Description

Technical Field

[0001] The present invention relates to accessories for folding umbrellas, and in particular to an umbrella rib with a small volume when stored. Background Art

[0002] In the prior art, there are umbrella ribs as shown in Figure 3 and Figure 4, which comprise a first main rib 10, a second main rib 20, a third main rib 30, a first secondary rib 110 and a second secondary rib 120. The first main rib 10 and the second main rib 20 are hingedly connected via a first joint 310, the second main rib 20 and the third main rib 30 are hingedly connected via a second joint 320, one end of the first secondary rib 110 and one end of the second secondary rib 120 are hingedly connected via a first hinge connection point 510, a position of the first secondary rib 110 close to the first hinge connection point 510 is hingedly connected to the first main rib 10 via a second hinge connection point 520, the other end of the second secondary rib 120 is hingedly connected to the first joint 310, both ends of a first tangent line 210 are hingedly connected to the second secondary rib 120 and the third main rib 30 respectively, the second joint 320 includes a third hinge connection point 3201 and a fourth hinge connection point 3202, the fourth hinge connection point 3202 is located at the protruding part of the second joint 320 and is hingedly connected to one end of a second pull line 220. In the prior art, the protruding part is arranged toward the third main rib 30, and what is described above is the structure of a three-folding umbrella rib. The four-folding umbrella further comprises a fourth main rib 40, which is hingedly connected via a third joint 330. In the case of a five-folding umbrella, it further comprises a fifth main rib 50, which is hingedly connected to the fourth main rib 40 via a fourth joint 340 and a fifth joint 350, both ends of a third pull line 230 are hingedly connected to the third main rib 30 and the fifth main rib 50 respectively, and the other end of the second pull line 220 is hingedly connected to the fourth main rib 40. As shown in Figure 3, this is a schematic diagram of the umbrella rib of a five-folding umbrella. Of course, the umbrella rib can be made into a three-folding umbrella rib or a four-folding umbrella rib as required.

[0003] In conventional designs, the protrusion of the second joint 320 is provided facing the third rib 30. In this way, when storing the umbrella, one end of the second pull wire 220, which is hinged to the protrusion, interferes with the third rib 30. This makes it difficult for the second rib 20 and the third rib 30 to get close together, and thus the volume of the umbrella ribs remains large when the umbrella is stored. [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] This invention provides umbrella ribs that take up less volume when stored. [Means for solving the problem]

[0005] This invention provides an umbrella frame that has a small volume when stored, comprising a first rib, a second rib, and a third rib, wherein the first and second ribs are hinged together via a first joint, and the second and third ribs are hinged together via a second joint, the second joint including a third hinge connection point and a fourth hinge connection point, the fourth hinge connection point being located on a projection of the second joint and hinged to one end of a second pull wire, the projection being provided in a direction away from the third rib.

[0006] As an improvement to the present invention, the present invention further comprises a first sub-rib and a second sub-rib, wherein one end of the first sub-rib and one end of the second sub-rib are hinged together via a first hinge connection point, and the position of the first sub-rib closest to the first hinge connection point is hinged together with the first main rib via a second hinge connection point, the other end of the second sub-rib is hinged together with the first joint, both ends of the first tangent are hinged together with the second sub-rib and the third main rib, respectively, and the other end of the second drawstring is hinged together with the fourth main rib.

[0007] As an improvement to the present invention, a fourth main rib is further provided, the fourth main rib being hinged to the third main rib via a third joint.

[0008] As an improvement to the present invention, a fifth main rib is further provided, the fifth main rib being hinged to the fourth main rib via the fourth joint and the fifth joint, and both ends of the third drawstring being hinged to the third main rib and the fifth main rib, respectively.

[0009] As an improvement to this invention, a tail section is further provided at the outer end of the fifth main rib.

[0010] This invention employs a structure in which the protrusion is provided facing away from the third rib. Therefore, when storing the umbrella, the end of the second drawstring that is hinged to the protrusion does not interfere with the third rib, and the end of the second drawstring that is hinged to the protrusion simply makes close contact with the third rib, resulting in a smaller volume of umbrella ribs when the umbrella is stored.
