Die der Oberseite 16 gegenüberliegende Seite ist eine ebene Kehrmittelseite 20 und bildet eine Referenzebene 22.The sweeping means holder 14 has approximately a basic shape of an elongated, a longitudinal direction L defining rectangle, wherein side surfaces 18 are slightly angled with respect to a straight line arranged at right angles to the top 16 and edges and corners of this rectangle are rounded. The approximately rectangular basic shape is wider than it is high. The top side 16 opposite side is a flat Kehrmittelseite 20 and forms a reference plane 22nd

In der Figur 1 ist am Kehrmittelhalter 14 als Kehrmittel 24 ein Borstenbesatz 26 angedeutet, der von der Kehrmittelseite 20 des Kehrmittelhalters 14 absteht. Es handelt sich um den Kopf eines Besens.In the FIG. 1 is on Kehrmittelhalter 14 as a sweeper 24 a bristle stocking 26 indicated, which protrudes from the sweeping means 20 side of the Kehrmittelhalters 14. It is the head of a broom.

Anstelle eines Borstenbesatzes 26 kann das Kehrmittel 24 aber auch durch ein Tuch gebildet sein. Dieses wird mit bekannten Mitteln, wie z.B. Klemmen (nicht gezeigt), an der Oberseite 16 des Kehrmittelhalter 14 angebracht und über die Kehrmittelseite 20 gespannt. Der Teil des Tuchs, welcher an die Kehrmittelseite 20 anliegt wird dabei zum Reinigen benutzt.Instead of a bristle trim 26 but the sweeping means 24 may also be formed by a cloth. This is done by known means, e.g. Clamps (not shown) attached to the top 16 of the sweeper holder 14 and stretched over the Kehrmittelseite 20. The part of the cloth, which rests against the sweeping means 20 is used for cleaning.

Der Gelenkstielhalter 12 weist drei, in den Figuren 2, 3 und 4 gezeigte Einzelteile auf; nämlich ein Stielbefestigungselement 28, ein Arretierorgan 30 und ein Sockelelement 32.The articulated handle holder 12 has three, in the FIGS. 2, 3 and 4 shown items on; namely a handle attachment element 28, a locking member 30 and a base member 32nd

Das Sockelelement 32 ist mittels einer Schraube (nicht gezeigt), welche durch ein mittig angeordnetes Schraubenloch 34 des Sockelelements 32 hindurch in ein Loch 35 des Kehrmittelhalters 14 geschraubt ist, mit dem Kehrmittelhalter 14 fest verbunden. Damit das Sockelelement 32 sich nicht gegenüber dem Kehrmittelhalter 14 verschieben und verdrehen kann, weist das Sockelelement 32 zwei an einer Bodenseite 37 des Sockelelements 32 angeordnete Nocken 35' auf, welche in Ausnehmungen 36 am Kehrmittelhalter 14 eingreifen; es kann nur ein einziger Nocken 35' oder es können mehr als zwei Nocken 35' vorgesehen werden. Das Sockelelement 32 weist zwei halbschalenartige Haltebereiche 38 für Zapfen 40 des Stielbefestigungselements 28 auf. Die Haltebereiche 38 sind bezüglich des Mittelpunkts des Schraubenlochs 34 diametral zueinander angeordnet und definieren eine Achse A, wobei diese Achse A parallel zur Referenzebene 22 und rechtwinklig zur Längsrichtung L verläuft. Die Haltebereiche 38 sind zur Bodenseite 37 hin offen. Sie werden aber bei an den Kehrmittelhalter 14 befestigtem Sockelelement 32 durch den Kehrmittelhalter 14 umfangsseitig bezüglich der Achse A begrenzt.The base member 32 is by means of a screw (not shown) which is screwed through a centrally disposed screw hole 34 of the base member 32 into a hole 35 of the Kehrmittelhalters 14, fixedly connected to the Kehrmittelhalter 14. So that the base member 32 can not move relative to the Kehrmittelhalter 14 and rotate, the base member 32 has two arranged on a bottom side 37 of the base member 32 cam 35 ', which engage in recesses 36 on the Kehrmittelhalter 14; there may be only a single cam 35 'or more than two cams 35' may be provided. The base element 32 has two half-shell-like holding areas 38 for pins 40 of the handle attachment element 28. The holding portions 38 are disposed diametrically opposite each other with respect to the center of the screw hole 34 and define an axis A, which axis A is parallel to the reference plane 22 and runs at right angles to the longitudinal direction L. The holding portions 38 are open to the bottom side 37. However, they are bounded by the Kehrmittelhalter 14 circumferentially with respect to the axis A at fixed to the Kehrmittelhalter 14 base member 32.

Die Haltebereiche 38 weisen in ihren, an die Bodenseite 37 angrenzenden Endbereichen, in Richtung gegeneinander hin vorstehende, Lagerwulste 39 für die Zapfen 40 auf. Diese sind, im montierten Zustand, von den Lagerwulsten 39 in den Haltebereichen 38 gehalten.The holding areas 38 have, in their, adjacent to the bottom side 37 end portions in the direction of mutually projecting, Lagerwulste 39 for the pin 40. These are, in the assembled state, held by the Lagerwulsten 39 in the holding areas 38.

Auf einem Umkreis um das Schraubenloch 34 herum sind zwei Arretierflächen 44 angeordnet, welche diametral zueinander und auf einer Geraden parallel zur Längsrichtung L durch den Mittelpunkt des Umkreises liegen. Die Arretierflächen 44 weisen in Umfangsrichtung des Umkreises eine Ausdehnung auf, die weiter unten beschrieben wird. In Draufsicht auf das Sockelelement 32 grenzen an die Arretierflächen 44 auf dem Umkreis in Gegenuhrzeigersinnrichtung erhöhte Anschläge 46 an. In Uhrzeigersinnrichtung grenzen an die Arretierflächen 44 zwei eine Ausrichtungsvorrichtung 48 bildende Rampen 50 an, welche in Uhrzeigersinnrichtung kontinuierlich von einer Höhe der Arretierflächen 44 bis annähend auf eine Höhe der Bodenseite 37 abfallen. Die Rampen 50 und die Arretierflächen 44 weisen im Querschnitt eine U-förmige Profilierung auf, die dazu dient, weiter unten beschriebene Stützarme 76 zu führen.On a circumference around the screw hole 34 around two locking surfaces 44 are arranged, which are diametrically opposed to each other and on a straight line parallel to the longitudinal direction L through the center of the circumference. The locking surfaces 44 have in the circumferential direction of the circumference of an extent, which will be described below. In plan view of the base member 32 adjacent to the locking surfaces 44 on the circumference in the counterclockwise direction increased stops 46 at. Adjacent to the locking surfaces 44, in the clockwise direction, are two ramps 50 forming an alignment device 48, which continuously descend in a clockwise direction from a height of the locking surfaces 44 to approximately the level of the bottom side 37. The ramps 50 and the locking surfaces 44 have a U-shaped profiling in cross-section, which serves to guide arms 76 described below.

Das Stielbefestigungselement 28 weist in seiner Längsrichtung S einerseits ein Gewindeabschnitt 60 und andererseits ein Gelenkabschnitt 62 auf. Ausser einer weiter unten beschriebenen umlaufenden, radial vorstehenden Wulst 72 liegt das Stielbefestigungselement 28 innerhalb einer, in Längsrichtung S verlaufenden Zylinderfläche (nicht gezeigt). Der Gewindeabschnitt 60 ist radial aussen kegelstumpfartig geformt und weist vier in Längsrichtung S verlaufende, in Umfangsrichtung gleichmässig verteilt angeordnete Verstrebungen 63 auf, die sich jeweils von der Wulst 72 zum Gelenkabschnitt 62 erstrecken. Jede der Verstrebungen 63 ist in einen obere Bereich 63' und einen unteren Bereich 63" unterteilt, wobei der obere Bereich 63' an den Wulst 72 und der untere Bereich 63'' an den Gelenkabschnitt 62 angrenzt. Eine in radialer Richtung aussenliegende Stirnfläche des oberen Bereichs 63' liegt auf der Zylinderfläche. Eine an die Stirnfläche des Bereichs 63' anschliessende Stirnfläche des unteren Bereichs 63" schliesst mit der Zylinderfläche einen kleinen spitzen Winkel ein, wobei der Winkel sich gegen den Gelenkabschnitt 62 öffnet. Im Inneren weist der Gewindeabschnitt 60 ein an einen oberen Endbereich 64 des Stielbefestigungselements 28 angrenzendes Sackloch mit Innengewinde 66 auf. Das Innengewinde 66 ist dazu bestimmt, ein Aussengewinde eines Stiels aufzunehmen.The handle attachment element 28 has in its longitudinal direction S on the one hand a threaded portion 60 and on the other hand a hinge portion 62. Apart from a circumferential, radially projecting bead 72 described below is the handle attachment element 28 within a longitudinal direction S extending cylindrical surface (not shown). The threaded portion 60 is frusto-conically shaped radially outward and has four extending in the longitudinal direction S, circumferentially uniformly distributed struts 63, each extending from the bead 72 to the hinge portion 62. Each of the struts 63 is subdivided into an upper region 63 'and a lower region 63 ", wherein the upper region 63' adjoins the bead 72 and the lower region 63" adjoins the joint section 62. A radially outwardly facing end face of the upper An end face of the lower region 63 "adjoining the end face of the region 63 'encloses a small acute angle with the cylindrical surface, the angle opening against the hinge section 62. In the interior, the threaded portion 60 has an internal thread 66 blind hole adjoining an upper end region 64 of the handle fastening element 28. The internal thread 66 is intended to receive an external thread of a stem.

Der Gelenkabschnitt 62 ist durch zwei sich in Längsrichtung S vom Gewindeabschnitt 60 weg erstreckende Arme 68 ausgebildet. Bezüglich einer Längsachse des Zylinders liegen sich die Arme 68 gegenüber. Jeder Arm 68 weist eine Längsmittelachse parallel zur Längsrichtung S auf. Die Längsmittelachsen der Arme 68 definieren eine Längsmittelebene (nicht gezeigt). Bezüglich dieser Längsmittelebene ist jeder Arm 68 symmetrisch ausgebildet. Die in radialer Richtung aussenliegenden Flächen der Arme 68 liegen auf der Zylinderfläche. Bezüglich der Umfangsrichtung des Zylinders verjüngt sich jeder Arm 68 in Richtung seines freien Endabschnitts 70 und ist am freien Ende abgerundet. In den freien Endabschnitten 70 jedes Armes 68 sind die Zapfen 40 jeweils innenseitig angeformt und greifen im montierten Zustand drehbar in den Haltebereich 38 des Sockelelements 32 ein.The hinge portion 62 is formed by two arms 68 extending away from the threaded portion 60 in the longitudinal direction S. With respect to a longitudinal axis of the cylinder, the arms 68 are opposite. Each arm 68 has a longitudinal central axis parallel to the longitudinal direction S. The longitudinal center axes of the arms 68 define a longitudinal center plane (not shown). With respect to this longitudinal median plane, each arm 68 is formed symmetrically. The radially outward surfaces of the arms 68 lie on the cylindrical surface. With respect to the circumferential direction of the cylinder, each arm 68 tapers in the direction of its free end portion 70 and is on rounded off at the free end. In the free end portions 70 of each arm 68, the pins 40 are each formed on the inside and engage rotatably in the mounted state in the holding portion 38 of the base member 32 a.

Im oberen Endbereich 64 weist der Gewindeabschnitt 60 aussenseitig die umlaufende Wulst 72 auf, welche einen Anschlag 74 für das Arretierorgan 30 bildet. Ein schulterartiger Anschlag 75 ist von dem an der Wulst 72 gelegenen Anschlag 74 in Richtung des Gelenkabschnitts 68 beabstandet und diesem zugewandt. Der an der Wulst 72 gelegene Anschlag 74 und der schulterartige Anschlag 75 sind dazu bestimmt, das weiter unten beschriebenes Arretierorgan 30 in Längsrichtung S nahezu unverschiebbar zu halten.In the upper end region 64, the threaded portion 60 on the outside of the circumferential bead 72, which forms a stop 74 for the locking member 30. A shoulder-like stopper 75 is spaced from the abutment 74 located on the bead 72 in the direction of the hinge portion 68 and facing it. The stop 74 located on the bead 72 and the shoulder-like stop 75 are intended to hold the locking member 30 described below in the longitudinal direction S virtually immovable.

Das Arretierorgan 30 ist drehbar bezüglich der Längsrichtung S am Stielbefestigungselement 28 angeordnet und weist einen Haltebereich 77 und einen Stützbereich 77' auf. Der Haltebereich 77 umfasst im montierten Zustand den Gewindeabschnitt 60 des Stielbefestigungselements 28 mit Ausnahme der Wulst 72 hülsenartig und grenzt mit einer inneren Seite an die Zylinderfläche an. Der Haltebereich 77 ist derart ausgeformt, dass er mit einer Anschlagsfläche 80 bildenden Stirnfläche 79 an den Anschlag 74 der Wulst 72 des Stielbefestigungselements 28 ansteht. Auf der Innenseite weist der Haltebereich 77 des Arretierorgans 30 nasenartige Gegenschultern (nicht gezeigt) auf, welche einen Gegenanschlag an den schulterartigen Anschlag 75 des Stielbefestigungselements 28 bilden und derart angeordnet sind, dass das Arretierorgan 30 einerseits mit der Anschlagsfläche 80 am Wulst 72 gelegenen Anschlag 74 des Stielbefestigungselements 28 und andererseits mit den nasenartigen Gegenschultern am schulterartigen Anschlag 75 des Stielbefestigungselements 28 ansteht. Dadurch ist das Arretierorgan 30 in Längsrichtung S fest am Stielbefestigungselement 28 gehalten.The locking member 30 is rotatably arranged with respect to the longitudinal direction S on the handle attachment member 28 and has a holding portion 77 and a support portion 77 'on. The holding portion 77 in the mounted state, the threaded portion 60 of the handle attachment member 28 except for the bead 72 sleeve-like and adjacent to an inner side of the cylindrical surface. The holding region 77 is formed in such a way that it rests against the stop 74 of the bead 72 of the handle attachment element 28 with an end face 79 forming a stop surface 80. On the inside, the holding portion 77 of the locking member 30 nose-like counter-shoulders (not shown), which form a counter-attack on the shoulder-like stop 75 of the handle attachment member 28 and are arranged such that the locking member 30 on the one hand with the stop surface 80 located on the bead 72 stop 74th of the handle attachment member 28 and on the other hand with the nose-like counter shoulders on the shoulder-like stop 75 of the handle attachment member 28 is present. As a result, the locking member 30 is held firmly in the longitudinal direction S on the handle attachment member 28.

Der Stützbereich 77' des Arretierorgans 30 ist durch zwei sich in Längsrichtung S vom Haltebereich 77 weg erstreckende Stützarme 76 ausgebildet. Bezüglich einer Längsachse des Zylinders liegen sich die Stützarme 76 gegenüber. Jeder Stützarm 76 weist eine Längsmittelachse parallel zur Längsrichtung S auf. Die Längsmittelachsen definieren eine Längsmittelebene (nicht gezeigt). Bezüglich dieser Längsmittelebene ist jeder Stützarm 76 symmetrisch ausgebildet. Die in radialer Richtung innenliegenden Flächen der Stützarme 76 liegen an die Zylinderfläche an. Bezüglich der Umfangsrichtung des Zylinders verjüngt sich jeder Stützarm 76 in Richtung seines freien Endabschnitts und weist eine rechtwinklig zu seiner Längsmittelachse stehende Stützfläche 78 auf. Die Stützflächen 78 weisen die gleiche Grösse auf wie die Arretierflächen 44 des Sockelelements 32 und sind passend zu der Profilierung der Arretierflächen 44 des Sockelelements 32 ausgeformt. Auf einer Aussenseite weist das Arretierorgan 30 in Längsrichtung S verlaufende Rillen 81 auf, welche eine bessere Handhabung des Arretierorgans 30 ermöglichen. Die Stützarme 76 sind ähnlich zu den Armen 68 des Stielbefestigungselements 28 geformt, sind jedoch kürzer.The support region 77 'of the locking member 30 is formed by two extending in the longitudinal direction S from the support portion 77 away support arms 76. With respect to a longitudinal axis of the cylinder, the support arms 76 are opposite. Each support arm 76 has a longitudinal central axis parallel to the longitudinal direction S. The longitudinal center axes define a longitudinal center plane (not shown). With respect to this longitudinal center plane, each support arm 76 is formed symmetrically. The radially inward surfaces of the support arms 76 abut against the cylinder surface. With respect to the circumferential direction of the cylinder, each support arm 76 tapers in the direction of its free end portion and has a support surface 78 perpendicular to its longitudinal central axis. The support surfaces 78 have the same size as the locking surfaces 44 of the base member 32 and are formed to match the profiling of the locking surfaces 44 of the base member 32. On an outer side, the locking member 30 extending in the longitudinal direction S grooves 81, which allow better handling of the locking member 30. The support arms 76 are shaped similar to the arms 68 of the handle attachment member 28, but are shorter.

Eine Freigabestellung des Arretierorgans 30 ist dadurch definiert, dass in der Längsmittelebene der Stützarme 76 des Arretierorgans 30 die Achse A des Sockelelements 32 beziehungsweise der Zapfen 40 des Stielbefestigungselements verläuft. Die Stützarme 76 Stielbefestigungselements verläuft. Die Stützarme 76 liegen somit in radialer Richtung an die Arme 68 des Stielbefestigungselements 28 an. Eine Arretierstellung des Arretierorgans 30 ist dadurch definiert, dass das Arretierorgan 30 um 90 Grad um die Längsrichtung S des Stielbefestigungselements 28 herum gedreht ist. In Arretierstellung verläuft die Längsmittelebene der Stützarme 76 rechtwinklig zur Achse A des Sockelelements beziehungsweise der Zapfen 40 des Stielbefestigungselements 28. In Arretierstellung sind die Stützarme 76 des Arretierorgans 30 auf den Arretierflächen 44 des Sockelelements 32 abgestützt.A release position of the locking member 30 is defined by the fact that in the longitudinal center plane of the support arms 76 of the locking member 30 extends the axis A of the base member 32 and the pin 40 of the handle attachment member. The support arms 76 Handle attachment element runs. The support arms 76 are thus in the radial direction of the arms 68 of the handle attachment member 28 at. A locking position of the locking member 30 is defined by that the locking member 30 is rotated by 90 degrees about the longitudinal direction S of the handle attachment member 28 around. In the locking position, the longitudinal center plane of the support arms 76 extends at right angles to the axis A of the base element or the pin 40 of the handle attachment member 28. In the locking position, the support arms 76 of the locking member 30 are supported on the locking surfaces 44 of the base member 32.

Das Arretierorgan 30 weist angrenzend an die Anschlagsfläche 80 und innenseitig zwei Drehbegrenzungsbereiche 82 mit je zwei Rastnocken 84 auf. Die Drehbegrenzungsbereiche 82 sind durch Ausnehmungen in radialer Richtung gebildet und erstrecken sich in Umfangsrichtung über einen Winkelbereich, der etwas grösser als 90 Grad ist. Die zwei Drehbegrenzungsbereiche 82 liegen sich diametral gegenüber. Die Drehbegrenzungsbereiche 82 wirken mit zwei am Stielbefestigungselement 28 angeordneten nockenartigen Drehbegrenzungselementen 86 zusammen, welche in die Drehbegrenzungsbereiche 82 eingreifen. Die Drehbegrenzungsbereiche 82 sind derart angeordnet und ausgebildet, dass das Arretierorgan 30 um 90 Grad von der Freigabestellung in die Arretierstellung und zurück drehbar ist. Durch die Rastnocken 84 ist ein unbeabsichtigtes Drehen des Arretierorgans 30 aus der Freigabestellung in die Arretierstellung beziehungsweise aus der Arretierstellung in die Freigabestellung verhindert. In Arretierstellung wie in Freigabestellung grenzt an jedes der Drehbegrenzungselemente 86 einerseits eine in Umfangsrichtung liegende Endfläche 88 des Drehbegrenzungsbereichs 82 und andererseits einer der Rastnocken 84 an. Jeweils einer der Rastnocken 84 bildet zusammen mit dem entsprechenden Drehbegrenzungselement 86 und der entsprechenden Endfläche 88 eine Einrastschnappverbindung 84, 86, 88.The locking member 30 has adjacent to the abutment surface 80 and on the inside two Drehbegrenzungsbereiche 82, each with two locking cams 84. The rotation limiting areas 82 are formed by recesses in the radial direction and extend in the circumferential direction over an angular range which is slightly greater than 90 degrees. The two rotation limiting areas 82 are diametrically opposed. The rotation limiting regions 82 cooperate with two cam-like rotation limiting elements 86 arranged on the handle fastening element 28, which engage in the rotation limiting regions 82. The rotation limiting portions 82 are arranged and formed such that the locking member 30 is rotatable 90 degrees from the release position to the lock position and back. By the locking cams 84 inadvertent rotation of the locking member 30 is prevented from the release position into the locking position or from the locking position to the release position. In the locking position as in the release position adjacent to each of the rotation limiting elements 86 on the one hand a circumferential end surface 88 of the rotation limiting portion 82 and on the other hand, one of the locking cams 84 at. In each case one of the latching cams 84, together with the corresponding rotation limiting element 86 and the corresponding end face 88, forms a latching snap connection 84, 86, 88.

Der Gelenkstielhalter 12 bestehend aus dem Stielbefestigungselement 28, dem Arretierorgan 30 und dem Sockelelement 32 wird bevorzugt in einem Spritzgussverfahren aus einem Kunststoff hergestellt. Der Kehrmittelhalter kann ebenfalls aus einem Kunststoff hergestellt sein aber auch aus einem anderen Material wie beispielsweise Holz.The articulated handle holder 12 consisting of the handle attachment element 28, the locking member 30 and the base member 32 is preferably made of a plastic in an injection molding process. The Kehrmittelhalter may also be made of a plastic but also of a different material such as wood.

Die Funktionsweise des Gelenkstielhalters 12 ist wie folgt. In Freigabestellung des Arretierorgans 30 ist der Gelenkstielhalter 12 in einer Ebene rechtwinklig zur Referenzebene 22 und in Längsrichtung L verlaufend beweglich. Falls diese Beweglichkeit nicht gewünscht ist, kann das Stielbefestigungselement 28 mit dem daran angeordneten Arretierorgan 30 in eine Stellung gebracht werden, in welcher die Längsrichtung S zumindest einigermassen rechtwinklig zur Längsrichtung L verläuft. In dieser Stellung wird das Arretierorgan 30 um 90 Grad von der Freigabestellung in die Arretierstellung gedreht. Je nach Ausgangsstellung der Längsrichtung L des Kehrmittelhalters 14 zur Längsrichtung S des Stielbefestigungselements 28 gelangen die Stützarme 76 an einem anderen Punkt in Berührung mit den Rampen 50 des Sockelelements 32, wodurch beim weiterdrehen des Arretierorgans 30 das Sockelelement 32 und damit auch die Längsrichtung L des Kehrmittelhalters 14 in eine bezüglich der Längsrichtung S des Stielbefestigungselements 28 der Rampen 50 und der Arretierflächen 44 des Sockelelements 32 einerseits und der Stützflächen 78 der Stützarme 76 andererseits werden die Stützarme 76 geführt. In Arretierstellung stützen sich die Stützarme 76 auf den Arretierflächen 44 ab und sind mit den Anschlägen 46 zumindest annähernd in Berührung. Die Anschläge 46 verhindern einseitig eine Bewegung der Stützarme 76 über die Arretierflächen 44 hinaus. Falls die ursprüngliche Beweglichkeit des Gelenkstielhalters 12 wieder benötigt ist, wird das Arretierorgan 30 von der Arretierstellung in die Freigabestellung zurück gedreht.The operation of the handle holder 12 is as follows. In the release position of the locking member 30 of the handle holder 12 is in a plane perpendicular to the reference plane 22 and in the longitudinal direction L extending movable. If this mobility is not desired, the handle attachment member 28 may be brought with the locking member 30 disposed thereon in a position in which the longitudinal direction S at least to some extent perpendicular to the longitudinal direction L. In this position, the locking member 30 is rotated by 90 degrees from the release position to the locking position. Depending on the initial position of the longitudinal direction L of the Kehrmittelhalters 14 to the longitudinal direction S of the handle attachment member 28 reach the support arms 76 at another point in contact with the ramps 50 of the base member 32, whereby upon further rotation of the locking member 30, the base member 32 and thus also the longitudinal direction L of Kehrmittelhalters 14 in a respect to the longitudinal direction S of the handle attachment member 28th the ramps 50 and the locking surfaces 44 of the base member 32 on the one hand and the support surfaces 78 of the support arms 76 on the other hand, the support arms 76 are guided. In the locking position, the support arms 76 are supported on the locking surfaces 44 and are at least approximately in contact with the stops 46. The stops 46 prevent one-sided movement of the support arms 76 beyond the locking surfaces 44 addition. If the original mobility of the handle holder 12 is needed again, the locking member 30 is rotated back from the locking position to the release position.

Die Montage erfolgt wie folgt. Zunächst wird das Stielbefestigungselement 28 mit den Armen 68 voraus von der Seite der Anschlagsfläche 80 des Arretierorgans 30 her in das Arretierorgan 30 eingesetzt und die Arme 68 werden in Deckung mit den Stützarmen 76 gebracht. Dabei kommen die Drehbegrenzungselemente 86 mit den Drehbegrenzungsbereichen 82 in Eingriff. Beim Einsetzten des Stielbefestigungselements 28 in das Arretierorgan 30 wird das Arretierorgan 30 durch die nasenartigen Gegenschultern elastisch aufgeweitet, und sobald die nasenartigen Gegenschultern den schulterartigen Anschlag 75 passiert haben, formt sich das Arretierorgan in seine ursprüngliche Form zurück. Folglich ist das Arretierorgan 30 in Längsrichtung S fest am Stielbefestigungselement 28 gehalten.The assembly takes place as follows. First, the handle attachment member 28 is inserted with the arms 68 in advance from the side of the abutment surface 80 of the locking member 30 ago in the locking member 30 and the arms 68 are brought into coincidence with the support arms 76. In this case, the rotation limiting elements 86 engage with the rotation limiting areas 82. When inserting the handle attachment member 28 in the locking member 30, the locking member 30 is elastically expanded by the nose-like counter-shoulders, and as soon as the nose-like counter-shoulders have passed the shoulder-like stop 75, the locking member is formed back to its original shape. Consequently, the locking member 30 is held in the longitudinal direction S fixed to the handle attachment member 28.

In einem darauf folgenden Schritt werden die Zapfen 40 des Stielbefestigungselements 28 in die Haltebereiche 38 das Sockelelement 32 gelegt - dabei wird durch elastisches Verdrängen der Widerstand der Lagerwulste 39 überwunden, welche bei vollständig eingesetzten Zapfen 40 diese am Herausfallen aus den Haltebereichen 38 während der Montage hindern - und das Sockelelement 32 gegenüber dem Stielbefestigungselement 28 derart ausgereichtet, dass die Nocken 35' des Sockelelements 32 der Oberseite 16 des Kehrmittelhalters 14 zugewandt sind. Die Nocken 35' werden darauf in die Ausnehmungen 36 des Kehrmittelhalters 14 gesetzt und das Sockelelement 32 wird mittels einer Schraube, welche durch das Schraubenloch 34 geführt und in den Kehrmittelhalter 14 geschraubt wird, mit diesem fest verbunden.In a subsequent step, the pins 40 of the handle attachment member 28 in the holding portions 38, the base element 32 placed - this is overcome by elastic displacement of the resistance of Lagerwulste 39, which at fully inserted pin 40 from falling out of the holding portions 38 during assembly prevent - and the base member 32 relative to the handle attachment member 28 designed such that the cams 35 'of the base member 32 of the top 16 of the Kehrmittelhalters 14 are facing. The cams 35 'are placed thereon in the recesses 36 of the Kehrmittelhalters 14 and the base member 32 is by means of a screw which is guided through the screw hole 34 and screwed into the Kehrmittelhalter 14, fixedly connected thereto.

Bei einer weiteren Ausbildung des Kehrgerätekopfs weist der Gelenkstielhalter nur für die Arretierstellung oder für die Freigabestellung eine Einrastschnappverbindung auf. Eine Ausbildung des Kehrgerätekopfs ohne eine Einrastschnappverbindung ist ebenfalls möglich.In a further embodiment of the sweeping device head, the articulated handle holder has a latching snap connection only for the locking position or for the release position. A design of the sweeping head without a snap-in connection is also possible.

Bei einer weiteren Ausbildung des Kehrgerätekopfs ist das Sockelelement integral mit dem Kehrmittelhalter geformt. Anstelle der zwei Zapfen am Stielbefestigungselement kann beispielsweise ein Stift verwendet werden.In a further embodiment of the sweeping device head, the base element is integrally molded with the Kehrmittelhalter. Instead of the two pins on the handle attachment element, for example, a pin can be used.

Ein Reinigungsgerät mit einem der oben beschriebenen Kehrgeräteköpfe weist einen am Stielbefestigungselement des Gelenkstielhalters angebrachten Stiel auf. Der Stiel weist für das in der Zeichnung gezeigte Ausführungsbeispiel des Kehrgerätekopfs 10 ein zum Innengewinde des Stielbefestigungselement 28 passendes Aussengewinde auf. Der Stiel wird zum Reinigen in das Stielbefestigungselement 28 eingeschraubt. Für die Lagerung des Reinigungsgerätes kann der Stiel beispielsweise aus Platzgründen vom Kehrgerätekopf entfernt werden.A cleaning device with one of the sweeping heads described above has a handle attached to the handle attachment element of the handle holder. The stem has for the embodiment of the sweeping head 10 shown in the drawing on an internal thread of the handle attachment member 28 matching external thread.
