Abstract
Abstract A relief sheet segment simulating an original relief structure having a visible pattern thereon, the relief sheet segment having been obtained by printing a plastic sheet with an image and thereafter relief molding the sheet, the printed image having been derived from a planar pattern member obtained by flattening a relief pattern member to obtain a primary master pattern, and the printed image on the relief sheet segment having been normalized to conform closely to the visible pattern on the original relief structure by correcting for distortion introduced by flattening said relief pattern member.

Total Claims: 4
Claim 1
Independent Claim
150 words
In a relief sheet segment simulating an original relief structure having a visible pattern thereon, said relief sheet segment having been obtained by printing a plastic sheet with an image and thereafter relief molding said sheet, said printed image having been derived from a planar pattern member obtained by flattening a relief pattern member to obtain a primary master pattern: the improvement wherein the printed image on said relief sheet segment has been normalized to conform closely to the visible pattern on said original relief structure by correcting for distortion introduced by flattening said relief pattern member and wherein one edge portion of said relief sheet segment has a relief structure and image the same as that of an edge portion of another different relief sheet segment, and whereby the identical edge portions of said segments may be joined in overlapping relation with the images thereof mated without forcible alignment.
Claim 2
Dependent Claim
150 words
In a relief sheet segment simulating an original relief structure having a visible pattern thereon, said relief sheet segment having been obtained by printing a plastic sheet with an image and thereafter relief molding said sheet, said printed image having been derived from a planar pattern member obtained by flattening a relief pattern member to obtain a primary master pattern: the improvement wherein the printed image on said relief sheet segment has been normalized to conform closely to the visible pattern on said original relief structure by correcting for distortion introduced by flattening said relief pattern member and wherein one edge portion of said relief sheet segment has a relief structure and image the same as that of an edge portion of another different relief sheet segment, and whereby the identical edge portions of said segments may be joined in overlapping relation with the images thereof mated without forcible alignment.
Claim 3
Dependent Claim
17 words
A large topographical relief map composed of a plurality of relief sheet segments according to claim 1.
Claim 4
Dependent Claim
43 words
A relief map according to claim 1 having a plurality of loops attached to the back thereof, spaced apart in a horizontal line, and an elongated rod extending through said loops for use as a support member and core for rolling said map.
