Definitions

  • the present invention relates to a safety grid of the kind described in the introduction to Claim 1.
  • Such a safety grid is by way of example known from DE-C-1046295.
  • a roll-up safety grid which consists of a number of mutually parallel track profiles which are made of a light metal and inserted at the ends into guide rails, and of a number of bridge elements with a convex centre portion and with concave outer portions, which are of uniform width, curved towards the outside of the safety grid and being of equal lengths and arranged with the same mutual distance, and which at the ends have hinge pins embodied as beads by means of which they are swingably hinged in longitudinal - inwardly open towards the internal side - cylindrical tracks which are located at the top and bottom of the internal side of the track profile and reaching in the full length of a track profile.
  • Safety grids of this type are mounted e.g. behind the glazing in display windows of shops, and they serve to prevent thieves from gaining access to the displayed articles after the pane has been smashed.
  • the safety grid is normally rolled up on a cylindrical core in the daytime and rolled down after closing time.
  • the safety grid can be locked in the rolled-down position by a drum brake, so that it cannot be raised from the outside.
  • the glazing in front of it can be connected to an alarm system so that the alarm is set off and the police or a safety guard is called if the pane is broken. Therefore the safety grid must be transparent and at the same time obstruct access to the displayed articles for as long time as possible after the pane has been broken.
  • a safety grid which consists of a number of transparent, equally long panels, which at each end are hinged in metal rails.
  • This known safety grid is thus completely closed, but it has the drawback that it cannot be rolled up on a cylindrical core, that in the rolled-up condition it has too large outside measurements, and that some of the metal rails in the rolled-up position come to rest against the transparent panels, which may thus suffer damage.
  • each bridge element constitutes an integral part of a track profile.
  • Each track profile has a groove at the bottom, and each bridge element has a longitudinal end at the top which is swingably embedded in the groove in the track profile immediately above.
  • other elements which are produced from a transparent material, and which at the top are embodied with a groove and at the bottom with a contact surface and an elastic lobe.
  • each track profile consists of two mutually hinged parts.
  • the track profiles are assembled to form a grid by means of bridge elements, which at each end has a groove which is squeezed or slid in over a track profile. Between the bridge elements are inserted transparent, plane elements. As is clearly seen, some of the track profiles in the rolled-up position of the grid will come to rest against a bridge element between two track profiles, whereby the former and consequently the transparent elements are subjected to a bending moment and may suffer damage.
  • a safety grid which consists of a number of plane, transparent panels, which at each end are fastened in profiles embodied as hinges.
  • This known safety grid is thus completely closed, but it has the disadvantage that if it is to be capable of being rolled up, it is necessary that the individual panels are of different lengths, shortest at the end which is rolled up first, and longest at the end which is rolled up last. The grid is therefore complicated to produce and assemble.
  • the safety grid is completely closed and at the same time it can be rolled up on a cylindrical core to form a cylindrical body of a very small outside diameter. It is furthermore avoided that the transparent panels suffer damage.
  • a known roll-up safety grid consists of a number of mutually parallel track profiles 1, which at their ends are inserted into and slidable in guide rails 2 so that the grid can be moved in the vertical direction, up or down, by a not shown cylindrical roll by a tube motor in the top of the safety grid.
  • the track profiles 1 are on their interior side embodied with cylindrical tracks 3 in the full length of the track profile 1.
  • the tracks 3 have a number of swingably embedded bridge elements 4, which at their ends are embodied with hinge pins in the shape of beads 5.
  • the bridge elements 4 connect the track profiles 1 to form a coherent grid.
  • the bridge elements 4 have a uniform width and are held by cylindrical distance pieces, which are inserted into the tracks 3 with a fixed mutual distance.
  • the track profiles 1 are made of aluminium, and the bridge elements 4 may also be made of aluminium.
  • bridge elements 4a are inserted in the safety grid between the first bridge elements 4.
  • the bridge elements 4a are made from a glass-clear transparent material, preferably a polycarbonate, and they fill out the openings 6 and come to rest on and adjoin a preceding or following bridge element 4 along the edge 7 in the full length of the edge.
  • the bridge elements 4 and 4a are held in position against each other by cylindrical lock pins 8.
  • the bridge elements 4 and 4a thus combine to form a closed rim 9 between the track profiles. This rim 9 is at both ends, as shown in fig. 5, taken a distance into the guide rails 2.
  • the bridge elements 4 can be embodied with the same cross-sectional profile as the elements 4a, and they can be made of the same type of material.
  • the bridge elements 4 can have the same length as the bridge elements 4a.
  • a bridge element 4a according to the invention is embodied with a convex centre portion 10 and concave outer portions 11 which on the outside at their transition to the longitudinal beads 5, which are embodied as a part of a cylinder, have a mutual tangent t1 with the latter.
  • the inclination of this tangent v1 is less than or equal to the inclination v2 of the tangent t2 to the circular cross section in the tracks 3 at the outer edge 12 of the tracks.
  • the bridge elements 4a are of a uniform thickness t, which is less than the diameter of a bead 5.
  • a bridge element 4a with such a cross-sectional profile and produced from a transparent polycarbonate can have a great width and at the same time be impact proof.
