## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims benefit of U.S. Provisional Patent Application No. 62/085,918, filed on Dec. 1, 2014, and incorporates by reference the disclosure thereof in its entirety.


BACKGROUND OF THE DISCLOSURE
Recreational vehicle, buses, and the like, often include compartments accessible from outside the vehicle. The compartments may be used to store baggage or enclose vehicle equipment, for example, outdoor kitchens, outdoor televisions, and other mechanical and electrical equipment. A door typically is provided to secure the compartment's contents and to provide protection from the elements. The door typically is top-hinged. The door typically is provided with a form of seal to preclude the intrusion of moisture and other contaminants when the door is closed. As a practical matter, however, moisture often finds its way into the compartment when the door is opened. For example, if a top-hinged door is opened while it is raining, rain water flowing down the side of the vehicle may find its way past the hinge assembly and onto the inner surface of the door. When the door is then closed, the water may flow down the inner surface of the door and may collect on the compartment floor. This phenomenon cannot readily be precluded with a seal because the seal necessarily is broken when the door is open.
SUMMARY OF THE DISCLOSURE
The disclosure shows and describes one or more illustrative embodiments of a compartment door system configured to manage water intrusion.

DETAILED DESCRIPTION OF THE DRAWINGS
The drawings show an illustrative embodiment of a door system 100 structured to mitigate water intrusion. The system 100 includes a door frame 102, a door panel 104, a hinge 108 pivotally connecting the door panel to the door frame and one or more latches 106 for selectively securing the door panel to the door frame when the door panel is in the closed position.
As shown, the door frame 102 includes a continuous, generally rectangular, peripheral web 110 having a bottom (or first) side, a top (or second) side, a left (or third) side, and a right (or fourth) side (sometimes referred to, respectively, as header, sill, and right and left jamb portions of the door frame) cooperating to define an opening 109 there through. In other embodiments, the door frame and web could have other shapes, including non-rectangular shapes. The web 110 has an outer or outboard (or first) end and an inner or inboard (or second) end. The web 110 is dimensioned to fit into a correspondingly-shaped opening in a side wall of a structure (not shown), for example, the side wall of a recreational vehicle or bus. Any or all of the bottom, top, left, and right sides of the web 110 may define one or more apertures 124 configured to receive fasteners that may be used to secure the door frame 102 to the side wall of the structure.
An outer (or first) flange 112 extends outwardly (away from the opening 109) from the web 110 proximate the outer end thereof. The outer flange 112 is generally perpendicular to the web 110. The outer flange 112 is configured to engage the outer surface of the sidewall of the structure when the door frame 102 is connected thereto. A seal (not shown) may be provided between the outer flange 112 and the sidewall. A lip 122 extends outwardly from the web 110 proximate an inner end thereof. The lip 122 may engage the inner surface of the sidewall of the structure when the door frame 102 is connected thereto.
A seal (or second) flange 114 extends inwardly (toward the opening 109) from an intermediate portion of the web 110 between the outer and inner ends thereof. The seal flange 114 is generally perpendicular to the web 110. The seal flange 114 is shown as a continuous peripheral flange extending about the entirety of the interior surface of the web 110. The portion of the seal flange 114 extending from the bottom portion of the web defines one or more perforations 126 there through. The perforations 126 may abut the interface between the seal flange 114 and the web 110, or they could be distanced therefrom. The upper, left side, and right side portions of the seal flange 114 are shown as imperforate, but any or all of them could define one or more perforations similar to perforations 126 there through.
In an embodiment, the seal flange 114 could be discontinuous. For example, the portion of the seal flange extending from the bottom side of the web could include one or more discontinuities configured to allow passage of water there through. In such an embodiment, the perforations 126 could be omitted.
A guard (or third) flange 116 extends inwardly from an intermediate portion of the web 110, inboard of the seal flange 114. That is, the guard flange extends from an intermediate portion of the web 110 between the seal flange 114 and the inner end of the web. The guard flange 116 also is generally perpendicular to the web 110 such that the guard flange and the seal flange 114 are generally parallel to each other. The seal flange 114 and the guard flange 116 cooperate to form a channel or trough 144 there between. The seal flange 114 is shown as being longer (extending further inwardly) than the guard flange 116. In other embodiments, the seal flange 114 and the guard flange 116 could be the same length, or the guard flange could be longer than the seal flange.
The guard flange 116 also is shown as an imperforate, continuous, peripheral flange extending about the entirety of the interior surface of the web 110. In an embodiment, the guard flange could be discontinuous and/or define one or more perforations (not shown) there through. Any discontinuity or perforation in the portion of the guard flange 116 extending from the bottom side of the web 110 preferably would be covered or filled with a material suitable to preclude fluid communication through such discontinuity or perforation.
A seal 120 is attached to the seal flange 114 with a sealing surface facing outwardly, toward the outer end of the web. The seal 120 may comprise, for example, a U-shaped mounting portion 130 configured to receive the seal flange 114 within the “U” thereof, and a bulb seal portion 132 on the outboard side of the mounting portion. The seal 120 may be compressed between the door panel 104 and the seal flange 114 when the door panel is in the closed position.
The hinge 108 includes a first leaf 134 attached to an inner surface of an upper portion of the web 110, outboard of the seal flange 114. The hinge 108 also includes a second leaf 136 attached to the door panel 104. The hinge 108 further includes a hinge pin 138 pivotally connecting the first leaf 134 and the second leaf 136. The hinge pin 138 may be integral with one of the first leaf 134 and the second leaf 136, or the hinge pin may be a discrete structure.
The door panel 104 is shown as comprising a core 140 disposed within a peripheral door panel frame 142. The door panel 104 could be configured in other ways as well. The door panel 104 is pivotally connected to the door frame 102 via hinge 108, as discussed above. So connected, an outer surface of the door panel 104 may be generally flush with the outer flange 112 of the door frame 102 when the door panel is in a closed position. Also, an inner surface of the door panel 104 may engage with the seal 120 when the door panel is in the closed position. As such, the door panel 104, when in the closed position, may be substantially contained within the door frame 102. The door panel 104 may define one or more sites 148 for receiving the latch(es) 106. The sites 148 may comprise apertures extending through the door panel 104, for example, through the core 140 of the door panel. Alternatively, the sites 148 may define locations on the door panel 104 where the latch(es) 106 may be surface-mounted thereto.
The door frame 102 may be fabricated as an extrusion. The extrusion may be bent to form a desired frame size and shape. In the illustrated embodiment, the ends of the door frame extrusion are spliced together at about the midpoint of the top portion of the frame. The free ends of the door frame extrusion abutting the splice may be maintained in position solely by attachment of the first hinge leaf to the upper portion of the frame. Alternatively, the free ends of the door frame extrusion abutting the splice could be welded, bonded, or otherwise joined together, for example, by mechanical means.
The door panel frame 142 also may be fabricated as an extrusion. The extrusion may be bent to form a desired frame size and shape. The size and shape typically would be complementary to the size and shape of the door panel core 140 and the door frame 102. In the illustrated embodiment, the ends of the door panel frame extrusion are spliced together at about the midpoint of the bottom portion of the door panel frame 142. The free ends of the door panel frame 142 abutting the splice may be, but need not be, welded, bonded, or otherwise joined together, for example, by mechanical means. In the illustrated embodiment, the side of the door panel frame 142 abutting the bottom of the door frame 102 defines weep holes in the form of perforations 146 there through.
In use, the door panel 104 may be opened to allow access to the compartment it covers. When the door panel 104 is in an open (or second) position, water running down the outer surface of the wall in which the door system 100 is installed may find its way, whether through surface tension, splashing or another modality, to the inner surface of the door panel 104. When the door panel 104 is closed, this water may flow or otherwise migrate to the bottom of the inner surface of the door panel and then into the channel 144 defined by the seal flange 114 and the guard flange 116. The seal flange 114 and the guard flange 116 are arranged to preclude or mitigate migration of the water to the inboard side of the guard flange. The water then may exit the channel 144 through the perforations 126 in the seal flange 114 to the outboard side of the door frame 102. With the door panel 104 in the closed position, a gap 103 exists between the outer perimeter of the door panel 104 and the inner perimeter of the door frame 102 (that is, the inner surface of the web 110), so that the water may flow out of the door frame to the environment. In this manner, the system 100 may mitigate the effects of water intrusion into the door assembly 100.
The sill or bottom portion of the web 110 (or a portion thereof) could be angled or flared downwardly to the outboard side thereof so that the water exiting the perforations 126 may have a downhill path toward the outer edge of the web and the door frame 102 generally to preclude or mitigate water from ponding on the web or in the channel 144.
References to direction and orientation herein are to be construed in a relative, and not necessarily absolute, sense.
The embodiments shown and described herein are illustrative and may be modified without departure from the scope of the appended claims.
