  • Patent number: 4290217
    Abstract: A list finder, for example, a telephone index, is provided in which all of the main parts can be integrally moulded of plastic mostly by simple moulds which do not require undercut moulding; the only essential non-plastic parts being a hinge pin pivotally connecting a base and a cover, and a spring. The base has two spaced apart pedestals each of which has laterally spaced upwardly facing and downwardly facing hinge pin seats, with a clear space being provided below the downwardly facing hinge pin seat so that this can be moulded by a unitary mould member which also moulds the underside of the base. The cover includes a planar portion and two downwards projections having a central web and a cylindrically curved flange, the flanges being engageable in T-shaped slots in the sheets of the index. The web member has an upwardly facing hinge pin seat, and an aperture is provided above this seat and the flanges so that these can be moulded by a unitary mould member which also forms the top of the cover.
