Portable projector and screen mounting system

Abstract

A portable projection screen system includes a structure defining a viewing area. A projector mounting assembly includes first and second mounting arms spaced a selected distance apart. Each of the first and second mounting arms including a horizontal projector member located above the viewing area and extending forward of the viewing area. A vertical projector member pivotally connects to a backside of the viewing area in a plurality of positions. Each of the plurality of positions locates the horizontal projector member at a different height above the viewing area. A projector crossbar member connects and moves between a plurality of positions that are each a different distance from the viewing area.

What is claimed is: 
     
         1 . A portable projection screen system, comprising:
 a first vertical member including at least one hinged point for folding the first vertical member into at least two separate portions;   a second vertical member including at least one hinged point for folding the second vertical member into at least two separate portions, the second vertical member disposed parallel to the first vertical member and having substantially the same length as the first vertical member;   a first horizontal member disposed perpendicular to and pivotally connected with the first and second vertical members including at least one hinged point for folding the upper horizontal member into at least two separate portions;   a second horizontal member disposed perpendicularly and pivotally connected with the first and second vertical member including at least one hinged point for folding the second horizontal member into at least two separate portions and located below the first horizontal member to define a viewing area bounded by the first and second vertical members and the first and second horizontal members;   a projector mounting assembly comprising:
 a first and second mounting arms spaced a selected distance apart, each of the first and second mounting arms including a horizontal projector member located above the first horizontal member and extending forward of the viewing area and a vertical projector member pivotally connected perpendicular to the horizontal projector member, wherein the vertical projector member connects to a backside of the viewing area in a plurality of positions, each of the plurality of positions locating the horizontal projector member at a different height above the first horizontal member; and 
 a projector crossbar member slidably connected between the first and second mounting arms to which a projector is mounted, wherein the projector crossbar member slides between a plurality of positions, each of the plurality of positions a different distance from the viewing area. 
   
     
     
         2 . A portable projection screen system, comprising:
 at least four members interconnected to define a viewing area bounded by the four members;   a projector mounting assembly comprising:
 a first and second mounting arms spaced a selected distance apart, each of the first and second mounting arms including a horizontal projector member located above a first one of the members and extending forward of the viewing area and a vertical projector member pivotally connected perpendicular to the horizontal projector member, wherein the vertical projector member connects to a backside of the viewing area in a plurality of positions, each of the plurality of positions locating the horizontal projector member at a different height above the first member of the at least four members; and 
 a projector crossbar member connected between the first and second mounting arms to which a projector is mounted, wherein the projector crossbar member moves between a plurality of positions, each of the plurality of positions a different distance from the viewing area. 
   
     
     
         3 . A portable projection screen system, comprising:
 at least four members interconnected to define a viewing area bounded by the four members;   a projector mounting assembly comprising, wherein the projector mounting assembly connects to a backside of the viewing area in a plurality of positions, each of the plurality of positions locating the projector mounting assembly at a different height above the first member of the at least four members and further wherein the projector mounting assembly defines a mounting location for a projector, the mounting location moving between a plurality of positions, each of the plurality of positions a different distance from the viewing area.   
     
     
         4 . A portable projection screen system of  claim 3  further comprising:
 at least one base member pivotally connected to a base end of at least one member of the at least four members, the at least one base member pivoting between a first position parallel to the at least one member of the at least four members and a second position perpendicular to the at least one member of the at least four members; 
 an adjustable foot extender, the adjustable foot extender further comprising: 
 a pair of side plates for pivotally connecting to lateral sides of the at least one base member; 
 a stability plate connected between the pair of side plates and extending outward from the at least one base member to stabilize the portable projection screen system, wherein the stability plate may pivot from positions both above and below a central axis of the at least one base member; 
 a securing arm extending from a top surface of the at least one base member and including a threaded opening; 
 a securing bolt within the threaded opening that when rotated in a first direction a first end of the securing bolt engages the stability plate to pivot the stability plate below the central axis of the at least one base member and when rotated in a second direction enables the stability plate to pivot above the central axis of the at least one base member.
