Definitions

  • the invention relates generally to systems for covering and securing openings within buildings such as windows or doors. More particularly, embodiments of the invention include shutter systems that protect building openings during intense periods of weather and/ or secure building openings at other times.
  • Businesses and homes include one or more doors, and often are designed with one or more windows for the benefit and pleasure of building occupants.
  • doors, windows, and other openings in a building provide points of vulnerability within an otherwise sound structure. Damaging winds, flying debris, and falling objects present a threat to people within the structure because they often damage or break windows and doors, strewing glass about, and hurtling projectiles through windows, doors, or other openings in the structure.
  • Securing retail stores and other buildings is traditionally accomplished by using steel roll down shutters, chain link gates, sliding door panels, and other closure techniques.
  • This kind of security creates several undesirable circumstances. For example, it is no longer possible for shopkeepers or other businesspeople to show their merchandise to the passing public. There is a desire to show their merchandise and display product models even when the shop is closed. In addition to product display, advertising opportunities and information display are also important. Naturally, shop windows, doorways, and other openings create an opportunity to achieve this advertising. Unfortunately, it is not possible to use in-store advertising systems like narrowcasting, posters or banners when security means, e.g., closed shutters, cover the displayed information. Further, the closed shutters or gates create an unfriendly atmosphere.

  • the shutter system comprises a plurality of panels wherein each of the panels comprises a slat along with a top hinge member and a bottom hinge member.
  • the top and bottom hinge members of adjacent slats connect to form hinge assemblies that reinforce the slats and strengthen the shutter against breaking.
  • the top and bottom hinge members reinforce the slats in order to provide a wider shutter with longer slats.
  • the hinge assemblies allow the panels to roll up around the torque tube within the housing and unwind.
  • the slats may comprise a polycarbonate material to provide enough strength to the system for example to withstand high winds, flying debris, and falling objects caused by severe weather.

  • the method further includes mounting the housing adjacent a top of the opening and mounting the first and second side rails adjacent sides of the opening to receive the shutter as it rolls up and down.
  • the method also includes mounting at least one storm bar adjacent the shutter between the first and second side rails and extending from the top end of the shutter to the bottom end of the shutter for reinforcement.
  • FIGS 8 and 9 illustrate another aspect of the shutter 20 according to some embodiments. While panels with non-opaque slats can advantageously provide for light transmission into and out of a building, the hinge assemblies 51 connecting adjacent slats 22 can decrease the available viewing area of the shutter 20.
  • each hinge assembly 51 includes a top hinge member 52 and a bottom hinge member 53 as previously described, which in many cases are manufactured from an aluminium alloy.
  • a shutter 20 with a viewing area frequently interrupted by the hinge assemblies can be aesthetically unappealing and hinder the ability of, for example, customers to view into a store window.
  • the height of the slats 22 can be varied to provide a square roll-up feature.
  • the slats 22 increase in height, h, from the top 19 of the shutter to the bottom 21 of the shutter.
  • a top slat 54 can have a height, h, of about 5.12" while a base slat 56 can have a height, h, of about 9.40".
  • the progressively increasing size of the slats 22 allows the panels 58 to wrap around the torque tube 60 in a square like fashion, each panel 58 directly overlapping another panel 58.
  • straps 61 and a storage bumper 62 can be included in some embodiments to further align the panels 58 as they begin to roll up. Because each winding around the torque tube 60 only requires four hinges 51, a greater area is available for the viewing slats than for a configuration requiring a greater number of hinges 51 to wind up in a more cylindrical fashion.
  • displaying information and advertisements in windows, doors, and other openings may be desirable features, especially for shopkeepers. While non-opaque, such as transparent, slats can allow viewing through a shutter, it can be desirable to present information more directly to people viewing the shutter. For example, in the presence of severe weather, shopkeepers may wish to display weather related information, such as weather warnings, emergency information, or modified store hours. In other cases, it can be advantageous to present advertisements to passersby when the shop is closed due to weather related activity or otherwise. Or, as previously described, managers of larger facilities, such as airports, may wish to use a shutter system with a projection system.
  • FIG. 10 illustrates a shutter system 70 combined with a projection system 74 according to some embodiments of the invention.
  • the shutter system generally includes a shutter 71 with a plurality of projection panels 72.
  • the projection panels 72 also operate to securely close off an opening (e.g., a window or doorway), thus providing a secure building.
  • Storm bars are included to strengthen the shutter, but may be removed when not needed to provide an unobstructed view. In other embodiments, storm bars are not used.
  • the projection panels 72 each have a slat and top and bottom hinge members similar to embodiments previously described.
  • the slat comprises a nontransparent.( e.g. milky white) polycarbonate material having diffusion properties capable of transferring a display image projected at one side such that is can be seen when viewing the material from the opposite side.
  • the polycarbonate allows as little as 4% light transmission with a diffusion factor of about 0.8.
  • the polycarbonate material is solidly constructed and provides an adequate level of protection from severe weather and theft deterrent as it encloses the building windows, doors, and other openings.
  • the polycarbonate material has strength characteristics similar to the Lexan polycarbonate, type 9030 already discussed. While one possible material for the projection panels 72 has been described, it will be appreciated by those skilled in the art that other materials having similar properties may also be employed.

  • an in-store display 80 can be coupled to the PC 78 for in-store narrow casting or displaying information identical to that displayed on the projection panels 72.
  • projection system 74 includes PC 78 connected via various connections to projector 76 and a display unit 80. More specifically, PC 78 is connected to a VGA splitter 82, which can then provide signals to both projector 76 and display 80.
  • VGA splitter 82 can then provide signals to both projector 76 and display 80.
  • certain components may also be added including a network switch 84 and optional image input devices 86, such as cameras.
  • Each of these components are connected via appropriate connection methodology such as CAT5 network cables, VGA cables, USB cables, UTP or fire wire cables etc.
  • appropriate connections and connection methodologies provide certain advantages in the right situations. For example, a wireless connection methodology may be advantageous in certain situations. In place of VGA other cables like VGA, DVI, HDMA may be used.
  • FIG. 12 provides one illustration of an implementation where multiple shutter systems are used. As shown, appropriate network connections are provided so that image data on a content server 88 is accessible by multiple PCs 78 at each of the multiple locations. More specifically, a first location 90, a second location 92, a third location 94, and a fourth location 96 are all illustrated in Figure 12. Each of these locations can include the components outlined above and shown in Figure 11. In addition, each location includes a network router 98 connected to content server 88 through a network 100, e.g., through an Internet connection.
