Description

  The present invention relates to a transport rail for a drawer bottom.

  The rail includes two receiving portions that extend substantially perpendicular to each other and are connected by a stepped portion, the stepped portion having a horizontal receiving portion and a vertical receiving portion connected thereto.

Furthermore, the present invention relates to a drawer wall portion which is a drawer side wall in particular, and the drawer wall portion includes a transport rail as described below and a drawer including such a drawer wall portion.

  In order to fix the drawer bottom, the drawer wall in the shape of a hollow chamber (chamber) manufactured from a metal protruding member or metal member is supported and / or fixed by the lateral edge area of the drawer bottom Having a transport rail. For this purpose, the transport rail has a punched fixing means in the form of a protrusion, whereby the drawer bottom can be fixed in a clamped state with respect to the transport rail. Conveying rails are also known in the prior art and selectively allow the mounting of drawer bottoms of different thicknesses.

  An example of fixing the drawer bottoms of different thicknesses to the transport rail is shown in FIGS. 35 to 37 of WO2010 / 046175 A2. In this case, the thickness of the plate-shaped drawer bottom is constant, and even when the drawer is in a relatively large load state, the thickness of the drawer bottom is relatively thick in order to prevent the drawer bottom from being broken. The disadvantage in this case is that the drawer bottom, which is relatively large because of its thickness, reduces the height of the storage space and thus the volume of the drawer.

The object of the present invention is therefore to provide a general transport rail as described in the initial part of the specification, which can avoid the above-mentioned drawbacks.

According to the invention, this object is achieved by the features of claim 1. Further advantageous forms are set out in the dependent claims.

  According to the present invention, there are at least one tab (knob, claw) that can be bent on the drawer bottom side, since at least one of the receiving parts fixes the drawer bottom part. Have.

  In this way, at least one of the receiving parts and the transport rails arranged in the stepped part can thereby have a drawer bottom with different thicknesses and a drawer bottom with stepped grooves (acting force) in a locking relationship (force -Locking relationship) to have tabs that are selectively fixed to the transport rail.

  The transport rail is suitable for fixing the first drawer bottom having a constant thickness. For this purpose, at least one tab is arranged in the mounting state in a horizontally extending receiving part of the transport rail, and the tab is pressed under the drawer bottom.

  In addition, this transport rail is thicker than the first drawer bottom and is suitable for fixing the bottom to a second drawer having a stepped groove in its edge region, i.e. a recess open on the edge of the drawer bottom. Yes. The height of the drawer storage space is increased by providing such a drawer bottom. For example, the lateral groove of the drawer bottom is 8 mm, and the upper side of the drawer bottom is also lowered by 8 mm compared to the conventional one, thereby increasing the storage space height by 8 mm.

  The drawer wall according to the invention (especially the side wall of the drawer) is characterized by a transport rail as described. The drawer according to the invention has at least one such drawer wall.

  Further details and advantages of the invention are illustrated by the examples shown in the drawings.
