Structure of hook for a truck

Abstract

A structure of hook for a truck includes a plurality of hooks spacedly secured on the top of two side walls of the cargo body of the truck for binding the ropes each having a hollow post embedded into the wall, a hook member engageable into the hollow post, a positioning plate, a cushion and a top plate each having an central opening for permitting the hook member passing through and superimposed with each other for securing to the top of the lateral walls of the cargo body of the truck. The present invention is characterized in that a partition formed between a pair of extensions of the hook member to define a spring compartment and a sliding compartment in which is a V-shaped groove communicating to a Y-shaped groove to allow a U-shaped bar sliding about. So that the hook member may be hid in or jumped out of the hollow post.

I claim:  
     
         1 . A structure of hook for a truck comprising: 
 a hollow post embedded into a top of lateral walls of a cargo body of the truck and having rectangular plate perpendicularly and partially integrated with top of the hollow post, a rectangular opening in center of the plate, a pair of circular thru holes respectively formed on lateral sides of the opening, a reduced bottom including a projection projected upward from a top abutting a first side an indentation in a second side thereof and a recess in an upper wall of the indentation;    a hook member engageable into the hollow post having a hook, a pair of rectangular extension extended downward from the hook, a partition positioned at a center of the extensions therebetween to define a spring compartment and a sliding compartment in two side and a V-shaped groove communicating to a Y-shaped groove inside the sliding compartment and in a surface of the portion;    a spring mean having an upper portion received in the spring compartment of the hook member and a lower end engaged with the projection of the reduced bottom of the hollow post;    a U-shaped bar having a lower transverse portion movably inserted into the recess of the reduced bottom of the hollow post and secured by a band and an upper transverse portion slidably engaged in the Y-shaped groove and the V-shaped groove;    a positioning plate wrapped on the hollow post having a pair of side walls engaged with an underside of the rectangular plate of the hollow post abutting two lateral sides thereof a first narrow rectangular opening in a center engaged with the hollow post and a pair of first screw holes respectively formed on lateral side of the opening engageable with the circular thru holes of the rectangular plate of the hollow post;    a cushion deposed on top of the hollow post having a large rectangular opening in a center engaged with rectangular plat of the hollow post;    a top plate deposed on top of the cushion having a size equal to the cushion, a second narrow opening in a center engageable with the hook member and a pair of second screw holes respectively formed on lateral sides of the opening;    a pair of bolts secured the top plate, the cushion, the hollow post and the positioning plate to a top of cargo body of the truck through the second screw holes, the circular thru holes and the first screw holes;    whereby, a first press makes the hook member hid in the hollow post and a second press make the hook member jumped up to outside of the top plate.    
     
     
         2 . The structure as recited in  claim 1  wherein said V-shaped groove has a right portion having the depth deeper than the Y-shaped groove and a left portion having a sloped connected to the left portion of the Y-shaped groove and the deeper right portion thereof.
