Dual Watertight Method for Sealing a Hinged Door

      Disclosed is the use of front and rear compression seals to
form a watertight seal around a hinged door which, when closed, is
flush with the surface of the surrounding system frame.

      The Figure is a transverse cross-sectional view of the door in
its closed position.  The door 1, which is hinged to open outward in
the direction of arrow 2, includes a front frame 3, a rear frame 4, a
sealed keypad 5, and a front gasket seal 6.  Front gasket seal 6
includes a rear rounded bead 7, which is clamped between front frame
3 and rear frame 4 to mount the seal within the door 1.  A rear
gasket seal 8 stays in a channel 9 of the system frame 10 as the door
1 is opened.  As door 1 is closed, a rib 11, extending rearward as a
part of rear frame 4, compresses rear gasket seal 8, and an outer
sealing surface 12 of system frame 10 compresses front rounded bead
13 of front gasket seal 6.  These elements extend along all four
sides of the rectangular door 1.

      The rear gasket seal 8, which is composed of an elastomeric
material having a relatively low durometer, is compressed through a
large percentage of its thickness by rib 11, forming a watertight
seal.  The front gasket seal 6, which is composed of an elastomeric
material having a much higher durometer forms a seal preventing
foreign materials from moving into the gap along the edge of door 1
between front gasket seal 6 and rear gasket seal 8.  Since the...
