  • Patent number: 5186496
    Abstract: An improved photographic album for displaying aligned planar pages includes an elongated rigid spine defining a mounting surface on which a pair of spaced retainers are mounted. Each planar page has a flexible margin which carries an elongated flat hinge having hooks at either end projecting outwardly from the flexible margin toward the retainers. Each hook engages a retainer to hold the page firmly in place yet allow the page to pivot relative to the spine to flip the pages in the album. A pair of aligned notches are present in the front lip of each retainer to facilitate insertion of the hooks into the slots. One of the notches is a rounded bearing surface against which a hook can bear to flex the hook and allow the other hook to move toward engaging the other retainer. That other retainer has a ramped notch along which the second hook can ride and against which the second hook can flex to move into engagement with the retainer.
