Description

i DK 172982 B1in DK 172982 B1

Den foreliggende opfindelse angår et kabinet, en beklædning eller eri.låge til el-tavle og af den i indledningen til krav 1 angivne art.The present invention relates to an enclosure, a cover or an electric switchboard door and of the kind specified in the preamble of claim 1.

I forbindelse med pladekapslede el-tavler anvendes ofte beklædninger og låger, der er 5 udformet som rektangulære, skålformede elementer, og som er fremstillet ved oppres-ning af stålplade, dvs. med frie kanter, der er beregnet til at vende indad mod sidedele af el-tavlen, og som oftest langs hele omkredsen af nævnte frie kanter er'forsynet med en form for tætningsliste.In the case of plate-enclosed electric panels, cladding and doors, which are formed as rectangular, bowl-shaped elements, are often used which are made by steel plate reinforcement, ie. with free edges intended to face inwards towards the side portions of the switchboard, and usually along the entire circumference of said free edges are provided with a form of sealing strip.

10 En kendt type tætningsliste til låger for el-tavler består af en gummi- eller plastliste, der har et i hovedsagen C-formet tværsnit, og som er beregnet til at fastgøres til en fri kant af lågen.10 A known type of sealing strip for doors for electrical panels consists of a rubber or plastic strip having a substantially C-shaped cross section and which is intended to be attached to a free edge of the door.

I praksis har det vist sig problematisk at opnå en tilstrækkelig god og; vedblivende be-15 fæstigelse mellem tætningslisten og nævnte frie kanter henholdsvis tilstrækkelig god tætning mod sidedele af el-tavlen.In practice it has proved problematic to obtain a sufficiently good and; continued attachment between the sealing strip and said free edges, respectively, sufficiently good sealing against side portions of the electrical board.

Opfindelsen har til formål at angive et ny og forbedret kabinet, beklædping eller låge til el-tavle af den indledningsvis nævnte type, og som ved hjælp af enkle foranstaltninger 20 gør det muligt at opnå vedblivende og mere effektiv tætning af kabinetter, beklædninger eller låger til el-tavler.The invention has for its object to provide a new and improved cabinet, covering or door for electrical panels of the type mentioned in the introduction, which by means of simple measures 20 make it possible to obtain continuous and more effective sealing of cabinets, covers or doors for electric switchboards.

Kabinettet, beklædningen eller lågen til el-tavle ifølge opfindelsen er kendetegnet ved, at modstående frie kantdele af grundprofilen er indrettet til at indgribe i en langs nævnte 25 frie kantdel af nævnte vægdel udformet endeløs holdereces henholdsvis at omslutte en langs ydersidekanten af vægdelen udstående, endeløs ribbe. På enkel måde opnås herved et kabinet, en beklædning eller en låge til el-tavle med en tætningsliste, hvor indgrebet mellem den frie kantdel af vægdelen af kabinettet, beklædningen eller lågen, navnlig på grund af den udstående ribbe langs ydersidekanten af vægdelen danner en således for-30 længet "labyrint", at det bliver ekstraordinært svært for vand at trænge ind mellem ydersidekonturen af kantdelen og indersidekonturen af grundprofilen.The housing, panel or cover for the electrical board according to the invention is characterized in that opposite free edge portions of the basic profile are arranged to engage an endless holder section formed along said 25 free edge part or to enclose an endless projecting along the outer edge of the wall part, respectively. rib. In this way, a cabinet, a covering or a door for a panel with a sealing strip is obtained, whereby the engagement between the free edge part of the wall part of the cabinet, the covering or the door, in particular due to the protruding rib along the outer edge of the wall part, forms a extended "maze" that it becomes extraordinarily difficult for water to penetrate between the outer contour of the edge portion and the inside contour of the basic profile.

DK 172982 B1 2DK 172982 B1 2

Hensigtsmæssigt er kabinettet, beklædningen eller lågen ifølge opfindelsen udformet således, at nævnte ribbe af vægdelen har et tværsnit som en i hovedsagen retvinklet trekant, hvoraf en længste "katete" flugter med yderside af vægdelen, og hvoraf "hypotenusen" danner en yderside af ribben, der således har stigende højde i retning bort 5 fra den fri kantdel af vægdelen.Conveniently, the housing, cover or lid of the invention is designed such that said rib of the wall portion has a cross-section as a generally right-angled triangle, a longest "catheter" flush with the outside of the wall portion, and the "hypotenuse" forming an outside of the rib, thus having increasing height in the direction away from the free edge portion of the wall portion.

Og med særlig fordel kan tætningslisten være udformet således, at grundprofilen er integreret med den blødere listeprofildel, der f.eks. har form som en luftfyldt læbetætning.And with particular advantage, the sealing strip can be designed such that the base profile is integrated with the softer strip profile part which e.g. has the shape of an air-filled lip seal.

i 10 Alternativt kan tætningslisten være udformet således, at grundprofilen er integreret med den blødere listeprofildel, der f.eks. omfatter ydre indbyrdes parallelle profilspor, der ved anlæg mod en sidedel af en el-tavle danner en labyrint tætning.Alternatively, the sealing strip may be designed such that the base profile is integrated with the softer strip profile portion, e.g. comprises outer mutually parallel profile grooves which, upon abutment against a side portion of an electrical panel, form a maze seal.

Endelig kan tætningslisten eventuelt være udformet således, at grundprofilen omfatter en j 15 indvendig blødere tætningslistedel, der er placeret mellem den yderste frie kantdel af S vægdelen og bunden af indersidekonturen af grundprofilen.Finally, the sealing strip may optionally be formed such that the base profile comprises an inner softer sealing strip portion located between the outer free edge portion of the S wall portion and the bottom of the inner contour of the base profile.

Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken:- 20 Fig. 1 viser et delbillede - delvis i snit - af en udførelsesform for en tætningsliste til fastgørelse på en fremstående vægdel af et kabinet, en beklædning eller en låge ifølge opfindelsen, fig. 2 viser et delsnitbillede af en fri kantdel af en beklædning eller en låge til en 25 el-tavle eller en fri kantdel af en fremstående vægdel af et kabinet til en el-tavle, fig. 3 viser et delbillede - delvis i snit - af en beklædning eller en låge til en el-tavle, 30 DK 172982 B1 3 fig. 4 viser et delbillede - delvis i snit - af en dobbelt-tætning mellem en fremstående kantdel af en el-tavle og en beklædning eller en låge for el-tavlen, medens 5 fig. 5 viser et delbillede - delvis i snit - af en tætning mellem en fremstående, fri kantdel, f.eks. af en el.tavle, og en beklædning eller en låge.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail in connection with the drawing, in which: - FIG. 1 is a partial view, partly in section, of an embodiment of a sealing strip for attachment to a prominent wall portion of a cabinet, cladding or door according to the invention; FIG. 2 is a partial sectional view of a free edge portion of a cladding or cover for a 25 electrical board or a free edge portion of a projecting wall portion of a cabinet for an electrical panel; FIG. 3 shows a partial view - partly in section - of a cover or door for a switchboard, FIG. 4 shows a partial view - partly in section - of a double seal between a protruding edge part of an electrical panel and a covering or cover of the electrical panel, while FIG. 5 shows a partial view - partly in section - of a seal between a prominent free edge portion, e.g. of an electrical board, and a cladding or a door.

Den i fig. I viste tætningsliste 2 består af en grundprofil 4 og en dermed integreret Iiste-profildel 6, der har form som en i hovedsagen læbeformet, luftfyldt slange, der langs en 10 yderside 8 er beregnet til at ligge an mod en sidedel af en el-tavle.The FIG. The sealing strip 2 shown consists of a basic profile 4 and an integral molded profile part 6, which is in the form of a generally lip-shaped, air-filled hose which is intended to abut against a side part of an electrical board along a 10 outer side 8. .

Grundprofilen 4 er indrettet til at fastgøres omkring en fri kantdel 10 af en udragende vægdel 12 eller en fremstående kantdel (fig. 2) af en el-tavle, beklædning eller låge 13 (fig. 3), idet grundprofilen 4 ved indersiden er udformet med en holdelistedel 14 med 15 tværsnit som en pil, dvs. med en langsgående, fremspringende -indvendig holdekant 16, der er beregnet til at indgribe i en holdereces 18, der er udformet parallelt med den fri kantdel 10 af vægdelen 12 i indersidevæggen af beklædningen eller lågen 13.The base profile 4 is arranged to be secured around a free edge part 10 of a protruding wall part 12 or a protruding edge part (Fig. 2) of an electric panel, cladding or door 13 (Fig. 3), the base profile 4 being formed on the inside with a holding strip portion 14 having 15 cross sections as an arrow, i. having a longitudinal projecting inner holding edge 16 intended to engage a holding recess 18 formed in parallel with the free edge portion 10 of the wall portion 12 of the inside wall of the casing or cover 13.

Grundprofilen 4 er ved modsatte yderside udformet med en profilering 20 (fig. 1) med 20 en ydre indadrettet gribelistedel 22, der er indrettet til at gribe omkring en langs ydersiden af vægdelen 12 udstående ribbe 24, der forløber parallelt med den fri kantdel 10 af vægdelen 12, og som har et overvejende trekantet tværsnit, dvs. har størst højde i retning bort fra den frie kantdel 10 af vægdelen 12.The base profile 4 is formed at opposite exterior with a profiling 20 (Fig. 1) with 20 an outer inwardly gripping molding portion 22 adapted to grip a rib 24 extending along the outside of the wall portion 12 extending parallel to the free edge portion 10 of the wall portion 12 and having a predominantly triangular cross section, i. has the greatest height in the direction away from the free edge part 10 of the wall part 12.

25 Ved ydersiden af vægdelen 12 omfatter ribben 24 en vægdel 26, der i hovedsagen står vinkelret på vægdelen 12, og som medvirker til at fastholde gribelistedelen 22 på en sådan måde, at der desuden opnås en ekstraordinær basistætning, fordi vandet dels ikke er tilbøjelig til at forsere den udad-førende vægdel 26 og dels får en længere vej gennem den "labyrint", der er dannet mellem ydersidekonturen af kantdelen 10 af vægdelen 12 30 og indersidekonturen af grundprofilen 4.25 At the outside of the wall portion 12, the rib 24 comprises a wall portion 26 which is generally perpendicular to the wall portion 12 and which helps to retain the gripper molding portion 22 in such a way that an extraordinary base seal is also obtained because the water is partly not inclined to forcing the outwardly extending wall portion 26 and, in part, a longer path through the "maze" formed between the outer contour of the edge portion 10 of the wall portion 12 30 and the inside contour of the base profile 4.
