Description

[Technical Field]

[0001] The present invention belongs to the field of umbrella equipment, and specifically relates to a lightweight, ultra-short umbrella rib. [Background technology]

[0002] Umbrellas are an essential tool in daily life. They provide sun protection on sunny days and protection from the wind and rain on rainy days. In recent years, the number of people carrying umbrellas has increased, and the demand for portability of umbrellas has also risen. Traditional long-handled umbrellas and standard folding umbrellas have found it difficult to meet users' portability needs. Especially for commuting and traveling, umbrellas that are lightweight and not portable can be a burden when traveling.

[0003] The ultra-short umbrellas on the market are still insufficient for some users who want to put them directly into small bags or trouser pockets, and the storage length is still insufficient, so this invention provides a portable and lightweight ultra-short umbrella rib. Summary of the Invention [Problem to be solved by the invention]

[0004] To solve the problems raised in the background art above, this invention provides a lightweight, ultra-short umbrella rib, and by increasing the number of short tube sections in the center rod to six, it achieves the purpose of shortening the length of the umbrella after storage. The offset hinges and groove design of the umbrella ribs achieve the effect of volumetric shrinkage after storage. [Means for solving the problem]

[0005] To achieve the above objectives, this invention provides a technical solution for a lightweight ultra-short umbrella rib, which includes a center rod, a spring, and a rib frame. The center rod is made up of six sections of short tubes connected to each other. The spring consists of an upper spring and a lower spring. The upper spring is fixed to the end of the center rod, and the lower spring slides on the first section of the short tube of the center rod to control the opening and closing of the rib frame. The rib frame combines multiple ribs, each of which consists of a bridge rib, a first rib, a second rib, a third rib, a fourth rib, and a support rib. One end of the support rib is pivotally attached to the upper spring, and the other end is hinged to one end of the second rib. One end of the bridge rib is pivotally attached to the lower spring and is hinged to the center of the bridge rib and the support rib, and the other end of the bridge rib is hinged to one end of the first rib.

[0006] Preferably, the other end of the first bone is hinged to one end of the second bone, the other end of the second bone is hinged offset to a side of one end of the third bone, the other end of the third bone is hinged to one end of the fourth bone, and the other end of the fourth bone is hinged to one end of the coccyx.

[0007] Furthermore, a pulling wire is connected between the adjacent ends of the first bone and the third bone, the second bone and the fourth bone, and the third bone and the coccyx to pull the bones together.

[0008] Furthermore, a tip is attached to the other end of the tailbone, and when the umbrella is folded and stored, the tip is stored in the umbrella handle.

[0009] Furthermore, the auxiliary ribs, support ribs, first ribs and third ribs are made of aluminum alloy material and are designed in a groove shape.

[0010] Furthermore, the second rib, the fourth rib and the coccyx are made of glass fiber or carbon fiber material.

[0015] Hereinafter, the embodiments of the present invention will be described in detail. An example of this embodiment is shown in the drawings, and the same or similar reference numerals throughout the drawings indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are illustrative and are used only to explain the present invention, and cannot be understood as limiting the present invention.

[0016] 1 to 7, the present invention provides a technical solution for a lightweight ultra-short umbrella rib, which includes a center rod 1, a roller, and a rib frame 5. The center rod 1 has six short tubes connected to each other, and the roller consists of an upper roller 2 and a lower roller 3. The upper roller 2 is fixed to the tip of the center rod 1, and the lower roller 3 slides on the first short tube of the center rod 1 to control the opening and closing of the rib frame 5. The rib frame 5 is made up of a plurality of ribs 6. Each rib 6 is composed of a support rib 6a, a first rib 6b, a second rib 6c, a third rib 6d, a fourth rib 6e, a tail rib 6f and an auxiliary rib 6g, one end of the auxiliary rib 6g is pivotally attached to the upper turntable 2 and the other end is hinged to one end of the second rib 6c, one end of the support rib 6a is pivotally attached to the lower turntable 3 and hinged to the center of the support rib 6a and the auxiliary rib 6g, and the other end of the support rib 6a is hinged to one end of the first rib 6b.

[0017] Specifically, the other end of the first bone 6b is hinged to one end of the second bone 6c, the other end of the second bone 6c is hinged to a side surface of one end of the third bone 6d with a shifted position, the other end of the third bone 6d is hinged to one end of the fourth bone 6e, and the other end of the fourth bone 6e is hinged to one end of the coccyx 6f.

[0018] Specifically, a pulling wire 7 is connected between the adjacent ends of the first bone 6b and the third bone 6d, the second bone 6c and the fourth bone 6e, and the third bone 6d and the coccyx 6f, for pulling each other.

[0019] Specifically, a tip 8 is attached to the other end of the tailbone 6f, and when the umbrella is folded and stored, the tip 8 is stored in the handle 9 of the umbrella.

[0020] To reduce the weight and thickness of the ribs when folded, the auxiliary ribs 6g, support ribs 6a, first rib 6b, and third rib 6d are made of aluminum alloy and are designed with a groove. The pull wire 7 connecting the second rib 6c and the fourth rib 6e is housed in the groove of the third rib 6d. The groove serves to store the ribs when the umbrella is folded, thereby reducing the folded thickness.

[0021] In order to reduce the weight of the entire umbrella, the second rib 6c, the fourth rib 6e and the tail rib 6f are made of glass fiber or carbon fiber material.

[0022] As shown in Figures 8 and 9, in this embodiment, the rib frame 5 is arranged around the center rod and distributed outward. The rib frame 5 can have five or six ribs 6. The rib frame 5 can be used for round-rib or flat-rib umbrellas.

[0023] A ring-shaped push / pull device 4 is provided below the lower roller 3, and when opening the umbrella, the ring-shaped push / pull device 4 pushes up the lower roller 3 until it engages with the snap of the first stage short tube of the center rod 1, maintaining the open state, and when storing the umbrella, the ring-shaped push / pull device 4 is pulled downward to complete storage.

[0024] Operating principle and usage process of this invention: When using this invention, by holding the umbrella handle 9 and pushing up the ring-shaped push-pull device 4, the lower roller 3 moves upward, extending the six-section center rod 1 and opening the rib frame 5. The rib frame 5 can have five or six ribs 6. When the lower roller 3 moves upward, one end of the rib 6a fixed to the lower roller 3 moves upward accordingly, while the other end moves outward, separating from the center rod 1. The rib 6a is hinged to the middle of the auxiliary rib 6g. When one end of the rib 6a moves outward, one end of the auxiliary rib 6g also moves outward. At the same time, the first rib 6b, second rib 6c, third rib 6d, fourth rib 6e, and tail rib 6f extend outward together under the pull of the pull wire 7, completing the opening of the umbrella.

[0025] To store the umbrella, the ring-shaped push-pull device 4 is pulled to move the lower roller 3 downward, causing the six-stage center rod 1 to retract and fold the rib frame 5. As the lower roller 3 moves downward, each stage of the ribs 6 folds inward alternately clockwise and counterclockwise. "Folding inward" refers to folding toward the center rod 1. As shown by the arrow in Figure 2(A), taking the perspective of the ribs 6 on the right side of the center rod 1 as an example, as the lower roller 3 moves downward, one end of the rib 6a fixed to the lower roller 3 moves downward in a parallel motion, and the end connecting the rib 6a to the first rib 6b is folded inward counterclockwise. The ends of the second rib 6c connecting the auxiliary rib 6g and the first rib 6b are both folded inward clockwise. The end of the third rib 6d connecting the second rib 6c is folded inward counterclockwise. One end of the fourth rib 6e, which connects to the third rib 6d, is folded inward in a clockwise direction. One end of the coccyx 6f, which connects to the fourth rib 6e, is folded inward in a counterclockwise direction. The end of the coccyx 6f, where the tip 8 is located, is folded inward in a clockwise direction. Conversely, when the rib 6 is on the left side of the shaft 1, the direction of inward folding is reversed from the right side. Whether the rib 6 is on the left or right side of the shaft 1, after the rib 6 is folded and stored, the coccyx 6f and tip 8 face toward the ground, i.e., toward the umbrella handle 9, and the tip 8 is stored within the umbrella handle 9.

[0026] As shown in Figures 2(B), 3, and 4, after folding the ribs, the support rib 6a is folded to the side of the center rod 1. The first rib 6b is folded to the side of the support rib 6a. The second rib 6c is folded to the side of the first rib 6b. The third rib 6d is folded and offset to the side of the second rib 6c. The fourth rib 6e is folded to the side of the third rib 6d. The tail rib 6f is folded to the side of the fourth rib 6e. The offset folding structure of the second rib 6c and the third rib 6d allows the two ribs to occupy only the radial space of the first rib, reducing the thickness of the umbrella when stored.

[0027] As shown in Figure 7, the six-section center rod gradually retracts inward when folded. When the six-section center rod is combined with the six-section ribs, the overall volume of the umbrella becomes smaller, allowing it to fit easily into a bag or pocket.

[0028] The auxiliary ribs 6g, support ribs 6a, first rib 6b, and third rib 6d are made of aluminum alloy and are designed with a grooved shape. The pull wire 7 connecting the second rib 6c and the fourth rib 6e is housed in the groove of the third rib 6d. The groove design serves to store the ribs when the umbrella is folded, thereby reducing the folded thickness. The second rib 6c, fourth rib 6e, and tail rib 6f are made of glass fiber or carbon fiber. The combination of aluminum alloy and lightweight fiber material reduces the overall weight of the umbrella, making it easier to carry.

[0029] The above is merely a specific embodiment of the present invention, and the scope of protection of the present invention is not limited thereto, and any changes or substitutions that can be conceived without creative labor are also included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be equivalent to the scope of protection limited by the claims. [Explanation of symbols]
