Predmet izumaThe subject of the invention

Predmet izuma je zasnova ključavnice z dvema soosnima zaklepnima cilindroma in s ključem za upravljanje ključavnice.The subject of the invention is the design of a lock with two coaxial lock cylinders and a key to operate the lock.

Opis znanega stanja tehnikeDescription of the prior art

Poznane so zasnove cilindričnih ključavnic s ploščatimi ključi (glej dokument EP 0211602), kjer prvo kodiranje na ožji stranici ključa upravlja prilagodilne kline, ki so nameščeni v vrtljivem cilindru v vrsti v vzdolžni ravnini žleba ključa in sodelujejo z vzmetenimi zapornimi klini, nameščenimi v ohišju ključavnice. Hkrati drugo kodiranje na drugi stranici ključa upravlja srpaste diske, ki drsijo v lokastih utorih na obodu vrtečega se cilindra proti sili povratne vzmeti. Ti diski sodelujejo z vzdolžno zaklepno palico, ki se radialno nahaja teleskopsko v cilindru in ubira v raztegnjenem zaklepnem položaju z vzdolžnim zaklepnim utorom v cilindrični votlini ohišja ključavnice. Čeprav omogočajo take zasnove relativno veliko število kombinacij, ne izključujejo možnosti nepooblaščenega odpiranja ključavnice s pomočjo tako imenovane dinamične metode (bumping), med katero zaskoki in zaporni klini nihajo zaradi udarcev aplikatorja ključa do take mere, da se ustvari delilna ravnina in s hkratnim zasukanjem cilindra jo je na koncu mogoče odpreti. Izboljšan sestav cilindrične ključavnice, ki je odpornejša na dinamično odpiranje, je opisan v češkem patentu s skrajšanim trajanjem CZ 20509. Izboljšava je bila dosežena s pomočjo specifičnega oblikovanja srpasto oblikovanih diskov (zaskokov) in z njihovim sodelovanjem s stenami cilindrov in z ohišjem, vključno z vzdolžno zaklepno palico. Na zanesljivo delovanje ključavnične sklopke pa neugodno vpliva večja obraba konice ključa, ki se po vstavitvi v cilinder neposredno prilega zaustavljalni površini telesa sklopke in potiska sklopko v upravljalno brado ključavnice.Designs of cylindrical locks with flat keys are known (see document EP 0211602), where the first encoding on the narrow side of the key manages adaptive wedges mounted in a rotating cylinder in a row in the longitudinal plane of the key groove and cooperating with spring locking wedges mounted in the lock housing . At the same time, the second encoding on the other side of the key controls the sickle disks, which slide in elbow grooves on the circumference of the rotating cylinder against the force of the return spring. These disks interact with a longitudinal locking rod radially located telescopically in the cylinder and harvested in the extended locking position by a longitudinal locking groove in the cylindrical cavity of the lock housing. Although such designs allow for a relatively large number of combinations, they do not exclude the possibility of unauthorized opening of the lock by the so-called dynamic bumping method, during which the latches and locking wedges oscillate due to the impact of the key applicator to such a degree that a dividing plane is created and the cylinder is rotated it can eventually be opened. An improved dynamic lock opening cylindrical lock assembly is described in the Czech patent of shortened duration CZ 20509. The improvement has been achieved through the specific design of sickle-shaped disks (snaps) and their cooperation with cylinder walls and housing, including longitudinal locking stick. However, the reliable operation of the locking clutch is adversely affected by the increased wear on the key tip, which, after insertion into the cylinder, directly fits into the stopping surface of the clutch body and pushes the clutch into the lock control beard.

Povzetek izumaSummary of the Invention

Predmet tega izuma sta ključavnica in ključ, kjer ima ključavnica dva soosna zaklepna cilindra, ki sta vsak uležajen v svojem ohišju, med katerima se nahaja osno uležajena upravljalna brada ključavnice, pri čemer sta obe ohišji med seboj povezani z mostom v spodnjem delu. Oba cilindra sta tudi držana skupaj s pomočjo varnostnih vezi in za upravljanje ključavnice sta vsak posamično opremljena s sklopko, ki je hkrati vstavljena • · v os vrtenja telesa upravljalne brade, kjer drsi, a ni vrtljivo uležajena proti upravljalni bradi. Princip izuma je v tem, da lokasti radialni utori, ki so razporejeni vzdolž cilindričnega telesa cilindra, vsebujejo vsaj eno vrsto vzmetenih srpastih diskov, ki drsijo v teh radialnih utorih s pomočjo svojih izboklin, ki se nahajajo na zunanji strani vsake lamele in segajo v notranje radialne utore v ohišju, kjer so te izbokline kotno zamaknjene druga od druge in sodelujejo z osnimi utori v notranji cilindrični površini ohišja. Število in kotni zamik osnih utorov ustreza številu in kotnemu zamiku izboklin. Pomik izboklin posameznih diskov v ustrezen osni utor upravlja prvo kodiranje, izvedeno na eni strani grebena ali v ustrezni bočni strani ploščatega ključa ključavnice, v katero se lamela gibko potisne, potem ko smo ključ vstavili v ključavnico. Da bi preprečili vrtenje cilindra po tem, ko je bil vstavljen pooblaščeni ploščati ključ, je v cilinder v območju notranjega konca tega cilindra vstavljen omejevalni klin; zunanji štrleči del omejevalnega klina je razmeščen tako, da drsi v vzdolžnem utoru, ki je izveden v ohišju in gre - v smeri proti upravljalni bradi - v radialni utor ohišja. V funkcionalnem položaju, potem ko je bil vstavljen pooblaščeni ploščati ključ, v katerem so vsi diski obrnjeni tako, da se njihove zunanje izbokline ujemajo z vzdolžnimi osnimi utori in potem, ko je cilinder potisnjen v ključavnico zaradi učinka zaustavljalnega dela stebla ploščatega ključa, se omejevalni klin osnega pomika cilindra nahaja v radialnem utoru ohišja v določenem osnem položaju za kasnejše vrtenje cilindra v ključavnici.The object of the present invention is a lock and key, where the lock has two coaxial locking cylinders, each mounted in its housing, between which there is an axially locked lock control beard, both housings being interconnected by a bridge at the bottom. Both cylinders are also held together by means of safety ties and are operated individually with a clutch to operate the lock, which is at the same time inserted into the pivot axis of the control beard, where it slides but is not pivotally mounted against the control beard. The principle of the invention is that the arched radial grooves arranged along the cylindrical body of the cylinder contain at least one series of spring sickle disks, which slide in these radial grooves by means of their projections, which are located on the outside of each lamella and extend into the inner radial grooves in the housing where these projections are angularly displaced from one another and interact with axial grooves in the inner cylindrical surface of the housing. The number and angular displacement of the axial grooves corresponds to the number and angular displacement of the projections. The displacement of the projections of the individual disks into the corresponding axial groove is governed by the first encoding, performed on one side of the ridge or in the corresponding lateral side of the flat key of the lock, into which the blade is flexibly pushed after the key has been inserted into the lock. In order to prevent the cylinder from rotating after an authorized flat key has been inserted, a restraining wedge is inserted into the cylinder in the area of the inner end of that cylinder; the outer projecting portion of the restraining wedge is arranged so that it slides in a longitudinal groove, which is made in the housing and goes - in the direction of the control beard - into the radial groove of the housing. In the functional position, after an authorized flat key has been inserted in which all the disks are rotated so that their outer projections are aligned with the longitudinal axial grooves and after the cylinder is pushed into the lock due to the stopping effect of the flat key stem, the pivot pin of the cylinder is located in the radial groove of the housing in the specified axial position for later rotation of the cylinder in the lock.

Z zasnovo ključavnice po tem izumu je odpravljena težava z nepooblaščenim vdorom v ključavnico s pomočjo zgoraj opisane dinamične metode (bumpinga). Za razliko od klasične konstrukcije cilindra, kjer se sklopka aktivira (medsebojna povezava sklopke z upravljalno brado ključavnice) s pomikom ključa, se tukaj aktivacija izvede šele po kasnejšem osnem pomiku cilindra v ključavnico zaradi učinka zaustavljalnega dela stebla pooblaščenega ključa. Tako na zanesljivo delovanje sklopke ne vpliva obraba konice ključa, kot na primer pri lamelnih ključavnicah na zaganjalnikih motornih vozil.The design of the lock according to the invention eliminates the problem of unauthorized intrusion into the lock by using the dynamic bumping method described above. Unlike the classic cylinder construction, where the clutch is actuated (interconnecting the clutch with the lock control beard) with the key displacement, the actuation is carried out only after the lateral axial displacement of the cylinder into the lock due to the stopping effect of the authorized key stem. Thus, the reliable operation of the clutch is not affected by the wear of the key tip, such as in the case of lamellae locks on motor vehicle starters.

V alternativni izvedbi te ključavnice vsebujejo lokasti radialni utori cilindričnega telesa cilindra dve vrsti drsno vodljivih vzmetenih diskov z izboklinami, ki so razporejene ena nasproti drugi in sodelujejo z osnimi utori v notranji cilindrični površini ohišja; diske vsake vrste upravlja prvo oziroma drugo kodiranje ključa, ki se vstavlja, in je tudi izvedeno dvostransko na straneh grebena ali na bočnih straneh ključa. S tem se • · poveča število kombinacij in varnost ključavnice.In an alternative embodiment, these locks comprise the radial grooves of the cylindrical body of the cylinder two rows of sliding-guided spring disks with projections opposite each other and cooperating with axial grooves in the inner cylindrical surface of the housing; disks of each type are controlled by the first or second encoding of the key being inserted, and is also executed bilaterally on the sides of the ridge or on the sides of the key. This increases the number of combinations and security of the lock.

Osno pomikanje cilindra v ključavnici deluje proti pritisku vzmeti cilindra, katerega drugi konec nalega na rebro upravljalne brade ključavnice. Tako je olajšano upravljanje cilindra.The axial movement of the cylinder in the lock acts against the pressure of the cylinder spring, the other end of which rests on the rib of the control chin of the lock. This makes it easier to operate the cylinder.

Po enem od možnih izvedbenih primerov te ključavnice ima ploskev notranjega konca cilindra prečno zarezo, ki vsebuje drsno, ploščici podobno telo sklopke, ki je trajno potisnjeno proti rebru upravljalne brade. Telo sklopke ima vzdolžno zarezo, ki je odprta v smeri proti rebru upravljalne brade, kjer klin omejevala raztezanja sklopke sega v to zarezo in omejuje končni osni položaj sklopke.According to one possible embodiment of this lock, the surface of the inner end of the cylinder has a transverse notch containing a sliding, tile-like clutch body which is permanently pushed against the rib of the control beard. The clutch body has a longitudinal notch open in the direction of the rib of the control chin, where the wedge restricts the clutch extensions extending into this notch and limits the end axial position of the clutch.

Po drugem izvedbenem primeru te ključavnice zgornji konci radialnih gredi, ki so razporejene v vrsti, vodijo v žleb ključa v cilindru. V radialnih gredeh so drsno uležajeni prilagodilni klini, katerih zgornji konci sodelujejo s tretjim kodiranjem, izvedenim na spodnji, ožji strani ploščatega ključa in proti spodnjim koncem katerih nalegajo zgornje ploskve zapornih klinov, ki so vzmeteni v izvrtinah v ohišju, soosno z ustreznimi gredmi v cilindru v funkcionalnem zaklepnem položaju cilindra. Ta pomožni klasični pripomoček ključavnice zopet poveča število kombinacij in s tem varnost.According to another embodiment of this lock, the upper ends of the radial shafts arranged in a row lead to a key groove in the cylinder. In the radial beams there are sliding bearing adaptation wedges, the upper ends of which cooperate with the third encoding made on the lower, narrower side of the flat key and against the lower ends of which the upper surfaces of the locking wedges, which are suspended in the holes in the housing, are aligned with the corresponding shafts in the cylinders. in the cylinder’s functional lock position. This auxiliary classic lock accessory again increases the number of combinations and thus the security.

Predmet tega izuma vključuje tudi ploščati ključ, ki je sestavljen iz glave, razširjenega prehodnega dela in stebla, kjer je vsaj ena od obeh stranskih ploskev ali pa obe strani grebena stebla opremljena s prvim ali drugim kodiranjem in ožji spodnji del ključa je lahko opremljen s tretjim kodiranjem za upravljanje nekaterih izvedb zgoraj opisane ključavnice. Zaustavljalni del tega ključa je sestavljen iz sredstva, izbranega iz skupine, ki vključuje, posamično ali v kombinaciji, spodnjo ploskev prehodnega razširjenega dela, vsaj eno bočno izboklino v tem prehodnem razširjenem delu ali ploskev prehodnega razširjenega dela, ki se razteza proti stranem.The object of the present invention also includes a flat key consisting of a head, an extended transitional part and a stem, wherein at least one of the two lateral surfaces or both sides of the stem ridge is provided with a first or second coding and the narrower lower part of the key may be provided with a third coding to manage some embodiments of the lock described above. The stopping portion of this key consists of an agent selected from the group comprising, individually or in combination, the lower surface of the transitional enlarged portion, at least one lateral protrusion in this transitional expanded portion, or the surface of the transitional expanded portion extending toward the sides.

Odklepanje cilindra ključavnic poteka v treh stopnjah, ki vključujejo vstavljanje ključa, dodatno premikanje za vstavljanje celotnega cilindra z vstavljenim ključem v ohišje, kadar se izvaja osna sila zaradi učinka zaustavljalnega dela ključa, in na koncu obračanje cilindra z izvajanjem momenta na vstavljeni ključ.The unlocking of the cylinder lock is done in three stages involving the insertion of the key, additional movement to insert the entire cylinder with the key inserted into the housing when the axial force is exerted by the effect of the stopping part of the key, and finally turning the cylinder by applying torque to the inserted key.

The angular offset of these axial grooves 14 corresponds to the angular offset of the outer projections 13 of the sickle-shaped disks 11. The outer arched sides of the disks 11 are adjacent to the wall of the cylindrical cavity of the housing 2, and part of the inner arched wall of the part of each lamella 11 extends through the bottom of the corresponding arched radial groove 12. The displacement of the blade 11 is accomplished by the first coding 15 executed on the side of the flat key stem 7 into which the blade spring 16 pushes one end of the sickle blade 11 (one of the outer projections 13 is located at its opposite end). The spring 16 is located in the recess 17 in the cylinder 1 and its outer end rests on the bulge 18 on the inner circumference of the louver 11.

Za še dodatno povečanje števila kombinacij (zapiranj lamel) ključavnice je lahko na obeh straneh cilindra 1 izveden omenjeni niz diskov 11, ki so posamično drsno uležajeni v lokastih radialnih utorih 12 cilindričnega telesa cilindra 1 (slika 4). Pomik diskov 11, ki se nahajajo na drugi bočni strani cilindra 1, upravlja drugo kodiranje 19, ki je izvedeno v bočni strani stebla ploščatega ključa 7 (na nasprotni strani stebla ploščatega ključa 7).To further increase the number of locks (locks) of the lock, the aforementioned set of disks 11 can be made on both sides of cylinder 1, which are individually slidably mounted in the elbow radial grooves 12 of the cylindrical body of cylinder 1 (Figure 4). The displacement of the disks 11 located on the other side of the cylinder 1 is governed by the second encoding 19, which is implemented in the side of the flat key stem 7 (opposite the flat key stem 7).

Medtem ko se odklepanje običajnega cilindra izvaja v dveh korakih, se pravi vstavljanje ključa in obračanje cilindra z izvajanjem momenta na vstavljeni ključ, zahteva zasnova o tem izumu še en premik, namreč vstavljanje celotnega cilindra v ohišje. Ko je vstavljen pooblaščeni ključ in se je ustvarila delilna ravnina med zaskoki (prilagodilnimi klini 8) in zapornimi klini 10 v vseh izvrtinah (radialnih gredeh), se cilinder 1 premakne (z izvajanjem osne sile na zaustavljalni del ključa 7) v položaj v ohišju 2, ki bo omogočal zasukanje cilindra 1 z izvajanjem momenta na vstavljeni ključ 7. V tem položaju se posamični diski 11 obrnejo v ustrezne lokaste radialne utore 12 do položaja, kjer se zaradi učinka grebena ali stranskih izboklin na steblo ključa 7 (prvo ali drugo kodiranje 15, 16) njihove zunanje izbokline 13 prilegajo v ustrezne osne utore 14 v notranji cilindrični površini ohišja 2. Cilinder 1 se potem potisne noter zaradi delovanja zaustavljalnega dela ključa 7. Šele ko je cilinder 1 popolnoma vstavljen v ključavnico, se sklopka 4 potisne v upravljalno brado 5 (v zarezo v njenem rebru) in ko se potem cilinder 1 zasuka, se z njim vred zasuka tudi upravljalna brada 5.While the unlocking of a normal cylinder is performed in two steps, i.e. inserting a key and turning the cylinder by exerting torque on the inserted key, the design of the present invention requires another shift, namely inserting the entire cylinder into the housing. When an authorized key is inserted and a dividing plane is created between the latches (adjusting wedges 8) and the locking wedges 10 in all bores (radial beams), the cylinder 1 moves (by applying axial force to the stop part of the key 7) to the position in the housing 2 , which will allow the cylinder 1 to be rotated by applying a torque to the inserted key 7. In this position, the individual disks 11 are rotated into the corresponding radial grooves 12 to the position where, due to the effect of the ridge or lateral projections, the key 7 (first or second coding 15) , 16) their outer projections 13 fit into the corresponding axial grooves 14 in the inner cylindrical surface of the housing 2. Cylinder 1 is then pushed in due to the operation of the locking part of the key 7. Only when cylinder 1 is fully inserted into the lock, the clutch 4 is pushed into the control beard 5 (a notch in its rib) and when the cylinder 1 is rotated, the control beard 5 is also twisted.

Za osno premikanje cilindra 1 z vstavljenim ključem 7 proti upravljalni bradi 5 je torej treba premakniti zaskoke v položaj, kjer so vsi zaporni klini 10 popolnoma vstavljeni v ohišje 2 cilindra 1 (ustvari se delilna ravnina) in so hkrati vsi srpasto oblikovani diski 11 obrnjeni tako, da se njihove zunanje izbokline 13, ki segajo v notranje radialne utore 20 v ohišju 2, ujamejo z osnimi utori 14 v notranji cilindrični površini ohišja 2. Število notranjih radialnih utorov 20 v ohišju 2 je dvakrat večje od števila bližnjih lokastih radialnih utorov 12 cilindričnega telesa cilindra 1.In order to move the cylinder 1 axially with the key 7 inserted against the control beard 5, it is therefore necessary to move the locks to a position where all the locking wedges 10 are fully inserted into the housing 2 of the cylinder 1 (dividing plane is created) and at the same time all the sickle-shaped disks 11 are turned so , that their outer projections 13 extending into the inner radial grooves 20 in the housing 2 are caught by the axial grooves 14 in the inner cylindrical surface of the housing 2. The number of internal radial grooves 20 in the housing 2 is twice the number of nearby localized radial grooves 12 of the cylindrical cylinder bodies 1.

Za preprečevanje vrtenja cilindra 1 potem, ko je bil vstavljen pooblaščeni ključ 7, vsebuje cilinder 1 omejevalni klin 21, katerega navzven štrleči del drsi v vzdolžnem utoru 22, izvedenem v ohišju 2. Ta utor 22 omejuje dolžino osnega pomika cilindra 1 z vstavljenim ključem 7 v smeri proti upravljalni bradi 5. V smeri proti upravljalni bradi 5 gre v radialni utor 23 ohišja 2, ki omogoča vrtenje cilindra 1 v ohišju 2, ko je bil potisnjen v ključavnico v točno definiranem osnem položaju. Za lažje upravljanje ključavnice je lahko cilinder 1 vzmeten v osni smeri (njegovo osno gibanje deluje proti pritisku vzmeti 27 cilindra, katerega drugi konec nalega na rebro upravljalne brade 5 ključavnice). Ploskev notranjega konca cilindra 1 ima prečno zarezo 24, ki vsebuje drsno, ploščici podobno telo sklopke 4, ki ga dve vzmeti 28 telesa sklopke trajno potiskata proti rebru upravljalne brade 5 ključavnice, ki ima zarezo za prehod sklopke 4, ko ubira z upravljalno brado 5. Odprtina cilindra 1 v območju njegovega notranjega konca vsebuje zatič 25 omejevala raztezanja sklopke 4. Ploščici podobno telo sklopke 4 ima vzdolžno zarezo, ki je odprta v smeri proti rebru upravljalne brade 5, in zatič 25 omejevala raztezanja sklopke 4, ki omejuje njen končni osni položaj, sega v to zarezo.To prevent the cylinder 1 from rotating after the authorized key 7 has been inserted, the cylinder 1 has a restraining wedge 21 whose outward projecting portion slides in a longitudinal groove 22 made in the housing 2. This groove 22 limits the length of the axial displacement of the cylinder 1 with the inserted key 7 in the direction of the control beard 5. In the direction of the control beard 5, it goes into the radial groove 23 of the housing 2, which allows rotation of the cylinder 1 in the housing 2 when it was pushed into the lock in a well-defined axial position. For ease of operation of the lock, cylinder 1 can be sprung in the axial direction (its axial motion acts against the pressure of the spring 27 of the cylinder, the other end of which rests on the rib of the control chin 5 of the lock). The inner end surface of the cylinder 1 has a transverse notch 24 comprising a sliding, clutch-like clutch body 4 which is permanently pushed by two springs 28 of the clutch body against the edge of the control beard 5 of the lock, which has a notch for the clutch passage 4 when engaging with the control beard 5 The opening of the cylinder 1 in the region of its inner end comprises a clutch extension stop pin 25. A clutch-like clutch body 4 has a longitudinal notch open in the direction of the rib of the control chin 5, and a clutch extension limiter pin 25 limiting its end axis. position, goes into that notch.

Kot je bilo opisano zgoraj, se odklepanje cilindra 1 ključavnice po tem izumu izvaja v treh korakih, ki vključujejo vstavljanje ključa, dodatno premikanje za vstavljanje celotnega cilindra 1 z vstavljenim ključem v ohišje 2 in na koncu vrtenje cilindra z izvajanjem momenta na vstavljeni ključ. Osna sila pri vstavljanju celotnega cilindra 1 z vstavljenim ključem v ohišje 2 se povzroči z učinkom zaustavljalnega dela gredi 26 ključa 7, ki je lahko sestavljen iz spodnje ploskve prehodnega razširjenega dela pri glavi ključa, vsaj ene stranske izbokline v tem prehodnem razširjenem delu ali ploskve prehodnega razširjenega dela, ki se razteza proti stranem, ali kombinacij le-teh.As described above, the unlocking of the cylinder 1 of the lock according to the invention is performed in three steps involving the insertion of a key, further movement to insert the entire cylinder 1 with the key inserted into the housing 2 and finally rotate the cylinder by performing a torque on the inserted key. The axial force when inserting the complete cylinder 1 with the key inserted into the housing 2 is caused by the effect of the stopping part of the shaft 26 of the key 7, which may consist of a lower surface of the transitional extended portion at the key head, of at least one lateral protrusion in this transitional extended portion or of the transitional surface the extended side-extending part, or combinations thereof.

Ključavnica po tem izumu ima veliko število možnih kombinacij in je v bistvu odporna proti nepooblaščenemu odklepanju s pomočjo dinamične metode (bumpinga).The lock of the present invention has a large number of possible combinations and is essentially resistant to unauthorized unlocking by means of a dynamic method (bumping).
