发明名称 File box with front door
摘要 A file box having a door which is swingably mounted between side walls and biased toward a closed position by a spring engaged around a stub axle. The door has a pair of stub axles, one of which is preferably received in the coil of the biasing spring, which is in turn seated in a socket in one side wall of the box; the other stub axle is received in a slot in the opposite side wall, and is journaled for rotation by the end of the slot. Optionally, the door extends up just a lower portion of the front opening of the box, so as to permit viewing of contents of the box above the door while retaining such contents in the box.
