In example implementations, a horizontal door guide for a vertically stacking door is provided. The horizontal door guide includes a first track and a second track to vertically stack panels of a door along a horizontal line, a drive shaft coupled to a bottom most panel to lift the door vertically, a Geneva drive shaft coupled to the drive shaft, and a lifting cam coupled to the Geneva drive shaft, wherein the lifting cam comprises a rotating lever to separate and lift adjacent panels of the door as the door is opened in a vertical direction by the drive shaft and to push panels into the first track and the second track.

A cable guide assembly adapted for use with a guide rail for a motor vehicle, for redirecting a cable of a window regulator, includes a cable guide formed with an arc-shaped body having a cable guide groove on an outer perimeter of the arc-shaped body and a cable guide receiving site formed in the guide rail adapted to receive and mount the cable guide. The cable guide includes a cable holding tab extending outward from the arc-shaped body along a longitudinal axis and a pair of side hooks extending from an end portion of the arc-shaped body along a transverse axis. In an intermediate-installed state of the cable, the cable is set under the cable holding tab, and in a fully-installed state of the cable, the side hooks are configured to prevent the cable from coming off from the cable guide.

The overhead door lift assembly integrates a traditional torsion spring and an electrically powered operator into a small package mountable in the available head space of conventional tractor trailers, cargo vehicles or other structures. The lift assembly includes a torsion spring counterbalance, electrical operator, and back tension mechanism. The electrical operator uses an electromagnetic clutch and gearbox that couples directly to the cable drums of the counterbalance. The electromagnetic clutch allows the overhead door to be manually raised and lowered in the event of a power interruption or operator malfunction. The back tension mechanism prevents cables from inadvertently unspooling from cable drums as the operator starts to move the overhead door from its horizontal open position to its vertical closed position.

Provided is a cable routing structure in which a cable guide member includes a support portion including an edge portion on one side and an edge portion on another side, a first erected portion erected on a side of the edge portion on the one side, and a second erected portion erected on a side of the edge portion on the other side. The first erected portion includes an engaging portion engaging with a base member, the second erected portion includes a connecting portion connected to the base member, and a distance in which a linear portion that is intermediate between both ends of a cable is provided between the first erected portion and the second erected portion. The base member includes an engaged portion being engaged with the engaging portion of the first erected portion.

A door operator assembly is configured to raise and lower a cargo door of a cargo enclosure. The assembly includes a power and control unit mounted on an exterior of the cargo enclosure. The power and control unit includes a motor, a coupler operatively connecting the motor to a torsion assembly of the cargo door, a manual release mechanism for actuating the coupler to connect and disconnect the motor and the torsion assembly of the cargo door, and a control circuit for the motor. The assembly may also include an operating switch disposed on the exterior of the cargo enclosure.
