Foldable umbrella

An umbrella is without discussion,a very suitable object for rainy days. Unlike a raincoat, an umbrella can provide a larger space deprived of rain which makes it a better shelter because it is easier to move under an umbrella. It is also ideal for warm but rainy weather. Whereas the concept of umbrella itself is a design,foldable umbrellas carry this concept to a whole new level of usefulness. This function makes it easier to carry an umbrella because it fits in your bag ,sometimes even in your pocket. Since you can always carry it with you,you can always be prepared for an unexpected rain situation. Having a small umbrella makes it easier to fit in crowded places such as public transportation. It is because of these benefits that people prefer to use foldable umbrellas rahter than the big ones.

Reading the previous paragraph,you may think that a foldable umbrella is a brilliant design. But if you try to use it in a stormy day you will see that it is nothing but useless. The mecanism that allows a foldable umbrella to fold is in fact the ablitiy of the metal bars (the ones which give the umbrella it's shape) to bend.This ablitiy makes the bars vulnerable against the wind. Because of this weakened structure the umbrella keeps folding backwards and as a result you get wet. Besides it is not very easy for corpulant people to fit under small umbrellas. So there are several conditions where a foldable umbrella is not a useful object.
