The movable drawer (3) has roller slides (22, 22a) including rubber wheels (23, 23a) rolling and un-rolling on U-shaped channels (24, 24a) of vertical guiding rails (25, 25a), where the drawer is downwardly driven by an electrical circuit breaker (40) over a tube motor (31) when pulling the drawer from a compartment (4) of a tall cupboard (1) to a stopper. Cable straps (30, 30a) are wound up on the tube motor till activating a limit switch at an uppermost position so that the drawer is inserted into the compartment of the tall cupboard. |
