The conventional umbrellas are used to against sun and rain, however, there are some inherent problems that are difficult to resolve for years. When using an umbrella in a windy day, the umbrella can easily flip inside out under a certain level of wind such 30 mph wind. This is partially because the canopy is so large that when wind blows from inside of the umbrella, the umbrella flips inside out. In a windy and rainy day, the result is the same as no umbrella is used.
The present invention intends to provide an umbrella which is designed to against wind so as to keep the canopy from flipping inside out.
The present invention relates to an umbrella and comprises a shaft having a top cap connected to the top end thereof. A runner is movably mounted to the shaft. Multiple rib units and multiple stretchers are pivotably connected to the top cap and the runner. The rib units each have a first rib, a second rib and a third rib. The first, second and third ribs are pivotably connected in sequence. A canopy is mounted to the rib units. The second ribs each have a first connection portion on one end thereof. The first connection portion has a seat which is connected to a link unit. The link unit has a joint which is connected to the third rib which has a positioning member to position the joint. The third rib and the joint are connected with each other to bear wind force applied to the second rib and the third rib, such that the second and third ribs do not deform.
Preferably, the joints each include multiple links which are located side by side. Two respective ends of each of the links are connected to each other. The links expand laterally to form a main part. One end of the main part is bent to form one or multiple openings.
Preferably, each of the joints is a sleeve connected to one end of the link unit. The sleeve is mounted to the third rib corresponding thereto. An open end of the sleeve is pivotably connected to the link unit.
Preferably, each of the joints is a bent end on one end of the link unit.
Preferably, the first ribs each have the first end connected to the top cap, and the second end of each first rib has a second connection portion. The second ribs each have a third connection portion on one end thereof, and the second connection portion is overlapped and connected to the third connection portion so as to form a support point.
Preferably, the umbrella is a foldable umbrella or a single shaft umbrella.
Specifically, the third rib and the joint are connected with each other to bear wind force applied to the second rib and the third rib, such that the second and third ribs do not deform when strong wind is applied to the umbrella. Therefore, the structural strength is enhanced and resolves problems of deformation of the ribs happened to the multiple-stage foldable umbrellas.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to
The umbrella 10 comprises a shaft 2 having a top cap 3 connected to the top end thereof, and a runner 4 is movably mounted to the shaft 2. Multiple rib units 1 and multiple stretchers 5 are pivotably connected to the top cap 3 and the runner 4. The number of the rib units 1 and stretchers 5 is the same. The rib units 1 each have a first rib 11, a second rib 12 and a third rib 13. The first, second and third ribs 11, 12, 13 are pivotably connected in sequence. The length of each of the first, second and third ribs 11, 12, 13 may be different. A canopy 6 mounted to the rib units 1. The second ribs 12 each have a first connection portion 121 on one end thereof, and the first connection portion 121 is connected to the third rib 13. A protrusion 123 is formed at the connection between the first connection portion 121 and the third rib 13 so as to support one end of the third rib 13. The first connection portion 121 has a seat 8 which is connected to a link unit 7. The link unit 7 has a joint 71 which is connected to the third rib 13 which has a positioning member 131 so as to position the joint 71. The third rib 13 and the joint 71 are connected with each other to bear wind force applied to the second rib 12 and the third rib 13, such that the second and third ribs 12, 13 do not deform when wind is applied to the umbrella. The specific structure enhances the structural strength of the umbrella.
It is noted that the first ribs 11 each have the first end connected to the top cap 3, and the second end of each first rib 11 has a second connection portion 111. The second ribs 12 each have a third connection portion 122 on one end thereof, and the second connection portion 111 is overlapped and connected to the third connection portion 122 so as to form a support point.
Each of the joints 71 is a bent end on one end of the link unit 7, this is just an example and does not limited to the present invention, the bent end forms a hole, as shown in
