Definitions

  • the invention relates to a roller shutter-like cover for assembly pits, with the features of the introductory part of claim 1.
  • a similar cover in which the support beams can extend and retract telescopically and have rollers as guide bodies at their ends, is known from GB-A-2 060 754.
  • the axes of the rollers run at right angles to the support beams and are supported on vertical guide legs of the rails on the deck. The rollers cannot prevent the pushed cover from rearing up and cannot carry it along a bottom-side web section.
  • DE-U-1 940 275 describes a cover, for example for swimming pools, which is to be moved in a sliding manner, the cover being designed to be floating and requiring no special guides. A special motor drive is not described.
  • FIGS 1 and 2 show features of the invention.
  • the assembly pit 14 has rails in the double-T shape at the upper edge, which are firmly walled in.
  • the double-T rails 11 carry U-shaped rail guides 10 for the supporting beams 1, which are formed, for example, by a rectangular tube and rest with their ends on plastic supports 28 (FIG. 2).
  • the individual supporting beams 1 are fastened to the articulated chain 2 by means of angled fastening elements 21 (FIG. 2).
  • This articulated chain 2 has articulated links, the length of which is adapted to the width of the supporting beam plus the width of the gap between two articulated links.
  • the chain link 7 is in each case under this gap.
  • the pushing force for moving the cover 12 is introduced into the link chain 2 by the drive motor 4 via the upper sprocket 5 (FIG. 1).
  • a lower sprocket is designated.
  • the sprocket has corresponding recesses that act on the chain links 7.
  • the chain wheels 5 for the two link chains connecting the supporting beams are each arranged at the end of the cover when it is in the cover position. If the cover is brought into the cover position, the sprocket 5 pushes the part of the cover entering the cover position in front of it.
  • the links 24 of the joint chain are fastened to the underside of the supporting beams by means of the screws 23.
  • the chain link 7 is each formed by a pin 25 and a sleeve 26.
  • the bolt 25 carries at its end the roller 8, which rests on the underside of the rail 11.
  • This rail 11 also forms the support flange for the ends of the beams 1.
  • the plastic support 28 made of a suitable plastic with low friction is mounted on this support flange or the rail 11 by means of the screws 27.
  • the inner edge 29 of the plastic pad 28 cooperates with the outer edge 30 of the chain link 24, so that a guide of the support beam 1 is obtained in this way.
  • An angle rail limits the floor to the side of the cover of the assembly pit.
  • the rollers rest on the rail for the bar ends from below. This ensures that the rollers in the event of a possible load on the cover. especially when driving through a vehicle, do not carry the weight and are therefore exposed to a defect. This also reduces the width of the guide of the cover and there is no additional assembly effort.
