1. A door system disposed within a portal aperture of a transit vehicle having a side wall member with outer and inner surfaces,
a ceiling portion adjacent said side wall member and said aperture, and a floor portion disposed adjacent said portal aperture
and said side wall member, said floor portion having a level outer edge extending across said portal aperture, said floor
portion extending from said outer edge at an angle with respect to a horizontal plane, said door system comprising:
(a) a door drive disposed adjacent said portal aperture, said door drive having a base attached to one of said ceiling portion
and said inner surface of said side wall member, a prime mover selected from the group consisting of electrical, mechanical,
pneumatic, and hydraulic prime movers, and at least one drive linkage connected to said prime mover at one end of said drive
linkage;
(b) at least one door rotation enabling device disposed vertically within said transit vehicle adjacent said inner surface
of said side wall member, said at least one door rotation enabling device having a first pivot connection with said at least
one drive linkage, an upper arm, and a lower arm;
(c) at least one door for at least partially covering and uncovering said portal aperture, said at least one door including
a door body member with a leading edge and a bottom edge, an upper portion for coupling with said upper arm, a lower portion
for coupling with said lower arm, said at least one door movable between a first position disposed generally co-planar with
said side wall member and a second position disposed perpendicularly to said side wall member upon rotation of said at least
one door rotation enabling device, said at least one door being disposed above said floor portion in said second position;
and
(d) a sealing arrangement at least partially attached to said at least one door, said sealing arrangement sealingly engaged
with and generally parallel to said level outer edge of said floor portion when said at least one door is in said first position
and said sealing arrangement is generally parallel to said floor portion when said at least one door is in said second position,
said sealing arrangement including:
(i) a mounting member having a body portion with at least one cavity;
(ii) at least one sealing member attached to said mounting member with at least one fastener engaging said at least one cavity;
and
(iii) a motion conversion mechanism at least partially attached to said mounting member which moves said at least one sealing
member in a first vertical direction during rotation of said at least one door from said first position to said second position
and which moves said at least one sealing member in a second vertical direction during rotation of said at least one door
from said second position to said first position, said second vertical direction being substantially opposite said first vertical
direction.
