Abstract
Abstract A folded, wallet-type display of relative currency values. The display involves the use of removably attachable currency strips whose position relative a window in the display can be changed to thereby reflect fluctuations in exchange rates. In a preferred form, logarithmic currency scales adjacent the display window and logarithmic currency scales on the movable currency strips permits currency conversion by direct visual comparisons between corresponding units of two different currencies.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
357 words
A folded, wallet-type display of relative currency values which is operable to convert values of at least two different currencies as exchange rates vary, said display comprising: a. only first and second opaquE leaves, each leaf having a lateral edge and a bottom edge, said leaves being pivotally connected to each other along only one lateral edge thereof to form a two-leaf booklet; b. at least one opaque elongated currency strip having a bottom edge and a lateral edge, said bottom and lateral edges being essentially perpendicular to one another and said currency strip bottom edge being substantially narrower than the bottom edge of said opaque leaves, said currency strip being marked with indicia of a plurality of units of a second currency, said indicia arranged only in a single row progressing along the length of said strip parallel to said strip lateral edge; c. said first leaf containing at least one display opening which is fixedly positioned in said first leaf and which has a width generally limited to the width of the currency indicia row on said currency strip, said display opening allowing a portion of a currency strip positioned therebeneath to be exposed to the outer face of said first leaf, each of said display openings being positioned only laterally from one another along a direction generally parallel to said leaf bottom edge; d. said first leaf being marked with fixed indicia of at least one unit of a first currency, said indicia located on the outer face of said first leaf generally adjacent to a lateral edge of said display opening; and e. means for attaching said currency strip to said leaf containing said display opening so as to allow said currency strip to be operably movable only in a direction parallel to the lateral edge of said leaf and to allow at least a portion of said strip to be exposed in said display opening when said first leaf is positioned over said second leaf to allow selective matching of two currency indicia through said opening, said matching currency indicia corresponding to the prevailing exchange rate between the first and second currencies.
Claim 2
Dependent Claim
357 words
A folded, wallet-type display of relative currency values which is operable to convert values of at least two different currencies as exchange rates vary, said display comprising: a. only first and second opaquE leaves, each leaf having a lateral edge and a bottom edge, said leaves being pivotally connected to each other along only one lateral edge thereof to form a two-leaf booklet; b. at least one opaque elongated currency strip having a bottom edge and a lateral edge, said bottom and lateral edges being essentially perpendicular to one another and said currency strip bottom edge being substantially narrower than the bottom edge of said opaque leaves, said currency strip being marked with indicia of a plurality of units of a second currency, said indicia arranged only in a single row progressing along the length of said strip parallel to said strip lateral edge; c. said first leaf containing at least one display opening which is fixedly positioned in said first leaf and which has a width generally limited to the width of the currency indicia row on said currency strip, said display opening allowing a portion of a currency strip positioned therebeneath to be exposed to the outer face of said first leaf, each of said display openings being positioned only laterally from one another along a direction generally parallel to said leaf bottom edge; d. said first leaf being marked with fixed indicia of at least one unit of a first currency, said indicia located on the outer face of said first leaf generally adjacent to a lateral edge of said display opening; and e. means for attaching said currency strip to said leaf containing said display opening so as to allow said currency strip to be operably movable only in a direction parallel to the lateral edge of said leaf and to allow at least a portion of said strip to be exposed in said display opening when said first leaf is positioned over said second leaf to allow selective matching of two currency indicia through said opening, said matching currency indicia corresponding to the prevailing exchange rate between the first and second currencies.
Claim 3
Dependent Claim
26 words
The display of claim 1 wherein said fixed indicia on said outer face of said first leaf represent only a single unit of said first currency.
Claim 4
Dependent Claim
35 words
The display of claim 2 wherein printed information of national significance is positioned on the side of each of said currency strip opposite the side on which the currency indicia of the corresponding country appear.
Claim 5
Dependent Claim
53 words
The display of claim 2 wherein there are at least two currency strips, each containing currency indicia for a separate country, and wherein there are at least two display openings positioned in said first leaf in a generally side-by-side arrangement, thereby allowing the currencies of more than two countries to be simultaneously compared.
Claim 6
Dependent Claim
511 words
A folded, wallet-type display of relative currency values which is operable to convert numerous currency values of at least two different currencies as exchange rates vary, said display comprising: a. only first and second opaque leaves, each leaf having a lateral edge and a bottom edge, said leaves being pivotally connected to each other along only one lateral edge thereof to form a two-leaf booklet; b. at least one opaque elongated currency strip having a bottom edge and a lateral edge, said bottom and lateral edges being essentially perpendicular to one another and said currency strip bottom edge being substantially narrower than the bottom edge of said opaque leaves, said currency strip being marked with indicia of a plurality of units of a second currency, said indicia arranged only in a single row progressing along the length of said strip generally parallel to said strip lateral edge; c. said first leaf containing at least one display opening which is elongated generally parallel to the lateral edge of said leaf and which is fixedly positioned in said first leaf and which has a width limited to the width of the currency indicia row on said currency strip, said display opening allowing a portion of a currency strip positioned therebeneath to be exposed to the outer face of said first leaf, each of said display openings being positioned only lateralLy from one another along a direction generally parallel to said leaf bottom edge; d. said first leaf being marked with fixed indicia of at least one unit of a first currency, said indicia located on the outer face of said first leaf generally adjacent a side edge of said display opening and along a line generally parallel to the side edge of said elongated display opening, said indicia representing a plurality of units of said first currency arranged according to a selected logarithmic scale and extending generally along the length of said window opening; e. said fixed indicia on said currency strip being arranged in a logarithmic scale, said logarithmic scale corresponding to the logarithmic scale of said outer leaf so that units of the one currency can be converted to units of the second currency by direct visual comparison of adjacent currency indicia when said currency strip is moved to a suitable position with respect to said indicia on the outer leaf face; f. means for attaching said currency strip to said leaf containing said display opening so as to allow said currency strip to be movable in a direction parallel to the lateral edge of said leaf and to allow at least a portion of said strip to be exposed in said display opening when said first leaf is positioned over said second leaf thereby allowing the indicia on the exposed portion of said currency strip to be alined with the fixed indicia on the outer face of said first leaf such that selective matching of two currency indicia through said opening may be accomplished, said matching currency indicia corresponding to the prevailing exchange rate between the first and second currencies;
