Modular grating for keeping insects and small animals out of light shafts in buildings, comprises base plate with ventilation holes and side walls with interlocking tabs

摘要

Each module has two pairs of tabs (1) along the top edge of each side wall, each pair comprising a horizontal tab separated by a space (2) from a vertical tab. The two horizontal tabs on a first side wall of a first module can be interlocked with the two vertical tabs on an adjacent first side wall of a second adjoining module and the two vertical tabs on the first side wall of the first module can be interlocked with the two horizontal tabs on the adjacent first side wall of the second module so that the two modules are offset with respect to each other. The side walls are arranged around a base containing ventilation holes (3).
