  • An end portion 326 is outside of the slide / clip portion 228 provided with a projection 330, which during the movement of the flat bar can be in contact with a control curve along its movement path.
  • lug 330 with the curve becomes the lug from the standby (shown with solid lines) in the operating position (indicated by dashed lines) moves, which moves and holds part 322 in the locked position, until an opening in the control curve swivels the approach back to its starting position allows.
  • the outer dimension of the flange 342 is smaller than the distance Mx (FIG. 7), so that the element 300 can be easily inserted between the strips 230.
  • the length of the bolt 344 is the diameter of the outer dimension of the flange 340 equal.
  • the width W (FIG. 28) of the bar 344 is somewhat smaller than the width A. (Fig. 5) from slot 308 (Fig. 20) between adjacent beams 208,210. If therefore, the latch 344 is aligned in the longitudinal direction of the slot 308, the Bars are inserted between the bars 208,210 of a pair of bars and This will prevent these bars from approaching until the latch is removed becomes.
  • the depth D of the latch 344 is preferably somewhat less than the height H (FIG. 5) the bar 208,210.
  • the handle 340 consists of a button-like head section 346 and a handle 348 Tool can be inserted between the head section 346 and the flange 342 to remove the locking member 300 from a shoe / bracket 228 (Fig. 7) to facilitate.
  • the length of the stem 348 is chosen such that the head section 346 does not protrude from the shoe.
  • the slide shoe is preferably with a Sliding layer, e.g. provided according to DE 19834893.
  • element 300 is further in the position shown (with the Handle 340 above). However, it becomes clear from the preceding description element 300 must operate with the handle below in operation.
  • Each side surface of latch 344 is preferably with an upper groove 350 and one provided lower groove 352.
  • they are opposite side surfaces of the beams 208,210 formed with beads, which in Locking state can snap into a groove 350 or 352.
  • the beam 208 has a lower bead 356 to cooperate with a groove 352.
  • the beam 210 an upper bead 358 for cooperation with the other groove 350.
  • the distance Aw (Fig. 29) between the beads 356, 358 is smaller than the width W of the bar, so that when the beads snap into place, a snap connection between the locking element 300 and the pair of bars 208,210 comes about and jump out of Bumps can be avoided.
  • latch 344 takes place with ridges with grooves and the beams 208,210 could be provided with grooves instead of beads.
  • the distance D * (Fig. 26) between the lower grooves 352 and the underside of the flange 342 is greater than the distance H * (FIG. 29) between the lower bead 356 and the end faces 362 of the beams. It therefore remains in the locked state a narrow gap ⁇ between the flange 342 (not shown in FIG. 29) and the end faces 362 free so that the lock engages securely and not on surface 362 gets up.
