Abstract:
1. A split barrel structure, which is adapted to couple a shaft of a pintle to form a hinge, the split barrel structure comprising: a first leaf portion, being a flat sheet member extended in a first leaf horizontal datum plane, and having a first edge and a second edge opposite to the first edge; and the first edge being divided into at least a barrel-forming section and an adjoining complement-forming section; at least one first partial barrel having a root end and a free end, the root end being connected to the at least one barrel-forming section of the first leaf portion, and the free end being extended from the root end in a first circular direction toward the barrel-forming section of the first leaf portion; at least one first complementary curved part having a root end and a free end, the root end being connected to the complement-forming section of the first leaf portion, and the free end being extended from the root end in the first circular direction, wherein first complementary curved part adjoins the first partial barrel part, and wherein the length of the first complementary curved part in the first circular direction is less than the length of the first partial barrel part in the first circular direction; a second leaf portion being a flat sheet member extended in a second leaf horizontal datum plane, and having a first edge and a second edge opposite to the first edge; and the first edge being divided into at least a barrel-forming section and an adjoining complement-forming section; the barrel-forming section on the second leaf portion being located corresponding to the complement-forming section on the first leaf portion, and the complement-forming section on the second leaf portion being located corresponding to the barrel-forming section on the first leaf portion; at least one second partial barrel having a root end and a free end, the root end being connected to the at least one barrel-forming section of the second leaf portion, and the free end being extended from the root end in a second circular direction opposite to the first circular direction toward the barrel-forming section of the second leaf portion; at least one second complementary curved part having a root end and a free end, the root end being connected to the complement-forming section of the second leaf portion, and the free end being extended from the root end in the second circular direction, wherein second complementary curved part adjoins the second partial barrel part, and wherein the length of the second complementary curved part in the second circular direction is less than the length of the second partial barrel part in the second circular direction; and at least one binding element, with which the first and the second leaf portions that have been aligned with one another face to face are bound together; whereby when the first and the second leaf portions have been bound together by the at least one binding element, the first partial barrel and the second partial barrel clamp the shaft of the pintle therebetween, the free end of the first complementary curved part ends at a point adjacent to the free end of the second partial barrel, and the free end of the second complementary curved part ends at a point adjacent to the free end of the first partial barrel.
