This showcase for preservation and display of objects comprises a fixed casing (10) and at least one openable panel (20) made of glass mounted on the fixed casing (10) through opening supports (30), which comprise a pair of upper rods (31 a) and a pair of lower rods (31 b), all having the same length as each other, pivoted to the fixed casing (10) at respective first upper (32a) and lower (32b) rod pins, and an intermediate structure (40), pivoted to the upper and lower rods (31) at respective second upper (33a) and lower (33b) rod pins. The rod pins (32, 33) have a pivoting axis parallel to a main direction (X). The distance on the fixed casing (10) between the first upper rod pins (32a) and the distance on the intermediate structure (40) between the second upper rod pins (33a) are equal to each other, as well as the distance on the fixed casing (10) between the first lower rod pins (32b) and the distance on the intermediate structure (40) between the second lower rod pins (33b) are equal to each other, so that the four rods (31) form an articulated parallelogram system for the movement of the intermediate structure (40) with respect to the fixed casing (10). A hinging system (51) is provided along the main direction (X), between the openable panel (20) and the intermediate structure (40), so as to allow the openable panel (20) to rotate with respect to the intermediate structure (40). With this structure, the opening of the openable panel is divided substantially into two steps, with a first roto-translational movement of the intermediate structure and with it of the openable panel with respect to the case, and a second step, in which the hinging system is used to allow the openable panel to rotate with respect to the intermediate structure, until a completely open position is reached. |
