Safety escape window

Abstract

The invention relates to a safety escape window which comprises a window frame and glass arranged on the window frame; in the window frame, the side frame of a rotating shaft is hinged with a wall, and a master long pole is provided with two hinge mechanisms; one end of the master long pole is hinged with the lower end of the side frame of the rotating shaft, and the other end thereof is provided with a locking device; the master long pole is connected with a plurality of slave poles through short poles; the upper end of each slave pole is connected with the master long pole through a cable-stayed lock; and the upper end of the side frame of the rotating shaft is provided with a baffle. In the safety escape window, because the baffle on the side frame of the rotating shaft is matched with the locking device in the window frame, the glass, the master long pole and the side frame of the rotating shaft are fixed together, so that window can serve as a common window in normal life; in case of fire and other dangerous circumstances, a motor on the locking device is started or the glass is broken, so that the master long pole and the side frame of the rotating shaft are separated, the master long pole and the slave poles are scattered under the action of gravity and become the handspikes of a ladder, the short poles become horizontal levers, the window frame becomes the safety ladder, so as to realize the function of helping disaster victims to escape.

Description

technical field [0001] The invention relates to a window, in particular to a safety escape window which can be used as an ordinary window in normal life and can be used as an escape safety ladder in times of crisis such as fire. Background technique [0002] According to the characteristics of the fire and the investigation of the cause of death of the people who died in the fire, it was found that most of the people who died in the fire died of suffocation due to inhalation of poisonous gas and dust. Proceeding from this point, the most urgent solution to how to reduce fire casualties is to do everything possible to evacuate the affected people quickly, that is, to allow them to leave the dangerous environment (dense smoke and fire) in time. That is, transfer the victims to a safe place, that is, a place where there is no smoke or fire. For housing design and construction, it is often by widening the width of the corridor and increasing the number of corridors. But this w...

But this will reduce the applicable area of ​​the house and affect the interests of the builder

And because the corridors are generally designed inside the house, when the house catches fire, the corridors will soon be filled with thick smoke, which brings great hidden dangers to the escape of personnel.

At present, there are also some safety escape windows that can be used as escape ladders in critical moments such as fires. For example, the Chinese patent No. CN93202405. Composed of ladder-shaped metal windows, the escape ladder can be formed by combining multiple pieces of ladder-shaped metal windows pivotally connected in times of crisis. The disadvantage is that it needs to be installed outside ordinary windows, which is inconvenient to install and increases construction costs. Affects the sight of people in the building
