Description
Seitlich offenes Verbindungsstück mit Verschlussdeckel für Isolierrohre. Auf den seitlich offenen Verbindungs stücken mit Verschlussdeckel für Isolier rohre wurde bisher der Deckel mit Schrau ben befestigt, oder durch einen rund um den Deckel verlaufenden Rand. gehalten. Die Befestigung mittelst Schrauben ist aber teuer, umständlich und insofern auch schlecht, als die, Schrauben beim Abnehmen des Deckels leicht verloren gehen oder auch festrosten. Der geschlossene, Rand, gewähr leistet keinen festen Halt, weil er unnach giebig ist.. Der Deckel sitzt, also meist züi lose.
Durch den Gegenstand der Erfindung wird nun eine Befestigungsart des Deckels auf Verbindungsstücken geschaffen, die sich durch grosse Einfachheit und Zuverlässig keit auszeichnet. Erfindungsgemäss ist. der Deckel mit Zungen versehen, die, am Deckel angebogen sind und die bei dessen Aufsetzen sich gegen die Innenwandung des Verbindungsstückes legen und dadurch den Deckel sicher festhalten. Der Deckel kann also durch einfachen Druck aufge setzt und durch Zug an einer Seite oder Ecke abgenommen werden. Auf der Zeichnung sind! beispielsweise Ausführungsformen solcher Verbindungs stücke dargestellt.
Der Deckel a ist der Form des Anschluss- und Verbindungsstückes entsprechend ge staltet, das heisst, viereckig, rund, gebogen oder sonstwie durch Ausstanzen aus Blech hergestellt.. An zwei oder mehreren Stellen sind beim Ausstanzen Zungen b gebildet, die ungefähr senkrecht zur Deckelfläche nach einer Seite umgebogen sind. Zweck mässig sind sie etwas nach aussen geneigt und am Ende schwach einwärts gekrümmt, damit ihre Ränder beim Aufsetzen des Deckels am Rande, des: Verbindungsstückes gut anfassen. Dieser Rand ist dann, wenn .
er nicht glatt wie bei den Ausführungs formen nach Fig. 1, 2 und. 5 in die Innen wandung übergeht, an den der Zungenlage am Deckel entsprechenden Stellen mit Aus schnitten d versehen, um für die. Zungen breitere, bezw. höhere Anlageflächen zu bilden. Die Deckel sind ferner an einer oder mehreren Stellen f so geformt, da.ss sie hier über den Aussenrand des Verbindungs@- Stückes, ragen, um sie durch Untergreifen leicht abheben zu können.
Laterally open connection piece with sealing cover for insulating pipes. On the laterally open connecting pieces with cover for insulating tubes, the cover was previously fastened with screws or by an edge running around the cover. held. The fastening by means of screws is expensive, cumbersome and also bad in that the screws are easily lost or rusty when the cover is removed. The closed edge does not guarantee a firm hold because it is unyielding .. The lid sits, so mostly too loose.
By the subject matter of the invention, a type of fastening of the cover on connecting pieces is now created, which is characterized by great simplicity and reliability. According to the invention. the cover is provided with tongues which are bent on the cover and which, when it is put on, lie against the inner wall of the connecting piece and thereby hold the cover securely. The lid can be put on by simple pressure and removed by pulling on one side or corner. On the drawing are! For example, embodiments of such connecting pieces shown.
The cover a is the shape of the connecting and connecting piece according to ge, that is, square, round, curved or otherwise made by punching out of sheet metal. Tongues b are formed at two or more points during punching, which are approximately perpendicular to the cover surface are bent on one side. Appropriately, they are inclined slightly outwards and slightly curved inwards at the end, so that their edges grip the edge of the connecting piece when the cover is put on. This edge is when.
it is not smooth as in the execution forms according to Fig. 1, 2 and. 5 merges into the inner wall, at the points corresponding to the tongue position on the cover with cutouts d provided for the. Tongues wider, respectively. to form higher contact surfaces. The covers are also shaped at one or more points f so that they protrude here over the outer edge of the connecting piece so that they can be easily lifted by reaching under.
