A pulley.
The blinds that cover windows are often operated by a pulley. In order to pull up the blinds, one needs to pull down on rope attached to a pulley that changes the direction of the applied force so that a downward pull causes an upward push of the blinds. Although the window blinds are on a pulley system the window itself is not an example of a pulley.

Pulleys are really useful at times because of all the things they can help you with. For example, window blinds. Have you ever even thought about the way the blinds in your window work? They work with pulleys! The small pulley in your window folds the blinds and pulls them up. There are pulleys in elevators, cranes, lifts, wells, dumbwaiters, even tape rolls.
You probably wont. Chances are, if your window doesn't go up and down right, you have a broken pulley in the window regulator assembly. This is common and requires the replacement of the window regulator.
