Description

Die Erfindung betrifft ein Abdeckelement, insbesondere einen Gullydeckel, Schachtdeckel oder ähnliche Abdeckungen für den Bereich der Abwassertechnik, mit einem Grundkörper, der eine Oberseite und eine Unterseite aufweist, wobei das Abdeckelement auf eine Auflage eines vertieften Sitzes auflegbar ist.The invention relates to a cover, in particular a manhole cover, manhole cover or similar covers for the field of wastewater technology, with a base body having an upper side and a lower side, wherein the cover is placed on a support of a recessed seat.

Abdeckelemente der vorstehend genannten Art, die sowohl durchgehend ausgebildet als auch mit Durchtrittsöffnungen, beispielsweise einem Gitterrost, versehen sein können, sind üblicherweise so in eine Oberfläche, beispielsweise eine Straßendecke oder den Boden eines Bades oder eines Kellerraumes eingefügt, dass der Grundkörper, der meist plattenförmig ausgebildet ist, in einem vertieften Sitz liegt, wobei der Grundkörper üblicherweise mit der ihn umgebenden Fläche bündig abschließt. Derartige Abdeckelemente sind nach längerer Gebrauchsdauer oftmals nur schwer herausnehmbar. Dies gilt sowohl für runde als auch für vieleckige Abdeckelemente.Covering elements of the aforementioned type, which may be both continuously formed and provided with passage openings, such as a grid, are usually inserted into a surface, such as a road surface or the bottom of a bath or a basement room, that the main body, which is usually plate-shaped is formed, is located in a recessed seat, wherein the body usually flush with the surrounding surface. Such cover elements are often difficult to remove after prolonged use. This applies to both round and polygonal cover elements.

Aus der EP 0 475 225 B1 ist ein Abdeckelement bekannt, das zum Erleichtern des Herausnehmens aus einem Sitz ein drehbares Hebeelement aufweist, das um eine vertikale Achse drehbar ist, wobei bei einer Verdrehung des Drehelementes eine Druckkraft auf eine Abdrückrampe ausgeübt wird, mittels derer das Abdeckelement anhebbar ist. Dieses Abdeckelement weist den Nachteil auf, dass die Betätigungskräfte während des Drehvorgangs relativ hoch sind, so dass zum Verdrehen des Hebeelements ein Werkzeug erforderlich ist. Zudem muss nach einem geringfügigen ersten Anheben durch Verdrehen des Hebeelements zum vollständigen Anheben des Abdeckelements ein weiteres Werkzeug an einer Randnase angesetzt werden. Ein weiterer Nachteil dieses Abdeckelements besteht darin, dass es in der Herstellung relativ kompliziert ist.From the EP 0 475 225 B1 For example, a cover member is known which, to facilitate removal from a seat, comprises a rotatable lifting member which is rotatable about a vertical axis, wherein upon rotation of the rotary member a compressive force is applied to an ejection ramp by means of which the cover member is raisable. This cover member has the disadvantage that the actuating forces during the turning operation are relatively high, so that a tool is required for rotating the lifting element. In addition, after a slight first lifting by rotating the lifting element for complete lifting of the cover a another tool can be attached to an edge nose. Another disadvantage of this cover element is that it is relatively complicated to manufacture.

Aus der DE 139 895 C ist ein Sinkkasten mit einer Schachtkammer und einem Rost bekannt, wobei der Rost über ein Hebelsystem anhebbar ist. Dieses Hebelsystem verbindet den Rost mit dem Boden der Schachtkammer. Wenn bei starkem Wasserzufluß der Druck auf den Boden der Schachtkammer einen bestimmten Wert übersteigt, klappt diese nach unten und hebt hierbei den Rost an, um den vollen Schactquerschnitt für den Wasserzufluß freizulegen.From the DE 139 895 C a sink box with a shaft chamber and a grate is known, wherein the grate is raised by a lever system. This lever system connects the grate to the bottom of the manhole chamber. If the pressure on the bottom of the manhole chamber exceeds a certain value in the case of a strong flow of water, it will fold down and lift the grate to expose the full Schakt cross-section for the flow of water.

Der Erfindung liegt das technische Problem zu Grunde, ein Abdeckelement der vorstehend erläuterten Art bereitzustellen, das von außen leicht anhebbar ist.The invention is based on the technical problem of providing a cover of the type described above, which is easily raised from the outside.

Hierzu schlägt die Erfindung ein Abdeckelement der eingangs beschriebenen Art vor, bei dem eine Hebelanordnung mit mindestens einem Hebel vorgesehen ist. Ein erstes Ende dieses mindestens einen Hebels ist so ausgeführt und positioniert, dass es von der Oberseite des Abdeckelements her manuell aus einer Ruhelage heraus betätigbar und so gegenüber dem Grundkörper verschwenkbar ist, dass ein zweites Ende des Hebels beim Verschwenken das Abdeckelement anhebt.For this purpose, the invention proposes a cover of the type described above, in which a lever arrangement is provided with at least one lever. A first end of this at least one lever is designed and positioned such that it can be actuated manually from a rest position from the top side of the cover element and pivoted relative to the base body such that a second end of the lever lifts the cover element during pivoting.

Erfindungsgemäß wird somit der Abdrückvorgang durch eine Hebelkonstruktion mittels eines Schwenkhebels verwirklicht. Dies erlaubt es, durch geeignete Hebelverhältnisse die Betätigungskräfte sehr gering zu halten. Zudem lässt sich eine derartige Hebelkonstruktion sehr kostengünstig produzieren.According to the invention thus the Abdrückvorgang is realized by a lever construction by means of a pivot lever. This makes it possible to keep the actuating forces very low by suitable leverage ratios. In addition, such a lever construction can be produced very inexpensively.

Der Hebel kann grundsätzlich an einer beliebigen Stelle angeordnet sein, wobei der oder die Hebel vorzugsweise im Bereich der den Rand des Abdeckelements umgebenden Fuge angeordnet sind. Es versteht sich für den Fachmann, dass die Anordnung des Hebels sowohl an dem Abdeckelement selbst als auch an einem das Abdeckelement umgebenden Bauteil, beispielsweise einem in den Boden eingelassenen Rahmen gelagert sein kann.The lever can in principle be arranged at any desired location, wherein the lever or levers are preferably arranged in the region of the joint surrounding the edge of the cover element. It is understood by those skilled in the art that the arrangement of the lever on both the cover itself and can also be mounted on a surrounding the cover member component, for example, a sunken into the ground frame.

Vorzugsweise ist der Hebel verschwenkbar an dem Grundkörper gelagert, wobei er in der Ruhelage bündig mit der Oberseite des Abdeckelements abschließt.Preferably, the lever is pivotally mounted on the base body, wherein it is flush in the rest position with the top of the cover.

Im Bereich des zweiten Endes des Hebels kann ein Verschlußelement angeordnet sein, das in der Ruhelage eine Verriegelung des Abdeckelements mit dem Sitz bewirkt. Der Hebel erfüllt somit gleichzeitig in der Ruhelage die Funktion des Verriegelns des Abdeckelements in dem das Abdeckelement aufnehmenden Sitz und die Funktion des Abdrückens von dem Sitz dann, wenn der Hebel aus seiner Ruhelage verschwenkt wird, wobei bei diesem Verschwenken gleichzeitig die Verriegelung aufgehoben wird.In the region of the second end of the lever, a closure element may be arranged, which causes a locking of the cover member with the seat in the rest position. Of the Lever thus fulfills the same function in the rest position, the function of locking the cover in the cover receiving the seat and the function of pushing off the seat when the lever is pivoted from its rest position, said at the same time the lock is released in this pivoting.

Es können zudem ein oder mehrere Rastelemente im Bereich des Hebels vorgesehen sein, die bewirken, dass der Hebel in seiner Ruhelage gehalten wird. Die Rastelemente werden hierbei so ausgewählt und bemessen, dass einerseits ein unbeabsichtigtes oder selbsttätiges Verschwenken des Hebels aus der Ruhelage vermieden wird und andererseits die Betätigungskräfte zum Verschwenken des Hebels nicht übermäßig erhöht sind.It can also be provided in the region of the lever one or more locking elements, which cause the lever is held in its rest position. The locking elements are in this case selected and dimensioned so that on the one hand unintentional or automatic pivoting of the lever is avoided from the rest position and on the other hand, the actuating forces for pivoting the lever are not excessively increased.

Insbesondere bei einer Ausführungsform, bei der der Hebel bündig mit der ihn umgebenden Oberfläche abschließt, ist vorzugsweise eine Ausnehmung in dem Grundkörper ausgebildet, die ein Ergreifen des Hebel erleichtert. Zudem kann an dem Hebel ein Griff vorgesehen sein, der das Anheben des Abdeckelements erleichtert. Wird der Hebel von der Oberseite des Abdeckelements aus nach oben verschwenkt, wird somit nicht nur ein Abdrücken des Abdeckelements von seinem Sitz bewirkt, sondern gleichzeitig ein Griff bereitgestellt, mit dem das Abdeckelement weiter angehoben werden kann.In particular, in an embodiment in which the lever is flush with the surface surrounding it, a recess is preferably formed in the base body, which facilitates gripping the lever. In addition, a handle may be provided on the lever, which facilitates the lifting of the cover. Thus, when the lever is pivoted upwardly from the top of the cover, not only is the cover displaced from its seat, but a handle is also provided to further raise the cover.

In einer bevorzugten Ausführungsform des erfindungsgemäßen Abdeckelements sind zwei Hebel vorgesehen. Die beiden ersten Enden der beiden Hebel sind mittels eines Verbindungselements miteinander verbunden, wobei dieses Verbindungselement einen Handgriff bildet. Vorzugsweise schließt der Handgriff in der Ruhelage bündig mit der Oberseite des Abdeckelements ab, wobei in der Oberseite des Grundkörpers eine Ausnehmung im Bereich des Handgriffes ausgebildet ist, die ein Ergreifen des Handgriffes durch eine Bedienperson erleichtert.In a preferred embodiment of the cover according to the invention two levers are provided. The two first ends of the two levers are connected to each other by means of a connecting element, wherein this connecting element forms a handle. Preferably, the handle in the rest position is flush with the top of the cover, wherein in the top of the body a recess in the region of the handle is formed, which facilitates gripping of the handle by an operator.

Im folgenden wird zunächst unter Bezug auf die Figuren 1 und 2 eine erste Ausführungsform eines erfindungsgemäßen Abdeckelements erläutert.The following is first with reference to the FIGS. 1 and 2 a first embodiment of a cover according to the invention explained.

Das Abdeckelement 1 weist einen plattenförmigen Grundkörper 10 auf, der in dem dargestellten Ausführungsbeispiel in einen Rahmen 50 eingesetzt ist. Der Rahmen 50 kann beispielsweise Bestandteil eines Abwasserschachtes sein, der in den Boden eines Kellers eingesetzt wird. Das Abdeckelement ist in diesem Fall ein Kellerablauf oder Gullydeckel mit mehreren Durchtrittsöffnungen 11. Es versteht sich, dass das Abdeckelement auch ohne Durchtrittsöffnungen und mit unterschiedlichsten Geometrien ausgeführt sein kann. Es versteht sich zudem, dass das Abdeckelement nicht zwangsläufig in einen Rahmen, sondern wahlweise auch in einen beliebig anders geformten Sitz eingesetzt werden kann.The cover element 1 has a plate-shaped base body 10, which is inserted into a frame 50 in the illustrated embodiment. The frame 50 may for example be part of a sewer manhole, which is inserted into the bottom of a cellar. The cover is in this case a basement drain or manhole cover with multiple openings 11. It is understood that the cover can be designed without openings and with different geometries. It is also understood that the cover is not inevitably in a frame, but optionally can be used in any differently shaped seat.

An dem Grundkörper 10 ist ein Bügel 23 verschwenkbar gelagert, der aus zwei Hebeln 20 und 21 sowie einem die Hebel 20 und 21 an ihren jeweiligen ersten Enden 20A, 21A miteinander verbindenden Verbindungselement 22 besteht, wobei das Verbindungselement 22 als Handgriff ausgebildet ist. Die Hebel 20, 21 sind verschwenkbar an dem Grundkörper 10 gelagert. Der Lagerpunkt beziehungsweise die Schwenkachse des Hebels 21 ist nicht mittig bezüglich der Länge des Hebels 21 angeordnet, sondern liegt näher an dem zweiten Ende 21B als an dem ersten Ende 21A. Entsprechendes gilt für den auf der gegenüber liegenden Seite angeordneten Hebel 20.On the main body 10, a bracket 23 is pivotally mounted, which consists of two levers 20 and 21 and a lever 20 and 21 at their respective first ends 20A, 21A interconnecting connecting element 22, wherein the connecting element 22 is formed as a handle. The levers 20, 21 are pivotally mounted on the base body 10. The pivot point of the lever 21 is not centered with respect to the length of the lever 21, but is closer to the second end 21B than to the first end 21A. The same applies to the arranged on the opposite side lever 20th

Der Bügel 23 und somit die Hebel 21 und 20 sind in den Figuren 1 und 2 in einer Betätigungsstellung gezeigt, in der sie mit einer Unterlage, auf der die Unterseite 13 des Grundkörpers 10 auf dem Sitz des Rahmens 50 aufliegt, in Berührung gelangen. Wird der Bügel 23 aus dieser Stellung weiter in Richtung des Pfeiles A verschwenkt, d. h. in Richtung der Senkrechten auf die Oberseite 12 des Grundkörpers 10, so drücken das zweite Ende 21B des Hebels 21 sowie das entsprechende zweite Ende des Hebels 20 auf diese Unterlage. Hierdurch wird der Grundkörper 10 von dem Sitz des Rahmens 50 abgehoben.The bracket 23 and thus the levers 21 and 20 are in the FIGS. 1 and 2 shown in an operating position in which they come with a pad on which the bottom 13 of the body 10 rests on the seat of the frame 50 in contact. If the bracket 23 is pivoted further from this position in the direction of the arrow A, ie in the direction of the vertical on the upper side 12 of the main body 10, the second end 21B of the lever 21 and the corresponding second end of the lever 20 press against this base. As a result, the main body 10 is lifted off the seat of the frame 50.

Auf Grund der zuvor erläuterten Hebelverhältnisse in Bezug auf die Lagerung der Hebel 20 und 21 ist der Hebelarm für die Betätigungskraft größer als der Hebelarm hinsichtlich der Druckkraft auf die Unterlage. Hierdurch kann mit einer relativ geringen Betätigungskraft eine große Haftkraft überwunden werden.Due to the above-described leverage with respect to the mounting of the levers 20 and 21, the lever arm for the operating force is greater than the lever arm with respect to the pressing force on the pad. As a result, a large adhesive force can be overcome with a relatively low actuating force.

In der Oberseite 12 des Grundkörpers 10 ist eine erste Ausnehmung 15 ausgebildet, in die der Bügel 23 mit dem Verbindungselement 22 und den Hebeln 20, 21 eingelegt werden kann. Diese Stellung ist als sogenannte Ruhestellung vorgesehen, in der der Bügel 23 bündig mit der Oberfläche 12 des Grundkörpers 10 abschließt. An der dem Grundkörper 10 zugewandten Seite des zweiten Endes 21B des Hebels 21 kann ein Rastvorsprung (nicht gezeigt) vorgesehen sein, der in der Ruhestellung mit einer entsprechenden Vertiefung in dem Grundkörper 10 in Eingriff gelangt. Hierdurch wird ein unbeabsichtigtes oder selbsttätiges Verschwenken des Hebels aus der Ruhelage verhindert.In the upper side 12 of the main body 10, a first recess 15 is formed, in which the bracket 23 with the connecting element 22 and the levers 20, 21 can be inserted. This position is called a rest position provided in which the bracket 23 is flush with the surface 12 of the base body 10. On the side facing the base body 10 of the second end 21B of the lever 21, a latching projection (not shown) may be provided which engages in the rest position with a corresponding recess in the base body 10 in engagement. As a result, an unintentional or automatic pivoting of the lever is prevented from the rest position.

Eine zweite Ausnehmung 16 in der Oberseite 12 des Grundkörpers 10 dient dazu, ein Ergreifen des Handgriffs 22 zu ermöglichen, wenn sich dieser in der Ruhelage befindet. Eine weitere Ausnehmung 17 in einem seitlichen Bereich des Grundkörpers 10 dient dazu, ein Ergreifen des Bügels 23 von der Seite her zu erleichtern. Es versteht sich, dass die Vertiefung 16 dem Ergreifen des Bügels von der Oberseite 12 des Grundkörpers 10 dient und dass die Vertiefung 17 einem Ergreifen des Bügels 23 von der Seite her dient, insbesondere dann, wenn das Abdeckelement 1 nicht in eine Vertiefung eingelegt ist.A second recess 16 in the top 12 of the body 10 serves to allow gripping the handle 22 when it is in the rest position. A further recess 17 in a lateral region of the base body 10 serves to facilitate gripping of the bracket 23 from the side. It is understood that the recess 16 is used to grasp the bracket from the top 12 of the base 10 and that the recess 17 serves to grasp the bracket 23 from the side, in particular when the cover 1 is not inserted into a recess.

Die Figuren 3 bis 5 zeigen eine zweite Ausführungsform der Erfindung, die im wesentlichen der ersten Ausführungsform gemäß den Figuren 1 und 2 entspricht und bei der gleiche beziehungsweise entsprechende Elemente mit dem gleichen Bezugszeichen versehen sind.The FIGS. 3 to 5 show a second embodiment of the invention, which is substantially the first embodiment according to the FIGS. 1 and 2 corresponds and at the same or corresponding elements are provided with the same reference numerals.

Fig. 3 zeigt ein Abdeckelement 1 mit einem plattenförmigen Grundkörper 10, in den ein Bügel 23 mit zwei Hebeln 20, 21 und einem Handgriff 22, die materialeinheitlich ausgebildet sind, bündig mit der Oberfläche 12 des Grundkörpers 10 in einer entsprechenden Ausnehmung in einer Ruhestellung liegt. Der Handgriff 22 verbindet die ersten Enden 20A und 21A der Hebel 20 und 21 miteinander. Die zweiten Enden 20B, 21B der Hebel 20, 21 sind so ausgeführt, dass sie den Grundkörper 10 durch entsprechenden Druck auf eine Unterlage von der Unterlage abheben, wenn der Bügel 23 in eine Betätigungsstellung verschwenkt wird, wie sie in Fig. 4 dargestellt ist. Fig. 3 shows a cover 1 with a plate-shaped base body 10, in which a bracket 23 with two levers 20, 21 and a handle 22, which are formed of the same material, is flush with the surface 12 of the body 10 in a corresponding recess in a rest position. The handle 22 connects the first ends 20A and 21A of the levers 20 and 21 with each other. The second ends 20B, 21B of the levers 20, 21 are designed so that they lift the main body 10 by appropriate pressure on a pad from the pad when the bracket 23 in a Actuating position is pivoted, as in Fig. 4 is shown.

An den Hebeln 20, 21 sind Verschlusselemente in Form von Haken 20C, 21C so angeordnet, dass sie in entsprechende Verriegelungselemente (nicht dargestellt), welche am Sitz des Abdeckelements 1 vorgesehen sind, eingreifen, wenn sich der Bügel 23 in der Ruhestellung befindet, wie in den Figuren 3 und 5 gezeigt. Es versteht sich, dass die Haken 20C, 21C beim Verschwenken des Bügels 23 aus der in den Figuren 3 und 5 gezeigten Ruhestellung in die in Fig. 4 gezeigte Stellung außer Eingriff mit den nicht dargestellten Verriegelungselementen gelangen, bevor die zweiten Enden 20B, 21B der Hebel 20, 21 den Grundkörper 10 von dem Sitz (in den Figuren 3 bis 5 nicht dargestellt) abdrücken.On the levers 20, 21 closure elements in the form of hooks 20C, 21C are arranged so that they engage in corresponding locking elements (not shown), which are provided on the seat of the cover 1, when the bracket 23 is in the rest position, such as in the Figures 3 and 5 shown. It is understood that the hooks 20 C, 21 C when pivoting the bracket 23 from the in the Figures 3 and 5 shown rest position in the in Fig. 4 shown position out of engagement with the locking elements, not shown, before the second ends 20 B, 21 B of the lever 20, 21, the base body 10 from the seat (in the FIGS. 3 to 5 not shown).
