Abstract
Abstract A pad of regular hexagonal flexible sheets each having a front surface adapted to be written on, and a coating of repositionable pressure sensitive adhesive over a portion of its rear surface releasably adhering the sheet to an underlying sheet in the pad. Information can be written on the front surfaces of the sheets, and the individual written on sheets can be adhered to a planar surface in side by side relationship with edge portions of up to six adjacent sheets in contact to represent relationships between the information on the sheets.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
191 words
A pad comprising a plurality of flexible sheets each having a regular hexagonal peripheral edge defined by six straight edge portions, a front surface adapted to be written on, a rear surface, and a coating of repositionable pressure sensitive adhesive over a portion of said rear surface extending across the rear surface of said sheet between opposite straight edge portions releasably adhering said sheet to an underlying sheet in said pad with the straight edge portions of the peripheral edges of said sheets in alignment, said rear surface of each sheet having a portion free of adhesive adjacent the intersection of two straight edge portions on one side of said opposite straight edge portions to afford removal of said sheets from said pad by peeling the uppermost sheet from underlying sheets in the pad, whereby a user may write information on the front surfaces of a plurality of the sheets, remove said plurality of the sheets, and adhere the removed sheets to a planar surface in side by side relationship with straight edge portions of up to six adjacent sheets in contact to represent relationships between the information on the sheets.
Claim 2
Dependent Claim
191 words
A pad comprising a plurality of flexible sheets each having a regular hexagonal peripheral edge defined by six straight edge portions, a front surface adapted to be written on, a rear surface, and a coating of repositionable pressure sensitive adhesive over a portion of said rear surface extending across the rear surface of said sheet between opposite straight edge portions releasably adhering said sheet to an underlying sheet in said pad with the straight edge portions of the peripheral edges of said sheets in alignment, said rear surface of each sheet having a portion free of adhesive adjacent the intersection of two straight edge portions on one side of said opposite straight edge portions to afford removal of said sheets from said pad by peeling the uppermost sheet from underlying sheets in the pad, whereby a user may write information on the front surfaces of a plurality of the sheets, remove said plurality of the sheets, and adhere the removed sheets to a planar surface in side by side relationship with straight edge portions of up to six adjacent sheets in contact to represent relationships between the information on the sheets.
Claim 3
Dependent Claim
51 words
A pad according to claim 1 wherein said front surface of said pad has a generally triangular portion adjacent the intersection of two straight edge portions that is visually distinctive with respect to the other portion of the front surface to form a pointer on said front surface at said intersection.
Claim 4
Dependent Claim
24 words
A pad according to claim 1 wherein said sheets have a dimension between opposite straight edge portions of at least 10 centimeters (4 inches).
Claim 5
Dependent Claim
192 words
A pad comprising a plurality of flexible sheets each having a regular hexagonal peripheral edge defined by six straight edge portions, a front surface adapted to be written on, a rear surface, and a coating of repositionable pressure sensitive adhesive over a portion of said rear surface over the center of the sheet and between opposite straight edge portions releasably adhering said sheet to an underlying sheet in said pad with the straight edge portions of the peripheral edges of said sheets in alignment, and said rear surface of each sheet having two portions free of adhesive adjacent the intersections of the two straight edge portions on both sides of said opposite straight edge portions to afford removal of said sheets from said pad by peeling the uppermost sheet from underlying sheets in the pad, whereby a user may write information on the front surfaces of a plurality of the sheets, remove said plurality of the sheets, and adhere the removed sheets to a planar surface in side by side relationship with straight edge portions of up to six adjacent sheets in contact to represent relationships between the information on the sheets.
Claim 6
Dependent Claim
192 words
A pad comprising a plurality of flexible sheets each having a regular hexagonal peripheral edge defined by six straight edge portions, a front surface adapted to be written on, a rear surface, and a coating of repositionable pressure sensitive adhesive over a portion of said rear surface over the center of the sheet and between opposite straight edge portions releasably adhering said sheet to an underlying sheet in said pad with the straight edge portions of the peripheral edges of said sheets in alignment, and said rear surface of each sheet having two portions free of adhesive adjacent the intersections of the two straight edge portions on both sides of said opposite straight edge portions to afford removal of said sheets from said pad by peeling the uppermost sheet from underlying sheets in the pad, whereby a user may write information on the front surfaces of a plurality of the sheets, remove said plurality of the sheets, and adhere the removed sheets to a planar surface in side by side relationship with straight edge portions of up to six adjacent sheets in contact to represent relationships between the information on the sheets.
Claim 7
Dependent Claim
51 words
A pad according to claim 4 wherein said front surface of said pad has a generally triangular portion adjacent the intersection of two straight edge portions that is visually distinctive with respect to the other portion of the front surface to form a pointer on said front surface at said intersection.
