Definitions

  • the invention relates to a dowel for fastening objects to components, in particular to plasterboard, with an expandable dowel body which has an inner bore for screwing in a fastening screw.
  • the invention further relates to a method for the manufacture of a dowel with an internal bore and an internal thread.
  • a dowel for attaching objects to panels or cavities having components with an inner bore for screwing in a fastening screw is known, which is also said to be suitable for plasterboard panels.
  • the dowel is divided into two parts at its rear end by a slot m and has at its front end on the insertion side, when the dowel is pushed through a borehole, radially resilient wings engaging behind the plate or the end wall of the cavity.
  • This dowel has the disadvantage that to insert the dowel m the borehole must first be opened by the resilient wings. For this purpose, the plug must be rotated at the same time when it is inserted. On the one hand this is cumbersome and on the other hand there is a risk that the borehole will be damaged. It is also practically impossible to pull the dowel out again. It must therefore be pushed in through the borehole for removal, which likewise leads to damage to the borehole. Furthermore, this dowel, like other known dowels, has the disadvantage that the borehole can break out to the rear - towards the object to be fastened - when the plasterboard building boards are subjected to greater loads. Furthermore, its resilient area is relatively long, so that a corresponding deep space is required behind the plate. Because of its length, the well-known dowel is therefore also unsuitable for blind bores.
  • the object of the present invention is therefore to improve a dowel so that it is highly resilient, easy to assemble and also removable.
  • the dowel should also not damage the component surrounding it and in particular should also be suitable for gypsum plasterboard.
  • the dubble body is divided into at least two head segments in an upstream front area by slots emanating from a front end and has a circumferential constriction in the front area on its lateral surface and in that the dubble body at its front end ⁇ turned rear end has a stop plate extending transversely to a double longitudinal axis.
  • This dowel has the advantage that it is easy to assemble, since its head segments only spread open and, as it were, reach behind the component as a tooth when the fastening screw is screwed in to a certain depth. After at least partially unscrewing the fastening screw, the dowel can be removed from the borehole again without damaging the borehole.
  • the stop plate advantageously ensures that forces are derived from the stop plate and that the borehole does not break out despite high loads.
  • the head segments like the entire dowel, can also have a relatively short overall length. This dowel can therefore be used in blind holes without difficulty and can therefore be used universally.
  • the dowel body has on its inner bore a recess lying in front of the stop plate, in which an insert with a thread is arranged.
  • Another object of the invention is to find a method for producing a dowel with an inner bore and an inner thread, with which such a dowel can be produced in a simple manner.
  • the dowel is manufactured from two vertical halves with a recess for use with the internal thread, the first half of the insert being inserted and the second half being connected to the first half.
  • the dowel body can be produced by injection molding, preferably from plastic, without having to cut a thread in the dowel. It is also not necessary to insert the insert into the injection mold before spraying.
  • the design of the dowel body in two halves makes it particularly easy to insert the insert.
  • the two halves of the dowel body are connected to one another on one long side in such a way that they can simply be folded together with the connection point as the fulcrum after insertion of the insert and are secured, for example, by a ring to be pushed over the dubble body.

  • Figure 8 is a side view of a dowel and assembled in a building board
  • FIG. 9 a side view of an anchor mounted in a blind bore of a component.
  • An anchor consists of a dowel body (1,1 ', l'') and an insert (2) with thread.
  • the dowel body (1, 1 ', 1' has a front area (3) on the discharge side with a front end (4).
  • the slots (5, 5 ', 5'') extending from the front end (4)
  • the front area (3) is divided into head segments (6, 6 ', 6 ").
  • a cone-shaped constriction (7) is arranged in the front area (3) of the dowel body (1, 1', 1") Due to the constriction (7), the head segments (6, 6 ', 6'') form a type of tooth which, with its flat surface (8) facing away from the front end (4), the dubbing body (1,1 ', 1' * surrounding, for example as a gypsum plasterboard (10 / trained component (9).

  • the head segments (6, 6 ', 6'') with deformation are pressed by the fastening screw (17 ⁇ against the wall of the blind bore (11), so that the Du ⁇ belkorper (1,1', 1 '') is an interference fit in the component (9 ').
  • the dowel body (1, 1 ', 1' ') has a stop plate (13, 13 ", 13' ') which bears against the component (9, 9'
  • the stop plate (13, 13 ') has two parallel flats (14), the spacing of which is approximately the diameter of a component (9, 9', 9 'into a borehole (18, 18')
  • the Dubelkorper has an inner bore (19, 19 ''), which closes or closes at its front end (3) facing the front end.
  • the front end of the inner bore (19, 19 ') can be frustoconical or hemispherical.
  • two transverse bores (22) extending transversely to the double longitudinal axis (21) can also be arranged as the front end of the inner bore (19, 19').
  • the front end of the inner bore (19, 19 ') is pressed apart by screwing in a fastening screw (17), so that the dowel body (1,1', 1 '') expands its front area (3 /.
