Vpenjalni mehanizem registratorjaClamping mechanism of the binder
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.
Izhodišče izuma predstavlja znan mehanizem, ki obsega osnovno ploščo z dvojico na sebi togo pričvrščenih trnov ter vpenjalni sklop, obsegajoč dvojico med seboj preko vzmetno podprtega vmesnega odseka togo povezanih zavihtljivih in proti prej omenjenima trnoma zahvaljujoč premiku ustrezne upravljalne ročice pritisljivih trnov. Pri tem je cilj pričujočega izuma po eni strani zagotoviti še večji kot razpiranja med premakljivima in nepremakljivima trnoma, obenem pa tudi, da se bo ročica tudi v razprtem položaju omenjenih dvojic trnov nahajala v takem položaju, da bo uporabniku omogočeno listanje v mehanizmu vpetih listov, pri čemer pa naj bi bilo brezhibno delovanje mehanizma zagotovljeno s kar najmanjšimi možnimi posegi v obstoječo konstrukcijsko zasnovo tovrstnega mehanizma in po možnosti z uporabo že obstoječe osnovne plošče in vpenjalnega sklopa vsaj kot polizdelkov za izdelavo končnega izdelka. Ob uspešni razrešitvi omenjenega problema bi bil namreč izum lahko realiziran hitro s kar najmanjšimi finančnimi vlaganji v razvoj in izdelavo preoblikovalnih orodij in drugih izdelovalnih naprav.The starting point of the invention is a known mechanism comprising a base plate with two rigidly fastened mandrels and a clamping assembly, comprising a pair of interconnecting rigidly connected pivoting and against the aforementioned mandrels by means of a spring-supported intermediate section due to the movement of the corresponding control lever of the pressing mandrels. The object of the present invention is to provide, on the one hand, even greater than the openings between the movable and non-movable mandrels, and at the same time that the lever will also be in the open position of said pair of mandrels in such a position as to allow the user to scroll in the mechanism of the clamped leaves, however, the flawless operation of the mechanism should be ensured by the least possible interference with the existing structural design of such mechanism and, if possible, by using an already existing base plate and clamping assembly at least as semi-finished products for the manufacture of the finished product. If this problem is successfully solved, the invention could be realized quickly with minimal financial investment in the development and manufacture of transformation tools and other manufacturing equipment.
Iz GB 815,108 je znan vpenjalni mehanizem, pri katerem sta na osnovni plošči vpeta dvojica med seboj razmaknjenih nepremakljivih trnov, ki sta prirejena za sodelovanje z dvojico premakljivih trnov, ki sta med seboj povezana preko stremena in skupaj s slednjim tvorita vpenjalni sklop, ki je v ustreznih ležiščih zasukljivo oz. z možnostjo nagibanja pričvrščen na osnovni plošči. Nadalje je na osnovni plošči predviden iz srednje izsekan in v bistvu pravokotno odkrivljen osrednji nosilec, na katerem je zasukljivo pričvrščen nihajni vzvod upravljalne ročice registratorja, kije zasukljivo vpeta na nadaljnjem nosilcu na osnovni plošči. Upravljalna ročica je torej po eni strani na osnovno ploščo zasukljivo pričvrščena s pomočjo nazadnje omenjenega nosilca in pri tem podprta z vzmetjo, ki ročico odriva v smeri vstran od osnovne plošče, po drugi strani pa je členkasto povezana z omenjenim na osrednjem nosilcu zasukljivo pričvrščenem nihajnim vzvodom, ki je opremljen s pritisnim elementom, ki je oprt na ekscentrično zasnovano osrednje območje stremena vpenjalnega sklopa. Nadalje je v osrednjem območju nihajnega vzvoda na voljo zajeda, v katero uprijema aretimi element, ki je predviden za držanje nihajnega vzvoda v ustreznem položaju, kadar je ročica mehanizma proti sili omenjene vzmeti pritisnjena v smeri proti osnovni plošči in je mehanizem zaprt, tako da je vsak od obeh premakljivih trnov pritisnjen proti vsakokrat pripadajočemu nepremakljivemu trnu. Tovrsten mehanizem terja vgradnjo številnih delov in je zato razmeroma zapleten in nezanesljiv.GB 815,108 discloses a clamping mechanism in which two fixed spaced fixed splines are attached to the base plate, adapted to cooperate with two movable spikes that are connected to each other via a strap and together with the latter form a clamping assembly which is in suitable beds rotatable respectively. tiltable fixed to base. Furthermore, a central carrier is provided on the base plate with a substantially incised and substantially rectangularly discovered central carrier, on which a pivoting lever of the control lever of the binder is fixed, which is rotatably mounted on a further carrier on the base plate. The control lever is therefore, on one side, pivotally fastened to the base plate by means of the aforementioned bracket, supported by a spring which pulls the lever away from the base plate and, on the other hand, is articulated to the pivotally pivoted lever mentioned on the central bracket. , which is provided with a pressure member which is supported by an eccentrically designed central region of the clamp assembly. Further, a pivot is provided in the pivot pivot region in which the arresting element is provided to hold the pivot lever in a suitable position when the lever mechanism of said spring is pressed toward the base plate and the mechanism is closed so that each of the two movable mandrels pressed against the respective motionless mandrel. Such a mechanism requires the installation of many parts and is therefore relatively complex and unreliable.
Eden tačas najbolj znanih in uporabljanih vpenjalnih mehanizmov 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, ki je uležiščena na nosilcu, ki je predviden približno v osrednjem območju osnovne plošče in predstavlja del slednje oz. je s slednjo togo povezan.One of the most well-known and used clamping mechanisms of the binder is described in WO 20/04082961 respectively. 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 handle, 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 se 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. Osnovna plošča je navzlic razmeroma majhni debelini izhodiščnega materiala dovolj toga in tudi sam vpenjalni sklop je perfektno zasnovan in deluje optimalno, obenem pa je tudi proces izdelave in tudi sestavljanja omenjenih sestavnih delov optimalen, v celoti avtomatiziran in omogoča cenovno sprejemljivo izkoriščanje rešitve po EP 1 606 122.This mechanism is undoubtedly very reliable and efficient, as it enables fast and reliable clamping of a relatively large number of leaves. The base plate, despite the relatively small thickness of the starting material, is sufficiently rigid and the clamping assembly itself is perfectly designed and operates optimally, while the process of manufacturing and assembling said components is optimal, fully automated, and enables affordable utilization of the EP 1 606 solution 122.
Problem nastopi, kadar uporabnikove potrebe narekujejo pogosto listanje in premeščanje vpetih listov ali npr. preurejanje vsebine registratorja, še zlasti npr. zamenjavo vrstnega reda 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 izključno pod pogojem, da je 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. V tem kontekstu bi bilo pogosto zelo ugodno, če bi bil kot razprtja med vsakokratnim premakljivim in nepremakljivim trnom karseda velik, ker bi bilo v takem primeru možno premeščati tudi debelejše svežnje listov.The problem arises when the user's needs are dictated by frequent leafing and moving of pinned sheets or e.g. rearranging the contents of the binder, especially e.g. swap order of pinned leaves or the like. In such a case, the scrolling i.e. the movement of leaves from the area of fixed spines to the region of movable spines or vice versa, otherwise possible, but only if 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 this context, it would often be very advantageous if the opening angle between each movable and stationary cane was as large as possible, since in such a case it would also be possible to move thicker bundles of leaves.
Nadalje je v EP 1 226 987 predlagan v osnovi sicer analogno zasnovan 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 tudi v tem primeru 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 odrinjen iz ravnine osnovne plošče s pomočjo vzmeti, kije vgrajena na osnovni plošči pod omenjenem osrednjim območjem vmesnega odseka.Furthermore, EP 1 226 987 proposes a fundamentally analogous mechanism, in which case again a base plate with rigidly fixed watertight webs and a central carrier on which the pivot of the lever is located are again available. In this case, the movable spikes are also pivotally supported on the base plate and interconnected by an intermediate section whose central area is pressed in the direction towards the plane of the base plate by means of the eccentrically spaced roller element on the lever, while at the same time said intermediate section being detached from the plane of the base plate. plates 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 odprtem stanju mehanizma. S tem namreč tudi pri zahtevnejšem razvrščanju odpade potreba po zapiranju in odpiranju 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. Tako 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 clamped sheet recorder, even in the open state of the mechanism. This means that even with more complex sorting, the need for closing and opening the mechanism is eliminated. 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. Thus, by relatively simple modification of the base plate, namely, by performing 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 trna 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. 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.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 opened for a certain distance with a correspondingly reduced stroke of the lever, the transmission ratio between the force on the lever and the force by which the movable mandrel 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. 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.
Še nadalje je tudi 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 trnov. Premakljiva trna sta tudi v tem primeru zavihtljivo uležiščena na osnovni plošči in med seboj povezana preko ekscentrično razporejenega vmesnega odseka, 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 velikimi napori in vlaganji, s čimer uvodoma zastavljeni problem v tem pogledu torej ostaja nerešen.Further, WO 2005/047015 also describes a binder mechanism, which also comprises a base plate, a pair of rigidly connected rigid joints, and a twin by means of a suitable movable mandrel handle. In this case, the movable spikes are also pivotally supported on the base plate and interconnected via an eccentrically spaced 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 great effort and investment, which, therefore, remains an unsolved problem in this regard.

EP 1 606 122 and is extensively manufactured by the applicant and for that purpose possesses all the necessary transformation tools and other devices to allow the large-scale production to proceed smoothly. Such a control mechanism of the binder generally consists of a base plate and a clamping assembly, which is pivotally secured on said panel and operated by means of a control lever which is also pivotally secured on said panel. In this case, on the base plate near one longitudinal side, there are provided two mutually spaced apart, approximately perpendicular to the plane of the base plate of the fixed and fixed rigidly connected pins. A pivot bracket is available in the central area of the base plate, and in the area of the aforementioned side of the opposite longitudinal side there are provided beds to support the clamping assembly on the plate. This clamping assembly comprises a pair for cooperating with the aforementioned mandrels in terms of the possibility of interlocking in the coaxial alignment of the adjustable movable mandrels, between which there is an eccentrically designed intermediate part supported in the direction of said support, supported by and away from the base plate. a spring, between said section and said movable mandrels, are provided bearing regions by which the assembly is pivotally mounted in the bearings of the base plate. Furthermore, a control lever extending at least approximately in the longitudinal direction is rotated further in the pivot on said base plate carrier. of the base plate and between one fixed cane and the associated moving cane extends beyond the area of the base plate. The lever is adapted to cooperate with said central section of the clamping assembly, which is thereby pressed on the one side by a spring in the direction away from the base plate and, on the other hand, thanks to the lever optionally pressed in the direction towards the base plate.

Omenjeni nosilec 13 ročice 3 je razporejen približno v osrednjem območju osnovne plošče 1 in postavljen v bistvu pravokotno glede na ravnino plošče 1. Omenjeni nosilec 13 je tako kot sama osnovna plošča 1 zasnovan karseda togo, in sicer z namenom, da bi bilo uležiščenje upravljalne ročice 3 in s tem upravljanje vpenjalnega sklopa 2 lahko karseda natančno.Said carrier 13 of the lever 3 is arranged approximately in the central region of the base plate 1 and is positioned substantially orthogonal to the plane of the plate 1. Said carrier 13, like the base plate 1 itself, is designed as rigidly as possible to support the control lever 3, and thus control of clamping assembly 2 can be as precise as possible.
Še nadalje je na osnovni plošči 1 v območju med omenjenim nosilcem 13 in omenjenim vzdolžnim robom 18 v ustreznem izrezu 10' v omenjeni plošči 1 vstavljena vzmet 10, kije vgrajena in tudi izvedena na povsem enak način kot v primeru mehanizma iz stanja tehnike (WO 20/04082961 oz. EP 1 606 122). Z omenjeno vzmetjo 10 je na plošči 1 podprt vmesni odsek 25 vpenjalnega sklopa 2. Vzmet 10, ki načeloma sestoji iz drugačnega materiala kot je material same osnovne plošče 1, je v omenjenem izrezu 10' v plošči 1 konzolno vpeta in je na voljo kot upogibna listnata vzmet.Furthermore, a spring 10 is inserted in the base plate 1 in the area between said carrier 13 and said longitudinal edge 18 in the corresponding recess 10 'in said plate 1, which is mounted and also executed in exactly the same manner as in the case of the prior art mechanism (WO 20 / 04082961 or EP 1 606 122). With said spring 10, the intermediate section 25 of the clamping assembly 2 is supported in plate 1. The spring 10, which in principle consists of a material other than the material of the base plate 1 itself, is cantilevered in said recess 10 'in plate 1 and is available as a bending leaf spring.

Vpenjalni sklop 2, ki sicer v osnovi lahko popolnoma ustreza znanemu sklopu 2 iz stanja tehnike (WO 20/04082961 oz. EP 1 606 122), je za potrebe pričujočega izuma modificiran na tak način, da je v območju osrednjega odseka 25 opremljen z vodilom 26, ki je prirejeno tako za sodelovanje z upravljalno ročico 3 kot tudi z vmesnim segmentom 4, ki je vstavljen med upravljalno ročico 3 in omenjenim vodilom 26 na osrednjem odseku 2 vpenjalnega sklopa 2. Omenjeno vodilo 26 v prikazanem primeru sestoji iz polimernega materiala in je bodisi v ustreznem orodju nabrizgano neposredno na osrednji odsek 25 ali pa je izdelano posebej in zatem pritrjeno na omenjen osrednji odsek 25.The clamping assembly 2, which may basically correspond completely to the known assembly 2 of the prior art (WO 20/04082961 or EP 1 606 122), is modified for the purposes of the present invention in such a way that it is provided with a guide in the area of the central section 25 26, which is adapted to cooperate with the control lever 3 as well as with the intermediate segment 4 inserted between the control lever 3 and said guide 26 in the central section 2 of the clamping assembly 2. Said guide 26 in this example consists of a polymeric material and is either injected directly into the center section 25 in a suitable tool, or specially designed and subsequently attached to said center section 25.
Vmesni segment 4 je v prikazanem primeru zasnovan kot podolgovato, na svojih konceh 41, 42 blago zaokroženo kompaktno telo dolžine L in debeline B, kije z možnostjo zasuka za vsaj približno 90° oblikosklepno vstavljeno med ročico 3 in omenjenim vodilom vpenjalnega sklopa 2.In this example, intermediate segment 4 is designed as an elongated, at its ends 41, 42, a slightly rounded compact body of length L and thickness B, which is rotatably inserted between the lever 3 and said guide of the clamping assembly 2 by at least about 90 °.
Z namenom vodenja omenjenega segmenta 4 so na ročici 3 - gledano v vzdolžni smeri slednje - na eni strani 351 glede na vrtišče 31 predvideni nased 32, kije prirejen za prejem pripadajočega konca 41 segmenta 4, nastavek 33, kije prirejen za premikanje segmenta 4 med zasukom ročice 3 okoli njenega vrtišča 31 na nosilcu 13, in naslon 34, s katerim je ročica 3 oprta na pripadajočo površino 263 vodila 26 na osrednjem odseku 25 vpenjalnega sklopa 2. Na glede na vrtišče 31 nasprotni strani 352 ročice 3 je predviden nased 36, s katerim je ročica 3 po izbiri oz. alternativno prav tako lahko oprta na vodilu 26. Prav tako z namenom vodenja omenjenega segmenta 4 je tudi omenjeno vodilo 26 vmesnega odseka 25 vpenjalnega sklopa 2 opremljeno z nasedom 261, ki je prirejen za prejem pripadajočega zaokroženega konca 42 segmenta 4, nadalje z ustrezno naležno površino 262, ki je prirejena za sodelovanje z naslonom 34 ročice 3, in še nadalje tudi z naležno površino 263, kije prirejena za sodelovanje z nasedom 36 ročice 3. Omenjeni segment 4 je torej v osnovi oblikosklepno vstavljen med ročico 3 in omenjenim vodilom 26, tako da je po eni strani s svojim koncem 41 oprt na ročico 3 v območju njenega naseda 32 in po drugi strani s svojim drugim koncem 42 na vodilo 26 v območju njegovega naseda 261.In order to guide said segment 4, on the lever 3 - viewed in the longitudinal direction of the latter - on one side 351 with respect to the pivot 31, there is provided a seat 32 adapted to receive the corresponding end 41 of the segment 4, attachment 33 adapted to move the segment 4 during rotation. a lever 3 around its pivot 31 on the carrier 13, and a backrest 34, by which the lever 3 is supported on the corresponding surface 263 of the guide 26 in the central section 25 of the clamping assembly 2. With respect to the pivot 31 opposite side 352 of the lever 3, a seat 36 is provided, s having a lever 3 of choice or. alternatively, it can also be supported on the guide 26. Likewise, for the purpose of guiding said segment 4, said guide 26 of the intermediate section 25 of the clamping assembly 2 is provided with a tie 261 adapted to receive the corresponding rounded end 42 of the segment 4, further with a corresponding contact surface. 262, adapted to engage with the arm 34 of the arm 3, and further to the contact surface 263 adapted to engage with the arm 36 of the arm 3. Said segment 4 is thus essentially closed in a form between the arm 3 and said guide 26, thus that, on the one hand, with its end 41, it rests on a lever 3 in the area of its seat 32, and on the other, with its other end 42, on a guide 26 in the area of its seat 261.
Kot je bilo omenjeno, je glede na ležišči 19', 19 vpetja vpenjalnega sklopa 2 ekscentrično vpet vmesni odsek 25 vpenjalnega sklopa 2 podprt z vzmetjo 10 in s tem načeloma pritiskan v smeri vstran od osnovne plošče 1, pri čemer so trni 11, 12; 21, 22 razprti. Kadar je mehanizem odprt in trni 11, 12; 21, 22 razprti, je ročica 3 okoli vrtišča 31 zasukana vstran od osnovne plošče 1, nased 36 ročice 3 pa je oprt na naležni površini 263 vodila 26 na osrednjem odseku 25 vpenjalnega sklopa 2.As mentioned, with respect to the bushings 19 ', 19 of the clamping assembly clamp 2, the eccentrically clamped intermediate section 25 of the clamping assembly 2 is supported by a spring 10 and thus is generally pressed in the direction away from the base plate 1, the spikes 11, 12; 21, 22 dispersed. When the mechanism is open and the tines 11, 12; 21, 22 open, the lever 3 around the pivot 31 is rotated away from the base plate 1, and the lever 36 of the lever 3 is supported on the bearing surface 263 of the guide 26 in the central section 25 of the clamping assembly 2.
Ob pritisku na ročico 3 v smeri proti osnovni plošči 1 se omenjeno naleganje naseda 36 ročice 3 na naležni površini 263 vodila 26 odpravi, namesto tega pa ročica 3 s svojim naslonom 34 naleže na površino 262 vodila 26 in pri tem pritiska vodilo 26 skupaj z osrednjim odsekom 25 vpenjalnega sklopa 2 v smeri proti osnovni plošči 1 in torej proti sili vzmeti 10. Med premikanjem oz. zasukom ročice 3 okoli vrtišča 31 omenjeni nastavek 33 ročice 3 pred seboj potiska pripadajoči konec 41 segmenta 4, kije s svojim preostalim koncem 42 oprt na nasedu 262 vodila 26, tako da se tudi segment 4 med sukanjem ročice 3 premika in obenem tudi sam suče. Zaradi podolgovate zasnove segmenta 26 dolžine L in širine B se med celotnim zasukom ročice 3 omenjeni segment 4 zasuče in prestavi iz položaja vzporedno z ravnino osnovne plošče 1 v položaj vsaj približno pravokotno glede na omenjeno ravnino osnovne plošče 1, pri čemer se osrednji odsek 25 vpenjalnega sklopa 2 premakne v smeri proti osnovni plošči 1 in torej proti sili vzmeti 10 za določeno razdaljo, ki načeloma ustreza razliki med dolžino L in širino B segmenta 26, torej za vrednost (L - B). Če se segment 4 med omenjenim sukanjem zasuče za malenkost več kot 90°, se potem v takem stanju tudi zaskoči in s tem prepreči zasuk ročice 3 v nasprotno smer, do česar bi sicer prišlo zaradi delovanja sile vzmeti 10 na vmesni odsek 25 vpenjalnega sklopa 2. V takem stanju (Sl. 4 in 6) je mehanizem zaprt, pri čemer sta premakljiva trna 21, 22 pritisnjena proti nepremakljivima trnoma 11, 12, ročica 3 pa je držana v bližini osnovne plošče 1. Stopnja zaskočenosti segmenta 4 v omenjenem položaju in s tem sila zadrževanja ročice 3 v omenjenem zaprtem položaju mehanizma je odvisna od tega, za koliko kot zasuka segmenta 4 presega kot 90°°.When the lever 3 is pressed towards the base plate 1, the said bearing arrangement 36 of the lever 3 on the bearing surface 263 of guide 26 is removed, and instead the lever 3 with its support 34 rests on the surface 262 of guide 26, while pushing guide 26 together with the central section 25 of the clamping assembly 2 in the direction of the base plate 1 and therefore against the force of the spring 10. While moving or. rotating the crank 3 around the pivot 31, said nozzle 33 of the crank 3 pushes before it the corresponding end 41 of the segment 4, which with its remaining end 42 rests on the seat 262 of the guide 26, so that the segment 4 also moves during the rotation of the crank 3 and simultaneously rotates. Due to the elongated design of segment 26 of length L and width B, during the entire rotation of the lever 3, said segment 4 rotates and moves from a position parallel to the plane of the base plate 1 to a position at least approximately orthogonal to said plane of the base plate 1, wherein the central section 25 of the clamp of assembly 2 moves in the direction of base plate 1 and therefore against the force of spring 10 for a certain distance, which in principle corresponds to the difference between length L and width B of segment 26, that is, for value (L - B). If the segment 4 rotates by a little more than 90 ° during said rotation, then it will also snap in such a state, thereby preventing the arm 3 from rotating in the opposite direction, which would otherwise be due to the force of the spring 10 on the intermediate section 25 of the clamping assembly 2 In such a state (Figs. 4 and 6), the mechanism is closed, the movable mandrels 21, 22 being pressed against the non-movable mandrels 11, 12, and the lever 3 being held near the base plate 1. The engagement level of segment 4 in said position and thus, the holding force of the lever 3 in said closed position of the mechanism depends on how much the angle of rotation of segment 4 exceeds that of 90 °°.
Šele pritisk na ročico 3 v smeri vstran od osnovne plošči 1 povzroči tolikšen zasuk ročice 3, daje zahvaljujoč pritisku vzmeti 10 možen zasuk segmenta 4 v izhodiščni položaj (Sl. 1 do 3 in 5).Only the pressure on the lever 3 in the direction away from the base plate 1 causes the lever 3 to rotate so much that, thanks to the spring pressure, 10 it is possible to rotate the segment 4 to its starting position (Figs. 1 to 3 and 5).
