11 Claims
1. A door hold-open device comprising:
a. a track;
b. a slide block catch feature slidably mounted for longitudinal movement in the track;
c. a stop assembly comprising:
i. a stop assembly catch coupled to the track and adapted to engage the slide block catch feature wherein the stop assembly
catch is moveable in a direction different than the longitudinal direction,
ii. a resilient member that applies a force to the stop assembly catch to urge the stop assembly catch into a position where
the stop assembly catch engages the slide block catch feature when the slide block catch feature is adjacent to the stop assembly
catch;
d. a linear actuator having a first position and a second position, wherein the linear actuator applies a first force to the
resilient member in the first position and a second different force to the resilient member in the second position;
wherein said slide block catch feature is free to travel beyond said stop assembly catch along at least a substantial portion
of any remaining length of said track, thus allowing a door to open beyond said stop assembly.
