Publication number: 20120241105Abstract: An overhead roll-up door assembly for a vertically moving door to permit and prohibit access to an opening in a wall, the door assembly having a flexible door panel and side columns located proximate opposite sides of the opening. The side columns each include an arm configured to engage the door panel as the door panel moves vertically, the arms being configured to move in a first direction in response to a first threshold moment being applied to the arms by the door panel wherein movement of each arm in the first direction prevents the door panel from escaping the side columns. The arms may be further configured to move in a second direction in response to a second threshold moment being applied on the arms by the door panel in a substantially vertical direction perpendicular to and away from the door panel.Type: ApplicationFiled: November 30, 2011Publication date: September 27, 2012Applicant: RYTEC CORPORATIONInventors: Brian Norbert Drifka, Christopher Gontarski

Patent number: 6910301Abstract: A door seal for use with a bi-parting door in which the door panels of the door have supplementary angled leading edges. One leading edge has a triangular cross-section, while the other has a cross-section similar to a parallelogram. To further the reliability of the door seal, a plurality of magnets with corresponding magnet attracting plates may be attached along the leading edges. Alternatively, both leading edges may have at least one magnet aligned with a magnet on the other edge. With the double magnet configuration, the use of multi-pole magnets is necessary. The magnets also help reduce the bounce between the door panels, which may be closed roughly, and increase the force required to separate the door panels when closed.Type: GrantFiled: January 3, 2002Date of Patent: June 28, 2005Assignee: Rytec CorporationInventors: Walenty Kalempa, Brian Norbert Drifka

Publication number: 20040206004Abstract: A door for at least partially covering a doorway defined by a wall and a lower surface. The door comprises a first door panel adapted to laterally translate along a plane relative to the doorway between a doorway blocking position and an unblocking position. The door further comprises a first seal including a first sealing surface interposed between a first attachment end and a first distal end with the first attachment end being attached to the first door panel. The door also has a second seal disposed to allow relative movement between the first seal and the second seal, the second seal including a second sealing surface interposed between a second attachment end and a second distal end, such that the first door panel in the doorway blocking position causes the first sealing surface to face the second sealing surface and positions the second distal end between the first distal end and at least one of the first door panel and the first attachment end.Type: ApplicationFiled: May 3, 2004Publication date: October 21, 2004Inventors: Walenty Kalempa, Brian Norbert Drifka
