Polygonal combined umbrella

The utility model relates to a multilateral composite umbrella, which is characterized in that a plurality of umbrellas can be combined and the umbrella face is not easy to be blown over. Take the quadrilateral umbrella for example; the umbrella face is stretched on the quadrilateral skeleton which is formed by four mutually connected bars through a connection ring and is able to fold. The four connection rings are connected with a sliding sleeve in the middle of the umbrella with a pull rope. The umbrella handle extends from the sliding sleeve and supports the umbrella face upward. The sliding sleeve and the pull rope pull the umbrella face downward. The interactive force between the pull rope and the umbrella keep the skeleton in the balance and stretch the umbrella face into smooth condition. The structure is very suitable for producing larger umbrellas; in addition, the periphery of the umbrella is provided with a zipper which can be used alone or combined with other umbrellas. Further, the umbrellas can be arrayed and assembled into geometric patterns according to requirements, thus not only the shade effect is improved, but also the decoration effect is enhanced. The utility model has the advantages of good application prospect at commercial booths, cultural activities, and tourist spots.
