• the pin 50 is located outside the guide part 70 and still in the pin guide 90, with the lateral wall sections 92, 94 enclosing the head section 60 of the pin 50 laterally relative to the longitudinal direction 72.
• the pin 50 slides in the guide groove 52 in the direction of the closed end 76 (cf. Fig. 6a ).
• the pin 50 slides with its head section 60 on a sliding surface 154 (see also Figure 3 ) of the tilting bolt 102, whereby the tilting bolt 102 is pivoted in the direction of the release position (cf. Fig. 6a ).
• the tilting bolt 102 snaps back into the locking position due to the spring preload (cf. Figure 6b ).
• the self-locking device 42 In order to be able to close the sash 14 again in the configuration shown, i.e., to pivot it from the partially open position into the closed position, the self-locking device 42 must first be released. In other words, the tilt bolt 102 must be moved from the locked position into the released position. In the proposed sash arrangement 10, this is achieved by moving the handle 38 from the second actuating position (90° position) back into the first actuating position (0° position) (cf. Fig. 7a ). As in Fig. 7a , view bottom left, As shown, the shift rod 46 is then moved back into the Fig.
• the first switching position shown (in the figures “to the right") is moved, in which the rocker latch 102 interacts with the first switching section 140 (surface of the first switching rod section 130, see above) and is thus in the release position.
• the pin 50 can then slide over the rocker latch 102 from its contact with the closed end 76 of the guide groove 52 to the free end 74 of the guide groove (see Fig. 7b ).
• the handle 38 must be moved back into the 90° position (second actuating position) - at least if tumblers are provided - in order to enable, for example, the locking bolts of the tumblers to engage in the corresponding locking receptacles (cf. Fig. 8a ). If the leaf 14 is in the closed position again, the handle 38 can then be moved into the first actuating position (0° position) in order to lock the locking devices (cf. Fig. 8b ).
• the switching rod 46 is in a third switching position corresponding to the third actuating position of the handle 38, in which the switching rod 46 is in relation to the Fig. 5b shown 90° switching position is shifted even further to the left, so that the rocker bolt 102 with its actuating section 120 interacts with the surface of the second switching rod section 132 and is thus in the release position.
• the pin guide 90 is pushed so far into the guide part 70 in this switching position that the pin 50 is located outside the guide part 70 and outside the pin guide 90. If, starting from this configuration, the wing 14 is opened, the guide part 70 and the switching rod 46, which are arranged on the wing 14, are pivoted away from the pivot arm 44, which is arranged on the frame 12 (cf. Fig. 9b ). The sash 14 can thus be pivoted relative to the frame 12 like a conventional pivoting sash.
