This disclosure relates generally to covers for drains. In particular, a cover for a roof drain is disclosed that includes features to prevent and/or reduce the blockage of roof drains by solid debris.
A variety of drains exist for removing unwanted fluids, such as rainwater or melted snow. Some drains are intended for the roof in order to drain such fluids from the tops of buildings or other structures. Because roof drains are typically exposed to the elements, they are susceptible to damage or clogging from a variety of sources. Also, due to their isolation, any damage or tampering with such drains may go unnoticed until a problem occurs with the functioning of the drain. Further, harmful elements may damage or clog the drains, such as hail or strong winds and solid debris carried by such elements. Other drains besides those intended for the roof may also be susceptible to similar problems. For example, street drains may be susceptible to clogging from collected street debris or to damage by passersby. Therefore, drains in many contexts may be exposed to danger.
Because of these and other concerns, some drains may be fitted with a cover. The cover may protect the drain from such harmful influences. However, typical drain covers have many drawbacks. They typically must be fastened to the drains and thus must be compatible with the geometry or corresponding structure of the particular drain type being covered. This limits the number of types of drains that may be fitted with the covers. In addition, conventional drain covers easily clog and prevent the passage of fluid, due to leaves or other debris building up along the outside of the covers. Typical drain covers receive fluids through spaces defined by vertically-oriented members and have gravel guards near the base of the covers to prevent gravel and other small solid debris from flowing into the cover. If leaves or other debris block these members and the spaces in between, then water is prevented from flowing through the cover and entering the drain. Further, the gravel guard on typical covers severely impede the flow of fluids into the cover as well.
There is therefore a need for improved drain covers that overcome the aforementioned drawbacks.
Features are disclosed for a drain cover. The cover may be used with roof drains, but it is not limited to use with only roof drains. The cover may be used with floor drains, indoor or outdoor drains, street grating, and other drains. The cover may be installed and removed over these and other drains easily and quickly. The drain allows for fluid flow while preventing and/or reducing blockage. The cover may prevent and/or reduce buildup of flow-impeding debris on and along the outside of the drain and the cover, and the cover may allow passage of fluid through the cover and into the drain even when there is a buildup of debris on or around the cover. The cover may have an advantageously-designed body including an extended outer flow ring, or “skirt,” that contributes to the improved fluid collection capability.

The skirt may comprise a center region having a flat portion and curved portions surrounding the flat portion. The cover may have an overall height H as measured axially from a lower surface of the skirt to an upper edge of the dome, where the outer edge has a portion located a perpendicular distance R2 from the vertical axis, and wherein the distance R2 is greater than H. The distance R2 may be at least 1.5 times greater than H.
This summary is meant to provide an introduction to the concepts that are disclosed within the specification without being an exhaustive list of the many teachings and variations upon those teachings that are provided in the extended discussion within this disclosure. Thus, the contents of this summary should not be used to limit the scope of the claims that follow. All of these embodiments are intended to be within the scope of the present disclosure. These and other embodiments will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiments having reference to the attached figures, the invention not being limited to any particular preferred embodiment(s) disclosed or summary provided herein.
Elements in the figures have not necessarily been drawn to scale in order to enhance their clarity and improve understanding of these various elements and embodiments described herein. Furthermore, elements that are known to be common and well understood to those in the industry are not depicted in order to provide a clear view of the various embodiments described herein, thus the drawings are generalized in form in the interest of clarity and conciseness.
In the following discussion that addresses a number of embodiments and applications, reference is made to the accompanying drawings that form a part hereof, and in which is shown by way of illustration specific embodiments in which the embodiments described herein may be practiced. It is to be understood that other embodiments may be utilized and changes may be made without departing from the scope of the disclosure.
Various inventive features are described below that can each be used independently of one another or in combination with another feature or features. However, any single inventive feature may not address all of the problems discussed above or only address one of the problems discussed above. Further, one or more of the problems discussed above may not be fully addressed by the features of each embodiment described below.
In certain embodiments, the cover disclosed herein prevents or reduces the blockage of fluid from entering a drain caused by the buildup of leaves and other debris. Therefore, even with buildup of debris along or on the outside of the cover, the cover still allows for the passage of fluid through the cover and into the drain. For instance, debris may collect on top of the cover and the cover may still allow for the drainage of fluid even with such debris on the cover. Further, the features of the cover mitigate the chances of such buildup in the first place. The cover can be used with new drains or retro-fitted for existing drains.
The cover can have a top portion configured to be positioned generally over the drain, a middle portion that may be slightly angled off the vertical and extending outward from the top portion, and a lower flange or portion that is generally horizontal but slightly sloped downward and extending outward from the middle portion. This lower portion may have a large area over which fluid and debris can flow, in order to reduce the chances of debris buildup and to optimize the flow of fluid through spaces or openings in the lower portion. The middle and lower portions may have radially-elongated spaces defined by ribs. Theses spaces may extend through the middle and lower portions and thereby allow fluids to flow through these two portions. The top portion may have spaces as well. The cover can also have an outer ring that attaches to the outer perimeter of the lower portion.
Further, the cover may have a mount configured to attach to a surface or surfaces other than the drain itself. The mount may be installed around the drain, and the cover may be easily attached to the mount. The mount may have flex joints that allow for the mount to conform to elevations or other protuberances on the mounting structure or surface to which the mount attaches. The cover may attach to the mount by friction fit, for instance by snapping projections of the cover into corresponding receiving structures of the mount. This configuration of the various portions of the drain cover, along with other features of the drain cover disclosed herein, produces a cover with improved performance characteristics, including allowing fluids to flow through the cover and into the drain even in the presence of buildup of solids or other foreign debris along and/or on the outside of the cover while also reducing the amount of debris buildup around the drain and cover. In certain embodiments, the cover can be coupled to a mount that is coupled to the drain. The cover may attach to the mount by friction fit, for instance by snapping projections of the cover into corresponding receiving structures of the mount.
As shown in
The body 110 may include one or more sections coupled together, such as an upper dome section or dome 126 coupled with a lower skirt section or a skirt 120. As shown, the body 110 may include the skirt 120. The skirt 120 may be a relatively lower part or parts of the cover 100. By “lower” it is understood that this description is relative to the orientation shown in
The skirt 120 may comprise a part or parts that are oriented generally in the manner of a flange or other arcuate configuration. By “arcuate” it is meant that a feature may be rounded in a variety of ways, roughly similar to an arc. Therefore, the term “arcuate” may refer to a circular shape. However, arcuate may also refer to other rounded shapes, such as elliptical, circumferential, annular, other forms of rounded, or combinations thereof. Arcuate does not impose any requirements on the shape of the edges of the arcuate part. Thus, arcuate may also refer to a rounded shape having straight ends or edges, such as a 2D cross-section extruded about an axis to forma 3D part, but where the resulting 3D part has straight outer edges such that the planform (i.e. view from top of bottom of the part) of the 3D part appears to be square- or rectangular-shaped. Therefore, the term arcuate is not meant to be limiting the configuration of the various parts to any one particular shape.
Various features of the cover 100 may be described with reference to the central axis 10, as shown. The axis 10 may be a geometric reference line that is not a physical feature of the cover 100. In some embodiments, the axis 10 may be defined by one or more parts of the cover 100. In some embodiments, various features of the cover 100 may be circular with the axis 10 intersecting the center or near the center of the various circular portions. However, the various features of the cover 100 need not be circular but may still be referred with reference to the axis 10. The axis 10 may be vertically-oriented as shown.
The skirt 120 may be coupled with a lower portion 121 of the upper dome 126. The lower portion 121 may be a generally arcuate section of the cover 100 that extends in a swept out path about the axis 10. The lower portion 121 may provide an interface or juncture with which various portions of the cover 100 may connect. In some embodiments, the lower portion 121 may merely be the end of various intersecting or interconnecting portions of the cover 100. The lower portion 121 may have a variety of different shapes of cross-sections that are extruded in a generally arcuate manner about the axis 10. Theses shapes may be square, rectangular, circular, rounded, polygonal, other shapes, or combinations thereof.
The lower portion 121 may be located approximately a perpendicular distance R1 from the axis 10. R1 may be a dimension equal to roughly half of the total width of the lower portion 121. The distance R1 may be a radius of a circular lower portion 121. However, the lower portion 121 may not be circular, and thus in some embodiments the distance R1 may not be a radius. R1 may be measured perpendicularly from the axis 10 to any region of the lower portion 121, including to regions of the lower portion 121 that are relatively closer are farther from the axis 10 than other regions of the lower portion 121. Further, R1 need not be constant as measured at different angular locations of the cover 100. For example, the lower portion 121 may be arcuate but with straight outer edges such that the dome 126 appears square or rectangular as viewed from the top. For such a shape, R1 would vary depending on which angular location the dimension is measured (i.e. which cross-section or side view is used). Thus, R1 may vary with such a configuration as measured at different angular locations. In some embodiments, R1 refers to a maximum or minimum width of the dome 126. For a non-circular dome 126, R1 may be a maximum or minimum width, for example the maximum or minimum perpendicular distance from the axis 10 to respectively a closest portion or farthest-most portion of the dome 126.
The skirt 120 may flare outward and downward from the lower portion 121 to an outer edge 129 (see
The skirt 120 may include one or more lower ribs 122. The lower ribs 122 may be connected to our otherwise coupled with the lower portion 121. The lower ribs 122 may be elongated members coupled with the lower portion 121 and extending outward therefrom. The lower ribs 122 may couple with the lower portion 121 and extend radially outward therefrom. There may be multiple lower ribs 122. There may be 48 lower ribs 122 (only some are visible in
The lower ribs 122 may extend from the lower portion 121 to an outer perimeter 125. The outer perimeter 125 may be a portion or portions of the cover body 110, such as the skirt 120, extending along the outside of the cover body 110. The outer perimeter 125 is visible in
The cover 100 may include one or more openings or lower spaces 124. The body 110 may include the one or more lower spaces 124. As shown, the skirt 120 may at least partially define or form the one or more lower spaces 124. The lower spaces 124 may be openings extending through various portions of the cover 100 to allow fluid flow therethrough. As shown, the lower spaces 124 may be openings extending through the skirt 120 to allow fluid flow through the skirt 120. The lower spaces 124 may be defined by various portions of the cover 100. As shown, the lower spaces 124 may be defined by features of the skirt 120, such as the lower ribs 122, the lower portion 121, and/or the outer perimeter 125. For example, the lower spaces 124 may be defined on two sides by two adjacent lower ribs 122, on one end buy a portion of the lower portion 121, and on the opposite end by a portion of the outer perimeter 125. In this manner, the lower spaces 124 may be openings defined or otherwise formed by various physical features of the skirt 120. The lower spaces 124 may be completely open as shown. In some embodiments, the lower spaces 124 may have other features therein, such as screens, filters, or other features that may affect the flow of fluid therethrough. For instance, screens in the lower spaces 124 may facilitate allowing the passage of fluid flow while blocking the passage of larger or solid debris, such as leaves and sticks.
The dome 129 may include an arcuate sidewall 130. The sidewall 130 may be located generally above the skirt 120 as oriented in
The sidewall 130 may include one or more upper ribs 132. As shown, the upper ribs 132 may be elongated members extending along the sidewall 130. The upper ribs 132 may be elongated with a generally rectangular or square cross-section. However, the upper ribs 132 may have a variety of other shaped cross-sections, such as those described with respect to the lower ribs 122, or other shapes. The upper ribs 132 may be oriented in an arcuate manner generally about the central vertical axis 10. In some embodiments, the upper ribs 132 are arranged in a circular shape about the axis 10. However, other arrangements of the upper ribs 132, such as elliptical, oval, or other shapes, may be implemented.
The sidewall 130 may be include a lower portion 121. In some embodiments, the sidewall 130 may be formed from the same monolithic piece of material as the lower portion 121. In some embodiments, the sidewall 130 and the skirt 120 are formed from the same monolithic piece of material. However, the sidewall 130 may also be coupled with the lower portion 121 and/or the skirt 120 in a variety of ways, such as with mechanical attachments, adhering, fastening, bonding, or other suitable means.
The sidewall 130 may include any number of the upper ribs 132. There may be fourteen of the upper ribs 132 (only some are visible in
The upper ribs 132 may be connected on one end to the lower portion 121 and on the opposite end to various other features of the cover 100. As shown, one end of the upper ribs 132 may be connected or otherwise coupled with an upper perimeter 133. The upper perimeter 133 may be a portion or segment of the sidewall 130 that extends in an arcuate manner about the central axis 10. The upper ribs 132 may be coupled with the upper perimeter 133 in a variety of manners. As shown, the upper perimeter 133 and the upper ribs 132 may be formed from the same monolithic piece of material. In some embodiments, the upper perimeter 133 may be a separate part that is subsequently attached to or otherwise coupled with the upper ribs 132 in a variety of suitable means, such as bonding, fastening, adhering, other mechanical means, other suitable means, or combinations thereof.
As mentioned, the cover 100 may include one or more upper spaces 134. that provide openings through the cover 100 through which fluid may flow. As shown, the upper spaces 134 may be formed by various features of the body 110. The upper spaces 134 may be formed by various features of the sidewall 130. For instance, as shown the upper ribs 132 may partially form the upper spaces 134 on two or more sides of the upper spaces 134. The upper spaces 134 may also be defined on one or more sides by the upper perimeter 133. As shown, the upper perimeter 133 or a portion thereof may form an upper side of the upper spaces 134 as oriented, and/or the opposite side of the upper spaces 134 may be defined by a portion of the lower portion 121. Therefore, the upper spaces 134 may be defined by various surfaces of adjacent upper ribs 132, adjacent portions of the upper perimeter 133, and adjacent portions of the lower portion 121. As shown, the upper spaces 134 may have a generally rectangular shape. The upper spaces 134 may therefore have the appearance of a window. However, the upper spaces 134 may have a variety of shapes, such as square, rounded, segmented, other shapes, and/or combinations thereof. In some embodiments, the upper space is 134 may have the same or similar shapes as the lower spaces 124. Further, the upper spaces 134 may be entirely open with no physical objects therein. However, the upper spaces 134 may also be partially or entirely filled with a screen, filter, or the like to allow the flow of fluid therethrough while blocking the passage of debris such as solids. The upper spaces 134 may contribute to the effectiveness of the cover 100 by receiving fluid that might flow over the skirt 120 and/or over any debris or other blockages built up on the skirt 120. The upper spaces 134 may also be sized to receive some of the debris such the debris will either catch on the upper space 134 and not fall onto the drain or block the skirt 120, or the debris may fall through the upper space 134 and be received into the cavity 112 of the cover 100.
The cover 100 may include a cavity 112. The cavity 112 may be a space or spaces formed by various features of the cover 100. As shown, the body 110 may form the cavity 112 therein. For instance, the sidewall 130 may surround and define or form the cavity 112 therein. The cavity 112 may also be formed and or defined by other features of the cover 100. For example, the skirt 120 may also define a portion or portions of the cavity 112. In some embodiments, the cavity 112 may be a space with a volumetric shape that complements the underside of the body 110 of the cover 100. The cavity 112 may be a space defined or formed by the body 110 or other features of the cover 100 that facilitates the flow of fluid therethrough. For example, the cavity 112 may be a space in between various features of the cover 100 and the drain over which the cover 100 is positioned. The cavity 112 may be in fluid communication with the various spaces of the cover, such as the lower spaces 124 of the skirt 120 and/or the upper spaces 134 of the sidewall 130. Fluid may flow through these or other spaces and into the cavity 112 and then into the drain.
The dome 126 may include a top 140. The top 140 may be an uppermost portion or portions of the dome 126 as oriented in
The top 140 may also include the upper perimeter 133 or portions thereof. Therefore, the upper perimeter 133 may form a portion of the sidewall 130 as well as a portion of the top 140. Thus, the top 140 may have a generally arcuate shape such as those described above with respect to the sidewall 130 and the upper perimeter 133. In some embodiments, the upper perimeter 133 may extend entirely across the top 140 such that the top 140 forms a surface, which may be curved, flat or other shapes. As shown and described below, the top 140 may have other features and or separable components.
As shown, the top 140 may include a lid 141. The lid 141 may be a portion or portions of the top 140. The lid 141 may be generally centrally-located or it may be in other locations of the top 140. As shown, the lid 141 may have a generally arcuate shape, such as circular or other shape, that is complementary to the arcuate shape of the upper perimeter 133. The lid 141 may be removable. Removal of the lid 141 or other features from the cover 100 may facilitate with observing and/or accessing the cavity 112 and/or the drain thereunder. For instance, a user may remove the lid 141 in order to observe the drain and/or internal features of the cover 100. Also the ability to remove the lid 141 allows an anti-vortex plate or other devices to be installed. In some embodiments, the lid 141 may be a generally circular part of the upper portion of the top 140 which is removable therefrom. For example, the lid 141 may interface with the upper perimeter 133 at a generally circular boundary. The lid 141 may also interface with the upper perimeter 133 or other portions of the cover 100 in a variety of other manners, including with other suitable shapes and configurations of this and/or other interfaces.
The cover 100 may include one or more top ribs 142. The top ribs 142 may be generally elongated members located at or near the top 140. The top ribs 142 may have a variety of cross-sectional shapes, such as rectangular, or any of those described herein, for example with respect to the upper ribs 132 and/or the lower ribs 122. As shown, the top ribs 142 may be oriented generally parallel to each other. However, a variety of other arrangements may be implemented with the top ribs 142. As further shown, the top ribs 142 may have a variety of lengths. Some of the top ribs 142 may be longer or shorter than other top ribs 142. As shown, the top ribs 142 generally near the center of the top 140 may be longer than those top ribs 142 located generally farther from the center. As shown, there may be six top ribs 142. In some embodiments, there may be more or fewer top ribs, for example, none, one, two, three, four, five, seven, eight, nine, ten, fifteen, twenty, twenty-five, fifty, one hundred, or intermediate or greater numbers of top ribs 142. The top ribs 142 may be connected on one end to a first portion of the upper perimeter 133 and on the opposite end to an opposing portion of the upper perimeter 133. As shown, the top ribs 142 may be connected on one end to one portion of the lid 141 and on the opposite end to an opposing portion of the lid 141.
The cover 100 may include one or more top spaces 144. The top spaces 144 may be openings through the top 140 of the cover 100 that allow the passage of fluid therethrough. The top spaces 144 may prevent the passage of large solids therethrough such as large pieces of debris, large sticks, and the like. The top spaces 144 may be large enough to allow some debris to pass therethrough in order to prevent a large buildup on the skirt 120. As shown, the top spaces 144 may be formed by various features of the body 110, such as the top 140. For example, the top spaces 144 may be formed by one or more top ribs 142 and/or by one or more surfaces of the lid 141. In some embodiments, the top spaces 144 may be formed by one or more top ribs 142 and various surfaces of the upper perimeter 133. These are just some examples and the top spaces 144 may be defined in other ways, such as by combinations of the top ribs 142, the lid 141, and/or the upper perimeter 133. In some embodiments, some or all of the top spaces 144 may be defined on two opposing sides by two adjacent top ribs 142. In some embodiments, the ends of the top spaces 144 may be defined by two opposing sides or portions of the lid 141 or of the upper perimeter 133. Some of the top spaces 144 may be defined on one side by the top rib 142 and on the opposite side by a portion of the lid 141. In some embodiments, some of the top spaces 144 may be defined in part by a top rib 142 on one side and on the opposite side by a portion of the upper perimeter 133. The top spaces 144 may be entirely open therethrough, as shown. In some embodiments, the top spaces 144 may include screens or filters therein to facilitate with allowing the passage of fluid therethrough while preventing or blocking the passage of solids and the like, similar to the upper spaces 134 and/or the lower spaces 124 described herein.
The cover 100 may include a handle 146. As shown, the handle 146 may be a feature of the body 110. For example, the handle 146 may be a feature of the top 140. The handle 146 may provide a structure by which a user can pick up or otherwise handle the cover 100. In some embodiments, the handle 146 may allow a user to remove the lid 141 from the cover 100. For example, a user may grab the handle 146 to remove the lid 141 from the top 140. The handle 146 may also be used to put the lid 141 or other portions of the cover 100 back onto the cover 100.
The handle 146 may have a variety of shapes and sizes. As shown, the handle 146 may be an arc that extends away from the top 140. The handle 146 may be an arcuate shape extending upward as oriented from one or more of the top ribs 142. In some embodiments, the handle 146 may be a top rib 142 with a different contour than the other top ribs 142. As shown, the handle 146 may be partially flat on the ends with a middle portion that extends upward and in a generally arcuate shape. However, the handle 146 may extend upward in a variety of shapes and contours, such as square, rectangular, segmented, other polygons, other shapes, or combinations thereof. Therefore, the configuration shown and described is merely one possible implementation and other suitable configurations may be implemented.
The cover 100 may include an outer ring 150. The outer ring 150 may be a structure or structures configured to couple with the cover body 110 generally along the outer perimeter 125. The outer ring 150 may be arcuate in shape. The outer ring 150 may be a separable part of the cover 100 which may be removed therefrom and reattached thereto. The outer ring 150 may be arcuate when attached to the cover and either arcuate or other shapes, such as straight, when removed from the cover 100. When coupled with the cover 100, the outer ring 150 may be located a perpendicular distance R2 from the axis 10. When coupled with the cover 100, the outer ring 150 may have an outer surface that is located a perpendicular distance R2 from the axis 10. R2 may be a dimension equal to roughly half of the overall width of the outer ring 150. The distance R2 may be a radius of a circular outer ring 150. However, the outer ring 150 may not be circular, and thus in some embodiments the distance R2 may not be a radius. Further, R2 need not be constant as measured at different angular locations of the cover 100. For example, the outer ring 150 or other parts such as the skirt 120 may be arcuate but with straight outer edges such that the ring 150 or skirt 120 appears square or rectangular as viewed from the top. For such a shape, R2 would vary depending at which angular location the dimension is measured (i.e. which cross-section or side view is used to make the measurement). Thus, R2 may vary with such a configuration as measured at different angular locations. In some embodiments, R2 refers to a maximum or minimum width of the outer ring 126, or other outer portion of the skirt 1220. For a non-circular dome 126, R1 may be a maximum or minimum width, for example the maximum or minimum perpendicular distance from the axis 10 to respectively a farthest-most or closest portion of the outer ring 126, or other outer portion of the skirt 1220.
The outer ring 150 may be an elastic or otherwise flexible material. The outer ring 150 may expand to attach to various features of the cover 100 such as the outer perimeter 125 or other features. The outer ring may couple the ring body 110 with a mount 160, as described herein. The outer ring 150 may provide structural stability to various features of the cover 100 such as the outer perimeter 125. The outer ring 150 may include features that facilitate the flow of fluid through the cover 100 while preventing the flow of solids therethrough. In some embodiments, the outer ring 150 may include features that facilitate installation and securement of the cover 100.
The outer ring 150 may include a ring body 152. The ring body 152 may be a generally arcuate structure configured to couple with the cover 100, such as with the outer perimeter 125 of the skirt 120. In some embodiments, the ring body 152 may couple with the outer edge 129 of the skirt 120. The ring body 152 may at least partially cover the outer edge 129 and/or the outer perimeter 125 when coupled with the skirt 120. The ring body 152 may have a generally U- or C-shaped cross-section that extends in an arcuate manner and is swept out angularly about the central axis 110 (see
The outer ring 150 may include a variety of slots 153, holes 154, and/or openings 155. The ring body 150 may form or define these and other features. For example, various surfaces of the ring body may define inner surfaces of the slots 153, the holes 154, and/or the openings 155. As shown, the slots 153 may be elongated spaces within the ring body 152 and extending therethrough. The holes 154 may be generally circular spaces extending through the ring body 152. The openings 155 may be partially circular and partially linear spaces extending through the ring body 152. As shown, the slots 153 may be located along top and outer portions of the ring body 152 as oriented in the figure and in a generally arcuate configuration about the central axis 10. The holes 154 may be located more inwardly on the ring body 152 as oriented in the figure and in a generally arcuate configuration about the axis 10. The openings 155 may be located more outwardly on the ring body 152 as oriented in the figure and in a generally arcuate configuration about the axis 10. These arrangements and configurations of the slot slots 153, the holes 154 and the openings 155 are merely some examples, and a variety of configurations and arrangements of the various spaces may be incremented.
The slots 153, the holes 154, and/or the openings 155 may provide spaces through the ring body 152 that allow the passage of fluid therethrough while preventing the flow of solids therethrough. These spaces of the outer ring 150 may therefore improve the performance of the cover 100 through advantageous sizing and/or locating of the various spaces of the outer ring 150. The slots 153, the holes 154, and the openings 155 may be in fluid communication with the cavity 112. For instance, these spaces may be in fluid communication with the lower spaces 124 which may in turn be in fluid communication with the cavity 112. Thus, the cover 100 may allow for fluid flow through the outer ring 150 while preventing or reducing the flow of gravel or other debris through the outer ring 150.
The outer ring 150 may include one or more pockets 157. The pockets 157 may be located generally along the outer surface or services of the ring body 152 and an arcuate configuration about the axis 10. The pockets 157 may extend generally upward and form a recess therein. The pockets 157 may assist with handling the outer ring 150. In some embodiments, the pockets 157 may assist with assembling and/or disassembling the outer ring 150 with the ring body 110 and/or the mount 160. The pocket 157 may provide a surface for a user or tool to grasp or to pry the outer ring 150 into or out of place on the cover 100.
The outer ring 150 may not have any sharp edges. The edges of the various features of the outer ring 150 may therefore be rounded or otherwise smoothed. This may mitigate the chances of debris getting caught on the outer ring 150. The outer ring 150 may further by relatively shallow or short to mitigate the chances of debris getting caught thereon.
The cover 100 may include a mount 160. The mount 160 is partially visible in
As shown in
The angle A may be sized in order to optimize or otherwise facilitate the flow of fluid through the cover 100 while preventing the buildup of solids or other debris from blocking the flow of fluid through the cover 100. For example, the angle A may be relatively large such that a buildup of solids or other debris on or near the skirt 120 will still allow for the flow of fluid through the skirt 120. For instance, leaves and sticks or other debris may build up onto the skirt 120. By having a relatively large angle A, the buildup of debris on the skirt 120 will still allow the flow of fluid through the cover 100 due to gravity causing the fluid to drip through the buildup of debris and through the lower spaces 124 of the skirt 120. Therefore, the angle A may be sized such that such a buildup may be produced on top of or otherwise near the skirt 120 in order to allow the downward flow and/or dripping of fluid through the buildup and subsequently through the skirt 120, into the cavity 112 therein, and ultimately into the drain.
In some embodiments, the angle A is greater than or equal to 60°. However, the angle A may have a variety of sizes. In some embodiments, the angle A may be greater than or equal to 65°, greater than or equal to 70°, greater than or equal to 75°, greater than or equal to 80°, greater than or equal to 85°, or other smaller, intermediate or larger angular amounts. These are just some examples and are not limiting of the scope of this disclosure. For instance, in some contexts a larger angle A may be implemented that still produces the advantageous effects. For example, depending on the contour of the mounting structure to which the cover 100 is mounted or otherwise secured, the angle A may need to be less than 60°. In some embodiments, the angle A may therefore be less than 60°, such as 55°, 50°, 45° or other angular amounts.
While the angle A may be generally constant for the entirety of the skirt 120 about the axis 10, the angle A need not be constant. For example, the angle A may have one value at one angular location of the skirt 120 about the axis 10, and a different value at a different angular location of the skirt 120 about the axis 10. Therefore, a variety of configurations and arrangements of the skirt 120 related to the angle A may be implemented.
It is understood that the orientation of the skirt 120, such as the orientation of the lower ribs 122, may be described with respect to other geometric references or features of the cover 100. For instance, the orientation of the skirt 120 may be described with respect to the axis 10 or plane 15, or with respect to the mount 160, the sidewall 130, the top 140, and/or other features or references. The particular references and features used to describe the orientation of the skirt 120 or parts thereof are merely for convenience and are not meant to limit the scope of the disclosure.

The sidewall 130 may include the upper ribs 132 having sides 133. The sides 133 may be opposing sides or surfaces of the upper ribs 132. The sides 133 may partially define upper spaces 134 on either side of an upper rib 132. The distance between the sides 133 of the upper ribs 132 may define a width of the upper ribs 132. Further, the two sides 133 of the upper ribs 132 may be oriented in a variety of manners with respect to each other. In some embodiments, the sides 133 may be parallel to each other such that the upper rib 132 has a uniform width along the length of the upper rib 132.
In some embodiments, the two sides 133 of the upper rib 132 may not be parallel to each other such that the upper rib 132 does not have a uniform width along the length of the upper rib 132. As shown, the two sides 133 of a single upper rib 133 may be oriented at an acute angle C with respect to each other. The angle C may be sized so as to optimize or otherwise facilitate the flow of fluid through the cover 100. For example, the size of the angle C may be sized to optimize or otherwise facilitate the flow of fluid through the upper spaces 134 or other features of the sidewall 130. In some embodiments, the angle C may be 1°, 2°, 3°, 4°, 5°, 10°, 15°, 20°, or other intermediate, smaller or greater angular amounts.
Because the upper ribs 132 may define one or more surfaces of the upper spaces 134, the angle at which the sides 133 are oriented may affect the shape of the upper spaces 134. Therefore, the various surfaces defining the upper spaces 134 may have a variety of configurations and/or orientations. In some embodiments, the upper spaces 134 may be generally rectangular, as mentioned. In some embodiments, the upper spaces 134 may be trapezoidal, or other shapes. Further, the upper ribs 132 as mentioned may be coupled on one end with the lower portion 121 and on the opposite end with the upper perimeter 133. The upper ribs 132 may be wider on the end coupled with the lower portion 121 as compared with the end of the upper rib 132 coupled with the upper perimeter 133, or vice versa. Therefore, it is understood that the angle C may refer to either a thinning or widening upper rib 132 in the direction from the lower portion 121 to the upper perimeter 133

The overall height of the cover 300 as oriented in the figure may be about 4-5″. The cover 300 may have other heights as well, such as 1″, 2″, 3″, 6″, 7″, 8″, 9″, 10″, 15″ or other smaller, intermediate or greater heights. The overall width of the cover 300 as oriented in the figure may be from about 5″ to about 13″. The cover 300 may have other overall widths as well, such as 1″, 2″, 3″, 4″, 6″, 7″, 8″, 9″, 10″, 11″, 12″, 14″, 15″, 20″, 25″, 30″ 50″, or other smaller, intermediate or greater widths. These values for the overall width dimensions may apply to the dimension D2 shown in
The skirt 120 may similarly have a generally arcuate shape about the axis 10. The skirt 120 may provide an extended area that is greater than the area of just the drain, over which the cover 100 may be positioned. By “extended area” in this context, it is meant the two dimensional surface area that the skirt 120 “sweeps” out. Thus, the “extended area” is not limited to only the surface area of the top surfaces of the skirt 120, such as the top surfaces of the ribs 122. It also includes the area of the skirt 120 over any openings in the skirt 120, such as the spaces defined or formed by the ribs 122 or by other features of the skirt 120. This extended area may be approximately equal to the area of the skirt 120 as viewed from the top view as shown in
In some embodiments, the skirt 120 may provide an extended area that is greater than the area of the drain. The “area of the drain” here may refer to the overall general area covered by the draining region of the drain, which includes but is not limited to any openings in the drain. For example, the area of the drain may be based on the width W of the drain, discussed herein with respect to
R2 and R1 may also be expressed relative to each other. R2 may be expressed relative to a multiple of R1. Thus, for example, R2 may be at least twice R1, i.e. R2 may be greater than or equal to 2×R1. In some embodiments, R2 may be greater than or equal to 2.25×R1, R2 may be greater than or equal to 2.5×R1, R2 may be greater than or equal to 2.75×R1, R2 may be greater than or equal to 3×R1, R2 may be greater than or equal to 3.5×R1, R2 may be greater than or equal to 4×R1, etc. R2 may further be capped at a maximum amount. Thus R2 may be greater than or equal to 2×R1 but less than or equal to 3×R1. In some embodiments, R2 may be greater than or equal to 2×R1 but be less than or equal to 2.25×R1, less than or equal to 2.5×R1, less than or equal to 2.75×R1, less than or equal to 3.5×R1, less than or equal to 4×R1, less than or equal to 5×R1, etc. In some embodiments, R2 may be greater than or equal to 3×R1 but be less than or equal 3.5×R1, less than or equal to 4×R1, less than or equal to 5×R1, etc. These are merely some examples and the min or max value of R1 may be lower, intermediate, or greater multiples of R2 besides those explicitly given herein and some examples can also include the various ranges and sub-ranges between the various minimum and maximum values of R2 described above.
The increased area relative to the drain provided by the skirt 120 may increase the chances of draining surrounding fluids through the drain. This may be due in part because a shallow-sloped skirt 120 may allow debris to flow over and past the skirt 120, and further a larger area (as compared with the drain area) will now need to be covered or clogged. Therefore, not only may the orientation of the skirt 120 contribute to the effectiveness of the cover 100, but the overall area of the skirt 120 may contribute as well.
Some embodiments disclosed herein include a method of coupling a cover for a drain to a mounting surface, the method comprising: coupling the cover 100 to the mounting surface such that the cover at least partially surrounds the drain. In some embodiments, the cover 100 is coupled to the mounting surface via a mount 160 as described herein. In some arrangements, the drain has a half-width of R1 and wherein the cover 100 includes an arcuate dome defining a central axis and an arcuate skirt coupled with the dome and having an outer edge, wherein the skirt flares outward and downward from the dome to the outer edge in a first direction that is generally away from the central axis and generally away from the dome, wherein the first direction forms an acute angle A with a portion of the central axis that extends below the skirt, wherein the skirt forms a plurality of openings extending through the skirt, and wherein the outer edge of the skirt is located a perpendicular distance R2 from the axis, and wherein R2 is at least twice R1. In modified embodiments, R2 can be within the values and ranges described herein.
As shown, the lower ribs 122 may be oriented such that they extend radially with respect to the central axis 10. The lower ribs 122 and/or other features of the skirt 120 may be described as sweeping out an angle of 360° about the axis 10. Therefore, the skirt 120 may be described as sweeping out an angle of 360° about the axis 10. Similarly, the sidewall 130, the top 140, and or the outer ring 150 may be described as sweeping out an angle of 360° about the axis 10. By sweeping out an angle of 360° it is meant that the closed shape such as a circle or other rounded shape is formed about or generally about the axis 10. In some contexts, a cover 100 having a full 360° swept shape may be used over a drain on a mounting structure that has no interfering structures nearby, such as on an open part of the roof away from any walls of a building. However, in other contexts a drain may be located next to an interfering structure such as a wall, for example at the intersection of a roof and a wall on the roof. In these or other instances, less than 360° of swept out shape of the cover 100 may be implemented, as described in further detail herein for example with respect to
As shown in
The lower ribs 122 may include a first end 122A. The first end 122A may couple the rib 122 with the lower portion 121. The lower ribs 122 may also include a second end 122B. The second end 122B may be located on an end of the lower rib 122 that is opposite from the first end 122A. The second end 122B of the lower ribs 122 may couple the lower ribs 122 with the outer perimeter 123 (only partially visible in
As shown, the sides 123 of the rib 122 may be oriented with respect to each other at an acute angle D. The angle D may be sized so as to optimize or otherwise facilitate the flow of fluid through the skirt 120 and to prevent the flow of solids therethrough. The angle D may be chosen such that the lower spaces 124 defined by the skirt 120 are optimized in this manner. As shown, the first end 122A may be relatively thinner or less wide than the second end 122B of the lower rib 122, such that the angle D between the sides 123 is measured as shown in
Further shown in
In embodiments where the widths of the first end 124A and of the second end 124B are not equal, the lower space 124 may be defined with respect to the angle E as indicated. The angle E may be an angle defined by two opposing sides 123 of two adjacent lower ribs 122 that partially define the lower space 124 therebetween. The angle E may apply equally to lower spaces 124 where the first end 124A is wider than the second end 124B, and vice versa. In some embodiments, the angle E may be 1°, 2°, 3°, 4°, 5°, 10°, 15°, 20°, or other intermediate, lower or higher angular amounts. Further, the angle E may be the same for each of the lower spaces 124. However, in some embodiments the angle E may be different for different lower spaces 124. Therefore, one of the lower spaces 124 may have a first value for the angle E, while another lower space 124 may have a different value for the angle E.
The cover 100 may have a diameter D1 and an overall diameter D2. The diameter D2 may be a distance perpendicular to the axis 10 from one end of the cover 100 to the opposite end. The diameter D1 may be a distance perpendicular to the axis 10 from one end or region of the lower portion 121 to the opposite end or region of the lower portion 121. By “diameter” in this context it is understood that this may refer to an ordinary diameter of a circle, but that it may also refer to the width of a non-circular cover 100, such as the major or minor axis of an elliptical cover 100. Therefore, the nomenclature of the diameter D2 is not meant to limit the cover 100 to any particular shape. Further, the diameters D1 and D2 may vary when measured at different angular locations, for instance with an elliptical cover 100.

The mount 160 may include a mount body 162 as shown. The body 162 may have a generally circular shape swept out for a full 360° about the axis 10. In some embodiments, the mount body 162 may be swept out for less than 360°.
The mount 160 may include one or more mount surfaces 163. The mount surfaces 163 may be arcuate and generally flat structures extending along the boundary of the mount 160. The mount surfaces 163 may provide structural stability to the mount 160. For example, the mount surfaces 163 may provide increased stiffness to the mount 160. As shown, there may be six mount surfaces 163. In some embodiments, there may be fewer or more mount surfaces 163. In some embodiments, the mount surfaces 163 may be adjacent to each other. As shown, the mount surfaces 163 may be interspersed with intervening structures therebetween.
The mount 160 may include one or more flex joints 164. The flex joints 164 may be located in between adjacent mount surfaces 163. The flex joints 164 may provide flexibility to the mount 160 such that it can be secured to curved or other non-flat mounting structures or protuberances. The flex joint 164 may include a tab 166 having a hole 169 extending therethrough. The tab 166 may be an arcuate and generally flat structure extending for a portion of the contour of the mount 160. In some embodiments, the tab 166 may be similar to the mount surfaces 163. For instance, the tab 166 may be a shortened version of the mount surfaces 163. The hole 169 extending through the tab 166 may be generally parallel with the axis 10. In some embodiments, the whole 169 may not be parallel with the axis 10. The hole 169 may be configured to receive a fastener such as a nail or rivets therethrough in order to secure the amount 160 to or otherwise with a mounting structure. The hole 169 may be circular as shown, or it may have other suitable shapes. The tab 166 may be separated from adjacent mount surfaces 163 on either side by a gap 168. The gap 168 may be a space in between the mount surfaces 163 and the tabs 166. The gaps 168 may partially provide flexibility to the flex joint 164 such that the mount 160 may be secured to a curved or other non-flat mounting structure. The size of the gaps 168 may be chosen so as to optimize this flexing capability. In some embodiments, the gap 168 may have a width of 0.1″, 0.2″, 0.125″, 0.25″, 0.5″, or other intermediate, lower or greater amounts. As shown, the gaps 168 may extend along most of the length of an interface between the tab 166 and the adjacent mount surface 163.
The mount 160 may include a lip 170. The lip 170 may be an arcuate structure extending along an outer boundary of the mount 160. The lip 170 may provide structural stability to the mount 160. For instance, the lip 170 may provide increased stiffness to the mount 160. The lip 170 may couple with and project upwardly from the mount surfaces 163. The lip 170 may therefore form a wall structure around the boundary of the mount 160. The lip 170 may be flexible such that it can flex to couple with the body 110 of the cover 100. In some embodiments, the lip 170 may be expandable and contractible to fit around and/or cover and then compress onto the outer perimeter 125. The lip 170 may be formed from a variety of suitable materials, including plastics, polymers, composites, metals, other materials or combinations thereof. There may be multiple segments that form the lip 170. As shown, the lip 170 may be formed of eighteen segments. The segments together may form the lip 170. In between the segments of the lip 170 there may be openings 172. The openings 172 may be spaces in between the segments of the lip 170 that increase the flexibility of the lip 170. In some embodiments, the mount 160 may be secured to a curved or other non-flat mounting structure, and the openings 172 may allow for short segments of the lip 170 which may provide more flexibility to the mount 160 than longer segments. The openings 172 may be a variety of sizes and shapes. In some embodiments, the openings 172 may be rectangular spaces in between the segments of the lip 170. The openings 172 may have a width from one segment of the lip 170 to an adjacent segment of the lip 170. This width may be 0.01″, 0.1″, 0.2″, 0.3″, 0.4″ 0.5″, 0.75″ or other intermediate, lower or greater values.
As shown, the cover 300 may include one or more ribs 322 that extend from the skirt 320 to the upper portion 330. Thus, the upper portion 330 and the skirt 320 may include different parts of the same rib 322. The ribs 322 may further extend to the top 340. Similarly, one or more spaces 324 defined in part by the ribs 322 may extend from the skirt 320 to the upper portion 330. The spaces 324 may further extend to the top 340. The top 340 of the cover 300 may be generally flat as shown. The top 340 may therefore not have any openings or ribs at a location generally near the center of the top 340.
The cover 400 and the various features thereof may be swept out about the axis 10 for an amount equal to a rotation angle 12. As shown, the cover 300 and the various features and parts thereof, may be swept out angularly about the axis 10 for a rotation angle 12 of 180°. As mentioned, by “swept” it is meant that the various parts of the cover 400 may extend in a generally arcuate contour about the axis 10. This contour may be circular as shown. In some embodiments, this contour may be elliptical, oval, circumferential, rounded, or other arcuate paths. Further, the rotation angle 12 may be greater or less than 180°. In some embodiments, the rotation angle 12 may be less than 360°, less than or equal to 270°, less than or equal to 180°, less than or equal to 90°, or any other intermediate, lower or higher angular amount.
In embodiments of the cover 400 that are swept out for a rotation angle 12 that is less than 360°, there may be exposed end surfaces of the various features of the cover 400. As shown, the cover 400 may have mating surfaces 451, 461, 411, 431, 441 on both ends of the swept out cover 400. The mating surface 451 may be an end surface or surfaces of the outer ring 450. The mating surface 461 may be an end surface or surfaces of the mount 460. The mating surface 411 may be an end surface or surfaces of the lower portion 420. The mating surface 431 may be an end surface or surfaces of the upper portion 430. The mating surface 441 may be an end surface or surfaces of the top 440. These mating surfaces 451, 461, 411, 431, 441 may mate with an adjacent structure. By “mate” it is meant that these surfaces may abut, contact, be fastened to, or be near such adjacent structures. For instance, these surfaces may abut a wall protruding upwardly from the mounting structure to which the cover 400 is secured.
The mating surfaces 451, 461, 411, 431, 441 may form contours 470, 472. The contours 470, 472 refer to the shape formed or defined by the various mating surfaces. The first contour 470 may be formed by the mating surfaces 451, 461, 411, 431, 441 on one end of the swept out cover 400, and the second contour 472 may be formed by the mating surfaces 451, 461, 411, 431, 441 on the other end of the swept out cover 400. As shown, the two contours 470, 472 may each be planar. The first contour 470 may define a first plane 471. The second contour 472 may define a second plane 473. As shown, the first and second planes 471, 473 may be coplanar. In some embodiments, the first and second planes 471, 473 may be non coplanar. Either or both of the first and second planes 471, 473 may intersect the axis 10. As shown, the axis 10 may reside within both of the first and second planes 471, 473. In some embodiments, the axis 10 may intersect one, both or neither of the planes 471, 473 at a single point. For instance, one or both of the planes 471, 473 may be angled with respect to the axis 10, such as when the cover 400 is configured to abut against an angled, protruding structure. In some embodiments, the contours 470, 472 may not be planar. One or both of the contours 470, 472 may be non planar. For example, the contour 470 may be curved or otherwise shaped in order to complement an adjacent structure to which it is mated. Some examples of structures to which the various covers herein may be mated are shown and described herein, for example with respect to

In some embodiments the covers disclosed herein may have adjustment mechanisms that allow the covers to conform or otherwise adjust to the surface or surfaces of an adjacent structure. As shown in
As shown, the mechanism 680 may include one or more fingers 682. The fingers 682 may retractably extend from the mechanism 680 and toward the adjacent structure 601. As shown, the fingers 682 may be located along the boundary of the interface 670 between the cover 600 and the adjacent structure 601. The fingers 682 may be of varying length. The fingers 682 may extend from the mechanism 680 for a variable length to match the contour of the adjacent structure 601. The fingers 682 may extend and thereby form or define spaces in between. The extended fingers 682 may act as an extension of one or more various parts of the drain over the gap in between the adjacent structure 601 and the cover 600. As shown, the fingers 682 may provide an extended dome of the cover 600. In some embodiments, the finger 682 may provide an extended skirt of the cover 600. The fingers 682 may be formed from a variety of materials. The fingers 682 may be relatively rigid members formed from plastics or polymers. In some embodiments, the fingers 682 may be formed from metals, metal alloys, composites, other suitable materials, or combinations thereof. The fingers 682 may be relatively flexible members formed from a variety of materials, such as flexible plastics or polymers. In some embodiments, the fingers 682 may be formed from mesh material, flexible porous materials, other suitable flexible materials, or combinations thereof. Further details of the adjustment mechanism are discussed herein, for example with respect to

The foundation 763 may have a top side as oriented configured to couple with the body of the cover 700, and a bottom side opposite the top side configured to mount, secure, attach or otherwise couple with a mounting structure, such as the mounting structure 502 and 603 described herein. The bottom side of the foundation 763 may couple with a mounting structure in a variety of ways. In some embodiments, the foundation 763 may include one or more tabs, such as the tab 166 described with respect to
As shown in
The outer ring 750 may include a plug 758. The plug 758 may be coupled with an interior surface of the ring body 752 and extend away from the ring body 752 toward the center of the outer ring 750. The plug 758 may be a generally rectangular or trapezoidal projection. As shown, the plug 758 may have a wider base near the ring body 752 and then get progressively narrower therefrom. The plug 758 may be configured to couple with corresponding features of the cover body, such as the lower ribs 722 and/or the lower spaces 724. The plug 758 may be received by these or other structures to secure the outer ring 750 to various features of the ring body such as the lower portion 720, including the lower ribs 722 and/or the lower spaces 724. The plug 758 can include one or more stops 756. The stops 756 may be generally planar protrusions that extend away from the various surfaces of the plug 758 to which the respective stops 756 are coupled. As shown, there may be two stops 756, with one stop 756 located on a top surface of the plug 758 as oriented in the figure and the other stop 756 located on a bottom surface of the plug 758 as oriented. The plug 758 with the stops 756 may be inserted into or otherwise received by a corresponding receiving structure of the ring body. The stops 756 may prevent the plug 758 from backing out of the receiving structure. The stops 758 may flex such that they may bend when the outer ring 750 is secured with a receiving structure, and they may straighten out in an unrestrained state for instance when not secured with the receiving structure.

The mount 760 may include multiple catches 765. As shown, there may be four catches 765. There may be fewer or more catches 765, such as one, two, three, five, six, seven, eight, nine, ten or more catches 765. The catches 765 may be located symmetrically about the mount 760. The catches 765 may be located asymmetrically about the mount 760. As shown, there may be segments of the foundation 765 having the catch 765 and adjacent segments of the foundation 765 not having the catch 765.
The adjustment mechanism 880 may include features for conforming or otherwise adjusting the cover 800 or parts thereof, such that it forms a portion of the cover between the cover 800 and an adjacent structure 801, such as a wall. The mechanism 880 may have a rack 881 coupled with the cover 800. As shown, the rack 881 may be coupled with the dome 826. The rack 881 may provide a frame or other supporting structure for the mechanism 880. The rack 881 may be formed from a variety of materials. The rack 881 may be include one or more relatively rigid members formed from plastics or polymers. In some embodiments, the rack 881 may be formed from metals, metal alloys, composites, other suitable materials, or combinations thereof. The rack 881 may be relatively flexible formed from a variety of materials, such as flexible plastics or polymers. In some embodiments, the rack 881 may be formed from mesh material, flexible porous materials, other suitable flexible materials, or combinations thereof.
The rack 881 may include one or more fingers 882. The fingers 882 may have any or all of the same or similar features and/or functionalities as the fingers 682 described herein with respect to the cover 600. The rack 881 and/or fingers 882 fingers 882 may extend outward away from the cover 800 to cover any gap in between the cover 800 and the adjacent structure 601. As shown, the rack 881 and fingers 882 are in a retracted configuration. They may extend outwardly therefrom as described. The rack 881 and fingers 882 may be configured in a substantially square shape as shown.

The distances W1, W2, W3 and W4 may be a radius. However, the upper portion 1071, intermediate portion 1081, lower portion 1091 and outer edge 1099 need not be circular, and thus in some embodiments the distances W1, W2, W3 and/or W4 may not be a radius. W1, W2, W3 and W4 may be measured perpendicularly from the axis 10 to any region of the respective portion or edge, including to regions of the portions or edge that are relatively closer or farther from the axis 10 than other regions of the portions or edge. Further, the dimensions W1, W2, W3 and W4 of the cover 1000 need not be constant as measured at different angular locations about the axis 10. For example, the portions 1071, 1081, and 1091 or outer edge 1099 may be arcuate but with straight outer edges such that the cover 1000 appears square, rectangular, other polygonal shapes, etc. as viewed from the top. For such a shape, W1, W2, W3 and W4 would vary depending on which angular location the dimension is measured. Thus, W1, W2, W3 and W4 may vary as measured at different angular locations about the axis 10.

Additionally, many modifications may be made to adapt a particular situation to the teachings of claimed subject matter without departing from the central concept described herein. Therefore, it is intended that claimed subject matter not be limited to the particular embodiments disclosed, but that such claimed subject matter may also include all embodiments falling within the scope of the appended claims, and equivalents thereof.
It is contemplated that various combinations or subcombinations of the specific features and aspects of the embodiments disclosed above may be made and still fall within one or more of the inventions. Further, the disclosure herein of any particular feature, aspect, method, property, characteristic, quality, attribute, element, or the like in connection with an embodiment may be used in all other embodiments set forth herein. Accordingly, it should be understood that various features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the disclosed inventions. Thus, it is intended that the scope of the present inventions herein disclosed should not be limited by the particular disclosed embodiments described above. Moreover, while the inventions are susceptible to various modifications, and alternative forms, specific examples thereof have been shown in the drawings and are herein described in detail. It should be understood, however, that the inventions are not to be limited to the particular forms or methods disclosed, but to the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the various embodiments described and the appended claims. Any methods disclosed herein need not be performed in the order recited.
The ranges disclosed herein also encompass any and all overlap, sub-ranges, and combinations thereof. Language such as “up to,” “at least,” “greater than,” “less than,” “between,” and the like includes the number recited. Numbers preceded by a term such as “approximately”, “about”, “up to about,” and “substantially” as used herein include the recited numbers, and also represent an amount or characteristic close to the stated amount or characteristic that still performs a desired function or achieves a desired result. For example, the terms “approximately”, “about”, and “substantially” may refer to an amount that is within less than 10% of, within less than 5% of, within less than 1% of, within less than 0.1% of, and within less than 0.01% of the stated amount or characteristic. Features of embodiments disclosed herein preceded by a term such as “approximately”, “about”, and “substantially” as used herein represent the feature with some variability that still performs a desired function or achieves a desired result for that feature.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.
It will be understood by those within the art that, in general, terms used herein, are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced embodiment recitation is intended, such an intent will be explicitly recited in the embodiment, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the disclosure may contain usage of the introductory phrases “at least one” and “one or more” to introduce embodiment recitations. However, the use of such phrases should not be construed to imply that the introduction of an embodiment recitation by the indefinite articles “a” or “an” limits any particular embodiment containing such introduced embodiment recitation to embodiments containing only one such recitation, even when the same embodiment includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce embodiment recitations. In addition, even if a specific number of an introduced embodiment recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, embodiments, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
Although the present subject matter has been described herein in terms of certain embodiments, and certain exemplary methods, it is to be understood that the scope of the subject matter is not to be limited thereby.
