Description

Technical Field

[0001] The utility model relates to accessories for folding umbrellas, in particular to an umbrella frame with a smaller volume when the umbrella is folded. Background Art

[0002] In the prior art, there is an umbrella frame such as Figure 3 and Figure 4 As shown, it includes a first main bone 10, a second main bone 20, a third main bone 30, a first branch bone 110 and a second branch bone 120. The first main bone 10 and the second main bone 20 are hinged through a first joint 310, and the second main bone 20 and the third main bone 30 are hinged through a second joint 320. One end of the first branch bone 110 and one end of the second branch bone 120 are hinged through a first hinge point 510, and the position of the first branch bone 110 near the first hinge point 510 is hinged to the first branch bone 120 through the second hinge point 520. The main bone 10 is hinged; the other end of the second branch bone 120 is hinged to the first joint 310, and the two ends of the first connection 210 are respectively hinged to the second branch bone 120 and the third main bone 30; the second joint 320 includes a third hinge point 3201 and a fourth hinge point 3202, and the fourth hinge point 3202 is located on the protrusion of the second joint 320 and is hinged to one end of the second pull line 220. In the prior art, the protrusion is arranged toward the third main bone 30, and the above description is the structure of the three-fold umbrella bone. If it is a four-fold umbrella, it also includes a fourth main bone 40, and the fourth main bone 40 is hinged through the third joint 330. If it is a five-fold umbrella, it also includes a fifth main bone 50, and the fifth main bone 50 is hinged to the fourth main bone 40 through the fourth joint 340 and the fifth joint 350. The two ends of the third pull line 230 are respectively hinged to the third main bone 30 and the fifth main bone 50, and the other end of the second pull line 220 is hinged to the fourth main bone 40. Figure 3 The diagram shown is a schematic diagram of an umbrella frame of a five-fold umbrella. Of course, the umbrella frame can also be made into a three-fold umbrella frame or a four-fold umbrella frame according to needs.

[0003] In the prior art, since the protrusion of the second joint 320 is arranged toward the third main frame 30, when the umbrella is folded, the end of the second pull wire 220 hinged to the protrusion will interfere with the third main frame 30, making it difficult for the second main frame 20 and the third main frame 30 to get close to each other. As a result, the volume of the umbrella frame is still relatively large when the umbrella is folded. Utility Model Content

[0004] The utility model provides an umbrella frame with a smaller volume when the umbrella is folded.

[0005] The utility model provides an umbrella frame with a smaller volume when folded, comprising a first main bone, a second main bone and a third main bone, wherein the first main bone and the second main bone are hinged via a first joint, and the second main bone and the third main bone are hinged via a second joint; the second joint comprises a third hinge point and a fourth hinge point, the fourth hinge point is located on a protruding portion of the second joint and is hinged to one end of a second pull line; the protruding portion is arranged in a direction away from the third main bone.

[0006] As an improvement to the present invention, it further includes a first branch bone and a second branch bone, wherein one end of the first branch bone is hinged to one end of the second branch bone through a first hinge point, and the first branch bone is hinged to the first main bone through a second hinge point near the first hinge point; the other end of the second branch bone is hinged to the first joint, and the two ends of the first connection are respectively hinged to the second branch bone and the third main bone; the other end of the second pull wire is hinged to the fourth main bone.

[0007] As an improvement to the utility model, it further comprises a fourth main bone, wherein the fourth main bone is hinged to the third main bone via a third joint.

[0008] As an improvement to the utility model, it further comprises a fifth main bone, wherein the fifth main bone is hinged to the fourth main bone through a fourth joint and a fifth joint, and the two ends of the third pull line are hinged to the third main bone and the fifth main bone respectively.

[0009] As an improvement to the present invention, an umbrella tail is further provided at the outer end of the fifth main bone.

[0010] Since the utility model adopts a structure in which the protrusion is arranged in a direction away from the third main frame, when the umbrella is folded, the end of the second pull line hinged to the protrusion will not interfere with the third main frame, but the end of the second pull line hinged to the protrusion is close to the third main frame, so that the volume of the umbrella frame is smaller when the umbrella is folded. BRIEF DESCRIPTION OF THE DRAWINGS
