U-shaped trap section 28 comprises two substantially parallely extendingtube segments 30A, extending to theoutlet segment 22 via an inverted U-segment 32, and 30B extending towards theinlet segment 16 via aninclined segment 34. - As can be seen in the drawings, a longitudinal axis Ain of
inlet segment 16 extends parallel to a longitudinal axis Aout of theoutlet segment 22. Furthermore, as can be noticed in particular inFIG. 1A , the S-like shape pipe of the plumbing siphon 10 is co-planar and as will be explained hereinafter with reference toFIGS. 5A and 5B , facilitates that the system be mounted in a wall-flush configuration, thus consuming minimal space under the sanitary ware and in an eye-pleasing manner. - Turning now to the embodiment disclosed in
FIG. 2 , there is illustrated a plumbing siphon 40 being substantially similar to the example disclosed inFIGS. 1A and 1B however wherein theoutlet segment 44 extends substantially vertical, with its longitudinal axis Ain extending substantially parallel to the longitudinal axis Aout of theoutlet segment 46, with the provision of a laterally extendinginlet end 48, fitted with a threadedcoupling 50, for connection to a sanitary ware coupling segment collectively designated 52. Other design features of the plumbing siphon 40 are substantially similar with those disclosed in connection with the previous example. - The plumbing siphon illustrated in the example of
FIG. 3 resembles the embodiment ofFIGS. 1A and 1B however with the distinction of the longitudinal axis Ain of theinlet segment 64 extends coaxial with the outlet longitudinal axis Aout of theoutlet segment 68. Likewise, in the particular example ofFIG. 3 , thetrap section 70 comprises twoextension arms - The arrangement of the plumbing siphon 60 disclosed in
FIG. 3 provides substantially easy mounting and coupling to respective pipe segments of the plumbing system, namely the sanitaryware coupling segment 76 and sewage main (not shown) whereby the number of plumbing coupler elements—“records” may be reduced. For that purpose, it may be advantageous that the thread at theinlet end 65 and the thread at theoutlet end 69 be in opposite directions. - Turning now to
FIGS. 4A and 4B there is illustrated a modification of the plumbing siphon 60 illustrated inFIG. 3 . In this example, the plumbing siphon generally designated 80 has substantially the same shape and principal configuration as disclosed inFIG. 3 , namely wherein the longitudinal axis Ain of theinlet segment 82 extends coaxially with the longitudinal axis Aout of theoutlet segment 86, with the entire structure of the plumbing siphon 80 extending co-planar, i.e. theintermediate trap section 88 is formed with tworespective arm sections - However, the example of
FIGS. 4A and 4B differentiates from the previous embodiment in that it comprises anauxiliary inlet port 90 extending above theintermediate trap section 88. Such an auxiliary inlet port may be used for coupling to the plumbing siphon a variety of inlet piping connected for example to a dishwasher, laundry machine, side sink, and the like. Further appreciated the auxiliary inlet port may be fitted at other locations of the plumbing siphon, such as for example at the outlet segment, or along theinclined segment 94 extending below theinlet segment 82 and above thetrap section 88. - Furthermore, in the example of
FIGS. 4A and 4B , theintermediate trap section 88 is fitted with atrap outlet port 96 sealable by aremovable cover 98, typically screw coupled to the trap section. Thetrap outlet 96 is useful for maintenance of the system namely, cleaning and opening blocks, as well as the collecting of articles which may have accidentally dropped into the sanitary ware, such as rings, coins, and the like, which items will not flow into the sewage main but will rather collect and remain within thetrap section 88. -
FIGS. 5A and 5B illustrate a plumbing system in accordance with the disclosed subject matter generally designated 100 wherein the sanitary ware is wall-mountedsink 102 mounted such that itsrear end 104 extends parallel to a supportingwall 106. The system further comprises a wall mountedplumbing cabinet 107 with a hot/cold watermain supply 110, a plumbing siphon 116 in accordance with the present disclosed subject matter which is coupled at itsinlet end 120, via a sanitaryware coupling segment 124 to thesink 102 and having itsoutlet segment 128 coupled to the sewage main (illustrated by dashed lines at 130). - It is noticed that the plumbing siphon 116 in accordance with the illustrated example is fitted with an
auxiliary inlet port 134 coupled by aflexible pipe 136 to a dishwasher (not shown) and is further provided with a lateral sealabletrap outlet port 140 serving also as a fluid propelling unit as will be discussed hereinafter. - It is seen that the
plumbing assembly 100 is such that the plumbing siphon 116 extends substantially parallel to thesupport wall 106 and concealed within aplumbing cabinet 107, such that a utility cupboard (illustrated inFIG. 5B by dashed lines designated 109) has substantially no plumbing elements extending therethrough. Likewise, at the absence of such a cabinet, theplumbing box 107 may typically be concealed by an appropriate decorative cover (not seen). - In
FIGS. 6A and 6B there is illustrated a fluid propelling unit in accordance with the disclosed subject matter. In the illustrated example, a plumbing siphon 160 is illustrated (only partially inFIG. 6B ) said plumbing siphon being of same construction as disclosed in connection withFIGS. 4A and 4B . The plumbing siphon 160 comprises aninlet segment 164 and acoaxial outlet segment 166 with an intermediate trap-section 170 being a substantially U-like shaped piping fitted at its lowermost end with atrap outlet port 172. - The
outlet trap 172 comprises a downwardly extended threadedneck 174 fitted at its lower end with apipe section 178 securely attached to a bellows-pipeflexible pipe 182 the latter illustrated inFIG. 6B at its retracted position. A free end of thebellows pipe 182 is fitted with a stopper plug 186 (FIG. 6B ) screw coupled to the free end or press fitted therein. Acover 190 is provided and is formed with aninternal threading 192 fitted for screw coupling over the threadedneck portion 174 and for receiving theentire bellows pipe 182 with itsrespective stopper 186 at the fully contracted position as illustrated inFIG. 6A . The arrangement is such that when it is now required to service the plumbing siphon 160, e.g. for cleaning same, draining a blockage, removing any items which may have been trapped within thetrap section 170, thecover 190 is opened and removed, allowing access to thestopper 186 as well as to extending of thebellows pipe 182, in the position of 6B. - As further illustrated in
FIG. 6C , the length of thebellows pipe 182 may be such so as to facilitate directing thefree end 183 of thebellows pipe 182 towards a collecting reservoir e.g. abucket 185 or the like, to avoid spillage of waterborne waste. - It is noticed that removal of the
cover 190 and gripping at thestopper 186 to displace thebellows tube 182 into its retracted position (FIG. 6B ) and further back and forth such displacement between the retracted position (FIG. 6B ) and the fully contracted position (FIG. 6A ) along arrowedline 196 thus serves as a fluid propelling unit, namely a volumetric pump, which may be useful to overcome clogs which may occur at the plumbing siphon 160 or along the sanitaryware coupling segment 199 or in any segments extending between the plumbing siphon 160 and the sewage main (not shown). - It is appreciated that at the fully contracted position of the fluid propelling system (
FIG. 6A ) the bellows of thebellows pipe 182 are fully contracted namely extending flush against one another in a tight manner owing to theclosing cover 190, ensuring that any liquid waste or other water borne waste does not accumulate therebetween, for sanitary reasons. - Facilitating displacement of the fluid propelling unit, namely bellows
pipe 182 between its fully contracted position and its fully extracted position, alongarrow 196, may be by means ofappropriate handle 193 of stopper 186 (FIG. 6B ). - Turning now to
FIG. 7 , there is illustrated a plumbing siphon in accordance with yet a different example, generally designated 212, the plumbing siphon being substantially similar to the example discussed in connection withFIGS. 1A and 1B to which the reader is directed. However, the plumbing siphon 212 is fitted at itstrap section 214 with atrap outlet port 216 fitted with afluid propelling unit 220 in the form of a push-pipe volumetric pump of the type fitted with a flexible diaphragm (not seen) and a push-knob 226 designed for deforming said diaphragm between a detract position in which it reduces the internal volume of the system and a spontaneously projecting position as illustrated inFIG. 7 wherein the volume of the system increases, that being facilitated by means of an internal biasing element e.g. a coiled spring and the like. Thus, in use, a securing cap (not shown) is unscrewed from the threadedsupport neck 231, allowing thepush button 226 to spontaneously project into the position ofFIG. 7 . Pressing the knob inwards and releasing it, and further repeating this action several times will cause fluid propelling within the system, thus overcoming any blocks which may occur therein. - With further attention now being made to
FIGS. 8A to 8F there is illustrated a plumbing siphon system in accordance with yet an example of a disclosed subject matter, generally designated 250 wherein the plumbing siphon is similar to that disclosed in connection with the example illustrated inFIGS. 4A and 4B . In this example, the plumbing siphon has a longitudinal axis Ain of theinlet segment 254 extending coaxially with the longitudinal axis Aout of theoutlet segment 256, with theintermediate trap section 258 extending co-planar with the inlet segment and the outlet segment, such that its tworespective arms auxiliary inlet 266 and atrap outlet port 268, with an outlet section 270 (FIG. 8B ) extending downwards and formed with anexternal thread 272. - Screw coupled on the
outlet 270 there is a bellows-type pipe 280 deployable between a contracted position (FIGS. 8A to 8C ) and a retracted position (FIGS. 8D to 8F ). - As can be seen with further detail in
FIG. 8F , theoutlet pipe 280 is fitted at its inlet end with a threading 285 for screw coupling to threading 272 of the trap outlet, and at its opposite end, namely theoutlet end 287 is formed with athread 289 for engagement with a sealingplug 290. Thepipe 280 is a flexible bellows-pipe and is deployable between its normal contracted position (FIGS. 8A-8C ) and its extended position (FIGS. 8D-8F ) wherein it can be easily deflected for various purposes, for example to drain water borne waste directly into a collecting vessel e.g. bucket, or to collect any items which may have accidentally dropped through sanitary ware (not shown) and trapped within thetrap section 258. It is appreciated that thepipe 280 may be easily removed from the plumbing siphon for treatment of the system, e.g. cleaning and the like. Likewise, theflexible tube 280 may be replaced by other types of tubes namely any flexible pipe not necessarily a bellows-type pipe. - Turning now to
FIGS. 9A and 9B there are illustrated siphon systems in accordance with different examples of the disclosed subject matter, wherein the plumbing siphons are pivotally secured and rotatable about the longitudinal axis. - It is thus appreciated that the plumbing siphons disclosed in
FIGS. 9A and 9B are of the type disclosed for example in connection with examples ofFIGS. 4 and 8 , namely wherein the inlet segment and the outlet segment are coaxial about a longitudinal axis thereof, typically vertically extending whereby the siphon is rotatable thereabout as will be discussed hereinafter. - In
FIG. 9A the siphon system generally designated 300 comprises a plumbing siphon 304, of the type disclosed inFIG. 8A , wherein itsinlet segment 306 is coupled via a coupling section 310 to the sanitary ware which in the present example issink 314. Theoutlet segment 318 is coupled to the sewage main 320, wherein the coupling of both theinlet segments 306 andoutlet segments 320 coaxially extend and are pivotally coupled to the respective couplings, as illustrated byarrowed lines - In the present example, the siphon 304 is fitted at its trapped
segment 330 with aflexible drain pipe 334, for example as disclosed in connection with the embodiment ofFIG. 8 . - In the normal course of operation, the siphon assembly is in the position as illustrated by solid lines, namely received within the
cabinet 340. However, when it is desired to service the siphonsystem 300, the plumbing siphon 304 is pivotally rotated in direction ofarrow 344, about 180°, whereby the outlet may now extend over a drainingbucket 348 which by means of theretractable drain pipe 334 may now be drained. The second position is illustrated by dashed lines. - Turning now
FIG. 9B there is illustrated a different example of a rotatable plumbing siphon wherein the plumbing siphon is of the type disclosed in connection withFIGS. 4 and 8 whilst the installation thereof is of the type disclosed inFIGS. 5A and 5B , namely an inlet wall mounting. The siphon of this example is mounted such that itsinlet segment 410 and itsoutlet segment 412 are coaxially mounted about a substantially vertical axis wherein theinlet segment 410 is coupled through acoupling segment 416 to the sanitary ware, namely sink 418 whilst theoutlet segment 412 is coupled to the sewage main 420. Both couplings of theinlet segment 410 andoutlet segment 412 are pivotal couplings facilitating pivotal displacement of the siphonsystem 400 between a normal, operative position as illustrated by solid lines, wherein the plumbing siphon extends within an opening in thewall 423 and substantially parallel to the wall. However, when it is now desired to drain the system or services, the plumbing siphon is rotated about 90° degrees in direction ofarrow 425, where the drainingpipe 426 may now be extracted for draining into a collectingvessel e.g. bucket 428. - Turning now to
FIGS. 10A to 10C there is illustrated a siphon according to another example of the disclosed subject matter, generally designated 500, having design features similar to those disclosed in connection with previous examples, e.g. in connection withFIGS. 3 and 4 . For sake of clarity, like reference numbers have been designated as inFIG. 4 , however shifted by 500. - The siphon 500 is further provided intermediate the
inlet segment 582 and thetrap section 588 with astrainer section 593 in the form of a substantially upright extending tube section, with its axis Astr coplanar and parallel with the longitudinal axis Ain of theinlet segment 582 and with the longitudinal axis Aout of theoutlet segment 586. - The
strainer section 593 extends between the inclined segment 594 (extending below the inlet segment 582) and above thevertical section 584B of thetrap section 588, thus being in flow communication therebetween, wherein any material flowing in direction from theinlet 582 towards thetrap 588 flows through saidstrainer section 593. Thestrainer section 593 is fitted with a threadedopening 595 for sealing by a screw-cap 597. it is noted that theopening 595 extends above a lowermost level of theinclined segment 594, i.e. above highest possible liquid level of the trap section, whereby liquid does not spill from the siphon uponopening cap 597. - Received within the siphon, namely at the straight,
vertical section 584B of thetrap section 588, there is a cup-like strainer element 601 fitted with a withdrawal ring which at the assembled position (FIG. 10C ) extends adjacent theopening 595 and is easily accessible therethrough for removal of the strainer. The strainer may be a mesh of any desired density, ranging between a fine mesh up to a grid of only several obstructing elements. Thestrainer element 601 is received within thetrap section 588 such that at least itstop section 607 is snugly received within a correspondinginside wall section 609 of thestrainer section 593, whereby thestrainer element 601 is fixedly received within the siphon and substantially all liquids flowing through the device flow through the strainer element. Likewise, where thestrainer element 601 slightly tapers (as see best inFIG. 10C ) it is easily removed and returned back in place. - The arrangement is such that liquid flowing into the siphon through
inlet 582 passes through thestrainer section 593 such that particles/dirt/hair are trapped by the mesh and are easily removable by opening thecap 597, removing thestrainer element 601, cleaning it and returning it. - The example of
FIGS. 10A and 10B exemplifies and arrangement wherein theauxiliary inlet port 590′ is an integral part of anelbow coupler element 548. However, the auxiliary inlet port may just as well be articulated as part of the cap 597 (not shown) or as an extension from thevertical section 584B. - It is further appreciated that the strainer may be articulated or integrally manufactured with the removable cap (e.g. by a flexible or rigid connecting rod, such that upon withdrawal of the cap the strainer is removed therewith.
- Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations, and modifications can be made without departing from the scope of the invention, Mutatis Mutandis
