[Solution] The ultra-short multi-stage folding umbrella has a center rod 1, a roller, and a rib frame 5. The center rod 1 is formed by six short tubes that are fitted together, and the roller includes an upper roller 2 and a lower roller 3. The upper roller 2 is fixed to the top end of the center rod 1, and the lower roller 3 slides on the short tube of the first section of the center rod 1 to control the opening and closing of the ribs 6. The rib frame 5 is formed by combining a number of ribs 6, and each rib 6 is made up of an auxiliary rib 6a, a main rib 6b, a second rib 6c, a third rib 6d, a fourth rib 6e and a tail rib 6f. One end of the main rib 6b is pivoted to the upper roller 2, and one end of the auxiliary rib 6a is pivoted to the lower roller 3. By increasing the number of short tube sections of the center rod 1 to six, the length of the umbrella after it is stored is shortened, and the ribs 6 utilize joints offset to the side to reduce the volume after the umbrella is stored without increasing the thickness, and when the entire ribs 6 are folded, they form a very thin and slim shape.

Description

[Technical field]

[0001] This invention relates to the field of umbrella equipment technology, in particular to an ultra-short multi-stage folding umbrella. [Background technology]

[0002] An umbrella is one of the essential tools in daily life. It provides shade and UV protection on sunny days, and protection from wind and rain on rainy days. In recent years, more and more people are carrying umbrellas when they go out, but if the umbrella is not lightweight and easy to carry, it can become a burden when you go out.

[0003] Conventional umbrella ribs are designed to fold together when stored, and as the ribs overlap when folded, they have a certain thickness. Furthermore, when stored, the ribs overlap and interfere with each other, making the umbrella bulky after folding, and making it less lightweight and portable. In addition, conventional folding umbrellas use a three or five-section center pole, which means that the umbrella does not shorten in length when folded up, taking up a large amount of space when folded up, and making it inconvenient to put into a portable bag. To solve the above problems, an ultra-short multi-folding umbrella with excellent portability is provided. Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned prior art has the disadvantages that the ribs of the umbrella are folded together when stored, making the umbrella thick and bulky, and thus not being lightweight and portable enough.

[0014] (One embodiment) In order to clearly explain the embodiments of the present invention or the technical solutions in the prior art, the embodiments or the prior art are briefly introduced below with reference to the accompanying drawings. The drawings are merely embodiments of the present invention, and persons with ordinary skill in the art in this field can derive other drawings based on these illustrated structures without creative effort.

[0015] EMBODIMENT 1 As shown in FIGS. 1 to 5, the present invention provides the following technical solutions: The ultra-short multi-stage folding umbrella has a center pole 1, a roller, and an umbrella rib frame 5. The central rod 1 is made up of six short tubes fitted together, and an upper wheel 2 and a lower wheel 3 are installed on the wheel. The upper wheel 2 is fixed to the top end of the center rod 1, and the lower wheel 3 slides on the short tube of the first section of the center rod 1, controlling the opening and closing of the ribs. The rib frame 5 is formed by combining a number of ribs 6, and each rib 6 is made up of an auxiliary rib 6a, a main rib 6b, a second rib 6c, a third rib 6d, a fourth rib 6e, and a coccyx 6f. One end of the main rib 6b is pivotally connected to the upper wheel 2, and one end of the auxiliary rib 6a is pivotally connected to the lower wheel 3. The front half of the auxiliary rib 6a is hingedly connected to the side of the middle part of the main rib 6b at a position offset from the side. The end of the rear half of the auxiliary bone 6a is hingedly connected to the side surface of the end of the second bone 6c at a position offset from the side surface. The other end of the main bone 6b is joined to one end of a second bone 6c, the other end of the second bone 6c is hinged at a laterally offset position to one end of a third bone 6d, the other end of the third bone 6d is hinged at a laterally offset position to one end of a fourth bone 6e, and the other end of the fourth bone 6e is hinged at a laterally offset position to one end of the coccyx 6f. In this embodiment, the number of sections of the short tube of the center rod 1 is increased to six, thereby achieving the purpose of shortening the length of the umbrella after it is stored, and the effect of reducing the volume of the umbrella after it is stored is achieved through the offset connection of the umbrella bones.

[0016] The end of the rear half of the auxiliary bone 6a is hingedly connected to the side surface of the end of the second bone 6c at a position offset from the side surface. The second rib 6c utilizes the space on the side and is folded out of position against the side of the auxiliary rib 6a, so that the thickness of the umbrella does not increase when stored. The other end of the second bone 6c is hingedly connected to a side surface of one end of the third bone 6d in a misaligned position, and the third bone 6d is folded misaligned against the side surface of the second bone 6c by utilizing the space on the side surface, without increasing the thickness of the umbrella when stored, and the other end of the third bone 6d is hingedly connected to a side surface of one end of the fourth bone 6e in a misaligned position. The fourth bone 6e also utilizes the space on the side and is folded out of position to the side opposite the third bone 6d, so as not to increase the thickness of the umbrella when it is stored, and the other end of the fourth bone 6e is hinged out of position to the side of one end of the tailbone 6f, and the tailbone 6f is folded out of position to the side opposite the fourth bone 6e, so as to utilize the space on the side and not to increase the thickness of the umbrella when it is stored. As a result, after the entire umbrella bones are folded, they become very thin and small in volume, taking up only a small space in thickness, making them lightweight and portable, and easily stored in a carry bag.

[0017] In this embodiment, adjacent ends of the auxiliary bone 6a and the third bone 6d, the second bone 6c and the fourth bone 6e, and the third bone 6d and the coccyx 6f are connected by rotation lines 7 that pull each other.

[0018] As shown in FIGS. 3 and 4, in this embodiment, the ribs 6 are arranged radially outward from the center pole 1, and the rib frame 5 is provided with five or six ribs 6.

[0019] In this embodiment, a ring-shaped push-pull member 4 is installed below the lower wheel 3. When opening the umbrella, the lower wheel 3 is pushed upward through the annular push-pull member 4, and the engaging hook on the first section short tube of the center rod 1 engages and is fixed, thereby maintaining the umbrella in the open position. When closing the umbrella, the annular push-pull member 4 is pulled downward to complete the storage of the umbrella.

[0020] The working principle and usage procedure of this invention are as follows: When using this device, the number of short tubes of the center rod 1 is increased to six to achieve the purpose of shortening the length of the umbrella after it is stored, and the effect of reducing the volume of the umbrella after it is stored is achieved by connecting the umbrella bones in an offset manner. The end of the rear half of the auxiliary rib 6a is hinged at a position offset from the end side of the second rib 6c, and the second rib 6c utilizes the space on the side and is folded offset from the side of the auxiliary rib 6a, preventing the thickness of the umbrella from increasing when it is stored. The other end of the second bone 6c is hingedly connected to a side surface of one end of the third bone 6d in a displaced manner, the third bone 6d is folded in a displaced manner onto the side surface of the second bone 6c, utilizing the space on the side, and the other end of the third bone 6d is hingedly connected to a side surface of one end of the fourth bone 6e in a displaced manner. The fourth bone 6e also utilizes the side space and is folded in a misaligned manner to the side opposite the third bone 6d, and the other end of the fourth bone 6e is hinged in a misaligned manner to the side of one end of the tailbone 6f, and the tailbone 6f utilizes the side space and is folded in a misaligned manner to the side opposite the fourth bone 6e, so that the thickness of the umbrella does not increase when it is stored. In this way, when the entire umbrella rib is folded, it becomes very thin and slim, with a small volume and minimal thickness, making it lightweight and easy to carry, and easy to store in an everyday bag.

[0021] Finally, I will explain. The above description is merely a preferred embodiment of the present invention, and is not intended to limit the present invention.
