Description

Oppfinnelsen angår en innretning for opplåsing av doré-r fra dorens utsj.de, hvilken dor er forsynt med postluke eller lignende, samt lås med på dorens innside anordnet vrider. The invention relates to a device for unlocking door locks from the outside of the door, which door is provided with a mail hatch or the like, as well as a lock with a twister arranged on the inside of the door.

Fra tidligere er d.et for opplåsing av sådanne dorer og låser benyttet såkalte "dorslynger" hvis bruksmåte består i at en av en sådan innretning omfattet snor- fra dorens utside bringes inn gjennom postluken eller lignende og vindes et passende antall ganger rundt låsvrideren en sådan vei at et etterfølgende drag i snoren tvinger vrideren til å dreie og låse opp doren. En sådan dorslynge kan, be-nyttes i forbindelse med låser hvis vridere, vinkelrett på disses dreieakse, har hovedsakelig rundt tverrsnitt og forovrig sådan form at snoren ikke sklir av under draget. In the past, so-called "door slings" have been used to unlock such doors and locks, the method of use of which consists in one such device consisting of a cord - from the outside of the door is brought in through the post hatch or the like and wound a suitable number of times around the lock turner such way that a subsequent pull on the string forces the twister to turn and unlock the mandrel. Such a door loop can be used in connection with locks whose twisters, perpendicular to their axis of rotation, have mainly round cross-sections and otherwise such a shape that the string does not slip off under the pull.

Moderne'låser har vridere med hovedsakelig rektangu-læet tverrsnitt og form forovrig som vanskeliggjor eller umuliggjor bruk av dorslynger. Modern locks have twisters with a mainly rectangular cross-section and a shape that makes it difficult or impossible to use door slings.

Oppfinnelsen har derfor til hensikt å tilveiebringe en innretning av den innledningsvis nevnte type, og som er egnet for dorer med dbrvridere av andre former enn runde. The invention therefore aims to provide a device of the type mentioned at the outset, which is suitable for mandrels with screw drivers of other shapes than round.

Det særegne ved oppfinnelsen'fremgår av de i kravene The peculiarity of the invention is apparent from those in the claims

angitte kjennetegnende trekk. specified characteristic features.

.Oppfinnelsen skal nå beskrives nærmere under, hen-visning til tegningene som viser et utforelseseksempel .ifolge oppfinnelsen, og hvor fig. 1 viser et riss av innretningen sett fra .siden, og fig. 2 viser vriderens holdekopp. sett i retningen for pilen A på fig. 1. The invention will now be described in more detail below, with reference to the drawings which show an exemplary embodiment according to the invention, and where fig. 1 shows a view of the device seen from the side, and fig. 2 shows the twister's holding cup. seen in the direction of arrow A in fig. 1.

En låsvrider-holdeinnretning 1 fremstilt av et A lock turner holding device 1 produced by et

egnet materiale, som f.eks. plast eller metall, og tilnærmet utformet som en kopp hvis innvendige form er tilpasset.' formen av låsvrideren 9 for den dor som skal låses opp, suitable material, such as plastic or metal, and roughly designed like a cup whose internal shape is adapted.' the shape of the lock turner 9 for the mandrel to be unlocked,

for at vriderkoppeh 1 skal kunne fores inn på og delvis om-slutte låsvrideren, er fdrbundet med den ene-ende av en bdyelig aksel 2. Akselen 2 er tilnærmet i. hele sin lengde fort i et ror h, f.eks. fremstilt av giddet kobber e.l., således at det gjentagne ganger kan bdyes for hånd. in order for the twister cup 1 to be inserted onto and partially enclose the lock twister, is connected to one end of a flexible shaft 2. The shaft 2 is almost in its entire length fast in a rudder h, e.g. made of tinned copper etc., so that it can be dyed repeatedly by hand.

For montering og eventuell utskiftning av vriderkoppen 1 med en annen vriderkopp som bedre er tilpasset den aktuelle vrider kan. den fortrinnsvis være ldsbart forbundet med den bdyelige aksel 2. Vriderkoppen 1. kan for dette formål ha en sentral ansats 10 med en sentral . boring 11 tilpasset en med den bdyelige aksels 2 ene ende fast forbundet sylindrisk tapp 12 for innfdring i boringen 11. Tappen 12 og ansatsen 10 kan videre være utstyrt med hull diametralt forldpende i forhold til disse deler, og som flukter når tappen er anbragt i boringen 11 for innfdring av en låseskrue 6, låsesplint e.l. Akselend.en kan være fast forbundet med tappen 12 ved at et av denne fra koppen 1 vendende parti 7 er forsynt med en sentral boring tilpasset akselenden, hvilket parti 7?etter innfdring av akselenden, ved krymping, lodding eller på annen måte er fast forbundet med denne. Som vist på fig. 1 kan dette parti 7 også danne opplagring i roret h for akselen 2 ved at tappens 12 utvendige diameter er tilpasset rorets h innvendige diameter og tappens lengde er stor nok, til å sikre tilstrekkelig stor anleggsflate. • For mounting and possibly replacing the twister cup 1 with another twister cup that is better adapted to the current twister. it should preferably be weldably connected to the flexible shaft 2. The turning cup 1. can for this purpose have a central shoulder 10 with a central . bore 11 adapted to a cylindrical pin 12 fixedly connected to one end of the flexible shaft 2 for insertion into the bore 11. The pin 12 and the shoulder 10 can also be equipped with holes diametrically extending in relation to these parts, and which align when the pin is placed in the bore 11 for inserting a locking screw 6, locking pin etc. The shaft end can be firmly connected to the pin 12 in that one of the parts 7 facing away from the cup 1 is provided with a central bore adapted to the shaft end, which part 7 is firmly connected after inserting the shaft end, by shrinking, soldering or in some other way with this one. As shown in fig. 1, this part 7 can also form storage in the rudder h for the axle 2 by the fact that the outer diameter of the pin 12 is adapted to the inner diameter of the rudder h and the length of the pin is large enough to ensure a sufficiently large contact surface. •

Akselens 2 annen ende er fo-rbundét med et håndtak The other end of the shaft 2 is connected to a handle

3 og denne forbindelse kan, i likhet med akselens forbindelse med vriderkoppen 1, være fast eller ldsbar. 3 and this connection, like the shaft's connection with the turning cup 1, can be fixed or removable.

'Roret h er ved den ende som befinner seg ved håndtaket 3 forsynt med et håndtak 5. The rudder h is provided with a handle 5 at the end located at the handle 3.

Innretningens virkemåte- er som folger: En vriderkopp 1.tilpasset den vrider den på doren moterte lås 8 formodes å ha festes til akseltappen 12 ved hjelp av låse-skruen 6. Roret k bdyes deretter til en form tilnærmet lik en halvsirkel, hvis diameter tilnærmet er lik avstanden mellom låsvrideren og postluken, hvoretter roret ledes med. den ende., i hvilken vriderkoppen er festet, inn i postluken, og koppen 1 fores med sin åpning'vendende mot vrideren 9? tilnærmet i'vrideraksens retning, mot vrideren 9. for å oppta denne. Roret h holdes i denne stilling ved hjelp av håndtaket 5 mens håndtaket 3 dreies, hvorved, det i denne akselende tilforte dreiemoment overfores via den boyelige aksel 2 og kopppen 1 til vrideren 9 for opplåsing av doren. The operation of the device is as follows: A twisting cup 1. adapted to it turns the lock 8 mounted on the mandrel, which is supposed to have been attached to the shaft pin 12 by means of the locking screw 6. The rudder k is then bent into a shape approximately equal to a semicircle, whose diameter approximately is equal to the distance between the lock turner and the mail hatch, after which the rudder is guided along. the end., in which the twister cup is attached, into the mail hatch, and the cup 1 is lined with its opening facing the twister 9? approximately in the direction of the twister axis, towards the twister 9. to accommodate this. The rudder h is held in this position by means of the handle 5 while the handle 3 is turned, whereby the added torque at this shaft end is transferred via the bendable shaft 2 and the cup 1 to the twister 9 for unlocking the mandrel.
