Rolling shutter system with a plurality of single wall slats

摘要

A rolling shutter assembly for covering an opening of a facility. A rolling shutter housing is mounted to the facility and connects with first and second shutter rails. A rolling shutter cover forms part of the rolling shutter housing and contains a rotating axle with a drive mechanism or gear assembly engaging the rotating axle positioned between side caps that close the sides of the rolling shutter cover. A plurality of single wall shutter slats are contained in a rolled up configuration within the rolling shutter housing and deployable to form a protective curtain, with a first single wall shutter slat connected to the rotating axle and additional single wall shutter slats connected in series to the first shutter slat.

主权项

1. A rolling shutter assembly for covering an opening of a facility, wherein the rolling shutter assembly comprises:
a. a first shutter rail; b. a second shutter rail; c. a rolling shutter housing to connect with ends of the first shutter rail and the second shutter rail, the rolling shutter housing comprising:
(i) a rolling shutter cover with a first end and a second end opposite the first end;(ii) a first side cap mounted on the first end of the rolling shutter cover;(iii) a second side cap mounted on the second end of the rolling shutter cover;(iv) a drive mechanism attached to one of the rolling shutter housing side caps and an idler attached to the other rolling shutter cover side cap opposite the drive mechanism; and(v) a rotating axle contained in the rolling shutter cover and attached between the driving mechanism and the idler; and d. a plurality of interlocking and pivotally interconnecting curved single wall shutter slats adapted to be contained within the rolling shutter cover, wherein a first single wall shutter slat is connected to the rotating axle with a connecting mechanism for positioning the first single wall shutter slat away from the rotating axle, and wherein additional single wall shutter slats are connected in series to the first single wall shutter slat, and each single wall shutter slat comprises an integral structure having:
(i) a slat body with a curved front side and a curved back side;(ii) a top hook portion on a first end of the curved back side, the top hook portion comprising:
1. a ledge section with a ledge;2. a top hook with a hook end forming a second cavity; and3. a hook section comprising:
i. a curved wall forming a central cavity;ii. an extending lip extending from the curved wall on an outer side;iii. a reinforced section between the curved wall and the top hook, wherein the top hook comprises a hook end extending towards the ledge section with the second cavity generally opposite the central cavity; andiv. an opening formed between the hook end and the ledge;(iii) a bottom receptacle portion for holding the top hook portion of an adjacent single wall shutter slat, wherein the bottom receptacle portion comprises a counter wall with a counter wall end opposite a bottom hook with a bottom hook end forming a bottom cavity with a bottom opening between the counter wall and the bottom hook;(iv) the top hook portion is adapted to slide into the bottom receptacle portion of the adjacent single wall shutter slat to pivotally engage between the bottom hook and the counter wall allowing the counter wall end to contact and transfer load to the extending lip and the bottom hook to contact and transfer load to the ledge; and(v) an alignment device disposed proximate or over the central cavity for aligning the first single wall shutter slat with the additional single wall shutter slats in the central cavity; and wherein the single wall shutter slats connect in series for first moving from a rolled up orientation to a curtain orientation over the opening using the drive mechanism forming a gap-less protection wall over the opening, and then second moving from the curtain orientation to the rolled up orientation within the rolling shutter cover.
