Abstract:
A hinge, comprising:a) a first leaf which is coextensive with the hinge and has a flat web which is coextensive with the teal for attachment to a movable member, the web terminating at a partially enclosed loop portion which is continuous throughout its length, coextensive with the web; and has a coextensive opening therein; b) a second leaf which is coextensive with the first leaf and has a flat web which is coextensive with the second leaf for attachment to a fixed member, the web of the second leaf terminating at a head portion which is rotatably and slidably received in the loop portion through the opening therein, the head portion being coextensive with the loop portion and divided longitudinally into a number of elongated hollow cylindrical wall portions with comparatively short spaces between them, the cylindrical wall portions having axially aligned bores for receiving a pivot pin; c) a continuous pivot pin extending through the bores and spaces between the cylindrical wall portions, the pivot pin being coextensive with the leafs; d) a plastic bearing disposed in, and longitudinal filling, each of the spaces between the cylindrical wall portions, each bearing having a bore through which the pivot pin passes, the bores of the bearings being axially aligned with the bores of the cylindrical wall portions of the head portion, each bearing shaped to fit snugly in the loop portion of the first leaf; the bearings designed to hold the loop portion in spaced relation from the head portion, at least when the hinge is closed where the leafs are side-by-side in closest spaced relation, to facilitate relative rotation of the leafs, and; e) means coacting with the first leaf, at least two plastic bearings, and the pivot pin for securing the two leafs, bearings and pivot pin together to prevent relative axial movement between the leafs.
