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.
Window blinds can be manually drawn using a cord, or automated through motorization. Controls for motorized blinds can be from a wall switch or keypad, remote control, or computer, eliminating the need for cords and allowing control of otherwise inaccessible windows. A number of modern homes are integrating blind control with central C-Bus solutions. This control provides ease-of-use and is effective for controlling blind operation to reduce heat loss during winter or minimize heat from the sun during summer.
The term window blinds can also be used to describe window coverings generically—in this context window blinds include almost every type of window covering, i.e. shutters, roller blinds, cellular shades (also called honeycomb shades), wood blinds, roman blinds and of course, standard vertical and horizontal blinds. In the United Kingdom, awnings are sometimes called blinds or shades.
