Description

Izum se odnosi na uređaj za blokiranje vratnih krila po uvodnom dijelu prvog patentnog zahtjeva. The invention relates to a device for blocking door wings according to the introductory part of the first patent claim.

Uređaj takve vrste za blokiranje je već poznat (pogledaj na primjer prospekt tvrtke G.U. SECURY, SRNj), kod kojeg vodi kućište uređaja preko vretena protusmjerno pokretna zasunska motka i kod koje je vreteno preko trna povezano s kvakom. Navedeni uređaj nije pogodan za blokiranje naročito vratnih krila, obuhvaćajući nosive okvire iz na primjer uskih Al ili plastičnih profila, pošto je iz sigurnosnih razloga potrebno vrata blokirati također s zasunom pomoću ključa, a što kod navedenog uređaja nije moguće. A blocking device of this type is already known (see, for example, the prospectus of the company G.U. SECURY, SRNj), in which the housing of the device is guided by a counter-moving latch rod over the spindle and in which the spindle is connected to the handle via a mandrel. The mentioned device is not suitable for locking door leaves in particular, including load-bearing frames made of, for example, narrow Al or plastic profiles, since for safety reasons it is necessary to lock the door also with a latch using a key, which is not possible with the mentioned device.

Zadatak izuma je također ostvariti napravu za blokiranje vratnih krila, kod kojih će biti moguće navedena krila, obuhvaćajući nosive okvire, blokirati također i zasunom, na kojeg se djeluje ključem, kod čega se hod zasunske motke ne smije promijeniti. The task of the invention is also to realize a device for blocking the door leaves, where it will be possible to block said leaves, including the load-bearing frames, also with a latch, which is operated with a key, in which case the stroke of the latch rod must not be changed.

Taj zadatak je riješen po izumu s karakteristikama, datim u karakterističnom dijelu prvog patentnog zahtjeva. This task is solved by the invention with the characteristics given in the characteristic part of the first patent claim.

U području stranice 1c i iznad poprečne simetrale vretena 4 je uz stijenku 1c klizno pomično postavljen potiskivač 37, vođen s vodilicom 38, koja se na suprotnom kraju završava sa stopalastim osloncem 39. Između posljednjeg i potiskivača 37 je postavljena tlačna opruga 40, čiji oslonac 39 pritišće na stabilni čep 41, oslonac 37 se upire na izdanak 7 vretena 4. Simetrično na navedenu simetralu vretena 4 je postavljenom čepu 16 analogan pričvrsni čep 42. U uzdužnoj simetrali čepa 14 je u uzdužnom smjeru prema stranici 1a postavljena na čepu 43 okretno uležištena poluga 44, koja se povezuje s valjkastim tijelom vretena 4 i odmičnom plohom 12 izbočine 9. Uzdužnoj simetrali vretena 4 i uzdužno iznad čepa 42 je na kućištu 1 postavljen stabilan čep 45, koji služi kao vodilica klizaču 46 zasuna 47. Navedeni je translatorno i u poprečnom smjeru kućišta 1 vođen u pobliže neprikazanom izrezu čelne letve 8, kroz koju izlazi zasun 47, koji je vijkom 48 povezan na prvi, okomito na klizač 46 postavljen krak 49. Klizač 46 je na istoj strani, koja je okrenuta suprotno od zasuna 47, izveden sa sljedećim, okomito na klizač 46 postavljenim krakom 50. On je povezan s prvim krajem savitljive opruge 51, kod čega je njen drugi kraj namotan na pričvrsni čep 52, koji je postavljen na kućište 1. Na klizaču 46 zasuna 47 je plošno položena pločasto potisna motka 53, koja svojim prvim krajem djeluje na odmični bok 10 vretena 4. Na drugom kraju motke 53 je postavljena tlačna opruga 54, koja je svojim suprotnim krajem oslonjena na opružni naslon 55, pritisnut na stijenku 1a kućišta 1. Opruga 54 pritišće na stepenicu 56 navedene poluge 53 na čepu 45, koja služi kao graničnik pomaka motke 53. U području učvršćenja opruge 54 na motku 53 je navedena izvedena s uzdužnim prolaznim provrtom 57, usmjeren u uzdužni smjer motke 53. U prostoru između kućišta 1 i motke 53 te uzdužno iznad zasuna 47 je postavljena dvokraka potisna kuka 58, koja je okretno uležištena na čep 59 (sl. 5). Prvi, uži krak kuke 58 je povezan s izrezom 60 klizača 46, drugi, širi krak kuke 58 preko na njemu postavljenog kliznog čepa 61 povezan je s provrtom 57 poluge 53. In the area of the side 1c and above the transverse bisector of the spindle 4, a pusher 37 is slidably mounted against the wall 1c, guided by a guide 38, which ends at the opposite end with a foot support 39. it presses on the stable plug 41, the support 37 is pointed at the projection 7 of the spindle 4. Symmetrically on the indicated bisector of the spindle 4, there is an analogous fastening plug 42 placed on the plug 16. In the longitudinal bisector of the plug 14, in the longitudinal direction towards page 1a, a rotatably mounted lever is placed on the plug 43 44, which is connected to the cylindrical body of the spindle 4 and the offset surface 12 of the protrusion 9. A stable plug 45 is placed on the housing 1 at the longitudinal bisector of the spindle 4 and longitudinally above the plug 42, which serves as a guide for the slide 46 of the latch 47. It is indicated translationally and in the transverse direction housing 1 is guided in the cut-out of the front slat 8, not shown in detail, through which the latch 47 exits, which is connected to the first, perpendicular to the slide 46, by means of a screw 48 en arm 49. The slider 46 is on the same side, which is facing the opposite of the latch 47, made with the next, perpendicular to the slider 46 placed arm 50. It is connected to the first end of the flexible spring 51, where its second end is wound on the fastening plug 52, which is placed on the housing 1. On the slide 46 of the latch 47, a plate-like pressure rod 53 is laid flat, the first end of which acts on the offset side 10 of the spindle 4. At the other end of the rod 53, a compression spring 54 is placed, which end rests on the spring support 55, pressed on the wall 1a of the housing 1. The spring 54 presses on the step 56 of the mentioned lever 53 on the cap 45, which serves as a limiter for the movement of the pole 53. In the area of the fastening of the spring 54 on the pole 53, it is designed with a longitudinal through hole 57, directed in the longitudinal direction of the pole 53. In the space between the housing 1 and the pole 53 and longitudinally above the latch 47, a two-pronged pressure hook 58 is placed, which is rotatably mounted on the plug 59 (fig. 5). The first, narrower arm of the hook 58 is connected to the cut-out 60 of the slider 46, the second, wider arm of the hook 58 is connected to the bore 57 of the lever 53 via the sliding plug 61 placed on it.

U području između vretena 4 i čelne letve 8 je ploštimice preko poluge 53 i poluga 15, 44 položena vezna ploča 62. Ona je na svom kraju, koji je okrenut k stranici 1a kućišta 1, izveden sa zubom 63, koji prianja u odgovarajući izrez 64 prvog zatvarača poluge 65. Na tom svom kraju, koji je okrenut suprotno od stranice 1a kućišta 1, je vezna ploča 62 izvedena sa zubom 66, koji zahvaća u izrez 67 drugog zatvarača poluge 68. Vezna ploča 62 je nadalje preko čepa 14 povezana s polugom 15, preko čepa 43 pa s polugom 44. U području uzdužno iznad čepa 59, između poluge 53 i ploče 62 je postavljen i pričvrsni čep 69. Zatvarač poluge 68 je u području prolaza zasuna 27 kroz njega izveden s uzdužnim prolaznim provrtom 70, kod čega je u području sredine uzdužne dimenzije provrta 70 izveden unutar zatvarača poluge 68 okretni zub 71, koji djeluje s blokirnim žlijebom 30 zasuna 27. In the area between the spindle 4 and the front bar 8, a connecting plate 62 is laid flat over the lever 53 and the levers 15, 44. At its end, which faces the side 1a of the housing 1, it is designed with a tooth 63, which fits into the corresponding cut-out 64 of the first lever closure 65. At its end, which is facing the opposite side of the side 1a of the housing 1, the connecting plate 62 is made with a tooth 66, which engages in the cut-out 67 of the second lever closure 68. The connecting plate 62 is further connected to the lever via the plug 14 15, over the plug 43 and with the lever 44. In the area longitudinally above the plug 59, between the lever 53 and the plate 62, a fastening plug 69 is placed. in the area of the middle of the longitudinal dimension of the hole 70, a rotating tooth 71, which interacts with the blocking groove 30 of the latch 27, is made inside the closure of the lever 68.

Uređaj po izumu djeluje na sljedeći način. The device according to the invention works in the following way.

U primjeru, da poluga 65, 68 nije zatvorena (sl. 1) onemogućeno je blokiranje sa zasunom 27, pošto se zub 71 poluge 68 nalazi u blokirnom žlijebu 30 zasuna 27, čime je onemogućeno njegovo pomicanje. Kod otvaranja neprikazanih vrata (sl. 4) s neprikazanom kvakom se djeluje na vreteno 4 tako, da ga ona zakrene oko njegove osi u smjeru strelice A. Kod toga pritisne odmični blok 10 poluge 6 vretena 4 na potisnu polugu 53, koja se translatorno pomakne prema stranici 1a kućišta 1, kod čega istovremeno stisne tlačnu oprugu 54. Sa stijenke provrta 57 pritisne poluga 53 na klizni čep 61, koji zakrene potisnu kuku 58 oko čepa 59, kod čega prvi, uži krak kuke 58 potisne zasun 47 u unutrašnjost kućišta 1. Kod toga napne krak 50 klizača 46 savitljive opruge 51. Ako kvaku spustimo, stisnuta opruga 54 se spusti, kod čega djeluje preko poluge 53 na bok 10 vretena 4, kojega vrati u početni položaj, prikazan na slici 1. Savitljiva opruga 51 kod toga vrati zasun 47 u njegov početni položaj. In the example, if the lever 65, 68 is not closed (fig. 1), blocking with the latch 27 is disabled, since the tooth 71 of the lever 68 is located in the blocking groove 30 of the latch 27, which prevents its movement. When opening a door not shown (fig. 4) with a handle not shown, the spindle 4 is acted upon so that it rotates around its axis in the direction of arrow A. In doing so, the displacement block 10 of the lever 6 of the spindle 4 is pressed against the push lever 53, which moves translationally. towards the side 1a of the casing 1, at the same time compressing the compression spring 54. From the wall of the bore 57, the lever 53 presses on the sliding plug 61, which rotates the pressure hook 58 around the plug 59, whereupon the first, narrow arm of the hook 58 pushes the latch 47 into the interior of the casing 1 In this case, the tension arm 50 of the slider 46 of the flexible spring 51. If we lower the handle, the compressed spring 54 is lowered, in which case it acts via the lever 53 on the side 10 of the spindle 4, which it returns to the initial position, shown in Figure 1. The flexible spring 51 in this case return the latch 47 to its initial position.

U primjeru, kada je potrebno vrata blokirati također sa zasunom 27, neprikazana kvaka se pritisne nagore, kod čega se vreteno 4 zakrene oko svoje osi u smjeru strelice B (sl. 5). Poluga 15 se kod toga pomakne po odmičnoj plohi 13 izbočine 9 na poluzi 6 vretena 4, kod čega se preko njih i čepa 14 pomakne vezna ploča 62. In the example, when it is necessary to block the door also with the latch 27, the latch (not shown) is pressed upwards, during which the spindle 4 rotates around its axis in the direction of arrow B (fig. 5). In this case, the lever 15 is moved along the displacement surface 13 of the protrusion 9 on the lever 6 of the spindle 4, whereupon the connecting plate 62 is moved over them and the plug 14.

Kako je ona sa svojim prvim zubom 63 u dodiru s prvom zasunskom polugom 65, povuče je nadolje, tj. u smjeru suprotno prodoru 47, čime su neprikazana vrata blokirana na svojoj gornjoj strani. Vezna ploča 62 sa svojim drugim zubom 66 u dodiru sa zasunskom polugom 68, koju pritisne prema dolje, tj. u smjeru suprotnom od vretena 4. S pomicanjem poluge 68 dođe također zub 71 izvan dodira sa žlijebom 30 zasuna 27, čime je omogućeno da se preko pritisnog izdanka 35 cilindrične brave 34 djeluje na krivuljnu plohu 31 zasuna 27. S time se svaki pomakne u blokirani položaj. As it is in contact with the first latch lever 65 with its first tooth 63, it pulls it down, i.e. in the direction opposite to the penetration 47, whereby the door (not shown) is blocked on its upper side. The connecting plate 62 with its second tooth 66 is in contact with the latch lever 68, which it presses down, i.e. in the direction opposite to the spindle 4. With the movement of the lever 68, the tooth 71 also comes out of contact with the groove 30 of the latch 27, which makes it possible to via the pressure protrusion 35 of the cylindrical lock 34 acts on the curved surface 31 of the latch 27. With this, each moves to the locked position.

U tom, blokirnom položaju sa zasunom 27, je onemogućeno pomicanje zasunskih poluga 65, 68, kao u primjeru, da se vreteno 4 s pomoću kvake pokuša pomaknuti u suprotan smjer od strelice B, zapreći na zasun 27 naliježući zub 71 zasunske poluge 68 pomak vezne ploče 62 i s tim zasunskih poluga 65, 68. In this blocking position with the latch 27, the movement of the latch levers 65, 68 is disabled, as in the example, if the spindle 4 tries to move in the opposite direction from arrow B with the help of the handle, the tooth 71 of the latch lever 68 touching the latch 27 prevents the movement of the connection plate 62 and with it latch levers 65, 68.
