摘要： A vertically operating door and its drive system can be configured to push a door panel along a track to various overhead storage configurations including vertical, horizontal, inclined and coiled. Semi-flexible drive strips extend continuously along lateral edges of the curtain. The system includes a drive gear that engages a series of projections on at least one drive strip so that the gear can push the door between its open and closed positions. To protect the door from being damaged by collisions, the track can include a breakaway feature that allows at least a portion of the panel with its drive strip to separate from the track without permanent distortion. The drive strip and panel remain together as they break away from the track. The threshold of the breakaway force can be changed by selecting a retention strip from a plurality of interchangeable strips having different degrees of flexibility.

摘要： An example of an inflatable seal for a door includes a bi-directional airflow pattern of frost-inhibiting heated air. The bi-directional flow pattern enables the seal's discharge opening and supply air blower to both be located well above the floor and preferably above the doorway. If the discharge opening is near the suction inlet of the blower, such an arrangement makes it possible to recover previously heated air by returning some of the warm air back to the blower. In some examples, the seal includes a supply air conduit and a return air conduit with one disposed within the other. The internal conduit may include a relatively stiff elbow to prevent that conduit from becoming kinked near an upper corner of the door.
摘要翻译： 用于门的可充气密封件的示例包括防冻热空气的双向气流图案。 双向流动模式使得密封件的排放开口和供气鼓风机都位于地板之上，优选位于门口上方。 如果排出口靠近鼓风机的吸入口，则这种布置使得可以将一些暖空气返回到鼓风机中来恢复先前加热的空气。 在一些示例中，密封件包括供给空气管道和具有设置在另一个内部的返回空气管道。 内部导管可以包括相对较硬的弯头，以防止导管在门的上角附近变得扭结。
