Abstract

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.

First claim

What is claimed is:

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 su…
