An invented hinge for coupling three buoyant-slats pool cover sections together is described wherein three, modified, longitudinal buoyant slats are coupled for pivoting around three angularly spaced, parallel hinge axes aligned with the slats by a plurality of hinge plates each defining a coupling aperture received and pinned within registering hinge bays penetrating into adjacently positioned, longitudinal side flotation chambers of the three modified buoyant slats by a longitudinal hinge pin passing through the coupling apertures of the hinge plates received in the hinge bays inside of the flotation chamber of each of the three modified, buoyant slats. |
