Description

Područje na koje se izum odnosi The field to which the invention relates

Ovaj izum odnosi se na zaštitne rešetke za prozore i ostale otvore. This invention relates to protective grilles for windows and other openings.

Tehnički problem Technical problem

Ovaj je problem poznat od davnina rješavao se na bezbroj načina. Zadatak je uvijek isti, a to je, osigurati prozore, vrata, ostakljene stijene i druge otvore protuprovalnom rešetkom. Kod toga je važno da takva zaštita bude prije svega sigurna, a zatim i dekorativna i pristupačna cijenom. Rešetka mora osim toga biti i univerzalna, što znači da se može upotrijebiti za zaštitu otvora raznih dimenzija. To se postiže ovdje pokazanim komponibilnim sistemom, a to opet znači bez zavarivanja ili zakivanja. Bit je komponibilnog sistema da se proizvedu komponibilni elementi, prefabricirani, koji će se na licu mjesta predmontirati u rešetku, i sve bez zavarivanja ili zakivanja. Tako predmontirana rešetka, jednim pokretom dovodi se u stanje potpune čvrstoća, a zatim se jednostavnim načinom sigurno i nerastavljivo pričvršćuje za zid ili na okvir prozora. This problem has been known since ancient times and was solved in countless ways. The task is always the same, which is to secure windows, doors, glazed walls and other openings with burglar bars. In this case, it is important that such protection is first of all safe, and then also decorative and affordable. The grille must also be universal, which means that it can be used to protect openings of various dimensions. This is achieved with the composable system shown here, and again that means no welding or riveting. The essence of the modular system is to produce modular elements, prefabricated, which will be pre-assembled in the grid on site, and all without welding or riveting. The grid, pre-assembled in this way, is brought to a state of complete strength with one movement, and then it is securely and indestructibly attached to the wall or to the window frame in a simple way.

Stanje tehnike State of the art

Zaštitne rešetke za prozore ili druge otvore uglavnom se proizvode po narudžbi u radionicama. Elementi se uglavnom spajaju zavarivanjem ili zakivanjem. Nije poznat sistem gdje bi se prefabricirani elementi predmontirali u tzv. otvorenom položaju, a onda samo jednim pokretom cijeli sistem doveo u tzv. zatvoreni položaj gdje ukršteni elementi rešetke u dodirnim točkama ulaze u tzv. klinč, i time bivaju čvrsto spojeni. Protective grills for windows or other openings are mostly made to order in workshops. Elements are generally joined by welding or riveting. There is no known system where prefabricated elements would be pre-assembled in the so-called open position, and then with just one movement brought the whole system to the so-called closed position where the crossed elements of the grid at the points of contact enter the so-called clinch, and thus they are firmly connected.

Izlaganje suštine izuma Presentation of the essence of the invention

Primarni cilj izuma je učiniti jedan jednostavan, dakle jeftin komponibilni sistem dekorativnih zaštitnih rešetki za zaštitu otvora kao što su prozori prizemlja, svjetlarnici, neki izlozi i drugo. Cilj je također da taj sistem bude toliko jednostavan, da rešetku može sastaviti i montirati i nestručna osoba, uz upotrebu kućnog priručnog alata. Sistem dakako mora biti i univerzalan, tako da se njime mogu zaštititi otvori raznih veličina i oblika. Da bi se to postiglo, sve mora biti izvedivo bez bilo kakvog zavarivanja ili zakivanja, pa tako otpada i naknadna obrada zavarenih mjesta, (čišćenje, brušenje, bojadisanje i sl.). To se ovdje postiže upotrebom sistema prefabriciranih komponibilnih elemenata, i klinč sistemom zatvaranja, koji zamjenjuje zavarivanje ili zakivanje. Naime, svi elementi rešetke imaju na mjestu ukrštanja naročitu perforaciju sa zubom. Na tim mjestima elementi konstrukcije se spajaju ulazeći jedan u drugi, ali samo pod određenim tzv. otvorenim kutom. Nakon pomaka sistema, elementi rešetke se u točkama ukrštanja zakreću jedni prema drugima, odnosno spomenuti kut zatvaraju i ulaze u tzv. klinč, a zubi koji tada čeono nasjedaju jedni na druge, ne dopuštaju više razdvajanje elemenata rešetke. Cijeli se sistem prije ugradnje osigura elastičnim natezačima, pa se može pristupiti ugradnji, koja se može izvršiti učvršćenjem u okvir prozora ili u okolni zid. The primary goal of the invention is to make a simple, therefore cheap modular system of decorative protective grids for the protection of openings such as ground floor windows, skylights, some shop windows and others. The goal is also to make this system so simple that even an unskilled person can assemble and install the grid, using household tools. Of course, the system must also be universal, so that openings of various sizes and shapes can be protected with it. In order to achieve this, everything must be feasible without any welding or riveting, so the subsequent treatment of the welded areas (cleaning, sanding, painting, etc.) is also eliminated. This is achieved here by using a system of prefabricated composable elements, and a clinch closing system, which replaces welding or riveting. Namely, all grid elements have a special perforation with a tooth at the point of intersection. In these places, the elements of the structure are joined by entering one another, but only under certain so-called open angle. After the movement of the system, the elements of the lattice are turned towards each other at the crossing points, i.e. they close the mentioned angle and enter the so-called clinch, and the teeth, which then face each other, no longer allow the separation of the grid elements. Before installation, the entire system is secured with elastic tensioners, so installation can be started, which can be done by fixing it in the window frame or in the surrounding wall.

Detaljan opis jednog od načina ostvarenja izuma i tri načina pričvršćenja rešetke kod ugradnje A detailed description of one of the ways of realizing the invention and three ways of fastening the grid during installation

1. Komponibilna zaštitna prozorska rešetka učvršćena u okolni zid zatvorenim vođenim klinom 1. Modular protective window grill fixed in the surrounding wall with a closed guided wedge

Prema crtežu 6, 7, i 8, zaštitna rešetka se sastoji od osnovnih komponibilnih elemenata, oblikovanih prema spomenutim crtežima i izrađenih od plosnog željeza, te perforiranog i ozubljenog prema crtežu 1 i 2. Izbor komponibilnih elemenata, broj i vrstu, određuju veličina i oblik otvora koji treba zaštiti. Zatim se pristupa predmontiranju odnosno sklapanju rešetke prema crtežima 3, 4 i 5, koji prikazuju način ukrštanja osnovnih elemenata rešetke u tzv. otvorenom položaju (crtež 7). Pomicanjem u smjeru strelica, rešetka se zatvara čime se kut koji osnovni elementi u dodirnim točkama zatvaraju, smanjuje. Dodirne točke ulaze u klinč, zubi čeono nasjedaju jedan na drugi čime se ostvaruje čvrsti spoj, a sama rešetka poprima svoj konačni oblik kako to prikazuje crtež 8. According to drawings 6, 7, and 8, the protective grid consists of basic modular elements, shaped according to the mentioned drawings and made of flat iron, and perforated and toothed according to drawings 1 and 2. The choice of modular elements, number and type, is determined by size and shape opening to be protected. Next, the pre-assembly or assembly of the grid is approached according to drawings 3, 4 and 5, which show the way of crossing the basic elements of the grid in the so-called open position (drawing 7). By moving in the direction of the arrows, the grid closes, which reduces the angle that the basic elements close at the points of contact. The contact points enter the clinch, the teeth face each other, which creates a solid connection, and the grid itself takes its final shape, as shown in drawing 8.

Predmontirana se rešetka privremeno učvršćuje elastičnim natezačima, da se spriječi njeno ponovno otvaranje. Slijedi montaža, odnosno učvršćenje za okolni zid, crtež 12. The pre-assembled grid is temporarily fixed with elastic tensioners to prevent it from opening again. Next comes the assembly, i.e. the fastening to the surrounding wall, drawing 12.

Na paralelne dijelove komponenti 1 i 2, navlače se cjevasti produžni nastavci 10. Vodilicom vođenim svrdlom zabuši se okolni zid, i rešetka postavlja u položaj za ugradnju. Učvršćuje se postavljanjem klinova sa vodilicama, koji se zatim zabijaju do položaja na crtežu 12. Tubular extensions 10 are pulled onto the parallel parts of components 1 and 2. The surrounding wall is drilled with a drill guided by a guide, and the grid is placed in the installation position. It is fixed by placing wedges with guides, which are then driven to the position in drawing 12.

2. Komponibilna zaštitna prozorska rešetka učvršćena za okolni zid zatvorenim samosteznim vijkom za beton 2. Modular protective window grill fixed to the surrounding wall with a closed self-tapping screw for concrete

Nakon predmontiranja rešetke, kako je to već opisano i prikazano u 1, pristupa se ugradnji kako je to prikazano crtežom 11. Vodilicom vođenim svrdlom zabuši se okolni zid. Na paralelne dijelove komponenti 1 i 2 navlače se cjevasti produžni nastavci 10, i rešetka se postavlja u položaj za montažu. Nakon zabijanja samosteznog vijka 13, navlači se stezni umetak 11, pa stezni konus 12, te podloška i matica kojom se skupa pritegne. Stezni konus 12 preko steznog umetka 11 pritisne na elemente rešetke 1 i 2, u cijevnom produžnom nastavku 10, čime je rešetka nerastavljivo učvršćena bez obzira otpusti li se sada matica. After the pre-assembly of the grid, as already described and shown in 1, the installation is approached as shown in drawing 11. The surrounding wall is drilled with a drill guided by a guide. Tubular extensions 10 are threaded onto the parallel portions of components 1 and 2, and the grid is placed in position for assembly. After driving the self-tapping screw 13, the clamping insert 11, then the clamping cone 12, and the washer and nut are tightened together. The clamping cone 12, via the clamping insert 11, presses on the grating elements 1 and 2, in the tubular extension 10, whereby the grating is fixed indissolubly regardless of whether the nut is now loosened.

3. Komponibilna zaštitna prozorska rešetka učvršćena za okvir prozora 3. Modular protective window grill fixed to the window frame

Nakon predmontiranja rešetke, kako je to već opisano i prikazano 1, pristupa se ugradnji učvršćenjem za okvir prozora. Hvatačima 3 i 4, crtež 9, obuhvate paralelni dijelovi rešetke, nakon bušenja provrta u okvir prozora, kroz provrt na hvatačima provlači se vijak sa lomljivom glavom, te držač odstojanja 8. vijkom se sve skupa pritegne, a glava odstrani. Ukoliko rešetka odnosno hvatači ne bi dosegli okvir prozora, upotrebljavaju se tzv. produžni hvatači 3.1 i 4.1 crtež 10. Produžni hvatač učvršćuje se najprije za rešetku vijkom sa lomljivom glavom 6, a zatim sličnim vijkom kroz drugi provrt i za okvir prozora. After pre-assembling the grid, as already described and shown 1, the installation is approached by fixing it to the window frame. Grippers 3 and 4, drawing 9, cover the parallel parts of the grid, after drilling a hole in the window frame, a screw with a breakable head is passed through the hole on the grippers, and the distance holder 8 is tightened with the screw, and the head is removed. If the grid or catchers would not reach the window frame, the so-called extension grippers 3.1 and 4.1 drawing 10. The extension gripper is fixed first to the grid with a screw with a breakable head 6, and then with a similar screw through the second hole and to the window frame.
