Description
LåseanordningLocking device
Oppfinnelsen angår en låseanordning for en dørThe invention relates to a locking device for a door
til et stillverksskap eller et annet rom for elektrisk utrustning. to a silencer cabinet or other room for electrical equipment.
Ved åpne lysbuer i kapslede stillverk kan det oppstå store trykkøkninger. Eksempelvis har man målt trykk på. 3-4 tonn pr. m på døren til et stillverksskap i hvilket en lysbue på 40 kA har brent i ett-sekund. Skapdøren og dennes låseanordning må være så mekanisk stabile at de ikke gir etter for disse høye trykk. Det må heller ikke dannes sprekker rundt døren av en sådan størrelse at utstrømmende varme gasser kan skade driftspersonalet. In the case of open arcs in encapsulated stills, large pressure increases can occur. For example, pressure has been measured on 3-4 tonnes per m on the door of a silencer cabinet in which a 40 kA arc has burned for one second. The cabinet door and its locking device must be so mechanically stable that they do not yield to these high pressures. Cracks must also not form around the door of such a size that escaping hot gases could injure the operating staff.
En hittil vanlig benyttet utførelse av still-verkslås utgjøres av tre MlO-skruer som manøvrerés med et løst håndtak. Denne manøvrering er omstendelig og tidkrevende, hvilket medfører fare for at skruene ikke tiltrekkes tilstrek-kelig, eksempelvis på grunn av tidsmangel eller glemsomhet hos betjeningspersonalet, med manglende personsikkerhet som resultat. A hitherto commonly used version of the still mechanism lock consists of three MlO screws which are maneuvered with a loose handle. This maneuvering is laborious and time-consuming, which entails the risk that the screws are not tightened sufficiently, for example due to lack of time or forgetfulness on the part of the operating staff, with a lack of personal safety as a result.
Formålet med oppfinnelsen er å tilveiebringe en låseanordning for dører for stillverksskap og liknende, -som er enklere å betjene og gir større personsikkerhet enn tid-ligere kjente utførelser. Dette oppnås'ved de foranstaltninger som er angitt i den karakteriserende del av patentkrav 1. The purpose of the invention is to provide a locking device for doors for still work cabinets and the like, which is easier to operate and provides greater personal safety than previously known designs. This is achieved by the measures specified in the characterizing part of patent claim 1.
Oppfinnelsen skal beskrives nærmere i det følgende i forbindelse med et utførelseseksempel under henvisning til tegningen, der fig.. 1 viser et frontriss av et stillverksskap med låseanordning hvis utførelse fremgår•nærmere av fig. 2 og 3 som viser snitt etter linjene A - A hhv. B. - B på fig. 1. The invention will be described in more detail in the following in connection with an embodiment with reference to the drawing, where fig.. 1 shows a front view of a still work cabinet with a locking device, the embodiment of which can be seen in more detail from fig. 2 and 3 which show sections along the lines A - A respectively. B. - B in fig. 1.
Det viste stillverksskap er forsynt med en dørThe still work cabinet shown is equipped with a door
1 som ved hjelp av hengsler 2 er opphengt på den ene side-stolpei en dørramme 3. På rammens 3 motsatte sidestolpe er det ved hjelp av hengsler 4 festet en list 5 som utgjøres av en til L-form bøyd profil som er like lang som døren. Midt på listen 5 er festet en som håndtak utformet låsereile 6:"som er dreibar om en horisontal tapp 7. Låsereilen 6 er- innrettet til å samvirke med en på døren 1 festet sperre 8. 1 which, by means of hinges 2, is suspended on one side post of a door frame 3. On the opposite side post of the frame 3, a strip 5 is attached by means of hinges 4, which consists of a profile bent into an L shape, which is as long as the door. In the middle of the strip 5 is fixed a locking rail 6 designed as a handle, which can be turned about a horizontal pin 7. The locking rail 6 is arranged to cooperate with a latch 8 attached to the door 1.
Låseanordningen åpnes med et håndgrep ved at låsereilen 6 løftes oppover fra den på døren 1 tilstedeværende sperre 8, hvoretter låsereilen og dermed også listen 5 dreies ut-over til den med strekprikkede linjer på fig. 2 viste stilling. Døren 1 kan nå åpnes. ' , The locking device is opened with a hand grip by lifting the locking bolt 6 upwards from the latch 8 present on the door 1, after which the locking bolt and thus also the strip 5 is turned outwards to the one with dotted lines in fig. 2 shown position. Door 1 can now be opened. ' ,
Den på midten av listen 5 anordnede tapp 7The pin 7 arranged in the middle of the list 5
rager frem på innsiden av listen 5 og vil ved. låst dør gå inn X et til tappen tilpasset hull i døren 1. På denne måte opp-nås en ekstra sikkerhet for at skapet holdes sammen ved en. eventuell lysbue i skapet. protrudes inside the list 5 and will wood. locked door go in X a hole adapted to the pin in the door 1. In this way, extra security is achieved so that the cabinet is held together by a. possible arcing in the cabinet.
