ABSTRACT:
A sealing arrangement is provided that includes a resilient seal member that is disposed generally parallel to the pivot axis of an access door of an enclosure. The seal member includes a first leg proximate the hinge axis and extending away from the enclosure. When the door is pivoted from an open position toward the closed position, the first leg is displaced toward the enclosure. As the door is further moved toward the closed position, the first leg is additionally displaced, deformed and compressed to provide sealing of the door with respect to the enclosure. The proximity of the seal member to the hinge axis and the arrangement of the first extending leg is such that relative wiping action occurs between the door and the first extending leg. In a preferred arrangement, the seal member also includes a second leg extending from the enclosure. The second leg is termed an inner leg since it is adjacent or proximal the access opening and the first leg is termed an outer leg since it is distal of the access opening and proximate the hinge axis. Wiping action also occurs between the second leg and the door as the door is closed. During door closure, the second leg is displaced and deformed toward the enclosure. With the door in the fully closed position, the second leg is also deformed and compressed to provide a seal against the door.
