DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

For the purposes of promoting an understanding of the principles of the invention, reference will now be made to a number of illustrative embodiments shown in the attached drawings and specific language will be used to describe the same.

Referring now to FIG. 1, a perspective assembly view is shown of installation of one illustrative embodiment of a pair of skylights 18A and 18B and a sidewall 12 of a trailer 14. In the illustrated embodiment, a pair of openings 16A and 16B have been formed in the sidewall 12 of the trailer 14. The openings 16A and 16B are spaced apart relative to each other, and both are positioned approximately the same distance below a top rail 18 of the trailer 14.

The skylights 18A and 18B each include a frame 20A and 20B respectively, and a window 22A and 22B, respectively. The windows 22A and 22B are generally light transmissive, and may be, for example, transparent or translucent. In the illustrated embodiment, each of the frames 20A and 20B define an opening 30 therethrough that is sized slightly smaller than the windows 22A and 22B, and the windows 22A and 22B are configured to be mounted to the frames 20A and 20B, respectively, such that light may pass through the openings 30 defined through the frames 20A and 20B. Each of the frames 20A and 20B further define a flange 34 that extends laterally from, and radially about, the opening 30, and each flange 34 defines an outer flange surface 34B.

In one illustrative embodiment, the openings 16A and 16B are positioned approximately four inches on center from the top rail 18 of the trailer 14, and are spaced apart from each other by approximately 5.5 inches on center. In this embodiment, each of the frames 20A and 20B are sized to have a four inch inner diameter and a five inch outer diameter. The windows 22A and 22B in this embodiment are illustratively 0.062 inch thick, clear, LEXAN® polycarbonate resin thermoplastic, and may be mounted to the frames 20A and 20B, respectively, via any conventional mounting technique, e.g., adhesive or other bonding medium. It will be understood that the foregoing dimensional information is provided only by way of example, and that other dimensions of the skylights 18A and 18B and/or positioning of the skylights 18A and 18B relative to the sidewall 12 of the trailer 14 and/or to each other may alternatively be used. It will further be understood that while two skylights 18A and 18B are illustrated in FIG. 1 as being mounted to the vehicle wall 12, this disclosure contemplates embodiments in which more or fewer skylights are mounted to the vehicle wall 12 at any location, and embodiments in which two or more skylights are mounted to the vehicle wall 12 with any orientation relative to each other and/or with any orientation relative to the vehicle 12 and/or any component thereof. Moreover, it will be understood that light transmissive or translucent material other than LEXAN® may be used to form the windows 22A and 22B. Finally, although the openings 16A and 16B, frames 20A and 20B, and windows 22A and 22B are illustrated in FIG. 1 as being circular and/or annular in shape, this disclosure contemplates other embodiments in which the periphery of the openings 16A, 16B, frames, 20A, 20B and/or windows 22A, 22B have shapes other than circular or annular.

Referring now to FIG. 2, a perspective view is shown of one of the frames, designated generally at 20, of the skylight 18A, 18B illustrated in FIG. 1. In the illustrated embodiment, the frame 20 defines an inner frame periphery 32 that extends radially about the opening 30, and therefore extends radially about the window 22A, 22B (not shown in FIG. 2). The flange member 34 extends laterally away from, and radially about, the opening 30 defined through the frame 20, and the flange member 34 defines an inner flange surface 34A opposite to the outer flange surface 34B (see FIG. 1). The inner flange surface 34A and the outer flange surface 34B merge together and terminate at an outer flange periphery 36.

The frame 20 further defines a wall member 38 that extends downwardly away from the frame 20 adjacent to, and about, the inner periphery 32, of the frame 20. In the embodiment illustrated in FIG. 2, the wall member 38 is made up of a number, e.g., four, of wall segments 39, and a gripping arm 50 extends away from the frame 20, adjacent to the inner periphery 32, between each adjacent wall segment 39.

Referring now to FIG. 3, a magnified portion “A” of the frame 20 of FIG. 2 is shown. In this magnified view, two adjacent wall sections 39 of the wall member 38 are shown terminating at ends 38A and 38B, respectively, to form a gap 40 therebetween. In this embodiment, the illustrated one of the gripping arms 50 is positioned within the gap 40 and extends outwardly away from the frame 20 adjacent to the inner periphery 32. Each of the gripping arms 50 terminates at a wall-engaging member 52 that generally extends beyond an outer edge 38C of the wall member 38. As illustrated in FIG. 3, for example, the wall-engaging member 52 defines a gripping tooth having a wall-engaging surface 54 that is oriented away from the inner periphery 32 generally in the same direction as the flange member 34. As will be described in greater detail hereinafter, the wall-engaging surface 54 of the wall-engaging member 52 is configured to engage an inner surface of the vehicle sidewall 12 adjacent to the opening 16A, 16B when the skylight 18A, 18B is inserted into the opening 16A, 16B formed in the wall 12 of the vehicle 14, or to engage the wall 12 of the vehicle 14 within the opening 16A, 16b when the skylight 18A, 18B is inserted into the opening 16A, 16B, depending upon the thickness of the wall 12 of the vehicle 14 relative to the lengths of the gripping arms 50. As shown in FIG. 4, which is a magnified view of the portion “B” identified in FIG. 2, each of the gripping arms 50 further defines a notch 56 therein adjacent to the frame 20. The notch 56 is configured to facilitate breaking of the gripping arm 50 away from the frame 20 after installation of the skylight 18A, 18B in the wall 12 of the vehicle 14.

Referring again to FIG. 2, the gripping arms 50, and thus the gaps 40, are illustrated as being substantially equally spaced about and adjacent to the inner periphery 32 of the frame 20. Alternatively, the plurality of gripping arms 50 and gaps 40 need not be equally spaced about the inner periphery 32 of the frame 20. Moreover, while four such gripping arms 50 and, corresponding gaps 40, are shown in the illustrated embodiment, it will be understood that more or fewer such gaps 40 and gripping arms 50 may be provided. In an alternative embodiment, the wall member 38 may be a continuous wall member, i.e., with no gaps 40, that extends away from the frame 20 adjacent to, and entirely about, the inner periphery 32 of the frame 20. In such embodiments, the gripping arms 50 may extend from the outer edge 38C of the wall member 38. In either case, the gripping members 52 extend beyond the outer edge 38C of the wall member 38.

Referring now to FIG. 5, an elevational view of another illustrative embodiment of a skylight 18′ is shown mounted to a wall 12, e.g., a sidewall, of a vehicle, e.g., a trailer. The skylight 18′ is identical to the skylight 18 illustrated and described herein, with the exception that the window 22′ is, in the skylight 18′, integral with the frame 20 such that the frame 20 and the window 22′ are of unitary construction. In this embodiment, the entire skylight 18′ may illustratively be formed of LEXAN® polycarbonate resin thermoplastic in accordance with a conventional molding process, although this disclosure contemplates embodiments in which the skylight 18′ is formed of one or more other conventional materials. As illustrated in FIG. 5, the wall member 38 and gripping arms 50 of the skylight 18′ extend into the opening 16 that is formed in the wall 12 of the vehicle 14 when the skylight 18′ is mounted to the wall 12. As also illustrated in FIG. 5, at least a portion of the inside surface 34A of the flange member 34 contacts an outer surface 12A of the wall 12 when the skylight 18′ is mounted to the wall 12.

Referring now to FIG. 6, a cross-sectional view of the skylight 18′ and vehicle wall 12 of FIG. 5 is shown as viewed through the section line 6-6. As shown in FIG. 6, the gripping arms 50 are configured such that the wall-engaging or gripping surfaces 54 of the wall-engaging or gripping members 52 engage the inner surface 12B of the vehicle side wall 12 when the skylight 18′ is mounted to the vehicle wall 12. Alternatively, in embodiments in which the thickness of the vehicle wall 12 between the outer surface 12A and the inner surface 12B thereof is greater than the lengths of the gripping arms 50 relative to the frame 20, the gripping arms 50 are configured to yield inwardly toward each other, i.e., radially away from the frame member 38, such that the gripping surfaces 54 engage the vehicle wall 12 within the opening 16. In either case, a bonding medium 60 is disposed between the inner surface 34A of the flange member 34 and the outer surface 12A of the vehicle wall 12, and the gripping arms 50 act to maintain the flange member 34 in contact with the outer surface 12A of the vehicle wall 12 while the bonding medium 60 sets or cures or otherwise bonds the flange 34 to the outer surface 12A of the vehicle wall 12. Thereafter, the gripping arms 50 may be manually broken away from the skylight 18′ by repeatedly moving the gripping arms 50 relative to the frame 20 until the gripping arms 50 break away at the notches 56.

Referring now to FIG. 7, a flowchart is shown of one illustrative embodiment of a process 70 for installing either the skylight embodiments 18 or 18′ in a wall 12 of a vehicle 14. While the vehicle wall 12 has been illustrated in FIG. 1 as comprising a side wall of a conventional trailer, it will be understood that the wall 12 may alternatively be a side wall, floor, ceiling or other wall of other conventional towed or towing vehicles. In any case, the process 70 begins at step 72 where a skylight 18 or 18′ is provided, and has at least a frame 20 defining an inner periphery 32 about a window 22, 22′, and having a flange 34 extending away from the inner periphery 32 of the frame 20, and a plurality of gripping arms 50 extending away from the inner periphery 32 of the frame 20. Thereafter at step 74, an opening 16 is formed through a wall 12 of a vehicle, and the opening 16 is sized to be at least slightly larger than the inner periphery 32 of the frame 20. By forming the opening 16 in this manner, the wall member 38 and gripping arms 50 can extend into the opening 16 when the skylight 18, 18′ is mounted to the wall 12 of the vehicle.

Following step 74, a bonding medium is applied at step 76 to the inner surface 34A of the flange member 34. Illustratively, the bonding medium 60 is applied to the inner surface 34A of the flange member 30 entirely about the inner periphery 32 of the frame 20 so that no gaps will exist in the bonding medium 60 about the periphery 32 of the frame 20. Alternatively, the bonding medium 60 may be applied to the outer surface 12A of the wall 12, e.g., about the periphery of the opening 16, or to both of the inner surface 34A of the flange member 34 and the outer surface 12A of the wall 12. In one embodiment, the bonding medium 60 may be an adhesive tape, e.g., a high-bond, double-sided formable gasket tape. Alternatively, the bonding medium 60 may be provided in the form of a medium that if configured to set or cure after the skylight 18, 18′ is mounted to the side 12 of the vehicle as just described, thereby forming an air-tight and water-tight bond between at least a portion of the inner surface 34A of the flange member 34 and the outer surface 12A of the wall 12 of the vehicle about the inner periphery 32 of the skylight 18, 18′. Illustratively, the formable medium may be or include a durable adhesive or a durable sealant or the like. In one illustrative embodiment, for example, the bonding medium 60 may be LORD® 7556 equal-mix, two-component, clear urethane adhesive, although this disclosure contemplates alternatively using other conventional adhesives, sealants or the like.

From step 76, the process 70 advances to step 78 where the gripping arms 50 of the skylight 18, 18′ are inserted into the opening 16 through the wall 12 of the vehicle such that the bonding medium 60 contacts the flange member 34 and the outer surface 12A of the vehicle wall 12 about the opening 16 while the gripping arms 50 engage the vehicle wall 12, e.g., the inner surface 12B of the vehicle wall 12 adjacent to the opening 16 as illustrated in FIGS. 5 and 6, or the vehicle wall 12 within the opening 16 when the thickness of the vehicle wall 12 between the outer surface 12A and inner surface 12B thereof is greater than the lengths of the gripping arms 50 relative to the frame 20. With the gripping arms 50 engaging the vehicle wall 12 as just described, the skylight 18, 18′ is thereby held in place while the bonding medium 60 cures or sets. Following step 78, an optional step 80 may be formed in which the gripping arms 50 are broken away from the inner periphery 32 of the frame 20 of the skylight 18, 18′ after the bonding medium 60 cures or sets.

While the invention has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as illustrative and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
