   In dem in den Zeichnungen, vorzugsweise in Fig. 2, gezeigten deckelartigen Verschlusskörper, der keineDurchbrechungen sondern eine geschlossene Oberfläche besitzt, sind die beiden   muschelartigen Ver-     tiefungenlvbrgesehen. VondemfteienRandedermuschelartigenVertiefungen   gehen zwei einander gegen-   überliegende laschenartige Vorsprünge   2 aus, die, wie die Zeichnungen erkennen lassen. aus dem gleichen Ma-

 schlussdeckels ermöglicht. Um den Laschen 2. die erforderliche Festigkeit zu geben, sind sie konisch sich zum Muschelrand hin verbreiternd ausgebildet, wie Fig. 4 zeigt. Gleichzeitig nimmt die Stärke der Laschen 2 beim Übergang in den Rand der muschelartigen Ausnehmung 1 zu, wie Fig. 3 erkennen lässt. 



   Die erfindungsgemäss vorgesehenen laschenartigen Vorsprünge an den muschelartigen Ausnehmungen erfüllen somit die gleiche Aufgabe wie die bisher unter grösserem Herstellungs- und Kostenaufwandverwendeten eingegossenen Querstäbe. 



    PATENTANSPRÜCHE :    
1. Aus Gusseisen bestehender deckelartiger Verschlusskörper für Schachtöffnungen, beispielsweise für in der   Strassenfläche   liegende Öffnungen von Kanalisationsanlagen, Entwässerungseinrichtungen, Sinkkästen u. dgl., bei denen in der geschlossenen Oberseite des Deckels muschelartig ausgebildete Ausnehmungen für die Aushebewerkzeuge vorgesehen sind, dadurch gekennzeichnet, dass der Rand der Ausnehmungen mit zwei einander gegenüberliegenden, zungenartig vorspringenden Laschen aus dem Deckelmaterial ausgestattet ist.

  Lid-like closure body for manhole openings made of cast iron
 EMI1.1
 

 <Desc / Clms Page number 2>

 



   In the cover-like closure body shown in the drawings, preferably in FIG. 2, which has no openings but a closed surface, the two shell-like depressions are seen. Two opposing tab-like projections 2 which, as the drawings show, emanate from the rim of shell-like depressions. from the same ma-
 EMI2.1
 key cover allows. In order to give the tabs 2. the required strength, they are designed to widen conically towards the shell edge, as FIG. 4 shows. At the same time, the strength of the tabs 2 increases on the transition to the edge of the shell-like recess 1, as shown in FIG. 3.



   The tab-like projections provided according to the invention on the shell-like recesses thus fulfill the same task as the cast-in transverse rods that were previously used with greater manufacturing and cost expenditure.



    PATENT CLAIMS:
1. Made of cast iron cover-like closure body for manhole openings, for example for openings in the street surface of sewer systems, drainage systems, gullies and the like. Like., in which in the closed upper side of the lid shell-like recesses are provided for the excavation tools, characterized in that the edge of the recesses is equipped with two opposing, tongue-like protruding tabs made of the cover material.

 

Claims (1)

2. Verschlusskörper nach Anspruch 1, dadurch gekennzeichnet, dass die Laschen einen die Einbringung des Aushebewerkzeuges gestattenden Spalt bilden. 2. Closure body according to claim 1, characterized in that the tabs form a gap permitting the insertion of the extraction tool. 3.
