Extra-heavy casement window sliding support hinge

Abstract

The invention discloses an extra-heavy casement window sliding support hinge which comprises a sliding rail, a first sliding block, a second sliding block, a movable support gasket and a plurality of support cantilevers which are assembled. One end of a second short support cantilever is hinged to the second sliding block and then is placed into the sliding rail, a first short support cantilever and the support cantilevers are correspondingly hinged to the first sliding block and the movable support gasket and are placed into the sliding rail, one end of a long support cantilever is hinged with the sidling rail, the middle of the long support cantilever is respectively hinged to the other ends of the second short support cantilever and the support cantilevers, the other end of the long support cantilever is hinged to the middle of a top support cantilever, one end of the top support cantilever is hinged to the first short support cantilever, and a reinforced support cantilever is respectively hinged to the middles of the top support cantilever and the support cantilevers. The bearing capacity of the sliding support hinge is improved by the movable support gasket, abrasion of the sliding support hinge is avoided, the sliding support hinge are easily and freely opened and closed and are durable, the tail end of the top support cantilever cannot droop or dip downwards due to the gravity action of a sash, and accordingly, untight closing of a casement window is avoided.

Description

technical field [0001] The invention relates to a sliding stay hinge. Especially a special sliding stay hinge suitable for extra wide and extra heavy casement windows. Background technique [0002] The sliding stay hinge for casement windows is a kind of sliding stay hinge assembled from slide rails, sliders, top support cantilever, short support cantilever, support cantilever and long support cantilever: the short support cantilever, support cantilever and slider are hinged accordingly Then install the slide rail; the short support cantilever, the top support cantilever, the support cantilever, the long support cantilever, the long support cantilever and the slide rail are also hinged accordingly to form a movement mechanism. One end of the slide rail is equipped with a guide top angle, which guides the opening and closing of the hinge. A pair of sliding braces are installed on the casement window. When the window sash is pushed, the window sash transmits force to the mov...

Problems solved by technology

[0003] This kind of sliding stay is mainly suitable for small and medium-sized windows with a sash width less than 900mm. If this sliding stay hinge is installed on an ultra-wide and overweight casement window, the following will occur: Some problems: 1. When the window sash is opened or closed, the support cantilever of the sliding stay hinge installed at the bottom of the window sash, especially the short support cantilever, bends or tilts downward under the action of gravity of the window sash, causing the short support cantilever to contact the window frame or slide rail. Contact friction, as the number of opening and closing increases, the opening and closing of the window sash will become more and more difficult, and eventually it will be damaged due to too much resistance to open and close or wear; 2. When the window sash is closed, the cantilever on the top supports the gravity of the window Downward bending or tilting, causing the sash to sag and not close tightly

3. Since there is no restricting device, it will be dangerous when the opening position of the large window sash is greater than the length of the human arm
