Another purpose of masking device is to prevent that people from can directly see the inside of building.In this case, adjust masking device so that the visibility in building is minimum, and the people that the light amount that enters simultaneously is suitable in the building also is important.
Therefore, proved that it is favourable adopting tiltable lath to design masking device.Lath can tilt, thereby can satisfy the demand of printing opacity and visibility.Lath tilts manyly more, and it covers just many more.Also proved in masking device and to have used the favourable part of lath to be that the inclination of lath can produce the light regulating effect, therefore can control, the light that penetrates by lath to ceiling or down to the floor.
Under the situation of covering, lath can be risen, make that the opening of building reality is unsheltered.
The known method that lath in several inclination venetian shutters is arranged, for example, known rotation by bar comes inclined slab.Lath can be tilted to position contacting each other, and stop the further inclination of single lath thus.This known devices has following shortcoming, after lath reaches maximum angle, when bar further rotates, because user's applied force does not have inclined slab, but absorbed by the actual bindiny mechanism between bar and the lath on the other hand, being connected of bar and lath may be ruptured.In most cases, these bindiny mechanisms can not absorb this power in design, and therefore these connections can be damaged usually.
Do not have under the situation about rupturing owing to the further rotation of bar in the connection between bar and the lath, rotatory force is continued inclined slab by transmission.Owing to reached its maximum angle at this position lath, it is forced to further inclination, causes the actual lath or the damage of lath place device.
In addition, because from architectural viewpoint, light has become the important element in the building design, so there was such trend in recent years, the structure of new building is to front with big glass and window.The building of multilayer and individual layer is not always the case.Therefore, produced the demand to venetian shutter, the people in building, venetian shutter is soft and is easy to regulate.
Therefore, these masking devices or venetian shutter are arranged in the opening of various buildings, and comprising big window fronts, venetian shutter is placed on the inboard and the outside of window fronts with can covering several floors.
In addition, need venetian shutter in lucarne, these windows tilt to place along the roof usually.These described windows are placed to such an extent that make that the user is difficult to get at usually, therefore, the inclination of the lath in the venetian shutter of these windows are occurred in place away from window.
Therefore, need a kind of solution that be used for tilting the lath of the venetian shutter that the user can not get at.
There is difference significantly in everyone to the demand and everyone the needed shield coverage of light amount and radiation direction, and may take place repeatedly to change within one day.And the user of venetian shutter may have different height, especially under adult and child's situation.Therefore, need the solution of the lath in a kind of venetian shutter that tilts for a long time, the control device that wherein is used to tilt can be placed at various height according to user's different heights.
Therefore, in U.S. Pat 2,557, disclose a kind of venetian blind system in 978, it is placed in the actual window.By the displacement ratchet lath is tilted, move up and down in the short groove of ratchet in being fixedly set in window frame, this ratchet is connected with a rope.The length of groove depends on the size of the angle that lath can tilt.Groove is fixedly installed in the window frame of venetian shutter one side, makes regulating system to adapt to the higher or shorter user who wants inclined slab.In addition, the position of groove is limited in the length range of venetian shutter, so it can not be arranged on the opening below of building fully.
For known venetian shutter, common problem is, the user is used for the device of inclined slab and can not freely be provided with to adapt to user's different heights, perhaps can not freely be provided with to adjust the position of venetian shutter with respect to the user.
