System for adjusting surface level

A system for adjusting surface level, comprising:

• a moveable surface;
• at least two structures adapted to be disposed between and coupled to said moveable surface and a fixed surface, said at least two structures being radially displaceable in the same direction;
• a single force transfer mechanism configured to be coupled to at least one of said at least two structures for displacement of said moveable surface relative to said fixed surface, and wherein said single force transfer mechanism is operative for enabling parallel displacement of said movable surface with respect to said fixed surface, whereas said at least two structures being displaceable in parallel to each other in a first mode of operation,
• and wherein said single force transfer mechanism is further operative for enabling radial displacement of said movable surface with respect to said fixed surface, whereas said at least two structures being relatively displaceable radially with respect to each other in a second mode of operation,
• and wherein said at least two structures comprise a first structure having at least one solid rod being disposed between and adapted to be coupled to said fixed surface and to said moveable surface and a second structure having at least one solid rod being disposed between and adapted to be coupled to said fixed surface and to said moveable surface, wherein said first structure is spaced apart from said second structure,
• and a connecting rod disposed between said first structure and said second structure, wherein said connecting rod is moveably coupled to said first structure at a first end and hingedly coupled to said second structure at a second end.
