Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 103 words
A device for supporting and continuously moving a television screen, a stationary enclosure having a generally rectangular shape, a platform including a plurality of wheels for supporting a television screen, tracks along two sides of said enclosure extending from front to rear providing support for said moveable platform, said wheels rolling along said tracks, means positioned within said enclosure for reciprocally moving said platform in a linear path so as to place a television screen positioned on the platform at different angles and distances from the eye of the viewer at different intervals of time, said wheels being rotated by said moving means.
Claim 2
Independent Claim 103 words
A device for supporting and continuously moving a television screen, a stationary enclosure having a generally rectangular shape, a platform including a plurality of wheels for supporting a television screen, tracks along two sides of said enclosure extending from front to rear providing support for said moveable platform, said wheels rolling along said tracks, means positioned within said enclosure for reciprocally moving said platform in a linear path so as to place a television screen positioned on the platform at different angles and distances from the eye of the viewer at different intervals of time, said wheels being rotated by said moving means.
Claim 3
Dependent Claim 71 words
The structure of claim 1 further characterized in that said means for moving said platform includes a reversible electric motor, a power transfer box and a bearing supported shaft, said power transfer box converting rotational energy of said electric motor to rotation of said bearing supported shaft, said bearing supported shaft connected to said wheels, said wheels rotated by said bearing supported shaft, said wheels moving said platform along said tracks.
Claim 4
Dependent Claim 43 words
The structure of claim 1 further characterized in that the enclosure includes reversal trigger switches, said reversal trigger switches mounted on the front and back inside surfaces of said enclosure and determining the direction of rotation of the means for moving said platform.
Claim 5
Independent Claim 81 words
A device for supporting and continuously moving a television screen including a platform for supporting a television screen, means for moving said platform in a circular periodic path, means for maintaining the orientation of the TV screen positioned on the platform essentially in a single direction, irrespective of movement of the platform, as the platform is moved in said circular periodic path, whereby a viewer, in a stationary position, can view the TV screen as it is moved in said path.
Claim 6
Independent Claim 81 words
A device for supporting and continuously moving a television screen including a platform for supporting a television screen, means for moving said platform in a circular periodic path, means for maintaining the orientation of the TV screen positioned on the platform essentially in a single direction, irrespective of movement of the platform, as the platform is moved in said circular periodic path, whereby a viewer, in a stationary position, can view the TV screen as it is moved in said path.
Claim 7
Dependent Claim 34 words
The structure of claim 4 further characterized by and including a stationary enclosure, means on said enclosure providing support for said movable platform, the means for moving said platform being positioned within said enclosure.
Claim 8
Dependent Claim 45 words
The structure of claim 4 further characterized in that the said enclosure is a generally cylindrical shape, said enclosure on its top surface supporting a large turntable, said large turntable being free to rotate and whose diameter is larger than the diameter of said enclosure.
Claim 9
Dependent Claim 57 words
The structure of claim 6 further characterized in that said large turntable supports at its outer edge and above its surface a platform, said platform rotates freely about its own axis and supports the television screen, said platform supported by a gripping shaft axle, said gripping shaft axle mounted in said large turntable but free to rotate.
Claim 10
Dependent Claim 56 words
The structure of claim 7 further characterized in that said large turntable includes means for counter-balancing the weight of said platform and a T.V. set positioned on said platform, said means for counter-balancing including a counterweight, said counterweight mounted on said large turntable diametrically opposed to the mounting of said gripping shaft axle of said platform.
Claim 11
Dependent Claim 117 words
The structure of claim 7 further characterized in that said means for moving said platform includes an electric motor, a power transfer box connected to sAid electric motor, a drive shaft connected to said power transfer box and a drive arm connected to said drive shaft, said power transfer box converting the rotational energy of said electric motor to rotation of said drive shaft, said drive shaft rotation converted to angular motion of said drive arm around the outer edge of said cylindrical enclosure, said drive arm causing said gripping shaft axle to move around the outer edge of said cylindrical enclosure, said gripping shaft axle moving said platform around the outer edge of said cylindrical enclosure.
Claim 12
Dependent Claim 105 words
The structure of claim 9 further characterized in that said platform is rotated about its own axis by said gripping shaft axle, said gripping shaft axle being rotated by sprocket means, said sprocket means including a first sprocket attached to said gripping shaft axle, a second sprocket mounted to the fixed surface of the top of said enclosure at the center of said enclosure and a continuous chain connecting said first and second sprockets, said sprocket means maintaining a fixed angular orientation of said platform with respect to the original axis of said platform as the platform travels about the outside edge of said enclosure.
Claim 13
Dependent Claim 169 words
The structure of claim 10 further characterized in that said enclosure includes an electrical power outlet and means for supplying electrical power to a T.V. screen positioned on said platform, said electrical power outlet mounted on said platform, said means for supplying electrical power including two pairs of slip-rings and brushes, a plurality of electrical cords, and a plug, said first pair of slip-rings and brushes located at the junction of the said driving arm and said gripping shaft axle, a first piece of said electrical cord routed between said first slip-ring and said electrical power outlet, said second pair of slip-rings and brushes located at the junction of said drive arm and said drive shaft, and a second piece of electrical cord routed between said second slip-ring and said first brush, a third piece of electrical cord routed from the said second brush to the outside of the device, said third piece of electrical cord connected to a plug, said plug suitable for connecting to external power means.
