Description

Technical Field

[0001] This utility model relates to the field of pergola technology, and more specifically, to a foldable pergola. Background Technology

[0002] A pergola is an outdoor structure primarily used for sunshade and cooling in the summer. It typically consists of supporting beams and a roof, and can be freestanding or attached to a building. With no walls on four sides, it provides a cool and comfortable resting place.

[0003] Existing pergolas connect the roof and support beams in a fixed manner. The support beams provide support for the roof, while the roof provides shade. However, because the roof is fixed, the area receives no sunlight in winter, which limits the use of such pergolas. They are also difficult to dismantle and require reinstallation later. To address these issues, a solution is proposed below. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a foldable pergola that can fold the sunshade curtain to meet different needs.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A foldable pergola includes a frame with several skeletons evenly arranged on it. The skeletons and the frame slide together. A sunshade curtain is mounted on the skeleton and fixedly connected to the skeleton. One end of the sunshade curtain is fixedly connected to the frame. A movable frame is slidably mounted on the frame and fixedly connected to the other end of the sunshade curtain. Two rotating wheels are mounted on both ends of the frame. Pull ropes are looped around the two rotating wheels. The movable frame is fixed to the pull ropes. A control component is mounted on the frame and drives one of the rotating wheels.

[0007] Preferably, the control component includes a rotating shaft, a mounting box, a worm gear, and a worm. The mounting box is fixed to the side of the bracket. The worm gear is rotatably arranged inside the mounting box, and the worm is rotatably arranged inside the mounting box. The worm gear and the worm mesh with each other. The rotating shaft passes through the mounting box, and the rotating shaft and the mounting box are rotatably engaged. The two ends of the rotating shaft are fixedly connected to the axis of the worm gear and the axis of the rotating wheel, respectively.

[0008] Preferably, the support includes columns and connecting frames. Four columns are provided, all of which are arranged vertically and in a rectangular arrangement in the horizontal direction. The connecting frames are fixed to the top of the columns.

[0009] Preferably, the connecting frame is symmetrically provided with sliding grooves, and a plurality of sliders are uniformly slidably arranged inside the sliding grooves. The sliders are fixedly connected to the two ends of the corresponding skeleton and the two ends of the movable frame.

[0010] Preferably, a support rod is installed in the middle of the connecting frame, the support rod is fixedly connected to the connecting frame, and the two rotating wheels are symmetrically arranged at the bottom of the connecting rod.

[0011] Preferably, the mounting box has a swivel opening on its side, and a handle is provided inside the swivel opening. The handle and the swivel opening are rotatably engaged, and one end of the handle is fixedly connected to one end of the worm gear.

[0012] Preferably, the groove extends through the upper and lower end faces of the connecting frame, and a plurality of limiting blocks are provided at the bottom of the connecting frame, wherein the limiting blocks and the corresponding sliders are fixedly connected.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] I. This solution uses a combination of a frame, a skeleton, and a sunshade curtain to form a pergola. The skeleton secures the sunshade curtain, which in turn blocks sunlight. When it is necessary to fold the curtain for sun exposure, a control component drives a rotating wheel. Since the two rotating wheels taut the pull rope, the rotation of the wheels moves the pull rope, which in turn moves a movable frame. The movable frame then moves one end of the sunshade curtain to the other, thus folding the curtain to allow sunlight to penetrate and meet different needs.

[0015] Second, the worm drives the meshing worm wheels to rotate, which in turn drives the shaft to rotate. The shaft then drives the corresponding rotating wheel to rotate.

[0016] Third, the columns support the connecting frame, which in turn supports the movable frame and the skeleton.

[0017] IV. The slides and sliders are used to connect the skeleton and the movable frame to the connecting frame to prevent separation, and also serve as guides.

[0018] 5. The support rod is used to connect the rotating wheel, and it also supports the frame and the moving frame to prevent the middle of the frame and the moving frame from collapsing.

[0019] 6. The handle facilitates the rotation of the worm gear, extending the lever arm and thus reducing the force required to rotate the worm gear. 7. The limit block prevents the slider and groove from separating. Attached Figure Description

[0028] Example 1:

[0029] Please see Figure 1-7 A foldable pergola includes a support frame 1, which comprises four uprights 12 and a connecting frame 13. The four uprights 12 are vertically arranged and rectangularly aligned horizontally. The connecting frame 13 is rectangular and fixed to the top of the uprights 12, supporting the frame. Several frame members 2 are evenly arranged across the connecting frame 13 and slidably fitted onto the connecting frame 13. A movable frame 4 is provided at one end of each frame member 2, slidably fitted onto the frame member 2. The frame member 2 is equipped with... A sunshade curtain 3 is provided, which is fixedly connected to the frame 2. One end of the sunshade curtain 3 is fixedly connected to the support 1, and the other end of the movable frame 4 is fixedly connected to the sunshade curtain 3. The sunshade curtain 3 is formed by the column 12, the connecting frame 13, the frame 2, the movable frame 4, and the sunshade curtain 3. The sunshade curtain 3 provides shade between the column 12 and the connecting frame 13. The movable frame 4 and the frame 2 fix the sunshade curtain 3 to ensure its wind resistance. The sliding cooperation between the movable frame 4, the frame 2, and the connecting frame 13 can realize the folding of the sunshade curtain 3, thereby meeting different needs inside the support 1.

[0030] The upper surfaces of the two sides of the connecting frame 13 parallel to the support rod 16 are respectively provided with sliding grooves 14. The sliding grooves 14 penetrate the upper and lower surfaces of the connecting frame 13 and are parallel to each other. Several sliders 15 are provided inside the sliding grooves 14. The sliders 15 are fixedly connected to the two ends of the corresponding skeleton 2 and the two ends of the movable frame 4. Several limiting blocks 19 are provided at the bottom of the connecting frame 13. The limiting blocks 19 are fixedly connected to the corresponding sliders 15. The cooperation of the sliding grooves 14 and the sliders 15 is used to limit the skeleton 2 and the movable frame 4, so that the skeleton 2 and the movable frame 4 move along the direction of the sliding grooves 14 to prevent them from falling. At the same time, the cooperation of the sliders 15 and the limiting blocks 19 can prevent the skeleton 2 and the movable frame 4 from separating from the connecting frame 13 and ensure stability.

[0031] A support rod 16 is provided inside the connecting frame 13. The support rod 16 is arranged along the arrangement direction of several skeletons 2. The support rod 16 is fixedly connected to the connecting frame 13. The support rod 16 is used to support the middle of the skeleton 2 and the movable frame 4, so as to avoid deformation of the skeleton 2 and the movable frame 4 due to long-term stress on the middle of the skeleton 2, thus extending the service life. The bottom of the connecting rod has symmetrical and rotating wheels 5. Pull ropes 6 are sleeved on the outside of the two wheels 5. The pull ropes 6 are in a taut state and are looped. The movable frame 4 is fixed on the pull ropes 6.

[0032] By rotating the wheel 5, the pull rope 6 will move. By controlling the rotation direction of the wheel 5, the rotation direction of the pull rope 6 can be controlled, thereby controlling the movement direction of the moving frame 4. By controlling the movement direction of the moving frame 4, the folding or unfolding of the sunshade 3 can be controlled. There is no need to manually push the moving frame 4 back and forth along the direction of the slide 14; simply rotating the wheel 5 is sufficient.

[0033] A control component 7 is installed on the bracket 1. The control component 7 is in transmission cooperation with one of the rotating wheels 5. The control component 7 includes a rotating shaft 8, a mounting box 9, a worm gear 10, and a worm 11. A mounting rod is installed between the two columns 12. The two ends of the mounting rod are fixedly connected to the two columns 12 respectively. The mounting box 9 is fixed on the mounting rod. The worm gear 10 is rotatably arranged inside the mounting box 9. The worm 11 is rotatably arranged inside the mounting box 9. The worm gear 10 and the worm 11 mesh with each other. The rotating shaft 8 passes through the mounting box 9 and is rotatably cooperated with the mounting box 9. The two ends of the rotating shaft 8 are fixedly connected to the axis of the worm gear 10 and the axis of the rotating wheel 5 respectively. A rotating opening 17 is opened on the side of the mounting box 9. A handle 18 is installed inside the rotating opening 17. The handle 18 is rotatably cooperated with the rotating opening 17. One end of the handle 18 is fixedly connected to one end of the worm 11.

[0034] Thanks to the worm gear 10 and worm 11 transmission, which has a self-locking characteristic, the sunshade curtain 3 can effectively prevent movement caused by external factors (such as wind) when it is in any unfolded or folded position, ensuring the stability and safety of the pergola. Even under significant external interference, users do not need to use additional locking devices, making operation more convenient and ensuring the reliability of the pergola structure.

[0035] The addition of the rotating shaft 8 lowers the height of the drive wheel 5, eliminating the need for direct contact with the wheel. The shaft 8 reduces the operating height, making it easier for the user to operate. The meshing of the worm gear 10 and worm 11 converts horizontal rotation to vertical rotation, which is then driven by the handle 18, conforming to the user's habits. Furthermore, the worm gear 10 and worm 11 provide unidirectional drive; only the worm 11 can drive the worm gear 10. External forces cannot directly act on the sunshade 3 to move it, ensuring safety. Simultaneously, the handle 18 extends the user's lever arm. According to mechanical principles, a longer lever arm requires less effort, thus reducing the force required to rotate the worm 11 and making it more labor-saving.

[0036] Working principle:

[0037] In use, the support column 12 raises the height of the connecting frame 13 and supports it, forming the framework of the pergola for human use. The sunshade curtain 3 then blocks sunlight from reaching the top of the frame, creating a complete pergola. When the user needs to fold the sunshade curtain 3, they rotate the worm gear 11 via the handle 18. The worm gear 11 rotates, which in turn drives the worm wheel 10. The worm wheel 10 then drives the fixedly connected rotating shaft 8, which in turn drives the corresponding rotating wheel 5. The two rotating wheels 5 are connected by a pull rope 6. Through the friction between the rotating wheel 5 and the pull rope 6, the rotation of the rotating wheel 5 causes the pull rope 6 to move. The pull rope 6 will move the movable frame 4, which in turn will move one end of the sunshade 3 to the other. When the movable frame 4 contacts the first frame 2, it will push that frame 2 to move synchronously until it contacts all the frames 2, thus fully opening the sunshade 3 to meet different usage needs. When the sunshade 3 needs to be opened, simply turn the handle 18 in the opposite direction. The handle 18, through the cooperation of the worm gear 11, worm wheel 10, rotating shaft 8, rotating wheel 5, and pull rope 6, will move the movable frame 4 in the opposite direction, thus opening the sunshade 3 and shielding the interior of the bracket 1. Users can also lay a waterproof curtain on top of the sunshade 3 according to actual needs. The waterproof curtain can further improve the rainproof effect inside the bracket 1, meeting different user needs and improving overall practicality. At the same time, the rainproof curtain will also protect the sunshade 3, preventing rainwater corrosion and thus extending its service life.
