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.
