1. Market stall, containing a base, a table top and a roof, characterized in that it consists of supporting elements (1) having lengthwise axes lying in different parallel planes, bracing elements of the base (2) and (3), horizontal elements of the base (4) and (5), bracing elements of the table top (6) and (7), bracing elements of the roof (8) and (9), supporting elements of the roof (10) and (11), extending elements (12) and distance elements (13) and (14) connected together detachably at nodes (A), (B), (C), (D), (E), (F), (G), (H), (I), (K), (L), (M), (N), (P), (R), (S), (T) and forming two three-dimensional structural systems connected at nodes (A), (B), (G), (H), (I), (K), (L), (M), (N), (S), (T) by means of tubular bracing elements (15), (16), (17), (18), (22), (29), (30), (31), (32), (34), (35), while the horizontal elements of the base (4) and (5) connect on one side to the supporting elements of the structure (1) to form nodes (A) and (B), and on the other side to the bracing elements of the base (2) and (3) to form nodes (C) and (D), where the bracing elements (2) and (3) connect at nodes (E) and (F) to the bracing elements of the table top (6) and (7), which connect at nodes (G) and (H) to moving distance elements (13) and (14) threaded onto bracing elements (17) and (18), while the table top consists of alternately arranged fixed elements (21) threaded onto three parallel bracings (17), (18), (22) and moving stand elements (23) and (24) whose lengths are equal to half the length of the elements (21), forming pairs in which the elements (23) are threaded onto a bracing (17)...<IMAGE>
