Abstract
A seal system for a bi-fold door having a first panel and second panel includes a first seal attachable to the first panel and a second seal attachable to the second panel. Each seal includes a mounting portion, a bulb portion, and a flap portion. When the bi-fold door is closed, the flap portion of the first seal overlies the second seal, and the flap portion of the second seal overlies the first seal.

A system comprising:
- a first panel having a first panel thickness, a first panel leading edge and a first panel trailing edge, the first panel pivotally mounted on a first pivot axis proximate the first panel leading edge;
- a second panel having a second panel thickness, a second panel leading edge and a second panel trailing edge, the second panel pivotally mounted on a second pivot axis proximate the second panel trailing edge, the second pivot axis parallel to and spaced from the first pivot axis;
- the first panel and the second panel pivotally operable between first positions in which the first panel is generally co-planar with the second panel and the first panel trailing edge is generally adjacent to the second panel leading edge, and second positions in which the first panel is not substantially coplanar with the second panel;
- a first seal attached to the trailing edge of the first panel, the first seal comprising:
- a first seal mounting portion;
- a first seal bulb portion;
- and
- a first seal flap portion;
- wherein the first seal flap portion extends from the first seal bulb portion;
- a second seal attached to the leading edge of the second panel, the second seal comprising:
- a second seal mounting portion;
- a second seal bulb portion;
- and
- a second seal flap portion;
- wherein the second seal flap portion extends from the second seal bulb portion;
- wherein the first seal bulb portion abuts the second seal bulb portion, the first seal flap portion overlies the second seal, and the second seal flap portion overlies the first seal when the first panel and the second panel are in the first positions.
