US 6,095,225 A · Shutter slat with integrated screw boss

Abstract

The present invention is directed to a rolling protective shutter having slats with integrated screw bosses formed in their hinges. Each slat includes a first elongated socket along one edge of the slat, and a second elongated socket along the opposite edge of the slat. The hinges of the shutter curtain are formed by pivotally disposing the second elongated socket of one slat within the first elongated socket of an adjacent slat. After the shutter curtain is assembled, alignment/retention members are attached to either end of the second elongated socket to keep the slats substantially vertically aligned and retained within the side tracks. The alignment/retention members engage the adjoining slats to prevent substantial relative movement of the interconnected slats, and are dimensioned so that the alignment/retention members do not extend beyond the surfaces of the slats. Consequently, the shutter curtain may be tightly rolled onto the shutter support member without interference from the alignment/retention members.

Dependent claims

A rolling shutter assembly, comprising:

a shutter support member;
a shutter coupled to said shutter support member, said shutter comprising a plurality of individual slats and a plurality of hinges interconnecting said slats;
a first extension member coupled to one of said hinges and being adapted to engage said slats interconnected by said one of said hinges to prevent substantial relative horizontal movement of said interconnected slats;
and
a pair of shutter tracks, said shutter and said shutter support member being adapted to roll said shutter from an unrolled position in which said slats are disposed in said shutter tracks to a rolled position in which said shutter is rolled up on said shutter support member, wherein said first extension member is disposed within one of said shutter tracks when said shutter is in said unrolled position, said one of said shutter tracks being adapted to engage said first extension member to retain said first extension member and said shutter in said one of said shutter tracks when said shutter is in said unrolled position.
