Description

Izum se odnosi na vezni element za pričvršćivanje veznih elemenata, kao montažnih bočnih zidova ili sl., u razdjelnim kutijama, s osnovnim tijelom, koji se sjedne strane može pričvrstiti na noseći element, a s druge strane na element za pričvrščivanje u razdjelnoj kutiji, pri čemu se na osnovnom tijetu nalazi dosjedna ploha i njoj uglavnom na suprotnoj strani učvrsni (zaustavni) izdanak-graničnik, koji se može skoro paraleleno elastično pomicati prema dosjednoj plohi. The invention relates to a connecting element for attaching connecting elements, such as prefabricated side walls or the like, in distribution boxes, with a basic body, which can be attached on one side to the supporting element, and on the other side to the fastening element in the distribution box, whereby there is an adjacent surface on the base body and, mostly on the opposite side, a solidifying (stopping) outgrowth-limiter, which can move elastically almost parallel to the adjacent surface.

U razdjelnim kutijama čcsto se pričvršćuju noseći elementi, kao bočni montažni zidovi ili sl., na koje se dalje pričvršćuju nosive tračnice za električne aparate, prekidače i tome slično. Ti bočni montažni zidovi trebaju se na što jednostavniji način pričvrstiti u razdjelnim kutijama. Problem jednostavnog pričvršćivanja bočnih zidova u razdjelnim kutijama javlja se osobito tada, kada su električni aparati već pričvršćcni izvan razdjelne kutije na nosive tračnice, a te su opet izvan razdjelne kutije povezane s bočnim montažnim zidovima. U tom slučaju cijela građevna grupa, koja se sastoji od električnih aparata, razdjelnih tračnica i montažnih bočnih zidova, mora se smjestiti u razdjelnu kutiju i zatim u njoj pričvrstiti. Load-bearing elements, such as side mounting walls or the like, are often attached to junction boxes, to which load-bearing rails for electrical appliances, switches and the like are attached. These side mounting walls should be attached as simply as possible in the distribution boxes. The problem of simple fastening of the side walls in distribution boxes occurs especially when the electrical devices are already attached outside the distribution box to the load-bearing rails, and these are again connected to the side assembly walls outside the distribution box. In this case, the entire building group, which consists of electrical devices, distribution rails and prefabricated side walls, must be placed in the distribution box and then fixed in it.

Zadatak predočenog izuma je, dati na raspolaganje vezni element, s kojim se noseći elementi, kao montažni bočni zidovi ili sl., mogu posebno jednostavno pričvrstiti u razdjelnoj kutiji. The task of the presented invention is to make available a connecting element, with which supporting elements, such as prefabricated side walls or the like, can be especially easily attached in the junction box.

Prema izumu taj će se zadatak riješiti prema vrsti veznog elementa tako, da se može pričvrstiti na dosjednu plohu veznog elementa i da osnovni tijelo ima najmanje jednu bočnu plohu, na kojoj se može pričvrstiti noseći element. According to the invention, this task will be solved according to the type of connecting element so that it can be attached to the adjacent surface of the connecting element and that the main body has at least one side surface, on which the supporting element can be attached.

Pomoću veznih elemenata prema izumu pričvršćivanjc nosećih elemenata, kao montažnih bočnih zidova ili sl., u razdjelnim kutijama je posebno jednostavno izvedivo zato, što se noseći elementi postave ili samostalno ili kao već predhodno instalirane građevne grupe s nosivim tračnicama itd., prvenstveno na njenom donjem rubu u razdjelnoj kutiji, prvenstveno se stavi na jedan posebno za to predviđeni držač, pri čemu su gore koso prema van nagnuti i zatim zakrenuti s njihovim gornjim krajem prema unutra, dok se vezni element prema izumu ne nasloni s dosjednom plohom na element za pričvršćivanje i element za pričvršćivanje istovremeno zakvači za učvrsni izdanak. By means of the connecting elements according to the invention, the fastening of supporting elements, such as prefabricated side walls or the like, in distribution boxes is particularly simple, because the supporting elements are placed either independently or as pre-installed building groups with supporting rails, etc., primarily on its lower edge in the distribution box, it is primarily placed on a specially designed holder, whereby they are tilted outwards obliquely and then turned with their upper end inwards, until the connecting element according to the invention rests with its adjacent surface on the fastening element and the fastening element simultaneously latches onto the reinforcing shoot.

Noseći element je poslije toga već čvrsto zakvačen u razdjelnoj kutiji. Da bi se osiguralo od slučajnog rastavljanja, može se prema daljnjem obliku izuma predvidjeti, da se u osnovnom tijelu načini provrt koji završava na dosjednoj plohi, koja služi za prihvat veznog elementa, npr. vijka, za učvrsni element. Pomoću vijka može se vezni element, a s time također i nosivi element bez problema pričvrstiti na element za pričvršćivanje razvodne kutije, bcz posebnog napora, zato što je nosivi element vcć dobro učvršćen u svojem željenom položaju. After that, the supporting element is already firmly clamped in the distribution box. In order to ensure against accidental disassembly, according to a further form of the invention, it can be provided that a hole is made in the basic body that ends on an adjacent surface, which is used to receive a connecting element, for example a screw, for a fastening element. With the help of a screw, the connecting element, and thus also the bearing element, can be attached to the junction box fastening element without any problems, with special effort, because the bearing element is already well fixed in its desired position.

Daljnja obilježja i prednosti vide se iz slijedećeg opisa izvedbenog primjera izuma. Further features and advantages can be seen from the following description of an embodiment of the invention.

Slika 1 prikazuje isječak iz razdjelne kutije s bočnim zidom pričvršćenim preko veznog elementa prema izumu, pri čemu je vezni element prikazan u presjeku prema crti 1 - 1 u Sl. 2, Sl. 2 nacrt na raspored sa Sl. 1 u povećanom mjerilu s odstranjenim učvrsnim elementom, Sl. 3 nacrt na vezni element odgovarajući Sl. 2, Sl. 4 pogled na vezni element u Sl. 3 odozdo, Sl. 5 presjek kroz vezni element uzduž crte V-V u Sl. 4, Sl. 6 presjek kroz vezni element sa Sl. 4 uzduž crte VI -VI u Sl. 4, a St. 7 presjek kroz vezni element iz Sl. 4 uzduž crte VII -VII. Fig. 1 shows a section of a junction box with a side wall attached via a connecting element according to the invention, where the connecting element is shown in section along the line 1 - 1 in Fig. 2, Fig. 2 layout plan with Fig. 1 in an enlarged scale with the fastening element removed, Fig. 3 drawing on the connecting element corresponding to Fig. 2, Fig. 4 view of the connecting element in FIG. 3 from below, Fig. 5 section through the connecting element along the line V-V in FIG. 4, Fig. 6 section through the connecting element from Fig. 4 along the line VI -VI in Fig. 4, and St. 7 section through the connecting element from Fig. 4 along the line VII -VII.

U Sl. 1 je prikazan isječak iz razdjelne kutije, pri čemu je s 1 obilježen jedan bočni zid razdjelne kutije. Na stranici obilježenoj s 2 u Sl. 1 mogu biti raspoređena vrata razdjelne kutije. U predjelu bočnog zida 1 razdjelne kutije je pomoću veznog etementa 3 prema izumu, pričvršćen montažni bočni zid 4, kao što se vidi u Sl. 2. U tu svrhu je na pokrovu 5 razdjelne kutije postavljen element za pnčvršćivanje 6 u obliku učvrsnog kutnika npr. navijčan ili zakovan. Vezni element 3 time predstavlja vezu između učvrsnog kutnika 6 i montažnog bočnog zida 4. In Fig. 1 shows a section from the distribution box, where one side wall of the distribution box is marked with 1. On the page marked with 2 in Fig. 1 the junction box door can be arranged. In the area of the side wall 1 of the distribution box, a mounting side wall 4 is attached using the connecting element 3 according to the invention, as seen in Fig. 2. For this purpose, on the cover 5 of the distribution box, a fastening element 6 is placed in the form of a reinforcing corner, for example screwed or riveted. The connecting element 3 thus represents the connection between the reinforcing corner 6 and the mounting side wall 4.

Na svojem donjem, u Sl. 1 ne prikazanom kraju, prikazan je montažni bočni zid u predjelu poda razdjelne kutije, pri čemu su pričvršćenja odabrana na uobičajen način. Vrsta prihvata montažnog bočnog zida 4 u predjelu poda razdjetne kutije nije za ovaj izum od posebnog značenja i može se izvesti po volji. Preduvjet je samo, da se montažni bočni zid može pomicati ili u smjeru duple strelice 7 u razdjelnoj kutiji ili u smjeru duple strelice 8 što bi imalo prednost. On its lower part, in Fig. 1 at the end not shown, the assembly side wall is shown in the area of the floor of the junction box, the fixings being selected in the usual way. The type of acceptance of the assembled side wall 4 in the area of the floor of the children's box is not of particular importance for this invention and can be performed as desired. The only prerequisite is that the assembled side wall can be moved either in the direction of the double arrow 7 in the distribution box or in the direction of the double arrow 8, which would have an advantage.

Kao što je u Sl. 3 do 7 točno vidljivo, vezni element 3 prema izumu sastoji se od osnovnog tijela 9, na kojem je preko elastičnog jezičca 10 raspoređen učvrsni izdanak 11. Između osnovnog tijela 9 i jezičca 10 je predviđena istaka ili utor 12, da bi se mogao izradi dulji jezičac 10 i da bi se olakšalo povratno elastično vraćanje jezičca 10 uzduž strelice 13 As in Fig. 3 to 7 clearly visible, the connecting element 3 according to the invention consists of a basic body 9, on which a strengthening protrusion 11 is arranged over an elastic tab 10. Between the basic body 9 and the tab 10, a protrusion or groove 12 is provided, so that a longer the tab 10 and to facilitate the return elastic return of the tab 10 along the arrow 13

(Sl. 6). (Fig. 6).

Učvrsni (zaustavni) izdanak 11 leži skoro nasuprot dosjedne plohe 14 na osnovnom tijelu 9, koja čini dosjednu površinu za srednji dio 15 učvrsnog kutnika 6. Kao što je prikazano na Sl. 1, učvrsni (zaustavni) kutnik 6 je učvršćen s jedne strane između dosjedne plohe 14 i s druge strane između zaustavne plohe 16 (Sl. 6) na učvrsnom (zaustavnom) izdanku 11 u smjeru duple strelice 7 odnosno 8. The fastening (stop) protrusion 11 lies almost opposite the adjacent surface 14 on the base body 9, which forms the adjacent surface for the middle part 15 of the fastening angle 6. As shown in Fig. 1, the fastening (stop) angle 6 is fastened on one side between the adjacent surface 14 and on the other side between the stop surface 16 (Fig. 6) on the fastening (stop) protrusion 11 in the direction of the double arrow 7 and 8, respectively.

Na zaustavnoj plohi 16 je leži učvrsni (zaustavni) kutnik 6 sa svojim slobodnim krajem kraka 17. Da bi se spriječilo, da se vezni element 3 nekontrolirano odvoji od učvrsnog kutnika 6, na osnovnom tijelu 9 nalazi se provrt 18, koji zadržava u dosjednoj plohi 14 i služi za prihvat vijka 19. Vijak 19 može pri tome, kao što je prikazano u SI 1, preko kavezne matice 20 veznog elementa 3 povezati s učvrsnim kutnikom 6. U jednom drugom izvedbenom obliku može se naravno primjeniti također samokočni vijak za limove ili tome sl., koji zahvaća u učvrsni kutnik 6. On the stop surface 16 lies the fixing (stop) angle 6 with its free end of the arm 17. To prevent the connecting element 3 from uncontrollably separating from the fixing angle 6, the base body 9 has a hole 18, which holds it in the adjoining surface 14 and serves for the reception of the screw 19. The screw 19 can, as shown in SI 1, be connected to the fastening angle 6 via the cage nut 20 of the connecting element 3. In another embodiment, of course, a self-locking screw for sheet metal or to that fig., which engages in the fastening angle 6.

Za pričvršćivanje veznog elementa 3 na montažni bočni zid 4 na veznom elementu 3 nalaze se dvije bočne plohe 21, 22, koje su smještene simetrično s obzirom na učvrsnu (zaustavnu) istaku 11 odnosno jezičac 10. Taj simetrični smještaj ima prednost, da se jedan te isti vezni element 3 može primjeniti ne samo za desni nego i za lijevi montažni bočni zid 4. Bočne plohe 21, 22 su izrađene tako da se razilaze od učvrsnog izdanka 11 otprilike u V-obliku i pokazuju nagib odgovarajuće savinutom dijelu 30 montažnog bočnog zida 4 (SI. 2). For attaching the connecting element 3 to the assembled side wall 4, the connecting element 3 has two side surfaces 21, 22, which are located symmetrically with respect to the fastening (stop) projection 11, i.e. tab 10. This symmetrical location has the advantage that one and the same connecting element 3 can be used not only for the right but also for the left assembly side wall 4. The side surfaces 21, 22 are made in such a way that they diverge from the reinforcing protrusion 11 in an approximately V-shape and show a slope corresponding to the bent part 30 of the assembly side wall 4 (SI. 2).

Razumije se, da kod odgovarajuće izrade montažnog bočnog zida 4 bočne plohe 21, 22 su uobičajeno postavljene paralelno jedna prema drugoj ili simetrično na drugi način. It is understood that in the appropriate construction of the prefabricated side wall 4, the side surfaces 21, 22 are usually placed parallel to each other or symmetrically in some other way.

U bočnim zidovima 21, 22 završavaju provrti 23, 24, u koje se može uvrnuti npr. samokočni vijci za povezivanje montažnog bočnog zida 4 s veznim elementom 3. Bočni zidovi 21, 22 pokazuju nadalje savinuti nastavak 25, 26, na kojem su poredani nastavci 27, 28, koji zahvaćaju u odgovarajuće provrte na montažnom bočnom zidu 4. The side walls 21, 22 end with holes 23, 24, into which, for example, self-locking screws can be screwed in for connecting the assembled side wall 4 with the connecting element 3. The side walls 21, 22 show a further bent extension 25, 26, on which the attachments are arranged 27, 28, which engage in corresponding holes on the assembly side wall 4.

Ovim sada opisanim poretkom može se najednostavan način pričvrstiti vezni element 3 na montažni zid 4, time da se vezni element 3 s nastavkom 27 ill 28 stavi najprije u odgovarajući provrt u montažni bočni zid 4, a zatim se učvrsti jedan vijak kroz provrt u montažnom bočnom zidu 4 u odgovarajući provrt 23 ili 24 u bočnom zidu 21 ili 22. With this now described order, the connecting element 3 can be attached to the mounting wall 4 in the simplest way, by first placing the connecting element 3 with the extension 27 or 28 in the corresponding hole in the mounting side wall 4, and then fixing one screw through the hole in the mounting side wall. wall 4 into the corresponding hole 23 or 24 in the side wall 21 or 22.

Nakon štoje vezni element 3 pričvršćen baš kao što je sada opisano, na montažni bočni zid 4, taj se može sam ili kao građevna grupa, sastavljena od dva montažna bočna zida s poredanim nosećim tračnicama s električnim upravljačkim aparatima, postaviti u razdjelnu kutiju. To se može provesti ili tako, da se montažni bočni zid 4 odnosno građevna grupa ugurne u smjeru strelice 7 na Sl. 1 u lijevo u razdjelnu kutiju, sve dok učvrsni izdanak (graničnik) 11 ne zakvači krak 17 učvrsnog kutnika 6, kao štoje prikazano na Sl. 1. U drugom izvedbenom obliku može se montažni bočni zid ili jedna cijela građevna grupa ugraditi u razdjelnu kutiju, tako da se ti u SI. 1 koso prema desno gore nagnuti prvo stave u predio poda razdjelne kutije, a zatim u smjeru strelice 8 na lijevo zakrene unutra, sve dok vezni element 3 nije zakvačen s učvrsnim (graničnim, zaustavnim) kutnikom 6. After the connecting element 3 is attached exactly as described now, to the prefabricated side wall 4, it can be placed alone or as a construction group, composed of two prefabricated side walls with aligned support rails with electrical control devices, in the junction box. This can be done either by inserting the prefabricated side wall 4 or the construction group in the direction of the arrow 7 in Fig. 1 to the left in the distribution box, until the strengthening protrusion (limiter) 11 catches the arm 17 of the strengthening angle 6, as shown in Fig. 1. In another embodiment, a prefabricated side wall or one whole building group can be installed in a distribution box, so that in SI. 1 is first placed diagonally to the right upwards in the area of the floor of the distribution box, and then in the direction of the arrow 8 to the left it is turned inward, until the connecting element 3 is locked with the fastening (limit, stop) angle 6.

Zatim se može veza između veznog elementa 3 i učvrsnog kutnika 6 osigurati pomoću vijka 19 s maticom 20. Then, the connection between the connecting element 3 and the reinforcing angle 6 can be secured by means of a screw 19 with a nut 20.

Da bi se olakšalo rastavljanje veznog elementa 3 od učvrsnog kutnika 6, predviđena je nasuprot učvrsnog izdanka 11 na učvrsnom kutniku 6 utor 29, koji se pruža paralelno prema jezičcu 10 1 koji je otvoren prema osnovnom tijelu 9 veznog elementa 3. U tom utoru 29 može se na jednostavan način primjeniti alat, npr. izvijač, i time savinuti jezičac 10 s učvrsnim izdankom 11 u smjeru strelice 13 (Sl. 6), poslije čega se na jednostavan način može izvaditi montažni bočni zid 4 s veznim elementom 3 iz razdjetne kutije. In order to facilitate the disassembly of the connecting element 3 from the fastening corner 6, a slot 29 is provided opposite the fastening projection 11 on the fastening corner 6, which extends parallel to the tab 10 1 which is open to the base body 9 of the connecting element 3. In this slot 29 can a tool, for example a screwdriver, can be used in a simple way, and thus bend the tongue 10 with the hardened protrusion 11 in the direction of the arrow 13 (Fig. 6), after which the assembled side wall 4 with the connecting element 3 can be easily removed from the box.
