Description

Technical Field

[0001] This utility model relates to accessories for folding umbrellas, and in particular to an umbrella rib structure that can enhance wind resistance. Background Technology

[0002] Chinese patent document CN222692868U discloses an umbrella frame, including a first main bone, a second main bone, a third main bone, a first branch bone, and a second branch bone. The first main bone and the second main bone are hinged together by a first connector, and the second main bone and the third main bone are hinged together by a second connector. One end of the first branch bone is hinged to one end of the second branch bone by a first eyelet, and the first branch bone is hinged to the first main bone by a second eyelet near the first eyelet. The other end of the second branch bone is hinged to the first connector, and the two ends of a first wire are respectively hinged to the second branch bone and the third main bone. The second connector includes a third eyelet and a fourth eyelet, and the fourth eyelet is located on the protrusion of the second connector and is hinged to one end of a second pull wire. To ensure the curvature of the canopy when open, the first, second, and third main ribs, as well as the first and second branch ribs, are mostly made with a certain degree of flexibility during manufacturing. However, umbrellas made with such flexible main and branch ribs have very weak wind resistance and are easily blown over by the wind. To solve this problem, the first, second, and third main ribs, as well as the first and second branch ribs, are made of plastic parts with a certain degree of rigidity. However, in use, umbrellas made with such rigid main and branch ribs generally do not easily flip over, but when the wind force reaches a certain level, the main ribs and / or branch ribs are easily broken. Utility Model Content

The inner side of the end of the long groove 1 is hinged to the inner end of the central rib 3 via a first central rib joint 31. One end of the short groove 2 is hinged to the middle of the long groove 1 via a first eyelet 11. A second eyelet 21 is provided at one end of the short groove 2 near the middle of the long groove 1. The second eyelet 21 is connected to one end of the umbrella closing spring and is also hinged to one end of the short pull wire 6. The first central rib joint 31 includes a third eyelet 311 and a fourth eyelet 312. The third eyelet 311 is hinged to the inner side of the end of the long groove 1, and the fourth eyelet 312 is hinged to the other end of the short pull wire 6. The other end of the umbrella closing spring is connected to the... A fifth eyelet 12 connects the first eyelet 11 and the third eyelet 311. A groove 313 is provided at the head end of the first central rib connector 31 (in this embodiment, the groove 313 is a V-shaped groove on the end face of the first central rib connector 31; of course, the groove 313 can also be a U-shaped groove, etc.). The connection hole between the third eyelet 311 and the first central rib connector 31 is an elongated hole 314 (the elongated hole 314 can be an elliptical hole or a racetrack-shaped hole). A sixth eyelet 13 is provided between the third eyelet 311 and the fifth eyelet 12 on the elongated groove 1. The sixth eyelet 13 is configured such that when the umbrella rib is fully opened, under the tension of the short pull wire 6, the groove 313 just locks onto the sixth eyelet 13. In this utility model, "eyelet" is an industry term; an eyelet is actually a type of rivet.
