    Die Erfindung betrifft einen Dübel für Befestigungen an Platten, Hohlwänden und dgl. einerseits und Vollbaustoffen andererseits. Der Dübel besteht aus einem eine Längsbohrung mit Innengewinde oder Innenrippen versehenen Schaft, sowie zwei davon ausgehenden Schenkel, die über ein mit einem Flansch un Drehsicherungsmittel versehenen, ebenfalls eine Längsbohrung aufweisenden Kopfteil zusammengehalten sind. Um sowohl in Hohlwänden, insbesondere jedoch in Vollbaustoffen hohe Haltekräfte zu erzielen, bildet die Querschnittskontur der beiden Schenkel im mittleren Bereich eine Ellipse, die zum Schaft und Kopfteil hin allmählich in einen Kreis übergeht. Die beiden zueinanderweisenden Flächen der Schenkel sind durch einen Spalt getrennt, dessen lichte Weite der Differenz zwischen dem großen und kleinen Ellipsendurchmesser entspricht. Schließlich sind die Spaltflächen der Schenkel in Fortsetzung der Längsbohrung des Kopfteiles mit Längsrillen versehen.

    The invention relates to the field of mechanical engineering J, in particular to fastening elements on plates, floor walls and on walls of solid materials.
    The purpose of the invention is to increase the reliability of fastening and load capacity.
    Figure 1 shows the dowel; Fig.2 is a section A-A in Fig .; na. Z - section bb in figure 1 | on 1FIG.4 - unit of fastening the object on the plate; Fig 6 is the same to the wall | FROM solid material. The dowel contains a rod 1 with a head | 2 and a drilled threaded ring 3, the hole 3 has ribs 4. In the middle part the dowel is made in the form of two bends 5, separated by slot 6, and has cross section in the form of an ellipse. The width of the cut corresponds to the difference between the large and small diameters of the ellipse. The head 2 is made with the flange 7 bent under the ppm angle and the means b against the turner 1t in the form of the ribs of the Knee 5 are made with a variable thickened wall and with a cross section of the joint with the head and the rod
    “Eat in a circle
    To facilitate expansion in the place of the greatest thickening 9, the i | i0 thinning of the cross section is seen in the 6 view of the transverse drilled hole 10 passing in the plane of the slot 10. Another thinning of the cross section is in the zone of the joints of I t with the rod 1, perpendicular to the slot cut or cutouts 11,
    To direct the screwed Yurup 12, on the surfaces of the slot of the Knee 5, from the drilled Hole 13 of the head 2 to the aperture 3 of the rod t, longitudinal ribs Fia 14 are made.
    In order to fasten the object 15 to the plate 16, the screw 12 is screwed into the hole 3 of the rod 1f while the knees 5 50 1 | RI move the rod along the screw r and expand in the radial direction and fold. Thus, on the back of the plate 16, a yinop is formed with a large bearing surface, 55

    this ensures a secure fit even when plates are made of soft and porous materials, such as plasterboard.
    When an object is attached to the wall 17 of solid building material, the dowel is driven into a drilled hole 18, whose diameter corresponds to the diameter of the head and the rod, while the elbows 5 are compressed until their surfaces touch in the zone of greatest thickening. When screwing in the screw, the dowel expands and seizes in the wall hole. Tapered longitudinal ribs 14 are guides to the screw.
    The use of the proposed dowel allows for secure fastening in any materials.
