Upper structure for e.g. writing desk utilized in school, has tray plate rotatable around tilting axis, such that tray plate is bent from rear edge to front edge when structure is not arranged in basic position

摘要

The structure (7) has a worktop (10) extending from a leading edge (11) to a trailing edge in longitudinal direction. The structure is adjusted between a basic position and a limiting position, where a top surface of the worktop cooperates with a top surface of a tray plate (17) in the basic position to form a planar coherent working surface. The tray plate is rotatable around a tilting axis (12), such that the tray plate is bent from a rear edge to a front edge when the structure is not arranged in the basic position.
