Automated awning

Abstract

An automated awning comprises a main shaft connected to a screw rod through a sleeve by a screw means. The screw rod is driven to activate a first support rod and a second support rod to slide forward or backward sliding motion. A main support bracket is disposed between the main shaft and a second support rod, and a spring is disposed between the main support bracket and the main shaft. There are deep and shallow grooves and a slopped surface within the second support rod; a free rotor and a fixed rotor are inserted therein. A tube body is mounted on a mount and enclosing the first support rod. The tube body is then inserted into an outer tube. As the screw rod drives the first and second support rods forward, a gear teeth strip on one side of said first link rod stretches a spring so as to open a sun roof by extending the second main support rod, the second link rod and the third main support rod; the rotors are retained on the slopped surface for fixing the main support bracket.

1 . An automated awning, comprising:
 a screw rod for urging a first support rod and a second support rod to slide along an axial direction when said screw rod is driven, also pushing a free rotor and a fixed rotor so as to drive a main support bracket and a first main support rod;   a tube body enclosing said screw rod and mounted on a mount;   said first support rod provided with a first block piece, whereby said first support rod will be stopped by a ring stop on one side of said tube body, a front end of the first support rod being further provided with a fixing first mount, whereby said first support rod and said tube body will be held together tightly by an outer ring stop of said tube body;   said second support rod with a top fixing second mount provided with inner grooves of different depth, a slopped surface and an inner screw thread, said second support rod containing said free rotor and said fixed rotor, said second support rod further including a second block piece for engaging with ring stop at one end of said first support rod;   a main shaft connected to said screw rod through a sleeve by a screw; and   said main support bracket disposed between said main shaft and said second support rod, said main support bracket further comprising a first main support rod with one end connected to said main support bracket and driven by said main support bracket to carry a main link rod and a first link rod, a main link rod with a first end connected to a fixing third mount of a second main support rod and a second end connected to a predetermined location on said first main support rod, said first link rod attached to one end of a spring with a first end provided with a teeth strip that is engaged with a gear wheel on a second main support rod and a second end connected to a predetermined location on said main link rod, a second main support rod attached to another end of said spring with a first end provided with a teeth strip that is engaged with a gear wheel on a first main support rod and a second end connected to a predetermined location on a third main support rod, a second link rod with a first end connected to said first main support rod and a second end connected to said third main support rod and said third main support rod with a free first end and a second end connected to said second main support rod and said second link rod.   
     
     
         2 . The automated awning of  claim 1  further comprising an outer tube. 
     
     
         3 . The automated awning of  claim 1  wherein said screw rod further comprises four tube parts of various diameters, achieving a contractible rod. 
     
     
         4 . The automated awning of  claim 3  wherein one of said tube parts is provided with a back-and-forth movable push head for pushing said free rotor and said fixed rotor. 
     
     
         5 . The automated awning of  claim 1  wherein said second support rod is provided with said outer ring stop for confining said first support rod with said second support rod. 
     
     
         6 . The automated awning of  claim 1  wherein a spring is disposed between said main support bracket and said main shaft. 
     
     
         7 . The automated awning of  claim 1  wherein said main support bracket is provided with a taper shank twist connector whose top end compresses said spring against a flange around said main shaft, and whose rear end is supported against said free rotor and said fixed rotor. 
     
     
         8 . The automated awning of  claim 7  wherein said taper shank twist connector further comprises a connection portion connected to said first main support rod. 
     
     
         9 . The automated awning of  claim 1  wherein said main support bracket further comprises an engagement section for connecting said main link rod. 
     
     
         10 . The automated awning of  claim 1  wherein said fixed rotor is provided with a plurality of bulged outer pieces. 
     
     
         11 . The automated awning of  claim 1  wherein said free rotor is provided with a plurality of depressed outer pieces. 
     
     
         12 . (canceled) 
     
     
         13 . The automated awning of  claim 1  wherein said first main support rod is lifted by said main support bracket, simultaneously driving said main link rod and said first link rod; a gear teeth strip on one side of said first link rod stretching a spring so as to open a sun roof by extending said second main support rod, said second link rod and said third main support rod; said rotors being retained on said slopped surface for fixing said main support bracket. 
     
     
         14 . (canceled) 
     
     
         15 . The automated awning of  claim 1  wherein said taper shank twist connector of said main support bracket is engaged with said fixed second mount of said second support rod when said automated awning is in a closed configuration; said taper shank twist connector of said main support bracket keeping a proper distance to said fixed mount of said second support rod when said automated awning is in an open configuration.
