Description

The steel sliding sash

Technical field

The utility model relates to door and window, and particularly protection is with drawing grid formula door and window to make the field.

Background technology

Have now and draw grid formula door, generally many grizzly bars vertically are arranged among the rectangular frame, grizzly bar adopts the movable connection of pull bar do each other.In order to strengthen protective action (as antitheft), also the Sliding fence gate structure is used for window.The standard width of a room in an old-style house less relatively (about 800mm) of general dwelling house door, and the opening of window big (1500mm or bigger), for lateral dimension bigger draw the grid window, it is long to open and close stroke on the one hand, inconvenience; Be not easy on the other hand view and admire extraneous landscape from the window centre position.In addition, the aspect that is slidingly matched of grizzly bar and window frame also exists frictional force bigger, opens and closes inconvenient problem, and lockset automatically butt, close the problem that bothers.

The utility model content

The purpose of this utility model is to provide a kind of steel sliding sash, and when window opening was big, it had the function that opens and closes from the middle part.This purpose is realized by following technical scheme: a kind of steel sliding sash, comprise rectangular frame, vertically be arranged on many grizzly bars in the window frame, and and grizzly bar be hinged, be connected many pull bars between the grizzly bar, it is characterized in that described many grizzly bars are connected to a monolithic window leaf or two fan opposite opened window leaves by pull bar; One side of this monolithic window leaf connects firmly on a column of described rectangular frame, and opposite side is provided with and is used for and another column of window frame lockset of snap close mutually; Two outsides of this opposite opened window leaf connect firmly respectively on two columns of described rectangular frame, and its two inboard is provided with the lockset of mutual snap close.From technique scheme as seen, adopt pull bar in hinged way grizzly bar to be connected to a monolithic window leaf or two fan opposite opened window leaves, and lockset is set at the keying position.When window opening is big (as surpassing 1500mm), two outsides of two fan opposite opened window leaves are fixed on two columns of rectangular frame, and its two inside line is provided with lockset.Window just can be opened from the middle part like this, from middle locking, has realized the function that opens and closes from the window middle part.
