Claims17
A telephone index device comprising:
- a flat slab-like base member of a substantially rectangular configuration for supporting a stack of index sheets on an upper surface thereof, a stack of index sheets each of said sheets having spaced apertures along at least one side thereof,
- an elongated closure strip member mounted adjacent one of the longer edges of said substantially rectangular base member for movement toward and away from said edge, said base member and strip member lying in the same plane,
- a plurality of inverted integral U-shaped loops mounted in spaced relation on one of said strip and base members with one leg thereof secured to said one of said members and with the other leg thereof having a free end overlying and contiguous to the upper surface of the other of said strip and base members, said loops being designed to engage the apertures in the index sheets,
- and means for releasably maintaining said strip member adjacent said one of said longer edges of said base member such that the free ends of the loops is closed off by one of said strip and base members to secure the index sheets on said loops, said means comprising at least one projection extending beyond the edge of one of said base and strip members,
- guide means on at least one of said strip and base members for guiding and maintaining said strip member in a plane parallel to the plane of said base member,
- engaging and holding means on the other of said base and strip members for frictionally engaging said at least one of said projections thereby locking the strip member in place against the base member in edge-to-edge relationship, said strip member being releasable therefrom by movement in a plane which is substantially parallel to the plane of the base;
- and means for mounting said device to a telephone instrument.
