Abstract

L'invention a pour objet un piano numérique pliant (1) comportant un caisson (34), et comportant une zone dite « avant » dans laquelle est située un clavier (5), et une zone dite « arrière » (6) opposée à la zone avant, ledit piano comprenant deux parties d'extrémité mobiles (2,3) et une partie centrale fixe (4), les parties mobiles externes (2,3) étant montées à pivotement avec la partie centrale fixe (4), autour d'un axe respectif (7,8), les parties d'extrémité mobiles (2,3) étant aptes à être repliées sur la partie centrale fixe (4). Au moins deux charnières (9,10) sont montées sur chaque axe (7,8) de pivotement des parties d'extrémité mobiles (2,3) sur la partie centrale fixe (4), lesdites charnières (9,10) étant positionnées dans la zone arrière (6), et lesdites charnières situées sur un même axe sont espacées les unes des autres d'une distance telle que le pivotement de la partie mobile (2,3) considérée par rapport à la partie fixe (4) se fait sans déviation par rapport à l'axe (7,8), et lesdites charnières (9,10) sont aptes à permettre une rotation de 180° de chaque partie mobile d'extrémité (2,3) par rapport à la partie fixe centrale (4), et ne sont pas visibles lorsque le piano est déplié.The subject of the invention is a folding digital piano (1) comprising a box (34), and comprising a so-called "front" zone in which a keyboard (5) is located, and a "rear" zone (6) opposite to the front zone, said piano comprising two movable end parts (2, 3) and a fixed central part (4), the external movable parts (2, 3) being pivotally mounted with the fixed central part (4), around a respective axis (7,8), the movable end portions (2,3) being adapted to be folded over the fixed central portion (4). At least two hinges (9,10) are mounted on each axis (7,8) of pivoting movable end portions (2,3) on the fixed central portion (4), said hinges (9,10) being positioned in the rear zone (6), and said hinges located on the same axis are spaced from each other by a distance such that the pivoting of the movable part (2,3) in relation to the fixed part (4) is does without deviation with respect to the axis (7,8), and said hinges (9,10) are able to allow a rotation of 180 ° of each movable end portion (2,3) relative to the fixed part (4), and are not visible when the piano is unfolded.
