Structure assembly assembled without tools

Abstract

A structure device includes a number of couplers each having a vertical barrel to receive ends of vertical ducts, and one or more arms extended from the vertical barrel to engage into horizontal conduits. Each of the horizontal conduits includes one or more ears engaged into lock notches via channels of the arms, when the horizontal conduits are rotated relative to the arms, so as to couple the horizontal conduits and the vertical ducts without additional fasteners or tools. One or more covers may have two angle members attached to two corner portions and rotatably engaged into the arms with axles, to rotatably secure the cover to the couplers.

I claim:  
     
         1 . A structure assembly comprising: 
 a plurality of couplers each including a vertical barrel having a bore formed therein, and a peripheral flange extended into said bore of said vertical barrel to form an aperture in said peripheral flange,    said couplers each including a first arm and at least one second arm extended from said vertical barrel respectively,    a plurality of vertical ducts each including an end portion engaged into said bores of said vertical barrels of said couplers respectively, and engaged with said peripheral flange of said vertical barrel respectively,    a first vertical duct of said vertical ducts including a lock nut disposed in said end portion thereof, and a second vertical duct of said vertical ducts including a fastener disposed therein and extended therefrom and engaged through said aperture of said vertical barrel, to thread with said lock nut of said first vertical duct, and to secure said first vertical duct and said second vertical duct to said vertical barrel respectively,    a plurality of horizontal conduits each including a bore formed therein, and an ear extended into said bore of each of said horizontal conduits, and    said first arms and said at least one second arms of said couplers each including a shank extended therefrom and engaged into said bore of said horizontal conduits respectively, said shanks each including a channel formed therein, to receive said ear of said horizontal conduits respectively, and said first arms and said at least one second arms each including a lock notch formed therein and communicating with said channel of said shanks, to receive said ear of said horizontal conduits respectively, when said horizontal conduits are rotated relative to said first arms and said at least one second arms respectively,    said horizontal conduits and said vertical ducts being secured and coupled together with said couplers without additional fasteners or tools.    
     
     
         2 . The structure assembly as claimed in  claim 1 , wherein each of said shanks includes a second channel formed therein and opposite to said channel thereof, each of said horizontal conduits includes a second ear extended into said bore thereof and engaged into said second channels of said shanks respectively, to further secure said horizontal conduits to said shanks.  
     
     
         3 . The structure assembly as claimed in  claim 2 , wherein each of said first arms and said at least one second arms of said couplers further includes a second lock notch formed therein and communicating with said second channel of said shanks, to receive said second ear of said horizontal conduits respectively, when said horizontal conduits are rotated relative to said first arms and said at least one second arms respectively.  
     
     
         4 . The structure assembly as claimed in  claim 1 , wherein said fastener includes a head secured in said second vertical duct, and said fastener is partially extended out of said second vertical duct to extend through said aperture of said vertical ducts, and to thread with said lock nut of said first vertical duct, and to secure said first vertical duct and said second vertical duct to said vertical barrel respectively.  
     
     
         5 . The structure assembly as claimed in  claim 1  further comprising at least one board including four corner portions, and four angle members each including a slot formed therein to receive said corner portions of said boards respectively, and said angle members each including two curved depressions formed in an outer peripheral portion thereof to engage with said vertical ducts and said horizontal conduits respectively, and to retain said at least one board between said vertical ducts and said horizontal conduits.  
     
     
         6 . The structure assembly as claimed in  claim 1  further comprising a cover including two corner portions, and two angle members each including a space formed therein to receive said corner portions of said cover respectively, each of said first arms and said at least one second arms of said couplers including a cavity formed therein, and said angle members each including an axle extended therefrom and rotatably engaged into said cavities of said first arms and said at least one second arms respectively, to rotatably secure said cover to said couplers with said angle members.  
     
     
         7 . The structure assembly as claimed in  claim 1 , wherein each of said couplers includes a lever laterally extended therefrom, and said structure assembly further includes a plate disposed and supported on said levers of said couplers.  
     
     
         8 . The structure assembly as claimed in  claim 7 , wherein each of said couplers includes a sucker member disposed on said lever to engage with said plate and to retain said plate on said levers.  
     
     
         9 . The structure assembly as claimed in  claim 8 , wherein each of said levers includes an orifice formed therein, said each of said sucker members includes a stud extended therefrom and engaged into said orifices of said levers respectively, to secure said sucker members on said levers respectively.  
     
     
         10 . The structure assembly as claimed in  claim 7 , wherein said plate includes a peripheral skirt extended from an outer peripheral portion thereof, to engage with said horizontal conduits, and to secure and retain said plate between said horizontal conduits.
