Abstract
Abstract The invention relates to corner work table (1), in particular for office work, comprising a subframe (2) and a corner table top (3). The table top has the form of a circular segment, the radius sides being formed as connection sides (5,6) to further adjoinable table tops (17,18). The securing is effected by edge-side angle rails (34) and by openings in a support tube (11), into which the support arms (33,41) are insertable. The subframe (2) comprises a floor-side stirrup member (8) to which four support legs (9,10,14,15) are attached on which support tubes (11,16) are secured which in turn carry the corner table top (3). This subframe structure provides a high stability and firmness of the corner work table (1) and due to the form of the member (8) open towards the wide side of the corner work table a large degree of foot freedom for the user. For lowering a table top (17) compared with the height of the corner table top (3) a support plate is further proposed with support arms (40) secured thereto, said arms (40) engaging below and supporting the table top (17). It is achieved with the corner work table (1) shown that with adjoining table tops (17,18) the latter are supported at the joints by the subframe (2) of the corner table (1).
