Soft elastic blades and sunshading transparent blinds of the blades

Abstract

In order to solves the contradiction between sunshading and lighting, the present invention provides one new kind of soft elastic blade and blinds of the blades and corresponding parts or devices, and the blinds have high lightning effect while sunshading. The blade may be produced in different sizes and is easy to replace. The blinds have the features of good sunshading effect, wide application range, high safety performance, good decorating effect, etc. and is suitable for public places, household, etc.

Description

technical field [0001] The invention relates to a venetian blind, in particular to a venetian blind which is composed of soft elastic blades and can greatly improve perspective and lighting effects while shading the sun. Background technique [0002] Existing venetian blinds have two types: horizontal arrangement and vertical arrangement. Because the materials, shapes, arrangement and connection methods of the blades are different, the effect achieved and the application place are also quite different. [0003] In the existing horizontally arranged venetian blinds, the blades are mostly cross-armed on the ladder ropes, and are arranged horizontally and parallel to each other between the upper and lower frames. The blades mainly rely on the ladder ropes and drawstrings to realize positioning and rotation. . In order to suppress the deformation of the blade, it is usually made of hard material, and its cross section is mostly arc-shaped or streamlined, or it has a correspondi...

Problems solved by technology

[0007] 2. There are unsafe factors

But the above-mentioned see-through space is quite limited, because the see-through direction provided by the space between the blades is perpendicular to the plane of the window and the ground symmetric direction with the sunlight incident direction, so when the sunlight is incident from the left side of the window , people can only look to the right side of the window, and the reverse is the same; that is, only when the blades are inclined at a certain angle, the observer can obtain a certain visual space at the position facing the space between the blades

Otherwise, the line of sight is blocked and it is impossible to look over

[0013] 2. The line of sight can only extend vertically, which does not conform to people's usual habit of waiting and watching

However, its field of view can only extend longitudinally, that is, its line of sight can only extend up and down along the space between the blades at an angle of -45° to the vertical plane (A). It is impossible to obtain a continuous visual space in its horizontal direction, so the visual space provided by the venetian blinds arranged in this way is vertically narrow and long, and people's sight is blocked in the horizontal direction, which does not conform to the usual habit of watching

[0015] 3. The line of sight of the moving observer is constantly cut by the leaves, which affects the perspective effect

[0016] Usually, the moving direction of the observer is perpendicular to the longitudinal axis of the blade. For example, industries that need to show their service activities to the outside world or want to attract the attention of passers-by, such as shop windows and commodities, are all committed to obtaining or providing a better However, due to the movement of the observer, it can only obtain a relatively good perspective ratio in a small area in an instant, but cannot form a continuous horizontal imaging, and no matter where the observer is Or, the perspective rate of the observation area will gradually decrease as it moves, until it is completely covered, and the perspective rate of the next area will gradually increase, and then gradually weaken

Therefore, the line of sight is constantly cut by each blade plane, which affects the perspective effect

[0017] In summary, the reason why the prior art has the above-mentioned deficiencies is that it is restricted by the structure, material, shape, arrangement and connection mode of the main components of the blinds, which reflect the ubiquitous problems to varying degrees. Contradictory relationship between shading, perspective, and daylighting that affect each other or cannot take into account each other
