<p>PURPOSE:To obtain a biaxial type hinge having the stability of operation and excellent durability by conducting the revolution of an intermediate connecting plate to a fixing side blade and the revolution of a rotary side blade to the intermediate connecting plate in specified order by the constraint function of a lock lever. CONSTITUTION:The can edge surface section 16 of a lock lever 9 is engaged and disengaged with and from the first linear edge surface section 11, arcuate projecting edge surface secition 10 or second linear edge surface section 12 of the bearing arm section 4a of the rotary side blade 4 in response to the places of the rotation of an intermediate connecting plate 7 to a fixing side blade 2 and the rotary side blade 4. The intermediate connecting plate 7 is constrained to the rotary side blade 4 or the fixing side blade 2 by engaging and disengaging the lock-stop projecting section 15 of the lock lever 9 with and from the arcuate projecting edge surface section 13 or recessed section 14 of the bearing arm section 2a of the fixing side blade 2.</p> |
