Den foreliggende opfindelse angår en lås til en dør til et fordelings- eller koblingsskab eller et andet rum til elektrisk udrustning, hvor døren er ophængt ved hjælp af hængsler i en dørramme, og hvor der ved den side af dør-5 rammen, som er beliggende overfor dørhængslerne, er fastgjort en liste, hvis længde er af samme størrelsesorden som dørens højde, på en sådan måde, at listen er svingelig mellem en fri stilling, i hvilken døren kan åbnes, og en låsestilling, i hvilken dørens frie langsgående kant dæklo kes af listen.BACKGROUND OF THE INVENTION The present invention relates to a door lock for a distribution or switch cabinet or other electrical equipment compartment in which the door is suspended by hinges in a door frame and at the side of the door frame located opposite to the door hinges, a strip, the length of which is the same size as the height of the door, is fixed in such a way that the list is pivotal between a free position in which the door can be opened and a locking position in which the free longitudinal edge of the door is closed. of the list.
Ved åbne lysbuer i kapslede fordelings- og koblingsanlæg kan der opstå store trykstigninger. Eksempelvis har man målt tryk på 3-4 tons pr. m på døren til et fordelings- og koblingsskab, i hvilket en lysbue på 4o kA har 15 brændt under et sektand. Skabsdøren og dens låsemekanisme skal være så mekanisk stabile, at de ikke giver efter for disse høje tryk. Der må heller ikke dannes sprækker rundt om døren af en sådan størrelse, at udstrømmende varme gasser kan skade driftspersonalet.Open arcs in enclosed distribution and coupling systems can cause large pressure increases. For example, pressures of 3-4 tonnes per hour have been measured. m on the door of a distribution and switch cabinet, in which an arc of 4o kA has 15 burned under one section. The cabinet door and its locking mechanism must be so mechanically stable that they do not yield to these high pressures. Also, no cracks should be formed around the door of such size that outflowing hot gases can harm the operating personnel.
2o En lås af den indledningsvis angivne art er kendt fra svensk patentskrift nr. 356.785. Ved den kendte konstruktion er lodrette lister af vinkeljern fastgjort ved hjælp af hængselsled til forkanten af dørrammen på hver side af døren. Dørbladet er permanent fastskruet mod inder-25 siden af den ene af disse lister. Til låsning af den lukkede dør klappes den anden liste ind over den frie dørkant og fastskrues til denne. Denne konstruktion har den ulempe, at låsningen af.døren er omstændelig og tidskrævende, hvilket medfører risiko for, at skruerne ikke tilspændes or-3o dentligt, eksempelvis på grund af tidmangel eller forglemmelse hos betjeningspersonalet, med manglende personsikkerhed som resultat.A lock of the kind initially provided is known from Swedish Patent Specification No. 356,785. In the known construction, vertical moldings of angular iron are secured by hinge joints to the leading edge of the door frame on each side of the door. The door leaf is permanently screwed to the inner side of one of these moldings. To lock the closed door, fold the second list over the free door edge and screw into it. This construction has the disadvantage that the locking of the door is tedious and time-consuming, which results in the risk that the screws are not tightened properly, for example due to lack of time or forgetfulness of the operating staff, with a lack of personal safety as a result.
Formålet med den foreliggende opfindelse er at tilvejebringe en lås til døre til fordelings- og koblingsska-35 be af den omhandlede art, og som er enklere at betjene og giver større personsikkerhed end tidligere kendte udførelser. Ifølge opfindelsen opnås dette ved, at der på listen er fastgjort en låserigel, som er indrettet til at samvirke 2 146890 med et på døren fastgjort spærreorgan, og at listen på sin mod døren vendende side har en tap, som er indrettet til i den nævnte låsestilling at indgribe i et hul i døren. Ved hjælp af låseriglen og det på døren fastgjorte spærreorgan 5 fås der en enkel stabil og hurtig manøvrerbar mekanisme til låsning af døren. Sammenholdelsen af skabets forside forstærkes yderligere ved hjælp af den på listen anbragte tap, som i listens låsestilling står i indgreb med døren og derved forhindrer udbugtning af denne ved indre overtryk lo i skabet.The object of the present invention is to provide a lock for doors for distribution and coupling switches of the kind in question, which are easier to operate and provide greater personal security than prior art designs. According to the invention, this is achieved by attaching to the list a locking bolt adapted to cooperate with a locking means fixed on the door and the tab on its side facing the door has a tab arranged in the said locking position to engage in a hole in the door. By means of the locking bolt and the locking means 5 fixed on the door, a simple stable and fast maneuverable mechanism for locking the door is obtained. The fastening of the front of the cabinet is further enhanced by the tabs on the molding, which in the locking position of the molding engage with the door, thereby preventing the bending of the molding by internal overpressure in the cabinet.
En særlig enkel låsekonstruktion opnås ved en videre udvikling ifølge opfindelsen ved, at låseriglen er svinge-ligt lejret på en forlængelse af tappen, som strækker sig gennem listen.A particularly simple locking structure is achieved by a further development according to the invention in that the locking bolt is pivotally mounted on an extension of the pin extending through the frame.
15 Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, hvor fig. 1 viser et billede forfra af et fordelings- og koblingsskab forsynet med en udførelsesform for låsen ifølge opfindelsen, 2o fig. 2 og 3 den nærmere udførelse af låsen, idet fi gurerne viser snit efter linierne henholdsvis A-A og B-B i fig. 1.The invention will now be explained in more detail with reference to the drawing, in which fig. 1 is a front view of a distribution and switch cabinet provided with an embodiment of the lock according to the invention; FIG. 2 and 3 show the detailed embodiment of the lock, the figures showing sections along the lines A-A and B-B in FIG. First
Det viste fordelings- og koblingsskab er forsynet med en dør 1, som ved hjælp af hængsler 2 er ophængt på 25 den ene sidestolpe i en dørramme 3. På rammen 3's modsatte sidestolpe er der ved hjælp af hængsler 4 fastgjort en liste 5, som udgøres af et til L-form bukket profil, som er lige så langt som døren. Midt på listen 5 er der fastgjort en som håndtag udformet låserigel 6, der er dreje-3o lig om en vandret tap 7. Låseriglen 6 er indrettet til at samvirke med et på døren 1 fastgjort spærreorgan 8.The distribution and coupling cabinet shown is provided with a door 1, which by means of hinges 2 is suspended on one side pillar of a door frame 3. On the opposite side pillar of frame 3, a list 5 which is constituted by hinges 4 is attached. of an L-shaped curved profile that is as far as the door. In the middle of the molding 5 is a locking bolt 6 which is arranged as a handle, which is rotatable about a horizontal pin 7. The locking bolt 6 is arranged to cooperate with a locking means 8 fixed on the door 1.
. Låsen åbnes med et håndgreb ved, at låseriglen 6 løftes opad fra det på døren 1 værende spærreorgan 8, hvorefter låseriglen og dermed også listen 5 drejes udad til 35 den med stiplede linier i fig. 2 viste stilling. Døren 1 kan nu åbnes.. The lock is opened with a handle by lifting the locking bolt 6 upwards from the locking member 8 on the door 1, after which the locking bolt and thus also the strip 5 is turned outwards to the dotted lines in FIG. 2. The door 1 can now be opened.
Den på midten af listen 5 værende tap 7 rager frem på indersiden af listen 5 og vil ved låst dør gå ind i et 146890 3 til stiften afpasset hul i døren '1. Derved fås en ekstra sikkerhed for, at skabet holdes sammen ved en eventuel lysbue i skabet.The tab 7 located at the center of the list 5 protrudes on the inside of the list 5 and will, at the locked door, enter a hole adapted to the pin in the door '1. This provides extra security for the cabinet being held together by any arc in the cabinet.
