Three-dimensional multifunctional side-hung and suspended friction stay

Abstract

A three-dimensional multifunctional side-hung and suspended friction stay comprises an on-frame installation rod used for being installed on a window frame and a supporting arm used for being installed on a window sash, a multi-connecting rod cantilever used for opening or closing the window sash is connected between the on-frame installation rod and the supporting arm, and a locating device used for limiting the opening angle of the window sash, a closing device capable of preventing shaking between the window frame and the window sash when the friction stay is closed and a window sash falling prevention device preventing the window sash from falling down are arranged between the on-frame installation rod and the multi-connecting rod cantilever. The three-dimensional multifunctional side-hung and suspended friction stay is reasonable and simple in structure and can be located and limited in the half-open mode or in the fixed-angle open mode of any angle through cooperation among the locating device, the closing device and the window sash falling prevention device, a whole window can keep stable and does not shake when the window sash is opened or closed, and the window sash can be prevented from falling down in time even if the window sash or connection components of the window sash are damaged after being used for a long time. Thus, the three-dimensional multifunctional friction stay can realize multiple functions and multi-direction stabilization and reinforcement.

Description

technical field [0001] The invention relates to architectural door and window hardware, in particular to a 3D multi-functional sliding brace that can be opened and suspended. Background technique [0002] Doors and windows are an indispensable and important part of a building. The building not only bears the impact from the environment, such as wind pressure and rain and snow, but also bears the gravity of the switch and its own weight in use. With the increasing development of our country's economy and the continuous improvement of people's living standards, people's requirements for housing are getting higher and higher, and the requirements for the installation of housing doors and windows are naturally also increasing. When the traditional hinge is used on the casement and suspended window, its own impact on the environment and the gravity bearing capacity of the switch and self-weight during use are low. When it is applied, it must be installed with a retainer. Therefor...

Problems solved by technology

[0004] At present, the horizontal opening and suspension sliding stays on the market can only realize the positioning restrictions of the two states of fully open and fully closed, and cannot realize the positioning restrictions of the half-open and fixed-angle slightly open states, which leads to its functional and stable use. The sex does not meet the requirements of people's use

Especially in severe weather with strong wind and heavy rain, it is difficult to effectively guarantee the stability of the fan frame, and it may even cause damage to the window fan, causing danger.

In addition, when the existing sliding brace is closed, it needs to be positioned and fixed by the corner structure, otherwise it will affect the sealing of the sash and the stability of the entire door and window

In the prior art, the wrap angle is stamped and formed by a single part and then riveted on the fixed rod, which is not easy to process, and the angle positioning effect is poor, and it is also limited to the fixed installation of the C-shaped groove, and the wall thickness of the C-shaped groove is limited. It cannot be integrally formed, and even if it is formed, its strength cannot meet the requirements for use

Since the material thickness of the C-shaped groove fixing rod is about 0.9-1.5mm, it is formed by cold pressing. The groove wall is too thin, it is easy to cause the window sash to fall, and the product stability is not high

In addition, the C-shaped groove is easy to accumulate dust during installation or trial, which increases friction and reduces the stability of the window

In addition, the window sash and connecting parts may be damaged after a period of use, especially in a windy and rainy environment, it is more likely to be worn or damaged. When these connecting parts are damaged, the window sash may fall off the window frame

Especially the window sashes of high-rise buildings, once they fall down, it will not only damage the objects downstairs, but more dangerously, it will hurt pedestrians, and even endanger the lives of pedestrians
