Market umbrellas are an older style of umbrella. This type of umbrella usually has a wooden pole, and some models are offset or are made to be adjustable so that users alter the shaded area. Market umbrellas are generally opened or closed by a single pulley or two-pulley system. They originated in Europe, and their name comes from their frequent use in outdoor markets and cafes.
A crank umbrella is also called a patio umbrella. These umbrellas are also sometimes tilted or adjustable. Traditionally though, the crank or patio umbrella has a hollow aluminum pole and a hand crank for opening and closing.
In recent years, the line between these styles of umbrella has blurred. For example, it is not unusual now to find market umbrellas equipped with hand cranks.
