Abstract

In the cover, frame and lid are interconnected in an articulated manner along one side. One or more pneumatic springs are in each case fastened by one end to the lid and by the other end to the frame, so that the end-points of the pneumatic springs lie closer to one another when the lid is closed than when the lid is open. According to the invention, lifting the lid is to be made easier through the force from the pneumatic springs becoming effective; moreover, pneumatic springs and the articulated connection of lid and frame together make it possible for the lid to be brought into a secured erect position. <IMAGE>

Description

Die Erfindung betrifft eine Abdeckung für ein Mannloch in einem Fußboden oder für einen Schacht, die aus einem äußeren Rahmen und einem darin ruhenden Deckel besteht.The invention relates to a cover for a manhole in a floor or for a shaft, which consists of an outer frame and a cover resting therein.

Bei privaten Schwimmbädern befindet sich unmittelbar neben dem eigentlichen Schwimmbecken oftmals ein Geräteraum, in dem die Umwälzanlage, die Heizung, irgendwelche Filter oder sonstige Reinigungseinrichtungen untergebracht sind. Wegen der nur gelegentlichen Notwendigkeit des Zugangs zu diesem Raum und wegen der oftmals beengten Platzverhältnisse führt in diesen Raum keine normale Treppe, sondern in dem darüberliegenden Fußboden ist eine Abdeckung der eingangs genannten Art vorhanden, deren Deckel beseitigt werden kann und einen Zugang zu einer Leiter frei gibt. Statt eines derartigen Mannloches in dem Fußboden kann auch ein Schacht vorhanden sein, der dann zu dem entsprechenden Raum führt.In private swimming pools, there is often an equipment room right next to the actual swimming pool, in which the circulation system, the heating, any filters or other cleaning devices are housed. Because of the occasional need for access to this room and because of the often limited space, no normal staircase leads to this room, but in the floor above there is a cover of the type mentioned, the cover of which can be removed and access to a ladder free gives. Instead of such a manhole in the floor, there may also be a shaft which then leads to the corresponding room.

Während früher einfache Stahlplatten als Deckel für derartige Schächte oder Mannlöcher dienten, bestehen in heutiger Zeit die Deckel in der Regel aus Stahlwannen mit einer Bewehrung, in die Beton eingegossen und als oberer Abschluß der in dem restlichen Raum vorhandene Fußboden eingebettet ist. Infolge des sehr genauen Sitzes zwischen dem Deckel und dem Rahmen und des stufenlosen Überganges von dem Deckel zu dem restlichen Fußboden fallen derartige Abdeckungen optisch kaum noch auf. Allerdings wird diese gute optische Eingliederung einer Abdeckung in einen Fußboden durch ein sehr hohes Gewicht des Deckels erkauft, so daß oftmals eine einzige Person den Deckel zur öffnung des darunterliegenden Raumes bzw. Schachtes nicht mehr anzuheben vermag. Selbst wenn das Anheben und Aufstellen des Deckels gelingt, besteht ständig die Gefahr, daß der an einem Gegenstand angelehnte Deckel umstürzt und dabei den Fußboden oder sogar Personen beschädigt. Sicherer ist es daher, den Deckel mit zwei Personen von dem Rahmen abzuheben und flach auf den daneben befindlichen Fußboden abzulegen. Zusammenfassend kann festgestellt werden, daß die Handhabung der heute üblichen Deckel von Abdeckungen sehr umständlich und bei geringer Aufmerksamkeit auch gefährlich ist.While in the past simple steel plates served as covers for such manholes or manholes, today the covers usually consist of steel trays with reinforcement, into which concrete is poured and the flooring in the rest of the room is embedded as an upper finish. As a result of the very precise fit between the cover and the frame and the stepless transition from the cover to the rest of the floor, such covers are hardly noticeable. However, this good optical integration of a cover into a floor is paid for by the very high weight of the cover, so that often a single person is no longer able to lift the cover to open the space or shaft underneath. Even if the lid is lifted and raised, there is always the risk that the lid, which is leaning against an object, will overturn and thereby damage the floor or even people. It is therefore safer to lift the lid off the frame with two people and lay it flat on the floor next to it. In summary, it can be stated that the handling of the covers of covers which are customary today is very cumbersome and also dangerous if little attention is paid.

Es ist demnach Aufgabe der Erfindung, eine Abdeckung der eingangs genannten Art so zu verbessern, daß das öffnen von einer einzigen Person sehr leicht und ohne Gefährdung möglich ist.It is therefore an object of the invention to improve a cover of the type mentioned in such a way that it can be opened by a single person very easily and without risk.

Die Erfindung wird darin gesehen, daß der Rahmen und der Deckel entlang einer Seite gelenkig miteinander verbunden sind, und daß an dem Deckel das eine und an dem Rahmen das andere Ende einer oder mehrerer Gasfedern befestigt sind, deren beiden Endpunkte bei geschlossenem Deckel näher aneinanderliegen als bei geöffnetem Deckel.The invention is seen in that the frame and the lid are hinged together along one side, and that one and more of the gas springs are attached to the lid and the frame to the other end, the two end points of which are closer together when the lid is closed than with the lid open.

Die Erfindung begegnet den bisher vorhandenen Schwierigkeiten in zweifacher Weise. Zunächst wird mit Hilfe der Gasfedern die aufzuwendende Kraft zum Anheben des Deckels auf ein erträgliches Maß erniedrigt, so daß auch weniger kräftige Personen den Deckel anzuheben vermögen, zum anderen bewirken die gelenkige Verbindung im Zusammenwirken mit den Gasfedern eine sichere Aufstellage, die das Sichern des aufgestellten Deckels bzw. das gesonderte Beiseitelegen erspart. Insgesamt wird die Handhabung wesentlich erleichtert und sicherer. Dafür genügen in der Regel schon zwei Gasfedern, deren Einzelkraft ca. 600 N beträgt.The invention addresses the difficulties previously encountered in two ways. First, with the help of the gas springs, the force required to lift the cover is reduced to a tolerable level, so that even less powerful people can lift the cover, and on the other hand the articulated connection in cooperation with the gas springs ensures a safe installation position, which secures the set up Spared cover or the separate set aside. Overall, handling is much easier and safer. Two gas springs, the individual force of which is approximately 600 N, are usually sufficient.

Für die gelenkige Befestigung des Deckels an dem Rahmen bestehen mehrere Möglichkeiten. In der einfachsten Form sind mindestens zwei Scharniere vorhanden, deren gemeinsame Drehachse am oberen äußeren Rand des Deckels der betreffenden Seite liegt. Statt zweier Scharniere kann auch ein kräftiges Scharnierband vorhanden sein, das dann über die gesamte Breite des Deckels reicht. Wenn die gelenkige Verbindung von oben unsichtbar sein soll, bietet sich die Möglichkeit, mindestens zwei Bügelgelenke zu verwenden, deren gemeinsame Drehachse außerhalb der Sitzfläche zwischen dem Deckel und dem Rahmen liegt; als Sitzfläche sind alle Anlageflächen zwischen dem Deckel und dem Rahmen anzusehen. Allerdings kann die letztgenannte Möglichkeit Ausnehmungen innerhalb des Fußbodens bzw. innerhalb der darunterliegenden Schachtwand erfordern, um Platz für die Bügel in der Ruhelage zu schaffen.There are several options for the articulated fastening of the cover to the frame. In the simplest form there are at least two hinges, the common axis of rotation of which lies at the upper outer edge of the cover of the relevant side. Instead of two hinges, a strong hinge band can also be present, which then extends across the entire width of the lid. If the articulated connection is to be invisible from above, it is possible to use at least two stirrup joints, the common axis of rotation of which lies outside the seat between the cover and the frame; all contact surfaces between the cover and the frame are to be regarded as seats. However, the latter option may require recesses within the floor or within the shaft wall underneath in order to make room for the stirrups in the rest position.

Nachfolgend werden Ausführungsbeispiele der Erfindung, die in der Zeichnung dargestellt sind, näher erläutert; darin zeigen:

  • Fig. 1 eine schematische Querschnittsansicht durch einen mit einer erfindungsgemäßen Abdeckung versehenen Fußboden und
  • Fig. 2 eine Querschnittsansicht durch einen Schacht mit einer erfindungsgemäßen Abdeckung in einem weiteren Ausführungsbeispiel.
Exemplary embodiments of the invention which are illustrated in the drawing are explained in more detail below; show in it:
  • Fig. 1 is a schematic cross-sectional view through a floor provided with a cover according to the invention and
  • Fig. 2 is a cross-sectional view through a shaft with a cover according to the invention in a further embodiment.

In der Fig. 1 ist in einer schematischen Schnittansicht die erfindungsgemäße Abdeckung als Einbaubeispiel in einen Fußboden 1 dargestellt. In ein vorbereitetes Loch innerhalb des Fußbodens 1 ist ein Z-förmiger Rahmen 2 eingelassen und in üblicher Weise durch Anker oder dergleichen im Fußboden 1 gesichert. Der Rahmen 2 bietet sowohl eine Einfassung als auch eine Auflage für einen Deckel 3, der in der aufgestellten Lage in ausgezogenen und in der Ruhelage in gestrichelten Linien dargestellt ist. Der Deckel 3 trägt auf seiner Oberseite dieselben Ornamente bzw. dasselbe Fußbodenmaterial wie auf dem an den Rahmen 2 angrenzenden Fußboden 1 verlegt ist. Im übrigen ist er als Unterfütterung mit Beton vollgegossen; diese Einzelheiten sind jedoch für die Erfindung unwesentlich, einzig das resultierende Gewicht ist von Bedeutung.1 shows a schematic sectional view of the cover according to the invention as an example of installation in a floor 1. A Z-shaped frame 2 is let into a prepared hole within the floor 1 and secured in the floor 1 in the usual way by anchors or the like. The frame 2 offers both a border and a support for a lid 3, which is shown in the set position in extended and in the rest position in dashed lines. The lid 3 carries on its top the same ornaments or the same floor material as is laid on the floor 1 adjacent to the frame 2. For the rest, it is filled with concrete as a relining; however, these details are not essential to the invention, only the resulting weight is important.

Entlang seiner einen Seite ist der Deckel 3 mit Hilfe von mindestens zwei Scharnieren an dem Rahmen 2 gelenkig befestigt, wobei jedes Scharnier durch eine gelochte Lasche 6 und entsprechend ausgefluchtete Bohrungen innerhalb des Deckels 3 gebildet sind. Die gemeinsame Achse der Scharniere verläuft annähernd entlang des oberen äußeren Randes dieser Deckelseite, so daß eine Schwenkbewegung annähernd in die Vertikale ohne Behinderung möglich ist.Along one side, the cover 3 is articulated to the frame 2 with the aid of at least two hinges, each hinge being formed by a perforated tab 6 and correspondingly aligned bores within the cover 3. The common axis of the hinges runs approximately along the upper outer edge of this cover side, so that a pivoting movement approximately into the vertical is possible without hindrance.

Am unteren Schenkel derselben Seite des Z-Rahmens 2 sind mindestens zwei Laschen 7 angebracht, die den einen Endpunkt jeweils einer von zwei Gasfedern 8 bilden. Der andere Endpunkt besteht aus einem an der Unterseite des Deckels 3 auf jeder Seite angeordneten Auge 9, an dem jeweils die Kolbenstange der Gasfeder 8 gelenkig befestigt ist. In der dargestellten Lage sind die beiden Gasfedern 8 voll ausgefahren, mit der Folge, daß eine weitere Schwenkbewegung des Deckels 3 ausgeschlossen ist. Wegen des günstigen Angriffspunktes in dieser Aufstellage des Deckels 3 vermögen die beiden Gasfedern 8 den Deckel 3 mit sehr großen Sicherheitsreserven offen zu halten.At least two tabs 7 are attached to the lower leg of the same side of the Z-frame 2, each forming one end point of one of two gas springs 8. The other end point consists of an eye 9 arranged on the underside of the cover 3 on each side, to which the piston rod of the gas spring 8 is articulated. Are in the position shown the two gas springs 8 fully extended, with the result that a further pivoting movement of the cover 3 is excluded. Because of the favorable point of attack in this installation position of the cover 3, the two gas springs 8 are able to keep the cover 3 open with very large safety reserves.

Zum Schließen des Deckels wird dieser gegen die Wirkung der Gasfedern 8 in die Horizontale verschwenkt, wobei die Gasfedern 8 annähernd gänzlich zusammengedrückt werden. Etwa auf halbem Wege der Schwenkbewegung gewinnt das Eigengewicht des Deckels 3 die Oberhand gegenüber den Federkräften, so daß von da an der Deckel gestützt werden muß, soll er nicht auf seine Sitzfläche in dem Rahmen 2 aufschlagen. Bei geschlossenem Deckel 3 vollzieht sich das öffnen in umgekehrter Reihenfolge. Zunächst muß also der Deckel an der den Scharnieren abgewandten Seite so weit angehoben werden - selbstverständlich wirken die Gasfedern 8 dabei unterstützend - bis das Gleichgewicht zugunsten der Gasfedern 8 überschritten ist. Von dieser Schwenkstellung an wird der Deckel 3 selbsttätig bis in seine Aufstellage aufgerichtet.To close the lid, the latter is pivoted horizontally against the action of the gas springs 8, the gas springs 8 being almost completely compressed. Approximately halfway through the pivoting movement, the dead weight of the cover 3 gains the upper hand over the spring forces, so that from there on the cover must be supported if it is not to hit its seat in the frame 2. When the lid 3 is closed, the opening takes place in reverse order. First of all, the lid on the side facing away from the hinges must be raised so far - of course, the gas springs 8 have a supporting effect - until the balance in favor of the gas springs 8 has been exceeded. From this swivel position, the cover 3 is automatically erected into its installation position.

In der Fig. 2 ist die erfindungsgemäße Abdeckung in Verbindung mit einem Schacht dargestellt. Statt eines Z-Rahmens ist bei diesem Ausführungsbeispiel ein einfacherer Winkelrahmen 14 vorhanden, in dem in üblicher Weise der Deckel 3 ruht. Die Lasche 7 ist an einem Winkelstück befestigt, das seinerseits am unteren Schenkel des Winkelrahmens 14 angebracht ist. Im übrigen unterscheidet sich die Anbringung der Gasfeder 8 und des Auges 9 an dem Deckel 3 auf jeder Seite von dem Ausführungsbeispiel gemäß der Fig. 1 nicht.2, the cover according to the invention is shown in connection with a shaft. Instead of a Z frame, a simpler angle frame 14 is provided in this exemplary embodiment, in which the cover 3 rests in the usual way. The tab 7 is attached to an angle piece, which in turn is attached to the lower leg of the angle frame 14. Otherwise, the attachment of the gas spring 8 and the eye 9 to the cover 3 on each side does not differ from the exemplary embodiment according to FIG. 1.

Der wesentliche Unterschied liegt in der gelenkigen Befestigung zwischen dem Deckel 3 und dem Winkelrahmen 14. Mit Hilfe einer auf der Außenseite des Winkelrahmens 14 angebrachten Lasche 18 ist ein Bügel 16 gelagert, dessen anderes Ende unverrückbar, gegebenenfalls justierbar auf der Unterseite des Deckels 3 auf jeder Deckelseite befestigt ist. Der Bügel 16 taucht in eine Ausnehmung 15 in der darunterliegenden Mauer, die lediglich in der Breite des Bügels 16 ausgespart zu sein braucht.The main difference lies in the articulated attachment between the cover 3 and the angle frame 14. With the help of one on the outside of the angle Frame 14 attached tab 18, a bracket 16 is mounted, the other end is fixed immovably, optionally adjustable on the underside of the lid 3 on each side of the lid. The bracket 16 dips into a recess 15 in the underlying wall, which only needs to be recessed in the width of the bracket 16.

Das Ausführungsbeispiel gemäß der Fig. 2 weist den Vorteil auf, daß von der Fußbodenseite her keinerlei Scharnier zu sehen ist, es entsteht also der Eindruck, als handele es sich um einen in üblicher Weise in einen Rahmen eingelegten Deckel. Die den beiden Laschen 18 zugewandte Kante des Deckels 3 ist leicht abgeschrägt, damit die untere Kante des Deckels nicht mit der oberen Kante des Winkelrahmens 14 oder mit der Oberseite des Fußbodens in der Aufstellage kollidiert.The embodiment according to FIG. 2 has the advantage that no hinge can be seen from the floor side, so there is the impression that it is a cover inserted in the usual way into a frame. The edge of the cover 3 facing the two tabs 18 is slightly chamfered so that the lower edge of the cover does not collide with the upper edge of the angle frame 14 or with the top of the floor in the installation position.

In den dargestellten Ausführungsbeispielen sind die Laschen 7 jeweils unmittelbar oder mittelbar an den Rahmen 2 bzw. 14 befestigt. Insbesondere bei sehr kleinen Rahmen und auch bei der Nachrüstung vorhandener Abdeckungen zu erfindungsgemäßen Ausführungsformen kann es zweckmäßig sein, die Laschen 7 direkt im Mauerwerk und nicht an einer Stelle des Rahmens anzubringen. Hier kommt es auf die örtlichen Gegebenheiten an, an der Wirkung der Erfindung ändert diese gesonderte Anbringung der Laschen 7 jedoch nichts.In the illustrated embodiments, the tabs 7 are each attached directly or indirectly to the frame 2 or 14. Particularly in the case of very small frames and also when retrofitting existing covers for embodiments according to the invention, it may be expedient to attach the tabs 7 directly in the masonry and not at one point on the frame. Here it depends on the local conditions, but this separate attachment of the tabs 7 does not change the effect of the invention.

In den beiden Ausführungsbeispielen liegt der Deckel 3 jeweils direkt auf den entsprechenden Rahmenteilen auf. In üblicher Weise können hier Dichtungen vorgesehen sein, was jedoch für die Erfindung belanglos ist. Auch weist der Deckel 3 an seiner Oberseite gegebenenfalls Verschlüsse, Öffnungen oder sonstige Beschläge auf, mit deren Hilfe der Deckel positiv geschlossen bzw. leichter geöffnet werden kann.In the two exemplary embodiments, the cover 3 lies directly on the corresponding frame parts. Seals can be provided here in a conventional manner, but this is irrelevant to the invention. The lid 3 also has closures, openings or other fittings on its upper side, with the aid of which the lid can be positively closed or opened more easily.
