The subject matter of the present disclosure refers generally to a system that may act as a shelter from the elements in windy conditions.
As tents and pop-up canopies have become lighter and less expensive, it is becoming increasingly common for beachgoers to bring them as shelter should a storm surprise them or as a temporarily escape from the sun. However, tents and pop-up canopies tend to affect the beauty of the surround area by acting as an impenetrable wall through which no one can see. Additionally, trashed tents and pop-up canopies have become a major source of frustration for many municipalities since beachgoers often leave broken pop-up canopies and tents at the site in which they broke. This trash can create a danger to beachgoers since many of these tents and pop-up canopies contain metal that could potentially pose tetanus risks should an unsuspecting beachgoer step on a buried piece of the metallic trash. It can also pose problems for wildlife since the tensile material may act as a net from which wildlife may have trouble escaping.
One of the primary reasons current tents and pop-up canopies break is due to drag forces created by wind acting on the tensile materials. This is particularly true at the beach where winds often reach more than twenty miles per hour. The supporting structures of many tents and pop-up canopies are simply not designed to withstand much force, and in those types of conditions, the tensile materials act very much like parachutes, subjecting the frames to more force that originally designed. Even if the tents and pop-up canopies are designed to withstand more forces than the average tent/pop-up canopy are designed to withstand, the structures are often not designed to withstand forces in the way wind may apply them. This results in the destruction of the underlying structure, resulting in beachgoers leaving them behind as unsightly and potentially dangerous trash for others to collect. Even if the tent and pop-up canopies don't break, they still may be prone to flipping in windy conditions due to the drag forces acting on the tensile materials. These types of scenarios can lead to shelters taking flight with the wind and present a danger to surrounding people and property. Further, wind resistant tents currently known in the art are either wind-supported (and thus do not provide equal functionality on a windless day) or are not large enough to host multiple standing people.
Accordingly, there is a need in the art for a canopy system that may be subjected to large gusts without sustaining damage, present a low flyaway risk, and provide shelter with or without the presence of wind while limiting obstruction of the surrounding scenery.
A system for a dynamically orienting adjustable shelter is provided. Generally, the system of the present disclosure is designed to provide the user a shelter in the form of a canopy that may protect the user from the elements during both windy and non-windy conditions. Alternatively, the system may be used as a portable shelter for rainy conditions in areas in which no or limited shelter may be available. The system generally comprises a base, lever arm, counterweight, boom, canopy, canopy supports, and support cables connected to said canopy supports. In one preferred embodiment, the system may further comprise a boom extension that may increase the length of the boom. In another preferred embodiment, the system may further comprise a plurality of tension straps that may be used to adjust the angle of the canopy supports.
The base comprises an extruded shape having a first end and a second end. In a preferred embodiment, the extruded shape is a cylinder. An outer wall of the base comprises a first aperture configured to fit a base end of the lever arm and second aperture configured to fit a bottom end of said boom. The lever arm connects to the base at said base end and a weight end extends away from said base such that the center of gravity of a counterweight attached to said weight end is in a position extending outward from and approximately central to a central point of said base. The counterweight preferably has a weight sufficient to overcome the torque created by the drag force acting on the canopy, the canopy weight, and the boom with the torque created by itself and the lever arm, wherein the drag force at a certain wind velocity may become large enough such that the torque created by the counterweight and lever arm may be overcome and the base may rotate the canopy back and eventually down.
The boom connects to the base at said bottom end and a canopy end extends away from said base at an angle from said lever arm that may allow a canopy support to be supported at an elevated position. In a preferred embodiment, the system comprises a first boom and second boom that functionally connects to said canopy support on a first side and second side. In a preferred embodiment, the canopy supports are attached to the boom in a way that allows it to rotate about said boom. By attaching the canopy support in this manner, the system may automatically adjust to windy conditions by allowing the canopy to naturally reduce the wind drag by causing the canopy support to rotate about the booms, which reduces the cross-sectional area of the canopy exposed to the wind. A cable may be attached to the front end of the canopy supports, which may prevent the back end of the canopy from tipping too far down when there is no wind that the system may use to stabilize the canopy by naturally reducing the cross-sectional area exposed thereto.

The system 100 generally comprises a base 105, lever arm 110, counterweight 115, boom 120, and canopy assembly 125. In one preferred embodiment, the system 100 may comprise cables 130 that may prevent the back end of the canopy assembly 125 from tilting too far down in conditions in which wind speeds are not high enough to allow the canopy 125B to be naturally supported in an upright position 600 by the wind. In another preferred embodiment, the system 100 may comprise a boom extension that may increase the length of the boom 120. In yet another preferred embodiment, the system 100 may comprise a plurality of tension straps that may be used to alter the amount of stress placed on the booms 120 as well as help adjust the angle of the canopy 125B. Although the system 100 disclosed herein has been discussed in terms of use for shelter in remote locations, one of skill in the art will appreciate that the inventive subject matter disclosed herein may be utilized in other fields or for other applications in which shelter may be needed. For instance, the system 100 could be used in tandem with outdoor furniture distributed about an outdoor pool area.
As illustrated in
In a preferred embodiment, a first aperture configured to fit a base end of the lever arm 110 and a second aperture configured to fit a bottom end of said boom 120 are spaced such that said lever arm 110 and said boom 120 form an angle between 90 and 110 degrees. Other embodiments may form an angle between the lever arm 110 and boom 120 that is less than 90 degrees so that the center of gravity of the counterweight is over the fulcrum of the base 105 when the canopy 125B is in a grounded position 200, as illustrated in
The lever arm 110 connects to the base 105 at said base end and extends away from said base 105. In a preferred embodiment, a lever arm 110 attaches to the base 105 via a first aperture located at a central point having an equal distance from the first end and second end of said base 105. The lever arm 110 preferably connects to said base 105 at approximately a 90-degree angle such that the center of gravity of a counterweight 115 attached to a weight end of said lever arm 110 is in a position extending outward from and approximately central to a central point of said base 105. Alternatively, a plurality of lever arms 110 may be positioned about said base 105 such that the center of gravity of a plurality of counterweights 115 attached to said plurality of lever arms 110 is in a position extending outward from and approximately central to a central point of said base 105. Materials that may be used to construct the lever arm 110 include, but are not limited to, polymer, aluminum, iron, steel, carbon fiber, wood, fiberglass, or any combination thereof.
In one preferred embodiment, the lever arm 110 is curved and/or angled such that the angle made between the counterweight 115 and boom 120 is less than 90-degrees. Should the canopy 125B and canopy support 125A contact the ground due to winds placing a larger drag force on the system 100 than the torque generated by the lever arm 110 and counterweight 115 can balance, the weight of the counterweight 115 will place a downward force on the boom 120 that may prevent the system 100 from assuming an upright position 600, thus locking the system 100 in this position. A user may reset the system 100 by moving the lever arm 110 and counterweight 115 until the weight of the counterweight 115 is no longer directly over said boom 120, which may allow the system 100 to reassume an upright position 600. Alternatively, the lever arm 110 may be curved and/or angled such that the angle made between the counterweight 115 and boom 120 is greater than 90-degrees, which may prevent the center of gravity of the counterweight 115 from crossing over the rotational fulcrum of the base 105. This may allow the system 100 to resume an upright position 600 when the drag force on the canopy 125B is lowered to a point that the torque created by the drag force acting on the canopy 125B, the canopy weight, and the boom 120 is less than or equal to the torque created by the counterweight and the lever arm 110.
The counterweight 115 attaches to the weight end of the lever arm 110 and creates a torque that acts on the system 100 as a balance to any drag force acting on the canopy 125B. In a preferred embodiment, the counterweight is a container made from a flexible material and configured to hold a substance, such as rocks, dirt, or sand. Because the torque generated by the lever arm 110 and counterweight 115 depends on both the length of the lever arm 110 and the weight of the counterweight 115, the weight of the counterweight 115 may vary. Generally, the weight of the counterweight 115 must be sufficient to balance the drag force acting on the canopy 125B and the weight of the canopy 125B so that the canopy assembly 125 may adjust about the boom 120 to expose the smallest cross section of the canopy 125B to the wind as possible, as illustrated in
In another preferred embodiment, the counterweight 115 may be incorporated into the lever arm 110 such that the lever arm 110 and counterweight 115 are a single unit. For instance, a lever arm 110 having a length of three feet and weight of twenty-five pounds may have a center of gravity that is significantly skewed towards the weight end so that the weight end may act as a counterweight 115 for the system 100. In yet another preferred embodiment, the counterweight 115 may comprise a container that may be filled with a substance, which may allow a user to reduce the weight of the counterweight 115 while the user is transporting the system 100 to a desired location and increase the weight when the user assembles the system 100 by filling the container with said substance. For instance, a user may transport the system 100 to a beach and then fill a container with sand once they have reached a desired location. When the user is ready to break down the system 100, the user may empty the container for easier transport.
In yet another preferred embodiment, a second counterweight 115 may be attached to the back end of the canopy assembly 125, as illustrated in
The boom 120 attaches to the base 105 at said bottom end and extends away from said base 105. In one preferred embodiment, the boom 120 is foldable and comprises a plurality of tubular sections arranged about an elastic cord, wherein said tubular sections have interlocking ends that allow said tubular sections to be combined to create a single boom 120. In another preferred embodiment, the boom 120 is telescoping to minimize the space occupied by the boom 120 when not in use. The telescoping boom 120 may be locked into a plurality of lengths, allowing a user to adjust the height of the canopy assembly 125 by adjusting the height of the boom 120. This also may affect the torque created by the drag force acting on the canopy 125B, the weight of the canopy 125B, and the boom 120 since the reduced/increased length of the boom 120 will reduce/increase the amount of torque, respectively. In another preferred embodiment, a user may adjust the height of a first boom 120 higher than the height a second boom 120, which may cause the canopy 125B to no longer be generally parallel with the ground, as illustrated in
Materials that may be used to construct the boom 120 include, but are not limited to, polymer, aluminum, iron, steel, carbon fiber, wood, fiberglass, or any combination thereof. In a preferred embodiment, a first boom 120 and a second boom 120 attach to the base 105 via a first boom 120 aperture and second boom 120 aperture having x, y, z coordinates that differ only in the value of z, wherein the z-axis extends centrally through said base 105 from said first end to said second end. The first boom 120 apertures and second boom 120 aperture are preferably located equal distances from the first end and the second end of the base 105 so that drag force acting on the base 105 via the canopy 125B through the canopy support 125A and boom 120 generally creates a force vector that is located about a central plane of said system 100. The angle created by said boom 120 and said lever arm 110 allows the canopy support 125A to be supported at an elevated position at a canopy 125B end of said boom 120.
The canopy assembly 125 may comprise a canopy 125B and canopy supports 125A. The canopy 125B may be defined as a tensile structure that may provide shelter when attached to the canopy supports 125A. The canopy supports 125A may be defined as rigid beams to which a canopy 125B may be attached. In a preferred embodiment, the canopy supports 125A comprise a first canopy support 125A attached to a first side of said canopy 125B and a second canopy support 125A attached to a second side of said canopy 125B. Materials that may be used to make the canopy supports 125A include, but are not limited to, polymer, aluminum, iron, steel, carbon fiber, fiber glass, wood, or any combination thereof. In a preferred embodiment, the canopy supports 125A are foldable and comprise a plurality of tubular sections arranged about an elastic cord, wherein said tubular sections have interlocking ends that allow said tubular sections to be combined to create a single tubular support. In another preferred embodiment, the canopy supports 125A may be telescoping. Materials that may be used to make the canopy 125B include, but are not limited to, mesh, nylon, polyester, cotton, canvas, or any combination thereof. In a preferred embodiment, the canopy 125B is water-resistant or water-proof such that it may provide protection from the elements when in wet conditions. In another preferred embodiment, the canopy 125B may have an ultraviolet protection factor (UPF) such that it may provide protection from ultraviolet light in sunny conditions.
The canopy supports 125A are preferably attached to the canopy 125B via a plurality of attachment elements situated about the length of the canopy supports 125A. In a preferred embodiment, the width of the canopy assembly 125 is less than the width of the space between the canopy 125B ends of the first boom 120 and second boom 120. When the first canopy support 125A is connected to the first boom 120 and the second canopy support 125A is connected to the second boom 120, the stress placed on the first boom 120 and second boom 120 force the first canopy support 125A and second canopy support 125A away from one another, which in turn cause the canopy 125B to become taut. In a preferred embodiment, the canopy assembly 125 is attached to the boom 120 via an attachment element. In an alternative embodiment, a single boom 120 attached to the base 105 via a centrally located single boom 120 aperture may attach to a bracket of canopy 125B. A plurality of batten sleeves of the canopy 125B may allow for canopy supports 125A in the form of battens to be inserted into the canopy 125B to make the canopy 125B taut. Alternatively, a “T” rod connecting the central boom 120 to the canopy supports 125A could be used to push apart the canopy 125B rods, causing the canopy 125B to become taut.
As illustrated in
In a preferred embodiment, tension straps connecting the canopy supports 125A to said attachment elements may allow a user to increase or decrease the stress on the booms 120 by increasing or decreasing the length of the tension straps, which in turn may increase or decrease the width of the canopy assembly 125. For instance, by increasing the length of the tension straps, a user may increase the total width of the canopy assembly 125 such that it is wider than the distance between the first boom 120 and second boom 120. This in turn decreases the stress acting on the first boom 120 and second boom 120 since first boom 120 and second boom 120 are no longer bent towards one another. In another preferred embodiment, tension straps connecting the booms 120 to said attachment elements may further allow a user to increase or decrease the stress on the first boom 120 and second boom 120 in the same manner as above.
The first boom 120 and second boom 120 are preferably attached to the canopy supports 125A of the canopy assembly 125 at an attachment point off center and towards the front end of the canopy assembly 125. Should the weight of the canopy assembly 125 be evenly distributed, attachment in this manner will cause the back end of the canopy support 125A to tilt downwards, creating a cross sectional surface on which wind may produce drag. The further off center and towards the front end the attachment point is on the canopy assembly 125, the greater the tilt and the larger the cross-sectional area on which wind may act on the canopy assembly 125. However, in instances where wind is not strong enough to create enough drag to greatly affect the downward tilt of the canopy 125B, a user sitting beneath the canopy assembly 125 may have an obstructed view. In one preferred embodiment, a cable 130 may be attached to the front end of the canopy support 125A, which may prevent the back end of the canopy 125B from tilting too far downward when there is not enough wind that the system 100 may use to stabilize the canopy 125B by naturally reducing the cross-sectional area exposed thereto. Alternatively, the cable 130 may be attached to the boom 120 or lever arm 110.
The user may attach the booms 120 to the base 105 during step 1035. The user may then place the base 105, lever arm 110, and booms 120 in a desired assembly position during step 1040. In a preferred embodiment, a user may place the base 105, lever arm 110, and booms 120 in a grounded position 200. Once the base 105, lever arm 110, and booms 120 are in a desired assembly position, the user may attach the canopy supports 125A to the canopy 125B during step 1045 to create the canopy assembly 125. The user may then attach the canopy assembly 125 to the booms 120 during step 1050. The counterweight 115 is to be filled with a substance until a desired weight is obtained during step 1055. In a preferred embodiment, the substance is sand. Once filled, the user may attach the counterweight 115 to the lever arm 110 during step 1060. The user may then place the system 100 in an upright position 600 during step 1065 before heading to terminate step 1070. Some preferred embodiments of the system may include cables 130 designed to prevent the canopy assembly 125 from tilting too far forward or cables 130 and/or counterweights 115 designed to prevent the system 100 from assuming a flipped position 700. These cables 130 and/or additional counterweights 115 may be attached by the user before or after placing the system 100 in an upright position 600.
