Abstract

There is disclosed a manhole cover frame (8) with self-locking function of the cover (2), the manhole cover frame (8) comprising a number of locking means arranged to interact with complementarily shaped locking means of the cover, where the said locking means of the manhole cover frame are constituted by a number of curved, resilient locking members (12) which are formed in an internal side wall (10) of the manhole cover frame (8), and which at a free outer end (16) are designed with inwardly protruding locking projections (18), and that the complementarily shaped locking means of the cover are constituted by a corresponding number of upwardly open lateral recesses (14) having a lower locking face (6) which is arranged to interact with the said locking projections. By means of simple measures is hereby achieved an improved and more operation-friendly locking function which furthermore, due to the resilient locking members being situated in the side of the manhole cover frame instead of as previously normally in the cover, will be less exposed to being damaged in use. Furthermore, it will be regarded as an advantage that the dead weight of a cover according to the invention may be minimised, i.e. easier to handle.

Den foreliggende opfindelse angår en kloakbrøndkarm med selvlåsende funktion af dæksel af den i indledningen til krav 1 angivne art.The present invention relates to a sewer well casing with a self-locking function of cover of the kind specified in the preamble of claim 1.

Kloakbrøndkarme og brønd- eller mandehulsdæksler fremstilles - uanset størrelsen -5 sædvanligvis af støbejem. I de fleste tilfælde vil dækslets egenvægt være så stor, at dækslet under normale forhold ikke åbnes af uautoriserede personer. I praksis har det imidlertid vist sig at være et alvorligt problem, at selv meget store og tunge brønd- eller mandehulsdæksler kan blive suget op ved passage af store køretøjer. Derfor stilles der fra vejmyndighedernes side i praksis oftest krav om en forni for låsefunktion mellem 10 dæksel og kloakbrøndkarm. Og af hensyn til forbedret sikkerhed arbejdes der oftest med selvlåsende kloakbrønd- eller mandehulsdæksler.Sewer well casings and well or manhole covers are manufactured - regardless of size -5 usually of cast iron. In most cases the weight of the cover will be so large that under normal conditions the cover will not be opened by unauthorized persons. In practice, however, it has proved to be a serious problem that even very large and heavy well or manhole covers can be sucked up when passing large vehicles. Therefore, in practice, the road authorities are most often in demand for a lock for locking function between 10 covers and sewer well casing. And for the sake of improved security, self-locking sewer well or manhole covers are most often used.

Selvlåsende kloakbrønd- eller mandehulsdæksler kendes i mange forskellige udformninger såsom fra DK-B-154 519, CH-A-448 917, SE-B-436 050 samt GB-A-2 085 946.Self-locking sewer well or manhole covers are known in many different designs such as from DK-B-154 519, CH-A-448 917, SE-B-436 050 and GB-A-2 085 946.

15 Fælles for disse kendte dæksler er imidlertid, at de er besværlige at betjene og oftest kræver anvendelse af specialværktøj for at udløse dækslets fj ederpåvirkede lås.15 Common to these known covers, however, is that they are difficult to operate and most often require the use of specialized tools to release the cover's spring-loaded locks.

Opfindelsen har til formål at angive en forbedret kloakbrøndkarm med selvlåsende funktion af dæksel af den indledningsvis nævnte art, og som ved hjælp af enkle foran-20 staltninger gør låsefunktionen mere optimal og betjeningen lettere.The invention has for its object to provide an improved sewer well casing with self-locking function of cover of the kind mentioned above, and which by simple means makes the locking function more optimal and the operation easier.

Kloakbrøndkarmen ifølge opfindelsen er kendetegnet ved, at nævnte låseorganer af klo-akbrøndkarmen udgøres af et antal buede, fjerdrende låsearme, der er udformet i en indvendig sidevæg af kloakbrøndkarmen, og som ved en fri yderende er udformet med 25 indadragende låsefremspring, og at nævnte komplementært udformede låseorganer af dækslet udgøres af et tilsvarende antal opadtil åbne sideudskæringer, der har en nedre låseflade, der er indrettet til at samvirke med nævnte låsefremspring. Ved hjælp af enkle foranstaltninger opnås herved en forbedret og mere betjeningsvenlig låsefunktion, der yderligere som følge af, at de § edrende låsearme findes i siden af kloakbrøndkarmen 30 - fremfor som hidtil normalt i dækslet - vil være mindre udsat for at blive beskadiget ved brag. Desuden vil det anses for en fordel, at egenvægten af et dæksel ifølge opfindelsen kan minimeres, dvs. være lettere at håndtere.The sewer well casing according to the invention is characterized in that said locking means of the sewer well casing are constituted by a plurality of curved, resilient locking arms formed in an inner side wall of the sewer well casing, which is formed at a free outer end with 25 inwardly extending locking protrusion. formed locking means of the cover are constituted by a corresponding number of upwardly open side cuts having a lower locking surface adapted to cooperate with said locking projection. By means of simple measures, an improved and more user-friendly locking function is obtained, which, furthermore, due to the fact that the locking arms located on the side of the sewer well frame 30 - rather than hitherto normal in the cover - will be less susceptible to damage by bursting. In addition, it will be considered an advantage that the intrinsic weight of a cover according to the invention can be minimized, i.e. be easier to handle.

Hensigtsmæssigt kan kloakbrønkarmen ifølge opfindelsen være således udformet, at den ved ydersiden af nævnte buede, fjedrende låsearme og i afstand derfra har en buet ydervægdel, således at der dannes et buet hulrum bagved de fjedrende låsearme. På 5 enkel måde tilsikres herved tillige optimal funktion af de fjedrende låsearme, idet de buede hulrum kun er åbne nedadtil, dvs. at der ikke trænger sand og grus ind bag og blokere funktionen aflåsearmene.Conveniently, the sewer well casing according to the invention may be designed such that it has at the exterior of said curved, resilient locking arms and at a distance therefrom an arched outer wall portion so as to form a curved cavity behind the resilient locking arms. In a simple way, this also ensures optimal function of the resilient lock arms, the curved cavities being only open downwards, ie. that sand and gravel do not penetrate behind and block the function of the locking arms.

For at opnå en mere optimal fordeling af låsekraften kan kloakbrøndkarmen ifølge op-10 findelsen med fordel være således udformet, at den er udformet med to diametralt overfor hinanden placerede fjedrende låsearme. Herved opnås desuden en god symmetri af låsefunktionen, således at dækslet ikke kæntre ved håndteringen.In order to achieve a more optimal distribution of the locking force, the sewer well casing according to the invention may advantageously be designed to be formed with two diametrically opposite resilient locking arms. This also ensures a good symmetry of the locking function, so that the cover does not stick when handling.

Opfindelsen angår desuden et dæksel til brug i forbindelse med kloakbrøndkarmen iføl-15 ge opfindelsen, hvilket dæksel er kendetegnet ved, at det er udformet med to af nævnte sideindskæringer, der er placeret diametralt overfor hinanden langs dækslets periferi.The invention further relates to a cover for use in connection with the sewer well casing according to the invention, which is characterized in that it is formed with two of said side notches located diametrically opposite one another along the periphery of the cover.

Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, på hvilken: 20 Fig. 1 viser et plant billede af en udførelsesfonn for et dæksel med selvlåsende funktion til kloakbrøndkarm eller mandehul ifølge opfindelsen - set fra oven, fig. 2 viser et sidesnitbillede af en udførelsesfonn for en kloakbrøndkarm med selvlå sende funktion ifølge opfindelsen, 25 fig. 3 viser et ovenbillede - delvis i snit - af den i fig. 2 viste kloakbrøndkarm ifølge opfindelsen, og fig. 4 viser et forstønet delsnitbillede til illustration af låsefunktionen mellem kloak-30 brøndkarm og brønddæksel ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in greater detail with reference to the accompanying drawings, in which: FIG. 1 is a plan view of an embodiment of a cover with self-locking function for sewer well casing or manhole according to the invention - seen from above; FIG.

Det i fig. 1 viste kloak- eller mandehulsdæksel 2 er udformet med to diametrale sideindskæringer 4, hvis sideprofil, der omfatter en nedre låseflade 6, ses mere tydeligt i fig. 4.The FIG. 1, the sewer or manhole cover 2 shown is formed with two diametrical side notches 4, the side profile of which includes a lower locking surface 6 is more clearly seen in FIG. 4th

En udførelsesform for en kloakbrøndkarm 8, der er vist i fig. 2 og 3, omfatter i en sidevæg 10 to buede, fjedrende låsearme 12, der ved 14 er forbundet med sidevæggen 10, og 5 som ved frie yderender 16 er udformet med indadragende låsefremspring 18, der jf. fig.An embodiment of a sewer well casing 8 shown in FIG. 2 and 3, in a side wall 10 comprises two curved, resilient locking arms 12, which at 14 are connected to the side wall 10, and 5 which are formed at free outer ends 16 with inwardly extending locking projections 18, cf.

4 samvirker med den nedre låseflade 6 af sideudskæringeme 4 af dækslet 2.4 cooperates with the lower locking surface 6 of the side cut-outs 4 of the cover 2.

I fig. 4 er desuden illustreret, hvordan den selvlåsende låsefunktion mellem kloakbrønd-karmen 8 og dækslet 2 let udløses ved hjælp af en yderende af en betjeningsstang 20 ved 10 tilbagepresning af låsefremspringene 18, således at de buede, fjedrende låsearme 12 svinges bagud i et buet hulrum 22 bagved låsearmene 12. Dette hulrum 22, der har ydervægge 24 og 26, har netop til formål at sørge for, at funktionen af de fjedrende låseaime 12 ikke forstyrres af indstrømmede materiale (sten og sand etc.), hvorfor hulrummet 22 kun er åbent nedadtil.In FIG. 4 is further illustrated how the self-locking locking function between sewer well casing 8 and cover 2 is easily triggered by an end of an actuating rod 20 at 10 for back-pressing the locking projections 18 so that the curved, resilient locking arms 12 are pivoted rearwardly in a curved cavity 22 behind the locking arms 12. This cavity 22, which has outer walls 24 and 26, is intended precisely to ensure that the function of the resilient locking arms 12 is not disturbed by the inflowed material (stones and sand etc.), so that the cavity 22 is only open downwards .
