Abstract

A drawer runner system is provided, as well as a chest of drawers including the drawer runner system. The drawer runner system includes a rail having a mounting plate, a top engagement portion, and a bottom engagement portion. The top and bottom engagement portions are extending in parallel along the rail. The drawer runner system further includes a runner member having a top sliding surface for sliding engagement with the top engagement portion and a bottom sliding surface for sliding engagement with the bottom engagement portion. The lateral width of at least one of the top sliding surface or the bottom sliding surface is greater than the lateral width of the corresponding top engagement portion or bottom engagement portion, respectively.

Claims

exact text as granted — not AI-modified
1 . A drawer runner system, comprising:
 a rail having a mounting plate;   a top engagement portion and a bottom engagement portion, the top and bottom engagement portions extending in parallel along the rail; and   a runner member having a top sliding surface for sliding engagement with the top engagement portion and a bottom sliding surface for sliding engagement with the bottom engagement portion,   wherein a lateral width of at least one of the top sliding surface or the bottom sliding surface is greater than a lateral width of the corresponding top engagement portion or bottom engagement portion, respectively.   
     
     
         2 . The drawer runner system according to  claim 1 , wherein the top and bottom engagement portions are vertically aligned. 
     
     
         3 . The drawer runner system according to  claim 1 ,
 wherein the lateral width of the top sliding surface is greater than the lateral width of the top engagement portion, and   wherein the lateral width of the bottom sliding surface is greater than the lateral width of the bottom engagement portion.   
     
     
         4 . The drawer runner system according to  claim 1 , wherein at least one of the top or bottom engagement portions is provided with a radius. 
     
     
         5 . The drawer runner system according to  claim 1 , wherein the lateral width of at least one of the top or bottom engagement portions is 1 mm or less. 
     
     
         6 . The drawer runner system according to  claim 1 , wherein the rail comprises a top flange extending downwards, and an upper lip extending upwards from the top flange, wherein an interface between the top flange and the upper lip forms the top engagement portion. 
     
     
         7 . The drawer runner system according to  claim 1 , wherein the rail comprises a bottom flange extending upwards, and a bottom lip extending downwards from the bottom flange, wherein an interface between the bottom flange and the bottom lip forms the bottom engagement portion. 
     
     
         8 . The drawer runner system according to  claim 1 , wherein the mounting plate, the top engagement portion, and the bottom engagement portion are integrally formed. 
     
     
         9 . The drawer runner system according to  claim 1 , wherein a first lateral distance between the mounting plate and the top and bottom engagement portions is greater than a second lateral width of the runner member times 0.5. 
     
     
         10 . The drawer runner system according to  claim 1 , wherein the runner member is capable of being turned in relation to a drawer side wall. 
     
     
         11 . The drawer runner system according to  claim 1 , wherein the runner member is made of plastic. 
     
     
         12 . The drawer runner system according to  claim 1 , wherein the rail is made of metal. 
     
     
         13 . The drawer runner system according to  claim 1 , wherein the runner member has a shape of a polygon or a shape of a cylinder. 
     
     
         14 . The drawer runner system according to  claim 1 , wherein at least one of the top sliding surface or the bottom sliding surface is at least partly concave. 
     
     
         15 . The drawer runner system according to  claim 1 , wherein at least one of the top sliding surface or the bottom sliding surface comprises an outer end wing, an inner end wing, and a central sliding portion extending from the outer end wing, wherein a vertical distance between an outer edge of the top sliding surface and an outer edge of the bottom sliding surface is larger than a vertical opening distance between the top and bottom engagement portions, thereby preventing the runner member from being laterally displaced out of the rail. 
     
     
         16 . The drawer runner system according to  claim 15 , wherein the central sliding portion is at least partly provided with a radius. 
     
     
         17 . The drawer runner system according to  claim 16 , wherein the radius of the central sliding portion of the top sliding surface is equal to or greater than a radius of the top engagement portion, and/or the radius of the central sliding portion of the bottom sliding surface is equal to or greater than a radius of the bottom engagement portion. 
     
     
         18 . The drawer runner system according to  claim 15 , wherein the central sliding portion has a horizontal portion, the horizontal portion being arranged as an intermediate portion between two portions provided with a radius. 
     
     
         19 . The drawer runner system according to  claim 1 , wherein the rail comprises a horizontal front section, an intermediate retardation section being tilted vertically upwards, and a rear section being tilted vertically downwards. 
     
     
         20 . The drawer runner system according to  claim 1 , wherein a total width of the drawer runner system is less than 14 mm. 
     
     
         21 . A chest of drawers comprising a cabinet, at least one drawer, and at least one drawer runner system, the at least one drawer runner system comprising:
 a rail having a mounting plate;   a top engagement portion and a bottom engagement portion, the top and bottom engagement portions extending in parallel along the rail; and   a runner member having a top sliding surface for sliding engagement with the top engagement portion and a bottom sliding surface for sliding engagement with the bottom engagement portion,   wherein a lateral width of at least one of the top sliding surface or the bottom sliding surface is greater than a lateral width of the corresponding top engagement portion or bottom engagement portion, respectively.   
     
     
         22 . The drawer runner system according to  claim 4 , wherein the radius is in a first range of 0.5 mm-5.0 mm, in a second range of 0.7 mm-4.0 mm, in a third range of 0.8 mm-3.0 mm, or in a fourth range of 1.0 mm-2.5 mm.
