Description

Die Erfindung betrifft eine lösbare Stielbefestigung für Besen oder Schrubber gemäß dem Oberbegriff des Anspruches 1.The invention relates to a detachable handle attachment for brooms or scrubbers according to the preamble of claim 1.

Eine derartige lösbare Stielbefestigung ist aus dem DE-U 77 34 201 bekannt. Als Spannelement dient hierbei ein Spannschieber, der auf am Stiel befestigten Schenkeln des Führungs- und Halteteils verschiebbar angeordnet ist. Die Federbügel sind auf abgekröpften Stegen des Führungs- und Halteteils schwenkbar gelagert, wobei die den Klemmbügeln entgegengesetzten Abschnitte dieser Federbügel von dem Spannschieber übergriffen werden, so daß beim Verschieben des Spannschieber in eine Schließstellung die Federbügel derart verschwenkt werden, daß sie in eine gegenüber den Klemmlöchern im Borstenkörper verspannte Stellung kommen. Zum Lösen dieser Klemmbefestigung wird der Spannschieber zu den das Schwenklager für die Federbügel bildenden Stegen verschoben, wodurch die Klemmbügel entspannt werden. Diese bekannte Lösung stellt zwar eine zuverlässige Befestigung zwischen Borstenkörper und Halte- und Führungskörper her, ist aber konstruktiv verhältnismäßig aufwendig und insofern störanfällig, als der Spannschieber keine ausreichend gute Führung auf den Schenkeln des Führungs- und Halteteils hat.Such a releasable handle attachment is known from DE-U 77 34 201. A tensioning slide serves as the tensioning element, which is slidably arranged on legs of the guide and holding part fastened to the handle. The spring clips are pivotally mounted on bent webs of the guide and holding part, the sections of these spring clips opposite the clamping clips being overlapped by the tensioning slide, so that when the tensioning slide is moved into a closed position, the spring clips are pivoted in such a way that they move into a position opposite the clamping holes come tense position in the bristle body. To release this clamp fastening, the tensioning slide is moved to the webs forming the pivot bearing for the spring clips, whereby the clamping clips are relaxed. Although this known solution produces a reliable attachment between the bristle body and the holding and guiding body, it is structurally relatively complex and susceptible to failure insofar as the cocking slide does not have sufficiently good guidance on the legs of the guiding and holding part.

Weiterhin ist aus dem DE-U 78 17 630 eine lösbare Stielbefestigung für Besen oder Schrubber bekannt, bei der ebenfalls von einem Führungs- und Halteteil Befestigungsschenkel vorspringen, die in entsprechende Haltelöcher eines Borstenkörpers eingreifen. Es sind weiterhin vorgespannte Federbügel vorgesehen, deren als Klemmbügel dienende Enden in entsprechende Klemmlöcher im Borstenkörper eingreifen. Durch weiteres Verspannen mittels einer Druckplatte können diese Klemmbügel in eine Stellung gebracht werden, in der ein Abziehen des Führungs- und Halteteils vom Borstenkörper möglich ist. Der Nachteil dieser Ausgestaltung liegt darin, daß die Vorspannung der Federbügel nicht ausreicht, den Borstenkörper zuverlässig am Führungs- und Halteteil in der relativ entspannten Lage der Klemmbügel zu halten. Würde man zur Beseitigung dieses Nachteils die Vorspannkraft entsprechend erhöhen, dann würde wiederum die erforderliche Lösekraft jeden vernünftigen Rahmen überschreiten.Furthermore, from DE-U 78 17 630 a releasable handle attachment for brooms or scrubbers is known, in which fastening legs also protrude from a guide and holding part, which engage in corresponding holding holes in a bristle body. Preloaded spring clips are also provided, the ends of which serve as clamping clips engage in corresponding clamping holes in the bristle body. By further tensioning by means of a pressure plate, these clamping brackets can be brought into a position in which it is possible for the guide and holding part to be pulled off the bristle body. The disadvantage of this embodiment is that the pretension of the spring clip is not sufficient to reliably hold the bristle body on the guide and holding part in the relatively relaxed position of the clamping clip. If the pre-tensioning force were to be increased accordingly to eliminate this disadvantage, then the required loosening force would again exceed any reasonable framework.

Aus der DE-A 2 651 259 ist eine lösbare Stielbefestigung für Besen oder Schrubber mit einem mit einem Stiel verbundenen Halteteil bekannt. Dieses Halteteil weist als Klemmbügel dienende Haltearme auf, die in Löcher eines Borstenkörpers eingreifen. Die Haltearme sind in der durch sie aufgespannten Ebene spreizbar bzw. aufeinander zu bewegbar, wodurch eine Verspannung in den Löchern des Borstenkörpers erfolgt. Zur Verspannung der haltearme ist ein Schwenkhebel vorgesehen, mittels dessen die Haltearme entweder aufeinander zubewegt oder auseinandergedrückt werden können. Eine ausreichend sichere und einfach zu bedienende Befestigung zwischen Borstenkörper einerseits und Stiel andererseits ist hierdurch nicht gewährleistet.From DE-A 2 651 259 a releasable handle attachment for brooms or scrubbers with a holding part connected to a handle is known. This holding part has holding arms which serve as a clamping bracket and which engage in holes in a bristle body. The holding arms can be spread or moved towards one another in the plane spanned by them, as a result of which bracing takes place in the holes in the bristle body. A swivel lever is provided for bracing the holding arms, by means of which the holding arms can either be moved towards one another or pressed apart. A sufficiently secure and easy-to-use attachment between the bristle body on the one hand and the handle on the other hand is not guaranteed by this.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Stielbefestigung der gattungsgemäßen Art zu schaffen, die bei geringen Betätigungskräften eine zuverlässige Halterung zwischen Stiel und Borstenkörper gewährleistet.The invention is therefore based on the object of providing a handle attachment of the generic type which ensures reliable holding between the handle and the bristle body at low actuation forces.

Diese Aufgabe wird bei einer lösbaren Stielbefestigung gemäß dem Oberbegriff des Anspruches 1 durch die Merkmale des Kennzeichnungsteils des Anspruches 1 gelöst. Durch ein Verschwenken des Schwenkhebels werden die Klemmbügel mit dem Borstenkörper unter elastischer Verformung der Klemmbügel in eine verspannte Lage fest verklemmt bzw. verkrallt, während durch ein Verschwenken des Schwenkhebels in eine andere Endlage die Federbügel soweit entlastet werden, daß die Klemmbügel frei und unverspannt in den Klemmlöchern des Borstenkörpers sich befinden. Wird der Besen oder Schrubber hierbei mit dem Stiel nach unten gehalten, so fällt der Borstenkörper in dieser entspannten Stellung von allein vom Führungs- in Haltekörper ab. Es ist also einerseits eine absolut zuverlässige Halterung zwischen Borstenkörper und Führungs- und Halteteil einerseits und eine äußerst leichte Lösung dieser Verbindung gewährleistet. Hierdurch ist also ein sogenannter Schnellwechsel-Stiel geschaffen worden.This object is achieved in a detachable handle attachment according to the preamble of claim 1 by the features of the characterizing part of claim 1. By pivoting the pivot lever, the clamping bracket with the bristle body with elastic deformation of the clamping bracket in a clamped position is firmly clamped or clawed, while by pivoting the pivot lever into another end position, the spring clips are relieved so far that the clamping bracket is free and untensioned in the There are clamping holes in the bristle body. If the broom or scrubber is held with the handle pointing downwards, the bristle body in this relaxed position automatically falls off the guide body into the holding body. On the one hand, an absolutely reliable mounting between the bristle body and the guide and holding part, on the one hand, and an extremely easy solution of this connection is guaranteed. In this way, a so-called quick-change handle has been created.

Weitere Vorteile und Merkmale ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels anhand der Zeichnung. In der Zeichnung zeigt

  • Figur 1 eine perspektivische Darstellung einer Stielbefestigung gemäß der Erfindung in Explosionsdarstellung,
  • Figur 2 einen Schnitt durch die Stielbefestigung etwa gemäß der Schnittlinie 11-11 in Fig. 1 in entspannter Stellung und,
  • Figur 3 eine Darstellung entsprechend Fig. 2 in verspannter Stellung.
Further advantages and features emerge from the subclaims and the following description of an exemplary embodiment with reference to the drawing. In the drawing shows
  • FIG. 1 shows an exploded perspective view of a handle attachment according to the invention,
  • FIG. 2 shows a section through the handle attachment approximately according to section line 11-11 in FIG. 1 in a relaxed position, and
  • 3 shows a representation corresponding to FIG. 2 in the tensioned position.

Am freien Ende eines Stiels 1 für einen Besen oder Schrubber ist ein Führungs- und Halteteil 2 befestigt, das im wesentlichen etwa die Form eines gleichschenkligen, leicht stumpfwinkligen Dreiecks hat. An den beiden dem Stiel 1 abgewandten Ecken sind zwei parallel zueinander vorspringende Befestigungsschenkel3 ausgebildet. Diese frei vorstehenden Befestigungsschenkel 3 werden in entsprechende Haltelöcher4 eines an seiner Unterseite mit Borstenbüscheln 5 besetzten Borstenkörpers 6 eines Besens oder Schrubbers von oben eingeführt. Diese beiden Haltelöcher 4 haben den gleichen mittleren Abstand voneinander wie die beiden Befestigungsschenkel 3 ; ihr Durchmesser ist etwas größer als der Durchmesser der Befestigungsschenkel3, so daß letztere leichtgängig eingeführt werden können. Wie insbesondere aus den Fig.2 und 3 hervorgeht, sind die beiden Befestigungsschenkel3 in einer Ebene angeordnet, gegenüber der der Stiel 1 um 30 bis 40° geneigt ist, so daß bei einer normalen Auflage des Borstenkörpers 6 auf dem Boden, bei der die Befestigungsschenkei 3 etwa senkrecht angeordnet sind, der Stiel 1 in einer für die Bedienungsperson bequemen Schräglage ist.At the free end of a handle 1 for a broom or scrubber, a guide and holding part 2 is attached, which has approximately the shape of an isosceles, slightly obtuse triangle. At the two corners facing away from the handle 1, two fastening legs 3 projecting parallel to one another are formed. These freely projecting fastening legs 3 are inserted from above into corresponding holding holes 4 of a bristle body 6 of a broom or scrubber which is covered with bristle tufts 5 on its underside. These two holding holes 4 have the same average distance from each other as the two fastening legs 3; their diameter is slightly larger than the diameter of the fastening legs 3, so that the latter runs smoothly can be introduced. As can be seen in particular from FIGS. 2 and 3, the two fastening legs 3 are arranged in a plane with respect to which the handle 1 is inclined by 30 to 40 °, so that with a normal support of the bristle body 6 on the floor, in which the fastening leg 3 are arranged approximately vertically, the handle 1 is in an inclined position which is comfortable for the operator.

An der Unterseite des Führungs- und Halteteils 2 sind zwei Federbügel 7 in der Nähe des zugeordneten Endes des Stieles 1 in Lagern 8 fest eingespannt. Die noch über die Lager 8 zum Stiel 1 hin überstehenden Enden 9 der Federbügel7 liegen gegen die entsprechende Unterseite des Führungs- und Halteteils 2 an. Wie aus der Zeichnung ersichtlich ist, können die Federbügel 7 hier mit ihren Enden 9 verbunden sein, d.h. beide Federbügel 7 können aus einem Federdraht gebogen sein.On the underside of the guide and holding part 2, two spring clips 7 are firmly clamped in bearings 8 in the vicinity of the associated end of the stem 1. The ends 9 of the spring clip 7 which still protrude beyond the bearing 8 towards the handle 1 lie against the corresponding underside of the guide and holding part 2. As can be seen from the drawing, the spring clips 7 can be connected here with their ends 9, i.e. both spring clips 7 can be bent from a spring wire.

Die über den dem Stiel 1 abgewandten unteren Rand 10 vorstehenden Enden der Federbügel 7 ist alks Klemmbügel 11 mit einem schräg nach hinten und unten abgewinkelten, als Halte-haken 12 dienenden freien Ende ausgebildet. Diese Klemmbügel 11 mit Haltehaken 12 werden in Klemmlöcher 13 im Borstenkörper 6 eingeführt, die in der Ebene der haltelöcher4 angeordnet sind, und deren mittlerer Abstand dem Abstand der Klemmbügel 11 voneinander enspricht. Der Durchmesser dieser Klemmlöcher 13 ist so groß daß die Klemmbügelll in der in Fig. 2 dargestellten entspannten Lage trotz ihrer nach hinten und unten abgewinkelten Haltehaken 12 in die Klemmlöcher13 frei eingeführt werden können, wenn gleichzeitig die Befestigungsschenkel 3 in die Haltelöcher4 eingeführt werden. Gleiches gilt für ein Abziehen des Führungs- und Halteteils vom Borstenkörper, der in der in Fig. dargestellten Stellung vom Führungs- und Halteteil 2 abfällt. Die zwischen dem Lager und dem Klemmbügel 11 jeweils befindlichen Abschnitte der Federbügel7 dienen als Spannbügel 14. Zwischen Ihnen und der zugeordneten Unterseite des Führungs- und Halteteils 2 sind jeweils ein als Stellglied 15 dienender Zapfen mit unrundem Querschnitt angeordnet. Diese Stellglieder haben also die Funktion von Exzentern. Beide Stellglieder 15 fluchten etwa miteinander. An diesen exzenterartigen Stellgliedern sind die Schenkel 16 eines Schwenkhebels 17 befestigt, die sich durch angepaßte, parallel zueinander und parallel zum Stiel 1 Verlaufende Schlitze 18 im Führungs- und halteteil zu dessen Oberseite hin erstrecken. An ihrem gemeinsamen Ende ist ein gemeinsamer Bedienungsknopf 19 angebracht.The ends of the spring clip 7 projecting beyond the lower edge 10 facing away from the stem 1 is formed as a clamping clip 11 with an angled backward and downward free end serving as a holding hook 12. These clamps 11 with holding hooks 12 are inserted into clamping holes 13 in the bristle body 6, which are arranged in the plane of the holding holes 4, and the average distance between which corresponds to the distance between the clamps 11. The diameter of these clamping holes 13 is so large that the clamping brackets in the relaxed position shown in FIG. 2 can be freely inserted into the clamping holes 13 in spite of their holding hooks 12 angled backwards and downwards, if the fastening legs 3 are simultaneously inserted into the holding holes 4. The same applies to the pulling off of the guide and holding part from the bristle body, which drops off from the guide and holding part 2 in the position shown in FIG. The sections of the spring bracket 7 located between the bearing and the clamping bracket 11 each serve as a tensioning bracket 14. Between them and the associated underside of the guide and holding part 2, a pin serving as an actuator 15 with a non-circular cross section is arranged. These actuators therefore have the function of eccentrics. Both actuators 15 are approximately aligned. On these eccentric actuators, the legs 16 of a pivot lever 17 are fastened, which extend through adapted slots 18 in the guide and holding part, parallel to one another and parallel to the handle 1, towards the top thereof. A common control button 19 is attached to their common end.

In der in Fig. dargestellten Lage sind die Stellglieder 15 so verschwenkt, daß ihr Bereich geringsten Durchmessers zwischen den Spannbügeln 14 und der als Auflager dienenden Unterseite des Führungs- und Halteteils ist. Die Federbügel 7 befinden sich hierbei in ihrer weitgehend entspannten Stellung, in der die Klemmbügel 11 samt Haltehaken 12 vollständig in dem von den beiden Befestigungsschenkeln 3 überspannten Raum sich befinden. Eine geringfügige Vorspannung haben die Federbügel 7 auch in dieser Stellung, damit zum einen die Klemmbügel 11 eine definierte Lage einnehmen und damit der Schwenkhebel 17 ausreichend gehaltert wird.In the position shown in Fig. The actuators 15 are pivoted so that their smallest diameter area between the clamping bracket 14 and the underside of the guide and holding part serving as a support. The spring clips 7 are in their largely relaxed position, in which the clamping clips 11 together with the retaining hooks 12 are located completely in the space spanned by the two mounting legs 3. The spring clips 7 also have a slight pretension in this position, so that the clamping clips 11 assume a defined position on the one hand and so that the pivot lever 17 is held sufficiently.

In der in Fig. 3 dargestellten Stellung, in der das mit dem Bedienungsknopf 19 versehene Ende des Schwenkhebels 17 gegen das zugeordnete Ende des Stiels 1 anliegt, in der also der Schwenkhebel um mehr als 90° gegenüber der Stellung nach Fig. verschwenkt ist, sind die Stellglieder 15 aus ihrer Stellung nach Fig. 2 über eine Stellung größten Abstandes zwischen der zugeordneten Unterseite des Führungs- und halteteils 2 und den Spannbügeln 14 gerinfügig hinausgeschwenkt. In dieser Stellung sind die in den Lagern 8 fest eingespannten Federbügel 7 so weit elastisch verspannt, daß die Klemmbügel 11 fest gegen die zugeordneten hinteren Wandungen der Klemmlöcher13 anliegen. Die Haltehaken 12 greifen hierbei fest unter die Unterseite des quaderförmigen Borstenkörpers 6. Gleichzeitig werden die Befestigungsschenkel 3 gegen die gegenüberliegenden Vorderwände der Haltelöcher4 gepreßt und bilden hier ein Widerlager.In the position shown in FIG. 3, in which the end of the pivot lever 17 provided with the control button 19 bears against the associated end of the handle 1, in which the pivot lever is pivoted by more than 90 ° with respect to the position according to FIG the actuators 15 from their position according to FIG. 2 over a position of greatest distance between the associated underside of the guide and holding part 2 and the clamping bracket 14 slightly pivoted. In this position, the spring clips 7 firmly clamped in the bearings 8 are elastically clamped so far that the clamping clips 11 lie firmly against the associated rear walls of the clamping holes 13. The holding hooks 12 grip firmly under the underside of the cuboid-shaped bristle body 6. At the same time, the fastening legs 3 are pressed against the opposite front walls of the holding holes 4 and form an abutment here.

Wie insbesondere aus den Fig.2 2 und 3 hervorgeht, sind die Schenkel 16 des Schwenkhebels 17 abgekröpft, so daß sie in der verspannten Stellung gemäß Fig. zum einen von der Unterseite des Führungs- und Halteteils zu dessen Oberseite durch die Schlitze 18 geführt werden können, im Bereich ihres gemeinsamen Endes mit dem Bedienungsknopf 19 aber bündig zum Stiel 1 liegen. Durch dieses Abkröpfen wird es gleichzeitig ermöglicht, eine Verschwenkbarkeit um mehr als 90° vorzusehen, so daß das geschilderte Verschwenken über den Totpunkt, in dem die größte Verspannung der Spannbügel 14 gegeben ist, möglich ist. Der Schwenkhebel braucht keine gesonderten Lager, da die gleichzeitig auch als Schwenkzapfen dienenden Stellglieder 15 ausreichend fest zwischen der Unterseite des Führungs- und Halteteils 2 einerseits und den Spannbügeln 14 der Federbügel 7 anderseits gehalten wird. Lediglich um ein Abrutschen des Schwenkhebels 17 zum unteren Rand 10 hin zu verhindern, sollte vor diesem unteren Rand ein Anschlag 20 für jedes Stellglied 15 vorgesehen sein.As can be seen in particular from FIGS. 2 and 3, the legs 16 of the pivoting lever 17 are bent so that they are guided through the slots 18 from the underside of the guide and holding part to the top thereof in the tensioned position according to FIG can, however, be flush with the handle 1 in the area of their common end with the control button 19. This cranking makes it possible at the same time to provide a pivotability of more than 90 °, so that the pivoting described above the dead center, in which the greatest tensioning of the clamping bracket 14 is given, is possible. The pivot lever does not need any separate bearings, since the actuators 15, which also serve as pivot pins, are held sufficiently firmly between the underside of the guide and holding part 2, on the one hand, and the clamping brackets 14 of the spring clips 7, on the other hand. Only in order to prevent the pivoting lever 17 from slipping towards the lower edge 10, a stop 20 should be provided for each actuator 15 in front of this lower edge.

Außer für Besen oder Schrubber kann die dargestellte und beschriebene Stielbefestigung beispielsweise auch für Fensterwischer, Wasserschieber und in ihrer Form artverwandte Gartengeräte, wie Rechen, hacken und dgl. verwendet werden.In addition to brooms or scrubbers, the handle attachment shown and described can also be used, for example, for window wipers, water slides and garden tools of a similar type, such as rakes, hoes and the like.
