Abstract

The subject of invention is a bridge link (i. e. "eight-shaped" link) for tyre chains especially chains used to prevent the tyre from sliding. The base of the link is a body (4) which has at least one connection hole (5, 6) for suspending other chain links. The longitudinal edges (19, 20) of the link body form a side surface for supporting the tyre or wear surface. Above the latter protrudes at least one profile section (21). The latter, on at least a part of its length, runs at an oblique angle with respect to plane (L) of the longitudinal centre of the discussed link, and extends practically over the entire length and width of the wear side (20), as the profile part (21) has at least two legs (22, 23) lying at a given angle one to another.

Description

Izum zadeva mostični člen za verige za gume po uvodnem delu Zahtevka 1.The invention relates to a bridge link for rubber chains according to the introductory part of Claim 1.

Znani mostični členi te vrste imajo ploščato telo Člena z več na obrabni strani mostičnega člena z razmikom druga za drugo ležečimi štrlinami oz. drug za drugim ležečimi glaviči, ki tvorijo profilni del. Navedeni elementi povečujejo grabljivost in ohranjanje smeri mostičnega člena. Med štrlinami so ustvarjene poglobitve, v katerih se pri uporabi mostičnega člena kaj lahko nabirajo zemlja, kamni ali pd. in se tam lahko ukleščijo. Grabljivost mostičnega člena se s tem poslabša. Pri surovih pogojih uporabe obstaja nevarnost, da se štrline odlomijo, tako da se grabljivost zmanjša.Known bridge members of this type have a flat body of a member with more on the wear side of the bridge member with spaced projections, respectively. one after the other, the headbands forming the profile part. These elements increase the grip and maintain the direction of the bridge link. Depths are created between the projections, in which, when using the bridge link, something can accumulate soil, stones or the like. and they can get stuck there. This makes the bridge link wear even worse. Under harsh conditions of use, there is a risk that the projections will break and thus reduce the rake.

Izum temelji na nalogi, mostični člen te vrste tako zasnovati, da zagotavlja dobro samočiščenje in celo pri ekstremnih pogojih uporabe visoko grabljivost.The invention is based on the task of designing a bridge member of this type so as to provide good self-cleaning and, even under extreme conditions of use, high durability.

Ta naloga je pri mostičnem členu take vrste, kot je opredeljena z uvodom Zahtevka 1, po izumu rešena z značilnostmi značilnostnega dela Zahtevka 1.This task is solved by the features of the characteristic part of Claim 1 in the bridge member of the type as defined by the introduction of Claim 1 according to the invention.

Pošev glede na vzdolžno središčno ravnino mostičnega člena potekajoči, izstopajoči del profila poskrbi za dobro grabljivost mostičnega člena. Ker ta element poteka poševno glede na vzdolžno središčno ravnino mostičnega člena, je lahko zasnovan kot neprekinjena štrlina, tako da se v njem ne morejo zadržati nikakršni kamni, zemlja in pd. Grabljivost je zato sleherni hip zagotovljena tudi pod neugodnimi razmerami uporabe. S takimi mostičnimi členi opremljena veriga za gume po zaslugi profilnega dela dobro drži smer.The slant with respect to the longitudinal center plane of the bridge member is a running, protruding part of the profile, which ensures good durability of the bridge member. As this element runs obliquely with respect to the longitudinal center plane of the bridge link, it can be designed as a continuous projection so that no stones, earth, etc. can be retained in it. Wearability is therefore guaranteed at all times even under adverse conditions of use. With such bridge links, the rubber chain, thanks to the profile section, holds the direction well.

Nadaljnje značilnosti izuma so razvidne iz nadaljnjih zahtevkov, opisa in skic.Further features of the invention are apparent from the following claims, description and drawings.

Izum je spodaj ob pomoči v skicah predstavljenega izvedbenega primera pobliže opisan. Pri tem kaže¹ sl. 1 mostični člen po izumu v pogledu od strani, sl. 2 mostični člen s sl. 1 v čelnem pogledu v smeri puščice II v sl. 1, sl. 3 mostični člen s sl. 1 v tlorisnem pogledu v smeri puščice III, in sl. 4 del verige za zaščito gume iz O členov in mostičnih členov po skicah sl. 1 do 3.The invention will now be described in more detail below with the help of the drawings of the embodiment shown below. In this, ¹ FIG. 1 is a side view of the bridge according to the invention; FIG. 2 is a bridge link in FIG. 1 in the front view in the direction of arrow II in FIG. 1, FIG. 3 is a bridge link in FIG. 1 is a plan view in the direction of arrow III, and FIG. 4 shows a section of the rubber chain of the O members and the bridge members according to the drawings FIG. 1 to 3.

Mostični člen 1 po skicah sl. 1 do 3 služi kot grabilni člen, ki ga z O obroči 2 (sl. 4) povežemo v člensko vezje verige 3 za zaščito gume oz. za zaščito proti drsenju gume.The bridge article 1 according to the drawings of FIG. 1 to 3 serves as a grab link, which is connected to the O-ring 2 (Fig. 4) into the link circuit of the chain 3 for the protection of the rubber and / or for protection against sliding of rubber.

Mostični člen 1 ima ploščato telo 4 z najmanj eno, prednostno dvema priključnima odprtinama 5 in 6 za verižna člena 2 verige 3 za gumo, torej člena, ki ju nanj obesimo. Nad in pod omenjenima priključnima odprtinama 5, 6 je telo 4 člena odebljeno zasnovano (sl. 2). Pod priključnima odprtinama 5, 6 sta predvideni preko obeh stranskih ploskev 7, 8 štrleči žmuli 9, 10. Nad priključnima odprtinama ima telo 4 člena večjo debelino kot v območju žmul 9, 10. Stranski ploskvi 7, 8 preko ramen 11, 12 zvezno krivinsko prehajata v odseka 13,14 stranskih ploskev, ki potekata v bistvu vzporedno s stranskima ploskvama 7, 8. Kot kaže sl. 3, se telo 4 Člena proti svojima kot del kroga vsakokrat zaokroženima čelnima stranema 15, 16 zoži. V tlorisu po sl. 3 ima telo 4 člena v bistvu rombasto obliko, medtem ko imata njegova vsakokrat le nekako po četrtini dolžine telesa člena raztezajoča se čelna odseka 17, 18 v bistvu trapezno obliko z zaokroženo krajšo osnovnico.The bridge member 1 has a flat body 4 with at least one, preferably two connecting holes 5 and 6 for the chain members 2 of the chain 3 for the rubber, that is, the members that are attached thereto. Above and below the said connection openings 5, 6, the body of the 4 members is boldly designed (Fig. 2). Below the openings 5, 6 are projected through both lateral surfaces 7, 8 projecting beams 9, 10. Above the connection openings, the body 4 has a thickness greater than in the area of the beads 9, 10. The lateral surfaces 7, 8 over the shoulder 11, 12 are continuous curved they extend into sections 13.14 of the lateral surfaces, extending substantially parallel to the lateral surfaces 7, 8. As shown in FIG. 3, the body 4 of the Articles narrows towards each other as a part of the circle, each rounded front sides 15, 16. In the plan of FIG. 3, the body of the 4 members is essentially a diamond shaped shape, while each of them, only about a quarter of the length of the body of the member, extends the front sections 17, 18 in a substantially trapezoidal shape with a rounded shorter base.

Vzdolžni rob 19 telesa 4 člena, t.j. rob, ki prehaja v žmuli 9,10, pri nameščeni verigi 3 za gumo nalega na slednjo, medtem ko je drugi, strehasto zasnovani vzdolžni rob obrnjen k vozišču in tvori obrabno stran 20.The longitudinal edge 19 of the body of 4 members, i.e. the edge passing in the bead 9,10 with the rubber chain 3 resting against the latter, while the other, roof-shaped longitudinal edge faces the carriageway and forms a wear side 20.

1. Op. prev.: Skice so bile izdelane na Nemškem. Zgolj zaradi ekonomičnosti prijavnega postopka pred Uradom so v skicah obdržane (neslovenske) oznake Fig. s pomenom Sl., ne da bi s tem želeli prijavo kakor koli prejudicirati.1. Op. : Sketches were made in Germany. For the sake of economy of the application procedure before the Office, the (non-Slovenian) markings of Figs. with the meaning of Fig. without wishing to prejudice the application in any way.

Nad to obrabno stran 20 štrli profilni del 21, kije zasnovan brez prekinitev in v enem kosu s telesom 4 člena.Above this wear side 20 protrudes a profile portion 21, which is designed without interruption and in one piece with a body of 4 members.

Profilni del 21 je prednostno V mostič oz. rebro, kije predvideno simetrično glede na ravnino Q prečne sredine telesa 4 člena (sl. 3).The profile part 21 is preferably V bridge or. a rib projected symmetrically with respect to the plane Q of the transverse midline of the body of the 4 member (Fig. 3).

Profilni del 21 ima v bistvu kvadratni presek. Njegova kraka 22, 23 se, gledano v tlorisu mostičnega člena (sl. 3), raztezata od srede stranske ploskve 14 telesa člena v nasprotno si usmerjeni smeri poševno na ven tja do nasproti ležeče stranske ploskve 13 oz. do pripadajočih odsekov 24, 25 zoženih odsekov 17,18 telesa člena.The profile part 21 has a substantially square cross section. Its arms 22, 23 extend from the center of the lateral surface 14 of the body of the member in the opposite direction, obliquely outward to the opposite lateral surface 13, respectively. to the corresponding sections 24, 25 of the tapered sections 17.18 of the body of the member.

Kraka 22, 23 medsebojno oklepata kot velikosti okoli 90°. Njuni čelni ploskvi 26, 27 ležita poravnano s stransko ploskvijo 13 in se raztezata nekako do polovice dolžine stranskih odsekov 17, 18. Profilni del 21 ima prisekan vrh 31 z ravno zunanjo ploskvijo 28, ki poteka pravokotno na ravnino Q prečne sredine telesa člena. Omenjena ravnina leži v ravnini stranske ploskve 14 telesa 4 člena.The arms 22, 23 enclose one another with dimensions of about 90 °. Their face planes 26, 27 lie aligned with the lateral face 13 and extend approximately halfway along the length of the side sections 17, 18. The profile portion 21 has a truncated tip 31 with a flat outer face 28 extending perpendicularly to the plane Q of the transverse mid-body of the member. Said plane lies in the plane of the lateral surface 14 of the body of the 4 member.

Debelina profilnega dela 21 je v bistvu enaka debelini telesa člena v območju med priključnima odprtinama 5, 6 oz. čelnima stranema 15,16.The thickness of the profile part 21 is substantially equal to the thickness of the body of the member in the area between the connection openings 5, 6 and. 15.16.

Kraka 22, 23 potekata pod kotom velikosti okoli 45° glede na ravnino L vzdolžne sredine telesa 4 člena. Višina profilnega dela 21 je v bistvu enaka višini odsekov telesa člena pod oz. nad priključnima odprtinama 5, 6. Temenska stran 29 (sl. 1) profilnega dela 21 je izvedena ravno in gladko, tako da se v njej ne morejo fiksirati nikakršni kamni, umazanija ali pd. Temenska stran 29 je, kot kaže sl. 2, prečno na vzdolžno smer mostičnega člena strehasto zasnovana.The arms 22, 23 extend at an angle of magnitude about 45 ° with respect to the plane L of the median body of the member 4. The height of the profile part 21 is essentially equal to the height of the body sections of the member below or. above the connection openings 5, 6. The top side 29 (Fig. 1) of the profile part 21 is made straight and smooth so that no stones, dirt or pd can be fixed in it. The top page 29 is as shown in FIG. 2, transversely to the longitudinal direction of the bridge member roof-shaped.

V verigi 3 za gumo (po sl. 4) O členi in mostični členi 2 in 1 tvorijo pravokotne verižne pentlje 30. Pri verižnih pentljah 30, ki ležijo v vzdolžni smeri Z in sosedno prečno nanjo, so mostični členi 1 tako razporejeni, da kraki 22, 23 njihovih profilnih delov 21 ležijo v vzdolžni smeri Z verige in prečno nanjo, medtem ko so mostični členi sami razporejeni pošev glede na vzdolžno smer verige. V izvedbenem primeru ležijo mostični členi 1 pod kotom velikosti nekako 45° glede na vzdolžno smer Z verige, tako da kraki 22, 23 mostičnih členov potekajo pravokotno na vzdolžno smer verige in vzporedno z njo. Kraki 22, 23 mostičnih členov 1, ki omejujejo določeno verižno pentljo 30, sami kot taki omejujejo kvadrat 30’, katerega diagonali ležita pravokotno na diagonali kvadratnih verižnih pentelj 30 (sl. 4). Tako dodatno h kvadratnim verižnim pentljam 30 vsakokrat obstaja še glede le-teh za 45° zamaknjeno ležeč trakcijski romb 30’, ki ga tvorijo profilni deli 21 mostičnih členov 1 vsakokratne verižne pentlje 30 (sl. 4). Ker imajo profilni deli 21 vsakokrat dva grabilna V robova 32, 33 (sl. 3 in 4) in so mostični členi 1 na prehodu od odsekov 13, 14 stranskih ploskev k vzdolžnemu robu 20 prav tako opremljeni z grabilnima robovoma 34, 35, ima veriga dvakrat toliko grabilnih robov kot veriga, pri kateri mostični členi nimajo pošev glede na njihovo vzdolžno smer ležečih profilnih delov. To, veliko, število grabilnih robov 32 do 35 pride koristno do izraza predvsem pri delu v mehkih tleh.In the rubber chain 3 (according to FIG. 4), the links and bridge members 2 and 1 form rectangular chain loops 30. For chain loops 30 lying longitudinally Z and adjacent transverse to them, the bridge members 1 are arranged so that the arms 22, 23 of their profile members 21 lie in the longitudinal direction Z of the chain and transverse thereto, while the bridge members themselves are arranged obliquely with respect to the longitudinal direction of the chain. In the embodiment, the bridge members 1 lie at an angle of magnitude 45 ° with respect to the longitudinal direction Z of the chain, so that the arms 22, 23 of the bridge members extend perpendicularly to and along the longitudinal direction of the chain. The legs 22, 23 of the bridge members 1, which restrict a particular chain loop 30, themselves as such limit the square 30 ', the diagonals of which are perpendicular to the diagonal of the square chain loop 30 (Fig. 4). Thus, in addition to the square chain loops 30, there is always a 45 ° offset traction rhombus 30 'formed by the profile sections 21 of the bridge members 1 of each chain loop 30 (Fig. 4). Since the profile sections 21 each have two rake V edges 32, 33 (Figures 3 and 4) and the bridge members 1 are also provided with grab rails 34, 35 at the passage from sections 13, 14 of the lateral surfaces to the longitudinal edge 20. twice as many grab edges as a chain where the link members do not have slopes relative to their longitudinal direction of the profile sections. This, large, number of rake edges 32 to 35 comes in handy especially when working in soft soils.

Veriga ima lahko tudi druge konfiguracije. Tako denimo so verižne pentlje lahko zasnovane kot satje. V tem primeru imajo verižne pentlje obliko šestkotnika. Grabilna robova 32, 33 profilnih delov 21 in grabilna robova 34, 35 mostičnih členov skupaj prav tako pomenijo veliko število robov za dosego grabljivosti, ki so dobrodošli zlasti v mehki podlagi.The chain may also have other configurations. For example, chain loops can be designed as honeycombs. In this case, the chain loops have the shape of a hexagon. The grab edges 32, 33 of the profile sections 21 and the grab edges 34, 35 of the bridge members together also represent a large number of edges to achieve predation, which are especially welcome on a soft base.

Profilni deli 21 mostičnih členov imajo to prednost, da imajo po zaslugi svoje neprekinjene zasnove kot kotnik največjo možno trakcijsko in obstojnostno trdnost, saj se pri ekstremni obremenitvi ne morejo odlomiti nikakršni posamezni odseki profilnih delov. Velikoploskovna in gladka zasnova profilnih delov zagotavlja visoko samočiščenje verige. Z grabilnimi robovi profilnih delov se na enostaven način doseže posebno dobra grabljivost in ohranjanje smeri. S tem postane veriga za gume z mostičnimi členi po sl. 1 do 3 posebno primerna za mehka tla, v katerih zagotavlja dober prenos moči in visoko ohranjanje smeri. Po zaslugi V zasnove profilnih delov 21 je za kaljenje profilnih delov na voljo velika površina, tako da se profilni deli glede na namen uporabe verige 3 lahko optimalno kalijo.The profile sections of the 21 bridge members have the advantage of having the highest possible traction and stability due to their continuous design as an angle, since no individual sections of profile sections can be broken under extreme load. The large and smooth design of the profile parts ensures high self-cleaning of the chain. The gripping edges of the profile sections make it particularly easy to achieve particularly good grip and maintain direction. Thereby, it becomes a tire chain with a bridge link according to FIG. 1 to 3 especially suitable for soft floors in which it provides good power transfer and high directional maintenance. Due to the design of profile parts 21, a large surface area is available to harden the profile parts so that the profile parts can be optimally germinated according to the purpose of using the chain 3.

Profilni deli 21 mostičnih členov 1 so lahko za nadaljnje povečanje grabljivosti in kalilnih območij opremljeni z dodatnimi štrlinami oz. glaviči in/ali bočnimi poglobitvami, kakršni so znani pri vsakdanjih mostičnih členih. S tem se da nuditi ustrezno verigo za posebne razmere uporabe. Mostični členi 1 so lahko v sklopu verige tako razporejeni, da kraki 22, 23 profilnih delov 21 niso usmerjeni v smeri verižne pentlje, ki jo omejujejo mostični členi, ampak so usmerjeni na ven. Mostični členi 1 so tudi lahko tako razporejeni, da so kraki 22, 23 enega dela mostičnih členov usmerjeni na ven in kraki drugih mostičnih členov na noter. Na ta način se dajo grabilne razmere in ohranjanje smeri verige individualno prilagajati vsakokrat želenemu namenu uporabe. V izvedbenem primeru so mostični členi opremljeni vsakokrat le z enim kotThe profile sections of the 21 bridge members 1 can be fitted with additional projections or extensions to further increase the predation and germination areas. combs and / or lateral recesses as is known in everyday bridge articulations. This makes it possible to provide a suitable chain for the specific conditions of use. The bridge members 1 may be so arranged in the chain assembly that the arms 22, 23 of the profile sections 21 are not directed in the direction of the chain hinge bounded by the bridge members, but are directed outwards. The bridge members 1 may also be so arranged that the arms 22, 23 of one part of the bridge members are directed outwards and the arms of the other bridge members inwards. In this way, the rake conditions and preservation of the chain direction can be individually adjusted to the intended purpose of use. In the embodiment, the bridge members are provided with only one angle each

V oblikovanim profilnim delom 21. Povsem je možno, daje mostični člen opremljen tudi z vsaj enim nadaljnjim kot V oblikovanim profilnim delom. Tudi se lahko na krake 22 ali 23 veže nadaljnji, kotno nanje ležeč krak. Ta lahko leži vzporedno h kraku 23 in 22, lahko pa se razteza tudi pod kotom glede slednjega.In molded profile section 21. It is entirely possible that the bridge link is also provided with at least one further than V shaped section. A further, angled arm may also be attached to arms 22 or 23. It may lie parallel to the arms 23 and 22, but may extend at an angle to the latter.
