  • DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS
  • Turning first to the example illustrated in FIGS. 1A and 1B there is disclosed a plumbing siphon generally designated 10, for use in conjunction with a sanitary system (of which only a sanitary ware coupling section 12 is illustrated).
  • The plumbing siphon 10 has a generally S-like shape in the form of a continuous pipe formed with an inlet segment 16 having a threaded inlet end 18 coupleable to the sanitary ware (in the present example by the extension segment 12 though other possibilities are available too, e.g. flexible piping, etc.).
  • At the lower, opposite end of the plumbing siphon 10 there is formed an outlet segment 22 formed with a threaded outlet 24, which in turn is coupleable to a sewage main (not shown). In between the inlet segment 16 and outlet segment 22 there is a trap section 28 which is substantially an uprightly extending U-like segment adapted to constantly hold liquid so as to prevent egress of foul sewage gases and bad odor from the outlet end towards the inlet and from there towards the washroom, kitchen, etc.
  • The U-shaped trap section 28 comprises two substantially parallely extending tube segments 30A, extending to the outlet segment 22 via an inverted U-segment 32, and 30B extending towards the inlet segment 16 via an inclined 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 the outlet segment 22. Furthermore, as can be noticed in particular in FIG. 1A, the S-like shape pipe of the plumbing siphon 10 is co-planar and as will be explained hereinafter with reference to FIGS. 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 in FIGS. 1A and 1B however wherein the outlet segment 44 extends substantially vertical, with its longitudinal axis Ain extending substantially parallel to the longitudinal axis Aout of the outlet segment 46, with the provision of a laterally extending inlet end 48, fitted with a threaded coupling 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 of FIGS. 1A and 1B however with the distinction of the longitudinal axis Ain of the inlet segment 64 extends coaxial with the outlet longitudinal axis Aout of the outlet segment 68. Likewise, in the particular example of FIG. 3, the trap section 70 comprises two extension arms 72A and 72B both extending parallel to one another and parallel to the longitudinal axis Ain and Aout, all extending co-planar.
  • 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 sanitary ware 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 the inlet end 65 and the thread at the outlet end 69 be in opposite directions.
  • Turning now to FIGS. 4A and 4B there is illustrated a modification of the plumbing siphon 60 illustrated in FIG. 3. In this example, the plumbing siphon generally designated 80 has substantially the same shape and principal configuration as disclosed in FIG. 3, namely wherein the longitudinal axis Ain of the inlet segment 82 extends coaxially with the longitudinal axis Aout of the outlet segment 86, with the entire structure of the plumbing siphon 80 extending co-planar, i.e. the intermediate trap section 88 is formed with two respective arm sections 84A and 84B extending co-planar and substantially with their longitudinal axes parallel to the longitudinal axes Ain and Aout.
  • However, the example of FIGS. 4A and 4B differentiates from the previous embodiment in that it comprises an auxiliary inlet port 90 extending above the intermediate 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 the inclined segment 94 extending below the inlet segment 82 and above the trap section 88.
  • Furthermore, in the example of FIGS. 4A and 4B, the intermediate trap section 88 is fitted with a trap outlet port 96 sealable by a removable cover 98, typically screw coupled to the trap section. The trap 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 the trap 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-mounted sink 102 mounted such that its rear end 104 extends parallel to a supporting wall 106. The system further comprises a wall mounted plumbing cabinet 107 with a hot/cold water main supply 110, a plumbing siphon 116 in accordance with the present disclosed subject matter which is coupled at its inlet end 120, via a sanitary ware coupling segment 124 to the sink 102 and having its outlet 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 a flexible pipe 136 to a dishwasher (not shown) and is further provided with a lateral sealable trap 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 the support wall 106 and concealed within a plumbing cabinet 107, such that a utility cupboard (illustrated in FIG. 5B by dashed lines designated 109) has substantially no plumbing elements extending therethrough. Likewise, at the absence of such a cabinet, the plumbing 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 in FIG. 6B) said plumbing siphon being of same construction as disclosed in connection with FIGS. 4A and 4B. The plumbing siphon 160 comprises an inlet segment 164 and a coaxial outlet segment 166 with an intermediate trap-section 170 being a substantially U-like shaped piping fitted at its lowermost end with a trap outlet port 172.
  • The outlet trap 172 comprises a downwardly extended threaded neck 174 fitted at its lower end with a pipe section 178 securely attached to a bellows-pipe flexible pipe 182 the latter illustrated in FIG. 6B at its retracted position. A free end of the bellows pipe 182 is fitted with a stopper plug 186 (FIG. 6B) screw coupled to the free end or press fitted therein. A cover 190 is provided and is formed with an internal threading 192 fitted for screw coupling over the threaded neck portion 174 and for receiving the entire bellows pipe 182 with its respective stopper 186 at the fully contracted position as illustrated in FIG. 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 the trap section 170, the cover 190 is opened and removed, allowing access to the stopper 186 as well as to extending of the bellows pipe 182, in the position of 6B.
  • As further illustrated in FIG. 6C, the length of the bellows pipe 182 may be such so as to facilitate directing the free end 183 of the bellows pipe 182 towards a collecting reservoir e.g. a bucket 185 or the like, to avoid spillage of waterborne waste.
  • It is noticed that removal of the cover 190 and gripping at the stopper 186 to displace the bellows 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 arrowed line 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 sanitary ware 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 the bellows pipe 182 are fully contracted namely extending flush against one another in a tight manner owing to the closing 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, along arrow 196, may be by means of appropriate 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 with FIGS. 1A and 1B to which the reader is directed. However, the plumbing siphon 212 is fitted at its trap section 214 with a trap outlet port 216 fitted with a fluid 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 in FIG. 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 threaded support neck 231, allowing the push button 226 to spontaneously project into the position of FIG. 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 in FIGS. 4A and 4B. In this example, the plumbing siphon has a longitudinal axis Ain of the inlet segment 254 extending coaxially with the longitudinal axis Aout of the outlet segment 256, with the intermediate trap section 258 extending co-planar with the inlet segment and the outlet segment, such that its two respective arms 260A and 260B extend co-planar and substantially with their longitudinal axes parallel to the longitudinal axes Ain and Aout. Also noted, the siphon is fitted with an auxiliary inlet 266 and a trap outlet port 268, with an outlet section 270 (FIG. 8B) extending downwards and formed with an external 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, the outlet 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 the outlet end 287 is formed with a thread 289 for engagement with a sealing plug 290. The pipe 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 the trap section 258. It is appreciated that the pipe 280 may be easily removed from the plumbing siphon for treatment of the system, e.g. cleaning and the like. Likewise, the flexible 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 of FIGS. 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 in FIG. 8A, wherein its inlet segment 306 is coupled via a coupling section 310 to the sanitary ware which in the present example is sink 314. The outlet segment 318 is coupled to the sewage main 320, wherein the coupling of both the inlet segments 306 and outlet segments 320 coaxially extend and are pivotally coupled to the respective couplings, as illustrated by arrowed lines 322 and 324, respectively.
  • In the present example, the siphon 304 is fitted at its trapped segment 330 with a flexible drain pipe 334, for example as disclosed in connection with the embodiment of FIG. 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 siphon system 300, the plumbing siphon 304 is pivotally rotated in direction of arrow 344, about 180°, whereby the outlet may now extend over a draining bucket 348 which by means of the retractable 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 with FIGS. 4 and 8 whilst the installation thereof is of the type disclosed in FIGS. 5A and 5B, namely an inlet wall mounting. The siphon of this example is mounted such that its inlet segment 410 and its outlet segment 412 are coaxially mounted about a substantially vertical axis wherein the inlet segment 410 is coupled through a coupling segment 416 to the sanitary ware, namely sink 418 whilst the outlet segment 412 is coupled to the sewage main 420. Both couplings of the inlet segment 410 and outlet segment 412 are pivotal couplings facilitating pivotal displacement of the siphon system 400 between a normal, operative position as illustrated by solid lines, wherein the plumbing siphon extends within an opening in the wall 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 of arrow 425, where the draining pipe 426 may now be extracted for draining into a collecting vessel 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 with FIGS. 3 and 4. For sake of clarity, like reference numbers have been designated as in FIG. 4, however shifted by 500.
  • The siphon 500 is further provided intermediate the inlet segment 582 and the trap section 588 with a strainer 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 the inlet segment 582 and with the longitudinal axis Aout of the outlet segment 586.
  • The strainer section 593 extends between the inclined segment 594 (extending below the inlet segment 582) and above the vertical section 584B of the trap section 588, thus being in flow communication therebetween, wherein any material flowing in direction from the inlet 582 towards the trap 588 flows through said strainer section 593. The strainer section 593 is fitted with a threaded opening 595 for sealing by a screw-cap 597. it is noted that the opening 595 extends above a lowermost level of the inclined segment 594, i.e. above highest possible liquid level of the trap section, whereby liquid does not spill from the siphon upon opening cap 597.
  • Received within the siphon, namely at the straight, vertical section 584B of the trap section 588, there is a cup-like strainer element 601 fitted with a withdrawal ring which at the assembled position (FIG. 10C) extends adjacent the opening 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. The strainer element 601 is received within the trap section 588 such that at least its top section 607 is snugly received within a corresponding inside wall section 609 of the strainer section 593, whereby the strainer element 601 is fixedly received within the siphon and substantially all liquids flowing through the device flow through the strainer element. Likewise, where the strainer element 601 slightly tapers (as see best in FIG. 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 the strainer section 593 such that particles/dirt/hair are trapped by the mesh and are easily removable by opening the cap 597, removing the strainer element 601, cleaning it and returning it.
  • The example of FIGS. 10A and 10B exemplifies and arrangement wherein the auxiliary inlet port 590′ is an integral part of an elbow 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 the vertical 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
