The term 'Umbrella Parts' refers to the components of an umbrella. The most important part is the RIBS, which are the metal or plastic rods that form the frame of the umbrella and provide support for the fabric canopy. The RIBS are connected to a handle, which is used to open and close the umbrella. Other parts include the tip, which is the pointed end of the umbrella, and the stretchers, which are the pieces of metal or plastic that connect the RIBS to the handle.
