Definitions

  • the invention relates to a screen covering with screen elements arranged side by side, which are attached to profiles, a supporting substructure by additional plastic profiles that hold two lateral edges of adjacent screen elements, run parallel above the profiles of the substructure and have projections on their underside, which on the profiles of the Substructure are fastened in a latching manner, the plastic profiles having vertical openings in the center at intervals, into which bolts can be inserted from above and the openings coaxially penetrate the projections and extend into the profiles of the substructure.
  • Such a screen covering is known from DE-OS 2 736 662.
  • the head of the bolt protrudes beyond the screen covering so that it is exposed to increased wear. It can also happen with this known screen covering that the fastening openings in the substructure are knocked out, so that a secure hold is no longer guaranteed.
  • the object of the invention is to improve a screen covering of the type mentioned in such a way that the bolts do not wear out and a secure hold is provided even with enlarged openings in the substructure.
  • This object is achieved in that the head of the pin forms a portion of that area of the plastic profile that holds two lateral edges of adjacent screen elements.
  • the head of the bolt fits into the plastic profile without forming a protrusion so that it is not exposed to increased wear.
  • the screenings are also not stopped by the head.
  • the area of the plastic profile that lies in the opening of the substructure is expanded by the shaft of the bolt that snaps into the plastic profile, so that the plastic profile is held securely even when the openings of the substructure are knocked out.
  • this construction leads to the advantage that the bolts are self-tightening, so that the gap is filled when there is play.
  • the bolt head forms a horizontal profile section of the upper plastic profile area and the plastic profile is cut out accordingly at this point. As a result, the bolt head fits into the plastic profile, especially if it is of sufficient size.
  • a particularly simple and secure attachment is achieved when the shaft wall of the bolt is sawtooth-shaped.
  • the opening can have a sawtooth-shaped wall corresponding to the bolt shaft wall.
  • the opening and / or the bolt shaft be conically shaped.
  • a secure and simple fastening of the sieve elements by the bolt head is achieved in that the partially profiled bolt head has a mushroom-shaped cross section. It is particularly advantageous if the bolt is made of plastic.
  • a sieve bottom is composed of individual rectangular sieve elements 1, which consist of plastic. These sieve elements 1 have on their lateral end faces 2 groove-shaped longitudinal recesses 3, which are held by the upper area 4 of a plastic profile 5. For this purpose, the upper region 4 is mushroom-shaped in cross section.
  • the plastic profile 5 lies on the top of L-shaped horizontal metal profiles 6 of the substructure.
  • the profiles 5 run parallel to the profiles 6 and have pin-shaped cylindrical projections 7 on their underside, which are inserted into bores or openings 8 of the profile 6.
  • Each projection has in the middle an opening 9 perpendicularly crossing it, which tapers conically downwards and the wall of which is sawtooth-shaped.
  • a bolt can be inserted into the opening 9 from above, the approximately cylindrical shaft 11 of which is sawtooth-shaped on the outside in order to be able to engage in the sawtooth-shaped wall of the opening 9 and to hold it in a form-fitting manner. Since the opening 9 is tapered downwards, the degree of expansion of the projection 7 depends on the depth of insertion of the bolt 10.
  • the bolt 10 has a head 12 on its upper side, which is a portion of the upper mushroom-shaped region 4 of the Profile 5 corresponds in shape.
  • the profile 5 has a rectangular recess 13 in the upper region above the opening 9, which the head 12 completely fills out after the bolt 10 has been inserted.
  • the bolt 10 is preferably made of the same plastic material as the profile 5.
  • the shaft 11 of the bolt 10 can taper conically downwards.
  • the head 12 can also have a sawtooth shape in order to engage in a corresponding sawtooth-shaped longitudinal recess on the end face of the sieve element 1.
