<p>The object with forward and subsequent lateral displacement of forward movable surfaces, particularly a display case, cabinet, door, consists of mutually forward movable surfaces (6) and at least one load-bearing frame (1) comprising a linear compact assembly (2) consisting of the principal structural section (3) and at least two mutually forward movable bearing sections (5) firmly connected with the mutually forward movable surfaces (6) and action elements (4). In every bearing section (5) there is a mobile element (51) mounted movably on a guide gib (41) of the action element (4) mounted in the principal structural section (3). The movement of the action element (4) is limited by two stops (32 and 33) provided in the principal structural section (3). The mobile element (51) of the bearing section (5) rolls to advance along the guide gib (41) of the action element (4) which may consist in a lever rocking in a seat (38) provided in the principal structural section (3) or a sliding rider travelling between two stops (32 and 33). The mobile element (51) consists to advantage of at least one travel wheel (511) installed between two side plates (512) fastened in the bearing section (5) by means of two flat springs (513). The free part of the forward movable surface (6), in the 'closed' position, is mounted between juxtaposed surfaces (81 and 82) of the principal closing section (8) forming part of the object (0) of which also the forward movable surfaces (6) form part. In the principal structural section (3) there is a compression spring (37). The principal structural section (3) may be provided with grooves for the installation of the mechanisms for the suspension of shelves, lighting and the connection of supplementary display case elements.</p> |
