Abstract

The invention relates to a toilet seat having an elongate housing (13) which can be fixed to the rear region of a toilet bowl, having an adjacent arrangement, provided in the housing, of a supply reel (28) for a tubular film, in particular made of plastic, a drive unit (36) and a winding reel (32), which can be connected to said drive unit, for the tubular film, having front outlet and inlet slots, constructed on the housing (13), for the tubular film, having a U-shaped lavatory seat (12) which ends outside the housing (13) in front of the slots and can be pivoted up relative to the housing (13) by means of a joint (16) located in front of the inlet slot and connected to the housing (13), and having a knife (40) arranged in front of the winding reel (32) for laterally cutting open the tubular film which is guided along and above the lavatory seat (12). For optimum utilisation of the housing, uncreased, space-saving winding of the used tubular film is achieved according to the invention in that the axis of rotation of the winding reel (32) runs perpendicular to the longitudinal direction of the seat end (18) attached in front of the inlet slot, in that there is arranged in the plane of the attached seat end (18) between the knife (40) and the winding reel (32) in the housing (13) an elongate - in particular slightly decelerated, roller-type - film deflection member (44) with a deflection running parallel to the axis of rotation of the winding reel (32), which film deflection member deflects the tubular film from the plane of the attached seat end (18) towards the winding reel (32), and in that a film flattener (42) is arranged in the plane of the attached seat end (18) between the knife (40) and the film deflection member (44), which film flattener pulls the tubular film during its longitudinal movement increasingly from the knife (40) towards the opposite side. The mutually flush axes of rotation of the supply reel (28) and the winding reel (32) preferably run in a space-saving manner in the longitudinal direction of the housing. All these measures allow an expedient enlargement of the seat depth of the toilet seat. <IMAGE>

Description

Die Erfindung betrifft einen Toilettensitz gemäß dem Oberbegriff von Anspruch 1.The invention relates to a toilet seat according to the preamble of claim 1.

Die DE-A-2835257 offenbart eine derartige Bauart gemäß Oberbegriff mit einer zusammen mit dem Gehäuse schwenkbaren Klosettbrille. Hierbei wird ein aus Kunststoff bestehender Folienschlauch eingesetzt. Es besteht das Problem eines sehr begrenzten Benutzungsvorrats bzw. einer häufigen Wartung, und zwar vor allem deshalb, weil beim Aufwickeln des seitlich geschlitzten Folienschlauches unter anderem wegen bei dieser Bauart unvermeidbaren Folienumlegungen der Rollendurchmesser der Aufwickelrolle deutlich größer als zuvor bei der Vorratsrolle wird. Demnach muß die Aufwickelrolle häufiger entfernt werden, als es unter Berücksichtigung der Vorratsrolle an sich efforderlich wäre. Das ist lästig und bereitet erhebliche Kosten, zumal auch der Schlauch durchgetrennt und aufwickelseitig erneut festgelegt werden muß. Um diesen Nachteil teilweise zu vermeiden, müßte ein deutlich größeres Gehäuse verwendet werden. Bei diesem Toilettensitz liegt ohnehin schon deshalb eine schlechte Gehäuseausnutzung vor, weil die Drehachsen der Vorrats- und Aufwickelrollen schräg zueinander verlaufen. Das wiederum verkleinert in sehr nachteiliger Weise die Sitztiefe.DE-A-2835257 discloses such a type according to the preamble with one with the housing swiveling toilet glasses. This is made of plastic existing film tube used. There is a very limited problem Use reserve or frequent maintenance, mainly because because when winding up the laterally slit film tube, among other things due to the unavoidable film transfers of the roll diameter the take-up roll becomes significantly larger than before with the supply roll. Accordingly the take-up reel can be removed more often than it is considering the supply reel would be required per se. This is annoying and involves considerable costs, especially also cut the hose and fix it again on the take-up side got to. To partially avoid this disadvantage, a much larger housing would have to be used be used. This toilet seat already has one anyway bad housing utilization because of the axes of rotation of the supply and take-up rolls run at an angle to each other. That in turn made it very disadvantageous Way the seat depth.

Die SE-A-87682 offenbart einen Toilettensitz mit festem Gehäuse sowie schwenkbarer Klosettbrille und mit einem Folienschlauch aus Papier. Das Papier ermöglicht wegen seiner Dicke und Steifigkeit einen nur relativ kleinen Benutzungsvorrat auf den Rollen und hat unter anderem wegen seiner Zerreißbarkeit, insbesondere im Feuchtzustand, weitere Nachteile bei der praktischen Handhabung.SE-A-87682 discloses a toilet seat with a fixed housing and swiveling Toilet glasses and with a film tube made of paper. The paper allows due to its thickness and rigidity, only a relatively small amount of use the roles and has among other things because of its tearability, especially in Moist condition, further disadvantages in practical handling.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen Toilettensitz der im Oberbegriff genannten Art mit einfachen Maßnahmen so auszubilden, daß sich bei vergleichsweise kleiner Gehäusegröße und damit großer Sitztiefe der gesamte Folienvorrat der Vorratsrolle auf die Aufwickelrolle aufwickeln läßt und daß somit zwischendurch diesbezügliche Wartungsmaßnahmen der geschilderten Art entfallen können.The present invention is therefore based on the object of a toilet seat of the type mentioned in the preamble with simple measures so that the whole with a comparatively small housing size and thus a large seat depth Film supply of the supply roll can be wound onto the take-up roll and that therefore in between related maintenance measures of the type described can be omitted.

Zur Lösung der gestellten Aufgabe zeichnet sich ein Toilettensitz der im Oberbegriff von Anspruch 1 genannten Art erfindungsgemäß durch die im Kennzeichen dieses Anspruchs aufgeführten Merkmale aus. Diese Maßnahmen stellen insbesondere in Verbindung miteinander ein optimal raumsparendes Aufwickeln des benutzten Folienschlauches sicher und ermöglichen dadurch eine Verkleinerung des Gehäuses bzw. eine Vergrößerung der durch das Gehäuse begrenzten Sitztiefe. Durch den Folienflachleger werden dabei in Verbindung mit dem Folienumlenkglied in der Ebene der Klosettbrille und der Relativlage der Aufwickelrolle Folienumlegungen sicher vermieden. Außerdem begünstigt der die Folie zur gegenüberliegenden Seite ziehende Folienflachleger das Schneiden des Folienschlauches. Dabei ist der Begriff Folienflachleger so zu verstehen, daß durch diesen die vorher unebene, wie gekräuselte oder überlappte, Schlauchfolie flach gelegt wird. Der sich beim Aufwickeln des Schlauchvorrats der Vorratsrolle ergebende Enddurchmesser der Aufwickelrolle entspricht praktisch dem Anfangsdurchmesser der Vorratsrolle. Das Fluchten der Drehachsen führt zu einer optimalen Ausnutzung des Gehäuseinnenraums und dadurch zu einer Verkleinerung des Gehäuses bzw. einer Vergrößerung der Sitztiefe bei gleich großem Schlauchvorrat.To solve the task, a toilet seat stands out in the preamble of claim 1 type according to the invention by the in the characterizing this Claim listed features. These measures represent in particular Connection with each other an optimal space-saving winding of the used film tube safe and thereby enable the housing to be downsized or an increase in the seat depth limited by the housing. By the Foil flat layers are used in conjunction with the foil deflector in the plane the toilet seat and the relative position of the winding roll avoided. In addition, the one pulling the film to the opposite side favors Flat lay the cutting of the film tube. Here is the term Foil flat layer to understand that through this the previously uneven, like curled or overlapped, tubular film is laid flat. The one when winding up the The hose diameter of the supply roll corresponds to the end diameter of the take-up roll practically the initial diameter of the supply roll. Alignment of the axes of rotation leads to optimal use of the interior of the housing and thereby to reduce the size of the housing or increase the seat depth same hose stock.

Die Ausgestaltung von Anspruch 2 führt zu einer weiteren Verbesserung der Raumausnutzung, weil das Folienumlenkglied nicht das Gehäuse vergrößert.The embodiment of claim 2 leads to a further improvement in the use of space, because the film deflector does not enlarge the housing.

Gemäß den bevorzugten Weiterbildungen der Ansprüche 3 bis 5 kann ein gezieltes, den Folienschlauch schonendes und für das Aufwickeln straffendes Umlenken aus der Brillenebene zur Aufwickelrolle erfolgen. According to the preferred developments of claims 3 to 5, a targeted, deflecting the film tube gently and tightening for winding the plane of the glasses to the take-up roll.

Die Ausbildung gemäß Anspruch 6 ermöglicht in sehr kompakter Weise zunächst ein äußerst wirksames Schneiden der gespannten Folie und dann ein völlig faltenfreies Flachlegen der seitlich aufgeschnittenen Folie.The training according to claim 6 enables in a very compact manner an extremely effective cutting of the stretched film and then a completely wrinkle-free Lay the film cut open on the side.

Durch die Merkmale der Ansprüche 7 bis 9 läßt sich das Flachlegen der Folie optimieren, weil auch das der normalen Brillendicke entsprechende Folienmaterial durch seitliches Ziehen berücksichtigt wird. Dieses wird auch durch die Merkmale von Anspruch 10 begünstigt, weil die endseitige Breite der Brille mit abnehmender Dicke derselben zunimmt und somit keine Falten entstehen können.The flatness of the film can be optimized by the features of claims 7 to 9, because the film material corresponding to the normal glasses thickness is taken into account by pulling to the side. This is also due to the characteristics favored by claim 10 because the end width of the glasses with decreasing Thickness increases and no wrinkles can occur.

Auch Anspruch 11 begünstigt die Faltenfreiheit infolge des geringen Längsabstandes. Durch die Lage des Messers im Gehäuse wird die Unfallgefahr vermindert.Claim 11 also promotes freedom from wrinkles due to the small longitudinal distance. The position of the knife in the housing reduces the risk of accidents.

Die praktischen Ausführungsformen der Ansprüche 12 und 13 erleichtern das Erneuern des Folienvorrats, weil das den Folienschlauch von oben führende Folienumlenkglied durch seine Schwenkbarkeit leicht und schnell, gegebenenfalls selbsttätig, aus dem Einführungspfad für die Schlauchfolie entfernbar ist.The practical embodiments of claims 12 and 13 facilitate renewal of the film stock, because it guides the film tube from above due to its swiveling easily and quickly, if necessary automatically, can be removed from the insertion path for the tubular film.

Während Anspruch 14 eine ständige einwandfreie Führung und somit Faltenfreiheit der Folie gewährleistet, kann die Ausbildung von Anspruch 15 auf die sich bewegende Folie zusätzlich zentrierend wirken. Es hat sich aber gezeigt, daß grundsätzlich eine einfache zylindrische Rolle als Folienumlenkglied durchaus genügt. While claim 14 a constant flawless management and thus wrinkle-free guaranteed the film, the training of claim 15 on the moving Center film in addition. But it has been shown that fundamentally a simple cylindrical role as a foil deflecting member is quite sufficient.

Die praktischen Maßnahmen der Ansprüche 16 und 17 können für den Betrieb vorteilhaft sein. Während die Elastizität des Folienflachlegers eine gewisse Anpassung und Vergleichmäßigung der auf die Folie wirkenden Spreizkräfte ermöglicht, optimiert die Höhenverstellbarkeit des Messers den Schneidevorgang - insbesondere kann hierdurch auch ein faltenbildendes Verdrehen des Folienschlauches sicher vermieden werden. Ein solches Verdrehen führt zu einer Vergrößerung des Bewegungswiderstandes und kann bei Überschreitung eines gewissen Drehwinkels ein Blockieren des Schlauchtransportes bewirken.The practical measures of claims 16 and 17 can be advantageous for operation be. While the elasticity of the film flat layer some adjustment and enables equalization of the spreading forces acting on the film, optimized the height adjustment of the knife the cutting process - in particular can thereby also ensure a fold-forming twisting of the film tube be avoided. Such twisting leads to an increase in the resistance to movement and can occur when a certain angle of rotation is exceeded Block hose transport.

Die Abstützung des freien Brillenendes gemäß den Ansprüchen 18 bis 21 sorgt für eine ausreichende Lageabstützung bei genügendem Spiel für das Hochschwenken der Klosettbrille. Dadurch werden ein unbeabsichtigtes oder gewollt beschädigendes Abbiegen des freien Brillenendes und ein seitliches Wegziehen des Folienschlauches weitgehend vermieden. Die Merkmale von Anspruchs 22 oder 36 führen zu einem ähnlichen Ergebnis.The support of the free end of the glasses according to claims 18 to 21 ensures Adequate positional support with sufficient play for swiveling up the toilet glasses. This will result in an accidental or deliberately damaging Bend the free end of the glasses and pull the film tube away from the side largely avoided. The features of claim 22 or 36 lead to one similar result.

Die bevorzugten Weiterbildungen der Ansprüche 23 und 24 erlauben ein einfaches Anheben des Gehäuses im erwünschten Maße und ein wirksames Reinigen des darunter befindlichen Bereichs. Gegenüber schwenkbaren Gehäusen ergibt sich hierdurch ein wesentlicher hygienischer Vorteil. Außerdem erlaubt die exzentrische, drehbare Ausbildung ein leichtes Anpassen an unterschiedliche Einbaubedingungen.The preferred developments of claims 23 and 24 allow a simple Raising the case to the desired extent and effectively cleaning the area below. Compared to swiveling housings a significant hygienic advantage. In addition, the eccentric, rotatable design an easy adaptation to different installation conditions.

Gemäß der Ausgestaltung von Anspruch 25 kann in sehr einfacher Weise der verbleibende Folienvorrat bestimmt werden. Außerdem läßt sich über das Folienumlenkglied auch die Größe des Folienvorschubs genau festlegen. According to the embodiment of claim 25, the remaining one can in a very simple manner Foil stock can be determined. In addition, the film deflecting member also precisely define the size of the film feed.

Durch das Merkmal von Anspruch 26 wird dem Benutzer das Gefühl des Brillenendes definiert vermittelt, so daß keine Neigung besteht, die Sitzposition zu weit nach hinten und gegen das Gehäuse stoßend zu verlagern.The feature of claim 26 gives the user the feeling of the glasses end defined mediated so that there is no inclination to the sitting position too far to be moved behind and against the housing.

Die Maßnahme von Anspruch 27 verhindert auf sehr einfache Weise ein durch Unterdruckwirkung hervorgerufenes und die Weiterbewegung hemmendes Ansaugen des Folienschlauches an der Brillenunterseite.The measure of claim 27 prevents in a very simple way by negative pressure induced suction and inhibiting further movement of the film tube on the underside of the glasses.

Gemäß Anspruch 28 ergibt sich eine wesentliche Verbesserung der hygienischen Verhältnisse durch die desinfizierenden Maßnahmen im Bereich der Aufwickelrolle.According to claim 28 there is a significant improvement in the hygienic Conditions due to the disinfectant measures in the area of the winding roll.

Die bevorzugte endseitige Ausbildung der Schlauchfolie gemäß den Ansprüchen 29 bis 32 erlaubt ein einfaches, schnelles und zuverlässiges Manipulieren des freien Schlauchendes beim Ersetzen des Folienvorrats. Durch bloßes Ziehen an dem Verlängerungsstück wird der Folienschlauch seitlich gespreizt vorbewegt. Auch kann bei entsprechender Ausbildung beim Abwickeln von der Vorratsrolle ein selbsttätiges Öffnen des freien Endes des Folienschlauches erfolgen, was das Aufziehen desselben auf die Klosettbrille erheblich vereinfacht und beschleunigt.The preferred end design of the tubular film according to claims 29 up to 32 allows simple, quick and reliable manipulation of the free End of hose when replacing the film supply. By simply pulling on the extension piece the film tube is moved forward and spread apart. Can too with appropriate training when unwinding from the supply roll an automatic Opening the free end of the film tube is done, which is pulling it up on the toilet seat considerably simplified and accelerated.

Durch die Maßnahmen der Ansprüche 33 bis 35 kann das freie Schlauchende sehr leicht und äußerst schnell an der Aufwickelhülse festgelegt werden, beispielsweise durch bloßes Hindurchstecken des zungenförmigen freien Endes des Verlängerungsstücks.Through the measures of claims 33 to 35, the free hose end can be very can be easily and extremely quickly attached to the winding tube, for example by simply inserting the tongue-shaped free end of the extension piece.

Ein Toilettensitz 10 weist eine etwa U-förmige Klosettbrille 12 auf, die an ihrem einen Ende über ein Klappgelenk 16 mit einem Brillenhalter 18 verbunden ist. Der letztere greift durch einen vorderseitigen Eintrittsschlitz 15 in das Innere eines Gehäuses 13 ein und ist dort mit diesem verbunden. An ihrem anderen freien Brillenende 20 wird die Klosettbrille12 von einer Brillenstütze 22 gehalten, die im Bereich eines vorderseitigen Austrittsschlitzes 14 von dem Gehäuse 13 vorsteht und das freie Brillenende 20 unten, seitlich außen und gegebenenfalls teilweise auch oben abstützt. Die Klosettbrille 12 ist um das Klappgelenk 16 nach oben schwenkbar. Das freie Brillenende 20 hat hierfür ein ausreichendes Spiel (es kann stattdessen auch mit einem nicht dargestellten Gelenk oder anderen Mitteln versehen sein, die eine solche Schwenkbarkeit zulassen oder begünstigen).A toilet seat 10 has an approximately U-shaped toilet seat 12, which at one End is connected via a hinged joint 16 to a glasses holder 18. The latter reaches into the interior of a housing 13 through a front entry slot 15 one and is connected to it there. At the other free end of the glasses 20 the toilet seat 12 is held by an eyeglass support 22 in the area of a front Exit slot 14 protrudes from the housing 13 and the free end of glasses 20 is supported at the bottom, on the side and sometimes also on the top. The toilet glasses 12 can be pivoted upwards about the folding joint 16. The free end of glasses 20 has a sufficient game for this (instead it can also be played with a not shown Hinge or other means provided such pivotability allow or favor).

Ein seitliches Betätigungselement 26 ermöglicht ein weiterbewegendes Starten eines Mechanismus in der Weise, daß ein die Klosettbrille 12 schützend umschließender Kunststoff-Folienschlauch 46 etwa um eine Brillenlänge weiterbewegt wird, so daß im Brillenbereich stets ein hygienisch einwandfreier, schützender Schlauchabschnitt vorliegt. Der Folienschlauch 46 wird dabei von einer Vorratsrolle 28 (aus Folienschlauch) auf einer im Gehäuse 13 um eine Drehachse 30 drehbar gelagerten Vorratshülse 29 abgewickelt, durch den Austrittsschlitz 14 aus dem Gehäuse 13 gezogen, längs der Klosettbrille 12 von dieser geführt, durch den Eintrittsschlitz in das Gehäuse 13 gezogen und auf eine im Gehäuse 13 befindliche Aufwickelrolle 32 (aus Folienschlauch) auf einer drehbar antreibbaren Aufwickelhülse 33 aufgewickelt. Diese ist über eine Antriebsachse 34 mit einem Getriebemotor 36 verbunden, der von einer Stromversorgung 38, wie Akkus, gespeist wird.A lateral actuating element 26 enables a further moving start Mechanism in such a way that a protective enclosing the toilet seat 12 Plastic film tube 46 is moved about a length of glasses, so that in There is always a hygienically perfect, protective tube section. The film tube 46 is thereby from a supply roll 28 (from film tube) on a storage sleeve 29 which is rotatably mounted in the housing 13 about an axis of rotation 30 unwound, pulled through the outlet slot 14 from the housing 13, along the Toilet glasses 12 guided by this, pulled through the entry slot into the housing 13 and on a take-up roll 32 (made of film tube) located in the housing 13 wound on a rotatably drivable winding sleeve 33. This is about one Drive shaft 34 connected to a geared motor 36 by a power supply 38, like batteries.

Der Brillenhalter 18 trägt im Gehäuse 13 an seiner inneren Seite ein Messer 40, das den Folienschlauch 46 bei dessen Weiterbewegung seitlich aufschlitzt. An seiner gegenüberliegenden äußeren Seite trägt der Halter 18 einen spreizenden Folienflachleger 42, der den Folienschlauch 46 bei dessen Weiterbewegung zunehmend von dem Messer 40 seitlich nach außen wegzieht. Dadurch wird der Folienschlauch stets geordnet flachgelegt gehalten, also faltenfrei, und außerdem leichter geschnitten. The glasses holder 18 carries in the housing 13 on its inner side a knife 40 which slit the film tube 46 laterally as it continues to move. On its opposite on the outer side, the holder 18 carries a spreading foil flat layer 42, which the film tube 46 progressively from the Knife 40 pulls away to the side. As a result, the film tube is always organized kept flat, i.e. wrinkle-free, and also cut more easily.

In Weiterbewegungsrichtung hinter dem Halter 18 mit dem Messer 40 und dem Folienflachleger 42 folgt ein Folienumlenkglied 44, das vorliegend als drehbar gelagerte, leicht gebremste Rolle ausgebildet ist, deren Länge größer als die Breite des flachgelegten Folienschlauches 46 ist. Diese Rolle lenkt den faltenfreien Folienschlauch aus der Ebene der Klosettbrille 12 zwecks raumsparender enger Aufwicklung auf der Aufwickelrolle 32 zu dieser nach oben.In the direction of movement behind the holder 18 with the knife 40 and the flat foil layer 42 is followed by a film deflecting member 44, which in the present case is rotatably mounted, slightly braked roll is formed, the length of which is greater than the width of the laid flat Foil tube 46 is. This roller deflects the wrinkle-free film tube the level of the toilet seat 12 for the purpose of space-saving tight winding on the Winding roller 32 to this up.

Das Gehäuse 13 hat einen nach oben schwenkbaren Klappdeckel 48, der durch ein seitliches Schloß 49 am Gehäuse 13 lösbar festgelegt ist. Am Klappdeckel befindet sich gemäß Fig.1 eine digitale Vorratsanzeige 24, die den auf der Vorratsrolle 28 befindlichen restlichen Schlauchvorrat als Anzahl der mit diesem Vorrat noch möglichen Sitzbenutzungen anzeigt.The housing 13 has a hinged lid 48 which can be swiveled through lateral lock 49 is releasably fixed to the housing 13. Located on the hinged lid 1 there is a digital supply display 24, which is located on the supply roll 28 remaining hose supply as the number of possible with this supply Indicates seat use.

Zu diesem Zweck ist eine Elektronik 39 (Fig. 4) vorgesehen, die mit dem rollenförmigen Folienumlenkglied 44 gekoppelt ist und dessen Umdrehungen (damit auch die jeweilige Transportlänge des Folienschlauches 46) zählt. Es kann dabei ein Rückwartszahlen von einem Voreinstellwert für den eingebrachten Folienvorrat erfolgen. Die Elektronik 39 kann auch für die Einhaltung des erforderlichen Weiterbewegungsmaßes des Folienschlauches 46 pro Sitzbenutzung sorgen.For this purpose, electronics 39 (FIG. 4) are provided, which are connected to the roller-shaped Foil deflecting member 44 is coupled and its revolutions (hence the respective transport length of the film tube 46) counts. There may be a backward pay from a preset value for the introduced film supply. The electronics 39 can also be used to maintain the required degree of movement of the film tube 46 per seat use.

Das Gehäuse 13 ist für unterseitige Reinigungszwecke mittels zweier unterseitiger Gehäusebefestigungen 50 von einer Klosettschüssel 52 begrenzt anhebbar. Zu diesem Zweck weist jede Gehäusebefestigung 50 eine auf der Klosettschüssel 52 aufliegende Auflageplatte 54 auf, die oberseitig einen nach oben und mit Bewegungsspiel durch einen Gehäuseabsatz 58 in das Innere des Gehäuses 13 ragenden Führungsbolzen 56 trägt. Am freien Ende desselben befindet sich ein lösbarer Sicherungssplint, der durch Anschlagen am Gehäuse 13 den Bewegungshub desselben begrenzt. An der Unterseite trägt die Auflageplatte 54 einen nach unten durch die Klosettschüssel 52 ragenden und zum Führungsbolzen 56 exzentrisch angeordneten Gewindebolzen 57 mit einer endseitigen Befestigungsmutter 60. Durch ein Drehen des Gewindebolzens 57 beim Zusammenbauen kann das gegenseitige Abstandsmaß der Führungsbolzen 56 an die Einbaubedingungen der jeweiligen Klosettschüssel 52 angepaßt werden. Dieser Aufbau ermöglicht ein äußerst schnelles sowie einfaches Anheben des Gehäuses für Reinigungszwecke und Demontieren sowie Montieren durch bloßes Lösen des Sicherungssplints.The housing 13 is for underside cleaning purposes by means of two undersides Housing fastenings 50 can be raised to a limited extent by a toilet bowl 52. To this For this purpose, each housing attachment 50 has one resting on the toilet bowl 52 Platen 54 on the top one and with play through a housing shoulder 58 into the interior of the housing 13 projecting guide pin 56 wears. At the free end of the same is a releasable split pin, which limits the movement stroke of the same by striking the housing 13. On the underside, the support plate 54 carries one down through the toilet bowl 52 projecting and arranged eccentrically to the guide pin 56 Threaded bolt 57 with an end fastening nut 60. By turning of the threaded bolt 57 when assembling the mutual distance dimension the guide pin 56 to the installation conditions of the respective toilet bowl 52 be adjusted. This structure makes it extremely quick and easy Lift the housing for cleaning purposes and disassemble and assemble by simply loosening the safety pin.

Querwände 62 im Inneren des Gehäuses 13 dienen unter anderem zum drehbaren Lagern der verschiedenen Rollen und zum Unterteilen des Gehäuseinnenraums. Ein mittlerer Gehäuseabschnitt für die elektrischen und elektronischen Teile 36, 38, 39 ist zusätzlich von einem schützenden Zwischendeckel 64 abgedeckt.Cross walls 62 inside the housing 13 serve, among other things, for rotating Storage of the various roles and to divide the interior of the housing. A middle housing section for the electrical and electronic parts 36, 38, 39 additionally covered by a protective intermediate cover 64.

Die Aufwickelhülse 33 weist gemäß Fig. 5 an einer Stirnseite eine als Drehlagerung dienende Stummelwelle 66 oder dergleichen und an ihrer anderen Stirnseite mindestens einen Mitnehmerschlitz 68 auf, der für eine feste Drehverbindung mit dem Getriebemotor 36 sorgt.According to FIG. 5, the winding sleeve 33 has a rotary bearing on one end face serving stub shaft 66 or the like and at least on its other end face a drive slot 68, which is for a fixed rotary connection to the geared motor 36 cares.

Am freien vorderen Ende des Folienschlauches 46 befindet sich gemäß den Fig. 5 und 6 ein stabiles, flexibles Griff- bzw. Verlängerungsstück 72. Dieses hat ein etwa über die Breite des flachgelegten Folienschlauches 46 verlaufendes und diesen spreizendes hinteres Befestigungsende 74, das einfach auf die Außenseite des Schlauches aufgeklebt sein kann. Das Verlängerungsstück 72 ist so am Schlauch festgelegt, daß es sich beim Abziehen des Folienschlauches 46 von der Vorratsrolle 28 und beim Aufziehen desselben auf die Klosettbrille 12 stets oben befindet. Dadurch sind eine gute Zugänglichkeit und eine leichte Handhabung gewährleistet.According to FIG. 5, there is at the free front end of the film tube 46 and 6 a stable, flexible handle or extension piece 72. This has an approximately extending over the width of the flat film tube 46 and this spreading rear attachment end 74 which is simply on the outside of the hose can be glued on. The extension piece 72 is fixed to the hose in such a way that it is when pulling the film tube 46 from the supply roll 28 and Pulling the same on the toilet seat 12 is always on top. This makes one good accessibility and easy handling guaranteed.

Das vordere freie Ende des Verlängerungsstücks 72 ist schmaler und als Streifen bzw. Zunge 76 ausgebildet, der bzw. die leicht mit zwei Fingern erfaßt werden kann, um den Folienschlauch 46 von der Vorratsrolle 28 abzuwickeln, durch den bei geöffnetem Klappdeckel 48 oben offenen Austrittsschlitz 14 herauszuziehen, auf die Klosettbrille 12 aufzuziehen, durch den bei geöffnetem Klappdeckel 48 oben offenen Eintrittsschlitz 15 wieder in das Gehäuse 13 zu ziehen und mit der Aufwickelhülse 33 zu verbinden. Da das Befestigungsende 74 die dünne, flexible Schlauchfolie seitlich nach außen spreizt, wird diese beim Manipulieren stets geordnet flachgelegt gehalten.The front free end of the extension piece 72 is narrower and as a strip or tongue 76, which can easily be gripped with two fingers, to unwind the film tube 46 from the supply roll 28, through the when open Pull out the hinged lid 48 on the top of the outlet slot 14, onto the toilet seat 12 open through the open at the top with the hinged cover 48 open Pull the entry slot 15 back into the housing 13 and with the winding sleeve 33 connect to. Since the attachment end 74 the thin, flexible tubular film laterally spreads outwards, it is always kept laid flat during manipulation.

Gemäß Fig. 6 weist das Verlängerungsstück 72 im Bereich des Befestigungsendes 74 im vorliegenden Fall zwei überstehende Seitenränder 78 auf, die mit einer gewissen Rückstellwirkung nach unten abgewinkelt und an der Unterseite des Folienschlauches 46 angeklebt sind. Diese Seitenränder 78 sorgen durch ihre Rückstellwirkung dafür, daß das von der Vorratsrolle 28 abgezogene freie Ende des Folienschlauches stets etwas geöffnet bleibt. Dadurch ist ein sehr leichtes Aufziehen auf die Klosettbrille 12 möglich. Es entfallen sämtliche zeitraubenden und lästigen Manipulationen zum Flachlegen und zum gleichzeitig geringfügigen Öffnen des Schlauchendes. Andererseits behindern die unter Druck ganz umlegbaren Seitenränder 78 nicht ein enges, raumsparendes Aufwickeln des Folienschlauches 46. Stattdessen kann auch nur ein Seitenrand 78 umgelegt bzw. abgewinkelt und unterseitig schlauchöffnend festgelegt sein. Die Seitenränder 78 können ferner durch andere, in etwa gleichwirkende Mittel ersetzt werden, wie durch eingearbeitete oder befestigte separate, schlauchöffnende Teile, die auch einseitig vorgesehen sein können.6, the extension piece 72 has in the area of the fastening end 74 in the present case two projecting side edges 78, which with a certain Restoring action angled downwards and on the underside of the film tube 46 are glued. These side edges 78 ensure through their restoring action to ensure that the free end of the film tube drawn off from the supply roll 28 something always stays open. This makes it very easy to put on the toilet seat 12 possible. All time-consuming and annoying manipulations are eliminated for laying flat and at the same time slightly opening the hose end. On the other hand, the side edges 78 which can be folded over completely under pressure do not impede one another tight, space-saving winding of the film tube 46. Instead, also only one side edge 78 folded or angled and tube opening on the underside be fixed. The side edges 78 can also by other, approximately the same effect Funds are replaced, such as by incorporated or fixed separate, hose opening parts, which can also be provided on one side.

Die zumindest oberseitige Versteifung des vorderen Schlauchendes führt auch dazu, daß sich der Folienschlauch beim Ziehen über die Klosettbrille nicht auf dieser verdrehen kann.The at least top stiffening of the front hose end also leads to that the film tube does not twist when pulling over the toilet seat can.

Gemäß Fig. 5 weist die Aufwickelhülse 33 mehrere in ihrer Längsrichtung verlaufende und über ihren Umfang verteilte Hülsenschlitze 70 auf. Diese sind im vorliegenden Fall radial angeordnet und durchdringen die Aufwickelhülse 33. Dadurch kann die Zunge 76 des Verlängerungsstücks 72 sehr schnell, in jeder Betriebslage und einfach durch die Aufwickelhülse 33 gesteckt und somit drehfest mit dieser verbunden werden. Es wird eine sichere faltenfreie Antriebsverbindung mit der Aufwickelhülse 33 hergestellt, ohne daß hierzu der Folienschlauch 46 zuvor mehrfach um die Aufwickelhülse geschlungen werden muß.5, the winding tube 33 has a plurality of ones running in its longitudinal direction and sleeve slots 70 distributed over its circumference. These are in the present Radially arranged case and penetrate the winding sleeve 33. This allows the Tongue 76 of the extension piece 72 very quickly, in any operating position and easily inserted through the winding sleeve 33 and thus connected to it in a rotationally fixed manner. There is a secure wrinkle-free drive connection with the winding sleeve 33 produced without this the film tube 46 previously several times around the winding tube must be looped.

Die Zunge 76 des Verlängerungsstücks 72 sollte möglichst so lang ausgebildet sein, daß sie an der Aufwickelhülse 33 festgelegt werden kann, bevor das Schlauchende das Messer 40 erreicht hat. Dadurch läßt sich das seitliche Schlitzen des Folienschlauches 46 allein durch motorisches Drehen der Aufwickelhülse 33 einleiten, was leichter und gleichmäßiger durchführbar ist. Auch ist es dann nicht erforderlich, die Unterseite des Schlauchendes an der Aufwickelseite manuell aus dem Bereich unter dem Halter 18 und den weiteren Teilen hochzuziehen. The tongue 76 of the extension piece 72 should be as long as possible that it can be fixed to the winding tube 33 before the hose end the knife has reached 40. This allows the film tube to be slit laterally 46 initiate what by turning the winding sleeve 33 alone is easier and more feasible. Nor is it then necessary to use the Manually underside the end of the hose on the winding side from the area below to pull up the holder 18 and the other parts.

Gemäß Fig. 3 kann aus einem Desinfektionsmittelbehälter 80 ein flüssiges Desinfektionsmittel über Bürsten 82 auf das Folienumlenkglied 44 und über dieses auf die aufzuwickelnde, benutzte Schlauchfolie 46 aufgetragen werden.3, a liquid disinfectant can be removed from a disinfectant container 80 via brushes 82 onto the film deflecting member 44 and over this onto the used tubular film 46 are applied.

Unter dem Begriff des Flachlegens wird in der Schlauchfolientechnik normalerweise das faltenfreie direkte Aufeinanderlegen der gespreizten Wandungen eines Folienschlauches verstanden. Der Begriff ist im vorliegenden Text jedoch allgemeiner zu verstehen und bezieht sich auch auf ein faltenfreies Spreizen der lediglich gegenseitig angenäherten Schlauchwandungen, also auf den Fall des teilweise geöffneten Folienschlauches.The term flat lay is usually used in tubular film technology the wrinkle-free direct stacking of the spread walls of a film tube Understood. However, the term is more general in this text understand and also refers to a wrinkle-free spreading of just each other approximate hose walls, so in the case of the partially open Film tube.

Die erfindungsgemäßen Maßnahmen erlauben ein sehr leichtes, schnelles und zuverlässiges Manipulieren sowie faltenfreies Aufwickeln der sehr dünnen und flexiblen Kunststoff-Schlauchfolie beim Auswechseln bzw. Erneuern des Folienvorrates. Dieses kann dadurch auch von völlig ungeübtem Personal zuverlässig durchgeführt werden. Da der Gehäuseinnenraum unter anderem durch das faltenfreie Aufwickeln der Schlauchfolie optimal ausgenutzt ist, kann ein vergleichsweise kleines Gehäuse benutzt werden, woduch sich die Sitztiefe entsprechend vergrößert. Es läßt sich nach der vorliegenden Erfindung ohne weiteres ein Toilettensitz realisieren, der einen großen Schlauchvorrat für etwa dreihundert Sitzbenutzungen aufnehmen kann und dennoch eine Vergrößerung der Sitztiefe durch Verkleinerung des Gehäuses um bis zu 5 cm gegenüber herkömmlichen Gestaltungen ermöglicht.The measures according to the invention allow a very easy, fast and reliable Manipulation and wrinkle-free winding of the very thin and flexible Plastic tubular film when changing or renewing the film supply. This can be performed reliably even by completely inexperienced personnel. Since the interior of the housing is partly due to the crease-free winding of the Tubular film is optimally used, a relatively small housing can be used be, which increases the seat depth accordingly. It subsides the present invention easily realize a toilet seat that one large hose stock for about three hundred seat uses and nevertheless an increase in the seat depth by reducing the housing by up to to 5 cm compared to conventional designs.
