Definitions

  • the present invention concerns a closed floor outlet or floor drain and a water seal or trap for floor outlets or floor drains of the kind that is used in bathrooms, toilets, kitchens etc.
  • Water traps are used in floor drains to prevent air and smell from the sewage system from finding their way up into inhabited spaces.
  • water traps odor seals
  • the outflowing water is forced to flow first below a first screen and thereafter over a second screen, the upper edge of which being located higher than the lower edge of the first screen so that remaining water prevents the passage of air.
  • the two screens or shutters of the water trap also act together to make the clearing of sewage tubes, starting from for instance floor drains, more difficult.
  • seals provided openings through which a cleaning helix can be pushed in after removal of the seal. These openings are however small and the clearing can be difficult and it may often be very difficult to remove the seals.
  • One object of the invention is to provide an improved floor drain, that reduce sedimentation and retention of floating matter in the floor drain and that thereby remain more clean and hygienic.
  • the inlet flow cross section is small the water will have a fair speed when flowing in, which cause light organic pollutions, that are the problem, to be flushed on below the screen or lip projecting downwards from above, then to rise to the surface in the following dammed up part of the water trap.
  • said dammed up part that preferably has a larger volume the pace will be lower than in the inlet and the organic lighter material can rise to the surface, then to accompany the water that flow over the second, from below protruding, barrier or threshold and over into the outlet.
  • the entire inside of the floor drain or scupper, but for inlet and outlet is used as a dammed up water reservoir between inlet and outlet.
  • Preferred embodiments of the invention thus result in a floor drain that is hygienic and that has less tendency to become clogged than known floor drains and that make full use of the available space for the water trap.
  • water is supplied from for instance a bathtub or washstand via a separate tube, the lower end of which extends down into the water.
  • the large flow quantities and speeds of water from the tub efficiently flush the water trap clean.
  • a further object of the invention is to considerably facilitate outlet tube clearing at floor drains.
  • the new floor drain embodiment can be used in thinner roofs (floors).
  • floors floors
  • the outlet funnel part it may serve as an efficient stop, preventing the insert from being pushed into the outlet and also providing a good grip when the insert is to be removed for cleaning purposes.

  • fig 2 a floor drain according to a preferred embodiment of the invention
  • fig 3 the stationary or main part of a floor drain, that is mounted or cast integral in the floor
  • fig 4 and 5 respectively details thereof
  • fig 6 an insert for the establishing of an outlet barrier in a water trap
  • fig 7 the insert in fig 6 on its place in a floor drain

  • the fixed main part 1 of the floor drain comprise an upper opening 2 and a circular flange 3 extending radially out from this.
  • an inward extending step or shoulder 4 is arranged with a short cylindric wall 5 between the shoulder and the opening.
  • the fixed part 1 of the floor drain tapers with a lower part 6 somewhat down towards a flat bottom 7.
  • a horizontal tube 8 extends for connection to the sewer system.
  • alternating groves 9 and ridges 10 are arranged above the shoulder.
  • a flooring material 11 for instance in the shape of a plastic flooring or some other sealing layer is arranged on the floor drain and the sealing layer has been folded or formed down into the floor drain so that the bottom side will be in contact with said ridges 9.
  • the plastic flooring material is pressed against the ridges 9 by a clamping ring 12 of rubber, that has been pushed down into the floor drain and that on the inside is supported by a ring 13 of metal or plastic, and that has an L-shaped cross section.
  • the clamping ring 12 is provided with a downwards extending, all around going bead 14, that press downward against a floor drain insert 15 that in turn is pressed against an O-ring arranged in the shoulder.
  • the grid of the floor drain rests on the clamping ring or the support ring of this.
  • the above described connection to the flooring material 11 guarantees a very good seal.
  • the outer rubber ring of the clamping ring is sealed against the surface of the flooring material and against the floor drain insert 15 lying on the shoulder 4 and thereby preventing water from entering between flooring material and the inside of the floor drain.
  • the bead 14 and the pressing of the flooring material against the surrounding ridges 9 secure a sealing that prevents water from entering between floor and flooring material and the floor drain.
  • a two step sealing is achieved.
  • the cylindrical part 5 may be made so that it is inclined slightly inward and upward securing that the clamping ring when mounted is guaranteed to press downward all the time.
  • the rubber ring 12 may be shaped with an upper edge that is higher at the outside so that it at movement upward tries to become wider, securing a stable seating and pretension outward and downward.
  • the support ring comprise on its upper side an horizontal outward directed flange, which serve as a contact part when the clamping ring 12 is pressed down.
  • the clamping ring is after being mounted seated so good that you for its removal at first have to pull up the support ring 13. If the support ring and clamping ring are vulcanized together you may have to destroy the clamping ring to get it loose.
  • the rubber clamping ring and the support ring may be glued or vulcanized together, but preferably they are separate. When the clamping and sealing rubber ring is mounted this is preferably done with the support ring on its inside. In this way the clamping ring will during the movement downwards be pressed firmly against the floor covering pulling this down firmly against the floor drain housing.
  • the support ring When on the other hand the clamping ring is to be removed the support ring is removed first, it is easier to get a grip on, and can take greater pulling forces than the clamping ring. As soon as the support ring is removed the radial pressure on the clamping ring is reduced and the flexible clamping ring can be removed allowing the removal of the floor drain insert. The removal of the clamping ring does thus not have to result in an undesired pulling upwards of the flooring in the floor drain inlet. If friction alone do not give a sufficient retention between support ring and clamping ring these may be provided with cooperating groves and ridges.
  • an inlet insert 15 for the floor drain is shown that comprise an upper funnel like part 16 that in its upper end transcends into flat circular flange 17, intended for instance to be placed below the above mentioned clamping ring 12 with a sealing ring 18 between the flange 17 of the insert 15 and the shoulder 4 (fig 5).
  • the funnel like part 16 of the insert transcends in the lower end into a vertical tube
  • an inner tube 20 is displacably arranged and provided with a seat 21 in the upper end and with a ball 22 placed below said seat.
  • the ball and the seat together constitute a non return valve by the ball being filled with air and by the water in the water trap pressing it up against the seat.
  • the ball seat provided tube is displacable height- wise for adjustment so that the ball can be pressed down into the floor drain by the weight of water in the funnel like part without the water having to stand over the edge of the floor drain but is otherwise kept lifted by the water in the floor drain.
  • the inner tube 20 is in its lower end provided with a flange 23 facing outward and preventing the inner tube from being pushed upward out of the outer tube 19 at excess pressures in the sewer system or in the water trap.
  • the inner tube can however be pulled down, to secure the floating of the ball on the water if for instance supplementary rings have been used to raise the top of the floor drain.
  • distance elements in the shape of short tube pieces 24, are placed between the outward flange 23 of the inner tube 20 and the lower end of the outer tube 19 to prevent a lifting up of the inner tube.
  • the tube pieces advantageously have the same height as the supplementary rings for the floor drain.
  • a sealing ring is arranged between the vertical tube 19 and the seat provided inner tube 20.
  • the seat may be of elastic material, for instance rubber, and may actually also take care of the sealing between seat and the vertical tube 19.
  • a circular grove 26 is arranged and outside of this a downward facing pipe socket 27 is arranged.
  • the material on the inside of the groove can be broken away providing an opening through which, with an intermediate seal, a tube 28 from a washstand, shower, sink or bathtub can be pushed down.
  • This tube is pushed down so that its lower end ends below the water level 29 so that also this connection (tube 28) constitute an upper water trap screen or lip.
  • the water flows directly down into the floor drain on the outlet side of the non return valve constituted by ball and seat. In this way one does not risk flooding of the floor, when for instance water from a bathtub is released. Furthermore this supply of fast flowing water clean the floor drain efficiently. It is of course also possible to integrate a non return valve in the extra inlet from bath tub or wash basin.
  • a part 30 is shown that constitute outlet threshold in the water trap.
  • This threshold part 30 is intended to be pushed into the outlet tube 8 of the floor drain.
  • the threshold part 30 is essentially tube-shaped with a pair of outer sealing rings 31 or beads if the part is made of rubber or other elastic material. In its towards the inner of the floor drain facing end the tube shape transcends into an ending rounded wall 32 that extends up to an opening 33. Water may thus flow over the edge of the opening 33 and out into the outlet and this part constitute together with the downward extending tube part of the funnel-like part a water trap that retain water in the floor drain.
  • FIG. 12 alternative shapes are shown for the threshold part.
  • the version in figure 13 includes a rubber tube 35 provided with sealing flanges and that in its towards the floor drain facing end is semi closed by an end 36 forming the outlet threshold for the water.
  • the threshold part 30 or 35 of rubber or with seals and with appropriate dimensions it may easily be removed when the outlet from the floor drain has to be cleaned up and the cleaning up is in particular facilitated by the entire cross section of the outlet tube becoming accessible.
  • FIG. 14 a - g another outlet insert version is shown with a broad slightly flattened funnel part situated inside the floor drain and a tube part provided with a seal.
  • the funnel like part is broader than the cross section of the outlet tube preventing the insert from being pushed out through the outlet and also provide a good grip for removal of the insert for cleaning
  • the water level in the floor drain may be adjusted if so is required in order to achieve the proper function of the non return valve.
  • the versions shown in figures 12 and 13 provide a large degree of height adjustment.
  • a fair volume of water in the floor drain is desired in order to secure that the water trap does not dry out, to which also the non return valve in the shape of ball and seat contribute since there is no open water surface for the water to evaporate from to the surrounding above the floor drain.
  • An essential advantage with the above described water trap part is that it can be mounted in many today existing floor drains and scuppers respectively thereby improving the function of these and not least drastically reduce the risk of water damages.
  • a conventional floor drain with an upper lip 50, a lower threshold 51, a dammed up volume 52 in a main floor drain part 53 is shown.
  • Water can flow down into the floor drain from the floor via a grid 54 or from a bathtub via a tube 55.
  • Light pollutions as skin deposits and fat rise to the surface in the dammed up volume 52 and remain as a top layer, while the water without disturbing this layer can flow out below the upper lip 50 and thereafter over the threshold 51.
  • the fit of the tubes is such that the height and angle of the floor drain can be adjusted not only by cutting but also by an adjustment of the insertion depth of tubes or pins.
  • the short tubes integral with the bottom may be provided with a few inner longitudinal ribs.
  • tubes may be arranged on the sides of the floor drain for the insertion of support legs. In this way the adjustment span can be increased and it will not be necessary to cut away short tubes integrated with the bottom of the floor drain if there is no, or very little space available below.
  • the primary objects of a floor drains is of course to drain away water without allowing bad smell or bacteria in return, preferably even if the drain is not used for a long time.
  • the floor drain is as service free as possible, but if needed can be cleaned with as little trouble and destruction as possible.
  • a further wish is of course that no water should leak into the building.
  • the floor drain can resist high back pressures in case of gas sabotage against the sewer systems.
  • An efficient rat stop is also a good thing.
  • the non return valve togheter with the very efficent clamping ring will efficiently prevent sewage water from flowing back into the floor drain contaminating this as well as the the floor above the floor drain.
  • Embodiments of the invented floor drain can fulfill all these requirements.
