Design of the Opening Method of Top-Hung Windows
Manual Opening
For top-hung windows of ordinary height, a handle can be installed below the window sash. The handle usually adopts an ergonomic design, which is convenient for users to grip and apply force. By rotating the handle, the window sash is driven to rotate around the hinge at the top, realizing the opening and closing of the window. This method is simple and straightforward, with a relatively low cost, and is suitable for most residential houses and small buildings. For top-hung windows of ordinary height, manual opening is quite convenient. Moreover, if the window is at a relatively high position, an automatic opening and closing method can be adopted, that is, using a remote control for operation, which is more convenient. Besides, some awning windows are originally installed at a high position, making it impossible for people to open and close them manually.
To facilitate operation, a friction hinge can be installed between the window sash and the window frame. The friction hinge can provide appropriate resistance, keeping the window sash in a fixed position after opening, and preventing it from swinging randomly due to wind or other external forces. At the same time, it can also play a buffering role when closing, reducing the collision between the window sash and the window frame and extending the service life of the window.
Electric Opening
For top-hung windows at a relatively high position or of a large size, manual opening may be inconvenient. In this case, an electric opening method can be adopted. An electric push rod or motor is installed on the window sash, and the opening and closing of the window are controlled through a remote control or a switch on the wall. The electric opening method is more convenient and can achieve remote control, which is especially suitable for high windows in large commercial buildings or residential houses.
To ensure safety, electric top-hung windows are usually equipped with a limit device to prevent the window sash from being opened or closed excessively, causing damage. At the same time, a safety sensor can also be installed. When the window sash encounters an obstacle during the closing process, it can automatically stop and reopen to avoid injuring people or damaging items.
Design of the Opening Method of Bottom-Hung Windows
Manual Inner Opening
Bottom-hung windows generally adopt the inner opening method, and a handle is installed at the bottom of the window sash. When opening, hold the handle and lift it upward, and the window sash rotates inward around the hinge at the bottom. This opening method is easy to operate, and the inward-opening window sash does not occupy outdoor space, making it suitable for places with limited space.
To ensure the tightness of the window sash after closing, a sealing rubber strip can be installed between the window frame and the window sash. The rubber strip should have good elasticity and weather resistance, and can form a tight seal when the window sash is closed, preventing rainwater, dust, and air from penetrating. With manual inner opening, such awning windows can be installed at a relatively low position and can be opened and closed by hand. This kind of awning window with manual opening and closing is relatively cheaper compared to those with remote control and intelligent functions. If it is an ordinary courtyard or a countryside-style villa, this kind of awning window can be installed.
Linkage Opening
For some large bottom-hung windows or a combination of continuous windows, a linkage opening method can be designed. By installing a linkage device, such as a connecting rod or a transmission mechanism, between multiple window sashes, one handle can control the opening and closing of multiple window sashes simultaneously. This method can improve the ventilation efficiency, and it is also convenient to operate, making the opening of the windows more orderly and aesthetically pleasing. For large combined windows, the opening and closing of multiple window sashes can be designed, and it is more convenient to use remote control. Besides, when there are many windows and doors, it may be impossible to close them all in time when it rains. In this case, using the remote control method can close the windows more quickly.
Design of the Opening Method of Center-Hung Windows
Manual Operation
The manual opening of center-hung windows usually involves installing a handle in the middle of the window sash. When opening, turn the handle, and the window sash is driven to rotate around the central rotating shaft through the transmission device. Since the opening angle of center-hung windows is relatively large, to facilitate controlling the position of the window sash, multiple positioning slots can be set on the window frame. After the window sash is opened, it can be stuck in different slots to achieve different degrees of ventilation. Manual operation is very convenient, and center-hung windows with manual operation are suitable for installation at a relatively low position because if you want to close the window manually, it should be at a low position where you can reach it.
To ensure the stability of the window sash during the opening and closing process, guide wheels or sliders can be installed on the upper and lower edges of the window sash. The guide wheels or sliders cooperate with the guide rails on the window frame, enabling the window sash to move smoothly and reducing shaking and friction. Also, cotton strips can be installed on the edges of the frame to reduce the friction caused by opening and closing the window.
Hydraulic-Assisted Opening
For large center-hung windows, in order to reduce the force required for manual opening, a hydraulic-assisted device can be adopted. The hydraulic-assisted system consists of a hydraulic cylinder, an oil pump, and a control valve, etc. When turning the handle, the oil pump delivers hydraulic oil into the hydraulic cylinder, pushing the piston to move, thus driving the window sash to open. The hydraulic-assisted opening method can make the opening of the window sash easier and smoother, and it is suitable for places with high requirements for the opening force. For large center-hung windows, adopting the hydraulic-assisted opening method is more convenient for opening.
When designing the opening method of awning windows in Australia, factors such as the local climate conditions, architectural style, and users’ usage requirements also need to be considered to ensure that the designed windows are both beautiful and practical. At the same time, it is necessary to comply with the local building regulations and safety standards in Australia to ensure the safety and reliability of the windows.
