Abstract:
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.
