Description

Die Erfindung betrifft eine Vorrichtung zum lösbaren Befestigen von Reinigungsgeräten, wie Besen, Schrubbern oder dergleichen an einem Stiel, der an seinem Ende Zwei gabelförmige, federnde Arme aufweist, die mittels einer Spanneinrichtung in Bohrungen des Reinigungsgerätes verspannbar sind, wobei die Spanneinrichtung eine Handhabe und ein zwischen den Armen angeordnetes Betätigungselement aufweist, das über Kontaktflächen mit den Armen in Anlage steht und diese durch Drehen oder Verschieben nach außen spreizt oder nach innen zieht.The invention relates to a device for detachable Attach cleaning devices such as brooms, scrubbers or the like on a stem that ends at two has fork-shaped, resilient arms, which by means of a Clamping device in the holes of the cleaning device can be clamped, the clamping device being a handle and an actuator located between the arms has that over contact surfaces with the arms in the plant and this by turning or moving spreads outwards or pulls inwards.

Es sind eine Vielzahl von derartigen Stielbefestigungen bekannt, die ein einfaches und schnelles Austauschen von abgenutzten oder verbrauchten Reinigungsgeräten oder auch ein Wechsel zwischen verschiedenen Reinigungsgeräten ermöglichen. In der DE-C-26 06 400 ist eine gattungsgemäße Stielbefestigung beschrieben, bei der ein Knebelkörper zwischen den gabelförmigen federnden Armen angeordnet und drehbar gelagert ist. Mit dem Knebelkörper ist ein Handgriff verbunden, der dem Benutzer das Drehen des Knebelkörpers ermöglicht. Der Knebelkörper steht über Kontaktflächen mit der Innenseite der Arme in Anlage. Die Kontaktflächen sind so geformt, daß die Arme bei Drehung des Knebelkörpers nach außen gespreizt werden, wodurch eine Verspannung mit dem Reinigungsgerät zu erzielen ist. Wenn der Knebelkörper zurückgedreht wird, können die Arme aufgrund ihrer Federkraft in ihre nach innen gezogene Position zurückkehren.There are a variety of such handle attachments known for an easy and quick replacement of worn or used cleaning devices or also a change between different cleaning devices enable. In DE-C-26 06 400 is a generic handle attachment described in which a gag between the fork-shaped resilient arms arranged and rotatable is stored. With the gag body is a handle connected to the user rotating the gag body enables. The gag body stands over contact surfaces with the inside of the arms in contact. The contact areas are shaped so that the arms rotate when the gag body be spread outwards, causing a bracing can be achieved with the cleaning device. If the The gag body is turned back, the arms may be due their spring force in their inwardly pulled position to return.

Es hat sich gezeigt, daß sich mit der bekannten Stielbefestigung zwar auch von ungeübten Personen ein Austauschen oder Auswechseln des Reinigungsgerätes in einfacher und schneller Weise erreichen läßt, jedoch besteht die Gefahr, daß sich im Laufe der Zeit zwischen den Kontaktflächen des Knebelkörpers und den entsprechenden Flächen der Arme Schmutz und Staub ansammelt, die die Reibung zwischen diesen Bauteilen wesentlich erhöhen, so daß relativ große Kräfte aufzuwenden sind, um den Knebelkörper drehen und somit die Arme verspannen zu können. Dies kann die Verwendung der Stielbefestigung wesentlich erschweren oder für Anwender mit nur geringen Körperkräften sogar unmöglich machen.It has been shown that with the known handle attachment an exchange even by inexperienced people or changing the cleaning device in simple and can be reached more quickly, but it does exist Danger that between the contact surfaces over time of the gag body and the corresponding surfaces the poor accumulates dirt and dust which is the friction between these components significantly increase so that relatively large forces are to be applied to the gag body to rotate and thus to be able to tension the arms. This the use of the handle attachment can be essential difficult or for users with little physical strength even make it impossible.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art zu schaffen, bei der auch nach längerem Gebrauch eine einfache und leichtgängige Verstellbarkeit gewährleistet ist.The invention has for its object a device to create of the type mentioned, even after easy use for longer periods of time is guaranteed.

Diese Aufgabe wird bei einer Vorrichtung zum lösbaren Befestigen von Reinigungsgeräten erfindungsgemäß dadurch gelöst, daß die Kontaktflächen des Betätigungselementes an drehbaren Lagerteilen ausgebildet sind, die bei der Verstellbewegung des Betätigungselementes an den Armen abrollen. This object is achieved in a device for solvable Fastening cleaning devices according to the invention solved that the contact surfaces of the actuator are formed on rotatable bearing parts which at Adjustment movement of the actuator on the arms unroll.

Auf diese Weise ist erfindungsgemäß die bei der bekannten Ausführungsform auftretende Gleitbewegung zwischen dem Betätigungselement, bei dem es sich vorzugsweise um einen an der Handhabe angebrachten oder einstückig mit dieser verbundenen Knebelkörper handelt, und den Armen bzw. die dabei auftretende Gleitreibung durch eine Abrollbewegung bzw. eine Rollreibung ersetzt. Es hat sich gezeigt, daß auf diese Weise 30% bis 40% geringere Betätigungskräfte von einem Benutzer aufzubringen sind, um den Knebelkörper zu verstellen und die Arme zu verspannen.In this way, according to the invention, that in the known Embodiment occurring sliding movement between the Actuator, which is preferably a attached to the handle or in one piece with it connected gag body, and the poor or the sliding friction that occurs as a result of a rolling movement or replaced a rolling friction. It has been shown that in this way 30% to 40% lower actuation forces are to be applied by a user to the gag body to adjust and brace your arms.

Wenn sich im Laufe der Zeit auf den drehenden Lagerteilen, bei denen es sich vorzugsweise um Lagerwalzen, oder -rollen handelt, Schmutz und Staub ansammeln sollte oder wenn die Oberflächen der üblicherweise aus Metall bestehenden Arme korrodieren sollten, dann ist das Abrollverhalten eher verbessert, da Gleiteffekte der Lagerteile vermieden werden. Dies kann auch erreicht werden, wenn die Oberflächen der Lagerteile und/oder der Arme aufgerauht sind.If over time the rotating bearing parts which are preferably bearing rollers, or -rolling, should collect dirt and dust or if the surfaces of those usually made of metal Arms should corrode, then the rolling behavior rather improved because the bearing parts slide be avoided. This can also be achieved if the surfaces of the bearing parts and / or the arms are roughened are.

Eine gute Führung der Arme an dem Knebelkörper bei der Verstellbewegung kann gewährleistet werden, wenn auf der Oberfläche der Lagerteile jeweils eine umlaufende Vertiefung ausgebildet ist, in der die Arme abrollen.A good guide of the arms on the gag body at the Adjustment movement can be guaranteed when on the Surface of the bearing parts each have a circumferential recess is formed in which the arms roll.

Die Lagerteile sind vorzugsweise drehbar an dem Knebelkörper gelagert, was durch nachträgliche Montage, beispielsweise Einprellen der Lagerteile in den Knebelkörper erreicht werden kann. Es ist jedoch auch möglich, den Knebelkörper und die Lagerteile aus unterschiedlichen Kunststoffen im Zweikomponenten-Spritzgußverfahren in einem Arbeitsgang herzustellen, so daß eine spezielle Montage entfallen kann. Dabei sollten der Knebelkörper und die Lagerteile aus verschiedenen Kunststoffen mit geringer gegenseitiger Reibung bestehen, so daß zwischen diesen Bauteilen eine nur geringe Lagerreibung auftritt.The bearing parts are preferably rotatable on the toggle body stored what by subsequent assembly, for example Bump the bearing parts into the gag body can be reached. However, it is also possible to Toggle body and the bearing parts from different Plastics in two-component injection molding in manufacture in one operation so that a special Assembly can be omitted. The gag should and the bearing parts made of different plastics there is little mutual friction, so that between only a slight bearing friction occurs in these components.

Wenn die Lagerteile Lagerwalzen oder -rollen sind, sollte vorzugsweise vorgesehen sein, daß die Drehachse der Lagerwalzen oder -rollen senkrecht zur Spreizrichtung der Arme verlaufen.If the bearing parts are bearing rollers or rollers, should preferably be provided that the axis of rotation of the Bearing rollers or rollers perpendicular to the direction of expansion of the Arms run.

In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, daß zumindest zwei drehbare Lagerteile vorgesehen sind, von denen jeweils eines an jedem Arm anliegt. Die beiden Lagerteile sind dabei beispielsweise diametral gegenüberliegend bezüglich des Drehpunktes des Knebelkörpers angeordnet und stehen zumindest über einen großen Teil des Schwenkbereichs des Knebelkörpers mit den Armen in Anlage. Wenn die Lagerteile, d.h. die Lagerwalzen oder -rollen unmittelbar vor Erreichen der nach innen gezogenen Stellung der Armen von diesen freikommen, sollten an dem Knebelkörper zumindest zwei Querstege mit Anlageflächen vorgesehen sein, die die Arme in ihrem nach innen gezogenen Zustand auf Abstand halten. Auf diese Weise läßt sich eine stetige störungsfreie Schwenkbewegung erreichen, da der Knebelkörper beim Schwenken in praktisch allen Stellungen geführt ist.In a preferred embodiment of the invention, that at least two rotatable bearing parts are provided are, one on each arm. The two bearing parts are, for example, diametrical opposite with respect to the pivot point of the gag body arranged and stand at least over a large one Part of the swivel range of the toggle body with the arms in Appendix. If the bearing parts, i.e. the bearing rollers or -roll immediately before reaching the inside Position of the poor to get rid of these should the gag body at least two crossbars with contact surfaces be provided which the arms in their inward Keep the pulled condition at a distance. In this way allows a steady, trouble-free swivel movement reach because the gag body when swiveling in practical all positions.

In Weiterbildung der Erfindung kann vorgesehen sein, daß an den Lagerteilen von außen sichtbare Markierungen angebracht sind, so daß der Benutzer bei der Schwenkbewegung feststellen kann, ob die Lagerteile an den Armen abrollen oder nicht, und im Bedarfsfall eine Behinderung der Lagerteile beseitigen kann. Vorzugsweise sollten die Markierungen an der Stirnseite der Lagerwalzen bzw. -rollen angeordnet sein.In a further development of the invention it can be provided that Markings visible from the outside on the bearing parts are attached so that the user during the pivoting movement can determine whether the bearing parts on the arms roll or not, and if necessary, a disability who can eliminate bearing parts. Preferably the Markings on the front of the bearing rollers or -rolled.

Der in Figur 1 dargestellte Stiel 1 besteht aus einem Rohr oder stabförmigen Abschnitt 2, an dessen unterem Ende zwei etwa parallel verlaufende, gabelartig ausgebildete Arme 3 und 4 angebracht sind, die bei dem Ausführungsbeispiel nach außen abgekröpfte Schenkel 6 und 7 und daran anschließend wiederum abgewinkelte Enden 8 und 9 aufweisen. Die Arme 3 und 4 werden mit ihren abgewinkelten Enden 8 und 9 in Bohrungen 32 und 33 eingesteckt, die in einem Borstenkörper 31 eines Reinigungsgerätes 30 in Form eines Besens eingesteckt werden können.The stem 1 shown in Figure 1 consists of a Pipe or rod-shaped section 2, on the lower End two approximately parallel, fork-shaped Arms 3 and 4 are attached in the embodiment outwardly bent legs 6 and 7 and followed by angled ends 8 and 9 exhibit. Arms 3 and 4 are angled with their Ends 8 and 9 inserted into holes 32 and 33, the in a bristle body 31 of a cleaning device 30 in Form of a broom can be inserted.

Zwischen den Armen 3 und 4 ist eine Spanneinrichtung eingesetzt, die eine Handhabe in Form eines länglichen Handgriffs 13 besitzt. Die Spanneinrichtung 10 ist in den Figuren 2 bis 5 im einzelnen dargestellt.Between the arms 3 and 4 is a tensioning device used a handle in the form of an elongated Handle 13 has. The clamping device 10 is in the Figures 2 to 5 shown in detail.

Die Spanneinrichtung 10 umfaßt einen Knebelkörper 17, der auf seiner Unterseite von einer einstückig angeformten unteren Scheibe 12 und auf seiner Oberseite von einer ebenfalls einstückig angeformten oberen Scheibe 11 begrenzt ist. Die obere Scheibe 11 weist eine längliche, gegenüber der unteren Scheibe verlängerte Form auf und dient als Basis für den senkrecht dazu verlaufenden Handgriff 13, der einstückig mit der oberen Scheibe 11 ausgeformt ist. Auf den Oberflächen des Handgriffs 13 sind längs verlaufende Erhebungen 14 ausgebildet, die die Griffigkeit des Handgriffs erhöhen sollen. Der vordere, dreieckförmig ausgestaltete Abschnitt 13a des Handgriffs 13 dient der Daumenauflage, wodurch bei gleichem Krafteinsatz das Drehmoment erhöht und die Betätigung erleichtert werden kann.The tensioning device 10 comprises a toggle body 17 which on its underside from a one-piece lower disc 12 and on its top by one also integrally molded upper disc 11 limited is. The upper disc 11 has an elongated, elongated form on and below the lower disc serves as the basis for the perpendicular Handle 13, which is integral with the upper disc 11th is formed. On the surfaces of the handle 13 longitudinal projections 14 are formed which the Grip of the handle should increase. The front one triangular section 13a of the handle 13 serves the thumb rest, whereby with the same force the torque increases and the operation is easier can be.

Zwischen die untere Scheibe 12 und die obere Scheibe 11 sind die Arme 3 und 4 einsetzbar, so daß sie dazwischen geführt sind. In zwei zur Längsachse L diametral gegenüberliegende Durchgangsbohrungen in der oberen und unteren Scheibe 11 bzw. 12 sind jeweils eine Lagerwalze 20 bzw. 21 eingeprellt, die drehbar in den Durchgangsbohrungen gehalten sind. Wie Figur 5 zeigt, besitzen die Lagerwalzen 20 und 21 auf ihrer Mantelfläche jeweils eine umlaufende Vertiefung 20a bzw. 21a, in der die Arme 3 bzw. 4 anliegen und geführt sind. Der Knebelkörper 17 und die Lagerwalzen 20, 21 bestehen aus verschiedenen Kunststoffen mit geringer gegenseitiger Reibung, so daß eine leichtgängige Drehbewegung der Lagerwalzen 20, 21 in dem Knebelkörper 17 gewährleistet ist.Between the lower disc 12 and the upper disc 11 the arms 3 and 4 can be used so that they are in between are led. In two diametrically opposite to the longitudinal axis L. Through holes in the upper and lower Discs 11 and 12 are each a bearing roller 20 or 21, which rotated in the through holes are held. As shown in Figure 5, the bearing rollers 20 and 21 each on their lateral surface circumferential depression 20a or 21a, in which the arms 3 or 4 and are guided. The gag body 17 and the bearing rollers 20, 21 consist of different plastics with little mutual friction, so that a smooth rotation of the bearing rollers 20, 21 in the Gag body 17 is guaranteed.

Wie insbesondere Figur 3 zeigt, sind an dem Knebelkörper senkrecht zur Verbindungslinie zwischen den Lagerwalzen 20, 21, d.h. in Richtung der Längsachse L zwei in entgegengesetzte Richtung weisende Querstege 15 und 16 angeformt, die an ihrem Ende jeweils eine Anlagefläche 15a bzw. 16a aufweisen. Die Anlagenflächen 15a und 16a sind vom Drehpunkt D des Knebelkörpers weniger weit entfernt als die Außenflächen der Lagerwalzen 20 und 21.As particularly shown in Figure 3, are on the gag body perpendicular to the connecting line between the bearing rollers 20, 21, i.e. in the direction of the longitudinal axis L two in opposite Molded cross bars 15 and 16 pointing in the direction which each have a contact surface 15a at their end or 16a. The plant surfaces 15a and 16a are less distant from the pivot point D of the toggle body than the outer surfaces of the bearing rollers 20 and 21.

In den Figuren 6, 7 und 8 sind die einzelnen Phasen der Spannbewegung der Arme 3 und 4 gezeigt. In der in Figur 6 gezeigten Stellung befinden sich die Arme 3 und 4 in ihrer nach innen gezogenen Stellung, in der sie in die Bohrungen 32 und 33 des Borstenkörpers 1 eingesetzt werden können. Die Lagerwalzen 20 und 21 sowie die Querstege 15 und 16 sind zwischen nach außen gekrümmten Abkröpfungen 5 der Arme 3 und 4 aufgenommen, wobei die Arme 3 und 4 an den Anlageflächen 15a und 16a der Querstege 15 und 16 anliegen. Durch Drehung des Handgriffs bzw. des Knebelkörpers 17 in Richtung des Pfeils P kommen die Lagerwalzen 20 und 21 mit der Innenseite der gekrümmten Abkröpfungen 5 der Arme 3 und 4 in Anlage, während die Anlageflächen 15a und 16a der Querstege 15 und 16 von den Armen 3 und 4 freikommen. Da der Abstand der äußeren Flächen der Lagerwalzen 20 und 21 größer ist als der gegenseitige Abstand der Anlageflächen 15a und 16a der Querstege 15 und 16 werden die Arme 3 und 4 bei Drehung des Knebelkörpers 17 gespreizt, wie aus der in Figur 7 dargestellten Zwischenstellung ersichtlich ist. Während der Verstellbewegung rollen die Lagerwalzen 20 und 21 an den Armen 3 und 4 ab, so daß nur geringe Reibung auftritt.In Figures 6, 7 and 8, the individual phases of the Tensioning movement of arms 3 and 4 shown. 6 position shown are the arms 3 and 4 in its inwardly drawn position, in which it moves into the Bores 32 and 33 of the bristle body 1 are used can be. The bearing rollers 20 and 21 and the crossbars 15 and 16 are between outwardly curved Cranks 5 of the arms 3 and 4 added, the Arms 3 and 4 on the contact surfaces 15a and 16a of the crosspieces 15 and 16 are present. By turning the handle or the toggle body 17 come in the direction of arrow P. the bearing rollers 20 and 21 with the inside of the curved Cranks 5 of the arms 3 and 4 in plant while the contact surfaces 15a and 16a of the crossbars 15 and 16 from free the poor 3 and 4. Because the distance of the outer Areas of the bearing rollers 20 and 21 is larger than that mutual distance between the contact surfaces 15a and 16a Crossbars 15 and 16 become arms 3 and 4 when rotating of the gag body 17 spread, as shown in FIG. 7 intermediate position shown can be seen. While the adjustment movement roll the bearing rollers 20 and 21 the arms 3 and 4, so that there is little friction.

In Figur 8 ist der am weitesten gespreizte Zustand der Arme 3 und 4 erreicht, wobei die beiden Lagerwalzen 20 und 21 im wesentlichen senkrecht zur Längsrichtung der Arme 3 und 4 angeordnet sind und deren gegenseitigen Abstand bestimmen. Mittels eines an der oberen Scheibe 11 angeformten Vorsprung 18, der zwischen die Arme 3 und 4 einschnappen kann, ist ein unbeabsichtigtes Verstellen aus dieser gespreizten Spannlage verhindert.In Figure 8, the most spread state is Arms 3 and 4 reached, the two bearing rollers 20th and 21 substantially perpendicular to the longitudinal direction of the Arms 3 and 4 are arranged and their mutual Determine distance. By means of a on the upper disc 11 molded projection 18 between the arms 3 and 4th can snap in, is an unintentional adjustment prevented from this spread clamping position.

Um die Arme 3 und 4 aus ihrem Eingriff mit dem Reinigungsgerät zu lösen, wird der Knebelkörper 17 aus der in Figur 8 gezeigten Stellung in die in Figur 6 gezeigte Stellung zurückgedreht, wobei die Arme 3 und 4 aufgrund ihrer Federkraft in ständiger Anlage mit den Lagerwalzen 20 und 21 bzw. den Anlageflächen 15a und 16a der Querstege 15 und 16 bleiben.To arms 3 and 4 out of engagement with the cleaning device to solve, the gag body 17 from the in Figure 8 position shown in the figure 6 shown Position turned back, with arms 3 and 4 due their spring force in constant contact with the bearing rollers 20 and 21 or the contact surfaces 15a and 16a of the crosspieces 15 and 16 remain.
