Definitions

  • the present invention relates to a shutter-like cover for mounting pits, consisting of a plurality paralleller support beams, which rest with arranged at their front ends rollers on rails at the pit edge and are connected to each other like a hinge chain, wherein the hinge chain-like connection is made by frontally arranged on the support bar chain link plates.
  • Such a cover is known, for example from the EP 1 849 935 A2 .
  • the longitudinal guidance of the supporting beams that is to say the support of the same, transversely to the direction of movement of the cover formed by the supporting beams, would need to be improved. Accordingly, there is a risk that the cover runs obliquely to the rails and at worst clamps and blocks. This danger exists in particular when the cover is pushed into the pit cover position.
  • the present invention is therefore an object of the invention to provide a roller shutter-like cover of the type mentioned, which is easily and without risk of jamming from the covering position in the pit open position and vice versa movable.
  • the cover according to the invention should be characterized by minimal material costs.
  • the link plates are about 5 to 10 mm, in particular about 8 mm down. This ensures a secure longitudinal guidance of the cover in any case, even in a push operation.
  • the chain link plates are preferably made of steel, in particular stainless steel,
  • the support beams themselves are made of plastic or light metal, especially aluminum.
  • the support beams are formed by extruded hollow profile sections. These are reinforced in a conventional manner by transverse webs. Of particular importance, however, is a reinforcement by rods or preferably tubes which extend through sleeve-like profile sections of each supporting beam. These reinforcing rods or tubes are dimensioned so that they each protrude frontally over the support beams and define axle sections for the rollers assigned to each support beam.
  • the reinforcing means have a dual function, namely the function of reinforcing the support beams on the one hand, and the function of defining axle sections for castors, on the other hand. Due to the reinforcement by means of rods, pipes od. Like.
  • the support beams can be made very thin even with the result of a significantly lower cost of materials compared to the prior art.
  • the stringers are built accordingly easy.
  • the overall construction is considerably easier compared to the prior art, with the result that even lower-power drives for the blind-like cover can be used.
  • the compact design contributes, if the chain link plates are each positioned between support beams and rollers.
  • the mentioned reinforcing rods or tubes may be made of plastic or light metal, in particular aluminum.
  • each n-th, in particular of each 8th, 10th or 12th support beam at least one support roller spaced therefrom is arranged, which is parallel with a below the pit edge to cooperating support rail cooperates such that in the process of covering in the open position accumulate the aforementioned support rollers on the support rail, so that the corresponding portion of the cover is meanderingly held by the support rail hanging down within a storage area in the mounting pit.
  • two spaced support rollers are arranged on the underside of each n-th support beam, in each case near a support beam end face.
  • the support rollers are rotatably mounted in a specific embodiment in each case at the free ends of a support arm.
  • the wall thickness of the support beams is - as stated above in comparison to the prior art - relatively low. It is between 3.5 mm and 6.0 mm, preferably about 4.5 to 5.0 mm. Despite this low wall thickness, the carrying capacity is ensured, not only due to the usual transverse webs in the hollow profile, but in particular due to the additionally provided reinforcement by means of reinforcing rod or reinforcing tube, which extend through complementary sleeve-like profile sections of each supporting beam. These sleeve-like profile sections protrude to reinforce the hollow profile-like support beams.
  • FIGS. 1 to 6 a preferred embodiment of an inventively designed shutter-like cover 10 is shown.
  • Fig. 1 is a portion of this cover consisting of three parallel extending support beams 11, which arranged at their front ends rollers 12 on rails 13 at the pit edge 26 of a mounting pit (see also Fig. 2 ) rest.
  • the pit edge 26 is limited in the embodiment shown here by a respective circumferential U-rail.
  • This rail is in Fig. 2 designated by the reference numeral 21.
  • each have a running rail 13 is mounted on which the mentioned rollers 12 roll.
  • This longitudinal gap is in the Figures 2 and 3 designated by the reference numeral 25.
  • the width of this longitudinal gap 25 is preferably slightly smaller than the average width of a human finger, ie, between about 5 mm and 10 mm, preferably 5 mm, to avoid the pinching of fingers in this gap safely.
  • the individual support beams 11 are connected to each other like a hinge, wherein the articulated connection is effected by chain link plates 14 arranged on the front side of the support beams 11. It is in this regard in particular to the FIGS. 1 and 4 directed.
  • the chain link plates 14 project beyond the lower edge of the running surface of the rollers 12 assigned to the support beams 11 downwards. Preferably, this board is about 5 to 10 mm, in particular about 8 mm. This ensures a secure longitudinal guidance of the cover between the two rails 13 at the two pit edges 26.
  • the downwardly projecting chain link plates 14 represent a lateral stop of the support beams against the rails 13. This is an extremely compact, yet reliable construction. Jamming by tilting of support beams or the free end portion of the cover, especially when it is pushed into the pit closing position, is reliably avoided by the downwardly projecting chain link plates.
  • the support beams 11 are formed in the illustrated embodiment by extruded hollow profile sections 21.
  • these hollow profile sections made of light metal, in particular aluminum.
  • they can just as well plastic, plastic laminate, carbon-reinforced plastic od.
  • the hollow profile sections 21 are each reinforced by transverse webs 15.
  • reinforcement is provided by elongated members, such as rods or tubes 16, which extend through sleeve-like profile portions 17 of each support beam 11.
  • tubes 16 are used as reinforcing members, in particular aluminum tubes which each protrude frontally over the support beams 11 and define axle sections 18 for the rollers assigned to each support beam 11.
  • each support beam two reinforcing tubes 16 are assigned, at the ends of each of the rollers 12 are mounted. Accordingly, each support bar of a total of four rollers 12th held.
  • the axial fixation of the rollers 12 on the Achsabêten 18 takes place in a conventional manner, for example by snap rings od.
  • chain link plates 14 are positioned between the rollers 12 and the front ends of the support beams 11 .
  • These chain link plates 14 are made of wear-resistant material, in particular steel, or stainless steel. However, they can also be made of wear-resistant plastic or aluminum or the like.
  • the reinforcing rods or as here reinforcing tubes 16 may be made of plastic or steel. Preferably, however, they are made of aluminum to obtain a lightweight overall construction.
  • At least one spaced support roller 19 is arranged on the underside of each n-th, in particular of each 8th, 10th or 12th support beam 11.
  • two spaced apart support rollers 19 are provided on the underside of each n-th support beam 11, in each case near a support beam end face.
  • the support rollers 19 are each rotatably mounted at the free ends of a support arm 20, these support arms 20 extend obliquely to the underside of the associated support beam 11, in particular at an angle of about 25 ° to 35 °.
  • the support rollers 19 act with a below the pit edge parallel extending support rail (not shown here) together such that when moving the cover in the open position, the aforementioned support rollers 19 run onto the support rail, so that the corresponding portion of the cover 10 meandering from the Holding rail is suspended down within a storage area in the mounting pit. Since it is in this respect a from the EP 1 849 935 A2 is known construction, reference is made in this regard to the aforementioned document. There, the operation of the support rollers 19 is shown and explained in cooperation with the mentioned support rail.
  • each support beam 11 is associated with each support beam 11 only one single roller at each end, so that only a single reinforcing tube 16 is required.
  • the support beams 11 are then no longer guided tilt-proof on the rails 13. This construction is only suitable for very narrow rafters.
  • the illustrated embodiment with a total of four rollers per support beam is the opposite functionally reliable and above all ensures a smooth and thus stolperpark cover the mounting pit.
  • Each support beam 11 is supported on the running rails 13 so as to be stable against tilting.
  • crossbar 15 may optionally be omitted. Ultimately, this also depends on the dimensioning of the supporting beams 11.
  • the supporting beams can be made substantially more thin-walled than the supporting beams according to the prior art. This results in an overall lighter construction, which results in drives of smaller dimensions without the functional capability suffers.
