Description

Die Erfindung betrifft einen Verschluß zum lösbaren Arretie­ren eines schwenkbar gelagerten Bauteiles an einem zugeordne­ten Wandabschnitt.The invention relates to a closure for releasably locking a pivotally mounted component to an associated wall section.

Es sind Staubsauger bekannt, bei denen der Staubsammelraum, in welchen der Staubbeutel eingesetzt wird, an seiner Ober­seite durch einen Deckel abgedichtet ist, der als Zubehör­schale zur Aufnahme von Zubehörteilen ausgebildet ist. Diese Zubehörschale bildet den Boden eines Zubehörraumes, der sei­nerseits an der Oberseite durch einen Gehäusedeckel des Staubsaugers verschließbar ist. Der Gehäusedeckel und die Zu­behörschale stehen über eine Rasteinrichtung miteinander in Verbindung, so daß - wenn sich der Staubsauger nicht im Be­trieb befindet - durch Anheben des äußeren Deckels gleichzei­tig die Zubehörschale mitangehoben wird und dadurch der Staubsammelraum zum Einsetzen oder entnehmen des Staubbeutels geöffnet wird. Wenn sich dagegen der Staubsauger im Betrieb befindet und der äußere Gehäusedeckel angehoben wird, dann löst sich die Rasteinrichtung zwischen dem äußeren Gehäuse­deckel und der Zubehörschale, da diese durch den im Staubsam­melraum gebildeten Unterdruck dichtend gegen eine auf der Oberseite entsprechender Gehäusewände angeordnete Dichtung gesaugt wird. Die Federkraft der Rasteinrichtung ist derart dimensioniert, daß die auf die Zubehörschale ausgeübte Saug­kraft in jedem Betriebszustand des Motors ausreichend ist, um die Rasteinrichtung zu lösen, falls der äußere Gehäusedeckel während des Betriebes des Staubsaugers angehoben wird.Vacuum cleaners are known in which the dust collecting space in which the dust bag is used is sealed on its upper side by a cover which is designed as an accessory tray for receiving accessories. This accessory tray forms the bottom of an accessory room, which in turn can be closed at the top by a housing cover of the vacuum cleaner. The housing cover and the accessory tray are connected to each other via a latching device, so that - when the vacuum cleaner is not in operation - the accessory tray is lifted at the same time by lifting the outer cover, thereby opening the dust collecting space for inserting or removing the dust bag. If, on the other hand, the vacuum cleaner is in operation and the outer housing cover is lifted, then the latching device between the outer housing cover and the accessory shell is released, since this is sucked sealingly against a seal arranged on the top of corresponding housing walls by the vacuum created in the dust collecting space. The spring force of the locking device is dimensioned such that the suction force exerted on the accessory shell is sufficient in any operating state of the engine to release the locking device if the outer housing cover is raised during the operation of the vacuum cleaner.

Es hat sich nun als zweckmäßig herausgestellt, die Zubehör­schale nicht nur durch den im Staubsammelraum herschenden Un­terdruck zu sichern, sondern zusätzlich durch einen Ver­schluß, der auch im betriebslosen Zustand des Staubsaugers einen sicheren Halt der Zubehörschale gewährleistet, damit Zubehörteile bereits vor dem Staubsaugen aus dem Zubehörraum entnommen bzw. hineingelegt werden können. Ein solcher Ver­schluß soll einfach gestaltet sein, von einer von den zu ver­schließenden Bauteilen des Staubsaugers möglichst unabhängi­gen Vorrichtung gebildet sein, die sich leicht montieren bzw. demontieren läßt, und einen kostengünstigen sicheren Ver­schluß gewährleistet.It has now proven to be expedient not only to secure the accessory tray by means of the negative pressure prevailing in the dust collecting space, but also by means of a closure, which also operates when the vacuum cleaner is inoperative A secure hold of the accessory tray is guaranteed, so that accessories can be removed from the accessory room before being vacuumed. Such a closure should be simple, be formed by a device that is as independent as possible of the components of the vacuum cleaner to be closed, which is easy to assemble or disassemble, and which ensures an inexpensive, secure closure.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Verschluß ein an dem schwenkbar gelagerten Bauteil befe­stigtes Federelement aufweist, welches in seiner Schließstel­lung einen angrenzenden Wandabschnitt federnd hintergreift und zum Öffnen mittels Deformation entriegelbar ist. Bei dem schwenkbar gelagerten Bauteil kann es sich um die den Staub­sammelraum des Staubsaugers abdichtende Zubehörschale han­deln, an deren Randwulst das Federelement befestigt ist, wäh­rend der angrenzende Wandabschnitt die Gehäusewand des Staub­saugers bilden kann, welche von dem Federelement unter- oder hintergriffen wird. Hierdurch wird gewährleistet, daß die Zu­behörschale auch in betriebslosem Zustand des Staubsaugers sicher in der Schließstellung gehalten wird, so daß der äußere Gehäusedeckel zum Entnehmen bzw. Einlegen von Zubehör­teilen geöffnet werden kann, ohne daß sich gleichzeitig die Zubehörschale aufgrund der zwischen dem äußeren Deckel und der Zubehörschale angeordneten Rasteinrichtung mitöffnet. Während des Betriebes sorgt der sich im Staubsammelraum aus­bildende Unterdruck dafür, daß die Zubehörschale umlaufend dichtend gegen entsprechende Gehäusewände anliegt, so daß keine Falschluft an der Zubehörschale vorbei in den Staubsam­melraum eintreten kann. An der zur Gehäusewand weisenden Seite besitzt das Federelement einen Schenkel, der in einem Abstand zur Frontseite der Zubehörschale angeordnet ist, und dieser Schenkel besitzt wenigstens zwei Nocken, die einen Ab­schnitt der Gehäusewand rastend untergreifen. Der Schenkel ist dabei einer Eingriffsöffnung in der Gehäusewand des Staubsaugers zugeordnet und ragt in diese hinein. Durch Ein­ drücken des Schenkels deformiert sich dieser in Richtung zur Frontseite der Zubehörschalenwand, so daß die Nocken außer Eingriff kommen und der Verschluß ausrastet, wodurch ein An­heben der Zubehörschale ermöglicht wird.This object is achieved according to the invention in that the closure has a spring element fastened to the pivotably mounted component, which in its closed position engages behind an adjacent wall section and can be unlocked for opening by means of deformation. The pivotally mounted component can be the accessory shell which seals the dust collection space of the vacuum cleaner, to the edge bead of which the spring element is fastened, while the adjoining wall section can form the housing wall of the vacuum cleaner, which the spring element engages under or behind. This ensures that the accessory tray is held securely in the closed position even when the vacuum cleaner is inoperative, so that the outer housing cover can be opened for removing or inserting accessory parts without the accessory tray being opened due to the between the outer cover and the Accessory tray arranged locking device opened. During operation, the negative pressure that forms in the dust collecting space ensures that the accessory shell is sealingly seated against corresponding housing walls, so that no false air can enter the dust collecting space past the accessory shell. On the side facing the housing wall, the spring element has a leg which is arranged at a distance from the front of the accessory shell, and this leg has at least two cams which engage under a section of the housing wall in a latching manner. The leg is assigned to an engagement opening in the housing wall of the vacuum cleaner and projects into this. Through a pressing the leg deforms it towards the front of the accessory tray wall, so that the cams disengage and the latch disengages, thereby allowing the accessory tray to be lifted.

In vorteilhafter Weise ist das Federelement als einstückiges Bauteil ausgebildet, welches in seinem Längsschnitt in etwa u-förmig geformt ist und den Randwulst der Zubehörschale übergreift. Das Federelement wird mittels zweier an der Ober­seite des Randwulstes angeformter Niederhalter gehalten, die das Federelement untergreift. Diese Niederhalter sind diago­nal versetzt zueinander gegenüberliegend angeordnet, d.h. daß ein Niederhalter im Bereich der äußeren Stirnwand des Rand­wulstes und der andere Niederhalter im Bereich der inneren Stirnwand des Randwulstes auf dessen Oberseite angeordnet ist. Das Federelement stützt sich mit seinem der Innenseite der Zubehörschale zugeordneten Schenkel an einer Nocke der Zubehörschale ab, so daß diese Nocke bei Einwirken einer Druckkraft auf den äußeren Schenkel des Federelementes als Widerlager dient. Zur Erleichterung der Montage bzw. Demon­tage sind der an der Oberseite des Randwulstes verlaufende Steg und der innere Schenkel des Federelementes in ihrer Ab­wicklung v-förmig ausgespart, wobei die Aussparung symme­trisch zur Längsmittelebene des Federelementes und mit der Spitze des V's im Bereich des äußeren Schenkels angeordnet ist. Dadurch lassen sich die Seitenabschnitte des inneren Schenkels des Federelementes elastisch zusammendrücken, so daß diese problemlos unter die Niederhalter gelangen und beim Loslassen mit diesen verrastet sind.In an advantageous manner, the spring element is designed as a one-piece component, which is shaped approximately U-shaped in its longitudinal section and engages over the edge bead of the accessory shell. The spring element is held by means of two hold-downs formed on the top of the edge bead, which hold the spring element underneath. These hold-down devices are arranged diagonally opposite one another, i.e. that a hold-down device is arranged in the area of the outer end wall of the edge bead and the other hold-down device is arranged in the area of the inner end wall of the edge bead on the upper side thereof. The spring element is supported with its leg assigned to the inside of the accessory shell on a cam of the accessory shell, so that this cam serves as an abutment when a pressure force acts on the outer leg of the spring element. To facilitate assembly and disassembly, the web running on the top of the edge bead and the inner leg of the spring element are recessed in a V-shape, the recess being arranged symmetrically to the longitudinal center plane of the spring element and with the tip of the V in the area of the outer leg is. As a result, the side sections of the inner leg of the spring element can be elastically compressed, so that they can easily get under the hold-down devices and are locked with them when released.

Weitere Merkmale, Vorteile und Einzelheiten der Erfindung er­geben sich aus der nachfolgenden Beschreibung eines bevorzug­ten Ausführungsbeispiels anhand der Zeichnung. Darin zeigen:

  • Fig. 1 eine Längsschnittansicht durch den erfindungsge­mäßen Verschluß und der damit verschlossenen Bau­teile eines Staubsaugers;
  • Fig. 2 eine schematische Draufsicht, wobei der obere Gehäusedeckel weggelassen ist;
  • Fig. 3 eine Ansicht des erfindungsgemäßen Federelementes in Richtung des Pfeiles A, und
  • Fig. 4 eine Rückseitenansicht des erfindungsgemäßen Federelementes entgegen der Richtung des Pfeiles A.
Further features, advantages and details of the invention result from the following description of a preferred exemplary embodiment with reference to the drawing. In it show:
  • Figure 1 is a longitudinal sectional view through the closure according to the invention and the components of a vacuum cleaner closed with it.
  • Fig. 2 is a schematic plan view with the upper housing cover omitted;
  • Fig. 3 is a view of the spring element according to the invention in the direction of arrow A, and
  • 4 is a rear view of the spring element according to the invention against the direction of arrow A.

Der in der Fig. 1 in schematischer Weise im Längsschnitt dar­gestellte Verschluß 1 besteht aus einem einstückig ausgebil­deten Federelement 2, welches die Teile 3, nämlich die Zube­hörschale, und 4, nämlich das Gehäuse eines Staubsaugers, lösbar miteinander verbindet.The closure 1 shown schematically in longitudinal section in FIG. 1 consists of a one-piece spring element 2, which releasably connects the parts 3, namely the accessory shell, and 4, namely the housing of a vacuum cleaner.

Wie aus der Figur ferner zu entnehmen ist, ist auf der Gehäu­sewand 4 des Staubsaugers eine umlaufende Dichtung 5 angeord­net, auf welcher die Zubehörschale 3 in ihrem Schließzustand aufliegt und gegen welche die Zubehörschale durch den sich im Staubsammelraum 6 bildenden Unterdruck während des Betriebes des Staubsaugers gesaugt wird. Die Zubehörschale 3 dient als Boden für einen Zubehörraum 7, der nach oben durch den Gehäu­sedeckel 8 des Staubsaugers verschließbar ist. An der Vorder­seite des Staubsaugergehäuses 4 befindet sich eine Eingriffs­öffnung 9.As can also be seen from the figure, a circumferential seal 5 is arranged on the housing wall 4 of the vacuum cleaner, on which the accessory shell 3 rests in its closed state and against which the accessory shell is sucked by the negative pressure which forms in the dust collecting space 6 during operation of the vacuum cleaner becomes. The accessory tray 3 serves as the floor for an accessory space 7, which can be closed at the top by the housing cover 8 of the vacuum cleaner. There is an engagement opening 9 on the front of the vacuum cleaner housing 4.

Aus dem Längsschnitt durch das Federelement 2 in Fig. l ist zu erkennen, daß dieses im wesentlichen u-förmig ausgebildet ist und einen äußeren Schenkel 10, einen Steg 11 und einen inneren Schenkel 12 aufweist. Das Federelement 2 übergreift einen Randwulst 13 der Zubehörschale 3 und ist derart dimen­sioniert, daß zwischen dem äußeren Schenkel 10 und der Front­seite des Randwulstes 13 ein Abstand a vorgesehen ist, wenn sich der innere Schenkel 12 an einer Nocke 14 der Zubehör­schale 3 abstützt.From the longitudinal section through the spring element 2 in FIG. 1 it can be seen that it is essentially U-shaped and has an outer leg 10, a web 11 and an inner leg 12. The spring element 2 engages over an edge bead 13 of the accessory shell 3 and is dimensioned such that a distance a is provided between the outer leg 10 and the front of the edge bead 13 if the inner leg 12 is supported on a cam 14 of the accessory shell 3.

An dem äußeren Schenkel 10 ist ein Griffteil 15 angeformt, welches in die Eingriffsöffnung 9 des Gehäuses 4 hineinragt. Zwischen dem Griffteil 15 und dem äußeren Schenkel 10 ist eine Versteifungsrippe 16 vorgesehen.A grip part 15 is formed on the outer leg 10 and protrudes into the engagement opening 9 of the housing 4. A stiffening rib 16 is provided between the handle part 15 and the outer leg 10.

Das Federelement 2 wird auf dem Randwulst 13 mit Hilfe von zwei Niederhaltern 17, 18 gehalten, die diagonal versetzt zu­einander angeordnet sind, wobei der Niederhalter 17 dem äuße­ren Rand des Randwulstes und der Niederhalter 18 dem inneren Rand des Randwulstes 13 beispielsweise zugeordnet sind. Aus der Fig. 2 ist zu entnehmen, daß der Steg 11 und der innere Schenkel 12 eine v-förmige Aussparung 19 aufweisen, wobei die Aussparung symmetrisch zur Längsmittelebene des Federelemen­tes 2 und mit der Spitze im Bereich des äußeren Schenkels 10 angeordnet ist. Durch diese Aussparung wird es ermöglicht, daß die beiden Teile des inneren Schenkels 12 zum Zwecke der Montage des Federelementes leicht zusammengedrückt werden können, um unter den Niederhaltern 17, 18 eingerastet zu wer­den.The spring element 2 is held on the edge bead 13 with the aid of two hold-down devices 17, 18 which are arranged diagonally offset from one another, the hold-down device 17 being assigned to the outer edge of the edge bead and the hold-down device 18 to the inner edge of the edge bead 13, for example. From Fig. 2 it can be seen that the web 11 and the inner leg 12 have a V-shaped recess 19, the recess being arranged symmetrically to the longitudinal center plane of the spring element 2 and with the tip in the region of the outer leg 10. This recess makes it possible for the two parts of the inner leg 12 to be compressed slightly for the purpose of assembling the spring element in order to be latched under the hold-down devices 17, 18.

Die Figuren 2 und 3 lassen ferner erkennen, daß am unteren vorderen Ende des äußeren Schenkels 10 Nocken 20, 21 ange­formt sind, welche entsprechende Gehäuseabschnitte 22, 23 un­tergreifen, wenn sich das Federelement in seiner Schließstel­lung befindet.Figures 2 and 3 also show that 10 cams 20, 21 are formed on the lower front end of the outer leg, which engage under corresponding housing sections 22, 23 when the spring element is in its closed position.

Wird nun der erfindungsgemäße Verschluß in Richtung des Pfei­les F betätigt, dann verschieben sich der Griffteil 10 und damit das Federelement 2 nach rechts, so daß die Schließ­nocken 20, 21 außer Eingriff mit den seitlichen Gehäusewan­dungen des Gehäuseoberteiles kommen und der Verschluß ent­rastet wird. Nun kann die gesamte Zubehörschale 3 einschließ­lich des Gehäusedeckels 8 nach oben angehoben werden, so daß der Staubsammelraum 6 für das Einsetzen oder Entnehmen eines Staubbeutels geöffnet wird. Bei der Einwirkung der Kraft F wird der äußere Schenkel 10 nach innen gebogen, wobei das Biegemoment durch die Niederhalter 17 und 18 und die horizon­tale Kraftkomponente der Kraft F durch die Nocke 14 der Zube­hörschale 3 aufgenommen werden, gegen welche der innere Schenkel 12 anliegt. Die vertikale Kraftkomponente der Kraft F wird durch die Niederhalter und durch den inneren Schenkel 12 aufgenommen, der gegen den Boden der Zubehörschale 3 an­liegt.If the closure according to the invention is now actuated in the direction of arrow F, then the handle part 10 and thus the spring element 2 shift to the right, so that the locking cams 20, 21 come out of engagement with the lateral housing walls of the upper housing part and the closure is unlocked. Now the entire accessory tray 3 including the housing cover 8 can be lifted upwards, so that the dust collecting space 6 for inserting or removing one Dust bag is opened. When the force F acts, the outer leg 10 is bent inward, the bending moment being absorbed by the hold-down devices 17 and 18 and the horizontal force component of the force F by the cam 14 of the accessory shell 3 against which the inner leg 12 bears. The vertical force component of the force F is absorbed by the hold-down device and by the inner leg 12, which bears against the bottom of the accessory shell 3.

Die diagonale Anordnung der Niederhalter 17 und 18 auf gegen­überliegenden Seiten des Federelementes 2 hat den besonderen Zweck, daß der Niederhalter 17 bei der Montage des Verschlus­ses unterfahren werden kann, während der Niederhalter 18 in einem Bereich des Federschenkels 12 angeordnet ist, in wel­chem der ausgesparte Schenkelteil den größten Federweg aus­führen kann, so daß dadurch die Montage wesentlich erleich­tert wird.The diagonal arrangement of the hold-down device 17 and 18 on opposite sides of the spring element 2 has the special purpose that the hold-down device 17 can be passed under during assembly of the closure, while the hold-down device 18 is arranged in an area of the spring leg 12 in which the recessed leg part can perform the largest travel, so that the assembly is much easier.
