Shutter system and method
| Details |
Inventors: Hill, George A.;
Assignee:
Primary Examiner: Smith; Creighton
Assistant Examiner:
Attorney, Agent or Firm: Dominik; Jack E.
A shutter system and method in which the shutters are normally rolled to a nominal one foot width and have an infinite length, normally no less than two feet and no more than twelve feet is disclosed. These dimensions can be modified on one foot modules. The shutters are provided with a self-secured panel lock assembly at the overlapping joints on the inside between the shutter and windows normally on two foot spacing vertically. This can be horizontal, however, in other applications. The system includes the utilization of an angle frame at the base, and an overlapping receiver as a header. End caps may be of varying shapes but normally are typical L-shaped angles. The shutters are installed by raising the same upwardly and inwardly to the overhang on the upper header, lowering the same to the point where the lower portion overlap has a keyhole slot, aligning the same, and then manually threading the panel lock assembly in place and the bottom lock screw in place. Where the extrusions of the system are not employed, the threaded members engage a concrete anchor secured in the wall of the structure. |

DETAILED DESCRIPTION What is claimed is: 1.
A shutter panel for use in a shutter system having a header and a footer for receiving a plurality of such shutters, said shutter comprising, in combination: a corrugated body having a central groove and parallel flanking ridges, said groove and ridges comprising an isosceles trapezoidal cross-section; a plurality of ribs longitudinal along said ridges and grooves, extending outwardly therefrom; said panel having lateral edges terminating in a pair of parallel lips; each such lip having a lip bottom and an edge lock angled upwardly from the lip bottom, such that each panel can be overlapped with a like panel along their lips; vertically spaced releasably securable means along the lip bottoms for securing said panel to a like panel that has been placed adjacent thereto and overlapped along the lip; and a laterally spaced releasably securable means for securing said panel to the footer, whereby like panels, when placed adjacent said panel and overlapped along the lips, can be secured both to the footer and to each other to form an interlocked panel system that inhibits wind from getting between the adjacent, overlapped panels.
2.
In the shutter panel of claim 1 above, said vertically spaced releasably securable means comprising: vertically spaced jacknuts permanently affixed to one side of the panel along one of the lip bottoms, said jacknuts being capable of receiving threaded screws; and vertically spaced lock holes along the lip bottom opposite the lip bottom containing said jacknuts, said lock holes being spaced to laterally oppose said jacknuts, whereby like panels, when placed adjacent said panel and overlapped along the lips, can be secured both to each other through the use of threaded screws to form an interlocked panel system that inhibits wind from getting between the adjacent, overlapped panels.
3.
In the shutter panel of claim 1 above, said laterally spaced releasably securable means comprising: laterally spaced keyhole openings for receiving threaded bolts, said openings being spaced along that portion of the panel which is placed adjacent the footer; and said keyhole openings being proportioned to have a diameter of at least 25% more than the bolts to be passed therethrough, whereby threaded bolts can be passed through said openings by a single person without precise alignment, and the panel be thereby secured to the footer, and to any adjacent overlapped panel
