BACKGROUND OF THE INVENTION
1. Field of Invention
The Blakney Canopy Frame with Outdoor Canopies for Chair is a chair accessory. A sunshade, a mosquito or bug net, a blind or privacy screen, can all be draped over a chair and can be taken along as an extension of a folding chair to the beach or on a fishing trip. A very simple frame extends from a chairbag slipped over the back of a chair. The chairbag not only serves as the mechanism to attach the canopy frame, but also provides storage for the canopies.
2. Description of Prior Art
The problem of how to mount a canopy frame to a chair was solved by modifying a chairbag. A chairbag is a fabric sleeve that is slipped over the back of a chair and has a storage pouch in back. School children in Zimbabwe where the inventor grew up, used them to store books. Because my design allows for a number of canopies to be used and stored with a chair, this design challenges the prior art of a number of inventions—sunshade attachments for chairs, seating combined with outdoor blinds, and chair designs that add storage pouches. Patented inventions that use similar principles to apply canopies or to add storage to chairs are many, the application of sunshades to chairs is particularly common, but each inventor has combined different mechanisms and has emphasized different purposes.
D312,931 Westfall et al., “Sun Shade for a Lawn Chair of the Like,” has a similar box top shaped sunshade and similar frame shape but attaches to chair with clamps rather than chairbag attachment. It does not collapse and does not incorporate other canopies.
U.S. Pat. No. 3,990,536 Wilburn, “Portable enclosure” incorporates seating with blind, but is stiff and monofunctional and mechanically complex in comparison to my invention.
U.S. Pat. No. 4.083,601 McBeth, “Outdoor Chair” incorporates seating with blind/windbreak, but can not be collapsed against a chair back and is much more complex mechanically.
U.S. Pat. No. 4,687,249 Mills, “Adjustable canopy for a wheel chair, beach chair, and the like,” has a similar frame concept. Legs or arms slip into cylinders or tubes that are like the cylindrical sleeves of a chairbag, but Mills uses no crossbar for back of frame and uses a different mechanism for bracing and adjusting the top canopy support.
U.S. Pat. No. 4,788,997 Clopton, “Portable Blind” incorporates seating with blind, but has a much more complex frame and is mono-functional.
U.S. Pat. No. 4,924,896 Carter, “Collapsible canopy structure for use in association with a chair or other free-standing device,” has a much more elaborate framework for supporting a canopy.
U.S. Pat. No. 4,971,089 Braman, “Folding Shelter” incorporates seating with blind, but does not collapse with a chair and is mono-functional.
U.S. Pat. No. 5,096,257 Clark, “Sunshade apparatus for chair,” uses different bracing and attachment mechanisms and does not incorporate other canopies.
U.S. Pat. No. 5,102,190 Atkin et al, “Portable sun shade,” has a frame that uses a similar set of braces to attach the back and top of frame together, but has no crossbar for back and attaches by means of straps instead of sleeves. Atkin also uses a completely different frame back construction.
U.S. Pat. No. 5,154,473 Joranco “Chair with sun screen and windbreaker panel,” uses a similar sleeve attachment concept. An “inverted pocket which fits over the back of a chair”, but the pocket is not independent as is the chairbag and is attached directly to a windbreaker panel.
U.S. Pat. No. 5,203,363 Kidwell et al, “Portable canopy attachment.” The back of the frame is very similar with crossbar and legs, but the frame has a completely different mechanism to support the canopy and the invention does not incorporate multipurpose canopies.
U.S. Pat. No. 5,582,458 Wildt, “Portable Lounge Chair” incorporates the idea of adding storage pouch to the back of a chair, but does not incorporate multipurpose canopies and has a different mechanical structure.
U.S. Pat. No. 5,641,197 Springman, “Collapsible Sports Chair” is also a multipurpose invention, but with different purposes. Springman does not incorporate multipurpose canopies and uses a different mechanical structure.
U.S. Pat. No. 5,727,841, Morley “Removable Accessory for Lounge Chair” has a storage compartment as part of chair attachment and the frame can remain part of the chair when collapsed, but the attachment does not rise above the back of the chair and it does not have parts that can be exchanged.
U.S. Pat. No. 5,752,537 Kranzler's sunshade/windbreak provides an insect barrier, but it is freestanding and does not serve as a chair attachment.
U.S. Pat. No. 5,797,650 Gonzalez Jr., et al., “Sun shade attachment.” Much like Clark but even more complex, and is monofunctional.
U.S. Pat. No. 5,873,625 Uchtman “Folding chair with canopy.” Much like Carter this invention has a much larger framework to support a canopy.
U.S. Pat. No. 5,967,601 Gillins, “Sunshade apparatus for recreational chair,” uses similar rectangular U-shaped sections of frame, but they are attached and pivot with a different mechanisms. The frame collapses so that the top section is nested within the back section, rather than each section laying on top of each other as in my design.
U.S. Pat. No. 6,036,262 Shahid, “Carry-all-chair” uses the idea of adding storage to a chair, but does not incorporate multipurpose canopies and has different structural supports.
BRIEF SUMMARY OF THE INVENTION
The Blakney Canopy Frame with Outdoor Canopies for Chair provides a sunshade, mosquito or bug net, and a photography or changing blind for a chair. It is also portable, collapsing with or without a chair, and has a storage pouch for easy access to the canopies. Many inventors have designed chair extensions or attachments to support canopies, There are also chair designs that incorporate storage, and there are blind designs that incorporate seating. But, in comparison this invention is designed with minimal mechanism and with greater aesthetic application. No other design provides multipurpose, interchangeable canopies, readily stored, available, and portable. By combining many functions, and through simplicity of basic assembly design, this portable chair frame with matching canopies, surpasses all comparable inventions.
The problem of mounting a canopy frame to a chair has been solved in a completely unique way by using an independent fabric chairbag, instead of mechanical clamps or straps. When setting up canopies, or collapsing the frame for storage, no obtrusive parts can get caught on anything. The chairbag provides storage for canopies behind the chair's back, thereby not interfering with the folding mechanism of a chair. No other invention collapses completely with a variety of canopies for easy storage and transport either with or without a chair. No other invention has the aesthetic potential of this design. The frame, chairbag and canopies can all be coordinated with a chair to create a beautiful or romantic impression.
