The present invention relates to privacy screens, more particularly to outdoor, manually moveable, decorative, sunlight mitigating, and wind resistant, space-dividing partitions that offer easy assembly for both residential and commercial environments.
As urban populations grow and the trend for outdoor living becomes a staple for homeowners and renters alike, the need for out-of-doors privacy has never been greater. The U.S. Census Bureau reports that as of 2012, 80.7 percent of the population resided in urban areas. Moreover, while homes have been increasing in size, lots have been decreasing. Similarly, the Apartment and Condominium Construction industry has been experiencing one of the fastest expansions within the construction sector. In their personal landscapes, everywhere, people are in closer proximity to one another and in need of privacy.
Also, there is a trend to bring the indoors, out, by creating outdoor landscapes that are well-designed, comfortable retreats. In 2016, The Institute of Architects reported that the outdoor living market expected to top $7.1 billion by 2020. Consumers desire relaxing, personal spaces with lighting and furnishings, including privacy partitions that decoratively enhance views or, in some cases, screen undesirable vistas.
Important, too, for outdoor living is a means to limit exposure to skin cancer-causing, ultraviolet (UV) rays. Identifying adequate shading devices for outdoor living environments is a concern.
Taking advantage of these outdoor spaces on fair-weather days means that privacy, decorative, and at least partially sun-shielding privacy screens are required to function in breezes and winds that often arise on the sunniest occasions. Outdoor space-dividers need to be wind resistant and stable under such conditions.
There exists, across industries, a variety of devices that include parts addressing the aforementioned needs relative to an effectively functioning outdoor privacy screen. However, no product or disclosure addresses all of these requirements in a single, successful invention.
Prior art discloses outdoor, manually moveable and portable privacy screens, windscreens, and sunshades, among others. Privacy is usually achieved by tensioning one or more, large, flexible i.e., fabric panels to a frame. However, tensioned panels are not wind resistant and in breezy conditions, such screens become unstable. And, recommendations for leg bracing via sandbags or other weights is unwieldy and unattractive. In addition, although large, flexible panels may be removable from their frames, they are costly to replace, difficult to clean, and offer fewer design alternatives than the smaller, easily removable panels of the present invention. U.S. Pat. No. 5,553,648 (Goharjou; Sep. 10, 1996) discloses a portable wall system with flexible sheet half-moon cut flaps. However, wind slits are negligible in wind force abatement.
Fixed, e.g., bolted down, clamped on, etc., outdoor deck partitions and balcony shields exist in prior art. These types rely on the structural integrity of their foundations or supports for stability. Compromised deck flooring or balcony railing inhibits the safe functioning of these types. And, unlike the present invention, fixed types lack mobility to provide light deflection as the sun changes position throughout the day. U.S. Pat. No. 6,513,566 B2 (Larin; Feb. 4, 2003), discloses a balcony railing-affixed shielding device with two flexible panels.
Outdoor, wind-resistant, multi-panel products exist in prior art such as traffic shields and fence products. These barriers are unrelated to the functional privacy the present invention assumes. U.S. Pat. No. 8,973,645 B1 (Cannova; Mar. 10, 2015) discloses a portable wind-resistant traffic screen wherein “The screen partially disengages . . . for the purpose of reducing wind pressure . . . .”
Devices with flexible fabric, louver-arranged panels for permitting airflow, and wind resistance, where the lamellae are not interconnected for motion, exist ranging from windbreakers to insect screens. However, prior art discloses no invention that allows air to pass between flexible-fabric louver-arranged panels ensuring resistance to wind gusts such as the present invention assumes. U.S. Pat. No. 4,432,381 (Greenbaum; Feb. 21, 1984) discloses a windbreaker secured to a frame.
Prior art discloses indoor, space-dividing privacy partitions with flexible frame covers typically designed for venues such as: offices, hotel rooms, and, production facilities. Prior art reveals no invention incorporating both mobility and a decorative mix-and-match, multi-panel function such as the present invention assumes. U.S. Pat. No. 6,354,043 B1 (Simon et. al, Mar. 12, 2002) discloses an office partition of draped fabric panels reliant on a fixed frame.
Prior art reveals inventions incorporating quick-release snap fasteners for attaching flexible sheets to solid substrates in devices such as boat covers and display frames among others. No prior art reveals a quick-release, panel fastening system such as the present invention assumes. U.S. Pat. No. 4,471,548 (Goudie; Sep. 18, 1984) discloses a display frame wherein snap fasteners work in conjunction with stabilizing flat bar (see
The present invention's features are easily distinguishable from these and other devices. None of the above devices, taken either singly or in combination, provides a privacy screen for outdoor, residential and commercial use such as the present invention assumes.
The present invention was developed of tubular aluminum, solid aluminum bar, solid steel foot components, and fabric panels for a free-standing and stable; manually moveable; easily assembled frame incorporating releasably-fastened, frame-attached elements suspending a series of mix-and-match, flexible, louver-arranged panels that afford privacy, mitigation of sunlight, and an allowance for air flow thus creating a wind resistant privacy screen.
It is the object of the invention that the privacy screen be both for residential and commercial use.
It is another object of the invention that the privacy screen affords stability and wind resistance by incorporating weighted base foot components.
It is another object of the invention that the privacy screen affords stability and wind resistance by arranging fabric panels in an airflow-permitting louver configuration.
It is another object of the invention that the privacy screen is manually moveable and easy to assemble.
It is another object of the invention that the privacy screen affords concealment by fastening and suspending fabric panels in louver arrangement.
It is another object of the invention that the privacy screen mitigates harmful UV sunlight by partially accommodating the changing angle of the light throughout the day by means of screen mobility and ultraviolet-ray protective, fabric panels.
It is another object of the invention that fabric panels for outdoor screen use be constructed of standard outdoor awning or woven PVC coated polyester fabric.
It is another object of the invention that the privacy screen enable decorative function flexibility by incorporating multiple, detachable, interchangeable, and replaceable fabric panels that are easy to maintain and cost effective to replace.
It is another object of the invention that the privacy screen be available with quick-release snap fasteners that secure metal bar held fabric panels to vertical tube members of said structural frame.
It is another object of the invention that the privacy screen be modular by enabling outer edge vertical members of one screen to fit snugly to side-by-side outer edge vertical members of one or more additional screens.
The present invention is a single structure frame with foot components and comprised of: metal tubing, square bar, and plate; bolts; bolt-less right angle connectors; retractable-pin spring-clip fasteners; grip knobs; quick-release snap fasteners; and, frame-detachable metal flat bars that support hanging, flexible fabric privacy panels.
The privacy frame panels are made of non-transparent, ultraviolet-ray protective, solution-dyed acrylic awning or PVC coated polyester mesh fabric. Panel fabrics are easy to clean; and, sun and mildew resistant.
When assembled, the privacy frame is supported by two sets of solid-metal, foot components i.e., a base plate with welded arch and bolted foot post; frame-attached by sliding said post into the lower frame vertical tube bottom end and securing said post, tube, and arch by a hand-tightened grip knob. A second set of foot components is likewise secured to a second vertical tube bottom end. Spring-clip fasteners inserted into lower frame vertical tube upper ends are in turn spring-clip fastened to two longitudinal tube frame member lower ends. Longitudinal frame tubes are thus connected to the lower frame section.
Spring-clip fasteners are then inserted into two longitudinal tube frame member upper ends that in turn spring-clip to upper frame vertical tubes. The rectangular frame with foot components is thus assembled. Five fabric panels are then hem-slid onto five metal flat bars. Each metal flat bar is independently, quick-released fastened to the frame face at regular intervals.
The assembly of the invention is comprised of approximately eight simple steps including base feet assembly, i.e., bolting foot posts to base plates; connecting foot posts and base plate arches to the lower frame section via hand-tightened grip knobs; spring-clip fastening longitudinal side tubes to both the lower and upper frame tube sections; sliding fabric panels over respective metal flat bars; and, quick-release fastening metal flat bars to said frame.
By way of example, reference will now be made to the accompanying drawings, which are not to scale.
The same reference numbers will be used throughout the drawings and the following description to refer to the same or like parts.
A problem in the market exists that there is no outdoor, independently stable, easily moveable, space-dividing residential and commercial privacy screen that offers within a single invention, sunlight mitigation, wind resistance; and, interchangeable, cost effective, decoratively changeable, louver configured, releasably-fastened, flexible panels. The various embodiments of the privacy screen herein are designed for outdoor residential and commercial use. However, the screen may be utilized to accommodate indoor privacy needs as well. For example, in addition to outdoor residential use on patios, decks, and in the landscape, among other locations, the screen may be used indoors to provide privacy within rooms and spaces where division, retreat, or a measure of solitude is desired. Consumers may select among a variety of frame, panel colors, and materials dependent upon preference and application.
Commercially, the privacy screen may be used outdoors in a variety of venues where some measure of separation from others is preferred. Outdoor seating for coffee shops and restaurants are primary examples. Indoor use might include situations where pharmacies arrange client privacy and retail stores provide fitting space partitions. Commercial organizations may incorporate their identities on screen frame panels as well as determine frame and panel colors. In all cases, both out-of-doors and indoors, the privacy screen is designed to be multi-functional, visually pleasing, high quality, and of moderate cost to consumers.
