Description

Die Erfindung betrifft einen Staubsauger nach dem Oberbegriff des Anspruches 1.The invention relates to a vacuum cleaner according to the preamble of claim 1.

Bei einem bekannten Staubsauger dieser Art ist das Gehäuseteil über eine Saugleitung an ein Reinigungswerkzeug des Staubsaugers und ein Gebläse angeschlossen. Der vom Sauggebläse erzeugte Saugluftstrom strömt zum Sauggebläse, nach-dem der vom Reinigungswerkzeug kommende staubhaltige Saugluftstrom das Staubfilter- und-sammelbehältnis durchströmt hat.In a known vacuum cleaner of this type, the housing part is connected to a cleaning tool of the vacuum cleaner and a blower via a suction line. The suction air flow generated by the suction fan flows to the suction fan after the dust-containing suction air flow coming from the cleaning tool has flowed through the dust filter and collection container.

In bestimmten Zeitabständen muß das Staubfilter- und-sammelbehältnis geleert oder ausgewechselt werden, wenn das Behältnis beispielsweise ein Einwegbeutel ist.The dust filter and collection container must be emptied or replaced at certain intervals, for example if the container is a disposable bag.

Da das Staubfilter- und -sammelbehältnis bei starkem Schmutzanfall häufig geleert bzw. ausgewechselt werden muß, muß auch der Deckel einfach und schnell und ohne besondere Vorsichtsmaßnahmen geöffnet und wieder geschlossen werden können. Hierzu ist der Deckel gelenkig und unlösbar am Gehäuseteil befestigt, so daß er in Offenstellung am Gehäuseteil verbleibt und nicht von diesem abgenommen und auf einer Ablagefläche abgelegt zu werden braucht. Da der Deckel aber relativ groß und schwer ist,Since the dust filter and collection container must be emptied or replaced frequently in the event of heavy dirt accumulation, the lid must also be able to be opened and closed easily and quickly and without special precautionary measures. For this purpose, the lid is articulated and permanently attached to the housing part, so that it remains in the open position on the housing part and does not need to be removed from it and placed on a storage surface. But since the lid is relatively large and heavy,

besteht die Gefahr, daß er oder sein Gelenk durch Anstoßen am Deckel oder beim Einsetzen des Behältnisses oder auch durch unsachgemäßes öffnen beschädigt oder zerstört werden. Dann muß meist der Deckel oder das Gehäuseteil ersetzt werden, was mit einem erheblichen Arbeits- und Zeitaufwand und Kosten verbunden ist.there is a risk that he or his joint may be damaged or destroyed by bumping against the lid or when inserting the container or also by improper opening. Then usually the lid or the housing part must be replaced, which is associated with a considerable amount of work and time and costs.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger dieser Art so auszubilden, daß der Deckel und das Gehäuseteil beim Anstoßen am Deckel oder beim unsachgemäßen öffnen des Deckels nichtbeschädigt oder zerstört werden können.The invention has for its object to provide a vacuum cleaner of this type so that the lid and the housing part can not be damaged or destroyed when bumping against the lid or when improperly opening the lid.

Diese Aufgabe wird bei einem Staubsauger der gattungsbildenden Art mit den kennzeichnenden Merkmalen des Anspnches 1 gelöst.This object is achieved in a vacuum cleaner of the generic type with the characterizing features of claim 1.

Infolge der erfindungsgemäßen Ausbildung wird der geöffnete Deckel bei übermäßiger Krafteinwirkung aus seiner Offenstellung in eine Freigabestellung bewegt, wobei er den auf ihn wirkenden Kräften ausweichen kann. Hierbei kann der Deckel so weit über die Offenstellung hinausbewegt werden, bis er belastungsfrei am Gehäuseteil zur AnBge kommt. Durch das Wegschwenken des Deckels ist sichergestellt, daß der Deckel oder das Gehäuseteil nichtbeschädigt werden können. Da denDeckel auch in der Freigabestellung am Gehäuseteil gehalten ist, kann er durch entgegengesetzte Bewegung einfach und schnell in seine Schließstellung zurückgeführt werden.As a result of the design according to the invention, the open lid is moved from its open position into a release position in the event of excessive force, it being able to avoid the forces acting on it. Here, the cover can be moved beyond the open position until it comes to the housing part without stress. Swiveling the cover away ensures that the cover or the housing part cannot be damaged. Since the cover is also held on the housing part in the release position, it can be quickly and easily returned to its closed position by moving it in the opposite direction.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features of the invention result from the further claims, the description and the drawings.

Fig. 1 zeigt einen Teil eines Staubsaugergehäuses 1, in dem ein Motorgehäuse untergebracht ist, das einen von einem (nicht) dargestellten) Reinigungswerkzeug des Staubsaugers kommenden Saugluftstrom über eine (nicht dargestellte) Suagleitung einem als Beutel 3 ausgebildeten Staubfilter- und -sammelbehältnis zuführt. Der Beutel 3 liegt in einem mit einem Deckel 5 verschließbaren Aufnahmeraum4 des Gehäuseteiles 1, aus dem er zum Entleeren oder, wenn er als Einwegbeutel ausgebildet ist, zum Auswechseln leicht entnommen und in den er entsprechend einfach und schnell wieder eingesetzt werden kann. Der Beutel 3 ist mit einer (nicht dargestellten) Staubluftzuführleitung verbunden. Der vom Motorgebläse 2 erzeugte Saugluftstrom durchströmt den Beutel 3, wobei der aufgenommene Schmutz und Staub in bestimmten Zeitabständen entfernt werden müssen.Fig. 1 shows a part of a vacuum cleaner housing 1, in which a motor housing is housed, one of a (not) shown) cleaning tool of the vacuum cleaner coming suction air stream via a (not shown) Suagleitung a bag 3 designed as a dust filter and collecting container. The bag 3 lies in a receptacle 4 of the housing part 1 which can be closed with a lid 5, from which it can be easily removed for emptying or, if it is designed as a disposable bag, for replacement and into which it can be reinserted simply and quickly. The bag 3 is connected to a dust air supply line (not shown). The suction air flow generated by the motor blower 2 flows through the bag 3, the dirt and dust absorbed having to be removed at certain time intervals.

Der großflächig ausgebildete Deckel 5 ist über einen Schwenkarm 6 gelenkig und unlösbar mit dem Gehäuseteil 1 verbunden. Der Schwenkarm 6 ist ein zweiarmiger, länglicher, plattenartiger Hebel. Sein einer Hebelarm 7 ist in Längsrichtung teilkreisförmig gekrümmt und mit einem etwa in halber Länge und radial zu ihm verlaufende Haltesteg 18 um eine Schwenkachse 8 schwenkbar am Gehäuseteil 1 befestigt. Am anderen, etwa gleich langen und gerade ausgebildeten Hebelarm 12 ist der Deckel 5 schwenkbar gelagert. Die zugehörige Schwenkachse 9 liegt unmittelbar benachbart zu einem konkav gekrümmten Randabschnitt 7b (Fig.2) des Hebelarmes 7. Das freie Ende 7a des Hebelarmes 7 ist durch einen dünnen Federsteg 10 gebildet, der wesentlich dünner ist als der zwischen dem Haltesteg 18 und dem Hebelarm 12 liegende: Armabschnitt 10' (Fig.2) sowie der Hebelarm 12. Die Enden 7a und 12a des Schwenkarmes6 weisen jeweils ein Rastglied 11 bzw. 13 einer Haltevorrichtung 11, 16 und 13, 14 auf, mit denen der Deckel 5 in seiner Offenstellung gemäß Fig. 2 gegenüber dem Gehäuseteil 1 verriegelt ist.The large cover 5 is articulated and non-detachably connected to the housing part 1 via a swivel arm 6. The swivel arm 6 is a two-armed, elongated, plate-like lever. One of its lever arms 7 is curved in the form of a part circle in the longitudinal direction and is fastened to the housing part 1 by means of a holding web 18 which extends approximately in half length and extends radially to it about a pivot axis 8. On the other, approximately equally long and straight lever arm 12, the cover 5 is pivotally mounted. The associated pivot axis 9 is located directly adjacent to a concavely curved edge section 7b (FIG. 2) of the lever arm 7. The free end 7a of the lever arm 7 is formed by a thin spring web 10, which is considerably thinner than that between the holding web 18 and the lever arm 12 lying: Arm section 10 '(Fig.2) and the lever arm 12. The ends 7a and 12a of the swivel arm 6 each have a locking member 11 or 13 of a holding device 11, 16 and 13, 14 with which the cover 5 in its open position 2 is locked against the housing part 1.

In der Offenstellung liegt das nockenförmige Rastglied 11 des Hebelarmes 7 in einem nutförmig ausgebildeten Rastgegenglied 16 einer Gehäusewand 17,während das schulterförmig ausgebildete Rastglied 13 des Hebelarmes 12 an einem bügelartigen Rastgegenglied 14 des Deckels 5 anliegt. Gleichzeitig stützt sich der Schwenkarm 6 mit einem Vorsprung 20 an einer Innenfläche 15 des Deckels 5 ab, wodurch der Deckel beim öffnen auf die Haltevorrichtung 13, 14 eine Gegenkraft ausübt,so daß'die Rastvorrichtung in Schließstellung und während des Öffnens nicht unbeabsichtigt gelöst wird.In the open position, the cam-shaped locking member 11 of the lever arm 7 lies in a groove-shaped locking counter-member 16 of a housing wall 17, while the shoulder-shaped locking member 13 of the lever arm 12 bears against a bow-like locking counter-member 14 of the cover 5. At the same time, the swivel arm 6 is supported with a projection 20 on an inner surface 15 of the cover 5, as a result of which the cover exerts a counterforce when opening the holding device 13, 14, so that the latching device is not unintentionally released in the closed position and during opening.

Wenn der Deckel 5 zum öffnen in Richtung des Pfeiles P in Fig. 2 geschwenkt wird, schwenkt auch der über die Haltevorrichtung 13, 14 fest mit dem Deckel 5 verbundene. Schwenkarm 6 um seine Schwenkachse 8 am Gehäuseteil 1, bis das Rastglied 11 am Ende 7a des Hebelarmes 7 in das Rastgegenglied 16 der Gehäusewand 17einrastet. Hierbei kommt der Haltesteg 18 an einem Anschlag 19 des Gehäuseteiles 1 zur Anlage, so daß der Schwenkarmricht über die Offenstellung hinaus verschwenkt werden kann. Der Deckel 5 befindet sich nun in einer annähernd senkrechten Stellung zum Gehäuseteil 1 und damit in seiner gebrauchsmäßigen Offenstellung, in der der Beutel 3 aus dem Aufnahmeraum 4 herausgenommen und anschließend wieder in diesen eingesetzt werden kann (Fig. 2).When the cover 5 is pivoted to open in the direction of the arrow P in FIG. 2, the cover 5 also pivots via the holding device 13, 14. Swivel arm 6 about its pivot axis 8 on the housing part 1 until the locking member 11 at the end 7a of the lever arm 7 snaps into the locking counter member 16 of the housing wall 17. Here, the retaining web 18 comes to rest against a stop 19 of the housing part 1, so that the swivel arm can be pivoted beyond the open position. The lid 5 is now in an approximately vertical position to the housing part 1 and thus in its open position in use, in which the bag 3 can be removed from the receiving space 4 and then reinserted into it (FIG. 2).

Beim öffnen des Deckels. 5 dient der vom Haltesteg 18 abgewandte ununterbrochene,konvex gekrümmte Randabschnitt 7c des Hebelarmes 7 als Führungsteil, mit dem der Schwenkarm 6 längs eines freien Endes 17a (Fig. 1) der Gehäusewand 17 gleitet. Dadurch ist der Deckel beim Verschwenken genau gegenüber dem Gehäuseteil 1 ausgerichtet, so daß er leichtgängig verschwenkt werden kann und eine Beschädigung der Gelenkteile einwandfrei verhindert ist.When opening the lid. 5 remote from the holding web 18 uninterrupted, convex curved edge portion 7 serves c of the lever arm 7 as a guide part to which the pivoting arm 6 along a free end 17a (FIG. 1) of the housing wall 17 slides. As a result, the lid is exactly opposite to when pivoting Housing part 1 aligned so that it can be pivoted easily and damage to the joint parts is properly prevented.

Wirken auf den Deckel 5 in seiner Offenstellung nach Fig.2, z.B. durch Anstoßen am Deckel beim Herausnehmen oder Wiedereinsetzen des Beutels 3 oder auch beim öffnen durch unsachgemäße Bedienung übermäßige Kräfte, dann wird der Deckel 5 über die Offenstellung hinaus ein eine Freigabestellung (Fig. 3) geschwenkt. Dabei wird das Rastgegenglied 14 über das Rastglied 13 hinweg gedrückt, so daß die Haltevorrichtung 13, 14 gelöst ist und der Deckel in Richtung des Pfeiles P den auf ihn wirkenden Kräften ausweichen kann. Gleichzeitig bleibt aber die Rastverbindung der Haltevorrichtung 11, 16 bestehen, da der Anschlag 19 des Gehäuseteiles 1 verhindert, Gehäuseteiles Schwenkarm 6 mitdreh sich der Schwenkarm mitdrehen kann. Infolge dieser Ausweichbewegung des Deckels 5 ist sichergestellt, daß die Krafteinwirkung auf den Deckel und damit das Gehäuseteil nicht zu einer Beschädigung oder Zerstörung dieser Teile führen kann.Act on the lid 5 in its open position according to Fig. 2, e.g. by bumping against the lid when removing or reinserting the bag 3 or when opening due to improper operation, excessive forces are applied, then the lid 5 is pivoted beyond the open position into a release position (FIG. 3). The locking counter-member 14 is pressed over the locking member 13 so that the holding device 13, 14 is released and the cover in the direction of arrow P can avoid the forces acting on it. At the same time, however, the latching connection of the holding device 11, 16 remains in place, since the stop 19 of the housing part 1 prevents the housing part from pivoting arm 6, so that the pivoting arm can also rotate. As a result of this evasive movement of the cover 5, it is ensured that the force acting on the cover and thus the housing part cannot lead to damage or destruction of these parts.

Aus der Freigabestellung kann der Deckel 5 in die Schließstellung (Fig. 1) einfach und schnell durch Verschwenken entgegen der Richtung des Pfeiles P gebracht werden. Dabei wird selbsttätig die Rastverbindung der Haltevorrichtung 13, 14 wieder hergestellt und die Rastverbindung der Haltevorrichtung 11, 16 gelöst, sodaß der Deckel nach dem Schließen ohne zusätzliche Maßnahmen erneut geöffnet werden kann.From the release position, the cover 5 can be brought into the closed position (FIG. 1) simply and quickly by pivoting against the direction of the arrow P. The locking connection of the holding device 13, 14 is automatically restored and the locking connection of the holding device 11, 16 is released, so that the lid can be opened again after closing without additional measures.

Bei der Ausführungsform nach den Fig. 4 bis 6 ist der Schwenkarm 32 einstückig mit dem Deckel 31 ausgebildet. Er ist über seine ganze Länge teilkreisförmig gekrümmt und hat jeweils gleiche Breite. Beim Verschwenken des Deckels gleitet der Schwenkarm auf einem kreissegmentförmig ausgebildeten Lagerabschnitt 34 des Gehäuseteiles 30. Zur Lagesicherung und zum leichtgängigen öffnen des Deckels 31 gegenüber dem Gehäuseteil 30 weisen der Schwenkarm 32 und der Lagerabschnitt 34 nutfederartig ineinandergreifende Führungsteile 21, 22 auf, die durch eine entsprechende Profilierung dieser Teile gebildet sind. Wie insbesondere Fig.5 zeigt, hat der Schwenkarm 32 U-förmigen Querschnitt mit rechtwinklig nach außen abgebogenen Schenkelenden 23,24 . Dagegen ist das Führungsteil 22 des Lagerabschnittes 34 durch einen im Querschnitt U-förmigen Steg gebildet, der formschlüssig in .die das zugehörige Führungsteil 21 bildende Eintiefung des Schwenkarmes 32 ragt. Zur Versteifung ist der Lagerabschnitt 34 im Bereich außerhalb seiner Auflageflächen 26, 27 für die Schenkel 23,24 des Schwenkarmes 32 stärker ausgebildet als im übrigen Bereich.In the embodiment according to FIGS. 4 to 6, the swivel arm 32 is formed in one piece with the cover 31. It is part-circularly curved over its entire length and has the same width in each case. When the cover is pivoted, the swivel arm slides on a circular segment Bearing section 34 of the housing part 30. For securing the position and for easy opening of the cover 31 relative to the housing part 30, the swivel arm 32 and the bearing section 34 have tongue and groove interlocking guide parts 21, 22 which are formed by a corresponding profiling of these parts. As shown in FIG. 5 in particular, the swivel arm 32 has a U-shaped cross section with leg ends 23, 24 bent outwards at right angles. In contrast, the guide part 22 of the bearing section 34 is formed by a cross-sectionally U-shaped web which projects positively into the recess of the swivel arm 32 forming the associated guide part 21. For stiffening, the bearing section 34 in the area outside its bearing surfaces 26, 27 for the legs 23, 24 of the swivel arm 32 is stronger than in the rest of the area.

Die Haltevorrichtun 33, 35 besteht aus eirem als federnde Rastnocke ausgebildeten Rastglied 33 des Schwenkarmes 32 und einer das Rastgegenglied 35 bildenden Rastöffnung des Lagerabschnittes 34 (Fig. 4, 6). Das Rastglied 33 liegt unmittelbar benachbart zu dem konvex gekrümmten Randabschnitt 28 und der Öffnung 21 des Schwenkarmes 32. Das Rastglied 33 hat vom freien Ende 29 des Schwenkarmes 32 einen etwa einem Viertel seiner Länge entsprechenden Abstand. Dieser ist so gewählt, daß sichergestellt ist, daß der Schwenkarm 32 und der Lagerabschnitt 34 selbst in der Freigabestellung des Deckels 31 nicht außer Eingriff kommen können, um den Deckel aus dieser Stellung einfach und schnell in die Schließstellung zürückbewegen zu können.The holding device 33, 35 consists of a locking member 33 of the swivel arm 32 designed as a resilient locking cam and a locking opening of the bearing section 34 forming the locking counter-member 35 (FIGS. 4, 6). The locking member 33 is located immediately adjacent to the convexly curved edge section 28 and the opening 21 of the swivel arm 32. The locking member 33 is at a distance corresponding to approximately a quarter of its length from the free end 29 of the swivel arm 32. This is selected so that it is ensured that the swivel arm 32 and the bearing section 34 cannot come out of engagement even in the release position of the cover 31, in order to be able to move the cover back into the closed position easily and quickly.

Das Rastgegenglied 35 liegt an dem in öffnungsrichtung (Pfeil P) vorderen Ende 39 zwischen dem verdeckten radial äußeren Randabschnitt 38 und dem Führungssteg 22. Mit der Haltevorrichtung 33,35 ist der Deckel 31 in seiner Offenstellung verriegelt und kann auch über diese zur Vermeidung einer Beschädigung in Richtung des Pfeiles P über die Offenstellung hinausbewegt werden, um einer übermäßigen Krafteinwirkung ausweichen zu können.The locking counter-member 35 lies at the front end 39 in the opening direction (arrow P) between the concealed radially outer edge section 38 and the guide web 22 Holding device 33, 35, the cover 31 is locked in its open position and can also be moved over the open position in order to avoid damage in the direction of the arrow P in order to avoid excessive force.

Wie Fig. 6 weiter zeigt, verjüngen sich die Rastglieder 33,35 in Richtung P spitzwinklig, so daß das Rastglied 33 leicht aus dem Rastgegenglied 35 heraus- bzw. in dieses hineinbewegt werden kann, um den Deckel in seine Freigabestellung bzw. beim Schließen über die Offenstellung hinweg bewegen können. Die hierzu erforderliche Kraft kann dagegen verändert werden, daß der spitze Winkel des Rastgliedes 33 bzw. des Rastgliedes 35 kleiner oder größer gewählt ist.As further shown in FIG. 6, the latching members 33, 35 taper at an acute angle in the direction P, so that the latching member 33 can be easily moved out of or into the latching counter member 35 by the lid in its release position or when closing can move the open position away. The force required for this, however, can be changed so that the acute angle of the locking member 33 or the locking member 35 is chosen to be smaller or larger.

Von diesem Staubsauger unterscheidet sich die Ausführungsform nach den Fig.7 und 8 lediglich dadurch, daß die Haltevorrichtung 45 als Schenkelfeder ausgebildet ist.The embodiment of FIGS. 7 and 8 differs from this vacuum cleaner only in that the holding device 45 is designed as a leg spring.

Der Deckel 41 ist ebenfalls einstückig mit dem teilkreisförmig, gekrümmten, scheibenförmigen Schwenkarm 42 verbunden, der auf dem widerum kreissegmentförmigen Lagerabschnitt 44 des Gehäuseteiles 40 durch nutfederartig ineinandergreifende Führungsteile 36, 37 (Fig.8) verschwenkbar geführt ist. Dadurch kann der Deckel 41 genau gegenüber dem Gehäuseteil 40 ausgerichtet und leichtgängig verschwenkt werden.The cover 41 is also integrally connected to the part-circular, curved, disc-shaped pivot arm 42 of the housing part is guided pivotably 40 by nutfederartig interengaging guide members 36, 37 (F ig.8) on the widerum circular segment-shaped bearing portion 44th As a result, the cover 41 can be aligned precisely with respect to the housing part 40 and pivoted smoothly.

Um den Deckel 41 in seiner Offenstellung zu halten und um zu vermeiden, daß der Deckel oder das Gehäuseteil 40 beschädigt oder zerstört werden, ist die Schwenkbewegung des Deckels 41 durch die Schenkelfeder 45, deren Enden in Haltelaschen 48 und 49 des Gehäuseteiles 30 und des Deckels 31 befestigt sind, begrenzt. Durch die Feder 45 ist der Deckel 41 in seiner Offenstellung federnd gehalten. Die Vorspannung der Schenkelfeder 45 ist so gewählt, daß das Deckelteil 41 selbsttätig in seine Offenstellung schwenkt. Anschläge, an welchen z.B. die beiden Schenkel 46 und 47 der Schenkelfeder 45 anliegen, begrenzen einen höchstzulässigen Öffnungswinkel 1 α der beiden Schenkel 46 und 47 (Fig.10). Der den höchstzulässigen Öffnungswinkel α begrenzende Anschlag kann z.B. als Kapsel 50 (Fig.9,10) ausgebildet sein, die die Windungen der Schenkelfeder 45 koaxial übergreift. Ein Teil der Kapselwand ist entfernt, so daß zwei Anschlagkanten 51 und 52 entstehen, an welchem die Schenkel 46 und 47 der Schenkelfeder 45 unter Einschließung des höchstzulässigen Öffnungswinkels α anlieqen.In order to keep the cover 41 in its open position and to prevent the cover or the housing part 40 from being damaged or destroyed, the pivoting movement of the cover 41 is by the leg spring 45, the ends of which are held in retaining tabs 48 and 49 of the housing part 30 and the cover 31 are limited. By the spring 45 the cover 41 is resiliently held in its open position. The bias of the leg spring 45 is selected so that the cover part 41 automatically pivots into its open position. Attacks to which for example 46 and 47 abut the two legs of the leg spring 45, defining a maximum permissible aperture angle α 1 of the two legs 46 and 47 (F ig.10). The stop limiting the maximum permissible opening angle α can be designed, for example, as a capsule 50 (FIGS. 9, 10) which coaxially engages over the turns of the leg spring 45. Part of the capsule wall is removed, so that two stop edges 51 and 52 are formed, against which the legs 46 and 47 of the leg spring 45 abut, including the maximum permissible opening angle α.

Bei einer weiteren Möglichkeit (Fig.11,12) einer Begrenzung des höchstzulässigen Öffnungswinkels α ist der Anschlag als Lasche 53 ausgebildet, welche mit öffnungen 54, 54' versehen ist, in die die Schenkel 46 und 47 der Schenkelfeder 45 ragen. Der höchstzulässige Öffnungswinkel α der beiden Schenkel 46 und 47 wird durch Anliegen dieser Schenkel an den sich auf größtem Abstand zueinander befindenden Wänden der öffnungen 54, 54' gebildet.In a further possibility (FIGS. 11, 12) of limiting the maximum permissible opening angle α, the stop is designed as a tab 53 which is provided with openings 54, 54 'into which the legs 46 and 47 of the leg spring 45 protrude. The maximum permissible opening angle α of the two legs 46 and 47 is formed by the abutment of these legs on the walls of the openings 54, 54 'which are at the greatest distance from one another.

Eine weitere Möglichkeit besteht darin, die Vorspannung der Schenkelfeder 45 so zu wählen, daß der Öffnungswinkel α der beiden Schenkel 46 und 47 in entspanntem Zustand der Schenkelfeder 45 geringer ist als der höchstzulässige Öffnungswinkel α.Another possibility is to choose the pretension of the leg spring 45 so that the opening angle α of the two legs 46 and 47 in the relaxed state of the leg spring 45 is less than the maximum permissible opening angle α.

Zur weiteren öffnung des.Deckelteiles 41 ist es dann erforderlich, den Deckel 41 von Hand weiter zu bewegen. Um eine Deformierung der Schenkelfeder 45 zu vermeiden, ist es angebracht, den höchstzulässigen Öffnungswinkel α durch z.B. die vorgenannten Anschhagelemente 50 bzw. 53 zu begrenzen. Der maximale Öffnungswinkel α ist kleiner als 180°.To open the lid part 41 further, it is then necessary to move the lid 41 further by hand. In order to avoid deformation of the leg spring 45, it is appropriate to adjust the maximum permissible opening angle α by e.g. to limit the aforementioned stop elements 50 and 53. The maximum opening angle α is less than 180 °.
