<p>Two pairs of guide-rods (1, 2) intersect at one end to be joined together in quadrilateral form 7-10), and are hinged to bases at the other end, for attachment of the hinge to the components (6, 11) which are to swivel together, as in 2803061. The gap between the hinge points (3, 4) for each guide-od pair on the base is smaller than the gap between the corresponding hinge points (7, 9) on the opposite connecting end. One guide-rod, at least, may be elastically resilient. This permits provision of a hinge swivel area of up to full 360 deg..</p> |
