Description

Technical Field

[0001] This utility model relates to the field of folding door technology, and in particular to a hanging folding door. Background Technology

[0002] Sliding folding doors are a common type of architectural door. Their ingenious design, using tracks and folding mechanisms, allows the door to slide to the side, significantly reducing space requirements. This makes them suitable for locations with limited space but requiring a large opening area. Generally, the opening height of a standard folding door is within 4 meters. However, in some architectural designs, to ensure the overall aesthetic appeal of the building facade, extra-high openings are often created. These openings are at least 7 meters high. If designed as fully sliding doors in the conventional way, extremely high demands would be placed on stability and smoothness. Meeting these requirements necessitates the use of higher-specification, higher-quality materials and more complex processes, significantly increasing the overall cost. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a hanging folding door. The split structure design not only satisfies the overall transparent installation effect of the facade of the ultra-high opening, but also effectively reduces the cost increase caused by the ultra-high opening. Overall, it combines practicality, economy and flexibility.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A hanging folding door includes: a top fixing frame for fixing to a wall, a plurality of fixed door panels fixed below the top fixing frame, a crossbeam fixed below each of the fixed door panels, a slide rail frame fixed below the crossbeam frame, and a plurality of folding door panels slidably connected to the slide rail frame. Adjacent folding door panels are hinged to each other. A plurality of adjustment structures are connected between the top fixing frame and the crossbeam frame. The adjustment structures are disposed between two adjacent fixed door panels and are used to adjust the distance between the top fixing frame and the crossbeam frame.

[0006] According to some embodiments of the present invention, the adjustment structure includes a threaded rod and an adjusting nut threadedly connected to the threaded rod. The lower end of the threaded rod is fixed to the top of the crossbeam frame, and the upper end is connected to the top fixing frame. The distance between the top fixing frame and the crossbeam frame can be adjusted by rotating the adjusting nut.

[0007] According to some embodiments of the present invention, the adjustment structure further includes a locking nut disposed on the upper side of the adjusting nut, the locking nut being used to limit the position of the adjusting nut.

[0008] According to some embodiments of the present invention, the fixed door leaf includes a side frame, an upper frame connected to the bottom of the top fixing frame, a lower frame connected to the top of the crossbeam frame, and a glass structure, and the threaded rod passes through the side frame.

[0009] According to some embodiments of the present invention, both the upper frame and the lower frame include a clamping part for clamping the glass structure, a hooking part disposed on the opposite side of the clamping part, and a glass fastener hooked onto the hooking part. The glass fastener and the clamping part cooperate to clamp the glass structure.

[0010] According to some embodiments of the present invention, a secondary frame is further provided between the fixed door leaf and the top fixing frame.

[0022] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0023] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intermediary element (e.g., the third element) between the element and the other element.

[0025] An embodiment of this utility model provides a hanging folding door, such as... Figure 1-6As shown, it includes: a top fixing frame 1 for fixing to the wall, multiple fixed door panels 2 fixed below the top fixing frame 1, a crossbeam frame 3 fixed below each fixed door panel 2, a slide rail frame 4 fixed below the crossbeam frame 3, and multiple folding door panels 5 slidably connected to the slide rail frame 4. Adjacent folding door panels 5 are hinged to each other. Multiple adjustment structures 6 are connected between the top fixing frame 1 and the crossbeam frame 3. The adjustment structures 6 are set between two adjacent fixed door panels 2 and are used to adjust the distance between the top fixing frame 1 and the crossbeam frame 3.

[0026] The fixed connection between the top mounting bracket 1 and the wall provides a stable support foundation for the entire hanging folding door, ensuring that the folding door is ready for installation before installation and improving stability during installation. By setting up a segmented arrangement of the fixed door leaf 2 above the folding door leaf 5, the overall design satisfies the merchant's requirements for a transparent facade while allowing for sliding and folding at the bottom. This segmented arrangement reduces the installation height of the folding door leaf 5, lowering the precision and strength requirements of the folding door and significantly saving production costs. Simultaneously, the crossbeam 3 provides a stable boundary for the folding movement of the folding door leaf 5. The addition of the crossbeam 3 further enhances the overall structural strength of the hanging folding door and provides a reliable installation foundation for the sliding rail frame 4, enabling the sliding rail frame 4 to stably bear the weight and movement of the folding door leaf 5. The folding door leaves 5 within the sliding rail frame 4 are hinged together using hinges and other methods, allowing for flexible spatial transformation during folding and unfolding.

[0027] Furthermore, due to the excessive height, even with a segmented design, the upper part of the fixed door leaf 2 on the crossbeam frame 3 will still experience downward pressure due to gravity. This causes the middle section of the crossbeam frame 3 to bend downwards, resulting in a curved track frame 4 for the lower folding door leaf 5 after installation. The curved track creates significant resistance when the folding door leaf 5 is opened, causing it to be difficult to open and close smoothly. Therefore, multiple adjustment structures 6 are installed between the top fixed frame 1 and the crossbeam frame 3, allowing for flexible multi-stage adjustment of the distance between them. After adjustment, the folding door leaf 5 is installed, ensuring the horizontality of the crossbeam frame 3 and improving the smoothness of the folding door leaf 5's sliding. This segmented structural design not only satisfies the overall transparent installation effect of the ultra-high opening facade but also effectively reduces the increased costs caused by the ultra-high height, making it a door structure that combines practicality, economy, and flexibility.

[0028] In some embodiments, such as Figure 2-3 As shown, the adjustment structure 6 includes a threaded rod 61 and an adjusting nut 62 threadedly connected to the threaded rod 61. The lower end of the threaded rod 61 is fixed to the top of the crossbeam frame 3, and the upper end is connected to the top fixing frame 1. The distance between the top fixing frame 1 and the crossbeam frame 3 can be adjusted by rotating the adjusting nut 62.

[0029] The adjustment structure 6 uses a threaded connection between a threaded rod 61 and an adjusting nut 62. The lower end of the threaded rod 61 is fixed to the top of the crossbeam frame 3, and the upper end is connected to the bottom of the top fixing frame 1. Specifically, it passes through the bottom of the top fixing frame 1 and extends upward. The height distance between the top fixing frame 1 and the crossbeam frame 3 can be flexibly adjusted by rotating the adjusting nut 62, which is at the bottom and abuts against the top fixing frame 1, using an adjustable wrench. Multiple adjustment structures 6 adjust the height of different sections of the crossbeam frame 3 in stages to achieve precise installation and adjustment, ensuring the stability and levelness of the hanging folding door and providing a guarantee for the smooth operation of the folding door leaf 5.

[0030] Furthermore, such as Figure 2 As shown, the adjustment structure 6 also includes a locking nut 63 disposed on the upper side of the adjustment nut 62, which is used to limit the position of the adjustment nut 62.

[0031] The adjusting structure 6 adds a locking nut 63 to the outside of the adjusting nut 62. The locking nut 63 has the opposite spiral direction to the adjusting nut 62, which can prevent the adjusting nut 62 from loosening due to vibration or other external forces during use, and ensure that the adjusted distance remains stable.

[0032] Furthermore, such as Figure 1-4 As shown, the fixed door leaf 2 includes a side frame 21, an upper frame 22 connected to the bottom of the top fixing frame 1, a lower frame 23 connected to the top of the crossbeam frame 3, and a glass structure 24. The threaded rod 61 passes through the side frame 21.

[0033] The fixed door leaf 2 consists of a side frame 21, an upper frame 22, a lower frame 23, and a glass structure 24. The threaded rod 61 passes through the side frame 21. Specifically, it can be inside the side frame 21 of a single fixed door leaf 2, or it can be inside the space enclosed by the two side frames 21 of two adjacent fixed door leaves 2. This design cleverly integrates the threaded rod 61 into the structure of the fixed door leaf 2 without affecting its appearance and function.

[0034] Furthermore, such as Figure 3 As shown, both the upper frame 22 and the lower frame 23 include a clamping part 25 for clamping the glass structure 24, a hooking part 26 provided on the opposite side of the clamping part 25, and a glass fastener 27 hooked on the hooking part 26. The glass fastener 27 and the clamping part 25 work together to clamp the glass structure 24.

[0035] Both the upper frame 22 and the lower frame 23 are equipped with clamping parts 25, hooking parts 26, and glass fasteners 27. The clamping parts 25 are integrated with the upper frame 22 or are designed as a single unit to increase clamping strength. The glass structure 24 is first inserted into the frame and abuts against the side of the clamping parts 25, and then the glass fasteners 27 are fastened into the hooking parts 26, so that the clamping parts 25 and the glass fasteners 27 together clamp the glass structure 24, forming a stable fixing method. The structure of the glass fasteners 27, together with the clamping parts 25, ensures the secure installation of the glass structure 24 and also facilitates the replacement and maintenance of the glass structure 24.

[0036] Furthermore, such as Figure 3 As shown, a sub-frame 11 is also provided between the fixed door leaf 2 and the top fixing frame 1. There are multiple top fixing frames 1, multiple top fixing frames 1 are fixed on the top of the sub-frame 11, and multiple fixed door leaves 2 are fixed on the bottom of the sub-frame 11.

[0037] The top fixing frame 1 is not a one-piece structure, but rather multiple individual frames fixed to the wall. It can be set in different shapes according to different walls, offering high flexibility. The sub-frame 11 connects the individual top fixing frames 1 into one unit, providing a unified installation frame for the hanging folding door. This facilitates the alignment and installation of the door leaf 2, while also enhancing the overall structural strength and stability of the hanging folding door.

[0038] In some embodiments, such as Figure 2 , 4 As shown in Figure 5, the slide rail frame 4 includes a slide rail structure 41 fixed to the bottom of the crossbeam frame 3 and a plurality of hanging pulley structures 42 slidably connected to the slide rail structure 41. The hanging pulley structures 42 are fixed to the top of the folding door leaf 5.

[0039] The folding door panel 5 can slide smoothly within the slide rail via the hanging pulley structure 42, reducing friction with the ground, improving the smoothness of pushing and pulling and the service life of the folding door panel 5, and also making it easier to clean and maintain.

[0040] Furthermore, such as Figure 4 As shown, the slide rail structure 41 includes an upper beam frame 43 connected to the bottom of the crossbeam frame 3 and a slide rail frame 44 with a sliding track fixed inside the upper beam frame 43.

[0041] The upper beam frame 43 provides an installation base for the slide rail frame 44. The slide rail frame 44 contains a sliding track for the hanging pulley structure 42 to slide within. The split design facilitates the installation and maintenance of the slide rail structure 41, allowing different slide rail frames 44 to be used with different pulleys without affecting the overall connection stability. The sliding track provides a stable running path for the hanging pulley structure 42, ensuring that the folding door leaf 5 remains stable during sliding.

[0042] Furthermore, such as Figure 4-6 As shown, the hanging pulley structure 42 includes a first hinge structure 45 for connecting two adjacent folding door panels 5 and a pulley body 46 disposed at the top of the first hinge structure 45. Each pulley body 46 is slidably connected in the slide rail frame 44. Two folding door panels 5 connected to the same first hinge structure 45 are a group, and two adjacent folding door panels 5 between two groups are connected by a second hinge structure 46.

[0043] Because each folding door leaf 5 needs to be slidably connected within the slide rail frame 44 and also fold together, adjacent folding door leaves 5 are connected by a first hinge structure 45. Compared to a system where each door leaf has its own pulley and is then hinged together, the first hinge structure 45 includes not only hinges but also a pulley body 46 at the top of the hinge axis. This structure is more convenient, ensures a firm connection between the door leaves, and simultaneously achieves a sliding connection, improving the overall performance and reliability of the door. Figure 6 As shown, the first hinge structure 45 forms a combination of a set of pulley bodies 46 and two folding door panels 5. To achieve hinged connection without affecting opening and closing, adjacent folding door panels 5 are connected by a second hinge structure 46, such as a hinge mechanism, so that they can be moved away from the slide rail frame 44 when folded, forming a... Figure 6 The folding effect is shown.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
