<p>PURPOSE:To contrive opening or closing certainly with one touch by setting a sub virtual circular line to be drawn by a door sub-shaft with the center of the fixing sub-shaft of a sub-hinge, so that it may cross on the way over a main virtual circular line to be drawn by a door main-shaft with the center of the fixing main-shaft of a main hinge. CONSTITUTION:The rear corner section of a box-type frame 1 is provided with a fixing main-shaft 11, and the interior of a recessed section 12 formed on the side section of a door 7 is provided with a door main-shaft 13, respectively. Besides, via a main hinge 15 with a U-shaped link 14 connected rotatably to over the shafts 11, 13, the door 7 is fitted on the frame 1. Besides, over the upper side section and the lower side section of the hinge 15, a sub hinge 19 with a link 18 connected to over a fixing sub shaft 16 and a door sub shaft 17 is placed. Then, in the first half of releasing, the door 7 is opened along a main virtual circular line 20, and from a close side to be crossed over a sub virtual circular line 21, the internal surface side of the door 7 is reversed to the external side and is released in parallel with a frame side-wall. Accordingly, it can be certainly released with one touch action.</p> |
