Definitions

  • the invention relates to a device for attachment to a profile, in particular for fastening of fittings to hollow chamber profiles, with a particular at least two walls of the profile in perforations passing through fastening member, via which forces of the fitting part in the profile can be introduced.
  • the device can also be used for other purposes, for example as a spacer or as a cable feedthrough.
  • a device for fastening fittings is known for example from DE 202 18 699 U1.
  • the known device which for example serves to fasten bands for the hinged connections of a wing, for example a window or a door, to a stationary frame, has a mounting screw, which comprises a self-tapping external thread, so that it is perforated in the profile walls is rotatable.
  • the introduction of forces in the axial direction of the mounting screw in the profile walls via the engaged with the profile walls thread flanks.
  • the mounting screw has a radially extending beyond the external thread circumferential collar.
  • the mounting screw a central longitudinal recess, in which a arranged in the direction of insertion at the rear end internal thread and in the insertion direction at the front end a hexagon socket to attack a turning tool are provided.
  • the perforations are first incorporated in the required size in the profile. Subsequently, the mounting screw is screwed with the turning tool in the profile perforations until the abutment collar rests against the outside of the profile. Subsequently, the fitting part is screwed by means of an engaging in the internal thread of the mounting screw fixing screw.
  • the disadvantage is that the mounting screw is expensive to manufacture.
  • turning the mounting screw with too high a torque can lead to an undesired deformation of the profile walls into which the external thread of the mounting screw engages.
  • Another device for fastening fittings on a profile is known from DE 196 07 029 C1.
  • This device has a support bush which can be fixed in bores of the profile in an interference fit.
  • the interference fit is caused by widening of the support sleeve when screwing in threaded pins.
  • the advancing in the insertion direction region which extends over about two-thirds of the total length of the attachment member, has four circumferentially distributed longitudinal slots, which divide this area into four segments.
  • the internal thread of the fastening member is formed such that this area widens when screwing a fastening screw for the fitting part, which in turn an interference fit of the fastening member is achieved in the profile.
  • the portion of the attachment member which adjoins this slotted area towards the fitting part is also subdivided into four segments via four slots.
  • Each segment has latching projections into which the edge of a profile perforation can engage.
  • the invention is therefore an object of the invention to provide a device for attachment to hollow chamber profiles, which is easy to manufacture, and in particular allows a quick and easy mounting of a fitting on a multi-chamber profile.
  • the fastening member is not designed as an external thread mounting bolt, but as a fixing dowel having at least two locking projections between which a wall of the profile in the inserted state of the fixing dowel engages, can be omitted on the formation of an external thread and so the manufacturing cost be reduced.
  • the assembly is carried out by inserting the fixing plug into the prefabricated perforations. is brought.
  • larger forces can be introduced in the axial direction by means of the fastening member in the profile, as in a fastening screw designed as a mounting member. This is due to the fact that the locking lugs can engage behind the profile wall over a larger area than the flanks of a thread.
  • it has been found that only the locking lugs produce sufficiently high holding forces, so that is omitted in departure of the previous adjustment to a radial contact of the dowel on the Lochungsrad under bias.
  • the latching projections are formed on webs or tongues separated from one another in the direction of the longitudinal axis of the fastening plug.
  • the fixing plug has an internal thread and a complementary external thread fastening screw.
  • the fitting of the fitting can then be done by screwing by means of the fastening screw.
  • the fixing plug preferably has means for preventing rotation in the inserted state in the perforations of the profile.
  • These means can in principle be designed in any manner which prevents the attachment plug from rotating.
  • the means for preventing rotation comprise a force-fitting or form-fitting co-operating with the fitting part.
  • This extension can be designed in such a way that it is clamped between the fitting part and the profile when the fastening screw is screwed in, or a recess is provided in the fitting part and engages in the projection.
  • the latching projections of the fixing plug are arranged such that an end portion of the fixing plug protrudes in the mounted state from the fitting part facing wall of the profile.
  • this end region has an outer circumferential surface which engages centering in a bore of the fitting part, a positioning of the same takes place automatically when the fitting part is attached, which, for example, prevents tilting of the hinge axis in the case of a band.
  • the projection which effects the securing against rotation is arranged on the lateral surface and engages in a complementary recess on the fitting part.
  • the latching projections between which a wall of the profile engages in the inserted state of the fixing dowel, is approximately 2.5 mm in the longitudinal direction of the fixing dowel.
  • the fixing dowel is then universally applicable, since the wall thicknesses of the profiles commonly used are always less than 2.5 mm.
  • this variant of the fixing dowel is also suitable for smaller wall thicknesses, for example 1 mm, since when tightening the fastening screw the profile wall engaging behind locking projections are pulled against the same and thus a backlash-free fit of the fixing dowel is effected.
  • the distance of the locking projections in the longitudinal direction of the fixing dowel is slightly larger than that Distance between the opposite sides of two profile walls.
  • a fastening dowel formed in this way thus engages behind a profile wall with at least one latching projection and another profile wall with at least one other latching projection. Retaining forces acting in the longitudinal direction of the fastening plug are then introduced into one or the other profile wall, depending on the orientation.
  • the locking projections are arranged such that they engage behind the at least three walls.
  • the fixing plug is preferably made of plastic, in particular of glass fiber reinforced polyamide (PA66 GF), since it can be made from this material, for example by injection molding without subsequent forming or machining. Furthermore, this material is characterized by a low thermal conductivity, which prevents the formation of undesirable cold bridges.
