Abstract
Articles of furniture are formed employing at least three members joined together by mortises and tenons of which one is a first member, when an additional member or members are needed, one such is the mirror image of the first member. In all disclosed embodiments, each first member or members has a first mortise which extends from one end margin at least part way towards the opposite end portion and a second mortise extending from the fist side margin towards the opposite side margin, intersecting the first mortise and extending beyond it. Another member has a tenon, for each first member extending part way along each side margin and is dimensioned to enable it to be entered in a first mortise and slid in one direction towards the opposite end portion of the first member into a position in which the second mortise thereof is unblocked and in the opposite direction into a position blocking the second mortise. An additional member has a tenon for each second mortise and can be slid therein with the another member in its first position and held therein when that member is in its second position, a mortise and tenon that connects said another and additional members. At least one of the mortise and tenon connections is a self-locking connection.
