An umbrella is a device designed to protect against sun or rain showers. To fully understand how an umbrella works, you have to be familiar with the different parts of the umbrella and what function each one performs to get the umbrella open and ready to create shade against rain or sun. Read below to learn about the parts of an umbrella and what they stand for.
The Canopy
This is the most recognizable part of an umbrella as it is the fabric that shields an individual from rain or sun. The canopy can be made of several materials, such as polythene or nylon, which happens to be the most common. The canopy can also come in any design of choice, either plain, clear, or a pattern design.
The Shaft
The shaft is the core of an umbrella as it is where all the other parts of the umbrella meet to carry out their function. It is the rod in the center that holds every other part together including the handle. It can be made of plastic, metal, fiberglass, or wood.
The Ribs
These are the strips that run underneath the canopy to connect it to the shaft and give it shape. It makes up the entire frame and curve of the canopy. It can be made of fiberglass, metal, or plastic.
The Stretcher
The stretcher is the metal, fiberglass, or plastic material that connects the ribs and the runner of an umbrella. It contributes greatly to the smooth operation of an umbrella.
The Runner
This is another part of the umbrella that the shaft accommodates, which plays a great part in the operation of an umbrella and how it works. This is the part that you slide up when you want to open your umbrella and slide down when you need to collapse the umbrella. When you slide the runner up, the stretcher extends, and that causes the ribs to spread out under the canopy. When you decide to collapse the umbrella, the runner comes all the way down with the stretcher folded flat against the shaft.
The Springs
This is the part that locks the umbrella into position, either opened or closed. The first part is situated along with the button of the shaft, while the other is located just below the point where the stretchers fully extend.
How the Part Operates The Umbrella
First, you press the spring to unlock the umbrella from its closed position, the runner then slides up, causing the stretcher to extend as it does. This, in turn, forces the ribs to take on a spherical shape to stretch the canopy to the right frame to protect against sun or rain. Once you push the runner up until the stretcher fully extends, the spring will lock it in place. After the rain has stopped, you’d want to close your umbrella. The process is a reverse of the opening process, which starts with a press on the spring to free up the runner to slide down. As the runner goes down, the stretcher and ribs fall back flat and gather around the shaft and the string locks it in position. This gives room for easy storage after the rain is down.
