Abstract
WC-Bürsten mit Wechselkopf sehen komplexe Mechaniken vor, welche ein Austauschen des Kopfes ermöglichen. Diese sind nachteilig störanfällig oder zu komplex und finden im Markt wenig Akzeptanz. Aufgabe ist, diese Nachteile zu überwinden. Die Lösung erfolgt durch eine dreiteilige WC-Bürste mit Wechselkopf, bei der eine Hülse über jeweils einen Anschlag zwischen Wechselkopf und Stiel gefasst ist und der Stiel über eine durch die Hülse hindurchragende Seele lösbar mit dem Wechselkopf verbunden ist. Hier muss ein Nutzer lediglich die Hülse mit einer Hand fassen und den Stiel verschieben oder verdrehen, um eine Entkoppelung von Wechselkopf und Stiel zu bewirken. Diese überraschend einfache Funktionsweise kann von einem Nutzer direkt angewendet werden und ist extrem robust und langlebig, was Resourcen schont und somit erhebliche Vorteile für Kunden und Umwelt bietet.Toilet brushes with replaceable head provide complex mechanics, which allow a replacement of the head. These are disadvantageously susceptible to interference or too complex and find little acceptance in the market. The task is to overcome these disadvantages. The solution is carried out by a three-piece toilet brush with replaceable head, in which a sleeve is taken over a respective stop between the replaceable head and stem and the stem is connected via a protruding through the sleeve soul releasably connected to the removable head.

This surprisingly simple functionality can be directly applied by a user and is extremely robust and durable, which saves resources and thus provides significant benefits for customers and the environment.
Description
Die vorliegende Erfindung betrifft WC-Bürsten mit Wechselkopf gemäß dem Oberbegriff der unabhängigen Ansprüche. Der technische Bereich umfasst somit Verbesserungen von Nutzgegenständen im Bad- und Sanitärbereich.The present invention relates to toilet brushes with replaceable head according to the preamble of the independent claims. The technical area thus includes improvements of utility objects in the bathroom and sanitary sector.
Gattungsgemäße WC-Bürsten mit Wechselkopf erlauben das vorteilhafte Austauschen des Kopfes der WC-Bürste. Der Kopf der Bürste wird mit der Zeit unansehnlich und die Borsten vergilben und es sammeln sich hartnäckige Anhaftungen auf diesen. Ein Wechselkopf kann hier von dem Stiel getrennt werden, um einen neuen Wechselkopf am Stiel zu befestigen. Der Stiel der Bürste bleibt so erhalten und kann material- und resourcensparend länger verwendet werden. Zu diesem Zweck ist ein als Wechselkopf ausgebildeter Bürstenkopf lösbar mit dem Stiel verbunden und die Verbindung erlaubt beispielsweise über Steck- oder Rast-Koppelungen das Anbringen eines neuen Wechselkopfes. Hierbei wird regelmäßig angestrebt, den Wechselkopf berührungsfrei - also ohne Berühren des Kopfes an sich - austauschen zu können.Generic toilet brushes with replaceable head allow the advantageous replacement of the head of the toilet brush. Over time, the head of the brush becomes unsightly and the bristles turn yellow and stubborn buildup accumulates on it. A replaceable head can here be separated from the stem to attach a new replaceable head on a stick. The handle of the brush is retained and can be used longer in terms of material and resources. For this purpose, designed as a replaceable head brush head is detachably connected to the stem and the compound allows, for example via plug or locking couplings attaching a new replaceable head. In this case, it is regularly desired to be able to exchange the replaceable head without contact - ie without touching the head itself.
Der Stand der Technik kennt vielfältige Verbesserungen dieser Funktion. Die
Nachteilig ist bei den gattungsgemäßen Ausführungsformen, dass die für den Wechsel des Bürstenkopfes entwickelten Mechaniken alle sehr komplex und auch anfällig sind. Es dauert mindestens Monate, bis ein Bürstenkopf durch normale Benutzung unansehnlich geworden ist. Eine hoch komplexe Mechanik müsste dann nutzerseitig immer wieder neu erlernt, erprobt und benutzt werden. Aber auch die einfacheren Mechaniken sehen stets Hebel, Seilzüge und gleichsinnige, gesonderte Kraftdurchleitungen vor, die gerade bei KunststoffKomponenten bruch- und störanfällig sind. Auf diese Nachteile führen die Erfinder zurück, dass sich im Markt nur die ganz einfachen Steck-Köpfe haben gut durchsetzen können. Es besteht mithin ein Bedarf nach einer robusten Konstruktion, welche ein berührungsfreies Wechseln erlaubt und dabei in der Bedienung so einfach gehalten ist, dass der Markt dies als sofort in bekannter Weise bedienbare Variante des etablierten Designs akzeptieren kann.A disadvantage of the generic embodiments that the mechanisms developed for the change of the brush head are all very complex and prone. It takes at least months for a brush head to become unsightly during normal use is. A highly complex mechanics would have to be re-learned, tested and used again and again by the user. But even the simpler mechanisms always provide levers, cables and the same direction, separate power transmission, which are fragile and prone to failure especially with plastic components. The inventors attribute these disadvantages to the fact that only the very simple plug-in heads have been able to gain acceptance in the market. Thus, there is a need for a robust construction that allows non-contact switching while being so simple to operate that the market can accept this as an immediately operable variant of the established design.
Aufgabe der vorliegenden Erfindung war es daher, die Nachteile des Standes der Technik zu überwinden und eine WC-Bürste mit Wechselkopf bereitzustellen, welche eine dahingehend verbesserte Wechselfunktion bereitzustellen vermag.Object of the present invention was therefore to overcome the disadvantages of the prior art and to provide a toilet brush with replaceable head, which is able to provide an improved switching function to the effect.
Die Lösung dieser Aufgabe erfolgt gemäß der Merkmale der unabhängigen Ansprüche. Vorteilhafte Ausführungsformen ergeben sich aus den abhängigen Ansprüchen sowie der nachfolgenden Beschreibung.The solution of this object is achieved according to the features of the independent claims. Advantageous embodiments will become apparent from the dependent claims and the following description.
Erfindungsgemäß ist eine WC-Bürste mit Wechselkopf, wobei der unterseitige Wechselkopf mit einem oberseitigen Stiel berührungsfrei austauschbar verbunden ist, dadurch gekennzeichnet, dass die WC-Bürste eine auf den Stiel außenseitig aufgeschobene Hülse in Hohlzylinderform aufweist, wobei die Hülse an beiden Enden über jeweils mindestens einen Anschlag zwischen Wechselkopf und Stiel gefasst ist und der Stiel über eine durch die Hülse hindurchragende Seele lösbar mit dem Wechselkopf verbunden ist.According to the invention, a toilet brush with replaceable head, wherein the underside replaceable head is connected to an upper-side handle contactless interchangeable, characterized in that the toilet brush has an externally slid on the stem sleeve in hollow cylindrical shape, wherein the sleeve at both ends via at least a stop between the replaceable head and handle is taken and the stem is connected via a protruding through the sleeve soul releasably connected to the removable head.
Erfindungsgemäß weist eine WC-Bürste mit Wechselkopf, bei der der unterseitige Wechselkopf mit einem oberseitigen Stiel berührungsfrei austauschbar verbunden ist, eine auf den Stiel außenseitig aufgeschobene Hülse in Hohlzylinderform auf. Somit ist die WC-Bürste oberhalb des Kopfes von außen betrachtet zweiteilig aufgebaut und kann am oberseitigen, endständigen Griff des Stiels gefasst werden, während im darunter liegenden Bereich sich die Hülse anschließt. Im Sinne der vorliegenden Erfindung wird die Bürste hierbei in typischer Benutzungslage betrachtet, wodurch der Wechselkopf 'unten' und mithin am 'Ende' angeordnet ist, während der Griff 'oben' und am Anfang der WC-Bürste angeordnet ist. So betrachtet weist eine typische WC-Bürste eine von oben nach unten verlaufende Längserstreckung auf, welche gleichsinnig zur Erstreckungsrichtung des Stiels ausgerichtet ist. Die Hülse ist zwischen dem Griff des Stiels und dem Wechselkopf angeordnet und an beiden Enden über jeweils mindestens einen Anschlag zwischen Wechselkopf und Stiel gefasst. 'Anschlag' bezeichnet hierbei eine kraftschlüssig anliegende, quer zur Erstreckungsrichtung ausgerichtete und bevorzugt durchgehende Ringfläche, auf welcher die Hülse an ihren Enden aufliegt. Stiel und Wechselkopf sind mithin unter Klemmspannung miteinander verbunden und fassen die Hülse jeweils über einen Anschlag, welcher sich im Längsschnitt betrachtet mit im wesentlichen L-förmigem Profil an die Hülse anschmiegt. Bevorzugt ist der Anschlag nach Außen hin im Übergangsbereich von Stiel zu Hülse und von Hülse zu Wechselkopf hin mit einem kontinuierlichen Außendurchmesser gefertigt, sodass die WC-Bürste im zusammengesetzten Zustand eine kontinuierliche, durchgehende Außenfläche aufweist. Besonders bevorzugt weisen Stiel und Hülse hierbei einen von oben nach unten konisch verjüngenden Außendurchmesser auf, wodurch Material gespart werden kann, aber trotzdem bei harmonischer Außenkontur ein Griff üblicher Dicke möglich bleibt. Der Stiel ist über eine durch die Hülse hindurchragende Seele lösbar mit dem Wechselkopf verbunden. Durch diese Bauweise kann die außenseitig angeordnete Hülse sowohl als Dekorationselement als auch als funktionales Element für eine Wechselfunktion verwendet werden: Werden StielGriff und Hülse von einem Nutzer gefasst und gegeneinander bewegt, so wirkt die aufgebrachte Kraft direkt auf die Verbindung von Stiel und Wechselkopf ein: Der Wechselkopf kann, ohne ihn zu berühren, von dem Stiel gelöst werden. Zusätzliche, komplexe Mechaniken, welche nachteilig versagen könnten, sind dabei komplett vermieden. Die Bedienung ist denkbar einfach und kann sofort umgesetzt werden. Schon die Information, dass der Wechselkopf hier berührungsfrei austauschbar ist, ist ausreichend, um einen Nutzer in die Lage zu versetzen, den Wechsel vorzunehmen.According to the invention, a toilet brush with a replaceable head, in which the underside replaceable head is connected interchangeably without contact with an upper-side stalk, has a sleeve, which is pushed onto the stalk on the outside, in a hollow-cylindrical form. Thus, the toilet brush above the head viewed from the outside is constructed in two parts and can be taken at the top, the terminal handle of the stem, while in the underlying area, the sleeve connects. For the purposes of the present invention, the brush is considered here in typical use situation, whereby the replaceable head 'down' and therefore at the 'end' is arranged, while the handle is 'up' and arranged at the beginning of the toilet brush. Viewed in this way, a typical toilet brush has a longitudinal extension running from top to bottom on, which is aligned in the same direction to the extension direction of the stem. The sleeve is arranged between the handle of the handle and the replaceable head and taken at both ends via at least one stop between the replaceable head and handle. 'Stop' here refers to a frictionally fitting, aligned transversely to the direction of extension and preferably continuous annular surface on which the sleeve rests at their ends. Stem and replaceable head are therefore connected to each other under clamping voltage and hold the sleeve each have a stop which, as viewed in longitudinal section, conforms to the sleeve with a substantially L-shaped profile. Preferably, the stop is made to the outside in the transition region from stem to sleeve and sleeve to replaceable head out with a continuous outer diameter, so that the toilet brush has a continuous, continuous outer surface in the assembled state. Stem and sleeve in this case particularly preferably have an outer diameter which conically tapers from top to bottom, as a result of which material can be saved, but nevertheless a handle of customary thickness remains possible with a harmonious outer contour. The stem is releasably connected to the replaceable head via a core projecting through the sleeve. By this construction, the sleeve arranged on the outside can be used both as a decorative element and as a functional element for a change function: If handle and sleeve taken by a user and moved against each other, the applied force acts directly on the connection of stem and replaceable head: The replaceable head can be detached from the handle without touching it. Additional, complex mechanisms, which could disadvantageously fail, are completely avoided. The operation is very simple and can be implemented immediately. Even the information that the replaceable head is replaceable without contact here is sufficient to enable a user to make the change.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass die Hülse aus rostfreiem Edelstahl besteht. Dieses Material erlaubt eine erhöhte, robuste Stabilität bei geringem Gewicht.Preferably, the toilet brush is characterized in that the sleeve is made of stainless steel. This material allows increased, robust stability with low weight.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass die Hülse am oberen und/oder unteren Ende ein ringförmiges Adapterstück aus Kunststoff aufweist. Ein Kunststoff-Adapterstück erlaubt es, die Härte und Rauigkeit der Reib- und Kontaktflächen der Anschläge gleichmäßiger zu halten, wodurch auch bei häufigem Wechsel des Wechselkopfes ein vorzeitiger Verschleiß vorteilhaft vermieden wird.Preferably, the toilet brush is characterized in that the sleeve has an annular adapter piece made of plastic at the upper and / or lower end. A plastic adapter piece makes it possible to keep the hardness and roughness of the friction and contact surfaces of the attacks uniform, whereby premature wear is advantageously avoided even with frequent change of the replaceable head.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass die WC-Bürste am unteren Ende der Hülse mindestens eine umgreifende, parallel zur Erstreckungsrichtung des Stiels angeordnete Steg-Nut-Koppelung mit dem Wechselkopf aufweist. Eine umgreifende Steg-Nut-Koppelung umfasst eine Nut einerseits und einen formschlüssig passenden Steg andererseits. Solche Koppelungen sind als Verdrehsicherungen aus dem Bereich von Anschluss-Steckern von elektrischen Geräten bekannt. Im vorliegenden Anwendungsfall können Hülse und Wechselkopf parallel zu einer Aufsteckrichtung einer Steckverbindung über diese Koppelung gegen ungewolltes Ausdrehen gesichert werden und eine eindeutige, räumliche Anordnung der beiden Baugruppen zueinander kann vorgegeben werden. Besonders vorteilhaft wird diese Verdrehsicherung mit einer parallelen, innenseitigen Verschraubung von Stiel und Wechselkopf kombiniert: Ein Verdrehen des Stiels bei fest gehaltener Hülse bewirkt dann lediglich eine Verschiebung von Hülse und Wechselkopf zueinander, wobei der Steg in der zugehörigen Nut ein- oder ausgeschoben wird.Preferably, the toilet brush is characterized in that the toilet brush has at least one encompassing, parallel to the extension direction of the stem arranged web-groove coupling with the replaceable head at the lower end of the sleeve. An encompassing web-groove coupling comprises a groove on the one hand and a form-fitting matching web on the other. Such couplings are known as anti-rotation devices in the field of connection plugs of electrical equipment. In the present application sleeve and exchangeable head can be secured parallel to a mounting direction of a connector over this coupling against unwanted unscrewing and a clear, spatial arrangement of the two modules to each other can be specified. Particularly advantageously, this anti-rotation device is combined with a parallel, inside screw connection of the handle and interchangeable head. A rotation of the handle when the sleeve is held firmly then merely causes a displacement of the sleeve and interchangeable head relative to one another, with the web being pushed in or out in the associated groove.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass Wechselkopf und Seele über eine Verschraubung lösbar miteinander verbunden sind. Eine Verschraubung erlaubt bei einer Gewindelänge, welche passend zur Elastizität der Hülse ausgelegt ist, bei zusammengesetzter und verschraubter Bürste eine elastische Klemmspannung vorzugeben, mit welcher die Hülse zwischen den beiden Anschlägen fixiert ist und den Stiel und den Wechselkopf im Reibschluss in der Verschraubung sichert.Preferably, the toilet brush is characterized in that the replaceable head and soul are releasably connected to each other via a screw. A screw allows for a thread length, which is designed to match the elasticity of the sleeve, with composite and screwed brush specify an elastic clamping voltage with which the sleeve is fixed between the two stops and secures the stem and the replaceable head in frictional engagement in the screw.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass unterseitiger Wechselkopf und Seele mit oberseitigem Stiel aus Kunststoff bestehen. Kunststoffe können in ihren materialtechnischen und optischen Eigenschaften besonders einfach angepasst werden. Ist ein Mal eine Hohlform zur Extrusion oder zum Blasformen der benötigten Teile gefertigt worden, kann durch Abmischen der Kunststoffmischung besonders vorteilhaft eine Farbkombination oder Materialpaarung bereitgestellt werden, welche dem jeweiligen Markt gerecht wird.Preferably, the toilet brush is characterized in that underside interchangeable head and soul with upper-side stem made of plastic. Plastics can be adapted particularly easily in terms of material and optical properties. Once a mold has been produced for extrusion or blow molding of the required parts, a color combination or combination of materials can be provided by blending the plastic mixture in a particularly advantageous manner which satisfies the respective market.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass der oberseitige Stiel in einem von der Hülse abgedeckten Bereich zumindest abschnittsweise aus elastischem Kunststoff besteht und einen Außendurchmesser aufweist, welcher den Innendurchmesser der Hülse im Umfang der elastischen Deformierbarkeit der lokalen Materialpaarung überschreitet. Durch diesen Kunstgriff wird die Hülse zusätzlich mit elastischer Klemmspannung auf dem Stiel fixiert und das Risiko eines ungewollten Lösens einer Verschraubung kann so besonders vorteilhaft minimiert werden.Preferably, the toilet brush is characterized in that the upper-side stem in an area covered by the sleeve at least partially made of elastic plastic and having an outer diameter which exceeds the inner diameter of the sleeve in the extent of elastic deformability of the local material pairing. By this trick the sleeve is additionally fixed with elastic clamping voltage on the stem and the risk of unwanted loosening a screw can be minimized so particularly advantageous.
Bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass der Stiel eine austauschbare Seele aufweist, wobei die Seele länger ist als die umgebende Hülse und die Seele im zusammengesetzten Zustand der WC-Bürste vollständig von der Hülse verdeckt ist. Diese Ausführungsform bietet zudem bei abgeschraubtem Wechselkopf den Vorteil, dass die Seele zumindest mit einer Koppelungseinrichtung, bevorzugt einem Außengewinde, gut sichtbar über die Hülse hinausragt. Ein neuer Wechselkopf kann dann - bevorzugt in einer zugehörigen WC-Bürstenhalterung - vorgelegt werden, um die überstehende Seele - bei händischer Ausrichtung der Seele über die Hülse - einzusetzen und ggf. einzudrehen, um den neuen Wechselkopf am Stiel zu fixieren.Preferably, the toilet brush is characterized in that the stem has a replaceable soul, wherein the soul is longer than the surrounding sleeve and the soul is completely covered by the sleeve in the assembled state of the toilet brush. This embodiment also offers the unscrewed replaceable head the advantage that the soul at least with a coupling device, preferably an external thread, protrudes well over the sleeve. A new replaceable head can then - be presented - preferably in an associated toilet brush holder - to use the supernatant soul - with manual alignment of the soul on the sleeve - and possibly screw in to fix the new replaceable head on the stem.
Besonders bevorzugt ist die WC-Bürste dadurch gekennzeichnet, dass die Seele unterseitig ein Außengewinde aufweist, welches im zusammengestzten Zustand der WC-Bürste in eine Fassung des Wechselkopfes mit Innengewinde eingreift und dabei am unterseitigen Ende über die Hülse hinausragt und hintergreifend in den Wechselkopf hineinragt. So kann ein neuer Wechselkopf - besonders bevorzugt in Kombination mit der vorbeschriebenen Steg-Nut-Koppelung - durch einfaches Verdrehen von Stiel und Hülse gegeneinander - montiert und auch demontiert werden.Particularly preferably, the toilet brush is characterized in that the soul has an external thread on the underside, which engages in the compressed state of the toilet brush in a version of the interchangeable head with internal thread and protrudes at the lower end over the sleeve and protruding into the interchangeable head. Thus, a new replaceable head - particularly preferably in combination with the above-described web-groove coupling - by simply turning the stem and sleeve against each other - mounted and disassembled.

In vorteilhafter Ausführungsform ist eine WC-Bürste mit Wechselkopf als dreiteilige Bürste ausgebildet, bei der ein unterseitiger Wechselkopf mit einem oberseitigen Stiel berührungsfrei austauschbar verbunden ist und die WC-Bürste eine auf den Stiel außenseitig aufgeschobene Hülse in Hohlzylinderform aufweist, wobei im Detail
- die Hülse an beiden Enden über jeweils mindestens einen Anschlag zwischen Stiel und Wechselkopf gefasst ist,
- der Stiel über eine durch die Hülse hindurchragende Seele lösbar mit dem Wechselkopf verbunden ist
- die Hülse aus rostfreiem Edelstahl besteht,
- die Hülse am unteren Ende ein ringförmiges Adapterstück aus Kunststoff aufweist,
- Hülse und Wechselkopf eine umgreifende, parallel zur Erstreckungsrichtung des Stiels angeordnete Steg-Nut-Koppelung aufweisen,
- Wechselkopf und Seele über eine innen liegende Verschraubung lösbar miteinander verbunden sind,
- unterseitiger Wechselkopf, Seele und oberseitiger Stiel aus Kunststoff bestehen,
- der oberseitige Stiel in einem von der Hülse abgedeckten Bereich zumindest abschnittsweise aus elastischem Kunststoff besteht und einen Außendurchmesser aufweist, welcher den Innendurchmesser der Hülse im Umfang der elastischen Deformierbarkeit der lokalen Materialpaarung überschreitet,
- der Stiel eine austauschbare Seele aufweist, wobei die Seele länger ist als die umgebende Hülse und die Seele im zusammengesetzten Zustand der WC-Bürste vollständig von der Hülse verdeckt ist,
- die Seele unterseitig ein Außengewinde aufweist, welches im zusammengestzten Zustand der WC-Bürste in eine Fassung des Wechselkopfes mit Innengewinde eingreift und dabei am unterseitigen Ende über die Hülse hinaus hintergreifend in den Wechselkopf hineinragt.
- the sleeve is held at both ends by at least one stop between the handle and the replaceable head,
- the stem is releasably connected to the replaceable head via a core protruding through the sleeve
- the sleeve is made of stainless steel,
- the sleeve has an annular adapter piece made of plastic at the lower end,
- Sleeve and exchangeable head have a encompassing, arranged parallel to the extension direction of the stem web-groove coupling,
- Interchangeable head and soul are detachably connected to each other via an internal screw connection,
- underside replaceable head, soul and topped plastic handle,
- the upper-side stem in an area covered by the sleeve at least partially consists of elastic plastic and has an outer diameter which exceeds the inner diameter of the sleeve in the extent of the elastic deformability of the local material pairing,
- the stem has an exchangeable core, wherein the soul is longer than the surrounding sleeve and the soul is completely obscured by the sleeve in the assembled state of the toilet brush,
- the soul has underside an external thread, which engages in the compressed state of the toilet brush in a version of the interchangeable head with internal thread and thereby protrudes beyond the sleeve beyond the sleeve in the interchangeable head at the bottom end.
WC-Bürsten mit Wechselkopf sehen komplexe Mechaniken vor, welche ein Austauschen des Kopfes ermöglichen. Diese sind nachteilig störanfällig oder zu komplex und finden im Markt wenig Akzeptanz. Aufgabe ist, diese Nachteile zu überwinden.Toilet brushes with replaceable head provide complex mechanics, which allow a replacement of the head. These are disadvantageously susceptible to interference or too complex and find little acceptance in the market. The task is to overcome these disadvantages.
Die Lösung erfolgt durch eine dreiteilige WC-Bürste mit Wechselkopf, bei der eine Hülse über jeweils einen Anschlag zwischen Wechselkopf und Stiel gefasst ist und der Stiel über eine durch die Hülse hindurchragende Seele lösbar mit dem Wechselkopf verbunden ist.The solution is carried out by a three-piece toilet brush with replaceable head, in which a sleeve is taken over a respective stop between the replaceable head and stem and the stem is connected via a protruding through the sleeve soul releasably connected to the removable head.
Hier muss ein Nutzer lediglich die Hülse mit einer Hand fassen und den Stiel verschieben oder verdrehen, um eine Entkoppelung von Wechselkopf und Stiel zu bewirken. Diese überraschend einfache Funktionsweise kann von einem Nutzer direkt angewendet werden und ist extrem robust und langlebig, was Resourcen schont und somit erhebliche Vorteile für Kunden und Umwelt bietet.Here, a user only has to grasp the sleeve with one hand and move or twist the handle in order to effect a decoupling of replaceable head and handle. This surprisingly simple functionality can be directly applied by a user and is extremely robust and durable, which saves resources and thus provides significant benefits for customers and the environment.
