  • the support frame 4 is connected in normal operation with the extension system, the drawer / support frame composite (telescopic drawer) is preferably easy to insert into each plane of the side Einitatigitter and latched securely, as will be described in more detail below.
  • FIG. 3 shows the Gargutlinisystem 1 from FIG. 1 , in which now the extraction system / support frame composite of telescopic rails 3 and support frame 4 is separated from the suspension grille 2. At their rear end region, the respective telescopic rail 3 in each case has a supporting angle 16.
  • FIG. 4 shows the Gargutierisystem 1 from FIG. 3 enlarged in the region of a support bracket 16.
  • the telescopic rail 3 has an elongated suspension element 18 for suspension on the rod 7 of the hook-in grid 2.
  • the suspension element 18 is considered to be configured by the telescopic rail 3 upwardly extending sheet metal, which is bent in a U-shape in the direction of the rod 7 out.
  • the suspension element 18 is arranged so that it can rest or be suspended on the rod 7 while permitting a relative displacement or slippage, and thus hold the composite of the telescopic rail 3 and the support frame 4 on the suspension grid 2.
  • the plateau region 20 lies at least at its rear end at least by a vertical distance (in the x direction) lower than the vertex of the U-shaped suspension element 18 or suspension element region, which is at least the height (in the x direction) of the transverse section 9 of the rod 7 equivalent.
  • the plateau region 20 is removed by the value of the height of the transverse portion 9 from the (inner) apex of the U-shaped suspension member 18, or more.
  • a stop in the form of a spring 21 is attached, which is at least partially less than the height of the transverse portion 9 from the (inner) vertex of the suspension member 18 is removed.
  • the suspension element 18 does not reach all the way to the rear end of the telescopic rod 3, where the sheet is designed rather than the support bracket 16.
  • the support bracket 16 is formed as a right angle to the outside angled sheet, the altitude (corresponding to the x-coordinate) of the lateral buckling fold corresponds to the apex of the suspension element 18.
  • the support bracket 16 is bent at a projecting rearward over the telescopic rail 3 area down.
  • the support bracket 16 has an upper support area 22 which is located at the level of the apex of the suspension element 18 and a sliding area 23 which is offset downwards.
  • the sliding area 23 is at least as deep as the plateau area 20.
  • the suspension element 18 is so narrow that it does not or only just touches a vertical strut 24 of the hanging grid.
  • the sliding portion 23 When inserting the extension system 3 in a cooking chamber, the sliding portion 23 is first placed on the rod. Since the suspension member 18 is sufficiently narrow, it slides past the vertical strut 24 upon insertion. Especially if the sliding region 23 is lower than the plateau region 20, the extension system 3 slides in the rear only on the back, which allows a relatively easy insertion.
  • the U-shaped suspension member 18 is arranged so that, when the sliding portion 23 slides on the longitudinal portion 8, it is located with the corresponding length above the longitudinal portion 8 of the rod 7.
  • FIG. 5 shows the Gargutlinisystem 1 in a state in which the telescopic rail 3 and the associated support frame 4 are inserted so far into the suspension grid 2, that the sliding portion rests on the rear cross section. In this position, there is already a predominant part of the suspension element 18 above the rod. 7
  • FIG. 6 shows the Gargutlinisystem 1 fragmentary in a state in which the extension system 3 is already inserted so far that the sliding portion 23 and the angled portion between the sliding portion 23 and the support portion 22 slid behind the rear cross section 9.
  • the longitudinal section 8 of the rod 7 now rests on the support region 22 and on the suspension element 18 as shown.
  • the drawer system 3 is not yet fully inserted, so that the plateau region 20 is still in front of the rear transverse section 9.
  • FIG. 8 shows the Gargut lymph system 1 in the fully inserted state in the front area.
  • the suspension element 18 has a forwardly projecting latching area 25 in the form of an upwardly angled sheet.
  • the front area can fall down by its weight or be pressed by the user, that the latching portion 25 engages the front cross section 9 of the rod and holds there.
  • the front area of the extension system / carrier frame composite is secured against accidental lifting or jumping out.
  • the latching by the user can be easily solved by appropriate application of force again and so the pull-out system / carrier frame composite remove by pulling out the suspension grille 2, z. B. for a pyrolysis or for insertion into another oven level.
  • FIG. 8 further shows a screw in which the front attachment of the support frame 4, a vertically upstanding, welded to the telescopic rail 3 threaded bolt 26 is guided through the through hole 15 of the support frame 4 and tightened by a matching knurled nut 27.
  • FIG. 9 shows the pullout system / carrier frame composite from behind with a view of the rearwardly directed slot 14 of the support frame 4, in which for attachment to the pullout system 3 directed in the direction of the support frame 4, welded pin 28 of the telescopic rail 3 is inserted.
  • FIG. 9 also shows a Radienaussteififung 29 between a side support frame portion 12 and the front support frame portion 11 for further improving the rigidity of the support frame 4th
  • the lateral support frame sections 12 projects beyond the respective associated telescopic rail 3 upwards, so that this against contamination, for. B. fat splash, is better protected.
  • the pull-out system can also be self-supporting; z. B. as two telescopic rails, which are connected by means of a scaffold.
