Kingpin lock holder

Abstract

The present invention is a one piece, durable, cylinder-like device that is inserted within the main cylinder part of a kingpin lock. One preferred embodiment, of several, has an outside diameter in close tolerance to the inside diameter of a kingpin lock device. In addition, the holder is easily insertable into the kingpin lock device. A round hole is located within the wall of the holder such that the hole in a cylinder wall of each kingpin lock device aligns with the hole in the holder. The diameter of the hole in the holder is sufficient to allow a metal tongue to be inserted from the kingpin lock device through the hole in the holder. Then a key in the lockpin device is removed leaving the lock device secured to the holder. In addition, the holder has a metal plate perpendicularly welded to the cylinder part. Then bolts are used to secure the holder to another metal surface. The surface could be the underside of a trailer or box or in a storage compartment behind the cab of a tractor.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates generally to holding devices, and, more specifically, to a holder for a kingpin lock device. A kingpin is used in the trucking industry to join a tractor to a flatbed trailer or a box. [0003] 2. Description of the Related Art [0004] The trucking industry moves the vast majority of all goods within the United States. The volume is staggering. More importantly, the value of these goods is billions of dollars every day. Therefore, some means of protection and security is needed to minimize losses due to theft of the trailers or boxes that are hauled using tractors. For example, one method of security used in hauling tobacco products by truck is heavily armed guards and deception. The primary and loaded tractor trailer rig is sent in one direction, while a second tractor trailer rig is used as a decoy. However, the dominant method used for security is the kingpin lock. First, a kingpin is d...

Benefits of technology

[0009] The above-mentioned difficulties and problems are overcome by the present invention. The present invention is an elegantly simple device. Applicant's Kingpin Lock Holder is a one piece, durable, cylinder-like device that is inserted within the main cylinder part of a kingpin lock. One preferred embodiment is used with the two primary kingpin lock devices previously described. The holder has an outside diameter in close tolerance to the inside diameter of either lock device. In addition, the holder is easily insertable into either lock device. A round hole is located within the wall of the holder such that a recess in the cylinder wall of each lock device aligns with the the round hole in the holder. The diameter of the hole in the holder is sufficient to allow the metal tongue to be inserted from the lock device through the hole in the holder. Then the key in the kingpin lock device is removed leaving the kingpin lock secured to the holder. In addition, the kingpin lock holder has a metal plate perpendicularly welded ...

Problems solved by technology

The reason the kingpin lock cannot be removed from the kingpin is 1) because the key is necessary for locking and unlocking the lock, 2) the metal tongue cannot be slipped off the kingpin since the kingpin upper and lower diameters are greater than the center diameter where the metal tongue is in contact, and 3) because the metal cylindrical walls of the kingpin locks are thick enough to make removable by a cutting torch highly impractical and time consuming.

Unfortunately, the kingpin locks have some major disadvantages.

Because the slot on the tractor is heavily greased, the ki...
