Multifunctional slip supporting hinge

Abstract

The present invention discloses a multifunctional slide supporting hinge. It includes a slideway, a slide block mounted in said slideway groove, a first bracket arm for fixing on the window sash, a second bracket arm whose one end is hinged on the middle portion of said first bracket arm. Besides, it also includes a third bracket arm and a fourth bracket arm which are hinged with the slide block,in the described slideway interior a spring leaf is fixedly mounted in the end portion close to the slideway, between the described spring leaft and first slide block a second slide block is mounted in the described slideway and can be slidden in the slideway, and another end of the described second bracket arm is hinged on said second slide block. Besides, said invention also provides its workingprinciple and operation method.

Description

technical field [0001] The invention relates to a sliding stay for a window, which can meet the opening angle requirement when escaping through a window in addition to being used as a normal sliding stay hinge within a normal opening angle. Background technique [0002] A sliding stay hinge used on windows is composed of slide rails, sliders and several support cantilever hinges. The opening angle is changed by sliding the slider in the slide rail. However, the current sliding stay hinge which is hinged by a slide rail, a slide block and a plurality of support cantilever arms can only rotate relative to the slide rail and cannot slide because one of the long support cantilever arms is directly hinged on the slide rail. Can make window open to maximum design opening angle like this, although have satisfied the requirement of normal use, people can't go in and out from window, but be unfavorable for escaping and rescue from window when dangers such as fire occur. At the same...

Problems solved by technology

However, the current sliding stay hinge which is hinged by a slide rail, a slide block and a plurality of support cantilever arms can only rotate relative to the slide rail and cannot slide because one of the long support cantilever arms is directly hinged on the slide rail. In this way, the window can be opened to the maximum design opening angle. Although the requirements for normal use are met, people cannot enter and exit through the window, which is not conducive to escape and rescue through the window in the event of fire and other dangers.

At the same time, since the slider cannot be positioned at a certain position when sliding, the initial opening of the sash cannot be within a safe limit.
