DETAILED DESCRIPTION

(12) FIG. 1 is a front view of an embodiment of an upward acting sectional door 100 in which an impact rated window frame assembly 102 is employed to advantage. In the embodiment illustrated in FIG. 1, the upward-acting sectional door 100 is rated for areas prone to receive hurricane force winds while still providing the ability for persons to view through window assemblies 102. As illustrated, the door 100 includes a plurality of panels that together form a front face 104 and enclose an opening 106 in a building 108 or other structure. In the embodiment illustrated in FIG. 1, for example, the door 100 includes a number of panels, namely, a top panel 110, a plurality of intermediate panels 112 and a bottom panel 114 that enclose the opening 106 defined by two jambs 116, 118, a header 120 and a driveway or other bottom surface 122. In some embodiments, the panels include one or more openings 172 for receiving the impact rated window frame assemblies 102, as discussed in greater detail below. It should be understood that although all of the top panel 110, the intermediate panels 112, and the bottom panel 114 have multiple openings 172 as illustrated in FIG. 1, in other embodiments, one or more of the panels 110, 112 and/or 114 may be formed without any openings 172. According to some embodiments, the openings 172 are separated by non-deformed planar surfaces 148 that form the front faces 104 of the panels 110, 112 and 114.

(13) Referring to FIG. 2, the panels 110, 112 and 114 are hingedly connected and mounted on conventional track and rollers 130 to enable movement of the door 100 between a vertical (closed) position shown in FIGS. 1 and 2, and a horizontal (i.e., open or overhead) position.

(14) Referring specifically to FIGS. 3 and 4, the impact rated window frame assembly 102 includes a decorative frame 310, an exterior frame 320, an interior frame 340 and a shield member 330. In the embodiment illustrated in FIGS. 3 and 4, the shield member 330 is sandwiched between the interior frame 320 and exterior frame 340, which securely clamp the assembly 102 onto the planar portion 148 of the door 100 via a plurality of fasteners 350 extending through exterior frame 320, shield member 330 and interior frame 340.

(15) With reference to FIGS. 4 through 6, the decorative frame 310 includes a body 510 formed having an inner surface 530 and an outer surface 532. According to some embodiments, the inner surface 530 is recessed and/or otherwise configured to form a cavity 534 to receive and mate with at least a portion of the exterior frame 320. In the embodiment illustrated in FIG. 5, a slot 522 is oriented such that a slot opening 524 forms a passageway into and otherwise faces the cavity 534 to receive an extrusion 620 formed on the exterior frame 320, as discussed in greater detail below.

(16) With continued reference to FIG. 5, a groove 536 is formed near a first end 518 for receiving a seal 512 therein and a second groove 538 is formed near a second end 520 for receiving a seal 514 therein, for sealing the window frame assembly 102 within the panel opening 172. In the embodiment illustrated in FIG. 5, the second end 520 further includes an inner frame section 516 that frames and otherwise borders the shield member 330. According to some embodiments, the inner frame section 516 is sloped downwardly toward the shield member 330 to frame or otherwise provide an aesthetically pleasing transition toward the shield member 330.

(17) Referring now to FIGS. 4, 6 and 7, the exterior frame 320 is formed having a body portion 610 having a top surface 622, a bottom surface 640 and an extension 620 extending from the body portion 610 for insertion into the slot 522 of the frame 310. As discussed in greater detail below, the cooperative engagement of the extrusion 620 within the slot 522 secures the frame 310 to the frame assembly 102, and thus, to the sectional door 100.

(18) According to some embodiments, the body 610 includes a threaded opening 630 for receiving the fastener 350 (FIG. 4) to secure the exterior and interior frames 320 and 340 together. In that regard, the interior frame 340 includes a corresponding opening 730 such that when the interior frame 340 is aligned with the exterior frame 320, the opening 730 is co-axially aligned with the threaded opening 630 to receive the fastener 350 therein. In one embodiment, the opening 730 is a through hole and the fastener 350 passes through the opening 730 to engage with and otherwise be secured within the threaded opening 630. When the fastener 350 is tightened, the interior frame 340 and the exterior frame 320 are pulled toward each other to create a compressive load acting on the planar surface 148. As a result, the exterior frame 320 and the interior frame 340 secure the frame assembly 102 onto the sectional door 100 by clamping onto the planar surface 148. In the embodiment illustrated in FIGS. 3 and 4, the fastener 350 is a screw; however, it should be understood that fastener 350 may be substituted with other types of fasteners performing the same function. Additional and/or alternatively, the fastener 350 may include an adhesive, for example, to secure the exterior and interior frames 320 and 340 together.

(19) With continued reference to FIGS. 4, 6 and 7, the exterior frame 320 further includes a raised edge or extension 650 for abutting against a corresponding raised edge or extension 750 of the interior frame 340. The extensions 650 and 750, when aligned and otherwise abutting each other as illustrated in FIG. 4, define a space between surfaces 640 and 740 to receive and otherwise enclose the shield member 330. Referring specifically to FIGS. 4 and 7, the interior frame 340 includes an arm member 752 extending from the body 710 and terminating at an end 754 to contact and otherwise abut the planar portion 148 of the sectional door 100. In the embodiment illustrated in FIG. 7, for example, the end 754 is formed having a planar surface configured to contact and otherwise abut the planar portion 148 of the sectional door 100 to prevent the frame assembly 102 from detaching from the door 100. In FIGS. 4 and 7, the arm member 752 extends angularly from the body 710 to contact the planar portion 148 and is generally straight; however, it should be understood that the arm member 752 may be otherwise configured. For example, the arm member 752 may be curved, may extend at different angles, may have a different thickness so long as the arm member 752 contacts the planar portion 148 to resist detachment of the frame assembly from the door 100. In some embodiments, the exterior frame 320 and the interior frame 340 include hollow compartments such as compartments 720 for saving material and/or reducing component weight, for example. It should be understood that the size, shape and number of hollow compartments 720 can vary depending on the desired configuration, size and weight of the frame assembly 102.

(20) FIG. 8A is a front view and side view, respectively, of the shield member 330 of the frame assembly 102 of FIG. 3. According to embodiments disclosed herein, the shield member 330 may be a piece of polycarbonate, an acrylic sheet, silicon dioxide, or other material suitable for impact resistant windows. In some embodiments, the shield member 330 is transparent. In other embodiments, the shield member 330 may be translucent. In some other embodiments, the shield member 330 may be opaque.

(21) In the embodiment illustrated in FIGS. 8A and 8B, the shield member 330 includes spaced apart horizontal anchoring holes 810 and spaced apart anchoring holes 820. When assembled, two conditions may secure the shield member 330 in place. First, the anchoring holes 810 and 820 are held by the screws 350 that are inserted therethrough. Second, the interior frame 340 and the exterior frame 320 may provide a clamping load depending on the stiffness and dimensions of the raised edges 650 and 750. For example, in some instances the raised edges 650 and 750 are sized such that the combined lengths of the raised edges 650 and 750 are less than the thickness of the shield member 330 such that when assembled, provide a clamping force to retain the shield member 330 in place.

(22) The assembly and installation of the frame assembly 102 onto the sectional door 100 is discussed hereinafter. After at least one panel opening 172 is formed in the planar surface 148 of the applicable door section 110, 112, and/or 114 the frame assembly can be installed onto the applicable door section 110, 112 and/or 114. Prior to installation, the extension 620 of the exterior frame 320 is inserted into the corresponding slot 522 of the frame 310. The exterior frame 320 is then installed, approaching from the front or outer side of the sectional door panel 110, 112, and/or 114, into the opening 172.

(23) The shield member 330 is then placed in and/or is otherwise positioned adjacent the exterior frame 320, as best illustrated in FIG. 4. The interior frame 340 is then positioned to enclose and otherwise sandwich the shield member 330 with the exterior frame 320. Using a plurality of fasteners 350, the interior frame 340 is tightened against the exterior frame 320 to secure the frame assembly 102 to the applicable sectional door panel 110, 112, or 114. In particular, as the fasteners 350 are tightened, the bottom surface 640 of the exterior frame 320 is pulled into engagement with the planar portion 148 and the interior frame 340 is pulled into engagement with the shield member and the planar portion 148 via the arm member 752 so secure the shield member 330 inside the opening 172.

(24) In some embodiments, sealing members such as, for example, seals 512 and 514 as illustrated in FIG. 5, are be used to seal the frame assembly 102. According to the embodiment illustrated in FIG. 5, the first sealing member 512 is disposed in the groove 536 near or otherwise adjacent the first end 518 and the second sealing member 514 is disposed in the groove 522 near the second end 520. In use, the seals 512 and 514 prevent debris and other contaminants from entering or otherwise lodging between the frame 310 and the planar portion of the door 148 and the shield member 330. As such, tightening the interior frame 340 to the exterior frame 320 would cause the sealing members 512 and 514 in the frame 310 to seal against the shield member 330 and the planar surface 148, effectively protecting the assembly from rain, dust, and other contaminants from entering the assembly.

(25) According to some embodiments, the first sealing member 512 and the second sealing member 514 are formed of a rubber or other polymeric material deformable to conform and seal against abutting surfaces, such as for example, the gap between the decorative frame 310 and the planar portion 148 of the sectional door 110 and the decorative frame 310 and the shield member 330. In some embodiments, the first sealing member 512 and the second sealing member 514 are formed as part of the frame 310. For example, the frame 310 may be injection molded using two or more materials of different stiffness to enable a portion of the frame 310 to sealingly engage and otherwise contact the planar surface 148 and the shield member 330.

(26) Yet in other embodiments, the lengths of raised edges 650 and 750 provide a distance greater than the thickness of the shield member 330, thus the shield member 330 is solely secured by the anchoring holes 810 and 820 when loaded. Specific configuration for securing the shield member 330 depends on its material property. For example, thermal expansion, ductility or brittleness, or tendency to crack, and other considerations may impact the particular configuration to be used to secure the shield member 330 in place.

(27) FIG. 9 is a front view of the frame assembly 102 of FIG. 3. In the embodiment illustrated in FIG. 9, the shield member 330 includes louvers 910. FIG. 10 is a local cross sectional view of the frame assembly of the configuration of FIG. 9. Referring to both FIGS. 9 and 10, the louvers 910 allow the passage of light and air while preventing the passage of rain therethrough. In the embodiment illustrated in FIG. 9, the louvers 910 are fixed. However, in other embodiments, the louvers 910 may have difference sizes relative to the shield member 330 and may be made adjustable. In one example, the shield member 330 with the louvers 910 is transparent such that the louvers 910 prevent only rain and dust from entering. In another example, the shield member 330 with the louvers 910 is opaque such that direct light and rain are shielded away. In such instance, the shield member 330 may be made of metal for strength and durability. In some embodiments, tightening the interior frame 340 toward the exterior frame 320 would reaching a dimension limit defined by the raised edges 650 and 750 that stops the interior frame 340 from further pressing the shield element 330 toward the exterior frame 320.
