Description

Izum se odnosi na cilindar bravu i odnosno ili plosnati ključ za cilindar bravu s okretnom jezgrom cilindra koja se nalazi u provrtu kućišta cilindra s kanalom za ključ, kao i sa središnjim umetkom i umetkom u kućištu, koji se mogu pomicati kao držači jezgre odnosno zubaca na nazubljenom dijelu plosnatog ključa iz zapornog položaja u kojem je blokirano okretanje jezgre cilindra u položaj otpiranja, pri čemu dio najmanje jednog središnjeg umetka koji strši u kanal za ključ, naročito dio središnjeg umetka koji se nalazi najbliže otvoru za ključ, na svojoj površini plašta ima zahvatni spoj s krilom na nazubljenom dijelu ključa koji strši u smjeru uvlačenja ključa. The invention relates to a lock cylinder and or a flat key for a lock cylinder with a rotating cylinder core located in a bore of the cylinder housing with a channel for the key, as well as with a central insert and an insert in the housing, which can be moved as holders of the core or the teeth on the serrated part of the flat key from the locking position in which the rotation of the cylinder core to the release position is blocked, whereby the part of at least one central insert that protrudes into the key channel, in particular the part of the central insert that is located closest to the key opening, has a gripping surface on its mantle surface a joint with a wing on the toothed part of the key that protrudes in the direction of the key's insertion.

Iz AT 396 957 B poznat je ključ koji u području svojih zubaca, najbliže vrhu zubaca ključa, ima zarez u koji u smjeru uvlačenja strši prednapregnuto krilo, naročito kukica. Zarez nazubljenja ključa, najčešće naćvastog oblika djelomično je pokriven kukicom. Zbog takove konstrukcije taj ključ je vrlo teško izraditi. Uobičajene glodalice za kopiranje ključeva reproduciraju neispravan ključ. Zupcem se vrlo dobro prenosi zakretni moment između ključa i cilindar brave, jer učinkovita visina sjekirice ključa u kanalu za ključ u svakom slučaju ima maksimalnu moguću visinu. Ključ djeluje nadalje zajedno s naročitom cilindar bravom tako da čvrsto drži kuku pripadnog središnjeg umetka i tako sprečava uranjanje središnjeg umetka u šupljinu u kućištu i blokira okretanje jezgre cilindra. From AT 396 957 B, a key is known which has a notch in the area of its teeth, closest to the tip of the key teeth, into which a pre-stressed wing, especially a hook, protrudes in the direction of insertion. The notch of the serrations of the key, usually of a pin-shaped shape, is partially covered by a hook. Due to such a construction, this key is very difficult to make. Common key duplicating mills reproduce a defective key. The tooth transmits the torque between the key and the lock cylinder very well, because the effective height of the key ax in the key channel has the maximum possible height in any case. The key further works together with the special cylinder lock so that it firmly holds the hook of the corresponding central insert and thus prevents the immersion of the central insert into the cavity in the housing and blocks the rotation of the cylinder core.

Namjera izuma je s ključem opisane vrste postići dodatnu funkciju naročite cilindar brave, naime središnji umetak, koji u zapornom položaju uranja u provrt kućišta, dovesti u položaj otpiranja i u njemu ga čvrsto držati. The purpose of the invention is to achieve an additional function of a special cylinder lock with a key of the described type, namely the central insert, which in the locking position plunges into the housing bore, bring it to the release position and hold it firmly in it.

To se postiže time da je opružni umetak u kućištu, pridružen središnjem umetku, izgrađen s graničnikom za ograničenje njegovog hoda, pri čemu se čeona površina umetka u kućištu nalazi u položaju graničnika u unutrašnjosti provrta kućišta blizu središnjeg provrta i čeona površina umetka u kućištu tvori dno šupljine u koju središnji umetak uranja u zapornom položaju, i da zahvatni spoj između ključa i središnjeg umetka ima najmanje jednu kosu površinu za podizanje središnjeg umetka iz zapornog položaja u položaj otpiranja. Kod stavljanja ispravnog ključa ta kosa površina podiže središnji umetak iz šupljine u kućištu cilindra i s njegovom čeonom plohom donosi ga do plohe razdiobe između jezgre cilindra i kućišta cilindra. This is achieved by the fact that the spring insert in the housing, attached to the central insert, is built with a stop to limit its travel, whereby the front surface of the insert in the housing is located in the position of the stop inside the housing bore close to the central bore and the front surface of the insert in the housing forms the bottom of the cavity into which the central insert plunges in the locking position, and that the engagement joint between the key and the central insert has at least one inclined surface for lifting the central insert from the locking position to the release position. When inserting the correct key, this inclined surface lifts the central insert out of the cavity in the cylinder housing and brings it with its face to the dividing surface between the cylinder core and the cylinder housing.

Time se cilindar brava može blokirati. Kosa površina može se predvidjeti na ključu u području istaknutog krila jednog zareza zupca, nazubljene strane ključa, najbližeg vrhu ključa. Obratno, ona se tehnički također može predvidjeti i na središnjem umetku ili također na njemu, kao također i na istaknutom krilu This can block the lock cylinder. A beveled surface can be provided on the key in the area of the prominent wing of one notch of the tooth, the toothed side of the key, closest to the tip of the key. Conversely, it can technically also be foreseen on the central insert or also on it, as well as on the prominent wing

nazubljenog dijela ključa. Svrhovito je ako se u području glave središnjeg umetka, postrance u površini plašta, predvidi utor oblika slova V, a istaknuto krilo, koje strši u smjeru uvlačenja preko zareza ključa, postavljeno na nazubljeni dio ključa i pridruženo središnjem umetku, izrađeno je kao dio kukastog zupca koji podiže kosu površinu središnjeg umetka. Utor se također može izraditi u obliku prstenastog utora oblika slova V. of the serrated part of the key. It is expedient if a V-shaped groove is provided in the area of the head of the central insert, laterally in the surface of the mantle, and the prominent wing, which protrudes in the direction of insertion over the notch of the key, placed on the serrated part of the key and attached to the central insert, is made as part of a hooked tooth which raises the slanted surface of the central insert. The groove can also be made in the form of an annular V-shaped groove.

Dolaskom na kosu površinu središnji umetak zahvaća se i podiže zajedničkim djelovanjem s kukastim zupcem. Nagib kose površine i njena duljina odmjerena je tako da hod središnjeg umetka odgovara dubini šupljine u kućištu cilindra. Arriving on the inclined surface, the central insert is engaged and lifted by joint action with the hook tooth. The inclination of the inclined surface and its length are measured so that the stroke of the central insert corresponds to the depth of the cavity in the cylinder housing.

Naročiti oblik izvedbe karakteriziran je time, da je opipni umetak postavljen tako da se može pomicati u provrtu jezgre cilindra, koji ulazi u provrt središnjeg umetka, i da opipni umetak može izvući središnji umetak, koji je uvučen iz položaja razdiobe u unutrašnjost jezgre cilindra, iz jezgre cilindra u zaporni položaj, u kojem opipni umetak uranja u šupljinu u kućištu. Time je osigurano da otpiranje uspijeva samo pomoću ovdje spomenutog središnjeg umetka stvarno samo u jednom jedinom položaju pomaka. Ako razdioba nije dosegnuta, tada cilindar blokira, jer središnji umetak još uranja u šupljinu. Kad se središnji umetak podigne iznad razdiobe, tada on istiskuje opipni umetak bočno u šupljinu kućišta i cilindar je opet blokiran. Da bi se postiglo sigurno zapiranje, svrhovito je središnji umetak prednapregnuti u smjeru izvlačenja iz jezgre cilindra pomoću opruge. A particular form of performance is characterized by the fact that the tactile insert is positioned so that it can be moved into the bore of the cylinder core, which enters the bore of the central insert, and that the tactile insert can pull out the central insert, which is drawn from the distribution position into the interior of the cylinder core, from the cylinder core into the locking position, in which the tactile insert sinks into the cavity in the housing. This ensures that the opening only succeeds by means of the central insert mentioned here in really only one displacement position. If the distribution is not reached, then the cylinder blocks, because the central insert still sinks into the cavity. When the central insert rises above the distribution, then it pushes the feeler insert laterally into the housing cavity and the cylinder is again blocked. In order to achieve a secure closure, it is expedient to preload the central insert in the direction of withdrawal from the cylinder core by means of a spring.

Na crtežima je prikazan izvedbeni primjer predmeta prema izumu. Slika 1 prikazuje uzdužni presjek kroz dio cilindar brave u zabravljenom položaju, slika 2 prikazuje cilindar bravu sa slike 1 s odgovarajućim ključem u nezabravljenom položaju i slika 3 prikazuje presjek koji odgovara slici 2. The drawings show an exemplary embodiment of the object according to the invention. Figure 1 shows a longitudinal section through part of the lock cylinder in the locked position, Figure 2 shows the lock cylinder of Figure 1 with the corresponding key in the unlocked position and Figure 3 shows a cross section corresponding to Figure 2.

Cilindar brava obuvaća kućište cilindra 1 sa središnjim provrtom u kojem je jezgra cilindra 2 smještena tako da se može okretati. U uobičajenim konstrukcijama središnjeg dijela cilindar brave, pet, šest ili sedam nizova središnjih i umetaka u kućištu raspoređeno je u radijalnim provrtima tako da se mogu pomicati, a istisnu se iz zabravljenog položaja odgovarajućim ključem tako da dotične dodirne površine središnjih umetaka leže s umecima u kućištu na površini središnjeg provrta. Pomicanje središnjeg umetka i umetka u kućištu vrši se pomoću nazubljenja raspoređenog na nazubljenom dijelu ključa, odnosno pomoću zareza. The lock cylinder covers the cylinder housing 1 with a central hole in which the cylinder core 2 is located so that it can be rotated. In the usual constructions of the central part of the lock cylinder, five, six or seven rows of central and inserts in the case are arranged in radial bores so that they can be moved, and are forced out of the locked position by a suitable key so that the respective contact surfaces of the central inserts lie with the inserts in the case on the surface of the central bore. The movement of the central insert and the insert in the housing is done by means of serrations arranged on the serrated part of the key, that is, by means of notches.

Na slikama je prikazan prvi držač umetka. Prema izumu on odstupa od gore opisanog klasičnog načela djelovanja. Umetak 3 u kućištu izrađen je stanjen i djeluje zajedno s graničnikom 4. The pictures show the first insert holder. According to the invention, it deviates from the classical principle of operation described above. The insert 3 in the housing is made thin and works together with the stop 4.

Time je ograničen hod unutar provrta 5 u kućištu. Čeona površina umetka 3 u kućištu nalazi se u položaju graničnika koji maksimalno ograničava hod (npr. slika 1), pomaknuta malo natrag u odnosu na središnji provrt, i tvori dno šupljine 6 u koju, prema slici 1, uranja središnji umetak 7. Time je blokirano okretanje jezgre cilindra 2 u kućištu cilindra. Cilindar brava je zabravljena. This limits the movement inside the bore 5 in the housing. The front surface of the insert 3 in the housing is in the position of the limiter, which maximally limits the stroke (e.g. figure 1), moved a little back in relation to the central bore, and forms the bottom of the cavity 6 into which, according to figure 1, the central insert 7 is immersed. blocked rotation of the cylinder core 2 in the cylinder housing. The lock cylinder is locked.

Središnji umetak 7 nosi bočno utor 10 V-oblika s kosom površinom 11 - okrenut prema otvoru kanala za ključ 8 - kao zaključni element oblika u svrhu zahvatnog spoja s ključem 9 (slika 2) . Kako je prikazano na slici 3, opruga 12 djeluje na središnji umetak 7. Kad u kanal 2 za ključ nije utaknut nikakav ključ 9 (slika 1), tada opruga 12 istiskuje središnji umetak 7 iz jezgre cilindra 2, sve dok središnji umetak 7 zahvati zabravljujući u šupljinu 6. The central insert 7 bears laterally a V-shaped slot 10 with a slanted surface 11 - facing the opening of the channel for the key 8 - as a closing element of the shape for the purpose of engaging connection with the key 9 (Fig. 2). As shown in Figure 3, the spring 12 acts on the central insert 7. When no key 9 is inserted into the key channel 2 (Figure 1), then the spring 12 pushes the central insert 7 out of the cylinder core 2, until the central insert 7 engages locking into cavity 6.

Običan ključ sa zarezima i zupcima na nazubljenom dijelu ključa kod uvlačenja u kanal za ključ 8 utiskuje središnji umetak 7 i umetak u kućištu 3 u svakom slučaju još dublje u provrt 5. Cilindar brava ne može se zabraviti niti u jednom od tih položaja. An ordinary key with notches and teeth on the serrated part of the key, when inserted into the key channel 8, presses the central insert 7 and the insert in the housing 3 even deeper into the bore 5 in any case. The lock cylinder cannot be locked in any of these positions.

Pravilan ključ 9 na kukastom zupcu 15 u području zareza ključa 13 ima krilo 14, koje u smjeru uvlačenja strši preko zareza ključa 13 i djelomično ga prekriva. Krilo 14 izrađeno je kao kosa površina koja se podudara s kosom površinom 11 središnjeg umetka 7. Kod uvlačenja ključa 9 u kanal za ključ 8 kose površine 11 do 14 kližu jedna po drugoj i središnji umetak 7 se podiže nasuprot sili opruge 12. Kad je pravilan ključ 9 potpuno uguran (slika 2), tada hod odgovara dubini šupljine 6. Tako se središnji umetak 7 nalazi potpuno unutar jezgre cilindra 2, koja se sada može okrenuti u kućištu 1 (pod uvjetom, naravno, da su ovdje neprikazani držači dovedeni na podjelu). A regular key 9 on the hook tooth 15 in the area of the key notch 13 has a wing 14, which in the direction of insertion protrudes over the key notch 13 and partially covers it. The wing 14 is made as an inclined surface that coincides with the inclined surface 11 of the central insert 7. When the key 9 is inserted into the key channel 8, the inclined surfaces 11 to 14 slide on each other and the central insert 7 rises against the force of the spring 12. When it is correct the key 9 fully pushed in (Fig. 2), then the stroke corresponds to the depth of the cavity 6. Thus, the central insert 7 is completely inside the core of the cylinder 2, which can now be turned in the housing 1 (provided, of course, that the holders not shown here are brought to the division ).

Središnji umetak 7 drži se čvrsto u svom položaju otpiranja i spriječeno je da ga se oprugom 12 pritisne u šupljinu 6 ili u dodatnu šupljinu u zakretnom području središnjeg umetka 7. Običan ravan ključ neće središnji umetak 7 pritisnuti prema dolje, čime se također povlači opružni umetak 3 u kućištu, pri čemu se ne dosegne svaki puta razdiobu. Budući da je središnji umetak 7 izrađen stanjen, kad jezgra cilindra 7 dosegne razdiobu neprikazanih držača, ona se doduše neznatno otkrene iz osnovnog položaja. Međutim daljnje okretanje jezgre 2 cilindra blokira se s graničnikom stanjenog područja središnjeg umetka 7 na stijenku provrta kućišta 5. The central insert 7 is held firmly in its release position and is prevented by the spring 12 from being pressed into the cavity 6 or into an additional cavity in the pivoting area of the central insert 7. An ordinary flat key will not press the central insert 7 down, which also pulls the spring insert 3 in the housing, where the distribution is not reached every time. Since the central insert 7 is made thin, when the core of the cylinder 7 reaches the distribution of the holders not shown, it is admittedly slightly opened from the basic position. However, further rotation of the cylinder core 2 is blocked by the limiter of the thickened area of the central insert 7 on the wall of the housing bore 5.

Zbog svog opružnog djelovanja i ekscentričnog zahvatnog umetka 16, središnji umetak 7 izrađen je tako da se ne može okretati. Na slici 3 prikazan je opipni umetak 17, koji se nalazi u provrtu poprečnom prema kanalu za ključ 8 i istiskuje se prema van od središnjeg umetka 7 kad je središnji umetak podignut preko površine razdiobe. Tada opipni umetak 17 zahvaća zabravljujući u šupljinu kućišta 18. Provrt za opipni umetak 17 može biti izrađen koso prema zakretnoj osi jezgre cilindra 2, što kod zaključavanja sprečava klizanje opipnog umetka 17 u šupljinu 6. To se može spriječiti i tako da opipni umetak 17 djeluje opružno u smjeru kanala ključa 8. Opipni umetak 17 može biti izrađen cilindrično, ili u području svog zahvata također i kao kliznik oblika kvadra. Due to its spring action and the eccentric engaging insert 16, the central insert 7 is made so that it cannot rotate. Figure 3 shows the tactile insert 17, which is located in a bore transverse to the key channel 8 and is pushed outwards from the central insert 7 when the central insert is raised over the partition surface. Then the tactile insert 17 engages by locking in the cavity of the housing 18. The bore for the tactile insert 17 can be made obliquely to the pivot axis of the cylinder core 2, which during locking prevents the tactile insert 17 from sliding into the cavity 6. This can also be prevented so that the tactile insert 17 acts springy in the direction of the channel of the key 8. The tactile insert 17 can be made cylindrical, or in the area of its engagement also as a cube-shaped slider.
