Collapsible utility trailer

Abstract

A collapsible utility trailer having a trailer bed, a trailer frame, a front pair of wheels and a rear pair of wheels. The trailer bed has at least two bed sections and each of the bed sections has a length and a width. The trailer frame has a plurality of frame sections and each of the trailer frame sections have a length and a width that are less than the length and the width of the bed sections, respectively. The trailer bed sections are attached to the trailer frame. The front and rear pairs of wheels rotatably attached to the trailer frame so that the front and rear wheels are oriented substantially below the trailer bed.

1 . A trailer of modular construction, comprising: 
 a selectively extendable modular frame having a plurality of frame modules, the frame being extendable by means of additional frame modules; and    a selectively extendable modular bed supportable on the frame and having a plurality of bed modules, the bed being extendable by means of additional bed modules.    
   
   
       2 . The trailer of  claim 1 , the bed modules being of substantially the same size.  
   
   
       3 . The trailer of  claim 1 , the bed modules being of substantially the same construction.  
   
   
       4 . The trailer of  claim 3 , the bed modules being of frame and mesh construction.  
   
   
       5 . The trailer of  claim 1  having at least three bed modules.  
   
   
       6 . The trailer of  claim 1  including a plurality of shiftable, mutually supportable side wall panels couplable to the modular bed.  
   
   
       7 . The trailer of  claim 6 , the side wall panels being couplable to the modular bed by means of readily removable pins.  
   
   
       8 . The trailer of  claim 6 , the plurality of side wall panels being selectively shiftable from an upright disposition to a depending disposition.  
   
   
       9 . A method of forming a trailer of modular construction, comprising: 
 forming a modular frame of a plurality of frame modules and selectively extending the frame by means of additional frame modules; and    supporting a modular bed on the frame, forming the modular frame of a plurality of bed modules, and extending the bed by means of additional bed modules.    
   
   
       10 . The method of  claim 9  including forming the bed modules of substantially the same size.  
   
   
       11 . The method of  claim 9  including providing at least three bed modules.  
   
   
       12 . A trailer of modular construction, comprising: 
 a selectively extendable modular frame having a plurality of frame modules; and    a selectively extendable modular bed supportable on the frame and having a plurality of bed modules, each of the plurality of bed modules being supportable at least in part by a respective frame module.    
   
   
       13 . The trailer of  claim 12 , the bed modules being of substantially the same size.  
   
   
       14 . The trailer of  claim 12 , the bed modules being of substantially the same construction.  
   
   
       15 . The trailer of  claim 14 , the bed modules being of frame and mesh construction.  
   
   
       16 . The trailer of  claim 12  having at least three bed modules.  
   
   
       17 . The trailer of  claim 12  including a plurality of shiftable, mutually supportable side wall panels couplable to the modular bed.  
   
   
       18 . The trailer of  claim 17 , the side wall panels being couplable to the modular bed by means of readily removable pins.  
   
   
       19 . The trailer of  claim 17 , the plurality of side wall panels being selectively shiftable from an upright disposition to a depending disposition.  
   
   
       20 . The trailer of  claim 14 , the side wall panels being of frame and mesh construction.
