Abstract
A rolling shutter assembly is formed of a plurality of shutter slats which are designed to fit snuggly against each other when in a rolled up state so as to substantially reduce the diameter of the rolled up shutter assembly. This reduction of the diameter of the shutter assembly permits the use of a smaller housing for the shutter assembly. The smaller housing increases the aesthetic appeal of the assembly and decreases the material required for the assembly housing and thus the cost of the shutter assembly. The rolling shutter assembly includes a shutter support member, a shutter coupled to the support member and a plurality of tracks the guide the shutter while it is being raised or lowered. The shutter slats include a hinge connection along each edge portion of the slats.
Claims6
A retractable rolling shutter assembly operable between a deployed condition and a stored condition comprising;
- a shutter support member;
- an initial discrete shutter subassembly having a plurality of individual slats in mechanical engagement with one another;
- said initial discrete shutter subassembly having a length effective to essentially encircle said shutter support member when stored thereabout;
- at least one subsequent shutter subassembly having a plurality of individual slats in mechanical engagement with one another;
- each of said slats having a body portion, a top edge extending along a top portion of said body portion, a bottom edge extending along a bottom portion of said body portion;
- a top connecting element connected to said top edge;
- a bottom connecting element connected to said bottom edge;
- said top connecting element of one of said slats being connected to said bottom connecting element of another of said slats thereby forming a joint;
- the distance between said top and said bottom connecting elements of each said slat define a height of said slat;
- each of said slats in each said shutter subassembly has the same height and the height of said slats in different shutter subassemblies is different from the height of said slats in other subassemblies;
- the height of said slats in said shutter subassemblies increases as the distance from said shutter support member to said shutter subassembly increases;
- said at least one subsequent shutter subassembly having a length effective to essentially encircle said initial or previously deployed discrete shutter subassembly in its stored condition, whereby each said shutter subassembly nests upon said previously deployed shutter subassembly when said shutter subassemblies are in their stored positions and said joints of said shutter subassembly being juxtaposed but not overlapping corresponding joints of said previously deployed shutter subassembly thereby decreasing the overall dimensions of said rolling shutter assembly;
- said body portion of said slats of each said shutter subassembly are in contact with said body portion of said slats of said previously deployed shutter subassembly when said rolling shutter assembly is in its stored position.
