Description

Technical Field

[0001] The utility model relates to an umbrella, in particular to an umbrella with an adjustable umbrella surface size, belonging to the technical field of umbrellas. Background Art

[0002] An umbrella is a tool for sheltering from the rain, usually made of oil paper, oilcloth or plastic cloth. Throughout the year, when the rainy season comes, it occasionally rains, and when it rains, people usually use umbrellas to keep out the rain. The materials used to make umbrellas usually include stretchable fabrics and other materials that can be used as frames and winding threads.

[0003] Chinese patent application publication number CN221729916U discloses an umbrella with adjustable canopy size. This invention incorporates multiple first-number ribs and multiple movable frames. When the first slider is moved upward, the movable frames are moved downward, allowing the movable frames to sequentially enter the interior of the telescopic fabric and the second buckle, thereby extending the telescopic fabric. This extension of the fabric effectively increases the canopy size.

[0004] Although the solution of the above patent can adjust the size of the umbrella surface according to the needs of use, the umbrella with adjustable umbrella surface size in the above patent is not convenient to reinforce the adjustment position after the adjustment is completed. Due to its insufficient protection measures, it will be deformed when encountering strong winds, making it less stable when in use. Therefore, an umbrella with adjustable umbrella surface size is proposed herein. Utility Model Content
