Abstract

The utility model relates to a semi-automatic folding window sash, which belongs to the design field of building doors and windows. The utility model is characterized in that two window sashes are respectively provided with a shaft; the lower end of the shaft is provided with a fan-shaped gear; the fan-shaped gear is engaged with a tooth arm; the other end of the tooth arm is engaged with a handle gear. The handle gear is rocked, a fan-shaped shaft can rotate through the linear gliding movement of the tooth arm, and one end of a parallelogram window sash frame which is fixed to the shaft of the window sash generates deformation (the window sash is folded into a shape like the Chinese character 'yi' when closed, and in a shape like the Chinese character 'chuan' after opened) to play a role of opening and closing the window sash. By making no use of a catch with a bolt, the semi-automatic folding window sash is very firm. After aluminum alloy and plastic steel windows are pulled to open, one half of a window is blocked, and the semi-automatic folding window sash changes that the effects of visual angle, lighting and ventilation are influenced. The utility model is easy to wipe glass for sanitation, and is hidden into a wall body and can not be exposed after folded.

Description

Semi-automatic superimposed sash

The semi-automatic superimposed sash of the utility model relates to the switching mode of house window sash, and particularly wooden to tradition, current trend aluminium alloys, plastic-steel sash open and close the improvement of mode, belong to the building doors and windows design field.

The house sash is from wooden, metal, and even plastic-steel switching mode has two kinds: a kind of is the hand switch formula, and the sash outer sleeping with eyes half-closed in back that is opened is shone and drenched with rain, if forget and hang up window catch, is easily damaged by strong wind, closes window simultaneously and requires great effort, as the wooden sash of tradition.Another kind is the formula of manually operating a switch, and after sash was drawn back, two fan sash overlaped, and have blocked half window standard width of a room in an old-style house, influence the visual angle, and daylighting and ventilation effect are as aluminium alloys, the plastic-steel sash of current trend.

The utility model is to develop its advantage: do not push away not open with latch after closing on the basis of superimposed sash of fully-automatic metal and semi-automatic folding sash; Very infirm after the unlatching with window catch.Sash after the unlatching is overlapped in " river " font plant body of wall and does not expose, and the shield window standard width of a room in an old-style house does not influence visual angle, daylighting and ventilation effect.

The purpose of this utility model is to realize like this (see Fig. 1, Fig. 2): 2. 3. two fan sash respectively have an axle, a sector gear is equipped with in the axle lower end 1., 5. sector gear meshes with the tooth arm, 4. the tooth arm other end meshes with the handle gear again, shake the handle gear by the motion of tooth arm line sliding, the fan axle can be executed and change 0 °-88 °.Two fan tape spool sash utilization parallelogram 6. principle connect with other sash, and when the fan axle rotates then parallelogram window sash frame generation deformation: sash builds up " one " font when closing, and opens the back sash and builds up " river " font.For opening and closing conveniently, universal pulley is equipped with in the sash lower end.Because the window inside casing is equipped with the flannelette bar, is embedded with the rubber bar on the glass edge, and is tightly seamless after closing.Sash is overlapped into " river " font and only ties up space, window both sides and do not expose, and both attractive in appearancely is difficult for crashing through glass, conveniently again is easy to smear glass and does health, is convenient to indoor dress Adjustable screen window net simultaneously, and wall is adorned the metal anti-theft net outward.

That the utility model can be attached to is wooden, change the switching mode of former sash on the metal, plastic-steel window frame, also can produce the window of different size according to the building construction needs.

The utility model concrete structure is by Fig. 1, Fig. 2 explanation.

Claims

1, semi-automatic superimposed sash technical characterictic is: two fan sash respectively have an axle, a sector gear is equipped with in the lower end of axle, sector gear meshes with the tooth arm, the tooth arm other end again with the handle gears engaged, shake the handle gear, just can rotate by tooth arm line sliding motion fan axle, an end is fixed on the parallelogram window sash frame generation deformation on the sash axle, plays the sash effect that opens and closes.

2, semi-automatic superimposed sash according to claim 1, its sash switching mode are that the utilization parallelogram principle is closed (stretching, extension) or opened (superimposed).
