A spring hinge including a pair of hinge leaves having hollow knuckles on adjacent hinges which are arranged in substantially axial alignment such that the hollow knuckles comprise segments of a hinge barrel. A torsion spring made up of a resilient coiled spring member is housed within the hinge barrel. First and second pintles are disposed at opposing ends of the hinge barrel and extend into and between axially aligned knuckles of the hinge leaves. The first and second pintles each engaging the spring member in a locked arrangement such that the spring member extends in a substantially locked relation between the first and second pintles.

1. A spring hinge comprising:a pair of hinge leaves having hollow knuckles on adjacent edges arranged in substantially axial alignment such that the hollow knuckles comprise segments of a hinge barrel; a torsion spring comprising a resilient coiled spring member disposed within the hinge barrel; and a first pintle and a second pintle disposed at opposing ends of the hinge barrel, and extending into axially aligned knuckles of the hinge leaves, the first and second pintles each lockingly engaging the spring member at opposing ends of the spring member such that the spring member extends in substantially axially locked relation between the first and second pintles, whereby torsion forces are translated between the torsions spring and the pintles.
