Description

Die Erfindung betrifft eine Filtersperre an einem Staubsauger, der einen durch einen Deckel verschließbaren Staubraum aufweist, welche Filtersperre aus mindestens einem am Staubsaugergehäuse angeordneten, durch Federkraft in den Schließweg des Deckels schwenkbaren Hebel besteht, der in einer an der Halteplatte des in den Staubraum einsetzbaren Filterbeutels vorgesehenen öffnung verhakbar und dadurch außerhalb des Schließweges gehalten ist.The invention relates to a filter lock on a vacuum cleaner which has a dust chamber which can be closed by a lid, which filter lock consists of at least one lever which is arranged on the vacuum cleaner housing and can be pivoted by spring force into the closing path of the lid and which is in a on the holding plate of the filter bag which can be inserted into the dust chamber provided opening can be hooked and thereby kept outside the closing path.

Eine solche Filtersperre ist durch die DE-OS 27 30 894 bekannt. Bei dieser Filtersperre sind an den beiden Seitenwänden des Staubraumes verschwenkbare Hebel angeordnet, die eine Auflagefläche für die Halteplatte des Filterbeutels aufweisen. Im Bereich der Auflagefläche ist an jedem Hebel ein Zapfen vorgesehen, der in eine entsprechende Öffnung der Halteplatte eingreift. Beim Herausnehmen des Filterbeutels aus dem Staubraum wird die Halteplatte von den Zapfen abgehoben, wodurch die Hebel freigegeben und unter der Einwirkung einer Feder nach außen geschwenkt werden. In dieser Stellung ragen die Hebel in den Schließweg des Staubraumdeckels. Um die Hebel wieder aus dem Schließweg zu entfernen, muß ein neuer Filterbeutel eingesetzt werden, durch dessen auf die Zapfen aufgesteckte Halteplatte die Hebel wieder in der Freigabestellung gehalten werden. Das Einsetzen des Filterbeutels gestaltet sich relativ umständlich, da mit beiden Händen die Hebel nach innen geschwenkt werden müssen, damit die Halteplatte auf die Auflagefläche des Hebels aufgelegt und auf die Zapfen aufgesteckt werden kann.Such a filter lock is known from DE-OS 27 30 894. In this filter lock, pivotable levers are arranged on the two side walls of the dust chamber, which have a bearing surface for the holding plate of the filter bag. In the area of the support surface, a pin is provided on each lever, which engages in a corresponding opening in the holding plate. When the filter bag is removed from the dust chamber, the holding plate is lifted off the pins, whereby the levers are released and pivoted outwards under the action of a spring. In this position, the levers protrude into the closing path of the dust compartment cover. In order to remove the levers from the closing path again, a new filter bag has to be inserted, by means of which the holding plate, which is attached to the pin, holds the levers again in the release position. The insertion of the filter bag is relatively cumbersome since the levers must be pivoted inwards with both hands so that the holding plate can be placed on the bearing surface of the lever and attached to the pin.

Der Erfindung liegt die Aufgabe zugrunde, eine Filtersperre der eingangs beschriebenen Art so auszubilden, daß das Einsetzen eines Filterbeutels in den Staubraum und dessen Ankoppeln an die Elemente der Filtersperre wesentlich vereinfacht ist.The invention has for its object to design a filter lock of the type described above so that Inserting a filter bag in the dust chamber and coupling it to the elements of the filter lock is considerably simplified.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß der Hebel an der den Saugstutzen enthaltenden Vorderwand des Staubraumes angeordnet ist und die Halteplatte einen senkrechten Einschnitt aufweist, in den der Hebel von Hand einschwenkbar ist, daß ferner die öffnung seitlich von dem Einschnitt liegt und seitlich am Hebel ein entsprechender Sperrhaken vorgesehen ist, der beim Verschwenken des Hebels in den Einschnitt in die öffnung einrastet. Erst nachdem der Filterbeutel in den Staubraum eingesetzt ist, wird der Hebel verschwenkt. Beim Verschwenken wird der Hebel in dem senkrechten Einschnitt geführt, so daß dadurch die Halteplatte und der Hebel aufeinander ausgerichtet werden und der Sperrhaken die öffnung nicht verfehlen kann.The object is achieved according to the invention in that the lever is arranged on the front wall of the dust chamber containing the suction port and the holding plate has a vertical incision into which the lever can be pivoted by hand, that the opening is also located to the side of the incision and a corresponding locking hook is provided on the side of the lever, which engages when the lever is pivoted into the incision in the opening. The lever is only pivoted after the filter bag has been inserted into the dust chamber. When pivoting, the lever is guided in the vertical incision, so that the holding plate and the lever are thereby aligned with one another and the locking hook cannot miss the opening.

Eine besonders vorteilhafte Ausführungsform der Erfindung ist dadurch gekennzeichnet, daß der Einschnitt an der Halteplatte die Form eines auf dem Kopf stehenden T hat und die seitlich überstehenden Einschnitte des T-Balkens als Rastöffnungen für zu beiden Seiten des Hebels angeordnete Sperrhaken dienen. Durch diese T-förmige Gestalt des Einschnittes ergeben sich zwei parallel zu dem senkrechten Teil des Einschnittes verlaufende Lappen der Halteplatte, die eine ausreichende Elastizität aufweisen, damit die Sperrhaken an diesen Lappen vorbei in den quer verlaufenden Teil des T-förmigen Einschnittes bewegt werden können. Eine gesonderte Anordnung einer den Hebel verschwenkenden Feder erübrigt sich dadurch, daß an dem Hebel ein federnder Sporn angeformt ist, der sich an der Wand des Staubsaugergehäuses abstützt.A particularly advantageous embodiment of the invention is characterized in that the incision on the holding plate has the shape of an upside-down T and the laterally protruding incisions of the T-bar serve as latching openings for locking hooks arranged on both sides of the lever. This T-shaped shape of the incision results in two flaps of the holding plate which run parallel to the vertical part of the incision and which have sufficient elasticity so that the locking hooks can be moved past these flaps into the transverse part of the T-shaped incision. A separate arrangement of a spring pivoting the lever is unnecessary in that a resilient spur is formed on the lever, which is supported on the wall of the vacuum cleaner housing.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispiels wird der Anmeldungsgegenstand nachfolgend näher beschrieben. Es zeigt

  • Fig. 1 die Anordnung einer Filtersperre im Schnitt,
  • Fig. 2 eine Teilansicht der Filtersperrenanordnung nach Fig. 1,
  • Fig. 3 eine Draufsicht einer Halteplatte eines Filterbeutels.
The subject of the application is described in more detail below using an exemplary embodiment shown in the drawing. It shows
  • 1 shows the arrangement of a filter lock in section,
  • 2 shows a partial view of the filter lock arrangement according to FIG. 1,
  • Fig. 3 is a plan view of a holding plate of a filter bag.

Mit 1 ist die Vorderwand des Staubraumes eines Staubsaugers bezeichnet, an der der Saugstutzen 2 des Staubsaugers angeordnet ist. An den Saugstutzen 2 ist ein Filterbeutel mit seiner Halteplatte 3 angeschlossen. An der Vorderwand 1 ist ferner ein Hebel 4 mittels einer Schwenkachse 5 angelenkt. Ober die Schwenkachse 5 hinaus ist an dem Hebel 4 ein Sporn 6 angeformt, der sich mit seinem freien Ende 7 an einer Anlaufschräge 8 der Vorderwand 1 abstützt und infolge seiner Elastizität eine Verschwenkkraft auf den Hebel 4 ausübt. An dem Hebel 4 ist ferner seitlich ein Sperrhaken 9 angeformt, der in eine an der Halteplatte 3 vorgesehene Öffnung 10 eingreift. Hierdurch wird der Hebel 4 entgegen der von dem Sporn 6 ausgeübten Verschwenkkraft in der gezeigten Stellung gehalten. Der Staubraum des. Staubsaugers ist durch einen Deckel 11 verschlossen.With 1 the front wall of the dust chamber of a vacuum cleaner is designated, on which the suction nozzle 2 of the vacuum cleaner is arranged. A filter bag with its holding plate 3 is connected to the suction nozzle 2. A lever 4 is also articulated on the front wall 1 by means of a pivot axis 5. Above the pivot axis 5, a spur 6 is formed on the lever 4, which is supported with its free end 7 on a run-up slope 8 of the front wall 1 and exerts a pivoting force on the lever 4 due to its elasticity. A locking hook 9 is also formed laterally on the lever 4 and engages in an opening 10 provided on the holding plate 3. As a result, the lever 4 is held in the position shown against the pivoting force exerted by the spur 6. The dust chamber of the vacuum cleaner is closed by a cover 11.

Wie die Draufsicht nach Fig. 2 zeigt, liegt dem Hebel 4 ein senkrechter Einschnitt 12 der Halteplatte 3 gegenüber. Die Fig. 3 zeigt die T-förmige Gestalt, die der senkrechte Einschnitt 12 zusammen mit den seitlich angeordneten Öffnungen 10 in der Halteplatte 3 bildet.As the plan view according to FIG. 2 shows, the lever 4 is opposite a vertical incision 12 in the holding plate 3. 3 shows the T-shaped shape which the vertical incision 12 forms together with the laterally arranged openings 10 in the holding plate 3.

Wird ein gefüllter Filterbeutel aus dem Staubraum entnommen, so wird der Hebel 4 durch die federnde Kraft des Spornes 6 in die in Fig. 1 gestrichelt angedeutete Stellung verschwenkt. In dieser Stellung ragt der Hebel 4 in den Schließweg des Deckels 11, der - wie in Fig. 1 ebenfalls gestrichelt angedeutet - daraufhin nicht in seine Schließstellung gebracht werden kann. Nach dem Einlegen eines neuen Filterbeutels wird der Hebel 4 in den senkrechten Einschnitt 12 der Halteplatte 3 geschwenkt, wobei die seitlich an dem Hebel 4 angeordneten Sperrhaken 9, die parallel zu dem senkrechten Einschnitt 12 verlaufenden Lappen 13 an der Halteplatte 3 etwas wegdrücken und an diesen Lappen 13 entlang in die Öffnungen 10 gleiten. Damit ist der Hebel 4 in den Öffnungen 10 verhakt und wird in der niedergedrückten Stellung gehalten, so daß der Deckel 11 geschlossen werden kann.If a filled filter bag is removed from the dust space, the lever 4 is pivoted by the resilient force of the spur 6 into the position indicated by dashed lines in FIG. 1. In this position, the lever 4 protrudes into the closing path of the cover 11, which - as also indicated by dashed lines in FIG. 1 - cannot then be brought into its closed position. After inserting a new filter bag, the lever 4 is pivoted into the vertical cut 12 of the holding plate 3, the side of the Lever 4 arranged locking hooks 9, which push flaps 13 running parallel to the vertical incision 12 on the holding plate 3 somewhat and slide along these flaps 13 into the openings 10. So that the lever 4 is hooked in the openings 10 and is held in the depressed position so that the lid 11 can be closed.
