Description

Izum se odnosi na profilnu spojnicu prema značajkama navedenim u uvodnom dijelu patentnog zahtjeva 1. The invention relates to a profile connector according to the features listed in the introductory part of patent claim 1.

Iz DE 44 06 208 A1 poznata je takova profilna spojnica s pridržnim čeljustima, koja se može dovesti u zahvat s uzdužnim utorima prvog profila za izradu čvrstog i fiksnog spoja. Pridržne čeljusti nalaze se u svakom slučaju na kraju pridržnih spojnica, koje se nalaze unutar kućišta, koje se sa čeone strane može umetnuti u šuplju komoru drugog profila. Pridržne spojnice su izrađene savinute i imaju zakrivljene vanjske površine koje leže jedna na drugoj, preko kojih se bočno podupiru obje pridržne spojnice. Pridržne spojnice pritežu se međusobno suprotno pomoću vijka tako da s jedne strane navedene pridržne čeljusti zahvaćaju u utore i tako drže prvi profil, dok se na drugom kraju pritežu nazubljenja ili čeljusti, koje se nalaze na dotičnim pridržnim spojnicama, prema unutarnjoj površini drugog profila. Pritezne odnosno sile držanja za obadva profila su neposredno međusobno ovisne i međusobno neovisno dimenzioniranje steznih sila praktički nije moguće. Zbog toga se moraju održavati odista uske proizvodne tolirancije koje zahtjevaju visoke proizvodne troškove. Ovdje se također ne može ispustiti iz vida da se i dva profila, koji se žele međusobno povezati, a koji su izrađeni kao šuplji profili, također moraju proizvesti s visokom preciznošću, da bi spajanje bilo moguće također i u nepovoljnim slučajevima kod zbrajanja svih tolerancija, kako profilnih tračnica, tako također profilne spojnice. From DE 44 06 208 A1, such a profile coupling with holding jaws is known, which can be brought into engagement with the longitudinal grooves of the first profile to create a solid and fixed connection. The holding jaws are located in each case at the end of the holding couplings, which are located inside the housing, which can be inserted from the front side into the hollow chamber of another profile. The retaining connectors are made bent and have curved outer surfaces that lie on top of each other, over which both retaining connectors are laterally supported. The retaining clips are tightened against each other by means of a screw so that on one side the said retaining jaws engage in the grooves and thus hold the first profile, while on the other end the serrations or jaws, which are on the respective retaining clips, are tightened towards the inner surface of the second profile. The tensile or holding forces for both profiles are directly interdependent and it is practically impossible to dimension the clamping forces independently of each other. Because of this, really tight production tolerances have to be maintained, which require high production costs. It cannot be overlooked here that the two profiles that are to be connected to each other, which are made as hollow profiles, must also be produced with high precision, so that the connection is possible even in unfavorable cases when summing up all the tolerances, as profile rails, as well as profile connectors.

Polazeći od toga zadatak izuma je izraditi profilnu spojnicu tako da se s malim proizvodnim troškovima pouzdano dobije funkcionalno pravilan spoj profilnih tračnica. Profilna spojnica mora omogućiti stabilan i trajan spoj dviju profilnih tračnica s malim proizvodnim i troškovima montaže. Starting from this, the task of the invention is to create a profile connector so that a functionally correct connection of profile rails can be reliably obtained with low production costs. The profile connector must enable a stable and permanent connection of two profile rails with low production and assembly costs.

Rješenje tog zadatka dobiveno je prema značajkama navedenim u prvom patentnom zahtjevu. The solution to this task was obtained according to the features specified in the first patent application.

Predložena profilna sponica odlikuje se funkcionalno pravilnom konstrukcijom i s jednostavnim sredstvima omogućuje stabilan i trajan spoj profilnih tračnica. Pritezanje pridržne spojnice s obje pridržne čeljusti u odnosu na prvu profilnu tračnicu vrši se neovisno o pritezanju profilne spojnice s drugom profilnom tračnicom. Na posebno svrhovit način vrši se odvajanje funkcija tako da se sila držanja steznog elementa za obje profilne tračnice može odgovarajuće zadati unaprijed neovisno o međusobnim zahtjevima. Za spajanje druge profilne tračnice stezni element ima najmanje jedno, svrhovito dva stezna tijela za postizanje prethodnog pritezanja koje djeluje barem djelomično radijalno na unutarnju stranu druge profilne tračnice. Predviđeno je vreteno koje se za izradu spoja može zakrenuti, pri čemu je s jedne strane unaprijed zadana stezna sila uglavnom aksijalno na pridržnu spojnicu, dok se stezno tijelo ili tijela mogu pomaknuti pomoću vretena radijalno prema van zbog pritezanja profilne spojnice s unutarnjom površinom druge profilne tračnice. Stezni element izrađen je svrhovito jednodijelan, ponajprije od čeličnog lima, naročito pernog čelika, i s jedna strane ima pridržnu spojnicu s dvjema pridržnim čeljustima, i s druge strane ima jedno ili dva stezna tijela. Vreteno ima grebene, kose površine, navojne površine ili slično, sa se s jedne strane unaprijed dade aksijalno naprezanje pridržne spojnice, i da se s druge strane omogući radijalno širenje steznog tijela kod izrade spoja. U jednoj alternativnoj, naročitoj izvedbi, aksijalno naprezanje ne zadaje se unaprijed pomoću vretena, već preko poslužnog elementa, koji je, nadalje, predviđen za zakretanje vretena. Poslužni element ima najmanje jednu kosu površinu za stvaranje aksijalnog naprezanja pridržne spojnice. Stezni element nalazi se zajedno s vretenom na svrhovit način najvećim dijelom u kućištu, čiji vanjski oblik je barem djelomično prilagođen unutarnjem obliku drugog profila, koji je izrađen kao profil sa šupljom komorom. Poslužni element je izrađen ponajprije kao kliznik, koji je, zbog zakretanja spomenutog vretena pri izradi spoja, raspoređen svrhovito tako da se može pomicati radijalno u odnosu na os vretena. Poslužni element je izrađen i raspoređen posebno tako da nakon izrade spoja dviju profilnih tračnica zauzima definirani položaj, svrhovito uglavnom unutar kućišta. The proposed profile clamp is characterized by a functionally correct construction and with simple means enables a stable and permanent connection of profile rails. The tightening of the holding coupling with both holding jaws in relation to the first profile rail is done independently of the tightening of the profile coupling with the second profile rail. In a particularly purposeful way, the functions are separated so that the holding force of the clamping element for both profile rails can be appropriately set in advance, independent of mutual requirements. For the connection of the second profile rail, the clamping element has at least one, preferably two clamping bodies to achieve pre-tightening which acts at least partially radially on the inside of the second profile rail. A spindle is provided which can be rotated to make the connection, whereby on the one hand a predetermined clamping force is mainly axially applied to the holding coupling, while the clamping body or bodies can be moved radially outwards by means of the spindle due to the tightening of the profile coupling with the inner surface of the second profile rail . The clamping element is purposefully made in one piece, primarily from sheet steel, especially spring steel, and on one side it has a retaining coupling with two retaining jaws, and on the other side it has one or two clamping bodies. The spindle has ridges, inclined surfaces, threaded surfaces or the like, on the one hand, the axial tension of the retaining coupling is given in advance, and on the other hand, to enable the radial expansion of the clamping body when making the connection. In an alternative, special embodiment, the axial stress is not set in advance by means of the spindle, but via a service element, which is also provided for turning the spindle. The service element has at least one slanted surface to create axial stress on the holding coupling. The clamping element is located together with the spindle in a purposeful way for the most part in the housing, the outer shape of which is at least partially adapted to the inner shape of the second profile, which is made as a profile with a hollow chamber. The service element is made primarily as a slider, which, due to the rotation of the mentioned spindle during the connection, is arranged purposefully so that it can be moved radially in relation to the axis of the spindle. The service element is made and arranged specifically so that after the connection of the two profile rails, it occupies a defined position, purposefully mostly inside the housing.

Daljnji oblici i posebne izvedbe izuma date su u podzahtjevima kao i u daljnjem opisu. Further forms and special embodiments of the invention are given in the subclaims as well as in the further description.

Izum se u nastavku pobliže objašnjava pomoću posebnih izvedbenih primjera, iz kojih ne proizvlazi nikakvo ograničenje izuma. Pri tome In the following, the invention is explained in more detail by means of specific examples, from which no limitation of the invention arises. Thereby

slika 8 prikazuje profilnu spojnicu sa slike 7 bez kućišta. Figure 8 shows the profile connector from Figure 7 without housing.

Slika 1 prikazuje profilnu spojnicu, gledanu u perspektivi, s kućištem 2 i poslužnim elementom 4, za pokretanje vretena koje se nalazi u unutrašnjosti kućišta 2 i ovdje nije dalje prikazano, koje vreteno je svojim krajem uloženo u provrt 6 u dnu kućišta 3 tako da se može se zakrenuti oko uzdužne osi 8. Kućište 2 je izrađeno kao posuda i u unutrašnjosti je šuplje za prihvat spomenutog vretena i steznog elementa. Zatim, stezni element ima pridržne čeljusti za čvrsto i fiksno spajanje s prvim profilom 10, koje čeljusti se još moraju objasniti. Prvi profil 10 kao i drugi profil 12 su međusobno usklađeni kao profili sa šupljom komorom, pri čemu je kućište 2 s umetkom 14 umetnuto čeono u šupljinu drugog profila 12. Vanjski oblik umetka 14 je barem djelomično prilagođen unutarnjem obliku obaju profila 10, 12. Profili 10, 12 imaju načelno kvadratičan presjek i u svojim kutnim područjima imaju uzdužne utore 16 koji idu cijelom duljinom. U skladu s uzdužnim utorima, 16 umetak 14 ima u svoja četiri kuta udubljenja 18 koja gledaju unutra prema uzdužnoj osi 8. Konačno na umetku 14 kućište 2 ima uglavnom prevokutan okvir 20 sa zaobljenim kutevima, međutim bez udubljenja. Okvir 20 strši s unaprijed zadanom širinom preko bočnih površina 24 umetka 14, koje površine idu međusobno pravokutno, tako da okvir 20 tvori dosjedne površine 26 za aksijalne čeone površine drugog profila 12, koje se nalaze jedna nasuprot druge. Prema dolnjem crtežu, slobodna površina 28 kućišta 2, odnosno njegovog okvira 20, leži na vanjskoj površini 30 prvog profila, koja površina 30 gleda prema gore, dok navedene pridržne čeljusti zahvaćaju u obadva uzdužna utora 16 bočno vanjskoj površini 30 pritegnute su. Figure 1 shows a profile coupling, seen in perspective, with a housing 2 and a service element 4, for starting the spindle located inside the housing 2 and not shown here, which spindle is inserted with its end in the hole 6 in the bottom of the housing 3 so that it can be rotated around the longitudinal axis 8. The housing 2 is made like a container and is hollow inside to accept the aforementioned spindle and clamping element. Then, the clamping element has retaining jaws for a firm and fixed connection with the first profile 10, which jaws still need to be explained. The first profile 10 as well as the second profile 12 are coordinated with each other as profiles with a hollow chamber, whereby the housing 2 with the insert 14 is inserted face-on into the cavity of the second profile 12. The outer shape of the insert 14 is at least partially adapted to the inner shape of both profiles 10, 12. Profiles 10, 12 have a basically square section and in their corner areas they have longitudinal grooves 16 that run along the entire length. Corresponding to the longitudinal slots, 16 the insert 14 has in its four corners recesses 18 that look inward towards the longitudinal axis 8. Finally, on the insert 14, the housing 2 has a generally curved frame 20 with rounded corners, but without recesses. The frame 20 protrudes with a predetermined width over the side surfaces 24 of the insert 14, which surfaces are perpendicular to each other, so that the frame 20 forms adjacent surfaces 26 for the axial front surfaces of the second profile 12, which are opposite each other. According to the lower drawing, the free surface 28 of the housing 2, i.e. its frame 20, lies on the outer surface 30 of the first profile, which surface 30 faces upwards, while the said retaining jaws engage in both longitudinal grooves 16 laterally the outer surface 30 is tightened.

Za izradu spoja između dviju profilnih tračnica 10 i 12 poslužni element, odnosno kliznik 4 utisne se u smjeru strelice 32 u šupljinu 34 kućišta 2, odnosno okvira 20. Nakon izrade spoja poslužni element, odnosno kliznik 4 zauzima položaj označen sa 4’ i time je uglavnom potpuno utisnut u kućište 2. Korisnik po tome neposredno vidi da je je spoj bio izrađen pravilno. Suprotno tome, prije izrade spoja kliznik 4 stoji odgovarajuće daleko izvan kućišta 2. Poslužni element 4 je izrađen načelno u obliku slova U i ima povodni element 36, koji korespondira s povodnim tijelom spomenutog vretena. Povodni element 36 je izrađen svrhovito kao nazubljenje, ili zupčanica koja se može dovesti u zahvat s nazubljenjem vretena, tako da se kod uvlačenja poslužnog elementa ili kliznika, za pritezanje steznog elementa, 4 vreteno može zakrenuti oko uzdužne osi 8 za prethodno zadani kut. Time se pridržna spojnica pritegne aksijalno u smjeru strelice A tako da pridržne čeljusti zahvate čvrsto i/ili fiksno u uzdužne utore 16 prvog profila 10. Istovremeno stezna tijela steznog elementa, koja se još moraju objasniti, utisnu se radijalno u smjeru strelice B prema van tako da se bočne površine 24 kućišta pritisnu na unutarnju površinu drugog profila 12. Sile pristezanja, koje odgovaraju strelicama A i B, međusobno su neovisne, pri čemu se prema izumu postiže funkcionalno odvajanje spajanja s prvim profilom 10 s jedne strane i s drugim profilom 12 s druge strane. To make the connection between the two profile rails 10 and 12, the service element, i.e. the slider 4 is pressed in the direction of the arrow 32 into the cavity 34 of the housing 2, i.e. the frame 20. After making the connection, the service element, i.e. the slider 4 occupies the position marked with 4' and thus mostly completely pressed into the housing 2. The user immediately sees that the connection was made correctly. On the contrary, before making the connection, the slide 4 stands sufficiently far outside the housing 2. The service element 4 is made in principle in the shape of the letter U and has a guide element 36, which corresponds to the guide body of the mentioned spindle. The guide element 36 is purposefully made as a toothing, or a gear that can be brought into engagement with the toothing of the spindle, so that when the service element or slide is pulled in, to tighten the clamping element, the spindle 4 can be rotated around the longitudinal axis 8 by a predetermined angle. This tightens the holding coupling axially in the direction of arrow A so that the holding jaws engage firmly and/or fixedly in the longitudinal grooves 16 of the first profile 10. At the same time, the clamping bodies of the clamping element, which still need to be explained, are pressed radially outward in the direction of arrow B so that the side surfaces 24 of the housing are pressed against the inner surface of the second profile 12. The landing forces, which correspond to arrows A and B, are independent of each other, whereby, according to the invention, a functional separation of the connection with the first profile 10 on one side and with the second profile 12 on the other is achieved sides.

Slika 2 prikazuje bočni izgled već spomenutog steznog elementa 40, koji je svrhovito izrađen jednodijelno kao limeni dio, naročito od pernog čelika. Stezni element 40 na svojem kraju ima pridržnu spojnicu 42 za spajanje s prvim profilom, a na drugom kraju ima dva stezna tijela 44, 45. Između pridržnih čeljusti i dvaju steznih tijela 44, 45 nalaze se kutni dijelovi 46, 47, koji omogućuju odvajanje aksijalnog i radijalnog početnog naprezanja. Obadva stezna tijela 44, 45 i kutni dijelovi 46, 47 raspoređeni su u unutrašnjosti kućišta koje ovdje dalje nije prikazano, dok pridržna spojnica 42 barem djelomično strši van iz kućišta, odnosno iz njegovog pravokutnog okvira. Stezni element 40 izrađen je štancanjem iz jednog jedinog komada čeličnog lima i zatim je savijanjem dobiven prikazani, odnosno objašnjeni oblik. Figure 2 shows the side view of the already mentioned clamping element 40, which is purposely made in one piece as a sheet metal part, especially from spring steel. At its end, the clamping element 40 has a holding coupling 42 for connection with the first profile, and at the other end it has two clamping bodies 44, 45. Between the holding jaws and two clamping bodies 44, 45, there are corner parts 46, 47, which enable separation of the axial and radial initial stress. Both clamping bodies 44, 45 and corner parts 46, 47 are arranged in the interior of the housing, which is not further shown here, while the holding coupling 42 at least partially protrudes out of the housing, i.e. from its rectangular frame. Clamping element 40 is made by stamping from a single piece of sheet steel and then by bending it is obtained the shape shown, that is, explained.

Unutar steznog elementa nalazi se vreteno 50. Vreteno 50 ima grebene 52, 53, koji se mogu dovesti u zahvat sa steznim tijelima 44, 45 tako da se kod zakretanja oko uzdužne osi stezna tijela 44, 45 pritiskaju prema strelici B radijalno prema van. Pridržnoj čeljusti 42 pridružena je nadalje kosa površina 54, koja djeluje zajedno s spojnim dijelom 56 vretena 50. Spojni dio 56 je ovdje izrađen kao radijalni umetak, koji naliježe na prednju kosu površinu 54 steznog elementa 40, odnosno pridržne spojnice 42 tako da kod zakretanja vretena 50 na pridržnu spojnicu 42 djeluje aksijalna stezna sila u smjeru strelice A. U nezatetnutom stanju pridržna spojnica 42 dovodi se se s jedne strane u zahvat s prvim profilom, a umetak kućišta utakne se, nadalje, u unutarnji šuplji dio drugog profila. Zatim se vreteno 50 zakrene pomoću poslužnog elementa 4 tako da istovremeno nastaje aksijalna sila stezanja u smjeru strelice A i radijalna sila stezanja u smjeru strelice B. Inside the clamping element there is a spindle 50. The spindle 50 has ridges 52, 53, which can be brought into engagement with the clamping bodies 44, 45 so that when rotating around the longitudinal axis, the clamping bodies 44, 45 are pressed radially outwards according to arrow B. Attached to the retaining jaw 42 is a slanted surface 54, which acts together with the connecting part 56 of the spindle 50. The connecting part 56 is made here as a radial insert, which abuts on the front slanted surface 54 of the clamping element 40, i.e. the holding coupling 42 so that when the spindle is rotated 50, an axial clamping force acts on the holding coupling 42 in the direction of arrow A. In the undamaged state, the holding coupling 42 is brought into engagement with the first profile on one side, and the housing insert is further inserted into the inner hollow part of the second profile. Then the spindle 50 is rotated by means of the service element 4 so that an axial clamping force in the direction of arrow A and a radial clamping force in the direction of arrow B are simultaneously generated.

U alternativnoj izvedbi, umjesto umetaka ili spojnog dijela vreteno ima vanjske navoje, koji ulaze u odgovarajuće unutarnje navoje steznog elementa 40, odnosno pridržne spojnice 42. Također, kod zakretanja vretena 50 vijčani spoj s navojnim, odnosno kosim površinama omogućuje na svrhovit način aksijalno pomicanje i pritezanje pridržne spojnice. In an alternative version, instead of an insert or a connecting part, the spindle has external threads, which enter the corresponding internal threads of the clamping element 40, i.e. the holding coupling 42. Also, when rotating the spindle 50, the screw connection with threaded, i.e. slanted surfaces allows for purposeful axial movement and tightening of the holding coupling.

Slika 3 prikazuje stezni element koji se u usporedbi sa slikom 2 nalazi u položaju zakrenutom za 90o oko uzdužne osi 8. Kao što se vidi, pridržna spojnica 42 na svojim slobodnim krajevima ima pridržne čeljusti 58, 59, koje mogu zahvatiti otraga urezane uzdužne utore profilne tračnice. Figure 3 shows the clamping element, which, compared to Figure 2, is in a position rotated by 90o around the longitudinal axis 8. As can be seen, the holding coupling 42 has holding jaws 58, 59 at its free ends, which can engage the longitudinal slots of the profile rails.

Slobodan razmak 60 između krajeva pridržnih čeljusti 58, 59 u okviru izuma svrhovito je za unaprijed zadanu veličinu manji od širine 62 vanjske površine 30 prvog profila 10, koja je ovdje prikazana samo djelomično i crtako. Kod postavljanja na profil 10 pridržna spojnica 42 se najprije raširi, dok pridržne čeljusti 58, 59 uskoče u otraga urezane uzdužne utore 16 profila 10. The free distance 60 between the ends of the holding jaws 58, 59 within the scope of the invention is expediently for a predetermined size smaller than the width 62 of the outer surface 30 of the first profile 10, which is shown here only partially and graphically. When placed on the profile 10, the holding connector 42 first expands, while the holding jaws 58, 59 snap into the longitudinal slots 16 of the profile 10 cut at the back.

Slika 4 prikazuje, gledan aksijalno, stezni element 40 s pridržnom spojnicom 42 i obadva kutna dijela 46, 47, te stezna tijela 44, 45. Kroz pridržnu spojnicu 42 ide prva uzdužna ravnina 64, a kroz stezna tijela 44, 45 ide druga uzdužna ravnina 66, koje stoje uglavnom okomito prema prvoj uzdužnoj ravnini 64. Budući da, nadalje, stezna tijela 44, 45 nisu povezana s pridržnom spojnicom izravno, već preko kutnog dijela 46, 47, moguće je funkcionalno odvajanje aksijalnog pomicanja odnosno prednaprezanja proizvedenog pomoću pridržne spojnice 42. Figure 4 shows, viewed axially, the clamping element 40 with the holding coupling 42 and both corner parts 46, 47, and clamping bodies 44, 45. The first longitudinal plane 64 passes through the holding coupling 42, and the second longitudinal plane passes through the clamping bodies 44, 45 66, which stand generally perpendicular to the first longitudinal plane 64. Since, furthermore, the clamping bodies 44, 45 are not connected to the holding coupling directly, but through the corner part 46, 47, it is possible to functionally separate the axial movement, i.e. the prestress produced by means of the holding coupling 42 .

Slika 5 prikazuje bočni izgled vretena 50 s već spomenutim povodnim tijelom 68, koje je izrađeno kao vanjsko nazubljenje i može se dovesti u zahvat s povodnim elementom, odnosno nazubljenjem objašnjenog poslužnog elementa. Povodno tijelo 68, odnosno vanjska nazubljenja su svrhovito izrađena kao segment koji se proteže preko unaprijed određenog kutnog područja, s kojim se posebno može dovesti u zahvat nazubljenje ili zupčanica poslužnog elementa. Kod ulavnom U-oblika izvedbe poslužnog elementa prema slici 1, jedan krak je izrađen kao zupčanica, dok drugi krak s unutarnjom površinom naliježe na uglavnom cilindričnu površinu umetka. Time je poslužni element, odnosno kliznik oblika slova U omogućuje radijalno ulaganje ili uvođenje umetka, koji prodire u slobodan prostor između dvaju objašnjenih krakova poslužnog elementa. Figure 5 shows the side view of the spindle 50 with the already mentioned guide body 68, which is made as an external serration and can be brought into engagement with the guide element, i.e. the serrations of the explained service element. The water body 68, that is, the external serrations, are purposefully made as a segment that extends over a predetermined angular area, with which the serration or gear of the service element can be brought into engagement. In the main U-shaped design of the service element according to Figure 1, one leg is made as a gear, while the other leg with an inner surface rests on the generally cylindrical surface of the insert. Thus, the service element, i.e. the U-shaped slide, enables the radial insertion or insertion of an insert, which penetrates into the free space between the two explained arms of the service element.

Nadalje, prikazan je greben 52 za radijalno pomicanje steznog tijela. Na drugom kraju vreteno 50 ima provrt za prihvat objašnjenog i kao umetak izrađenog spojnog dijela. Suptroni kraj 70 vretena 50 ima takav vanjski promjer da se može umetnuti i/ili uložiti pomoću već spomenutog i na slici 1 prikazanog provrta 6 u dnu kućišta. Furthermore, a ridge 52 is shown for radial movement of the clamping body. At the other end, the spindle 50 has a hole for receiving the connecting part explained and made as an insert. The subtronic end 70 of the spindle 50 has such an outer diameter that it can be inserted and/or inserted using the already mentioned and shown in Figure 1 hole 6 in the bottom of the housing.

Za spomenutu alternativnu izvedbu u okviru izuma vreteno 50 može kao spojni dio imati također vanjski navoj 72, koji zahvaća u odgovarajući unutarnji navoj pridržne spojnice 42, da bi se za izradu spoja silom nametnulo aksijalno pomicanje i pritezanje pridržne spojnice 42. For the mentioned alternative embodiment within the framework of the invention, the spindle 50 can also have an external thread 72 as a connecting part, which engages in the corresponding internal thread of the holding coupling 42, in order to force the axial movement and tightening of the holding coupling 42 to make the connection.

Slika 6 prikazuje vreteno 50 gledano aksijalno u smjeru VI s obadva radijalna grebena 52, 53. Ti grebeni 52, 53 leže unutra na objašnjenim steznim tijelima 44, 45 tako da se kod zakretanja vretena 50 stezna tijela mogu pomaknuti radijalno prema van. Grebeni 52, 53 s jedne strane i kosa površina ili vijačana površina s druge strane, koja je pridružena pridržnoj spojnici, su dimenzionirane međusobno neovisne zbog neovisnog prethodnog zadavanja radijalnih i aksijalnih steznih sila. Figure 6 shows the spindle 50 viewed axially in the VI direction with both radial ridges 52, 53. These ridges 52, 53 lie inside the explained clamping bodies 44, 45 so that when the spindle 50 rotates, the clamping bodies can move radially outward. The ridges 52, 53 on the one hand and the inclined surface or the screwed surface on the other hand, which is attached to the holding coupling, are dimensioned mutually independent due to the independent pre-setting of the radial and axial clamping forces.

Slike 7 i 8 prikazuju posebnu izvedbu profilne spojnice, pri čemu na slici 8 nije prikazano kućište. Prema slici 7 kućište 2 ima bočno otvor 84 za najmanje jedne pridržne čeljusti 86, 87 steznog tijela smještenog unutar kućišta 2. Dijametralno prema uzdužnoj osi vretena 50 kućište 2 ima odgovarajući drugi otvor za pridržne čeljusti drugog steznog elementa koje su na odgovarajući način tamo predviđene. Kod utiskivanja poslužnog elementa 4 i zakretanja vretena 50 pridržne čeljusti 86, 87 se dolaze do unutarnje površine profilne tračnice, u koju je ugurano kućište 2, i zakoče se za tu unutarnju površinu na već objašnjen način. Pridržne čeljusti 86, 87 imaju ponajprije šiljke ili zupce 88, koji kod pritezanja omogućuju visok površinski pritisak na unutarnju površinu spomenutog profila. Na svrhovit način, pomoću pridržnih čeljusti 86, 87 i posebno njihovih zubaca 88, kod pritezanja se postižu zaostale deformacije u unutarnjoj površini spomenutog profila, tako da je konačno izrađen također čvrsti spoj. Izravnim zahvatom pridržnih čeljusti i/ili njihovih zubaca povisuje se otpor prema izvlačenju profilne spojnice iz spomenute profilne tračnice i na posebno svrhovit način optimiran je s malim troškovima. Figures 7 and 8 show a special design of the profile connector, while Figure 8 does not show the housing. According to Figure 7, the housing 2 has a lateral opening 84 for at least one holding jaws 86, 87 of the clamping body located inside the housing 2. Diametrically to the longitudinal axis of the spindle 50, the housing 2 has a corresponding second opening for the holding jaws of the second clamping element, which are appropriately provided there. When pressing the service element 4 and rotating the spindle 50, the holding jaws 86, 87 reach the inner surface of the profile rail, into which the housing 2 is inserted, and are locked against that inner surface in the manner already explained. Holding jaws 86, 87 primarily have spikes or teeth 88, which enable high surface pressure on the inner surface of the mentioned profile during tightening. In a purposeful way, with the help of holding jaws 86, 87 and especially their teeth 88, during tightening, residual deformations are achieved in the inner surface of the mentioned profile, so that finally a solid connection is also made. The direct engagement of the holding jaws and/or their teeth increases the resistance to the extraction of the profile connector from the mentioned profile rail and is optimized in a particularly purposeful way with low costs.

Aksijalno pritezanje pridržne sponice 42 postiže se izravno pomoću poslužnog elementa 4. Poslužni element 4 ima na najmanje jednom od svojih krakova 90, 91 kosu površinu ili klinastu površinu 92. Krakovi 90, 91 zahvaćaju u kutni dio 46, 47. Krakovi 90, 91 svojom dolnjom stranom, koja se vidi na slici 7, naliježu na dolnju dosjednu površinu 94 udubljenja 34. Osim udubljenja 34 u prednjem dijelu okvira 95, koje se na slici 7 vidi, kućište 1 ima i odgovarajuće drugo udubljenje na stražnjoj strani u stražnjem dijelu okvira 96. Ako je poslužni element 4 potpuno uguran u kućište 2, odnosno njegov okvir, onda su slobodni krajevi obaju krakova 90, 91 poduprti i uležajeni na odgovarajućim prihvatnim površinama u stražnjem dijelu okvira 96. Axial tightening of the retaining clip 42 is achieved directly by means of the service element 4. The service element 4 has on at least one of its arms 90, 91 a slanted surface or a wedge-shaped surface 92. The arms 90, 91 engage in the corner part 46, 47. The arms 90, 91 with their the lower side, which can be seen in figure 7, rest on the lower adjacent surface 94 of the recess 34. In addition to the recess 34 in the front part of the frame 95, which can be seen in figure 7, the housing 1 also has a corresponding second recess on the back side in the rear part of the frame 96 If the service element 4 is completely pushed into the housing 2, i.e. its frame, then the free ends of both arms 90, 91 are supported and rested on the corresponding receiving surfaces in the rear part of the frame 96.

Kako se vidi na slici 8, krak 80 zahvaća u kutni dio 46, a drugi krak 91 zahvaća odgovarajuće u drugi bočni kutni dio 47. Kosa površina 92 pridružena je gornjem poprečnom segmentu kutnog dijela 47, pri čemu je pridržna spojnica 42 predviđena na drugoj strani u odnosu na poslužni element 4. As can be seen in Figure 8, the arm 80 engages in the corner part 46, and the other arm 91 engages correspondingly in the second side corner part 47. The inclined surface 92 is attached to the upper transverse segment of the corner part 47, with the holding joint 42 provided on the other side in relation to service element 4.

Klinasta ili kosa površina prvog kraka 90, koja se ovdje ne vidi, pridružena je gornjem segmentu 98 prvog kutnog dijela 46. Kad je poslužni element 4 utaknut, tada je kosa površina 82 povezana s unutarnjom stranom dotičnog gornjeg segmenta 98 kutnog dijela 46, 47 u tako, da pridržni element 42 vrši aksijalno pomicanje u smjeru strelice A. Aksijalno naprezanje vrši se na svrhovit način neposredno pomoću poslužnog elementa 4, preko kojeg se prema izumu istovremeno vrši zakretanje na vretenu 50 za radijalno pritezanje steznih tijela 44, 45. A wedge or beveled surface of the first arm 90, not seen here, is associated with the upper segment 98 of the first corner portion 46. When the service element 4 is inserted, then the beveled surface 82 is connected to the inside of the respective upper segment 98 of the corner portion 46, 47 in so that the holding element 42 performs an axial movement in the direction of arrow A. The axial tension is performed in a purposeful manner directly by means of the service element 4, through which, according to the invention, the spindle 50 is simultaneously rotated for the radial tightening of the clamping bodies 44, 45.

U alternativnoj izvedbi izuma, koja ovdje nije prikazana, može se, prema izumu, na dolnjoj vidljivoj strani poslužnog elementa 4, također prema slici, rasporediti najmanje jedna kosa površina poslužnog elementa, koja je, u usporedbi s oblikom izvedbe sa slika 7, 8, u odnosu na uzdužnu os 8 zakrenuta za 180o. Tada za podupiranje i nalijeganje poslužnog elementa 4 u udubljenju 34 odgovarajuće služi gornja dosjedna površina udubljenja 34, koja je slijedeća do umetka kućišta. Neovisno o dotičnoj izvedbi, aksijalno pomicanje pridržne spojnice 42 za učvršćenje pripadne profilne tračnice unaprijed je zadano neposredno pomoću poslužnog elementa 4 preko kose površine ili klinaste površine, koja djeluje zajedno s poslužnim elementom 4. In an alternative embodiment of the invention, which is not shown here, it is possible, according to the invention, on the lower visible side of the service element 4, also according to the figure, to arrange at least one slanted surface of the service element, which, compared to the form of the embodiment from figures 7, 8, in relation to the longitudinal axis 8 rotated by 180o. Then, the upper adjacent surface of the recess 34, which is next to the housing insert, is used to support and rest the service element 4 in the recess 34. Irrespective of the respective design, the axial movement of the holding coupling 42 for fixing the associated profile rail is predetermined directly by means of the operating element 4 via a slanted surface or a wedge surface, which acts together with the operating element 4.
