The technical problem that is solved by the invention consists in the following: how to realize a construction in which we can place a movable leaf on the door frame over the pulleys, while avoiding bending of the door and difficult opening?

Stanje tehnike State of the art

Kod poznatih dvokrilnih kliznih vrata, krila se oslanjaju na okvir vrata pomoću instalacije za vješanje i vođenje koja sadrži najmanje jednu vodeću tračnicu postavljenu na gornjem dijelu vrata na koju su poskretno postavljeni obrtni koloturi, učvršćeni na krilu ili osloncu fiksiranom na gornjem dijelu krila. Ovakva klizna vrata opisana su npr. u švicarskim patentnim spisima br. 365 844 i 369 567. Međutim, oba gornja rješenja imaju značajan nedostatak koji se sastoji u tome, što su vodeće tračnice postavljene bočno u odnosu na okvir vrata tako da su u odnosu na položaj otvora krila oslonjena tračnicama za vođenje skoro u potpunosti izvan okvira vrata. Pored toga, u slučaju vrata sa dva teleskopska krila, ista će postojati na obje strane vrata, jer su vrata sa središnjim otvorom i klize na svojim tračnicama u suprotnim smjerovima. Ovi dijelovi koji se nalaze izvan okvira vrata, otežavaju pomicanje kompletnih vrata, što posebno dolazi do izražaja pri istovaru na transportna vozila na skladištima ili katovima, gdje vrata trebaju biti postavljena. Isto tako, s gledišta transporta i održavanja se pokazalo, da su dijelovi vodećih tračnica izvan okvira vrata izloženi čestom savijanju i oštećenjima, zbog čega su potrebne česte intervencije. Pored toga, naročito kod vrata sa ležištima i velikim središnjim otvorima, često je neophodno da dijelovi tračnica budu fiksirani na zidu, čime je otežana montaža istih. In known double-leaf sliding doors, the leaves are supported on the door frame by means of a hanging and guiding installation which contains at least one guide rail placed on the upper part of the door, on which are pivoted rotating pulleys, fixed on the leaf or a support fixed on the upper part of the leaf. Such sliding doors are described, for example, in Swiss patent documents no. 365 844 and 369 567. However, both of the above solutions have a significant drawback, which consists in the fact that the guide rails are placed laterally in relation to the door frame, so that in relation to the position of the leaf opening, they are supported by the guide rails almost completely outside the door frame . In addition, in the case of a door with two telescopic leaves, the same will exist on both sides of the door, because the door has a central opening and slides on its tracks in opposite directions. These parts, which are located outside the door frame, make it difficult to move the complete door, which is especially evident when unloading onto transport vehicles on warehouses or floors, where the door should be installed. Likewise, from the point of view of transport and maintenance, it has been shown that the parts of the guide rails outside the door frame are exposed to frequent bending and damage, which is why frequent interventions are necessary. In addition, especially for doors with bearings and large central openings, it is often necessary for parts of the rails to be fixed on the wall, which makes their installation difficult.

Opis rješenja tehničkog problema Description of the solution to the technical problem

Tehnički problem riješen je izumom na taj način, što je najmanje na jednom okviru preko osovine postavljen i fiksiran najmanje jedan kolotur a po kojem je pomična vodeća tračnica pokretna s krilom, i što je najmanje jedan kolotur postavljen na pokretno krilo i pomičan po fiksnoj vodećoj tračnici okvira. The technical problem was solved by the invention in such a way that at least one pulley is mounted and fixed on at least one frame over the axis, and on which the movable guide rail is movable with the wing, and that at least one pulley is mounted on the movable wing and movable along the fixed guide rail frame.

Prednosti dobivene primjenom izuma ogledaju se prije svega u tome, što vrata mogu biti transportirana zajedno sa svojim krilima s prethodno podešenim povlačenjem i isporučuju se u obliku kompaktnog sklopa, bez problema u vezi sa montažom, održavanjem ili utovarom na transportna vozila. Instalacija na katovima, kada su u pitanju vrata s ležištima, može se realizirati s minimumom operacija, odnosno uz veliku uštedu vremena. Štoviše, u svim slučajevima je izbjegnuto pričvršćivanje tračnica na zidovima. The advantages obtained by the application of the invention are primarily reflected in the fact that the doors can be transported together with their wings with a pre-adjusted pull and are delivered in the form of a compact assembly, without problems related to assembly, maintenance or loading onto transport vehicles. Installation on floors, when it comes to doors with bearings, can be realized with a minimum of operations, i.e. with a great saving of time. Moreover, in all cases fixing the rails to the walls was avoided.

Izum će biti bliže opisan na temelju primjera izvođenja prikazanog na crtežima, pri čemu: The invention will be described in more detail on the basis of the embodiment shown in the drawings, whereby:

sl. 7 i 8 prikazuju djelomične presjeke po liniji C-C i D-D sa sl. 5. Fig. 7 and 8 show partial sections along lines C-C and D-D from Fig. 5.

Prema obliku izvođenja sa sl. 1 do 4, okvir 1 vrata nalazi se u položaju predviđenom za spajanje ili zavarivanje elemenata na profiliranom limu. Okvir 1 vrata predviđen je za vješanje identičnih krila 2 i 3 vrata s ležištem koja imaju mogućnost automatskog pomicanja u suprotnim smjerovima istodobno s vratima kabine, pomoću mehanizma koji nije prikazan i koji djeluje s uređajem za povlačenje pričvršćenim na kabini. Na gornjem dijelu okvira 1 raspoređene su dvoje vodeće tračnice 4.1 i 4.2 koje čine komplet tračnica 4 pričvršćen na okvir 1 vrata. Ispod svakog kraja vodećih tračnica 4 i na određenoj udaljenosti od istih, postavljeni su vodeći koloturi 5 i 6 koji mogu rotirati oko osovine fiksirane na okviru 1 vrata. According to the form of execution from Fig. 1 to 4, the frame 1 of the door is in the position provided for connecting or welding the elements on the profiled sheet. The door frame 1 is designed to hang identical door leaves 2 and 3 with a bed that has the ability to automatically move in opposite directions simultaneously with the cabin door, by means of a mechanism not shown that works with a pull device attached to the cabin. On the upper part of the frame 1, two guide rails 4.1 and 4.2 are arranged, which form a set of rails 4 attached to the door frame 1. Under each end of the guide rails 4 and at a certain distance from them, guide pulleys 5 and 6 are placed which can rotate around a shaft fixed on the frame 1 of the door.

Poprečne grede 7 i 8 su učvršćene na gornjim dijelovima krila 2 i 3 respektivno. Svaka od greda 7, 8 nosi po jednu tračnicu 9, 10 tako da prekrivaju u znatnoj mjeri odgovarajuća krila i prelaze neznatno izvan istih, na način koji omogućava pomicanje na odgovarajućim koloturima 5, 6 pri otvaranju i zatvaranju vrata. Sa strane okrenute prema drugom krilu, svaka od greda 7, 8 sadrži produžetke u obliku poluga 11, 12 čija je duljina nešto veća od duljine krila i na čije krajeve su smješteni kotrljajući koloturi 13, 14 koji se kreću po vodećoj tračnici 4 fiksiranoj na okviru 1. Kao što se može vidjeti sa sl. 1 i 3, poluga 12 kao produžetak poprečne grede 8 od krila 3 i u položaj u zatvaranja prelazi preko grede 7 fiksirane na drugom krilu, gdje je, radi omogućivanja slobodnog pomicanja odgovarajućeg kolotura 14, predviđen izduženi otvor 7.1. Vodeća tračnica 4, fiksirana na okviru 1 vrata i vodeće tračnice 9, 10 pokretne na krilima 2, 3 predstavljaju dio sklopa kontratračnice 4.3, 9.1, 10.1 za koloture 13, 14 i 5, 6 (sl. 3 i 4). Fiksni koloturi 5, 6 nošeni s okvirom 1 vrata, vodeće tračnice 9, 10 pokretne sa krilima, pokretni koloturi 13, 14 nošeni s polugama 11, 12 i dvije nosive tračnice 4.1, 4.2 koje formiraju kontinuirani par tračnica 4, formiraj u dvije instalacije za vješanje i vođenje krila s kojima, u položaj u zatvaranja vrata, ni najmanji dio vodećih tračnica ne prelazi okvir 1 vrata. The transverse beams 7 and 8 are fixed on the upper parts of the wings 2 and 3 respectively. Each of the beams 7, 8 carries one rail 9, 10 so that they cover to a considerable extent the corresponding wings and pass slightly beyond them, in a way that enables movement on the corresponding pulleys 5, 6 when opening and closing the door. On the side facing the other wing, each of the beams 7, 8 contains extensions in the form of levers 11, 12, the length of which is slightly greater than the length of the wing and at the ends of which are placed the rolling pulleys 13, 14 that move along the guide rail 4 fixed on the frame 1. As can be seen from Fig. 1 and 3, the lever 12 as an extension of the transverse beam 8 of the wing 3 and in the closed position passes over the beam 7 fixed on the second wing, where, in order to enable free movement of the corresponding pulley 14, an elongated opening 7.1. The guide rail 4, fixed on the frame 1 of the door and the guide rails 9, 10 movable on the wings 2, 3 represent part of the assembly of the counter rail 4.3, 9.1, 10.1 for the pulleys 13, 14 and 5, 6 (fig. 3 and 4). Fixed pulleys 5, 6 carried with the door frame 1, guide rails 9, 10 movable with wings, movable pulleys 13, 14 carried with levers 11, 12 and two bearing rails 4.1, 4.2 which form a continuous pair of rails 4, form in two installations for hanging and guiding the wings with which, in the closed position of the door, even the smallest part of the guide rails does not exceed the frame 1 of the door.

Sl. 5 do 8 ilustriraju drugi oblik izvođenja izuma, primjenjiv za vrata sa ležištem lifta sa dva teleskopska krila, tj. sa dva krila koja klize u istom smjeru. Okvir 15 vrata predviđen je za vješanje dva krila 16, 17 koja su prilagođena za pomicanje različitim brzinama pomoću mehanizma koji nije prikazan i koji djeluje iz kabine lifta. Gornji dio sporog krila 16 fiksiran je za poprečnu gredu 18 koja kao i u prethodnom obliku izvođenja, nosi vodeću tračnicu 19 koja ima mogućnost pomicanja s koloturom 20, obrtnim oko osovine fiksirane na okviru 15 vrata. Greda 18 je izvedena s produžetkom u obliku poluge 21, na čijem kraju je smješten kotrljajući kolotur 22 pomičan po vodećoj tračnici 23 koju nosi okvir 15 vrata i nalazi se u istoj ravnini kao i pokretna vodeća tračnica 19. Sa suprotne strane, greda 18 pričvršćena je za sporo krilo 16 koje nosi vodeću tračnicu 24, čija je duljina jednaka zbroju duljina krila 16 i 17 i po kojoj se mogu pomicati koloturi 25, 26 smješteni obrtno na gredi 27 pričvršćenoj na gornjem dijelu brzog krila 17. Brzo krilo 17 nalazi se na izlazu kliznih vrata u produžetku sporog krila 16. Sl. 5 to 8 illustrate another embodiment of the invention, applicable to a door with a lift bed with two telescopic wings, i.e. with two wings that slide in the same direction. The door frame 15 is provided for hanging two wings 16, 17 which are adapted to move at different speeds by means of a mechanism not shown and which operates from the elevator cabin. The upper part of the slow wing 16 is fixed to the transverse beam 18 which, as in the previous form of execution, carries a guide rail 19 which can be moved with a pulley 20, revolving around an axis fixed on the frame 15 of the door. The beam 18 is made with an extension in the form of a lever 21, at the end of which there is a rolling pulley 22 movable along the guide rail 23 carried by the door frame 15 and located in the same plane as the movable guide rail 19. On the opposite side, the beam 18 is attached for the slow wing 16 which carries the guide rail 24, the length of which is equal to the sum of the lengths of the wings 16 and 17 and along which the pulleys 25, 26 can be moved, located rotatably on the beam 27 attached to the upper part of the fast wing 17. The fast wing 17 is located at the exit sliding doors in the extension of the slow wing 16.

Značajna prednost ostvarena zahvaljujući izumu, sastoji se u tome, što u svim slučajevima, ukupna duljina vodeće tračnice za svako od krila, ne prelazi duljinu okvira vrata. Kao rezultat toga, dobivena je znatno bolja konstrukcija vrata. A significant advantage achieved thanks to the invention is that, in all cases, the total length of the guide rail for each of the wings does not exceed the length of the door frame. As a result, a significantly better door construction was obtained.

Iako je izum primjenjiv naročito za vrata s ležištem čiji okvir treba biti fiksiran na zidu s povećanim otvorom, on se odnosi isto tako i na vrata kabine spojena sa srednjim dijelom šasije kabine. U danom slučaju izraz "dvokrilna klizna vrata" odnosi se na vrata pomična u suprotnim smjerovima sa krilima formiranim s dva teleskopska dijela. Although the invention is particularly applicable to doors with a bed whose frame is to be fixed on a wall with an enlarged opening, it also applies to cabin doors connected to the middle part of the cabin chassis. In this case, the term "double sliding door" refers to a door moving in opposite directions with wings formed by two telescopic parts.

Elementi naprijed navedenog izuma, prikazani su u pojednostavljenom obliku. Treba istaknuti da konstrukcija i izvođenje vrata osobnih liftova mogu biti razmatrani u okviru predloženog izuma. To se također odnosi na vodeće tračnice kao elemente za oslanjanje i poprečne grede pridodane krilima ili okviru vrata koje mogu biti realizirane od profilnog lima. Isto tako, neophodno je pričvršćenje između elemenata može se ostvariti bilo kojim načinom povezivanja, prvenstveno zavarivanjem. The elements of the above-mentioned invention are presented in a simplified form. It should be pointed out that the construction and performance of passenger elevator doors can be considered within the scope of the proposed invention. This also applies to guide rails as support elements and cross beams added to the wings or door frame, which can be made of profiled sheet metal. Likewise, the necessary fastening between the elements can be achieved by any method of connection, primarily by welding.
