A storage unit (10) includes a counterbalanced door arrangement (22). The counterbalanced door arrangement has an upper door (30) between pivoting arms (28), in combination with a lower door 34 between pivoting arms (32). A link (27) is interconnected between the upper and lower arms, for providing synchronous movement of the upper and lower doors between open and closed positions. A counterbalancing member (52,84) urges the upper and lower doors open. The counterbalancing member may be a spring (52) which provides an assist when moving the upper and lower doors toward their open positions, and which functions to retain the upper and lower doors open. When the upper and lower doors are closed, the weight of the upper door (30) and a forward portion of the upper arms (28) is operable to overcome the biasing force of the spring (52), to maintain the upper and lower doors closed.

L'invention concerne un meuble de rangement (10) doté d'un dispositif de portes à contrepoids (22), lequel est constitué d'une porte supérieure (30), disposée entre des bras pivotants (28) et combinée à une porte inférieure (34) située également entre des bras pivotants (32). Une liaison (27) relie les bras supérieurs et inférieurs pour synchroniser le mouvement des portes supérieure et inférieure entre les positions ouverte et fermée. Un élément d'équilibrage (52,84) provoque l'ouverture des portes supérieure et inférieure. En effet, cet élément d'équilibrage, qui peut être un ressort (52), aide les portes supérieure et inférieure dans leur mouvement d'ouverture, puis il les maintient ouvertes. Lorsque les portes sont fermées, le poids de la porte supérieure (30) et une partie avant des bras supérieurs (28) servent à surmonter la force de sollicitation du ressort (52), afin de maintenir les portes supérieure et inférieure fermées.
