Description
Dübel für Sehrauben. Den Gegenstand der Erfindung bildet ein Dübel für Schrauben, bestehend aus einer dünnwandigen Metallhülse, welche nach aussen vorstehende Gewindegänge aufweist, die innen- seits zur Aufnahme des Gewindes einer Schraube und aussenseits zur Verankerung der in eine Wand, Decke etc. versenkten Metallhülse dienen.
Auf der Zeichnung ist ein Ausführungs beispiel des Erfindungsgegenstandes samt Schraube teilweise im Schnitt, teilweise in Ansicht dargestellt.
Es bezeichnet 1 eine Hülse aus verhältnis mässig dünnem Blech. In die Wand der Blech hülse sind Gewindegänge 2 der zur Verwen dung bestimmten Holz- oder Metallschrauben grösse gedrückt, und zwar derart, dass die Gewindegänge aussen vorstehen. Am ge schlossenen Ende ist die Blechhülse flach zu sammengedrückt und etwas verdreht. Ist die Blechhülse in einer Wand, Decke etc. ver senkt, zum Beispiel in Gips oder Zement einge bettet, so wirken die nach aussen vorstehenden Gewindegänge, sowie das flachgedrückte Hül- senende als Verankerung und verhindern jede Bewegung der Hülse, wenn eine Schraube in dieselbe eingewindet und diese dann be lastet wird.
Die Schraube kann beliebig viele Male gelöst und wieder eingeschraubt werden, ohne dass eine Lockerung sowohl des Dübels als der Schraube zu befürchten ist.
Der beschriebene Dübel kann aus einem Blechröhrchen und dieses nahtlos oder aus schraubenförmig gewickelten Blechstreifen ge bildet und statt auf der ganzen Länge, auch nur am geschlossenen Endteil derselben mit Gewinde versehen sein. Gegenüber bisher be kannten Dübeln aus Metall, Holz usw. hat der beschriebene Dübel den Vorteil grosser Billigkeit in der Herstellung, indem er leicht aus Blechabfällen hergestellt werden kann. Ferner hat der beschriebene Dübel den Vor teil geringen Gewichtes und Raumbedarfes.
Dowels for very staves. The subject of the invention is a dowel for screws, consisting of a thin-walled metal sleeve, which has outwardly protruding threads that serve on the inside to accommodate the thread of a screw and on the outside to anchor the metal sleeve sunk into a wall, ceiling, etc.
In the drawing, an execution example of the subject invention including screw is shown partly in section, partly in view.
It denotes 1 a sleeve made of relatively moderately thin sheet metal. In the wall of the sheet metal sleeve, threads 2 of the wood or metal screws intended for use are pressed in such a way that the threads protrude from the outside. At the closed end, the sheet metal sleeve is compressed flat and twisted a little. If the sheet metal sleeve is lowered into a wall, ceiling, etc., for example embedded in plaster or cement, the outwardly protruding threads and the flattened sleeve end act as anchoring and prevent any movement of the sleeve when a screw is in it threaded and this is then loaded.
The screw can be loosened and screwed back in any number of times without fear of loosening both the dowel and the screw.
The dowel described can be made of a sheet metal tube and this seamlessly or from helically wound sheet metal strips ge and instead of the entire length, also only be provided with a thread on the closed end part thereof. Compared to previously known dowels made of metal, wood, etc., the anchor described has the advantage of great cheapness to manufacture, in that it can be easily made from sheet metal waste. Furthermore, the anchor described has the advantage of some low weight and space requirements.
