Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window processing, and in particular to a folding component and a folding window. Background Technology
[0002] As an important channel for communication between indoor and outdoor spaces, the way windows open directly affects indoor ventilation, lighting, and space utilization efficiency. Currently, the most common window opening methods on the market are casement and sliding.
[0003] Casement windows typically have their sashes mounted on the frame via hinges, opening to the inside or outside. While this opening method provides a relatively large ventilation area, it has several drawbacks. Firstly, casement windows occupy some indoor or outdoor space when open. For rooms with limited space (such as small bedrooms or bathrooms) or locations with special requirements for the building facade (such as the outer edge of a balcony in a high-rise building), the opening of casement windows can be severely restricted, or even rendered unusable. Secondly, in windy weather, the sashes of casement windows are easily affected by wind pressure, causing them to sway. This not only generates noise but can also damage the structure of the sash and frame, posing a safety hazard.
[0004] Sliding windows open and close by sliding the window sashes left and right or up and down along a track within the window frame. While sliding windows don't take up indoor or outdoor space, their ventilation area is relatively small, generally only about half the window area, which affects indoor ventilation to some extent. Furthermore, the overlapping sections between the window sashes allow dust and debris to accumulate in the tracks over time, causing the sashes to slide slowly, increasing resistance, and affecting normal use. Moreover, sliding windows have relatively poor sealing performance, making them prone to water leakage during rainy weather, affecting the dryness of the indoor environment.
[0005] To overcome the shortcomings of traditional casement and sliding windows, folding windows have emerged on the market. Existing folding windows typically employ complex linkage mechanisms or rope traction systems to achieve the folding and unfolding of the window sash. While folding windows using complex linkage mechanisms can achieve the folding function, the structure of these mechanisms is quite complex, containing multiple components. This not only increases the manufacturing cost of the window but also makes the installation process cumbersome and requires a high level of technical skill from the installers. Furthermore, over long-term use, the complex linkage mechanisms are prone to wear and loosening at various connection points, leading to inflexible window sash movement or even jamming, affecting the normal opening and closing of the window.
[0006] While folding windows using rope traction systems have a relatively simple structure, the ropes are susceptible to stress, wear, and aging during use, leading to decreased strength or even breakage. If the ropes malfunction, the entire folding and unfolding function of the window will fail, and repairing or replacing the ropes will be difficult, requiring the disassembly of numerous components and causing inconvenience to users.
[0007] Therefore, how to solve the above problems is an urgent issue that needs to be addressed. Utility Model Content
[0008] The purpose of this invention is to provide a folding component and a folding window that can solve the problems of limited opening space, complex structure, poor stability and difficult maintenance of window sashes in the prior art, and provide a more optimized solution for the development of folding windows.
[0009] To achieve the above objectives, the present invention provides a folding assembly, which includes a connecting rod disposed between the window frame and the window sash. One end of the connecting rod is rotatably connected to a sliding member that moves within the window frame track, and the other end is rotatably connected to a connecting block fixed on the window sash.
[0010] In the aforementioned folding assembly, the connecting rod is connected to the sliding member via a pin, and the connecting rod rotates relative to the sliding member around the pin axis.
[0011] In the aforementioned folding assembly, the connecting rod is connected to the connecting block via a pin, and the connecting rod rotates relative to the connecting block around the pin's axis.
[0012] The pin connection allows the connecting rod to rotate relative to the sliding member or connecting block around its axis, enabling the window sash to automatically adjust the position and angle of the connecting rod according to changes in the angle with the window frame during folding. During opening, the window sash can smoothly transition from a closed to a fully open state, and folding is also completed smoothly, greatly improving the smoothness of opening and folding, reducing operational resistance, and enhancing the user experience. Furthermore, the pin connection allows the connecting rod to rotate relative to the sliding member or connecting block, enabling the connecting rod to distribute stress through rotation when under load, preventing stress concentration at a single point. This reduces wear and damage to the connection points, extends the service life of the folding assembly, and improves the overall window structure.
[0013] In the aforementioned folding assembly, the sliding component is a pulley system that engages with the top rail of the window frame. The pulley system replaces sliding friction with rolling friction, significantly reducing frictional resistance. When the window sash moves, the pulleys roll within the top rail of the window frame, resulting in a small contact area with the rail and generating far less friction during rolling than during sliding. This allows users to easily push the window sash to open and fold, even if the window sash is large or heavy, improving convenience and comfort. Furthermore, in this embodiment where the top rail is used, the pulleys press against the top rail according to the weight of the window sash. Through the elastic deformation and rolling adjustment of the pulley system itself, the smooth operation of the window sash is ensured, enhancing the stability and reliability of the window sash movement.
[0014] Furthermore, a folding window employing the aforementioned folding components includes a window frame with a top rail, a main window sash and a secondary window sash hinged together within the window frame, the main window sash being connected to the window frame via a pivot hinge, a connecting rod being provided between the window frame and the secondary window sash, one end of the connecting rod being rotatably connected to a sliding element that moves within the top rail of the window frame, and the other end being rotatably connected to a connecting block that is fixed to the secondary window sash.
[0015] This utility model uses a top rail of the window frame in conjunction with a sliding component for movement, but it is not limited to the top rail; it can also be designed with a single bottom rail or a combination of the top and bottom rails.
[0016] The aforementioned folding window has a rotation limiter on the connecting block that corresponds to the connecting rod.
[0017] The aforementioned folding window, wherein the pivot hinge includes a pivot disposed between the main window sash and the window frame, and a main window sash pivot hinge and a window frame pivot hinge that cooperate with the pivot are respectively fixed on the main window sash and the window frame.
[0018] The aforementioned folding window has a connecting body between the main window sash and the secondary window sash. The main window sash and the secondary window sash are respectively hinged to the connecting body. One end of the connecting body is provided with a baffle. The main window sash and the secondary window sash extend out a main baffle and a secondary baffle, respectively, and the main baffle and the secondary baffle correspond to the baffle.
[0019] This utility model's folding window adopts the aforementioned technical solution. The main and secondary window sashes are hinged to form a foldable structure. Both sashes are connected to the window frame via pivot hinges and folding components, achieving the effect of completely folding the window sash to one side of the frame. This overcomes the opening limitations of traditional windows, allowing users to adjust the opening angle according to their needs, freely switching between closed, semi-open, and fully open states, thus improving space utilization. The coordinated design of the top rail and sliding components effectively distributes the force on the window sash, ensuring stability during folding and unfolding, preventing swaying after folding, and adapting to harsh weather conditions.

Detailed Implementation
[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0030] Reference Figure 1 As shown, a folding assembly includes a connecting rod 3 disposed between a window frame 1 and a window sash 2. One end of the connecting rod 3 is rotatably connected to a sliding member 4 that moves within a track in the window frame 1, and the other end is rotatably connected to a connecting block 5 fixed on the window sash 2.
[0031] Reference Figures 1 to 5 As shown, the connecting rod 3 is connected to the sliding member 4 via the first pin 3a, and the connecting rod 3 rotates relative to the sliding member 4 around the axis of the first pin 3a; the connecting rod 3 is connected to the connecting block 5 via the second pin 3b, and the connecting rod 3 rotates relative to the connecting block 5 around the axis of the second pin 3b; the sliding member 4 is a pulley system that cooperates with the track of the window frame 1.
[0032] Reference Figures 2 to 6 The folding window includes a window frame 1 with a top rail 1a. The window frame 1 has a main window sash 7 and a secondary window sash 8 that are hinged to each other. The main window sash 7 is connected to the window frame 1 by a pivot hinge. A connecting rod 3 is provided between the window frame 1 and the secondary window sash 8. One end of the connecting rod 3 is rotatably connected to a sliding member 4 that moves within the top rail 1a of the window frame 1, and the other end is rotatably connected to a connecting block 5 that is fixed to the secondary window sash 8. A rotation limiting member 6 corresponding to the connecting rod 3 is provided on the connecting block 5. The rotation limiting member 6 is a baffle that extends integrally from the connecting block 5.
[0033] See Figure 8 As shown, the pivot hinge includes a pivot 10 disposed between the main window sash 7 and the window frame 1. A main window sash pivot hinge 7b and a window frame pivot hinge 1b are fixed on the main window sash 7 and the window frame 1 respectively, and cooperate with the pivot 10.
[0034] See Figure 6 , Figure 7 As shown, a connecting body 11 is provided between the main window sash 7 and the secondary window sash 8, and the main window sash 7 and the secondary window sash 8 are respectively hinged to the connecting body 11; a limiting member 11a is provided at one end of the connecting body 11, and the main window sash 7 and the secondary window sash 8 respectively extend a main baffle 7a and a secondary baffle 8a, and the main baffle 7a and the secondary baffle 8a are respectively corresponding to the limiting member 11a.
[0035] In the initial state, the main window sash 7 and the secondary window sash 8 are in the folded closed position, tightly fitted together, jointly sealing the opening of the window frame 1. At this time, the connecting rod 3 is in the retracted state, with one end rotatably connected to a sliding member 4 at a specific position within the top rail 1a, and the other end rotatably connected to a connecting block 5 fixed to the secondary window sash 8. Because the window sash is in the folded state, a certain angle is formed between the connecting rod 3 and the window sash 2, and the sliding member 4 is located at the end of the top rail 1a closer to the folded side of the window sash 2. At the same time, the rotation limiter 6 on the connecting block 5 restricts the rotation range of the connecting rod 3, ensuring that the window sash 2 is structurally stable in the folded state and will not accidentally shake or loosen.
[0036] When the folding window needs to be opened, an external force is applied to the window sash 2. Since the main window sash 7 is connected to the window frame 1 via the main window sash hinge 7b, under the action of the force, the main window sash 7 begins to rotate around the axis of the main window sash hinge 7b. As the main window sash 7 rotates, the secondary window sash 8, which is hinged to the main window sash 7, is also driven, and the two window sashes begin to fold. At this time, the connecting block 5, which is fixed at one end of the connecting rod 3 to the secondary window sash 8, moves with the movement of the secondary window sash 8. Since the other end of the connecting rod 3 is rotatably connected to the sliding member 4, and the sliding member 4 is restricted to moving only along the track direction within the top rail 1a, the connecting rod 3 will push the sliding member 4 to slide within the top rail 1a in the direction in which the window sash 2 opens.
[0037] As the window sash 2 continues to unfold, the connecting rod 3 continuously adjusts its angle and position along with the movement of the window sash 2. Because the sliding member 4 slides smoothly within the top rail 1a, it provides stable support and guidance for the connecting rod 3, allowing it to rotate and move smoothly. The rotation limiter 6 on the connecting block 5 restricts the rotation range of the connecting rod 3 relative to the secondary window sash 8, ensuring that the connecting rod 3 always moves within a reasonable angle and preventing excessive rotation or jamming.
[0038] The main window sash 7 and the secondary window sash 8 are fully folded to one side of the window frame 1 via the pivot 10, allowing the window to be fully opened. At this time, the sliding member 4 is located at the end of the top rail 1a, and the rotation limit member 6 on the connecting block 5 limits the connecting rod 3 to a suitable position, ensuring that the window sash 2 can withstand a certain amount of external force, such as wind, in the unfolded state, without automatically closing or deforming. The entire process of folding the window from folding to unfolding is completed. Users can freely adjust the opening angle of the window sash as needed to meet different usage needs such as ventilation and lighting.
[0039] In summary, this utility model has been manufactured into actual samples as described in the specification and figures, and has undergone multiple use tests. The results of these tests demonstrate that this utility model can achieve its intended purpose, and its practical value is undeniable. The embodiments described above are merely illustrative examples of this utility model and are not intended to limit its scope in any way, such as the number of window sashes. Any equivalent embodiments made by those skilled in the art, utilizing the technical content disclosed in this utility model, without departing from the scope of its technical features, and without departing from the technical features of this utility model, shall still fall within the scope of its technical features.
