Abstract
A retractable awning having a roller, a flexible canopy having one end secured to the roller and rollable onto the roller, and a motor operable to rotate the roller to roll the flexible canopy onto or off the roller. The motor includes a protective housing, with a manual motor override on the motor within the housing. An aperture in the housing proximate the override is aligned with and permits access to the override through the aperture.
Claims15
A retractable awning configured for mounting to a wall of a structure, the awning comprising:
- first and second support systems attachable to the wall, each of the support systems comprising a support arm having an end extendable from and retractable toward the wall;
- a housing attached to the end of the support arm of at least one of the first and second support systems;
- a motor and gearing disposed within and supported by the housing, the motor comprising a shaft and the gearing comprising a worm gear formed on the shaft, a worm wheel engaged with the worm gear, the worm wheel disposed on a spindle perpendicular to the shaft, a drive gear arrangement drivable by the spindle, and an output shaft drivable by the drive gear arrangement, a portion of the output shaft extending from the housing;
- a roller connected to and drivable by the output shaft, the roller having an axis of rotation;
- and
- a flexible canopy having one end secured to the roller and another end attachable to the wall, the canopy being rollable onto and unrollable from the roller;
- and
- a manual override disposed within the housing, the manual override comprising a connector capping the shaft, the connector comprising a connection head configured for connection to and rotation by a manual override tool, the manual override in constant engagement with the shaft;
- wherein the housing defines an aperture proximate and longitudinally aligned with the shaft and configured for insertion of the manual override tool there through;
- and
- the roller is configured to rotate about the axis of rotation in response to rotation of the manual override and to translate perpendicular to the axis of rotation in response to rotation thereof.

A method of manually operating a motor-operated awning configured for mounting to a wall of a structure and including:
- first and second support systems attachable to the wall, each of the support systems comprising a support arm having an end extendable from and retractable toward the wall;
- a housing attached to the end of the support arm of at least one of the first and second support systems;
- a motor and gearing disposed within and supported by the housing, the motor comprising a shaft and the gearing comprising a worm gear formed on the shaft, a worm wheel engaged with the worm gear, the worm wheel disposed on a spindle perpendicular to the shaft, a drive gear arrangement drivable by the spindle, and an output shaft drivable by the drive gear arrangement, a portion of the output shaft extending from the housing;
- a roller connected to and drivable by the output shaft, the roller having an axis of rotation;
- and
- a flexible canopy having one end secured to the roller and another end attachable to the wall, the canopy being rollable onto and unrollable from the roller;
- and
- a manual override disposed within the housing, the manual override comprising a connector capping the shaft, the connector comprising a connection head configured for connection to and rotation by a manual override tool, the manual override in constant engagement with the shaft;
- wherein the housing defines an aperture proximate and longitudinally aligned with the shaft and configured for insertion of the manual override tool there through;
- and
- the roller rotates about the axis of rotation and translates perpendicular to the axis of rotation in response to rotation of the manual override;
- the method comprising the steps of:
- inserting a manual override tool through the aperture;
- engaging the connection head with the manual override tool;
- operating the manual override tool to rotate the shaft and thereby rotate the roller;
- wherein the flexible canopy rolls onto or unrolls from the roller in response to the rotation of the roller;
- wherein the roller translates along a path perpendicular to the axis of rotation in response to the flexible canopy rolling onto or unrolling from the roller;
- and
- wherein the manual override tool translates along a path corresponding to the path of the roller.
