  • two opposing side rails are attached to the inner walls of the oven muffle, which are used to insert or place food supports (baking trays, baking racks, drip trays, etc.) or also for fastening of telescopic extensions.
  • such side rails in the version mounted as intended on a body wall have at least two vertical grid bars arranged essentially parallel to one another and usually a plurality of essentially horizontally oriented retaining brackets which are attached to the vertical grid bars and connect them.
  • the horizontal holding brackets of the side rails arranged on both sides of the muffle inner walls of an oven are used to place or insert the food carriers, which is why they usually extend from the plane spanned by the vertical grid bars towards the interior of the muffle.
  • the holding brackets have a horizontal section that extends horizontally and essentially straight over the distance between the vertical bars.
  • the horizontal lattice bars For connection to and attachment to the vertical lattice bars, the horizontal lattice bars have essentially vertically angled end sections at their opposite ends, the free ends of which are fixed to the vertical lattice bars, usually welded.
  • pairs of horizontal holding brackets are regularly provided in such side rails, which are arranged one above the other at a small distance which is sufficiently large in order to insert the cooking belt carrier with its side edges between the two horizontal bars, but at the same time is sufficiently small that the food carrier can support itself with a rear section of its side edge against tipping on the upper bracket if it is not completely pulled out of the oven muffle .
  • the bars of such side rails usually consist of a wire with a circular cross-section because this allows for cost-effective production.

  • the receptacles 1j are formed in one piece with the support plate 1d and are formed in a section of the support plate 1d that is folded along the lower edge of the support plate 1d in the direction of the outer rail.
  • Both embodiment variants of the support plates 1d shown in the figures have an end stop 1g at the end located in the insertion direction, which forms a stop against displacement of a carrier placed on the support plate 1d in the insertion direction beyond the end of the support plate 1d located in the insertion direction.
  • the end stop 1g is formed in one piece with the support plate 1d and is designed as a tab bent out of the steel sheet of the support plate perpendicular to the insertion direction.
  • both embodiment variants of the support plate 1d shown in the figures have an end cap 1h at the end located in the pull-out direction, which is designed in one piece with the support plate 1d as a tab bent out of the steel sheet of the support plate in the direction of the movable outer rail and in the assembled state the end of the movable outer rail 1b located in the pull-out direction is at least partially covered.
  • the end cap 1h forms a stop in the pull-out direction for a placed carrier in order to prevent the carrier from being pulled down by the telescopic pull-out 1 when it is pulled out of the oven when the outer rail 1b has reached its final pull-out position.
