Description

Die Erfindung betrifft einen Bodenwischer, welcher einen Träger zur Halterung eines an seiner Unterseite mit einer Vielzahl von Fransen od.dgl. besetzten Bezuges od.dgl. oder eines Hochflorwaschbezuges od.dgl. aufweist, welcher aus zwei Schenkeln sowie einem Mittelstück besteht, wobei die beiden Schenkel des Trägers an ihren einander zugewandten Stirnseiten schwenkbar mit dem Mittelstück verbunden sind und das Mittelstück mit einer mittig an diesem angebrachten Stielhalterung ausgerüstet ist.The invention relates to a floor wiper, or the like a carrier for holding a on its underside with a plurality of fringes. occupied cover or the like. or a deep pile wash cover or the like. has, which consists of two legs and a middle piece, the two legs of the carrier are pivotally connected to the middle piece on their mutually facing end faces and the middle piece is equipped with a handle holder attached centrally to this.

Bei einem bekannten derartigen Bodenwischer sind in den Schenkeln Schließeinrichtungen vorgesehen, welche eine Verriegelung zwischen dem Mittelteil und den schwenkbaren Schenkeln ermöglichen. Durch nach außen vorragende Zapfen ist es möglich, die Schließeinrichtung zu entriegeln, so daß die Schenkel in bezug auf das Mittelteil nach unten weggeklappt werden können und der mit Fransen od.dgl. versehene Bezug von den Schenkeln gelöst werden kann. Das erneute Befestigen des Bezuges und das Zurückschwenken der Schenkel des Trägers geschieht in umgekehrter Reihenfolge. Die Befestigung des Bezuges an den Enden der Schenkel erfolgt beispielsweise mittels bandförmiger Klettverschlüsse, die an den Schenkelenden angebrachte Ösen od.dgl. durchsetzen. Ein Nachteil dieses bekannten Bodenwischers besteht darin, daß dessen Schenkel gehäuseartig ausgebildet sein müssen, um die Schließeinrichtungen unterbringen zu können, was nicht nur einen vergleichsweise großen Aufwand in der Herstellung sondern auch in der Montage mit sich bringt. Ein weiterer Nachteil dieser bekannten Wischer liegt darin, daß diese zum Zusammen- und Auseinanderklappen in beide Hände genommen werden müssen, wobei einmal der Stiel sehr hinderlich ist und zum anderen eine starke Verschmutzungsgefahr besteht.In a known floor wiper of this type, locking devices are provided in the legs, which enable locking between the middle part and the pivotable legs. By outwardly projecting pins, it is possible to unlock the locking device, so that the legs can be folded down with respect to the central part and the like or with fringes. provided cover can be detached from the legs. The cover is reattached and the wearer's legs are swung back in reverse order. The cover is attached to the ends of the legs, for example, by means of band-shaped Velcro fasteners or the like attached to the ends of the legs. push through. A disadvantage of this known floor mop is that its legs have to be designed like a housing in order to accommodate the locking devices, which not only involves a comparatively great effort in manufacture but also in assembly. Another disadvantage of these known wipers is that they have to be taken in both hands for folding and unfolding, the handle being very cumbersome on the one hand and a high risk of contamination on the other hand.

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, unter Vermeidung vorerwähnter Nachteile einen Bodenwischer der eingangs genannten Art zu schaffen, welcher nicht nur in einfacher Weise herzustellen und zu montieren ist, sondern darüber hinaus auch eine schnelle, saubere und sichere Handhabung in bezug auf das Anbringen sowie das Abnehmen des mit Fransen od.dgl. besetzten Bezuges od.dgl. ermöglicht.Starting from this prior art, the invention has for its object to provide a floor mop of the type mentioned, which is not only easy to manufacture and assemble, but also quick, clean and safe handling in avoiding the aforementioned disadvantages with respect to attaching and detaching the like with fringes or the like. occupied cover or the like. enables.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Mittelstück eine mit den beiden Schenkeln schwenkbar verbundene Unterplatte aufweist, auf der eine Tragplatte befestigt ist, auf welcher eine Federscheibe drehbar angeordnet ist, auf der sich eine mit dieser verbundene Spannscheibe befindet, auf der die Stielhalterung befestigt ist, wobei auf den Oberseiten der beiden Schenkel vorgsehene Zugfedern zur Spannung derselben in Auskehlungen od.dgl. der Federscheibe geführt sind. Durch diese Ausgestaltung ist es möglich, durch einfaches Drehen des der Handhabung dienenden Stiels und damit der Spann- und der damit verbundenen Federscheibe um etwa 90 Grad eine Verriegelung der beiden Schenkel in ihrer waagerechten Arbeitslage zu bewirken bzw. eine Entriegelung, so daß diese von der Unterplatte aus nach unten wegklappen, wobei durch die Wirkung der Federn eine gewisse Spreizstellung der beiden Schenkel gewährleistet ist. Der nach unten durchhängende Bezug kann in einer Presse gesäubert werden, woraufhin durch Aufsetzen der leicht auseinander gespreizten Schenkel und Ausübung eines Druckes auf den Stiel deren Auseinanderschwenken in ihre waagerechte Lage erfolgt und durch Zurückdrehen des Stieles um 90 Grad deren Verriegelung in ihrer waagerechten Arbeitslage. Die Säuberung des Bezuges erfolgt üblicherweise in einem mit Wasser gefüllten Eimer, woraufhin dieser in einer Mop-Presse ausgedrückt wird. Durch diese Ausgestaltung ist es möglich, das Verspannen sowie Entriegeln der beiden Schenkel durch einfaches Drehen des Steieles um 90 Grad in die eine oder in die andere Drehrichtung zu bewirken. Die Ränder der beiden Schenkel und der Unterplatte besitzen vorzugsweise an ihren Längsseiten Aufbiegungen, welche von Lagerzapfen durchsetzt sind. Beide Bauteile weisen somit einen U-förmigen Querschnitt auf, so daß sich eine sehr flache Bauweise ergibt, da das Mittelstück und die übrigen noch benötigten Bauteile innerhalb der Höhe der Aufbiegungen angeordnet werden können. Die Unterplatte verhindert außerdem ein Hochschwenken der Schenkel des Trägers, da die Oberseiten der Schenkel flächig an der Unterseite der Unterplatte anliegen.According to the invention, this object is achieved in that the center piece has a lower plate pivotally connected to the two legs, on which a support plate is fastened, on which a spring washer is rotatably arranged, on which there is a tensioning disk connected to this, on which the handle holder is fastened is, provided on the top of the two legs tension springs for tensioning the same in grooves or the like. the spring washer are guided. With this configuration, it is possible to effect a locking of the two legs in their horizontal working position or an unlocking by simply turning the handle serving for handling and thus the tensioning washer and the associated spring washer, so that these can be unlocked from the Fold down the lower plate from below, whereby the action of the springs ensures a certain spreading position of the two legs. The sagging cover can be cleaned in a press, whereupon by placing the slightly spread legs and exerting pressure on the handle, they swivel apart into their horizontal position and by turning the handle back 90 degrees to lock it in its horizontal working position. The cover is usually cleaned in a bucket filled with water, after which it is squeezed out in a mop press. This configuration makes it possible to clamp and unlock the two legs by simply turning the handle through 90 degrees in one or the other direction of rotation. The edges of the two legs and the lower plate preferably have bends on their long sides which are penetrated by bearing pins. Both components thus have a U-shaped cross section, so that there is a very flat design, since the center piece and the other components still required can be arranged within the height of the bends. The lower plate also prevents the legs of the wearer from swinging up, since the upper sides of the legs lie flat against the underside of the lower plate.

Die folgenden Augaben betreffen besondere Ausführungsarten.The following issues relate to special designs.

Die Tragplatte ist mit mindestens einer Führungsbahn ausgerüstet, der ein Führeungsbolzen der darüber befindlichen Federscheibe zugeordnet ist. Die Führungsbahn ist von einer Nut gebildet, in die sich der Führungsbolzen der Federscheibe erstreckt. Die Führungsbahn ist viertelkreisförmig gestaltet. Somit ermöglicht die Führungsbahn ein Verdrehen der Federscheibe sowie der Spannscheibe um etwa 90 Grad, wobei die Stirkanten der Führungsnut jeweils einen Anschlag für den Führungsbolzen besitzen und damit eine sichere Arretierung gegeben ist.The support plate is equipped with at least one guideway to which a guide pin of the spring washer is assigned. The guideway is formed by a groove into which the guide pin of the spring washer extends. The guideway is designed in a quarter circle. The guideway thus enables the spring washer and the tensioning washer to be rotated by approximately 90 degrees, the end faces of the guide groove each having a stop for the guide bolt and thus ensuring a secure locking.

Die Spannscheibe ist ebenfalls kreisförmig ausgebildet und mit zwei einander gegenüberliegenden, vorragenden Ansätzen ausgerüstet, welche sich nach unten erstreckende Rastbolzen tragen. Die Rastbolzen sind im wesentlichen kugelförmig ausgeführt.The clamping washer is also circular and equipped with two mutually opposite, projecting lugs which carry locking bolts extending downwards. The locking bolts are essentially spherical.

Auf den Oberseiten der Schenkel ist beiderseits des Mittelstückes je eine Rastaufnahme vorgesehen, welche den Rastbolzen der Spannscheibezugeordnet sind, so daß diese in der Verspannungslage der Spann- sowie der Federscheibe in diese einrasten und damit die waagerechte Arbeitsposition der beiden Schenkel gewährleistet ist. Die Rastaufnahmen sind quer zur Längsrichtung der Schenkel verlaufend, etwa in deren mittlerem Bereich, angebracht. Durch die Drehbewegung der Spannscheibe um 90 Grad werden die Rastbolzen aus der Entriegelungslage durch Drehen um 90 Grad in die Rastaufnahmen eingeschwenkt unter gleichzweitiger Spannung der Zugfedern. Die Rastaufnahmen selbst sind im Querschnitt etwa U-förmig ausgebildet und besitzen etwa in ihren mittleren Bereichen Ausbuchtungen, welche als Führungsbahnen für die Rastbolzen dienen. In den Ausbuchtungen der Rastaufnahmen sind in deren mittleren Bereichen Bohrungen vorgesehen, welche der Kugelform der Rastbolzen angepaßt sind, so daß diese in der Spannlage in diese Bohrungen einrasten.On the top of the thigh is on both sides of the center piece, a snap-in receptacle is provided, which is assigned to the locking bolts of the tensioning washer, so that they snap into the tensioned position of the tensioning washer and the spring washer, thereby ensuring the horizontal working position of the two legs. The snap-in receptacles are arranged transversely to the longitudinal direction of the legs, for example in the central area thereof. Due to the rotating movement of the tensioning disc by 90 degrees, the locking bolts are swiveled out of the unlocking position by turning them through 90 degrees into the locking receptacles while simultaneously tensioning the tension springs. The locking receptacles themselves are approximately U-shaped in cross section and have bulges in their central areas, which serve as guideways for the locking bolts. In the bulges of the snap-in receptacles, holes are provided in their central areas, which are adapted to the spherical shape of the snap-in bolts so that they snap into these holes in the clamping position.

In den Auskehlungen od.dgl. der Federscheibe sind um 180 Grad versetzt zueinander die einen Enden zweier Zugfedern befestigt, deren andere Enden jeweils an einem Bock festgelegt sind, welche sich auf den Oberseiten der Schenkel befinden. Die Anordnung der Zugfedern ist derart, daß diese in ihren Spannlagen die Federscheibe mindestens auf einem Umfang von etwa 90 Grad umschlingen und dann in etwa geradlinig zu den Böcken verlaufen. In der Entriegelungslage der Spannscheibe sowie der Federscheibe begrenzen die Zugfedern das Wegklappen der beiden Schenkel des Trägers nach unten, so daß ein bestimmter gewünschter Öffnungswinkel der beiden Schenkel zueinander immer vorhanden ist.In the grooves or the like. the spring washer are offset by 180 degrees to each other, one end of two tension springs are attached, the other ends of which are each fixed to a bracket, which are located on the upper sides of the legs. The arrangement of the tension springs is such that in their tensioned positions they wrap around the spring washer at least over a circumference of approximately 90 degrees and then run approximately in a straight line to the trestles. In the unlocked position of the spring washer and the spring washer, the tension springs limit the folding away of the two legs of the carrier downward, so that a certain desired opening angle of the two legs to one another is always present.

Gemäß einem weiteren Vorschlag können die Feder- und die Spannscheibe zu einem Beauteil vereinigt sein. In diesem Falle besteht die Feder-und Spannscheibe aus einem im wesentlichen rechteckförmigen Riegel, welcher an seinen äußeren Stirnkanten die Auskehlung od.dgl. aufweist, wobei diesem zwei parallel zueinander verlaufende Zugfedern zugeordnet, deren Enden jeweils auf den Oberseiten der beiden Schenkel befestigt sind, und deren Mittelabschnitte in der Auskehlung od.dgl. des Riegels geführt sind. Diese Ausführung ist besonders einfach, da die Anzahl der Bauteile des Mittelstückes weiter reduziert ist. Die Betätigung erfolgt in der Weise, daß durch Drehen des Stiels um 90 Grad durch Spreizung der beiden Zugfedern deren Verspannung bewirkt wird, so daß die Schenkel des Trägers in ihrer waagerechten Arbeitslage fixiert sind, während durch Weiterdrehen oder Zurückdrehen um 90 Grad die Spreizung der Zugfedern aufgehoben wird, da nunmehr die Mittelabschnitte der Federn an den Längsseiten des Riegels anliegen, so daß die Verriegelung aufgehoben ist und die beiden Schenkel nach unten hin wegklappen können.According to a further proposal, the spring washer and the spring washer can be combined to form one component. In this case, the spring and spring washer consists of an essentially rectangular bolt, which has the groove or the like on its outer end edges. has, associated with this two parallel tension springs, the ends of which are each attached to the top of the two legs, and the middle portions or the like in the groove. of the bolt are led. This version is particularly simple since the number of components of the center piece is further reduced. The actuation is carried out in such a way that by rotating the handle 90 degrees by spreading the two tension springs, the bracing is effected so that the legs of the carrier are fixed in their horizontal working position, while by further turning or turning back 90 degrees the spread of the tension springs is lifted, since now the middle sections of the springs rest on the long sides of the bolt, so that the lock is released and the two legs can fold down towards the bottom.

Um die Handhabung des Bodenwischers vorgenannter Art weiter zu verbessern, wird vorgeschlagen, daß die Federscheibe und/oder die Spannscheibe im Bereich ihrer äußeren Umfläche bzw. Umflächen mindestens eine Kerbe, Nut od.dgl. aufweist bzw. aufweisen und dieser Kerbe, Nut od.dgl. das freie Ende des einen Armes eines doppelarmigen Hebels zugeordnet ist, welcher auf einem Schenkel schwenkbar gelagert ist, und dessen anderer Arm derart unter der Einwirkung einer Feder steht, daß das freie Ende des einen Armes des doppelarmigen Hebels gegen die äußere Umfläche bzw. äußeren Umflächen der Federscheibe und/oder der Spannscheibe anliegende gehalten ist. Auf diese Weise ist eine sichere Festlegung der Feder- und Spannscheibe in der Gebrauchslage des Bodenwischers gewährleistet, da das freie Ende des einen Armes des doppelarmigen Hebels formschlüssig in die Kerbe, Nut od.dgl. der Federscheibe und/oder der Spannscheibe einrastet. Somit ist es nicht möglich, die Gebrauchslage des Bodenwischers, also die waagerechte Position der beiden Schenkel, durch die Benutzung desselben aufzuheben. Hierzu bedarf es vielmehr der Ausübung einer Kraft auf den anderen, unter der Einwirkung einer Feder stehenden Arm des doppelarmigen Hebels, so daß dieser entgegen der Wirkung der Feder eine Verschwenkung erfährt derart, daß das freie Ende des einen Armes aus der Kerbe, Nut od.dgl. der Feder- und/oder der Spannscheibe herausgeschwenkt wird und diese freigibt. Nunmehr kann durch Verdrehen der Stielhalterung die Gebrauchslage des Bodenwischers afgehoben werden, so daß die beiden Schenkel desselben unter der Einwirkung der Zugfedern eine Schwenkbewegung nach unten hin ausführen.In order to further improve the handling of the floor wiper of the aforementioned type, it is proposed that the spring washer and / or the tensioning disk or at least one notch, groove or the like in the area of its outer peripheral surface or peripheral surfaces. has or have and this notch, groove or the like. the free end of one arm of a double-armed lever is assigned, which is pivotally mounted on one leg, and the other arm is under the action of a spring such that the free end of one arm of the double-armed lever against the outer peripheral surface or outer peripheral surfaces the spring washer and / or the spring washer is held. In this way, a secure fixing of the spring and spring washer in the position of use of the floor wiper is ensured, since the free end of one arm of the double-armed lever form-fit in the notch, groove or the like. the spring washer and / or the spring washer clicks into place. It is therefore not possible to cancel the position of use of the floor mop, that is to say the horizontal position of the two legs, by using the same. Rather, this requires the application of a force on the other, under the action of a spring arm of the double-armed lever, so that it experiences a pivoting against the action of the spring such that the free end of one arm from the notch, groove or. the like the spring and / or the spring washer is pivoted out and releases it. Now the position of use of the floor wiper can be lifted by turning the handle holder, so that the two legs of the floor wiper perform a swiveling movement downwards under the action of the tension springs.

Gemäß einem weiteren Vorschlag besitzen die Aufbiegungen an den Rändern der Längsseiten der beiden Schenkel an den Endbereichen derselben Ausnehmungen, so daß es möglich ist, im herabgeklappten Zustand der Schenkel und damit durchhängendem Bezug diesen in eine Presse einzugeben, so daß dieser über seine ganze Länge wirkungsvoll ausgedrückt und damit gesäubert werden kann.According to a further proposal, the bends on the edges of the long sides of the two legs at the end regions of the same recesses, so that it is possible to insert the legs in the folded state and thus sagging cover into a press, so that it is effective over its entire length expressed and can be cleaned with it.

Vorteilhaft sind die Ränder der beiden Schenkel an ihren Querseiten mit Hochbiegungen ausgerüstet, welche in ihrer Höhe geringfügig bemessen sind und etwa rechtwinklig verlaufen. Auf diese Weise ergibt sich ein Abrolleffekt beim Verschwenken der Schenkel auf der Innenseite des Bezuges, was das Spannen desselben zur Erreichung der Gebrauchslage des Bodenwischers sehr erleichtert.The edges of the two legs are advantageously equipped on their transverse sides with upward bends which are slightly dimensioned in height and run approximately at right angles. In this way, there is a rolling effect when pivoting the legs on the inside of the cover, which makes it very easy to tension the same to achieve the position of use of the floor wiper.

Nach einem weiteren Vorschlag ist in der Unterplatte des Wischers im Bewegungsbereich mindestens eines Rastbolzens eine Mehrkantbohrung vorgesehen, in die ein entsprechend mehrkantig gestalteter Fuß eines Bolzens einsteckbar ist, von dem ein Hals in den mehrkantigen Kopf des Bolzens vorzugsweise exzentrisch übergeht. Mindestens der Hals des Bolzens ist aus begrenzt elastischem Material hergestellt. Der Kopf des Bolzens kann zusätzlich mit einem oder mehreren in seiner Einsteckrichtung verlaufenden Einschnitten versehen sein, um die Elastizität zu erhöhen. Durch die Anbringung des Mehrkantbolzens im Verschwenkbereich mindestens eines der Rastbolzen wird eine Sicherung der Spannscheibe und damit des drehbaren Teils des Bodenwischers gegen unbeabsichtigtes Zurückdrehen erreicht. Nach der Reinigung des Bezuges hängen die beiden Schenkel des Bodenwischers nach unten herunter, wobei diese unter der Einwirkung der Zugfedern einen geringen Winkel zueinander einschließen. Bei Drehen des Stieles des Bodenwischers werden die Federn gespannt, wobei die Rastbolzen der Spannscheibe nach einem bestimmten Winkelbereich den eingesteckten Mehrkantbolzen infolge dessen Elastizität zur Seite drückt und sich hinter diesem befindet, so daß die beiden Schenkel sich in stärker gespreizter Position zueinander befinden. In dieser Position der Schenkel können diese sehr leicht in ihre waagerechte Lage und damit in die Gebrauchsstellung des Bodenwischers gedrückt werden, da der Bodenwischer an einem Verdrehen und damit der Rückkehr des Schenkel in ihrefederentlastete Lage gehindert ist. Durch diese Ausgestaltung wird die Handhabung des Bodenwischers ganz erheblich erleichtert, und zwar in bezug aus das Spannen der beiden Schenkel von ihrer abwärts geschwenkten Position in die waagerechte Gebrauchslage.According to a further proposal, a polygonal bore is provided in the lower plate of the wiper in the range of motion of at least one locking pin, into which a correspondingly polygonal foot of a pin can be inserted, from which a neck preferably merges eccentrically into the polygonal head of the pin. At least the neck of the bolt is made of limited elastic material. The head of the bolt can additionally be provided with one or more incisions running in its insertion direction in order to increase the elasticity. By attaching the polygonal bolt In the pivoting area of at least one of the locking bolts, the tensioning disk and thus the rotatable part of the floor wiper are secured against unintentional turning back. After cleaning the cover, the two legs of the floor wiper hang down, enclosing a small angle to each other under the action of the tension springs. When the handle of the floor wiper is turned, the springs are tensioned, the locking bolts of the tensioning disc pushing the inserted polygonal bolt to the side as a result of its elasticity after a certain angular range and being behind it, so that the two legs are in a more spread position relative to one another. In this position of the legs, they can be pressed very easily into their horizontal position and thus into the use position of the floor wiper, since the floor wiper is prevented from twisting and thus the leg from returning to its spring-released position. With this configuration, the handling of the floor wiper is made considerably easier, specifically with regard to the tensioning of the two legs from their downwardly pivoted position into the horizontal position of use.

Der Hals des Bolzens mündet exzentrisch in den Kopf desselben ein, so daß sich durch Verdrehen des Bolzens verschieden Abstände des Kopfes zu dem Rastbolzen einstellen lassen, und zwar durch einfaches Umstecken desselben.The neck of the bolt opens eccentrically into the head of the same, so that different distances of the head from the locking bolt can be set by rotating the bolt, by simply repositioning it.

Aus der FR-A-2 282 252 ist ein Bodenwischer bekannt, bei dem an einer mit dem Stiel starr verbundenen Montageplatte die den Träger für den Bezug bildenden Schenkel schwenkbar angelenkt sind. Diese beiden Schenkel werden durch eine mit ihnen und der Montageplatte verbundene Federeinrichtung in eine Stellung vorgespannt, in der sie den Bezug in seiner Reinigungsstellung halten. Zur Entsprannung des Bezugs, die u.a. gegen die Kraft der die Schenkel vorspannenden Federeinrichtung durchgeführt werden muß, ist dort eine durch eine Seilzugvorrichtung betätigte Spann- bzw. Entspanneinrichtung vorgesehen. Der Seilzug wird am Stiel über eine Hülse od. dergleichen betätigt. Die Spann- bzw. Entspanneinrichtung ist ihrerseits durch eine Spiralfeder oder dgl. so vorgespannt, daß sie die Bewegung des Bezugs in dessen Reinigungsstellung unterstützt, sobald sie nicht mehr durch die Seilzugvorrichtung beaufschlagt ist.A floor wiper is known from FR-A-2 282 252, in which the legs forming the support for the cover are pivotably articulated on a mounting plate rigidly connected to the handle. These two legs are biased by a spring device connected to them and the mounting plate into a position in which they hold the cover in its cleaning position. To correspond to the cover, which i.a. against the force of the spring device prestressing the legs, there is provided a tensioning or relaxing device actuated by a cable pulling device. The cable is operated on the handle via a sleeve or the like. The tensioning or relaxing device is in turn biased by a spiral spring or the like so that it supports the movement of the cover in its cleaning position as soon as it is no longer acted upon by the cable pulling device.

Der Bodenwischer weist einen Träger 1 zur Halterung eines an seiner Unterseite mit einer Vielzahl von Fransen od.dgl. besetzten Bezuges 2 auf, welcher in herkömmlicher Weise um die Endkanten 3 des Trägers gelegt ist, und mittels eines Klettverschlusses 4 od.dgl. auf den Oberseiten der beiden Schenkel 5, 6 lösbar befestigt ist.The floor wiper has a carrier 1 for holding one or the like on its underside with a plurality of fringes. occupied cover 2, which is placed in a conventional manner around the end edges 3 of the carrier, and by means of a Velcro 4 or the like. is releasably attached to the tops of the two legs 5, 6.

Der Träger 1 besteht aus den beiden Schenkeln 5, 6 sowie dem Mittelstück 7.The carrier 1 consists of the two legs 5, 6 and the center piece 7.

In Figur 1 und 2 sind mit 8 die Unterbrechungslinien bezeichnet, da der Träger 1 der besseren Übersichtlichkeit halber nicht in seiner ganzen Länge dargestellt werden konnte. In Figur 2 ist außerdem der Bezug 2 weggelassen, um den Träger 1 deutlicher zeigen zu können.In FIGS. 1 and 2, the break lines are designated by 8, since the carrier 1 could not be shown in its entire length for the sake of clarity. In Figure 2, the reference 2 is also omitted in order to show the carrier 1 more clearly.

Das Mittelstück 7 weist eine Unterplatte 9 auf, welche auf den Oberseiten der beiden Schenkel 5, 6 des Trägers 1 aufliegt und wie diese im Querschnitt U-förmig ausgebildet ist, wobei sowohl die Schenkel 5, 6 als auch die Unterplatte 9 an ihren Längsseiten Aufbiegungen besitzen. Die Aufbiegungen werden von Lagerzapfen 10 durchsetzt, mit denen die beiden Schenkel 5, 6 einerseits und die Unterplatte 9 andererseits schwenkbar miteinander verbunden sind.The center piece 7 has a lower plate 9, which rests on the upper sides of the two legs 5, 6 of the carrier 1 and how this is U-shaped in cross section, with both the legs 5, 6 and the lower plate 9 bending up on their long sides have. The bends are penetrated by journals 10 with which the two legs 5, 6 on the one hand and the lower plate 9 on the other hand are pivotally connected to one another.

Auf der Unterplatte 9 ist eine Tragplatte 11 befestigt, die kreisförmigen oder aber auch rechteckförmigen Querschnitt besitzen kann, wie aus Figur 3 ersichtlich ist. Die Befestigung der Tragplatte 11 auf der Unterplatte 9 kann durch Schraubung, Nietung od.dgl. erfolgen. Die Tragplatte 11 ist im dargestellten Falle mit zwei Führungsbahnen 12 ausgerüstet, welche je von einer Nut gebildet und viertelkreisförmig ausgeführt sind, d.h. diese erstrecken sich um einen Winkel von etwa 90 Grad. In ihrem mittleren Bereich weist die Tragplatte eine Gewindebohrung 13 auf.A support plate 11 is fastened on the lower plate 9 and can have a circular or rectangular cross section, as can be seen from FIG. 3. The attachment of the support plate 11 on the lower plate 9 or the like by screwing, riveting. respectively. The support plate 11 is equipped in the case shown with two guideways 12, each formed by a groove and designed in a quarter circle, i.e. these extend through an angle of approximately 90 degrees. In its central area, the support plate has a threaded bore 13.

Auf der Tragplatte 11 ist die Federscheibe 14 drehbar angeordnet, deren Ausgestaltung sich aus Figur 4 und 5 ergibt. Im mittleren Bereich der Federscheibe 14 ist ein nach unten vorragender Gewindebolzen 15 vorhanden, mit welchem diese um einige Gewindegänge in die Gewindebohrung 13 der Tragplatte eingeschraubt ist, so daß einmal eine Befestigung gegeben ist und zum anderen eine Drehbarkeit der Federscheibe 14 gegenüber der Tragplatte 11. Diese Drehbarkeit ist begrenzt auf einen Winkel von etwa 90 Grad. Zu diesem Zwecke erstreckt sich ein oder je ein Führungsbolzen 16 in eine oder je eine Führungsbahn 12 der Tragplatte 11. Die Stirnkanten der Führungsbahnen 12 begrenzen dann die Drehbewegung der Federscheibe 14.The spring washer 14 is rotatably arranged on the support plate 11, the design of which is shown in FIGS. 4 and 5. In the central area of the spring washer 14 there is a threaded bolt 15 projecting downwards, by means of which it is screwed into the threaded bore 13 of the support plate by a few thread turns, so that there is fastening once and on the other hand a rotation of the spring washer 14 with respect to the support plate 11. This rotatability is limited to an angle of approximately 90 degrees. For this purpose, one or each guide pin 16 extends into one or each guide track 12 of the support plate 11. The end edges of the guide tracks 12 then limit the rotational movement of the spring washer 14.

Die Federscheibe 14 ist kreisförmig ausgebildet und besitzt an ihrer äußeren Stirnkante die Auskehlung 17, deren Funktion nachfolgend noch beschrieben ist.The spring washer 14 is circular and has the groove 17 on its outer end edge, the function of which will be described below.

Auf der Federscheibe 14 ist die Spannscheibe 18 angebracht, wobei diese durch Schraubung, Nietung od.dgl. miteinander verbunden sind. Die Spannscheibe 18 (Figur 6) ist ebenso wie die Federscheibe 14 kreisförmig ausgebildet. An zwei einander gegenüberliegenden Bereichen ihres Umfanges ist die Spannscheibe 18 mit vorragenden Ansätzen 19 ausgerüstet, welches sich nach unten erstreckende Rastbolzen 20 tragen. Diese sind im wesentlichen kugelförmig ausgeführt.On the spring washer 14, the spring washer 18 is attached, this or the like by screwing, riveting. are interconnected. The tensioning disk 18 (FIG. 6), like the spring washer 14, is circular. On two mutually opposite areas of its circumference, the tensioning disk 18 is equipped with protruding projections 19 which carry locking bolts 20 which extend downwards. These are essentially spherical.

Auf den Oberseiten der Schenkel 5, 6 ist beiderseits des Mittelstückes je eine Rastaufnahme 21 (Figur 7 und 8) vorgesehen, welche den Rastbolzen 20 der Spannscheibe 18 zugeordnet sind. Die Rastaufnahmen 21 sind quer zur Längsrichtung der Schenkel 5, 6 verlaufend, etwa in deren mittleren Bereichen, angebracht. Die Rastaufnahmen 21 sind im Querschnitt etwa U-förmig ausgebildet und bestizen etwa in ihren mittleren Bereichen Ausbuchtungen 22. In den mittleren Bereichen dieser Ausbuchtungen 22 der Rastaufnahmen 21 sind Bohrungen 23 vorgesehen.On the upper sides of the legs 5, 6 there is a catch receptacle 21 (FIGS. 7 and 8) on both sides of the middle piece, which are assigned to the catch bolts 20 of the tensioning disk 18. The snap-in receptacles 21 are mounted transversely to the longitudinal direction of the legs 5, 6, approximately in their central regions. The latching receptacles 21 are approximately U-shaped in cross section and have bulges 22 approximately in their central regions. Bores 23 are provided in the central regions of these bulges 22 of the latching receptacles 21.

In den Auskehlungen 17 der Federscheibe 14 sind um 180 Grad versetzt zueinander die einen Enden 24 zweier Zugfedern 25 befestigt, deren andere Enden 26 jeweils an einem Bock 27 festgelegt sind, welche sich auf den Oberseiten der Schenkel 5, 6 befinden. Zu diesem Zwecke durchsetzen die Enden 26 der Zugfedern 25 Bohrungen der Böcke 27 und sind auf deren Rückseiten mittels Splinten od.dgl. gesichert. Die Anordnung der Zugfedern 25, welche aus schraubenlinienförmig gewickelten Drähten bestehen, ist derart, daß diese in ihren Spannlagen, wie sie aus Figur 1 und 2 ersichtlich sind, die Federscheibe 14 mindestens auf einem Umfang von etwa 90 Grad umschlingen und dann in etwa geradlinig zu den Böcken 27 verlaufen.In the grooves 17 of the spring washer 14, one end 24 of two tension springs 25 are fixed offset from one another by 180 degrees, the other ends 26 of which are each fixed to a bracket 27, which are located on the upper sides of the legs 5, 6. For this purpose, the ends 26 of the tension springs 25 pass through the bores of the brackets 27 and are or the like on the rear sides by means of split pins. secured. The arrangement of the tension springs 25, which consist of helically wound wires, is such that in their tensioning positions, as can be seen in FIGS. 1 and 2, they wrap around the spring washer 14 at least over a circumference of approximately 90 degrees and then approximately in a straight line the goats 27 run.

Wie aus Figur 2 ersichtlich, ist auf der Spannscheibe 18 die Stielhalterung 28 befestigt, welche ein Scharnier 29 aufweist, dessen Gelenkteil 30 über die Schwenkachse 31 mit dem Ansatz 32 des Stieleinsatzes 33 schwenkbar verbunden ist, so daß eine Verschwenkung des Stieleinsatzes 33 jeweils um 180 Grad um das Scharnier 29 sowie die Schwenkachse 31 in zwei um 90 Grad zueinander verlaufenden Ebenen möglich ist. In der waagerechten Lage der beiden Schenkel 5, 6 des Trägers 1 verläuft die Schwenkachse des Scharniers 29 der Stielhalterung 28 in Längsrichtung des Trägers 1. Dies stellt die Arbeitslage des Bodenwischers dar, so daß der Stiel zum Arbeiten mit dem Bodenwischer in die erforderlichen Lagen verschwenkt werden kann.As can be seen from FIG. 2, the stem holder 28 is fastened to the tensioning disk 18 and has a hinge 29, the joint part 30 of which is pivotally connected to the shoulder 32 of the stem insert 33 via the pivot axis 31, so that the stem insert 33 is pivoted by 180 in each case Degree around the hinge 29 and the pivot axis 31 in two planes running at 90 degrees to each other is possible. In the horizontal position of the two legs 5, 6 of the carrier 1, the pivot axis of the hinge 29 of the handle holder 28 runs in the longitudinal direction of the carrier 1. This represents the working position of the floor wiper, so that the handle pivots into the required positions for working with the floor wiper can be.

Die Wirkungsweise der erfindungsgemäßen Vorrichtung ist wie folgt:The operation of the device according to the invention is as follows:

In der aus Figur 1 und 2 ersichtlichen Lage befindet sich der Träger 1 des Bodenwischers in seiner Arbeitslage, in welcher die beiden Schenkel 5, 6 des Trägers 1 in einer waagerechten Ebene miteinander sowie mit dem Mittelstück 7 verspannt sind. Hierbei sind die Rastbolzen 20 der Spannscheibe 18 in die Rastaufnahmen 21 eingeschwenkt und durch deren Bohrungen 23 arretiert. Die Zugfedern 25 umschlingen die Federscheibe 14 jeweils um einen Umschlingungsreich von etwa 90 Grad und sind hierbei gespannt.In the position shown in FIGS. 1 and 2, the carrier 1 of the floor wiper is in its working position, in which the two legs 5, 6 of the carrier 1 are clamped to one another and to the center piece 7 in a horizontal plane. Here, the locking bolts 20 of the clamping disk 18 are pivoted into the locking receptacles 21 and locked by the bores 23. The tension springs 25 wrap around the spring washer 14 in each case by a looping range of approximately 90 degrees and are tensioned here.

Durch Drehen der Stielhalterung 28 um 90 Grad in der aus Figur 1 und 2 ersichtlichen Position nach links verlassen die Rastbolzen 20 die Rastaufnahmen 21 unter gleichzeitiger Entspannung der Zugfedern 25, so daß die beiden Schenkel 5, 6 des Trägers 1 unter ihrem Eigengewicht sowie dem des an diesem befestigten Bezuges 2 nach unten verschwenken können. Die Länge der Zugfedern 25 in Verbindung mit der Anordnung der Arretierungsböcke 27 begrenzt die Schwenkbewegung nach unten, so daß diese beispielsweise nicht um 180 Grad nach unten klappen können und damit etwa parallel zueinander liegen, sondern es verbleibt ein gewünschter Öffnungswinkel zwischen den freien Enden der beiden Schenkel 5, 6. Nunmehr wird der nach unten durchhängende Bezug 2 in einen Eimer mit Wasser getaucht und ausgespült, woraufhin das Auspressen mittels einer Presse erfolgt.By turning the handle holder 28 by 90 degrees in the position shown in Figures 1 and 2 to the left, the locking pins 20 leave the locking receptacles 21 while simultaneously releasing the tension springs 25, so that the two legs 5, 6 of the carrier 1 under their own weight and that of can pivot down on this attached cover 2. The length of the tension springs 25 in connection with the arrangement of the locking blocks 27 limits the pivoting movement downward, so that they cannot fold down, for example, by 180 degrees and thus lie approximately parallel to one another, but a desired opening angle remains between the free ends of the two Legs 5, 6. Now the downwardly sagging cover 2 is immersed in a bucket of water and rinsed out, whereupon the pressing takes place by means of a press.

Der Täger wird nunmehr auf den Boden auggesetzt, wobei sich dessen beide Schenkel 5, 6 aufgrund des vorhandenen Öffnungswinkels durch Ausüben von Druck auf die Stielhalterung 28 und damit auf das Mittelstück auseinanderspreizen, unter gleichzeitiger Spannung des Bezuges 2. Durch Verdrehen der Stielhalterung nach rechts um 90 Grad ergibt sich wieder die aus Figur 1 und 2 ersichtliche Verspannungslage.The hunter is now placed on the floor, the two legs 5, 6 of which spread apart due to the existing opening angle by exerting pressure on the handle holder 28 and thus on the middle piece, while simultaneously tensioning the cover 2. By turning the handle holder to the right 90 degrees again results in the tension position shown in FIGS. 1 and 2.

Die gesamte Handhabung des Bodenwischers geschieht durch Erfassen des nicht weiter dargestellten Stiels, wobei entweder eine Drehbewegung desselben um 90 Grad in der einen oder anderen Richtung ausgeführt wird oder aber die Ausübung von Druck, um das Auseinanderspreizen der beiden Schenkel 5, 6 zu bewirken.The entire handling of the floor mop is done by grasping the handle, not shown, either by rotating it 90 degrees in one direction or the other, or by applying pressure to cause the two legs 5, 6 to spread apart.

Infolge der Elastizität der verwendeten Zugfedern 25 ist es auch möglich, die Drehbewegung der Stielhalterung 28 in noch heruntergeklappter Lage der beiden Schenkel 5, 6 auszuführen, woraufhin durch Strecken der beiden Schenkel 5, 6 das Einrasten der Rastbolzen 20 in die Rastaufnahmen 21 erfolgt.As a result of the elasticity of the tension springs 25 used, it is also possible to carry out the rotary movement of the handle holder 28 in the folded-down position of the two legs 5, 6, whereupon the latching bolts 20 snap into the latching receptacles 21 by stretching the two legs 5, 6.

Wie aus Figur 9 und 10 ersichtlich ist es möglich, die Feder- 14 und Spannscheibe 18 zu einem rechteckförmigen Riegel 34 zu vereinigen. Der Riegel 34 weist an seiner äußeren Stirkante die Auskehlung 17 auf sowie den mittig vorgesehenen Gewindebolzen 15 zur Befestigung an der Grundplatte 11. Bei Verwendung des Riegels 34 finden zwei parallel zueinander angeordnete Zugfedern Verwendung, welche sich in Längsrichtung des Trägers 1 erstrecken. Deren Enden sind jeweils in Lagerböcken festgelegt. Die Mittelabschnitte der Federn verlaufen in der Auskehlung 17 des Riegels 34 und liegen in der Entriegelungslage des Trägers 1 an dessen Längsseiten an und in der Verriegelungslage der Schenkel 5, 6 des Trägers 1 an dessen Querseiten, so daß diese gespreizt werden.As can be seen from FIGS. 9 and 10, it is possible to combine the spring washer 14 and tensioning washer 18 to form a rectangular bolt 34. The bolt 34 has on its outer front edge the groove 17 and the centrally provided threaded bolt 15 for attachment to the base plate 11. When the bolt 34 is used, two tension springs arranged parallel to one another are used, which extend in the longitudinal direction of the carrier 1. The ends of each are fixed in bearing blocks. The central sections of the springs run in the groove 17 of the bolt 34 and lie in the unlocked position of the carrier 1 on its longitudinal sides and in the locked position of the legs 5, 6 of the carrier 1 on its transverse sides, so that these are spread apart.

Die Handhabung des Bodenwischers ist die gleiche wie vorbeschrieben, jedoch brauchen keine Anschläge zur Begrenzung der Drehbewegung vorhanden zu sein, sondern die Stielhalterung kann in einer Richtung jeweils um 90 Grad fortlaufend gedreht werden.The handling of the floor wiper is the same as described above, but there is no need to have stops to limit the rotary movement, but the handle holders tion can be rotated continuously in one direction by 90 degrees.

Bei den Ausführungen gemäß Figur 11-14 finden für gleiche Bauteile die gleichen Bezugszeichen Verwendung, wie bei der Ausführung gemäß Figur 1-10.In the designs according to FIGS. 11-14, the same reference numerals are used for the same components as in the designs according to FIGS. 1-10.

Wie aus Figur 11 und Figur 13 ersichtlich, kann die Spannscheibe 18 im Bereich ihrer äußeren Umfläche mit einer Kerbe 50 versehen sein. Der Kerbe 50 ist das freie Ende des einen Armes 51 eines doppelarmigen Hebels 52 zugeordnet, welcher auf dem Schenkel 5 mittels des Lagerbokkes 53 schwenkbar gelagert ist. Der andere Arm 54 steht derart unter der Einwirkung einer Feder 55, daß das freie Ende des einen Armes 51 gegen die äußere Umfläche der Spannscheibe 18 anliegend gehalten ist. Bei vorstehender Kerbe 50 rastet das freie Ende des einen Armes 51 in diese ein, so daß die Spannscheibe 18 gegen Verdrehen gesichert ist. Diese Arretierung läßt sich nur dadurch beseitigen, daß eine Kraft auf den anderen Habelarm 54 durch Drücken desselben entgegen der Wirkung der Feder 55 ausgeübt wird, so daß der eine Arm 51 aus der Kerbe 50 herausschwenkt.As can be seen from FIG. 11 and FIG. 13, the tensioning disk 18 can be provided with a notch 50 in the region of its outer peripheral surface. The notch 50 is associated with the free end of one arm 51 of a double-armed lever 52, which is pivotably mounted on the leg 5 by means of the bearing block 53. The other arm 54 is under the action of a spring 55 such that the free end of one arm 51 is held against the outer circumferential surface of the tensioning disk 18. When the notch 50 protrudes, the free end of one arm 51 engages in it, so that the tensioning disk 18 is secured against rotation. This locking can only be eliminated in that a force is exerted on the other fork arm 54 by pressing it against the action of the spring 55, so that one arm 51 pivots out of the notch 50.

Wie aus Figur 12 ersichtlich, sind an den Aufbiegungen an den Rändern der Längsseiten der beiden Schenkel 5, 6 an den Endbereichen derselben Ausnhemungen 56 vorgesehen, welche im entsprannten Zustand der beiden Schenkel 5, 6 und Durchhängen des daran befindlichen Bezuges ein Eingeben in eine Presse ermöglichen, so daß der Bezug über seine gesamte Länge ausgedrückt werden kann.As can be seen from Figure 12, on the bends on the edges of the long sides of the two legs 5, 6 at the end regions of the same recesses 56 are provided, which in the relaxed state of the two legs 5, 6 and sagging of the cover thereon, an input into a press allow so that the reference can be expressed over its entire length.

Die Ränder der beiden Schenkel 5, 6 sind an ihren Querseiten mit Hochbiegungen 57 ausgerüstet, welche in ihrer Höhe nur geringfügig bemessen sind und vorzugsweise etwa rechtwinklig verlaufen. Diese Hochbiegungen 57 ergeben einen Abrolleffekt beim Spannen der beiden Schenkel 5, 6 auf der Innenseite des Bezuges, so daß dieser Arbeitsvorgang wesentlich erleichtert ist.The edges of the two legs 5, 6 are equipped on their transverse sides with upward bends 57 which are only slightly dimensioned in height and preferably run approximately at right angles. These upward bends 57 result in a rolling effect when the two legs 5, 6 are tensioned on the inside of the cover, so that this process is made considerably easier.

Wie aus Figur 11 und Figur 14 zu ersehen ist, ist in der Unterplatte 9 im Bewegungsbereich eines Rastbolzens 20 eine Mehrkantbohrung 58 vorgesehen. In die Mehrkantbohrung 58 ist ein entsprechen mehrkantig gestalteter Fuß 59 eines Bolzens 60 eingesteckt. Von dem Fuß geht ein Hals 61 in den mehrkantigen Kopf 62 des Bolzens 60 über. Der Hals 61 mündet exzentrisch in den Kopf 62 ein, so daß sich jeweils verschiedene Abstände der Seiten des Kopfes 62 zur Längsachse des Halses 61 ergeben und damit verschiedene Abstände zum Rastbolzen 30. Mindestens der Hals 61 ist aus begrenzt elastischem Material hergestellt, so daß dieser durch den Rastbolzen 20 seitwärts gedrückt werden kann, nach Passieren des Rastbolzens 20 aber wieder seine ursprüngsliche Lage einnimmt. Die Elastizität des Bolzens 61 kann durch einen oder mehrere in seiner Einsteckrichtung verlaufende Einschnitte noch erhöht werden.As can be seen from FIG. 11 and FIG. 14, a polygonal bore 58 is provided in the lower plate 9 in the range of movement of a locking bolt 20. A correspondingly polygonal foot 59 of a bolt 60 is inserted into the polygonal bore 58. A neck 61 passes from the foot into the polygonal head 62 of the bolt 60. The neck 61 opens eccentrically into the head 62, so that there are different distances from the sides of the head 62 to the longitudinal axis of the neck 61 and thus different distances from the locking pin 30. At least the neck 61 is made of limited elastic material so that it can be pressed sideways by the locking pin 20, but after passing through the locking pin 20 it returns to its original position. The elasticity of the bolt 61 can be increased by one or more incisions running in its insertion direction.

Durch diese Ausgestaltung wird erreicht, daß beim Verdrehen der Spannscheibe 18 um ein bestimmtes Winkelmaß der dem eingesteckten Bolzen 60 zugeordnete Rastbolzen 20 unter Beiseitedrückung desselben über diesen hinweggeschwenkt wird. Durch diese Bewegung erfolgt unter gleichzeitigem Spannen der Zugfedern 25 ein stärkeres Auseinanderspreizen der beiden Schenkel 5, 6, ohne daß der Bodenwischer unter der Wirkung der Zugfedern 25 sich verdrehen und seine beiden Schenkel in ihre entspannte Ausgangslage zurückkehren können. Durch den vergrößerten Spreizwinkel ist nunmehr ein leichtes Spannen durch Aufsetzen der Schenkel auf den Boden und anschließendes Weiterdrehen der Spannscheibe in die Arretierungsposition der Rastbolzen 20 möglich.This configuration ensures that when the tensioning disk 18 is rotated by a certain angular dimension, the locking pin 20 assigned to the inserted pin 60 is pivoted over it while pushing it aside. This movement, while simultaneously tensioning the tension springs 25, causes the two legs 5, 6 to spread apart more without the floor wiper twisting under the action of the tension springs 25 and its two legs being able to return to their relaxed starting position. Due to the enlarged spreading angle, easy clamping is now possible by placing the legs on the floor and then turning the clamping disk further into the locking position of the locking bolts 20.
