Abstract

A louver window is composed of a window frame, a louvre blade and a regulating mechanism. The feature is that the cross section of the louvre blade is shaped like a wing, and the middle part is a column form centre shaft. The length of the cross section of the outdoor side wing is longer than the length of the cross section of the indoor side wing. The main rotary shafts on the two sides of the centre shaft are inserted into the circular holes on the two sides of the window frame. The louvre blade is installed on the window frame. In addition, the louvre blade is connected to be a whole through the auxiliary rotary shafts on the two sides of the indoor side wing of the louvre blade using a connecting body. The starting and stopping of the louvre blade is adjusted by moving the connecting body and utilizing a connector pin and the locating piece arranged at the lower ends of the two sides of the window frame. The louver window of the utility model has the functions of sunshade, light modulation, theft protection, keeping off the rain and ventilation, and it has simple structure and convenient manufacture.

Description

Louver window

The utility model relates to a kind of shutter, belongs to the device that buildings exterior-protected structure opens and closes usefulness.Its composition comprises window frame, louvre blade, governor motion.

Now, have market widely as the shutter of independent forms, its Progress in technique is paid close attention to by people.In the prior art, the patented technology of patent No. ZL92227756.7 discloses a kind of shutter of regulating sunshade, and louvre blade is installed on some the vane frame, transmission mechanism by wheels and connecting rod composition, manually the rotation rocking arm rotates vane frame, thus the keying of adjusting vane; The ZL92229798.3 patent disclosure a kind of shutter that can regulate sunshade automatically, the lower right corner at window is provided with self-checking device, be subjected to the variation of environment temperature and changeable volume by the methyl alcohol in the fluid reservoir, promote rotating mechanism, the angle that makes louvre blade changes and regulates sunshade automatically; The ZL92228941.7 patent disclosure the antitheft shutter of a kind of energy, on window frame, set up some cross bars, and each cross bar just is positioned at each louvre blade first half top, thereby under the keying that does not influence louvre blade, anti-theft feature arranged.

Though the ZL92227756.7 patent has realized the purpose of manual adjustments sunshade, transmission mechanism complexity, loaded down with trivial details; The ZL92229798.3 patent can be regulated sunshade automatically according to environment temperature, but environment temperature and intensity of sunlight, direction of illumination and angle are not the same thing, does not more reflect wish and other condition of user; Though the ZL92228941.7 patent has anti-theft feature, establish the segment space that one group of cross bar has occupied window frame in addition.Thereby, the shutter of prior art or increase complicated transmission mechanism, or the segment space that occupies window frame reaches and regulates shading or antitheft purpose, and the function that can well breathe freely when not having rainproof and louvre blade to close.

The utility model is intended to overcome the deficiencies in the prior art and a kind of sunshade light modulation of providing, antitheft, rainproof, airing function are had both and shutter simple in structure.

The purpose of this utility model is achieved in that in the window frame both sides and is respectively equipped with the equidistant circular hole of a row that pitch-row is less than the width of louvre blade.The cross section of louvre blade is aliform, and the middle part, cross section is thicker, can be circle, ellipse, rectangle or rhombus, becomes the column axis of louvre blade; The both sides wing length in louvre blade cross section differs, and grows up in long by indoor wing by outdoor wing.Main rotary shaft is established at the two ends of column axis, inserts respectively in the circular hole of window frame both sides, and shutter is installed on the window frame.Establish auxiliary rotating shaft in the both sides of louvre blade indoor wing end in addition, insert respectively in the circular hole of the other bar shaped connected body in window frame both sides, make all louvre blades connect to integral body.The pitch-row of circular hole equates with the pitch-row of the set circular hole in window frame both sides on the connected body.The connected body lower end is established a locating hole in addition, and is provided with the keeper of porous in lower end, window frame both sides, utilizes mobilizable latch to insert in the locating hole of certain hole of keeper and connected body lower end, can regulate the location to the keying of louvre blade.Connected body, latch, keeper have been formed governor motion of the present utility model, and selecting some holes of keeper is tunable optical.

Shutter of the present utility model has disposed governor motion, has the function of sunshade, light modulation; The axis of louvre blade is a cylinder, and high mechanical strength is arranged, thereby antitheft function is arranged, and can select the cylinder of different thicknesses according to the antitheft degree of reliability for use; The width of louvre blade (aliform cross-sectional length) is greater than the spacing of window frame two mother rib lateral rotundums, when louvre blade in the raw the time, overlapped therebetween, and because wing cross section, outside is grown up long in wing cross section, indoor, the louvre blade outdoor section has a down dip, indoor section upwarps, thereby the function in the rainproof inlet chamber is arranged; Louvre blade leaves the gap in the raw the time between sheet, thereby the function that makes room ventilation ventilative is arranged again.

Shutter of the present utility model because well-designed to structure, shape, make it have both sunshade light modulation, antitheft, rainproof and ventilative function, and governor motion is simple and direct, and light modulation is easy and simple to handle; Whole shutter is simple, manufactures conveniently, and cost is low.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a shutter;

Fig. 2 is the shutter lateral view.

Below in conjunction with embodiment the utility model is done a progressive statement.

Shutter of the present utility model is indoor view as shown in Figure 1, and louvre blade (2) is opening.The both sides of window frame (1) respectively are provided with the equidistant circular hole of a row, and its pitch-row is less than the width of louvre blade (2).The two ends of the column axis (8) of louvre blade (2) respectively are provided with a main rotary shaft (6), insert respectively in the hole of window frame (1) both sides.Be provided with auxiliary rotating shaft (7) in the both sides of the indoor of louvre blade (2) wing end in addition, insert respectively in the connected body (3), all louvre blades (2) are connected into an integral body.Connected body (3) is two strip members, is located at respectively by the both sides of window frame (1).Union body (3) is also respectively established the equidistant circular hole of a row, is used to insert auxiliary rotating shaft (7), and the pitch-row of the pitch-row of circular hole and window frame (1) both sides equates.In the lower end of each connected body (3) locating hole is arranged respectively, and be provided with keeper (4) at window frame (1) two side bottom, (5) are latches.For the different opening degrees of louvre blade (2), the track that the last locating hole of connected body (3) moves is an arc, thereby the circular hole on the keeper (4) must be by this arc shooting.

Figure (2) is the shutter lateral view.The figure shows louvre blade (2) in the raw, its cross section is an aliform, and middle circular portion is column axis (8), and the broken circle in it is main rotary shaft (6), and the broken circle of indoor wing end is auxiliary rotating shaft (7).
