Carrier rack on air-vent

Abstract

A carrier rack on air-vent comprising a clasping bracket on one side and horizontal sliding groove on the rear side; sliding groove comprises two sliding blocks that can move right and left; sliding block has a round through hole at its end; round through hole has gullets at proper position around its edge; in round through hole, arm lever is pivotally connected by bolt support along with spring; arm lever is located relative to gullets and cooperates with gullets to form a sprocket; arm lever further comprises a resilient lockout that can move back and forth under the pressure of compression spring; lockout cooperates with hook to form a clasping channel; arm lever extends into air-vent blades through the sliding channel formed by hook and lockout to clasp air-vent blades. This makes it possible to attach to air-vent quickly and via sprocket, arm lever and sliding block can rotate and engage with each other to adjust the angle of carrier and make it easier to firmly clasp heavy objects and provide easy access.

1 . A carrier rack on air-vent comprising: 
 a carrier, a pair of sliding blocks and a pair of arm levers, said carrier comprises a clasping bracket on one side and a sliding groove on the rear side, said sliding groove can engage said sliding blocks that slide left and right, each of said sliding block has a round through hole on the end, each of said round through hole has a gullets at the proper position around the edge, said arm lever connects to said round through hole with a bolt support and a spring, a sprocket locates on said arm lever corresponding to and passing through said gullet, said arm lever further comprises a resilient lockout that moves back and forth under the pressure of a compression spring, said lockout cooperates with a hook to form a clasping channel to clamp on the blade of the air-vent.    
   
   
       2 . The carrier rack on air-vent recited in  claim 1 , wherein said arm lever can be adjusted the right/left engaging position with different length.  
   
   
       3 . The carrier rack on air-vent recited in  claim 1 , wherein said lockout cooperates with a hook to form a clasping channel with offset angle that makes said carrier form an offset angle with the air-vent.  
   
   
       4 . The carrier rack on air-vent recited in  claim 1 , wherein the axis of said round through hole is unparallel to said carrier such that said carrier forms an offset angle with the air-vent.
