1. A door hinge for a repository of the type having a repository housing with an opening in one face thereof and an edge portion defining the opening, a door member to open and close the opening of the repository housing, and a sealing member sandwiched between the edge portion and the door member to seal the door member and the repository housing when the opening of the repository housing is closed by the door member, the door hinge comprising:

  • a door-support member adapted to be mounted adjacent the edge portion of the repository housing and having a first coupling portion;

    a door-mounted member adapted to be attached to that portion of the door member adjacent to the door-support member in position and having a second coupling portion for cooperatively connecting with the first coupling portion;

    a shaft attached to one of said coupling portions;

    means defining a shaft-fitting slot formed at the other coupling portion, the shaft being fitted in the shaft-fitting slot so that the shaft and the shaft-fitting slot can rock relative to one another and move relative to one another in a direction perpendicular to the face of the repository housing where the opening is formed;

    a guide pin attached to one of said coupling portions; and

    means defining a guide recess formed at the other of said coupling portions for engaging the guide pin;

    the guide pin and the guide recess constraining movement of the shaft and the shaft-fitting slot relative to one another in a direction perpendicular to the face of the repository housing when the door member is moved between a closed and a nearly closed position, and permitting the shaft and the shaft-fitting slot to rock relative to one another when swinging said door member between a nearly closed position and a fully open position wherein said rocking causes said door mounting member to rock relative to said door-support member thereby swinging said door to a fully open position.
