Abstract
A storm drain filter assembly includes a frame and several rows of bristles extending down from a top rail of the frame. The frame can be positioned next to a storm drain with the bristles blocking debris from entering the drain while allowing water to flow into the drain. As the frame is lowered toward the ground in front of the drain, brackets on the back of the frame slide between the storm drain surface and other brackets that have been affixed to the storm drain surface, so that when the frame rests on the ground with the bristles covering the storm drain, it is retained in place by the brackets. The frame assembly can be removed simply by lifting the frame up and away from the storm drain.
Description
- This application is related to co-pending U.S. patent application Ser. No. 10/980,941, filed Nov. 3, 2004 and Ser. No. 11/343,150, filed Jan. 30, 2006, incorporated herein by reference.
- The present invention relates generally to storm drain filters.
- The above-referenced applications discuss the need for storm drain filters, and the inadequacies of conventional methods such as rock bags for blocking debris and unwanted substances from entering storm drains, where the debris and unwanted substances can drain into the environment. As understood here, the principles of the above-referenced applications can be used to provide an easily installable and removable storm drain filter that his effective in preventing debris and unwanted substances from entering storm drains.
- A storm drain filter assembly includes a frame that is configured for extending substantially across a storm drain, and plural bristles are supported by the frame in a vertical orientation when the frame is positioned to cover a storm drain. One or more frame brackets are attached to the frame and respective drain brackets can be affixed to a storm drain surface adjacent a storm drain. With this structure, the frame with bristles can be lowered by a person toward the street next to the storm drain such that, when the drain bracket is affixed to the storm drain surface, the frame bracket engages the drain bracket to hold the frame in front of the storm drain without further connecting structure and with the bristles substantially blocking the storm drain.
- In non-limiting embodiments the frame bracket is slidable between the drain bracket and the storm drain surface. Thus, the frame bracket can be disposed between the drain bracket and the storm drain surface, with the frame being configured such that a portion of the frame rests on the ground. If desired, a seal can be engaged with the frame and disposed against the storm drain surface when the frame bracket is engaged with the drain bracket.
- In non-limiting implementations two drain brackets are provided and can be affixed to the storm drain surface at opposed ends of the storm drain. First and second frame brackets are engaged with opposed end portions of the frame such that the frame brackets engage respective drain brackets. One non-limiting frame bracket can be established by a parallelepiped-shaped plate that is affixed to the frame with a portion of the plate extending past the frame, while a non-limiting drain bracket can establish a space between the storm drain surface and the drain bracket, with the portion of the frame bracket plate that extends past the frame being disposed in the space.
- In another aspect, a method for blocking debris from entering a storm drain while permitting water to flow into the drain includes affixing at least one drain bracket to a storm drain surface adjacent the storm drain, attaching at least one frame bracket to a frame supporting plural bristles, and lowering the frame toward the storm drain such that a bottom portion of the frame rests on the ground, the bristles cover the storm drain, and the brackets engage each other to substantially prevent lateral motion of the of frame relative to the storm drain while permitting the frame to be lifted up and away from the storm drain.
- In another aspect, a frame assembly for a storm drain defined by a drain opening bounded by a storm drain surface includes one or more drain brackets affixed to the storm drain surface. A frame is sized and configured substantially like the drain opening, and the frame is associated with means for blocking the drain opening to solid matter but substantially not to prevent water from flowing into the drain opening. One or more frame brackets are coupled to the frame. Each frame bracket is engaged with a respective drain bracket to hold the frame adjacent the storm drain surface with the bristles juxtaposed with the drain opening.
- The details of the present invention, both as to its structure and operation, can best be understood in reference to the accompanying drawings, in which like reference numerals refer to like parts, and in which:
-
FIG. 1 is a perspective view of the drain brackets affixed to the storm drain surface; -
FIG. 2 is a perspective view of a storm drain cover showing fastening rivets in an exploded relationship to the frame; -
FIG. 3 is a perspective view of an alternate storm drain cover in which the frame brackets are shown twice for clarity, once as they appear when attached to the frame and also in an enlarged exploded view to better illustrate their structure; and -
FIG. 4 is a perspective view showing details of the bristle mounting structure for the drain cover inFIG. 3 , with portions cut away and with the bristles with base in an exploded relationship with the frame. - Referring initially to
FIG. 1 , astorm drain 10 includes astorm drain surface 12, typically the vertical face of a street curb, that bounds adrain opening 14 through which water can flow to a sewer. The filter of the present invention is intended to cover theopening 14 in a way that permits water to flow into the sewer but substantially prevents debris and other undesirable matter from entering the sewer. - To mount the present filter in front of the
drain opening 14, one or more mounting members can be affixed to thedrain surface 12 more or less on opposite sides of thedrain opening 14 as shown. In the embodiment shown, twobrackets 16 are affixed to thedrain surface 12 using an adhesive such as “Gorilla” glue, it being understood that other means for mounting thebrackets 16 such as fasteners can be used. Adhesion is preferred to permit relatively easy removable of thebrackets 16 if desired. - The non-limiting brackets shown each include two parallelepiped-shaped front and
rear elements 18, 20 made of metal, ceramic, or hard plastic. Theelements 18, 20 may be sized and shaped identically to each other, and are held flush together in the overlapping configuration shown by any suitable means such as glue or more preferably rivets 22 or fasteners. Accordingly, it may be appreciated that the entire rear surface of therear element 20 may be positioned flush against thedrain surface 12 and adhered or otherwise affixed thereto, with aportion 24 of the front element 18 extending past therear element 20 to establish aspace 26 between theportion 24 anddrain surface 12. - While
FIG. 1 shows twobrackets 16 advantageously mounted on thedrain surface 12 above thedrain opening 14, it is to be understood that greater or fewer brackets can be used and mounted on other locations of thedrain surface 12 if desired, even, less optimally, on the top of the drain surface (i.e., the sidewalk). - Attention is now directed to
FIG. 2 , which shows a filter, generally designated 30, that includesplural bristles 32 supported on aframe 34. In one non-limiting embodiment, theframe 34 may include opposedvertical struts 36 that can be hollow parallelepiped-shaped metal or hard plastic structures (e.g., without limitation, fiberglass-reinforced resin) the bottoms ends of which can be connected together by abottom beam 38. A rubber orplastic gasket 40 or other sealing element can be glued or otherwise adhered to thebottom beam 38 and/or to thestruts 36. - The above-referenced patent applications describe various configurations of the
bristles 32, e.g., that they can be arranged in dense rows and made of polypropylene, and methods for engaging thebristles 32 with theframe 30, e.g., by first supporting thebristles 32 at their lower and/or upper ends by apanel beam 42 and then engaging the panel beam with a frame. All of these methods and structures disclosed in the above-referenced patent applications are incorporated herein. - Of particular relevance to the present invention is that the frame is provided with structure for engaging with curb-mounted structure (e.g., drain brackets 16) to hold the frame in front of the storm drain without further frame-to-curb connecting structure and with the
bristles 32 substantially blocking the storm drain, i.e., extending from one side of the drain to the other and extending from the top of the drain opening to near or at the bottom (street). In the exemplary non-limiting embodiment shown, first andsecond frame brackets 44 are engaged with opposed end portions of theframe 30 as shown, preferably onopposed struts 36 adjacent thetop beam 42. As further shown, eachframe bracket 44 is established by a parallelepiped-shaped plate that is affixed to the frame (e.g., byrivets 46 or glue or other fasteners), with aportion 48 of the plate extending outwardly laterally past theframe 30. - Accordingly, with the above-described combination of structure, the
frame 30 can be lowered by, e.g., a person toward the storm drain such that thebottom beam 38 of theframe 30 rests on the ground, thebristles 32 cover the storm drain opening, and eachframe bracket 44 engages arespective drain bracket 16 to substantially prevent lateral motion of the offrame 30 relative to the storm drain while permitting theframe 30 to be lifted up and away from the storm drain when desired. In greater detail, as the frame is lowered in front of the storm drain, theportion 48 of eachframe bracket 44 slides down into thespace 26 that is between thedrain surface 12 and theoverlap portion 24 of the front element 18 of therespective drain bracket 16. With theframe 30 in place as intended herein, theframe 30 extends substantially across the storm drain and thebristles 32 are in a vertical orientation. Preferably, the height above the ground of theframe brackets 44 when the filter is positioned as described equals the height above the ground of thedrain brackets 16, so that theoverlap portion 48 of eachframe bracket 44 rests in itsspace 26 more or less flush against theoverlap portion 24 of therespective drain bracket 16. Thegasket 40 faces and preferably abuts thestorm drain surface 12. -
FIG. 3 shows astorm drain cover 100 that is in all essential respects identical to thecover 30 shown inFIG. 2 , except that instead of two single-plate frame brackets 44, thecover 100 shown inFIG. 3 has two right angle frame brackets 102 (each one being shown twice for illustration, once as attached to the frame and once in an enlarged exploded relationship with the frame). Afastening side 104 of each L-shapedframe bracket 102 is attached to aframe 106 and more particularly in a non-limiting embodiment to a respective vertical strut of the frame by, e.g., rivets 108, while anengagement side 110 of eachframe bracket 102 extends laterally inward beyond the respective frame strut and is distanced fromother drain 100 structure as shown such that the engagement sides 110 can slide down into thespace 26 that is between thedrain surface 12 and theoverlap portion 24 of the front element 18 of therespective drain bracket 16 as described previously. - If desired, the
drain cover 100 can have ahollow bottom rail 120 and bristles 122 can be free at their top ends and can be supported by thebottom rail 120 as shown inFIG. 4 . Specifically, thebristles 122 can be heat fused into asolid polypropylene base 124 that preferably is of the same cross-section as the channel in thehollow bottom rail 120. Accordingly, the base 124 can be slid into thebottom rail 120 of the frame. U.S. Pat. No. 5,819,357, incorporated herein by reference, discloses polypropylene bristles that can be used as the bristles shown herein. - While the particular STORM DRAIN FILTER is herein shown and described in detail, it is to be understood that the subject matter which is encompassed by the present invention is limited only by the claims.
