Abstract
Abstract A method of manufacturing a raised relief, illuminated globe includes printing a hemispherical map design on a flat vinyl plastic sheet, forming the vinyl plastic sheet into a substantially hemispherical shape, positioning the hemispherically formed sheet in a mold cavity, positioning a mold core on the back side of the sheet, injection molding a styrene backing for the hemispherical shaped sheet to conform the sheet with the mold cavity including relief areas defined in the cavity wall, and removing the molded hemisphere from the mold. A second molded hemisphere is produced in substantially the same manner and is attached to the first hemisphere to form a complete globe. The printed map design of the globe is positioned in the mold cavity to insure that the relief areas are properly positioned with respect to the design.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
A method for forming at least a portion of a globe in relief, comprising, in combination: a. imprinting a flexible, plastic sheet with a predetermined two-dimensional printed pattern; b. stretch-forming said sheet into a generally concave, flexible curved form, said form having an outer surface and an inner surface; c. positioning the stretch-formed sheet in a mold cavity, having a generally concave surface conforming generally to the form of said sheet and including relief areas, with the outer surface of said sheet in opposed relation to mold surfaces defining said cavity; d. subsequently orienting printed areas of said stretch-formed sheet with respect to corresponding said relief areas; e. positioning a mold core in spaced relation to the inner surface; f. subsequently injecting a hardenable material intermediate said inner surface and the mold core and forcing the stretch-formed sheet to deform permanently into the relief areas of the mold defining said mold cavity by pressure of the injection material on the inner surface; and g. hardening said hardenable material to maintain the sheet in a form having relief areas conforming with the mold cavity pattern with said printed pattern substantially in register with said relief areas.
Claim 2
Independent Claim
195 words
A method for forming at least a portion of a globe in relief, comprising, in combination: a. imprinting a flexible, plastic sheet with a predetermined two-dimensional printed pattern; b. stretch-forming said sheet into a generally concave, flexible curved form, said form having an outer surface and an inner surface; c. positioning the stretch-formed sheet in a mold cavity, having a generally concave surface conforming generally to the form of said sheet and including relief areas, with the outer surface of said sheet in opposed relation to mold surfaces defining said cavity; d. subsequently orienting printed areas of said stretch-formed sheet with respect to corresponding said relief areas; e. positioning a mold core in spaced relation to the inner surface; f. subsequently injecting a hardenable material intermediate said inner surface and the mold core and forcing the stretch-formed sheet to deform permanently into the relief areas of the mold defining said mold cavity by pressure of the injection material on the inner surface; and g. hardening said hardenable material to maintain the sheet in a form having relief areas conforming with the mold cavity pattern with said printed pattern substantially in register with said relief areas.
Claim 3
Dependent Claim
11 words
The method of claim 1 wherein said hardenable material is styrene.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein said first portion of a sphere is a hemisphere.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein said sheet is a flexible, vinyl plastic material.
Claim 6
Dependent Claim
17 words
The method of claim 1 including the step of forming a plurality of distinct, but compatible portions.
Claim 7
Dependent Claim
13 words
The method of claim 5 including the step of assembling the distinct portions.
