Opfindelsen angår en cylinderlås med forbedret opbrydningsmodstand og ifølge krav l's indledning.The invention relates to a cylinder lock with improved breaking resistance and according to the preamble of claim 1.
I cylinderlåse med drejelige låseskiver, som opfindelsen vedrører, 5 forbedres opbrydningsmodstanden eksempelvis ved at anbringe forskellige beskyttelsesplader eller lignende foran låseski vesættet for især at gøre det vanskeligere at få adgang til låsens låsestang ved udboring af låsen. Afhængig af anvendelsen og under hensyntagen til pladsforholdene anvendes især lige låsestænger i den låsetype, som 10 opfindelsen vedrører. I dette tilfælde kan låsestangen, hvis udboring udføres direkte ved låsestangens placering, og hvis den eventuelle beskyttelsesplade svigter, trækkes ud af låsepladen i aksi al retning, og låsen kan åbnes.In cylinder locks with pivotal locking discs to which the invention relates, the breaking resistance is improved, for example, by placing different protective plates or the like in front of the locking disc set, in particular making it more difficult to access the locking locking rod when drilling the lock. Depending on the application and taking into account the space conditions, in particular, straight locking rods are used in the locking type to which the invention relates. In this case, the locking rod, the bore of which is performed directly at the locking rod location and if any protective plate fails, is pulled out of the locking plate in all directions and the locking can be opened.
15 Formålet med opfindelsen er at angive en løsning, der gør det vanskeligere at opbryde låsen, især ved anvendelse af den ovenfor nævnte opbrydningsteknik, idet fjernelse af låsestangen fra låsen forhindres. Et yderligere formål er at angive en løsning, som ud fra et fremstillingsmæssigt og økonomisk synspunkt er fordelagtig.The object of the invention is to provide a solution which makes it more difficult to break the lock, especially by using the breaking technique mentioned above, preventing removal of the locking rod from the lock. A further object is to provide a solution which is advantageous from a manufacturing and economic point of view.

Dette opnås med en indretning, ifølge hvilken den nævnte åbning i låsecylinderen er forsynet med i det mindste én udragende tildannelse, der rager ud på tværs af åbningen og fortrinsvis er anbragt ved den indre ende af denne, og ved at låsestangen tilsvarende er 25 forsynet med en not eller en tilsvarende fordybning beregnet til at samvirke med den nævnte udragende tildannelse for således at forhindre bevægelse af låsestangen i aksial retning ud af åbningen i låsecylinderen. Herved forhindres fjernelse af låsestangen fra låsen, idet låsestangen ved denne låsetype altid forefindes delvist 30 i den nævnte åbning i låsecylinderen. Løsningen har imidlertid ikke indflydelse på den egentlige låsemekanismes virkemåde, hvor 'låsestangens bevægelse i forhold til låsecylinderen sker i låsens radiale retning.This is achieved with a device according to which said opening in the locking cylinder is provided with at least one protruding projection extending transversely of the opening and preferably arranged at the inner end thereof, and by the corresponding locking rod being provided with a groove or a corresponding recess intended to cooperate with said protruding structure so as to prevent movement of the locking rod in axial direction out of the opening in the locking cylinder. This prevents removal of the locking rod from the locking, the locking rod of this locking type always being partially 30 in the said opening in the locking cylinder. However, the solution does not affect the operation of the actual locking mechanism, where the movement of the locking rod relative to the locking cylinder takes place in the radial direction of the locking.
35 i praksis anbringes fordelagtigt en udragende tildannelse på begge sider af åbningen i låsecylinderen, således at de udragende tildannelser fortrinsvis forefindes over for hinanden i forhold til åbningens aksiale retning. I princippet kan der anbringes flere elementer af denne art efter hinanden langs åbningen.In practice, a projecting configuration is advantageously arranged on both sides of the opening in the locking cylinder, so that the projecting formations are preferably facing each other relative to the axial direction of the opening. In principle, several elements of this kind can be arranged one after the other along the opening.

Begrænsningerne herfor udgøres først og fremmest af produktionsteknikken og ekstraomkostningerne som følge heraf.The limitations of this are primarily the production technique and the additional costs as a result.
En fordelagtig løsning set ud fra et produktionsteknisk og funk-5 tionsmæssigt synspunkt opnås, når låsestangen har en i hovedsagen > rund tværsnitsform, hvor den nævnte not eller lignende forefindes rundt om låsestangen. ±An advantageous solution from a production technical and functional point of view is obtained when the locking rod has a generally> round cross-sectional shape, wherein said groove or the like is found around the locking rod. ±
En udførelsesform for opfindelsen beskrives i det følgende nærmere 10 med henvisning til tegningen, hvor fig. 1 viser et tværsnit af en låseanordning ifølge opfindelsen monteret i et funktionsområde, 15 fig. 2 viser delvist et tværsnit af en låsecylinder og en låsestang hørende til låseanordningen vist på fig. 1, og fig. 3 viser delene efter linien III-III på fig. 2.An embodiment of the invention will now be described in greater detail with reference to the accompanying drawings, in which: FIG. 1 is a cross-sectional view of a locking device according to the invention mounted in a functional area; FIG. 2 is a partial cross-sectional view of a locking cylinder and locking rod of the locking device shown in FIG. 1, and FIG. 3 shows the parts along line III-III of FIG. 2nd
20 På fig. 1 er en cylinderlås ifølge opfindelsen som eksempel anbragt i en huslignende konstruktion 1, hvoraf kun en del er vist. Konstruktionen 1 omfatter et nøglehul 2, hvorigennem en nøgle til cylinderlåsen kan indføres i låsen. Låseanordningen omfatter yderligere elementer 3 og 4, der tjener som modstandselementer mod 25 udboring. Den viste cylinderlås omfatter et låselegeme 5, hvori der er anbragt en drejelig låsecylinder 6 omfattende et sæt låseskiver 7, der er drejelige ved hjælp af låsens nøgle. Låsemekanismen omfatter desuden en låsestang 8, der i sin låste stilling er lejret delvist i en not 9 i låselegemet 5's indre overflade og delvist i en 30 åbning 10 i låsecylinderen 6 for derved at forhindre drejning af låsecylinderen 6 i forhold til låselegemet 5.20 In FIG. 1, an exemplary cylinder lock according to the invention is arranged in a housing-like structure 1, of which only a part is shown. The construction 1 comprises a keyhole 2 through which a key for the cylinder lock can be inserted into the lock. The locking device further comprises elements 3 and 4 which serve as resistance elements against drilling. The cylinder lock shown comprises a locking body 5 in which is arranged a rotatable locking cylinder 6 comprising a set of locking discs 7 which are rotatable by the key of the lock. The locking mechanism further comprises a locking rod 8 which, in its locked position, is partially housed in a groove 9 in the inner surface of the locking body 5 and partly in an opening 10 in the locking cylinder 6, thereby preventing rotation of the locking cylinder 6 relative to the locking body 5.
* I overensstemmelse med denne låsetypes kendte funktionsprincip er låseskiverne 7 drejelige ved hjælp af nøglen til en stilling, hvor 35 ved periferien udformede kærve, som ikke er vist på figurerne, danner en lige kanal ud for åbningen 10, således at låsestangen 8 delvis kan indføres i kanalen for derved at tillade låsecylinderen 6 at dreje i forhold til låselegemet 5. Et knastelement 11 monteret på en kraftoverførende del 6a på låsecylinderen 6 drejes samtidig, 3 DK 170508 B1 hvorved området, der er aflåst ved hjælp af cylinderlåsen, kan åbnes. Anordningen vist på fig. 1 omfatter desuden et kugleformet udboringshindrende element 12 anbragt i låsecylinderen 6's indre del.* In accordance with the known principle of operation of this lock type, the lock washers 7 are rotatable by the key to a position in which 35 formed notches in the periphery, not shown in the figures, form a straight channel next to the opening 10, so that the lock rod 8 can be partially inserted in the channel so as to allow the locking cylinder 6 to rotate relative to the locking body 5. A cam element 11 mounted on a power transmitting part 6a of the locking cylinder 6 is rotated simultaneously, thus opening the area which is locked by means of the cylinder lock. The device shown in FIG. 1 further comprises a spherical bore preventing element 12 disposed in the inner portion of the locking cylinder 6.

Som det fremgår mere tydeligt af fig. 2 og 3, er åbningen 10 i låsecylinderen 6 forsynet med udragende tildannelser 13 anbragt ved låsecylinderens indre ende. Låsestangen 8 er forsynet med en not 14 til optagelse af de udragende tildannelser 13. Låsestangen 8, som 10 altid befinder sig delvist i åbningen 10, kan således bevæges i radial retning i forhold til låsecylinderen 6, således som det kræves for at åbne og lukke låsemekanismen, mens bevægelser i åbningen 10's aksiale retning ikke er mulige. I det tilfælde, hvor det på trods af modstandselementerne 3 og 4 mod udboring har været 15 muligt at bore et hul i låsen ved låsestangen 8 med det formål at trække låsestangen 8 ud af låsen, vil det således ikke være muligt at foretage denne udtrækning, idet de nævnte elementer 13 og 14 vil forhindre dette.As can be seen more clearly in FIG. 2 and 3, the opening 10 of the lock cylinder 6 is provided with projecting configurations 13 located at the inner end of the lock cylinder. The locking rod 8 is provided with a groove 14 for receiving the protruding formations 13. The locking rod 8, which is always partially in the opening 10, can thus be moved in a radial direction with respect to the locking cylinder 6, as required for opening and closing. locking mechanism, while movements in the axial direction of aperture 10 are not possible. Thus, in the event that, despite the resistance elements 3 and 4 against bore, it has been possible to drill a hole in the lock at the locking rod 8 for the purpose of pulling the locking rod 8 out of the locking, it will thus not be possible to make this extraction. said elements 13 and 14 will prevent this.
20 Elementerne 13 og 14 kan naturligvis udformes på andre måder. De kan anbringes i andre stillinger, og der kan være flere af dem. Det væsentlige er, at de forhindrer forskydning af låsestangen i dennes aksialretning. Opfindelsen er således ikke begrænset til den viste udførelsesform, men tillader adskillige modifikationer inden for de 25 af kravene givne rammer.The elements 13 and 14 can, of course, be designed in other ways. They can be placed in other positions and there may be several of them. The essential thing is that they prevent displacement of the locking rod in its axial direction. Thus, the invention is not limited to the embodiment shown, but permits several modifications within the scope of the claims.
