SI9010544A - Arrangement for joining the edges of flat elements - Google Patents

Abstract

For joining the edges (33, 37) of two flat elements (31, 35) which lie approximately in parallel along a common section, the common edge has at least one grabbing element (39) whose shape in the direction of edges accurately meshes with the cutout (43) on the edge (37). At least one protrusion (47, 49) on the edge (33), which is with respect to the grabbing element disaligned on both sides in the direction of meshing, leans in the direction of edges accurately against the element (35) with a cutout. In an analogue way, for joining the contacting edges (33, 37) of the open ends of a ring-shaped belt, a grabbing tongue (39) is positioned preferably in the centre of the edge (33) with two clips (40, 41) protruding on both sides of the tongue. The tongue accurately meshes with the cutout (43) with an approximately the same overlapping surface and is placed approximately in the middle of the other edge (37). On the edge (33) on each side of the tongue (39) is positioned a protrusion (47, 49), preferably on each end of the edge. In the direction of the edge towards the cutout each of these protrusions mesh accurately with the shape of the belt element (35) with the cutout (43).

Priprava za spajanje dveh robov ploskih delovPreparation for joining two edges of flat parts

Izum obsega pripravo za spajanje po uvodnem delu 1. patentnega zahtevka, s spono po uvodnem delu 8. patentnega zahtevka, s cevno spono ali prižemnim obročem s pripravo po uvodnem delu 11. patentnega zahtevka, z uporabo priprave kot tudi s pripravo za povezavo valjastega dela ali cevi z vsaj še enim cevnim elementom ali prevleko.The invention encompasses a coupling device according to the introductory part of claim 1, with a clamp according to the introductory part of claim 8, with a pipe clamp or a clamping ring with the preparation according to the introductory part of claim 11, using the device as well as the device for connecting the cylindrical part or pipes with at least one other pipe element or coating.

Za trdno spajanje cevnih elementov na ustreznem robnem območju valjastega dela, kot npr. osi ali daljše cevi, se uporablja znane vrste in načine t.i. spojnih obročev.For rigid joining of pipe elements in the corresponding edge region of the cylindrical part, such as e.g. axes or longer tubes, known types and modes, e.g. connecting rings.

Uporaba spojnih obročev s t.i. ušesi je v praksi dokazano v mnogo primerih neprimerna. Zlasti npr. tedaj, ko prostor ne dovoljuje štrlečih ušes.The use of connecting rings with i.e. ears are proven in many cases inappropriate in practice. In particular e.g. when space does not allow protruding ears.

V teh primerih so se izkazali t.i. sponski ali pritezni obroči, ki se jih za trden prijem bodisi zunaj namesti ali natisne ali pa se z razširitvijo valjastega dela obe cevi natisne druga na drugo.In these cases, t.i. clamping or clamping rings which are either mounted or printed out for a firm grip or by extending the cylindrical part, both tubes are printed on top of each other.

Take spone ali pritezni obroči so izdelani tako, da se iz cevi ustreznega premera izseka obročaste segmente. Takšen način izdelave pa ima pomanjkljivosti, ker:Such clamps or clamping rings shall be constructed in such a way as to cut out annular segments from a pipe of the proper diameter. However, this method of manufacture has disadvantages because:

a) je potrebno novo izdelane cevi na njihovih koncih očistiti opilkov, kar zahteva dodatno ročno delo,a) the newly made pipes at their ends need to be cleaned with trim, which requires additional manual work,

b) se lahko uporabi le neijavne materiale, nikakor pa ne npr. pocinkane cevi, ker so obroči na vzdolžnih koncih poškodovani, tj. tam ni cinka,b) only non-glossy materials may be used and not e.g. galvanized pipes because the rings at the longitudinal ends are damaged, ie. there is no zinc,

c) z enim premerom cevi se lahko izdela samo eno velikost obročev.c) Only one ring size can be made with one pipe diameter.

Nadaljnja možnost obstoji v nabijanju t.i. podložnih ploščic, pri čemer je za to operacijo potrebno porabiti več energije, s čimer se v obročastem delu ustvarja velike notranje napetosti. Prav tako se z določeno velikostjo podložne ploščice ne da izdelati obročev različnih premerov.A further possibility exists in the compaction of i. washers, which requires more energy to be used for this operation, thus generating large internal stresses in the annular portion. Also, rings of different diameters cannot be made with a given size of the washer.

Nadaljnja možnost obstoji v izdelavi obroča iz ustreznega tračnega dela, ki se ga izseka iz neskončnega traku in nato zvije v obliko obroča. Pri tem se je pokazalo, da spoj obeh koncev traku predstavlja slabo točko in da ta vez ne prenaša obremenitve na nateg in tlak.A further possibility exists in the manufacture of a ring from a suitable band part, which is cut from an endless strip and then rolled into the shape of a ring. In doing so, it has been shown that the joint of the two ends of the strap represents a weak point and that this bond does not withstand tensile and pressure loads.

Naloga izuma je zato ustvariti posebno pripravo za spajanje skrajnih robov traku za izdelavo obroča in na pripravo za spajanje dveh robov v splošnem, ki se jo da obremeniti na nateg in tlak.The object of the invention is therefore to create a special device for joining the extreme edges of the strap for making a ring and for a device for joining two edges in general, which can be applied to tension and pressure.

Po izumu je to rešeno s pripravo za spajanje, prednostno po vsaj enem patentnem zahtevku, zlasti po 1. zahtevku, kot tudi s postopkom, prednostno po vsaj enem patentnem zahtevku, zlasti 11. zahtevku.According to the invention, this is solved by a coupling device, preferably according to at least one claim, in particular according to claim 1, as well as by a process, preferably according to at least one claim, in particular claim 11.

Predlaga se pripravo za spoj dveh robov ploskih delov, ki potekata medsebojno približno vzporedno vsaj vzdolž enega skupnega odseka, pri čemer priprava obsega na enem robu vsaj eden zgrabilni element, ki se prilega ustreznemu izrezu na drugem robu zaradi prijema v smeri roba, in nadalje obsega vsaj eno štrlino na enem robu, ki je bočno premaknjena glede na element, in ki nalega na del z izrezom približno v smeri roba natančno po obliki.It is proposed to have a device for joining two edges of planar parts extending approximately parallel to one another at least along one common section, the device comprising at least one grab element at one edge, which fits into the corresponding notch at the other edge for receiving in the direction of the edge, and further comprises at least one projection on one edge, which is laterally displaced relative to the element, and which rests on a portion with a cutout approximately in the direction of the edge exactly in shape.

Pri nadaljnji izvedbi se predlaga, da zgrabilni element prijemlje v izrez z obeh strani v smeri robov in da je, temu ustrezno, na obeh straneh elementa na robu razporejena po ena bočno prestavljena štrlina, ki na del z izrezom nalega natančno po obliki v smeri elementa.In a further embodiment, it is proposed that the grab element engages in a cutout on both sides in the direction of the edges and that, accordingly, one laterally projected projection is arranged on both sides of the edge piece, which fits exactly in the shape with the cutout in the direction of the element .

Zlasti v primeru spoja dveh robov vzdolž sorazmerno kratkega skupnega odseka se predlaga, da zgrabilni element prijemlje izrez približno v sredini skupnega odseka in da je štrlina ali so štrline približno razporejena(e) v območju(ih) enega (obeh) koncev.In particular, in the case of a joint of two edges along a relatively short common section, it is suggested that the grab element grips the cutout approximately in the middle of the common section and that the projection or projections are approximately spaced in the area (s) of one (both) ends.

Za pripravo za spajanje dveh trakastih, vzdolžno potekajočih delov s prečno na potek traku razporejenimi priključnimi robovi, pri čemer so širine trakov delov vsaj v območju priključnih robov prednostno skoraj enake, se predlaga zgrabilni element na enem robu, ki v smeri roba prijemlje v izrez, razporejen na drugem robu, kateri izrez ima glede na element približno enako prekrivno površino in vsaj eno štrlino na robu, ki je bočno premaknjena glede na smer prijema elementa in ki na del z izrezom nalega natančno po obliki v smeri k elementu.In order to prepare for joining two striped, longitudinally extending portions with connecting edges arranged transversely to the ribbon, with the widths of the ribbons of the portions being preferably almost identical in the region of the connecting edges, preferably, a grab element is provided on one edge, which in the direction of the edge engages in the recess, arranged on the other edge, the cutout having about the element having approximately the same overlapping surface and at least one projection on the edge, which is laterally displaced with respect to the receiving direction of the element, and which fits exactly with the cutout in the direction of the element.

Pri enem od izvedbenih primerov se predlaga zgrabilni jezik, ki je razporejen približno v sredini roba, s po eno izpostavljeno spojko z obeh strani jezika, ki sta približno vzporedni s smerjo roba, pri čemer jezik prijemlje natančno po obliki v izrez, razporejen na drugem robu, ki ima približno enako prekrivno površino in je tudi razporejen približno v sredini, pri čemer je nadalje z obeh strani jezika na robu, prednostno na koncu roba, razporejena po ena bočno zamaknjena štrlina, pri čemer vsaka štrlina nalega natančno po obliki na trakasti del z izrezom, ki je približno vzporeden s smetjo roba, vsaka v smeri proti izrezu.In one embodiment, a grab tongue disposed approximately in the middle of the edge is proposed, with one exposed clutch on each side of the tongue, approximately parallel to the direction of the edge, with the tongue gripping precisely in the shape of the recess arranged on the other edge. , which has approximately the same overlapping surface and is also arranged approximately in the middle, further along each side of the tongue, preferably at the end of the edge, one laterally offset projection, with each projection lying exactly in shape on a strip portion with a cutout approximately parallel to the debris edge, each in the direction of the cutout.

S pomočjo tega izvedbenega primera je mogoča povezava sorazmerno ozkih trakastih delov vzdolž priključnih robov le-teh.With the aid of this embodiment, it is possible to connect relatively narrow strip parts along the connecting edges thereof.

Če so deli, ki se spajajo vzdolž skupnega odseka, plošče, ima spojka prednostno vsaj dva zgrabilna elementa na enem robu, pri čemer je po eden zgrabilni element razporejen v vsaki polovici skupnega odseka. Analogno zgoraj navedenemu prijemljeta vsaj dva zgrabilna elementa natančno po obliki v ustrezna izreza na drugem robu, pri čemer je na robu razporejena, bočno zamaknjeno k zunanjosti elementa in v smeri konca skupnega odseka, vsaj po ena štrlina, ki natančno po obliki nalega na del z izrezom približno v smeri robov proti zunanjemu izrezu.If the parts joining along the joint section are panels, the coupling preferably has at least two grab elements on one edge, with one grab element arranged in each half of the joint section. Similarly to the above, at least two grab elements are accurately shaped in the corresponding cutouts on the other edge, at the edge being arranged, laterally offset to the outside of the element and towards the end of the common section, at least one projection, which exactly fits in part with cutout approximately in the direction of the edges toward the outer cutout.

Zaradi trdne pritrditve zgoraj opisane spojke po izumu se nadalje predlaga, da se določi vsaj eno mesto za vtiskovanje, sploščenje in/ali točkasto varjenje vzdolž skupnega odseka robov zgrabilnega elementa in/ali štrlin.Due to the rigid attachment of the joint described above according to the invention, it is further proposed to designate at least one spot for embossing, flattening and / or spot welding along the joint section of the edges of the grab element and / or projections.

Omenjene priprave za spajanje po izumu so zlasti primerne za izdelavo spenjal, ki sestoje iz vsaj enega ozkega spenjalnega traku s priključnimi robovi, razporejenimi na njegovem koncu prečno glede na smer traku.Said coupling devices according to the invention are particularly suitable for the manufacture of fasteners consisting of at least one narrow clamping strap with connecting edges arranged at its end transversely with respect to the direction of the strap.

Takšno spenjalo tvori enodelen spenjalni trak, pri čemer sta oba priključna robova spaja s pripravo za spajanje po izumu.Such a clamp forms a one-piece clamping strap, the two connecting edges joining with the coupling device of the invention.

Takšno spenjalo je zlasti primemo za izdelavo cevnih spon ali prižemnega obroča.Such a clamp is particularly suitable for making pipe clamps or a clamping ring.

Nadalje se predlaga pripravo za spajanje dveh robov obročastih delov, ki vsaj vzdolž skupnega odseka potekata približno medsebojno vzporedno.It is further proposed to prepare for joining the two edges of the annular portions, which extend at least along a common section approximately parallel to each other.

Po tej pripravi se na robu predvideva vsaj eden zgrabilni element, ki se ga vodi v ustrezen izrez na drugem robu in prijemlje natančno po obliki, da se prepreči izvlečenje elementa iz izreza in s tem zadrži dele drugega polg drugega. Da se prepreči bočno odpiranje odsekov v prijemu na delu z izrezom v smeri prijema, je na robu razporejena vsaj ena štrlina, premaknjena bočno glede na element v smeri prijema, ki na del z izrezom približno v smeri robov nalega natančno po obliki tako, da deluje nasprotno od rezultirajoče, približno od izreza v smeri robov delujoče komponente sile, ki nastaja zaradi prijema izreza z elementom pri obremenitvi spoja na nateg in/ali tlak. S tem se popolnoma prepreči odpiranje omenjenih odsekov v prijemu.After this preparation, at least one grab element is provided at the edge, which is guided to the corresponding notch on the other edge and grips precisely in shape to prevent the element from being pulled out of the notch and thereby retaining parts of the second lever of the other. In order to prevent lateral opening of the sections in the grip portion with the notch in the receiving direction, at least one projection disposed laterally with respect to the element in the grip direction is disposed on the edge, which fits precisely in the direction of the edges exactly in the shape so that it acts the opposite of the resultant, approximately, cut-out in the direction of the edges of the acting component of the force generated by the engagement of the cut-out with the element when the joint is tensile and / or pressured. This completely prevents the opening of said sections in the grip.

Po prednostni pripravi za spajanje dveh trakastih, vzdolžno potekajočih delov vzdolž priključnih robov, razporejenih približno prečno glede na smer traku, pri čemer so širine traku telesa vsaj v območju priključnih robov približno enake, se predlaga, daje zgrabilni jezik namesti približno v sredino roba, pri čemer ima jezik z obeh strani, vzporedno s smerjo robov, po eno izstopajočo spojko, in da se jezik namesti in prijemlje natančno po obliki v izrez na drugem robu, kateri izrez ima približno enako prekrivno površino in je prav tako razporejen v sredini. Z obeh strani jezika je na robu razporejena po ena bočno zamaknjena štrlina, ki je vzporedna s smerjo robov in na del z izrezom nalega natančno po obliki v smeri izreza. S tema štrlinama se deluje na nasproti smeri odpiranja, bočno od jezika razporejena odseka trakastega dela z izrezom, s čimer se tako zasnovano spojko lahko obremeni na nateg in tlak.Following a preferred arrangement for joining two striped, longitudinally extending portions along the connecting edges, arranged approximately transversely with respect to the direction of the strip, the width of the body strap being approximately the same in the region of the connecting edges, it is proposed to place the grab tongue approximately at the center of the edge, at the tongue having on one side, parallel to the direction of the edges, one projecting joint, and the tongue being positioned and gripped precisely in a cutout on the other edge, the cutout having about the same overlapping surface and also arranged in the middle. On the edges of the tongue, there is a laterally displaced projection on the edge, which is parallel to the direction of the edges and fits precisely in the direction of the cutout with the cutout. These projections act in the opposite direction of the opening of the section of the ribbon-shaped section with a cut-out laterally from the tongue, which can put the coupling designed in this way to tension and pressure.

Z namenom dodatne utrditve ali fiksiranja spojke se robove na vsaj enem mestu skupnega odseka, zgrabilnega jezika in/ali štrline vtisne, plosko združi ali točkovno zvari.In order to further consolidate or secure the coupling, the edges of the at least one location of the joint section, the grab tongue and / or the projection are impressed, flattened or welded spotwise.

Omenjene priprave po izumu so zlasti primerne za spajanje enega ali več trakastih teles za izdelavo steg ali prižemnega obroča.Said devices according to the invention are particularly suitable for joining one or more strip bodies for making thighs or a clamping ring.

V primeru tako izdelanega prižemnega ali pritisnega obroča se predlaga pripravo za spajanje valjastega dela ali cevi z vsaj še enim cevnim elementom ali prevleko, na katero pripravo se drugo cev ali prevleko potegne prek obrobnega območja prvega valjastega dela ali cevi, s čimer se stego ali pritisni obroč po izumu namesti preko druge cevi ali prevleke na navlečeno območje. Končno se bodisi prižemni obroč s primernim orodjem stisne ali natisne, ali pa se valjasti del ali cev na obrobnem območju razširi radialno k zunanjosti.In the case of a clamping or pressing ring thus constructed, a device is proposed for joining a cylindrical part or tube with at least one other tube element or cover, to which a device is pulled by a second tube or cover over the peripheral region of the first cylindrical part or tube, thereby tightening or pressing the ring according to the invention is mounted over another pipe or cover to the coated area. Finally, either the clamping ring is pressed or printed with a suitable tool, or the cylindrical part or tube extends radially to the outside in the peripheral region.

Izum je s sklicevanjem na priložene skice pobliže obrazložen s pomočjo primerov. Pri tem kaže sl. 1 pripravo za spajanje dveh trakastih elementov - ploščatih delov po izumu, sl. 2 nadaljnjo izvedbo spojke po izumu, sl. 3 še nadaljnjo izvedbo spojke po izumu, sl. 4 spoj po izumu dveh delov z veliko površino vzdolž ožjih vzdolžnih robov, sl. 5 spojko po izumu, predvideno z mesti za vtiskovanje, sl. 6 stego ali prižemni obroč po izumu v nespojenem, odprtem stanju, sl. 7 spoj osi z obložno cevjo z uporabo stege oz. prižemnega obroča.The invention will be more fully explained by way of examples by reference to the accompanying drawings. In this respect, FIG. 1 is an apparatus for joining two strip elements - the flat parts according to the invention; 2 shows a further embodiment of the coupling according to the invention; 3 shows a further embodiment of the coupling according to the invention; 4 shows a joint according to the invention of two large-area sections along narrower longitudinal edges; FIG. 5 shows the coupling according to the invention provided with the embossing points; FIG. 6 shows a clamp or clamping ring according to the invention in an unconnected, open state, FIG. 7 joints the axes with the hose using a clamp or. of the clamping ring.

Na sl. 1 do 3 so prikazane različne možne variante izvedb spojke po izumu. Spojke so prikazane v pogledu od zgoraj na ploske dele oz. od zgoraj pravokotno na priključne robove, ki jih je potrebno spojiti.In FIG. 1 to 3 illustrate various possible embodiments of the coupling according to the invention. The couplings are shown in the top view of the flat parts or. from above perpendicular to the connecting edges to be joined.

Ploska dela 1 in 5 sta medsebojno spojena vzdolž svojih skupnih robov 3 oz. 7. Ta ploska dela 1 in 5 sta lahko plošči, trakasta dela, sorazmerno tanki palici in podobno. Na robu 3 je predviden zgrabilni element ali zgrabilni jezik 9, ki obsega bočno štrleče vezne elemente. Po sl. 1 in 2 obsega jezik 9 dve tanki spojki 10 in 11, medtem ko je na sl. 3 razporejena ena sama štrleča spojka 11. Jezike 9 se namesti v ustrezne izreze 13 v delu 5 z enako prekrivno površino. Jezik 9 prijemlje v izrez 13 s pomočjo obeh spojk 10 in 11 vzdolž obseh odsekov 14 in 15 dela 5, ki potekata v smeri robov delov.The flat parts 1 and 5 are interconnected along their common edges 3 and. 7. These flat parts 1 and 5 may be panels, striped parts, relatively thin bars and the like. A grab element or a grab tongue 9 comprising laterally projecting attachment members is provided at the edge 3. According to FIG. 1 and 2 comprise tongue 9 with two thin joints 10 and 11, while in FIG. 3 a single projection 11 is arranged. The tongues 9 are positioned in the corresponding recesses 13 in part 5 with the same overlapping surface. The tongue 9 grips into the recess 13 by means of both couplings 10 and 11 along the circumference of sections 14 and 15 of part 5 extending in the direction of the edges of the parts.

Kadar se spojko po sl. 1 in 2 obremeni na nateg ali tlak, obstaja težnja področij ploskega dela 5, postavljenih izza odsekov 14 in 15, da se premaknejo bočno od jezika 9, zaradi česar bi jezik 9 lahko izskočil ali se izvlekel iz izreza 13. Da bi se to težnjo k bočnemu premiku onemogočilo, sta na robu 3 razporejeni štrlini 17 in 19. Obe štrlini 17 in 19 nalegata na odseka 18 in 20 ploskega dela 5, š čimer delujeta proti bočnemu premiku območja izza odsekov 18 in 20 oz. odsekov 14 in 15. S takšno razporeditvijo obeh štrlin 17 in 19 je spoj ploskih delov 1 in 5 vzdolž robov 3 in 7 popolnoma utrjen proti nategu ali tlaku. Štrlini 17 in 19 sta lahko razporejeni tako na koncu roba 3 kot tudi med jezikom 9 in koncem roba 3.When the coupling of FIG. 1 and 2 load on tension or pressure, there is a tendency for the areas of the flat part 5, positioned behind sections 14 and 15, to move laterally from the tongue 9, causing the tongue 9 to pop out or to be pulled out from the recess 13. to the lateral displacement, projections 17 and 19 are disposed on the edge 3. Both projections 17 and 19 lie on the sections 18 and 20 of the flat part 5, thus acting against the lateral displacement of the area beyond the sections 18 and 20 and respectively. sections 14 and 15. With this arrangement of the two projections 17 and 19, the joint of the flat parts 1 and 5 along the edges 3 and 7 is fully cured against tension or pressure. The projections 17 and 19 may be disposed at the end of edge 3 as well as between tongue 9 and end of edge 3.

Na sl. 3 jezik 9 obsega samo eno spojko 11, ki prime v ustrezen izrez vzdolž odseka 14. Pri tem izvedbenem primeru je seveda potrebna le en sama štrlina 19, ki nalega vzdolž odseka 20 ploskega dela 5. Ta štrlina 19 je prav tako namenjena preprečitvi bočnega premika območij dela 5 izza odsekov 14 in 20.In FIG. 3, the tongue 9 comprises only one coupling 11 which fits into the corresponding cutout along the section 14. In this embodiment, of course, only one projection 19 is required, which fits along the section 20 of the flat part 5. This projection 19 is also intended to prevent lateral movement areas of section 5 behind sections 14 and 20.

Na sl. 4 je prikana spoj dveh plošč 1 in 5 vzdolž skupnega roba 3, 7, pri čemer ima rob 3 v tem primeru dva zgrabilna elementa ali jezika 29, ki se ju namesti v ustrezna izreza 23. Pri izvedbenem primeru spojke po izumu, prikazanem na sl. 4, med jezikoma 29 niso predvideni prisloni, ker jezika 29 delujeta protismerno proti bočnemu premiku območja dela 5, ki leži med njima. Na obeh koncih roba 3 je razporejena po ena štrlina 17 in 19, ki nalega na odsek 18 oz. 20 dela 5.In FIG. 4 is a hooked joint of two plates 1 and 5 along a common edge 3, 7, wherein the edge 3 in this case has two grab elements or tongues 29, which are installed in the corresponding recess 23. In the embodiment of the coupling according to the invention shown in FIG. . 4, no backrests are provided between the tongues 29 because the tongues 29 act in a counter-direction to the lateral displacement of the area of the portion 5 lying between them. At each end of edge 3, one projection 17 and 19 are disposed, which is adjacent to section 18 and. 20 Part 5.

Za pritrditev zgoraj opisanega spoja dveh ploskih teles 1 in 5 se predlaga, da se določi t.i. mesta za ploskovno spajanje ali mesta za vtiskovanje. Na sl. 5 je v osnovi prikazan izvedbeni primer po sl. 1, pri čemer sta vzdolž jezika 9 predvideni dve mesti 24 za vtiskovanje in vzdolž roba 3 še dve mesti 25 za vtiskovanje. S tem vtiskovanjem trakasta dela 1 in 5 nista več medsebojno fiksno spojena, temveč obstaja z možnostjo razdvajanja.In order to secure the joint of the above-described joint of the two planar bodies 1 and 5, it is proposed to determine e.g. planar joining or embossing sites. In FIG. 5 is a basic embodiment of FIG. 1, two two embossing points 24 are provided along the tongue 9 and two embossing positions 25 along the edge 3. With this embossing, the strips 1 and 5 are no longer fixedly interconnected, but exist with the possibility of separation.

Na mestu vtiskovanja ali mesta za ploskovno spajanje gre lahko tudi za mesto spajkanja, v vsakem primeru prednostno samo tedaj, kadar sta dela 1 in 5 iz nerjavnega materiala.The embossing or planar joining site may also be a soldering point, in each case preferably only if the parts 1 and 5 are made of stainless material.

Na sl. 6 je prikazana stega ali prižemni obroč po izumu, ki sestoji iz prižemnega traku z dvema koncema 31 in 35. Prižemni obroč je prikazan v nespojenem, odprtem stanju. Prižemni trak je lahko enodelen ali večdelen, z ustrezno eno ali več spojkami.In FIG. 6 shows a clamp or clamping ring according to the invention consisting of a clamping strip with two ends 31 and 35. The clamping ring is shown in an unconnected, open state. The clamping strap may be one-piece or multi-piece, with corresponding one or more joints.

Priključna robova 33 in 37 na konceh 31 in 35 sta na veznih elementih predvidena analogno izvedbenemu primeru po sl. 1. Na robu 3 je razporejen jezik 39 z na obe strani štrlečima veznima deloma 40 in 41. Nadalje sta predvideni štrlini 47 in 49. V ustrezni obliki je na robu 37 zasnovan izrez 43 kot tudi odseka 48 in 50, v ali na katere se namesti ustrezne elemente roba 33.The connecting edges 33 and 37 at the ends 31 and 35 on the connecting elements are provided in analogy to the embodiment of FIG. 1. On the edge 3 there is a tongue 39 arranged on both sides projecting connecting parts 40 and 41. Further projections 47 and 49 are provided. In the appropriate shape, a cutout 43 is formed on the edge 37, as well as sections 48 and 50, in or on which installs appropriate edge elements 33.

Odvisno od želenega premera stege pritisnega obroča se od neskončnega traku da odrezati ustrezen tračni odsek. Na obeh koncih 31 in 35 tega odseka se vzdolž robov 33 in 37 izseka ali iztisne ustrezne elemente.Depending on the desired diameter of the clamp of the pressure ring, a corresponding strip section can be cut from the endless strip. At either ends 31 and 35 of this section, the corresponding elements are cut or extruded along the edges 33 and 37.

S spojitvijo robov 33 in 37 z ustrezno zasnovanima veznima elementoma in upogibanjem tračnega odseka se pri tem dobi prižemni obroč. Zaradi fiksiranja spojke se lahko, kot je prikazano na sl. 5, določi mesta za vtiskovanje ali ploskovno spajanje.Joining the edges 33 and 37 with properly designed connecting elements and bending the ribbon section results in a clamping ring. Due to the coupling fixation, as shown in FIG. 5, identify the embossing or planar joining points.

Na sl. 7 je prikazana stega ali prižemni obroč po izumu, uporabljen v praksi v spojenem, zaprtem stanju.In FIG. 7 illustrates a clamp or clamping ring of the invention used in practice in a coupled, closed state.

Os 80 ima skončni del 82 večjega premera od premera osi. S to osjo je potrebno spojiti obložno cev 84, ki se jo z njenim skončnim delom 86 potegne preko skončnega dela 82 in trdno spoji z osjo 80. Takšen spoj je pogost npr. v avtomobilski industriji, kjer se osi koles, menjalnikov ali kardanskih gredi zaščiti ali obloži z valovito cevjo. Tudi tu se gumijasta ali valovita obloga drži na elementu, npr. na osi.The axis 80 has an end portion 82 larger than the diameter of the axis. With this axis it is necessary to connect the hose 84, which is pulled with its end part 86 over the end part 82 and firmly connected to the axis 80. Such a joint is common e.g. in the automotive industry where the axles of wheels, gearboxes or PTO shafts are secured or coated with a corrugated tube. Here too, a rubber or wavy lining is held on the element, e.g. on the axis.

Potem, ko se je oblogo 84 z njenim skončnim delom 86 potegnilo čez skončni del 82, se tudi prižemni obroč potegne preko skončnega dela 86. Jezik 109 se vstavi v ustrezni izrez 113, bočni štrlini 117 in 119 pa naležeta na odseka 118 in 120 konca 105 traku. S tem sta oba konca traku medsebojno trdno spojena, spoj pa je lahko predviden z mesti za vtiskovanje ali ploskovno spajanje, kot je prikazano na sl. 5.After the lining 84 with its end part 86 is pulled over the end part 82, the clamping ring is also pulled over the end part 86. The tongue 109 is inserted into the corresponding recess 113, and the lateral projections 117 and 119 are adjacent to sections 118 and 120 of the end 105 tape. The two ends of the strip are thus firmly connected to one another, and the joint can be provided with embossing or planar joining points, as shown in FIG. 5.

Po namestitvi prižemnega obroča čez nataknjeno območje 86 se s primernim orodjem (tu neprikazanim), razporejenim okoli prižemnega obroča, in s pritiskanjem čeljusti orodja obroč natisne na območje 86. S to operacijo stiskanja se premer spojnega obroča zmanjša, zaradi česar nastanejo na spojnem obroču natisna območja 91. Sedaj je obloga 84 trdno spojena z osjo 80.After mounting the clamping ring over the inserted area 86, a suitable tool (not shown here) arranged around the clamping ring and pressing the tool caliper presses the area to the area 86. This compression operation reduces the diameter of the connecting ring, resulting in printing on the connecting ring. areas 91. Now lining 84 is firmly joined to axis 80.

Spoj se da ustvariti tudi tako, da se namesto natisnjenja notranje območje 82 razširi k zunanjosti, pri čemer obloge na nataknjenem območju 86 z zunanje strani trdno stisne k notranjemu območju 82. Notranje področje 82 je tedaj seveda iz elastičnega materiala, kot npr. pločevina ali tankostenski material.The joint can also be created by extending the inner region 82 to the outside instead of printing, with the liners in the contact area 86 firmly pressed from the outside to the inner region 82. The inner region 82 is then of course made of an elastic material, such as e.g. sheet metal or thin-walled material.

S pomočjo sl. 7 pojasnjeni postopek se da seveda uporabiti za spajanje x poljubnih kot os zasnovanih in cevastih elementov s pomočjo stege ali prižemnega obroča.By means of FIG. 7, the explained procedure can of course be used to join x arbitrary as axis-shaped and tubular elements by means of a clamp or a clamping ring.

Opisane spoje ploskih delov in koncev trakov v primerih 1 do 7 s te gami in prižemnimi obroči se da menjati na x želenih načinov in vrst. Bočni deli zgrabilnih elementov ali jezikov npr., ki prijemljejo v ustrezne izreze, so lahko zasnovani na x želenih načinov in vrst. Ti deli so lahko npr. z navojem, imajo lahko več spojk ipd. Tudi bočne štrline so lahko zasnovane na več načinov, npr. v obliki trikotnika, z okroglimi jeziki ipd. Tudi uporaba spoja je mnogostranska, vendar je za izum pomembno, daje na vsaj eni strani zgrabilnega elementa razporejena štrlina in to na strani, na kateri zgrabilni element prijemlje v ustrezni izrez.The joints of the flat parts and the ends of the straps in Examples 1 to 7 with these gauges and the clamping rings can be changed in x desired ways and types. The lateral parts of the gripping elements or tongues, for example, which fit into the corresponding cutouts, may be designed in x desired ways and types. These parts may be e.g. threaded, may have more couplings, etc. Also, the side projections can be designed in many ways, e.g. in the form of a triangle, with round tongues, etc. The use of the joint is also versatile, but it is important for the invention that a projection is arranged on at least one side of the grab element and on the side on which the grab element engages in the corresponding cutout.
