An expandable housing assembly for electronics circuitry, comprising: a basic unit having a recessed portion on an upper surface thereof and a pair of grooves respectively extending vertically along opposite sidewalls thereof; a pair of connecting members equal in length to said grooves of the basic unit and respectively engageable thereinto; an expansion unit having a base portion on a bottom surface thereof and a pair of grooves respectively extending vertically along opposite sidewalls thereof, the base portion of the expansion unit being engageable into the recessed portion of the basic unit, the grooves of the basic unit and the grooves of the expansion unit having an equal width; and a pair of vanity members equal in length to said grooves of the expansion unit and respectively engageable thereinto, the arrangement being such that, when the expansion unit is mounted on the basic unit, said 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 said 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.
Claim 3
Dependent Claim
42 words
An expandable housing assembly as claimed in claim 1, wherein said extension unit is formed with a recessed portion on an upper surface thereof identical to the recessed portion of the basic unit for receiving the base portion of another extension unit.
Claim 4
Dependent Claim
90 words
An expandable housing assembly as claimed in claim 1, wherein the connecting members are respectively formed with flange portions, and wherein said basic unit is formed with a pair of recesses respectively adjacent to upper ends of the grooves of the basic unit and said expansion unit is formed with a pair of recesses respectively adjacent to upper ends of the grooves of the expansion unit, said flange portions being respectively engageable with the recesses of the extension unit when the connecting members are respectively engaged into said aligned grooves.
Claim 5
Dependent Claim
21 words
