Cargo bracing device

Abstract

A cargo bracing device includes a base having two side plates for rotatably attaching a reel drum, one or more toothed discs attached to the reel drum and controlled to rotate relative to the base with a stop, an operating arm having two legs rotatably attached to the reel drum, a catch device attached to the operating arm and engaged with the toothed disc, and an anchoring device may detachably anchor the catch device to the operating arm for limiting the catch device to slide relative to the legs of the operating arm and for preventing the operating arm from being disengaged from the reel drum. The operating arm includes an opening formed in each leg for detachably engaging with the reel drum and for preventing the cargo from being stolen by the unauthorized persons.

1 . A cargo bracing device comprising:
 a base including two side plates, said side plates each including an orifice formed therein,   a reel drum rotatably engaged in said orifices of said side plates of said base for rotatably attaching said reel drum to said base,   at least one toothed disc attached to said reel drum and rotated in concert with said reel drum, and including a plurality of disc teeth provided thereon,   a spring-biased stop slidably attached to said base and engaged with said disc teeth of said at least one toothed disc, for limiting said at least one toothed disc and said reel drum to rotate relative to said base in an active direction and for preventing said reel drum from being rotated in a reverse direction relative to said base,   an operating arm including two legs rotatably attached to said reel drum,   a spring-biased catch device slidably attached to said operating arm and engaged with said disc teeth of said at least one toothed disc, for allowing said at least one toothed disc and said reel drum to be rotated relative to said base by said operating arm in the active direction and for preventing said reel drum from being rotated in the reverse direction relative to said base by said operating arm, and   means for anchoring said catch device to said operating arm and for limiting said catch device to slide relative to said legs of said operating arm and for preventing said operating arm from being disengaged from said reel drum.   
   
   
       2 . The cargo bracing device as claimed in  claim 1 , wherein said operating arm includes an opening formed in each of said legs for receiving said reel drum and for attaching said legs of said operating arm to said reel drum, and said opening of at least one of said legs includes an open portion for detachably engaging with said reel drum. 
   
   
       3 . The cargo bracing device as claimed in  claim 2 , wherein said catch device includes two pawls for selectively engaging into said open portion of said opening of said legs and for selectively closing said opened opening of said legs. 
   
   
       4 . The cargo bracing device as claimed in  claim 1 , wherein said anchoring means includes a latch slidably engaged through said catch device for selectively engaging with said operating arm and for anchoring said catch device to said operating arm. 
   
   
       5 . The cargo bracing device as claimed in  claim 4 , wherein a spring member is engaged between said latch and said catch device for biasing and moving said latch from said operating arm. 
   
   
       6 . The cargo bracing device as claimed in  claim 4 , wherein an actuating member is attached the catch device and engaged with said latch for actuating said latch to selectively engage with said operating arm. 
   
   
       7 . The cargo bracing device as claimed in  claim 6 , wherein said actuating member is rotatably attached the catch device with an axle and includes an actuating surface for engaging with said latch. 
   
   
       8 . The cargo bracing device as claimed in  claim 7 , wherein said actuating surface is a helical actuating surface having a deeper portion and a shallower portion. 
   
   
       9 . The cargo bracing device as claimed in  claim 8 , wherein said actuating member includes a partition provided between said deeper portion and said shallower portion of said actuating surface. 
   
   
       10 . The cargo bracing device as claimed in  claim 1 , wherein said reel drum includes two drum halves spaced away from each other for forming a strap receiving slot between said drum halves. 
   
   
       11 . The cargo bracing device as claimed in  claim 10 , wherein said at least one toothed disc include two apertures formed therein for receiving said drum halves of said reel drum respectively and for allowing said at least one toothed disc to be rotated in concert with said reel drum.
