Claim:
A barrier hinge assembly comprising an upper hinge assembly having an upper pintle device having a lower surface; and an upper pintle being formed on and protruding down from the lower surface of the upper pintle device and having an external thread; and an upper gudgeon device being mounted around the upper pintle of the upper pintle device, selectively abutting the lower surface of the upper pintle device and having an upper surface abutting the lower surface of the upper pintle device; a lower surface; and a through hole being formed through the upper gudgeon device and being mounted rotatably around the upper pintle; a lower hinge assembly having a lower gudgeon device having an upper surface; a lower surface; and a through hole being formed through the lower gudgeon device and having an inner wall; and a lower pintle device selectively engaging and holding the lower gudgeon device and having an upper surface facing and selectively abutting the lower surface of the lower gudgeon device; and a lower pintle being formed on and protruding up from the upper surface of the lower pintle device, being mounted rotatably through the through hole of the lower gudgeon device and being aligned with and facing the upper pintle of the upper pintle device; and a turnbuckle assembly being connected rotatably to the upper and the lower pintle devices, selectively squeezing the upper and the lower gudgeon devices between the upper and the lower pintle devices and releasing the upper and the lower pintle devices depending on which direction the turnbuckle assembly is turned and having a main tube having an upper open end; a lower open end abutting the upper surface of the lower gudgeon device and being mounted around the lower pintle of the lower pintle device; a sidewall; a sleeve being mounted in the upper open end of the main tube; and two elongated slots being formed longitudinally through the sidewall of the main tube near the upper open end diametrically opposite to each other; a connecting tube having an upper end abutting the lower surface of the upper gudgeon device; a lower end; a sidewall; a coaxial recess being formed in the lower end of the connecting tube and being mounted around the upper open end of the main tube; two pinholes being formed through the sidewall of the connecting tube diametrically opposite to each other and communicating with the coaxial recess; and a spring being mounted in the coaxial recess and abutting the connecting tube and the sleeve; a pin extending through the elongated slots of the main tube and the pinholes of the connecting tube; and an upper threaded hole being formed coaxially in the upper end of the connecting tube of the turnbuckle assembly and corresponding and being fastened to the externally threaded upper pintle of the upper pintle device.
