Umbrella
Modern use

National Umbrella Day is held on 10 February each year around the world.

The pocket (foldable) umbrella was invented in Uraiújfalu (Hungary) by the Balogh brothers, whose patent request was admitted in 1923 by the Royal Notary Public of Szombathely. Later on their patent was also approved in Austria, Germany, Belgium, France, Poland, Great Britain and the United States.

In 1928, Hans Haupt's pocket umbrellas appeared. In Vienna in 1928, Slawa Horowitz, a student studying sculpture at the Akademie der Bildenden Kunste Wien (Academy of Fine Arts), developed a prototype for an improved compact foldable umbrella for which she received a patent on 19 September 1929. The umbrella was called "Flirt" and manufactured by the Austrian company " Brüder Wüster " and their German associates " Kortenbach & Rauh ". In Germany, the small foldable umbrellas were produced by the company "Knirps", which became a synonym in the German language for small foldable umbrellas in general.In 1969, Bradford E Phillips, the owner of Totes Incorporated of Loveland, Ohio, obtained a patent for his "working folding umbrella".

Umbrellas have also been fashioned into hats as early as 1880 and at least as recently as 1987.

Golf umbrellas, one of the largest sizes in common use, are typically around 62 inches (157 cm) across but can range anywhere from 60 to 70 inches (150 to 180 cm).

Transparent umbrellas, often made with plastic or composite materials, were invented in 1958 by Mitsuo Sudou. The transparent umbrellas were popularized as fashion items during the 1964 Tokyo Olympics. The production had since been relocated to China and other Asian countries and has become ubiquitous on Japanese streets due to its affordability, aesthetics, and ease of access.

Umbrellas are now a consumer product with a large global market. As of 2008, most umbrellas worldwide are made in China, mostly in the Guangdong, Fujian and Zhejiang provinces. The city of Shangyu alone had more than a thousand umbrella factories. In the US alone, about 33 million umbrellas, worth $348 million, are sold each year.

Umbrellas continue to be actively developed. In the US, so many umbrella-related patents are being filed that the U.S. Patent Office employs four full-time examiners to assess them. As of 2008, the office registered 3000 active patents on umbrella-related inventions. Nonetheless, Totes, the largest American umbrella producer, has stopped accepting unsolicited proposals. Its director of umbrella development was reported as saying that while umbrellas are so ordinary that everyone thinks about them, "it's difficult to come up with an umbrella idea that hasn’t already been done."

While the predominant canopy shape of an umbrella is round, canopy shapes have been streamlined to improve aerodynamic response to wind. Examples include the stealth-shaped canopy of Rizotti (1996), scoop-shaped canopy of Lisciandro (2004), and teardrop-shaped canopies of Hollinger (2004).

In 2005 Gerwin Hoogendoorn, a Dutch industrial design student of the Delft University of Technology in the Netherlands, invented an aerodynamically streamlined storm umbrella (with a similar shape as a stealth plane) which can withstand wind force 10 (winds of up to 100 km/h or 70 mp/h) and won't turn inside-out like a regular umbrella as well as being equipped with so-called ‘eye savers’ which protect others from being accidentally wounded by the tips. Hoogendoorn's storm umbrella was nominated for and won several design awards and was featured on Good Morning America. The umbrella is sold in Europe as the Senz umbrella and is sold under license by Totes in the United States.

Alan Kaufman's "Nubrella" and Greg Brebner's "Blunt" are other contemporary designs.
