ABSTRACT:
A housing assembly includes a high-profile basic unit and low-profile expansion unit. The basic unit has a recessed portion on its upper surface and a pair of grooves respectively extending vertically along its opposite sidewalls. A pair of connecting members equal in length to the grooves of the basic unit are normally received into these grooves. The expansion unit is formed on its bottom surface with a base portion and a pair of grooves respectively extending vertically along its opposite sidewalls. The base portion of the expansion unit is engageable into the recessed portion of the basic unit. The grooves of both basic and expansion units have an equal width. A pair of vanity members equal in length to the grooves of the expansion unit are normally fitted into these grooves. The arrangement is such that, when the expansion unit is mounted on the basic-unit, the base portion of the expansion unit fits into the recessed portion of the basic unit and the grooves of the basic unit are aligned vertically with the grooves of the expansion unit, so that the connecting members can be engaged into the aligned grooves and fastened to the expansion unit and the basic unit and the vanity members can be engaged into the grooves of the basic unit and fastened thereto.
