Support system for shelves

Abstract

A support system for mounting a shelf to cabinet walls having vertical slots therein. The support system comprises rack rails to insert in the slots, each one of the rack rails comprises a series of upwardly arched channels. The support system further comprises mounting components to mount to the rack rails at similar heights, each one of the mounting components comprising a support face for supporting the shelf, an arched arm to be inserted in the arched channel, and an abutting face to contact one of 1—the rack rails to be mounted thereto and 2—one of the cabinet walls to be mounted thereto through one of the rack rails thereby limiting course of the arched arm in the arched channel. Once the mounting components are mounted to the rack rails, the mounted components provide support faces to set down the shelf thereon.

1 . A kit for installing a shelve to two mounting walls facing each other, the kit comprising:
 a plurality of rack rails,
 each one of the rack rails consisting of an elongated strip having a length, the plurality of rack rails being adapted for being inserted tightly into vertical slots of the mounting walls so to remain tightly inserted between side walls of the slot, each of the rack rails having a front face, a pair of side faces, a rear face, a rail thickness between the side faces thereof, and a depth between the front face thereof and the rear face thereof, 
 each one of the plurality of rack rails comprising arched channels distributed along the length thereof, the arched channels spanning across the thickness of the rack rail, the arched channels extending from an entrance at the front face of the rack rail towards the rear face of the rack rail, the arched channels comprising a top wall and a bottom wall that are each curved around a common center of curvature that is located about the front face upwards relative to the entrance of said channel with the top wall and the bottom wall thereof having a respective radius of curvature, the arched channels having a passage size being the radius of curvature of the bottom wall thereof minus the radius of curvature of the top wall thereof, the arched channel extending exclusively inwardly and upwards from the entrance, the arched channels having at least one of the top wall thereof and the bottom wall thereof extending from the entrance thereof over a first angle of at least 75 degrees, with at least one of the top wall thereof and the bottom wall thereof ceasing to curve around the center of curvature at a second angle of at most 30 degrees relative to the front face of the rack rail; 
   and   a plurality of mounting components,
 each one of the mounting components having an arched arm having sides, an arched top face, an arched bottom face, the arched top face thereof and the arched bottom face thereof curving around a common center of curvature, the arm thereof being adapted to slide tightly into any of the arched channels of any one of the plurality of rack rails with the top face thereof and the bottom face thereof adjoining respectively the top wall and the bottom wall of said arched channel with the sides thereof tight between the walls of the slot, 
 each of the mounting components comprising a body in junction to the arched arm comprising an abutting face adapted to abut the front face of said rack rail distant to the top wall of said channel, and a support face having at least a portion that is perpendicular to the of abutting face. 
   
     
     
         2 . The kit of  claim 1 , wherein at least one of the top wall and the bottom wall of the channels curve around the center of curvature over a third angle of at least 60 degrees. 
     
     
         3 . The kit of  claim 2 , wherein the third angle is at least 75 degrees. 
     
     
         4 . The kit of  claim 1 , wherein at least one of the top wall and the bottom wall of the channels extends about perpendicular to the front face about the entrance of the channels. 
     
     
         5 . The kit of  claim 1 , wherein the second angle is at most 15 degrees. 
     
     
         6 . The kit of  claim 1 , wherein the passage size of the channels is at least 120% compared to a front distance measured between a position where the top wall thereof ceases to curve around the center of curvature and the front wall of the rack rail, wherein the front distance is measured along the radius crossing the position. 
     
     
         7 . The kit of  claim 6 , wherein the passage size is at least 140% compared to the front distance. 
     
     
         8 . The kit of  claim 1 , wherein a minimal distance between the bottom wall and the rear wall of the rack rails measured perpendicular to the front wall thereof is at least 50% of the passage size. 
     
     
         9 . The kit of  claim 8 , wherein the minimal distance is at least 75% of the passage size. 
     
     
         10 . A cabinet comprising two mounting walls each comprising vertical slots, the kit of  claim 1  mounted to the mounting walls of the cabinet, and a shelf laid over the support faces of the mounting components of the kit. 
     
     
         11 . A method of installing a shelf of a cabinet, the method comprising:
 providing opposed mounting walls part of the cabinet, the mounting walls comprising vertical slots facing the opposed one of the mounting walls;   providing the kit of  claim 1 ;   mounting the rack rails of the kit into the slots of the mounting walls;   inserting the arm of the mounting components of the kit into plurality of the channels of the rack rails and rotating the mounting components for the arms to increasingly penetrate the channels until the abutting faces of the mounting components abut against the front face of the rack rails, wherein the support faces of the mounting components provide a leveled area; and   laying down the shelf on the leveled area.
