  • Locking element 21 protrude from the second rail 13 upwards.
  • the two stop surfaces 37a, 37b are spaced apart in the longitudinal direction (L) of the second rail 13 and extend substantially perpendicular to the longitudinal direction (L) of the second rail 13.
  • the locking element 21 of the second rail 13 is counteracted by its cooperation with the first projection 24a against its resilient action bent down (Fig. 10b). If the first rail 12 of the drawer 3 is pushed further in the closing direction, the front panel 5 of the drawer 3 strikes against the front side 2 a of the furniture carcass 2 and thus can not be moved further in the closing direction (FIG. 10 c). However, it can also be seen in FIG. 10c that the locking element 21 of the second rail 13 is not properly locked to the second projection 24b of the first rail 12 because the second projection 24b comes to rest directly on the locking element 21.
  • a faulty locking between the rails 12, 13 but can by a continued movement of the Drawer 3 can not be corrected in the closing direction, because the front panel 5 rests against the end face 2a of the furniture body 2 and thus a further movement of the drawer 3 is prevented in the closing direction.
  • a faulty locking between the rails 12, 13 would also result in the drawer 3 remaining in an open position in an undesired manner.
  • first the drawer 3 (and thus the first rail 12) is pulled in the extension direction (A) (see FIG. 11 a), wherein the first rail 12, for example the second projection 24 b of FIG first rail 12, with the second stop surface 37b of the locking element 21 can be coupled. Due to the interaction of the rail 12 with the second stop surface 37b of the locking element 21, the second rail 12 can be pulled from a complete closed position into an open position.
