Definitions

  • the present invention relates to a safety grid of the kind described in the introduction to Claim 1.
  • Such safety grids are by way of example mounted behind the glazing in the display windows of shops, e.g. goldsmith's, and they are intended to prevent thieves from getting 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 is locked in the rolled-down position by a motor brake, so that it cannot be lifted 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 smashed. Therefore the safety grid must be transparent and at the same time obstruct access to the displayed articles for as long as possible after the pane has been smashed.
  • the safety grid By embodying the safety grid as described in the characterizing part of Claim 1 it is achieved that the safety grid is completely closed and thus has no openings whatsoever through which the displayed items can be fished out and through which it is possible to insert tools in order to attack either the track profiles or the bridge elements. Consequently, it is possible that the safety grid according to the invention also makes it possible to use track profiles with a smaller cross-sectional area than those used in the known safety grids.
  • the track profile can therefore be made smaller whereby the distance between the track profiles and consequently also the transparent area can be made correspondingly larger. Furthermore, it will not be necessary to reinforce the track profiles.
  • Claim 3 describes an embodiment of a safety grid according to the invention.
  • Claim 5 ensures that a bridge element made of a glass-clear transparent material, such as polycarbonate, can have a long length and at the same time be impact-proof, which gives a free choice with regard to the length of the individual bridge ele-ments, and that the safety grid is foldable in one direction, from the inside and outwards, so that it can be rolled up on a roll, but not in the opposite direction.
  • a bridge element made of a glass-clear transparent material such as polycarbonate
  • a known roll-up safety grid consists of a number of mutually parallel track profiles 1, which at their ends are inserted into and can slide 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 (gripping rims).
  • 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 definite mutual distance.
  • the track profiles 1 are made of aluminium, and the bridge elements 4 may also be made of aluminium. Between the bridge elements 4 there are openings 6 through which the exhibited objects behind the safety grid can be viewed.
  • bridge elements 41 are inserted between the bridge elements 4. They are made from a glass-clear transparent material, preferably of a polycarbonate, which fills out the openings 6 and rest against and join up to a preceding or following bridge element 4 along the edge 7 along the full length of the edge. As shown in fig 6 the bridge elements are held in position against each other by cylindrical lock pins 8. The bridge elements 4 and 41 thus combine to form a closed rim 9 between the track profiles. This rim 9 is at both ends, as shown in fig. 6, taken a distance into the guide rails 2.
  • the bridge elements 4 and 41 preferably have the same cross-sectional profile and they can be made of the same type of material.
  • the bridge elements 4 have the same length as the bridge elements 41.
  • a bridge element 41 according to the invention is on the outside embodied with a convex centre portion 10 and with a concave outer portions 11 which, where they transform into a bead 5, have a mutual tangent t1.
  • 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 41 preferably have a uniform thickness t, which is less than the diameter of a bead 5.
  • a bridge element 41 with such a cross-sectional profile and produced from a transparent polycarbonate can have a great length and at the same time be impact proof. It can, for instance, as shown in fig. 5 have approximately the same length as a track profile 1.
