BACKGROUND OF THE INVENTION
Field of the Invention
The present disclosure relates generally to a shade canopy tensioning assembly that can maintain a fresh and taught appearance of fabric on shade canopies, including fabric on umbrellas. The assembly may stretch fabric on such canopies as a preventative measure against or remedy for fabric sagging. Also, the present disclosure encompasses a first and second adjustment assembly. When these adjustment assemblies are employed in tandem with a length manipulating bolt and at least one threaded adjustment nut, they can facilitate the adjustment of tension applied to fabric on shade canopies. Additionally, the present disclosure relates generally to providing a sheath that can be attached and support a shade canopy's larger structure. This sheath is capable of enveloping, either partially or wholly, the aforementioned first and second adjustment assemblies, thereby contributing to a visually pleasing aesthetic of shade canopies where at least one shade canopy tensioning assembly is deployed on.
Description of the Related Art
In the field of art relating to large umbrellas and shade canopies commonly used outdoors, after a period of time it can often be observed that the fabric canopy of the umbrella or shade structure begins to sag, and this, in turn, can affect the functionality, longevity, and aesthetic appeal of these products. Sagging refers to the loosening or drooping of the fabric, potentially creating a concave or depressed area on the canopy or umbrella surface. This phenomenon typically arises from environmental conditions, such as prolonged exposure to the sun, rain, fluctuating temperatures etc. but can in certain instances be due to hasty installation, structural and/or design flaws, and material degradation, all of which compromise the tautness and smoothness of the fabric.
Sagging fabric has the potential to significantly impact both the performance and aesthetic appeal of the canopies used on an umbrella or other shade structure. Firstly, it reduces the effectiveness of shade provision, as the sagged areas may allow sunlight to penetrate unevenly or decrease the area/space shaded by fabric. Secondly, sagging fabric tends to accumulate water or other non-gaseous elements of the environment. This fact can lead to water, snow, dirt, or sand pooling in or on fabric. This not only adds extra weight to the structure upon which the canopy rests, but also stretches the fabric further, exacerbating the sagging issue. Moreover, as elements might pool in canopy/umbrella fabrics, living organisms may grow in such pools, causing the fabric to develop an unsightly appearance due to, for example, algae growth upon the fabric. Over time, the constant stress and element accumulation can lead to fabric wear, tear, and eventual failure. Additionally, when canopy/umbrella fabric sags, the intentional aesthetic design envisioned and crafted by the designer(s) becomes obscured or lost, diminishing the aesthetic and functional appearance originally planned.
While a primary cause of fabric sagging may be due to the environment, sagging may also be caused by the structural design of the shade canopy. For instance, non-adjustable ribs or supports limit the ability to tighten or adjust the fabric's tension. In a scenario where ribs are fixed, the fabric may not be stretched adequately during installation, leading to inherent sagging. As ribs may be comprised of a range of materials, they may expand or contract over time due to exposure to the elements, potentially leading to sagging of the canopy. Furthermore, as fabric naturally expands and contracts with temperature fluctuations, the lack of adjustability in the structure prevents compensation for these changes, leading to progressive sagging.
The quality of fabric material also plays a role in sagging. High- or low-quality fabric might be prone to sagging over time dependent on their material construction and design. For example, fabrics not treated for UV resistance may lose their tensile strength and flexibility due to prolonged exposure to sunlight. Similarly, fabrics that are not weather-resistant may absorb moisture, becoming heavier and more susceptible to sagging. Either way, even fabrics that are most resistant to the elements may experience sagging due to the repeated opening and closing of a canopy or umbrella, as this process may cause the fabric to consistently expand and contract.
To address this issue, some solutions have been developed to ensure fabric keeps a fresh, taut appearance by virtue of preventing sagging. However, at the time of this writing, the known solutions still possess challenges and limitations. For instance, one common approach is to ensure proper tensioning and support of the fabric by anchoring the fabric canopy's corners securely and using heavy-duty ropes or straps for horizontal support. Although somewhat effective, this technique not only demands precise, laborious installation and adjustment over time, but also compromises the inherent aesthetic elegance of a canopy or umbrella. Another prevalent approach incorporates elastic and bungee cord systems/assemblies attached to fabric ends, converging at a central point of the canopy or umbrella to retain fabric tautness. Nonetheless, this strategy, while functional, also diminishes the visual appeal of the canopy or umbrella, necessitates frequent assembly and disassembly during opening and closing, and may require multiple individuals for adjustment and tensioning, especially for larger installations.
In light of the challenges outlined, there remains a need for an innovative solution to the sagging fabric problem—one that ensures the fabric can remain taut, fresh, and relatively sag-free without undermining the aesthetic value of the canopy or umbrella. The need demands a solution with a near unnoticeable integration with the original aesthetic, preserving and enhancing the visual allure of the canopy/umbrella installed thereon. Furthermore, this need demands a solution with simplicity and user-friendliness, allowing for effortless adjustments to tighten or loosen canopy/umbrella fabric that can be efficiently executed by a single individual, thereby offering a blend of functionality, beauty, and convenience. Lastly, this need demands a solution that is structurally rigid, such that the overall structure of the canopy or umbrella the solution is installed on is not negatively affected (but may be positively affected) when the solution is used or manipulated.
SUMMARY OF THE INVENTION
The present disclosure provides for a new shade canopy tensioning assembly. While the description is exemplified by referring to an umbrella, the scope of the invention(s) set forth herein should not be so limited, and could be implemented on any kind of shade structure, such as on a vehicle or building.
A shade canopy tensioning assembly, as described herein, is versatile in that it may take various forms. It may incorporate a diverse array of components, which can be combined in different permutations to create multiple distinct versions of the shade canopy tensioning assembly. Also, while one shade canopy tensioning assembly may be used on a shade canopy, a multitude of shade canopy tensioning assemblies may be used on a shade canopy to allow for the fabric of the shade to be stretched (or loosened) in the multiple directions where shade canopy tensioning assemblies are installed on a shade canopy.
That said, the present disclosure relates generally to a shade canopy tensioning assembly comprising a first adjustment assembly, at least one threaded adjustment nut, a second adjustment assembly, at least one length manipulating bolt, and sheath. A shade canopies' fabric may be attached to the first adjustment assembly and affixed to another point. A length manipulating bolt is run through the first adjustment assembly, at least one threaded adjustment nut, a second adjustment assembly, and a sheath. As this length manipulating bolt is rotated via external means (such as through a tool), the first adjustment assembly selectively slides in or out of the sheath, tightening or loosening the canopy fabric. The sheath may be attached to, or may also comprise, a rigid and fixed (relative to the canopy) support member.
The first adjustment assembly may have at least one canopy attachment point where a canopy can attach to the attachment point. The first adjustment assembly may also be made up of an adjustment member, a sleeve member, and a first rotation lock. Each the adjustment member, sleeve member, and first rotation lock may be in removable connection to one another.
The adjustment member may have the canopy attachment point thereon/formed therein and may also have at least one aperture formed therein. The at least one aperture may be configured and dimensioned to receive at least one length manipulating bolt such that a length manipulating bolt may enter the adjustment member (and enter or pass through the first adjustment assemblies' various components) in a horizontal plane of the adjustment member (and horizontal plane of the first adjustment assembly). Additionally, the adjustment member may have a first sleeve member insert, wherein the first sleeve member insert is configured and dimensioned to be inserted and secured to the aforementioned sleeve member.
As such, the sleeve member resembles a tube with openings at either side, a first opening and a second opening. Therefore, the first sleeve member insert may be inserted into the sleeve member at a first opening. To secure the first sleeve member insert to the sleeve member, the first sleeve member insert may have at least one screw hole dimensioned to align with at least one first screw hole formed on the sleeve member. This dimensioning may allow for at least one screw to traverse each of the sleeve member's first screw hole and the first sleeve member insert's screw hole, thereby securing the first sleeve member insert to the sleeve member.
On the second opening of the sleeve member, the aforementioned first rotation lock may be inserted. The first rotation lock may have at least one primary arcuate tab formed thereon, and a second sleeve member insert. The second sleeve member insert may facilitate the insertion and securing of the first rotation lock into the sleeve member. To this end, the second sleeve member insert may be inserted into the sleeve member at a second opening of the sleeve member. To secure the second sleeve member insert to the sleeve member, the second sleeve member insert may have at least one screw hole dimensioned to align with at least one second screw hole formed on the sleeve member. This dimensioning may allow for at least one screw to traverse each of the sleeve member's second screw hole and the second sleeve member insert's screw hole, thereby securing the second sleeve member insert to the sleeve member.
As the first rotation lock may have at least one primary arcuate tab formed thereon, the at least one primary arcuate tab may be in sliding engagement with at least one groove of the aforementioned sheath. For context, the primary arcuate tab may be formed on an exterior of the first rotation lock that has a first dimension. The primary arcuate tab may thus be engaged with the groove of the sheath, the groove being formed on an interior of the sheath of a second dimension, greater than the first dimension. Due to the primary arcuate tab's engagement with the groove, the configuration may prevent rotation of the first rotation lock within the sheath while simultaneously permitting translation of the first rotation lock (and thereby the first adjustment assembly) within the sheath. To this end, the sheath may at least partially envelope the first adjustment assembly. The arcuate tab may be alternatively described as a spline serving to transmit torque from the first adjustment assembly to the second adjustment assembly.
As the first adjustment assembly comprises the adjustment member, sleeve member, and first rotation lock, the sheath may envelope the first rotation lock and at least part of the sleeve member. Impliedly, this may allow the dimensioning of the first rotation lock and the sleeve member to fit within the sheath. Also, impliedly, this may allow the adjustment member to remain unenveloped by the sheath (or simply, exposed to the elements) and may allow the adjustment member to have a dimensioning larger than what may fit within the sheath. As will be described in subsequent detail, the first adjust member may thus translate in or out of the sheath, the sleeve member becoming more or less enveloped by the sheath as the first adjustment assembly is slid in or out of the sheath.
To prevent the first adjustment assembly from sliding completely out of the sheath, the sheath may have a retention ring installed therein. The retention ring may be of a third dimension, smaller than the aforementioned second dimension, but greater than the first dimension. In effect, such dimensioning may allow for the first rotation lock to be retained within the sheath by the retaining ring, preventing the first rotation lock's exit from the sheath.
As per the sheath, the sheath may be a tubular structure with any cross-sectional shape (a circle, square, triangle). The sheath may be of a dimension and length that allows the at least one length manipulating bolt to be inserted into the sheath and extend the full length of the sheath. Further, the sheath may comprise a hinge or movement assembly at a distal end opposite to the distal end the first adjustment assembly may be located on/in the sheath (as may be inferred from the Figures). The hinge or movement assembly may be an assembly that is at least partially enveloped by the sheath, or not enveloped at all, but structured to allow the sheath to move or rotate about a hub, runner hub, lift, slider, leg, pole, wall mount, or other structure that may support a shade canopy. Also, the sheath may comprise a structural support for a canopy rib, drive head assembly, or idler head assembly, roller, or arm support. The structural support may be an assembly that is at least partially enveloped by the sheath, or not enveloped at all, and may be located at any distance along a length of a sheath. The structural support may allow a canopy rib (or other similar structure) to connect to the sheath and may otherwise act as a device to connect a structure that supports the shade canopy.
As the assembly may have at least one length manipulating bolt, the length manipulating bolt may traverse, at least a partial length through the first adjustment assembly, fully through at least one adjustment nut (which may be a lock nut, self-locking nut, or other form of nut that resists loosening under vibrations and torque), and at least partially through the second adjustment assembly. Inherently, the length manipulating bolt may have threading and a bolt head. The length manipulating bolt may also be of stainless-steel composition.
The length manipulating bolt may be dimensioned such that it can be inserted into the aforementioned aperture of the adjustment member on the first adjustment assembly and an aperture of the second adjustment assembly (as will be subsequently described). In such an instance, the length manipulating bolt's bolt head may not be able to traverse the aperture of the adjustment member such that the shank and threads of the bolt are inserted through the aperture of the adjustment member, but the bolt head is not. Additionally, the bolt head may have a commonly known drive/recess such as a flat head recess, Phillips head recess, or hex (Allen) key recess. Also, the bolt head may have a head of a dimension that is able to be rotated by a socket, bit, or wrench.
The length manipulating bolt may be configured and dimensioned to selectively distance the first adjustment assembly and the second adjustment assembly by rotation of the at least one length manipulating bolt within the at least one threaded adjustment nut. As such, and as will be described in subsequent detail and as may be apparent from the Figures, the length manipulating bolt may allow for at least part of the first adjustment assembly to translate in or out of the sheath, through the rotation of the at least one length manipulating bolt. One means by which the length manipulating bolt accomplishes this objective is that the at least one threaded nut is coupled to the first adjustment assembly in non-rotating engagement (preventing the threaded nut and the first adjustment assembly from rotating about one another), or otherwise disposed in a non-rotating engagement such that the at least one threaded nut does not rotate when the length manipulating bolt is rotating within the at least one threaded nut. Therefore, as the at least one length manipulating bolt is rotated about the at least one adjustment nut, the length manipulating bolt either pushes or pulls the first adjustment assembly closer to or further from the second adjustment assembly (also allowing at least part of the first adjustment assembly to slide in or out of the sheath). As a result, the length manipulating bolt may configured and dimensioned to permit translation of the at least one threaded nut and a first adjustment assembly within the sheath.
As may now be apparent, should an edge of a canopy be attached to the first adjustment assembly at the canopy attachment point, the remainder of the canopy extending in a direction away from the first adjustment member and fixed at a point in such a direction, as the first adjustment member is slid out from the sheath via rotation of the length manipulating bolt, the canopy is tightened. Such tightening allows for the canopy to maintain a taut appearance.
As per the second adjustment assembly, the second adjustment assembly may be completely enveloped by the sheath. Moreover, the second adjustment assembly may also comprise an aperture and a second rotation lock. The at least one aperture of the second adjustment assembly may be configured and dimensioned to receive the at least one length manipulating bolt about a horizontal plane of the second adjustment assembly.
As the second adjustment assembly is completely enveloped by the sheath, impliedly, this may allow the dimensioning of the second rotation lock to fit within the sheath. To secure the second rotation lock (and the second adjustment assembly) to the sheath, the second rotation lock may have at least one screw hole dimensioned to align with at least one screw hole formed on the sheath. This dimensioning may allow for at least one screw to traverse each of the second rotation lock's screw hole and the sheath's screw hole, thereby securing the second rotation lock (and second adjustment assembly) to the sheath.
Lastly, the second rotation lock may have at least one secondary arcuate tab formed thereon. The at least one secondary arcuate tab may be in engagement with at least one groove of the aforementioned sheath. For context, the secondary arcuate tab may be formed on the exterior of the second rotation lock that has a first dimension. The secondary arcuate tab may thus be engaged with the groove of the sheath, the groove being formed on the interior of the sheath of a second dimension, greater than the first dimension. Due to the secondary arcuate tab's engagement with the groove, the secondary arcuate tab may prevent rotation of the secondary rotation lock within the sheath.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Turning now descriptively to the figures, FIG. 1 illustrates a perspective view of a portion of a shade canopy tensioning assembly 5. A sheath 30, encompassing a first adjustment assembly (and various elements thereof) can be seen. The sheath 30, as will be subsequently described, may envelop at least part of the first adjustment assembly 10 and may comprise a retention ring 32 and at least one screw hole 31 (as will be subsequently described). For example, while the first adjustment assembly 10 may have various elements (such as an adjustment member 11, at least one canopy attachment point 12, at least one aperture 13, first sleeve member insert 14, sleeve member, at least one first sleeve member screw hole 16, at least one second sleeve member screw hole 17, a first rotation lock 18, a second sleeve member insert 18′, and at least one primary arcuate tab 19), only some of the elements, namely, element identifiers 11, 12, 13, 15, and 16 are visible, which indicates other element identifiers may be enveloped by the sheath 30. That said, the first adjustment assembly 10 may translate in or out of the sheath 30 (exposing more or less of the first adjustment assembly 10 outside of the sheath 30) via rotation of at least one length manipulating bolt 40 (as will be described in more detail). This sliding allows for fabric of a shade canopy (which might be affixed to the first adjustment assembly 10 at the adjustment member 11) to become more or less taut (where the mechanics of which and components facilitating such movement will be described in more detail).
Fabric of a shade canopy may be removably attached to the shade canopy tensioning assembly 5 via the canopy attachment point 12. Fabric of a shade canopy may be a number of different materials that may be used to provide shade or protection from the elements (such as rain, water or dust). As such, fabric of a shade canopy may be, and is not limited to being, polyester, canvas, coated canvas, acrylic, olefin, vinyl, fabric made under the trademark Sunbrella® or fabrics similar thereto, polyvinyl chloride (as a coating on fabric or fabric itself), nylon, and/or solution-dyed fabrics. That said, the canopy attachment point 12 may be a range of different solutions that can removably connect to the fabric. For example, the canopy attachment point 12 may be a grommet (that may receive an eyelet affixed to the fabric), a button (that may receive a snap affixed to the fabric), a Velcro strip (that corresponds to a Velcro strip of the fabric), a magnetic fastener (that may magnetically attract a magnet on the fabric), or a structure (that can have the fabric tied to or hooked thereon). To this end, the fabric may pertain to a shade canopy, and the shade canopy may be, and is not limited to being an umbrella, pop-up canopy, awning, pergola (with fabric providing shade thereto), cabana (with fabric providing shade thereto), gazebo (with fabric providing shade thereto), marquee, tent, or carport. As such, and as may be apparent, the present disclosure is contemplated as being usable on variety of shade canopies.
With reference now to FIG. 2, for purposes of further understanding the present disclosure, a portion of a shade canopy tensioning assembly 5 is shown in perspective view without a sheath 30. As such, FIG. 2 represents what may be at least partially enveloped by a sheath 30, namely, the first adjustment assembly 10 (which is at least partially enveloped by the sheath 30) and a second adjustment assembly 20 (which may be fully enveloped by a sheath 30). As such, in addition to the first adjustment assembly's 10 elements as depicted in FIG. 1, the first adjustment assembly's 10 second sleeve member screw hole 7, first rotation lock 18, and primary arcuate tab 19 may be seen. In addition, the second adjustment assembly 20, having a second rotation lock, at least one screw hole 26, and a secondary arcuate tab 28 can also be seen. Notably, the present disclosure contemplates at least one second adjustment assembly 20 and a shade canopy tensioning assembly may comprise more than one second adjustment assembly 20. As may be inferred with reference to FIG. 2, at least one length manipulating bolt 40 may traverse the length of the first adjustment assembly 10 and second adjustment assembly 20 (in a horizontal plane as will be subsequently described and depicted). With brief reference to FIG. 3 and FIG. 8, it may be noted that the at least one length manipulating bolt 40 may traverse through at least one threaded adjustment nut 50, and may traverse the entire length of a sheath. With reference to FIG. 2, as may be seen, the at least one length manipulating bolt 40 may be inserted into and through the first adjustment assembly 10 at an aperture 13 of the first adjustment assembly 10. The aperture 13 may be configured and dimensioned to house the at least one length manipulating bolt's 40 head.
With reference now to FIG. 3 for purposes of further understanding to present disclosure, FIG. 3 is an exploded perspective view of portions of a shade canopy tensioning assembly. Specifically, FIG. 3 depicts how elements such as the first adjustment assembly 10, threaded adjustment nut 50, second adjustment assembly 20, length manipulating bolt 40, and sheath 30 may align with one another. Moreover, FIG. 3 depicts how each element aligns with themselves. For example, with reference to the first adjustment assembly 10, the first sleeve member insert 14 can be viewed, as well as the adjustment member 11 which may be attached/affixed thereto or formed thereon. It can be noted that the first sleeve member insert 14 may be inserted into the sleeve member 15. Before insertion, a retention ring 32 may be inserted over the first sleeve member insert 14 (the purpose and structure of which will be subsequently described). Thereafter, it can be noted that the first sleeve member insert 14 may be secured to the sleeve member 15 by virtue of a screw 60. As may be apparent from the Figure, a screw 60 may traverse the sleeve member 15 and the first sleeve member insert 14 (at the corresponding and aligning first sleeve member insert screw hole 14′ and at least one first sleeve member screw hole 16), thereby securing the first sleeve member insert 14 to the sleeve member 15. As may be apparent, more than one screw 60 may traverse the sleeve member 15 and the first sleeve member insert 14 to secure the first sleeve member insert 14 to the sleeve member 15.
With continued reference to the first adjustment assembly, it may also be noted that the second sleeve member insert 18′ may be inserted into the sleeve member 15. Thereafter, it can be noted that the second sleeve member insert 18′ (with a first rotation lock 18 attached thereon or formed thereon) may be secured to the sleeve member 15 by virtue of a screw 60. As may be apparent from the Figure, a screw 60 may traverse the sleeve member 15 and the second sleeve member insert 18′ (at the corresponding and aligning second sleeve member insert screw hole 18″ and at least one second sleeve member screw hole 17), thereby securing the second sleeve member insert 18′ to the sleeve member 15. As may be apparent, more than one screw 60 may traverse the sleeve member 15 and the second sleeve member insert 18′ to secure the second sleeve member insert 18′ to the sleeve member 15.
With continued reference to the first adjustment assembly 10, and assuming the above elements are inserted and secured as mentioned in the above, at least one length manipulating bolt 40 may be inserted into the first adjustment assembly 10 (as depicted). As not depicted in FIG. 3, the at least one length manipulating bolt 40 may be inserted and secured to the at least one threaded adjustment nut 50 (which will be described in more detail). As will also be described in more detail, as the at least one length manipulating bolt 40 may rotate, the length manipulating bolt 40 may rotate within the first adjustment assembly 10, and within the threaded adjustment nut 50. As the at least threaded adjustment nut 50 may be fixed in a non-rotational state and affixed to the first adjustment assembly (as will be subsequently described), the rotation of at least one length manipulating bolt 40 may cause the first adjustment assembly 10 to traverse a distance (left or right about a horizontal plane) along the at least one length manipulating bolt 40. As will be subsequently described, this movement allows at least part of the first adjustment assembly 10 to slide in or out of the sheath 30.
With continued reference to FIG. 3, the second adjustment assembly 20 can be seen, wherein a second rotation lock 21 is formed thereon, and a screw hole 26 with a secondary arcuate tab 28 being formed on the second rotation lock 28. Reference to the sheath 30 may also be made. As such, the second adjustment assembly 20 may be inserted into the sheath 30. Notably, the sheath 30 may have at least one groove 35 that corresponds to at least one secondary arcuate tab 28, allowing the second adjustment assembly 20 to be inserted at a specific orientation within the sheath 30. Notably, this orientation may allow for the screw hole 26 to eventually align with the screw hole 31 of the sheath 30 upon the second adjustment assembly 20 reaching a specific length within the sheath 30. As may be apparent, the corresponding secondary arcuate tab 28 and groove 35 allows the secondary adjustment assembly 20 to be inserted in a non-rotating fashion in the sheath 30, meaning that the secondary adjustment assembly 20 is incapable of rotating within the sheath by virtue of the secondary arcuate tab 28's formation on the second rotation lock 21. As may also be apparent, when aligned, the screw hole of the sheath 31 and the screw hole 26 of the second rotation lock 21 (wherein the screw hole 26 may alternatively be located on the second adjustment assembly 20), may allow a screw 60 to traverse therethrough, securing the second adjustment assembly 20 in place within the sheath 30 such that the second adjustment assembly 10 may not slide or move about a horizontal plane of the sheath 30.
With continued reference to FIG. 3 and considering the above, the first adjustment assembly 10, may also then be inserted into the sheath 30 (along with the at least one threaded adjustment nut 50, which may be affixed to the first adjustment assembly 10, and at least a portion of the at least one length manipulating bolt 40). The result thereof may be considered as depicted in FIG. 1. As may not be apparent, but as may be part of the present disclosure, the at least one length manipulating bolt 40, may traverse through the second adjustment assembly 20 as the second adjustment assembly 20 may have an aperture that allows the length manipulating bolt 40 to penetrate therethrough. Notably, the first rotation lock 18, with its at least one primary arcuate tab may also have been inserted into a corresponding at least one groove 35 of the at least one sheath 30. Such an insertion and corresponding elements may allow for the first adjustment assembly 10 (when conjoined as described above) to remain in a fixed non-rotational orientation within the sheath 30. However, the first adjustment assembly 10 may still be able to translate (slide) about the sheath 30 via rotation of the at least one threaded adjustment nut 50 (as will be subsequently described), and be guided, at least in part by the at least one groove 35 via the orientation of the at least one primary arcuate tab 19 in the at least one groove 35.
With continued reference to FIG. 3 and in light of the above, as may now be apparent, the exterior dimensioning of the first and second rotation locks 18/21 are smaller than the interior dimensioning of the sheath 30, allowing the first and second rotation locks 18/21 to be inserted into the sheath 30. That said, and as previously described, the retention ring 32 may have been placed over the first sleeve member insert 14. The dimensioning of the retention ring 32 may allow the retention ring 32 to freely slide over the first sleeve member insert 14, sleeve member 15, and second sleeve member insert 18′. However, as the sleeve member 15 may have an adjustment member 11 and a first rotation lock 18 on either end, the dimensioning of the retention ring 32 could be smaller than the adjustment member 11 and rotation lock 18 such that, when the retention ring 32 is placed over the first sleeve member insert 14, sleeve member 15, and second sleeve member insert 18′, it may only slide between the adjustment member 11 and rotation lock 18. Also, as the first adjustment assembly 10 (with retention ring 32 thereon) is inserted into the sheath 30, the retention ring 32 may have a structure designed to lock into the sheath 30. While non-limiting in depiction and structure for the purpose of this disclosure, FIG. 3 depicts extrusions of the retention ring 32 that may correspond to intrusions on the sheath 30 that allow the retention ring 32 to lock into place once inserted into the sheath 30. Therefore, the retention ring may allow the adjustment member 11 to be pushed up against the sheath 30 (and retention ring 32) when the first adjustment assembly 10 is slid fully into the sheath 30. However, when the first adjustment assembly is slid out of the sheath 30, once the first rotation lock 18 reaches the exit of the sheath 30 (where the retention ring 32 is located on the Figures), the first rotation lock 18 presses up against the retention ring 32, preventing the first adjustment assembly 10 from exiting the sheath 30. As such, the first adjustment assembly 10 is able to slide in and out of the sheath 30 (via rotation of the at least one length manipulating bolt 40), but is only able to slide in and out of the sheath 30 for the distance between the adjustment member 11 and the first rotation lock 18. This sliding action, when fabric of a canopy shade is affixed to the canopy attachment point 12, allows the fabric to be come more or less taut depending on the distance the first adjustment assembly 10 is slid out of the sheath. Brief reference to FIG. 10 may be had to determine where the shade canopy tensioning assembly 5 may be installed thereon and, considering the above, how the shade canopy tensioning assembly 5 may keep the fabric of the shade canopy more or less taut. Critically, this sliding action allows for a simplistic and clean line design wherein the first adjustment assembly 10 looks like a natural extension of a sheath 30. This design also provides for the appearance of consistency, continuity, precision and alignment. In turn, this design may enhance the overall look of a shade canopy that where fabric tautness is desired. Further, this design may minimally intrude on the intended design of the canopy, providing functional elegance. Lastly, the materials and finish of the first adjustment assembly 10 and sheath 30 may be similar, if not identical, such that the first adjustment assembly 10 looks like a natural continuation of the sheath 30, if noticed at all, as the design may provide a near unnoticeable seamlessness to a canopy design where the shade canopy tensioning assembly 5 is installed.
FIG. 4 depicts a top view of portions of a shade canopy tensioning assembly 5 without depicting the shade canopy tensioning assembly's sheath 30. As previously mentioned and as is now depicted in FIG. 4, the length manipulating bolt 40 may traverse, at least partially through the first adjustment assembly 10, through the threaded adjustment nut 50, and through the second adjustment assembly 20 (wherein the length manipulating bolt 40 may traverse only partially through the second adjustment assembly 20, as is not depicted). Also, as not depicted, the shade canopy tensioning assembly 5, may have more than one second adjustment assembly 20, and a length manipulating bolt 40 may travel fully though one second adjustment assembly 20, and at least partially through other second adjustment assemblies 20. That said, as previously mentioned, the at least one threaded adjustment nut 50 may be affixed to the first adjustment assembly 10. As such, the at least one threaded adjustment nut 50 may be affixed by virtue of; the first adjustment assembly 10 having a cavity/slot at least part of the threaded adjustment nut 50 may fit into, the threaded adjustment nut 50 being welded or adhered to the first adjustment assembly 10, or the at least one threaded adjustment nut 50 being set, with screws, into the first adjustment assembly 10. Therefore, as the at least one length manipulating bolt 40 is introduced into the first adjustment assembly 10 and the at least one threaded adjustment nut 50, as the length manipulating bolt 40 is rotated within the threaded adjustment nut 50, the first adjustment assembly 10 (by virtue of connection/affixation to the threaded adjustment nut 50) will move either back or forth along the length manipulating bolt 40 dependent on the direction of rotation the length manipulating bolt 40 is spun.
FIG. 5 is a side sectional view of portions of a shade canopy tensioning assembly as if it were cut in half along a vertical plane passing therethrough (as depicted in FIG. 6 as V), without depicting the shade canopy tensioning assembly's sheath 30. As described above, the first sleeve member insert 14 and the second sleeve member insert 18′ may be inserted into the sleeve member and affixed thereto using screws 60. As may also be apparent, the dimensioning of the adjustment member 11 and first rotational lock 18 can be viewed as having a greater dimensioning (along the vertical plane V) than the sleeve member 15 (which allows for the retention ring's 32 retention of the first adjustment assembly 10 in the sheath 30 as previously described. Also, while not necessary to connect fabric of a shade canopy to the first adjustment assembly 10, the canopy attachment point 12 is depicted as a channel that may receive fabric or a pin attached to fabric such that the fabric is attached to the first adjustment assembly 10, via the adjustment member 11 and the canopy attachment point 12. While not depicted, the canopy attachment point may be located elsewhere along the first adjustment assembly 10, such as on the sleeve member 15, or as the aperture 13 (which, in addition to serving as an entry point for a length manipulating bolt 40, can also serve as the canopy attachment point 12).
FIG. 6 is a top view of a portion of shade canopy tensioning assembly, depicting how a portion of the shade canopy tensioning assembly might move, and a vertical plane of the shade canopy tensioning assembly 5. The vertical plane V is depicted, which runs into the page. Notably, the movement of the first adjustment assembly 10 (which is partially depicted due to its insertion and partial envelopment by the sheath 30) is depicted as L, wherein the movement L represents the ability of the first adjustment assembly 10 to slide in or out of the sheath 30.
FIG. 7 is a side sectional view of a portion of shade canopy tensioning assembly, depicting how a portion of the shade canopy tensioning assembly 5 might move about a horizontal plane of the shade canopy tensioning assembly. The horizontal plane H is depicted, which runs into the page. Notably, the movement of the first adjustment assembly 10 is depicted as L, wherein the movement L represents the ability of the first adjustment assembly 10 to slide, along the horizontal plane H, in or out of the sheath 30. As may also be apparent, the dimensioning of the first adjustment assembly 10 and the sheath 30 can be viewed, the dimensioning of the first adjustment assembly 10 being smaller in dimension, (along the vertical plane V) than the sheath 30 (which allows for the first adjustment assembly 10 to at least slide into the sheath 30 as previously described. Also, as described above, the second adjustment assembly 20 may be inserted into the sheath 30, and affixed to the sheath 30 by virtue of a screw 60 traversing through the sheath's screw hole 31 and the screw hole 26 of the second adjustment assembly 20, which may, but need not be located on the second rotation lock 21.
FIG. 8 is a perspective view of a shade canopy tensioning assembly, wherein the perspective view of FIG. 1 is denoted thereon. Also visible is a hinge or movement assembly 34. However, the hinge or movement assembly 34 need not be present on the shade canopy tensioning assembly 5, and instead may have simply an attachment mechanism (such that the sheath 30 may be affixed to another structure). That said, should a hinge or movement assembly 34 be present, the hinge may allow the sheath 30 to rotate or move about another structure, as previously described. Also, visible is a structural support 33, which also need not be present on the shade canopy tensioning assembly 5. As previously described, the structural support 33 may be an assembly that is at least partially enveloped by the sheath 30, or not enveloped at all, and may be located at any distance along a length of a sheath 30. A shade canopy tensioning assembly may have more than one, or no structural supports. The structural support 33 may allow a canopy rib (or other similar structure) to connect to the sheath 30 and may otherwise act as a device to connect a structure that supports the shade canopy.
FIG. 9 is an exploded, perspective view of a shade canopy tensioning assembly, wherein the exploded, perspective view of FIG. 3 is denoted thereon. Visible on FIG. 9 is how more than one secondary adjustment assembly 20 may be present on a shade canopy tensioning assembly 5, wherein more than one secondary adjustment assemblies 20 may have a length manipulating bolt 40 pass therethrough, the assemblies 20 allowing for the bolt 40 to be guided in a certain orientation as it traverses through the multiple elements which may be, at least partially, enveloped by the sheath 30. Also visible is how the hinge or movement assembly 34 is instead depicted as an attachment mechanism (which may attach to another structure so as to support the shade canopy tensioning assembly).
FIG. 10 is a perspective front view of a shade canopy, denoting where multiple shade canopy tensioning assemblies may be installed on a shade canopy and denoting what multiple shade canopy tensioning assemblies 5 may appear as when installed on the shade canopy. As previously described, the shade canopy tensioning assembly 5 may, from an aesthetic point of view, cleanly integrate into a shade canopy and have the shade canopy appear as if the shade canopy tensioning assemblies 5 are not noticeable on the canopy.
Without reference to the figures, it may be noted that the first rotation lock 18 (and at least one primary arcuate tab 19 formed thereon) and the at least one second rotation lock 21 (and at least one secondary arcuate tab 28 formed thereon) may be of polyvinyl chloride, metal, or plastic construction. The at least one threaded adjustment nut 50 may be composed of stainless steel. Also, the at least one threaded adjustment nut 50 may be of a lock nut design. The screw 60 or various screws 60 as depicted in the Figures may be composed of stainless steel and have a commonly recognized recess, such as a Phillips head or flat head recess. Also, the screw 60 or various screw 60 as depicted in the Figures may have a flat or pointed tip. The at least one length manipulating bolt 40 may be composed of stainless steel. Also, the length manipulating bolt's 40 head may be configured and dimensioned to fit into the aperture such that the length manipulating bolt's 40 head is not visible from a side view of the first adjustment assembly. Also, the length manipulating bolt's 40 head may have a commonly recognized recess, such as a hex key/Allen key, or be rotatable through the use of a socket and wrench around the exterior of the bolt's 40 head.
FIG. 11 is a perspective view of an alternative form of a shade canopy tensioning assembly when compared with the aforementioned shade canopy tensioning assembly 5, made up of distinct views (FIGS. 11A, B, C, and D) to understand the alternative form of the shade canopy tensioning assembly depicted therein.
FIG. 11A depicts an exploded view of a sheath 30 (which may comprise the same components and functionalities as the aforementioned sheath 30), having a retention ring 32 (which may comprise the same components and functionalities as the aforementioned retention ring 32), and at least one groove 35 (which may comprise the same components and functionalities as the aforementioned at least one groove 35). Moreover, the sheath 30 may have at least one screw hole 31, which may be used in conjunction with a screw 60 so as to lock at least one second adjustment assembly 20 in place (in a similar fashion as was previously mentioned).
FIG. 11B depicts an exploded view of a first adjustment assembly 10, a second adjustment assembly 20, at least one threaded adjustment nut 50, and at least one length manipulating bolt 40. As may be inferred, elements remain the same when compared to the aforementioned shade canopy tensioning assembly 5, however, per FIG. 11B, the shade canopy tensioning assembly depicted therein has a different orientation/configuration of such elements. Notably, the at least one threaded adjustment nut 50 is oriented as being placed in the aperture 13 of the adjustment member 11 of the first adjustment assembly 10 (where the aperture 13 may not allow the threaded adjustment nut 50 to rotate within the aperture 13). Therefore, it may be inferred that the shade canopy tensioning assembly as depicted in FIG. 11 is of a different orientation/configuration of the elements, notably, the at least one threaded adjustment nut 50 being placed on or in the adjustment member 11. Such an alignment/configuration still provides for the first adjustment assembly 10 to slide in or out of the sheath 30 (as previously described via the same means as previously described).
FIG. 11D is a perspective view of the shade canopy tensioning assembly wherein the sheath 30 is see-through such that the elements as described in FIG. 11A and FIG. 11B may be seen when they are installed, at least partially within the sheath 30.
FIG. 11C is a perspective view of the shade canopy tensioning assembly wherein the sheath can be viewed as housing the first adjustment assembly 10, wherein the first adjustment assembly 10 may be slid in or out of the sheath 30 (in a movement, depicted as L) when a rotational force R, applied by a tool T, is applied to the at least one length manipulating bolt 40 installed in the first adjustment assembly 10.
FIG. 12 is a perspective view of an alternative form of a shade canopy tensioning assembly when compared with the aforementioned shade canopy tensioning assemblies, made up of distinct views (FIGS. 12A, B, C, and D) to understand the alternative form of the shade canopy tensioning assembly depicted therein.
FIG. 12A depicts an exploded view of a sheath 30 (which may comprise the same components and functionalities as the aforementioned sheath 30), having a retention ring 32 (which may comprise the same components and functionalities as the aforementioned retention ring 32 but instead of having a first rotation lock 18 press up against, it, the retention ring 32 has a screw 60, which is inserted into a second sleeve member screw hole 17 press up against it to retain the first adjustment assembly 10 in the sheath 30, allowing it to slide therein), and at least one groove 35 (which may comprise the same components and functionalities as the aforementioned at least one groove 35). Moreover, the sheath 30 may have at least one screw hole 31, which may be used in conjunction with a screw 60 so as to lock a second sleeve member insert 18′ in place (which is distinct from the aforementioned disclosure above, but modified such that the second sleeve member insert screw hole 18″ may allow the screw 60 to lock the second sleeve member insert 18′ in place within the sheath 30).
FIG. 12B depicts some of the same aforementioned elements, but includes new elements and a distinct orientation than the aforementioned shade canopy tensioning assembly. Firstly, a claim C is present that may clamp onto the first sleeve member insert 14 and receive a screw 60 through the first sleeve member screw holes 16, keeping the first sleeve member insert 14 in place within the sleeve member 15. Next, the sleeve chamber 70, which can be combined with the at least one threaded adjustment nut 50 is present. The sleeve chamber 70 may be of dimensioning that allows it to fit within the sleeve member 15. Also, the sleeve chamber may comprise a screw hole 71, such that the screw hole 71 may be aligned with the second sleeve member screw hole 17, fixing the sleeve chamber 70 in place. The sleeve chamber 70 may house or be otherwise fixed to the threaded adjustment nut 50, allowing the threaded adjustment nut 50 to rotate about the length manipulating bolt 40 As such, as the first adjustment assembly 10, comprising the first sleeve member insert 14, in place with the sleeve member 15, and the sleeve chamber 70, in place within the sleeve member 15 and housing the threaded adjustment nut 50, can be rotated about the length manipulating bolt 40. This rotation allows for the first adjustment assembly to slide in or out of the sheath 30, providing for the same uses and benefits as previously mentioned.
With continued reference to FIG. 12B, notably, the second sleeve member insert 18′ is not inserted into the sleeve member 15. However, the second sleeve member insert 18′ acts essentially as a second adjustment assembly 20 (as described above, in that it can be locked into place within a sheath 30). Also, notably, the orientation of the at least one length manipulating bolt 40 is flipped in that the bolt's 40 head is orientated away from the first adjustment member 10, which implies the length manipulating bolt 40 is held in place where the first adjustment member 10 (through the at least one threaded adjustment nut 50) rotate about the at least one length manipulating bolt. Also, the screw 60, which may be inserted into the second sleeve member screw hole 17 and the sleeve chamber screw hole 71 may be of a length such that its head will push up against the retention ring 32, retaining the first adjustment assembly 10.
FIG. 12D is a perspective view of the shade canopy tensioning assembly wherein the sheath 30 is see-through such that the elements as described in FIG. 12A and FIG. 12B may be seen when they are installed, at least partially within in the sheath 30.
FIG. 12C is a perspective view of the shade canopy tensioning assembly wherein the sheath 30 can be viewed as housing the first adjustment assembly 10, wherein the first adjustment assembly 10 may have a rotational force R, applied by a tool T, hand, or outside force, applied to the first adjustment assembly 10 so as to allow the first adjustment assembly 10 to slide in or out of the sheath in a movement, depicted as L.
FIG. 13 is a perspective view of an alternative form of a shade canopy tensioning assembly when compared with the aforementioned shade canopy tensioning assemblies, made up of distinct views (FIGS. 13A, B, C, and D) to understand the alternative form of the shade canopy tensioning assembly depicted therein. However, FIG. 13 is an extension of FIG. 12, in that the length manipulating bolt 40, nor the second sleeve member insert 18 are imaged in FIG. 13 (but may nevertheless be present in such a shade canopy tensioning assembly). Also, in FIG. 13B, the sleeve chamber 70 has a threaded adjustment nut therein, or similar structure, connected to a bevel gear or rack and pinion structure. The bevel gear or rack and pinion structure is able to have a force applied thereto R (through a tool T), as imaged in FIG. 13C, allowing the first adjustment assembly 10 to slide in or out of the sheath 30 in a movement as depicted as L.
FIG. 13A depicts an exploded view of a sheath 30 (which may comprise the same components and functionalities as the aforementioned sheath 30), having a retention ring 32 (which may comprise the same components and functionalities as the aforementioned retention ring 32 but instead of having a first rotation lock 18 press up against, it, the retention ring 32 has a screw 60, which is inserted into a second sleeve member screw hole 17 press up against it to retain the first adjustment assembly 10 in the sheath 30, allowing it to slide therein), and at least one groove 35 (which may comprise the same components and functionalities as the aforementioned at least one groove 35). As not depicted, the sheath 30 may have at least one screw hole 31, which may be used in conjunction with a screw 60 so as to lock a second sleeve member insert 18′ in place (which is distinct from the aforementioned disclosure above, but modified such that the second sleeve member insert screw hole 18″ may allow the screw 60 to lock the second sleeve member insert 18′ in place within the sheath 30).
FIG. 13D is a perspective view of the shade canopy tensioning assembly wherein the sheath 30 is see-through such that the elements as described in FIG. 13A and FIG. 13B may be seen when they are installed, at least partially within in the sheath 30.
It is intended that all matters in the foregoing disclosure and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
