TECHNICAL FIELDEmbodiments of invention relate to plumbing assemblies and in particular plumbing siphons used in conjunction with drain/waste plumbing pipes for different sanitary ware.
BACKGROUNDThe term sanitary ware as used herein the specification and claims defines any such devices relating to or used in the disposal, especially of waterborne waste, such as, sinks, urine bowls and the like.
Siphons are fitted onto sanitary ware in order to prevent the egress of foul sewer gases and bad odor into washrooms, kitchens etc. A further purpose of siphons is to serve as a trap for articles accidentally dropped into the sanitary ware, so as to allow their collection. Those are often referred to as siphon traps.
Owing to its nature, a plumbing siphon is typically mounted below the sanitary ware, thus consuming space and being un-pleasing to the eye. Often such plumbing siphon are thus concealed within a service cabinet or by a concealment built around the piping.
A wide variety of prior art plumbing siphons are known in the art sharing the general concept of a structure having a flow path formed with an inlet connectable to the sanitary ware and an outlet connectable to a sewage main, with an intermediate liquid holding section.
SUMMARYThe disclosed subject matter is concerned with a plumbing siphon for a sanitary ware, said plumbing siphon comprising a generally S-like shaped tube having an inlet segment formed with an inlet end coupleable to the sanitary ware, an outlet segment formed with an outlet end coupleable to a sewage main, and an intermediate trap section; said inlet segment and outlet segment extend substantially parallel to one another.
According to another aspect of the disclosed subject matter there is disclosed a plumbing system extending from a sanitary ware mounted on a support wall, said system comprising a plumbing siphon formed as a generally S-like shaped tube having an inlet segment formed with an inlet end coupleable to the sanitary ware, an outlet segment formed with an outlet end coupleable to a sewage main, and an intermediate trap section; said inlet segment and outlet segment extend substantially parallel to one another.

- the strainer section comprises a removable strainer member accessible through an extension pipe section with the service opening extending substantially upwards. According to one particular design, the extension pipe section is substantially vertical, extending coplanar and parallel to the inlet segment and outlet segment;
- 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.
According to yet another aspect of the disclosed subject matter there is disclosed a fluid propelling unit for a plumbing siphon for use with a sanitary ware, comprising an inlet segment formed with an inlet end coupleable to the sanitary ware, an outlet segment formed with an outlet end coupleable to a sewage main, and an intermediate trap section; the fluid propelling element comprising a manually operated volumetric pump unit coupleable to the plumbing siphon for increase/decrease of the plumbing siphon volume.
Any one or more of the following features and designs may be incorporated in a fluid propelling unit according to the disclosed subject matter:
-
- the volumetric pump unit may be detachable attachable to the trap section of the plumbing siphon. Alternatively, the fluid propelling unit is integrated with a plumbing siphon of the disclosed subject matter.

In order to understand embodiments of the invention and to see how it may be carried out in practice, embodiments will now be described, by way of non-limiting examples only, with reference to the accompanying drawings, in which:
Turning first to the example illustrated in
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 parallel 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

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 (
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
Turning now to
The siphon 700 comprises an inlet segment 782 (
The siphon 700 forms a continuous member, which further comprises a strainer section 793 extending outwardly from the intermediate segment 784 and has a longitudinal axis AS (
The strainer section 793 is fitted with a threaded opening 795 for sealing by a screw-cap 797 (
The grasping portion 802 is shaped as a handle allowing easy removal of the strainer 801 out of the strainer section 793. At the assembled position (
The basket-like trap portion 804 may be perforated, slotted or a mesh of any desired density, ranging between a fine mesh up to a grid of only several obstructing elements.
The basket-like trap portion 804 comprises a base 807 and a side wall 808 surrounding the base 807 (
As best seen in
The grasping portion 802 of the removable strainer element 801 extends along the strainer section 793 towards the threaded opening 795, and slightly projects therefrom (
The arrangement is such that liquid flowing into the siphon 700 through inlet segment 782 passes through the basket-like trap portion 804 such that particles/dirt/hair are trapped thereby. The removable strainer 801 then can be easily removed from the strainer section 793 through the opening 795, cleaned and returned.
It is noted that since the strainer section 793 is inclined with respect to the intermediate segment 784 and the opening 795 is located above and spaced from the trap portion 788 of the siphon 700, liquid does not spill from the siphon upon opening cap 797.
Turning now to
The siphon 900 also differs from siphon 700 in that the strainer section 993 forms a continuous member with the trap portion 998.
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
