Description
Protipovratna, hoteno popustljiva naprava za sprejem in držanje napete ovalnočlenkaste verigeNon-return, indulgently indulgent device for receiving and holding a taut oval chain
Področje tehnike, kije generiralo predmetni izum, so tim. snežne verige, torej iz verig in spremljajočih delov narejeni verižnomrežasti sklopi, ki - nameščeni na kolesno gumo motornega vozila in primerno napeti - služijo kot pomožne, dodatne naprave za preprečevanje zdrsov na vozni osnovi, za sodelovanje s katero kolesna guma kot taka ni tehnično optimalna. IntCl.: B 60 C 27/10.The field of technology that generated the present invention is team. snow chains, that is, chains and related components made of chain-link assemblies, which - mounted on the wheel of a motor vehicle tire and properly tensioned - serve as auxiliary, additional anti-slip devices on a rolling stock for cooperation with which the wheel tire as such is not technically optimal. IntCl .: B 60 C 27/10.
Izum se nanaša na protipovratno, hoteno popustljivo napravo za sprejem in držanje ovalnočlenkaste verige, zlasti za - pri nameščanju - vključitev prostega, zategovalnega konca bočne, sklepne verige v verižno stičišče, ki ga tvorijo drugi konec bočne, sklepne verige in prečno-diagonalni verigi snežne verige za motorna vozila, obsegajočo sprejemno-vodilni del, v katerem je urejen prehod za sprejem in vodenje zategovalnega konca bočne, sklepne verige snežne verige, in zapahnilni del, ki se ga da ročno odpahniti.The invention relates to a non-returnable, willingly indulgent device for receiving and holding an oval chain, in particular for integrating the free, tightening end of the lateral, articulated chain into a chain junction formed by the other end of the lateral, articulated chain and cross-diagonal snow chain. a motor vehicle chain comprising a receiving-guide portion, which comprises a passage for receiving and guiding the tightening end of the lateral, chain-linking snow chain, and a manually-releasable locking portion.
Naprava, ki je predmet izuma, je pri snežni verigi pripomoček, s pomočjo katerega se v sklepno verižno stičišče, v katerem se na kolesno gumo motornega vozila nameščena snežna veriga zategne/napne in ki se v navedenem stanju nahaja v območju vznožja/boka kolesne gume na odmiku od platišča kolesa, vpelje in fiksira zategovalni konec bočne, sklepne verige. Gre za stičišče, v katerem so pri snežni verigi trajno priključeni en konec bočne, sklepne verige in dve prečno-diagonalni verigi.The device of the invention is, in the case of a snow chain, a device by means of which a snow chain is fastened / tensioned in the joint chain junction in which a snow chain is mounted on the wheel of a motor vehicle and which is in said condition in the region of the foot / side of the tire. at the distance from the wheel rim, inserts and fixes the tightening end of the lateral, end chain. It is a junction with one end of the lateral, the end chain and two cross-diagonal chains permanently connected to the snow chain.
Splošna naloga predmetne naprave je potemtakem, sprejeti prosti, zategovalni konec bočne, sklepne verige, tega po zategnitvi zadržati v napetem stanju in ga nato - ko gre za snemanje snežne verige s kolesa - sprostiti.The overall task of the device in question is, therefore, to accept the free, tightening end of the lateral, end chain, to keep it in tension after tightening and then to release it when it comes to removing the snow chain.
Dejstvo, da so v stičišče, v katerega je vgrajena predmetna naprava, pri snežni verigi speljane in trajno priključene tri verige, ni zadržek za uporabo predmeta izuma v kakem drugem primeru, ko bi šlo za trajno zvezo naprave z dvema ali z eno samo verigo.The fact that three chains are connected and permanently attached to the junction in which the device is incorporated into the snow chain is not a restriction for the use of the object of the invention in any other case where it is a permanent connection of the device with two or a single chain.
Zgoraj podana splošna naloga je v stanju tehnike rešena na več načinov.The above general problem is solved in the prior art in several ways.
Iz patentne prijave P 39 06 486.7 (Franklin), vložene v ZRN, je znana naprava, katere bistvo je v tem, da je nasproti vrtljivemu verižniku (verižnemu kolesu) sprejemno-vodilnega dela naprave, ki kontrolirano vodi ovalnočlenkasto verigo, postavljen ovzmeten vzvod, katerega sestavni del je zobec za uprijem v svetlino členka verige, nahajajočega se plosko nasproti zobu.From patent application P 39 06 486.7 (Franklin), filed in the Federal Republic of Germany, a device is known, the essence of which is that a suspension lever is mounted opposite the rotating sprocket (chain wheel) of the receiver-guide portion of the device which controls the oval-chain chain in a controlled manner, the component of which is a pinion for resisting the brightness of the link of the chain opposite to the tooth.
Pomanjkljivost te rešitve je, med drugimi, v tem, da zobec lahko uprijema samo v vsak drugi členek verige, kar - v izogib izrazitim omejitvam pri zategovanju (zategovanje je stopenjsko) - pomeni, da je proizvajalec snežnih verig prisiljen uporabiti verigo iz čimmanjŠih členkov, kot tudi v samem zobcu, ki je kot tak potencialno najšibkejši del naprave - tem bolj, čim manjši so členki verige.The disadvantage of this solution is, inter alia, that the tooth can only rest on every other link in the chain, which - in order to avoid severe tightening restrictions (tightening is stepped) - means that the snow chain manufacturer is forced to use the chain from the smallest link, as well as in the tooth itself, which, as such, is potentially the weakest part of the device - especially, the smaller the links in the chain.
Iz proizvodnega programa tvrdke KONIG S.p.A. (22047 Molteno(Co), Italija) in OTTINGER GmbH (7703 Rielasingen, Nemčija) kot tudi iz programa titularja pričujoče prijave so znane v osnovi medsebojno enake naprave zadevne vrste, ki so proti zgoraj omenjeni napravi racionalizirane do te mere, da vlogo verižnika (verižnega kolesa) pri sprejemno-vodilnem delu naprave prevzame verižno vodilo, ki ga tvorita obojestransko globokovlečeni, medsebojno središčno spojeni ohišni stranici (verižnega kolesa kot vrtljivega elementa sprejemno-vodilnega dela naprave torej ni več), za potrebe blokiranja verige proti verižnemu vodilu pa je uporabljen širokorob prosti konec prav tako ovzmetenega, zasučno vgrajenega zapornega vzvoda, ki s svojim naleganjem na obodni rob verižnega vodila s slednjim tvori/določa ležišče za plosko nalegajoč členek verige. Ta je tudi v teh primerih kontrolirano vodena.From the production program of the KONIG hardcover S.p.A. (22047 Molteno (Co), Italy) and OTTINGER GmbH (7703 Rielasingen, Germany), as well as from the titular program of the present application, are known essentially identical devices of the type concerned, which are rationalized to the extent that the chain-linker ( chain wheel) at the receiving-guide part of the device takes the chain guide, which is formed by two deep-drawn, centrally connected housing sides (the chain wheel is no longer a rotating element of the receiver-guide part of the device), and is used for blocking the chain against the chain guide wide-open free end of a also suspended, pivotally mounted locking lever, which by its attachment to the circumferential edge of the chain guide with the latter forms / determines the bearing for a flat-linking chain link. In these cases it is also controlled in a controlled manner.
Očitno je, da gre tudi pri teh rešitvah za blokiranje verige samo preko vsakega drugega členka.Obviously, these blockchain solutions also go through every other link.
Izum je osnovan na okoliščini, da so zgradbotvorni verižni odseki pri snežnih verigah rabljeni in obremenjeni drugače, kot je to za verige kot linijske, definirano vodene in samo natezno obremenjene strojne elemente predvideno v teoriji in standardih. Prej kot sama natezna trdnost verižnih odsekov, ki je npr. poleg kalibriranosti glavno vodilo pri izbiri verig po teoriji in standardih, je za uporabo verižnih odsekov pri snežnih verigah odločilna njihova obrabna trdnost in nerjavnost, pri čemer velikost Členka, ki se jo tu obravnava kot izrazito geometrijsko (in ne kot trdnostno) danost, gotovo ni stvar, ki bi jo pri snežnih verigah lahko imeli za brezpredmetno.The invention is based on the fact that the chain-link sections of the snow chains are used and loaded differently than for the chains as linear, defined-guided and only tensile-loaded machine elements provided in theory and standards. Rather than the tensile strength of chain sections, e.g. in addition to calibration, the main guide in the choice of chains by theory and standards, the use of chain sections in snow chains is decisive for their wear and tear strength, with the size of the joint considered here as a distinct geometric (rather than a solid) given a thing that could be considered meaningless with snow chains.
V zvezi s tem je za kreiranje izuma odločilno spoznanje, da snežna veriga pravzaprav v ničemer ne pogojuje strogo kontroliranega vodenja posameznih členkov - v smislu zasuka le-teh glede na vzdolžno os verige, ko gre pri predmetni napravi za vstavljanje in držanje zategovalnega konca bočne, sklepne verige snežne verige v vgrajenem stanju slednje. Ocenjuje se, da je vztrajanje na strogo kontroliranem vodenju zategovalnega konca bočne, sklepne verige snežne verige po stanju tehnike tehnično neosnovano.In this connection, it is decisive for the creation of the invention that the snow chain does not in any way condition the strictly controlled running of the individual joints - in terms of rotation of them with respect to the longitudinal axis of the chain, when the device in question is for inserting and holding the tightening end of the side, snow chain joints in the built-in condition of the latter. It is estimated that the insistence on strictly controlled running of the tightening end of the lateral, articulated snow chain is technically unfounded by the state of the art.
Temelj pričujočega izumljanja je torej vprašanje, kako zasnovati protipovratno, hoteno popustljivo napravo, prednostno, a ne izključno, za sprejem in držanje zategovalnega konca bočne, sklepne verige v verižnem stičišču snežne verige, da se bo z njo (= z napravo) dalo zategovalni konec bočne, sklepne verige pridržati v katerem koli (torej vsakem) njenem členku; za tem vprašanjem pa se seveda skriva težnja po imeti prosto pot pri izbiri velikosti členka verige, kar utegne biti odločilnega pomena npr. pri motorno gnanih mobilnih delovnih strojih, pri katerih je mnogokrat treba kolesa opremiti s (tedaj) blatnimi verigami, ki bi v drobnočlenski izvedbi kaj lahko odpovedale.The basis of the present invention is therefore the question of how to design a non-returnable, willingly indulgent device, preferably, but not exclusively, to receive and hold the tightening end of the lateral, end chain in the chain-link of the snow chain so that it (= with the device) will be provided with a tightening end retain the side, end chains in any (therefore each) of its joints; this issue, of course, has a tendency to have a free path when choosing the size of a chain link, which may be crucial, for example. motor driven mobile work machines that often require wheels to be equipped with (then) mud chains that could fail in the smallest possible version.
Spoznanje, da pri kreiranju izuma nismo vezani na pogoj, strogo kontrolirano voditi verigo (veriga se torej pri vstavljanju sme - seveda v razumnem obsegu - sukati), nudi na presenetljivo preprost način številne možnosti reševanja zgoraj navedenega problema.The realization that we are not bound by the condition of a strictly controlled chain in the creation of the invention (the chain may therefore - in a reasonable extent - twist when inserting), offers, in a surprisingly simple way, numerous possibilities for solving the above problem.
Splošna rešitev problema, na katerem temelji izumljanje, je zajeta s patentnimi zahtevki, ki sledijo pričujočemu opisu in ki jih je - vsaj preliminarno - razumeti kot sestavni del opisa (racionalnostni razlogi).The general solution to the problem underlying the invention is covered by the claims which follow the present description and which - at least preliminary - can be understood as an integral part of the description (rational reasons).

Sl. 1 (zgolj v načelno ilustracijo problemskega stanja) kaže snežno verigo, ki obsega segmentiran obroč 1 stalne dolžine, ki se nahaja na zadnji/notranji strani Z kolesa in ki se pri montaži na kolo poveže v brezkončno obliko s pomočjo kaveljske naprave 2, nadalje njemu nasproti razporejen in v sklenjenem stanju z njim soosen nadaljnji, v tem slučaju verižni, obroč 3, ki se nahaja na prednji/zunanji strani P kolesa in ki se pri montaži na kolo poveže v brezkončno stanje s pomočjo (na skici uokvirjene) naprave, ki je predmet pričujoče prijave, ter mrežni sistem 4 prečno-diagonalnih in obodnih verižnih odsekov, ki je vpet med obroča 1, 3 in zasnovan tako, da je v celoti tvorjena rotacijsko zaključena mrežna zgradba s četverokotnimi mrežnimi polji.FIG. 1 (for illustrative purposes only) illustrates a snow chain comprising a segmented ring 1 of constant length, which is located on the rear / inner side Z of the wheel and which, when mounted on a bicycle, is connected to a continuous form by means of a hook device 2, further to it opposite, arranged in a closed state, a further, in this case chain, ring 3, which is located on the front / outer side of the P wheel and which, when mounted on the wheel, is connected to an infinite state by means of a (framed) device which is the subject of the present application, and a mesh system 4 of diagonal and circumferential chain sections, which is clamped between rings 1, 3 and designed to be a fully formed rotationally completed mesh structure with quadrilateral mesh fields.
V praksi je računati s tem, da je guma lahko bolj ali manj napolnjena. Snežna veriga pa mora kljub temu omogočati objemno prilagodljivost k dani napolnjenosti le-te.In practice, it is considered that the tire may be more or less filled. However, the snow chain must allow for flexible adaptation to the given charge.
To je pri snežni verigi na splošno omogočeno s tem, da eno od verižnih stičišč vzdolž verižnega obroča 3 tvori naprava, ki je predmet izuma, pri čemer je nasproti zadevni napravi nahajajoči se prosti, po svoji vlogi zategovalni, konec 5 bočne, sklepne verige, ki v vgrajenem stanju tvori verižni obroč 3, predviden za sodelovanje z zadevno napravo, je v nadaljnjem razumno dolg in na svojem prostem koncu opremljen z elastično-kompenzacijsko kaveljsko napravo 6.In the snow chain, this is generally made possible by the fact that one of the chain junctions along the chain ring 3 is formed by the device of the invention, with the free end of the lateral chain, 5, of the lateral chain, opposite to the device in question. which, when fitted, forms a chain ring 3 intended to cooperate with the device in question is further reasonably long and, at its free end, provided with an elastic-compensating hook device 6.
V primerih, ko na skicah ni sklicevalne številke, v opisu pa se navaja, se glede označevanja elementov v opisovanju izvedbenih primerov predmetne naprave držimo naslednjega načela: Številke glavnih delov so dvomestne, dodatne razlikovalne oznake niso izključene. Prva številka označuje zaporedno številko izvedbenega primera (teh je, kot izhaja iz liste skic, osmero, poleg njih pa so tu še tri modifikacije), druga pa v vseh izvedbenih primerih istorodni oz. istonamenski element (ničla je rezervirana za označevanje naprave kot celote).In cases where there is no reference number in the drawings but in the description, the following principle is observed with respect to the marking of the elements in the description of the embodiments of the device in question: Main part numbers are two-digit, additional distinguishing marks are not excluded. The first number indicates the sequence number of the implementation case (there are eight of them, as shown in the list of sketches, and there are three modifications in addition to them), and the second, in all the implementation cases, is the same or. eponymous element (zero is reserved to indicate the device as a whole).
Izvedbeni primeri so razporejeni v skupine po tipičnih značilnostih, vezanih na obliko izhodiščnega materiala in tehnologijo izdelave (dasiravno so možne tudi delitve po drugih vidikih, o katerih bo govor sproti). Kot prva je na vrsti skupina naprav (sl. 2 doThe implementation examples are grouped according to typical characteristics related to the form of the starting material and the manufacturing technology (divisions by other aspects will be discussed as well, which will be discussed on an ongoing basis). The first is the group of devices (Fig. 2 to
13), za katere je značilno, da sestojijo iz samo dveh sestavnih delov, pri čemer sta oba narejena iz ploščatega izhodiščnega gradiva in po proizvodni tehnologiji, ki je za oba elementa ista.13), characterized in that they consist of only two components, both of which are made of flat starting material and according to production technology, which is the same for the two elements.
Sl. 2 do 4 kažejo osnovno izvedbeno obliko protipovratne, hoteno popustljive naprave za sprejem in držanje napete verige v verižnem stičišču po izumu. Naprava 10 obsega zapahnilni del 11 in sprejemno-vodilni del 12, ki sta zasnovana in medsebojno sodelujeta, kot sledi.FIG. 2 to 4 show a basic embodiment of a non-returnable, permissively indulgent device for receiving and holding a tension chain in a chain junction according to the invention. The apparatus 10 comprises a locking portion 11 and a guide portion 12, which are designed and cooperated as follows.
Zapahnilni del 11 je v bistvu trisegmenten: Na raven vlečni segment 13 je v njegovi dolžinski razsežnosti, v bistvu pravokotno nanj, postavljen vezni segment 14 enake širine, nanj pa je - spet v bistvu pravokotno, vendar proč od vlečnega segmenta 13 postavljen blokirni segment 15, ki je širši od predhodnih dveh segmentov 13,14. Taje na sredini svoje dolžine prečno na dolžinsko razsežnost strehasto lomljen (notranji kot strehe velikosti okoli 120°) in v območju slemena 15’ zasnovan z izrezom 16, zasnovanim v bistvu kot prečno potekajoč pravokotnik. Izrez 16 kot tak pri funkcioniranju naprave ni soudeležen. Čelni rob 15” blokimega segmenta 15 je konkavno usločen in vzdolž tega roba potekajoči materialni odsek 17 segmenta 15 je za velikostni red lastne debeline ločno vdrt. V predstavljeni zasnovi naprave 10 čelnemu robu 15” sosedni rob izreza 16 sledi vzporedno, torej ločno, preostale tri stranice izreza 16 pa so v tem primeru ravne.The locking part 11 is essentially three-segmented: On a level traction segment 13, in its longitudinal dimension, substantially perpendicular to it, there is a connecting segment 14 of equal width, and on it - again essentially perpendicular, but away from the traction segment 13 a blocking segment 15 is placed. , which is wider than the previous two segments 13.14. Then, in the middle of its length, it is transversely broken in length by a roof (internal angle of the roof about 120 ° in size) and in the ridge area 15 'formed by a recess 16, designed essentially as a transverse rectangle. Cutout 16 as such is not involved in the operation of the device. The leading edge 15 ”of the block segment 15 is concave and, along this edge, the material section 17 of the segment 15 extends individually for the size order of its thickness. In the presented design of the device 10, the adjacent edge 15 "of the cutout 16 follows in parallel, ie separately, with the remaining three sides of the cutout 16 being straight in this case.
Sprejemno-vodilni del 12 naprave 10 je v bistvu enostavna plošča z dvema izrezoma: Izrezu 18, kije, z ohlapnostjo, prirejen veznemu segmentu 13 zapahnilnega dela 11 in je zato pravokotnorežast, sledi v dolžinski orientaciji, z odmikom, okrogel izrez 19, katerega premer je velikostnega reda širine segmentov 13,14 zapahnilnega dela 11 in ki služi kot prehod za zategovalni konec 5 bočne, sklepne verige snežne verige. Vzdolž izreza 19 potekajoči čelni materialni odsek 12’ dela 12 je za velikostni red lastne debeline ločno izbočen, torej ukrivljen nasprotno ukrivljenosti materialnega odseka 17 zapahnilnega dela 11, tako da se krivinska ekstrema odsekov 17 in 12’ nahajata v bistvu v isti ravnini - ravnini, ki je vzporedna s sistemsko ravnino sprejemno-vodilnega dela 12.The receiving-guiding part 12 of the device 10 is essentially a simple plate with two notches: a notch 18, which, with a slack, is adapted to the connecting segment 13 of the locking part 11 and is therefore rectangular, followed in longitudinal orientation by an offset, a circular notch 19 whose diameter is of the order of segment width 13.14 of the locking portion 11 and serves as a passage for the tightening end 5 of the lateral, articulated snow chain. Along the cutout 19, the running front material section 12 'of the part 12 is individually convex for the size order of its thickness, that is, curved opposite to the curvature of the material section 17 of the locking part 11 so that the curvature extremes of the sections 17 and 12' are substantially in the same plane, which is parallel to the system plane of the receiver-guide portion 12.
Zapahnilni del 11 je tako vložen v sprejemno-vodilni del 12, da se vlečni segment 13 dela 11 nahaja na tisti strani sprejemno-vodilnega dela 12, kjer se nahaja vdrtina (konkavna stran) čelnega odseka 12’ dela 12, blokimi segment 15 dela 11 se nahaja na ravno nasprotni strani dela 12 in vezni segment 14 dela 11 se nahaja v pravokotnorežastem izrezu 18 dela 12.The locking part 11 is so inserted into the receiving-guiding part 12 that the traction segment 13 of the part 11 is located on the side of the receiving-guiding part 12, where there is a recess (concave side) of the front section 12 'of the part 12, block segment 15 of the part 11 is located on the exactly opposite side of part 12 and the connecting segment 14 of part 11 is located in a rectangular notch 18 of part 12.
Pri navedeni medsebojni legi delov 11, 12 sta ločno vdrti odsek 17 dela 11 in okrogli izrez 19 dela 12 medsebojno v nadaljnjem tako postavljena, da čelni konkavni rob 15” dela 11 in njemu nasproti nahajajoči se del obodnega roba krožnega izreza 19 dela 12 tvorita v bistvu lečasto ležišče 10’ (sl. 4), katerega velikost je tako opredeljena, da skozenj ravno še gre po svoji najkrajši zunanji razsežnosti a (sl. 3) členek zategovalnega konca 5 bočne, sklepne verige snežne verige v legi, ko je ploska stran členka v bistvu pravokotna na vzdolžno os naprave 10. Pri tem je največja razsežnost lečastega ležišča 10’ smotrno manjša od premera izreza 19.In the said inter-position of the parts 11, 12, the section 17 of the part 11 is individually indented and the circular neckline 19 of the part 12 is positioned in such a way that the front concave edge 15 ”of the part 11 and the opposite part of the circumferential edge of the circular neck 19 of the part 12 form a substantially lenticular bearing 10 '(Fig. 4), the size of which is so defined that it goes straight through its shortest outer dimension a (Fig. 3) of the clamping end 5 of the lateral, chain-linking snow chain in position when flat the articulation is substantially perpendicular to the longitudinal axis of the device 10. In this case, the maximum dimension of the bearing bed 10 'is substantially smaller than the diameter of the cutout 19.
Vlečni segment 13 zapahnilnega dela 11 ima v območju svojega prostega konca priključni izrez 13’ za - v tem primeru neločljivo - priključitev konca bočne, sklepne verige snežne verige. Za priključitev prečno-diagonalnih verig snežne verige v zadevnem stičišču je sprejemno-vodilni del 12 naprave 10, smotrno v območju izven projekcije zapahnilnega dela 11, zasnovan z dvojico priključnih izrezov 12” za priključitev vozliščnega členka, na katerega se priključita omenjeni verigi. Sistemska os vozliščnega členka je v tem primeru postavljena pravokotno na sistemsko os zadevne naprave (sl. 4).The towing segment 13 of the locking portion 11 has, in the area of its free end, a connecting notch 13 'for - in this case inseparable - connection of the end of the lateral, end chain of the snow chain. To connect the diagonal chains of the snow chain at the respective junction, the receiving-guide portion 12 of the device 10, preferably in the area outside the projection of the locking portion 11, is designed with two connecting notches 12 ”to connect the hub to which the chains are connected. In this case, the system axis of the node joint is perpendicular to the system axis of the device concerned (Fig. 4).
Očitno je, da na izreza 12” in izrez 13’ priključena vozliščni členek in veriga v območju naprave 10 definirata ravnino delovanja nateznih sil Fl, F2 (slednja kot rezultanta sil dveh prečno-diagonalnih verig) in da je orientacija vkleščenega členka vpeljane in blokirane verige, v tem slučaju zategovalnega konca 5 bočne, sklepne verige, v bistvu pravokotna na to ravnino.It is obvious that the notch 12 'and the notch 13' connected to the knot and chain in the region of the device 10 define the plane of action of the tensile forces Fl, F2 (the latter as a result of the forces of two cross-diagonal chains) and that the orientation of the twisted link of the introduced and blocked chains , in this case, the tightening end 5 of the lateral, end chain, substantially perpendicular to that plane.
S sl. 3 izhaja, da napenjalna sila F3 zategovalnega konca 5 bočne, sklepne verige snežne verige deluje pod sprejemno-vodilnim delom 12. Praktično - če zanemarimo vpliv (manj izdatne) sile F4 pomožnega fiksiranja prostega odseka zategovalnega konca 5 bočne, sklepne verige snežne verige - tri sile Fl, F2 (ta kot rezultanta dveh sil) in F3 opredeljujejo skupno ravnino, ki leži izven ravnine sprejemno-vodilnega dela 12. Na dlani je, da se pri opisanem obremenitvenem stanju v napravi 10 pojavi moment, ki čelni, ločno vdrti odsek 17 blokirnega segmenta 15 dela 11 in čelni odsekFIG. 3 shows that the tensile force F3 of the tightening end 5 of the lateral, snow chain joint chain operates below the receiving-guide part 12. Practically - neglecting the influence of the (less abundant) force F4 of auxiliary fixing of the free section of the tightening end 5 of the lateral, chain snow chain - three forces Fl, F2 (this as a result of two forces) and F3 define the common plane that lies outside the plane of the receiving-guide portion 12. It is at the palm of the hand that, at the described load condition, a moment appears in the device 10, which individually engages the section 17 the blocking segment 15 of part 11 and the front section
12’ sprejemno-vodilnega dela 12 tišči drugega k drugemu, s čimer je zagotovljena trajna prisotnost lečastega ležišča 10’. V tem je bistvo blokirnega varovanja zategnjenega zategovalnega konca 5 bočne, sklepne verige snežne verige po izumu. Naprava 10 se ne razklene in lečasto ležišče 10’ ne razpade, dokler se ne pojavi nasprotni moment oz. nova sila, delujoča npr. pravokotno na ravnino delovanja sil Fl, F2, F3 za dosego spremembe medsebojnega položaja delov 11,12.12 'of the receiving-guide portion 12 presses against each other, thereby ensuring the permanent presence of the bearing bed 10'. This is the key to blocking the tightening end of the 5, lateral chain of the snow chain according to the invention. The device 10 does not unlock and the lens bed 10 'does not disintegrate until the opposite moment or. a new force, acting e.g. perpendicular to the plane of action of the forces Fl, F2, F3 to achieve a change in the mutual position of the parts 11,12.
Dejansko protipovratno držanje zategnjenega zategovalnega konca 5 bočne, sklepne verige snežne verige je vzpostavljeno v bistvu oblikosklepno: členku verige, nahajajočemu se v lečastem ležišču 10’, sledeči zgornji členek, ki je glede prvega po osi seveda zasukan za 90°, pod vplivom sile F3 naleže na odseka 12’, 17 delov 12, 11 naprave 10 (za lažjo predstavo prim. stanje po sl. 18).In fact, the backward holding of the tightened tightening end 5 of the lateral, snowmobile chain is substantially shaped in the form of: a chain link located in the lens bed 10 ', the following upper link, of course rotated 90 ° by the first axis, under the influence of force F3 it rests on sections 12 ', 17 of parts 12, 11 of device 10 (for ease of reference, see the state of Fig. 18).
Poskusi z materializiranimi prototipi kažejo, da se da pri delih 11, 12 vzpostaviti tako razmerje ročic, da za razklenitev napete naprave 10 ni potrebna niti pretirano velika sila (predvideva se uporaba moči prstov moške roke) niti pretirano velik zasučni hod delov 11, 12 (za lažjo predstavo primerjaj stanje po sl. 20). Razen tega po izumu ni nemogoče predvideti sredstva za olajšanje deblokiranja (pobliže pojasnjeno npr. v zvezi s sl. 31 do 33).Experiments with materialized prototypes show that parts 11, 12 can be adjusted in such a way that there is no need to force too much force (assuming the use of the power of the fingers of a male hand) or excessively large rotation of parts 11, 12 ( compare the situation in Fig. 20) for an easier idea. In addition, it is not possible to provide for means of unblocking according to the invention (for example, in more detail, with reference to Figures 31 to 33).
Cilj izuma, omogočiti blokiranje pri katerem koli členku verige, je dosežen preprosto s tem, da v sproščenem stanju naprave 10, ko lečastega ležišča 10’ ni, gibanje vstavljajoče verige v ničemer ni posebej ovirano, torej se lahko, če je treba, veriga od členka do členka tudi poljubno zasuka. Ko je zategovalni konec 5 bočne, sklepne verige snežne verige zategnjen in vlečno silo popustimo, naprava, predtem razklenjena, sama od sebe vzpostavi lečasto ležišče 10’ in v njem zaobjame tam nahajajoči se členek verige.The object of the invention is to enable blocking at any link of the chain simply by the fact that in the relaxed state of the device 10, when there is no locked bearing 10 ', the movement of the insertion chain is not particularly impeded; articulation to articulation also rotates as desired. When the tightening end 5 of the lateral, chain link of the snow chain is tightened and the towing force is loosened, the device, previously unlocked, establishes a lens bed 10 'by itself and encloses the chain link therein.
Sl. 5 do sl. 7 kažejo napravo 20 (to samo v prostorski projekciji) in modificirano napravo 20’ (to samo v dveh ortogonalnih projekcijah) kot izvedbeni možnosti, ki se od one s sl. 2 do 4 razlikujeta v naslednjih značilnostih: Vezni segment 24, 24a in blokirni segment 25,25a zapahnilnega dela 21, 21a vzajemno tvorita zvezno ukrivljen ločni del, ki je na vlečni segment 23, 23a zapahnilnega dela 21, 21a priključen tako, da vznožje veznega segmenta 24, 24a z vlečnim segmentom 23, 23a (v bistvu tudi s sprejemno-vodilnim delom 22, 22a) oklepa kot velikosti okoli 120° (sl. 6); pri tem čelni odsek 27, 27a zapahnilnega dela 21, 21a glede na vlečni segment 23, 23a le-tega ohranja dvonivojskost - kot pri predhodnem izvedbenem primeru. Izrez 26, 26a, ki tudi tu pri funkcioniranju naprave ni soudeležen, zavzema polje med temensko linijo zgoraj omenjenega ločnega dela in čelnim odsekom 27, 27a. Izrez 29, 29a je tu zasnovan kot kombinacija v bistvu pravokotnega - ta delež meji na čelni odsek 22’, 22’a in polkrožnega deleža, pri čemer se slednji nahaja pod blokimim segmentom 25, 25a. Odsek sprejemno-vodilnega dela 22, 22a, v katerem je predviden izrez 22”, 22”a za trajno, vrtljivo priključitev kavlja za obešenje prečno-diagonalnih verig, je tu pravokotno zapognjen v smeri proč od blokirnega segmenta 25, 25a, razen tega pa v tlorisni projekciji (sl. 7) postavljen tako, da smeri sil Fl in F2 (analogija s sl. 4) oklepata kot velikosti okoli 75°. Izvedbi po sl. 5 in njena modifikacija po sl. 6-7 se medsebojno razlikujeta le po zasnovi čelnega roba čelnega odseka 27, 27a zapahnilnega dela 21, 21a (in po iz tega izvirajoči zasnovi blokirnega ležišča 20’, 20’a). Pri izvedbi po sl. 5 je omenjeni čelni rob zasnovan podobno znaku { (z materialnim delom na desni), torej sestavljen iz dveh konkavno zasnovanih pododsekov z vmesno središčno konico, pri izvedbi po sl. 6-7 pa je ta enak izvedbi po sl. 2-4. Za razliko od naprave 10 (sl. 2 do 4), pri kateri je blokirni segment 15 v vzdolžni smeri konstantne širine, se širina blokirnega segmenta 25, 25a tu predstavljenih naprav 20, 20a v smeri proti čelnemu odseku 27, 27a zvezno veča.FIG. 5 to FIG. 7 show a device 20 (this in spatial projection only) and a modified device 20 '(only in two orthogonal projections) as embodiments of which from FIG. 2 to 4 differ in the following characteristics: The connecting segment 24, 24a and the locking segment 25,25a of the locking portion 21, 21a mutually form a federally curved detached portion which is connected to the towing segment 23, 23a of the locking portion 21, 21a such that the base of the connecting the segments 24, 24a with the towing segment 23, 23a (substantially also with the guide portion 22, 22a) encloses an angle of magnitude of about 120 ° (Fig. 6); in this case, the front section 27, 27a of the locking part 21, 21a with respect to the towing segment 23, 23a retains a two-tier - as in the previous embodiment. The cutout 26, 26a, which is not involved in the operation of the device here, occupies the field between the top line of the abovementioned separate part and the front section 27, 27a. The cutout 29, 29a is designed here as a combination of essentially rectangular - this portion borders on the front section 22 ', 22′a and the semicircular portion, the latter being located below the block segment 25, 25a. The section of the guide portion 22, 22a, in which a cutout 22 ”, 22” a is provided for a permanent, rotatable connection of the hook for hanging the diagonal chains, is here bent perpendicularly away from the blocking segment 25, 25a, except that in the floor plan (Fig. 7) positioned such that the direction of the forces Fl and F2 (analogy to Fig. 4) enclose angle of magnitude about 75 °. The embodiments of FIG. 5 and its modification according to FIG. 6-7 differ only in the design of the leading edge of the front section 27, 27a of the locking portion 21, 21a (and the consequent design of the locking bed 20 ', 20'a). In the embodiment of FIG. 5, said front edge is designed similarly to the sign {(with material part on the right), thus consisting of two concavely designed subsections with an intermediate center tip, in the embodiment of FIG. 6-7, however, is identical to the embodiment of FIG. 2-4. Unlike the device 10 (Figs. 2 to 4), in which the locking segment 15 is in the longitudinal direction of constant width, the width of the locking segment 25, 25a of the devices 20, 20a presented here in the direction towards the front section 27, 27a is continuously increased.
Sl. 8 do sl. 10 kažejo napravo 30, katere zapahnilni del 31 obsega ploščat vlečni segment 33, ki je vzdolž sistemske osi podolgovato izrezan, pri čemer ima izrez 33’ proti eni bočni strani segmenta 33 prost izhod, tako da z izrezom 33’ zasnovani vlečni segment spominja na kavelj in kot tak je tudi namenjen. V danem slučaju (sl. 10) sta na vlečni segment 33 v območju izreza 33’ priključena tako bočna, sklepna veriga kot tudi - pravokotno na prvo - vozliščni členek za sprejem prečno-diagonalnih verig snežne verige. Posebnost naprave 30 v primeijavi s predhodnimi napravami je torej najprej ta, da je sprejemno-vodilni del 32 naprave 30 predviden za sprejem zgolj zategovalnega konca 5 bočne, sklepne verige.FIG. 8 to FIG. 10 shows a device 30 whose locking portion 31 comprises a flat towing segment 33 which is elongated cut along the system axis, the cutout 33 'having a free outlet 33 towards one side of the segment 33 such that the cutout 33' is designed to resemble a hook and as such it is also intended. In the present case (Fig. 10), both the lateral, the end chain and - perpendicularly to the first - the hub joint to receive the cross-diagonal chains of the snow chain are connected to the traction segment 33 in the region of the cutout 33 '. The peculiarity of the device 30 in comparison with the preceding devices is therefore first that the receiver-guide portion 32 of the device 30 is intended to receive only the tightening end 5 of the lateral, end chain.
V preostalem sta vlečni segment 33 in vezni segment 34 zapahnilnega dela 31 razporejena v bistvu enako kot njuna ekvivalenta (13, 14) pri napravi 10, medtem ko je blokirni segment 35, ki je tu scela (brez izreza), na pretežni svoji dolžini razporejen v ravnini, vzporedni z ravnino vlečnega segmenta 33, le njegov prednji, nad okroglim izrezom 39 sprejemno-vodilnega dela 32 nahajajoči se odsek se pod kotom velikosti okoli 45° spusti naprej proti sprejemno-vodilnemu delu 32, sam čelni odsek 37 pa se v bistvu spet zravna (sl. 9). Pri tem se širina nagnjenega prednjega odseka v smeri proti čelnemu odseku 37 zvezno oži (sl. 10). Ležišče 30’ za zategovalni konec 5 bočne, sklepne verige je v bistvu enako ležišču 10’ pri prvem izvedbenem primeru.For the rest, the towing segment 33 and the coupling segment 34 of the locking portion 31 are arranged substantially in the same way as their equivalents (13, 14) in the apparatus 10, while the locking segment 35, which is here (not cut), is arranged substantially in its length in a plane parallel to the plane of the traction segment 33, only its front, above the circular notch 39 of the receiving-guide portion 32, the extending section descends forward at an angle of about 45 ° towards the receiving-guide portion 32, and substantially the front section 37 itself substantially again straight (Fig. 9). In this case, the width of the inclined front section in the direction of the front section 37 is continuously narrowed (Fig. 10). Bearing 30 'for the tightening end 5 of the lateral, end chain is essentially the same as bearing 10' in the first embodiment.
SI. 11 do sl. 13 kažejo napravo 40, kije specifična po tem, daje ravnina delovanja sil Fl (na zapahnilnem delu 41) in F2 (na sprejemno-vodilnem delu 42) v bistvu ravnina sprejemno-vodilnega dela 42, in tem, da ima krožni izrez 49 sprejemno-vodilnega dela 42 v eno bočno stran prost izhod (sl. 13), tako da sprejemno-vodilni del 42 omogoča bočno vlaganje zategovalnega konca 5 bočne, sklepne verige. Prvoomenjena specifičnost je pri tem dosežena s tem, da se izreza 43’, 42”, ki predstavljata vrtilni ležišči za sprejem priključnih kavljev za obešenje verig snežne verige, nahajata na ustreznih zavihkih zapahnilnega dela 41 in sprejemno-vodilnega dela 42, postavljenih v bistvu pravokotno na sistemsko ravnino naprave 40.SI. 11 to FIG. 13 show a device 40 which is specific in that the plane of action of the forces Fl (on the locking portion 41) and F2 (on the receiving-guide portion 42) is essentially the plane of the receiving-guide portion 42, and that the circular cut-out 49 has of the guide portion 42 free exit in one side (Fig. 13), so that the guide portion 42 allows lateral insertion of the tightening end 5 of the lateral chain. The first-mentioned specificity is achieved by cutting out 43 ', 42', which are rotary bearings for receiving the hooks for hanging the snow chains, located on the respective tabs of the locking part 41 and the receiving-guide part 42, arranged substantially perpendicularly. to the system plane of the device 40.
V nadaljnjem opisani izvedbeni primer naprave in modifikacija le-te ohranjata dvodelnost, ko gre za funkcijo naprave, v konstrukcijskem pogledu pa gre pri njima za tri oz. Štiri sestavne dele.The following embodiment of the device and its modification preserve the two-part when it comes to the function of the device, and in the construction view they are three or three. Four components.
Posebnost naprave 50 po sl. 14 do sl. 16 je ta, da je vlečni segment 53 zapahnilnega dela 51 narejen ločeno od pločevinastega dela - iz paličastega gradiva, v danem primeru iz palice kvadratnega preseka, in ukrivljen v obliko členka verige, ki ni nujno sklenjen (sl. 15). Kot verižni členek zasnovani vlečni segment 53, ki je postavljen pravokotno na sistemsko ravnino naprave 50 in s svojo daljšo razsežnostjo usmerjen v smeri osi naprave 50, je vložen skozi njemu prirejen izrez 58 v veznem segmentu 54 in zatem s pločevinastim delom zapahnilnega dela 51 trajno spojen, npr. zvarjen, pri čemer se vezni segment 54 v vgrajenem stanju nahaja v območju blizu sredine dolžine členka, prednostno na polovici le-tega, usmerjeni proč od sprejemnovodilnega dela 52. In namesto pravokotnorežastega izreza, kakršen je bil v predhodnih izvedbah v sprejemno-vodilnem delu 52 predviden za sprejem veznega segmenta zapahnilnega dela, je tu v sprejemno-vodilnem delu 52 predviden izrez 58 kvadratne zasnove za sprejem in prosto nihajno premikanje členkastega vlečnega segmenta 53 in nanj vezanega pločevinastega dela zapahnilnega dela 51.The peculiarity of the device 50 according to FIG. 14 to FIG. 16 is that the towing segment 53 of the latching part 51 is made separately from the sheet metal portion - from the rod material, if necessary from the square section bar, and curved into the shape of a chain link, which is not necessarily contracted (Fig. 15). As a chain link designed towing segment 53, positioned perpendicularly to the system plane of the device 50 and directed with a longer dimension in the direction of the axis of the device 50, a cutout 58 in the connecting segment 54 is inserted through it and subsequently permanently connected to the sheet metal part of the locking portion 51. , e.g. welded, the connection segment 54 being in the mounted state in an area near the middle of the length of the joint, preferably half of it, directed away from the receiving guide portion 52. And instead of a rectangular cutout, as in the previous embodiments in the receiving guide portion 52 intended for receiving the locking segment of the locking portion, there is provided in the receiving-guide portion 52 a cutout 58 of a square design for receiving and free-swinging the articulated traction segment 53 and the sheet metal portion of the locking portion 51 thereto.
Specifičnost te izvedbe je tudi v tem, da je vozliščni členek za prenos sile F2 priključen na prvi členek verige za prenos sile F1 (sl. 16), in tako je tudi tu sprejemno-vodilni del 52 predviden le za sprejem zategovalnega konca 5 bočne, sklepne verige.The specificity of this embodiment is also that the force transmitter node F2 is connected to the first force transmitter chain member F1 (Fig. 16), and thus the receiver-guide portion 52 is provided here only for receiving the tightening end 5 of the lateral, of the chain.
Sl. 17 do sl. 20 kažejo modifikacijo predhodne izvedbe, katere bistvo je v tem, da je namesto zvamega spoja med pločevinastim in onim, kot členek zasnovanim delom zapahnilnega dela tu uporabljen oblikosklepni spoj, osnovan na tem, da na mestu združitve obeh delov pločevinasti del po objemnem zavihnjenju nerazdružno oklepa onega drugega. Specifičnost te izvedbe je v nadaljnjem ta, da je za potrebe dodatnega varovanja proti samodejnemu deblokiranju naprave (taka potreba pa v fazi prototipnih preizkusov ni bila izkazana za nujno potrebno in je zato ta možnost vključena v prijavo zgolj kot informacija o tem, da možnost dodatnega varovanja proti samodejnemu deblokiranju po izumu ni izključena) nakazana možnost uporabe elastično raztegljivega poveznega obroča 50”a. Ta je položajno varovan s tem, da je speljan skozi bočna izreza 55”a, predvidena v pločevinastem delu zapahnilnega dela 5 la.FIG. 17 to FIG. 20 show a modification of the previous embodiment, the essence of which is that instead of a twist joint between the sheet metal and the joint-shaped part of the locking part, a form-locking joint is used here, based on the fact that at the point of joining of the two parts, the sheet metal part inseparably wraps the other. The specificity of this embodiment is that for the purpose of additional protection against the automatic unblocking of the device (such a need was not proved to be absolutely necessary in the prototype testing phase and therefore this option is included in the application only as an indication that the possibility of additional security automatic unlocking according to the invention is not excluded) indicated the possibility of using an elastically extendable 50 "a connecting ring. This position is secured by being guided through the lateral recesses 55 ”a provided in the sheet metal portion of the locking portion 5 la.
Nadaljnji napravi, ki ju kažejo sl. 21 do sl. 23 oz. sl. 24 do sl. 26, sta spet zgolj dvokomponentni.The further devices shown in FIG. 21 to FIG. 23 oz. FIG. 24 to FIG. 26, again, are only two-component.
S konstrukcijskega vidika je naprava po sl. 21 do 23 specifična v tem, da je izhodiščni material za izdelavo ene od komponent, naprava po sl. 24 do 26 pa po tem, da je izhodiščni material za izdelavo obeh sestavnih delov palica okroglega preseka.From a structural point of view, the apparatus of FIG. 21 to 23 is specific in that the starting material for the manufacture of one of the components is the device of FIG. 24 to 26, in that the starting material for the manufacture of both components is a circular cross-section.
Sl. 21 do 23 kažejo napravo 70, katere zapahnilni del 71 je narejen v enem kosu iz ploščatega gradiva in zasnovan v bistvu tako, kot če bi združili blokimi segment 35 zapahnilnega dela 31 po sl. 8 do 10 in izrez 16 po sl. 2 do 4 in slednjega na eni bočni strani blokirnega segmenta 35 speljali ven (in s tem na eni bočni strani osamili ločni čelni odsek zapahnilnega dela), vlečni segment in vezni segment zapahnilnega dela, ki bi bila tu sprva koplanarna z ravnim delom blokirnega segmenta 35, pa bi glede na ravnino slednjega vzdolž sistemske osi naprave pravokotno zapognili in v njem predvideli drugega za drugim dva izreza 73’. Od teh je tisti, kije od čelnega odseka 77 bolj oddaljen, predviden za sprejem vozliščnega verižnega členka, oni drugi pa za sprejem sprejemno-vodilnega dela 72 naprave, ki je v tem primeru zasnovan preprosto kot O-obroč iz palice okroglega preseka. Med sprejemno-vodilnim delom 72 in čelnim odsekom 77 zapahnilnega dela 71 je v blokirnem položaju tudi tu vzpostavljeno lečasto ležišče 70’ (sl. 23).FIG. 21 to 23 show a device 70, the locking portion 71 of which is made in one piece of flat material and is designed essentially as if the block segment 35 of the locking portion 31 of FIG. 8 to 10 and cutout 16 of FIG. 2 to 4 and the latter on one side of the locking segment 35 are driven out (thereby isolating a separate front section of the locking part on one side), the towing segment and the locking part of the locking part, which would initially be coplanar with the flat part of the locking segment 35 , however, with respect to the plane of the latter, we would perpendicularly bend along the system axis of the device and make two cuts 73 'one after the other. Of these, the one further away from the front section 77 is intended to receive a knot chain link and the other to receive the receiver-guide portion 72 of the device, which in this case is designed simply as an O-ring from a circular cross-section bar. Between the receiving-guide portion 72 and the front section 77 of the locking portion 71, a lens bearing 70 ' is also provided in the blocking position here (Fig. 23).
V skupini dvokomponetnih naprav predstavlja presenetljivo preprosto rešitev naprava 80 po sl. 24 do 26. Vsaka od njenih komponent je narejena kot v sebi sklenjen element iz palice okroglega preseka in zasnovana kot sledi:In the group of two-component devices, the device 80 according to FIG. 24 to 26. Each of its components is made as a closed element from a circular cross section and is designed as follows:
Sprejemno-vodilni del 82 naprave 80 je v zasnovi členek pravokotniškega izgleda z zaokroženimi speljavami oglišč, katerega eno končno območje, ki je omejeno na razsežnost okoli tretjine daljše stranice omenjenega pravokotnika, je glede na preostali del pravokotno zapognjen, v danem primeru (sl. 25) gor. Zapahnilni del 81 pa v svoji zasnovi spominja na enoravninsko obrobo črke T (sl. 26), pri čemer so koti in vogali te obrobe prav tako zaokroženo speljani. Zunanja mera čez tisti del omenjene obrobe, ki zadeva pokončnico črke T, je prirejena notranji meri zgoraj omenjenega zapognjenega končnega območja sprejemno-vodilnega dela 82, pri čemer je v sestavljenem stanju naprave 80 zadnjeomenjeni del zapahnilnega dela 81 vtaknjen v omenjeno zapognjeno območje sprejemno-vodilnega dela 82. Ležišče 80’ za sprejem zategovalnega konca 5 bočne, sklepne verige je podobno ležišču 20’a naprave 20a (sl. T)·The receiver-guide portion 82 of the device 80 is in the design of a rectangular-shaped joint with rounded corners, whose end region, which is limited to a dimension about one third of the longer side of said rectangle, is perpendicularly bent with respect to the rest (Fig. 25 ) up. The locking part 81, in its design, is reminiscent of the one-plane border of the letter T (Fig. 26), and the corners and corners of these borders are also rounded. The outer dimension across that portion of said border, which relates to the letter T, is adapted to the inner dimension of the aforementioned folded end region of the receiving-guide portion 82, wherein in the assembled state of the device 80 the rear-end portion of the locking portion 81 is inserted into said folded region of the receiving-guide portion part 82. The bearing 80 'for receiving the tightening end 5 of the lateral, end chain is similar to the bearing 20'a of the device 20a (Fig. T) ·
Za vse doslej predstavljene izvedbe je veljala funkcijska shema, kakršna je nakazana na sl. 3-4, t.j., členek zategovalnega konca 5 bočne, sklepne verige, ki je vkleščen med sprejemno-vodilni del in zapahnilni del naprave, je po svoji dolgi stranici postavljen v bistvu pravokotno na ravnino delovanja sil Fl, F2. Da pa izum ni omejen na tako funkcijsko shemo, ponazarjata naslednja izvedbena primera.All the embodiments presented so far were subject to the functional scheme as shown in FIG. 3-4, i.e., the joint of the tightening end 5 of the lateral, articulated chain wedged between the receiving-guide portion and the locking portion of the device is positioned substantially perpendicular to the plane of action of the forces Fl, F2 along its long side. However, that the invention is not limited to such a functional scheme, the following embodiments illustrate.
Za napravo 90 po sl. 27 do sl. 29 in njeno modifikacijo - napravo 90a po sl. 31 do sl. 33 je za razliko od predhodnih naprav specifično, da v njunem funkcioniranju sodeluje tudi priključni verižni členek 100 oz. vozliščni členek lOOa, ki je skupen bočni, sklepni verigi in prečno-diagonalnima verigama snežne verige.For the device 90 of FIG. 27 to FIG. 29 and its modification - device 90a according to FIG. 31 to FIG. 33, unlike the previous devices, it is specific that the connection chain 100 or. a nodal joint lOOa common to the lateral, articulated chain and cross-diagonal chains of the snow chain.
Naprava 90, 90a obsega sprejemno-vodilni del 92, 92a, ki je narejen iz pločevinastega traku, ki je bil po svoji dolžinski razsežnosti najprej ukrivljen tako, da je dobil izgled, podoben znaku Π, katerega svetlina je prirejena zunanji krajši meri čez členek zategovalnega konca 5 bočne, sklepne verige, temu sledeče pa je trak utrpel še dve deformaciji: prosta kraka znaka n sta bila na odmiku od svojih prostih koncev v velikosti okoli polovice, raje več, njune dolžine s poševnim prehodom medsebojno zbližana do določenega razmika, in temenski, ločni del znaka n, sedaj gledano na trak od strani, je bil - ob ohranitvi obstoječega ločnega poteka iz prvotne ortogonalne projekcije - ločno vdrt. S tem je nastala smotrno zasnovana ločna drsna steza za vodenje zategovalnega konca 5 bočne, sklepne verige. Prosta konca tako zasnovanega sprejemno-vodilnega dela 92 sta na širinski razsežnosti, obsegajoči okoli polovico širine izhodiščnega traku, medsebojno skladno prirezana pod kotom okoli 45° (sl. 28), medtem ko sta prosta konca tako zasnovanega sprejemno-vodilnega dela 92a medsebojno skladno prirezana pod kotom okoli 45° po celi širinski razsežnosti izhodiščnega traku (sl. 32).The apparatus 90, 90a comprises a receiving-guiding portion 92, 92a, which is made of a sheet of tape, which, in its length dimension, is first curved to give a appearance similar to the sign katerega whose brightness is adapted externally to a short extent through the clamping member the ends 5 of the lateral, articulate chain, and then the ribbon suffered two more deformities: the free arms of the character n were at a distance of about half their size, preferring more, their lengths with an oblique passage converging to a certain distance, and the apex , the separate part of the character n, now viewed from the strip from the side, has been individually indented, while maintaining the existing distinct line from the original orthogonal projection. This has created a cleverly designed separate sliding track to guide the tightening end 5 of the side, articulated chain. The free ends of the transceiver 92 thus formed are, in a width extending about half the width of the initial strip, cut to one another at an angle of about 45 ° (FIG. 28), while the free ends of the transceiver 92a are cut apart at an angle of about 45 ° along the entire width of the reference strip (Fig. 32).
Zapahnilni del 91 naprave 90 je zasnovan kot enostavno ploščat podolgovat del (sl. 28), ki je na enem koncu poševno prirezan, tako da tam dobi obliko klina, pri čemer je vrh klina smotrno zaokrožen, drugi konec pa je zaključen z zaokrožitvijo, ki zajema celo širino elementa. V geometrijskem središču te zaokrožitve je predviden okrogel izrez 93’. Tudi zapahnilni del 91a naprave 90a je zasnovan kot ploščat podolgovat del (sl. 32) in tudi ta se na drugem koncu konča z zaokrožitvijo, ki zajema celo tamkajšnjo širino elementa, toda za razliko od predhodnega zapahnilnega dela, katerega širina je v osnovi (z izjemo klina in zaokrožitve) vseskozi enaka, se tu širina elementa v smeri proti prvemu koncu enakomerno zvezno veča, in omenjeni prvi konec je zasnovan z V-izrezom, tako da tam obstajata dva, glede na vzdolžno os elementa simetrično postavljena klina, in za razliko od krožnega izreza 93’ zapahnilnega dela 91 je tu predviden v bistvu polkrožen izrez 93’a, ki je zasukan tako, da je njegova diametralna stranica usmerjena proti vrhu tistega klina, ki se nahaja na strani ločne stranice izreza 93’a.The locking part 91 of the device 90 is designed as a simply flat elongated part (Fig. 28), which is obliquely trimmed at one end to give it a wedge shape, the tip of the wedge being substantially rounded and the other end terminated by a rounding which it covers the entire width of the element. In the geometric center of this rounding, a circular cutout of 93 'is foreseen. Also, the locking part 91a of the device 90a is designed as a flat elongated part (Fig. 32), and at the other end ends with a rounding that covers even the width of the element there, but unlike the previous locking part, the width of which is basically (with except for the wedge and rounding) is always the same, here the width of the element towards the first end increases uniformly continuously, and said first end is designed with a V-notch so that there are two wedges symmetrically placed with respect to the longitudinal axis of the element, and from circular cutout 93 'of the locking portion 91, a substantially semicircular cutout 93'a is provided here that is rotated so that its diametrical side is directed toward the top of that wedge located on the side of the separate side of cutout 93'a.
Zapahnilni del 91, 91a je vložen med prosta konca ploščatega sprejemno-vodilnega dela 92, 92a in pri tem razporejen tako, da je v položaju, ko on proti zategovalnemu koncu 5 bočne, sklepne verige izvaja protipovratno blokirno funkcijo, poševna stranica klina zapahnilnega dela 91 oz. poševna stranica tistega od dveh klinov zapahnilnega dela 91a, ki se nahaja na strani diametralne stranice izreza 93’a, vzporedna s profilnima robovoma sprejemno-vodilnega dela 92, 92a, medtem ko poševninski rob prostega konca sprejemno-vodilnega dela 92, 92a poteka v bistvi po tretjinskem do polovičnega ploskovnega odseka izreza 93’, 93’a.The locking portion 91, 91a is inserted between the free ends of the flat receiving-guide portion 92, 92a and is arranged so that, in the position when it exerts a counter-blocking function on the lateral chain 5, the oblique side of the locking pin wedge 91 oz. the oblique side of one of the two studs of the locking portion 91a, which is located on the side of the diametrical side of the recess 93'a, parallel to the profile edges of the receiving-guide portion 92, 92a, while the oblique edge of the free end of the receiving-guide portion 92, 92a extends substantially after a third to a half planar section of cut-out 93 ', 93'a.
Ob takem medsebojnem položaju zapahnilnega dela 91, 91a in sprejemno-vodilnega dela 92, 92a je v območju v bistvu razpolovišča dolžinske razsežnosti zapahnilnega dela 91, 91a razporejen tečaj, ki medsebojno povezuje zapahnilni del in sprejemnovodilni del in jima omogoča medsebojen relativen zasuk. Kar pa se tiče lokacije tečaja glede na širinsko razsežnost enega in drugega dela, je pri napravi 90 tečaj razporejen v bistvu na razpolovišču širine traku tako zapahnilnega kot tudi sprejemnovodilnega dela, medtem ko je tečaj pri napravi 90a pri njenem zapahnilnem delu 91a pomaknjen proti tisti njegovi vzdolžni stranici, ki je na strani diametralne stranice izreza 93’a, in pri njenem sprejemno-vodilnem delu 92a pomaknjen proti tisti njegovi strani, ki je v primerjavi z drugo stranjo zaradi prisotnosti poševnega prireza daljša.With such interlocking of the locking part 91, 91a and the receiving-guiding part 92, 92a, a hinge is arranged in the region of the half-length of the locking part length 91, 91a, which interconnects the locking part and the receiving guide part and enables them to be mutually relative rotation. As for the location of the hinge in relation to the width of one and the other part, the hinge 90 is arranged essentially at the half width of the strap of both the locking and receiving parts, while the hinge of the hinge 90a is shifted towards that hinge part thereof. the longitudinal side, which is on the side of the diametrical side of the cutout 93'a, and at its receiving-guide portion 92a, is displaced toward that side which is longer in comparison with the other side due to the presence of the oblique cut.
Tisti delež izreza 93’, 93’a, ki je v blokimem položaju po gornjem opisu prost (nezakrit od sprejemno-vodilnega dela 92, 92a), je po zgoraj omenjeni specifičnosti teh dveh izvedbenih primerov zavzet s priključnim verižnim členkom 100, lOOa, ki, kot jasno izhaja iz skic, s tem, ko se naslonita na poševna robova sprejemnovodilnega dela 92, 92a, služita kot omejevalnika zasuka zapahnilnega dela 91, 91a v fazi blokiranja zategovalnega konca 5 bočne, sklepne verige snežne verige.That portion of the cutout 93 ', 93'a which is free in the block position according to the above description (not covered by the guide portion 92, 92a) is, by the aforementioned specificity of these two embodiments, occupied by a connecting chain member 100, lOOa. , as is clear from the drawings, by leaning against the oblique edges of the receiving guide portion 92, 92a, they serve as limiters for the rotation of the locking portion 91, 91a during the locking phase of the tightening end 5 of the lateral, snow chain end chain.
Pri opisovanju izvedbenih primerov nismo posebej opozarjali na to, da, če bi se izkazalo za potrebno, lahko pri vsakem izvedbenem primeru predvidimo pomožne elemente, npr. ročaje, ročice, nastavke ipd., za olajšanje deblokiranja blokiranega zategovalnega konca 5 bočne, sklepne verige. Za ponazoritev dejstva, da taka možnost vedno obstaja, je tu predstavljena naprava 90a, katere drugi od dveh klinov je predviden za to, da z njegovo pomočjo razklenemo napravo 90a, ko hočemo blokirani zategovalni konec 5 bočne, sklepne verige deblokirati.In describing the embodiments, we did not specifically point out that, if deemed necessary, ancillary elements can be provided for each embodiment, e.g. handles, levers, attachments, etc., to facilitate the unlocking of the locking tightening end 5 of the lateral, articulated chain. To illustrate the fact that such a possibility always exists, a device 90a is presented here, the second of which is intended to unlock the device 90a by means of which it is necessary to unblock the tightening end 5 of the lateral, end chain.
Glede na okoliščino, da je izum nastal pri reševanju sistemskih problemov pri snežni verigi, je razumljivo, da so vsi zgoraj opisani izvedbeni primeri zadevne naprave usmerjeni k vprašanju sprejema, vodenja in držanja verige, v zvezi z njo zlasti ovalnočlenkaste. S tem pa se izum nikakor ne oddaljuje od vprašanj sprejema, vodenja in držanja verig drugačne vrste kakor tudi ne od vprašanj sprejema, vodenja in držanja, npr. na principu priščipnjenja, neverižnih linijskih elementov, bodisi takih, ki se jih jemlje za v bistvu toge in nestisljive, kot tudi gibkih oz. elastičnopodajnih. Pri slednjeomenjenih primerih uporabe predlagane naprave se osnovni nauk izuma ne menja, menjajo se le splošne konstrukcijske izvedbene značilnosti, ki pomenijo primerno adaptacijo zadevne naprave glede na dani priključni element.In view of the fact that the invention arose from the solution of systemic problems in the snow chain, it is understandable that all the embodiments described above of the device in question are directed to the issue of receiving, guiding and holding the chain, in particular the articulated chain. In this way, however, the invention in no way distracts from the issues of receiving, guiding and holding chains of a different kind, nor from the questions of receiving, guiding and holding, e.g. on the principle of adhesion, non-linear elements, or those which are considered to be substantially rigid and incompressible, as well as flexible or flexible. elastic feeders. In the latter cases of use of the proposed device, the basic doctrine of the invention does not change, only the general structural performance characteristics that mean a suitable adaptation of the device in question with respect to a given connection element are changed.
