Definitions

  • the invention relates to a drivable cover for Drainage channels according to the preamble of claim 1.
  • Drainage channels are used in a variety of applications and always used when there is a large drainage of water of an area is required. This can be the case with inclined streets, flat courtyards, parking lots or at gates or passages. If such Drainage channel is used, this must be the case with a large part of the applications can also be driven over, i.e. with a water-permeable one be accessible cover.
  • This cover is usually a grid or grate that completely runs the gutter covered and lies along the edge of the gutter.
  • a cover with a locking device known has a pivotable latch that cuts into an undercut is pivotable within the gutter.
  • the bar is about that centered on the underside of the grid around one to the grid level vertical axis pivotally attached and can be via a Grid-through connector are pivoted until the latch engages in the undercuts.
  • the connector is usually with a screw head equipped with a slot or a suitable polygonal heel has a tool for pivoting the Latch can be attached to the top of the grid. If the latch, however, engages with the undercut generate greater bias of the grille towards the frame is a very large torque on the connector required, often damaging the engaging portions for the tool leads.
  • the construction-related The bar is unloaded, particularly in the case of wide ones Grid a spring action of the bolt, so that the desired fixed connection of the grille to the frame of the channel no longer is guaranteed and the cover when driving over to rattling noises can lead.
  • the invention is that To design the locking device such that the Actuation of the locking bolt by one person applied actuating force takes place, which is essentially is aligned perpendicular to the cover. I.e. that the Locking bolt engaged or disengaged by a push or pull force which is on the engagement mechanism of the locking device attacks.
  • the cover developed according to the invention has a locking device whose locking bolt to cover or Grid plane parallel axis is pivotable. So that can on the one hand achieve a very simple joining movement of the cover, on the other hand, the arrangement of the invention Pivot axis of the locking bolt this very close to the undercut be positioned in the frame so that a large torque when swiveling the locking bolt is safely avoided.
  • the Cover or the grille one near the top of the Grid pivoted lever that extends through the grille extends and carries the locking bolt at its lower end.
  • the locking bolt can be simple pivoting of the lever when the frame is inserted Grid engaged with the undercut in the frame are so that a particularly simple assembly process is achieved is.
  • the lever is also easy to remove the grille pivoted and thus released the grid.
  • the lever for actuating the locking device is preferably provided with a kick tab, which in the loosened Condition of the grille protrudes from the top of the grille.
  • the kick tab is simply depressed and the locking bolt by pivoting the lever in pivoted its locking position. This is for the Assembly of the grid requires no tools, so that a significantly simplified assembly of the grille is achieved.
