Opfindelsen angår en fremgangsmåde til forankring af et slutblik eller et hængsel, således som nærmere angivet i krav l's indledning.The invention relates to a method for anchoring a final look or a hinge, as further specified in the preamble of claim 1.

5 Der kendes allerede forslag til en sådan særlig udformning af dørlåse med tilhørende slutblik, at der opnås en vis forøgelse af den kraft, der er nødvendig til at forcere låsen, f.eks. ved indbrud, i forhold til sædvanlige låse, jf. f.eks. DK-FS nr. 145.163 og US-PS nr. 3.888.530 og nr.5 There are already known proposals for such a special design of door locks with the corresponding endplate that a certain increase in the force needed to force the lock, e.g. in case of burglary, in relation to usual locks, cf. DK-FS no. 145,163 and US-PS no. 3,888,530 and no.

Der kendes imidlertid ingen vejledning til at forstærke fastgørelsen af et slutblik af sædvanlig art, der tilhører en normalt udformet dørlås eller et hængsel, som allerede 15 er monteret på dørkarmen, i f.eks. sådanne situationer, hvor man, først efter at låsen henholdsvis hængslet er blevet monteret, er blevet opmærksom på, at evnen til at modstå indbrudsforsøg ikke er tilstrækkelig.However, there is no known guide to reinforcing the attachment of a usual type of endplate belonging to a normally formed door lock or a hinge already mounted on the door frame, e.g. such situations where, only after the lock or the hinge has been mounted, it becomes aware that the ability to withstand burglary attempts is insufficient.

20 En sådan vejledning er at finde i krav l's kendetegnende del. Ved at gå frem på den således angivne måde opnås, at en eller flere af de træskruer eller lignende, hvormed slut-blikket eller hængslet tidligere har været fastgjort til dørkarmens træ - og hvis evne til at modstå forsøg på at 25 forcere døren er begrænset - erstattes af en skrue, der strækker sig gennem et tværgående hul i bolten, der er sikret mod udtrækning i en retning svarende til en forcering af døren. Herved sikres låsen på i princippet stort set samme måde som omtalt i ovennævnte publikationer, men 30 - uden at foretage radikale indgreb i selve låsen eller slutblikket, uden brug af specialværktøj, og uden at udføre skæmmende arbejdsoperationer på dørkarmen eller tilstødende dele.20 Such a guide is to be found in the characteristic part of claim 1. By proceeding in the manner thus stated, one or more of the wooden screws or the like, with which the end-eye or hinge has been previously attached to the door frame tree - and whose ability to resist attempts to force the door is limited - is replaced by a screw extending through a transverse hole in the bolt secured against extraction in a direction similar to the forcing of the door. In this way, the lock is secured in basically the same way as mentioned in the above publications, but 30 - without making radical interventions in the lock itself or the final look, without the use of special tools, and without performing disgusting work operations on the door frame or adjoining parts.

Ved at gå frem på den i krav 2 angivne måde opnås yderligere, 35By proceeding in the manner specified in claim 2, further is achieved

2 at bolten eller boltene skjules, hvad der kan være hensigtsmæssigt for at forhindre, at en indbrudstyv forsøger at fjerne det organ, der sikrer bolten mod udtrækning, og desuden er fordelagtigt af æstetiske grunde.2 that the bolt or bolts are concealed, which may be appropriate to prevent a burglar from attempting to remove the body securing the bolt against retraction, and is additionally advantageous for aesthetic reasons.

Opfindelsen angår også et emnesæt til udøvelse af fremgangsmåden ifølge opfindelsen, og dette emnesæt er ifølge opfindelsen ejendommeligt ved det i krav 3's kendetegnende del angivne. Et sådant emnesæt kan tilpasses efter den dørkarm, 10 hvortil det pågældende slutblik henholdsvis hængsel er fastgjort, idet det første emne kan afkortes til den ønskede længde, dersom dette er nødvendigt.The invention also relates to a workpiece set for carrying out the method according to the invention, and this workpiece set according to the invention is peculiar to the characterizing part of claim 3. Such a workpiece set can be adapted to the door frame 10 to which the final look and hinge respectively are attached, the first workpiece being shortened to the desired length, if necessary.

Ved den i krav 4 angivne særlige udformning af det første 15 emne opnås, at dette emne kan fremstilles ud fra lagervare i form af gevindskåret emnestangstål.By the particular design of the first item according to claim 4, it is achieved that this item can be manufactured from stock goods in the form of threaded workpiece steel.

Opfindelsen skal i det følgende forklares under henvisning til tegningen, der viser et udførelseseksempel på et sikker-20 hedsanker ifølge opfindelsen, idet fig. 1 er et vandret snit gennem de dele af en dør og tilhørende dørkarm med det færdigmonterede sikkerhedsanker, der ligger nærmest låsen, og 25 fig. 2 viser i perspektiv forbindelsen mellem sikkerhedsankeret og et på dørkarmen monteret slutblik.The invention will be explained in the following with reference to the drawing which shows an embodiment of a safety anchor according to the invention, fig. 1 is a horizontal section through the portions of a door and associated door frame with the pre-assembled security anchor closest to the lock; and FIG. 2 shows in perspective the connection between the security anchor and a final look mounted on the door frame.

Sikkerhedsankeret består af et stykke 12 mm tykt rundstål 30 2, hvorpå der i den ene ende er et gevind med en påskruet møtrik 3, og ved den anden ende er der med en afstand på 13 mm fra enden til centrum udformet et gevindboret hul, hvori der er indskruet en 5 mm tyk maskinskrue 1 til fastholdelse af det viste slutblik 4, som er påmonteret karmen 6 og sam-35 virker med låsen 5, der er påmonteret døren 7.The safety anchor consists of a piece of 12 mm thick round steel 30 2, on which at one end is a thread with a screwed nut 3, and at the other end a threaded hole 13 mm is formed from the end to the center, in which a 5 mm thick machine screw 1 is screwed in to hold the shown end plate 4 mounted on the frame 6 and cooperates with the lock 5 mounted on the door 7.

Ved forsøg på sprængning af døren 7, dvs. ved påvirkning opad i fig. 1, vil sikkerhedsankeret 2 fastholde slutblikket 4 til dørkarmen 6, idet møtrikken 3 danner et ankerhoved.When attempting to burst the door 7, ie. by upward influence in FIG. 1, the safety anchor 2 will hold the final look 4 to the door frame 6, the nut 3 forming an anchor head.

5 På tegningen er kun anvendt ét sikkerhedsanker, men det er muligt at anvende flere på samme dørbeslag.5 Only one safety anchor is used in the drawing, but it is possible to use several on the same door bracket.

Ved montering af et enkelt sikkerhedsanker 2 går man frem på følgende måde: 10 I en af de træskruer, der fastholder slutblikket 4 til karmen 6, fj ernes, II fra karmen 6's modsatte side bores et hul, der strækker sig gennem karmen i højde med det hul, hvorfra den nævnte træskrue er blevet fjernet, og et stykke 15 forbi dette hul, III i det i karmen 6 borede hul indsættes eller indskrues bolten 2, hvori der på forhånd er boret og fortrinsvis gevindskåret et tværgående hul i en sådan position, at det ved indsætning eller indskruning af bolten 2 20 i sit hul kommer til at flugte med det hul, hvorfra træskruen er blevet fjernet, idet sidstnævnte hul om nødvendigt opbores til en større diameter, IV i stedet for den fjernede træskrue indskrues gennem slutblikket 4 og det pågældende tværgående hul i 25 bolten 2 en skrue 1, og V hver bolt 2 sikres mod udtrækning, f.eks. ved at den bliver forsynet med et hoved i form af en påskruet møtrik 3. 1When installing a single safety anchor 2, proceed as follows: 10 In one of the wooden screws holding the final look 4 to the frame 6, the spring, II from the opposite side of the frame 6, drill a hole extending through the frame with height the hole from which said wood screw has been removed and a piece 15 past this hole, III is inserted or screwed into the hole drilled in the frame 6, in which the bolt 2 is pre-drilled and preferably threaded a transverse hole in such a position; by inserting or screwing in the bolt 2 20 in its hole, it will align with the hole from which the wood screw has been removed, drilling the latter hole if necessary to a larger diameter, IV instead of the removed wood screw being screwed through the final sheet 4 and the respective transverse hole in the bolt 2 is a screw 1 and V each bolt 2 is secured against extraction, e.g. by being provided with a head in the form of a screwed-in nut 3. 1

Ved montering af et sikkerhedsanker på hver af de ikke viste dørhængsler går man frem på tilsvarende måde ved at forankre de til karmen hørende hængselblade til denne.When mounting a safety anchor on each of the door hinges not shown, one proceeds similarly by anchoring the hinges belonging to the frame to it.
