Abstract

A discharge chute (1) is at the top provided with an outwardly directed flange (7) which is engaged by a floor mat (3), preferably of a plastic material, and includes a carrier member (8) for grating means (9) which carrier member engages the floor mat and cooperates through mounting means (16) with a mounting flange (14) provided in the discharge chute in such a way that the carrier member press the floor mat against the outwardly directed flange of the discharge chute. In order to construct a device at said discharge chute such that an optimum clamping effect on the floor mat is always present without repeated subsequent tightening of the mounting means, the carrier member (8) includes a central portion (11) which at the top transfers into an outwardly directed clamping flange (12) for clamping the floor mat (3) against the outwardly directed flange (7) of the discharge chute (1) and which down below transfers into an inwardly directed support flange (13) which is engaged by the grating means (9) and which through the mounting means (16) cooperates with the mounting flange (14) of the discharge chute, the carrier member (8) further consists of or includes resilient material so that the clamping flange (12) thereof can adapt to the floor mat (3) even if said floor mat is compressed, and the length of the carrier member (8) is less than the distance between the outwardly directed flange (7) of the discharge chute (1) and the mounting flange (14) provided in the discharge chute so that the support flange (13) is not brought in contact with the mounting flange when said support flange is in its lowermost position. <IMAGE>

Description

KLEMANORDNING VED AVLØPSRENNE ELLER LIGNENDE. CLAMPING DEVICE AT DRAIN GUTTER OR SIMILAR.

Den foreliggende oppfinnelse vedrører en klemanordning ved avløpsrenne eller lignende, hvorved avløpsrennen oventil har en utoverrettet flens mot hvilken et gulvbelegg, fortrinnsvis av plastmaterial, ligger an, og hvorved avløpsrennen oppviser en bæredel for et silorgan, hvilken bæredel ligger an mot gulvbelegget og via festeorgan samvirker med en i avløpsren-nen anordnet montasjeflens på en slik måte at bæredelen presser gulvbelegget mot avløpsrennens utoverrettede flens og hvilken bæredel oppviser en sentral del som oventil går over i en utoverrettet klemflens for å klemme gulvbelegget mot av-løpsrennens utoverrettede flens, og som nedentil går over i en innoverrettet støtteflens, som silorganet ligger an mot, og via hvilken festeorganene samvirker med avløpsrennens montasjeflens The present invention relates to a clamping device for a drainage channel or the like, whereby the drainage channel at the top has an outwardly directed flange against which a floor covering, preferably made of plastic material, rests, and whereby the drainage channel has a support part for a strainer, which support part rests against the floor covering and cooperates via fastening means with a mounting flange arranged in the drain in such a way that the carrier part presses the floor covering against the outward-directed flange of the drain and which carrier part has a central part which at the top passes into an outward-directed clamping flange to clamp the floor covering against the outward-directed flange of the drain, and which goes below over into an inwardly directed support flange, against which the strainer member rests, and via which the fastening members cooperate with the drain chute's assembly flange

Liknende klemanordninger (klemringer) ved en gulvsluk er tid-ligere kjent fra eksempelvis SE-A-9003167-5 og DE-Ul-8913129.0. Klemanordningen kjent fra SE-A-9003167-5 er utformet med bl.a. relativt stor godstykkelse og den fremfor alt derav, men også avhengig av materialvalget, manglende elasti-sitet i anordningen, medfører at klemvirkningen mot gulvbelegget svekkes etter hvert, for eksempel på grunn av at gulvbelegget blir presset sammen. Festeorganet må hele tiden strammes, og det er fare for at bæredelen til slutt bringes til anlegg mot montasjeflensen, slik at ytterligere tiltrekking av festeorganet blir umulig, eller ikke gir noen bedret klemvirkning om gulvbelegget. I klemanordningen kjent fra DE-Ul-8913129.0 er bæredelens nedentil beliggende støtteflens i direkte forbindelse med eller anliggende mot monteringsflen-sen. Dette medfører at ettertrekking av festeorganet for å motvirke svekket klemvirkning mot belegget ikke kan foretas. Klemanordningens klemvirkning går derfor raskt tapt. Similar clamping devices (clamping rings) for a floor drain are previously known from, for example, SE-A-9003167-5 and DE-Ul-8913129.0. The clamping device known from SE-A-9003167-5 is designed with, among other things, relatively large material thickness and the, above all, but also depending on the choice of material, lack of elasticity in the device, means that the clamping effect against the floor covering gradually weakens, for example because the floor covering is pressed together. The fastening element must be constantly tightened, and there is a risk that the carrier part will eventually come into contact with the mounting flange, so that further tightening of the fastening element becomes impossible, or does not provide any improved clamping effect on the floor covering. In the clamping device known from DE-Ul-8913129.0, the supporting flange of the carrier part located below is in direct connection with or abutting against the mounting flange. This means that retraction of the fastening element to counteract the weakened clamping effect against the coating cannot be carried out. The clamping effect of the clamping device is therefore quickly lost.

Formålet med den herværende oppfinnelse er å eliminere ovennevnte problem og å utforme den innledningsvis definerte klemanordning slik at den optimale klemeffekt om gulvbelegget til enhver tid foreligger uten at tiltrekking av festeorganet må gjentas senere. The purpose of the present invention is to eliminate the above-mentioned problem and to design the initially defined clamping device so that the optimal clamping effect on the floor covering is present at all times without the tightening of the fastening means having to be repeated later.

Formålet oppnås ifølge oppfinnelsen ved at bæredelen består av eller oppviser fjærende material, slik at dens klemflens kan føye seg etter gulvbelegget selv om dette blir presset sammen, og at lengden på den sentrale del er mindre enn avstanden mellom avløpsrennens utoverrettede flens og montasjeflensen anordnet i avløpsrennen, slik at støtteflensen ikke kommer i kontakt med montasjeflensen når støtteflensen befinner seg i en nedre stilling. The purpose is achieved according to the invention in that the support part consists of or exhibits springy material, so that its clamp flange can follow the floor covering even if it is pressed together, and that the length of the central part is less than the distance between the outward facing flange of the drain and the assembly flange arranged in the drain , so that the support flange does not come into contact with the mounting flange when the support flange is in a lower position.

Ved at bæredelen består av eller oppviser fjærende materiale, oppnås optimal klemming av gulvbelegget mellom bæredelens klemflens og avløpsrennens utoverrettede flens. Gjennom den angitte lengde på den sentrale del kan elastisiteten oppnådd for bæredelen utnyttes maksimalt uten at bæredelens støtte-flens noen gang kommer i kontakt med montasjeflensen. Det oppnås en vesentlig bedre og mer konstant tetning mellom gulvbelegget og avløpsrennen sammenlignet med kjente klemanordninger. As the support part consists of or exhibits springy material, optimal clamping of the floor covering is achieved between the support part's clamping flange and the drainage channel's outwardly directed flange. Through the specified length of the central part, the elasticity achieved for the support part can be utilized to the maximum without the support flange of the support part ever coming into contact with the mounting flange. A significantly better and more constant seal is achieved between the floor covering and the drainage channel compared to known clamping devices.

Oppfinnelsen vil nedenfor bli beskrevet nærmere under henvis-ning til vedlagte tegninger, hvor: The invention will be described in more detail below with reference to the attached drawings, where:

Fig. 1 viser en plantegning av en avløpsrenne med en klemanordning ifølge oppfinnelsen; Fig. 2 viser et snitt av avløpsrennen etter snittlinjen II-II på fig. 1; og Fig. 3 viser et snitt av avløpsrennen etter snittlinjen II—II på fig. 1, hvorved avløpsrennen oppviser en klemanordning ifølge oppfinnelsen med et festeorgan i en alternativ utfø-relsesform. Fig. 1 shows a floor plan of a drainage channel with a clamping device according to the invention; Fig. 2 shows a section of the drainage channel along the section line II-II in fig. 1; and Fig. 3 shows a section of the drainage channel along the section line II—II in fig. 1, whereby the drainage channel has a clamping device according to the invention with a fastening device in an alternative embodiment.

Den på tegningene viste avløpsrenne 1 er beregnet på å bli anordnet slik i et gulv 2 at et gulvbelegg 3, fortrinnsvis av plastmaterial, anbrakt på gulvet 2 kan tilsluttes den. Hen-sikten med dette er at vann på gulvbelegget 3 skal kunne renne ned i avløpsrennen 1 og via denne videre ut i et avløps-system (ikke vist). The drainage channel 1 shown in the drawings is intended to be arranged in a floor 2 in such a way that a floor covering 3, preferably made of plastic material, placed on the floor 2 can be connected to it. The purpose of this is that water on the floor covering 3 should be able to flow down into the drainage channel 1 and via this further into a drainage system (not shown).

Avløpsrennen 1 er firkantet og har fortrinnsvis en rektangulær form. Dens bunn 4 har en åpning 5, og den heller slik mot åpningen 5 at oppsamlet vann renner ned i åpningen 5 og via denne ned i avløpssystemet. Avløpsrennen 1 har videre fire sidevegger 6 som er innrettet vertikalt, eller i hovedsak vertikalt, når avløpsrennen 1 er anbrakt i funksjonsstilling i gulvet 2. Oventil oppviser sideveggene 6 en utoverrettet flens 7 som kan danne en rett, eller i hovedsak rett, vinkel med den respektive sidevegg 6, og som kan oppvise en noe skrått oppoverrettet del. The drainage channel 1 is square and preferably has a rectangular shape. Its bottom 4 has an opening 5, and it slopes towards the opening 5 in such a way that collected water flows down into the opening 5 and via this into the drainage system. The drainage channel 1 further has four side walls 6 which are aligned vertically, or essentially vertically, when the drainage channel 1 is placed in a functional position in the floor 2. Above, the side walls 6 have an outwardly directed flange 7 which can form a right, or essentially right, angle with the respective side wall 6, and which may have a somewhat obliquely upwards part.

Den utoverrettede flens 7 forløper rundt langs hele avløps-rennen 1 og er fortrinnsvis noe forsenket i forhold til gulv-planet, slik at gulvbelegget 3 kan ligge an mot dens overside uten at det dannes en terskel som hindrer vann fra å renne ned i avløpsrennen 1. The outwardly directed flange 7 extends around the entire length of the drainage channel 1 and is preferably somewhat recessed in relation to the floor plane, so that the floor covering 3 can rest against its upper side without forming a threshold that prevents water from flowing down into the drainage channel 1 .

En bæredel 8 kan plasseres i avløpsrennen 1, og i denne bæredel 8 kan et silorgan 9 bli plassert. Silorganet 9 er utformet som en firkantet ramme 10 med et gitter som gjør det mu-lig for vann å renne ned i avløpsrennen 1, men hindrer en fra å trø eller kjøre ned i denne. Silorganets 9 høyde er avpas-set slik at dets overside ligger i høyde med bæredelens 8 overside, eller noe nedenfor bæredelens 8 overside. A support part 8 can be placed in the drainage channel 1, and in this support part 8 a strainer 9 can be placed. The strainer 9 is designed as a square frame 10 with a grid which makes it possible for water to flow down the drainage channel 1, but prevents one from wading or driving down it. The height of the strainer 9 is adjusted so that its upper side is at the same height as the upper side of the carrier part 8, or slightly below the upper side of the carrier part 8.

Bæredelen 8 oppviser en sentral del 11 som oventil går over i en utoverrettet klemflens 12, og som nedentil går over i en innoverrettet støtteflens 13. Lengden på den sentrale del 11 er vesentlig mindre enn avstanden mellom den utoverrettede flens 7 og en montasjeflens 14 anordnet i avløpsrennen 1, slik at støtteflensen 13 ikke kan komme i kontakt med montasjeflensen 14. Klemflensen 12 er innrettet til å ligge an ovenfra mot gulvbelegget 3 og presse dette nedover mot den utoverrettede flens 7, slik at det oppnås god tetning mellom gulvbelegget 3 og den utoverrettede flens 7, hvorigjennom vann hindres fra å trenge ned i gulvet 2 langs avløpsrennen 1. Denne tetning blir spesielt fordelaktig ettersom verken gulvbelegget 3, den utoverrettede flens 7 eller klemflensen The support part 8 has a central part 11 which at the top passes into an outwardly directed clamping flange 12, and which at the bottom passes into an inwardly directed support flange 13. The length of the central part 11 is substantially smaller than the distance between the outwardly directed flange 7 and a mounting flange 14 arranged in drainage channel 1, so that the support flange 13 cannot come into contact with the assembly flange 14. The clamping flange 12 is arranged to rest against the floor covering 3 from above and press this downwards against the outward facing flange 7, so that a good seal is achieved between the floor covering 3 and the outward facing flange 7, through which water is prevented from penetrating into the floor 2 along the drainage channel 1. This sealing is particularly advantageous as neither the floor covering 3, the outward facing flange 7 nor the clamp flange

12 har hull for festeorgan eller lignende. 12 has a hole for a fastening device or the like.

Bæredelens 8 grunnform er fortrinnsvis slik at vinkelen a mellom den sentrale del 11 og klemflensen 12 er mindre enn 90°, for eksempel ca. 85°, hvorigjennom klemflensens 12 ytre deler 15 kan bli brakt til anlegg mot gulvbelegget 3 med større trykk enn dens indre deler. Klemflensens 12 utgangs-stilling er vist med heltrukne linjer i fig. 2. Bæredelen 8 består fortrinnsvis av, eller oppviser, et slikt fjærende materiale at klemflensen 12 kan bli brakt til å endre stilling i forhold til den sentrale del 11, slik at nevnte vinkel a øker til en større vinkel ot, fortrinnsvis på maksimalt 90°, når klemflensen 12 ved montering av bæredelen 8 ligger an mot gulvbelegget 3, og bæredelen 8 blir utsatt for krefter i retning nedover i forhold til avløpsrennen 1, hvorved større deler av klemflensens 12 bredde blir brakt til anlegg mot gulvbelegget 3. Dog vil klemflensens 12 ytre deler 15 fremdeles ligge an mot gulvbelegget 3 med større trykk enn dens indre deler. Sistnevnte stilling for klemflensen 12 er vist med punktstreklinjer i fig. 2 og med heltrukne linjer i fig. 3. The basic shape of the carrier part 8 is preferably such that the angle a between the central part 11 and the clamping flange 12 is less than 90°, for example approx. 85°, through which the outer parts 15 of the clamping flange 12 can be brought into contact with the floor covering 3 with greater pressure than its inner parts. The initial position of the clamping flange 12 is shown with solid lines in fig. 2. The support part 8 preferably consists of, or exhibits, such a springy material that the clamping flange 12 can be brought to change its position in relation to the central part 11, so that said angle a increases to a larger angle ot, preferably of a maximum of 90° , when the clamping flange 12 when mounting the support part 8 rests against the floor covering 3, and the support part 8 is exposed to forces in a downward direction in relation to the drainage channel 1, whereby larger parts of the width of the clamping flange 12 are brought into contact with the floor covering 3. However, the clamping flange 12 outer parts 15 still lie against the floor covering 3 with greater pressure than its inner parts. The latter position for the clamping flange 12 is shown with dotted lines in fig. 2 and with solid lines in fig. 3.

Bæredelen 8 kan trekkes ned i avløpsrennen 1 ved hjelp av festeorgan 16 av egnet type. Disse er trædd gjennom hull 17 i støtteflensen 13, og de er skrudd ned i, eller samvirker på annen måte med montasjeflensen 14, slik at bæredelen 8 kan trekkes nedover i forhold til montasjeflensen 14 ved å skru ned festeorganene 16 i forhold til denne. På denne måte kan bæredelen 8 skrus så langt nedover at klemflensen 12 presser gulbelegget 3 nedover mot den utoverrettede flens 7 med kraf-tig trykk, hvilket kan opprettholdes over lang tid, selv om gulvbelegget 3 blir trykket sammen. Denne funksjon forbedres ved at bæredelen 8 har fjærende egenskaper og/eller gjennom bæredelens 8 form og fremfor alt klemflensens 12 grunnform. Også de nedenfor beskrevne fjærorgan medvirker i en viss grad til denne forbedrede funksjon. The support part 8 can be pulled down into the drainage channel 1 by means of a fastening device 16 of a suitable type. These are threaded through holes 17 in the support flange 13, and they are screwed down into, or cooperate in some other way with, the mounting flange 14, so that the carrier part 8 can be pulled down in relation to the mounting flange 14 by screwing down the fastening means 16 in relation to this. In this way, the support part 8 can be screwed down so far that the clamping flange 12 presses the yellow covering 3 downwards against the outward facing flange 7 with strong pressure, which can be maintained over a long time, even if the floor covering 3 is pressed together. This function is improved by the support part 8 having resilient properties and/or through the shape of the support part 8 and above all the basic shape of the clamping flange 12. The spring means described below also contribute to a certain extent to this improved function.

Ved utførelsen vist på fig. 2 består hvert festeorgan 16 av en skrue 18 med et gjenget parti 19 ved hjelp av hvilket den er fastskrudd i et gjenget hull 20 i montasjeflensen 14. Skruen 18 kan skrus ned i hullet 20 til klemflensen 12 oppnår den ovennevnte klemeffekt mot gulvbelegget 3. In the embodiment shown in fig. 2, each fastening device 16 consists of a screw 18 with a threaded part 19 by means of which it is screwed into a threaded hole 20 in the mounting flange 14. The screw 18 can be screwed down into the hole 20 until the clamping flange 12 achieves the above-mentioned clamping effect against the floor covering 3.

Ved utførelsen vist på fig. 3 består hvert festeorgan 16 av en annen type skrue 21, nemlig en skrue med en del 22 som med frigang rager ned gjennom et hull 23 i montasjeflensen 14. Delen 22 oppviser et gjenget parti 24 på hvilket er påskrudd en mutter 25, og mellom montasjeflensen 14 og mutteren 25 er det plassert minst ett fjærorgan 26, slik at dette via skruen 21 utøver en nedoverrettet kraft på bæredelen 8 og dennes klemflens 12. In the embodiment shown in fig. 3, each fastening member 16 consists of a different type of screw 21, namely a screw with a part 22 which with clearance projects down through a hole 23 in the mounting flange 14. The part 22 has a threaded part 24 on which a nut 25 is screwed, and between the mounting flange 14 and the nut 25, at least one spring member 26 is placed, so that via the screw 21, this exerts a downward force on the carrier part 8 and its clamping flange 12.

Fjaerorganet 2 6 kan være en på skruen 21 trædd spiralf jær, en eller flere tallerkenfjærer, eller annen egnet type av konstant virkende fjærer med den nødvendige styrke. The spring element 2 6 can be a spiral spring threaded onto the screw 21, one or more disc springs, or another suitable type of constantly acting spring with the required strength.

Støtteflensen 13 oppviser fortrinnsvis forsenkede partier 27 rundt hvert hull 17 for festeorganene 16. Disse forsenkede partier 27 er utformet slik at de rommer ovenfor støtteflen-sen beliggende deler 28 - fortrinnsvis såkalte skruehoder - av festeorganene 16, slik at delene 28 ikke stikker opp over slike anleggsflater 29 på støtteflensen 13 som silorganets 9 ramme 10 er beregnet å ligge an mot. Disse forsenkede partier 27 kan dannes ved at støtteflensen 13 er nedbøyd rundt om hullet 17, eller på annen egnet måte. De forsenkede partier 27 innebærer at silorganet 9 ikke belaster festeorganene 16 direkte, og dessuten at festeorganenes 16 deler 28 ikke kan slite istykker silorganets 9 ramme 10. The support flange 13 preferably has recessed parts 27 around each hole 17 for the fastening means 16. These recessed parts 27 are designed so that they accommodate parts 28 located above the support flange - preferably so-called screw heads - of the fastening means 16, so that the parts 28 do not protrude above such contact surfaces 29 on the support flange 13 against which the sieve member 9 frame 10 is intended to rest. These recessed parts 27 can be formed by the support flange 13 being bent down around the hole 17, or in another suitable way. The recessed parts 27 mean that the strainer member 9 does not load the fastening members 16 directly, and furthermore that the parts 28 of the fastening members 16 cannot tear into pieces the frame 10 of the strainer member 9.

Montasjeflensen 14 består fortrinnsvis at et profilorgan som er fast anbrakt på sideveggene 6 et stykke ovenfor bunnen 4, og som hensiktsmessig forløper i lukket form, eksempelvis som en lukket ramme, innvendig langs avløpsrennens 1 vegger, hvilket innebærer at profilorganet danner en fordelaktig for-sterkning til avløpsrennen 1. Profilorganet kan oppvise ett eller flere hull 17 for festeorganene 16 ved hver side av av-løpsrennen 1, og det er hensiktsmessig festet ved alle av-løpsrennens 1 fire sider 6. The mounting flange 14 preferably consists of a profile member which is firmly placed on the side walls 6 some distance above the bottom 4, and which appropriately extends in a closed form, for example as a closed frame, internally along the walls of the drainage channel 1, which means that the profile member forms an advantageous reinforcement to the drainage channel 1. The profile member can have one or more holes 17 for the attachment devices 16 on each side of the drainage channel 1, and it is appropriately attached to all four sides 6 of the drainage channel 1.

Montasjeflensen 14 består videre fortrinnsvis av et L-profil hvis ene ben 3 0 er nedoverrettet og festet ved avløpsrennens 1 sidevegg 6, og hvis andre ben 31 rager ut fra nevnte sidevegg 6, hvorved det fortrinnsvis danner rett vinkel med benet 30. The mounting flange 14 further preferably consists of an L-profile whose one leg 30 is directed downwards and attached to the side wall 6 of the drainage channel 1, and whose other leg 31 protrudes from said side wall 6, whereby it preferably forms a right angle with the leg 30.

Festeorganene 16 er hensiktsmessig anordnet slik i støtte-flensen 13 at de blir dekket av silorganets 9 ramme 10. Støt-teflensen 13 er hensiktsmessig like bred, eller noe bredere enn montasjeflensen 14, slik at støtteflensen 13 sett ovenfra dekker montasjeflensen 14, og klemflensens 12 ytre deler 15 har nedentil hensiktsmessig en skråkant 32 ved ytterkanten for å gi fordelaktig pasning til gulvbelegget 3. The fastening members 16 are suitably arranged in the support flange 13 in such a way that they are covered by the frame 10 of the strainer member 9. The support flange 13 is suitably as wide as, or somewhat wider than, the mounting flange 14, so that the support flange 13, seen from above, covers the mounting flange 14, and the clamping flange 12 outer parts 15 suitably have a bevelled edge 32 at the outer edge at the bottom to provide an advantageous fit to the floor covering 3.

Monteringen av den ovenfor beskrevne klemanordning skjer ved at man plasserer bæredelen 8 i avløpsrennen 1, skrur ned festeorganene 16 til klemflensen 12 ligger an mot gulvbelegget 3 med nødvendig trykk, hvoretter man til slutt plasserer silorganet 9 på støtteflensen 13. The assembly of the above-described clamping device takes place by placing the carrier part 8 in the drainage channel 1, screwing down the fastening members 16 until the clamping flange 12 rests against the floor covering 3 with the necessary pressure, after which the strainer member 9 is finally placed on the support flange 13.

Oppfinnelsesgjenstanden er ikke begrenset til det som er beskrevet ovenfor og som er vist på tegningene, men kan vari-ere innenfor rammen av de etterfølgende patentkrav. Som eksempel på alternativer som ikke er beskrevet nærmere, kan nevnes at avløpsrennen 1 kan være en annen type avløpsanord-ning for å lede bort vann fra gulv; avløpsrennen kan oppvise helt annen form enn den viste, og også bæredelen til en viss grad og/eller montasjeflensen og/eller silorganet kan oppvise annen form eller andre former enn de viste. The object of the invention is not limited to what is described above and which is shown in the drawings, but may vary within the scope of the subsequent patent claims. As an example of alternatives that are not described in more detail, it can be mentioned that the drainage channel 1 can be another type of drainage device to divert water away from the floor; the drainage channel may have a completely different shape than that shown, and also the support part to a certain extent and/or the mounting flange and/or the strainer may have a different shape or shapes than those shown.
