Abstract
The dustproof cabinet disclosed features a lattice framework in which a plurality of members are interconnected via their ends in sets of three, at least, by way of modular joints which, together with the members, create frames around the external openings of the lattice; each opening is then enclosed closed by a dustproof panel. The joints exhibit ribs or channels which, together with similar ribs or channels incorporated into the members, provide each frame with the mounting for a seal that occupies the entire periphery of the relative frame and offers a frontal abutment to the panel covering the relative opening.
Claims11
A dustproof cabinet for electrical equipment or the like comprising:
- a framework of substantially parallelepiped shape including a plurality of outwardly facing openings each substantially in the shape of a parallelogram;
- said framework including a plurality of joints and members with each joint having means for detachable interconnection with a plurality of said members so as to form said framework, each joint being located in the framework at a vertex of at least three of said openings;
- said cabinet further including fastener means for securing each said member removably and detachably in a respective joint;
- a plurality of panels each for mounting over a said opening, said members and joints when assembled providing for each said opening a peripheral frontal abutment for receiving a said panel;
- a mounting means extending continuously about the periphery of each said opening and carried by said members and joints so as to provide support for sealing means;
- and
- dustproof sealing means removably lodged between each said panel and said framework and engaging the entire periphery of each said panel with said respective mounting means preventing outward movement of said respective sealing means with respect of a said panel.
