Patent ID: 8863815

Claim:
A door system, comprising: a track defining a channel; a door, comprising: a panel to be movable between an open position and a closed position, wherein the panel includes a lateral edge adjacent the track when the panel is in the closed position; a first material coupled to the lateral edge of the panel and extending from within the channel to outside the channel toward a center of the panel when the panel is in the closed position, wherein the first material is non-separably coupled to the lateral edge of the panel, the first material unitarily formed to extend substantially a length of the lateral edge of the panel; a plurality of projections disposed along the first material such that the plurality of projections are positioned within the channel when the panel is in the closed position, wherein one or more of the plurality of projections engages a portion of the channel when the panel is in the closed position to retain the plurality of projections within the channel, at least a portion of the first material and one or more of the projections exiting the channel when a force greater than a threshold force acts upon the door; and a second material attached to the panel, the second material extending in a lengthwise direction generally parallel to the track when the panel is in the closed position, the second material unitarily formed to extend substantially the length of the lateral edge of the panel; and a drive mechanism to engage one or more of the projections without extending through the door to move the panel between the closed position and the open position, wherein the second material is to transmit a majority of a transmission force to move the panel between the closed position and the open position.
