摘要

A door system (100) is provided. The door system (100) comprises a rail mount (101) and a carriage (102) mounted on the rail mount (101). The carriage is movable along a longitudinal axis of the rail mount (101). The carriage (102) is adapted to couple to a door. The door system (100) can further include a fluid actuator (103) with a cylinder (106) coupled to the rail mount (101) and including a piston rod (206) extending from the cylinder (106) and coupled to the carriage (102). The door system (100) can also include a return assembly (104) coupled to the carriage (102) and providing a biasing force on the carriage (102) and the piston rod (206) in a first direction. The door system (100) can further comprise a braking assembly (105) coupled to the rail mount (101) and when actuated substantially prevents the piston rod (206) and the carriage (102) from moving in the first direction for a predetermined amount of time while the return assembly (104) simultaneously provides the biasing force on the piston rod (206) and the carriage (102).
