Convertible suitcase

A combination suitcase and chest-of-drawers, comprising a plurality of stackable and hand-portable suitcase units, each suitcase unit comprising

• an outer envelope member,
• an inner drawer member slidably mounted in said envelope member, and
• said envelope member having two generally planar parallel sides thereto, the outer surfaces of said sides having interlockable bead portions thereon formed to upstand therefrom and dimensioned so as to engage the corresponding interlockable portions on the confronting face of a second suitcase unit brought into juxtaposition therewith and to impede relative movement of the two suitcase units with respect to each other in the plane of said planar parallel sides,
• each of said envelope members further comprising a retaining latch mechanism borne on the rearward side of said envelope member, said latch mechanism comprising a channel member fixed to said envelope member and formed with a channel therein oriented generally perpendicular to said planar parallel sides and generally parallel to said rearward side, and a bolt member slidably mounted in said channel member and selectively partially engageable with a corresponding channel member on an envelope member placed adjacent thereto while retaining partial engagement with said first-named channel member, to restrain relative movement between said envelope members.
