A cantilever is a structure or object that is supported on only one end and appears to suspend in the air with little support. It is a commonly used term in engineering and architecture. When applied to the context of an umbrella, a cantilever umbrella is simply an outdoor umbrella used to provide shade which is attached to a single freestanding pole on only one end (instead of in the center as one is used to seeing).
The usual cantilever umbrella is supported by a strong base and a pole or rod that bends slightly as it reaches upwards. A section of the rod angles over horizontally and is connected above the umbrella in the center. In some cases, the rod will sport an additional attachment that rises above the curved section and then downwards toward the vertical section, creating a triangular shape. This is useful for providing additional stability. There are various other components that might be included, however the essential parts are rods rising from one base, curving, and attaching to the center of an umbrella.
Many of these umbrellas are typically large enough in diameter to provide shade for several chairs and even a small table. It is a popular option for tables because with this style there isn’t a rod protruding from the center which can be obstructing and occupy much desired space. However, a cantilever umbrella can be placed close to the edge of a table, and the umbrella will still provide shade above.
The shape and sizing of a cantilever umbrella can differ, as can their price. The standard size range of large umbrellas such as this are between 9-13 feet (2.74-3.96 m) in diameter, with most falling in the middle at around 10 feet (3.05 m) in diameter. Possible variations of the umbrella’s shape include hexagonal, square, round, and octagonal.
It’s frequently noticed that cantilever umbrellas tend to be present in the homes of people at a certain financial stature. In some instances, cantilever umbrellas can cost as high as $1000 USD, but there are many that are within a more affordable price range of $100-200 USD. This gap in the price occurs depending on where one chooses to shop, and if they decide on purchasing a designer brand or not. Good deals are likely available at inexpensive home improvement stores or at big box stores.
Other variations in the design of a cantilever umbrella is their choice of fabrics. Some of these umbrellas are constructed with materials like linen, while others may prefer polyester fabrics and are therefore less expensive. Colors can vary as well; fabrics might sport only one color, exquisite patterns, or stripes. The material for poles will also have differences. Metal is the preferred choice, but plastic or wood can still be present to form at least part of the pole.
The biggest concern many individuals have about the cantilever umbrella is regarding how sturdy the base is. Most designs are heavy and sound enough so that even in heavy winds, they will not tip over. Some designs rely on filling the base of the umbrella with water to increase the weight. However, this style has many problems because they are difficult to reposition and the water will need to be changed or drained if one wants to place it in storage at season’s end.
