draws the inner door 24 into the truss 32 to remove gaps 41 a and 41 b and slightly bend the inner door 24 force f a creates an outward bias force f b at the top 29 of the door assembly 20 these forces cooperate with the door strike 28 and latch 30 of the drying cabinet 14 to maintain the doors in the closed position the truss member 32 is illustrated in use on the right door assembly 20 alternatively the truss member 32 may be on both the left and right door assemblies 20 typically the drying cabinet 14 is designed such that one door assembly 20 closes over the other to form a seal when only one truss member 32 is used the truss 34 is preferably upon the side of the drying cabinet 14 that closes over the other side as illustrated in the figures the right side door of the drying cabinet 14 closes over left side door and therefore the right side door would preferably have the truss member 32 even if the truss member 32 is not used within a door assembly 20 the blocks 50 are still utilized to create curvature of the outer skin panel 22 in operation the user will grip the handle 26 as seen in fig1 and pull outward to open the door assembly 20 the outward force by the user disengages the door strike 28 from the latch 30 permitting separation of a seal at the top of the door assembly 20 the user rotates the door assembly 20.
