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 by a motor 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 motor 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.

What is claimed is: 
     
         1 . An automated awning, comprising:
 a screw rod driven by a motor for urging a first support rod and a second support rod to slide along an axial direction, said also pushing a free rotor and a fixed rotor  40  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 motor mount, said a tube body further including   a first support rod is provided with a 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 mount, whereby a first support rod and a tube body will be held together tightly by an outer ring stop of said tube body;   a second support rod with a top fixing mount provided with inner grooves of different depth, a slopped surface and an inner screw thread, said second support rod containing a free rotor and a fixed rotor, said second support rod further including a 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   a 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 mount of a second main support rod and a second end connected to a predetermined location on said first main support rod, a first link rod attached with 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 with a 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 a third main support rod and a third main support rod with 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 an 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  600  is provided with a taper shank twist connector whose top end compresses said spring against a flange around said main shaft  500 , 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  610  further comprises a connection portion connected to said first main support rod. 
     
     
         9 . The automated awning of  claim 1  wherein said main support bracket  600  further comprises an engagement section for connecting said main link rod. 
     
     
         10 . The automated awning of  claim 1  wherein said fixed rotor  40  is provided with a plurality of bulged outer pieces  401 . 
     
     
         11 . The automated awning of  claim 1  wherein said free rotor is provided with a plurality of depressed outer pieces. 
     
     
         12 . The automated awning of  claim 1  wherein said slopped surface is for confining said free rotor and said fixed rotor, thereby said main support bracket being retained; said motor driving said screw rod for pushing said free rotor to engage with said fixed rotor  40  and then be guided by said slopped surface to enter said deep groove. 
     
     
         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 . The automated awning of  claim 1  wherein said first main support rod is descended by said main support bracket, said main link rod and said first link rod converging toward said second support rod simultaneously; a contractible spring pulling back said second main support rod, said second link rod and said third main support rod; said motor drawing said first support rod, said second support rod, said main link rod, said various main support rods and link rods into said outer tube, thereby achieving a closing process saving manpower and time and a closing configuration saving space. 
     
     
         15 . The automated awning of  claim 1  wherein said taper shank twist connector of said main support bracket is engaged with said fixed 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.
