Abstract

A device for displaying a projected image comprising a housing having a rear projection screen, a projector and a plurality of reflectors. The projector and the reflectors define a projection path that is longer than the depth of the housing.

Claims

1. A device for displaying a projected image comprising:

a housing, said housing comprising a rectangular base having a floor, a major dimension defined by two long sides, and a minor dimension defined by two short sides, said major and minor dimensions being at right angles to each other,

a rear projection screen, said screen being supported along one of the sides of said base and extending in the same direction as said major dimension,

a projector, connection means connected between said projector and said housing for moving said projector relative to said floor,

said connection means comprising a carriage, said carriage supporting said projector so that it projects an image along a projection path that is in the same direction as said major dimension,

said connection means being operative to selectively move said projector transversely of said projection path and parallel to said projection path,

a plurality of reflectors supported in said housing, said plurality of reflectors comprising a first reflector being disposed in the projection path emanating from said projector and being disposed at an angle relative to said projection path so that it changes the direction of said path,

said projector and said reflectors defining said projection path to enable an image emanating from said projector to be projected onto the rear surface of said rear projection screen, and said projection path is longer than the distance between said two long sides.

2. A device for displaying a projected image comprising:

a housing, said housing comprising a rectangular base having a floor, a major dimension defined by two long sides, and a minor dimension defined by two short sides, said major and minor dimensions being at right angles to each other,

a rear projection screen, said screen being supported along one of the sides of said base and extending in the same direction as said major dimension,

a projector, said projector being supported in said housing on said base and being disposed so that it projects an image along a projection path that is in the same direction as said major dimension,

a plurality of reflectors supported in said housing, said plurality of reflectors comprising a first reflector being disposed in the projection path emanating from said projector and being disposed at an angle relative to said projection path so that it changes the direction of said path,

adjustment means connected between said floor and said first reflector, said adjustment means being pivotally connected to said first reflector so that said first reflector can be pivoted relative to said projector,

said projector and said reflectors defining said projection path to enable an image emanating from said projector to be projected onto the rear surface of said rear projection screen, and said projection path is longer than the distance between said two long sides.

3. A device for displaying a projected image comprising:

a housing, said housing comprising a rectangular base, a major dimension defined by two long sides, and a minor dimension defined by two short sides, said major and minor dimensions being at right angles to each other,

a rear projection screen, said screen being supported along one of the sides of said base and extending in the same direction as said major dimension, said screen having a front surface and a rear surface, said rear surface facing the interior of said housing enclosed by said long and short sides and said floor,

a projector, said projector being supported in said housing on said base and being disposed so that it projects an image along a projection path that is in the same direction as said major dimension,

at least first, second and third reflector supported in said housing, said first reflector being disposed in the projection path emanating from said projector and being disposed at an angle relative to said projection path so that it changes the direction of said path,

said second and third reflectors being rectangular, being disposed along said major dimension of said housing and lying in perpendicular relation to said projection path,

a framework for supporting each of said second and third reflectors, each of said frameworks including means defining a pivotal connection for connecting it to the lower edge of its respective reflector so that the angles of said reflectors relative to the projection path can be adjusted so that the image projected by said projector is directed to the rear of said rear projection screen,

said projector and said reflectors define said projection path to enable an image emanating from said projector to be projected onto the rear surface of said rear projection screen, and

said projection path is longer than the distance between said two long sides.
