Description

Technical Field

[0001] This utility model relates to an opening system that controls the opening and closing of a window sash via a connecting rope. Background Technology

[0002] In the fields of architectural design and indoor environmental control, windows, as key components for regulating indoor light, ventilation, and views, have always been a focus of attention for designers and users in terms of ease of operation and efficiency. Traditionally, the opening and closing of windows has mainly relied on manual operation. Although this method can meet basic needs in small residences or low-rise buildings, the limitations of manual window systems are becoming increasingly apparent as building size and complexity increase.

[0003] Existing manual window opening systems, especially in large public buildings, high-rise buildings, or special environments, often face challenges such as complex structures, inconvenient operation, and high costs. These systems typically require additional auxiliary devices, such as window openers, to help users overcome gravity or resistance and achieve smooth window opening and closing. While the introduction of window openers improves operational convenience to some extent, it also significantly increases costs. The structural design of window openers themselves is often quite complex, including components such as rollers, drive shafts, locking hooks, and ratchet wheels. The precision machining and assembly of these components not only increases production costs but also increases the difficulty and expense of subsequent maintenance, as illustrated by a window opening system disclosed in CN215056453U.

[0004] Therefore, the market urgently needs a window system that can maintain cost-effectiveness while simplifying the structure. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide an opening system that controls the opening and closing of a window sash by means of a connecting rope.

[0006] The technical solution of this utility model is: an opening system for controlling the opening and closing of a window sash by means of a connecting rope, which includes a window frame and a window sash hinged in the window frame, an assist rod installed between the window frame and the window sash, and also includes a window frame wheel frame, a window sash wheel frame, a connecting rope and a winch. The window frame wheel frame and the window sash wheel frame are respectively fixed on the window frame and the window sash, one end of the connecting rope is fixed on the window frame or the window frame wheel frame, and the other end of the connecting rope is connected to the winch. The connecting rope passes around the window frame wheel frame and the window sash wheel frame.

[0007] Furthermore, the connecting rope is a non-metallic rope.

[0008] Furthermore, a roller for the connecting rope is installed on the sash wheel frame, and one or two rollers for the connecting rope are installed on the frame wheel frame.

[0009] Furthermore, it also includes a corner pulley around which the connecting rope passes.

[0010] Furthermore, the number of window frames can be single or multiple.

[0011] The advantages of the window sash opening and closing control system provided by this utility model are as follows: This system can realize the opening and closing control of the window sash through the connecting rope, window frame wheel frame, window sash wheel frame and winch. Compared with the traditional window opening system, it greatly simplifies the structure, reduces the use of complex mechanical parts, and thus effectively reduces production costs. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model;

[0013] Figure 2 This is a schematic diagram showing the usage state of this utility model when the window sash is open;

[0014] Figure 3 This is a schematic diagram showing the usage state of this utility model when the window sash is closed;

[0015] Figure 4 This is a schematic diagram showing the connection between the window frame wheel bracket, the window sash wheel bracket, and the connecting rope of this utility model.

[0016] In the diagram: 1—window frame, 2—window sash, 3—assist rod, 4—window frame wheel frame, 5—window sash wheel frame, 6—connecting rope, 7—winch, 8—roller, 9—corner wheel. Detailed Implementation

[0017] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0018] like Figure 1 — Figure 4 As shown, an opening system for controlling the opening and closing of a window sash via a connecting rope includes a window frame 1 and a window sash 2 hinged within the window frame 1, with an assist rod 3 installed between the window frame 1 and the window sash 2. The system also includes a window frame wheel bracket 4, a window sash wheel bracket 5, a connecting rope 6, and a winch 7. The window frame wheel bracket 4 and the window sash wheel bracket 5 are respectively fixed to the window frame 1 and the window sash 2. One end of the connecting rope 6 is fixed to the window frame 1 or the window frame wheel bracket 4, and the other end of the connecting rope 6 is connected to the winch 7. The connecting rope 6 passes around the window frame wheel bracket 4 and the window sash wheel bracket 5.

[0019] The connecting rope 6 is a non-metallic rope, preferably a braided rope, which is low in cost.

[0020] like Figure 4 As shown, a roller 8 is installed on the window sash wheel bracket 5 for the connecting rope 6 to pass through, and one or two rollers 8 are installed on the window frame wheel bracket 4 for the connecting rope 6 to pass through. Figure 4As shown, the number of rollers 8 on the window frame wheel bracket 4 is preferably two.

[0021] like Figure 1 As shown, an opening system for controlling the opening and closing of a window sash via a connecting rope also includes a corner pulley 9 around which the connecting rope 6 passes. The corner pulley 9 can be fixed to the wall to facilitate the turning of the connecting rope 6.

[0022] The number of window frames 1 can be single or multiple, and the number of window frames 1 is equal to the number of window sashes 2. For example... Figure 2 , Figure 3 As shown, when there are multiple window frames 1, the window sashes 2 can be "connected" together using connecting ropes 6. Figure 2 As shown, when there are multiple window frames 1, one end of the connecting rope 6 is fixed to the window frame wheel 4. When there is only one window frame 1, one end of the connecting rope 6 can be fixed to either the window frame 1 or the window frame wheel 4.

[0023] When window sash 2 is a top-hung window, the assist rod 3 is a gas spring. When window sash 2 is a bottom-hung window, the assist rod 3 is a damping rod.

[0024] When window sash 2 needs to be closed, the connecting rope 6 can be wound into the winch 7 (which has a rotatable handle) by cranking the winch 7, thus closing window sash 2. For normal ventilation and lighting, the winch 7 can be cranked in the opposite direction to open window sash 2. In case of emergency smoke extraction, the release handle of the winch 7 can be manually moved or pulled, releasing the connecting rope 6. Through the action of the lever 3, the connected window sash 2 can be quickly opened. The winch 7 is preferably a manual winch, but an electric winch can also be used.

[0025] This system can control the opening and closing of window sash 2 by connecting rope 6, window frame wheel bracket 4, window sash wheel bracket 5, and winch 7. Compared with traditional window opening systems, it greatly simplifies the structure, reduces the use of complex mechanical parts, and thus effectively reduces production costs.

[0026] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
