V območju med vretenko 4 in čelno letvijo 8 je plosko preko droga 53 in vzvodov 15,44 položena vezna plošča 62. Le-ta je na tistem svojem koncu, kije obrnjen k stranici la ohišja 1, zasnovana z zobom 63, ki prijemlje v ustrezen izrez 64 prvega zapahnilnega droga 65. Na tistem svojem koncu, ki je obrnjen proč od stranice la ohišja 1, je vezna plošča 62 zasnovana z zobom 66, ki prijemlje v izrez 67 drugega zapahnilnega droga 68. Vezna plošča 62 je nadalje preko čepa 14 povezana z vzvodom 15, preko čepa 43 pa z vzvodom 44. V območju vzdolžno nad čepom 59, med drogom 53 in ploščo 62 je razporejen še pritrdilni čep 69. Zapahnilni drog 68 je v območju prehoda zapaha 27 skozenj zasnovan s podolgovato skoznjo luknjo 70, pri čemer je v območju sredine vzdolžne dimenzije luknje 70 zasnovan navznoter zapahnilnega droga 68 obrnjen zob 71, ki sodeluje z blokimim žlebom 30 zapaha 27.In the area between the spindle 4 and the front lath 8, a tie plate 62 is laid flat over the pole 53 and the levers 15,44. The latter is at the end facing the side la of the housing 1, designed with a tooth 63, which grips into a suitable the recess 64 of the first locking rod 65. At its end, facing away from the side la of the housing 1, the connecting plate 62 is designed with a tooth 66 that secures into the recess 67 of the second locking rod 68. The connecting plate 62 is further connected via a pin 14. with lever 15, and via lever 43 with lever 44. In the area longitudinally above the bolt 59, between the pole 53 and the plate 62, a fixing plug 69 is arranged. The locking pole 68 is designed through an elongated through hole 70 through the latch passage 27, at wherein, in the middle of the longitudinal dimension of the hole 70, an inwardly locking tooth 68 is formed, inwardly facing a tooth 71, which cooperates with a block groove 30 of the latch 27.

Naprava po izumu deluje na naslednji način.The device according to the invention operates as follows.

V primeru, da zapahnilna drogova 65, 68 nista zapahnjena (sl. 1), je onemogočeno tudi blokiranje z zapahom 27, kajti zob 71 zapahnilnega droga 68 se nahaja v blokimem žlebu 30 zapaha 27, s čimer je preprečeno premikanje slednjega. Pri odpiranju neprikazanih vrat (sl. 4) se z neprikazano kljuko deluje na vretenko 4 tako, da se slednja zasuče okoli svoje telesne osi v smeri puščice A. Pri tem pritisne odmični bok 10 vzvoda 6 vretenke 4 na potisni drog 53, ki se translatorno premakne proti stranici la ohišja 1, pri čemer hkrati stisne tudi tlačno vzmet 54. S steno luknje 57 pritisne drog 53 na drsni čep 61, ki zasuče potisni kavelj 58 okoli čepa 59, pri čemer prvi, ožji krak kavlja 58 potisne vpad 47 v notranjost ohišja 1. Pri tem napne krak 50 drsnika 46 upogibno vzmet 51. Ko kljuko spustimo, se stisnjena vzmet 54 sprosti, pri čemer deluje preko vzvoda 53 na bok 10 vretenke 4, katero vrne v začetni položaj, prikazan na sl. 1. Upogibna vzmet 61 pa pri tem vrne vpad 47 v njegov izhodiščni položaj.In the case that the locking rods 65, 68 are not locked (Fig. 1), locking by the latch 27 is also prevented, since the tooth 71 of the locking rod 68 is located in the locking groove 30 of the latch 27, which prevents the latter from moving. When opening the non-open door (Fig. 4), the non-shown hook acts on the spindle 4 by rotating the spindle about its body axis in the direction of arrow A. In doing so, it presses the camshaft 10 of the lever 6 of the spindle 4 to the translational pole 53 moves towards the side la of the housing 1, while also compressing the pressure spring 54. With the wall of the hole 57, it presses the rod 53 onto the sliding plug 61, which rotates the thrust hook 58 around the plug 59, wherein the first, narrower hook of the hook 58 pushes the intrusion 47 inside housing 1. In doing so, the arm 50 of the slide 46 is flexed by a spring bending 51. When the hook is lowered, the compressed spring 54 is released, acting through the lever 53 on the side 10 of the spindle 4, which returns to the starting position shown in FIG. 1. The bending spring 61, in doing so, returns the recess 47 to its starting position.

V primeru, da je potrebno vrata blokirati tudi z zapahom 27, se neprikazano kljuko pritisne navzgor, pri čemer se vretenka 4 zasuče okoli svoje telesne osi v smeri puščice B (sl. 5). Vzvod 15 se pri tem odkotali po odmični ploskvi 13 izbokline 9 na vzvodu 6 vretenke 4, pri čemer se preko slednjega in čepa 14 premakne vezna plošča 62. Ker je le-ta s svojim prvim zobom 63 v prijemu s prvim zapahnilnim drogom 65, povleče slednjega navzdol, tj. v smeri proti vpadu 47, s čimer so neprikazana vrata blokirana na svoji zgornji strani. Vezna plošča 62 pa je s svojim drugim zobom 66 v prijemu z zapahnilnim drogom 68, katerega potisne navzdol, tj. v smeri proč od vretenke 4. S premaknitvijo droga 68 pride tudi zob 71 iz prijema z žlebom 30 zapaha 27, s čimer je omogočeno, da se preko potisne brade 35 cilindrične ključavnice 34 deluje na krivuljasto ploskev 31 zapaha 27. S tem se slednjega premakne v blokirni položaj. V tem, z zapahom 27 blokiranem položaju, je onemogočeno premikanje zapahnilnih drogov 65, 68, kajti v primeru, da se vretenko 4 s pomočjo kljuke poskuša premakniti v smeri nasproti puščici B, prepreči na zapah 27 nalegajoč zob 71 zapahnilnega droga 68 premik vezne plošče 62 in s tem zapahnilnih drogov 65,86.In the event that the door also needs to be locked by a latch 27, the unhooked hook is pressed upwards, with the spindle 4 rotating about its body axis in the direction of arrow B (Fig. 5). The lever 15 is then rolled up on the cavity 13 of the projection 9 at the lever 6 of the vertebra 4, and the connecting plate 62 moves over the latter and the stud 14. As it is pulled into the first locking rod 65 by its first tooth 63, it is pulled. the latter down, i.e. in the direction of intrusion 47, thereby blocking the non-displayed door on its upper side. The connecting plate 62, with its second tooth 66, is in the grip with the locking rod 68, which it pushes down, ie. away from the spindle 4. By moving the bar 68, the tooth 71 also comes out of the grip with the groove 30 of the latch 27, thereby allowing the cylindrical lock 34 to act on the curved surface 31 of the latch 27. This moves the latter. into the blocking position. In this locked position 27, the locking rod 65, 68 is prevented from moving, because if the spindle 4 tries to move in the opposite direction to the arrow B, the locking tooth 71 of the locking rod 68 prevents movement of the connecting plate 62 and thus locking rods 65.86.
