A latch mechanism for a siderail assembly comprises a handle, a link assembly, and a shaft, The handle is configured to be moved between a first position and a second position. The link assembly is coupled to the handle and configured to move between a latch position and an unlatch position as a function of the movement of the handle. The shaft is configured to be engaged by the link assembly and is configured to rotate from a first rotational orientation to a second rotational orientation to disengage the link assembly from the shaft when a false latching condition occurs.
