Definitions
- the invention relates to a cover for a floor opening according to the preamble of claims 1 and 8.
- Covers with which a bottom opening, for example a shaft opening or an opening in a ceiling, can be closed but, if necessary, opened without problems, are known in many designs.
- the lid can have a rectangular, elliptical or circular shape, while in most cases the frame is designed with a quadrangular outer contour, regardless of the shape of the lid. In certain applications it is required that the lid forms a tight seal for the bottom opening.
- Known solutions use relatively soft seals made of rubber or a rubber-elastic plastic to achieve this requirement. Although a good seal can be achieved in this way, problems arise if the seal is damaged or moved during opening, so that the seal is no longer guaranteed when the bottom opening is subsequently closed.
- a sealing device for sealing a cover on the bearing surface of the associated frame is known, in which the deficiencies described do not occur.
- the cover can have support surfaces inclined to the cover plane, which cooperate with corresponding bearing surfaces of the frame.
- An annular recess, which is filled with a sealing compound, is recessed in the support surface or in the support surface. If the lid is carefully opened and replaced again, the sealing effect remains intact. However, if the cover has not been removed carefully, the complete seal is also achieved. If necessary, some sealing compound must be pressed into the recess, for which purpose corresponding openings are provided in the lid or in the frame.
- the use of the known sealing device is particularly suitable for lids and frames, the support surfaces and bearing surfaces of which are inclined to the lid plane. If the lid has a square shape, a perfect fit of the lid in the frame is guaranteed. However, if the lid has a circular shape, it is necessary to use soft seals and to screw the lid onto the frame while compressing the seal. However, this can cause the problems mentioned when opening such a lid.
- the invention is based on the consideration that a good seal can be achieved with a cover with a circular or elliptical cover if the cover or its support surface is designed such that the latter only fits into the bearing surface of the frame in a single position . It is obviously not sufficient for this that the cover has the shape of a cylindrical piece or a truncated cone. Because such a lid can be used in any way in the frame. But even if the circular shape of the lid is replaced by an elliptical shape, the lid can still be inserted into the frame in two different positions. However, the situation is different if the cover is designed as part of an oblique circular cone or an oblique cylinder, since then no point of the support surface is repeated on the circumference. However, this is the condition for the cover to have a support surface which can only be fitted into the support surface of the frame in a single position.
- Fig. 1 is shown schematically the shape of a lid, the support surface of which forms part of the lateral surface of an oblique cone.
- the lid then represents a section of this inclined cone, which is limited by appropriate cuts.
- the oblique circular cone is denoted by 1 and its axis by 2.
- the upper and lower cuts 3, 4 are circular, this means that the diameters 5, 6 of these cuts are perpendicular to axes 7, 8.
- the cuts 3, 4 are, however, elliptical surfaces if the axes of these cuts are perpendicular to the axis 2 of the oblique circular cone.
- the starting figure for forming the cover is an oblique circular cylinder 9, see FIG. 2 and if the upper section 3 and the lower section 4 are circular surfaces, these sections are perpendicular to axes 7, 8.
- the cuts 3, 4 are elliptical surfaces.
- lids are also possible in which the top side is circular and the bottom side is elliptical, see FIG. 7.
- the surface can also be elliptical and the bottom side circular, see FIG. 8.
- FIG. 9 Another variant is shown in FIG. 9.
- the elliptical side is rotated by 90 ° with respect to the elliptical sides of FIGS. 7 and 8.
- FIGS. 10 and 11 Further embodiments are shown in FIGS. 10 and 11. This is based on the consideration that the circular or elliptical top and bottom sides can be approximated by polygons. In this case too, lids are obtained which have the same properties as the lids with circular or elliptical top and bottom sides.
- Fig. 10 shows a lid in the form of an oblique truncated pyramid with a polygonal top and bottom, the polygon being a regular octagon.
- FIG. 11 shows a cover in the form of an oblique prism with a polygonal top and bottom, the polygon being a regular octagon.
- FIG. 10 corresponds approximately to FIG. 3 and FIG. 11 approximately corresponds to FIG. 5.
- an n-corner with any number of corners can be used instead of the octagon.
- FIG. 13-16 shows the shape of the frame resulting from the design of the cover as an oblique cone or cylinder.
- a cover according to FIG. 12 is assumed, which can correspond to one of the embodiments according to FIGS. 3-6.
- FIG. 13 and 14 show the section of the cover 10 and the frame 11 along the line Xlll-Xlll in Fig. 12. From this section it can be seen that the inclination of the support surface of the cover 10 and the bearing surface of the frame 11 on the opposite sides is different.
- the covers described have significant advantages. Thanks to the special shape of the cover, the lid can be easily inserted into the frame and aligns itself. It is also advantageous that the cover cannot be rotated in the frame, so that the same point on the support surface of the
- Cover lies on the corresponding point of the bearing surface of the frame. In view of the small play that can be maintained between the cover and the frame and the parts that are covered with grease, a reliable sealing of the cover is guaranteed.
- the sealing device according to EP-A-0 142 160 can also be used for these embodiments.
- the covers described with a lock e.g. according to CH Patent No. 677 379 can be used. This can expediently be provided in the area 12 of the cover 10.
- the described lids can be made from different materials, for example from cast iron with lamellar or spherical graphite or from plastic. Machining of the support surface of the cover and the support surface of the frame is required, for which purpose special machines are expediently used.

Abstract
Description
Die Erfindung betrifft eine Abdeckung für eine Bodenöffnung gemäss dem Oberbegriff der Ansprüche 1 und 8.The invention relates to a cover for a floor opening according to the preamble of claims 1 and 8.
Abdeckungen, mit denen eine Bodenöffnung, beispielsweise eine Schachtöffnung oder eine Oeffnung in einer Decke, verschlossen, jedoch bei Bedarf problemlos geöffnet werden kann, sind in vielen Ausführungen bekannt. Der Deckel kann hierbei Rechteckform, elliptische Form oder Kreisform aufweisen, während der Rahmen unabhängig von der Form des Deckels in den meisten Fällen mit viereckförmiger Aussenkontur ausgebildet ist. In bestimmten Anwendungsfällen wird verlangt, dass der Deckel einen dichten Abschluss der Bodenöffnung bildet. Bekannte Lösungen verwenden zur Erreichung dieser Forderung verhältnismässig weiche Dichtungen aus Gummi oder einem gummielastischen Kunststoff. Damit kann zwar eine gute Abdichtung erreicht werden, jedoch ergeben sich Probleme, wenn beim Oeffnen die Dichtung beschädigt oder verschoben wird, so dass beim nachfolgenden Verschliessen der Bodenöffnung die Dichtheit nicht mehr gewährleistet ist.Covers with which a bottom opening, for example a shaft opening or an opening in a ceiling, can be closed but, if necessary, opened without problems, are known in many designs. The lid can have a rectangular, elliptical or circular shape, while in most cases the frame is designed with a quadrangular outer contour, regardless of the shape of the lid. In certain applications it is required that the lid forms a tight seal for the bottom opening. Known solutions use relatively soft seals made of rubber or a rubber-elastic plastic to achieve this requirement. Although a good seal can be achieved in this way, problems arise if the seal is damaged or moved during opening, so that the seal is no longer guaranteed when the bottom opening is subsequently closed.
Es ist aus EP-A-0 142 160 eine Abdichtungsvorrichtung zum Abdichten eines Deckels an der Auflagefläche des zugehörigen Rahmens bekannt, bei welcher die geschilderten Mängel nicht auftreten. Der Deckel kann hierbei zur Deckelebene geneigte Abstützflächen aufweisen, welche mit entsprechenden Auflageflächen des Rahmens zusammenwirken. In der Abstützfläche oder in der Auflagefläche ist eine ringförmige Ausnehmung ausgespart, die mit einer Dichtungsmasse gefüllt ist. Wird der Deckel sorgfältig geöffnet und wieder engesetzt, bleibt die Dichtwirkung vollständig erhalten. Sollte jedoch die Entfernung des Deckels nicht sorgfältig vorgenommen worden sein, wird die vollständige Abdichtung ebenfalls erreicht. Gegebenenfalls muss etwas Dichtungsmasse in die Ausnehmung eingepresst werden, wozu entsprechende Oeffnungen im Deckel oder im Rahmen vorgesehen sind.From EP-A-0 142 160 a sealing device for sealing a cover on the bearing surface of the associated frame is known, in which the deficiencies described do not occur. The cover can have support surfaces inclined to the cover plane, which cooperate with corresponding bearing surfaces of the frame. An annular recess, which is filled with a sealing compound, is recessed in the support surface or in the support surface. If the lid is carefully opened and replaced again, the sealing effect remains intact. However, if the cover has not been removed carefully, the complete seal is also achieved. If necessary, some sealing compound must be pressed into the recess, for which purpose corresponding openings are provided in the lid or in the frame.
Die Anwendung der bekannten Abdichtungsvorrichtung eignet sich besonders bei Deckeln und Rahmen, deren Abstützflächen und Auflageflächen zur Deckelebene geneigt sind. Weist der Deckel Viereckform auf, wird ein einwandfreier Sitz des Deckels im Rahmen gewährleistet. Weist jedoch der Deckel Kreisform auf, ist es erforderlich, Weichdichtungen zu verwenden und den Deckel unter Zusammenpressung der Dichtung auf den Rahmen zu schrauben. Damit können jedoch beim Oeffnen eines solchen Deckels die erwähnten Probleme auftreten.The use of the known sealing device is particularly suitable for lids and frames, the support surfaces and bearing surfaces of which are inclined to the lid plane. If the lid has a square shape, a perfect fit of the lid in the frame is guaranteed. However, if the lid has a circular shape, it is necessary to use soft seals and to screw the lid onto the frame while compressing the seal. However, this can cause the problems mentioned when opening such a lid.
Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, eine Abdeckung der eingangs beschriebenen Art so weiter auszugestalten, dass auch runde und ovale Deckel problemlos und ohne die erwähnten Nachteile zuverlässig dicht abgeschlossen werden können.This is where the invention comes in, which is based on the object of further developing a cover of the type described at the outset in such a way that even round and oval lids can be reliably sealed without any problems and without the disadvantages mentioned.
Diese Aufgabe wird gemäss der Erfindung durch die kennzeichnenden Merkmale des Anspruchs 1 oder 8 gelöst.This object is achieved according to the invention by the characterizing features of claim 1 or 8.

Die Erfindung geht von der Ueberlegung aus, dass bei einer Abdekkung mit einem kreisförmigen oder elliptischen Deckel dann eine gute Abdichtung erreicht werden kann, wenn der Deckel bzw. seine Abstützfläche so ausgebildet ist, dass letztere nur in einer einzigen Stellung in die Auflagefläche des Rahmens passt. Hierzu genügt es offensichtlich nicht, dass der Deckel die Form eines Zylinderstückes oder eines Kegelstumpfes aufweist. Denn ein solcher Deckel kann in beliebiger Weise in den Rahmen eingesetzt werden. Aber auch dann, wenn die Kreisform des Deckels durch eine elliptische Form ersetzt wird, kann der Deckel immer noch in zwei verschiedenen Stellungen in den Rahmen eingesetzt werden. Anders sieht es jedoch aus, wenn der Deckel als Teil eines schiefen Kreiskegels oder eines schiefen Zylinders ausgebildet ist, da dann keine Stelle der Abstützfläche sich am Umfang wiederholt. Dies ist jedoch die Bedingung dafür, dass der Deckel eine Abstützfläche aufweist, die nur in einer einzigen Stellung passend in die Auflagefläche des Rahmens eingesetzt werden kann.The invention is based on the consideration that a good seal can be achieved with a cover with a circular or elliptical cover if the cover or its support surface is designed such that the latter only fits into the bearing surface of the frame in a single position . It is obviously not sufficient for this that the cover has the shape of a cylindrical piece or a truncated cone. Because such a lid can be used in any way in the frame. But even if the circular shape of the lid is replaced by an elliptical shape, the lid can still be inserted into the frame in two different positions. However, the situation is different if the cover is designed as part of an oblique circular cone or an oblique cylinder, since then no point of the support surface is repeated on the circumference. However, this is the condition for the cover to have a support surface which can only be fitted into the support surface of the frame in a single position.
In Fig. 1 ist schematisch dargestellt, welche Form ein Deckel aufweist, dessen Abstützfläche einen Teil der Mantelfläche eines schiefen Kegels darstellt. Der Deckel stellt dann einen Abschnitt dieses schiefen Kegels dar, der durch entsprechende Schnitte begrenzt ist.In Fig. 1 is shown schematically the shape of a lid, the support surface of which forms part of the lateral surface of an oblique cone. The lid then represents a section of this inclined cone, which is limited by appropriate cuts.
In Fig. 1 ist der schiefe Kreiskegel mit 1 und seine Achse mit 2 bezeichnet. Wenn der obere und der untere Schnitt 3, 4 kreisförmig ist, bedeutet dies, dass die Durchmesser 5, 6 dieser Schnitte senkrecht zu Achsen 7, 8 liegen. Die Schnitte 3, 4 sind jedoch elliptische Flächen, wenn die Achsen dieser Schnitte senkrecht zur Achse 2 des schiefen Kreiskegels liegen. Ist jedoch die Ausgangsfigur zur Ausbildung des Deckels ein schiefer Kreiszylinder 9, siehe Fig. 2 und sind hierbei der obere Schnitt 3 und der untere Schnitt 4 Kreisflächen, liegen diese Schnitte senkrecht zu Achsen 7, 8.In Fig. 1, the oblique circular cone is denoted by 1 and its axis by 2. If the upper and
Liegen diese Schnitte senkrecht zur Achse 2 des schiefen Zylinders 9, so sind die Schnitte 3, 4 elliptische Flächen.If these cuts are perpendicular to the
Auf diese Weise werden aus dem schiefen Kreiskegel 1 und dem schiefen Kreiszylinder 9 vier Ausschnitte ausgeschnitten, die als Deckel verwendet werden können. Es sind dies ein kreisförmiger, schiefer Kegelstumpf nach Fig. 3, ein elliptischer, schiefer Kegelstumpf nach Fig. 4, ein schiefes, kreisförmiges Zylinderstück nach Fig. 5 und ein schiefes, elliptisches Zylinderstück nach Fig. 6.In this way, four cutouts are cut out of the oblique circular cone 1 and the oblique circular cylinder 9, which can be used as a lid. These are a circular, oblique truncated cone according to FIG. 3, an elliptical, oblique truncated cone according to FIG. 4, an oblique, circular cylinder piece according to FIG. 5 and an oblique, elliptical cylinder piece according to FIG. 6.
Es sind jedoch auch Deckel möglich, bei denen die Oberseite kreisförmig und die Unterseite elliptisch ist, siehe Fig. 7. Es kann aber auch die Oberfläche elliptisch und die Unterseite kreisförmig sein, siehe Fig. 8.However, lids are also possible in which the top side is circular and the bottom side is elliptical, see FIG. 7. However, the surface can also be elliptical and the bottom side circular, see FIG. 8.
Eine weitere Variante ist in Fig. 9 dargestellt. Bei dieser ist die elliptische Seite gegenüber den elliptischen Seiten von Fig. 7 und 8 um 90° gedreht.Another variant is shown in FIG. 9. In this case, the elliptical side is rotated by 90 ° with respect to the elliptical sides of FIGS. 7 and 8.
Weitere Ausführungsformen sind in den Figuren 10 und 11 dargestellt. Hierbei geht man von der Ueberlegung aus, dass man die kreisförmigen oder elliptischen Ober- und Unterseiten durch Polygone annähern kann. Auch in diesem Fall erhält man Deckel, welche dieselben Eigenschaften aufweisen wie die Deckel mit kreisrunden oder elliptischen Ober- und Unterseiten aufweisen.Further embodiments are shown in FIGS. 10 and 11. This is based on the consideration that the circular or elliptical top and bottom sides can be approximated by polygons. In this case too, lids are obtained which have the same properties as the lids with circular or elliptical top and bottom sides.
Fig. 10 zeigt einen Deckel in Form eines schiefen Pyramidenstumpfes mit polygonförmiger Ober- und Unterseite, wobei das Polygon ein regelmässiges Achteck ist.Fig. 10 shows a lid in the form of an oblique truncated pyramid with a polygonal top and bottom, the polygon being a regular octagon.
Fig. 11 zeigt einen Deckel in Form eines schiefen Prismas mit polygonförmiger Ober- und Unterseite, wobei das Polygon ein regelmässiges Achteck ist. Fig. 10 entspricht etwa Fig. 3 und Fig. 11 etwa Fig. 5. Es kann jedoch anstelle des Achteckes ein n-Eck mit beliebiger Zahl der Ecken verwendet werden.Fig. 11 shows a cover in the form of an oblique prism with a polygonal top and bottom, the polygon being a regular octagon. FIG. 10 corresponds approximately to FIG. 3 and FIG. 11 approximately corresponds to FIG. 5. However, an n-corner with any number of corners can be used instead of the octagon.
In Fig. 13 - 16 ist die sich aus der Ausführung des Deckels als schiefer Kegel oder Zylinder ergebende Form des Rahmens dargestellt. Hierbei wird von einem Deckel gemäss Fig. 12 ausgegangen, welcher einer der Ausführungsformen nach Fig. 3 - 6 entsprechen kann.13-16 shows the shape of the frame resulting from the design of the cover as an oblique cone or cylinder. Here, a cover according to FIG. 12 is assumed, which can correspond to one of the embodiments according to FIGS. 3-6.
Fig. 13 und 14 zeigen den Schnitt des Deckels 10 und des Rahmens 11 längs der Linie Xlll - Xlll in Fig. 12. Aus diesem Schnitt ist erkennbar, dass die Neigung der Abstützfläche des Deckels 10 und der Auflagefläche des Rahmens 11 an den gegenüberliegenden Seiten unterschiedlich ist.13 and 14 show the section of the
Fig. 15 und 16 zeigen einen Schnitt des Deckels 10 und des Rahmens 11 längs der Linie XV - XV. In diesem Schnitt weisen die Abstützfläche des Deckels 10 und die Auflagefläche des Rahmens 11 an den gegenüberliegenden Seiten dieselbe Neigung auf. Trotzdem ist es nicht möglich, den Deckel 10 in anderer Weise in den Rahmen 11 einzufügen als in der in Fig. 13 dargestellten Lage.15 and 16 show a section of the
Die beschriebenen Abdeckungen weisen wesentliche Vorteile auf. Dank der besonderen Form der Abdeckung kann der Deckel leicht in den Rahmen eingesetzt werden und richtet sich selbst aus. Vorteilhaft ist weiter, dass der Deckel im Rahmen nicht gedreht werden kann, so dass immer dieselbe Stelle der Abstützfläche desThe covers described have significant advantages. Thanks to the special shape of the cover, the lid can be easily inserted into the frame and aligns itself. It is also advantageous that the cover cannot be rotated in the frame, so that the same point on the support surface of the
Deckels auf der entsprechenden Stelle der Auflagefläche des Rahmens liegt. Im Hinblick auf das dadurch einhaltbare geringe Spiel zwischen dem Deckel und dem Rahmen und den Teilen, die mit Fett belegt werden, ist eine zuverlässige Abdichtung der Abdeckung gewährleistet. Es kann für diese Ausführungsformen aber auch die Abdichtungsvorrichtung gemäss EP-A-0 142 160 verwendet werden. Weiter sei noch erwähnt, dass selbstverständlich auch die beschriebenen Abdeckungen mit einer Verriegelung, z.B. nach CH-Patent Nr. 677 379, verwendet werden können. Diese kann zweckmässig im Bereich 12 des Deckels 10 vorgesehen werden.Cover lies on the corresponding point of the bearing surface of the frame. In view of the small play that can be maintained between the cover and the frame and the parts that are covered with grease, a reliable sealing of the cover is guaranteed. However, the sealing device according to EP-A-0 142 160 can also be used for these embodiments. It should also be mentioned that, of course, the covers described with a lock, e.g. according to CH Patent No. 677 379 can be used. This can expediently be provided in the
Die beschriebenen Deckel können aus verschiedenen Materialien hergestellt sein, beispielsweise aus Gusseisen mit lamellarem oder kugelförmigem Graphit oder aus Kunststoff. Hierbei ist eine Bearbeitung der Abstützfläche des Deckels und der Auflagefläche des Rahmens erforderlich, wozu zweckmässig Spezialmaschinen eingesetzt werden.The described lids can be made from different materials, for example from cast iron with lamellar or spherical graphite or from plastic. Machining of the support surface of the cover and the support surface of the frame is required, for which purpose special machines are expediently used.
Für die zeichnerischen Darstellungen der verschiedenen Ausführungsformen wurden schematische Darstellungen gewählt, da dadurch die prinzipielle Form der Abstützflächen des Deckels und der Auflageflächen des Rahmens besser erkennbar sind. Selbstverständlich können beispielsweise auf der Unterseite des Deckels Rippen angebracht sein. Die Oberseite kann eine Ausnehmung enthalten, welche mit Bitumen oder Beton gefüllt werden kann. Auch kann der Rahmen zusätzliche Rippen und Stege aufweisen; auch kann er doppelwandig ausgeführt sein. Die Ausbildung der Abstützfläche des Deckels und der Auflagefläche des Rahmens ergeben sich aus der gewählten Form.For the graphic representations of the various embodiments, schematic representations were chosen, since this makes the basic shape of the support surfaces of the cover and the bearing surfaces of the frame easier to see. Of course, ribs can be attached to the underside of the cover, for example. The top can contain a recess which can be filled with bitumen or concrete. The frame can also have additional ribs and webs; it can also be double-walled. The design of the support surface of the lid and the support surface of the frame result from the shape chosen.
