Abstract:
A globe stand construction for mounting a globe from a single support arm for rotation about a polar axis and an equatorial axis simultaneously, comprising, in combination;a base; a single arcuate mounting arm extending from the base upwardly to an axial connection point; a mounting pin fixed to the connection point of the mounting arm and projecting over the base; a first hemisphere with a first pole and a first equatorial rim; a second hemisphere with a second pole and a second equatorial rim; a polar pin connecting the poles and spacing the equatorial rims in opposed relation; and a polar pin bushing member having a polar through passage with the polar pin extending therethrough, said bushing member also including a single mounting pin connection, said polar pin and said mounting pin each rotatably connected to the bushing member for simultaneous rotation of the globe about a polar axis and an equatorial axis, said mounting pin supporting the hemispheres over the base, whereby the hemispheres are counterbalanced by the base, said bushing member comprising a generally circular plate having an outside rib positioned between the first and second hemispheres, and said bushing member further including a radial mounting pin passage with bushings therein, said mounting pin passage extending from the outside rib toward the polar through passage, said mounting pin seated on spaced bushings in the mounting pin passage and including a detent element for retaining the mounting pin in the mounting pin passage, said rib defining an equatorial axis and said polar pin defining a polar axis at right angles thereto and centered on said circular plate.
