Definitions

  • the invention relates to a roller shutter-like cover for assembly pits, consisting of a plurality of parallel support beams, the ends of which have guide bodies and rest on rails that serve as guides at the edge of the pit, the support beams being connected on the underside by means of chains running parallel to the rails, and can be moved from the cover position into a rest position in the pit and vice versa by a drive motor acting on the chains.
  • a roller shutter-like cover of the type described above can be found, for example, in GB-A-2 060 754.
  • the rails have guide surfaces which are arranged in vertical planes and which cooperate with rollers at the ends of the support beams which move around vertical ones Rotate axes when the cover is in the cover position.
  • the support beams are telescopic and by means of the arrangement described it is possible to cover different pit widths.
  • a plurality of deflection rollers is necessary to form the endless arrangement, which causes an additional assembly effort. With a long installation pit, it becomes difficult to divide the cover into individual parts, which is often desirable.
  • 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
  • each support beam forms a link of a joint block, the joints of which are assigned to the gaps between the support beams and are arranged in the cover position at the lower end of the column that the drive motor with its Sprocket with recesses for the chain joints on the chain during the movement in the covering position and that the guide surfaces of the guides for the guide body of the supporting beams run horizontally in the covering position.
  • the invention provides a solution of how the roller shutter-like cover can also be pushed by means of the drive motor, so that the endless arrangement, which always allows the cover to move by pulling, is avoided. It has been found that through a sensible connection of the three elements, namely the joints with the drive motor, the support of the support beams by the rails, and the guidance of the support beams, for. B. by rolling on the one hand a very resilient construction is created, and on the other hand also the fear of jamming during the sliding movement can be prevented.
  • the guides and guide bodies provided in the invention entail a comparatively small additional outlay if it is taken into account that the additional deflection devices for an endless arrangement are avoided.
  • the slidable roll-like cover for example, in two parts in the case of longer assembly pits, so that one or the other part of the pit is covered, but the other part remains accessible.
  • any sections can be kept open. In particular, guides in the middle of the pit etc. are avoided.
  • the invention also proposes that the driving sprocket is arranged as a deflection wheel between horizontal and vertical guides of the cover. This significantly simplifies the construction. In addition, the advantage is gained that the thrust is introduced by the driven sprocket in a straight line into the relevant part of the cover. This reduces any clamping forces from the outset.
  • the invention also proposes that the guides and guide bodies are arranged at such a height or distance that they do not substantially support the loaded supporting beams.
  • the guide bodies only have the task of providing adequate guidance in the deflection areas and, furthermore, of ensuring that the buckling forces which occur when pushing are absorbed.
  • each support beam has a roller at each end. It is true that several rollers can also be provided, as a result of which any tilting movement of the individual support beam is then completely ruled out. However, it is also sufficient to have a roller at each end, since the supporting beams slide on the associated guides anyway.
  • the assembly pit 14 has rails in the shape of a double T at the upper edge, which are firmly walled in.
  • the double-T rails 11 carry the U-shaped rail guides 10, which include the rollers 8.
  • the U-shaped guides are also permanently installed.
  • the axes 9 of these shafts run in the longitudinal direction of the support beams 1.
  • the height of the support 13, the arrangement of the rollers 8 with respect to the support beam 1 and the U-shaped guides 10 are selected and assigned to one another such that the guides 10 surround the rollers 8 with play, while the support beams rest on the support 13.
  • the arrangement can also be such that the rollers 8 carry a small part of the weight of the support beam 1 when the support beams are not loaded. This makes it easier to move. Since the bearing of the rollers 8 in the supporting beam 1 is somewhat flexible, it will result in the load that the load is taken over the support 13 from the rail 11.
  • rollers 8 are only slightly loaded and that it is nevertheless ensured that the cover has a high load-bearing capacity.
  • the individual supporting beams 1 are fastened to the articulated chain 2 by means of the angled fastening elements 21.
  • This articulated chain 2 has articulated links, the length of which is adapted to the width of the support beam with respect to the width of the gap 3.
  • the chain link 7 is in each case under the gap 3.
  • the thrust for moving the cover 12 is introduced by the drive motor 4 via the sprocket 5 into the link chain 2.
  • the chain wheel has corresponding recesses 6, which 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 the cover 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 guide 10 In the area of the deflections, the guide 10 has curve pieces 17 and a further deflection wheel 18. In the vertical part 19 of the guide and also in the guide part 20 on the bottom of the pit 14, a rail for the ends of the supporting beams 1 per se can be dispensed with. However, it is advisable to provide suitable rail elements, albeit of smaller dimensions, with a corresponding support, so that the sliding movement can also be mastered reliably in this area.
  • the links 24 of the articulated chain are fastened to the underside of the supporting beams by means of the screws 23.
  • the chain link 7 is each formed by the bolt 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.
  • a 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 in this way a guide of the supporting beam 1 is obtained.
  • the angle rail 31 delimits the floor to the side of the cover of the assembly pit.
  • the rollers rest on the rail for the bar ends from below. It is thereby achieved that the rollers do not carry the weight in the event of a possible load on the cover, in particular when driving through a vehicle, and are thus exposed to a defect. This also reduces the width of the guide of the cover and there is no additional assembly effort.
  • insert pieces 38 can for example consist of a well sliding plastic and are inserted into the ends of the support beam 1.
  • the insert pieces 38 can consist, for example, of an upper and a lower part 32 or 33, which leave a gap 34 between them, the gap 34 serving as a guide. In order to ensure smoothness in curves, it is advisable to limit the guiding action to the central region 35, that is to say only in this region to adapt the gap width approximately to the thickness of the guide 36.
  • the guide 36 is, for example, flange-shaped and welded to the angle rail 31. It extends both in the cover area of the pit and in the vertical part of the path of the cover or on the pit floor.
