The Ancient Egyptians are believed to be the first to use tilting and pulley systems into their blinds. Blinds, in those days, were incredibly intricate and these systems made them even more expensive. As a result, only very few people were able to own them. To this day, blinds use complex mechanics within them, but they are now very much commonplace. Blinds provide privacy and block light, and they can be adjusted to give you even more control.
How Does it Work?
While there are many different types of blinds available, they tend to work by having pieces of material either placed vertically or horizontally. They then have various controls to enable people to lift or tilt it. Without that function, they wouldn’t be blinds but they would be simple drapes or curtains.
The two basic functions of blinds, therefore, are tilting and raising with horizontal blinds. With vertical blinds, their two functions are tilting and opening sideways. When fully opened, they let out all the outside light and, when fully closed, they block it off completely. By tilting the individual pieces, people have control not just of the amount of light that comes in, but the direction thereof as well.
Think about what a vertical blind looks like. Usually, it will have a measure track at the top, and the louvers hang down from this. They are interconnected, usually with plastic or PVC string, so that they can operate in a uniform way. Usually, a cord to achieve this hangs on the side of the blinds. With horizontal blinds, there is sometimes also a cord, although a wand is becoming more popular. This also enables you lower and raise the blinds slightly, instead of only being able to have them all the way up or all the way down.
The tilter mechanism allows, as the name suggests, for the tilting of the individual louvres. A geared actuator is used to make sure the blind is placed in the correct position, achieving full privacy. With horizontal blinds, it comes with a cord lock, so that it can stay in a specific position. This is not needed with vertical blinds, however.
Today, all blinds come with those basic functions, regardless of the type of blind someone will choose. However, manufacturers are always looking at ways to improve their products, so they have developed a number of ‘enhancements’. This includes metal or plastic chains, monocommand controls, valance and bottom rail designs, plastic or metal weights, and more. Blinds with enhancements are, naturally, more expensive.
Some people think that, because blinds are so common and they all use virtually the same mechanics, they must also be easy to repair if something goes wrong. This is not true, however. An expert will be able to determine whether it is possible to repair them at all. Most of the time, however, they won’t be and actually present a safety risk. Hence, if something starts to malfunction with your blinds, have them replaced as soon as possible.
