Bi-parting, bi-directional door system

摘要

A door system includes two bi-parting, center-opening, bi-directional door panels disposed for counter-rotating swinging movement in a doorway. An operator is coupled to the door panels via a synchronizing system such that the door panels may be selectively opened in either direction relative to the doorway, and closed in the opposite direction, and such that the door panels swing through substantially equal angular distances. The synchronizing system may include a linkage, among other systems, and the operator may include an electro-mechanical operator, a mechanical door closer with spring, or a hybrid of both. A person may effect an emergency breakout by manually using a single-motion, low-force push against one of the door panels to simultaneously open both door panels.

1. A door system, comprising:
two bi-parting, center-opening, bi-directional door panels disposed for counter-rotating swinging movement in a doorway; a synchronizing system operatively associated with the door panels; the synchronizing system being operative to swing the door panels simultaneously selectively outwardly or inwardly of the doorway to open the door panels, and to simultaneously close the door panels, such that the door panels swing through substantially equal angular distances during opening and closing; wherein the synchronizing system including a linkage system, and further including two motion converters, the linkage system and motion converters being operatively associated with the door panels; the linkage system including first and second linkages, each defining a driven link; each motion converter being drivingly connected to a respective door panel and being operative to convert the motion of respective driven links to rotary motion; such that rotation of one door panel through a predetermined angular distance, whether inwardly or outwardly of the doorway, simultaneously rotates the other door panel through substantially the same angular distance; wherein the first and second linkages lying in the same plane; each of the first and second linkages defining a driver link pivotably connected to a connecting link, which in turn is pivotably connected to a respective driven link; such that the driver and driven links of the first linkage remaining in parallel throughout the operation of the synchronizing system, and the connecting link of the second linkage being disposed at an angle to the connecting link of the first linkage, such that the driven link of the second linkage rotates in a direction opposite to the direction of rotation of the driven link of the first linkage.
