Description

Turnover side-hung casement hinge

The utility model relates to a kind of frame fan installation accessories of building window, particularly a kind of outer opening flat-open window hinge with turn over function.

At present, domestic construction is changed the glass problem with outer opening flat-open window in order to solve wiping, almost all adopt high pin hinge that sash is installed, high pin hinge open have between sash after-frame fan one can arm is overhanging the space, but that can not stay because the size in space is subjected to sash to protract quantitative limitation accordingly is too big, and the sash surface is again almost perpendicular to indoor, wipes therefore that to change glass very inconvenient, human casualty accident happens occasionally, and becomes people already and expects the problem that solves.

The utility model provides a kind of sash external surface that can make to overturn, wipe and change glass behaviour and do that the activity scope is big, safe and reliable, structural strength is high, the upset casement window hinge of good stability to indoor direction.

The purpose of this utility model is this realization, upset casement window hinge is made up of support arm, frame page or leaf sheet, bearing pin, bearing, guide way, pilot pin etc., support arm one end connects with bearing pin with bearing with frame page or leaf sheet, the other end, frame page or leaf sheet is connected on the window frame, bearing is connected on the sash, be shaped on chute on the guide way, pilot pin can be free to slide in chute, forms slider-crank mechanism.When sash is opened on one side near the window frame parallel sliding, the another side bigger angle of outwards overturning, when being used with other annex, any one fixed angle that can be in the unlatching scope.

Owing to adopt such scheme, the utlity model has following characteristics:

A, sash can overturn one than wide-angle, and the sash external surface is tilted to indoor direction, and guide way makes sash slide near window frame, wipe arm front-extending quantity weak point when changing glass, and scope of activities is big, and is easy to operate, and safety is good.

B, hinge form slider-crank mechanism, and sash is opened rear fulcrum and is firm triangle, and safe in utilization, resisting wind press capacity is good.

C, the turning bigger angle of sash, can with sash dorsad wind introduce indoorly, strengthened the function of use of casement window.

Further specify below in conjunction with accompanying drawing.
