Abstract
A door opener for a roll-type door in a cargo van includes a shaft that is mounted for rotation within the cargo van body and is coupled with the door such that shaft rotation causes the door to move between opened and closed positions. The shaft is rotated by a motor that is mounted outside of the cargo van body and is coupled to the rotatable shaft by a drive system that extends through the cargo van body. This arrangement allows a relatively large conventional motor to be used without extending into the door opening or compromising the height of the door opening.
Claims14
In combination with a cargo van comprising a cargo van body, a door opening in the cargo van body, and a roll-type door movable between an opened position in which the door is positioned in the cargo van above the door opening, and a closed position in which the door closes the door opening, a door opener comprising:
- a shaft mounted for rotation within the cargo van body, said shaft coupled with the door such that shaft rotation causes the door to move between the closed and opened positions;
- a motor mounted outside the cargo van body;
- and
- a drive system extending through the cargo van body to couple the motor and the shaft such that rotation of the motor causes rotation of the shaft and movement of the door.
