Benefits of technology
"This invention is a narrow elongated opening for a movie screen that can be attached to the ceiling of a room and completely retracted when not in use. The opening has a unique shape that fits with the design elements of the Adams drop ceiling. The screen opening is formed by two short square-U-shaped end pieces that connect two long parallel sides. The long rails have inner edges that slope upwardly and inwardly towards the center of the opening. The new clip is longer, wider, and easier to install, providing enough securing strength to attach the drop ceiling to an existing T-rail on one side only."
Problems solved by technology
However, this poses a problem not heretofore addressed in the prior art, since the drop ceiling is not strong enough to support the screen and retracting mechanism and the actual ceiling is not accessible through the drop ceiling.
The full-time visual presence of the movie screen lessens the aesthetic value of the drop ceiling.
In addition, the presence of a drop ceiling poses certain problems, such as the stability of the screen if it is not attached directly to the actual ceiling of the room.
One other drawback in the prior art Adams drop ceiling is the attaching clip used.
The older clip was short and required a great amount of pressure (approximately 28 pounds of force).
These functional features of the prior clip made the clip difficult to attach.

Embodiment Construction
[0021]The normal type of metal T-rail drop ceiling system is shown in FIG. 1 and 2. This type of T-rail system involves a T-rail 1, wire hangers 2 and ceiling hooks. The T-rail 1 is inverted as shown in FIG. 2. The T-rail is attached to the actual ceiling of a room by means of a wire 2. The upper portion of the wire 2 is attached to the actual ceiling while the lower portion of the wire 2 is attached to the T-rail. The T-rail is initially designed to support a drop ceiling tile for the standard drop ceiling system.
[0022]This prior Adams drop ceiling system invention utilizes the existing T-rail system and T-rails 1 but also attaches grooved wooden ceiling tile supports 3 to the existing inverted T-rail by means of attaching clips.
[0023]The grooved ceiling tile supports have a unique shape so as to be adaptable to attachment to the inverted existing T-rail 1. At the intersection of the rails 3 and cross-rails 3′ are transition square blocks 4. These blocks have a shape similar to the...

A perimeter for a screen opening in a wooden drop ceiling has two parallel long sides connected by left and right end caps. The longs sides and end caps form a narrow screen opening for raising and lowering a movie or video screen attached to the original ceiling of the room. The long sides have approximately three foot lengths connected by transition blocks to form the long perimeter sides. The inner edges of the long sides, transition blocks and end caps are all tapered identically to slope inwardly toward the screen opening and upwardly toward the ceiling. The slope tends to narrow the perceived opening to make it more attractive to the eye. The entire screen opening perimeter system is easily attached to an existing metal T-rail drop ceiling by clips approximately three-fourths to an inch long, three thousandths of an inch thick and having a gap of approximately 0.242 inches. The clips require only approximately 7.8 pounds of force to attach the screen perimeter to the T-rail system.
Description
[0001]This invention relates to the field of indoor drop ceilings and more particularly to a narrow functional screen opening for a drop ceiling.[0002]It is common in the building trades to replace an existing ceiling with what is called a “drop ceiling”. These drop ceilings utilize wire hangers which are attached to the existing ceiling or joints. The other end of the wire hangers are attached to various lightweight metal T-rails. A system of intersecting inverted T-rails is then installed below the regular ceiling. Once this system of intersecting T-rails is installed, ceiling tiles are placed in the square or rectangular patterns thus created to provide a new lower ceiling. In many applications, a retractable screen is suspended from the original ceiling. However, this poses a problem not heretofore addressed in the prior art, since the drop ceiling is not strong enough to support the screen and retracting mechanism and the actual ceiling is not accessible through the drop ceilin...
