Description

  

  Einschlagbare, rohrförmige, metallene     Wanddübelhülse    zur Befestigung von  Schrauben, Haken oder dergleichen in Wänden aus weichen Baustoffen.    Den bisher bekannten, einschlagbaren       Wanddübelhülsen    haftet der Nachteil an, dass  entweder eine Spreizung der Spitzen zur Er  zielung eines sicheren Haltes überhaupt nicht  möglich ist, oder, dass gezackte Enden ledig  lich eine Sicherung gegen Verdrehung, oder  infolge zu kurzer Ausführung der Zacken und  zu grosser Wandstärke der     Dübelhülse    bei  wieder andern Ausführungen keinen festen  Halt gewährleisten.

   Zum Teil wird eine Sprei  zung von zwei oder mehreren Zacken dadurch  herbeigeführt, dass die Spitzen beim Einschlagen  in weiche     Verputzwände    eine tiefer liegende       Hartsteinschicht    voraussetzen, die weiteres  Eindringen verhindert und ein     Auseinanderbie-          gen    der Zacken bewirkt. Alle diese     Dübelarten     lassen sich daher für ausgesprochen weiche  Wände, etwa aus Gips, Kalkmörtel, Lehm oder  dergleichen, nicht verwenden, da sie keinen  festen Halt ergeben und vielfach Wände und  Verputz durch Ausbrechen beschädigen.  



  Die vorliegende Erfindung beseitigt diese  Nachteile dadurch, dass eine einschlagbare,    rohrförmige, metallene     Wanddübelhülse    am  einzuschlagenden Ende     spitzeZacken    aufweist,  die sich beim Einschlagen der Hülse in wei  chen Wandbaustoff zum Zwecke festen Haltes  in radialer Richtung nach aussen     krallenför-          mig    umbiegen.  



  Das gezeichnete Ausführungsbeispiel des  Erfindungsgegenstandes weist eine rohrförmige       Dübelhülse    e     (Abb.    1) mit dünnwandigen,  schlanken Spitzen a aus Metall auf, deren  Zacken leicht gespreizt sind, so dass die Spit  zen auf einem Kreis liegen, der einen gegen  über dem Durchmesser der Hülse e um ein  geringeres grösseren Durchmesser aufweist,  damit der Richtung der Spreizung beim Ein  schlag weitestgehend Vorschub geleistet ist.  Wird diese Hülse mit den Spitzen voraus in  weichen Wandverputz, z.

   B. aus Gips, Kalk  mörtel, Lehm oder dergleichen, eingeschlagen,  so spreizen sich die Spitzen     ac    innerhalb des  Wandbaustoffes d, wie in     Abb.    2 gezeichnet,  auseinander und biegen sich in Richtung des  Hülsenhalbmessers     krallenförmig    um, wobei      das im Innern des Spitzenkreises bei b zu  sammengedrängteVolumen des Wandbaustoffes  nicht nur fördernd auf die     Ausbiegung    der  Spitzen einwirkt, sondern ausserdem noch einen  äusserst festen Sitz der Spitzen     ae    sichert.  Die     Dübelhülse    ist damit nicht nur gegen  Verdrehung, sondern auch zugleich gegen Her  ausziehen auf das Beste gesichert.

   Das Innere  der     Dübelhülse    e kann in bekannter Weise mit  Gewinde oder dergleichen versehen sein und  so zur     Aufnahme    von Schrauben, Haken, Ösen       oderdergleichendienen.        DiegrosseErweiterung     des Durchmessers der     Spitzenkrone    hat zur  Folge, dass dein Windrehen von Schrauben ein  erheblicher Widerstand entgegengesetzt ist,  wodurch einzuschraubende     Haltevorrichtungen     fest angezogen werden können.



  Impactable, tubular, metal wall dowel sleeve for fastening screws, hooks or the like in walls made of soft building materials. The previously known, knock-in wall dowel sleeves have the disadvantage that either a spreading of the tips to achieve a secure hold is not possible at all, or that jagged ends single Lich a protection against rotation, or as a result of too short execution of the prongs and too large Wall thickness of the dowel sleeve does not guarantee a firm hold in other versions.

   In some cases, two or more prongs are caused by the fact that the tips require a deeper layer of hard stone when hammering into soft plastered walls, which prevents further penetration and causes the prongs to bend apart. None of these types of dowels can therefore be used for extremely soft walls, such as those made of plaster of paris, lime mortar, clay or the like, since they do not provide a firm hold and often damage walls and plaster by breaking.



  The present invention eliminates these disadvantages in that a knock-in, tubular, metal wall dowel sleeve has pointed prongs at the end to be hammered in, which when the sleeve is hammered into soft wall building material bend outward in the radial direction with claws for the purpose of a firm hold.



  The illustrated embodiment of the subject matter of the invention has a tubular dowel sleeve e (Fig. 1) with thin-walled, slender tips a made of metal, the prongs of which are slightly spread, so that the tips lie on a circle that has a diameter of the sleeve e has a smaller larger diameter, so that the direction of the spreading is made as much as possible in the impact. If this sleeve with the tips ahead in soft plaster, z.

   B. made of plaster of paris, lime mortar, clay or the like, so the tips ac spread within the wall building material d, as shown in Fig. 2, and bend claw-shaped in the direction of the sleeve radius, with the inside of the tip circle b compressed volume of the wall building material not only has a promoting effect on the bending of the tips, but also ensures that the tips are extremely tight ae. The dowel sleeve is thus not only secured against rotation, but also at the same time against pulling out.

   The interior of the dowel sleeve e can be provided with a thread or the like in a known manner and thus serve to accommodate screws, hooks, eyes or the like. The large expansion of the diameter of the tip crown has the consequence that there is considerable resistance to the turning of screws, whereby holding devices to be screwed in can be tightened firmly.
