Abstract
A roll-up door assembly includes a header, a face frame, and a lift frame. The lift frame is removably coupled to the header and is configured to be conveniently discarded once the header is securely installed to the face frame. The header further includes links along at least one end of individual slats that comprise a door panel. The links and the slats are configured to be rolled and unrolled from a spiral as the door panel is opened and closed. The links include a noise abatement feature that is adapted to decrease a sound pressure level associated with the links impacting, for instance, one another during the process opening and closing the door. The links further include a friction reduction surface that reduces friction at the coupling of adjacent links.
Claims20
A roll-up door assembly comprising:
- a plurality of links operatively coupled and configured to coil and uncoil during use, at least some of the plurality of links include at least one of a rib and a groove, wherein the ribs and the grooves are configured such that the rib can nest within the groove when the plurality of links are coiled;
- a secondary channel in at least one of the groove and the rib of a first link of the at least some of the plurality of links;
- and
- an insert seated within the secondary channel and configured to extend beyond the secondary channel to interface with the groove or the rib of a second link of the at least some of the plurality of links coiled to stack with the first link.
A link capable of use with a roll-up door, the link comprising:
- a rib;
- a groove opposite to the rib;
- a secondary channel in one of the rib and the groove;
- and
- an insert seated in and extending from the secondary channel.
A roll-up door assembly, comprising:
- a plurality of links coupled end-to-end and configured to spiral during use;
- a first link of the plurality of links defines a rib;
- a second link of the plurality of links defines a groove sized to receive the rib;
- a secondary channel formed in at least one of the rib and the groove;
- and
- an insert seated in the secondary channel and extending at least partially out of the secondary channel.
