| 摘要 |
The invention consists of a folding structure (2) having one or more rollers (3) coupled thereto and comprising a single articulated part formed by a plurality of straight segments (2a, 2b) that are interconnected by articulated connections with a shaft (4) for vertical rotation and movement of the segments in the horizontal plate, and hinged connections with a shaft (5) for horizontal rotation and movement of the segments in the vertical plane. In the use position, the table takes the form of a rectangular frame, while in the folded position it forms a compact, flat, elongate block. The upper part of the structure (2) includes recesses (8) provided with projecting lugs (9) that can be inserted into holes (10) in the ends (3a) of the shaft of the rollers (3), while the lower part includes supporting blocks (11) made from non-slip material. Each of the connections between the transverse (2a) and longitudinal (2b) segments includes an articulation (4) allowing vertical rotation through up to 270° and another hinged articulation (5) allowing horizontal rotation between the longitudinal segments (2b) through up to 180°. The table can be folded along the middle at its smaller central shaft. |
