Upper seal for a horizontal side-moving door

A door for a wall defining a doorway with an upper edge and a lateral edge, wherein the door is horizontally movable between an open position and a closed position such that the door obstructs the doorway when the door is in the closed position, and the door exposes the doorway when the door is in the open position, the door comprising:

• a track mountable in proximity with the upper edge of the doorway;
• a track follower mounted to the track for translation therealong;
• an elongate member extending downward from the track follower to travel therewith to define a path of travel;
• a curtain that includes a leading edge and an upper edge, the leading edge is connected to the elongate member and is generally parallel thereto, the upper edge is generally perpendicular to the leading edge, the curtain is more flexible than the elongate member, the curtain to at least partially obstruct the doorway when the door is in the closed position;
• a seal guide defining a seal groove and positioned in laterally-spaced relation to the path of travel of the elongate member so that the upper edge of the curtain protrudes into the seal groove and slides along the seal groove as the door opens and closes, a groove into which a portion of the seal guide extends at least partially defined between the upper edge and the elongate member;
• and
• two contacting seal member portions at least partially defining the seal groove, wherein the two contacting seal member portions are able to contact a rear surface and a front surface of the upper edge of the curtain.

A door for a wall defining a doorway with an upper edge and a lateral edge, wherein the door is horizontally movable between an open position and a closed position such that the door obstructs the doorway when the door is in the closed position, and the door exposes the doorway when the door is in the open position, the door comprising:

• a track mountable in proximity with the upper edge of the doorway;
• a track follower mounted to the track for translation therealong;
• an elongate member extending downward from the track follower, the elongate member comprising a first portion having a first thickness and a second portion having a second thickness, the second thickness being thicker than the first thickness, the first portion to be positioned between the track follower and the second portion;
• a curtain comprising a leading edge and an upper edge, the leading edge being coupled to the elongate member, the upper edge being substantially perpendicular to the leading edge;
• and
• a seal guide defining a seal groove positioned to enable the upper edge of the curtain to protrude into the seal groove and slide along the seal groove as the door opens and closes, a portion of the seal guide being positioned in a groove at least partially defined by the upper edge of the curtain and the first portion of the elongate member to enable a surface of the curtain to seal with the seal guide and enable the elongate member to be moveable between the open and closed positions.
