<p>PURPOSE:To obtain a biaxial type hinge having the stability of operation and excellent durability by conducting the rotation of an intermediate connecting plate to a fixing side blade and the rotation of the rotary side blade to the intermediate connecting plate in specified order by the interposition of a lock lever. CONSTITUTION:The arcuate projecting edge surface section 10, linear edge surface section 11 and arcuate recessed edge surface section 12 of the bearing arm section 4a of a rotary side blade 4 and the arcuate projecting edge surface section 13 and linear edge surface section 14 of the bearing arm section 2a of the fixing side blade 2 are engaged and disengaged with and from the arcuate projecting edge surface section 15, first arcuate recessed edge surface section 16, linear edge surface section 17 and second arcuate recessed edge surface section 18 of a lock lever 9 in response to the place of the revolution of an intermediate connecting plate 7 and the rotary side blade 4 to the fixing side blade 2. Accordingly, the rotation of the intermediate connecting plate 7 is constrained to the rotary side blade 4 or the fixing side blade 2.</p> |
