ABSTRACT:
A lightweight piano-type hinge is comprised of a pair of conventional leafs with knuckles which are in mating meshing relation. The hinge employs a unique hinge pine which comprises a pair of different length hinge pins with an attached coil spring between them for resisting relative rotation of the leafs to spring load the hinge. A pair of large headed machine screw are at each end of the leafs to threadably engage the hinge pins which are selectively secured to the two leafs.
