Abstract
A dry trap valve, such as usable in a non-flushing urinal and other drains, is employed to transport a fluid, such as urine or other wastewater to a sewer line for receipt and disposal of the wastewater. The dry trap valve includes a holder (e.g., a band holder) having an entry for receipt of the wastewater, a drain for disposal of the wastewater, a passageway (e.g., dent, depression or bypass) for conducting the wastewater from the entry to the drain, and an element e.g., a sealing band) for sealingly covering the passageway. The sealing band includes a hinged portion adjacent the lower end of the dent and is disposed to articulate upon flow of the wastewater from the dent and to permit the wastewater to flow to the drain and to close in the absence of the wastewater flow. Gases from the sewer line also press upon the sealing band in the absence of wastewater flow to further seal the dent. Thus, the memory of the elastomeric material is not essential but, rather, the forces of gravity and the force of the sewer gas keeps the passage closed to the sewer gases that would otherwise back up through the valve.
Description
- This application claims benefit of
provisional application 61/336,300 filed 20 Jan. 2010. - Not Applicable
- Not Applicable
- The present invention relates to a flow trap, such as a cartridge used in non-flushing urinals, and having an odor preventing mechanism and, in particular, to a improved trap that uses a dry trap valve that can be used without water or sealant, thereby resulting in improved flow trap life and usability, and eliminating the need for water to flush the trap.
- In any sort of plumbing trap, it is necessary to provide for the one-way flow of waste water into and through the trap to a drain line, while blocking sewer gas and other unpleasant odors from backing up from the drain line, through the trap and into the room. In traditional urinals, this is accomplished by an “S” shaped trap (or similar device) that has a curve that is flushed with fresh water after each use, and with fresh water providing an odor seal.
- Non-flushing traps are advantageous where water is scarce or expensive, or when water conservation is desired. Prior art units include those described in U.S. Pat. No. 6,053,197, in which a lighter than water sealant forms the odor barrier, and wherein the sealant remains in the trap.
- Other prior art traps have employed one-way flapper style valves to form the odor barrier, such as is described in UK Published Application No. 2,296,309. Such flapper valves rely upon opposing pieces of elastomeric material having memory so that the tips are normally in a closed position. Such valves typically consist of a circular entry area which flattens out to two generally flattened abutting sides forming the exit area, in which shape memory urges the two sides against each other to seal out gasses and odors coming back up through the line. The force of the urine overcomes the elastomeric qualities and opens the two flattened parts of the exit side and allows wastewater to flow into the trap. The combination of the shape of the flattened exit, and the memory qualities of the materials used, urge the two sides against each other to prevent malodorous gasses from escaping into the room.
- Unfortunately, after repeated use of such prior art flapper-style valves, the elastomer loses its shape memory, and may remain open and allow malodorous gas to back up through the trap into the room. Also, prior art flappers can dry out and remain open.
- These and other problems are successfully addressed and overcome by the present invention, in which a dry trap valve, such as usable in a non-flushing urinal and other drains, is employed to transport a fluid, such as urine or other wastewater to a sewer line for receipt and disposal of the wastewater. The dry trap valve includes a holder (e.g., a band holder) having an entry for receipt of the wastewater, a drain for disposal of the wastewater, a passageway (e.g., dent, depression or bypass) for conducting the wastewater from the entry to the drain, and an element e.g., a sealing band) for sealingly covering the passageway. The sealing band includes a hinged portion adjacent the lower end of the dent and is disposed to articulate upon flow of the wastewater from the dent and to permit the wastewater to flow to the drain and to close in the absence of the wastewater flow. Gases from the sewer line also press upon the sealing band in the absence of wastewater flow to further seal the dent.
- Attendant advantages are that the memory of the elastomeric material is not essential but, rather, the forces of gravity and the force of the gas keeps the passage closed to sewer gasses that would otherwise back up through the valve.
- Other aims and advantages, as well as a more complete understanding of the present invention, will appear from the following explanation of an exemplary embodiment and the accompanying drawings thereof.

- Referring to
FIGS. 1-7 , a trap orcartridge 20 for a non-flushing urinal is shown as placed in a urinal (seeFIGS. 2 and 3 ) as represented by portions thereof and designated byindicium 21, such as exemplified in U.S. Pat. No. 6,959,723 (specificallyFIG. 15 thereof), whose contents are incorporated herein as if set forth in haec verba.Trap 20 comprises atop portion 22, which is disposed to support adry valve 24 having an entry tube ordry valve entry 32, and abase portion 26.Top portion 22 includes acover 28 which, in turn, includes an entry opening 30 for receipt of urine or other wastewater. An O-ring 23 within an annular slot incover 28 provides a seal with urinal 21. As best shown inFIG. 3 , a downwardly extending lip orbrim 31 is formed on the underside ofcover 28 andsurrounds opening 30, thereby to enabledry valve 24 to be secured toentry tube 32. Wastewater is directed bycover 28 to opening 30 where it entersentry tube 32 ofdry valve 24. - As depicted in
FIGS. 2 , 3, 5-7 and 19, abarrier 70 separates the cartridge into two compartments, a fluid inlet compartment and a fluid outlet compartment, for example as illustrated and described in U.S. Pat. No. 7,575,022 whose contents are incorporated herein as if set forth in haec verba. The fluid outlet compartment terminates in a drain 40 (seeFIGS. 2 , 3-5 and 7), from whence it passes to a sewer line (as symbolized by enclosure 41) or similar outlet.Barrier 70 terminates in atoothed comb 72 and, when top portion is coupled together with base orbottom portion 26, slips into guidingslots 74 thereof. The base portion is further provided withteeth 76 which cooperate with the teeth ofcomb 72 to strain or otherwise catch debris and the like. - Referring also to
FIGS. 8-15 ,dry valve 24 comprises a band holder orrigid portion 34 formed generally as a planar ramp having afront side 34A and aback side 34B (shown in isolation inFIGS. 10-13 ), a clamp 38 (shown in isolation inFIGS. 14 and 15 ) and a sealing band or movable portion 50 (shown in isolation inFIGS. 16-18 ).Entry tube 32 is on an upper portion ofband holder 34 and is adapted to receive wastewater from opening 30 incover 28. A dent, depression or bypass 36 (seeFIGS. 3 , 5, 10 and 11) is formed inband holder 34 and extends or protrudes from itsback side 34B. Dent 36 includes lower andupper ends lower end 36A is distanced fromentry 32 andupper end 36B is positioned adjacent toentry 32. As can be best seen inFIGS. 3 , 5 and 10, a fluid passage for the wastewater passes fromentry tube 32 todent 36, along aflattened portion 39 ofband holder 34, and intobase 26 oftrap 20, where it can flow out of the trap or cartridge through drain 40 (seeFIGS. 2 , 3-5 and 7), from whence it passes tosewer line 41 or similar outlet. -
Band holder 34 andclamp 38 can be made of any number of materials, such as plastic, metal, sintered ceramic, or any material that can be molded into the desired shape and is reasonably rugged. It has been found that acrylonitrile butadiene styrene (ABS) or polypropylene (PP) work well in this application. -
Sealing band 50 can be made of any flexible material like rubber, silicon rubber or any thermoplastic elastomer. A synthetic rubber sheet with a thickness in the range of 0.2 mm-0.4 mm has been found to work well. - Although
band holder 34 can be attached totrap 20 in any number of ways, it has been found that glueing, compression fit, snap fit and ultrasonic welding all yield satisfactory results. The attachment preferably is such that flattenedportion 39 forms a downward slope at an angle of about 10° to 50° from the vertical and, in a preferred embodiment, is about 30° (as generally seen inFIGS. 11 and 12 ); however, it is to be understood that, at least as presently formulated,dry valve 24 is capable of functioning between the horizontal to close to the vertical, that is, within the angle ranges of 0° to less than 90°. - Referring to
FIGS. 9-13 ,band holder 34 has two upper slots, to with, rightupper slot 42A and leftupper slot 42B, and two lower slots, rightlower slot 44A and leftlower slot 44B. As further shown inFIGS. 14 and 15 ,clamp 38 has corresponding prongs, namely rightupper prong 46A, leftupper prong 46B, leftlower prong 48B and rightlower prong 48A. As also depicted particularly inFIGS. 8 and 9 , the respective prongs ofclamp 38 fit and snap into the slots inband holder 34 to provide a clamping arrangement, viz.,prong 46A intoslot 42A,prong 46B intoslot 42B,prong 48A intoslot 44A, andprong 46B intoslot 44B. - Referring to
FIGS. 16-18 , sealingband 50 has anupper portion 56, alower portion 58, aright projection wing 54A and aleft projection wing 54B.Upper portion 56 is positioned generally atop dentupper end 36B andlower portion 58 is positioned generally below dentlower end 36A. As more fully discussed below,projection wings FIGS. 17 and 18 , generally along dashedfold lines 55, as shown inFIG. 16 , which also illustrates how the sealing band projection bands would be bent or folded over when the sealing band is secured to bandholder 34. - With reference to
FIGS. 8 and 9 , sealingband 50 is placed ontofront side 34A ofband holder 34, such that it completely blocksentry tube 32, that is, sealing bandupper portion 56 extends from at least as high asupper slots lower portion 58 at least coversdent 36.Projection wings band holder 34, and are folded back aroundband holder 34, and secured thereto at itsback side 34B preferably by affixingmechanisms 35, or by any other mechanical implementation or bonding agent that ensures a complete securing between the sealing band and the band holder so as to hold sealingband 50 in position. As illustrated herein, affixingmechanism 35 comprises arrow-headed punch-throughs extending outwardly from holder backside 34A for piercing throughprojection wings band 50. Other fixation/anchorage technology known in the art may be used, particularly when overmolding (e.g., multiple molding techniques) technology is utilized. - As shown in
FIGS. 8 and 9 ,lower portion 58 of sealingband 50 is capable of or otherwise disposed to flip or hinge upwards along line A-A′ in response to urine flow. Line A-A′ is located just beneathprojection wings band 50, such that most ofdent 36 is always covered by sealingband 50 even when wastewater is flowing, and most of the portion of the sealing band that does flip upwards, from line A-A′ to the lower end of theband 50, lays beyond the lower end ofdent 36, utilizing sealingband 50 as a hinge. This organization results in an articulated or hinged movement that allowsvalve 24 to open and to close. The wastewater flow lifts the sealing band up to open and, after the liquid flow, gravity closes the opening again. - Sealing
band 50 is coupled toband holder 34 to coverdent 36. In the preferred embodiment of the present invention, the sealing band is held in place by wrapping bothwing portions sides wing portions clamp 38 over sealingband 50 to clamp it to bandholder 34. While a frictional engagement is employable, the preferred clamping is to make use of a press fitting of rightupper prong 46A into rightupper slot 42A, leftupper prong 46B into leftupper slot 42B, rightlower prong 48A into rightlower slot 44A, and leftlower prong 48B into leftlower slot 44B. -
Clamp 38 also has a pair of curved flanges,right flange 52A and leftflange 52B. The flanges are spaced far enough apart so as not to coverdent 36, for urging or pressing sealingband 50 againstband holder 34. - In a preferred embodiment, such as depicted in
FIGS. 8 and 9 (see alsoFIGS. 10-13 ), sealingband projection wings lower end 36A ofdent 36, whileupper portion 56 of sealingband 50 extends beyondupper end 36B ofdent 36, which is fully covered by sealingband 50 in combination with and compressed byclamp 38 to form a seal. - The dimensions of the above parts are generally based upon the size of the urinal trap. The size and shape (curvature or otherwise) of
dent 36 can be adjusted depending upon the anticipated liquid flow. - In operation, between uses of
trap 20, sealingband 50 is held in place, blockingdent 36 andentry tube 32, in large part by the force of gravity, due to the angle of flattenedportion 39. The primary purpose of the elastomeric qualities of sealingband 50 is to use it as a hinge. Because sealingband 50 is lying flat and sealed againstdent 36 andentry tube 32, sewer gasses and unpleasant odors fromsewer line 41 are blocked from entering the room. It has been found that pressure from the sewer gasses fromsewer line 41 are able to urge sealingband 50 more firmly againstdent 36 andentry tube 32. - When the urinal is utilized, wastewater will be directed to entry opening 30 of the trap, and therethrough to
entry tube 32 ofdry valve 24. The force of the wastewater throughentry tube 32 anddent 36 provides adequate pressure to overcome the force of gravity that is holding sealingband 50 in place, and urges the sealing band upwards, allowing the wastewater to flow past, along flattenedportion 39, and to drain 40. When the flow of wastewater ceases, gravity again urges sealingband 50 downward againstdent 36 andentry tube 32, again providing a seal against gas and odor. Thus, wastewater or other fluids are transported from opening 30, throughdrain 40 and tosewer line 41. - As depicted in
FIGS. 5 , 19 and 20,cartridge 20 can be inserted or removed, such as by being screwed into or removed from a urinal by use of a key 62.Key 62 includes abent tip 64 and a stop angledpart 66 at one end and ahandle 68 at its other end.Bent tip 64 is disposed to fit within entry opening 30 oftop portion 22 and to be canted therein.Part 66 contacts cover 28 to aid in the attachment oftip 64 withinopening 30. - Although the present invention has been described as used in a trap for a non-flushing urinal and as indicated above, it can be employed in any situation requiring an odor blocking drain trap, such as shower, bath, sink, floor and other drains. Thus, although its operation was described above with reference to a non-flushing urinal, it should be kept in mind that this is only for ease of example, and that many other such applications are possible.
