ABSTRACT:
An apparatus for opening and closing a lid disposed rotatably on an opening of a box body selectively in two directions includes a pair of operating members independently movably supported one each at opposite ends of the lid, a spring member having a pair of rotary shafts disposed on an inner side of the lid so as to advance or retreat under the influence of resilient pressure of the spring member, two pairs of storage mouths formed in the edge of the opening of the box body at four corner portions thereof, two pairs of lock members pivotally supported inside the storage mouths for detachably supporting the rotary shafts above the storage mouths, and two pairs of rotary gear mechanisms attached to the lock members so that each pair of rotary gear mechanisms are interconnected to each other and the two pairs of rotary gear mechanisms are interlocked with each other. The rotary shafts are connected to the operating members so as to urge the operating members outwardly away from each other by virtue of the resilient pressure of the spring member. Each of the rotary shafts connected to the operating members is released from the lock members by a pressing operation of the corresponding operating member. The pressing operation of one of the operating members to open the lid in one direction causes one pair of lock members on the side being opened to be rotated and plunged into the corresponding pair of storage mouths due to the interlocking between the two pairs of rotary gear mechanisms.
