Abstract

The discussed mechanism enables the leafing through papers in its open position with the operating lever (4) in such position of the mechanism that it does not hinder the relocation of sheets from the spire-shaped holder (21, 22) of one stirrup (2) to spire-shaped holders (31, 32) of the remaining stirrup (3) or vice versa. The leafing through is in this respect completely unhindered even with a completely full file regardless of the fact whether this one is open or closed. Apart from that the mechanism according to the invention features on its baseplate (1) both rotating stirrups (2, 3) with both pairs of spire-shaped holders (21, 22; 31, 32) which results in the distance between the interactive spire-shaped holders (21, 31; 22, 32) in the open position being considerably larger than with classical mechanisms. Correspondingly the mechanism according to the invention can hold without any problems a thicker pile of papers or such pile can be removed from the file at the same time.

Mehanizem za vpenjanje listov v registrator ali podoben pripomoček za urejanje in odlaganje dokumentovA mechanism for clamping sheets into a binder or similar utility for editing and depositing documents

Izum spada na področje knjigoveštva in pripomočkov za vpenjanje oz. shranjevanje dokumentov, namreč na področje pripomočkov za urejanje in odlaganje dokumentov, zlasti takšnih, ki obsegajo sredstvo za uprijemanje v luknje, s katerimi so opremljeni za vpenjanje predvideni dokumenti, namreč dvodelni vpenjalni sklop, obsegajoč nepremakljiv del z vsaj dvema trnoma ter premakljiv del s prav tako vsaj dvema trnoma.The invention falls within the field of bookbinding and clamping aids. the storage of documents, namely, in the field of document editing and depositing aids, in particular those comprising a means of clamping down the holes with which the documents provided for clamping are provided, namely a two-part clamping assembly comprising a fixed part with at least two mandrels and a movable part with thus at least two thorns.

Pri tem je izum osnovan na problemu, kako zasnovati mehanizem za vpenjanje listov v registrator ali podoben pripomoček za urejanje in odlaganje dokumentov, ki bo omogočal listanje v odprtem položaju, pri čemer bo tudi pri povsem napolnjenem v odprtem ali zaprtem stanju registratorju listanje lahko potekalo neovirano, in pri katerem bo nadalje razdalja med vsakokrat sodelujočima trnoma z vpenjanje listov v razprtem stanju v primerjavi z doslej uporabljanimi registratorji lahko znatno večja, s čimer bo vstavljanje debelejšega svežnja listov v registrator ali odstranjevanje takšnega svežnja iz registratorja znatno olajšano.The invention is based on the problem of how to design a mechanism for clamping sheets in a binder or a similar document editing and depositing tool that will allow scrolling in the open position, while even when the register is fully filled in the open or closed state, the scrolling can be done without hindrance , and in which the distance between the cooperating webs in each case will be significantly larger by clamping the leaves in the open state than the registers used so far, making it easier to insert a thicker stack of leaves into the binder or remove such a bundle from the binder.

Doslej znan in uporabljan vpenjalni mehanizem registratorja je opisan v WO 20/04082961 oz. EP 1 606 122. Tovrstni mehanizem sestoji iz osnovne plošče, na kateri je na voljo dvojica z omenjeno ploščo togo povezanih nepremakljivih trnov, obenem pa tudi dvojica na omenjeni osnovni plošči zavihtljivo uležiščenih trnov, ki sta med seboj povezana preko ustrezno togega vmesnega odseka in zatorej oba hkrati premakljiva s pomočjo ustrezne ročice, kije uležiščena na nosilcu, kije predviden približno v osrednjem območju osnovne plošče in predstavlja del slednje oz. je s slednjo togo povezan.The known and used clamping mechanism of the binder so far is described in WO 20/04082961 or. EP 1 606 122. Such a mechanism consists of a base plate having two rigidly connected rigid mandrels with said plate and two on said base plate of pivotally spaced mandrels, which are connected to each other via a properly rigid intermediate section and therefore both are movable at the same time by means of a suitable arm, which is mounted on a support, which is provided approximately in the central region of the base plate and forms part of the latter or. is rigidly connected to the latter.

Osnovna plošča obsega ustrezne ojačitve in odprtine za pritrditev na vsakokrat razpoložljive platnice registratorja. V dveh vogalnih območjih ene od daljših stranic te plošče sta nanjo vsak zase togo pričvrščena med seboj na ustreznem odmiku razporejena nepremakljiva trna, katerih prosta konca sta ukrivljena v smeri proti prostima koncema premakljivih trnov. V območju preostale daljše stranice sta v pripadajočih ležiščih pričvrščena premakljiva trna, ki sta med seboj povezana preko vmesnega odseka, ki je prekrivljen trapezno oz. kot črka U. Omenjeni ležišči se praviloma nahajata v bližini vzdolžnega roba osnovne plošče, medtem ko je osrednje območje vmesnega odseka, preko katerega sta med seboj povezana premakljiva trna, pomaknjeno v notranjost t.j. proti osrednjemu območju osnovne plošče in poteka vzporedno s prej omenjenem robom plošče.The baseplate includes appropriate reinforcements and openings for mounting on the available registrar covers. In the two corners of one of the longer sides of this panel, each of them is rigidly fixed to each other at a suitable distance by a fixed motion, the free ends of which are curved in the direction of the free ends of the movable mandrels. In the area of the rest of the longer side, movable spikes are attached in their respective beds, which are connected to each other via an intermediate section, which is covered by a trapezoidal or. as letters U. The said beds are generally located near the longitudinal edge of the baseplate, while the central area of the intermediate section through which the movable mandrel is connected is displaced in the interior i.e. towards the central region of the baseplate and running parallel to the aforementioned edge of the plate.

Nadalje je vsaj približno v osrednjem območju osnovne plošče na voljo nosilec, ki štrli iz ravnine osnovne plošče vsaj v bistvu pravokotno glede na omenjeno ravnino ter na svojem prostem koncu na odmiku od osnovne plošče tvori vrtišče ročice za upravljanje vpenjalnega sklopa in s tem nagibanje premakljivih trnov mehanizma glede na osnovno ploščo oz. nepremakljiva trna. Omenjena ročica je razporejena v vertikalni ravnini, ki je vzporedna z omenjenima vzdolžnima roboma osnovne plošče, os uležiščenja omenjene ročice pa poteka skozi omenjeni nosilec v smeri pravokotno glede na omenjena vzdolžna robova osnovne plošče in vzporedno z ravnino osnovne plošče. Nadalje je na omenjeni ročici na ustreznem odmiku od vrtišča ekscentrično uležiščen kotalčni element, ki je prirejen za kotaljenje po omenjenem osrednjem območju vmesnega odseka med obema premakljivima trnoma. V ta namen je ročica izvedena v obliki črke L, pri čemer njen daljši krak predstavlja upravljalni krak, na koncu krajšega kraka je uležiščen kotalčni element, v presečišču krakov pa je uležiščena sama ročica.Further, at least about at least in the central region of the baseplate there is a support projecting from the plane of the base plate at least substantially perpendicular to said plane and at its free end at a distance from the base plate to form a pivot of the lever for controlling the clamping assembly and thereby tilting the movable mandrels mechanism with respect to the base plate or. immutable thorn. Said lever is arranged in a vertical plane parallel to said longitudinal edges of the base plate, and the axis of bearing of said lever extends through said carrier in a direction perpendicular to said longitudinal edges of the base plate and parallel to the plane of the base plate. Further, on the said lever, at an appropriate distance from the pivot, is an eccentrically mounted roller element adapted for rolling along said central region of the intermediate section between the two movable webs. For this purpose, the lever is L-shaped, with the longer arm being the control arm, the rolling element at the end of the shorter arm, and the arm itself at the intersection of the arms.

Vpenjalni sklop je v območju vmesnega odseka podprt z vzmetjo ki je na voljo kot v ustreznem izrezu v osnovni plošči konzolno vpeta upogibna listna vzmet. Zahvaljujoč vihtenju ročice vzdolž omenjenega osrednjega odseka premakljiv kotalčni element po izbiri bodisi pritiska vmesni element proti sili omenjene vzmeti oz. dopušča, da omenjena vzmet odriva osrednji odsek, kolikor pač to vsakokrat dopušča omenjen kotalčni element v odvisnosti od vsakokrat razpoložljivega položaja ročice, pri čemer se premakljiva kraka nagibata glede na ravnino osnovne plošče in s tem bodisi približujeta nepremakljivima krakoma ali se od njiju oddaljujeta.The clamping assembly is supported by a spring in the region of the intermediate section, which is available as in the corresponding recess in the base plate a cantileverly bent leaf spring. Thanks to the swinging of the lever along the said central section, the movable roller element is optionally either depressed by the intermediate element against the force of said spring or. permits said spring to dislodge the central portion, as far as the rolling element permits, in each case, depending on the position of the lever in each case, with the movable arms tilting relative to the plane of the base plate, thereby either approaching or moving away from the movable arms.

Kadar sta premakljiva trna odklonjena vstran od dvojice nepremakljivih trnov, je mehanizem odprt in v takem položaju je možno v registrator vstavljati oz. iz njega odstraniti liste. Vmesni odsek premakljivih krakov je zahvaljujoč vzmeti odrinjen vstran od osnovne plošče, upravljalni krak ročice je prav tako odklonjen vstran od osnovne plošče in sega v območje med razprtima nepremakljivim in premakljivim trnom, ki se nahajata na strani omenjenega upravljalnega kraka ročice.When the movable spikes are deflected away from the two fixed spikes, the mechanism is open and in such a position it is possible to insert or insert into the binder. remove leaves from it. The intermediate section of the movable arms is, thanks to the spring, pushed away from the base plate, the control arm of the lever is also deflected away from the base plate and extends into the area between the open fixed and movable mandrel located on the side of said control arm of the lever.

S premikom upravljalnega kraka ročice v smeri proti ravnini osnovne plošče se kotalčni element premakne vzdolž osrednjega območja vmesnega odseka med premakljivima krakoma in pritisne omenjeno osrednje območje v smeri proti ravnini osnovne plošče in torej proti sili vzmeti. Ko kotalčni element prečka linijo, ki poteka pravokotno glede na ravnino osnovne plošče skozi vrtišče ročice na osrednjem nosilcu, se prosti konec vsakokratnega premakljivega trna soosno prisloni ob prosti konec vsakokrat pripadajočega nepremakljivega trna. Ker ročica omogoča še nadaljnji premik kotalčnega elementa preko prej omenjene linije, se ročica v takem položaju zaskoči in v takem položaju tudi obstane, s čimer je mehanizem zaprt.By moving the lever control lever in the direction toward the plane of the base plate, the rolling element moves along the central region of the intermediate section between the movable arms and presses said central region in the direction towards the plane of the base plate and therefore against the force of the spring. When the rolling element crosses a line perpendicular to the plane of the base plate through the pivot of the crank on the center bracket, the free end of each movable mandrel coaxially rests against the free end of each adjacent movable mandrel. As the lever allows further movement of the rolling element over the aforementioned line, the lever locks in this position and stays in this position, thus closing the mechanism.

Tovrstni mehanizem je nedvomno zelo zanesljiv in učinkovit, saj omogoča hitro in zanesljivo vpenjanje tudi razmeroma velikega števila listov. Problem nastopi, kadar uporabnik želi listati vpete liste ali npr. preurejati vsebino registratorja, še zlasti npr. zamenjati vrstni red vpetih listov ali podobno. V takem primeru je listanje t.j. premikanje listov iz območja nepremakljivih trnov v območje premakljivih trnov ali obratno, sicer možno, vendar pod pogojem, daje mehanizem zaprt. Za spreminjanje vrstnega reda listov pa je treba z odvihtenjem ročice trne razpreti in začasno odstraniti liste ter jih nato ponovno vstaviti v drugačnem vrstnem redu, zatem pa z vihtenjem ročice in nagibom premakljivih trnov ponovno zapreti mehanizem. V primeru sortiranja v registrator vpetih listov je pogosto potrebno zaporedje teh korakov večkrat ponoviti, kar je razmeroma zamudno in za uporabnika neudobno. Razen tega je razdalja med vsakokrat sodelujočima nepremakljivim in premakljivim trnom tudi ob povsem odvihtenem vpenjalnem sklopu razmeroma majhna, kar je v primeru vstavljanja debelejšega svežnja listov v registrator ali odstranjevanja takšnega svežnja iz registratorja lahko zelo moteče oz. je vstavljanje ali odstranjevanje tovrstnega svežnja neredko celo nemogoče.This mechanism is undoubtedly very reliable and efficient, as it enables fast and reliable clamping of a relatively large number of leaves. The problem arises when the user wants to scroll through clamped sheets or e.g. rearrange the contents of the binder, especially e.g. change the order of pinned leaves or the like. In such a case, the scrolling i.e. movement of leaves from the area of fixed spines to the region of movable spines or vice versa, otherwise possible, but provided that the mechanism is closed. However, in order to change the order of the leaves, it is necessary to open and temporarily remove the leaves by unscrewing the mandrel and then reinserting them in a different order, then closing the mechanism by swinging the handle and tilting the movable mandrels. In the case of sorted sheets, it is often necessary to repeat the sequence of these steps several times, which is relatively time-consuming and uncomfortable for the user. In addition, the distance between the two non-moving and movable hooks involved in each case is relatively short, even if the clamping assembly is completely loosened, which can be very annoying or unsettling when inserting a thicker bundle of leaves into the binder. it is quite often impossible to insert or remove such a stack.

EP 1 226 987 predlaga v osnovi podoben mehanizem, pri katerem je spet na voljo osnovna plošča z na sebi togo pričvrščenima nepremakljivima trnoma in osrednjim nosilcem, na katerem se nahaja vrtišče ročice. Premakljiva trna sta spet zavihtljivo uležiščena na osnovni plošči in med seboj povezana z vmesnim odsekom, katerega osrednje območje je v smeri proti ravnini osnovne plošče pritisnjeno s pomočjo na ročici ekscentrično uležiščenega kotalčnega elementa, obenem pa je omenjeni vmesni odsek spet odrinjen iz ravnine osnovne plošče s pomočjo vzmeti, kije vgrajena na osnovni plošči pod omenjenem osrednjim območjem vmesnega odseka.EP 1 226 987 proposes a substantially similar mechanism in which a base plate is again available with rigidly fixed fixed braces and a central support on which the pivot of the lever is located. The movable spikes are again pivotally supported on the base plate and interconnected by an intermediate section whose central region is pressed in the direction towards the plane of the base plate by the eccentrically spaced roller element on the lever, and at the same time said intermediate section is again pushed out of the plane of the base plate by by means of springs mounted on the base plate below said central region of the intermediate section.

Namen tovrstne rešitve je omogočiti listanje ali preurejanje, npr. spreminjanje zaporedja v registrator vpetih listov, tudi v primeru kadar je mehanizem odprt. S tem namreč tudi pri zahtevnejšem razvrščanju odpade potreba po večkratnem odpiranju oz. zapiranju mehanizma. V izogib štrlenju ročice v območje med vsakokrat nepremakljivim in pripadajočim premakljivim trnom na strani upravljalnega kraka ročice je v tem primeru zahvaljujoč prisotnosti ustreznega omejevalnega zavihka na osnovni plošči v območju neposredno ob/nad osrednjim območjem vmesnega odseka med premakljivima krakoma odvihtenje upravljalnega kraka v smeri vstran od ravnine osnovne plošče omejeno. S tem je z razmeroma preprosto modifikacijo osnovne plošče, namreč z izvedbo izreza in upogibanjem materiala tega izreza v omenjen omejevalni zavihek na učinkovit način preprečeno, da bi upravljalni krak ročice po odprtju mehanizma vstopil v območje med razprtima nepremakljivim in premakljivim krakom, kar v splošnem preprečuje listanje. Premik upravljalnega kraka ročice je zahvaljujoč omenjenemu omejevalnemu zavihku omogočen samo do te mere, da je tudi pri odprtem mehanizmu upravljalni krak še vedno držan razmeroma blizu ravnine osnovne plošče in na vsaj tolikšnem odmiku od nepremakljivega in premakljivega kraka, daje premeščenje listov še vedno neovirano.The purpose of this solution is to enable scrolling or rearranging, e.g. changing the order in the clamp register, even when the mechanism is open. This means that even with more complex sorting, there is no need for multiple openings. closing mechanism. In order to prevent the lever from projecting into the area between the non-movable and the associated movable mandrel on the side of the control arm, in this case, due to the presence of a suitable restraint tab on the base plate in the area immediately adjacent to the central area of the intermediate section between the movable arms in the direction of the control arm in the direction of the control arm the plane of the base plate is limited. In this way, by modifying the base plate relatively easily, namely by making a cut and bending the material of the cut into said restraining tab, the control arm of the lever is effectively prevented from entering the area between the open fixed and movable arm after opening the mechanism, which generally prevents scrolling. Thanks to the said limiting tab, the movement of the control arm of the lever is only possible to the extent that, even with the mechanism open, the control arm is still kept relatively close to the plane of the base plate and at least as far away from the stationary and movable arm as possible leaves the movement of the leaves unhindered.

Problem omogočanja listanja je torej v tem primeru rešen izključno na osnovi zmanjšanja hoda ročice. Ker pa se po odprtju mehanizma premakljivi in nepremakljivi trn razpreta za določeno razdaljo ob ustrezno zmanjšanem hodu ročice, se mora temu ustrezno spremeniti prenosno razmerje med silo na ročici in silo, s katero sta premakljiva tma pritisnjena proti nepremakljivima trnoma. To bodisi pomeni, da mora biti na ročici na voljo večja sila ali pa je sam mehanizem izpostavljen večjim obremenitvam in posledično tudi deformacijam.The problem of enabling scrolling is thus solved solely by reducing the stroke of the lever. However, since, after opening the mechanism, the movable and non-movable mandrel is disengaged by a certain distance with a correspondingly reduced stroke of the lever, the transmission ratio between the force on the lever and the force with which the movable tma is pressed against the non-movable mandrels must accordingly change. This either means that a greater force must be available on the lever, or the mechanism itself is subject to greater stresses and, consequently, deformation.

Ker gre za pri tovrstnih mehanizmih nedvomno za velikoserijske izdelke, ki pa vsekakor morajo ustrezati tudi ostrim zahtevam v zvezi z varno in zanesljivo uporabo, je povečanje sile zapiranja v osnovi nedopustno, povečanje deformacij pa vodi bodisi k nezanesljivosti delovanja ob krajši življenjski dobi izdelkov ali pa je povezano z drugimi ukrepi, npr. uvajanem dražjih materialov ali povečanja dimenzij sestavnih delov, kar pa je potem povezano s povečanjem teže in višjimi stroški izdelave. Tudi v tem primeru je razdalja med vsakokrat sodelujočima nepremakljivim in premakljivim trnom tudi ob povsem odvihtenem vpenjalnem sklopu razmeroma majhna, kar je v primeru vstavljanja debelejšega svežnja listov v registrator ali odstranjevanja takšnega svežnja iz registratorja lahko zelo moteče oz. je vstavljanje ali odstranjevanje tovrstnega svežnja neredko celo nemogoče.Since these mechanisms are undoubtedly large-scale products, but they must also meet the stringent requirements for safe and reliable use, increasing the closing force is fundamentally unacceptable, and increasing deformation leads either to unreliable performance or shorter product life. is related to other measures, e.g. introducing more expensive materials or increasing the dimensions of the components, which in turn is associated with an increase in weight and higher manufacturing costs. Even in this case, the distance between the non-moving and movable mandrel involved is relatively short, even if the clamping assembly is completely loosened, which can be very annoying or unsettling when inserting a thicker bundle of leaves into the binder. it is quite often impossible to insert or remove such a stack.

Še nadalje je v WO 2005/047015 opisan mehanizem registratorja, ki prav tako obsega osnovno ploščo, dvojico s slednjo togo povezanih nepremakljivih in dvojico s pomočjo ustrezne ročice premakljivih tmov. Premakljiva trna sta tudi v tem primeru zavihtljivo uležiščena na osnovni plošči in med seboj povezana z vmesnim odsekom, ki je podprt z vzmetjo, ki je vgrajena v osnovni plošči. Omenjena ročica je podobno kot v predhodno obravnavanih primerih zasukljivo uležiščena na nosilcu na osnovni plošči in prirejena za sodelovanje z omenjenim vmesnim odsekom premakljivih trnov. Vendar pa v tem primeru z omenjenim odsekom ne sodeluje npr. na ročici ekscentrično uležiščen kotalčni element, marveč značilno in v obliki vnaprej določene krivulje oblikovan okoli vrtišča potekajoč odmični obodni rob v osnovi krožno zasnovanega in centrično uležiščenega delovnega območja ročice, ki je v tem primeru zasnovana v bistvu po načelih klasične odmične gredi. Na ta način se z zasukom ročice okoli omenjenega vrtišča na vnaprej določen način v odvisnosti od kota zasuka ročice spreminja oddaljenost med vrtiščem in skrajno točko na omenjenem obodnem robu, v kateri ročica vsakokrat nalega na vmesnem odseku in slednjega odriva proti sili vzmeti. V omenjenem viru so še zlasti izpostavljeni trije možni kotni položaji ročice, in sicer prvi položaj, v katerem je pri zaprtem mehanizmu ročica zapahnjena in se nahaja v bližini ravnine osnovne plošče, kar med drugim omogoča listanje, medtem ko se v drugem položaju zahvaljujoč ugodno izbranemu prestavnemu razmerju mehanizem postopoma odpre ali zapre, pri čemer je ročica zasukana vstran od ravnine osnovne plošče in je torej listanje onemogočeno, v tretjem položaju pa je ročica zasukana praktično za 180 stopinj svojega okoli vrtišča glede na prvi položaj; v tem položaju je mehanizem odprt, zahvaljujoč legi ročice neposredno ob ravnini osnovne plošče pa je tudi v odprtem stanju mehanizma omogočeno listanje. Tudi v tem primeru je še vedno na osnovni plošči vgrajena vzmet, ki pritiska vmesni odsek med premakljivima trnoma v smeri proti odmičnemu robu ročice. Razen tega je pri tovrstni rešitvi problematično predvsem štrlenje ročice takorekoč pravokotno glede na ravnino osnovne plošče v drugem položaju. Kadar se ročica nahaja v bližini ravnine osnovne plošče, je razmeroma neizpostavljena zatikanju, udarcem in drugim možnostim poškodb. V primeru omenjenega štrlenja v smeri pravokotno glede na ravnino osnovne plošče pa je prosti konec ročice precej oddaljen od ravnine osnovne plošče in tudi od samega vrtišča ročice, zato vsakršna obremenitev ročice v smeri prečno glede na os vrtišča npr. zaradi nehotenega udarca z roko, zatikanja z rokavom ali celo padca registratorja na tla lahko povzroči izjemno visoke lokalne obremenitve in deformacije v območju vrtišča, kar privede do zračnosti ali celo do neuporabnosti mehanizma. Razen tega je za samo izvedbo tovrstne rešitve potrebno že v osnovi prirediti celotno konstrukcijsko zasnovo. To pomeni, da je potrebno razviti temu primemo oblikovano osnovno ploščo, vpenjalni sklop in ročico z ustrezno krivuljo na obodnem robu delovnega območja. To seveda tudi pomeni, da je potrebno razviti in izdelati vsa orodja in naprave, s katerimi je potem možno vršiti velikoserijsko proizvodnjo, kar je povezano z ogromnimi finančnimi vlaganji in dolgotrajnimi aktivnostmi tehnične in tudi organizacijske narave. Povrhu vsega je tudi pri tovrstnem mehanizmu razdalja med vsakokrat sodelujočima nepremakljivim in premakljivim trnom tudi ob povsem odvihtenem vpenjalnem sklopu razmeroma majhna, kar je v primeru vstavljanja debelejšega svežnja listov v registrator ali odstranjevanja takšnega svežnja iz registratorja lahko zelo moteče oz. je vstavljanje ali odstranjevanje tovrstnega svežnja neredko celo nemogoče.Further, WO 2005/047015 describes a binder mechanism, which also comprises a baseplate, a pair of rigidly coupled rigid ones, and a pair using a suitable movable tm handle. In this case, the movable spikes are also pivotally mounted on the base plate and interconnected by an intermediate section supported by a spring mounted in the base plate. Said lever is, like in the cases discussed above, pivotally mounted on a support on the base plate and adapted to cooperate with said intermediate section of the movable mandrels. However, in this case, e.g. an eccentrically positioned roller element on the crank, but a characteristic and preformed curve formed around a pivoting running circumferential edge at the base of a circularly and centrally aligned working area of the crank, which in this case is essentially based on the principles of a classical camshaft. In this way, by rotating the lever around said pivot in a predetermined manner, depending on the angle of rotation of the lever, the distance between the pivot and the end point on said circumferential edge is varied, in which the lever always rests on the intermediate section and the latter pushes against the force of the spring. The aforementioned source particularly emphasizes three possible angular positions of the lever, namely the first position in which, with the mechanism closed, the lever is locked and is located near the plane of the base plate, which enables, among other things, scrolling, while in the second position, thanks to a conveniently selected the gear ratio is gradually opened or closed by the mechanism, the lever being rotated away from the plane of the base plate and thus the leafing is disabled, and in the third position the lever is rotated practically 180 degrees around the pivot relative to the first position; In this position, the mechanism is open, and thanks to the position of the lever directly on the plane of the base plate, leafing is also possible in the open state of the mechanism. Even in this case, a spring is still mounted on the base plate, which presses the intermediate section between the movable webs towards the camshaft edge. In addition, the projection of the lever is almost perpendicular to the plane of the base plate in the second position. When the lever is located near the plane of the baseplate, it is relatively exposed to pinching, knocking and other damage. In the case of said projection in a direction perpendicular to the plane of the base plate, the free end of the lever is substantially distant from the plane of the base plate and also from the pivot of the lever itself. Inadvertent kicking, sticking with the sleeve, or even falling of the binder to the floor can cause extremely high local loads and deformations in the area of the pivot, resulting in breathability or even inapplicability of the mechanism. In addition, in order to implement such a solution, it is essential to adapt the entire structural design. This means that it is necessary to develop a suitable base plate, clamping assembly and a handle with a corresponding curve at the peripheral edge of the working area. This, of course, also means that it is necessary to develop and produce all the tools and devices that can then be used for large-scale production, which is associated with huge financial investments and lengthy activities of a technical as well as organizational nature. Moreover, even with such a mechanism, the distance between the non-moving and movable mandrel involved is relatively small, even if the clamping assembly is completely loosened, which can be very annoying or unnecessary when inserting a thicker bundle of leaves into the binder. it is quite often impossible to insert or remove such a stack.

Izum se nanaša na mehanizem za vpenjanje listov v registrator ali podoben pripomoček za urejanje in odlaganje dokumentov. Tovrsten mehanizem sestoji iz osnovne plošče in vsaj dveh parov trnov, ki so med seboj razmaknjeni za vnaprej določeno razdaljo v smeri osrednje vzdolžne osi osnovne plošče, pri čemer je omenjena raazdalja usklajena z običajno perforacijo za vpenjanje predvidenih listov.

Obenem je na enem koncu osnovne plošče okoli osi, ki poteka pravokotno glede na omenjeno vzdolžno os in vsaj približno vzporedno z ravnino osnovne plošče zasukljivo uležiščen upravljalni vzvod, ki je na svoji proti osnovni plošči obrnjeni strani opremljen s klinom, ki je prirejen za vstopanje v vsakokrat razpoložljivo vrzel med omenjenima osrednjima območjema vpenjalnih stremen in s tem razpiranje le-teh v smeri vsaksebi, oz. po izbiri za izvlečenje iz omenjene vrzeli. Pri prednostni izvedbi mehanizma po izumu vsako od vpenjalnih stremen obsega po dva trna.The mechanism of the invention comprises a pair on a base plate about an axis parallel to the central longitudinal axis of a panel of rotatably fixed clamping straps, each of which is uniquely designed and consists of at least two spaced splines arranged on one side of said said spacing axes, and between the two trunks of the central region spaced apart, which, however, are located on each opposite side of said central longitudinal axis of the plate as the associated thorn. At the same time, at one end of the base plate about an axis extending orthogonal to said longitudinal axis and at least approximately parallel to the plane of the base plate, a pivotably mounted control lever equipped with a wedge adapted to enter the base plate facing the base thereof. the available gap between the two central areas of the clamping straps, thereby opening them in the direction of each other, or. optionally to extract from said gap. In a preferred embodiment of the mechanism of the invention, each of the clamping straps comprises two mandrels.

Vsakokratno vpenjalno streme je s svojima z vzdolžno osjo plošče vzporednima ležiščnima odsekoma zasukljivo uležiščeno v razpoložljivih ležiščih na osnovni plošči.Each clamping stirrup is rotatably supported by its two longitudinal axis of the plate in the available beds on the base plate.

Osrednja odseka vpenjalnih stremen sta prednostno med seboj vzporedna in hkrati tudi vzporedna z vzdolžno osjo osnovne plošče. Vsako od ležišč, ki je predvideno za zasukljivo pričvrstitev vsakokratnega vpenjalnega stremena na osnovno ploščo, je prednostno razporejeno na svojem koncu vpenjalne plošče, še zlasti prednostno pa vsako v svojem vogalnem območju osnovne plošče.The central sections of the clamping struts are preferably parallel to one another and at the same time parallel to the longitudinal axis of the base plate. Each of the bearings provided for rotatably securing the respective clamping strap to the base plate is preferably disposed at its end of the clamping plate, and particularly preferably each in its corner region of the base plate.

Upravljalni vzvod prednostno poleg klina obsega tudi prijemali, ki sta prirejeni za naleganje na osrednjih območjih vpenjalnih stremen. Pri tem je upravljalni vzvod s svojim vrtiščem zasukljivo pričvrščen v ležišču, kije razporejeno na enem koncu osnovne plošče.In addition to the wedge, the control lever also comprises grips that are adapted to be positioned in the central regions of the clamping straps. In this case, the control lever is pivotally mounted with its pivot in a bearing which is arranged at one end of the base plate.

Nadalje je upravljalni vzvod prednostno togo in enovito zasnovan ter poteka med vsakokrat sodelujočimi dvojicami trnov smiselno vsaj približno v smeri vzdolžne osi osnovne plošče. Razen tega omenjeni vzvod prednostno obsega dva vsaksebi štrleča konca, ki segata izven območja trnov, še zlasti tudi izven območja osnovne plošče.Further, the control lever is preferably rigidly and uniformly designed and runs between the cooperating pairs of thorns in each case, at least approximately in the direction of the longitudinal axis of the base plate. In addition, said lever preferably comprises two projecting ends extending beyond the area of the thorns, and in particular outside the area of the base plate.

Mahanizem po izumu sestoji iz osnovne plošče 1, na kateri sta zasukljivo in načeloma neodstranljivo pričvrščeni dve vsakokrat enovito zasnovani vpenjalni stremeni 2, 3, od katerih vsako obsega po dva med seboj razmaknjena vpenjalna trna 21, 22; 31, 32 in vsakokrat med slednjima razporejeno osrednje območje 23, 33, pri čemer sta omenjeni osrednji območji 23, 33 stremen 2, 3 prirejeni za sodelovanje z upravljalnim vzvodom 4, kije zasukljivo pričvrščen na enem koncu 11 omenjene plošče 1.The mechanism according to the invention consists of a base plate 1 on which two individually designed clamping straps 2, 3, each of which have two individually spaced clamping pins 21, 22, are each pivotally and indelibly fastened; 31, 32 and a central region 23, 33 respectively arranged between the two, said central regions 23, 33 of the stirrups 2, 3 being adapted to cooperate with a control lever 4 which is pivotably secured at one end 11 of said panel 1.

Osnovna plošča 1, katere osrednja vzdolžna os je na Sl. 1 označena kot os Χ-Χ, je v svojih vogalnih območjih 12', 12; 13', 13 opremljena z ustreznimi ležišči 120', 120; 130', 130, v katerih sta s pomočjo svojih z omenjeno osjo Χ-Χ vzporednih odsekov 210, 220; 310, 320 vsako zase na plošči 1 zasukljivo uležiščeni obe vpenjalni stremeni 2, 3.Base plate 1, the central longitudinal axis of which is in FIG. 1 is designated as the axis Χ-Χ, is in its corner regions 12 ', 12; 13 ', 13 fitted with suitable beds 120', 120; 130 ', 130, in which, by means of their parallel axis sections 210, 220, with said axis; 310, 320 each individually on plate 1 rotates both clamps 2, 3.

Na osnovni plošči 1 so nadalje predvidene pritrdilne luknje 15, s pomočjo katerih je plošča 1 pritrdljiva na vsakokratno podlago, npr. na neprikazano hrbtišče registratorja ali podobnega pripomočka za shranjevanje ali odlaganje listov, in sicer še zlasti npr. s pomočjo kovičenja.Mounting holes 15 are further provided on base plate 1, by means of which plate 1 is secured to the respective base, e.g. not shown on the back of the binder or similar accessory for storing or depositing sheets, in particular e.g. by riveting.

Kot rečeno, vpenjalni stremeni 2, 3 obsegata vsakokrat po dva vpenjalna trna 21, 22; 31, 32, pri čemer so omenjeni trni 21, 22; 31, 32 tako zasnovani, da sta po eni strani oba trnaAs mentioned, the clamping bores 2, 3 each comprise two clamping pins 21, 22; 31, 32, with said thorns 21, 22; 31, 32 so designed that, on the one hand, they are both spines

21, 22 oz. 31, 32 vsakokratnega vpenjalnega stremena 2, 3 razporejena na eni strani omenjene osrednje vzdolžne osi Χ-Χ mehanizma oz. plošče 1, obenem pa sta v vzdolžni smeri omenjene osi Χ-Χ med seboj razmaknjena za vnaprej določeno razdaljo, ki ustreza standardni razdalji med perforacijama na listu, predvidenem za vpenjanje v mehanizem. Tako se vsakokrat po en trn 21, 31 vsakega od vpenjalnih stremen 2, 3 nahaja na enem koncu 11' osnovne plošče 1, vsakokrat preostali trn 22, 32 pa na preostalem koncu 11 osnovne plošče 1. Pri tem sta med seboj sodelujoča trna 21,31 obeh stremen 2, 3 na enem koncu 1Γ plošče 1 prirejena za medsebojno soosno naleganje, prav tako pa sta za medsebojno soosno naleganje prirejena tudi preostala trna 22, 32 obeh stremen 2, 3 na preostalem koncu 11 osnovne plošče 1.21, 22 oz. 31, 32 of the respective clamping stirrup 2, 3 arranged on one side of said central longitudinal axis Χ-Χ of the mechanism or. plates 1, and at the same time, in the longitudinal direction of said axis, Χ-njena are spaced apart from each other by a predetermined distance corresponding to the standard distance between the perforations on the sheet intended for clamping into the mechanism. Thus, each thorn 21, 31 of each of the clamping straps 2, 3 are located at one end 11 'of the base plate 1, and each time the remaining thorn 22 and 32 are located at the remaining end 11 of the base plate 1. The two thorns 21 are cooperating with each other. 31 of both stirrups 2, 3 at one end 1Γ of the plate 1 are adapted for coaxial alignment, and the remaining spikes 22, 32 of both stirrups 2, 3 at the remaining end 11 of the base plate 1 are also adapted for coaxial alignment.

Vsako od omenjenih vpenjalnih stremen 2, 3 obsega z omenjeno osrednjo vzdolžno osjo Χ-Χ vsaj približno vzporedno osrednje območje 23, 33, ki je sicer izvedeno enovito z vsakokrat pripadajočima trnoma 21, 22; 31, 32, vendar se nahaja na drugi strani omenjene osrednje vzdolžne osi Χ-Χ kot pripadajoča trna 21, 22; 31, 32. To z drugimi besedami pomeni, da sta vpenjalni stremeni 2, 3 na plošči 1 s pomočjo svojih odsekov 210, 220; 310, 320 sicer zasukljivo uležiščeni, obenem pa sta razporejeni navzkrižno oz med seboj prekrižani, tako da osrednje območje 23 enega vpenjalnega stremena 2 sega preko osi ΧΧ proti trnoma 31, 32 preostalega vpenjalnega stremena 3, medtem ko osrednje območje 33 tega nazadnje omenjenega vpenjalnega stremena 3 sega osi Χ-Χ proti trnoma 21, 22 prvoomenjenega vpenjalnega stremena. Temu ustrezno ima premik osrednjega območja 23 vpenjalnega stremena 2 v smeri proti trnoma 31, 32 preostalega stremena 3 za posledico zasuk odsekov 210, 220 stremena 2 v ležiščih 120’, 120 osnovne plošče 1 in s tem premik trnov 21, 22 v smeri proti trnoma 31, 32 preostalega stremena 3. Povsem analogno ima tudi premik osrednjega območja 33 preostalega vpenjalnega stremena 3 v smeri proti trnoma 21, 22 prej omenjenega stremena 2 za posledico zasuk odsekov 310, 320 stremena 3 v ležiščih 130', 130 osnovne plošče 1 in s tem premik trnov 31, 32 v smeri proti trnoma 21, 12 preostalega stremena 2. Na ta način se vsakokrat sodelujoči dvojici trnov 21,31 oz. 22, 32 obeh vpenjalnih stremen 2, 3 dovede v medsebojno soosno naleganje, kar predstavlja zaprto stanje mehanizma po Sl. 2.Each of said clamping straps 2, 3 comprises, with said central longitudinal axis Χ-Χ, at least approximately a parallel central region 23, 33, which is otherwise made uniform with the respective strands 21, 22; 31, 32, but is located on the other side of said central longitudinal axis Χ-Χ as the corresponding mandrel 21, 22; 31, 32. In other words, this means that the clamping straps 2, 3 are in plate 1 by means of their sections 210, 220; 310, 320 are pivotally supported, but are arranged crosswise or crossed so that the central region 23 of one clamping strap 2 extends beyond the axis ΧΧ towards the tines 31, 32 of the remaining clamping strap 3, while the central region 33 of this last clamping strap 3 extends axis Χ-Χ toward the belts 21, 22 of the first-mentioned clamping strap. Accordingly, the displacement of the central region 23 of the clamping stirrup 2 in the direction of the webs 31, 32 of the remaining webbing 3 results in the rotation of sections 210, 220 of the webbing 2 in the beds 120 ', 120 of the base plate 1 and thereby the movement of the webs 21, 22 in the direction of the webs 31, 32 of the remaining stirrup 3. In a completely analogous fashion, the displacement of the central region 33 of the remaining clamping stirrup 3 in the direction of the straps 21, 22 of the previously mentioned stirrup 2 results in a rotation of sections 310, 320 of the stirrup 3 in the beds 130 ', 130 of the base plate 1 and s. in this way, the movement of the mandrels 31, 32 in the direction of the mandrels 21, 12 of the remaining stirrup 2. In this way, the cooperating pair of mandrels 21.31, respectively. 22, 32 bring the two clamping straps 2, 3 into a coaxial alignment, which represents the closed state of the mechanism of FIG. 2.

Po drugi strani pa premik osrednjih območij 23, 33 vpenjalnih stremen 2, 3 v nasprotni smeri, torej vsaksebi, privede do razpiranja trnov 21,31 oz. 22, 32 oz odprtja mehanizma (Sl. 1 in 3).On the other hand, the displacement of the central regions 23, 33 of the clamping stirrups 2, 3 in the opposite direction, that is, in each other, leads to the breaking of the thorns 21,31 or. 22, 32 oz of mechanism opening (Figs. 1 and 3).

Kot je bilo uvodoma omenjeno, je na enem koncu 11 osnovne plošče 1 v ustreznem ležišču 14 na plošči 1 s svojim vrtiščem 40 zasukljivo uležiščen upravljalni vzvod 4, in sicer na tak način, daje zasukljiv okoli osi, ki je pravokotna glede na omenjeno vzdolžno os Χ-Χ in vsaj približno vzporedna z ravnino osnovne plošče 1. Temu ustrezno je omenjeni vzvod 4 zasukljiv v ravnini, ki poteka vsaj približno pravokotno glede na ravnino osnovne plošče 1 in vsaj približno vzporedno z osrednjo os Χ-Χ oz. s slednjo prednostno kar sovpada.As mentioned above, at one end 11 of the base plate 1 in the corresponding bearing 14 on the plate 1, with its pivot 40, the pivoting control lever 4 is rotated in such a way that it rotates about an axis perpendicular to said longitudinal axis Χ-Χ and at least approximately parallel to the plane of the base plate 1. Accordingly, said lever 4 is rotatable in a plane extending at least approximately orthogonal to the plane of the base plate 1 and at least approximately parallel to the central axis Χ-Χ or. with the latter preferably coinciding.

Upravljalni vzvod 4 je razmeroma togo zasnovan in poteka v območju med omenjenimi trni 21, 31; 22, 32 vpenjalnih stremen, obenem pa s svojima vsaksebi štrlečima koncema 41, 42 prednostno sega izven območja omenjenih trnov 21, 32; 22, 32 oz. preko obeh koncev 1Γ, 11 osnovne plošče 1. Razen tega je omenjeni vzvod 4 na svoji proti osnovni plošči 1 obrnjeni spodnji strani 43 opremljen s klinom 44, ki je prirejen za sodelovanje z osrednjima območjema 23, 33 vpenjalnih stremen 2, 3, in sicer na tak način, da omenjeni klin 44 po izbiri lahko vstopi med omenjeni osrednji območji 23, 33 in ju razpre. Poleg omenjenega klina 44 sta na vzvodu 4 prednostno predvideni prijemali 45, 44, ki sta prurejeni za naleganje na osrednjih območjih 23, 33 vpenjalnih stremen 2, 3, kadar je omenjeni klin 44 vzvoda 4 izvlečen iz vrzeli med vmesnima območjema 23, 33 vpenjalnih stremen 2, 3.The control lever 4 is relatively rigidly designed and extends in the region between said spikes 21, 31; 22, 32 of the clamping straps, and preferably with their projecting ends 41, 42 preferably extending beyond the area of said spikes 21, 32; 22, 32 oz. through both ends 1Γ, 11 of base plate 1. In addition, said lever 4 is provided with a wedge 44 on its opposite base plate 1 facing lower 43, which is adapted to cooperate with the central regions 23, 33 of the clamping straps 2, 3, namely in such a way that said wedge 44 can optionally enter and open between said central regions 23, 33. In addition to said wedge 44, the levers 4 are preferably provided with grips 45, 44 provided for mounting in the central regions 23, 33 of the clamping straps 2, 3 when said lever 44 of the lever 4 is pulled out of the gap between the intermediate regions 23, 33 of the clamping straps. 2, 3.

Ko je mehanizem po izumu v območju lukenj 15 pritrjen pritrjen na hrbtišče registratorja, s pritiskom na tisti konec 42 upravljalnega vzvoda 4, ki se nahaja v bližini vrtišča 40 in izvleženjem klina 44 iz vrzeli med osrednjima območjema 23, 33 vpenjalnih stremen 2, 3, kar ima za posledico, da sta vsakokrat med seboj sodelujoča trna 21, 31; 22, 32 razprta (Sl. 1). V takem položaju lahko npr. na trna 31, 32 namestimo ustrezno perforiran list ali sveženj listov. S pritiskom na preostali konec 41 vzvoda 4 dosežemo, da klin 44 vzvoda 4 vstopi med osrednji območji 23, 33 vpenjalnih stremen 2, 3, ki se premakneta vsaksebi, kar privede do soosnega med seboj soosnega naleganja ,ed seboj vsakokrat sodelujočih trnov 21, 31; 22, 32 obeh vpenjalnih stremen 2, 3 in torej do zaprtja mehanizma. Odtlej so v mehanizmu vpeti listi varovani proti izpadanju. Pri tem je omenjeni klin 44 prednostno tako oblikovan, da med vtiskanjem klina 44 med osrednji območji 23, 33 stremen 2, 3 že po vtisnjenju npr. tretjine dolžine klina 44 vsakokrat sodelujoča trna 21, 31; 22, 32 že dospeta v medsebojni dotik, tako da še nadaljnje prodiranje klina 44 v dobljeno vrzel med osrednjima območjema 23, 33 stremen 2, 3 zahvaljujoč elastični deformaciji trnov 21, 31; 22, 32 povzroči še dodatno povečanje pritisk med vsakokrat sodelujočima trnoma 21, 31; 22, 32, kar preprečuje odprtje mehanizma oz. razprtje trnov 21, 31; 22, 32 tudi pri vsakovrstnih regularnih obremenitvenih stanjih povsem napolnjenega registratorja.When the mechanism according to the invention is fixed in the hole region 15 to the back of the binder by pressing that end 42 of the control lever 4 located near the pivot 40 and removing the wedge 44 from the gap between the central regions 23, 33 of the clamping straps 2, 3, resulting in the fact that the twigs 21, 31 interact with each other; 22, 32 scattered (Fig. 1). In such a situation, e.g. a properly perforated sheet or bundle of sheets is fitted to the mandrels 31, 32. By pushing the remaining end 41 of the lever 4, the lever 44 of the lever 4 enters between the central regions 23, 33 of the clamping stirrups 2, 3, which move to each other, resulting in a coaxial alignment with each other, each of the cooperating mandrels 21, 31 ; 22, 32 of the two clamping straps 2, 3 and thus until the mechanism is closed. Since then, the clamped leaves are secured against falling out. Preferably, said wedge 44 is formed in such a way that during the insertion of the wedge 44 between the central regions 23, 33 of the stirrups 2, 3, already after insertion, e.g. thirds of the length of the wedge 44 each participating mandrel 21, 31; 22, 32 are already in contact with each other so that further penetration of the wedge 44 into the resulting gap between the central regions 23, 33 of the struts 2, 3 due to the elastic deformation of the mandrels 21, 31; 22, 32 further exacerbates the pressure between the co-operating bands 21, 31; 22, 32, which prevents the mechanism or thoracic dissection 21, 31; 22, 32 even with all kinds of regular loading conditions of a fully filled binder.

Ponovno razprtje trnov 21, 31; 22, 32 in s tem odprtje mehanizma dosežemo s pritiskom na nasprotni konec 42 vzvoda 4. Pri tem je očitno, da obravnavani mehanizem omogoča listanje v odprtem položaju, saj vzvod 4 celo v takem stanju mehanizma ne ovira premeščanja listov s trnov 21, 22 enega stremena 2 na trna 31, 32 preostalega stremena 3 ali obratno. Listanje je v tem pogledu popolnoma neovirano celo pri povsem napolnjenem registratorju, in sicer ne glede na to, ali se ta nahaja v odprtem ali zaprtem stanju. Za razliko od klasičnih mehanizmov, pri katerih sta dva trna na osnovni plošči nepremakljivo pritrjena, in sta zgolj preostala dva trna skupaj s pripadajočim vpenjalnim sklopom na plošči za določen kot zasukljiva in s tem premakljiva, sta pri mehanizmu po izumu na plošči 1 zasukljivi obe stremeni 2, 3 z obema dvojicama trnov 21, 22; 31, 32. To seveda pomeni, da je razdalja med vsakokrat sodelujočima trnoma 21, 31; 22, 32 v razprtem stanju lahko znatno večja kot pri klasičnih mehanizmih, kar ima za posledico, da je v mehanizem po izumu brez težav mogoče vstaviti debelejši sveženj listov oz. tovrsten sveženj potem iz registratorja tudi naenkrat odstraniti.Re-opening of spines 21, 31; 22, 32, and thus the opening of the mechanism is achieved by pressing the opposite end 42 of the lever 4. In this case, it is obvious that the mechanism in question allows leafing in the open position, since the lever 4 does not even interfere with the movement of leaves from the mandrels 21, 22 even in such a state of the mechanism. stirrups 2 on spikes 31, 32 of remaining stirrups 3, or vice versa. Scrolling is completely unobstructed in this respect, even with a fully-filled binder, whether open or closed. Unlike conventional mechanisms in which two mandrels are fixed to the base plate and only the remaining two mandrels together with the associated clamping assembly on the plate are defined as rotatable and thus movable, the two mechanisms are rotatable in the mechanism according to the invention on plate 1. 2, 3 with both twin thorns 21, 22; 31, 32. This, of course, implies that the distance between each of the participating thorns is 21, 31; 22, 32 in the open state can be substantially larger than in conventional mechanisms, which results in the fact that a thicker bundle of leaves or leaves can easily be inserted into the mechanism according to the invention. this bundle should then be removed from the binder at once.

V primerjavi s klasičnimi mehanizmi je pri mehanizmu po izumu zaradi ugodnejšega obremenitvenega stanja in odsotnosti nekaterih tam nepogrešljivih sestavnih delov kot npr. vzmeti, osnovna plošča 1 lahko znatno poenostavljena. V prikazanem primeru izvedbe je plošča 1 v bistvu podkvasto zasnovana, kar pomeni, daje njena širina v smeri pravokotno glede na os Χ-Χ v osrednjem območju 11 znatno manjša kot na konceh IT, 11. S tem je plošča 1 mehanizma po izumu v primerjavi s ploščami pri klasičnih mehanizmih lahko znatno lažja in torej omogoča doseganje znatnih prihrankov pri materialu.Compared to conventional mechanisms, the mechanism according to the invention is due to a more favorable loading condition and the absence of some indispensable components there, such as e.g. springs, base plate 1 can be greatly simplified. In the embodiment shown, panel 1 is substantially subquadratically designed, meaning that its width in the direction perpendicular to the axis Χ-Χ in the central region 11 is significantly smaller than at the ends of the IT, 11. Thus, panel 1 of the mechanism according to the invention is in comparison using panels with classical mechanisms can be significantly easier and therefore achieve significant material savings.
