Description

BACKGROUND

Technical Field

The present disclosure pertains to deployable coverings for objects and, more particularly, to canopy devices, systems, and methods, that enable selectable degrees of deployment and provide a fully folded configuration useful with vehicles and in connection with boat lifts.

Description of the Related Art

Canopies for objects, such as vehicles, are known. Typical canopies include a frame and a cover to provide a protected space under which to store an object or park a vehicle. The canopy frame typically extends vertically and horizontally to span an area such that when an object is placed under the canopy, the cover provides protection for the object from the sun, rain, or snow, among other environmental conditions. However, fixed or permanent canopies suffer from a number of drawbacks or disadvantages.

For example, the permanent shade created by fixed canopies is frowned upon in many jurisdictions because of the negative impact to surrounding ecosystems. Further, permanent canopies are not aesthetically pleasing and are typically viewed negatively by homeowners or neighbors. These problems are exacerbated when fixed canopies block waterfront views, or other scenic landscape views. Moreover, designing canopy covers and frames to handle snow and wind loads requires use of expensive and bulky parts, which increases cost for the consumer. Because fixed canopies are suspended above an area, most fixed canopies also do not provide adequate protection against environmental conditions impinging on the object or vehicle underneath the canopy from different angles, such as from the side. Such canopies are also not adjustable, meaning that the area covered by the canopy is fixed based on the size and arrangement of the frame, which limits use applications.

Some of the above issues are alleviated with removable canopy covers, but such canopy covers are typically formed from heavy material and are burdensome or cumbersome for the owner to manipulate on and off of the frame. Other solutions include covers that extend laterally toward the support surface to provide protection to the sides of an object under the canopy, but such solutions do not address the environmental or aesthetic concerns mentioned above and are also not adjustable. As such, current canopies suffer from a number of disadvantages, as do available proposed solutions.

In one implementation, the retractable canopy 20 includes at least one second strut 36 rotatable relative to the fixed boom 24 and at least one third strut 38 supported by the movable boom 26. A cover 40 is secured at a first end 42 to the fixed boom 24 and at a second end 44 to the movable boom 26.
