Description
Tilholderskive for sylinderlås. Retainer disc for cylinder lock.
Oppfinnelsen vedrører tilholderskriver for sylinderlåser. The invention relates to a holder printer for cylinder locks.
Låsen av det her omhandlete slag omfatter The lock of the type referred to here includes
i låsesylinderen en stabel ko-aksialt anordnete runde tilholderskriver, mellom hvilke er anbragt aksialt fjærende elementer, således at skivene holdes stadig fjærbelastet i ønsket stilling i for-hold til hverandre. Tilholderskivene i disse låser er forsynt med en uttagning i omkretsen bereg-net på å oppta en låsepinne. Når ved låsens man-øvrering nøkkelen, anbragt i en for formålet i midten av skivene anordnet uttagning, har drei-et tilholderskivene en bestemt vinkel bringes deres omkretsuttagninger på linje med hverandre. Låsepinnen, som i hvilestilling ligger i et in the locking cylinder, a stack of coaxially arranged round retainers, between which are placed axially springy elements, so that the discs are kept constantly spring-loaded in the desired position in relation to each other. The retainer discs in these locks are provided with a recess in the circumference designed to accommodate a locking pin. When at the lock's man-upper ring the key, placed in a cut-out arranged for the purpose in the middle of the discs, turns the retaining discs at a certain angle, their circumferential cut-outs are brought in line with each other. The locking pin, which in rest position is in a
i låsesylinderveggen utformet spor og innad hviler mot tilholderskivenes omkretskant, kan da synke ned i de på linje med hverandre beliggende uttagninger i tilholderskivene, slik at grooves formed in the lock cylinder wall and resting on the inside against the circumferential edge of the retainer discs, can then sink into the aligned recesses in the retainer discs, so that
låsesylinderen fritt kan dreies, låsestemplet fri-gjøres og låsen åpnes. the lock cylinder can be turned freely, the lock piston is released and the lock is opened.
En ulempe ved en slik konstruksjon har vært at man med et tynt og hensiktsmessig bøyet inn-bruddsverktøy innført gjennom nøkkelåpningen har kunnet kjenne hvorledes omkretsuttagning-ene for låsepinnen har vært beliggende og ordne uttagningene på linje. A disadvantage of such a construction has been that with a thin and appropriately bent burglary tool inserted through the key opening, it has been possible to know how the circumferential recesses for the locking pin have been located and arrange the recesses in line.
For å vanskeliggjøre slik lokalisering av om-kretsuttagningene i .tilholderskivene har man utført disse med et eller flere andre i omkretsen beliggende uttagninger, såkalte narrespor, hvilke imidlertid har vært av så liten dybde at låsepinnen ikke har kunnet trenge inn i disse tilstrekkelig til at sylinderen fritt har kunnet dreies. In order to make it difficult to locate the circumferential recesses in the retaining discs, these have been made with one or more other recesses located in the circumference, so-called slotted grooves, which, however, have been of such a small depth that the locking pin has not been able to penetrate them sufficiently for the cylinder could be turned freely.
Det har imidlertid vist seg at disse villedende narrespor i omkretsen ikke har vært tilstrekkelig til å hindre oppdirkning av låsen. For å oppnå en helt effektiv sikring mot oppdirking foreslås det ifølge oppfinnelsen en tilholderskive for sylinderlås, hvilken skive er forsynt med et uttak for låsens sperreorgan og et antall narrespor i form av på skivens ene eller begge sider anordnede aksiale fordypninger av vesentlig samme form som uttaket for låsens sperreorgan, idet det nye og karakteristiske er at tilholderskiven ved i det minste en av de aksiale fordypninger er forsynt med en grunn, radial fordypning, fortrinnsvis med vesentlig samme periferiene utstrekning som den aksiale fordypning. However, it has been shown that these deceptive tricks in the perimeter have not been sufficient to prevent the lock being picked. In order to achieve a completely effective protection against prying, the invention proposes a retainer disc for a cylinder lock, which disc is provided with an outlet for the lock's locking device and a number of slotted grooves in the form of axial recesses arranged on one or both sides of the disc of essentially the same shape as the outlet for the locking device of the lock, the new and characteristic feature being that the retainer disc at least one of the axial recesses is provided with a shallow, radial recess, preferably with substantially the same peripheral extent as the axial recess.
Det er,fra tidligere kjent to forskjellige typer av narrespor, nemlig radiale og aksiale med mindre utstrekning i radial resp. aksial retning enn There are, as previously known, two different types of tracks, namely radial and axial with a smaller extent in the radial resp. axial direction than
den for låsepinnen beregnete uttagning i tilholderskiven. Oppfinnelsen innebærer imidlertid betydelig mere enn dette. Det er ikke tilstrekkelig at de to typer av narrespor foreligger på samme skive, de må dessuten være kombinert i samme spor, slik at derved en ny type av narrespor fåes, som i høy grad er egnet til å forville den, som søker å føle seg frem til den rette lås-kombinasjon. Forskjellene mellom de kjente typer av narrespor og oppfinnelsen kan synes å være små, men ikke desto mindre oppnåes ved oppfinnelsen en forvillende virkning som er meget mere effektiv enn hva som kan oppnåes med de kjente typer av narrespor. Ved oppfinnelsen er det i praksis blitt helt umulig å dirke opp låsen. the cut-out intended for the locking pin in the retainer disc. However, the invention involves considerably more than this. It is not sufficient that the two types of fool's tracks are present on the same disk, they must also be combined in the same track, so that thereby a new type of fool's track is obtained, which is highly suitable to mislead the one who seeks to feel until the right lock combination. The differences between the known types of spoofs and the invention may appear to be small, but nevertheless the invention achieves a misleading effect that is much more effective than what can be achieved with the known types of spoofs. With the invention, it has become practically impossible to pry open the lock.
Anordningen ifølge oppfinnelsen kan i det hele tatt ikke oppdages med noen av de kjente metoder. Hvorledes man enn forsøker å føle seg frem, vil narrésporet i alle henseende føles som det riktige spor for låsepinnen. Med bare to narrespor på hver tilholderskive fåes ved ni skiver 19683 muligheter for å kombinere narre-sporene og de ekte spor. Bare en av disse kom-binasjonsmuligheter er den riktige. I praksis kan man således nøye seg med å anordne narrespor ifølge oppfinnelsen bare på noen av tilholderskivene. The device according to the invention cannot be detected at all with any of the known methods. No matter how you try to feel yourself out, the trick track will in all respects feel like the right track for the locking pin. With only two trick tracks on each holder disc, nine discs give 19,683 possibilities for combining the trick tracks and the real tracks. Only one of these combination possibilities is the correct one. In practice, one can thus be satisfied with arranging fool's tracks according to the invention only on some of the retaining discs.
Av de tilholderskiver som forekommer i en låsesylinder kan en eller flere eventuelt samtlige være forsynt med slike villedende uttagninger, hvorved en oppdirkning gjøres praktisk talt umulig eller vanskeliggjøres i høy grad. Of the retainer discs that occur in a locking cylinder, one or more may possibly all be provided with such misleading recesses, whereby a lifting is made practically impossible or made very difficult.
På tegningen vises en utførelse av oppfinnelsen. The drawing shows an embodiment of the invention.

Figs 2 and 3 show the edge of the retaining disc seen from the line II—II and III—III respectively. - Fig. 4 shows, seen from the side, another embodiment of a retainer disc according to the invention. Figs 5 and 6 show the edge of this retaining disc seen from the line V—V and VI—VI respectively.
Tilsvarende deler på de forskjellige figurer Corresponding parts on the different figures
er betegnet med samme henvisningstall. are denoted by the same reference number.
Ifølge fig. 1, 2 og 3 er tilholderskiven forsynt med fordypninger ifølge oppfinnelsen bare på skivens ene side. Tilholderskiven er betegnet med 1, uttagningen for låsepinnen 2, sidefor-dypningen ifølge oppfinnelsen 4. Et i og for seg kjent narrespor med liten dybde er betegnet med 3. Den ene sidefordypning ifølge oppfinnelsen er som det sees kombinert med narrésporet. According to fig. 1, 2 and 3, the retaining disk is provided with recesses according to the invention only on one side of the disk. The retainer disc is denoted by 1, the recess for the locking pin 2, the side recess according to the invention 4. A well-known trick groove with a small depth is denoted by 3. The one side recess according to the invention is, as can be seen, combined with the trick groove.
Utførelsen fiølge fig. 4—6 skiller seg fra den ovenfor beskrevne, ved at fordypningene er utformet på begge sider av låseskiven. The design according to fig. 4-6 differ from the one described above, in that the recesses are designed on both sides of the locking disc.
Som det fremgår av tegningen stemmer for-dypningenes 4 profil, sett mot låseskivens plan, praktisk talt overens med uttagets 2 profil. As can be seen from the drawing, the profile of the recesses 4, viewed against the plane of the locking disc, practically matches the profile of the socket 2.
Det har ved praktisk utførte forsøk vist seg å være nesten umulig med en dirk å føle seg frem til det riktige skiveuttags 2 stilling, sær-deles hvis en eller flere fordypninger ifølge oppfinnelsen er kombinert med narrespor av van-lig utførelse, hvorfor en lås med tilholderskiver ifølge oppfinnelsen med god grunn kan betegnes som dirkefri. In practical tests it has been shown to be almost impossible with a pry bar to feel the position of the correct disc socket 2, especially if one or more recesses according to the invention are combined with a slot of a conventional design, why a lock with retainer discs according to the invention can with good reason be described as burr-free.
