Definitions

  • This invention relates to a drain trap for sinks and the like and particularly an easy-clean, no-spill trap.
  • An object of the present invention is to provide an improvement to the foregoing traps such that the liquid in the pipes can be collected, without spillage, in the removable portion of the trap hereinafter referred to as a container, thereby resulting in a spill free clean out trap.
  • applicant has provided a trap wherein the container is provided with additional liquid free volume (above the normal water level therein when in use) to collect and hold the liquid in the conduits when the seal is broken between the container and cover therefor to which an inlet and outlet pipe is connected.
  • a spill free clean out type sink trap which, when mounted in situ and during normal operation, has liquid therein that extends upwardly into respective inflow and outflow conduits comprising:
  • a sink trap comprising a container 10 detachably and sealingly connected to a cover 20. Liquid inflow to the trap is via inlet conduit 30 and liquid outflow via outlet conduit 40.
  • the effective open end of the conduits 30 and 40 in container 10 are located a selected distance downwardly from the cover (i.e. the upper end of the container) providing a liquid free space 50 in the container thereabove during use of the trap.
  • the liquid 60 has a level designated 61 in the inlet conduit, a level designated 62 in the container and a level designated 63 in the outlet conduit.
  • the liquid free volume 50 in the container, above liquid level 62, is at least equal to and preferably greater than the volume of the portion of liquid 60 contained in the inlet and outlet conduits 30 and 40 so that when the seal between the container 10 and cover 20 is broken, the liquid in the conduits will flow into the volume 50 in the container. This results in collecting all of the liquid in the container with no spillage occurring when removing the container 10 to clean out the trap.
  • the container 10 is detachably connected to the cover 20 by a threaded ring nut 21 and for sealing purposes there is provided a gasket 22 between the container and the cover.
  • the cover 20 is also provided with threaded spigots 23 and 24 on the upper side of the cover and continuations thereof, designated 23A and 24A, project from the opposite side of the cover downwardly into the container.
  • Conduits 30 and 40 project into respective ones of the spigots 24 and 23 and sealing is provided in a conventional manner by respective ring or gland nuts 25 and 26 having flanges cooperating with packing material 27.
  • the projecting portions 23A and 24A shown in Figure-1 are dispensed with and in place thereof inlet and outlet conduits 30 and 40 may, if desired pass through the respective spigots 24 and 23 and project downwardly a selected amount into the container to provide the necessary liquid free space in the upper portion of the container,
  • Figure 2 also illustrates another important variant in that the liquid free volume is located exteriorly of the trap.
  • the container 10 is provided with internal threads 11 at a position spaced downwardly from the upper edge 12 of the container so that the volume 50, provided for collecting the excess liquid, i.e. the liquid in the conduits, is located entirely exteriorly of the trap.
  • the cover 20 is provided with external threads 21 that mate with the threads 11 on the container.
  • a gasket 22 is interposed between the lower edge of a peripheral rim on the cover and a ledge on the container.
  • seal 22 need only prevent the egress of liquid from the container as opposed to air.
  • inlet and outlet conduits 30 and 40 could project a selected amount into the container such that the liquid free volume is partially interiorly and partially exteriorly of the trap.
  • the embodiment illustrated in Figure 3 is similar to the embodiment illustrated in Figure 1 and differs therefrom by having conduits 30 and 40 communicating with the interior of the container by way of a common opening 70.
  • the common opening 70 is provided by a funnel-like element 71 located in the container and having an upper outwardly directed flange 72 clampingly engaged between the upper peripheral edge of the container and the cover 20.
  • inlet conduit 30 projects into a further conduit 30A (larger in diameter than conduit 30) to an extent such that the lower open end thereof is below the normal liquid level 80.
  • Conduit 30A projects sufficiently downwardly into the container such that the liquid free volume 50 is greater than the volume of liquid contained in the lower end of inlet conduit 30 and the further conduit 30A.
  • the conduits 30 and 40 project preferably an equal amount into the container.
  • a screen or strainer 100 may be placed in the container to prevent the through flow of accidently dropped possessions.
  • the height of the screen need be no more than the normal water level 62 in the container.
  • the container 10 is circular and in some instances may take up more space than available wherein it is to be installed.
  • Figures 5, 6, and 8 to 10 there is illustrated an embodiment, with various modifications thereto, wherein the container is generally rectangular in cross-section, minimizing the space required for the trap.
  • the sink trap as shown therein comprises a molded plastics container 10B having a cover 20B detachably held thereon by one or more (preferably 2 or 4) over-center draw down clamps 200, (See Figures 7 and 10).
  • the container 10B has a lug 91 secured to the wall thereof (or molded integrally therewith) for each clamp.
  • lug 91 On the lower edge of lug 91 there is a groove 92 for receiving the free end of the latch portion of the draw down clamp (or a shaft on the free end thereof).
  • lip 95 of the groove 92 may be partially flexible so that the shaft can be pressed into the groove and held therein by the lip 95.
  • the cover 20B has passages therethrough for inflow of liquid into the container and outflow of liquid therefrom through respective conduits 30 and 40 connected to such passages.
  • spigots 23A and 24A are formed integrally with the cover as in the embodiment illustrated in Figure 1.
  • the inflow and outflow conduits may project downwardly into the container as per the embodiment illustrated in Figure 2.
  • the container 10B is provided with a ledge 10C, on the internal surface, spaced downwardly from the upper edge 10D of the container so that when the cover is mounted on the container it is spaced downwardly from the upper edge of the container.
  • the additional volume 50 for the container i.e. liquid free volume
  • the liquid free volume 50 would be entirely exteriorly of the trap or if short spigots were used then a portion of the liquid free volume would be interiorly of the trap and the remaining portion exteriorly of the trap.
  • FIG. 7 Various constructional details are illustrated in Figure 7 to 10 which are believed self-evident therefrom and thus will only be described briefly.
  • the ledge 10C is flat, while the corresponding ledge 10E in the embodiment illustrated in Figure 9 slopes inwardly, downwardly into the container.
  • the cover 20C illustrated in Figures 6 and 7 has a flange 20D projecting downwardly therefrom into the container reinforcing the cover to evenly distribute the force from the tie-down clamp 200 in compressing the gasket 203 disposed between the cover and the ledge 10C.
  • an o-ring seal 204 is interposed between the sloping shoulder 10E and a groove around the periphery of the cover.
  • the cover designated 20D has upstanding flanges 20F serving as an abutment for the bent-over loop of the tie-down clamp 200 and reinforcement of the cover.
  • the over centre tie down clamp 200 shown in Figures 7 and 10 consists of a bent-over loop 201 which pivotally attaches to a latch 202 by way of lugs projecting into respective ones of a pair of apertures in the latch.
  • the latch member 202 is a short length of an extrusion of plastics material having a cross-sectional shape clearly illustrated in Figures 7 and 10.
