Patent ID: 8721240

Claim:
A cargo bracing device comprising: a fixing member provided with two side plates integrally made with a connecting plate provided with an elastic device base for being fitted with one end of an elastic device, said side plates respectively provided with a hole bored in one end for being inserted by a bolt to connect with each other, a winding shaft hole bored in another end of said side plates respectively for a winding shaft made of two semi-annular steels to pass through, two ratchets respectively fitted on two ends of said winding shaft outside said side plates and provided with two semi-annular holes for being correspondingly inserted by said semi-annular steels of said winding shaft, a C-shaped fixer locked around two ends of said winding shaft outside said ratchets respectively to make said ratchets position said side plates respectively bored with a lengthy hole for two ends of a locking plate to pass through, said winding shaft able to rotate under operating said locking plate in association with said ratchets, said locking plate further provided with an elastic device base to engage with another end of said elastic device so as to provide dynamic force for restoring said locking plate; and a driving member provided with two wings having one end riveted with a grip bar, a first connecting bar and a second connecting bar further riveted with said wings to strengthen them, said wings respectively provided with a sloped lengthy hole for fitting two guiding portions of an actuating plate respectively, an extension extended outward of each said guiding portion to pass through a curved lengthy hole bored in two driven plates respectively, said driven plates respectively provided with a connecting bar hole for said second connecting bar to pass through, said second connecting bar employed as a fulcrum for deflection of said driven plates, said wings respectively having another end formed as a hook collaborating with a latch of said driven plates respectively to lock on two ends of said winding shaft, said guiding portions of said actuating plate able to move in said lengthy holes of said wings and said extensions of said actuating plate able to move in said curved lengthy holes of said driven plates while operating said actuating plate so that said actuating plate is to deflect with a certain track with said second connecting bar as a fulcrum and said hooks of said wings and said latches of said driven plates are to open wide to make said driving member separable from said fixing member.
