Description

The present invention relates to a stopper for an aluminum sash window.

At present, aluminum sash windows are widely used in buildings, but in consideration of safety when the windows are opened, iron and aluminum grids are often provided outside the windows. Although it can prevent children from falling down, it has safety problems such as being unable to escape when a fire breaks out and firefighters cannot enter. Moreover, many luxury homes have restrictions on the convention that the appearance of the building must be maintained, so that the windows may not be provided with iron bars. Therefore, usually, a stopper is attached to the aluminum sash window to limit the distance for opening the outer window sash, thereby preventing the child from falling from the window that has been opened too much. The “aluminum sash window stopper” disclosed in Taiwan Patent No. I286586 is composed of a pedestal, at least one lock member, and at least one elastic locking member. Among them, the pedestal body is provided with a storage portion for storing the elastic locking member, and the lock member is attached to one side of the storage portion. It is possible to lock the elastic locking member that has been raised from the above or accommodated in the accommodating portion. When the elastic locking member is raised from inside the housing part, the distance that the window sash can be opened is limited, and when the elastic locking member is housed in the housing part, the distance that the window sash can be opened is not limited. The function of the window sash is the same.

However, it is possible to prevent the child from falling from the window or entering the thief by raising the locking member of the stopper from the housing and further locking it, but when an emergency such as a fire occurs Problems arise. That is, when an emergency situation occurs, the locking member must be accommodated in the accommodating portion and the window sash must be fully opened. However, since the locking member is controlled by the locking member, the locking member is accommodated. The lock member must be unlocked one by one with the key, both when it is raised from the inside and when it is housed in the housing portion, which is inconvenient in use. Moreover, the key must be hidden so that the child cannot easily release the lock member. However, the key may not be found in an emergency situation, and there is a risk.
