Abstract
Abstract A walk-in globe for permitting unobstructed viewing of a map of the world which includes a hollow sphere having a diameter substantially greater than that of the height of an adult person. The door provided in the sphere permits access for persons to enter the interior of the sphere. An accurately scaled map of the entire world covers the inner surface of the hollow sphere. In order to support the person within the globe, an elevated support platform is carried therein which supports a person at a height so that the eye level of the person standing on the support platform is substantially at the same level as the center of the sphere. Tracking mechanisms are provided for automatically giving the longitudinal and latitudinal coordinates of a particular location, and for automatically calculating the distances between the various locations shown on the map.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
165 words
A walk-in globe for educational purposes comprising: a hollow sphere large enough to hold a person; means for stationarily supporting the sphere; an accurately scaled map of the entire earth substantially covering the entire inner surface of the sphere; a door mounted on the sphere for allowing entry of a person into the interior of the sphere, so that upon entry of the person into the sphere, the person may view the accurately scaled map of the entire earth a portion of said map being on an inside of said door; an elevated support platform centrally located in said sphere for supporting a person while viewing said map carried on the inner surface of said sphere, said support platform being constructed of transparent material for allowing a person standing on said platform to have a substantially unobstructed view of the earth; whereby a person can obstructively view substantially the entire map so as to readily observe the relative distances between various locations on the map.
Claim 2
Dependent Claim
165 words
A walk-in globe for educational purposes comprising: a hollow sphere large enough to hold a person; means for stationarily supporting the sphere; an accurately scaled map of the entire earth substantially covering the entire inner surface of the sphere; a door mounted on the sphere for allowing entry of a person into the interior of the sphere, so that upon entry of the person into the sphere, the person may view the accurately scaled map of the entire earth a portion of said map being on an inside of said door; an elevated support platform centrally located in said sphere for supporting a person while viewing said map carried on the inner surface of said sphere, said support platform being constructed of transparent material for allowing a person standing on said platform to have a substantially unobstructed view of the earth; whereby a person can obstructively view substantially the entire map so as to readily observe the relative distances between various locations on the map.
Claim 3
Dependent Claim
43 words
The walk-in globe as set forth in claim 1 further comprising: said support platform being carried in said globe so that the eye level of a person standing on said platform is substantially at the same level as the center of said sphere.
Claim 4
Dependent Claim
53 words
The walk-in globe as set forth in claim 1 further comprising: a rotatable location sighting device mounted on the support platform for sighting desired locations on the map; and a coordinate calculating means for assigning the locations on the map located by the rotatable sighting device a longitude coordinate and a latitude coordinate.
Claim 5
Dependent Claim
46 words
The walk-in globe as set forth in claim 3, further comprising a distance computer mounted on the platform for inputting the longitudinal cordinates and the latitudinal coordinates assigned by the coordinate calculating means to the locations and for determining and outputting relative distances between the locations.
Claim 6
Dependent Claim
59 words
The walk-in globe as set forth in claim 3, further comprising: a motorized rotating means connected to the rotatable location sighting device for selectively rotating the rotatable location sighting device; and means carried on the support platform for selectively controlling the motorized rotating means so that the rotatable location sighting device may be selectively rotated to a desired position.
Claim 7
Dependent Claim
30 words
The device as set forth in claim 3, further comprising: a digital readout connected to the coordinate calculating means for displaying the longitudinal and the latitudinal coordinates of the location.
Claim 8
Dependent Claim
60 words
The walk-in globe as set forth in claim 1, further comprising: a rotatable location sighting device mounted on said elevated support at the center of said sphere; and a concentrated light beam source forming part of said sighting device for creating a light beam which indicates the location on said map at which the said rotatable sighting device is pointed.
