Patent attributes
A device has a chain fitting which is connected to the floor of a transportation vehicle, such as a flatbed trailer. The chain fitting has a cap on one end thereof, which is installed in a mating aperture formed in the vehicle floor. The side rail has an aperture opposite the floor aperture, this aperture having a smaller diameter than the floor aperture. A side rail is installed along an edge of the floor, tis side rail having an aperture positioned opposite the aperture in the floor and having a smaller diameter than the floor aperture. The cap is installed on the top side of the floor with a short chain piece attached thereto running through the aperture with a second cap at the lower end which is secured to the lower end of the chain. A length of securing chain is attached to the chain fitting, this securing chain being attached to cargo to be restrained. The cap is partially beveled along its contact surface with the floor and engages the sides of the aperture in the floor. This beveled portion operating in conjunction with the aperture sides enables ready release of the cap with one's fingers.
