TECH ARTICLE NO. 13| How does Casement Window Friction Hinges work?
The friction stay hinge for external casement windows is a very common window hardware, which is used in various engineering projects around the world. However, most people are still not clear about the composition and the properities of friction stay hinges. This article will describe the composition of the friction hinge and the analysis of each part in friction hinges. Hope it can be helpful.
Firstly, let's talk about in details of the composition of the casement window friction stay hinges.
Friction hinges are usually made of stainless steel and generally include bottom groove, sliders, support arms and rivets. As shown in the figure, the support arm 1 is used to install the window sash and play a supporting role. The support arm 2, 3 and 4 is directly linked to the slider and acts as a track that carries the slider's movement. The thickness and assembly structure of the support arms are the direct factors that affects the bearing capacity of the window friction stay hinges. The bottom groove are mounted on the window frame profile, so that the bottom groove and support arms can connect the sash and the window frame together.
As shown in the figure, as a high-quality window brace, the slider is the part that plays the role of moving guide. Its requirements must meet the characteristics of smooth opening, rust and corrosion resistance. The following are the sliders used in the curtain wall window friction hinges of Sihai Hardware Factory. The nylon-clad stainless steel material makes the window braces have a longer service life and smoother use.
The rivets at the joint are the key to the firmness of a window friction hinge. Rivets must be round and smooth. There should be no riveting cracks, and the two ends of the rivet should not be higher than the outer surface of the assembly. When a high-quality window friction hinge is opened, the connection should not be loose.
In general, the composition of a casement window friction hinge is composed of five important parts: the bottom groove, the slider, the support arm and the rivet. Each plays a vital role. The above article can also tell you more details to judge whether a window friction hinge is of high quality.
