Covering assembly

Abstract

A covering assembly includes a plurality of upright legs, and upper and lower canopy units. The lower canopy unit is mounted on top of the legs, and is formed with a ventilation opening. The upper canopy unit is mounted on top of the lower canopy unit, and is disposed above the ventilation opening. The upper canopy unit has a size sufficient to shield the ventilation opening while allowing air to be vented through the ventilation opening.

         7 . The covering assembly as claimed in  claim 1 , wherein said covering frame further includes a pair of reinforcing units, each of which extends transversely between an adjacent pair of said lateral rod sections of said lower canopy support rods of said upright frame units, each of said reinforcing units including: 
 a regulating seat having two opposite ends, each of which is formed with a threaded hole, said threaded holes in said opposite ends being coaxial with each other;    a pair of connecting members, each of which has a threaded shank portion extending threadedly into said threaded hole in a respective one of said opposite ends of said regulating seat, and a ring portion connected to said threaded shank portion; and    a pair of wires, each of which has an inner end hooked at said ring portion of a respective one of said connecting members, and an outer end mounted on a respective one of said lateral rod sections of said lower canopy support rods;    said regulating seat being operable to rotate relative to said connecting members about an axis of said threaded holes to cause said threaded shank portions of said connecting members to thread in and out of said threaded holes so as to adjust tension of said wires.    
     
     
         8 . A covering frame comprising: 
 at least two upright frame units, each of which includes a pair of upright legs with upper ends, and a lower canopy support rod interconnecting said upper ends of said legs, said lower canopy support rod having a pair of lateral rod sections connected respectively to said upper ends of said legs, and an intermediate rod section interconnecting said lateral rod sections, each of said lateral rod sections inclining downwardly from said intermediate rod section toward the corresponding one of said legs, each of said upright frame units further including an upper canopy support rod which is mounted on top of said intermediate rod section of said lower canopy support rod and which is spaced-apart from said intermediate rod section of said lower canopy support rod; and    a plurality of horizontal bars extending transversely between said lower canopy support rods of said upright frame units.    
     
     
         9 . The covering frame as claimed in  claim 8 , wherein said lower canopy support rod of each of said upright frame units is formed with a pair of mounting tubes which extend upwardly from said intermediate rod section, said upper canopy support rod of each of said upright frame units further having a pair of downwardly extending mounting posts which are inserted into said mounting tubes, respectively, for mounting said upper canopy support rod on said lower canopy support rod.  
     
     
         10 . The covering frame as claimed in  claim 8 , wherein said upper canopy support rod has downwardly inclining lateral portions which are disposed respectively above said lateral rod sections of said lower canopy support rod.

         12 . The covering frame as claimed in  claim 8 , further comprising a pair of reinforcing units, each of which extends transversely between an adjacent pair of said lateral rod sections of said lower canopy support rods of said upright frame units, each of said reinforcing units including: 
 a regulating seat having two opposite ends, each of which is formed with a threaded hole, said threaded holes in said opposite ends being coaxial with each other;    a pair of connecting members, each of which has a threaded shank portion extending threadedly into said threaded hole in a respective one of said opposite ends of said regulating seat, and a ring portion connected to said threaded shank portion; and    a pair of wires, each of which has an inner end hooked at said ring portion of a respective one of said connecting members, and an outer end mounted on a respective one of said lateral rod sections of said lower canopy support rods;    said regulating seat being operable to rotate relative to said connecting members about an axis of said threaded holes to cause said threaded shank portions of said connecting members to thread in and out of said threaded holes so as to adjust tension of said wires.    
     
     
         13 . A covering assembly comprising:
