Description

Folding umbrella

[0001] This disclosure claims priority to Chinese patent application No. CN2024227209382, filed on November 8, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to a folding umbrella. Background Technology

[0003] Some folding umbrellas have a rotating handle on their support pole. For example, some folding umbrellas control the opening and closing of the top frame by operating the rotating handle. The rotating handle usually includes a crank that can rotate relative to the support pole and a grip for the user to hold. When in use, the user holds the grip to drive the crank to rotate. The extension direction of the grip is usually at an angle to the support pole for the user to operate. However, when the rotating handle is not in use, the grip protrudes to one side of the support pole, which not only affects the appearance of the folding umbrella, but also makes it easy to collide with the user under the umbrella, resulting in poor safety. At the same time, if the grip is accidentally touched, it may affect the state of the folding umbrella, making the folding umbrella less stable.

[0023] In some embodiments, the telescopic member includes a main body and an abutment portion. The main body extends along the first direction, and the abutment portion is fixed to one end of the main body near the receiving cavity. The receiving cavity has an opening for inserting the handle therein, the diameter of which is smaller than the diameter of the abutment portion. In the second state, the abutment portion is located within the receiving cavity and abuts against the opening. The opening limits the telescopic member, and in the second state, the abutment portion blocks the opening, preventing contamination of the inside of the receiving cavity.

[0041] The technical solutions of the embodiments of this disclosure will now be clearly and completely described with reference to the accompanying drawings, so that the advantages and features of this disclosure can be more easily understood by those skilled in the art. Obviously, the embodiments described in this disclosure are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0042] Referring to Figures 1 and 4, a folding umbrella includes a central support rod 1 and a top frame 2 capable of unfolding and folding relative to the central support rod 1. The folding umbrella also includes a handle mechanism 3, which comprises a crank 31 and a grip 33. The crank 31 is rotatably connected to the central support rod 1, and the grip 33 is movably connected to the crank 31. The folding umbrella also includes a receiving cavity 34. The handle mechanism 3 has a first state and a second state. In the first state, the grip 33 is housed within the receiving cavity 34, resulting in a cleaner appearance and improved aesthetics of the folding umbrella, while also preventing accidental contact with the grip 33. In the second state, the grip 33 is laterally positioned relative to the crank 31 for gripping, and the handle mechanism 3 allows the crank 31 to rotate relative to the central support rod 1.

[0043] In this embodiment, the crank handle 31 is rotatably mounted on the central support rod 1 about a rotation center line X1. The extension direction of the rotation center line X1 is perpendicular to the axial direction of the central support rod 1. The grip 33 is arranged transversely to the crank handle 31 and can be movably connected to the crank handle 31 along its own axial direction. In this embodiment, the receiving cavity 34 is disposed between the central support rod 1 and the handle mechanism 3. When the grip 33 corresponds to the receiving cavity 34, by driving the grip 33 to move along its own axial direction into the receiving cavity 34, the grip 33 can be received in the receiving cavity 34, thereby converting the handle mechanism 3 to a first state. In the second state, the grip 33 is withdrawn axially from the receiving cavity 34, thereby enabling the crank handle 31 to rotate using the grip 33. In some embodiments, the central support rod 1 has a receiving cavity 34, and when the handle mechanism 3 is in the first state, the grip 33 is received in the central support rod 1.

[0044] In other embodiments, the handle 33 is foldable relative to the crank handle 31. When the handle 33 is folded relative to the crank handle 31, the handle mechanism 3 transitions to a first state; when the handle 33 is unfolded relative to the crank handle 31, the handle mechanism 3 transitions to a second state. Specifically, referring to the handle mechanism 3 shown in Figures 10 to 12, the handle 33 is rotatably connected to the crank handle 31 about a rotation axis X2, and the handle 33 can rotate and fold relative to the crank handle 31. In this embodiment, the handle mechanism 3 is provided with a receiving cavity 34. Specifically, the crank handle 31 has a receiving cavity 34, which is elongated and extends along the length of the crank handle 31. The crank handle 31 has an opening communicating with the receiving cavity 34, allowing the handle 33 to be received into the receiving cavity 34 from the opening. In this embodiment, openings communicating with the receiving cavity 34 are provided on both sides of the crank handle 31 in the thickness direction. In this embodiment, the handle 33 has a connecting end and a free end located at opposite ends to its length direction. The connecting end extends into the receiving cavity 34 on the side away from the rotation center line X1, and is rotatably connected to the crank handle 31 around the rotation axis X2. Referring to Figure 12, in the second state, the free end extends to the side of the crank handle 31 away from the central support rod 1 for the user to grip. Referring to Figures 10 and 11, in the first state, the handle 33 is housed within the receiving cavity 34. In this embodiment, the length of the receiving cavity 34 is greater than the length of the handle 33, leaving an operating space between the free end of the handle 33 and the cavity wall of the receiving cavity 34 in the first state. The user can insert their fingers into this operating space to rotate the handle 33, thereby changing the handle mechanism 3 from the first state to the second state. The user can also use the lever principle to press the connecting end to rotate the handle 33, thus changing the handle mechanism 3 to the second state.

[0045] In this embodiment, the handle mechanism 3 includes a mounting base 36 sleeved and fixed to the outside of the central support rod 1, and a receiving cavity 34 formed on the mounting base 36 and extending into the rod cavity 11 of the central support rod 1. In this embodiment, the handle mechanism 3 also includes a telescopic assembly 35, which includes a telescopic member 351 movably disposed on the central support rod 1 along a first direction. In a first state, the telescopic member 351 retracts from the receiving cavity 34, and the first direction is parallel to or the same as the axial direction of the handle 33. Specifically, the first direction is the length extension direction of the receiving cavity 34. Referring to Figures 2 and 8, in this state, along the first direction, on the side of the crank 31 away from the central support rod 1, the outer surface of the crank 31 smoothly transitions to the surface of the handle 33, making it more aesthetically pleasing. Simultaneously, the handle 33 is less likely to be accidentally touched, improving the stability and safety of the folding umbrella. In the second state, as shown in Figures 3 and 9, the telescopic member 351 extends into the receiving cavity 34, causing the handle 33 to be pushed out of the receiving cavity 34, and the user can use the handle 33 to turn the crank 31.

[0046] In this embodiment, pressing the handle 33 axially allows the handle mechanism 3 to switch between a first state and a second state, simplifying the switching operation. Specifically, the telescopic component 35 includes a fixed base 352, which is fixedly disposed in the receiving cavity 34 on the side away from the crank handle 31 along a first direction. The telescopic member 351 can move along the first direction and connect with the fixed base 352. A locking mechanism is provided between the fixed base 352 and the telescopic member 351. When the handle mechanism 3 is in the first state, the telescopic member 351 moves closer to the fixed base 352, and the locking mechanism is locked. In this state, the telescopic member 351 will not affect the handle 33 located in the receiving cavity 34. When the locking mechanism is unlocked, the telescopic member 351 can move relative to the fixed base 352 along the first direction. The telescopic assembly 35 also includes an elastic element 353, which is disposed between the fixed base 352 and the telescopic element 351. The elastic element 353 is used to provide the force required for the telescopic element 351 to move away from the fixed base 352. Thus, when the locking mechanism is in the unlocked state, under the drive of the elastic element 353, the telescopic element 351 can automatically move away from the fixed base 352 and automatically extend into the receiving cavity 34, thereby automatically pushing the handle 33 located in the receiving cavity 34 out of the receiving cavity 34, realizing the conversion of the handle mechanism 3 to the second state.

[0047] In this embodiment, pressing the telescopic member 351 can drive the locking mechanism to switch between a locked state and an unlocked state. When the handle 33 and the receiving cavity 34 extend in the same direction, pressing the handle 33 in the first direction can push the telescopic member 351 to move, thereby pressing the telescopic member 351. Thus, pressing the handle 33 can lock and unlock the locking mechanism. Specifically, when the telescopic member 351 is inserted into the receiving cavity 34, the locking mechanism is in the unlocked state. Pressing the handle 33 in the first direction pushes the telescopic member 351 towards the fixed seat 352. During this process, the locking mechanism switches to the locked state, and the telescopic member 351 can be locked together with the fixed seat 352. During the pressing of the handle 33, the telescopic member 351 gradually exits the receiving cavity 34, and when the telescopic member 351 and the fixed seat 352 are locked together, the handle 33 is housed in the receiving cavity 34, and the handle mechanism 3 switches to the first state. In the first state, pressing the handle 33 along the first direction causes the handle 33 to push the telescopic member 351 to move and release the locking mechanism. Driven by the elastic member 353, the telescopic member 351 can move into the receiving cavity 34 and push the handle 33 out, thereby causing the handle mechanism 3 to switch to the second state.

[0048] In this embodiment, along the first direction, the mounting base 36 has a fixing groove on the side away from the receiving cavity 34. The fixing base 352 extends along the first direction, with one end of the fixing base 352 inserted into the fixing groove and the other end of the fixing base 352 extending into the rod cavity 11 of the central support rod 1. In this embodiment, the mounting base 36 is provided with two fixing rods 361. When the mounting base 36 is fixed on the central support rod 1, the two fixing rods 361 extend along the same length direction. The length extension direction of the fixing rods 361 is perpendicular to the first direction. Along the length extension direction of the fixing rods 361, the fixing base 352 is located between the two fixing rods 361. The two fixing rods 361 abut against both sides of the fixing base 352 and fix the fixing base 352.

[0049] In this embodiment, the mounting base 36 has an opening 341 on its side near the crank handle 31, which communicates with the receiving cavity 34 for the grip 33 to be inserted into the receiving cavity 34. In this embodiment, the telescopic member 351 has a main body 351a and abutting part 351b. The main body 351a extends along a first direction, and the abutting part 351b is fixed at one end of the telescopic member 351 near the receiving cavity 34. In the first state, the abutting part 351b abuts against the grip 33. During the state transition of the handle mechanism 3, the grip 33 pushes the abutting part 351b to move, or the abutting part 351b pushes the grip 33 to move. In this embodiment, the diameter of the opening 341 is smaller than the diameter of the abutting part 351b. When the handle mechanism 3 is in the second state, the abutting part 351b is located inside the receiving cavity 34, and under the force of the elastic member 353, the abutting part 351b abuts against the opening 341. In this embodiment, the opening 341 limits the telescopic member 351. Meanwhile, in the second state, the abutment part 351b is blocked at the opening 341, which can prevent the inside of the accommodating cavity 34 from being contaminated.

[0050] In this embodiment, the telescopic member 351 is mounted on the fixed base 352, capable of moving along a first direction and rotating along its own axis. The locking mechanism includes a protrusion 3522 fixed on the fixed base 352 and a locking groove 3511 mounted on the telescopic member 351. The locking groove 3511 is located at the end of the telescopic member 351 near the receiving cavity 34, with the opening of the locking groove 3511 facing the receiving cavity 34. When the locking mechanism is in the locked state, the protrusion 3522 is engaged in the locking groove 3511. During the unlocking process, the telescopic member 351 rotates around its axis, causing the protrusion 3522 to move circumferentially along the telescopic member 351. When the locking mechanism is in the unlocked state, the protrusion 3522 disengages from the locking groove 3511. In some embodiments, the protrusion 3522 is fixed on the telescopic member 351, and the locking groove 3511 is located at the end of the fixed base 352 away from the receiving cavity 34, with the opening of the locking groove 3511 away from the receiving cavity 34.

[0051] Specifically, referring to Figures 6 and 7, the fixed base 352 has a hollow cavity 3521 extending along a first direction, and a telescopic member 351 extending along the first direction is movably inserted into the hollow cavity 3521. A protrusion 3522 extends inwardly from the cavity wall of the hollow cavity 3521, and a locking groove 3511 is formed on the outer wall of the telescopic member 351. Referring to Figure 6, in this embodiment, the protrusion 3522 is located at one end of the fixed base 352 near the receiving cavity 34. Under the action of the elastic member 353, the telescopic member 351 is driven to move towards the receiving cavity 34, so that in the locked state, the protrusion 3522 always abuts against the groove wall of the locking groove 3511, and the locking mechanism can stably maintain the locked state.

[0052] In this embodiment, the outer wall of the telescopic member 351 is also provided with a guide groove 3512 extending along a first direction. Along the circumference of the telescopic member 351, the guide groove 3512 is adjacent to the locking groove 3511, and the guide groove 3512 provides guidance for the movement of the protrusion 3522. When the handle mechanism 3 transitions from the first state to the second state, the locking mechanism is in the unlocked state, and the protrusion 3522 enters the guide groove 3512 from the locking groove 3511, allowing it to move along the guide groove 3512. In the second state, the protrusion 3522 is located in the guide groove 3512.

[0053] In this embodiment, along the circumference of the hollow cavity 3521, a plurality of protrusions 3522 are spaced apart on the cavity wall of the hollow cavity 3521. The telescopic member 351 is provided with a plurality of locking grooves 3511 corresponding to the number of protrusions 3522, and a plurality of guide grooves 3512 corresponding to the number of protrusions 3522. Along the circumference of the telescopic member 351, the plurality of locking grooves 3511 and guide grooves 3512 are alternately distributed. When the locking mechanism switches between the locked state and the unlocked state, the protrusions 3522 move relative to the telescopic member 351 along the circumference of the telescopic member 351, thereby moving from the locking groove 3511 to the guide groove 3512, or from the guide groove 3512 to the locking groove 3511. As the state of the locking mechanism is continuously switched, the protrusions 3522 will move around the telescopic member 351 in a clockwise or counterclockwise direction, and in this process, the protrusions 3522 will enter the alternately distributed locking grooves 3511 and guide grooves 3512 one by one.

[0054] In this embodiment, as shown in Figure 7, a guide channel 3510 is provided around the outer wall of the telescopic member 351. The guide channel 3510 is recessed inward from the outer wall of the telescopic member 351, and a guide groove 3512 is also recessed inward from the outer wall of the telescopic member 351. The guide groove 3512 and the guide channel 3510 are interconnected. The locking groove 3511 is provided on the side wall of the guide channel 3510 away from the receiving cavity 34. During the state transition of the locking mechanism, the protrusion 3522 always moves within the interconnected guide channel 3510 and guide groove 3512, making the locking mechanism more stable.

[0055] In this embodiment, a driving structure is provided between the fixed base 352 and the telescopic member 351, which is used to drive the telescopic member 351 to rotate around its own axis when the telescopic member 351 is pressed, so that the protrusion 3522 moves circumferentially along the telescopic member 351, thereby realizing the conversion of the locking mechanism state. In this embodiment, the driving structure includes a first inclined surface 3523 provided on the protrusion 3522, and a first guide surface 3513 and a second guide surface 3514 provided on the telescopic member 351. The first guide surface 3513 and the second guide surface 3514 extend obliquely along the axial direction of the telescopic member 351. Preferably, the first guide surface 3513 and the second guide surface 3514 extend obliquely along the circumferential direction of the telescopic member 351. Specifically, along the circumferential direction of the telescopic member 351, each locking groove 3511 has a first guide groove 3512a and a second guide groove 3512b adjacent to it on both sides. Along the circumferential direction of the telescopic member 351, the first guide surface 3513 extends from the first guide groove 3512a to the locking groove 3511, and the second guide surface 3514 extends from the locking groove 3511 to the second guide groove 3512b. The first guide surface 3513 is used to slide in cooperation with the first inclined surface 3523 to make the protrusion 3522 move closer to the locking groove 3511, and the second guide surface 3514 is used to slide in cooperation with the first inclined surface 3523 to make the protrusion 3522 move away from the locking groove 3511.

[0056] Specifically, as shown in Figure 7, the first guide surface 3513 and the second guide surface 3514 are disposed on the side wall of the guide channel 3510 near the receiving cavity 34. Along the circumferential direction of the telescopic member 351, the first guide surface 3513 extends from the first guide groove 3512a to the locking groove 3511. At the same time, along the axial direction of the telescopic member 351, the first guide surface 3513 extends obliquely towards the receiving cavity 34. Along the circumferential direction of the telescopic member 351, the second guide surface 3514 extends from the locking groove 3511 to the second guide groove 3512b. At the same time, along the axial direction of the telescopic member 351, the second guide surface 3514 extends obliquely towards the receiving cavity 34.

[0057] When the handle mechanism 3 is switched to the first state, when the telescopic member 351 is pressed by the grip 33, the telescopic member 351 moves closer to the fixed seat 352, and the protrusion 3522 moves closer to the abutment along the first guide groove 3512a. During this process, the first inclined surface 3523 contacts the first guide surface 3513, and the two slide together, causing the protrusion 3522 to continue to move closer to the abutment. At the same time, the protrusion 3522 moves closer to the locking groove 3511 along the circumference of the telescopic member 351. When the grip 33 is released, the telescopic member 351 is also released. Driven by the elastic member 353, the telescopic member 351 moves away from the fixed seat 352. During this process, the protrusion 3522 separates from the first guide surface 3513 and moves towards the side wall of the guide channel 3510 away from the receiving cavity 34, thereby entering the locking groove 3511. When the drive handle mechanism 3 is switched to the second state, when the telescopic member 351 is pressed by the grip 33, the protrusion 3522 moves closer to the abutment and disengages from the locking groove 3511. When the first inclined surface 3523 contacts the second guide surface 3514, the two slide together, causing the protrusion 3522 to move away from the locking groove 3511 circumferentially. When the grip 33 is released, the protrusion 3522 moves toward the side wall of the guide channel 3510 away from the receiving cavity 34.

[0058] In this embodiment, the projection of the first guide groove 3512a along the first direction falls into the projection of the first guide surface 3513 along the first direction, thus ensuring that when the protrusion 3522 moves along the first guide groove 3512a towards the abutment, the protrusion 3522 can contact the first guide surface 3513. In this embodiment, the first guide surface 3513 has a first end and a second end located at opposite ends in the length direction, wherein the first end is close to the first guide groove 3512a, the second end is close to the locking groove 3511, and the projection of the second end along the first direction falls into the projection of the locking groove 3511 along the first direction. This ensures that when the handle 33 is released, i.e., when the telescopic member 351 is released, the protrusion 3522 can enter the locking groove 3511 under the action of the elastic member 353.

[0059] In this embodiment, the second guide surface 3514 has a third end near the locking groove 3511 and a fourth end away from the locking groove 3511. The locking groove 3511 has a first groove wall near the first guide groove 3512a and a second groove wall near the second guide groove 3512b. The projection of the third end in the first direction falls into the projection of the first groove wall in the first direction. Thus, when transitioning to the second state, it can be ensured that the protrusion 3522 can contact the second guide surface 3514 after disengaging from the locking groove 3511.

[0060] In this embodiment, the driving structure further includes a third guide surface 3515 and a fourth guide surface 3516 disposed on the telescopic member 351, and a second inclined surface 3524 disposed on the protrusion 3522. Along the first direction, the first inclined surface 3523 and the second inclined surface 3524 are disposed on opposite sides of the protrusion 3522, wherein the first inclined surface 3523 is located on the side closer to the receiving cavity 34, and the second inclined surface 3524 is located on the side farther from the receiving cavity 34. Along the circumferential direction of the telescopic member 351, the third guide surface 3515 extends from the first guide groove 3512a to the locking groove 3511. Simultaneously, along the axial direction of the telescopic member 351, the third guide surface 3515 extends obliquely away from the receiving cavity 34. The third guide surface 3515 is used to slide in cooperation with the second inclined surface 3524, causing the protrusion 3522 to move towards the bottom of the locking groove 3511. In this embodiment, the first groove wall constitutes the third guide surface 3515. A fourth guide surface 3516 is disposed on the side wall of the guide channel 3510 away from the receiving cavity 34, and is located between the locking groove 3511 and the second guide groove 3512b. Along the circumferential direction of the telescopic member 351, the fourth guide surface 3516 extends from the second guide surface 3514 to the second guide groove 3512b. Simultaneously, along the axial direction of the telescopic member 351, the fourth guide surface 3516 extends obliquely away from the receiving cavity 34. The fourth guide surface 3516 is used to slide in cooperation with the second inclined surface 3524, allowing the protrusion 3522 to enter the second guide groove 3512b. In this embodiment, the projection of the fourth end in the first direction falls into the projection of the fourth guide surface 3516 in the first direction. Thus, when transitioning to the second state, when releasing the handle 33 and the telescopic member 351, the protrusion 3522 can smoothly contact the fourth guide surface 3516 under the drive of the elastic member 353.

[0061] In this embodiment, the locking groove 3511 is V-shaped, which allows the protrusion 3522 to enter the locking groove 3511 or disengage from it more smoothly under the action of the driving structure during the state transition. At the same time, when the locking mechanism is in the locked state, the protrusion 3522 can be inserted more stably into the V-shaped locking groove 3511.

[0062] In this embodiment, the driving mechanism includes a first stop groove and a second stop groove. The openings of the first stop groove and the second stop groove both face away from the receiving cavity 34, and both the first stop groove and the second stop groove are disposed on the side wall of the guide channel 3510 near the receiving cavity 34. The first stop groove is disposed between the first guide groove 3512a and the locking groove 3511, and the second stop groove is disposed between the locking groove 3511 and the second guide groove 3512b. In this embodiment, both the first stop groove and the second stop groove are V-shaped. The groove wall of the first stop groove near the first guide groove 3512a forms a first guide surface 3513, and the groove wall of the second stop groove near the locking groove 3511 forms a second guide surface 3514.

[0063] The specific process of the handle mechanism 3 transitioning to the first state is as follows: Press the handle 33 along the first direction, and the handle 33 pushes the telescopic member 351 located in the accommodating cavity 34 to move, so that the telescopic member 351 is disengaged from the accommodating cavity 34. During this process, the protrusion 3522 moves along the first guide groove 3512a to the guide channel 3510. When the protrusion 3522 contacts the first guide surface 3513, the first inclined surface 3523 slides in cooperation with the first guide surface 3513, causing the protrusion 3522 to move along the circumference of the telescopic member 351 towards the locking groove 3511 until the protrusion 3522 moves to the bottom of the first stop groove. At this time, the handle 33 can no longer move forward. The handle 33 is released, and the telescopic member 351 moves towards the receiving cavity 34 under the drive of the elastic member 353. During this process, the protrusion 3522 moves towards the side wall of the guide channel 3510 away from the receiving cavity 34. The protrusion 3522 contacts the third guide surface 3515, and the second inclined surface 3524 slides in cooperation with the third guide surface 3515, causing the protrusion 3522 to move to the bottom of the locking groove 3511. At this time, the telescopic member 351 stops moving, and the handle 33 is successfully received in the receiving cavity 34.

[0064] The process of the handle mechanism 3 transitioning from the first state to the second state is as follows: Pressing the handle 33 pushes the telescopic member 351 away from the receiving cavity 34. During this process, the protrusion 3522 disengages from the locking groove 3511 and moves towards the side wall of the guide channel 3510 near the abutment. When the protrusion 3522 contacts the second guide surface 3514, the first inclined surface 3523 slides in cooperation with the second guide surface 3514, and the protrusion 3522 moves towards the second guide surface 3514 along the circumference of the telescopic member 351. The guide groove 3512b moves until the protrusion 3522 reaches the bottom of the second stop groove. At this point, the handle 33 is released, and the telescopic member 351 moves towards the receiving cavity 34 under the drive of the elastic member 353. During this process, the protrusion 3522 contacts the fourth guide surface 3516, and the second inclined surface 3524 slides in cooperation with the fourth guide surface 3516, allowing the protrusion 3522 to continue moving towards the second guide groove 3512b until it enters the second guide groove 3512b. After the protrusion 3522 enters the second guide groove 3512b, it moves away from the receiving cavity 34 along the second guide groove 3512b, and the telescopic member 351 extends into the receiving cavity 34 and pushes the handle 33 out. When the abutting part abuts against the opening 341 of the receiving cavity 34, the telescopic member 351 stops moving, and the handle 33 is completely disengaged from the receiving cavity 34.

[0065] In this embodiment, at the end away from the receiving cavity 34, the telescopic member 351 is also provided with an installation channel 3517. The number of installation channels 3517 corresponds to the number of protrusions 3522, and the installation channel 3517 is used to connect the fixing seat 352 and the telescopic member 351. One end of the installation channel 3517 is connected to the guide groove 3512, and the other end is connected to the outside of the telescopic member 351. When the fixing seat 352 and the telescopic member 351 are connected, the protrusions 3522 enter the guide groove 3512 from the installation channel 3517. In this embodiment, referring to Figure 7, the installation channel 3517 is L-shaped and has a first section and a second section that are interconnected. The first section extends from the end of the telescopic member 351 away from the receiving cavity 34 along a first direction, and the second section extends from the first section along the circumference of the telescopic member 351 towards the guide groove 3512. Along the first direction, the end of the guide groove 3512 away from the receiving cavity 34 extends beyond the second section to prevent the protrusion 3522 from entering the second section when the handle mechanism 3 is in the second state, thus affecting the normal operation of the telescopic component.

[0066] In this embodiment, the top frame 2 includes multiple support units 21, which are supported by a central support rod 1 and can be unfolded and folded relative to each other. Each support unit 21 includes a first top rod 211 and a second top rod 212, with the inner end of each first top rod 211 rotatably connected to the upper end of the central support rod 1. The folding umbrella also includes a slider 4 slidably disposed on the central support rod 1 in the vertical direction. The slider 4 is offset from the upper end of the central support rod 1, and the inner end of each second top rod 212 is rotatably connected to the slider 4. The first top rod 211 and the second top rod 212 are also rotatably connected to form a crank-slider mechanism between the first top rod 211, the second top rod 212, the central support rod 1, and the slider 4. By driving the slider 4 to move along the central support rod 1, each support unit 21 can be unfolded or folded relative to the central support rod 1, thereby allowing the folding umbrella to switch between the unfolded and folded states. Specifically, referring to Figure 1, driving the slider 4 away from the upper end of the central support rod 1 causes the inner end of the second push rod 212 to move downward, causing the second push rod 212 to fold relative to the central support rod 1. The second push rod 212 also causes the first push rod 211 to fold relative to the central support rod 1, thus converting the folding umbrella to a folded state. Driving the slider 4 closer to the upper end of the central support rod 1 causes the inner end of the second push rod 212 to move upward, causing the second push rod 212 to unfold relative to the central support rod 1 and driving the first push rod 211 to unfold relative to the central support rod 1, thus converting the folding umbrella to an unfolded state.

[0067] In this embodiment, a rotating shaft 32 is fixedly mounted on one end of the crank handle 31. The axis of the rotating shaft 32 extends collinearly with the rotation center line X1. The rotating shaft 32 is rotatably connected to the central support rod 1 around its own axis. During the rotation of the crank handle 31 via the grip 33, the rotating shaft 32 rotates around its own axis. Referring to Figures 5 and 9, in this embodiment, the grip 33 and the rotating shaft 32 are located at opposite ends along the length of the crank handle 31. This arrangement increases the distance between the grip 33 and the rotating shaft 32, thereby increasing the lever arm length for rotating the crank handle 31. This results in less resistance when rotating the crank handle 31 via the grip 33, making rotation easier.

[0068] In this embodiment, rotating the crank 31 can drive the top frame 2 to unfold or fold, thereby allowing the folding umbrella to switch between the unfolded and folded states. Specifically, a traction mechanism is provided between the rotating shaft 32 and the slider 4. During the rotation of the rotating shaft 32, the traction mechanism can drive the slider 4 to slide along the central support rod 1, thereby realizing the unfolding or folding of the top frame 2. Specifically, the traction mechanism includes a traction line 5 connected between the slider 4 and the rotating shaft 32. One end of the traction line 5 is fixed to the rotating shaft 32. By rotating the rotating shaft 32 with the crank 31, the traction line 5 can be wound around the rotating shaft 32, thereby driving the slider 4 to move. In this embodiment, referring to Figures 5 and 8, a ratchet 37 is fixed on the rotating shaft 32, and a pawl and a second elastic element that drives the pawl to abut against the ratchet 37 are rotatably provided on the central support rod 1. Specifically, the pawl and the second elastic element are provided on the mounting base 36. The pawl and ratchet 37 work together to prevent the shaft 32 and the crank 31 from turning backward, thus preventing the top frame 2 from automatically folding under its own weight or other external forces. When the crank 31 is manually turned backward, the ratchet 37 can push the pawl aside and rotate.

[0069] In summary, the folding umbrella of this embodiment controls the opening and closing of the top frame 2 by rotating the crank handle 31 via the handle 33. When it is not necessary to rotate the crank handle 31, pressing the handle 33 axially converts the handle mechanism 3 to a first state. In this state, the handle 33 is housed within the receiving cavity 34, which is not only more aesthetically pleasing but also prevents collisions or accidental contact with people, thus improving the safety and stability of the folding umbrella. The user only needs to press the handle 33 axially again to drive the handle mechanism 3 from the first state to the second state. In this state, the handle 33 extends from the receiving cavity 34, and the user can drive the crank handle 31 to rotate via the handle 33.
