<p><P>PROBLEM TO BE SOLVED: To provide a hinge which allows a plurality of hold-and-stay members to automatically perform lock operation in a fully open state, thereby improving durability, and allows easy unlocking. <P>SOLUTION: The hinge 71 includes one hinge plate 72, a plurality of the other hinge plates 73, 74 pivotally supported at a plurality of places in the longitudinal direction of the one hinge plate 72, and an opening angle restricting mechanism 75 for locking the opening operation of the hinge plates at a certain angle. The opening angle restricting mechanism 75 includes a plurality of pin-shaped guide members 85 each installed on the one hinge plate 72 side horizontal mounting plate portion 84a, a plurality of shorter pin-shaped locking members 86, and a plurality of hold-and-stay members 91, 92 integrally connected to a rod 88 rotatably and axially slidably fitted into the other hinge plates 73, 74. The hold-and-stay members 91, 92 are provided with fitting portions 93 fitted to the guide members 85, and engaging portions 94 engageable and disengageable to the locking members 86 by the axial movement of the rod 88 at the maximum open position. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
