Abstract:
In a door latching assembly having a first latch having a first latch element rotatable between latching and unlatching positions and yieldably urged toward the unlatching position, and a first trip lever rotatable between latched and unlatching positions and operable during such rotation to release the first latch element to rotate to the unlatching position, the improvement which comprises:a second, similar latch spaced from said first latch and having a second latch element rotatable between latching and unlatching positions, and a second trip lever rotatable between latched and unlatching positions and operable during such rotation to release the second latch element to rotate to the unlatching position;a slide disposed alongside said first latch;means mounting said slide on said first latch for relative movement thereon toward and away from said second latch between first and second limited positions;an elongated link connected adjacent one end of the link to said slide and adjacent the other end of the link to said second trip lever for movement of the second trip lever in response to movement of the slide relative to said first latch;spring means acting between said first latch and said slide to urge the latter yieldably toward said second latch and into the first limited position;means permitting selective adjustment of the effective length of said link thereby to set the timing of movement of the second latch element to the unlatching position;and a connection between said first trip lever and said slide for transmitting rotary motion of the first trip lever from the latched position toward the unlatching position to the slide and through the link to the second trip lever, thereby to move the second trip lever to the unlatching position during such motion.
