  • Patent number: 4894960
    Abstract: A canopy assembly has an openable panel in a top or bottom wall to allow access to the interior without disturbing the front face member. This may be required e.g. to maintain light fittings or to tension a flexible sheet of the front face member. There may be a pair of upright rear girders and an assembly at the top and/or the bottom comprising a rear transverse member that bridges the girders and has a hinge channel at the front. Brackets project forwardly from the girders and carry a front transverse member. A lid is hingedly engaged in the hinge channel and extends to the front transverse member, which also supports the front face member, a displaceable screen, and a support for light fittings.
