Abstract
A table extensible by turning over its side boards, constituted by a horizontal plane, having peripheral parts with upper side boards and lower side boards shaped as circle segments and a central part enclosed thereby. The central part is able to rotate on a base and is vertically movable relative thereto by means of cam profiles, which are fastened to the central part between the top surface of the lower side boards and of the upper side boards, which are fastened to the central part. The lower side boards are joined to a frame, bearing down on said base whilst the upper side boards are hinged to the upper side boards to be turned over outwardly.
Claims10
An extensible table comprising:
- a base;
- and
- a table top;
- the table top comprising:
- a lower side having a plurality of first side boards each having a first straight edge and a first curved edge, each end each of the first side boards being respectively fixed to an end of an adjacent first side board to form a coplanar surface having a first opening enclosed by the curved edges;
- an upper side having a plurality of second side boards each having a second straight edge and a second curved edge, the first and second straight edges and the first and second curved edges being equal to each other, the straight edges of the second side boards being respectively hinged to the straight edges of the first side boards to permit rotation from a first position wherein the second side boards overlay the first side boards to form a second opening equal to that of the first opening to a second position where the second side boards are coplanar with the first side boards;
- and
- a central part having a periphery equal to that of both the first opening and the second opening, a vertical shaft rotatably engaged in a vertical recess on the base and an inclined cam means fixed to a bottom side of the central part to permit rotating the central part in the vertical recess so that the central part is engaged on the base to be either coplanar with the second side boards in the first position or coplanar with the first side boards in the second position.
