Description

Multi-folding umbrella structure

Technical Field

The utility model belongs to the technical field of an umbrella, specifically indicate a many formula parachute kit structures, with can have light weight, short and small effect after rolling over to go out to carry, and provide quick and stable umbrella opening and receive the umbrella action, can effectively produce the supporting effect simultaneously, the rib unit can not influenced by umbrella cloth and the incurving when guaranteeing to open the umbrella, and can ensure that umbrella cloth can be by normal upset, and the unlikely phenomenon that turns over.

Background

An umbrella is a tool for shielding rain, snow and a cool environment. The umbrella mainly comprises a central rod with a handle at the bottom end, an upper nest connected to the top of the central rod, a push sleeve with a lower nest and slidably sleeved on the central rod, a plurality of umbrella rib units pivoted between the upper nest and the lower nest and umbrella cloth combined on the outer side surface of the umbrella rib units. When the conventional umbrella is not used and folded, the umbrella cloth of the umbrella is folded from top to bottom inwards, so that a user can still be splashed onto the body by rainwater on the surface of the umbrella cloth at the moment of entering a vehicle or a room, and related manufacturers develop the umbrella capable of being folded reversely;

the rib unit of the prior reverse folding umbrella is mainly formed by pivoting a main rib pivoted on an upper nest by two sections of folding ribs, and an auxiliary rib pivoted on a lower nest of a push sleeve is used for pushing and connecting the folding rib adjacent to the upper nest in the main rib and driving the other folding rib to be reversely folded, so that when the push sleeve is operated to move between an umbrella opening position and an umbrella closing position of a middle rod, the purposes of opening and closing the umbrella can be achieved. In order to further reduce the storage volume of the umbrella for the convenience of carrying by users, the current industry designs multi-fold umbrellas, such as up to four-fold umbrellas;

however, the four-fold umbrella frame unit of the known four-fold umbrella faces some problems in use, for example, the four-fold structure of the four-fold umbrella frame unit makes the frame unit have three folded parts, so that the structural strength of the whole frame unit is weakened, but because the frame unit needs to support the whole umbrella cloth and is also the main part bearing the maximum wind resistance, the folding ribs different from the upper nest in the frame unit have insufficient supporting force, so that the pivot joints of the folded parts of the frame unit often become the central point damaged by strong wind, once the umbrella cloth turns over due to the instant wind force, the frame unit is inevitably damaged and deformed, and the umbrella cloth cannot turn over normally when the umbrella is opened, thereby affecting the smoothness and stability of operation, and how to solve these problems is a person in the industry and users at present.

Accordingly, the present inventors have made extensive studies on the problems of the conventional multi-folding umbrella in use, and have made many years of research, development and manufacturing experience in the related industries to actively seek a solution, and have made continuous and diligent research and trial work to successfully develop a multi-folding umbrella structure, which can overcome the inconvenience and trouble of the conventional umbrella frame unit due to insufficient supporting force.
