Abstract
The cart comprises a housing containing a plurality of supports for slidable shelves and a plurality of horizontal louvers hinged to completely cover the spaces between adjacent shelves. Dust-proof seals are provided between adjacent louvers. A pair of vertical L-shaped brackets are hinged to the housing adjacent to the louvers, and the arrangement is such that the L-shaped brackets can be pivoted away from the louvers, and the louvers, when raised, can engage slots in at least one of the brackets which thus hold the louvers in the open position.
