Abstract

1388661 Globe I J STARWORTH 13 June 1972 27502/72 Heading G5G A hollow sectional spherical globe made of deformed sheet material comprises two spheresegment polar end members 11, and a plurality of spherical segment side members 12 which together with the end members are assembled into a spherical globe with said end members defining the polar regions, the side members having longitudinal edges all of which are in planes of great circles of the globe passing through the poles, and latitudinal edges following a circle of latitude of the globe, a plurality of notched tongues 19 on the longitudinal edges of each side member, each of said notched tongues on a single longitudinal edge facing in the same direction, said notched tongues interlocking with oppositely disposed notched tongues on the matching longitudinal edge of the next side member to ensure exact register of the side members when they are fully seated by rotation in the plane of their matching edges, and means such as adhesive tape 21 bridging the edges of both side members to lock the registered pieces in position against retrograde movement out of register, means such as slots 17 on the latitudinal edges of the side members to attach the side members to the adjacent polar end members, means such as tongues 15 on the polar members to attach them to said means on the corresponding edges of the side members to complete the globe, all these attaching and locking means being disposed on the inside surface of the globe, a polar axis member 13 passing through said end members of the assembled globe and locking members 25 on the polar axis member co-operating with said polar end members to lock the assemblage into place. The globe may be suspended as shown in Fig. 2, or it may rest in a concave base. Each side member may comprise two parts joined at their equatorial edges; there may be twelve such parts, as shown, in Fig. 2. Alternatively, there may be four side members, each covering 90 degrees of arc. The sections of the globe are printed flat, and then deformed to the appropriate shape. They are made of thin sheet metal, or thermoplastic resins. The sections may be nested when the globe is dismantled and stacked in a rectangular box.
