Supporting arm for wall-mount metal rack

Abstract

A supporting arm for stably supporting a wall-mount metal rack includes a main body, and a hook section and a fixing plate integrally formed at an upper and a lower end, respectively, of the main body. Ribs are longitudinally provided at joints of the main body and the hook section and the fixing plate to enhance a structural strength thereat. The hook section provides a relatively large bearing surface to cover and support an outer transverse metal wire of the metal rack, so that the metal rack is stably mounted on the wall surface to provide a largely increased bearing capacity.

1 . A supporting arm for wall-mount metal rack, comprising a main body, a hook section integrally provided at an upper end of said main body, and a fixing plate integrally provided at a lower end of said main body; said supporting arm being made of a sheet metal material, and said fixing plate being properly bent into a predetermined configuration having a flat inner surface; 
 said supporting arm being characterized in that said hook section is a forward opened horizontal channel, and that at least one first rib is longitudinally provided at a joint of said hook section and the upper end of said main body to prevent deformation or breaking at said joint.    
   
   
       2 . The supporting arm for wall-mount metal rack as claimed in  claim 1 , wherein said main body has at least one second rib longitudinally provided at an upper part thereof.  
   
   
       3 . The supporting arm for wall-mount metal rack as claimed in  claim 2 , wherein said first rib provided at said joint of said hook section and the upper end of said main body and said second rib provided at the upper part of said main body are staggered without locating on the same one straight line.  
   
   
       4 . The supporting arm for wall-mount metal rack as claimed in  claim 1 , wherein said hook section and said main body contain between them an angle of 45 to 90 degrees, so that said hook section provides a relatively large bearing surface to cover and support a transverse metal wire located at an outer edge of a metal rack.  
   
   
       5 . The supporting arm for wall-mount metal rack as claimed in  claim 1 , wherein said hook section is provided with a slit extended in a direction normal to said horizontal channel and communicating with an inner space of said horizontal channel.  
   
   
       6 . The supporting arm for wall-mount metal rack as claimed in  claim 1 , further comprising a third rib longitudinally provided at a joint of said main body and said fixing plate to enhance a structural strength at said joint.  
   
   
       7 . The supporting arm for wall-mount metal rack as claimed in  claim 6 , wherein said fixing plate has a sidewall extended along two lateral edges and a lower edge of said fixing plate to increase an overall strength of said fixing plate.
