Filed Jan. 25, 1961, Ser. No. 84,861 2 Claims. (Cl. 137-593) This invention relates to flood control apparatus, and
' in particular to a portable flood control apparatus for preventing basement flooding due to sewage backing up through a sewer, which device can be removably positioned with its lower end in register with the drain opening, permitting the water from the sewer to rise within the device until it reaches a level corresponding to the level of water in the main sewer outside the basement.
One class of device designed to prevent sewer water from backing up through a basement drain incorporates a valve or plug member positioned within the drain pipe beneath the basement floor level. The installation of most of these devices requires extensive modification of the drain to accommodate the valve or plug, and consequently a large expenditure on the part of the building owner. Furthermore, these devices contain moving parts which are subject to wear and/ or the possibility that they may not function properlyat a crucial time.
Another class of flood control device in general use incorporates an electrically driven pump or the like which pumps the water entering the basement back outside the building. Although these devices function satisfactorily under most conditions, each is limited by the capacity of the mechanism to dispose of the water. If the water is backing up through the sewer into the basement at a rate in excess of the capacity of the device to pump it out, some flooding will obviously result. In addition, these electrically operated devices are only as reliable as the source of electricity. If the electric supply fails, the device is of no use whatsoever.
The instant invention presents a device superior to those mentioned above in a number of ways. The device is completely portable, and may be easily positioned for use in event of flooding conditions, then stored away conveniently when the danger has passed. Further, it contains no moving parts subject to wear or malfunction, and does not require for its operation any connection to a source of power supply.
An object of the present invention is the provision of a completely portable sewer flood control apparatus which may be removably positioned over a sewer opening, allowing backup water from the sewer to rise within the device until the water reaches a level therein corresponding to the level of water in the main sewer outside the building, and preventing any backup water from escaping from the drain and flooding over the surrounding basement floor.
A further object is the provision of such a device which contains no moving parts subject to wear or malfunction, and which functions independently of any external power supply.
Other objects, advantages and meritorious features will more fully appear from the following specification, claims and attached drawings wherein:
FIG. 1 is a longitudinal cross sectional view showing the apparatus of the invention positioned in register with a sewer drain in a basement floor;
FIG. 2 is a fragmentary cross sectional view similar to FIG. 1, showing the flood control apparatus positioned on a sloping basement floor;
FIG. 3 is a bottom view of the sealing mat for preventing water from a drain from seeping radially outwardly of the flood control apparatus;
FIG. 4 is a top view of the mat shown in FIG. 3;
FIG. 5 is a side view of a water closet showing an "ice embodiment of the invention positioned in register'with the bowl of the closet;
FIG. 6 is a plan view of the apparatus shown inFIG;
5; and
FIG. 7 is a partial cross sectional viewtaken along'liue.
7--7 of FIG. 6.
Referring now to the drawings, it can be seen that the portable sewer flood control device 20 consists of a sleevelike member 22 positioned on the basement floor 24 in register with a drain 26 which is connected to a sewer (not shown). Mounted on the lower peripheral edge 28' of sleeve 22 is a flexible, resilient sealing mat 30, having an aperture 32 therethrough corresponding in size to the drain 26 and in registry therewith. An upwardly extending flange 34 on mat 30 encircles the lower edge sealing mat 30 rests against the floor 24 and is held in sealing engagement therewith by the weight 36. Aswater from the sewer flows upwardly through drain 26, it is free to overflow the drain and rise within the sleeve 22, through the apertures 32 and 40 respectively, in mat 30 and weight 36. Weight 36 must be heavy enough to counter any buoyant effect from the water rising within the sleeve and still hold mat 30 in sealing contact with floor 24.
Sealing mat 30 may be made of any flexible, resilient material, but is preferably made of fairly soft, pliable rubber. The lower side 42 of mat 30 (most clearly shown in FIG. 3), engages the basement floor 24 and exhibits a plurality of continuous, concentric, ring'like projections 44, and also radially extending strips 46 These projections 44 and 46 are integral with the mat 30 and are preferably of semi-circular cross section, the curved surfaces engaging the basement floor 24.- The upper side 48 of mat 30 (shown most clearly in FIG. 4), upon which the weight 36 rests, exhibits a plurality of rows of resilient blocks 50, extending upwardly therefrom in spaced-apart relation. Each of the blocks 50 is so positioned on mat 30 as to lie betweenthe projections 44 and 46 on the lower side 42 of the mat 30.
It should be noted that the configuration of the projections 44 and 46, and the blocks 50 shown in FIGS. 3 and 4 may be modified to other forms not shown, but which will funtcion satisfactorily also. For instance, projections 44 and 46 might well be arranged on the bottom of mat 30 in criss-cross fashion.
To use the apparatus 20, the sleeve 22 is placed upright on the basement floor 24 with the aperture 32 of the sealing mat 30 in fluid conducting communication with drain 26. Thereafter the weight 36 is lowered within the sleeve 22 until it rests against the blocks 50 of mat 30. The downward force exerted by weight 36 against blocks 50 presses the projections 44 and 46 tightly against the floor 24, achieving a fluid-tight seal therebetween.
Referring to FIGS. 1 and 2, it will be noted that the bottom surface 52 of weight 36 is sloped or tapered. Thus whether the basement floor 24 is substantially flat as in FIG. 1, or slopes downwardly toward the drain 26 as in FIG. 2, the weight 36 will always rest on the innermost row of blocks 50, and exert suflicient force thereon to sealingly engage those projections 44 which are immediately adjacent the drain 26 with the floor 24.
Patented May 1, 196 2 Most basement floors are pitched toward the floor drain so that water on the floor will flow toward the drain. Were the surface of the weight 36 to have a bottom surface 52 which was flat, it is conceivable that the weight would not contact the row of blocks 50' and sewage backing up through the drain 26 would seep along the floor 24 and escape radially outwardly of the lower end 28 of the sleeve 22.
In FIGS. 5, 6 and 7 a device embodying the invention is shown adapted to be used in conjunction with a base ment water closet 54. If the water in the main sewer outside the building rises to a height above the height of the water closet bowl 56, sewage backing up through the sewer will overflow the upper rim 58 of the bowl 56 and flood the basement floor 60. To prevent such overflow a sleeve-like member 62 is provided, which is placed upon the bowl 56, with its lower flanged end 64 in contact with the upper rim 58 of bowl 56. A sealing ring 66 is interposed between the flange 64 and the rim 58 to provide a fluid-tight seal between the sleeve 62 and the bowl 56. The ring 66 may be sealingly secured to the lower side of flange 64, or may be a separate member, as shown in FIG. 7. The former is preferable, as it makes assembly of the apparatus on the bowl 56 easier.
The sealing ring 66 may be made of rubber or any other material having a resiliency which will assure a fluid tight seal between the sleeve 6-2 and the bowl 56, and which will be impervious to water. Sealing ring 66'may also be constructed with a configuration similar to that shown in FIGS. 3 and 4 and described in detail hereinabove, or may be a ring having smooth faces which engage flange 64 and rim 58.
It will be appreciated that means are necessary to hold sleeve 62 in position and to press ring 66 into fluid tight engagement with the rim 58. One simple and satisfactory way to accomplish this is the provision of a pair of substantially J-shaped members 68, which extend along the inner surface of sleeve 62. Plate-like members 70 are placed across the upper edge 72 of sleeve 62, and have clearance "holes 74 therethrough for insertion of the J-shaped members 68. The bight 76 of the J is positioned so as to grasp and embrace the inwardly projecting edge 78 of rim 58. The leg 89 of the J provided with a threaded length 82 at its upper end, is inserted through hole 74 in plate 76, and is threadedly engaged with a nut or the like 84. This is most clearly shown in FIG. 7. As nut 84 is tightened against plate 70, sleeve 62 and sealing ring 66 are urged downwardly against rim 58, assuring a fluid tight seal between the sleeve 62 and the bowl 56. Sewage backing up through water closet 54 will thereby rise in sleeve 62, preventing flooding of basement floor 60.
