Abstract
There is disclosed an improved load supporting hinge structure which includes bearing units disposed between adjacent knuckles of the leaves of the hinge to afford both the desired support and smooth operation thereof. Each of the knuckles of the hinge structure includes a central axial bore, the bores being aligned coaxially. Each of the ball-bearing units includes an axially outer and an axially inner race member and a train of bearing members mounted for movement therebetween. The respective race members are constructed so that the bearing unit can accommodate both vertical and horizontal loads, with uniform loading of the load supporting bearing elements being attained by provision for slight relative movement between the race members and the bearing elements.
