Abstract
A security grating (1) for securing store windows (2) is constituted of a mesh (3) of overlaying horizontal bars (4) and vertical bars (5). The security grating further comprises a vertical frame member (6) on each lateral edge. The frame member (6) has a recess (10) with a depth corresponding to at least half the mesh width (9) between vertical bars. Thus, the mesh can always be cut so that the outermost vertical bar is located in the recess (10). As the vertical bar (5) can be positioned at an arbitrary depth in the recess (10) there are no specific requirements for exact tolerances when mounting the security grating (1) around a window (2).
Claims15
A security grating for wall openings in a building comprising:
- a frame support to be secured to the building;
- a grating including first and second groups of intersecting bars each having a corresponding thickness, the first group of bars being substantially equally spaced apart at a selected mesh width and including end bars respectively located within one half said mesh width of respective lateral edge portions of said grating;
- a frame for connection to the frame support, said frame including at least two frame members each having an elongated recess for respectively loosely receiving the end bar of the respective lateral edge portion of the grating, each elongated recess having selected dimensions including an interior depth corresponding to half the mesh width, an interior width corresponding to the thickness of the groups of intersecting bars, and an entry opening corresponding to the thickness of the bars of the second grip of bars, thus enabling adjustment of each frame member relative to the respective lateral edge of the grate, and
- connecting means adapted to connect the frame to the frame support.
