Roof scupper overflow with sensor

Abstract

The roof scupper overflow with sensor cooperatively engages and replaces a conventional roof opening through a wall or in a corner to prevent trash from reaching and clogging the conventional roof basket and drain. Accumulating trash builds up on the screen of the roof scupper overflow causing a foam float or buoy connected to a trash tray to rise permitting water to run under the trash trap at roof level. The trash tray is retained to a base with magnets. When the water reaches a predetermined level, the foam buoy rises pulling the trash tray away from the base allowing water to flow to the conventional roof drain basket and activating a magnet switch sending a signal to overflow sensor and a control module connected to WIFI service.

Like numbers refer to like elements throughout.

(19) The present invention includes a water level sensor attached to the trash tray for indicating a selected volume of water has accumulated on the roof, a communication system disposed within a housing positioned on the on support member above the drain for transmitting measurement data received from the water level sensor.

(20) FIGS. 1-8 show the roof scupper overflow 10 and WIFI sensor module 15 showing an base plate 14 for attachment to a roof. The base plate 14 attaches to the roof having a watertight seal with the surface of the roof formed by sealing with a sealant such as a caulk or adhesive and is stripped in with the roofing, materials which are consistent with those used on the roof. The base plate may include four spaced apart aligned holes around the outer periphery for affixing to the roof support structure.

(21) The roof scupper overflow 10 base plate 14 is affixed to the roof forming a water tight seal with the roof. The roof scupper overflow includes a rectangular upright frame 12 mounted to the base plate 14 having opposing vertical elongated frame side members 7 having top distal ends connecting to an elongated top bar 9. The WIFI sensor module 15 with batteries is supported on the top bar 9 and includes means for electrically connecting to a magnetic switch.

(22) A rectangular sliding housing 3 is disposed between the base plate 14, elongated side members 7 and top bar 9 of the scupper overflow frame 12. The slidable housing 3 slidably engages the frame 12 to move up and down within the frame. The slideable housing 3 includes a bottom defining a trash tray or a sieve tray 16 and a pair of aligned opposing housing sidewalls 19, 21 having a bottom edge 22 connecting to the outside edges of the sieve tray. The opposing housing sidewalls 19, 21 include an inwardly extending front flange 23 and rear flange 24 extending along the vertical outer edges. A top flange 25 extends inwardly from the top edges of the side flanges and may optionally attached at the end edges to the upper end edge of the opposing side flanges.

(23) The base plate 14 supports a sieve tray 16 serving as a trash tray. The sieve tray 16 comprises an rectangular plate having teeth 18 projecting from the periphery thereof and which may be up-turned around the edges forming an up-turned rake. The sieve tray 16 includes openings 20 therethrough, for example, a plurality of perforations such as slits or holes therethrough. One preferred embodiment includes a sieve tray comprising a rectangular plate having a plurality of teeth projecting from the periphery thereof extending forward or up-turned along the front edge and a plurality of perforations such as slits or holes therethrough. Magnetic means comprising one or more magnets 26 or magnetic strips are mounted onto the bottom surface of the sieve tray in magnetic engagement with a steel base plate or a magnetic or steel strip 27 affixed to a top surface of a non-metallic base plate; or alternatively one or more magnets or magnetic strips are mounted onto the top surface of the base plate in magnetic engagement with a steel sieve plate or a magnetic or steel strip affixed to non-magnetic bottom surface of the sieve tray.

(24) The rectangular foam block forming a closed cell foam buoy 28 extends from one housing sidewall to the opposing housing sidewall and is slidably held between the housing sidewall flanges and the housing top flange 25. The foam buoy may be composed of STYROFOAM having a coating or comprise and air filled buoy or a container filled with particles of cork, foam, or other material which floats on water. The foam buoy is spaced above the sieve tray positioned near the front of the scupper. In one preferred embodiment, the foam buoy 28 lower inner wall portion 36 attaches to an upper screen portion 38. Floating of the foam buoy 28 raises the screen 30 and sieve plate 16 attached thereto.

(25) A screen extends across the bottom portion of the front end, (the water entrance) of the housing, extending from the opposing housing sidewalk a selected height from the bottom and with the bottom of the screen affixed to the top surface of the sieve tray and the top of the screen affixed to the bottom of the buoy.

(26) The vertically positioned screen 30 is contiguous to the sieve plate and spaced apart a selected distance from the inner edge affixed to an inner solid portion surface of the sieve plate. The screen preferably comprises inch screen for catching leaves or trash disposed between the buoy made of foam and the sieve tray trash tray. It is contemplated that screens having a mesh size ranging from inch to 1 inch can be utilized with the roof scupper and that multiple screens could be mounted in a frame each screen having different size mesh. The screen preferably comprises inch screen for catching leaves or trash disposed between the buoy made of foam and the sieve tray trash tray.

(27) The foam buoy 28 comprising a foam material has a lower inner wall portion attaching to an upper screen portion 38. Floating of the foam buoy 28 raises the screen 30 and sieve plate 16 attached thereto. By utilizing the screen together with the sieve tray, debris blocking the flow of water is lifted up with the sieve tray, rather than being able to accumulate under the sieve tray. The steps enable the float and sieve tray to lower upon drainage of the water to an acceptable level, whereby water flows under the sieve tray supported by the steps.

(28) A pair of opposing side screens 40 are supported by a slotted side arm 42 and connecting top arm 44 and bottom arm 45 forming side screen panels 46 mounted to the frame 12. Side screen panels 46 are affixed between the adjustable arms 42 projecting from the sides of the frame and can be mounted at a selected angle to the roof curb or sidewall or rim or flange surrounding a flat roof to prevent debris from moving around the roof scupper. The side screens are as high as the top of the roof scupper device. It is contemplated the arms may be hinged or the screens may be pliable and bent into position for affixation to the existing roof rim or curb.

(29) The WIFI sensor module 15 is supported by the top bar 9 whereby the WIFI (including transmitter and receiver) and magnetic switch module 40 is spaced apart from and mounted on the housing flange 23 and frame. Wires 46 extend from the WIFI module down the frame members to a pair of spaced apart opposing magnetic switches 60 affixed to a top surface of the inner edge portion of the base which hold the sieve plate thereto until a sufficient level of water floats the buoy. At least one magnet 48 is affixed to the top surface of the sieve tray and is in magnetic communication and cooperative engagement with the magnet switch extending from wires mounting to the base plate.

(30) At least one sieve tray support magnetic members 50 may be spaced apart in opposed alignment on the top portion adjacent the inner edge of the top bar of the frame to support the sieve tray 16, buoy 28, and screen 30 so that when water rises and the buoy floats upward pulling the sieve tray up whereby the housing 3 includes magnets or magnetic strip material 27 which cooperatively engages magnets of magnetic material 50 on the frame top bar 9 as shown by the arrows 34 in FIG. 2 until the level of the water subsides and the scupper is reset. The base plate may be composed of a magnetic material such as steel or have magnets or magnetic material strips or pads such as steel disposed onto the surface thereof for cooperative magnetic engagement with opposing magnets affixed to the underside of the sieve tray 16 or for cooperative engagement with a sieve tray 16 composed of a magnetic material. Magnetic pads or magnets positioned on the lower surface of the frame top bar 9 magnetically engage magnets or magnetic material on the top surface of the housing to hold the screen and sieve tray and debris up and let water pour through below in clogged drain situations.

(31) The perforated barrier such as the cylindrical screen 30 attaching to the lower portion of the inner wall of the buoy allows the buoy to rise when the water level rises and lifts the buoy, screen and sieve tray to permit the water to discharge through the cavity below the housing, in addition the raising of the buoy completes a circuit to send a text and email or other communication to create an alert to a maintenance group to enable a roofing company or plumber to investigate, fix, and/or repair the drain system.

(32) The overflow sensor in the module monitors the condition of the backup roof drainage system and immediately notifies a building owner (or tenant), maintenance, or designated party by electronic means such as an text, electronic mail, audio, and/or visual message via WIFI if the backup roof drainage system is called upon to convey water from a building's roof. The sensor may also indicate if the batteries powering the system are depleted. The monitor is shown installed in a housing powered by batteries and/or a solar panel on a support structure over the drainage device above the water level in electrical communication with sensors attaching to the trash tray which are in electrical communication with magnets holding the trash tray to the base plate.

(33) Once the magnets are separated by the float apparatus during a high water condition, the sensor sends a signal to the receiver such as a smart phone, tablet, computer or other electrical device notifying a selected individual that it is likely that the primary drain and/or the primary roof drainage system has malfunctioned and/or is plugged by debris. The building maintenance person can take the necessary steps to remedy the problem or problems with the primary drain and/or drainage system

(34) The overflow sensor comprises a housing, a magnet, a water flow sensor, and a control module which is disposed in the housing. The control module is operatively in communication with the water flow sensor. In the illustrated embodiment, such communication is performed by leads or wires that couple the control module and the contacts. It is contemplated that other types of communication between the control module and the sensor can be employed. For example, the control module and the water flow sensor can communicate wirelessly with the addition of appropriate transmitter and receiver circuitry.

(35) The foregoing detailed description is given primarily for clearness of understanding and no unnecessary limitations are to be understood therefrom, for modification will become obvious to those skilled in the art upon reading this disclosure and may be made upon departing from the spirit of the invention and scope of the appended claims. Accordingly, this invention is not intended to be limited by the specific exemplifications presented herein above. Rather, what is intended to be covered is within the spirit and scope of the appended claims.
