Description

  

      Schlauchdichtungsschr        aube.       Zum Abdichten kleiner Löcher in Schläu  chen,     insbesondere        Feuerwehrschläuchen,    sind  bereits Dichtungsschrauben in verschiedenen  Ausführungsformen bekannt.  



  Die einfachste Art besteht aus einer dün  nen, Platte mit Gewindestift; sie wird vom  Schlauchinnern aus durch das Loch gedrückt  und von aussen mittelst der Mutter festge  schraubt, so dass die     Platte        da.s    Loch abdeckt.  Diese     Art    der Abdichtung ist umständlich  und kann auch nur bei leeren Schläuchen  verwendet werden.  



  Eine andere bekannte     Dichtungsschraube     ist eine Schraube mit Drahtlocke, von der sich  in der     Mitte    der     Schraubenbolzen    abhebt, auf  welchem die Mutter sitzt. Die Drahtlocke  kann von aussen in den Schlauch gedreht wer  den, ist aber zu schwach, um genügend abzu  dichten und zersticht die Schläuche.  



  Diese Nachteile beseitigt die Erfindung  durch eine     neuartige        Schlauchdichtungs-          schraube.    Diese kennzeichnet sich dadurch,  dass ihr Bolzen von einem der Länge nach    mehrmals     geschlitzten.    und mit Ringkerben       versehenen    Mantel umgeben ist, der sich beim  Anziehen der     Bolzenmutter        regenschirmartig          auseinanderspreizt    und damit den Schlauch  gegen eine die schadhafte Stelle aussen     abdek-          kende        Dichtungsscheibe    presst.  



  Auf der Zeichnung ist eine beispielsweise  Ausführungsform der     Schlauchdichtungs-          schraube    nach vorliegender Erfindung in       Fig.    1 in Ansicht und in     Fig.    2 im     Längs-          schnitt    dargestellt;     Fig.    3 zeigt die Wir  kungsweise der Schraube.  



  Der Gewindebolzen<I>a,</I> dessen Kopf<I>b</I>  zwecks leichtem Einführen abgerundet oder       kegelstumpfartig    gehalten ist, ist von einem  aus geeignetem Material (Kupfer, Messing,  Aluminium und dergleichen) bestehenden,       hülsenförmigen    Mantel umgeben. Dieser be  sitzt drei Ringkerben<I>d, e, f,</I> von welchen die  Kerben d, e weiter     auseinanderstehen    als die  Kerben e, f ; die Mantelhülse ist ferner der  Länge nach bis     zum    Bund g mehrmals ge  schlitzt und damit in Streifen h geteilt.

   Vor      der     ;Schraubenmutter    i befindet sich eine  Metallplatte     1c    und unter dieser auf dem  Schlauche m die Gummi- oder dergleichen       Dichttmgsscheibe    1.  



       Aum    Ausbessern eines Schlauches, das  während des     Betriebes    vorgenommen werden  kann, wird die     :Schraube    nebst Mantel mit  dem Schraubenkopf b voran bis zur Platte l  von aussen in den :Schlauch m eingedrückt;  sodann     wird    die     Mutter    i angezogen. Durch  den     Druck    der Schraube müssen sich die       Mantelteile    bei den Kerben, da hier das  Material am     schwächsten    ist, ausbiegen.

   Da  die     Mantelteile    zwischen d und e länger sind  als die Mantelteile zwischen den Kerben e  und     f,    bilden die ersteren Teile Stützen, wäh  rend die     letzteren    den Schlauch gegen die       Dichtungsscheibe    1 drücken: Beim fortgesetz-         ten    Anziehen der Mutter     i    spreizt sich die  Mantelhülse     h    nach Art eines Regenschirm  gerüstes auseinander und     bewirkt    damit das  feste Anpressen der Scheiben<I>k, 1</I> an den  Schlauch     7n        bezw.        dessen    Abdichtung.



      Hose sealing screw. For sealing small holes in hoses, especially fire hoses, sealing screws are already known in various embodiments.



  The simplest type consists of a thin plate with a threaded pin; it is pressed through the hole from the inside of the hose and screwed tight from the outside using the nut so that the plate covers the hole. This type of seal is cumbersome and can only be used with empty hoses.



  Another known sealing screw is a screw with a wire lock, from which the screw bolt on which the nut sits, stands out in the middle. The wire lock can be turned into the hose from the outside, but it is too weak to seal sufficiently and punctures the hoses.



  The invention eliminates these disadvantages by means of a novel hose sealing screw. This is characterized by the fact that its bolt is slotted several times along its length. and is surrounded by a sheath provided with annular notches, which when the bolt nut is tightened spreads apart like an umbrella and thus presses the hose against a sealing washer that covers the damaged area on the outside.



  In the drawing, an exemplary embodiment of the hose sealing screw according to the present invention is shown in FIG. 1 in a view and in FIG. 2 in longitudinal section; Fig. 3 shows the way we act the screw.



  The threaded bolt <I> a </I> whose head <I> b </I> is rounded or truncated cone-shaped for the purpose of easy insertion is surrounded by a sleeve-shaped jacket made of suitable material (copper, brass, aluminum and the like) . This has three ring notches <I> d, e, f, </I> of which the notches d, e are further apart than the notches e, f; the jacket sleeve is also slit along the length of the collar g several times and thus divided into strips h.

   In front of the screw nut i there is a metal plate 1c and below this on the hose m the rubber or similar sealing washer 1.



       In order to repair a hose, which can be carried out during operation, the: screw and jacket are pressed into the hose m from the outside with the screw head b up to the plate l; then the mother i is tightened. Due to the pressure of the screw, the shell parts at the notches, since the material is weakest here, must bend out.

   Since the jacket parts between d and e are longer than the jacket parts between notches e and f, the former parts form supports, while the latter press the hose against the sealing washer 1: As the nut i continues to be tightened, the jacket sleeve h expands apart in the manner of an umbrella framework and thus causes the discs to be pressed firmly against the hose 7n and 7n respectively. its sealing.
