## Abstract

Two lateral parts (1) interconnected by an upper support (21) are provided in an office furniture unit, with an adjustable table top (22) being arranged between said lateral parts. The adjustment of the table top in the tilt and vertically is accomplished by lateral and posterior pin engagements (35 and/or 32). A bolt (28) which is positioned for reciprocal movement is arranged in the posterior edge (26) of the table top (22). The head (54) of the bolt (28) grips behind a vertical slot (38) of the support (21). Upon disengagement of the table top for its adjustment, it remains connected to the support via the bolt so that it cannot drop out.
