Description

DK 172425 B1DK 172425 B1

Den foreliggende opfindelse angår en anordning ved rammer til låg eller dæksler til brønde eller kummer, hvor låget eller dækslet har cirkelrundt omrids og er udstyret med mindst én fjedrende indretning til at låse og sikre låget eller dækslet 5 mod utilsigtet opløftning. Et eksempel på en sådan låseindretning er vist i NO 157.429.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for frames or covers for wells or basins, wherein the lid or cover has a circular outline and is provided with at least one resilient device for locking and securing the lid or cover 5 against accidental lifting. An example of such a locking device is shown in NO 157.429.

En ulempe ved cirkelrunde brøndlåg og lignende dæksler, som er anbragt i vejbaner, er, at de under påvirkning af passerende trafik kan rotere i rammen, hvilket er særligt uhel-10 digt i de tilfælde, hvor der rundt om lågets omkreds er anbragt en pakning, idet rotationen af låget kan føre til, at pakningen vrides ud af position og dermed mister sin effektivitet. Desuden medfører en sådan rotation større slitage og dermed kortere levetid for pakningen.A disadvantage of circular wells and similar covers arranged in roadways is that they can rotate in the frame under the influence of passing traffic, which is particularly disadvantageous in cases where a gasket is arranged around the perimeter of the lid. , since the rotation of the lid can cause the gasket to be twisted out of position and thus lose its effectiveness. Furthermore, such a rotation results in greater wear and thus shorter life of the gasket.

15 Denne ulempe er søgt overvundet ved den foreliggende opfindelse, hvor det særegne består i de træk, som fremgår af patentkravet.This disadvantage has been sought to be overcome by the present invention, where the specificity consists in the features which appear in the claim.

Der kendes ganske vist låg eller dæksler, som ikke kan drejes i karmen, idet låget eller dækslet, henholdsvis rammen er 20 udført med et ikke-cirkulært omrids, jfr. fx NO 57.048. I modsætning til disse tidligere kendte udførelsesformer vil låget eller dækslet i overensstemmelse med den foreliggende opfindelse kunne anbringes i rammen med en vilkårlig orientering og alligével, eventuelt efter en begrænset drejebevæ-25 gelse, blive spærret mod ukontrolleret drejning.Certain lid or covers are known which cannot be rotated in the frame, the lid or cover, respectively the frame being 20 having a non-circular outline, cf. eg NO 57.048. In contrast to these prior art embodiments, the lid or cover of the present invention may be placed in the frame with any orientation and, possibly, after a limited pivotal movement, be locked against uncontrolled rotation.

Opfindelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, som i udsnit viser et snit gennem en brøndramme med tilhørende låg med låseindretning.The invention will be described in more detail below with reference to the drawing, which in section shows a section through a well frame with associated lid with locking device.

På tegningen betegner 1 skørtet på en brøndramme 2, medens 3 30 betegner et brøndlåg, som under mellemlæg af en pakning 4, hviler på en skulder 5 i rammen 2.In the drawing, 1 denotes the skirt of a well frame 2, while 3 30 denotes a well lid which rests on a shoulder 5 of the frame 2 under the intermediate of a gasket 4.

2 DK 172425 B1 Til låsning af låget 3 i forhold til rammen 2, er der anbragt en fjedrende låseindretning med en slå 6, som kan bevæges vinkelret på lågomkredsen for at samvirke med rammeskørtet 1, fx som vist ved at gribe ind under en rundtgående vulst 7 på 5 skørtet, hvorved låget er sikret mod utilsigtet opløftning. For at hindre, at låget 3 skal rotere i rammen 2, er der på rammeskørtet 1 anbragt en spærreindretning, som kan være i form af en fordybning i skørtet eller i form af et par vertikale ribber 8. På slåen 6 er der en knast eller et vortelig-10 nende fremspring 9, der er indrettet til at samvirke med spærreindretningen 8. Rammen er hensigtsmæssigt udformet med flere, perifert adskilte spærreindretninger af den angivne type.2 DK 172425 B1 To lock the lid 3 with respect to the frame 2, a resilient locking device is provided with a punch 6 which can be moved perpendicular to the lid circumference to cooperate with the frame skirt 1, for example as shown by engaging under a circumferential bead. 7 of 5 skirt, thereby securing the lid against accidental lifting. In order to prevent the lid 3 from rotating in the frame 2, a locking device is arranged on the frame skirt 1 which can be in the form of a depression in the skirt or in the form of a pair of vertical ribs 8. On the beating 6 there is a knob or an annular protrusion 9 adapted to cooperate with the locking device 8. Conveniently, the frame is formed with a plurality of peripherally spaced locking devices of the specified type. 15 Anordning ved ramme til brøndlåg eller dæksel, hvor låget eller dækslet har et cirkelrundt omrids og er udstyret med mindst én fjedrende indretning til at låse eller sikre låget eller dækslet mod utilsigtet opløftning, kendetegnet ved, at rammen (2) på sit skørt (1) er 20 udstyret med et antal spærreindretninger (8) i form af fordybninger i skørtets indervæg eller aksialt ragende ribber (8) på skørtets indervæg, hvilke spærreindretninger er indrettet til at samvirke med den fjedrende låseindretning (6, 9. på låget (3) eller dækslet for at hindre rotation af låget 25 i rammen.Device by frame for well lid or cover, wherein the lid or cover has a circular outline and is provided with at least one resilient device for locking or securing the lid or cover against unintentional lifting, characterized in that the frame (2) on its skirt (1 ) is provided with a plurality of locking devices (8) in the form of recesses in the inner wall of the skirt or axially projecting ribs (8) on the inner wall of the skirt, which locking devices are adapted to cooperate with the resilient locking device (6, 9. on the lid (3)). or the cover to prevent rotation of the lid 25 in the frame.
