Description

Technical Field

[0001] The invention relates to an umbrella, in particular to a tube umbrella which can be folded inwards and retracted into a tube body as a whole. The umbrella can be used as a daily umbrella or as a sun umbrella for gardens. Background Art

[0002] When a wet umbrella is brought into a public transport during rush hour, the rain-soaked surface of the umbrella comes into contact with the clothing, such as pants and skirts, of surrounding passengers in the public transport, often wetting their clothing and causing annoyance to these passengers. When a new rain-soaked umbrella is placed in an umbrella stand, it can wet other umbrellas that were previously placed in adjacent stands. When an umbrella from an umbrella stand adjacent to the wet umbrella is removed, the wet surface of the umbrella can wet the user's hands and clothing, causing discomfort to the user. Furthermore, when a person closes their umbrella and boards a public transport on a rainy day, a large number of raindrops spread onto their hands or wet the floor and seats of the vehicle. Similarly, when the person opens their umbrella after getting off the vehicle, raindrops inevitably fall onto their hands.

[0003] So far, people have been looking for an umbrella with wet umbrella cloth that is not exposed to the outside to eliminate this inconvenience. The State Intellectual Property Office of China has published an umbrella CN100389698, which discloses a shaft with a metal ferrule at one end and a handle at the other end, and a wheel mounted on the shaft and capable of sliding. The wheel is provided with a plurality of elastic support ribs. The invention discloses an inward-folding umbrella, in which the umbrella cloth is folded inward, effectively preventing raindrops on the umbrella cloth from scattering outward. However, there is still a problem. After folding, in order to facilitate taking, if the handle is taken, the umbrella must be in an inverted state, and the water on the umbrella cloth will still slide down the umbrella cloth and drip onto the floor of public transportation. Since the umbrella cloth is folded inward, During the folding process, the water on the umbrella cloth cannot be drained out, and a large amount of rainwater accumulates on the surface of the umbrella cloth, which can easily form a large area of rainwater on the floor of the car, making it easy to slip. Or, in order to avoid rainwater dripping, people hold the umbrella in the middle or upper part, and the umbrella is placed vertically. The ends of the umbrella are in a relatively free and loose state. The raindrops on the umbrella cloth may still fall and wet the seats or clothes. Summary of the Invention

[0004] In response to the shortcomings of the prior art, the present invention designs a tube umbrella, which has a structure that eliminates the need to worry about raindrops on the umbrella cloth spreading. The inward-folded umbrella cloth is supported by a tube body, and after folding, the umbrella cloth is completely retracted into the tube body. As long as the tube body is not inverted, there is no possibility of water droplets on the umbrella cloth spreading. Furthermore, the first sliding part and the second sliding part of the present invention slide in the tube body. When the umbrella is opened, only the umbrella cloth supporting end of the first sliding part is higher than the tube body, and the first sliding part and the second sliding part as a whole are still located in the tube body, that is, the tube body is the support column of the entire umbrella, which increases the strength of the umbrella and meets the needs of certain harsh usage environments. Furthermore, the first sliding part and the second sliding part, as well as the umbrella ribs and the support assembly, form a stable triangular structural design. The structure of the umbrella is stable after opening, and the wind resistance is increased.

[0005] The technical solutions of the present invention are as follows:

[0006] The cylindrical umbrella comprises a hollow cylindrical body with an open top, and is characterized in that:

[0007] a first sliding portion, which is disposed inside the cylindrical body and can slide up and down along the inner wall of the cylindrical body, and one end of each of the plurality of ribs is rotatably connected to the first sliding portion;

[0008] a second sliding portion, the second sliding portion being arranged inside the cylindrical body and sleeved on the first sliding portion, and the first sliding portion being provided with a limiting member for limiting the position of the second sliding portion; one end of the supporting member being rotatably connected to the second sliding portion, and the other end of the supporting member being slidably connected to the umbrella rib;

[0009] a sliding component, which is arranged outside the cylinder and connected to the second sliding part to drive the second sliding part to move in the cylinder;

[0010] A guide groove corresponding to the support component is provided at the upper end of the cylinder. When the umbrella is opened, the support component will expand outwards in the guide groove.

[0011] An umbrella cloth, the center of the umbrella cloth is connected to the upper end of the first sliding part, and the four sides of the umbrella cloth are connected to the ends of the umbrella ribs. After the umbrella is folded, the umbrella ribs and the ribs are folded in the cylinder, and there is no problem of water droplets spilling and dripping on the umbrella cloth. During the opening of the umbrella, the supporting component is folded outward in the guide groove, and finally the umbrella ribs lean against the upper end of the cylinder. The first sliding part and the second sliding part are located in the cylinder, that is, the cylinder is used to support the umbrella after opening, thereby improving the overall strength of the umbrella and having better windproof performance.

[0012] Furthermore, it also includes a first elastic part, which is sleeved on the first sliding part, and its two ends are respectively against the upper end surfaces of the first sliding part and the second sliding part; and a second elastic part, which is also sleeved on the first sliding part, and its two ends are respectively against the lower end surface of the second sliding part and the limiting component, and the elastic force of the second elastic part is greater than the elastic force of the first elastic part. Through the cooperation between the first elastic part, the second elastic part, the first sliding part and the second sliding part, the umbrella is self-locked after opening, and the second sliding part will not slide down.

[0013] Furthermore, the first sliding part is provided with a through hole corresponding to the umbrella rib, and the second sliding part is provided with a push rod corresponding to the through hole. The push rod passes through the through hole and acts on one end of the umbrella rib. Here, the push rod on the second sliding part passes through the through hole of the first sliding part to push the end of the umbrella rib, so that during the opening process of the umbrella, there is a force acting on the umbrella rib, which prompts the umbrella rib to open and reduces the resistance when the umbrella is opened.

[0014] Furthermore, a top spring is sleeved on the top rod, and the top spring is a spring sleeved on the top rod. During the rising process of the second sliding part, the top rod is prevented from hard contact with the umbrella ribs, providing a buffer.

[0015] A spring sheet is provided on the surface of the connection between the umbrella rib and the first sliding part, and a bending area is formed on the surface of the spring sheet. When the umbrella is opened, the horizontal part of the bending area of the spring sheet presses against the upper end surface of the connection between the umbrella rib and the first sliding part, and the inclined part of the bending area abuts against the side of the connection between the umbrella rib and the first sliding part. The spring sheet and the connection between the umbrella rib and the first sliding part form an elastic fit. When the folding force applied to the umbrella rib is less than the deformation force of the spring sheet, the spring sheet cannot pass over the connection between the umbrella rib and the first sliding part, which also increases the wind resistance of the umbrella to a certain extent.

[0016] Furthermore, the umbrella ribs are hollow tubes, one end of the ribs is connected to the first sliding part by a pin, and the ribs are provided with a receiving assembly for receiving the supporting components along the length direction, and the other end of the ribs is provided with a sealing cover. The ribs are hollow tubes, which facilitates the control of the overall weight of the umbrella and ensures the lightweight characteristics of the umbrella. Furthermore, the receiving assembly is provided to provide a storage space for the supporting assembly after the umbrella is folded, so that the width of the umbrella is reduced after folding.

[0017] Furthermore, the surface where the first sliding part and the second sliding part contact the cylinder is provided with a concave accommodating area, and a rolling component in the accommodating area reduces the sliding resistance of the first sliding part and the second sliding part. The provided rolling component converts the sliding friction between the first sliding part, the second sliding part and the cylinder into rolling friction, thereby reducing the friction between the first sliding part, the second sliding part and the cylinder, reducing the force required to open the umbrella, and being more suitable for different people.

[0018] The first sliding part includes a first sliding plate, a support shaft is provided on the axis of the first sliding plate, an umbrella cloth fixing cap is provided on the upper end of the support shaft, and mounting columns for connecting the ends of the umbrella ribs are uniformly distributed on the surface of the first sliding plate.

[0019] The second sliding part includes a second sliding plate, the axis of which is provided with a sliding sleeve that cooperates with the first sliding part, and the upper surface of the second sliding plate is uniformly provided with support mounting columns for connecting the ends of the support components.

[0020] The above two make further specific limitations on the structures of the first sliding part and the second sliding part. The use of a disc-shaped, support shaft, and sliding sleeve structure is beneficial to product quality control and meets the requirements of lightweight.

[0021] Furthermore, the lower surface of the second sliding plate extends downward along the edge to form an anti-tilt auxiliary ring. When the second sliding plate tends to flip over, the lower end of the auxiliary ring will abut against the inner wall of the cylinder, avoiding structural damage to the umbrella in bad weather.

[0022] Furthermore, a handle assembly made of plastic or metal is provided at the lower end of the cylinder 1 .

[0023] Furthermore, the handle assembly is a hollow pipe with an upper end connected to the lower end of the cylinder and an open lower end, and the anti-wolf device is installed in the hollow pipe.

[0024] Furthermore, a hook assembly is provided at the lower end of the handle assembly, and the hook assembly includes a connecting end cap connected to the handle assembly, and also includes an open arc-shaped hook, a connecting column is formed at one end of the hook, and a step hole is provided on the connecting end cap, the connecting column is inserted into the step hole, and is connected to the connecting column by a screw for limiting, and a tensioning spring is provided on the connecting column, and the two ends of the tensioning spring are respectively abutted against the surface of the end cap of the screw and the step surface, and a limiting assembly is provided between the connecting end cap and the hook, and the limiting assembly includes a groove or ridge provided on the connecting end cap, and a ridge or groove provided on the hook.

[0025] The present invention has the following advantages:

[0026] 1. The present invention designs a tube umbrella, which has a structure that eliminates the worry about raindrops on the umbrella cloth spreading. The umbrella cloth folded inward is supported by a tube body, and after folding, the umbrella cloth is completely retracted into the tube body. As long as the tube body is not inverted, there is no possibility of water droplets on the umbrella cloth spreading.

[0027] 2. The first sliding portion and the second sliding portion of the present invention slide within the cylinder. When the umbrella is opened, only the cloth support end of the first sliding portion is higher than the cylinder, and the first and second sliding portions as a whole remain within the cylinder. That is, the cylinder serves as the support column for the entire umbrella, thereby increasing the strength of the umbrella and meeting the requirements of certain harsh operating environments.

[0028] 3. The first sliding part and the second sliding part, as well as the umbrella ribs and the supporting assembly of the present invention form a stable triangular structural design. The structure of the umbrella is stable after opening, and the wind resistance is increased. Furthermore, the first elastic component and the second elastic component are provided to push the second sliding part to move on the first sliding part and fix the relative position of the second sliding part on the first sliding part, thereby achieving self-locking after the umbrella is opened, and the second sliding part will not slide down.

[0029] 4. The present invention can be used as both an everyday umbrella and a garden parasol, requiring only the enhancement of various components depending on the specific use scenario. Whether used as an everyday umbrella or a garden parasol, during the opening process, the ribs move forward and finally spread out to complete the final opening. Throughout the entire opening process, before the umbrella fabric unfolds, the first sliding portion, the second sliding portion, and the ribs all move forward, eliminating the need for lateral mechanical deployment, thereby enhancing the safety of the umbrella during opening.

DETAILED DESCRIPTION

[0050] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] like Figures 1 to 3 As shown, the cylindrical umbrella comprises a hollow cylindrical body 1 with an upper end opening, characterized in that:

[0052] a first sliding portion 2, which is disposed inside the cylinder and can slide up and down along the inner wall of the cylinder, and one end of a plurality of ribs 3 is rotatably connected to the first sliding portion;

[0053] A second sliding portion 4 is disposed within the cylindrical body and is sleeved on the first sliding portion. That is, in this embodiment, the second sliding portion can slide up and down on the first sliding portion, and the first sliding portion is provided with a limiting member 5 for limiting the position of the second sliding portion; one end of a supporting member 6 is rotatably connected to the second sliding portion, and the other end of the supporting member 6 is slidably connected to the umbrella rib 3; the limiting member described here is a nut threadedly connected to the first sliding portion or a disc member connected in another detachable manner; the supporting member is a pipe fitting that supports the umbrella ribs when the umbrella is in the open state;

[0054] a sliding member 7, which is disposed outside the cylinder and connected to the second sliding portion to drive the second sliding portion to move within the cylinder;

[0055] The upper end of the cylinder 1 is provided with a guide groove 10 corresponding to the support member. During the opening process of the umbrella, the support member will expand outward in the guide groove. Furthermore, the upper end of the guide groove is provided with a recess 101 which is directly equal to or slightly larger than the umbrella rib. Figure 4 and Figure 5 When the umbrella is fully opened, the ribs can be embedded in the recesses, which can limit the circumferential position of the ribs and prevent deformation of the supporting components during the rotation of the umbrella. Furthermore, the height of the first sliding portion exposed from the cylinder is further reduced, shortening the overall length of the umbrella.

[0056] An umbrella cloth 12, the center of which is connected to the upper end of the first sliding part, and the periphery of which is connected to the ends of the umbrella ribs.

[0057] The user pushes the sliding component located outside the cylinder to move upward, and the movement of the sliding component drives the second sliding part to move upward inside the cylinder. Since the second sliding part is sleeved on the first sliding component, the second sliding component also drives the first sliding part to move upward inside the cylinder, so that the entire umbrella ribs, umbrella cloth and support assembly move as a whole toward the upper part of the cylinder. Since the umbrella ribs and the support component are restricted by the cylinder, the umbrella ribs will not spread out during the upward movement. When the connection between the support component and the second sliding part moves to the bottom of the guide groove, the cylinder can no longer restrict the support component. The connection between the ribs and the first sliding part is higher than the edge of the cylinder, and the ribs spread out to the four sides, and the entire umbrella body is fully opened. After opening, the supporting component is located in the guide groove, and the provided guide groove can limit the supporting component. After the umbrella is folded, the ribs and the ribs are folded in the cylinder, and there is no problem of water droplets spilling and dripping on the umbrella cloth. During the opening of the umbrella, the supporting component is folded outward in the guide groove, and finally the ribs lean against the upper end of the cylinder. The first sliding part and the second sliding part are located in the cylinder, that is, the cylinder is used to support the umbrella after opening, thereby improving the overall strength of the umbrella and having better windproof performance.

[0058] Furthermore, the sliding component 7 is a sliding sleeve arranged on the outside of the cylinder, and the sliding sleeve is arranged on the outer periphery of the cylinder. A strong magnetic connection is adopted between the sliding sleeve and the second sliding part. The movement of the sliding sleeve drives the second sliding part to move in the cylinder through magnetism. At this time, there is no need to open a notch on the surface of the cylinder, which is beneficial to the overall aesthetics of the cylinder; or, a sliding groove is provided on the surface of the cylinder, and the sliding sleeve is connected to the second sliding part through the sliding groove by a connecting member. The connecting member is a screw or rivet or other connection structure that can achieve a hard connection relationship. The aforementioned sliding component adopts a sliding sleeve arranged on the outside of the cylinder. When the sliding part is connected to the second sliding part by a hard connection, the structure of the sliding component can be a block or plate-shaped component suitable for pushing with a thumb, or an arc-shaped structure can be adopted.

[0059] Furthermore, the other end of the support component 6 is slidably connected to the umbrella rib 3, that is, the end of the support component 6 is connected to the umbrella rib and slides on the umbrella rib, and the two can undergo relative displacement of a short distance, which is mainly achieved in the following two ways: In the first way, a ball 60 is provided at the end of the support component 6, and the umbrella rib is a hollow rod. The ball 60 is arranged inside the umbrella rib, and a notch is provided on the umbrella rib 3 at the ball movement part, and the support component 6 is connected to the ball through the notch; in the second way, a sleeve 61 is provided at the end of the support component 6, and the sleeve 61 is sleeved on the umbrella rib and can slide on the umbrella rib 3, thereby realizing that the other end of the support component 6 is slidably connected to the umbrella rib, see for details. Figure 13 and Figure 14 .

[0060] Furthermore, it also includes a first elastic portion 9, which is sleeved on the first sliding portion 2, and the two ends of the first elastic portion 9 are respectively against the upper end surfaces of the first sliding portion 1 and the second sliding portion 4, and a second elastic portion 90, which is also sleeved on the first sliding portion 2, and the two ends of the second elastic portion 90 are respectively against the lower end surface of the second sliding portion 4 and the limiting component 5, and the elastic force of the second elastic portion 90 is greater than the elastic force of the first elastic portion 9. The first elastic portion and the second elastic portion are springs, and the first elastic portion and the second elastic portion are both in a compressed state. In the process of pushing the sliding component, due to the force of the person, the sliding component drives the second sliding portion to move upward, the first elastic portion is further compressed, and the second elastic portion is partially relaxed. The first sliding portion moves upward under the action of the force, and when the umbrella is opened to Figure 3 as well as Figure 10 In the state shown, at this time, the first sliding part and the second sliding part, the umbrella rib and the supporting part form a right triangle, as shown in the figure. At this time, the balance of the first sliding part, the second sliding part, the umbrella rib and the supporting part is relatively fragile and can be easily broken; when the human hand is separated from the sliding part, the external force disappears, and since the elastic force of the second elastic part is greater than the elastic force of the first elastic part, the second elastic part will push the second sliding part to move upward on the first sliding part for a distance, and finally the elastic forces of the first elastic part and the second elastic part reach a force balance. At this time, the first sliding part and the second sliding part, the umbrella rib and the supporting part form an obtuse triangle, as shown in the figure. Figure 11 As shown, when the umbrella cloth is subjected to external wind force, there will be an F branch on the support assembly. Since the support assembly is in an inclined state, the F branch can be decomposed into F branch 1 in the vertical direction and F branch 2 in the horizontal direction. That is, no matter what reverse force the umbrella cloth is subjected to, the support component will eventually generate a force to push the second sliding part to slide upward. At this time, through the cooperation between the first elastic component, the second elastic component, the first sliding part and the second sliding part, the self-locking of the umbrella after opening is achieved, and the second sliding part will not slide down. That is, the umbrella will not automatically retract under the action of external force in the open state, thereby ensuring the reliability of the umbrella.

[0061] Furthermore, the first sliding part 2 is provided with a through hole 20 corresponding to the umbrella rib, and the second sliding part 4 is provided with a push rod 40 corresponding to the through hole. The push rod 40 passes through the through hole 20 and acts on one end of the umbrella rib. Here, the push rod on the second sliding part passes through the through hole of the first sliding part to push the end of the umbrella rib, so that during the opening process of the umbrella, there is a force acting on the umbrella rib, which prompts the umbrella rib to open and increases the speed of opening the umbrella cloth.

[0062] Furthermore, a top spring 401 is sleeved on the top rod 40. The top spring 401 is a spring sleeved on the top rod. During the rising process of the second sliding part, the top rod is prevented from hard contact with the umbrella ribs, providing a buffer.

[0063] A spring sheet 30 is provided on the surface of the connection between the rib 3 and the first sliding part 2. The surface of the spring sheet forms a bending area. When the umbrella is opened, the horizontal part of the bending area 301 of the spring sheet presses against the upper end surface of the connection between the rib and the first sliding part, and the inclined part of the bending area abuts the side of the connection between the rib and the first sliding part. The spring sheet and the connection between the rib and the first sliding part form an elastic fit. When the folding force applied to the rib is less than the deformation force of the spring sheet, the spring sheet cannot pass over the connection between the rib and the first sliding part, which also increases the wind resistance of the umbrella to a certain extent.

[0064] Furthermore, the hollow tube of the umbrella rib 3 is connected to the first sliding part by a pin at one end of the umbrella rib, and a receiving assembly 31 for receiving the supporting component is provided along the length direction of the umbrella rib. The other end of the umbrella rib is provided with a sealing cover. The hollow tube of the umbrella rib is convenient for controlling the weight of the entire umbrella and ensuring the lightweight characteristics of the umbrella. Furthermore, the receiving assembly is used to provide a storage space for the supporting assembly after the umbrella is folded, so that the width of the umbrella after folding is reduced. Figure 8 and Figure 9 As shown, from Figure 8 As can be seen from the cross-sectional view of the umbrella ribs, there are notches on the surface of the umbrella ribs, which are used to accommodate components. When the umbrella is folded, the support components will be stored in the notches. Figure 9 From the cross-sectional view of the umbrella ribs, it can be seen that the surface of the umbrella ribs is provided with a concave arc or semi-circular arc shaped accommodation space. After the umbrella is folded, the supporting assembly is embedded in the accommodation space of the umbrella ribs. The accommodation area is formed by bending processing, which increases the strength of the umbrella ribs and further improves the wind resistance of the umbrella.

[0065] Further, see Figure 6 and Figure 7 The surfaces of the first sliding part 2 and the second sliding part 4 in contact with the cylinder are provided with a concave accommodating area 11, and a rolling component 110 is provided in the accommodating area to reduce the sliding resistance of the first sliding part and the second sliding part. The rolling component converts the sliding friction between the first sliding part, the second sliding part and the cylinder into rolling friction, thereby reducing the friction between the first sliding part, the second sliding part and the cylinder, and reducing the force required to open the umbrella, which can be better suitable for different people. In this embodiment, the rolling component uses steel balls, or a linear guide rail is provided inside the cylinder, and a sliding matching area that cooperates with the linear guide rail is provided on the first sliding part and the second sliding part.

[0066] See Figure 6The first sliding part 2 includes a first sliding plate 21, and a support shaft 22 is provided on the axis of the first sliding plate 21. The two ends of the support shaft are respectively located above and below the first sliding plate. The support shaft and the first sliding plate can be integrally formed or processed separately, and then the two are connected as a whole by a fixed method. An umbrella cloth fixing cap 23 is provided at the upper end of the support shaft 22, and the umbrella cloth fixing cap is connected to one end of the support shaft by a thread. The surface of the first sliding plate 21 is evenly provided with mounting posts 24 for connecting the ends of the umbrella ribs. The mounting posts are arranged perpendicular to the first sliding plate and are evenly distributed on the upper surface of the first sliding plate. In this embodiment, six mounting posts are provided on the upper surface of the first sliding plate, and the upper ends of the mounting posts are provided with pivot holes, and the ends of the umbrella ribs are rotatably connected to the holes.

[0067] See Figure 7 The second sliding part 4 includes a second sliding plate 43. A sliding sleeve 41 that cooperates with the first sliding part is provided on the axis of the second sliding plate 40. The sliding sleeve is sleeved on the support shaft of the first sliding part. The upper surface of the second sliding plate 40 is evenly distributed with support mounting columns 42 for connecting the ends of the support components. The support mounting columns are arranged perpendicular to the upper surface of the second sliding plate, and the upper ends of the support mounting columns are also provided with a pivot portion for connecting the support components.

[0068] The above two make further specific limitations on the structures of the first sliding part and the second sliding part. The use of a disc-shaped, support shaft, and sliding sleeve structure is beneficial to product quality control and meets the requirements of lightweight.

[0069] Furthermore, the lower surface of the second sliding plate is extended downward along the edge to form an anti-tilt auxiliary ring 44. When the second sliding plate tends to flip, the lower end of the auxiliary ring will abut against the inner wall of the cylinder to avoid structural damage to the umbrella in bad weather.

[0070] Furthermore, see Figure 15 The upper and lower ends of the cylinder 1 are open, and a plastic or metal handle assembly 8 is set at the lower end. According to actual usage requirements, the handle assembly can also be processed into a hollow shape. The handle assembly can be used to store some smaller items. The handle assembly can adopt a variety of shapes, such as a straight cylinder, a U-shape with long and short handles, etc., or a luminous body can be set on the handle assembly as a safety reminder signal at night to improve the safety of using an umbrella at night.

[0071] Furthermore, the handle assembly 8 is a hollow tube with the upper end connected to the lower end of the cylinder and the lower end open. The anti-wolf device 80 is installed in the hollow tube, and the anti-wolf device is added in the handle assembly. The anti-wolf device is an anti-wolf spray, an anti-wolf alarm, etc. In order to improve the usability of the anti-wolf device, a round hole is opened on the hollow tube, and the firing assembly of the anti-wolf device is exposed in the round hole, so that the user can trigger the anti-wolf device in time when receiving a threat. Furthermore, a nozzle for spraying spray can be opened on the hollow tube.

[0072] Furthermore, a hook assembly 81 is provided at the lower end of the handle assembly 8, and the hook assembly 81 includes a connecting end cap 810 connected to the handle assembly, and also includes an open arc-shaped hook 811. A connecting column 812 is formed at one end of the hook, and a hook connecting hole 813 is provided on the connecting end cap. The connecting column 812 is inserted into the hook connecting hole 813 and is connected to the connecting column by a screw 814 for limiting. The provided hook assembly enables the lower end of the tube umbrella to hang objects, freeing one hand of the user and improving ease of use.

[0073] like Figures 15 to 18 As shown, a hook assembly 81 is provided at the lower end of the handle assembly 8, and the hook assembly 81 includes a connecting end cap 810 connected to the handle assembly, and also includes an open arc-shaped hook 811, and a connecting column 812 is formed at one end of the hook 811, and a step hole 813 is provided on the connecting end cap.

The hook supports the cup body, freeing one hand of the user and improving the user experience.

[0074] The present invention has the following advantages:

[0075] 1. The present invention designs a tube umbrella, which has a structure that eliminates the worry about raindrops on the umbrella cloth spreading. The umbrella cloth folded inward is supported by a tube body, and after folding, the umbrella cloth is completely retracted into the tube body. As long as the tube body is not inverted, there is no possibility of water droplets on the umbrella cloth spreading.

[0076] 2. The first sliding portion and the second sliding portion of the present invention slide within the cylinder. When the umbrella is opened, only the cloth support end of the first sliding portion is higher than the cylinder, and the first and second sliding portions as a whole remain within the cylinder. That is, the cylinder serves as the support column for the entire umbrella, thereby increasing the strength of the umbrella and meeting the requirements of certain harsh operating environments.

[0077] 3. The first sliding part and the second sliding part, as well as the umbrella ribs and the supporting assembly of the present invention form a stable triangular structural design. The structure of the umbrella is stable after opening, and the wind resistance is increased. Furthermore, the first elastic component and the second elastic component are provided to push the second sliding part to move on the first sliding part and fix the relative position of the second sliding part on the first sliding part, thereby achieving self-locking after the umbrella is opened, and the second sliding part will not slide down.

[0078] 4. The present invention can be used as both an everyday umbrella and a garden parasol, requiring only the enhancement of various components depending on the specific use scenario. Whether used as an everyday umbrella or a garden parasol, during the opening process, the ribs move forward and finally spread out to complete the final opening. Throughout the entire opening process, before the umbrella fabric unfolds, the first sliding portion, the second sliding portion, and the ribs all move forward, eliminating the need for lateral mechanical deployment, thereby enhancing the safety of the umbrella during opening.
