Abstract

Mounted in the cover (2) is a locking device (10) which is composed of a closing member (11) with arms (12) and a mounting bar (14) with a mounting and actuating device (15). The mounting bar (14) and the mounting and actuating device (15) lie in a bore (5) and a widened bore part (6), a shoulder (7) being formed on which a bearing face (17) of the mounting and actuating device (15) is supported. The ends of the arms (12) project into a guide link (20) which is integrally formed in the inner flange (3) of the frame (1). The guide link (20) has a sloping flank (21) which increasingly elastically deforms the arms (12) in a bending fashion. In the closed position, the arms snap into a catch recess (22) at the end of the sloping flank (21). This results in interlocking with pretension. <IMAGE>

Description

Die Erfindung betrifft eine Verriegelungsvorrichtung, welche einen Deckel oder Rost in einem Rahmen formschlüssig zu haltern bestimmt ist.The invention relates to a locking device which is intended to hold a lid or grate in a frame in a form-fitting manner.

Es ist bekannt, Schächte und andere Bodenöffnungen mit einer Abdeckung zu versehen, die im wesentlichen aus einem Deckel oder Rost besteht, der in einem Rahmen gelagert ist. Unter dem Begriff "Rahmen" werden nicht nur rahmenartige Abstützungen für den Deckel oder den Rost, sondern alle Ausführungen von Rändern verstanden, die der Lagerung des Deckels oder des Rostes dienen. Bei den bekannten Ausführungsformen werden ein oder mehr Deckel oder Roste in einen Rahmen eingelegt, wobei im allgemeinen keine Vorrichtung zum Festhalten des Deckels im Rahmen vorgesehen wird. Da bisher die Deckel und Roste verhältnismässig schwer ausgebildet wurden, besteht keine besondere Notwendigkeit zum Festhalten derselben im Rahmen.It is known to provide manholes and other floor openings with a cover which essentially consists of a cover or grate which is mounted in a frame. The term "frame" is not only understood to mean frame-like supports for the cover or the grate, but also all designs of edges which serve to support the cover or the grate. In the known embodiments, one or more lids or grids are placed in a frame, generally no device for holding the lid in the frame is provided. Since the lids and grids have been made relatively heavy, there is no particular need to hold them in the frame.

Um Kosten- und Materialeinsparungen zu erreichen, wurden die Deckel und Roste konstruktiv verbessert und/oder aus einem höher belastbaren Material, z. B. aus duktilem Gusseisen anstelle von gewöhnlichem Gusseisen, hergestellt, was zu einer leichteren Bauweise führte. Da solche Deckel oder Roste eine höhere Elastizität aufweisen, tritt die Notwendigkeit auf, Halterungen vorzusehen, mit denen die Deckel oder die Roste im Rahmen festgehalten werden.In order to achieve cost and material savings, the lids and gratings have been improved in design and / or made of a more resilient material, e.g. B. made of ductile cast iron instead of ordinary cast iron, which led to a lighter design. Because such lids or grids have greater elasticity have the need to provide brackets with which the lid or the grids are held in the frame.

Bei einer älteren Ausführungsform einer Halterung der Anmelderin wird eine im Deckel oder im Rost einsetzbare Verriegelungsvorrichtung verwendet, von welcher Teile mit Partien des Rahmens zusammenwirken, derart, dass mit diesen Teilen und Partien ein Formschluss oder ein Reibschluss, gegebenenfalls verbunden mit einer Blockierungsmöglichkeit, gebildet wird, wodurch eine zuverlässige Halterung des Deckels oder des Rostes, allerdings teilweise mit Spiel, entsteht. Diese ältere Verriegelungsvorrichtung kann jedoch den Deckel oder den Rost nicht mit einer Vorspannkraft im Rahmen festhalten.In an older embodiment of a holder by the applicant, a locking device which can be used in the lid or in the grate is used, parts of which interact with parts of the frame in such a way that a positive or frictional connection, possibly connected with a blocking possibility, is formed with these parts and parts , which creates a reliable mounting of the lid or the grate, albeit with some play. However, this older locking device cannot hold the lid or the grate in the frame with a pretensioning force.

Hier setzt die Erfindung ein, der die Aufgabe zugrundeliegt, eine Verriegelungsvorrichtung der eingangs beschriebenen Art so weiter auszubilden, dass der Deckel oder der Rost mit einer Vorspannkraft im Rahmen gehalten ist.This is where the invention comes in, which is based on the object of further developing a locking device of the type described at the outset in such a way that the cover or the grate is held in the frame with a pretensioning force.

Diese Aufgabe wird gemäss der Erfindung durch eine Verriegelungsvorrichtung mit einem Schliessglied gelöst, welches mit mindestens zwei miteinander verbundenen Armen versehen ist, an deren Verbindungsstelle ein von den Armen abragender Lagerungsstab mit einer Lagerungs- und Betätigungsvorrichtung angeordnet und fest mit den Armen verbunden ist. Dadurch wird erreicht, dass die Arme zum Vorspannen des Deckels im Rahmen verwendbar sind.This object is achieved according to the invention by a locking device with a locking member which is provided with at least two interconnected arms, at the connection point of which a support rod projecting from the arms is arranged with a storage and actuating device and is firmly connected to the arms. This ensures that the arms can be used to pretension the cover in the frame.

Die Erfindung umfasst deshalb auch einen Deckel oder Rost und einen Rahmen, deren Aufgabe es ist, das Vorspannen der erfindungsgemässen Verriegelungsvorrichtung zu ermöglichen.The invention therefore also includes a cover or grate and a frame, the task of which is to enable the locking device according to the invention to be pretensioned.

Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass das Schliessglied der Verriegelungsvorrichtung mit dem Lagerungsstab in einer Bohrung des Deckels oder des Rostes drehbar gelagert und mit den Enden seiner Arme unter gleichzeitiger elastischer Verformung derselben und unter Bildung eines Formschlusses an einer Führungskulisse im Deckel oder im Rost und/oder im Rahmen gehalten ist.This object is achieved according to the invention in that the closing member of the locking device with the storage rod in a bore of the lid or the grate is rotatably supported and is held with the ends of its arms with simultaneous elastic deformation of the same and with the formation of a form fit on a guide link in the lid or in the grate and / or in the frame.

Die Erfindung geht von der Ueberlegung aus, dass die Verriegelungsvorrichtung derart ausgebildet sein soll, dass an ihr eine elastische Verformung und damit eine Vorspannkraft erzeugt werden kann, so dass der zu halternde Teil nicht nur formschlüssig in seiner Lagerung gehalten, sondern auch mit einer Vorspannkraft auf seine Lagerung gepresst werden kann. In Fig. 1 ist eine erste Ausführungsform einer Verriegelungsvorrichtung dargestellt. Ueber einer Oeffnung (nicht dargestellt) ist ein Rahmen 1 als Abschluss der Oeffnung angeordnet, in welchen ein Deckel 2 eingesetzt ist. Der Deckel 2 ist auf einem Innenflansch 3 des Rahmen 2 abgestützt. Der Rahmen 1 und der Deckel 2 fluchten auf der Oberseite 4, welche auch gewöhnlich das Niveau eines Bodens (nicht dargestellt) bildet, in welchem der Rahmen 1 mit dem Deckel 2 eingebaut ist.The invention is based on the consideration that the locking device should be designed in such a way that an elastic deformation and thus a pretensioning force can be generated on it, so that the part to be held is not only held positively in its storage but also with a pretensioning force its storage can be pressed. 1 shows a first embodiment of a locking device. A frame 1, in which a cover 2 is inserted, is arranged as an end of the opening above an opening (not shown). The cover 2 is supported on an inner flange 3 of the frame 2. The frame 1 and the cover 2 are aligned on the upper side 4, which also usually forms the level of a floor (not shown) in which the frame 1 with the cover 2 is installed.

Im Zentrum des Deckels 2, der eine beliebige Form, z.B. Kreisform, Polygonform, Rechteckform oder Ovalform aufweisen kann, ist eine Bohrung 5 angeordnet, die auf der Oberseite des Deckels in eine erweiterte Bohrungspartie 6 übergeht, wobei zwischen der Bohrung 5 und der erweiterten Bohrungspartie 6 eine kreisringförmige Schulter 7 gebildet wird.In the center of the cover 2, which has any shape, e.g. Can have a circular shape, polygonal shape, rectangular shape or oval shape, a bore 5 is arranged which merges into an enlarged bore section 6 on the top of the cover, an annular shoulder 7 being formed between the bore 5 and the enlarged bore section 6.

Zum Festhalten des Deckels 2 im Rahmen 1 dient eine Verriegelungsvorrichtung 10. Die Verriegelungsvorrichtung 10 weist ein Schliessglied 11 auf, das sich aus zwei Armen 12 zusammensetzt. Es können auch mehr als zwei Arme 12, z.B. drei oder vier, verwendet werden, welche mit dem einen Ende an einer Verbindungsstelle 13 zusammenstossen und fest miteinander verbunden sind. An der Verbindungsstelle 13 ist ein Lagerungsstab 14 mit den Armen 12 fest verbunden, der im wesentlichen senkrecht zu den Armen 12 verläuft. Am freien Ende des Lagerungsstabes 14 ist eine Lagerungs- und Betätigungsvorrichtung 15 angeordnet, welcher als Kopf 16 ausgebildet ist. Der Kopf 16 weist beispielsweise eine Sechskantform auf, auf welche ein Sechskant-Schlüssel aufgesetzt werden kann, mit welchem die Verriegelungsvorrichtung 10 gedreht werden kann. Der Kopf 16 ist auf seiner Unterseite als Lagerfläche 17 ausgebildet, die sich auf der Schulter 7 zwischen der Bohrung 5 und der erweiterten Bohrungspartie 6 befindet.A locking device 10 is used to hold the cover 2 in the frame 1. The locking device 10 has a closing member 11, which is composed of two arms 12. It is also possible to use more than two arms 12, for example three or four, which collide with one end at a connection point 13 and firmly with one another are connected. At the connection point 13, a support rod 14 is firmly connected to the arms 12, which runs essentially perpendicular to the arms 12. At the free end of the storage rod 14, a storage and actuation device 15 is arranged, which is designed as a head 16. The head 16 has, for example, a hexagon shape on which a hexagon key can be placed, with which the locking device 10 can be rotated. The head 16 is formed on its underside as a bearing surface 17, which is located on the shoulder 7 between the bore 5 and the enlarged bore portion 6.

Am Innenflansch 3 des Rahmens 1 sind zwei Führungskulissen 20 angeordnet, welche, wie aus der Nebenfigur a) ersichtlich ist, eine geneigte Flanke 21 aufweisen. Am Ende der geneigten Flanke 21 ist eine Rastausnehmung 22 vorgesehen, in welche in der Schliessstellung der Verriegelungsvorrichtung 10 der Arm 12 einrastet. Wie aus Fig. 1 ersichtlich ist, werden die Arme 12 bei ihrer Drehbewegung längs der geneigten Flanke 21 elastisch gebogen, und üben damit eine Vorspannkraft auf den Deckel 2 aus; der Deckel 2 wird dadurch unverrückbar auf den Innenflansch 3 gepresst, so dass er selbst bei Belastung durch stark wechselnde Lasten nicht aus seiner Lage bewegt wird. Sind mehr als zwei Arme 12 als Schliessglied 11 vorgesehen, vermehrt sich auch die Zahl der Führungskulissen 20; für jeden Arm 12 ist eine Führungskulisse 20 vorzusehen.On the inner flange 3 of the frame 1, two guide links 20 are arranged which, as can be seen from the secondary figure a), have an inclined flank 21. At the end of the inclined flank 21, a latching recess 22 is provided, into which the arm 12 engages when the locking device 10 is in the closed position. As can be seen from FIG. 1, the arms 12 are elastically bent during their rotational movement along the inclined flank 21, and thus exert a prestressing force on the cover 2; the cover 2 is thereby immovably pressed onto the inner flange 3, so that it is not moved out of its position even when loaded by strongly changing loads. If more than two arms 12 are provided as the closing member 11, the number of guide links 20 also increases; a guide link 20 is to be provided for each arm 12.

In Fig. 1 weist die aus dem Rahmen 1 und dem Deckel 2 gebildete Abdeckung einen verhältnismässig kleinen Durchmesser auf. Aus diesem Grunde kann mit einer einzigen Verriegelungsvorrichtung 10 das Anpressen des Deckels 2 auf den Innenflansch 3 erreicht werden.In Fig. 1, the cover formed from the frame 1 and the cover 2 has a relatively small diameter. For this reason, the pressing of the cover 2 onto the inner flange 3 can be achieved with a single locking device 10.

In Fig. 2 ist ein Deckel 2 mit einer verhältnismässig grossen Fläche dargestellt, wie dies für Schächte sowie für Ein- und Ausstiegsöffnungen erforderlich ist. In diesem Fall werden zweckmässig, d.h. je nach der Grösse des Deckels, drei, vier oder mehr Verriegelungsvorrichtungen 10 vorgesehen. Von diesen sind in Fig. 2 zwei Verriegelungsvorrichtungen 10 dargestellt. Sie sind genau gleich wie die Verriegelungsvorichtung 10 nach Fig. 1 ausgebildet, weshalb sie nicht mehr im Detail beschrieben werden. Die Arme 12 des Schliessgliedes 11 werden ebenfalls in den Führungskulissen 20 elastisch biegeverformt. Ein Unterschied bei dieser Ausführungsform besteht darin, dass nicht alle Arme 12 am Innenflansch 3 abgestützt sind, wie dies bei der Ausführungsform nach Fig. 1 der Fall ist, sondern ein Teil der Arme stützt sich auf Führungskulissen 20 ab, die auf der Innenseite des Deckels 2 angeformt sind. Aber auch in diesem Fall wird das Anpressen des Deckels auf dem Innenflansch 3 zuverlässig erreicht.In Fig. 2, a cover 2 is shown with a relatively large area, as is necessary for shafts and for entry and exit openings. In this case, depending on the size of the lid, three, four or more locking devices 10 are provided. Two of these locking devices 10 are shown in FIG. 2. They are designed exactly the same as the locking device 10 according to FIG. 1, which is why they are no longer described in detail. The arms 12 of the closing member 11 are also elastically bent in the guide slots 20. A difference in this embodiment is that not all of the arms 12 are supported on the inner flange 3, as is the case in the embodiment according to FIG. 1, but a part of the arms is supported on guide links 20 which are on the inside of the cover 2 are molded. But even in this case, the pressing of the lid on the inner flange 3 is reliably achieved.

In Fig. 3 ist eine zweite Ausführungsform 25 einer Verriegelungsvorrichtung dargestellt. Anstelle gerader Arme werden Arme 24 in Form einer Windung vorgesehen, deren Enden an einer Führungskulisse 30 des Innenflansches 3 geführt werden. Die Führungskulisse 30 ist als eine innenumfangsseitige Ringfläche mit einem kleinerwerdenden Durchmesser ausgebildet. Dies bedeutet, dass beim Drehen der Verriegelungsvorrichtung 25 in ihre Schliesslage die Arme 24 des Schliessgliedes 26 zusammengedrückt und dadurch elastisch verformt werden. Auch in diesem Fall entsteht in der Verriegelungsvorrichtung 25 eine Vorspannung, mit welcher der Deckel 2 im Rahmen 1 gehalten wird. In der Endstellung, d. h. in der Schliessstellung der Verriegelungsvorrichtung rasten die Arme 24 ebenfalls in eine Rastausnehmung 32 ein, siehe die Nebenfigur b) von Fig. 3.FIG. 3 shows a second embodiment 25 of a locking device. Instead of straight arms, arms 24 are provided in the form of a turn, the ends of which are guided on a guide link 30 of the inner flange 3. The guide link 30 is designed as an inner circumferential ring surface with a decreasing diameter. This means that when the locking device 25 is rotated into its closed position, the arms 24 of the locking member 26 are compressed and thereby elastically deformed. In this case too, a preload is created in the locking device 25, with which the cover 2 is held in the frame 1. In the end position, i.e. H. in the closed position of the locking device, the arms 24 also snap into a locking recess 32, see the secondary figure b) of FIG. 3.

Eine dritte Ausführungsform 35 einer Verriegelungsvorrichtung ist in Fig. 5 dargestellt. Ihre Arme 34 sind im Gegensatz zu den Armen 12 und 24 in Fig. 1 und 3 gebogen und werden an einer Führungskulisse 40 geführt. In diesem Fall ist die Führungskulisse 40 so ausgebildet, dass einerseits ein Zusammenpressen der Arme 34 wie bei der Ausführungsform nach Fig. 3 und andererseits eine elastische Biegeverformung entsprechend der Ausführungsform nach Fig. 1 stattfindet. Auch bei der Ausführungsform nach Fig. 5 ist eine solche Rastausnehmung 38 vorgesehen, siehe die Nebenfigur c) von Fig. 5. Die Rastausnehmungen 22, 32, 38 der Verriegelungsvorrichtungen nach Fig. 1, 3 und 5 haben den Zweck, die Arme 12, 24, 34 nicht nur in einem Reibschluss, sondern auch in einem Formschluss zu halten, so dass das Entfernen der Verriegelungsvorrichtung aus der Schliessstellung einer gewissen Kraftanstrengung bedarf.A third embodiment 35 of a locking device is shown in FIG. 5. Your arms 34 are in contrast to the arms 12 and 24 in Fig. 1 and 3 bent and are guided on a guide link 40. In this case, the guide link 40 is designed such that, on the one hand, the arms 34 are pressed together as in the embodiment according to FIG. 3 and, on the other hand, an elastic bending deformation corresponding to the embodiment according to FIG. 1 takes place. Such a latching recess 38 is also provided in the embodiment according to FIG. 5, see the secondary figure c) of FIG. 5. The latching recesses 22, 32, 38 of the locking devices according to FIGS. 1, 3 and 5 have the purpose of the arms 12, 24, 34 not only to be held in a frictional engagement, but also in a positive engagement, so that removing the locking device from the closed position requires a certain amount of force.

In Fig. 4 ist eine ähnliche Anordnung von Verriegelungsvorrichtungen 35 wie in Fig. 2 dargestellt. Der Deckel 2 weist hierbei eine solche Grösse auf, dass die Anwendung einer einzigen Verriegelungsvorrichtung wie bei kleineren Oeffnugnen nach Fig. 1, 3 und 5 unzweckmässig wäre, da sie massiver ausgeführt werden müsste und deshalb einen grösseren Materialaufwand benötigen würde.FIG. 4 shows a similar arrangement of locking devices 35 as shown in FIG. 2. The cover 2 is of such a size that the use of a single locking device as in the case of smaller openings according to FIGS. 1, 3 and 5 would be unsuitable, since it would have to be made more solid and would therefore require a greater expenditure of material.

Anstelle der in Fig. 4 verwendeten Verriegelungsvorrichtungen 35 könnte auch Verriegelungsvorrichtungen 24 verwendet werden. Allerdings müssten dann auch die entsprechenden Führungskulissen 30 anstelle der Führungskulissen 40 verwendet werden.Instead of the locking devices 35 used in FIG. 4, locking devices 24 could also be used. However, the corresponding guide link 30 would then also have to be used instead of the guide link 40.

In allen Figuren ist der Lagerungsstab 14 mit der Lagerungs- und Betätigungsvorrichtung 15 dargestellt worden. Dies ist nicht erforderlich, sondern es könnten beispielsweise verschiedene Köpfe 16 verwendet werden, die anstelle des Aussensechskantes einen Innensechskant, einen Kreuzschlitz, einen einfachen Schraubenzieherschlitz oder einen Vierkant aufweisen könnten, siehe die Nebenfigur d) zu Fig. 6.In all figures, the storage rod 14 has been shown with the storage and actuation device 15. This is not necessary, but different heads 16 could be used, for example, which could have an internal hexagon, a cross-slot, a simple screwdriver slot or a square instead of the external hexagon, see secondary figure d) of FIG. 6.

Bei der Verriegelungsvorrichtung 10 sind die Arme 12 als gerade Stäbe ausgebildet. Jedoch könnten anstelle gerader Stäbe auch gebogene Stäbe 12 verwendet werden, deren Biegung jedoch in einer Horizontalebene liegt, siehe Fig. 6. Die Funktion der Verriegelungsvorrichtung bleibt dieselbe wie in Fig. 1.In the locking device 10, the arms 12 are designed as straight rods. However, instead of straight bars, curved bars 12 could also be used, the bending of which, however, lies in a horizontal plane, see FIG. 6. The function of the locking device remains the same as in FIG. 1.

Auch könnten bei der Verriegelungsvorrichtungen 24 und 35 die gewundenen bzw. gebogenen Arme 34 in eine Horizontalebene gelegt werden, ohne dass sich dadurch die Funktion der Verriegelungsvorrichtung 35 ändern würde. Es wäre jedoch zweckmässig, bei der Verlegung der gebogenen Arme in eine Horizontalebene die Arme so anzuordnen, dass sie eine S-Form bilden, siehe Fig. 6.In the case of the locking devices 24 and 35, the winding or curved arms 34 could also be placed in a horizontal plane without the function of the locking device 35 changing as a result. However, it would be expedient to arrange the arms in such a way that they form an S-shape when the curved arms are laid in a horizontal plane, see FIG. 6.

Selbstverständlich ist es auch möglich, den Querschnitt der Arme verschieden auszubilden, beispielsweise rund, rechteckig, quadratisch oder polygonal. Diese verschiedenen Varianten sind in der Nebenfigur e) zu Fig. 6 dargestellt.Of course, it is also possible to design the cross section of the arms differently, for example round, rectangular, square or polygonal. These different variants are shown in the secondary figure e) of FIG. 6.
