subject: Mechanism Of Window Blinds [print this page] Blinds were invented by the ancient EgyptiansBlinds were invented by the ancient Egyptians. They had a basic function of tilting using pulleys, and were not commonly used because of their high cost. If you believe that myth, then you need to read this article.
Blinds could only have been invented many years later as they were needed to control entering light. In fact, window blinds were an innovation after curtains. Therefore, unlike beer, blinds cannot draw their roots back to an invention by the ancient Pharaohs and they cannot be blamed for the lost tombs either.
Blinds are generally available in horizontal and vertical designs, called horizontal blinds and vertical blinds thus accommodating the particular requirements of the window or door to be covered. Controls are built in to perform the opening and tilting functions of the modern day blind and are also available in a multitude of colors and sizes to fit all applications. All blinds, regardless of origin, must perform these functions in order to meet the consumer demand and specific requirements. In summary, similar functions are found in all blinds with disregard to their origin. Only the quality of the components will dictate the smoothness of operation and reliability of the blind.
Blinds are a curious machine, however. The basic function of a blind is to block light and provide privacy. To do that, they need to be adjustable. Adjust ability is what makes blinds different. Basic blocking of a window can be done with paper, fabric sheets or other permanent or removable coverings. However, if an occupant wishes to adjust the level of privacy or permit some of the light to enter the room, she can use a blind to cause this effect.
Blinds typically have two methods of adjustment. These are tilt, or rotate, and lift, or traverse. The reason for two words for each of these actions is to distinguish between the actions that cause motion in a horizontal blind or a vertical blind. However, interestingly enough, typical blinds have the same mechanisms to adjust. There is little difference in them.
