Accordion shutter system
| Details |
Inventors: Knezevich, Vladimir John;
Assignee:
Primary Examiner: Smith; Creighton
Assistant Examiner:
Attorney, Agent or Firm: Lott & Friedland, PA
An accordion shutter system comprising a plurality of continuously extruded, substantially rectangular accordion shutter blades having opposing vertical sides wherein one vertical side of each the shutter blade consists of a male end and the opposite vertical side of each the shutter blade consists of a female end such that the male end of adjacent the shutter blades interlocks with the female end of the shutter blade therein forming a triple interlocking hinge; means for laterally deploying and stacking the accordion shutter system; means for connecting the shutter blades to each other when the accordion shutter system is fully deployed; and means for connecting the shutter blades to a horizontal or vertical surface. The male end of the triple interlocking hinge comprises a male partial circle and the female end comprises a female partial circle wherein the male partial circle is smaller in diameter than the female partial circle and the male partial circle has two outward protruding exterior hooks on its outer periphery that fit inside the female partial circle and wherein the male partial circle has a notch that protrudes from an offset arm of the male end. |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An elevation of the accordion shutter system which embodies this inventions is shown in FIG.
1.
The accordion shutter system is made up of a plurality of interlocking blades 29 riding in and guided by an elongated header 25 and an elongated adjustable sill assembly 26 & 45.
The system includes an optional, 90 degree starter strip 28 at one side and an optional, 180 degree starter strip 27 on the other side.
The shutter system is held together by elongated and interlocking, male centermate 32 and a female elongated and interlocking centermate 31 held together by a mechanical lock 30 and or locking pins that slide in elongated slots 38 and 38A that can best be seen in FIG.
2.
These locking pins are round aluminum rods that slide into the elongated header 25 and into the top section of the bottom sill 26, again as seen in FIG.
2.
FIG.
2 shows the shutter blade 29 with its male 36 and female 35 ends, interlocked.
This interlocking of accordion blade ends, creates the hinge mechanism that allows this shutter system array to vary in width as may be required.
The deployed shutter system across an opening, appears as a sinusoidal pattern when seen as a plan view from above, as in FIG.
2.
The screws 48 and 48A, that connect each interlocking shutter blade to another and provide the follower mechanism that allows the shutter system when being deployed or stacked, to follow the grooves 46 and 47 shown on FIG.
3.
Screw 48, installed through the trolley assembly 40, tube 41A, washer 76 and into part 34 of the male end of the hinge 36.
This holds the trolley assembly 40 to the elongated interlocking shutter blades 29 at every other blade hinge 35.
Every other blade hinge 35 following a groove 46, 47, 46A, 63, 63A in a track (header 25,43 or sill 25,26,44) has simply a guide pin composed of a 1/4" diameter screw 48A and nylon or plastic hollow tube 41,41A and washer 76.
The trolley assembly 40 carries the weight of the shutter in the header 25 and allows ease of movement in either of two directions, when deploying or stacking shutter system
