Abstract

The dowel is for insertion into a conical bore, and may consist of metal, steel or synthetic material. The dowel shank (1) is divided into four or more sections, and has a thread on the remaining part (4). It is expanded after insertion, by an expanding cone (5), and the tightening of an integral screw (6) into the cylindrical hollow (2). The screw presses the conical part of the dowel backwards into the hole, for a secure anchoring. The thread is cleared by this movement and allows the insertion of a bolt for bracket fastening.

Description

P A T E N T B E S C H R I B U N G Betr.: Dübel mit kontrollierbarer Spreizung zum Einsatz in ein konisches Dübelloch Bekannt sind Spreizdübel, die in zylindrische Bohrlöcher eingesetzt und verspannt werden. Diese Verspannung ist maßgebend für die Belastbarkeit des Dübels. P A T E N T B E S C H R I B U N G Re .: dowels with controllable Expansion for use in a conical dowel hole. Expansion anchors are known, which are used in cylindrical drill holes are used and braced. This tension is decisive for the load capacity of the anchor.

Bei vorliegender Patentanmeldung handelt es sich um einen Dübel aus Metall, Stahl oder Kunststoff mit kontrollierbarer Spreizung, der in konisch gebohrte Dübellöcher eingesetzt wird. Der Dübel kann nur zur Befestigung von Gegenständen benutzt werden, wenn die Sicherheitsspannschraube in den Spreizteilen des Dübeischaftes eingeschraubt wurde. Die Sicherheitsschraube füllt bei der Spreizung des Dübels den entstandenen Hohlraum voll aus, wobei der konisch Teil des Dübels sich parallel an die Leibung der konischen Bohrung des Dübelloches preßt.The present patent application concerns a dowel made of metal, steel or plastic with controllable expansion, which is inserted into conically drilled dowel holes. The anchor can only be used to fasten objects if the safety clamping screw has been screwed into the expansion parts of the anchor shaft. The safety screw completely fills the resulting cavity when the anchor is expanded, whereby the conical Part of the dowel is pressed parallel to the reveal of the conical bore of the dowel hole.

Figur 1 zeigt einen Dübel vor Anwendung.Figure 1 shows a dowel before use.

Der Dübelschaft (1) mit einer konischen Bohrung (2) ist in 4 oder mehrere Teile (3) aufgeschlitzt. Der nicht aufgeschlitzte Teil des Dübels hat ein Schraubgewinde (4). Der Kegel (5) ist zur Spreizung des Dübels am Ende der Dübelspreizen angeordnet. Die Spreizung geschieht durch Druck auf den-Dübelschaft (1). Nach der Spreizung wird die Sicherheitsschrsube (6) zwischen die gespreizten Teile (3) geschraubt, wobei gleichzeitig durch den Druck der Sicharheitsschraube (6) auf den Spreizkegel (5) der entstandene Kegelteil (1) des Dübels rückwärts in die konische Bohrung (2) des Dübelloches gepreßt wird.The dowel shaft (1) with a conical bore (2) is in 4 or several parts (3) slit. The part of the dowel that has not been slit has a Screw thread (4). The cone (5) is for expanding the dowel at the end of the dowel spreaders arranged. The expansion takes place by pressure on the dowel shaft (1). After Expansion, the safety screw (6) is screwed between the expanded parts (3), while at the same time by the pressure of the security screw (6) on the expansion cone (5) the resulting conical part (1) of the anchor backwards into the conical hole (2) the dowel hole is pressed.

Durch die Verlagerung der Sicherheitsschraube (6) wirdder Dübel in der Wand fest verankert und das offene Gewinde (4) für die Befestigungsschraube freigegeben.By moving the safety screw (6) the dowel is in firmly anchored to the wall and the open thread (4) for the fastening screw Approved.

Die Figur 2 zeigt einen montierten Dübel in einem konisch gebohrten Dübelloch.Figure 2 shows a mounted dowel in a conically drilled Dowel hole.

Claims (1)

PATENTANSPRÜCHE Dübel (1), gleich aus welchem Material, mit kontrollierbarer Spreizung zum Einsatz in ein konisch gebohrtes Dübelloch, dadurch gekennzeichnet, daß nach der Spreizung der Teile (3), welches über den Spreizkegel (5) geschieht, der zylindrische Hohlraum (2) durch eine bicherheitsschraube (6) ausgefüllt wird, wobei gleichzeitig der entstandene Kegelanker des Dübels (1) fest an die Leibung der konischen Dübelloch-Bohrung gepreßt wird und das vor der Montage des Dübels blockierte Gewinde (4) für die Befestigungsschraube freigibt. PATENT CLAIMS Dowel (1), regardless of material, with controllable Expansion for use in a conically drilled dowel hole, characterized in that that after the expansion of the parts (3), which happens via the expansion cone (5), the cylindrical cavity (2) is filled with a safety screw (6), at the same time the resulting conical anchor of the dowel (1) is firmly attached to the reveal the conical dowel hole is pressed before the dowel is installed releases blocked thread (4) for the fastening screw. - PATENTANSPRÜCHE -Anspruch 2, nach 1 dadurch gekennzeichnet, daß die gespreizten Teile (3) des Dübels (1) mit einem Zylinderstift oder ähnlichem Element ausgefüllt und abgesichert wird.- PATENT CLAIMS claim 2, characterized according to 1, that the spread parts (3) of the dowel (1) with a cylinder pin or the like Element is filled in and secured.
