Disclosure of the Invention
Problems to be Solved by the Invention
[0003] However, this kind of structural design lacks an effective locking mechanism and wind resistance design. Therefore, when external forces such as strong winds or bending in the reverse direction are applied, problems such as loosening of the joints, deformation of the umbrella ribs, and even breakage are likely to occur.
[0004] Also, in some improved designs, although a locking function is added, the structure is too complex or the close cooperation between parts is insufficient. As a result, the operation is cumbersome, the processing cost increases, and the wind resistance effect is limited. In multi-section or multi-fold umbrellas, due to the large number of joints, the force is easily dispersed. In the conventional structure, the overall rigidity is insufficient, and it cannot meet the high requirements of users for durability and wind resistance performance.
[0005] Therefore, the current market urgently needs a locking device that overcomes the shortcomings of the prior art, has a simple structure, high stability, and a wind resistance effect.
Means for Solving the Problems
[0006] This invention proposes a novel umbrella rib locking device that effectively solves the problems of loosening and insufficient wind resistance of conventional umbrella rib structures. This umbrella rib locking device includes components such as a locking member, interlocking member, positioning shaft, and reinforcing part, and its overall structure is compact and installed within the groove of the upper rib. [Effects of the Invention]
[0007] When the umbrella fabric opens, the lower ribs activate the closing mechanism through the interlocking mechanism, and the upper and lower stopper parts securely engage with the edges of the first and second joints, respectively, to close the umbrella. The wind-resistant part supports the groove of the tail rib, enhancing the wind-resistant capacity of the umbrella fabric. This design avoids problems such as joint loosening and umbrella frame deformation due to long-term use or external forces.
[0008] Furthermore, the locking device of this invention has a simple structure, is easy to install, possesses high modularity, can be flexibly adjusted and expanded according to the number of ribs of the umbrella, and can be applied to multi-section or multi-fold umbrella frames. This locking device not only increases the support stability of the umbrella fabric but also significantly improves the wind resistance performance of the umbrella frame, while simultaneously effectively reducing processing costs, thus possessing high practicality and industrial value.

[0010] An embodiment of the umbrella rib locking device of the present invention will be described with reference to Figures 1 to 6. The locking device 20 comprises a locking member 21, a connecting part 211, an upper stopper part 212, a lower stopper part 213, a reinforcing part 214, an interlocking member 22, a first connecting hole 221, a second connecting hole 222, a positioning shaft 23, etc., and is installed in the grooves of the related interlocking umbrella ribs such as the upper rib 11, lower rib 12, and tail rib 14 of the umbrella rib body 10.
[0011] The umbrella frame body 10 is pivotally mounted between the upper and lower sliders of the umbrella's central shaft. The umbrella frame body 10 includes an upper support rib 11 having a groove, an upper pivot hole 111, a first rivet hole 112, a second rivet hole 113, and a pivot hole 114 provided in the upper support rib 11, a lower support rib 12, a lower pivot hole 121, a first rivet hole 122, a first pivot hole 123, and a second pivot hole 124 provided in the lower support rib 12, a connecting rib 13, a first rivet hole 131 and a second rivet hole 132 provided in the connecting rib 13, a coccyx rib 14, a first pivot hole 141, a perforation 142, and a second pivot hole 143 provided in the coccyx rib 14, and a locking device 20, the locking device 20 being operably installed within the groove of the upper support rib 11.
[0012] The upper pivot hole 111 of the upper rib 11 and the lower pivot hole 121 of the lower rib 12 are pivotally connected to the upper and lower sliders of the umbrella central shaft, respectively. The first rivet hole 112 of the upper musculature 11, the first connecting hole 221 of the interlocking member 22 of the locking device 20, and the second pivot hole 124 of the lower musculature 12 are pivotally connected to each other and interlock. The second rivet hole 113 of the upper musculature 11 and the first pivot hole 123 of the lower musculature 12 are connected by rivet joints. The first rivet hole 122 of the inferior motulus 12 and the first rivet hole 131 of the connecting bone 13 are pivotally connected and work in conjunction. The second rivet hole 132 of the connecting bone 13 and the first pivot hole 141 of the coccyx 14 are pivotally connected and work together, thereby forming the first joint 30. The pivot hole 114 of the upper support bone 11, the second pivot hole 143 of the tail bone 14, and the positioning shaft 23 of the locking device 20 are pivotally connected and interlocked, thereby forming the second joint 40.
[0013] The locking device 20 is installed in the groove of the upper support bone 11. The first connection hole 221 of its linkage member 22 is pivotally connected and interlocked with the second pivot hole 124 of the lower support bone 12, and the second connection hole 222 of the linkage member 22 is pivotally connected and interlocked with the joint portion 211 of the locking member 21. The positioning shaft 23 is installed in the second pivot hole 143 of the tail bone 14 and is pivotally connected and interlocked with it to form the second joint 40.
[0014] During use, as the lower support bone 12 performs the operation of unfolding the umbrella surface upward, the lower support bone 12 moves the linkage member 22 of the locking device 20 in the directions of the first joint 30 and the second joint 40. As a result, the upper stopper portion 212 of the locking member 21 abuts against the upper edge of the first joint 30, and the lower stopper portion 213 abuts against the lower edge of the second joint 40 respectively, and the first joint 30 and the second joint 40 are in a locked state. At the same time, the reinforcing portion 214 supports and presses in the groove of the tail bone 14 behind the second joint 40. This locking device 20 assists in ensuring that the tail bone 14 of the umbrella surface is unfolded in the direction of the second joint 40, strengthens the support rigidity of the entire umbrella surface, and increases the wind resistance of the tail bone 14 portion by the reinforcing portion 214. Thereby, it prevents the first joint 30 and the second joint 40 from being deformed by external forces during use. The locking device 20 can be divided and added at necessary locations according to the number of joints of the umbrella ribs.
[0015] In another embodiment of the umbrella rib locking device of the present invention, the pivoting position and direction of the first connection hole 221 provided on the linkage member 22 of the locking device 20 can be changed according to the opening and closing mechanism of the umbrella ribs and different umbrella rib configurations.

The guide member 24 has a perforation, and the locking member 21 is inserted therethrough. The guide member 24 is provided at an appropriate position within the groove of the upper support rib 11, and serves to assist the smooth movement of the locking member 21 within the groove of the upper support rib 11.
[0017] In yet another embodiment of the umbrella rib locking device of the present invention, the positioning shaft 23 of the locking device 20 can have a guide groove 231. This guide groove 231 serves to assist the guidance when the locking member 21 accurately and smoothly fits into the first joint 30 and the second joint 40 to form a locked state.
[0018] In the umbrella rib locking device of the present invention, the outer shape, length or angle of the interlocking member 22, the upper stopper portion 212, the lower stopper portion 213 and the reinforcing portion 214 of the locking device 20 can be adjusted according to the form (multi - joint type, multi - fold type, etc.) of the umbrella rib body 10, enabling application to various types of umbrellas.
