core 35 adapted receiving opening, accessible from the flat, the shower head side facing the essay through an opening is. To attach the hat-shaped attachment this is pushed by applying pressure to the lever core 35 and locked in the fully pushed state in the nose 36 with the lever core. Due to the rubber elasticity of the attachment material pushing it under deformation of the essay without destroying it is possible. Similarly, such an essay, if desired, without the aid of tools withdrawn from the lever core 35 and replaced by a different, for example, differently colored and / or otherwise superficially profiled essay.

Die Erfindung schlägt also insbesondere eine Handbrause vor, die in Teilbereichen der Oberfläche mindestens des Handgriffs rutschfeste, griffsichere, flächig ausgedehnte Oberflächenbezirke hat. Diese können insbesondere durch Einsätze oder Aufsätze aus Materialien mit gummiartigen Oberflächen bestehen, wobei die Oberflächen ggf. auch strukturiert bzw. profiliert sein können. Derartige Oberflächenbezirke können bzgl. ihrer Form, Farbgebung und/oder Musterung so gestaltet sein, daß sie die Optik der Handbrause auflockern und aufwerten und insbesondere für bessere Griffeigenschaften sorgen. Handbrausen, deren Haptik erfindungsgemäß verbessert ist, ermöglichen eine sichere Führung auch mit nassen oder seifigen Händen.The invention thus proposes, in particular, a hand shower which, in partial regions of the surface of at least the handle, has non-slip, grip-proof, extensively extended surface areas Has. These can in particular consist of inserts or attachments made of materials with rubber-like surfaces, wherein the surfaces may possibly also be structured or profiled. With regard to their shape, coloring and / or patterning, such surface areas may be designed in such a way that they loosen up and enhance the appearance of the hand shower and, in particular, provide better grip properties. Hand showers, the feel of which is improved according to the invention, enable safe guidance even with wet or soapy hands.
