Description

[0001] The invention relates to a parasol.

[0002] Parasols, particularly standing parasols with a parasol crown and canopy struts or ribs, have been widely used for providing shade and protection from the sun in outdoor settings. Conventional parasols typically feature a central pole or a free-arm type of parasol supporting a crown from which multiple canopy ribs radiate outward. These canopy ribs are often connected to supporting ribs via hinges or joints to allow for opening and closing of the parasol. One problem associated with traditional parasol designs is the risk of damaging the canopy fabric. The connections between canopy ribs and supporting ribs often involve exposed metal components with sharp edges or moving parts that can catch, tear, or wear the fabric over time. This not only affects the aesthetics of the parasol but can also compromise its functionality and longevity. Existing solutions to this problem have included covering the metal components with plastic caps or sleeves. However, these add-on components can detract from the overall appearance of the parasol and may become loose or fall off over time. Another approach has been to design more streamlined connections, but these often sacrifice structural integrity or ease of operation. Another drawback of conventional parasols is the potential for user injury. The articulation points between struts can create pinch points where fingers or other body parts may get caught during opening or closing of the parasol. This safety concern is particularly relevant in commercial settings where parasols may be operated by untrained individuals. Some manufacturers have attempted to address this by incorporating safety mechanisms or redesigning the folding mechanism. However, these solutions often result in more complex designs that are costlier to produce and may be more prone to mechanical failure.

[0003] It is therefore an object of the present invention to provide an improved parasol that minimizes the risk of damage to the canopy fabric while maintaining structural integrity and ease of operation, or at least to provide an alternative to the existing parasols.

[0004] The invention provides thereto a parasol, comprising: a plurality of canopy ribs to which at least one canopy can be attached; and a plurality of supporting ribs configured to co-act with the canopy ribs, wherein the parasol and in particular the canopy ribs and the supporting ribs, are displaceable between at least one folded position and at least one unfolded position; wherein at least one canopy rib and at least one supporting rib are mutually connected via at least one coupling structure, wherein the at least one coupling structure comprises: ∘ at least one first connector which is connected or configured to be connected to at least one canopy rib; and ∘ at least one second connector which is connected to or configured to be connected to at least one supporting rib; and ∘ at least one hinge which hingeably connects the at least one supporting rib to the at least one canopy rib via the at least one coupling structure.

[0005] Preferably, at least one first connector and at least one second connector are mutually connected via at least one angled and / or curved profile in particular such that the at least one first connector and the at least one second connector are positioned at opposing sides of the at least one angled and / or curved profile.

[0006] The parasol according to the invention has several benefits over conventional parasols. A key aspect of the invention is the connection between at least one canopy rib and at least one supporting rib via a coupling structure. This coupling structure comprises at least two main components: a first connector and a second connector. The first connector is configured to be connected to at least one canopy rib, while the second connector is configured to be connected to at least one supporting rib. It is beneficial that at least part of the at least one coupling structure defines an angle and / or curvature as this results in that the coupling structure can ensure correct positioning of the supporting rib with respect to the canopy rib. Basically, the coupling structure comprises or defines an angled and / or curved profile which mutually connects the first connector and the second connector. The first connector and the second connector are positioned on opposing sides of the angled and / or curved profile. This angled configuration provides several benefits, such as improved stability, enhanced force distribution, and a more streamlined appearance when the parasol is in use. The coupling structure, and possibly second connector of the coupling structure, comprises at least one hinge. This hinge enables the supporting rib to be hingeably connected to the canopy rib via the coupling structure. The hinged connection allows for smooth and controlled movement of the supporting rib relative to the canopy rib during the opening and closing of the parasol. Since the hinge is present at an opposing side of the angled and / or curved profile than the first connector which is connected to the canopy rib, the supporting rib is positioned at a desired distance from the canopy rib.

[0007] Further, the configuration of the parasol according to the invention also enhances the durability of the parasol through reduced stress on components and smoother operation for better user experience. The configuration using the coupling structure according to the invention may also allow for more compact folding when not in use, potentially reduce wear on the canopy fabric by minimizing friction points, and provide opportunities for customization or easy replacement of components. Collectively, these features aim to create a more efficient, durable, and user-friendly parasol that addresses common issues found in conventional designs while potentially extending the product's lifespan.

[0008] The parasol typically comprises multiple canopy ribs and multiple supporting ribs. As indicated the parasol can be changed from a folded position to an unfolded position, and vice versa. Therefore, both the canopy ribs and the supporting ribs are displaceable between at least one folded position and at least one unfolded position. In line with the conventional parasols, this feature allows the parasol to be compactly stored when not in use and easily deployed when shade is desired. When it is referred to a rib, also a strut can be meant. When it is referred to a canopy rib, also an outer rib can be meant and / or when it is referred to a supporting rib an inner rib can be meant. Typically the canopy ribs are longer than the supporting ribs. The parasol structure is typically formed at least partially by the canopy ribs and the supporting ribs which are present in a configuration. The canopy ribs typically extend outward from a central point, typically the parasol crown, in a spoke-like arrangement. This radial layout allows for even distribution of the canopy fabric when the parasol is opened, providing optimal shade coverage. The supporting ribs, or inner ribs, are similarly arranged in a radial pattern, working in conjunction with the canopy ribs. This complementary radial configuration of both sets of ribs enables the parasol to open and close smoothly, maintaining structural integrity in both the folded and unfolded positions. The radial arrangement also allows for efficient force distribution throughout the parasol structure, enhancing its stability and resistance to wind forces when deployed. This design approach maximizes the parasol's functionality while allowing for a symmetrical and aesthetically pleasing appearance.

[0009] The at least one coupling structure may have an elongated configuration or may define a length direction. The coupling structure may comprise two distal ends. It is possible that a distal end of the at least one coupling structure comprises the connector which is connected or connectable to at least one canopy rib and that a second distal end of the at least one coupling structure comprises at least one hinge which is connected or connectable to at least one supporting rib.

[0010] Preferably, each canopy rib is connected to a single supporting rib via a coupling structure. Hence, the parasol may be configured such that each canopy rib is paired with a corresponding supporting rib through a dedicated coupling structure. Alternatively, the parasol may be designed with multiple supporting ribs connected to a single canopy rib, or vice versa. The design and configuration of the canopy ribs and supporting ribs may depend on the desired structural characteristics and folding mechanism. For example in another possible embodiment, the coupling structure may connect groups of canopy ribs to groups of supporting ribs, potentially allowing for a more complex or segmented canopy design. The specific configuration of rib connections may vary based on factors such as the size of the parasol, the intended use, and the desired balance between structural stability and ease of operation.

[0011] At least part of the at least one coupling structure preferably has an angled configuration and / or an angled profile. It is for example possible that the part of at least one coupling structure is located between a first distal end and a second distal end thereof defines an angled profile. The coupling structure may for example have a non-linear geometry, where the first connector and the second connector are oriented in different planes or directions. This configuration creates an angled, bent, curved and / or kinked profile within the coupling structure. The first connector and the second connector may be positioned such that they form a vertex or apex point between them, resulting in a change of direction within the coupling structure. This non-planar arrangement allows the coupling structure to transition between the orientation of the canopy rib and the orientation of the supporting rib, potentially facilitating a more compact folding mechanism or providing improved structural support when the parasol is deployed. When it is referred to an angle, also a curvature can be meant. The angled profile may comprise a curved angle or rounded angle. The specific angle or curvature between the connectors can be designed to optimize the parasol's opening and closing action, its stability when open, or its folded profile when closed. This non-linear configuration may also contribute to the overall aesthetic of the parasol, potentially creating a more streamlined or modern appearance compared to traditional straight-line connections between ribs.

[0012] The at least one angled profile preferably imposes a height difference between the at least one first connector and the at least one second connector. This enables that the supporting rib can be positioned at a desired distance from the canopy rib. It is for example possible that the angled profile has a stepped configuration.

[0013] At least one angle defined by at least part of the at least one coupling structure, and in particular the angled profile thereof is preferably 90 degrees or smaller. It is for example possible that a least part of the at least one angled profile defines a rectangular angle or an acute angle. Basically, the at least one coupling structure may incorporate various angular configurations between the first connector and the second connector. In a possible embodiment, the angle formed by the angled profile between the first connector and the second connector may be 90 degrees or less, creating a right angle or an acute angle. Alternatively, the angle may be obtuse, exceeding 90 degrees, to accommodate different folding mechanisms or structural requirements. In other implementations, the coupling structure may feature a curved or arcuate profile instead of a distinct angle, allowing for a smooth transition between the canopy rib and supporting rib orientations. The specific angle or curvature can be tailored to optimize the parasol's performance characteristics, such as its ability to withstand wind loads, its folding compactness, or its ease of operation. By varying this geometric feature, manufacturers can finetune the balance between structural integrity and user-friendly operation.

[0014] It is possible that at least one coupling structure comprises at least one bridge element. At least part of the at least one bridge element may define an angle. Possibly, at least one bridge element forms the at least one angled profile. It is also possible that at least part of the at least one coupling structure defines at least one bridge element, in particular a bridge element between the at least one first connector and the at least one second connector. At least one bridge element, which may define an angle, may enhance the structural integrity of the parasol by providing additional support and stability to the connection between the canopy rib and the supporting rib. The angled configuration of the coupling structure, and in particular of the bridge element may allow for improved force distribution, potentially reducing stress on individual components and increasing the overall durability of the parasol. It is also conceivable that the bridge element comprises a curved profile and / or a rounded angle profile offering different mechanical properties or aesthetic appeal. In some implementations, the bridge element may be adjustable, for example in length. This embodiment may allow users to modify the angle to suit different weather conditions or shade requirements. Additionally, the bridge element may serve as a mounting point for additional features like LED lights, speakers, or sensors, expanding the parasol's functionality beyond simple sun protection.

[0015] In a preferred embodiment, at least one first connector is connected to an outer circumference of at least one canopy rib. The configuration where at least one first connector is attached to the outer circumference of at least one canopy rib offers several advantages and allows for various design alternatives. This external attachment may facilitate easier assembly and maintenance, as it provides direct access to the connection point without the need to disassemble the rib structure. It further wont affect the strength of the canopy strength. Alternatively, the first connector could be partially recessed into the canopy rib, maintaining a streamlined profile while still allowing for external access. However, a drawback of this configuration is that reinforcement ribs, which are often applied within the canopy rib, cannot be applied over the entire length of the canopy rib. Therefore, it is preferred that the first connector is attached to an outer surface of the at least one canopy rib. In a possible embodiment, the first connector at least partially encloses or wraps around the circumference of the canopy rib. In this configuration, distributing forces more evenly and potentially increasing durability. The external positioning may also allow for the use of different materials or finishes for the connector, enhancing aesthetic appeal or providing additional functionality such as UV resistance or water repellency. This configuration could enable modular designs where connectors can be easily swapped out to change the parasol's appearance or functionality. Additionally, the external attachment may provide more flexibility in rib design, potentially allowing for the use of solid rib profiles or alternative materials that might be challenging to work with using internal connection methods.

[0016] At least one first connector is typically a static connector. The first connector can also be referred to as static connector. Possibly, at least one first connector is connected to at least one canopy rib via at least one mechanical fixing element, such as but not limited to a screw or rivet. The connection between the first connector and the canopy rib may be achieved through various mechanical fixing elements, offering different benefits and design alternatives. Screws may be used, allowing for easy disassembly and replacement of components, which can be advantageous for maintenance or upgrades. Alternatively, rivets could provide a more permanent and potentially more streamlined connection, reducing the risk of loosening over time. In some implementations, a combination of fixing methods might be employed, such as adhesive bonding reinforced with mechanical fasteners, potentially offering superior strength and vibration resistance. The choice of fixing element may depend on factors such as the material of the canopy rib, expected loads, and manufacturing processes. For instance, if the supporting rib is substantially hollow, this may influence the selection of fixing methods, potentially favouring those that don't require significant material thickness for engagement. Other alternatives could include snap-fit connections for tool-less assembly, welding for metal components, or integrated molded features that eliminate the need for separate fasteners altogether. The second connector can be a movable connector.

[0017] At least one supporting rib, and possibly each supporting rib may be substantially hollow. This may for example be beneficial for the overall weight of the parasol. It is conceivable that at least part of at least one coupling structure is received within at least part of at least one supporting rib. It is for example conceivable that at least part of the at least one hinge is received within at least one supporting rib. The configuration where at least part of the coupling structure and / or the hinge thereof is received within a substantially hollow supporting rib offers several advantages and design alternatives. This configuration can provide protection for the coupling structure or hinge from environmental factors such as moisture, dust, or UV radiation, potentially extending the parasol's lifespan. This configuration may further create a more streamlined and aesthetically pleasing appearance. It is for example possible that at least one supporting rib substantially encloses at least part of the at least one coupling structure, in particular at least part of the at least one hinge.

[0018] In a possible embodiment, the internal space of the hollow rib might be utilized for routing cables or housing additional features like LED lighting or heating elements. The hollow design may also allow for modular construction, where different coupling structures or hinges can be easily swapped out for repair or to modify the parasol's functionality. Additionally, this configuration could facilitate the use of internal reinforcement elements or damping mechanisms to improve the parasol's stability and operation. The hollow rib design may also contribute to weight reduction without compromising strength, potentially making the parasol easier to displace or transport.

[0019] At least one coupling structure may be releasably connected to at least one supporting rib. It is for example possible that at least one coupling structure is connected to at least one supporting rib via a snap connection. The use of a snap connection to attach the coupling structure to the supporting rib allows for quick and tool-free assembly or disassembly, potentially simplifying manufacturing processes and enabling easier maintenance or replacement of components. Possibly, the snap connection might incorporate multiple engagement points for enhanced stability, or be combined with other fastening methods for redundancy. The design could also include audible or tactile feedback mechanisms to confirm proper engagement. Snap connections may be molded directly into the components, reducing part count and potentially lowering production costs. Additionally, this type of connection could facilitate modular designs, allowing users to easily customize or upgrade their parasol by swapping out different supporting ribs or coupling structures. The snap connection might also be engineered to act as a safety feature, designed to disengage under extreme loads to prevent damage to other parasol components.

[0020] It is possible that at least one first connector is integrally connected to part of the coupling structure defining the at least one angled profile. Such embodiment will be beneficial for the strength and structural integrity of the coupling structure. The integral connection could potentially simplify the manufacturing process by reducing the number of separate parts and assembly steps. Additionally, this configuration may provide improved resistance to environmental factors by eliminating seams or joints where moisture or debris could accumulate. The integrated design might also offer opportunities for creating more organic, flowing shapes that could enhance the parasol's overall aesthetic appeal while maintaining its functional requirements. It is for example possible that the coupling structure comprises at least two or at least three components, depending on the number of hinge parts applied for the second connector.

[0021] In a possible embodiment, at least one coupling structure is dimensionally stable and / or substantially rigid. The dimensionally stable and / or substantially rigid coupling structure may be achieved through various materials and manufacturing techniques, offering several benefits and design alternatives. It is for example possible that at least part of at least one coupling structure is made of metal, a composite material and / or of at least one polymer. The material may be fiber-reinforced. For example, the coupling structure could be made from high-strength aluminum alloys, providing decent rigidity while maintaining a lightweight profile. Alternatively, advanced composite materials such as carbon fiber-reinforced polymers might be used, offering superior strength-to-weight ratios and the potential for customized mechanical properties.

[0022] The canopy ribs and the supporting ribs typically have an elongated configuration. The canopy ribs and the supporting ribs typically define a width and a length. It is conceivable that the width of at least one coupling structure is smaller than the width of at least one canopy rib and / or the width of at least one supporting rib. The coupling structure with a width smaller than both the canopy rib and supporting rib may allow for a sleeker, more streamlined appearance of the parasol when folded, potentially reducing its storage footprint. At least part of the coupling structure could for example have a tapered profile, transitioning smoothly from the wider ribs to create an aesthetically pleasing silhouette. The angled design of the coupling structure with a first connector extending in the length direction of the canopy rib may provide improved force distribution and stability. This design could incorporate two distal ends: one end connecting to the canopy rib and the other to the supporting rib, with the angle between them optimized for efficient load transfer. Alternatively, the coupling structure might feature a modular design with interchangeable connectors, allowing for easy customization or replacement of specific components. The narrower width could also facilitate the integration of internal mechanisms, such as tension adjusters or automatic locking systems, without increasing the overall profile of the parasol structure.

[0023] At least one hinge is preferably configured to provide a hinging movement between the canopy rib and the supporting rib via the coupling structure provided between them. With a hinging movement a pivoting movement around a fixed axis is meant. The movement is typically reversible, allowing for both opening and closing actions of the hinge. The hinging movement occurs around a pivot axis, which can for example be formed by a pivot pin. The length direction of the pivot pin may define the pivot axis. The hinge supports the weight and forces acting on the connected canopy rib and supporting rib during movement, providing a controlled and predictable path of motion that is essential for the parasol's functionality and ease of use. The hinge thereto restricts movement of the ribs in other planes. At least one hinge for example comprises at least one pivot pin. The incorporation of at least one pivot pin in the hinge mechanism offers several benefits and design alternatives for the parasol structure. This configuration may provide a precise axis of movement, ensuring smooth and consistent movement during opening and closing operations. The at least one coupling structure may possibly comprise at least one damping mechanism. Further, the opposing ends of the supporting ribs and / or the canopy ribs could also be movably and / or hingeably connected to further parasol parts, such as a shaft or crown.

[0024] At least one hinge can form part of the coupling structure, and optionally of the second connector thereof. At least one hinge is preferably connected to a distal end of at least one supporting rib. In a possible embodiment, at least one coupling structure comprises at least one spring element configured for co-acting with the at least one hinge. At least one spring element may for example be a torsion spring, a leaf spring, and / or a coil spring. The incorporation of at least one spring element configured to co-act with the hinge further enhances the parasol's performance. This spring element may assist in the opening and closing actions, reducing the effort required by the user. It could also help maintain tension in the canopy fabric when deployed, improving its appearance and effectiveness. The spring element might be designed as a torsion spring, providing rotational force around the hinge axis. Alternatively, a leaf spring could be used for its compact profile and ability to provide force in a specific direction. A coil spring is another option, offering the potential for adjustable tension and easy replacement. In some implementations, a combination of spring types might be used to achieve specific performance characteristics. The spring element could also serve as, or even be, a damping mechanism, preventing abrupt movements and reducing wear on other components.

[0025] The parasol may comprise at least one cover for covering at least part of at least one coupling structure and preferably of the at least one hinge. It is conceivable that at least one cover is attached or attachable to at least one supporting rib. It is for example possible that at least one cover follows the shape and / or configuration of at least part of the at least one supporting rib. The cover may also be made of the same material as the supporting ribs. This may enhance the parasol's aesthetic appeal by concealing mechanical components. The cover might be a separate, removable element, allowing for easy access to the hinge for maintenance or replacement. In some implementations, the cover could be made of a flexible material that expands and contracts with the hinge movement, providing continuous protection without impeding functionality. The cover may serve multiple purposes beyond aesthetics, such as protecting the hinge mechanism from environmental factors like dust, moisture, or UV radiation, potentially extending the parasol's lifespan. It could also act as a safety feature, preventing pinch points and reducing the risk of injury during operation.

[0026] The parasol according to the invention may comprise at least one canopy. Preferably said canopy is attached or attachable to at least one canopy rib and preferably to multiple canopy ribs. Various types of canopies may be employed to suit different needs and environments. A UV-resistant fabric canopy may offer superior sun protection, ideal for prolonged outdoor use. Waterproof canopies, often made from materials like polyester with special coatings, can provide shelter during light rain showers. For versatility, some designs might feature reversible canopies with different colors or patterns on each side. Breathable mesh canopies could be used in hot climates to allow air circulation while still providing shade. Eco-friendly options may include canopies made from recycled materials or organic fabrics. For enhanced durability, reinforced canopies with additional stitching or protective edging might be employed. Some high-end models could feature canopies with integrated solar panels for energy harvesting or smart fabrics that can change opacity based on sunlight intensity. In commercial settings, fire-resistant canopies may be preferred for safety reasons. The attachment method of the canopy to the ribs may vary, including options like sewn-in pockets, snap fasteners, or tensioning systems, each offering different benefits in terms of ease of installation, replacement, and overall canopy tension.

[0027] The canopy ribs and supporting ribs of the parasol can be fabricated from a variety of materials such as but not limited to metal, wood, composites, polymers and / or combinations thereof. For a more eco-friendly approach, sustainable materials like bamboo or other engineered wood products could be considered for certain components. The parasol according to the invention may further comprise a shaft and / or a crown. A shaft, typically a central pole, could provide the main support for the entire parasol structure, allowing for stable deployment in various settings. This shaft may be designed with adjustable height features, enabling users to customize the parasol's elevation to suit different environments or user preferences. The crown, typically situated at the top of the shaft, may serve as a central hub from which the canopy ribs radiate. This crown could be engineered to incorporate various mechanisms for smooth opening and closing of the parasol, such as a sliding system or a geared mechanism. In certain designs, the crown might feature additional functionalities like integrated lighting, speakers, or climate control elements. The material composition of the shaft and crown may vary, ranging from lightweight aluminium for portability to robust stainless steel for enhanced durability in commercial settings. Some advanced models might incorporate smart technologies within the shaft or crown, such as automated opening systems or sensors for wind speed detection to enhance safety. The connection between the shaft and crown could be designed to allow for tilting or rotation of the canopy, providing more versatile sun protection throughout the day.

[0028] The invention also relates to a coupling structure as described for use in a parasol according to the invention. Such coupling structure can be any formed according to any of the described embodiments.

[0029] The invention will be further elucidated by means of non-limiting exemplary embodiments illustrated in the following figures, in which: figures 1a-1c shows a first possible embodiment of a parasol according to the present invention; figures 2a-2e show the details and functioning of a coupling structure according to the present invention; figures 3a and 3b show a third possible embodiment of two ribs which are connected via a coupling structure according to the present invention; and figures 4a-4c show various views of components for use in a parasol according to the present invention.

[0030] Within these figures, similar reference numbers correspond to similar or equivalent elements or features.

[0031] Figures 1a-1c show a first possible embodiment of a parasol 100 according to the present invention. Figure 1a shows a perspective view of the parasol 100 in a configuration wherein a canopy 101 is present. Figure 1b shows the parasol 100 without the canopy revealing more of its internal structure. Figure 1c shows a detailed view of the ribs 102, 103 of the parasol 100. The parasol 100 comprises a plurality of canopy ribs 102 to which the canopy 101 is or can be attached and a plurality of supporting ribs 103 which are configured to co-act with the canopy ribs 102. The parasol 100 and in particular the canopy ribs 102 and the supporting rib 103 are displaceable between at least one folded position and at least one unfolded position. In the shown figures 1a-1c only unfolded positions are shown. In the shown embodiment, the canopy ribs 102 and supporting ribs 103 are mutually connected via coupling structures 104. In the shown embodiment, each canopy rib 102 is connected to an supporting rib 103 via a coupling structure 104. The coupling structures according to the invention are shown in more detail in the further figures. Each coupling structure 104 comprises a first connector which is connected to an canopy rib 102 and a second connector which is connected to an supporting rib 103. Since the coupling structure 104 has an angled profile and comprises at least one hinge, the supporting ribs 103 are hingeably connected to the coupling structures 104 in a smart configuration. In the shown embodiment, the parasol 100 is positioned under an angle. However, it most be noted that when the rib structure is observed from underneath, when sitting under the parasol 100, the coupling structures 104 are not or barely visible.

[0032] The parasol 100 further comprises a shaft 105. The shaft 105 is connected to both the canopy ribs 102 and the supporting ribs 103 via connecting hubs. In the shown embodiment, the parasol 100 is a free-arm type of parasol. However, the invention is also applicable for center pole parasol or other types of parasols. In the shown embodiment, the parasol 100 is mounted on a base with wheels for mobility. The supporting ribs 103 are shorter than the canopy ribs 102 and are positioned at an angle to provide additional support and stability to the parasol structure. The connection between each canopy rib 102 and its corresponding supporting rib 103 is facilitated by a coupling structure 104. The coupling structure 104 is a pivotal component that allows for the folding and unfolding of the parasol 100. It connects the outer end of each supporting rib 103 to a point along the length of each canopy rib 102, creating a triangular support structure. This arrangement enables the parasol 100 to maintain its shape when open and allows for compact folding when closed. The parasol 100 appears to have a symmetrical design, with the canopy ribs 102, supporting ribs 103, and coupling structures 104 arranged in a radial pattern around the central shaft 105. This configuration provides balanced support for the canopy 101 and ensures even distribution of forces when the parasol 100 is in use.

[0033] Figures 2a-2e show different view of the functioning of the coupling structure 204 as applied in a parasol according to the present invention. Figure 2a shows an exploded view and figures 2b-2e show assembled views. The figure shows that a canopy rib 202 and a supporting rib 203 connected via a coupling structure 204. The coupling structure 204 includes a first connector 206 and a second connector 207 which are separated by an angled profile formed by part of the coupling structure 204. The angled profile of the coupling structure 204 imposes a height difference between the at least one first connector 206 and the at least one second connector 207. The first connector 206 is attached to the canopy rib 202 using screws 212. The second connector 207 forms part of a hinge 208 that connects to the supporting rib 203. A pivot pin 209 allows rotational movement between the first connector 206 and second connector 207. Optionally, a spring element 210 is incorporated into the hinge 208, potentially providing tension or assisting with the opening / closing action of the parasol. A cover 211 encloses the hinge 208 and internal components. This cover 211 may serve to protect the mechanism and provide a smoother aesthetic appearance. As can be seen in figure 2b, the components fit together to form a compact connection between the canopy rib 202 and supporting rib 203. The coupling structure 204 creates an angled joint between these two elements, which likely facilitates the folding and unfolding action of the parasol. The design allows for a hinged connection between the canopy rib 202 and supporting rib 203 while maintaining a streamlined appearance. The use of the coupling structure 204 with its integrated hinge 208 enables the necessary movement for parasol operation. Figures 2c, 2d and 2e illustrate orthogonal views of a parasol hinge mechanism in different positions. The figures show that the coupling structure 204 according to the invention facilitates the folding and unfolding of the parasol. The canopy rib 202 is shown as a hollow tubular structure. Connected to the canopy rib 202 is the first connector 206, which forms part of the coupling structure 204. The coupling structure 204 is an angled component that connects the canopy rib 202 to the supporting rib 205. A pivot pin 209 is visible in the coupling structure 204, allowing for rotational movement between the first connector 206 and the second connector 207. This pivoting action enables the folding and unfolding of the parasol. A cover 211 is shown partially enclosing the coupling structure 204 and its components. This cover 211 may serve to protect the internal mechanisms and provide a more streamlined appearance. These figures demonstrate how the components interact to allow for the articulation of the parasol, with the coupling structure 204 serving as the central point of movement between the canopy rib 202 and the supporting rib 205.

[0034] Figures 3a and 3b show a third possible embodiment of two ribs which are connected via a coupling structure according to the present invention. The figures basically illustrate orthogonal views of a parasol rib connection mechanism. The figures show the interaction between a canopy rib 302 and a supporting rib 303, connected by a coupling structure 304. In figure 3a, the canopy rib 302 is shown extending diagonally and the supporting rib 303 is positioned under an angle to the canopy rib 302. The coupling structure 304 connects these two ribs in a pivoting manner. The coupling structure 304 has an angled design or angled profile, with one end attached to the canopy rib 302 and the other end connected to the supporting rib 303. Figure 3b provides a different perspective of the same components. In this view, the canopy rib 302 is substantially parallel to the supporting rib 303 as could occur in a folded configuration of the parasol. A rivet 312 is visible in both figures, securing the coupling structure 304 to the canopy rib 302. This rivet 312 provides a fixed point of attachment while still allowing for the necessary movement of the parasol components.

[0035] Figures 4a-4c show illustrates various views of components for a parasol mechanism. Each figure shows a different embodiment of a coupling structure 404a, 404b, 404c according to the present invention. The figures show the angled profiles of the coupling structures 404a, 404b, 404c. Figures 4a and 4b show isometric views of two coupling structures 404a and 404b, respectively. The first coupling structures 404a is made of sheet metal and the second coupling structure 404b is made of aluminum die cast. The coupling structures 404a, 404b bend at approximately a right angle and terminate in a cylindrical portion, which may serve as a hinge or pivot point.
