Total Claims: 12
Claim 1
Independent Claim 170 words
A card directory comprising: first and second housing means hinged together; a plurality of card portions each having a first edge hingedly attached to said first housing means; a plurality of cards each hingedly attached to an edge opposite said first edge of a respective one of said card portions; said cards and card portions being normally individually folded together at the hinge between then and retained in a cavity between said first and second housing means; said cards and card portions being sized relative to said cavity; selectably movable retention means supported on said second housing for retaining selected card portions in said second housing, whereby when the cavity between said first and second housing is opened so that card portions are retained in said second housing above said first housing, selected cards and card portions are permitted to fall into said first housing in stacked individually folded relation and the card hinged to the uppermost card portion of said stack is permitted to unfold from said card portion.
Claim 2
Dependent Claim 170 words
A card directory comprising: first and second housing means hinged together; a plurality of card portions each having a first edge hingedly attached to said first housing means; a plurality of cards each hingedly attached to an edge opposite said first edge of a respective one of said card portions; said cards and card portions being normally individually folded together at the hinge between then and retained in a cavity between said first and second housing means; said cards and card portions being sized relative to said cavity; selectably movable retention means supported on said second housing for retaining selected card portions in said second housing, whereby when the cavity between said first and second housing is opened so that card portions are retained in said second housing above said first housing, selected cards and card portions are permitted to fall into said first housing in stacked individually folded relation and the card hinged to the uppermost card portion of said stack is permitted to unfold from said card portion.
Claim 3
Dependent Claim 170 words
A card directory comprising: first and second housing means hinged together; a plurality of card portions each having a first edge hingedly attached to said first housing means; a plurality of cards each hingedly attached to an edge opposite said first edge of a respective one of said card portions; said cards and card portions being normally individually folded together at the hinge between then and retained in a cavity between said first and second housing means; said cards and card portions being sized relative to said cavity; selectably movable retention means supported on said second housing for retaining selected card portions in said second housing, whereby when the cavity between said first and second housing is opened so that card portions are retained in said second housing above said first housing, selected cards and card portions are permitted to fall into said first housing in stacked individually folded relation and the card hinged to the uppermost card portion of said stack is permitted to unfold from said card portion.
Claim 4
Dependent Claim 170 words
A card directory comprising: first and second housing means hinged together; a plurality of card portions each having a first edge hingedly attached to said first housing means; a plurality of cards each hingedly attached to an edge opposite said first edge of a respective one of said card portions; said cards and card portions being normally individually folded together at the hinge between then and retained in a cavity between said first and second housing means; said cards and card portions being sized relative to said cavity; selectably movable retention means supported on said second housing for retaining selected card portions in said second housing, whereby when the cavity between said first and second housing is opened so that card portions are retained in said second housing above said first housing, selected cards and card portions are permitted to fall into said first housing in stacked individually folded relation and the card hinged to the uppermost card portion of said stack is permitted to unfold from said card portion.
Claim 5
Dependent Claim 10 words
Apparatus according to claim 1 wherein said cards are translucent.
Claim 6
Dependent Claim 66 words
Apparatus according to claim 1 wherein said first housing means is hingedly attached to a third housing supporting an array of switches, said cards each carrying indicia segmenting the cards into individual segments corresponding to individual ones of said switches, and registration means for positioning the card hinged to the uppermost card portion of said stack over said last-mentioned card are juxtapositioned to respective individual switches.
Claim 7
Dependent Claim 35 words
Apparatus according to claim 3 wherein light emitting indicators are associated with each switch of said array, and said cards are translucent so that operation of said indicators may be viewed through the selected card.
Claim 8
Dependent Claim 19 words
Apparatus according to claim 3 further including retention means for retaining the selected card to said third hoUsing means.
