Abstract

Die Erfindung betrifft eine Verschlussvorrichtung zum Verschließen einer bodenseitigen Öffnung eines Schachtes, mit einem Rahmen und einem, von einer Geschlossen- in eine Offenstellung überführbaren Verschlusselement, wobei am Rahmen eine Aufnahme ausgebildet ist, die mit einer am Verschlusselement angeordneten Schwenkachse eine scharnierartige Verbindung bildet, wobei die Schwenkachse über ein Federelement am Verschlusselement befestigt ist. Das Federelement übt in der Geschlossenstellung eine Kraft zwischen Schwenkachse und Verschlusselement aus. Das Verschlusselement wird hierdurch auf der dem Federelement abgewandten Seite gegen den Rahmen gedrückt. Durch eine hieraus resultierende Reibungskraft zwischen Verschlusselement und Rahmen wird das Verschlusselement in der Geschlossenstellung fixiert und eine unbeabsichtigte Bewegung des Verschlusselementes von der Geschlossenstellung in die Offenstellung wird verhindert.

The invention relates to a closure device for closing a bottom opening of a shaft, with a frame and a, from a closed convertible into an open position closure element, wherein on the frame a receptacle is formed, which forms a hinge-like connection with an arranged on the closure element pivot axis, wherein the pivot axis is fastened via a spring element on the closure element. The spring element exerts in the closed position a force between the pivot axis and closure element. The closure element is thereby pressed against the frame on the side facing away from the spring element. By a resulting frictional force between the closure element and the frame, the closure element is fixed in the closed position and unintentional movement of the closure element from the closed position to the open position is prevented.
