Umbrellas

An umbrella is a portable canopy designed to provide protection from rain or sunlight. It typically consists of a fabric or treated material canopy mounted on a collapsible framework of ribs, carried by a shaft and ending in a handle. When open, the ribs extend the canopy; when closed, they fold around the shaft for compact storage.

Umbrellas have ancient origins as sunshades in various civilizations, including Egypt, Mesopotamia, and China, where they symbolized status and power. The use of umbrellas for rain protection began to spread in Europe by the 16th or 17th century. In the modern era, improvements to materials and mechanisms led to lighter, more durable rain umbrellas and to the development of folding designs.

Design and materials: The canopy is usually made of treated fabric such as polyester, nylon, or coated cotton; earlier versions used silk or linen. Ribs have evolved from wood and whalebone to steel and, later, aluminum or fiberglass. The shaft can be straight or telescoping, and many umbrellas include a mechanism for automatic opening and closing or for wind resistance.

Variants and use: Folding or pocket umbrellas are designed for portability, while larger models offer greater coverage. A related device, the parasol, is used mainly for sun protection and is typically not waterproof. Umbrellas also appear as fashion accessories and promotional items, and contemporary designs often incorporate features such as ergonomic handles, vented canopies, and reinforced frames for durability.

In contemporary life, umbrellas remain a common, widely manufactured item available in a range of styles, sizes, and prices, reflecting both practical needs and cultural trends.
