Description

Die Erfindung betrifft eine Öffnungsmechanik zur druckfederunterstützten Betätigung eines an einer Wand oder einem Gehäuse zwischen einer Öffnungsstellung und einer Verschlußstellung schwenkbar angelenkten Flügels gemäß dem Oberbegriff des Anspruchs 1.The invention relates to an opening mechanism for actuating a spring, which is supported by a compression spring, and is pivotably hinged to a wall or a housing between an open position and a closed position, according to the preamble of claim 1.

Die Verwendung einer Öffnungsmechanik dieser Art ist bei Pkw-Anhängern mit einem Kastenaufbau üblich. Zwischen dem Gehäuse des Aufbaues und dem Deckel ist dort eine Gasdruckfeder zur Unterstützung der Öffnungsstellung des Deckels angeordnet. Derartige Systeme sind auch bei Kofferraumdeckel oder Verschlußklappen von Kombi- oder Fließheckwagen bekannt.The use of an opening mechanism of this type is common for car trailers with a box body. A gas pressure spring is arranged there to support the open position of the cover between the housing of the structure and the cover. Systems of this type are also known for trunk lids or hatchbacks of station wagons or hatchbacks.

Der Nachteil dieser Systeme liegt darin, daß bei geschlossenem Deckel die Kraft der Druckfeder zwischen Gehäuse bzw. Chassis und Deckel wirkt. Die Kraft führt bei senkrechter Lage der Druckfeder relativ zum Deckel zu einem Abheben des Deckels von der Gehäuseöffnung und bei mehr oder weniger paralleler Lage der Druckfeder relativ zum Deckel zu einem seitlichen Versetzen des Deckels. In beiden Fällen werden die Scharniere zur Anlenkung des Deckels am Gehäuse und eventuell die Verschlußmechanik zum Fixieren des Deckels in der Verschlußstellung mechanisch belastet. Um einen dichten Abschluß zwischen Gehäuse und Deckel zu erreichen, sind daher großdimensionierte Scharniere und Verschlußmechanismen erforderlich, wobei deren Langzeitstabilität oftmals nachläßt, was wiederum Undichtigkeiten an der Kontaktstelle von Gehäuse und Deckel zur Folge hat.The disadvantage of these systems is that when the cover is closed, the force of the compression spring acts between the housing or the chassis and the cover. The force leads to the cover being lifted from the housing opening when the compression spring is in a vertical position relative to the cover and to a lateral displacement of the cover when the compression spring is in a more or less parallel position relative to the cover. In both cases, the hinges for hinging the cover to the housing and possibly the locking mechanism for fixing the cover in the closed position are mechanically loaded. In order to achieve a tight seal between the housing and the cover, large-sized hinges and locking mechanisms are required, and their long-term stability often deteriorates, which in turn leads to leaks at the contact point between the housing and the cover.

Aus der DE - A-25 09 066 ist eine Öffnungsmechanik für Frontklappen von Dunstabzugshauben bekannt, bei der an einer Klapptür ein rechtwinklig starrer Hebel als erster Hebel angeordnet ist, der über einen zweiten, beweglichen Hebel mit einem dritten, drehbar am Gehäuse gelagerten Hebel verbunden ist. Die Hebel sind im Querschnitt U-förmig ausgebildet. Eine Zugfeder, die am Gehäuse gelagert und am Verbindungspunkt zwischen dem dritten und dem zweiten Hebel eingehängt ist, dient als Gewichtsausgleichselement. Die Ausbildung und Anordnung der drei Hebel und einer Zugfeder soll bewirken, daß ohne zusätzliche Bremseinrichtung die Klapptür in jeder Öffnungsstellung fixierbar ist, indem das beim Aufstellen der Klapptür immer größer werdende Rückstelldrehmoment durch die Hebel kompensiert wird. Die Öffnungsmechanik, die sich über die gesamte Tiefe des Gehäuses erstreckt, ist wegen des Raumbedarfs nur bedingt bei PKW-Anhängern mit einem Kastenaufbau, bei Kofferraumdeckeln oder Verschlußklappen von Kombi- oder Fließheckwagen einzusetzen.From DE-A-25 09 066 an opening mechanism for front flaps of extractor hoods is known, in which a right-angled rigid lever is arranged as the first lever on a folding door, which lever is connected via a second, movable lever to a third lever rotatably mounted on the housing is. The levers are U-shaped in cross section. A tension spring, which is mounted on the housing and suspended at the connection point between the third and the second lever, serves as a weight compensation element. The design and arrangement of the three levers and a tension spring is intended to ensure that the flap door can be fixed in any open position without an additional braking device, by compensating for the restoring torque, which increases when the flap door is opened, by the levers. The opening mechanism, which extends over the entire depth of the housing, can only be used to a limited extent in the case of car trailers with a box body, in trunk lids or flaps of combi or hatchback cars due to the space requirement.

Der Erfindung liegt die Aufgabe zugrunde, eine Öffnungsmechanik zu schaffen, die einen guten Abschluß zwischen einem Flügel, insbesondere einem Deckel, und einer Wand oder einem Gehäuse mit einem besonders geringen technischen Aufwand ermöglicht.The invention has for its object to provide an opening mechanism that enables a good seal between a wing, in particular a lid, and a wall or a housing with a particularly low technical effort.

Erfindungsgemäß wird die Aufgabe bei einer Öffnungsmechanik zur druckfederunterstützten Betätigung eines an einer Wand oder an einem Gehäuse zwischen einer Öffnungsstellung und einer Verschlußstellung schwenkbar angelenkten Flügels, insbesondere eines Deckels, mit einer Druckfeder, die zwischen einem ersten Lagerpunkt am Deckel oder Gehäuse und einem Verbindungspunkt eines ersten und zweiten Hebelarms gelagert ist, wobei das freie Ende des ersten Hebelsarm in einem zweiten Lagerpunkt am Deckel oder Gehäuse angelenkt ist, dadurch gelöst, daß in Verschlußstellung der Verbindungspunkt und somit auch die Druckfeder im wesentlichen axial zwischen dem ersten und zweiten Lagerpunkt mit Krafteinwirkung der Druckfeder im wesentlich zwischen den zwei Lagerpunkten angeordnet ist. Das freie Ende des zweiten Hebelarms ist in einem dritten Lagerpunkt gelagert, welcher am Gehäuse angeordnet ist, wenn der erste und zweite Lagerpunkt am Deckel gelagert sind. Wenn der erste und zweite Lagerpunkt jedoch am Gehäuse angeordnet sind, ist der zweite Hebelarm in einem am Deckel angeordneten dritten Lagerpunkt gelagert.According to the invention, the object is achieved in an opening mechanism for actuating a spring with pressure-assisted actuation of a wing which is pivotably articulated on a wall or on a housing between an open position and a closed position, in particular a cover, with a pressure spring which is mounted between a first bearing point on the cover or housing and a connection point of a first and second lever arm, the free end of the first lever arm being articulated in a second bearing point on the cover or housing, in that in the closed position the connection point and thus also the compression spring is arranged substantially axially between the first and second bearing points with the force of the compression spring substantially between the two bearing points. The free end of the second lever arm is mounted in a third bearing point which is arranged on the housing when the first and second bearing points are mounted on the cover. However, if the first and second bearing points are arranged on the housing, the second lever arm is mounted in a third bearing point arranged on the cover.

Die Druckfeder ist somit über den ersten Hebelarm an zwei Lagerpunkten am Deckel oder am Gehäuse befestigt. In Verschlußstellung liegen der erste Hebelarm und die Druckfeder im wesentlichen uniaxial zwischen diesen Lagerpunkten, wodurch die Federkraft der Druckfeder lediglich auf diese beiden Lagerpunkte wirkt. Beim Öffnen des Deckels wird die Druckfeder durch den zwischen dem Verbindungspunkt vom ersten Hebelarm und Druckfeder und dem Gehäuse oder Deckel befindlichen zweiten Hebelarm ausgelenkt. Der erste Hebelarm und die Druckfeder liegen jetzt nicht mehr uniaxial zwischen den beiden Lagerpunkten, sondern mit zunehmender Auslenkung der Druckfeder wirkt diese zunehmend in senkrechter Richtung zur Verbindungslinie zwischen den beiden ersten Lagerpunkten. Diese senkrecht wirkende Komponente kann durch den zweiten Hebelarm z.B. auf das Gehäuse zur Unterstützung der Öffnungsbewegung und/oder der Öffnungsstellung des Deckels herangezogen werden.The compression spring is thus attached via the first lever arm to two bearing points on the cover or on the housing. In the closed position, the first lever arm and the compression spring lie essentially uniaxially between these bearing points, as a result of which the spring force of the compression spring only acts on these two bearing points. When the cover is opened, the compression spring is deflected by the second lever arm located between the connection point between the first lever arm and the compression spring and the housing or cover. The first lever arm and the compression spring are no longer uniaxially between the two bearing points, but with increasing deflection of the compression spring, the spring acts increasingly in a direction perpendicular to the connecting line between the first two bearing points. This vertically acting component can e.g. be used on the housing to support the opening movement and / or the opening position of the cover.

Die Scharniere zur Befestigung des Deckels oder der Aufwand zum Abdichten der Verbindung zwischen Gehäuse und Deckel können klein gehalten werden, weil in Verschlußstellung des Deckels durch die Druckfeder keine Krafteinleitung zwischen Deckel und Gehäuse erfolgt.The hinges for attaching the cover or the effort for sealing the connection between the housing and the cover can be kept small, because in the closed position of the cover, no force is introduced between the cover and the housing by the compression spring.

Um eine symmetrische Krafteinleitung auf den Deckel in Öffnungsstellung zu erreichen, können derartige Öffnungsmechanismen beidseitig des Deckels angeordnet werden, wie es beim Automobilbau zum Öffnen schwerer, großer Fließheckklappen bekannt ist. Als Druckfeder läßt sich eine Gasdruckfeder gängigen Typs verwenden, wobei deren Größe und Federkraft den Erfordernissen anzupassen ist.In order to achieve a symmetrical introduction of force onto the cover in the open position, such opening mechanisms can be arranged on both sides of the cover, as is known in automobile construction for opening heavy, large hatchbacks. A gas pressure spring of the common type can be used as the compression spring, the size and spring force of which must be adapted to the requirements.

Besonders vorteilhaft läßt sich der erfindungsgemäße Öffnungsmechanismus zur Betätigung des Deckels von Pkw-Anhängern, im Automobilbau zum Öffnen von Deckeln, Klappen und Türen und auch zur Betätigung der Deckel von größeren Behältern oder Containern verwenden.The opening mechanism according to the invention can be used particularly advantageously for actuating the lid of car trailers, in automobile construction for opening lids, flaps and doors and also for actuating the lid of larger containers.

Liegen die Gehäusewände im Bereich der durch den Deckel zu verschließenden Öffnung im wesentlichen parallel zum Deckel in Verschlußstellung, so kann der Lagerbolzen für die Anlenkung des Hebelmechanismus am Gehäuse an einem senkrecht von der Gehäusewand abstehenden Lagerarm gehalten sein.If the housing walls lie in the area of the opening to be closed by the cover essentially parallel to the cover in the closed position, the bearing pin for the articulation of the lever mechanism on the housing can be held on a bearing arm which projects vertically from the housing wall.

Neben einem Einsatz im Automobilbereich eignet sich die Öffnungsmechanik auch für die Verwendung bei Oberlichten, Fenstern und Türen in Häusern und Hallen.In addition to use in the automotive sector, the opening mechanism is also suitable for use with skylights, windows and doors in houses and halls.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.Further advantageous embodiments of the invention are described in the subclaims.

Die Erfindung wird beispielsweise anhand der schematischen Zeichnung beschrieben. Es zeigen:'

  • Fig. 1 die Seitenansicht eines Behälters mit einem in Öffnungsstellung befindlichen gasdruckfederunterstützten Deckel und
  • Fig. 2 die Ansicht aus Fig. 1 mit dem Deckel in Verschlußstellung.
The invention is described for example with reference to the schematic drawing. Show it:'
  • Fig. 1 is a side view of a container with a gas spring-assisted lid in the open position and
  • Fig. 2 shows the view from Fig. 1 with the lid in the closed position.

Fig. 1 und 2 zeigen einen Behälter 10 als Aufsatz für einen Pkw-Anhänger. Der Behälter 10 hat ein kastenförmiges Gehäuse 12, dessen obere Abschlußfläche durch einen Deckel 14 verschließbar ist, der mit Scharnieren 15 an dem Gehäuse schwenkbar angelenkt ist. Die Ränder des Deckels 14 sind zum Gehäuse 12 hin umgebogen und bilden so seitliche Abschlußwände 16, die in Verschlußstellung des Deckels 14 an den Seitenwänden des Gehäuses 12 anliegen. Die dem Betrachter zugewandte Abschlußwand 16 des Deckels 14 trägt an ihrer dem Gehäuseinneren zugewandten Innenseite eine aus Metall bestehende Grundplatte 18, die an ihren beiden Längsenden jeweils einen Lagerbolzen 20,24 aufweist. Am vorderen Lagerbolzen 20 ist das eine Ende einer Gasdruckfeder 22 und die Bolzenachse schwenkbar angelenkt. Der hintere Lagerbolzen 24 dient zur Aufnahme eines ersten Hebelarms 26, der mit dem anderen Ende der Gasdruckfeder 22 schwenkbar verbunden ist. Der Abstand der beiden Lagerbolzen 20,24 voneinander entspricht zumindest der Länge des ersten Hebelarms 26 und der Länge der Gasdruckfeder 22 in zusammengedrückter Stellung (Fig. 2). An dem Verbindungspunkt 28 zwischen Gasdruckfeder 22 und erstem Hebelarm 26 greift ein zweiter Hebelarm 30 an, der an einem am Gehäuse 12 angeordneten unteren Lagerbolzen 32 schwenkbar gelagert ist. Der untere Lagerbolzen 32 ist auf einer Befestigungsplatte 34 montiert, die mit dem Gehäuse 12 z.B. durch Schrauben oder Nieten verbunden ist.1 and 2 show a container 10 as an attachment for a car trailer. The container 10 has a box-shaped housing 12, the upper end surface of which can be closed by a cover 14 which is hinged to the housing with hinges 15. The edges of the cover 14 are bent towards the housing 12 and thus form lateral end walls 16 which rest in the closed position of the cover 14 on the side walls of the housing 12. The end wall facing the viewer 16 of the cover 14 carries on its inside facing the housing interior a metal base plate 18, which has a bearing pin 20, 24 on each of its two longitudinal ends. On the front bearing pin 20, one end of a gas pressure spring 22 and the pin axis is pivoted. The rear bearing pin 24 serves to receive a first lever arm 26 which is pivotally connected to the other end of the gas pressure spring 22. The distance between the two bearing pins 20, 24 corresponds to at least the length of the first lever arm 26 and the length of the gas pressure spring 22 in the compressed position (FIG. 2). At the connection point 28 between the gas pressure spring 22 and the first lever arm 26, a second lever arm 30 engages, which is pivotably mounted on a lower bearing pin 32 arranged on the housing 12. The lower bearing pin 32 is mounted on a mounting plate 34 which is connected to the housing 12, for example by screws or rivets.

Nachfolgend wird die Funktionsweise der die zwei Hebelarme 26, 30 und die Gasdruckfeder 22 enthaltenden Öffnungsmechanik beschrieben.The mode of operation of the opening mechanism containing the two lever arms 26, 30 and the gas pressure spring 22 is described below.

In Verschlußstellung des Deckels (Fig. 2) sind der erste Hebelarm 26 und die Gasdruckfeder 22 durch den zweiten Hebelarm 30 in etwa uniaxial zwischen dem vorderen und dem hinteren Lagerbolzen 20,24 des Deckels 14 ausgerichtet, wodurch die Federkraft lediglich auf diese beiden am Deckel befindlichen Lagerbolzen 20,24 wirkt, nicht jedoch zwischen Deckel 14 und Gehäuse 12. Der Deckel 14 liegt also verspannungsfrei auf dem Gehäuse 12 auf, womit sich auch bei kleiner dimensionierten Scharnieren 15 eine gute Abdichtung zwischen Gehäuse 12 und Deckel 14 realisieren läßt.In the closed position of the cover (FIG. 2), the first lever arm 26 and the gas pressure spring 22 are aligned approximately uniaxially between the front and rear bearing bolts 20, 24 of the cover 14 by the second lever arm 30, as a result of which the spring force only acts on these two on the cover located bearing pin 20,24 acts, but not between cover 14 and housing 12. The cover 14 is thus tension-free on the housing 12, which can be achieved even with smaller-sized hinges 15, a good seal between the housing 12 and cover 14.

Beim Öffnung des Deckels (Fig. 1) wird die Gasdruckfeder 22 durch den ersten und zweiten Hebelarm 26 und 30 derart verstellt, daß die Längsachse der Gasdruckfeder 22 in etwa der Richtung des zweiten Hebelarms 30 entspricht. Die Kraft der Gasdruckfeder 22 wirkt so vornehmlich zwischen dem am Deckel 14 angeordneten vorderen Lagerbolzen 20 und dem am Gehäuse angeordneten unteren Lagerbolzen 32, wobei der Deckel 14 durch die Federkraft in seiner Öffnungsstellung gehalten wird. Derartige Öffnungsmechanismen lassen sich beiderseitig des Deckels anordnen, wenn dieser z.B. sehr groß oder sehr schwer ist.When the cover is opened (FIG. 1), the gas pressure spring 22 adjusted by the first and second lever arms 26 and 30 such that the longitudinal axis of the gas pressure spring 22 corresponds approximately to the direction of the second lever arm 30. The force of the gas pressure spring 22 thus acts primarily between the front bearing pin 20 arranged on the cover 14 and the lower bearing pin 32 arranged on the housing, the cover 14 being held in its open position by the spring force. Such opening mechanisms can be arranged on both sides of the cover if it is very large or very heavy, for example.

Die Mechanik ist auch bei Hebedächern in Pkw oder bei Oberlichten oder Hebefenstern in Dachkonstruktionen von Häusern oder Hallen einsetzbar. Bezogen auf Fig. 1 und 2 lägen dann die Wände des Wagens oder der Halle im Bereich der Abschlußwände des Deckels parallel zu dessen Ebene in Verschlußstellung. Der untere Lagerbolzen wäre in diesem Falle an einem von der Wand im wesentlichen senkrecht nach unten abstehenden Lagerarm angeordnet. Die Abschlußwände des Deckels würden in Verschlußstellung direkt auf der Wandoberfläche oder auf an der Wandoberfläche angeordneten Dichtkanten oder Leisten aufliegen.The mechanics can also be used for lifting roofs in cars or for skylights or lifting windows in roof structures of houses or halls. With reference to FIGS. 1 and 2, the walls of the carriage or the hall would then lie in the area of the end walls of the cover parallel to its plane in the closed position. In this case, the lower bearing pin would be arranged on a bearing arm projecting essentially vertically downwards from the wall. In the closed position, the end walls of the lid would rest directly on the wall surface or on sealing edges or strips arranged on the wall surface.
