  • Reset mechanism for stored energy emergency barriers
    Patent number: 8887791
    Abstract: A stored energy emergency barrier release device comprising a barrier and a barrel member for storing the barrier thereon. The barrel member is rotatable on a stationary counterbalance shaft and a push down shaft. The release device further includes a push down spring coupled to the push down shaft for storing potential energy in order to exert a closing force on the barrier when the release device is positioned from an engaged position to a released position. The release device includes a reset mechanism interfaced with the push down spring for transmitting a lifting torque to the push down spring in response to moving the barrier from a first position to a second position to store energy within the push down spring.
