Description
8006028-8 Kända lâsanordningar för brunnslock har exempelvis inneburit att looken har försetts med hakar, som med bajonettgrepp bringas att samverka med vid brunnsringen anordnade komplemen- tära hakar. Ytterligare exempel utgörs av låskolvanordningar, som från lockets översida bringas att löpa in i för ändamålet gjorda urtagningar vid brunnsringen. I praktiken har de kända låsanordningarna icke fått någon utbredd användning, vilket dels torde bero på den komplicerade konstruktionen, dels på grund av att låsmekanismen har satts ur funktion på grund av rostangrepp eller ansamling av smuts. 8006028-8 Known locking devices for manhole covers have meant, for example, that the look has been provided with hooks, which are brought into co-operation with bayonet grips with complementary hooks arranged at the well ring. Further examples are locking piston devices, which from the upper side of the lid are caused to run into recesses made for the purpose at the well ring. In practice, the known locking devices have not been widely used, which is partly due to the complicated construction, and partly due to the locking mechanism being deactivated due to rust attack or accumulation of dirt.
Med en låsanordning enligt föreliggande uppfinning åstadkoms en konstruktion, som väl fyller de krav som kan ställas beträffande enkelt montage och demontage, samtidigt som huvud- kravet på effektiv låsning uppfylls.With a locking device according to the present invention, a construction is achieved which well meets the requirements that can be set regarding easy assembly and disassembly, at the same time as the main requirement for effective locking is met.
För att uppnå dessa syften har uppfinningen de i de efter- följande patentkraven angivna särdragen.To achieve these objects, the invention has the features set forth in the following claims.
Uppfinningen kommer i det följande att närmare beskrivas i anslutning till ritningen, varå ~ Fig. 1 visar ett vertikalt snitt genom en periferidel av locket intill brunnskanten, och Fig¿ 2 visar ett snitt enligt linjen A - A i fig. 1.The invention will be described in more detail below in connection with the drawing, in which Fig. 1 shows a vertical section through a peripheral part of the lid next to the well edge, and Fig. 2 shows a section along the line A - A in Fig. 1.
Runt ett brunnslocks 1 periferi är ett antal kilspår 2 anordnade.Around a periphery of a manhole cover 1 a number of keyways 2 are arranged.
Varje kilspår är utformat med en kilbana 5, vars utsträckning i periferiell led begränsas av två kilspårsgavlar 4a, 4b. Kilbanan 5 lutar ut mot lockets 1 periferi, så att den tillsammans med brunnsringens 5 inneryta 6 bildar ett nedåt smalnande spår. En centralt belägen urtagning 7, vars ändamål kommer att framgå av det följande, är upptagen i kilspåret 2 och delar kilbanan 5 i två delar.Each keyway is formed with a keyway 5, the extent of which in the circumferential direction is limited by two keyway ends 4a, 4b. The keyway 5 slopes out towards the periphery of the lid 1, so that together with the inner surface 6 of the well ring 5 it forms a downwardly tapering groove. A centrally located recess 7, the purpose of which will be apparent from the following, is accommodated in the keyway 2 and divides the keyway 5 into two parts.
För låsning av locket 1 mot brunnsringen 5, utnyttjas en låskropp 8006028-8 i form av en rulle 8. Låskraft erhålles då låskroppen 8 placeras mellan brunnsringens 5 inneryta 6 och kilbanan 5 samt pressas eller slås ned tills viss initialspänning uppstår. Vid rörelse uppåt av locket 1 rullar låskroppen ned samtidigt som, genom kilbanornas 3 lutning, utrymmet för låskroppen 8 minskar, varvid läskraften drastiskt ökar, även om brunnsringens 5 inneryta 6 har släppníng enligt fig. 1.For locking the lid 1 against the well ring 5, a locking body 8006028-8 is used in the form of a roller 8. Locking force is obtained when the locking body 8 is placed between the inner surface 6 of the well ring 5 and the keyway 5 and pressed or knocked down until a certain initial tension arises. When the lid 1 moves upwards, the locking body rolls down at the same time as, due to the inclination of the keyways 3, the space for the locking body 8 decreases, whereby the reading force drastically increases, even if the inner surface 6 of the well ring 5 has release according to Fig. 1.
För att förhindra att låskroppen 8 faller ned i brunnen, om locket 1 läggs excentriskt i en brunn med max-mått, är varje kilbana 3 i nederänden utformad med en vulst 9. Denna vulst har en sådan vinkel mot låskroppen 8, att låskroppen förs upp till rätt läge för montage, då locket centreras i brunnen.To prevent the locking body 8 from falling into the well, if the lid 1 is placed eccentrically in a well of maximum dimensions, each keyway 3 at the lower end is formed with a bead 9. This bead has such an angle to the locking body 8 that the locking body is raised to the correct position for mounting, when the lid is centered in the well.
Kilspårens 2 gavlar 4a, 4b har tre funktioner: - Förstärkning av kilbanorna 5 - Förhindrar låskroppen 8 att falla ur läge - Utgör styrning då locket 1 placeras på brunnen.The ends 4a, 4b of the keyway grooves 2 have three functions: - Reinforcement of the keyways 5 - Prevents the locking body 8 from falling out of position - Forms a guide when the cover 1 is placed on the well.
Montage och demontage kan ske med ett enkelt verktyg, t ex ett spett, som vid montage används för att slå ned låskroppen. Vid demontage förs qqäiæms ände upp i urtagningen 7 och låskroppen kan sålunda bändas loss.Assembly and disassembly can be done with a simple tool, such as a skewer, which is used during assembly to lower the locking body. During disassembly, the end of the qqäiäm is moved up into the recess 7 and the locking body can thus be pryed loose.
Med anordningen enligt uppfinningen erhålls bästa tänkbara korrosionssäkerhet, eftersom enbart gjutjärn kommer till an- vändning och risken för spänningskorrosion inte förefinns.With the device according to the invention, the best possible corrosion safety is obtained, since only cast iron is used and the risk of stress corrosion does not exist.
