| 摘要 | A lock mechanism enabling locking of a bi-parting set of right hand and left hand door panels respectively suspended from a right hand and left hand door operators, to be driven by the door operators for covering and uncovering an aperture disposed within a passenger transit vehicle. Such lock mechanism disposed intermediate the door operators. The lock mechanism is capable of operating in a pushback and non pushback arrangement providing a fully-locked state, for each of the two bi-parting doors of a passenger transit vehicle. The integrated design allows the central lock mechanism to be installed and/or maintained over a doorway with only minimal adjustments needed to assure that the door lock assemblies operate in unison. As compared to separate door lock assemblies for each door panel as is typical of prior art designs, the central lock mechanism enables the door panels to be closed and locked more reliably and with better sealing against weather and noise. | ||||||
