Description

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

  The transport rail has a vertical receiving portion and a receiving portion extending substantially horizontally. The horizontal receiving portion is installed in a lower region of the vertical receiving portion at the use position. In the vertical receiving portion, legs that extend substantially horizontally are disposed above the horizontal extending receiving portion and at positions away from both ends of the vertical receiving portion.

  Furthermore, the present invention also relates to a drawer wall portion which is a drawer rear wall including a conveying rail as specifically described, and a drawer including such a drawer wall portion.

  For example, the drawer bottom is connected to the drawer wall by the drawer bottom contacting the horizontal receiving part of the transport rail, or is held or fixed to the connected transport rail, and is held in a tightening relationship with the transport rail by the punched projection. The Conveying rails are also known in the prior art and allow for selective mounting of drawer bottoms of different thicknesses (eg EP 08585753A2, EP0291781A1 and AT389215B).

  FIG. 31 of WO2010 / 046175A2 discloses a transport rail with a lateral receiver for supporting a thinner drawer bottom or as a claw for securing a thicker drawer bottom laterally. The part is pushed laterally into the drawer bottom. These laterally squeezing indents require or can only be done with a relatively great force, or with difficulty in pushing the receiving part laterally into the wood at the bottom of the drawer. Since it is not possible at all, the lateral receptacle may not be excessively thick. However, the lateral receiving portions are not sufficiently thick, and particularly when a large load is applied to the drawer, they may be bent, and the bottom of the drawer may fall off the transport rail. Furthermore, when such a receiving part is used, an undesirable bending of the lateral receiving part may occur even before the drawer bottom part is accurately arranged in advance with respect to the transport rail.

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

  According to the invention, this is achieved by the features of claim 1. Further advantageous embodiments of the invention are described in the dependent claims.

  Therefore, according to the present invention, the horizontally extending leg portion has a protruding portion (protruding portion, abutment projecting) protruding from the leg portion toward the horizontally extending receiving portion.

  In this way, the horizontally extending leg arranged in the vertical receiving part can be used as a support surface for a relatively thin drawer bottom, and the protruding part protruding below the leg is for a thicker drawer bottom. Can be selectively used as a lateral contact surface. In this case, the protruding portion may contact the side surface of the relatively thick drawer bottom portion without pushing the leg portion or the protruding portion laterally into the drawer bottom portion or dropping into the recess of the drawer bottom portion. it can. The fact that the horizontally extending leg does not need to be pushed into the drawer bottom is considerably more robust to the leg or the protruding part placed on it so that the leg or the protruding part can be largely prevented from bending. It means that.

  In one embodiment, the protruding portion of the leg extends substantially parallel to the vertical protruding portion of the transport rail so that the end surface of the relatively thin drawer bottom abuts the vertical receiving portion in surface contact. it can. Therefore, the protruding portion may be substantially L-shaped.

  In a structurally simple variant, the leg part is a punched part (extension part) of the transport rail, in which case the protruding part can be produced by bending the leg part. Or it is also possible to manufacture a leg part and a protrusion part so that it may become a suitable shape of a conveyance rail. Therefore, in this case, the transport rail, the leg portion, and the protruding portion are manufactured from a single metal.

  In one embodiment of the present invention, two or more legs are provided that are spaced apart from each other in the longitudinal direction of the transport rail, the legs projecting downwardly projecting at the use position of the transport rail. Respectively.

  The drawer wall according to the invention, in particular the rear drawer wall, is characterized by the described transport rail. 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.

The transport rail 17 which has not yet been described can be connected to the drawer rail 7, for example, or can be releasably connected thereto, in particular in a form that does not cause damage. The drawers 3 each have a drawer bottom 8 connected to the transport rail 17 as shown in the drawings. The transport rail is connected to, for example, the drawer rear wall 11a and / or the drawer side wall 15 (particularly integrated with it), or can be connected to the drawer rear wall 11a and / or the drawer side wall 15 by a fixing device.

  FIG. 2 is a perspective view of the rail member 10, the drawer bottom 8, and the drawer rear wall 11a. In at least one edge region, the drawer bottom 8 has a stepped groove 9, i.e. open to the edge of the drawer bottom 8, and has a recess that extends over substantially the entire length of the drawer bottom 8. At the mounting position, the groove 9 forms a vertical arrangement part 9a and a horizontal extension part 9b. Thanks to such a shape of the drawer bottom 8, the surface of the drawer bottom 8 can be arranged relatively low and can move closer to the upper edge of the drawer rail 7 (FIG. 1). Therefore, the edge region of the drawer bottom 8 is relatively thin without impairing the stability of the drawer bottom 8 because it is compensated by the rail member 10 even if its strength is locally reduced. The rail member 10 has a first horizontal contact receiving portion 12 for contacting the lower side of the drawer bottom portion 8 and an upper horizontal leg portion 13 for contacting the horizontal portion 9b of the groove 9, and the lower horizontal contact receiving portion.
