Abstract
The panic exit device includes several features which improve its ease of use and operability over earlier devices including: (1) an improved latch deadlocking mechanism; (2) an improved latch to pad mechanism; (3) a pad lock down feature; (4) an improved universal mounting plate and easily mounted strike; and (5) a vertical rod-bottom bolt deadlockig mechanism in its center case. The latch deadlocking mechanism includes a deadlock link, which in the event of a fire, will block the movement of the latch bolt.
Claims6
A panic exit device, comprising:
- a modular latch assembly, said modular latch assembly comprises a latch bolt, an auxiliary bolt, a deadlock link, and a retractable main link carriage, said latch bolt, said auxiliary bolt, said deadlock link, and said retractable main link carriage are coupled together and are biased in a first, latched position and movable to a second, unlatched position by retraction of said main link carriage, said auxiliary bolt moves independently of said main link carriage to actuate said deadlock link;
- and
- a modular push bar/action bar assembly, said modular push bar/action bar assembly comprises an action bar, a push bar, and a first hook element, said push bar couples to said action bar by a rocking mechanism, said rocking mechanism translates a forward motion of said push bar into a lateral motion of said action bar, said first hook element is coupled said action bar and further couples to said modular latch assembly and transfers lateral motion of said action bar to said main link carriage.
