Rail or telescopic extension

Abstract

A horizontal or vertical rail or telescopic extension of a cupboard element, a baking shelf or an oven door of a cooking or similar device. The extensions including at least one outer rail of bent sheet metal and a sliding rail of bent sheet metal, which partially surrounds the outer rail and can be displaced along the outer rail by an anti-friction bearing. The rail extension including an outer attachment rail which is connected to and reinforces the outer rail and/or a further attachment rail that is connected to and reinforces the sliding rail. The telescopic extension includes two interconnected rail extensions.

       17 . A rail extension for the horizontal or vertical extension of an element such as a cupboard element, a baking shelf or an oven door of a cooking appliance or similar device, the extension comprising: 
 at least one outer rail of bent sheet metal;    a sliding rail of bent sheet metal that partially surrounds said outer rail;    an anti-friction bearing by which said sliding rail can be displace along said outer rail; and    an outer attachment rail connected to and reinforcing at least one of said outer rail or an attachment rail connected to said sliding rail.    
   
   
       18 . The rail extension according to  claim 17 , including said outer rail and said sliding rail each having a pair of legs and said anti-friction bearing includes at least one rolling element which slides between one of said legs of each pair of legs of said outer rail and said sliding rail for mutual guidance of said outer rail and said sliding rail.  
   
   
       19 . The rail extension according to  claim 18 , including said rolling element formed by a plurality of cage-mounted balls, roll or rollers.  
   
   
       20 . The rail extension according to  claim 17 , including said outer rail has a U-shaped profile.  
   
   
       21 . The rail extension according to  claim 17 , including said outer attachment rail has a U-shaped profile.  
   
   
       22 . The rail extension according to  claim 17 , including said outer rail is connected to said outer attachment rail by at least one of welding, riveting, screwing or gluing.  
   
   
       23 . The rail extension according to  claim 17 , including said outer rail is formed with a closed hollow profile.  
   
   
       24 . The rail extension according to  claim 23 , including said outer rail is formed with a D-shaped profile.  
   
   
       25 . The rail extension according to  claim 17 , including said sliding rail and said attachment rail are formed with a U-shaped profile.  
   
   
       26 . The rail extension according to  claim 17 , including said sliding rail is connected to said attachment rail by at least one of welding, riveting, screwing or gluing.  
   
   
       27 . The rail extension according to  claim 17 , including the horizontal or vertical extension element has a pair of longitudinal sides and each of said sides includes at least one rail extension connected thereto to form a partial extension.  
   
   
       28 . A telescopic extension for the horizontal or vertical extension of an element such as a cupboard element, a baking shelf or an oven door of a cooking appliance or similar device, the telescopic extension comprising: 
 a pair of interconnected rail extensions;    each of said rail extensions including; 
 at least one outer rail of bent sheet metal;  
 a sliding rail of bent sheet metal that partially surrounds said outer rail;  
 an anti-friction bearing by which said sliding rail can be displace along said outer rail;  
 an outer attachment rail connected to and reinforcing at least one of said outer rail or an attachment rail connected to said sliding rail;  
 each said attachment rail having a flat base section; and  
 said flat base sections of said pair of attachment rails joined together to form said interconnection of said rail extensions.  
   
   
   
       29 . The telescopic extension according to  claim 28 , including each of said attachment rails are formed with a U-shaped profile.  
   
   
       30 . The telescopic extension according to  claim 28 , including said attachment rails are joined together by at least one of welding, riveting, screwing or gluing.  
   
   
       31 . The telescopic extension according to  claim 28 , including the horizontal or vertical extension element has a pair of longitudinal sides and each of said sides includes at least one telescopic extension connected thereto.  
   
   
       32 . The telescopic extension according to  claim 31 , including forming a full extension of said extension element.
