Toolbox module

Abstract

A toolbox module comprises a housing and a box received in the housing. The housing includes a number of holes in an upper side thereof and a corresponding number of protrusions on an underside thereof for engaging with the holes of another toolbox module. The housing includes at least one hanging hole in a rear side thereof. The housing may further include a vertical dovetail groove and a vertical dovetail column on the rear side thereof. The housing includes two opposite lateral outer surfaces. A vertical dovetail groove is defined in one of the lateral outer surfaces of the housing and a dovetail column is formed on another lateral outer surface of the housing.

         7 . The toolbox module as claimed in  claim 6 , wherein the rear side of the housing of the toolbox module includes at least one hanging hole.  
     
     
         8 . The toolbox module as claimed in  claim 1 , wherein the housing of the toolbox module includes two opposite lateral outer surfaces, a vertical dovetail groove being defined in one of the lateral outer surfaces of the housing, a dovetail column being formed on another lateral outer surface of the housing.  
     
     
         9 . The toolbox module as claimed in  claim 8 , wherein the housing of the toolbox module includes at least one hanging hole in a rear side thereof.  
     
     
         10 . The toolbox module as claimed in  claim 8 , wherein the housing of the toolbox module includes a plurality of holes in an upper side thereof and a corresponding number of protrusions on an underside thereof for engaging with the holes of another said toolbox module.  
     
     
         11 . The toolbox module as claimed in  claim 10 , wherein the housing of the toolbox module includes at least one hanging hole in a rear side thereof.  
     
     
         12 . The toolbox module as claimed in  claim 8 , wherein the housing of the toolbox module includes a further vertical dovetail groove and a further vertical dovetail column on a rear side thereof.  
     
     
         13 . The toolbox module as claimed in  claim 12 , wherein the rear side of the housing of the toolbox module includes at least one hanging hole.  
     
     
         14 . The toolbox module as claimed in  claim 1 , wherein the housing of the toolbox module includes two lateral inner surfaces, each said lateral inner surface including a positioning groove and a track formed thereon, the box of the toolbox module including two opposite lateral outer surfaces each having a first peg and a second peg located above the first peg, each said first peg being pivotally received in an associated said positioning groove, each said second peg being slidably guided in an associated said track.  
     
     
         15 . The toolbox module as claimed in  claim 14 , wherein the track is in the form of an arcuate guide rib.  
     
     
         16 . The toolbox module as claimed in  claim 15 , further comprising a second guide rib on each said lateral inner surface for guiding an associated said first peg into the associated positioning groove.  
     
     
         17 . The toolbox module as claimed in  claim 2 , wherein the housing of the toolbox module includes two lateral inner surfaces, each said lateral inner surface including a positioning groove and a track formed thereon, the box of the toolbox module including two opposite lateral outer surfaces each having a first peg and a second peg located above the first peg, each said first peg being pivotally received in an associated said positioning groove, each said second peg being slidably guided in an associated said track.  
     
     
         18 . The toolbox module as claimed in  claim 17 , wherein the track is in the form of an arcuate guide rib.  
     
     
         19  The toolbox module as claimed in  claim 18  further comprising a second guide rib formed on each said lateral inner surface for guiding an associated said first peg into the associated positioning groove.  
     
     
         20 . The toolbox module as claimed in  claim 4  wherein the housing of the toolbox module includes two lateral inner surfaces, each said lateral inner surface including a positioning groove and a track formed thereon, the box of the toolbox module including two opposite lateral outer surfaces each having a first peg and a second peg located above the first peg, each said first peg being pivotally received in an associated said positioning groove, each said second peg being slidably guided in an associated said track.
