Definitions

  • the invention relates to a holder for screws according to the preamble of the main claim.
  • Field of application of the invention is the suspension of slats for substructures on ceilings.
  • the slats must be aligned very precisely horizontally.
  • Several screws are required to hold each slat, which engage in plugs that are inserted in the cover.
  • the horizontal alignment of the slats requires shims, since if the screws are only partially screwed into the respective dowels, the slat remains displaceable on the screw shafts, unless this is excluded by shims.
  • the screws can easily fall out of the slat during assembly.
  • the same problems occur with the exact alignment of plates or the like which are to be fastened at a small distance from ceilings or walls.
  • the invention has for its object a holding To create for screws that hold the screws in the passages of the crossbar in the axial direction, so that the crossbar can be aligned by changing the screwing depth and is immovable in any position on the screw.
  • the securing element secures the screws against axial displacement, but the screws can be rotated together with the securing element, so that the desired distance from the wall can be produced exactly by turning the screw accordingly.
  • the crossbar cannot be moved relative to the respective screw, so that the crossbar is always in a stable position, even if the screw is only partially screwed into the dowel and there is a gap between the crossbar and the ceiling or wall. This provides a stable substructure, for example for suspended ceilings.
  • the alignment of the bar is simply done by 'ent Schwarzen ⁇ of screwing or unscrewing the screw, are without further auxiliaries required. You can easily handle the slat together with the screws during assembly, since the screws cannot fall out of the holder.
  • the securing element is a securing ring, which is integrally connected to an assembly part via a predetermined breaking point, and that the assembly part is connected to the sleeve in a rotationally fixed manner.
  • the screw thread first cuts through the locking ring until the screw head comes into contact. If the screw is then screwed in further, this causes the non-rotatably arranged locking ring in the direction Screw head is pulled until it tears off the magnetic part. After tearing off, the locking ring is freely rotatably supported between the mounting part and an inner flange and is at the same time clamped onto the thread of the screw. The desired adjustment can now be made.
  • the mounting part initially holds the retaining ring at a small distance from the internal flange. This distance is dimensioned such that the retaining ring can be torn off the assembly part without hindrance by screwing in the screw. If the assembly part and the locking ring connected to it consist of a hard, relatively inelastic plastic material, then a smaller clearance between the locking ring and the inner flange is sufficient so that the locking ring can be torn off without hindrance.
  • the mounting part can be positively connected to the sleeve and / or glued or welded.
  • the securing element can also be designed as a helical compression spring which is inserted into the sleeve and tightly encloses the helical windings.
  • the pitch of the helical compression spring can correspond to the pitch of the screw.
  • the sleeve which receives the securing element can be inserted into the passage of the crossbar either from the rear of the crossbar or from the front side facing the screw head. It is particularly advantageous to insert the sleeve from the front into the passage of the slat, since this makes assembly easier.
  • the sleeve can have annular projections or the like on its outer wall have as clamping elements so that the sleeve is self-clamping in the passage of the crossbar.
  • the sleeve rests on the crossbar with an annular disk.
  • a washer designed according to the head shape of the screw can form the stop for the screw head, provided that the outside diameter of the screw head is larger than the diameter of the bushing in the area of the screw head.
  • FIG. 1 shows a bracket with helical compression spring inserted into a slat, in section
  • FIG. 2 shows the bottom view of a holder
  • FIG. 3 shows the holder shown in FIG. 2 in section with a helical compression spring
  • FIG. 4 shows an exploded view of a holder with an insert with an annular securing element in section
  • FIG. 5 shows the insert shown in FIG. 4 from above
  • Figure 6 shows the part of Figure 4, which receives the insert, from above and
  • FIG. 7 shows a section of a holding part inserted from the side facing the screw head into the passage of a slat.
  • FIG. 1 shows in section a slat 1, which is provided for suspending a substructure and is located at a slight distance from a ceiling 2.
  • the crossbar 1 is provided with passages, of which a passage 3 is shown.
  • a sleeve 4 has an annular disc 5, which rests on the crossbar 1.
  • an inner flange 6 projects into the inner space of the sleeve 4, so that the inner wall of the sleeve 4 is set back relative to the inner flange 6.
  • the sleeve 4 receives a helical compression spring 7 with a few screw threads, which is supported on the inner flange 6.
  • the sleeve 4 can be inserted into the passage in the manner shown.
  • a screw 8 can be screwed into the sleeve 4, the helical compression spring 7 engaging in the thread as a securing element.
  • This securing element secures the screw 8 against axial displacement within the crossbar, so that the screw 8 is securely held within the sleeve 4 in the position shown.
  • the thread of the screw 8 is only shown in sections here for the sake of simplicity.
  • the front end of the screw 8 is only shown in sections here for the sake of simplicity.
  • Screw 8 engages in a dowel 9, which is inserted into a hole 10 in the ceiling 2.
  • the depth of the borehole must be such that the desired height compensation can be carried out by screwing the screw 8 more or less deeply. In any case, it should be ensured that the screw 8 is inserted at least as far into the dowel 9 as shown in the drawing.
  • a shim is also disc 11 according to the Kop 'fform seen vor ⁇ of the screw 8, so that the screw head of the screw is held securely in the illustrated position.
  • the diameter of the sleeve can also be made smaller and the screw head correspondingly larger, so that the washer 11 can be dispensed with.
  • the washer is also not necessary if the passage 3 has a correspondingly enlarged diameter only in the area of the sleeve.
  • the screw 8 is held in the crossbar 1 by the helical compression spring 7, so that after the preassembly of several screws, these cannot fall out when attached to the ceiling.
  • the screws 8 are screwed into the associated dowels until the slat 1 is held horizontally on the ceiling.
  • a precise horizontal alignment of the substructure can be carried out by screwing in or unscrewing the screws 8. Unevenness in the ceiling can also be compensated for.
  • an 8 mm concrete dowel 9 can be used, into which a screw 8 of dimension 5 mm engages.
  • the sleeve 4 and the compression spring 7 are then adapted accordingly.
  • FIG. 2 shows a bottom view and FIG. 3 shows a section of the holder with helical compression spring shown in FIG.
  • FIG. 4 Another embodiment is shown in FIG. 4, in which a safety ring 12 is used as the securing element, which is integrally connected to a mounting part 13.
  • the mounting part 13 and the locking ring 12 form an insert 14 which is inserted into the sleeve 15 from above.
  • the design of the sleeve 15 essentially corresponds to that of FIGS. 1 to 3, but a recess 17 is provided in the annular disc 16, into which the outer flange 18 of the insert 14 engages in a form-fitting manner.
  • the shape of this recess 17 and the shape of the correspondingly designed outer flange 18 can be seen from FIGS. 5 and 6, each of which shows the top view of these two parts.
  • the insert 14 is held in the sleeve 15 in a manner fixed against relative rotation by the corresponding shape of the outer bottle 18 and the recess 17.
  • the cylindrical part of the assembly part 13 can additionally be held in a self-clamping manner on the inner wall of the sleeve 15, while the retaining ring 12 has a slightly smaller outer diameter so that it does not become stuck inside the sleeve 15.
  • a screw 8 as shown in FIG. 1, can be screwed in from below.
  • the screw thread cuts into the locking ring 12 until the screw head bears firmly against the crossbar 1 or the washer 11.
  • the locking ring 12 which is initially still mounted in a rotationally fixed manner, is pulled in the direction of the screw head until the locking ring 12 tears off the mounting part 13.
  • the locking ring 12 is rotatably mounted between the assembly part and the inner flange 19 and is firmly seated on the screw thread.
  • FIG. 7 Another embodiment of the invention is shown in FIG. 7 shown.
  • This holder is inserted into the passage of the crossbar 1 or a corresponding element from the side facing the screw head.
  • the outer wall of the sleeve 21, which is provided with clamping elements 20, is clamped firmly in the passage 3.
  • Annular projections or scale-like elements can serve as clamping elements 20.
  • the holder is pressed or driven into the passage 3 in the direction of the arrow a and the screw is then screwed in in the same direction, cutting into the annular securing element 22.
  • the securing element 22, like the securing element 12 shown in FIG. 4, is connected to a mounting part 23 via a predetermined breaking point, so that the securing element 22 tears off the mounting part 23 when there is a corresponding tensile load.
  • the mounting part 23 is rotatably inserted in the sleeve 21 and can also be glued or welded to it.
  • the holder shown in FIG. 7 is particularly easy to assemble, since assembly takes place from the front and no additional washers are required.
