Description

Technical Field

[0001] This invention relates to an outdoor sunshade device, specifically a sun umbrella that is easy for users to adjust in multiple directions. Background Technology

[0002] A parasol is a very common outdoor sunshade device. It mainly uses the umbrella frame to block the sun through the canopy, preventing users under the umbrella from being directly exposed to the sun and providing a shady outdoor gathering environment.

[0003] Chinese patent document CN115054038A discloses a sun umbrella with a double-column structure, which uses a downward-moving diagonal rod to raise and lower the umbrella frame assembly, and uses a crank to open and close the umbrella frame assembly. However, raising and lowering the sun umbrella and opening and closing it require two steps and operation of different parts, making it very inconvenient to use. Furthermore, the umbrella canopy is fixed to the columns, preventing the user from adjusting the canopy to suit the angle of sunlight.

[0004] Chinese patent document CN217827022U discloses an easily adjustable sun umbrella. It uses a handle that slides along a pillar, and an adjustable support structure is formed between the hinged diagonal rod, pull rod, and pillar to adjust the umbrella frame angle. The umbrella is then opened and closed by fixing the end cap and rotating the umbrella cords using a crank mechanism. While this sun umbrella allows adjustment of the canopy according to the angle of sunlight, its structure has two drawbacks. First, the umbrella fabric needs to block sunlight as much as possible, and its coverage area is generally large. However, the sun umbrella in the aforementioned patent document can only be fully opened after the angle adjustment or after the umbrella frame is adjusted to accommodate the umbrella area. Furthermore, the opened umbrella requires a second adjustment based on the actual angle of sunlight. Therefore, the angle adjustment steps for this structure are numerous, making it inconvenient for users to quickly open the umbrella to block sunlight. Second, the aforementioned patent document uses a combination of a crank mechanism and umbrella cords to open the umbrella. However, since sun umbrellas are generally used outdoors, the air contains a relatively high amount of dust and particles, which constantly adhere to the sun umbrella as they are blown by outdoor winds. The hand crank mechanism itself is small in size but has a large surface area, making it extremely easy to attract and accumulate dust or particles with high surface energy. Therefore, after prolonged use, the moving parts of the hand crank mechanism may accumulate dirt, become difficult to rotate, or even jam. Summary of the Invention

[0005] To address the shortcomings of existing sun umbrellas, this invention provides a flexible, easy-to-use, multi-directionally adjustable sun umbrella.

[0006] To achieve the aforementioned objectives, this invention provides a multi-directional adjustable sunshade, primarily comprising an umbrella frame, a support column, and a base. The upper and lower ends of the support column are connected to the umbrella frame and the base, respectively, while an umbrella fabric is fixedly covered on the umbrella frame, preventing direct sunlight from reaching the area under the support column. The umbrella frame mainly consists of an umbrella pole, a sliding assembly, and umbrella arm assemblies. The umbrella pole is movably connected to the upper end of the support column, the sliding assembly can move back and forth on the umbrella pole, and the umbrella arm assemblies are movably connected to both the sliding assembly and the umbrella pole. By utilizing the movement of the sliding assembly on the umbrella pole, the umbrella arm assemblies can be opened and closed, thereby enabling the opening and closing of the umbrella.

[0007] This application optimizes the above-mentioned structure. The umbrella arm assembly mainly includes a connecting arm and a transverse arm. The end of the umbrella pole away from the upright, the connecting arm, the transverse arm and the sliding assembly are connected together in a hinged manner to form a deformable polygonal structure in which the sliding assembly moves on the umbrella pole.

[0008] This application further refines the above structure. After the connecting arm and the transverse arm are hinged together, they form an angle with a fixed angle. The hinge point of the connecting arm and the transverse arm is located on the transverse arm outside the angle. When the sliding component moves to the end of the umbrella pole away from the column, the two ends of the transverse arm are subjected to forces in two different directions and retract quickly.

[0009] This application optimizes the above-mentioned structure. The sliding component includes a sliding seat and a set of rolling wheels. The set of rolling wheels is disposed on the sliding seat and is rolledly connected to two opposite planes of the umbrella shaft, so that the sliding component can move smoothly on the umbrella shaft.

[0010] This application further refines the above structure by providing at least two sliding seats along the axial direction of the umbrella pole. The lateral dimension of the sliding seats increases sequentially along the direction away from the upright of the umbrella pole, so that the umbrella fabric can be smoothly retracted when the sliding seats move towards the end of the umbrella pole away from the upright.

[0011] This application optimizes the above-mentioned structure by providing a first rotation adjustment mechanism between the umbrella pole and the upright. This first rotation adjustment mechanism can move up and down along the upright and can drive the umbrella pole to rotate around an axis, so that in addition to rotating the umbrella pole downwards for storage, the umbrella fabric can also be rotated along the umbrella pole to face the sunlight angle.

[0012] This application further refines the above structure. The first rotation adjustment mechanism includes a first base and a first turntable. The first base is movably connected to the column, and the first turntable is disposed on the first base and can rotate around an axis. The first turntable is coaxially arranged with the sliding assembly. The umbrella rod is hinged to the first turntable, with the hinge point located below the axis of the first turntable. The first base also has a first locking block, which can engage with the first turntable to prevent the first turntable from rotating.

[0013] This application further refines the above structure, adding a positioning block fixed to the column, which has a rotating shaft. A sliding component passes through the rotating shaft and can rotate around it, with the rotating shaft coaxial with the first turntable.

[0014] Furthermore, this application further optimizes the above-mentioned structure by adding a second rotation adjustment mechanism between the column and the base. This second rotation adjustment mechanism includes a second base and a second turntable, wherein the second base is fixedly mounted on the base, and the second turntable is disposed on the base and can rotate about an axis. The second turntable is fixed to the column so as to drive the column to rotate when it rotates. A second locking block is also provided on the second base, which can engage with the second turntable to prevent the second turntable from rotating.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the parasol of the present invention, a sliding assembly is provided on the upright to open or close the umbrella fabric, and the umbrella pole is movably connected to the upper end of the upright. On one hand, the umbrella arm assembly expands outward or retracts inward as the sliding assembly moves on the umbrella pole, causing the umbrella fabric fixed to the umbrella arm assembly to open or close accordingly. This structure not only makes the opening and closing of the parasol faster and smoother, but also makes the parasol suitable for use in situations where the opening distance is large. On the other hand, the movable connection between the umbrella pole and the upper end of the upright allows the umbrella pole to move freely on the upright to a certain extent. Users can adjust the tilt angle of the umbrella fabric according to the angle of sunlight by moving the umbrella pole along with the umbrella fabric, making it convenient for users to quickly adjust the shading angle of the parasol.

[0017] 2. In the sunshade of the present invention, the end of the umbrella pole away from the upright, the connecting arm, the transverse arm, and the sliding assembly are sequentially hinged together, and the hinge point of the connecting arm and the transverse arm is located on the transverse arm outside the included angle. First, the above-mentioned hinge method realizes that the end of the umbrella pole away from the upright, the connecting arm, the transverse arm, and the sliding assembly form a movable polygonal structure, so that when the sliding assembly slides on the umbrella pole, the connecting arm and the transverse arm can retract the umbrella fabric through an inward movement and open the umbrella fabric through an outward movement. Second, the hinge point is located outside the included angle of the connecting arm and the transverse arm and on the transverse arm, ensuring that the transverse arm and the connecting arm will not flip outward when the polygonal structure deforms, eliminating the phenomenon of the umbrella fabric flipping outward due to strong external wind force when retracted, and enhancing the stability and reliability of the sunshade when retracted and opened.

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The applicant hereby emphasizes that the following embodiments are one or more examples of achieving the technical solutions of the present invention, obtaining the corresponding technical effects, and solving the corresponding technical problems, but do not mean that the scope of protection of the technical solutions only includes the following embodiments.

[0036] according to Figures 1 to 16 As shown, the multi-directional adjustable parasol of the present invention mainly consists of a base 3, a column 1, and a frame 2. The base 3 is located on the ground and serves to fix the parasol and lower its center of gravity, ensuring it remains fixed in the same position even outdoors, unaffected by wind. The base 3 can be a one-piece structure or a spliced ​​structure. For the spliced ​​structure, one or more pairs of splicing blocks 34 and splicing grooves 35 can be provided on the vertical cross-sections of the two bases 3, allowing the bases 3 to be assembled together through the cooperation of the splicing blocks 34 and splicing grooves 35. The column 1 is located on the base 3, while the frame 2 is located on top of the column 1 and covered with a canopy 4, thus forming the shaded space under the base 3. The frame 2 includes a pole 21, a sliding assembly, and an arm assembly. The umbrella pole 21 is movably connected to the upper end of the column 1; there is at least one sliding component that can move back and forth on the umbrella pole 21; and the umbrella arm assembly is movably connected to both the sliding component and the umbrella pole 21, with the umbrella fabric 4 fixed to the umbrella arm assembly. By moving the sliding component on the umbrella pole 21, the umbrella arm assembly, carrying the umbrella fabric 4, opens or retracts, thereby opening or closing the sun umbrella.

[0037] In one embodiment of the present invention, the umbrella arm assembly includes a connecting arm 22 and a transverse arm 23, which are connected together by a hinge. The other end of the connecting arm 22 is hinged to the end of the umbrella rod 21 away from the column 1, and the other end of the transverse arm 23 is hinged to a sliding assembly. In the connection between the connecting arm 22 and the transverse arm 23, the connecting arm 22 and the transverse arm 23 intersect at a fixed angle, and the hinge point is located on the connecting arm 22 outside this angle. In this embodiment, the end of the umbrella rod 21, the connecting arm 22, the transverse arm 23, and the sliding assembly together form a deformable polygonal structure. During the deformation of this polygonal structure, the angle formed by the intersection of the connecting arm 22 and the transverse arm 23 remains unchanged. When the sliding assembly slides on the umbrella rod 21, the connecting end of the transverse arm 23 to the sliding assembly has a tension force in the same direction as the movement of the sliding assembly. At the connection end between the horizontal arm 23 and the connecting arm 22, since the length of one side of the polygon changes and the included angle between the connecting arm 22 and the horizontal arm 23 does not change due to their movement, this connection end is subjected to a pulling force opposite to the direction of movement of the sliding component. Under the action of two opposite pulling forces located at both ends of the horizontal arm 23, the horizontal arm 23 will rotate rapidly to achieve the outward support or retraction of the umbrella arm assembly. To make the connection between the connecting arm 22 and the horizontal arm 23 more stable, a connecting sleeve 26 can be provided between them. This connecting sleeve 26 is a triangular shape with a fixed angle, one end of which is fixed to the connecting arm 22, and the other end is movably hinged to the horizontal arm 23. In addition, a horizontal rod 27 can be provided at the end of the umbrella rod 21 away from the column 1, and the end of the horizontal rod 27 is movably hinged to the connecting arm 22. The ends of the horizontal rod 27, the connecting arm 22, the horizontal arm 23, and the sliding assembly form a deformable quadrilateral structure, increasing the range of motion at both ends of the horizontal arm 23, facilitating the rapid opening or closing of the sun umbrella, and further expanding the adaptability range of the umbrella fabric 4 size adjustment. Furthermore, to create an angle for the umbrella fabric 4 to facilitate water drainage, a horizontal inclined arm 231 can be provided above the horizontal arm 23, and a connecting inclined arm 221 can be provided above the connecting arm 22. Vertically, the horizontal inclined arm 231 and the connecting inclined arm 221 gradually decrease in the direction of extension from the umbrella rod 21 towards the connecting arm 22 and the horizontal arm 23. The horizontal inclined arm 231 achieves a movable hinge connection with the connecting sleeve 26 by being fixed together with the horizontal arm 23, while the connecting inclined arm 221 achieves a fixed connection with the connecting sleeve 26 by being fixed together with the connecting arm 22.

[0038] In another embodiment of the present invention, the sliding assembly mainly includes a sliding seat 24 and a roller assembly 25. The sliding seat 24 is disposed on the umbrella pole 21 and can move back and forth on the umbrella pole 21. The roller assembly 25 is located on the sliding seat 24 and is rolledly connected to two opposite planes of the umbrella pole 21 respectively. The connection relationship between the sliding assembly and other components described in this application can be understood by those skilled in the art as the connection between other components and the sliding seat 24. In this embodiment, the roller assembly 25 consists of a bracket 251 and rollers 252. The bracket 251 is fixed together with the sliding seat 24, while the rollers 252 are connected to the bracket 251 and can rotate around an axis. In addition, in order to adapt to the use of larger umbrella opening distances, two or more sliding assemblies can be provided on the umbrella pole 21, that is, the number of sliding seats 24 on the umbrella pole 21 can be two or more. It is important to note that as the sliding seat 24 slides on the umbrella pole 21, the force required for its opening and closing actions increases as the sliding seat 24 moves further away from the umbrella pole 21. Therefore, when there are two or more sliding seats 24, their lateral dimensions increase sequentially along the direction from the umbrella pole 21 away from the column 1. This structure gradually reduces the rotation distance of the umbrella arm assembly on the sliding seat 24 in the direction from the column 1 to the other end of the umbrella pole 21. Besides ensuring smoother outward support and retraction of the umbrella arm assembly, it also prevents the umbrella arm assembly from partially failing to open or close due to tension on the umbrella fabric 4. In fact, when the end of the umbrella pole 21 away from the column 1 has a transverse bar 27, the length of the transverse bar 27 is always greater than the maximum lateral dimension of the sliding seat 24, thereby improving the stability and reliability of the opening and closing of the umbrella arm assembly. In addition, when the umbrella arm assembly has a transverse inclined arm 231 and a connecting inclined arm 221, an upward extension 28 is also movably hinged to the sliding seat 24, and the end of the transverse inclined arm 231 is fixedly connected to the extension 28. The extension 28 also has a transverse portion 29, both ends of which are movably hinged to the extension 28 and to the connecting inclined arm 221. This structure, through the primary hinge of the transverse inclined arm 231 and the secondary hinge of the connecting inclined arm 221, ensures that when the sliding seat 24 slides on the umbrella rod 21, the rotational torque of the connecting inclined arm 221 and the connecting arm 22 is always greater than the rotational torque of the transverse inclined arm 231 and the transverse arm 23, thus ensuring the stability of the umbrella fabric 4 when opening and closing.

[0039] In another embodiment of the present invention, a first rotating mechanism is provided between the umbrella pole 21 and the column 1. This first rotating mechanism can move up and down along the vertical direction of the column 1 and drive the umbrella pole 21 to rotate around an axis. The first rotating adjustment mechanism includes a first base 11, a first rotating part 12, and a first locking block 13. The first base 11 is movably connected to the column 1 and can move up and down along the column 1. A positioning pin 17 can be provided on the first base 11 to fix its position on the column 1. The first rotating part 12 is disposed on the first base 11 and coaxially arranged with the sliding assembly. The first rotating part 12 can rotate around an axis, and the end of the umbrella pole 21 is located below the axis of the first rotating part 12 and is connected to it by a hinge. The first locking block 13 is located on the first base 11 and is movably connected to it. The first locking block 13 can engage with the first rotating part 12 to stop the first rotating part 12 from rotating. Furthermore, a positioning block 14 is fixed on the column 1, and a rotating shaft 15 is mounted on the positioning block 14. The rotating shaft 15 passes through the sliding assembly, allowing the sliding assembly to rotate around the rotating shaft 15, and the rotating shaft 15 is coaxially arranged with the first rotating part 12. In this embodiment, the first base 11 and the column 1 can be slidably connected, or a rolling wheel assembly 25 composed of a bracket 251 and rollers 252 can be provided to achieve its reciprocating movement on the umbrella pole 21. When the first base 11 and the column 1 are slidably connected, because the contact area between the first base 11 and the column 1 is large, its specific surface area is also large, so the contact surface between the first base 11 and the column 1 is not prone to adhering to dust or particles. When the first base 11 is connected to the column 1 by a roller assembly 25, the roller assembly 25 continuously rolls on the column 1 when the sunshade is opened or closed. Therefore, particles or dust are easily blown away by the external wind by adhering to the surface of the column 1, and the roller assembly 25 will not accumulate too much dust or particles. The end of the umbrella pole 21 is located below the axis of the first rotating part 12 and is movably hinged to the first rotating part 12. This structure allows the umbrella pole 21 to be vertically retracted when the first base 11 moves downward. Since the sliding component is sleeved on the umbrella pole 21, the sliding component needs to rotate to turn the umbrella pole 21 when it needs to be vertically retracted. In this embodiment, a connecting block 16 can be provided between the rotating shaft 15 and the sliding component. One end of the connecting block 16 is sleeved on the rotating shaft 15 and can rotate around the rotating shaft 15, while the other end is movably hinged to the sliding component. In this embodiment, the first rotating part 12 can adopt a fitting structure, with a first rotating block 121 and a first turntable 122 respectively provided at both ends of the circular through hole of the first base 11. The first rotating block 121 and the first turntable 122 are coaxially connected together, and a first latch 123 is provided on the first turntable 122. The first latch 123 can be partially opened at the outer edge of the first turntable 122 or evenly distributed, and it can be engaged with the first latch 13 to stop the rotation of the first rotating part 12.An adjusting arm 124 can also be provided on the outside of the first turntable 122, and the adjusting arm 124 is movably hinged to the end of the umbrella rod 21.

[0040] In another embodiment of the present invention, a second rotation adjustment mechanism may be provided between the column 1 and the base 3. This second rotation adjustment mechanism includes a second seat 31, a second rotating part 32, and a second locking block 33. The second seat 31 is fixed to the base 3 by screws or a snap-fit ​​connection. The second rotating part 32 is disposed on the second seat 31, fixed to the column 1, and can rotate around an axis. The second seat 31 is also provided with a second locking block 33, which is movably connected to the second seat 31 and can engage with the second rotating part 32 to stop its rotation. In this embodiment, the second rotating part 32 may also adopt a fitting structure, with a second rotating block 321 and a second rotating disk 322 respectively disposed at both ends of the circular through hole of the second seat 31. The second rotating block 321 and the second turntable 322 are coaxially connected together, and the second turntable 322 is provided with a second latch 323. The second latch 323 can be partially opened at the outer edge of the second turntable 322 or evenly distributed on the outer edge of the second turntable 322. It can be matched and engaged with the second latch 33 to stop the rotation of the second rotating part 32.

[0041] When using the sun umbrella of the present invention, the first base 11 is pushed towards the upper end of the column 1. Under the action of the first base 11 and the lateral limiting effect of the sliding component, the umbrella rod 21 gradually changes from vertical movement to horizontal rotation. When the umbrella rod 21 rotates horizontally, the end away from the column 1 continuously pulls the connecting arm 22, the horizontal arm 23 and the sliding component, causing the connecting arm 22 and the horizontal arm 23 to open along with the umbrella fabric 4. When the first base 11 moves to the top of the column 1, the first base 11 can be fixed by tightening the positioning pin 17, at which point the sun umbrella is in the open state. When the angle of the umbrella fabric 4 needs to be adjusted according to the angle of sunlight, the user only needs to pry open the first locking block 13 and disengage it from the first turntable 122, then move the adjusting arm 124. The first rotating block 121 and the first turntable 122 rotate simultaneously, the rotating shaft 15 drives the sliding component to rotate, and the umbrella rod 21 rotates around the rotating shaft 15 below it. The plane of the umbrella fabric 4 rotates around the axis of the umbrella rod 21, so that the umbrella fabric 4 can be easily tilted to block sunlight according to the angle of sunlight. In addition, the user can pry open the second locking block 33 and disengage it from the second turntable 322, and then rotate the column 1, so that the position of the umbrella fabric 4 can be easily adjusted on a circle with the column 1 as the center and the umbrella rod 21 as the radius.
