Smart Summary: A fixed shade sail is made of a large piece of tarpaulin with a top and bottom side. It has several anchoring points around the edges to hold it in place. Main tie-rods are used to pull the tarpaulin tight between supports that are secured to the ground. Additionally, there is a flexible secondary tie-rod attached to the bottom side of the tarpaulin, which can be adjusted to provide extra support. This secondary tie-rod helps keep the tarpaulin flat and stable by pulling it down in the middle. 🚀 TL;DR
A fixed shade sail has a tarpaulin on which a lower face and an upper face are identified, a plurality of anchoring bodies connected to the tarpaulin along a peripheral edge of the tarpaulin, and a plurality of main tie-rods connectable to the anchoring bodies for tensioning, in use, the tarpaulin between a plurality of supports directly or indirectly anchored to ground. The fixed shade sail has at least one secondary tie-rod of flexible type arranged at the lower face and directly or indirectly anchorable to the tarpaulin close to or at two ends of the secondary tie-rod. A length of the secondary tie-rod is adjustable through tensioning devices so that the secondary tie-rod is taut between two different portions of the tarpaulin until the secondary tie-rod adheres to the lower face, passes at least close to a central area of the tarpaulin and acts as support for the tarpaulin.

This application claims priority to and benefit of Italian Patent Application No. 102024000016693 filed Jul. 18, 2024, the contents of which are incorporated by reference in their entirety.
The present invention relates to a fixed shade sail.
As shown in FIGS. 1 and 2, a fixed shade sail V (also referred to as a static sail in contrast to a retractable sail) comprises a tarpaulin T which, in the mounted condition, is supported in place by means of anchoring tie-rods R.
In more detail, the tarpaulin, usually of polygonal shape, is anchored to support poles P and/or building walls by means of the aforesaid tie-rods R which, once hooked to the corners A of the tarpaulin and tensioned, tension in turn the tarpaulin itself.
This mounting mode allows the tarpaulin to stretch perfectly across its entire surface.
Unlike retractable shade sails, fixed shade sails are intended to remain stably in an extended condition, exposed to atmospheric agents.
In order to avoid water stagnation from forming in the centre of the tarpaulin in the event of rain, the tarpaulin itself is generally installed with a predefined inclination, so as to allow natural water drainage.
In some cases, the problem of water stagnation is solved by equipping the tarpaulin with rigid support elements that are inserted into special tubular seats created on the tarpaulin itself and pass therethrough. The tarpaulin is thus stiffened, especially in the central area, preventing the tarpaulin itself from sagging under the weight of the water, instead promoting drainage thereof without needing to incline the tarpaulin.
An example of such a solution is described in German utility model application DE202015100767.
Such a technical solution necessarily requires providing tubular seats on the tarpaulin, as well as a plurality of rigid support elements. However, this results in increased production costs, as well as greater installation complexity.
In the field of shade sails, a need is thus felt to provide a fixed shade sail adapted to allow water drainage without being mounted with inclination while not requiring rigid support elements, so as to be less costly to manufacture and easier to install.
Therefore, it is the main object of the present invention to eliminate, in whole or in part, the drawbacks of the above-mentioned prior art by providing a fixed shade sail which allows for the water drainage without being mounted with inclination while not requiring rigid support elements.
It is a further object of the present invention to provide a fixed shade sail which is simple and inexpensive to manufacture.
It is a further object of the present invention to provide a fixed shade sail which is simple and easy to install.

The fixed shade sail according to the invention is indicated as a whole by numeral 1 in the accompanying Figures.
Here and in the following description and claims, reference will be made to the fixed shade sail 1 in conditions of use. Any references to a lower or upper position, or to a horizontal or vertical orientation, should thus be interpreted in this sense. According to a general embodiment of the invention, the fixed shade sail 1 comprises a tarpaulin 10 on which there are identified:
In particular, the tarpaulin 10 can be made of textile material, in particular polyester, polypropylene, polyethylene, or acrylic fabric.
The fixed shade sail 1 further comprises:
In particular, the main tie-rods can be metal cables or ropes.
In the accompanying figures, the supports 50 are poles anchored directly to the ground; these supports can alternatively be masonry works. In general, the supports 50 can be any element capable of stably supporting the sail 1.
According to the present invention, as shown in particular in FIGS. 4, 5, 9, 10, 12, and 14, the fixed shade sail 1 comprises at least one secondary tie-rod 30 of flexible type.
Such at least one secondary tie-rod 30 is arranged at the lower face 10′ of the tarpaulin 10 (i.e., below the tarpaulin itself), unlike the main tie-rods which extend externally with respect to the tarpaulin.
The secondary tie-rod 30 can be anchored either directly or indirectly to the tarpaulin 10, close to or at its two ends 30′, 30″.
The phrase “anchored or anchorable directly to the tarpaulin” means that the connection means act directly between the secondary tie-rod and the tarpaulin.
The phrase “anchored or anchorable indirectly to the tarpaulin” means that the connection means act between the secondary tie-rod and a further intermediate element which, in turn, is connected to the tarpaulin. Preferably, as will be discussed hereinafter, such an intermediate element consists of one of said anchoring bodies 11, 12, 13, 14.
The length L of said secondary tie-rod 30 between the points of direct or indirect connection with the tarpaulin 10 is adjustable through tensioning means 40 so that the secondary tie-rod 30 can be taut between two different portions of the tarpaulin until it adheres to the lower face 10′ of the tarpaulin 10.
Such two portions of the tarpaulin 10 are chosen so that the secondary tie-rod 30 passes at least close to the central area of the tarpaulin 10 and acts as a support element for the tarpaulin itself.
Operatively, the secondary tie-rod 30 can serve its support function because it is tensionable below the tarpaulin until it adheres thereto.
By virtue of the present invention, i.e., of the presence of the tensionable secondary tie-rod 30, the fixed shade sail 1 can be provided with a support rib that stiffens the central area of the tarpaulin. The tarpaulin 10 is thus less prone to bending under the weight of rainwater and can thus ensure the drainage of the water itself without necessarily requiring installation with inclination.
Unlike the prior art, such a result is achieved without the need to use rigid support elements. In fact, the support element is obtained by tensioning a flexible element below the tarpaulin (i.e., the secondary tie-rod), and not by using elongated bodies having intrinsic longitudinal rigidity.
This also makes the fixed shade sail 1 according to the invention simpler and more cost-effective to manufacture.
Furthermore, the absence of rigid support elements (such as fiberglass or carbon bars, for example) reduces the minimum size of a possible packaging for shipment of the disassembled sail. This is advantageous for the simplification of logistics and the reduction of transport costs.
Moreover, the absence of rigid support elements simplifies and facilitates the operations of installing the fixed shade sail. In fact, a flexible element is easier to move and adapts more easily during the assembly.
Furthermore, as will become more apparent from the following description, the use of a flexible element (tensionable between two portions of the tarpaulin) does not require the provision of housing seats on the tarpaulin, which are generally necessary for the application of rigid support elements to the tarpaulin.
Preferably, as shown in particular in FIGS. 6, 7, and 10, each of said anchoring bodies 11, 12, 13, 14 is stably fixed to the tarpaulin 10 and defines a first seat 61 for coupling the respective main tie-rod 21, 22, 23, 24.
Advantageously, as shown in the accompanying figures, each anchoring body 11, 12, 13, 14 can consist of a shaped plate, preferably made of metal, on which are obtained:
In more detail, as shown in FIGS. 6, 7, and 10, the tarpaulin 10 is provided with peripheral reinforcement webbings 15, which in predefined positions along the peripheral edge 16 of the tarpaulin 10 are passed through the second seat 62 of the shaped plates forming the anchoring bodies 11, 12, 13, 14.
Preferably, the tarpaulin 10 is polygonal in shape and has a plurality of corner portions 110, 120, 130, 140 along its peripheral edge 16.
For example, the tarpaulin 10 can be triangular or quadrangular in shape (as shown in the accompanying Figures). Other polygonal shapes, either regular or irregular, can also be provided.
Preferably, as shown in the accompanying Figures, each of said anchoring bodies 11, 12, 13, 14 is connected to the tarpaulin 10 at said corner portions 110, 120, 130, 140. The tarpaulin is thus taut by traction forces applied at the corner portions.
According to alternative embodiments not shown in the accompanying figures, the shade sail 1 may comprise two or more secondary tie-rods placed below the tarpaulin 10 and adhered thereto. Such two or more tie-rods can intersect each other or not. Reference will be made below to the case of a single secondary tie-rod. It is understood that the description given for a single secondary tie-rod also extends to any secondary tie-rods.
The secondary tie-rod can be anchored directly to the tarpaulin in any part of the tarpaulin itself. However, the secondary tie-rod is preferably anchored directly to the tarpaulin close to the anchoring bodies 11, 12, 13, 14, as it is a more resistant part of the tarpaulin. Reference will thus be made below to this direct connection only.
Similarly, the secondary tie-rod can be anchored indirectly to the tarpaulin by means of any intermediate element interposed between the tarpaulin and the tie-rod. However, the secondary tie-rod is preferably anchored indirectly to the tarpaulin at the anchoring bodies 11, 12, 13, 14, as they are a part of the shade sail connected to the tarpaulin in a stable and resistant manner. Reference will thus be made below to such an indirect connection only.
Advantageously, the at least one secondary tie-rod 30 can be anchored, at both of its two ends:
Alternatively, as shown in FIG. 12, the secondary tie-rod 30 can be anchored:
Preferably, as shown in particular in FIGS. 3, 4, 9, 12, 14, and 16-18, said secondary tie-rod 30 is anchored to the tarpaulin close to or at two of said anchoring bodies 12 and 14, the line of junction of which is substantially aligned with the respective main tie-rods 22 and 24. The tension applied by the secondary tie-rod 30 to the tarpaulin 10 can thus be balanced by the opposite tension applied by the main tie-rods to the tarpaulin itself.
Said secondary tie-rod 30 is operatively associated with said tensioning means 40 adapted to adjust the length of said tie-rod between two ends 30′, 30″ of the tie-rod itself.
As for the secondary tie-rod, two cases can be provided:
The case of a secondary tie-rod consisting of a single body is now considered.
In accordance with the embodiments shown in FIGS. 3, 9, and 12, the secondary tie-rod 30 consists of a single elongated body 300 extending seamlessly between the two tie-rod ends 30′, 30 at which it is anchored and/or anchorable either directly or indirectly to the tarpaulin 10.
Advantageously, as diagrammatically shown in FIG. 16, said single elongated body 300 is anchored or anchorable in an adjustable manner to the tarpaulin 10 at both ends 30′, 30″ by means of two separate tensioning devices 41, 42 that form said tensioning means 40.
Preferably, as shown in FIGS. 3 and 9, said single elongated body 300 is anchored or anchorable in an adjustable manner indirectly to the tarpaulin 10 at both ends 30′, 30″ thereof at two of said anchoring bodies. In this case, the two separate tensioning devices 41, 42 are integrated or connected to the respective anchoring body 11, 12, 13, 14.
Alternatively, said single elongated body 300 is anchored or anchorable in an adjustable manner directly to the tarpaulin 10 at both ends 30′, 30″ close to two of said anchoring bodies. In such a case, the two separate tensioning devices 41, 42 are separate from the respective anchoring body 11, 12, 13, 14.
Alternatively, as shown in FIG. 12 and diagrammatically also in FIG. 17, said single elongated body 300:
The case of a secondary tie-rod consisting of at least two elongated bodies connected to each other is now considered.
According to the embodiment shown in FIG. 14 and diagrammatically also in FIG. 18, the secondary tie-rod 30 consists of two elongated bodies 311, 312 each of which:
In this latter case, the tensioning device 43 is distinct from the anchoring elements. In particular, as shown in FIG. 15a, the tensioning device can be a buckle.
Preferably, the two elongated bodies 311, 312 are anchored or anchorable either directly or indirectly to the tarpaulin 10 at the respective first end 311′, 312′ close to or at one of said anchoring bodies 11, 12, 13, 14, respectively.
According to a particularly preferred embodiment, shown in particular in FIGS. 3 to 8b, the secondary tie-rod 30 can be a webbing, understood as a band-shaped body.
Such a solution applies when the secondary tie-rod 30 consists of a single elongated body 300 or consists of two elongated bodies 311, 312.
Preferably, the webbing (or band-shaped body) is made of textile material.
Preferably, the textile material is a polyester fabric that ensures high strength; however, as an alternative, it is possible to use fabrics made of other materials that ensure adequate tensile strength.
If the secondary tie-rod 30 is a webbing, it is anchored or anchorable directly to the tarpaulin 10 by stitching, Velcro, or buttons.
In more detail, in the case of anchoring by stitching, the anchoring is not adjustable, whereas it is adjustable in the case of anchoring by means of Velcro or buttons.
Again, if the secondary tie-rod 30 is a webbing, it is anchored or anchorable indirectly to the tarpaulin 10 by means of buckles, Velcro, or buttons, preferably integrated or connected to said anchoring bodies 11, 12, 13, 14. Such anchoring means (buckles, buttons, and Velcro) allow for adjustable anchoring and also form the tensioning means for the tie-rod.
According to a completely preferred embodiment shown in FIGS. 3 to 8b, said tensioning device is a buckle, integrated into an anchoring body 11-14.
In particular, as shown in FIGS. 6, 7, and 8b, the buckle is defined by a plurality of through openings 63 (preferably consisting of slots) that are obtained in the shaped plate of the anchoring body and through which the secondary tie-rod 30 in the form of a webbing can be passed, tensioning it and securing it when taut.
According to an alternative embodiment, shown in particular in FIGS. 9 to 11, the secondary tie-rod 30 can be a rope, a line, or a metal cable.
Such a solution applies when the secondary tie-rod 30 consists of a single elongated body 300 or consists of two elongated bodies 311, 312.
Preferably, as shown in FIG. 10, if the secondary tie-rod 30 is a rope, a line, or a metal cable, it is anchored or anchorable indirectly to the tarpaulin 10 at an anchoring body 11-14.
Operatively, the tensioning of the tie-rod 30 is obtained by passing it through two holes 64, 65 obtained on the shaped plate that forms the anchoring body, and then securing it by means of at least one U-bolt clamp 70.
Advantageously, the secondary tie-rod 30 in the form of a rope or cable can be provided with an additional tensioning device, consisting of a tensioner, a gas spring, and/or a spring.
