[0022] Although the present technical solution elaborates on the specific details of various embodiments, it is understood that this description is for illustrative purposes only and should not be construed as restrictive in any way. In addition, the general concepts described in this technical solution also include various applications and modifications of such embodiments that those skilled in the art may encounter. Each feature described herein, as well as each combination of two or more such features, is included within the scope of the present utility model, provided that the features included in such combination are not mutually contradictory.

[0023] Figure 1 A perspective view of the umbrella assembly 100 in an open configuration is described. As Figure 1 shown, the umbrella assembly 100 may include a base 140, a support rod 110, a lower hub assembly 150, an upper hub 210, umbrella ribs 120, and / or an umbrella canopy 130. The configuration of the base 140 may make the umbrella assembly 100 a freestanding unit. The support rod 110 may be connected to the base 140 at one end and extend vertically to the upper hub 210 disposed and connected to the other end. A locking clamp 116 may be mounted on the support rod 110. The lower hub assembly 150 is movably connected to the support rod 110 and is disposed along the support rod 110 between the base 140 and the upper hub 210. The lower hub assembly 150 may include a locking mechanism 330. The locking mechanism 330 may be configured to engage with the locking clamp 116 to fix the lower hub assembly 150 in an upper position and disengage from the locking clamp 116 to allow the lower hub assembly 150 to move from the upper position to a lower position. One or more umbrella friction pads are rotatably connected to the lower hub assembly 150. The umbrella canopy 130 may be placed on the umbrella ribs 120 to provide a sunshading effect.

[0024] As Figure 2A and 2B shown, the umbrella assembly 100 may move between an open state and a closed state. Figure 2A A partial cross-sectional view of the umbrella assembly 100 in the open state is described. In the open state, the lower hub assembly 150 is located in an upper position near the upper hub 210. Placing the lower hub assembly 150 in a position near the upper position causes the umbrella ribs 120 to move in a direction that is generally horizontal or radially downwardly inclined. When in the open state, the umbrella canopy 130 may be extended to provide sunshading and shelter for the user of the umbrella assembly 100. The umbrella canopy 130 may be composed of at least partially flexible materials such as fabric and / or plastic film. The umbrella canopy 130 may block sunlight and at least partially block rain, bird droppings, tree sap, etc. The umbrella canopy 130 may also be composed of materials having weather and sunlight resistance characteristics to provide longer durability and use in outdoor environments.

[0025] Figure 2BDescribes a partial cross-sectional view of the umbrella assembly 100 in the closed state. In the closed state, compared to the open state, the lower hub assembly 150 is located at a lower position farther from the upper hub 210. Placing the lower hub assembly 150 in the lower position or towards the lower position allows the umbrella ribs 120 to be folded in a substantially vertical direction. When in the closed state, the umbrella assembly 100 occupies a smaller physical space, thus facilitating storage, movement, and / or packaging and transportation.

[0026] Figure 3 Describes a perspective view of the lower hub assembly 150 connected to the support rod 110. By moving the lower hub assembly 150 along the support rod 110 between the upper position and the lower position, the umbrella assembly 100 can be moved between the closed state and the open state. Figure 3 Shows these features with the umbrella ribs 120 removed for clarity, including a cross-sectional view of the lower hub assembly 150. Figure 4 Describes Figure 3 An exploded view of an example assembly of the lower hub assembly 150 therein.

[0027] The support rod 110 provides a structure to which the upper hub 210, the umbrella ribs 120, and the umbrella canopy 130 can be fixed. The lower hub assembly 150 can also be releasably fixed or secured to the support rod 110, allowing movement along the rod, such as sliding or rolling. Additionally, the support rod 110 provides an elongated structure along which the lower hub assembly 150 can move axially to move the umbrella between the open and closed states. The support rod 110 can be an assembly of one or more parts or components. The support rod 110 can have a mounting end 112. The mounting end 112 can be the lower part of the support rod 110, for example, including its lower end. As Figure 1 shown, the mounting end 112 can be configured to be fixed to a base or pedestal 140 on the ground, patio platform, lawn, or other surface. In some embodiments, the base 140 can be built-in or connected to an anchor fastener. In other embodiments, the mounting end 112 can be configured to be directly connected or mounted to a bracket on a terrace, a vertically or horizontally extending building surface, etc. The mounting end 112 can be permanently or semi-permanently fixed to the base 140, the fixed surface, or other ground. In other embodiments, the mounting end 112 can be releasably connected to the base 140, the fixed surface, or other ground. In some embodiments, the connection arrangement of the mounting end 112 can be used to limit the translation and rotation of the support rod 110. In other embodiments, the mounting end 112 can be configured to allow limited rotational movement, such as rotational movement. Therefore, it can be understood that in some embodiments, the mounting end 112 can facilitate the installation of the umbrella assembly 100 in place for using the umbrella assembly 100.

[0028] The support rod 110 can be composed of a generally elongated rigid member. As Figures 1 - 3As shown, the support rod 110 can be generally straight or linear along its length. In other embodiments, the support rod 110 can consist of a straight portion and a bent portion. In other embodiments, the support rod 110 can be generally bent along the entire length of the support rod 110. Figures 1 - 3 The general vertical direction of the support rod 110 is shown. In other embodiments, the support rod 110 can be set at an inclined, diagonal, or horizontal direction according to the requirements of a specific application. The support rod 110 can be generally cylindrical with a circular cross-section. In other embodiments, the support rod 110 can be a rectangular prism, a triangular prism, or any other suitable shape.

[0029] The support rod 110 can include a locking clamp 116. The function of the locking clamp 116 is to fix the lower hub assembly 150 at a specific position or at any of a plurality of positions along the support rod 110. The locking clamp 116 can be mounted on the outer surface of the support rod 110. The locking clamp 116 can include, but is not limited to, holes, grooves, flanges, protrusions, rings, engaging members, steps, ratchets, or similar devices. In certain embodiments, the locking clamp 116 can be a groove or a hole formed in the support rod 110. As Figure 3 and Figure 4 shown, the locking clamp 116 can include an array of linear teeth arranged along the length of the support rod 110, such as ratchet features or a rack. The array of linear teeth can define a plurality of spaced-apart grooves 118 arranged along the length of the support rod 110. Each tooth includes an upward-facing horizontal surface and a downward-facing inclined surface. The locking clamp 116 can include a portion of the wall of the support rod 110. The locking clamp 116 can include a flange or a protrusion provided on the inner surface of the support rod 110. The locking clamp 116 can be accessed through a groove, a hole, a slot, a channel, or a pore in the support rod 110. The locking clamp 116 can be embedded or inserted into the support rod 110 such that the locking clamp 116 does not extend beyond the outer surface of the support rod 110. In the illustrated embodiment, the support rod 110 includes an elongated groove extending along the length of the support rod 110. In the illustrated embodiment, the locking clamp 116 includes an array of linear teeth provided in the elongated groove, such as ratchet features or a rack. The locking clamp 116 is not limited to any specific shape or orientation. The locking clamp 116 can be one or more separate components connected to the support rod 110 by screws, nails, bolts, adhesives, or other fasteners. In certain embodiments, the locking clamp 116 can be integrally formed with the support rod 110.

[0030] As Figure 3 and Figure 4As shown, the lower hub assembly 150 may include a runner hub 200 and a hub controller 300. The runner hub 200 may serve as a central hub, and one or more umbrella ribs 120 may be connected to the runner hub 200. Specifically, the runner hub 200 may include one or more grooves 202 for receiving the umbrella ribs 120. The umbrella ribs 120 may be connected to the runner hub 200 through one or more pivot points disposed within the grooves 202. The dimensions of the plurality of grooves 202 may allow the umbrella ribs 120 to rotate unobstructed. The runner hub 200 may be movably connected to the support rod 110. As Figure 3 shown, the runner hub 200 may form a generally annular shape, and its central channel 206 is configured to receive the support rod 110. When disposed around the support rod 110 through the central channel 206, the runner hub 200 may translate axially along the support rod 110. The runner hub 200 may translate vertically in an upward or downward direction to move the umbrella ribs 120 between the open and closed states. In the illustrated embodiment, the runner hub 200 has eight grooves 202 for receiving eight umbrella ribs 120. In other embodiments, the runner hub 200 may have zero, one, two, three, or any other number of grooves 202 to receive the corresponding number of umbrella ribs 120. In other embodiments, the runner hub 200 may adopt any suitable shape. For example, the runner hub 200 may be generally rectangular, triangular, circular, or other polygonal or arcuate. Additionally, in other embodiments, the central channel 206 may have a different shape to correspond to the shape of the support rod 110. For example, if the support rod 110 has a rectangular cross-section, the central channel 206 may have a rectangular cross-section.

[0031] The hub controller 300 provides a user interface that allows the user to manually move the umbrella assembly 100 between the open and closed states. As Figure 3 shown, the hub controller 300 may be configured to engage with a locking fixture 116 on the support rod 110 to hold the umbrella assembly 100 in the open configuration. The hub controller 300 may include an upper portion 310, a handle portion 320, and a locking mechanism 330.

[0032] Referring to Figure 3 , the hub controller 300 may be connected to the runner hub 200. In certain embodiments, the hub controller 300 may be directly connected to the runner hub 200. As Figure 3As shown, the hub controller 300 can be directly connected to the swivel hub 200 through an upper portion 310 extending from the lower surface 204 of the swivel hub 200. The swivel hub 200, the upper portion 310, and the handle portion 320 can each have a thickness extending along the longitudinal axis A1 of the support rod 110. The upper portion 310 refers to the portion of the hub controller 300 located between the swivel hub 200 and the handle portion 320. As shown in the illustrated embodiment, the thickness of the upper portion 310 can be about 1.3 times the thickness of the swivel hub 200. In other embodiments, the thickness of the upper portion 310 can be less than the thickness of the swivel hub 200. The thickness of the upper portion 310 can be equal to the thickness of the swivel hub 200. The thickness of the upper portion 310 can be greater than the thickness of the swivel hub 200. The thickness of the upper portion 310 can be set to keep the handle portion 320 at a sufficient distance from the swivel hub 200 to provide a space clearance for the user to be able to hold the handle portion 320 with a hand. The upper portion 310 can extend from the lower surface 204 of the swivel hub 200 to the handle portion 320 only along the first side 114 of the support rod 110. In some embodiments, the upper portion 310 can be omitted, such that the handle portion 320 can be directly connected to the swivel hub 200. In some embodiments, the upper portion 310 can extend completely around the support rod 110.

[0033] The handle portion 320 can provide a structure that allows a user to manually engage the hub controller 300 to move the umbrella assembly 100 between an open state and a closed state. In addition, the handle portion 320 can also provide a structure for accommodating a locking mechanism 330. As Figure 3 and Figure 4 shown, the handle portion 320 can include a housing 324 and a hole 322. The handle portion 320 can extend from the upper portion 310 on the first side 114 of the support rod 110 to the opposite second side 115 of the support rod 110. The handle portion 320 can extend away from the second side 115 of the support rod 110 substantially perpendicular to the longitudinal axis A1 of the support rod 110. At least one of the top and bottom surfaces of the handle portion 320 extending from the first side 114 to the second side 115 can be inclined downward. The hole 322 can be perpendicular or parallel to the longitudinal axis A1 of the support rod 110. An acute angle can be formed between at least one of the top and bottom surfaces of the handle portion 320 and the hole 322.

[0034] The housing 324 can define an inner surface 325 that extends within the handle portion 320. The housing 324 can be sized to accommodate the locking mechanism 330. Additionally, the housing 324 can also define a slot 326 that is sized to receive the actuator 332 and allow the actuator 332 to translate axially within the housing 324. The slot 326 can include a support surface 327 and opposing inner surfaces 328. The support surface 327 and the inner surfaces 328 can be part of the inner surface 325. The handle portion 320 can include a hole 322 for receiving a user's hand. The hole 322 can form a passage that extends completely or partially through the handle portion 320. The housing 324 can be disposed around the hole 322. The hole 322 can intersect the housing 324 such that the housing 324 and the hole 322 form a continuous cavity. The outer surface 345 of the handle portion 320 can be configured to allow a user to insert fingers into the top opening of the hole 322 while wrapping a thumb around the handle portion 320 and inserting it into the bottom opening of the hole 322, thereby gripping the handle portion 320. Thus, the handle portion 320 can be used as an ergonomic grip that enables the user to easily move the lower hub assembly 150 between upper and lower positions on the support rod 110. It should be understood that, Figure 3 and Figure 4 the handle portion 320 shown is not the only possible form. In other embodiments, the handle portion 320 can take any form suitable for a user to manually engage the hub controller 300.

[0035] As Figure 3 and Figure 4 shown, the hub controller 300 can include a locking mechanism 330 for engaging with the locking fixture 116 and locking the runner hub 200 in a specific position along the support rod 110. The locking mechanism 330 can be coupled to or mounted within the handle portion 320. The locking mechanism 330 can include an actuator 332, a locking device 334, and one or more springs 350. At least a portion of the locking mechanism 330 can move within the housing 324, such as laterally, and in some cases perpendicular to the longitudinal axis A1 of the support rod 110. At least a portion of the locking mechanism 330 can move horizontally within the housing 324. An acute angle can be formed between at least one of the top and bottom surfaces of the handle portion 320 and the direction of movement of the locking mechanism 330.

[0036] Figures 5A - 5C Various views of the actuator 332 with the locking device 334 are described. Figure 5A A perspective view of the actuator 332 is described. Figure 5B A front view of the actuator 332 is described. Figure 5C is a side view of the actuator 332. The actuator 332 can be used as a trigger to bring the locking device 334 into contact with or out of contact with the locking fixture 116. AsFigures 5A - 5C As shown, the actuator 332 may include a generally annular or ring-shaped body 342. The actuator 332 may include an upper surface 347, a lower surface 346, two side surfaces 345, a front surface 348, and a rear surface 349. The actuator 332 may have a central opening 344 extending through the upper surface 347 and the bottom surface 346. The central opening 344 may be used to receive the fingers of the user's hand. The portion of the outer surface of the actuator 332 adjacent to the central opening 344 may form a gripping surface 336. As Figure 3 As shown, the actuator 332 may be mounted within the hole 322 and the housing 324 of the handle portion 320. When the actuator 332 is located within the handle portion 320, the central opening 344 of the actuator 332 may be at least partially aligned with the hole 322 of the handle portion 320. After the central opening 344 is aligned with the opening 322, the user may insert a finger into the opening 322, then into the central opening 344, and finally around the gripping surface 336 of the actuator 332.

[0037] The actuator 332 may be movable relative to the handle portion 320 between a first position and a second position. The actuator 332 may be movable between the first position and the second position in response to a force applied by the user's hand to the gripping surface 336. The actuator 332 may translate within a slot 326 provided within the housing 324 of the handle portion 320. The actuator 332 may translate along a movement axis A2 that is generally perpendicular to the longitudinal axis A1 of the support rod 110. In certain embodiments, the actuator may be configured to move only in one direction of movement. Additionally, in certain embodiments, the actuator may be configured to move between the first position and the second position without radial movement, i.e., without rotating about a pivot point. This restricted movement reduces the complexity of the connection of the actuator 332 to the handle portion 320.

[0038] The actuator 332 may have a depth from its rear surface 349 to its front surface 348, a width from one side surface 345 to the other side surface 345, and a height from its upper surface 347 to its bottom surface 346. In Figures 5A - 5CIn the illustrated embodiment, the actuator 332 is generally annular in shape, with a width greater than its depth. Additionally, the actuator 332 has a generally oval central opening 344. In other embodiments, the actuator 332 and the central opening 344 can have any shape, such as square, T-shaped, Y-shaped, or other shapes that allow a finger to grasp the lateral portion. In certain embodiments, the actuator 332 can have a shape that does not form a central opening 344. In certain embodiments, the actuator 332 can be formed in any shape, with a first portion extending away from the support rod 110 along the depth of the actuator 332 and a second portion extending along the width of the actuator 332. In other embodiments, the actuator 332 can have any shape suitable as a trigger to engage or disengage the locking device 334 with the locking clamp 116.

[0039] The actuator 332 can include one or more sliders 340. The function of the sliders 340 is to facilitate smooth axial movement of the actuator 332 within the handle portion 320. Specifically, the sliders 340 provide a raised contact surface to reduce friction between the actuator 332 and the inner surface 325 of the handle portion 320. One or more sliders 340 can facilitate translation of the actuator 332 within the handle portion 320 without causing planar contact between the actuator 332 and the inner surface 325 of the handle portion 320. Additionally, the sliders 340 can also be spacers that serve to separate the actuator 332 from the inner surface 325 of the handle portion 320. When used as spacers, the sliders 340 can prevent the actuator 332 from wobbling or misaligning within the housing 324 of the handle portion 320. During operation of the locking mechanism 330, one or more or all of the sliders 340 can be in contact with or not in contact with the inner surface 325 of the handle portion 320. One or more sliders 340 can be provided on one or more of the upper surface 347, bottom surface 346, or two side surfaces 345 of the actuator 332. As Figures 5A - 5CAs shown, the slider 340 may include ridges or elongated protrusions extending along the outer surface of the actuator 332. Each slider may be disposed on the actuator 332 such that the length of the slider is parallel to the direction of movement of the actuator 332. In the illustrated embodiment, the slider 340 is configured to extend along the width of the actuator 332. In the illustrated embodiment, the actuator 332 includes nine sliders 340 disposed on the outer surface. Two sliders 340 are located on the upper surface 347 of the actuator 332. The two top sliders 340 are disposed at opposite ends of the upper surface 347 such that each top slider is adjacent to a respective side surface 345. Three sliders 340 are located on the lower surface 346. Two bottom sliders 340 are disposed at opposite ends of the bottom surface 346 such that each bottom slider is adjacent to one of the respective side surfaces 345. The third bottom slider is disposed along the midline of the actuator 332 and is located between the other two sliders 340. The bottom sliders 340 may extend from the bottom surface 346 of the actuator 332 to the support surface 327 of the handle portion 320. Four sliders 340 are disposed on the two side surfaces 345, two sliders 340 on each side surface 345. The two sliders 340 disposed on each side surface 345 are disposed in a spaced relationship along each side surface 345 such that one slider 340 is disposed adjacent to the upper surface 347 of the actuator 332 and the other slider 340 is disposed adjacent to the bottom surface 346. The side sliders 340 may extend from the side surface 345 of the actuator 332 to the inner surface 328 of the handle portion 320. In the illustrated embodiment, the slider 340 is an integral protrusion extending from the actuator 332. In other embodiments, the slider 340 may be a separate component fixed to the actuator 332. Alternatively, the slider 340 may extend from or be connected to the inner surface 325 of the handle portion 320 rather than the actuator 332. In other embodiments, the number of sliders 340 may be zero, one, two, or any other number. Additionally, the slider 340 may be formed in any suitable shape and may be disposed at any location on the actuator 332 or the handle portion 320.

[0040] The actuator 332 may include a locking device 334. The function of the locking device 334 is to engage with the locking fixture 116 to lock the lower hub assembly 150 in a specific position along the support rod 110. The locking device 334 may include any protrusion, pin, hole, groove, flange, ring, engaging member, step, ratchet, or any other structure for engaging with the corresponding locking fixture 116. As Figure 5AAs shown, the locking device 334 may include a protrusion having two teeth 338. The two teeth 338 may be sized to match the spaced grooves 118 of the locking fixture 116. In the illustrated embodiment, the teeth 338 of the locking device 334 include an upwardly facing bevel and a horizontal surface that faces downward and away from the bevel. When the locking device 334 engages with the locking fixture 116, the locking device 334 may be configured to interlock with the locking fixture 116. Specifically, the two teeth 338 may be disposed in two spaced grooves 118 of the locking fixture 116 such that the horizontal surfaces of the teeth 338 of the locking device 334 rest against the corresponding horizontal surfaces of the teeth of the locking fixture 116. When the locking device 334 engages with the locking fixture 116, the lower hub assembly 150 may be supported in an upper position by vertically loading the locking device 334 onto the locking fixture 116. By providing multiple teeth 334, such as two, three, four or more teeth, the load on each tooth can be reduced, thereby allowing for smaller teeth or a more flexible choice of the material for the teeth. In some embodiments, a single tooth 334 may be sufficient. Thus, the lower hub assembly 150 may be held in an upper position without friction engagement, thereby avoiding sliding along a vertical surface. The two teeth 338 may be disposed in any one or more of the multiple spaced grooves 118 to position the lower hub assembly 150 in one of multiple positions along the locking fixture 116. As Figure 5A shown, the locking device 334 may be coupled to and project from the rear surface of the actuator 332. As Figure 4 shown, the locking device 334 may be a separately manufactured component that is fixed to the actuator 332. In other embodiments, the locking device 334 is integrally formed with the actuator 332.

[0041] As Figure 5AAs shown, the actuator 332 may include a thickened portion 335. The thickened portion 335 may be sized to accommodate the locking device 334. The thickened portion 335 may include a raised surface extending from the upper surface 347 of the actuator 332 and a raised surface extending from the rear surface 349 of the actuator 332. The raised surfaces may be generally rectangular. The raised surface extending from the upper surface 349 of the actuator 332 may extend above the slider 340 on the upper surface 347. If the actuator 332 extends from the upper surface 349 of the thickened portion 335 above the slider 340 on the upper surface 347, then if the actuator 332 is tilted or rotated within the housing 324 about the upper surface 349, the slider will be the first point of contact. In other embodiments, the raised surface extending from the upper surface 349 may extend to the same height as or below the height of the slider 340 on the upper surface 347 of the actuator 332. The housing 324 of the handle portion 320 may include a cutout sized to receive the thickened portion 335 when the actuator 332 is moved to the first position. The cutout may serve as a guide for the thickened portion 335.

[0042] The locking mechanism 330 may further include one or more springs 350 for biasing the actuator 332 in the direction of the rod. For example, a helical spring 350 may be disposed between the front surface of the actuator 332 and the inner surface 325 of the handle portion 320. The actuator 332 may include one or more spring slots 352 sized to receive the spring 350. The spring slots 352 may be configured as blind grooves on the surface of the actuator 332. The spring slots 352 serve to maintain a secure coupling of the spring 350 to the actuator 332. As Figures 5A - 5B shown, the actuator 332 may include two spring slots 352 disposed along the front surface of the actuator 332. Two springs 350 may be inserted into each spring slot 352. In a default position where no force is applied to the actuator 332 by the user, one or more springs 350 exert a resistance on the actuator 332, biasing the actuator 332 toward the support rod 110. If the locking device 334 is aligned with the locking fixture 116, the spring 350 will maintain the locking device 334 in engagement with the locking fixture 116. The spring 350 may be compressed by applying a force to the actuator 332, causing the actuator 332 to move away from the support rod 110. In other embodiments, the helical spring 350 may be replaced by any other suitable device that provides resistance. For example, a torsion spring, leaf spring, strap, or similar device may be used in place of the helical spring 350.

[0043] As Figure 3As shown, the lower hub assembly 150 may further include one or more rollers. The function of the rollers is to facilitate the smooth movement of the lower hub assembly 150 along the support rod 110. When the lower hub assembly 150 translates axially along the support rod 110, the rollers contact the support rod 110 and roll along the outer surface of the support rod 110. As Figure 3 shown, the lower hub assembly 150 may include four rollers. Specifically, the first roller 360 and the second roller 362 may be connected to the runner hub 200, and the third roller 364 and the fourth roller 366 may be connected to the hub controller 300. The first roller 360 may be connected to the runner hub 200 at a position in contact with the first side 114 of the support rod 110, and the second roller 362 may be connected to the runner hub 200 at a position in contact with the opposite second side 115 of the support rod 110. Similarly, the third roller 364 may be connected to the hub controller 300 at a position in contact with the first side 114 of the support rod 110, and the fourth roller 366 may be connected to the hub controller 300 at a position in contact with the opposite second side 115 of the support rod 110. The first roller 360 and the third roller 364 may be aligned with each other to contact the substantially same first side 114 of the support rod 110. The second roller 362 and the fourth roller 366 may be aligned with each other to contact the substantially same second side 115 of the support rod 110. The function of the rollers is to guide the axial movement of the lower hub assembly 150 along the support rod 110 to prevent the lower hub assembly 150 from overlapping when moving axially along the support rod 110. In the illustrated embodiment, the rollers substantially form the shape of a cylindrical dog bone. Specifically, the diameter of each roller gradually decreases from the maximum diameter at both ends to the minimum diameter at the middle section. The concave shape of the rollers can match the convex contour of the outer surface of the cylindrical support rod 110. In other embodiments, the rollers may have any other suitable shape. For example, in other embodiments, the rollers may be spheres or cylinders with a substantially constant diameter. In addition, Figure 3 the roller positions shown are not the only possible positions. Specifically, any one of the rollers can be positioned to contact any side of the support rod 110. In addition, any one of the rollers can be connected to the runner hub 200 or the hub controller 300. In addition, other embodiments may also include zero, one, two, three, four or any other number of rollers.

[0044] The above components of the umbrella assembly 100 are preferably composed of relatively strong and lightweight materials that have suitable durability, abrasion resistance, and weather resistance. Suitable materials for one or more components of the umbrella assembly 100 may include, but are not limited to, light corrosion-resistant steel, aluminum alloy, titanium alloy, metal, wood, plastic, carbon fiber material, and / or other well-known relatively high-strength weather-resistant materials. In a particular application, the desired aesthetic characteristics of the umbrella assembly 100 may at least partially determine the appropriate selection of the structural materials of the umbrella assembly 100. For example, in some applications, the desired aesthetic characteristics of the umbrella assembly 100 may indicate that the components of the umbrella assembly 100 should use finished or unfinished wood, although other components may have certain advantages in terms of strength, weight, cost, or other characteristics. Therefore, it can be understood that in different applications, the materials used to manufacture the umbrella assembly 100 will vary, and given the disclosure and description of the subject application and the requirements of the particular application, it will be obvious to those of ordinary skill in the art to select the appropriate materials.

[0045] Figures 6A - 6C Describes different positions of the lower hub assembly 150 when the umbrella assembly 100 moves between the open state and the closed state. As described above, the umbrella assembly 100 can move between the open state and the closed state by moving the lower hub assembly 150 along the support rod 110 between the upper position and the lower position. The lower hub assembly 150 can be fixed in the upper position by the engagement of the locking mechanism 330 with the locking fixture 116 on the support rod 110. By moving the actuator 332 between the first position and the second position, the locking mechanism 330 can be engaged with or disengaged from the locking fixture 116.

[0046] Figure 6A Describes a cross-sectional view when the lower hub assembly 150 is fixed in the upper position. In the upper position, the lower hub assembly 150 is placed at a higher position along the support rod 110. Specifically, when the lower hub assembly 150 is placed above the locking fixture 116, it can be in the upper position. As Figure 6A shown, when the lower hub assembly 150 is in the upper position, the umbrella ribs 120 are substantially horizontally oriented, and the umbrella canopy 130 is sleeved therein to be extended. Fixing the lower hub assembly 150 in the upper position can keep the umbrella assembly 100 in the open state. The lower hub assembly 150 is fixed in the upper position by engaging the locking mechanism 330 with the locking fixture 116. By moving the actuator 332 to the first position, the locking mechanism 330 can be engaged with the locking fixture 116. When the actuator 332 is in the first position (as Figure 6AAs shown, the actuator 332 is disposed at the proximal end of the support rod 110 to engage the locking device 334 with the locking clamp 116. In the illustrated embodiment, the locking device 334 includes two teeth 338, and the locking clamp 116 includes a ratchet feature having spaced-apart grooves 118. When the actuator 332 in the illustrated embodiment is in the first position, the locking device 334 interlocks with the locking clamp 116 such that the two teeth 338 are disposed in the two spaced-apart grooves 118. As shown, the grooves 118 are formed in a separate component mounted in the vertical channel of the support rod 110. In an improved embodiment, the grooves 118 may be formed directly in the wall of the support rod 110. The teeth 338 may overlap in the vertical direction such that the horizontal surface of the locking clamp 116 is directly below the horizontal surface of each tooth of the teeth 336. This arrangement can be considered to provide direct support without the need for frictional forces acting vertically along the vertical clamping surface. This avoids compression cycles that may lead to accelerated wear. The actuator 332 may be held in the first position by one or more springs 350 disposed between the front surface of the actuator 332 and the inner surface 325 of the handle portion 320. The spring 350 exerts a resistance on the actuator 332, biasing it towards the support rod 110. When in the first position, the gripping surface 336 of the actuator 332 may extend into the hole 322 such that the hole 322 may be partially blocked by the gripping surface 336. When the actuator 332 is in the first position and the locking device 334 is engaged with the locking clamp 116, the lower hub assembly 150 is fixed in the upper position and prevented from translating axially up or down along the support rod 110. Thus, once the lower hub assembly 150 is positioned in the upper position and the locking mechanism 330 is engaged with the locking clamp 116 by moving the actuator 332 to the first position, the umbrella assembly 100 can be held in the open position without further input from the user.

[0047] Figure 6B A cross-sectional view of the lower hub assembly 150 is described, which is still in the upper position, but the locking mechanism 330 is disengaged from the locking clamp 116. As Figure 6BAs shown, by moving the actuator 332 to the second position, the locking mechanism 330 can be disengaged from the locking fixture 116. By overcoming the resistance of the spring 350, the actuator 332 can move in the slot 326 in a direction away from the support rod 110, thus moving to the second position. Relative to its position in the first position, when the actuator 332 is in the second position, the actuator 332 is located at the distal end of the support rod 110, so that the locking device 334 does not engage with the locking fixture 116. As shown in the illustrated embodiment, when the actuator 332 is in the second position, the two teeth 338 of the locking device 334 are not located in any of the spaced grooves 118 of the locking fixture 116. In addition, when the actuator 332 is in the second position, the spring 350 is compressed to a compressed state. In the second position, the clamping surface 336 of the actuator 332 can be disposed within the housing 324 of the handle portion 320, such that the clamping surface no longer blocks the hole 322. In order to hold the actuator 332 in the second position, a continuous force must be applied to the actuator 332 to prevent the spring 350 from pushing the actuator 332 back to the first position. Thus, when the locking mechanism is disengaged from the locking fixture 116 by moving the actuator 332 to the second position, the lower hub assembly 150 can freely move up or down on the support rod 110 without being obstructed by the locking fixture 116.

[0048] Figure 6C A cross-sectional view of the lower hub assembly 150 in the lower position is described. In the lower position, the lower hub assembly 150 is located a sufficient distance below the locking fixture 116 to cause the umbrella ribs 120 to have a substantially vertical orientation. When the umbrella ribs 120 are substantially in the vertical orientation, the umbrella assembly 100 is folded into a closed state. When the lower hub assembly 150 is in the lower position, the actuator 332 can move to the first position without engaging with the locking fixture 116. If the support rod 110 includes an elongate groove, when the actuator 332 is in the first position, the locking device 334 can project into the elongate groove.

[0049] During operation, the user can manually move the umbrella assembly 100 between an open state and a closed state using the hub controller 300. The user can hold the handle portion 320 of the hub controller 300 and place a finger in contact with the gripping surface 336 of the actuator 332. The user can squeeze the gripping surface 336 with a hand to move the gripping surface 336 away from the support rod 110 and into the housing 324 of the handle portion 320, thereby moving the actuator 332 from the first position to the second position. The user can hold the actuator 332 in the second position by continuously applying a downward or deflecting force to the gripping surface 336 of the actuator 332. The user can release the hand and relieve the pressure on the gripping surface 336 of the actuator 332, thereby returning the actuator 332 to the first position. Once the actuator 332 is released, the spring 350 will push the actuator 332 back to the first position. Compared with a clamping mechanism that typically requires rotating a threaded knob to apply a clamping force in the vertical direction, the embodiments disclosed in this technical solution are easier to use. Compared with a handle that requires hinging the handle around a pivot point and then vertically translating the handle, the embodiments disclosed in this technical solution are easier to use because after moving the actuator 332, the user tightly holds the lower portion of the hub controller 300, thus being in an ergonomic position to move the umbrella assembly 100.

[0050] If the user wishes to move the umbrella assembly 100 from the closed state to the open state, the following steps can be performed: (1) Hold the handle portion 320 with a hand, (2) Apply a deflecting force on the gripping surface 336 to move the actuator 332 from the first position to the second position, (3) Hold the actuator 332 in the second position and apply an upward force to the lower hub assembly 150 to lift the lower hub assembly 150 from the lower position to the upper position, (4) Align the locking mechanism 330 with the locking fixture 116 and release the gripping surface 336 to return the actuator 332 to the first position surface, so that the locking mechanism 330 engages with the locking fixture 116. If the user wishes to move the umbrella assembly 100 from the open state to the closed state, the following steps can be performed: (1) Hold the handle portion 320 with a hand, (2) Apply a deflecting force on the gripping surface 336 to move the actuator 332 from the first position to the second position to disengage the locking mechanism 330 from the locking fixture 116, (3) Hold the actuator 332 in the second position and apply a downward force to the lower hub assembly 150 to lower the lower hub assembly 150 from the upper position to the lower position below the locking fixture 116, (4) Release the gripping surface 336.
