In Fig. 1 ist vereinfacht ein Apparateghäuse mit 1 bezeichnet, welches mit seiner Rückseite R, beipielsweise an einer Wand einer öffentlichen Toilette, neben den Lavabos montiert ist.In FIG. 1, an apparatus housing is designated 1 in simplified form, which with its back R, for example on a Wall of a public toilet, mounted next to the washbasins is.

Angedeutet ist ein aufklappbarer Deckel la, dessen über Scharniere 1b geöffnete Position, mit 1a' bezeichnet und dargestellt ist.A hinged lid la is indicated, its over Hinges 1b open position, labeled 1a 'and is shown.

Eine notorisch bekannte Handtuchrolle 2a, mit Bandmaterial 2, ist hier auf mehrere vertikale, kreis-konkav ausgeschnittene Lager-Rippen 4 eingelegt; eine weiter vorspringende Rippe 5, dient - beidseitig - als Träger und Lager für eine Achse 6 mit einer zylindrischen Umlenk-Rolle 7. Das Tuch 2 hängt, nach dem richtigen Einlegen mit seinem Anfangsteil 20 mit einer eingenähten Leiste 20' über eine erste Schwenkrolle 19 geführt, frei beweglich.A notoriously known towel roll 2a, with tape material 2, here is cut out on several vertical, circular-concave Bearing ribs 4 inserted; another projecting Rib 5, serves - on both sides - as a support and bearing for an axis 6 with a cylindrical deflection roller 7. The cloth 2 hangs with its after the correct insertion Start part 20 with a sewn-in bar 20 'over a first swivel castor 19 guided, freely movable.

Die einzige Achse 18 der Schwenkrolle 19 ist endseitig in je zwei, einander gegenüberliegenden, schwenkbaren Lager-Supports 17 gelagert, welche ihrerseits, zusammen mit einem inneren, hohlzylindrischen Führungselement 15 schwenkbar in Achse und Lager 26 in zwei Rollenträgern 16 geführt ist. Die Achse 26 treibt eine Wickelrolle 27 mit einer magnetischen Nut 25.The only axis 18 of the swivel roller 19 is at the end in Two swiveling bearing supports opposite each other 17 stored, which in turn, together with a inner, hollow cylindrical guide element 15 pivotable in Axis and bearing 26 is guided in two roller carriers 16. The axis 26 drives a winding roller 27 with a magnetic Slot 25.

Nach hinten gedreht ist hier eine zweite Schwenkrolle 11, mit Achse 12, welche mit ihrem Lager-Support 13 und einem äusseren Führungselement 14 ebenfalls um die Achse 26 drehbar ist.Turned backwards here is a second caster 11 with axis 12, which with their bearing support 13 and a outer guide element 14 is also rotatable about the axis 26 is.

Darunter befinden sich sogenannte Glätterollen 23 und 24, deren Achsen 21 bzw 22 in rechteckförmigen Rollenträgern 28 frei rotierbar gelagert sind.Underneath there are so-called smoothing rollers 23 and 24, whose axes 21 or 22 in rectangular roller carriers 28 are freely rotatable.

Wird eine saubere Handtuchrolle 2a auf die bogenförmigen Lager-Rippen 4 gelegt, so positioniert sich diese gemäss Fig. 1. Durch ein kurzes manuelles Ziehen am Anfangsteil 20 wird die ferromagnetische Leiste 20' in die ebensolche magnetische Nut 25 gezogen und festgehalten.Will a clean towel roll 2a on the arcuate Bearing ribs 4 placed, this is positioned according to Fig. 1. By a short manual pull on the beginning part 20th is the ferromagnetic strip 20 'in the same magnetic groove 25 pulled and held.

Dieser Vorgang ist in Fig. 1 durch zwei Pfeile charakterisiert.This process is characterized by two arrows in FIG. 1.

Durch ein darauffolgendes Schliessen des Deckels la mit Seitenwänden S, schwenken die Rollen 11 und 19 in die in Fig. 2 gezeichnete Lage; gleichzeitig wird eine im Deckel la mittels Lager-Supports 9 geführte Führungsrolle 8 in die gezeichnete Lage gebracht und auch die Achse 26 gedreht; wodurch die Rolle 27 - in Fig. 2 verdeckt, in Fig. 1 sichtbar - das Bandmaterial 2 bzw. 2' aufwickelt.By subsequently closing the lid la with Side walls S, the rollers 11 and 19 pivot into the in Fig. 2 drawn position; at the same time there is one in the lid la guided by means of bearing supports 9 guide roller 8 in the brought drawn position and also rotated the axis 26; whereby the roller 27 - covered in Fig. 2, visible in Fig. 1 - The tape material 2 or 2 'wound up.

Die beiden Führungselemente 14 und 15 ziehen auf ihrem Schwenkweg weiteres Bandmaterial nach, wodurch sich die in Fig. 2 angedeutete Schlaufe 3 bildet, die in bekannter Weise aus dem Apparategehäuse 1 hängt und dem Händetrocknen dient.The two guide elements 14 and 15 pull on their Swivel path after additional tape material, whereby the in Fig. 2 indicated loop 3 forms that in a known Hangs out of the apparatus housing 1 and drying hands serves.

Eine bevorzugte Art der Kraftübertragung vom Deckel la zur Schwenkvorrichtung ist in Fig. 3 dargestellt.A preferred type of power transmission from the lid la to Swivel device is shown in Fig. 3.

Gegenüber Fig. 1 ist hier ein zusätzlicher Betätigungshebel 30 ersichtlich, welcher in einer Ausnehmung 31 durch einen Schraubbolzen 34 mit Flansch geführt ist; sein linearer Verschiebweg ist durch einen Doppelpfeil charakterisiert. Auf einer Stirnseite weist der Hebel 30 eine Verzahnung 32 auf, welche in ein, auf der Achse 26 aufgesetztes Stirnrad 35 eingreift.Compared to Fig. 1 here is an additional operating lever 30 can be seen, which in a recess 31 by a Screw 34 is guided with flange; be linear Displacement is characterized by a double arrow. The lever 30 has teeth 32 on one end face on, which in a, on the axis 26 spur gear 35 engages.

Ein Schwenkhebel 44 ist an seinem hinteren Ende am Scharnier 1b gelagert und über einen Mitnehmer 33 mit dem Betätigungshebel 30 gekoppelt.A pivot lever 44 is at the rear end on the hinge 1b stored and via a driver 33 with the Actuating lever 30 coupled.

Die Betätigung des Schwenkhebels in Pfeilrichtung B, welcher, wie dargestellt, auch ohne Kopplung an einen Deckel 1a' realisierbar ist, resultiert somit in einem automatischen Einfädeln des Bandmaterials 2 sowie der Initiierung des Aufwickelns des benutzten Materials 2', (vgl. Fig. 2).The actuation of the pivot lever in the direction of arrow B, which as shown, also without coupling to a lid 1a 'is realizable, thus results in an automatic Threading the band material 2 and the initiation the winding of the used material 2 '(see FIG. 2).

Gleichzeitig bewirken die beiden Führungselemente 14 und 15 den notwendigen Auszug des Bandmaterials 2 zu einer Schlaufe und die Separierung von benutztem Bandmaterial 2' vom sauberem Material 2. At the same time, the two guide elements 14 and 15 the necessary extract of the tape material 2 to one Loop and separation of used strip material 2 ' of clean material 2.

Als Weg- und Zeitbegrenzung für die Tuchlänge können die allgemein bekannten Mittel verwendet werden, die zumeist mit Saugnäpfen und Sperrgliedern arbeiten.As a path and time limit for the length of the fabric, the generally known agents are used, mostly work with suction cups and locking members.

Es ist offensichtlich, dass - nach der vollständigen Benutzung der Rolle 2a zum Händetrocknen - durch ein Weiterbewegen des Betätigungshebels 30 bzw. des Schwenkhebels 44 über die im Betrieb übliche Position hinaus, dieser den restlosen Einzug des benutzten Bandmaterials 2' ermöglicht.It is obvious that - after full use the roller 2a for drying hands - by moving on of the operating lever 30 or the pivot lever 44 via the usual position in operation, this the remaining one The used strip material 2 'can be drawn in.

Der Antrieb des Hebels 30 kann in an sich bekannter Weise durch eine Feder oder einen Elektromotor erfolgen, welche aktiviert sind, wenn die Rolle 2a abgewickelt ist bzw. nicht mehr auf den Lager-Rippen 4 aufliegt.The lever 30 can be driven in a manner known per se by a spring or an electric motor, which are activated when roll 2a is unwound or no longer rests on the bearing ribs 4.

Die nachfolgend beschriebenen weiteren Varianten zur Ausgestaltung der Wickelrolle und des entsprechenden Anfangsteils des Tuchs sind je nach Antrieb des Spenders - manuell, elektrisch oder elektromechanisch mit elektronischer Steuerung - mehr oder weniger zweckmässig und adaptierbar auf den spezifischen Fall.The further design variants described below the winding roll and the corresponding initial part depending on the dispenser drive - manually, electrical or electromechanical with electronic Control - more or less appropriate and adaptable on the specific case.

Die rohrförmige Wickelrolle 27', Fig. 4 weist zwei einander gegenüberliegende Längsnuten 25' auf, welche eingangsseitig verbreitert sind. In die Nut 25' wir das Anfangsteil 20 mit seiner Leiste 20' eingeschoben und mit einem Mitnehmerflansch 36 mit einem Mitnehmer 38 versehen. Auf der Gegenseite erhält die Wickelrolle 27' einen Gegenflansch 37; beide Flansche sind durch eine Vierkantstange 39 mit einer Lagerstelle verbunden.The tubular winding roll 27 ', Fig. 4 has two each other opposite longitudinal grooves 25 'on the input side are widened. In the groove 25 'we with the starting part 20 its bar 20 'inserted and with a driver flange 36 provided with a driver 38. On the opposite side the winding roll 27 'receives a counter flange 37; both flanges are connected by a square rod 39 with a Depository connected.

Nach Fig. 5 besitzt die Wickelrolle 27" eine Vielzahl von Nuten, in welche das Anfangsteil 20", welches gemäss Fig. 5a gliederartig ausgestaltet ist, eingeschoben wird.5, the winding roll 27 "has a variety of Grooves into which the initial part 20 ", which according to Fig. 5a is designed like a link, is inserted.

Zur Erleichterung des Einschiebvorgangs dienen seitliche Führungsbleche 40, welche, wie angedeutet, durch Steuergestänge 41 lateral verschiebbar sind. Die notwendige Vorschubbewegung des Anfangsteils 20" erfolgt über zusätzliche Schieber 43, welche in Lamellen-Nuten 42 eingreifen.Lateral serve to facilitate the insertion process Guide plates 40 which, as indicated, by control linkage 41 are laterally displaceable. The necessary feed movement of the initial part 20 "is done via additional Slider 43 which engage in lamella grooves 42.

Der eigentliche Aufrollvorgang ist in Fig. 6 in den Phasen I bis IV dargestellt; aus Gründen der Übersichtlichkeit sind jeweils nur die im Einfädelvorgang aktiven Nuten 25" sowie die dazu benachbarten dargestellt; die Phase IV zeigt das reguläre Aufwickeln.The actual reeling process is in the phases in FIG. 6 I to IV shown; for reasons of clarity are only the grooves 25 "active in the threading process as well as the neighboring ones are shown; phase IV shows the regular winding.

Es hat sich gezeigt, dass ein fixes Anbringen des Bandmaterials 2' gemäss Fig. 5a beim Waschen (in entsprechenden Maschinen) Probleme ergeben kann, ebenso beim anschliessenden Heiss-Mangel. Es empfiehlt sich deshalb, das Teil mit den gliederartigen Leisten 20" über einen Klettenverschluss am Bandmaterial lösbar anzubringen.It has been shown that a fixed attachment of the tape material 2 'according to FIG. 5a during washing (in corresponding machines) Problems can arise, as with the subsequent one Hot shortage. It is therefore recommended that the part with the link-like strips 20 "via a Velcro fastener on Tape material releasably attached.

Besonders bewährt haben sich Wickeldorne nach Fig. 7 und Wickelfedern nach Fig. 8.Winding mandrels according to Fig. 7 and Coil springs according to FIG. 8.

Gemäss Fig. 7 befindet sich am noch sauberen Bandmaterial 2 ein Bund 2a' mit beidseitigen Schlaufen-Öffnungen mit einer Weite A der Schlaufen-Öffnung.7, the strip material 2 is still clean a collar 2a 'with loop openings on both sides with a Width A of the loop opening.

Dieser Bund 2a' lässt sich in einfacher Weise mittels Nähten als Saum 2b ausbilden und stört beim Waschen und Mangeln nicht.This collar 2a 'can be easily sewn form as hem 2b and disturbs washing and ironing Not.

Bei der Inbetriebnahme des Handtuchspenders wird somit ein Wickeldorn 27a in den Bund 2a' eingeschoben und die Achse 26 entsprechend positioniert. Der Wickeldorn 27a weist auf seiner Achse 26 Längs-Rippen 50 und Quer-Rippen 51 auf; zudem befindet sich rechtsseitig ein dem Transport dienendes Zahnrad, ein Stirnrad 35. When the towel dispenser is started up, a Winding mandrel 27a inserted into the collar 2a 'and the axis 26 positioned accordingly. The mandrel 27a has its axis 26 has longitudinal ribs 50 and transverse ribs 51; moreover there is a transport on the right side Gear, a spur gear 35.

Der Wickeldorn 27a gewährleistet einen einfachen und sicheren Beginn des Wickelvorgangs zur Bildung der Rolle mit dem benutzten Bandmaterial 2'.The winding mandrel 27a ensures simple and safe Start of the winding process to form the roll with the used tape material 2 '.

Die Variante gemäss Fig. 8 benötigt einen Bund 2a' von geringerer Weite A' und stellt dementsprechend eine günstige Weiterbildung zu Fig. 7 dar.The variant according to FIG. 8 requires a collar 2a 'of less Width A 'and accordingly represents a favorable Further development to Fig. 7.

Dabei wird eine Wickelfeder 27b verwendet, welche eine einfederbare Seitenfeder 52 aufweist, welche in einer Einfederungs-Sicke 53 axial beweglich ist. Das rechtsseitige auf der Achse 26 befestigte fixe Teil geht in eine kurze Schliessfeder 54 über und weist ein rundes (bombiertes) Endteil 55 auf.Here, a clock spring 27b is used, which is a spring-loaded Has side spring 52 which in a deflection bead 53 is axially movable. The right side on the fixed part of the axis 26 goes into a short Closing spring 54 and has a round (domed) End part 55 on.

Es hat sich gezeigt, dass mit einem sehr geringem manuellen Aufwand das automatische Einfädeln umgangen werden kann und dass die Betriebssicherheit des Handtuchspenders höher ist.It has been shown that with a very low manual Effort that automatic threading can be avoided and that the operational safety of the towel dispenser is higher.

Im weiteren ist bereits aus Fig. 1 bis 3 ersichtlich, dass sowohl die saubere Rolle 2a als auch das benutzte Bandmaterial in einfachster Weise in den Spender eingebracht bzw. aus diesem entfernt werden kann.Furthermore, it can already be seen from FIGS. 1 to 3 that both the clean roll 2a and the tape material used introduced into the dispenser in the simplest way or can be removed from this.

Denkbar ist auch ein gesteuerter, automatischer Auswurf der benutzten Rolle in einen dafür geeigneten Behälter.A controlled, automatic ejection of the used roll in a suitable container.
