Venetian Blinds. Sunday , May 20th , 2018 - 10:24:40 AM
Vertical blinds use a generally wider slat and one can pull a cord to stack the slats together, to one side, or to separate them in the centre and stack them on each end. The slats can be rotated via a rotating shaft in the upper head rail housing, which runs through independent geared carriers that convert the twisting of a tilt rail to a rotation of each individual slat in synchrony. The original vertical blinds were invented in Kansas City, Missouri by Edward Bopp and Fredrick Bopp, who held the original patent. The company name at the time was Sun Vertical. In the 1960s, the patent and company were sold.
A window blind is a type of window covering. There are many different kinds of window blinds which use a variety of control systems. A typical window blind is made up of several long horizontal or vertical slats of various types of hard material, including wood, plastic or metal which are held together by cords that run through the blind slats. Window blinds can be maneuvered with either a manual or remote control by rotating them from an open position, with slats spaced out, to a closed position where slats overlap and block out most of the light. There are also several types of window coverings, called shades, that use a single piece of soft material instead of slats.
Some types of blinds, such as Holland blinds and woven-wood blinds, have small spaces between the slats. Others, such as pleated shades, have no spaces, because the slats are sewn inside fabric.
