An actuatable slidable panel assembly, a retrofit kit for converting a slidable panel of a panel assembly from manually actuated sliding movement to mechanically assisted, actuatable sliding movement, and method of retrofitting a manually operating sliding panel therewith are provided. The retrofit kit includes an elongate driven rail configured for attachment to the slidable panel. The elongate driven rail is configured to be attached to the slidable panel. A rotatable drive member is configured for operable engagement with the elongate driven rail to drive the elongate driven rail and the slidable panel along the direction of travel between open and closed positions.

A door driving device includes: a base member extending in an opening width direction of a door; a rotary moving unit pressed against the base member and configured to move along the base member while rotating; a rotary shaft extending in the opening width direction of the door and configured to rotate by a power of a motor; and a transmission member. The transmission member can move relatively to the rotary shaft in the axial direction thereof. The transmission member also rotates along with the rotary shaft and contacts with the rotary moving unit, thereby to transmit the rotational power of the rotary shaft to the rotary moving unit.

The invention relates to a transmission for a boarding system for a rail vehicle, in which the transmission comprises a linearly movable drive shaft for an element of the boarding system, the drive shaft comprising a straight drive region and a curved locking region adjacent thereto, a drive wheel arranged at a distance from the drive shaft, a step-up gear that can move on a circular path around the drive wheel and is coupled to the drive wheel and the drive shaft, and an abutment device for defining a range of movement of the step-up gear between a drive position in the drive region and a locking position in the locking region.

A sliding door closure system is provided including close and energy harvesting to recover kinetic energy from the motion of the door. According to some embodiments, the relative motion between a sliding door and sliding door track may be configured to drive a generator. The generator may be driven by a driving a wheel rotationally connected to the generator. Examples include driving the generator by a friction wheel, by a chain and sprocket, or by a gear and rack. The generator may recover kinetic energy from the motion of the door during the deceleration of the soft close function. Energy recovered from the door may be stored and used to assist the motion of the door or to operate sensors to monitor the operation of the door closure system. The door closure system may transmit data and preserve a record of use.

At least one panel including a trolley is fed to a first drive mechanism of a plurality of drive mechanisms adjacent a main track configured to engage the trolley of the at least one panel. The first drive mechanism is initiated to drive the at least one panel to a second drive mechanism of the plurality of drive mechanisms to move the at least one panel farther along the main track.
