Description

Technical Field

[0001] This utility model belongs to the field of sunshade technology and relates to a sunshade with zone control. Background Technology

[0002] As people's living standards improve, they engage in outdoor leisure activities more frequently. In recreational places such as squares, lawns, and beaches, sun umbrellas have become a common tool, providing people with a comfortable space to cool off.

[0003] Existing patent document CN119563980A discloses an outdoor sunshade with an umbrella column lifting structure, comprising an umbrella column assembly and an umbrella frame assembly. The umbrella column assembly includes an upper umbrella column and a lower umbrella column, which are slidably coupled and are provided with a lifting adjustment mechanism between them. The lifting adjustment mechanism is used to raise or lower the upper umbrella column relative to the lower umbrella column and can be locked at any height. The umbrella frame assembly is installed on the upper umbrella column and can be raised or lowered by the upper umbrella column. A handrail shell assembly is fitted on the upper umbrella column, which is slidably connected to the upper umbrella column and can be locked at any position. The handrail shell assembly can control the opening and closing of the umbrella frame assembly during sliding.

[0004] However, the aforementioned existing technologies still have the following shortcomings:

[0005] In the existing technology, the umbrella canopy is unfolded by the armrest shell assembly, and the tilt angle of the umbrella canopy is adjusted by manually pushing and pulling the armrest shell assembly along the upper umbrella column. When the armrest shell assembly is pushed to the highest point of the upper umbrella column and locked, the user needs to open and close the umbrella canopy. Shorter users cannot reach the armrest shell assembly. The existing technology does not take into account the ease of operation for users of different heights, making it difficult for shorter users to open and close the raised umbrella canopy.

[0006] In existing armrest housing components, the paracord routing passes through the armrest housing component, causing the locking components on the armrest housing component to be far away from the umbrella frame. This results in greater resistance during movement of the armrest housing component, making it more difficult for users to push or pull it. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sunshade with zone control to solve the problems mentioned in the background technology. This utility model is suitable for people of different heights to open and close the umbrella surface. It is convenient to operate, has a wide range of applications, and allows users to push and pull the armrest shell with less effort, thereby quickly adjusting the angle of the umbrella surface.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0009] A zone-controlled parasol includes an umbrella column and an umbrella frame. A handrail shell is slidably installed on the inner side of the umbrella column and can be locked at any target position on the umbrella column. A support arm is hinged to one end of the handrail shell and is fixedly connected to the umbrella frame. A suspension arm is hinged to the middle of the support arm and one end of the suspension arm is hinged to the top of the umbrella column. A crank is installed in the middle of the umbrella column, and an umbrella cord is wound on the crank. The umbrella cord is used to drive the umbrella frame to open or close. The umbrella cord starts from the crank, passes through the umbrella column, the suspension arm, and the support arm in sequence, and finally connects to the bottom of the umbrella frame.

[0010] Furthermore, the umbrella column, suspension arm, and support arm are hollow inside and each is rotatably equipped with a fixed pulley.

[0011] Furthermore, the umbrella frame includes an upper umbrella disc body, a lower umbrella disc body, and multiple umbrella rib structures that are fitted onto the upper umbrella disc body and the lower umbrella disc body. The upper umbrella disc body is fixedly connected to the support arm, and one end of the umbrella rope is connected to the lower umbrella disc body.

[0012] When the handle is cranked to wind up the parachute lines, the lower parachute plate moves up closer to the upper parachute plate, and the umbrella ribs unfold; when the parachute lines are released, the lower parachute plate moves down away from the upper parachute plate, and the umbrella ribs close.

[0013] Furthermore, one end of the umbrella column has a vertically arranged adjustment groove, one end of the armrest shell is embedded in the adjustment groove and slides along the adjustment groove, two sets of symmetrically arranged slider groups are fixed on the armrest shell, each slider group includes two sliders, the inner side wall of the adjustment groove has a sliding groove for the sliders to be embedded, and two sets of symmetrically arranged roller groups are rotatably installed on the armrest shell, each roller group includes two rollers, the two sets of slider groups are respectively located between the two corresponding rollers in the same group, and the rollers are embedded in the corresponding sliding grooves.

[0014] Furthermore, the armrest shell is provided with a driving component, which is slidably connected to the armrest shell. One end of the driving component is fixed with a locking pin. The inner wall of the adjustment groove has several locking holes. The driving component is provided with an elastic reset component inside. Under normal conditions, the locking pin is pushed into the locking hole.

[0015] Furthermore, the locking holes are evenly distributed at 5cm intervals along the length of the adjusting groove.

[0016] The beneficial effects of this utility model are:

[0017] This utility model has good operational versatility. Compared with the prior art, this utility model separates the crank handle and the armrest shell assembly, which effectively avoids the problem that when the armrest shell assembly is pushed to the highest point of the umbrella column and locked, the user needs to open and close the umbrella surface. Shorter users cannot reach the armrest shell assembly, so that users with insufficient height can open the umbrella surface without climbing or using tools.

[0018] Meanwhile, the umbrella cord of this utility model starts from the crank handle, passes through the umbrella column, suspension arm and support arm in sequence, and finally connects to the bottom of the umbrella frame. The route of the umbrella cord avoids the armrest shell, so that the armrest shell is set on the side of the umbrella column close to the center of gravity of the umbrella frame, thereby reducing sliding resistance and making it easier for users to push and pull the armrest shell with less effort, making it more convenient to adjust the angle of the umbrella surface.

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1-2As shown, a zone-controlled parasol includes an umbrella column 1 and an umbrella frame 2. The umbrella column 1 has a sliding arm cover 3, which can be locked at any target position on the umbrella column 1. One end of the arm cover 3 is hinged to a support arm 4. The side of the umbrella frame 2 is fixedly connected to the support arm 4. A suspension arm 5 is hinged to the top of the support arm 4, with one end of the suspension arm 5 hinged to the top of the umbrella column 1. The suspension arm 5 and the support arm 4 form a triangular support structure, enhancing the wind resistance of the umbrella frame 2. A crank handle 6 is installed on the outside of the umbrella column 1, and an umbrella rope 7 is wound around the crank handle 6. The other end of the umbrella rope 7 is fixedly connected to the bottom end of the umbrella frame 2. Next, the paracord 7 is wound up and down via the crank handle 6, driving the umbrella frame 2 to unfold or retract. The umbrella column 1, suspension arm 5, and support arm 4 are hollow inside and each is rotatably equipped with a fixed pulley 8. The paracord 7 starts from the crank handle 6, passes through the fixed pulleys 8 in the umbrella column 1, suspension arm 5, and support arm 4 in sequence, and finally connects to the bottom end of the umbrella frame 2. The crank handle 6 is equipped with a self-locking ratchet mechanism 19 to maintain the winding tension of the paracord 7. Several fixed pulleys 8 are respectively installed at the upper end of the umbrella column 1, both ends of the suspension arm 5, the middle of the support arm 4, and the top of the support arm 4. The middle of the support arm 4 has an opening for the paracord 7 to pass through, and the paracord 7 passes through several fixed pulleys 8 in sequence.

[0030] like Figure 2-7 As shown, the umbrella frame 2 includes an upper umbrella plate body 9, a lower umbrella plate body 10, and multiple umbrella rib structures that are fitted on the upper umbrella plate body 9 and the lower umbrella plate body 10. The upper umbrella plate body 9 is fixedly connected to the support arm 4, and one end of the umbrella rope 7 is connected to the lower umbrella plate body 10.

[0031] When the crank handle 6 winds up the umbrella cord 7, the lower umbrella disc moves up and closer to the upper umbrella disc, and the umbrella ribs unfold. The bottom of the lower umbrella disc body 10 is provided with a limiting protrusion 18. The umbrella cord 7 passes through several fixed pulleys 8 in sequence and finally connects to the limiting protrusion 18. When the umbrella rib structure is fully unfolded, the limiting protrusion 18 is engaged with the upper umbrella disc body 9, and one end of the umbrella cord 7 is fixedly connected to the limiting protrusion 18. When the umbrella cord 7 is released, the lower umbrella disc moves down away from the upper umbrella disc, and the umbrella ribs close.

[0032] One end of the umbrella column 1 has a vertically arranged adjustment groove 11. One end of the armrest shell 3 is embedded in the adjustment groove 11 and slides along the adjustment groove 11. Two sets of symmetrically arranged sliders 12 are fixed on the armrest shell 3. Each set of sliders 12 includes two sliders 12. The inner side wall of the adjustment groove 11 has a sliding groove 13 for the sliders 12 to be embedded. Two sets of symmetrically arranged rollers 14 are rotatably mounted on the armrest shell 3. Each set of rollers 14 includes two rollers 14. The two sets of sliders 12 are respectively located between the two corresponding rollers 14 in the same set. The rollers 14 are embedded in the corresponding sliding grooves 13.

[0033] The armrest shell 3 is equipped with a driving component 15, which is slidably connected to the armrest shell 3. A locking pin 17 is fixed to one end of the driving component 15. The inner wall of the adjustment groove 11 has several locking holes 16, which are evenly distributed at 5cm intervals along the length of the adjustment groove 11. The driving component 15 has an elastic reset component inside. Under normal conditions, pushing the locking pin 17 inserts it into the locking hole 16. Pressing the driving component 15 releases the engagement between the locking pin 17 and the locking hole 16. After sliding the armrest shell 3 to the target position, the driving component 15 is released, and the locking pin 17 automatically locks under the action of the elastic reset component. The angle of the umbrella surface can be adjusted by pushing and pulling the armrest shell 3, which is suitable for different scenario needs.

[0034] The operation method of this utility model is as follows:

[0035] Step 1: Adjust the height of armrest shell 3 (to suit the user's height)

[0036] Unlock armrest shell 3:

[0037] Press the drive component 15 on the armrest housing 3 with one hand to compress the internal elastic reset component (spring), causing the locking pin 17 to disengage from the current locking hole 16.

[0038] Slide to the target position:

[0039] The armrest shell 3 slides up and down along the adjustment groove 11 on the umbrella column 1, the roller 14 rolls in the slide groove 13, and the slider 12 restricts lateral displacement to ensure vertical sliding stability.

[0040] Locking and fixing:

[0041] Release the drive component 15, and the elastic reset component pushes the locking pin 17 to automatically insert into the nearest locking hole 16, thus completing the fixation of the armrest shell 3.

[0042] Step 2: Unfold the umbrella (crank handle 6 and wind up the umbrella lines 7).

[0043] Operation crank 6:

[0044] Rotate the handle 6 outside the umbrella column 1 clockwise to gradually wind up the umbrella rope 7 via the self-locking ratchet mechanism 19.

[0045] Drive the lower parachute disk upward:

[0046] The parachute rope 7 is guided by the fixed pulley 8 inside the parachute column 1, suspension arm 5, and support arm 4, which pulls the lower parachute disc body 10 to move upward towards the parachute disc.

[0047] Umbrella ribs unfold: As the lower umbrella disc moves upward, the umbrella rib structure unfolds outward under the thrust, and the umbrella canopy gradually opens.

[0048] Fully deploy lock:

[0049] When the umbrella ribs are fully extended, the limiting protrusion 18 at the bottom of the lower umbrella plate engages with the upper umbrella plate.

[0050] Self-locking maintenance: The ratchet mechanism automatically locks to prevent the paracord 7 from snapping back, ensuring that the canopy remains open in the wind.

[0051] Umbrella closing operation procedure

[0052] Release the parachute lines 7 (turn crank 6 counterclockwise).

[0053] Release self-lock:

[0054] Press the ratchet release button on crank handle 6 (or pull crank handle 6 outwards) to release the ratchet mechanism from locking the steel cable.

[0055] Turn the crank handle counterclockwise 6:

[0056] Slowly turn the rocker handle 6 counterclockwise to release the parachute lines 7. The lower parachute disc will naturally move downward under its own weight and the elasticity of the parachute ribs.

[0057] As the lower umbrella disc moves downward, the umbrella rib structure folds inward, and the umbrella canopy gradually closes up to a vertical state.

[0058] This utility model has good operational versatility, allowing users with insufficient height to unfold the umbrella without climbing or using tools.

[0059] Meanwhile, the umbrella column, suspension arm, and support arm of this utility model are hollow inside and integrate fixed pulleys. The umbrella rope is guided by several fixed pulleys, and the route of the umbrella rope avoids the handrail shell, so that the handrail shell can be set on the side of the umbrella column close to the center of gravity of the umbrella frame, thereby reducing sliding resistance and making it easier for users to push and pull the handrail shell with less effort, making it more convenient to adjust the angle of the umbrella surface.
