Object with forward and subsequent lateral displacement of forward movable surfaces

A door assembly for forward and subsequent lateral displacement of a plurality of forward movable doors, the door assembly comprising:

• a plurality of forward movable doors;
• and
• at least one load-bearing frame comprising:
• a compact linear assembly comprising:
• a principal structural section;
• at least two mutually forward movable bearing sections fastened to the forward movable doors;
• at least two action elements seated in the principal structural section and movable between forward and back positions;
• a mobile assembly in each of the bearing sections for transporting the doors along a guide surface of the action elements and a guideway of the bearing section;
• two stops provided in the principal structural section for limiting the movement of the action element;
• and
• wherein the mobile assembly includes at least one travel wheel mounted between two side plates fixed by means of two flat springs in the bearing section.

A free-standing case comprising:

• at least one wall of the free-standing case comprising at least two mutually overlapping forward movable surfaces capable of lateral displacement;
• and
• at least one load bearing frame which connects individual walls of the case wherein a plane of the load bearing frame is perpendicular to the walls of the case, a linear part of at least one of the load bearing frames is a linear compact assembly, which is parallel with a plane of the mutually forward movable surfaces;
• the linear compact assembly comprising:
• a principal structural section situated parallel to the plane of the forward movable surfaces, the principal structural section providing a second contact surface for fixing of the forward movable surface in a closed position;
• at least two identical action elements each having a constant cross-section along their whole length, freely seated by one of rocking and shifting motion consecutively inside of the principal structural section in a seat, running in the principal structural section, while the principal structural section is in contact with all action elements, and the travel of the action elements is limited by two stops in the principal structural section;
• and
• at least two identical mutually forward movable bearing sections, having a constant cross-section along their whole length and firmly connected with the forward movable surfaces, each bearing section including a mobile assembly situated for free motion of the bearing section on a guide surface of each action element, running along the whole length of the action element parallel with the plane of said forward movable surfaces, wherein each bearing section is provided with a guideway running along its whole length enabling the motion of the adjacent forward movable surface in a forwarded displaced position by means of the mobile assembly on the guideway of the bearing section of the other movable surface in a closed position, whereby the guide surface of the said adjacent movable surface is aligned with the guideway of the bearing section of the said other movable surface in the closed position.
