Definitions

• the present invention relates to an arrangement in a drain trap in accordance with the preamble of claim 1. This type of arrangement aids the assembly of a floor drain.
• Said floor drain is used especially to conveying waste water from the surfaces of the floor and the drain fixtures connected to the floor drain into the sewage system of the property.
• the floor drain comprises a bowl-like vessel with a drain trap and side inlets for receiving water or other liquid conveyed to the drain.
• the top surface of the floor drain conventionally has a screen arranged at floor level.
• the object of the present invention is, thus,. to develop an arrangement that provides a simple solution to the above-mentioned problems caused by prior-art drawbacks. This object is achieved in such a manner that the arrangement in a drain trap is, in accordance with the present invention, provided with the characteristic features defined in the claims. More specifically, the arrangement according to the invention is mainly characterised by what is disclosed in the characterising part of claim 1.
• top edge As it is presented in the attached figures- r
• Figure 1 shows the entire floor drain fully assembled
• Figure 2 shows the frame of the floor drain
• Figure 3 shows the frame of the floor drain cut at point A-A of Figure 1 ,
• Figure 4 shows a no-return pipe installable in the frame as seen obliquely from the top
• Figure 5 shows the no-return pipe of Figure 4 as seen obliquely from the bottom
• Figure 6 shows the floor drain cut at point B-B of Figure 1
• Figure 7 shows the floor drain cut at point C-C of Figure 6
• Figure 8 shows the floor drain partially cut at the location of the support collar and support edge.
• the present arrangement in a drain trap relates, in particular, to floor drains 1 , the assembly of which can be substantially facilitated by this solution.
• the floor drain comprises a frame 2 that surrounds the water conveyed through a drainage aperture 3 into its interior 4.
• the frame is " made up of a shell 5 and a bottom 6 attached thereto that is opposite the drainage aperture.
• One or more side inlets 7 are connected to the shell of the frame to convey water to the floor drain from various water fixtures and machines.
• the water that accumulates into the floor drain is led on to the sewer through an outlet 8 connected to the shell.
• a drain trap 9 is formed in the interior 4 of the floor drain 1 to stop the gases emitted from the sewer from entering the room space through the outlet 8.
• This drain trap is achieved by leading from the direction of the drainage aperture 3 to the interior a no-return pipe 11 that extends to the bottom cup 10 formed below the bottom edges in the ' side and outlets.
• This type of bottom cup can also be achieved by damming it up at the side inlets and outlet.
• the bottom cup is dammed up at the outlet.
• the no-return pipe is arranged to close the interior 4 of the floor drain 1 in an air-tight manner by extending a drainage flange 12 from its drainage aperture-side end to the inner surface 13 in the interior of the shell.
• the drainage flange settles substantially tightly against the inner surface, and the tightness is preferably ensured by a seal 15 arranged on the outer edge of the drainage flange.
• the structure is shown in Figure 6, for instance.
• Said drainage flange 12 further comprises, in the manner shown in Figures 4 and 5, for example, a special collar 16 that extends from the outer edge 14 of the drainage flange toward the drainage aperture 3.
• the collar is arranged to settle against the inner surface 13 of the shell 5 when the drain trap 9 is formed.
• they comprise in an embodiment of the floor drain at least one groove 17 and a guide 18 to be led to the groove to position these parts of the floor drain simply together.
• the groove 17 forming the first connecting means is arranged on the collar 16 of the drainage flange 12, whereas the guide 18 forming the second connecting means is arranged on the shell 5 of the collar 16.
• the connecting means form a flow opening 19 at the side inlet as a tongue and groove-type structure comprising a protrusion and slide.
• These opposite connecting means may also be located at several locations along the circumference of the collar.
• the connecting means can also be implemented broader than in the solution of the figures.
• the alignment of the no-return pipe and floor drain can also be aided by arranging in the no-retum pipe a plane surface 20 in the direction oriented toward the inner surface 13 of the shell 5.
• This plane surface is arranged to interact with a frontal surface 21 , which is in the shell and extends into the interior, to guide the no-return pipe in place in the direction of the bottom.
• the opposite plane surface and frontal surface are shown in Figure 6.
• the no-retum pipe 10 can be equipped with a special support collar 22 that extends toward the bottom 6, as shown in Figures 4 and 5, for instance.
• This type of support collar is, in turn, arranged to interact with support edges 23 extending from the shell 5 toward the interior 4 on opposite sides of the interior, as shown in Figure 2.
• This interaction is shown schematically in Figure 8.
• the support collar 22 is dimensioned in length to fit exactly between the opposite support edges 23.
• the support collar 22 is dimensioned in length to fit exactly between the opposite support edges 23.
• the support collar 22 is formed on the outer edge of the drainage flange 12 Over a distance of 90 to 180 degrees.
• the end edge of the support collar can further be arranged to form an approximately 90 to 120 degree angle with the bottom edge 25 of the support collar.
• the physical message provided by the support collar 22 during installation concerning the incorrect location of the no-return pipe 11 is especially significant to the resident of the apartment cleaning the floor drain. Because the desired drain trap cannot be achieved by the no-return pipe which in the incorrect position stays clearly too high, the person cleaning the floor drain receives a clear message of the need to fix the position of the no-return pipe so that it would settle functionally in the correct location in the bottom cup 10.
• the floor drain can also be equipped with the above-mentioned connecting means.
