  Schlagfreie, in den Ecken gelagerte viereckige Schachtabdeckung 
Das Patent Nr.   198203 betrifft eine.   schlagfreie, in den Ecken gelagerte viereckige Schachtabdekkung, bei welcher zwei an einer Kante liegende Auflagerflächen in einer gemeinsamen Bbene liegen, wogegen die beiden andern Lagerflächen gegeneinander geneigt sind. 



   Die vorliegende Erfindung hat es sich nun zur Aufgabe gestellt, den Gegenstand des Patentes Nr. 198203 weiter zu verbessern und erreicht dies erfindungsgemäss dadurch, dass die Ecken der öffnung des äusseren Rahmens der Schachtabdeckung abgeschnitten und die Lagerflächen in diesen Ecken vorgesehen sind. 



   Diese Massnahme bewirkt, dass sich der Deckel um eine gedachte lotrechte Achse etwa in der Deckelmitte in seine Ruhelage dreht, und dass die Herstellung der Schlagfreiheit zufolge der geringen zurückzulegenden Ausgleichswege rascher als bisher erfolgt. 



   Weitere Einzelheiten, Merkmale und Vorteile der Erfindung werden nachstehend an Hand eines auf der Zeichnung dargestellten Strassenablaufes näher erläutert. 



   Die Fig. 1 zeigt in Draufsicht ein Ausführungbeispiel gemäss der Erfindung, die Fig. 2 einen Schnitt längs der Linie   Il-Il   und die Fig. 3 einen Schnitt längs der Linie   III-III   in Fig. 1. 



   Der äussere Rahmen 1 der Schachtabdeckung weist eine im wesentlichen viereckige öffnung auf, deren Ecken eben abgeschnitten sind. In be- nachbarten Ecken der öffnung 2 sind Auflagerflächen 3 vorgesehen, die in einer gemeinsamen Ebene liegen. Die diesen ebenen Auflagerflächen gegenüberliegenden Lagerflächen 4 sind gegeneinander geneigt. Die Lagerflächen 3 und 4 tragen einen   Deckel   welcher die öffnung abdeckt. Entsprechend der Ausbildung der abgeschnittenen Ecken 6 im Grundrahmen 1 ist auch der Deckel 5 an seinen Ecken ausgebildet, so dass lediglich ein schmaler Spalt zwischen dem Rahmen   1   und dem Deckel 5 in den Ecken verbleibt. 



   Die erfindungsgemässen Massnahmen erlauben es nun dem Deckel, falls zwischen den Auflagerflächen 3 bzw. 4 ein Fremdkörper zu liegen kommt, durch   selbsttätige   Drehung um eine gedachte lotrechte Achse In eine schlagfreie Lage zu gelangen. Weiters wird die Anbringung eines Dekkelscharnieres erübrigt.

  Impact-free, square manhole cover mounted in the corners
Patent No. 198203 relates to one. Impact-free, square shaft cover mounted in the corners, in which two bearing surfaces lying on one edge lie in a common plane, whereas the other two bearing surfaces are inclined towards each other.



   The present invention has set itself the task of further improving the subject matter of patent no. 198203 and achieves this according to the invention in that the corners of the opening of the outer frame of the manhole cover are cut off and the bearing surfaces are provided in these corners.



   This measure has the effect that the cover rotates about an imaginary vertical axis approximately in the middle of the cover into its rest position, and that the production of the freedom from knocking takes place faster than before due to the small compensating distances to be covered.



   Further details, features and advantages of the invention are explained in more detail below with reference to a road sequence shown in the drawing.



   1 shows a plan view of an embodiment according to the invention, FIG. 2 shows a section along the line II-II and FIG. 3 shows a section along the line III-III in FIG.



   The outer frame 1 of the manhole cover has an essentially square opening, the corners of which are cut off. In adjacent corners of the opening 2, support surfaces 3 are provided which lie in a common plane. The bearing surfaces 4 lying opposite these flat bearing surfaces are inclined towards one another. The bearing surfaces 3 and 4 have a cover which covers the opening. Corresponding to the design of the cut corners 6 in the base frame 1, the cover 5 is also formed at its corners, so that only a narrow gap remains between the frame 1 and the cover 5 in the corners.



   The measures according to the invention now allow the cover, if a foreign body comes to lie between the bearing surfaces 3 or 4, to move into an impact-free position by automatic rotation about an imaginary vertical axis. Furthermore, there is no need to attach a lid hinge.
