Description

Die Erfindung betrifft eine Vorrichtung für die Befestigung von Besenkörpern, Schrubberkörpern, Mopkörpern und dergleichen an einem Stiel, nachfolgend der Einfachheit halber generell als Besenkörper bezeichnet, nach dem Oberbegriff des Anspruches 1.The invention relates to a device for fastening broom bodies, scrubbing bodies, mop bodies and the like to a handle, hereinafter referred to generally as broom bodies for the sake of simplicity.

Bei einer bekannten gattungsgemäßen Einrichtung (DE-U-7 734 201) sind für die Befestigung des Stieles am Besenkörper in diesem vier Bohrungen vorgesehen. In zwei dieser Bohrungen werden die Enden von stärkeren Drähten eingeführt und in die anderen beiden Bohrungen die Enden von federnden Drähten. Auf den Drähten läuft ein Schieber. Wird dieser längs der Drähte verschoben, verklemmen sich die Drahtenden in den Bohrungen des Besenkörpers. Diese Einrichtung ist mit dem eigentlichen Besenstiel verbunden oder verbindbar.In a known generic device (DE-U-7 734 201) four holes are provided in the broom body for fastening the handle. The ends of thicker wires are inserted into two of these holes and the ends of resilient wires into the other two holes. A slider runs on the wires. If this is moved along the wires, the wire ends jam in the bores of the broom body. This device is connected or connectable to the actual broomstick.

Bei dieser Einrichtung kommt es vor, daß trotz vorgesehener seitlicher Rastrillen bei Einwirken eines Stoßes in Richtung des Besenstieles auf den Besenkörper der Schieber verrutscht. Die Drähte verlieren dann ihre Spannung, und der Besenkörper fällt von der Befestigungsvorrichtung ab. Des weiteren treten die federnden Drähte mit ihren freien Enden aus dem Schieber heraus, wenn dieser in Richtung auf den Besen zu verschoben wird, wodurch eine Verletzungsgefahr an den Enden der Drähte gegeben ist.With this device, it happens that, despite the provided lateral locking grooves, the slider slips under the action of an impact in the direction of the broom handle on the broom body. The wires lose then their tension, and the broom body falls off the fastener. Furthermore, the resilient wires come out of the slider with their free ends when the slider is displaced towards the broom, whereby there is a risk of injury at the ends of the wires.

Gemäß der EP-A-019 833 ist für die Befestigung der Drahtenden in den Ausnehmungen des Besenkörpers ein Schwenkhebel vorgesehen. Dieser verhindert zwar eine Verletzungsgefahr, da er als Bügel ausgebildet ist, ein derartiger Bügel kann sich aber leicht hinter Ecken und Kanten beispielsweise eines Möbelstückes legen und deshalb beim Bewegen des Besens ungewollt verschwenkt werden, so daß sich der Besenkörper von selbst löst.According to EP-A-019 833, a pivot lever is provided for fastening the wire ends in the recesses in the broom body. Although this prevents a risk of injury since it is designed as a bracket, such a bracket can easily lie behind corners and edges of a piece of furniture, for example, and therefore be unintentionally pivoted when the broom is moved, so that the broom body loosens itself.

Aufgabe der Erfindung ist es, eine lösbare Stielbefestigung der gattungsgemäßen Art derart zu verbessern, daß sie einfach in ihrem Aufbau und weniger störanfällig ist und andererseits eine bequeme Handhabung für das Lösen und Spannen der federnden Drähte gewährleistet, ohne daß die Gefahr einer Verletzung an den Enden der Drähte besteht.The object of the invention is to improve a releasable handle attachment of the generic type in such a way that it is simple in its construction and less prone to failure and, on the other hand, ensures comfortable handling for loosening and tensioning the resilient wires , without the risk of injury at the ends the wires are made.

Diese Aufgabe wird durch das kennzeichnende Merkmal des Anspruches 1 gelöst.This object is achieved by the characterizing feature of claim 1.

Dadurch, daß jetzt eine Querverriegelung zur Befestigung des Besenkörpers an den Drähten der Verriegelungseinrichtung vorgesehen ist, können Stöße auf den Besen kein Lösen der Befestigungsmittel mehr verursachen. Außerdem können die Enden der federnden Drähte in dem Verriegelungskörper angeordnet werden, ohne mit ihren Enden aus diesem Körper herauszutreten, wie es zwangsläufig bei der verschiebbaren Verriegelungseinrichtung gemäß der DE-U-7 734 201 der Fall ist, so daß keine Verletzungsgefahr bei Bedienung der Verriegelungseinrichtung mehr möglich ist.The fact that a transverse locking device is now provided for fastening the broom body to the wires of the locking device means that bumps on the broom can no longer cause the fastening means to be released. In addition, the Ends of the resilient wires are arranged in the locking body without their ends coming out of this body, as is inevitably the case with the sliding locking device according to DE-U-7 734 201, so that there is no longer any risk of injury when operating the locking device .

Die Verriegelungseinrichtung weist zweckmäßig einen leicht erreichbaren Drehknopf auf, der in dem Verriegelungskörper drehbar gelagert ist, derart, daß sich die Querverriegelung nach dem Spannen der Federdrähte unter die stärkeren Drähte legt und sich hier abstützt. Die Enden der Querverriegelung rasten vorteilhaft mit Ausnehmungen in diese Drähte ein.The locking device expediently has an n easily accessible turning knob, which is rotatably mounted in the latch body such that the cross-locking after tensioning the spring wires inserted under the stronger wires and is supported here. The ends of the cross locking advantageously snap into these wires with recesses.

Weitere Einzelheiten der Erfindung können den abhängigen Ansprüchen entnommen werden.Further details of the invention can be found in the dependent claims.

Der Besenstiel (1) weist eine Aufnahmehülse (2) für das Ende (3) einer Befestigungsvorrichtung (13) für einen Besenkörper (14) auf. Die Befestigungsvorrichtung (13) besteht aus zwei stärkeren Drähten (4, 5), welche mit Enden (6, 7) in Ausnehmungen (8, 9) des Besenkörpers (14) angeordnet werden können. Die Drähte (4, 5) weisen abgewinkelte Teilstücke (10, 11) auf, derart, daß diese Teilstücke etwa parallel zur Achse (A-A) des Besenkörpers liegen. Zum Besenstiel (1) hin laufen die Drähte (4, 5) in Teilstücke (15, 16) aus, welche parallel zueinander unter Einhaltung eines Abstandes laufen. Sie sind zum Stiel (1) hin im Bereich (17, 18) zusammengeführt und liegen in der Aufnahmehülse (2) mit einer Schleife (12).The broom handle (1) has a receiving sleeve (2) for the end (3) of a fastening device (13) for a broom body (14). The fastening device (13) consists of two stronger wires (4, 5), which with Ends (6, 7) in recesses (8, 9) of the broom body (14) can be arranged. The wires (4, 5) have angled sections (10, 11) such that these sections are approximately parallel to the axis (AA) of the broom body. The wires (4, 5) run into sections (15, 16) towards the broomstick (1), which run parallel to one another while maintaining a distance. They are brought together in the area (17, 18) towards the stem (1) and lie in the receiving sleeve (2) with a loop (12).

Zur Festklemmung des Besenkörpers (14) auf den Enden (6, 7) der Drähte (4, 5) sind zwei weitere Ausnehmungen, vorzugsweise Bohrungen (26, 27) im Besenkörper (14) vorgesehen. In diese Bohrungen können die Enden (24, 25) von Federdrähten (20, 21) eingeführt werden. Die Drähte (20, 21) sind spiralförmig, das heißt mit Windungen (22, 23) um die querliegenden Teilstücke (10, 11) der dickeren Drähte (4, 5) herumgelegt, so daß ein Spiralfedereffekt erzielt wird. Die sich hieran anschließenden Enden (28, 29) der Drähte sind, wie in Fig. 1 gestrichelt eingezeichnet worden ist, U-förmig umgebogen und liegen in Längsnuten (30, 31) eines Körpers (19). Die U-förmigen Enden (28, 29) stützen sich federnd an den Seitenflächen der Längsnuten (30, 31) ab, so daß sie in diesen ohne besondere Befestigung eine feste Lage einnehmen. Der Körper (19) kann hierzu aus Kunststoff ausgebildet sein und in sich selbst leicht elastisch.To clamp the broom body (14) on the ends (6, 7) of the wires (4, 5), two further recesses, preferably bores (26, 27) are provided in the broom body (14). The ends (24, 25) of spring wires (20, 21) can be inserted into these bores. The wires (20, 21) are spiral, that is, with turns (22, 23) around the transverse sections (10, 11) of the thicker wires (4, 5), so that a spiral spring effect is achieved. The adjoining ends (28, 29) of the wires are bent into a U-shape, as has been drawn in dashed lines in FIG. 1, and lie in longitudinal grooves (30, 31) of a body (19). The U-shaped ends (28, 29) are resiliently supported on the side surfaces of the longitudinal grooves (30, 31), so that they assume a fixed position in these without special attachment. For this purpose, the body (19) can be made of plastic and in itself slightly elastic.

Zur Befestigung des Stieles (1) am Besenkörper (14) werden die Drahtenden (6, 7) der stärkeren Drähte (3, 4) in die Ausnehmungen (8, 9) eingeführt, ebenso die Drahtenden (24, 25) der federnden Drähte (20, 21) in die Bohrungen (26, 27) des Besenkörpers (14). Der Körper (19) nimmt hierbei die in Fig. 2 gestrichelt eingezeichnete Lage ein. Wird jetzt der Körper (19) in Richtung des Pfeiles (35) nach unten bewegt in die in Fig. 2 ausgezogene Lage (19a), dann werden die Drähte (20, 21) gespannt, und sie drücken den Besenkörper (14) in eine Lage, daß sich die Enden (6, 7) der stärkeren Drähte (4, 5) in den Ausnehmungen (8, 9) ebenfalls verklemmen. Die Verklemmung der Drähte (3, 4) in den Ausnehmungen (8, 9) sowie die Verklemmung der Drähte (20, 21) in den Bohrungen (26, 27) (Ausnehmungen) genügt, um den Stiel (1) über die Befestigungsvorrichtung fest mit dem Besenkörper (14) zu verbinden.To attach the handle (1) to the broom body (14), the wire ends (6, 7) of the thicker wires (3, 4) are inserted into the recesses (8, 9), as are the wire ends (24, 25) of the resilient wires ( 20, 21) in the bores (26, 27) of the broom body (14). The body (19) takes the one shown in dashed lines in FIG. 2 Location a. If the body (19) is now moved downward in the direction of the arrow (35) into the position (19a) drawn out in FIG. 2, the wires (20, 21) are tensioned and they push the broom body (14) into one Position that the ends (6, 7) of the thicker wires (4, 5) also jam in the recesses (8, 9). The jamming of the wires (3, 4) in the recesses (8, 9) and the jamming of the wires (20, 21) in the bores (26, 27) (recesses) is sufficient to secure the handle (1) over the fastening device to connect with the broom body (14).

Damit der Körper (19) in der Lage (19a) nach dem Herunterdrücken liegenbleibt, weist er eine Verriegelungseinrichtung (40) auf. Die Verriegelungseinrichtung (40) besteht aus einer Querverriegelung (41), die auf einer Drehachse (42) angeordnet ist. Die Achse (42) ist durch den Körper (19) geführt und läuft in einen Drehknopf (43) aus. Wird der Knopf (43) um seine Achse um 90° gedreht, legen sich die Teile (41a) und (41b) der Querverriegelung (41) unter die parallel zueinander liegenden Teilstücke (15, 16) der stärkeren Drähte (3, 4) und halten den Körper (19) in der Lage (19a) fest. Zur Entriegelung wird der Drehknopf um 90° gedreht. Der Körper (19) kann dann in die strichpunktierte Lage der Fig. 2 zurückgeschwenkt werden. Die Spannung in den Federn (20, 21) wird hierdurch aufgehoben, und die Drahtenden (24, 25) können aus den Bohrungen (26, 27) des Besenkörpers (14) herausgezogen werden.So that the body (19) remains in position (19a) after being pressed down, it has a locking device (40). The locking device (40) consists of a cross lock (41) which is arranged on an axis of rotation (42). The axis (42) is guided through the body (19) and ends in a rotary knob (43). If the knob (43) is rotated by 90 ° about its axis, the parts (41a) and (41b) of the cross lock (41) lie under the sections (15, 16) of the thicker wires (3, 4) and which are parallel to one another hold the body (19) in position (19a). To unlock, the rotary knob is turned by 90 °. The body (19) can then be pivoted back into the dot-dash position in FIG. 2. This releases the tension in the springs (20, 21) and the wire ends (24, 25) can be pulled out of the bores (26, 27) of the broom body (14).

Die Querverriegelung (41) weist zwei Ausnehmungen (44, 45) auf, welche sich in der verriegelten Stellung unter die Drahtstücke (15, 16) legen.The cross locking device (41) has two recesses (44, 45) which lie in the locked position under the wire pieces (15, 16).

Der Körper (19) weist eine Längsausnehmung (50) auf, durch die die Querverriegelung (41) zur Montage gesteckt werden kann, wenn sie in Längsrichtung ausgerichtet ist, wie in Fig. 3 dargestellt. Liegt die Querverriegelung (41) in der Verriegelungsstellung, das heißt quer zu den Drahtstücken (15, 16), wie in Fig. 1 dargestellt, dann liegt auch die Querverriegelung quer zur Längsausnehmung (50) und kann nicht herausfallen.The body (19) has a longitudinal recess (50) through which the cross lock (41) can be inserted for assembly if it is aligned in the longitudinal direction, as shown in FIG. 3. If the cross lock (41) is in the locked position, that is to say transversely to the wire pieces (15, 16), as shown in FIG. 1, then the cross lock is also transverse to the longitudinal recess (50) and cannot fall out.

Der Körper (19) greift mit einem Längsteil (33) zwischen die Teilstücke (15, 16) der Drähte (3, 4) und stützt sich hier an den Drähten ab, so daß er sich zwischen diesen Drahtstücken nicht verdrehen kann (Fig. 5).The body (19) engages with a longitudinal part (33) between the sections (15, 16) of the wires (3, 4) and is supported here on the wires so that it cannot twist between these pieces of wire (Fig. 5 ).

Der Körper (19) weist, wie in Fig. 4 dargestellt, eine Griffmulde (34) auf, in die beispielsweise der Daumen einer Hand gelegt werden kann, um den Körper (19) sicher gegen den Druck der Federn (20, 21) in die Lage (19a) drücken zu können.The body (19), as shown in FIG. 4, has a recessed grip (34), into which, for example, the thumb of one hand can be placed in order to securely hold the body (19) against the pressure of the springs (20, 21) to be able to press the position (19a).

Die stärkeren Drähte (3, 4) sind mit ihren Enden (6, 7), wie aus Fig. 2 zu erkennen ist, leicht nach unten abgewinkelt. Die federnden Drähte (20, 21) sind mit ihren Enden (24, 25) leicht nach oben abgewinkelt und liegen hinter dem Besenkörper oder gemäß Fig. 2 hinter Absätzen des Besenkörpers. Hierdurch wird eine gute Abstützung in den Ausnehmungen (8, 9 sowie 26, 27) erzielt sowie eine schnelle Spannung der Drähte (4, 5 sowie 20, 21) gegeneinander beim Verschwenken des Körpers (19) und damit eine gute und sichere Befestigung des Besenkörpers (15) an dem Stiel (1).The stronger wires (3, 4) are angled slightly downwards with their ends (6, 7), as can be seen from FIG. 2. The ends of the resilient wires (20, 21) are angled slightly upwards (24, 25) and lie behind the broom body or, according to FIG. 2, behind shoulders of the broom body. This provides good support in the recesses (8, 9 and 26, 27) and quick tension of the wires (4, 5 and 20, 21) against each other when the body (19) is pivoted and thus a good and secure attachment of the broom body (15) on the handle (1).

Sämtliche Teile der Haltevorrichtung sind auswechselbar. Nach einer Entriegelung der Querverriegelung (41) kann der Drehknopf (43) mit den Teilen (41a, 41b) durch die Längsnut (33) des Körpers (19) herausgezogen werden. Die U-förmig umgebogenen Teile (28, 29) können aus den Längsnuten (30, 31) des Körpers (19) herausgezogen werden, und die Spiralwindungen (22, 23) der Federdrähte können über die Teile (10, 11) der Drähte (4, 5) abgezogen werden.
In umgekehrter Weise läßt sich die Vorrichtung in einfachster Weise montieren.All parts of the holding device are interchangeable. After unlocking the cross lock (41), the rotary knob (43) with the parts (41a, 41b) can be pulled out through the longitudinal groove (33) of the body (19). The U-shaped bent parts (28, 29) can be pulled out of the longitudinal grooves (30, 31) of the body (19), and the spiral turns (22, 23) of the spring wires can be pulled over the parts (10, 11) of the wires ( 4, 5) are subtracted.
Conversely, the device can be assembled in the simplest way.
