ABSTRACT:
A handhole for use on an incubator is disclosed and which comprises only two main components, an injection molded frame attachable to the incubator by hand tightened screws and an injection molded door that is hingedly attached to the frame to pivot between open and closed positions. A bump or projection is formed on the side of the door or flange between the door and frame such that when the door is in its closed position, the bump is caught between the frame and door to cause bending of the door. By location and size of the bump, the amount of bending can be determined such that, when unlatched, the door will spring open a predetermined amount. Thus, the door's flexibility causes initial opening thereof without the need for springs or other accessories. As an added feature, the injected molded frame may include a flange for attaching a conventional wristlet thereto.
