SIMULTANEOUSLY MOVABLE AND TILTABLE WORKTOP FOR STUDY DESKS AND WRITING TABLES

摘要

The invention relates to articles of educational furniture and can be used for organized learning. The essence of the invention is that in a tiltable worktop connected to a supporting framework by a hinged joint, the hinged joint between the worktop and the supporting framework is formed via two rotatable surfaces of different widths. The aim of the invention is to provide a worktop for writing tables and study desks which can be tilted and moved by means of a single action. The structure of the worktop is illustrated in the drawings. Figure 1 shows a side view with no tilt of the worktop; figure 2 shows a side view with the worktop tilted; and figure 3 shows a front view with the worktop tilted. The structure comprises: a worktop (1) (figures 1, 2, 3); a hinged joint (2); a supporting framework (3); a rotatable surface (4); a rotatable surface (5); a limit stop (6); and a rotatable handle (7). When the handle (8) (figure 1) is rotated, the worktop (1), which is connected to the supporting framework (3) via the rotatable surfaces (4, 5), moves with the aid of the hinged joints (2) towards the seated person and comes to rest on the limit stops (6, 7) (figures 2, 3). Since the rotatable surfaces (4, 5) are of different widths, the angle of incline of the worktop to the horizontal changes during rotation. The technical result of the proposed study desk worktop is that, by a single movement of the handle, the worktop is transferred from a horizontal position into a tilted position while the edge of the worktop is brought closer to the student.
