Claims

[Scope of Claim for Utility Model Registration] Among pivot hinges used in architecture, a pivot hinge consisting of two upper and lower plate-like blades has a shaft core 9 that can be freely screwed onto and removed from the lower blade 7 from both upper and lower surfaces of the lower blade 7. The total length L of the shaft core 9 is not less than the sum of twice the thickness t of the blade and the thickness S of the washer 8,
The counterbore 11 of the mounting screw hole 10 is provided from both sides of the blades 6 and 7. The shaft core 9 has a thin warp hole 1 passing through the center of the shaft core 9.
A retrofitted pivot hinge characterized by the following: 8.
