The presently disclosed subject matter is generally directed to a wind-resistant umbrella comprising a mesh layer and a series of shingles that effectively dissipates wind gusts, providing for safe use.
Beach umbrellas are used to create an area shaded from the sunlight beneath the umbrella canopy. Umbrellas are particularly useful at the beach where there is generally a lack of trees or roofed structures to provide shade. Because the skin of the beachgoer is largely exposed at the beach, there is a greater need to provide protection from harmful ultraviolet rays, which may cause sunburn or melanomas. Many beachgoers also require some form of shade to minimize heat discomfort. The shade and shelter provided by a beach umbrella is also useful in protecting the user's valuables and shielding perishable items from direct sunlight. Conventional beach umbrellas include a single central support pole with a pointed lower end that is inserted directly into the sand. Conventional umbrellas further include a bell-shaped canopy via a framework comprising a series of expanding ribs.
However, because beach umbrellas are light, and the canopy has a large surface area, a gust of wind or a relatively light breeze can generate a lifting force and pull the umbrella pole out of the ground. As a result, the beach umbrella is no longer secure, and can easily be lifted out of the sand and blow away, causing serious injury to other beachgoers and damage to property. To this end, every year there are injuries and even deaths associated with beach umbrella accidents, most of which are caused by beach umbrellas dislodging from sand due to high-speed winds.
Attempts have been made to reduce the effects of wind gusts on beach umbrellas. For example, beach umbrellas equipped with a small venting canopy fixed on top of a larger, main canopy have been developed. Such a system works with low-speed winds below about 15 mph but fails when wind gusts are increased. Screw-in augers have also been used to bury the umbrella support pole in the sand in an effort to resist wind gusts. Nonetheless, strong wind gusts in excess of about 20 mph can exceed the strength of the auger, dislodging the beach umbrella from the sand with little or no warning. Wind tunnel testing of conventional umbrellas shows that conventional umbrellas cannot resist repeated or sustained wind gusts in excess of about 20 mph without dislodging or becoming otherwise unusable.
Accordingly, it would be beneficial to provide a wind-resistant umbrella for dissipating wind gusts to preclude the umbrella from being dislodged from its position and being blown down the beach, thereby ensuring a safe beach environment.
In some embodiments, the presently disclosed subject matter is directed to a wind-resistant umbrella defined by a vertical support pole. The umbrella further includes a canopy attached to an upper end of the support pole. The canopy comprises a lower mesh layer defined by an upper surface and an opposed lower surface, and an upper layer comprising a plurality of shingles, wherein each shingle is defined by an upper surface, an opposed lower surface positioned adjacent to the mesh layer upper surface, and one or more apertures positioned adjacent to a top shingle edge. The canopy also includes a plurality of upper grommets, each upper grommet comprising a lower surface defined by one or more arms that extend away from the lower surface, wherein the lower surface of each upper grommet is positioned adjacent to the upper surface of a shingle and wherein the one or more upper grommet arms extend through the one or more shingle apertures. The canopy further includes a plurality of lower grommets, each lower grommet comprising a top surface and an opposed bottom surface, and one or more openings sized and shaped to accept the one or more arms to join a corresponding upper grommet to the lower grommet, wherein the top surface of each lower grommet is posited adjacent to the mesh layer lower surface. The top edge of each shingle is adhered in position on the umbrella through the upper and lower grommets; and a bottom edge of each shingle is non-adhered to the umbrella and freely moves in an upward direction in response to air currents.
In some embodiments, the shingles are arranged in the upper layer in an overlapped configuration whereby one shingle partially covers at least one other shingle.
In some embodiments, the umbrella further includes a top cap positioned at the top end of the support pole, above the shingles.
In some embodiments, each shingle comprises two apertures positioned at the top edge of the shingle.
In some embodiments, each arm releasably attaches to a corresponding opening.
In some embodiments, each shingle has a length, width, or both of about 3-10 inches.
In some embodiments, the shingles are constructed from a flexible material.
In some embodiments, the shingles are constructed from one or more waterproof materials.
In some embodiments, the umbrella includes an anchor positioned at a second end of the support pole.
In some embodiments, the umbrella comprises a support frame positioned below the mesh layer.
In some embodiments, the frame is defined by a plurality of ribs, cross-ribs, or both.
In some embodiments, the presently disclosed subject matter is directed to a method of precluding dislodgment of a wind-resistant umbrella from an anchoring location. Specifically, the method comprises positioning a wind-resistant umbrella in the anchoring location (e.g., the lower support pole end in the ground, in the sand, etc.). The wind-resistant umbrella is defined as a vertical support pole and a canopy attached to an upper end of the support pole. The canopy comprises: a lower mesh layer defined by an upper surface and an opposed lower surface; an upper layer comprising a plurality of shingles, wherein each shingle is defined by an upper surface, an opposed lower surface positioned adjacent to the mesh layer upper surface, and one or more apertures positioned adjacent to a top shingle edge; a plurality of upper grommets, each upper grommet comprising a lower surface defined by one or more arms that extend away from the lower surface, wherein the lower surface of each upper grommet is positioned adjacent to the upper surface of a shingle and wherein the one or more upper grommet arms extend through the one or more shingle apertures; a plurality of lower grommets, each lower grommet comprising a top surface and an opposed bottom surface, and one or more openings sized and shaped to accept the one or more arms to join a corresponding upper grommet to the lower grommet, wherein the top surface of each lower grommet is posited adjacent to the mesh layer lower surface. The top edge of each shingle is adhered in position on the umbrella through the upper and lower grommets; and a bottom edge of each shingle is non-adhered to the umbrella and freely moves in an upward direction in response to air currents. The method includes exposing the wind-resistant umbrella to windy conditions, such that air freely flows from the lower side of the mesh layer, through the mesh layer, to push against the bottom edge of one or more shingles, thereby moving the bottom shingle edges to create an exit for the air, wherein the wind-resistant umbrella is precluded from dislodging from the anchoring location.
In some embodiments, the bottom edge of the shingles returns to contact the mesh layer when the air flow is removed.

It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
The presently disclosed subject matter is generally directed to an umbrella comprising a plurality of shingles attached to a webbed or mesh support. As shown in
As shown in the cutaway view of
As shown in
In some embodiments, the mesh can be constructed from any suitable material, such as (but not limited to) nylon, polyethylene, polyester, polypropylene, Teflon®, woven plastic, metal (e.g., copper, chromium, iron, nickel, titanium, tungsten), glass, silicon carbide, fiberglass, graphite, carbon fiber, or combinations thereof.
The umbrella canopy further includes an upper layer comprising a plurality of shingles 10 positioned adjacent to top face 40 of the mesh in an overlapping arrangement, as illustrated in
Apertures 50 cooperate with upper and lower grommets 55, 56 to securely anchor the top edge of each shingle in place on the umbrella. The term “grommet” refers to a component that can be attached on either side of a shingle to maintain the shingle in proper position. As shown in
Thus, upper grommet 55 permanently or releasably attaches to lower grommet 56 by passing through shingle apertures 50 and mesh layer 15, as shown in
The first row of shingles 70 can be fastened beginning on the bottom edge of the mesh layer, as shown in
Each shingle includes length 60, width 61, and thickness 62. The term “length” refers to the longest horizontal straight line distance of shingle 10. The term “width” refers to the distance perpendicular to the length. The term “thickness” refers to the distance between the top and bottom faces of the shingle. Each shingle can include length and/or width of about 3-10 inches (e.g., at least/no more than about 3. 3.5. 4. 4.5. 5. 5.5. 6. 6.5. 7. 7.5. 8. 8.5. 9. 9.5. or 10 inches). It should be appreciated that the presently disclosed subject matter is not limited and the shingle can be configured with any desired size and shape.
Shingle 10 can further be configured in any desired shape, such as (but not limited to) square, rectangular, oval, triangular, and the like, as shown in
Grommets can be constructed from any suitable material, such as (but not limited to) wood, metal, plastic, carbon fiber, fabric, and the like.
Shingles 10 can be constructed from any suitable material, such as (but not limited to) plastic, vinyl, cloth, or polyester, canvas, acrylic, polyvinyl chloride (PVC), nylon, polyester-nylon blend, marine-grade vinyl, silk, rayon, combinations thereof. In some embodiments, the shingles are constructed from a flexible material that is capable of undergoing strain, such as bending or stretching without being damaged or broken. In some embodiments, the materials used to construct shingles 10 can be waterproof (e.g., a material that prevents or impedes the entry/ingress of water). The material used to construct shingle 10 can further be easy to clean and can prevent growth of mold and mildew or sun bleaching.
The disclosed shingles are both decorative and functional. For example, shingles 10 serves to provide shade to a user and also can keep the umbrella canopy from leaking. Shingles 10 can also be configured in any suitable colors and patterns. For example, the shingles can be constructed in any suitable color or combination of colors to correspond to a desired sports team (e.g., in red and white). The colored shingles can also be positioned in any desired pattern (e.g., stripes) or to spell out words (e.g., college team names or abbreviations, phrases, names, and the like).
Umbrella 5 further includes post 25 with anchor 30 that maintains the umbrella in a support surface (e.g., sand).
Post 25 can have any desired cross-sectional shape. For example, the post can be configured with a circular, oval, square, rectangular, triangular, pentagonal, hexagonal, octagonal, heart, diamond, or abstract cross-sectional shape.
Second end 61 of the post is operatively connected to anchor 30. The term “anchor” broadly refers to any element that provides weight and/or a mechanism by which to secure assembly 5 into a support surface (e.g., sand). The anchor can be permanently attached to post 25 using adhesives, welding, and the like. Alternatively, the anchor can be releasably attached to the post using any of a wide variety of mechanical elements (e.g., screw knob, clip). A releasably attached anchor allows for the replacement of the anchor depending on use conditions (e.g., beach sand versus grass or rock). In some embodiments, the anchor can include a spike, helical corkscrew, or shaft with a threaded portion capable of being turned and embedding itself into a support surface (e.g., sand at a beach). Because anchor 30 is inserted into a support surface, it does not rotate and remains in the inserted position until the user desires to remove it. Likewise, the post does not rotate in response to wind conditions due to its attachment to the anchor.
In some embodiments, umbrella 5 can include a frame comprising a series of ribs 80 and/or cross-ribs 81 positioned on lower side 41 of mesh 15, as shown in
Cap 20 can be attached to the first end 62 of post 25 using any known method. For example, a screw, bolt, or other element can be threaded through the cap, extending into the post. Cap 20 can be configured in any desired shape and/or size (e.g., a diameter of about 6 inches in some embodiments), as shown in
In use, the disclosed umbrella can be used to provide shade safely and securely to one or more users. Anchor 30 can be positioned in a support surface, such as sand at the beach. In some embodiments, the post can be manually rotated to insert the anchor into the ground. Once the umbrella has been securely positioned in the ground, users can relax under the shade provided by the shingles. Even on windy days, the wind passes over and between the shingles, thereby preventing the umbrella from becoming dislodged from the ground, as illustrated in
The disclosed assembly therefore offers many advantages over prior art umbrellas. For example, umbrella 5 provides for increased wind flow through mesh 15 and between the shingles. In this way, uprooting of the umbrella is avoided. As a result, the umbrella stays in the original position until desired by the user, thereby preventing breakage, damage to the umbrella, and/or injury to beachgoers.
Umbrella 5 is easy to use and can be enjoyed by a wide variety of users, from children to the elderly.
The disclosed umbrella is windproof, and therefore will not launch into the air as a projectile on windy days due to the provided air flow through the mesh and between the shingles.
Umbrella 5 can be configured in any suitable shape and/or size, such as conventional round umbrellas as well as square, rectangular, and other shaped designs. In addition, the umbrella can be configured for a single user or sized for multiple users.
The disclosed umbrella comprises a single post, so it is universally permitted on beaches where tents are not.
Umbrella 5 is configured to be lightweight in construction and easily movable to a desired location.
Umbrella 5 is capable of withstanding a variety of weather conditions, including wind resistance.
The canopy of the disclosed umbrella is capable of being made with a variety of shingle sizes.
The disclosed umbrella can be capable of withstanding winds in excess of 10, 20, 30, 40, 50 or more miles per hour. Traditional umbrellas composed of frames made of metal or wood, will fail when subjected to similar wind conditions.
As described above, although a preferred embodiment of the present invention has been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions, and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
