Abstract:
A projection apparatus is disclosed having a first vertical member and a second vertical member disposed parallel to the first vertical member, the second vertical member substantially the same length as the first vertical member. An upper crossbar member is disposed between the first and second vertical members and perpendicular thereto. An intermediate crossbar member is disposed between the first and second vertical members and perpendicular thereto and below the upper crossbar member to define a viewing area bounded by the first and second vertical members, the upper crossbar member and the intermediate crossbar member. A viewing screen is disposed over the viewing area. A mounting member is provided extending over the upper crossbar member and having a mounting end disposed forward of the viewing area a first predetermined distance and a securing end extending rearward of the viewing area a second predetermined distance, the mounting member interfaced to the upper crossbar member in a pivotal manner such that the mounting end is disposed along the length of the viewing area at a predetermined length. A securing device secures the securing end of the mounting member to at least one of the vertical members outside of the viewing area.
