Indstikslåse anvendes i døre med forskellige tykkelser. Når en cylinderlås forbindes med en dørlås af indstikstypen, bør cylinderlåsen ved korrekt montering have en bestemt afstand fra dørfladen. Dette medfører, at afstanden mellem cylinderlåsen og dørlåsen må varieres, såle-20 des at afstanden passer til den ved hver montering hørende dørtykkelse. For at tilvejebringe en beskyttelse mod indbrud, må cylinderlåsen desuden have en stærk og vel beskyttet indfatning. Hvis dørtykkelsen varierer inden for brede grænser, bliver det svært at opfylde ovennævnte krav.Insert locks are used in doors of different thicknesses. When a cylinder lock is connected to a door lock of the insert type, the cylinder lock, when properly fitted, should have a certain distance from the door surface. This means that the distance between the cylinder lock and the door lock must be varied so that the distance corresponds to the door thickness associated with each mounting. In addition, in order to provide protection against burglary, the cylinder lock must have a strong and well-protected frame. If the door thickness varies within wide limits, it will be difficult to meet the above requirements.

En låsemekanisme af den indledningsvis nævnte art er kendt fra NO patentskrift nr. 140.020. I denne kendte låseindretning bliver både cylinderlåsens låsehus og kraftoverføringsorganet forlænget stykke for for stykke til den forud ønskede totale længde ved hjælp af adskilte 30 forlængerelementer, der medfører et kompliceret og dyrt arrangement, som består af et større antal dele. Forlængerelementerne giver i øvrigt ingen forlængelse af låsehuset i egentlig forstand, hvilket medfører, at fastgørelsen af cylinderlåsen til dørlåsen ikke er så stærk og så godt beskyttet som ønskeligt.A locking mechanism of the kind mentioned above is known from NO patent specification 140,020. In this known locking device, both the locking housing of the cylinder lock and the power transmission means are extended piece by piece to the desired total length by means of separate 30 extension elements, resulting in a complicated and expensive arrangement consisting of a large number of parts. Incidentally, the extension elements provide no extension of the lock housing in the proper sense, which means that the attachment of the cylinder lock to the door lock is not as strong and as well protected as desired.

Fra US patentskrift nr. 2.381.136 kendes en låsemekanisme, som ligner den indledningsvis nævnte art. Her benyttes to forskellige forlængerskiver til at forlænge låsehuset og specielle skiver lejret i låsehusets forlængerskiver til forlængelse af kraftoverføringsorganet. VedUS Patent No. 2,381,136 discloses a locking mechanism similar to the one mentioned in the introduction. Here, two different extension discs are used to extend the lock housing and special discs stored in the lock housing extension discs for extension of the PTO. By

denne kendte mekanisme opnås også et kompliceret og dyrt arrangement bestående af et større antal dele, og desuden har låsemekanismen den ulempe, at delene ikke kan fastgøres ved hjælp af de midler, som benyttes til at fastgøre cylinderlåsen til dørlåsen, men skal fastgøres 5 til cylinderlåsens låsehus ved hjælp af specielle skruer.this known mechanism also achieves a complicated and expensive arrangement consisting of a plurality of parts, and furthermore, the locking mechanism has the disadvantage that the parts cannot be secured by means used to attach the cylinder lock to the door lock, but must be attached to the cylinder lock. locking housing using special screws.

Fra US patentskrift nr. 1.725.544 kendes endvidere en låsecylinder med et kraftoverføringsorgan i form af et langstrakt pladestykke, der omfatter brudkærve, således at pladestykket kan forkortes ved sin ende 10 modsat låsecylinderen for tilpasning til afstanden mellem låsecylinderen og selve dørlåsen. Ved denne kendte indretning er låsecylinderen imidlertid beregnet til fastgørelse direkte i døren uanset afstanden til dørlåsen, og denne kendte teknik giver derfor ingen anvisninger på, hvorledes selve cylinderlåsen kan forlænges.U.S. Patent No. 1,725,544 also discloses a locking cylinder having a power transmission means in the form of an elongate plate piece comprising a notch, so that the plate piece can be shortened at its end 10 opposite the locking cylinder for adapting to the distance between the locking cylinder and the door lock itself. In this known device, however, the lock cylinder is intended for fastening directly in the door regardless of the distance to the door lock, and this prior art therefore gives no instructions on how the cylinder lock itself can be extended.

Formålet med opfindelsen er at tilvejebringe en låsemekanisme af den indledningsvis nævnte art, som ikke er behæftet med ovennævnte mangler og ulemper. Dette opnås ifølge opfindelsen ved, at dimensionen for hvert forlængerelement i nævnte retning mod dørlåsen udgør en lille 20 del af kraftoverføringsorganets længde, der er regulerbar i nævnte retning til en i hver enkel monteringssituation hensigtsmæssig værdi ved at kraftoverføringsorganet er forsynet med et antal brudkærve, langs hvilke kraftoverføringsorganet forkortes ved den ende, som skal kobles til cylinderlåsen.The object of the invention is to provide a locking mechanism of the kind mentioned in the introduction, which does not suffer from the aforementioned shortcomings and disadvantages. This is achieved according to the invention in that the dimension of each extension element in said direction against the door lock constitutes a small part of the length of the PTO which is adjustable in that direction to a suitable value in each individual installation situation, by the PTO being provided with a plurality of breaking notches, along which power transmission means is shortened at the end to be connected to the cylinder lock.

Brudkærvene kan med fordel omfatte to tværgående spor i kraftoverføringsorganet. Cy-30 linder!åsen og forlængerelementet er forsynet med radialt styrende flader, f.eks. i form af en krave og en tilsvarende indpresning for at tilvejebringe en nøjagtig positionsbestemmelse og en sikker sammenkobling af forlængerelementerne. Forlængerelementerne er også forsynet med indretninger, som forhindrer drejningsbevægelser mellem nærliggen-35 de forlængerelementer eller i forhold til cylinderlåsen. Disse indretninger kan være udført i form af sammenkoblelige fordybninger og fremspring.According to a preferred embodiment of the present invention, the fracture notches are provided at intervals substantially equal to the mounting thickness of each extension member. Advantageously, the fracture joints may comprise two transverse grooves in the PTO. The Cy-30 liner and the extension element are provided with radially guiding surfaces, e.g. in the form of a collar and a corresponding indentation to provide an accurate positioning and secure interconnection of the extension elements. The extension elements are also provided with devices which prevent rotation movements between adjacent extension elements or in relation to the cylinder lock. These devices may be provided in the form of interconnecting recesses and projections.

Afstanden mellem koblingsfladernes tænder bør fortrinsvis svare til afstanden mellem kraftoverføringsorganets brudkærve.5 shows a resilient ring which engages between the teeth of the coupling surfaces. The distance between the teeth of the coupling surfaces should preferably correspond to the distance between the breaking joint of the PTO.

Den ende af kraftoverføringsorganet, som er tilvejebragt nærmest dør-10 låsen, kan hensigtsmæssigt være forsynet med et styreelement, som giver en radial styring i forbindelse med en tilsvarende styreflade i det forlængerelement, som er beliggende nærmest dørlåsen.The end of the PTO provided closest to the door lock may conveniently be provided with a guide member which provides a radial guide in connection with a corresponding guide surface in the extension member located closest to the door lock.

Opfindelsen vil herefter blive forklaret mere detaljeret under henvis-15 ning til den medfølgende tegning, hvor fig. 1 viser et ekspanderet perspektivisk billede af en udførelsesform for opfindelsen, fig. 2 et billede set fra siden af den i fig. 1 viste cylinderlås 20 samt tilhørende kraftoverføringsorgan, og fig, 3 et aksi alt snit gennem et forlængerelement i en mekanisme ifølge den foreliggende opfindelse.The invention will then be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 shows an expanded perspective view of an embodiment of the invention; FIG. 2 is a side view of the one of FIG. 1, and FIG. 3 is an axial section through an extension member of a mechanism according to the present invention.

I tegningen er der vist en dørlås 1, hvortil en cylinderlås 2, der har 25 et ydre stationært låsehus 3 og et drejeligt forbindelsesorgan 5, er fastgjort ved hjælp af skruer 12, der optages i åbninger 21 i dørlåsen 1, og som er indskruet i tilsvarende åbninger 21 i cylinderlåsens låsehus 3. Når cylinderlåsen 2 betjenes med en nøgle, overfører nøglen et drejningsmoment til et kraftoverføringsorgan 4, der er udløseligt 30 tilsluttet til cylinderlåsens forbindelsesorgan 5. Kraftoverføringsorganet 4 er indesluttet i en kanal, der i fællesskab er dannet af åbninger 22, der er tilvejebragt i et antal forlængerelementer 7, som er tilvejebragt mellem cylinderlåsens låsehus 3 og dørlåsen 1. Kraftoverføringsorganet 4 udviser et antal skarpe spor eller indtrykninger 10, 35 som er tilvejebragt med jævne mellemrum, og som danner brudkærve, hvilket medfører, at kraftoverføringsorganet 4 let kan afbrydes ved et hvilket som helst af sporene 10. På denne måde kan der tilvejebringes en regulering af kraftoverføringsorganet 4's længde, således at længden bliver hensigtsmæssig for den aktuelle montering. De dele 6, som 4 »In the drawing, a door lock 1 is shown, to which a cylinder lock 2 having an outer stationary lock housing 3 and a pivotal connecting member 5 is secured by screws 12 which are received in openings 21 in the door lock 1 and which are screwed in corresponding openings 21 in the lock housing of the cylinder lock 3. When the cylinder lock 2 is operated by a key, the key transmits a torque to a power transfer means 4 releasably 30 connected to the connecting means of the cylinder lock 5. The power transfer means 4 is enclosed in a channel jointly formed by openings. 22 provided in a plurality of extension elements 7 provided between the locking housing 3 of the cylinder lock and the door latch 1. The power transmission means 4 exhibits a number of sharp grooves or indentations 10, 35 which are provided at regular intervals and which cause a breakthrough. the power transmission means 4 can be easily interrupted by any of the tracks 10.

befinder sig mellem brudkærvene 10, kan være 3 mm lange, og denne afstand bør fortrinsvis svare til forlængerelementet 7's monteringstyk-kelse D (se fig. 3).located between the fracture jaws 10 may be 3 mm long, and this distance should preferably correspond to the mounting thickness D of the extension element 7 (see Fig. 3).

5 Hvert forlængerelement 7 har en cirkulær krave 13, som passer i en tilsvarende indprægning 14 på et nærliggende forlængerelements modsatte side. For at forhindre drejningsbevægelse mellem nærliggende forlængerelementer eller mellem et forlængerelement og cylinderlåsen, er forlængerelementerne samt cylinderlåsen forsynet med sammenkoblelige 10 fremspring 15 og indprægninger 16. Kraftoverføringsorganet 4 har en koblingsflade 17, der er forsynet med tænder ved begge sine smalle kanter. Når kraftoverføringsorganet 4's ene ende føres ind i en spalte 20 i cylinderlåsens forbindelsesorgan 5, griber en fjedrende ring 18 ind mellem tænderne 17a på koblingsfladerne 17. Afstanden mellem tæn-15 derne 17a svarer også til forlængerelementet 7's monteringstykkelse D.Each extension member 7 has a circular collar 13 which fits into a corresponding embossing 14 on the opposite side of an adjacent extension member. In order to prevent rotational movement between adjacent extension elements or between an extension element and the cylinder lock, the extension elements and the cylinder lock are provided with interchangeable 10 projections 15 and indentations 16. The power transmission means 4 has a coupling surface 17, which has teeth at both its narrow edges. When one end of the PTO 4 is inserted into a slot 20 in the connector 5 of the cylinder lock, a resilient ring 18 engages between the teeth 17a of the coupling surfaces 17. The distance between the teeth 17a also corresponds to the mounting thickness D. of the extension element 7.

Ved den af kraftoverføringsorganet 4's ender, som vender mod dørlåsen, er der tilvejebragt et styreelement 23, som passer ind i det forlængerelement 7, som er beliggende nærmest dørlåsen. Kraftoverføringsor-ganet 4 har også en endedel 11, som passer ind i en tilsvarende spalte 20 (ikke vist) i dørlåsen l's indre mekanisme.At the ends of the PTO 4 facing the door lock, a control element 23 is provided which fits into the extension element 7 which is located closest to the door lock. The power transmission means 4 also has an end portion 11 which fits into a corresponding slot 20 (not shown) in the inner mechanism of the door latch 1.

Dimensionerne for spalten 20 i cylinderlåsens forbindelsesorgan 5 og den fjedrende ring 18's dimensioner svarer til kraftoverføringsorganet 4's dimensioner N og M. Antallet af forlængerelementer 7 og kraftover-25 føringsorganet 4's længde L er bestemt, således at de svarer til den monteringsafstand, som er til stede mellem dørlåsen 1 og cylinderlåsen 2. Kraftoverføringsorganet 4 er fortrinsvis i begge ender forbundet på en sådan måde, at der er tilvejebragt et vist aksialt spillerum, således at praktiske afvigelser fra det teoretiske monteringsmål kan opta-30 ges ved hjælp af dette aksiale spillerum.The dimensions of the slot 20 in the cylinder member connector 5 and the resilient ring 18 dimensions correspond to the N and M. dimensions of the PTO 4 and the number of extension members 7 and the length L of the PTO 4 is determined to correspond to the mounting distance present. between the door lock 1 and the cylinder lock 2. The power transfer means 4 are preferably connected at both ends in such a way that a certain axial clearance is provided, so that practical deviations from the theoretical mounting target can be accommodated by this axial clearance.
