Abstract
A storage container for a trailer king pin lock having a sleeve dimensioned to be coaxially received over a trailer king pin and a lock mechanism protruding from an exterior surface of the sleeve. The container includes a base dimensioned for seating a bottom end of the lock sleeve when not in use and a mount is provided for securing the base of the container alternatively to a tractor or a trailer adjacent the trailer king pin for convenient access. When the king pin lock is not in use it is secured to the base and a cover is secured over the lock and base to prevent exposure of the greasy dirty surfaces of the lock from engaging other objects and for convenient storage for later use.
Description
- The present invention relates to anti-theft locking arrangements for prevention of the unauthorized coupling of truck tractors and truck trailers, and more particularly to a storage container for the lock when not in use.
- The standard mechanism used to couple truck tractors and trailers includes a fifth wheel mounted on the truck tractor and a king pin mounted on the trailer. Typically, the king pin extends downwardly from the trailer and has an annular groove located around the outer surface of the king pin. The fifth wheel has a slot or a set of jaws which are adapted to engage the grooved king pin.
- Various locking arrangements for the prevention of unauthorized coupling of a fifth wheel of a tractor to the king pin of a trailer have been developed. For example, see U.S. Pat. Nos. 3,798,938; 4,697,444; 4,704,883 and 5,052,203. Basically all of these locking arrangements are essentially comprised of a sleeve dimensioned to be coaxially received over a trailer king pin and a lock mechanism protruding from an exterior surface of the sleeve, which lock mechanism may be activated with a key which extends and engages a lock bolt into the groove of the king pin.
- A common problem incurred with all of these locking mechanisms is that by necessity they are covered with grease, as an extensive amount of grease is used on the fifth wheel and the king pin. This grease together with dirt is transferred to the locking mechanism which creates the common problem as to what the trucker should do with the locking mechanism when not in use. It is extremely dirty to handle and it will apply greasy dirt to any object that it comes in contact with. Accordingly, it is a principal object of the present invention to provide a convenient means for storing the lock when not in use.
- The present invention provides a storage container for a trailer king pin lock, which lock conventionally has a sleeve dimensioned to be coaxially received over a trailer king pin and a lock mechanism protruding from an exterior surface of the sleeve. The storage container of the present invention is comprised of a base dimensioned for seating a bottom end of the lock sleeve and the base is further provided with means for securing it to a truck tractor or a truck trailer adjacent to the king pin where access is convenient. A means is also provided for securing the lock to this base.
- This securing means may include a sleeve extending upwardly from the base and dimensioned for coaxially receiving the lock sleeve thereover and have a lock bolt aperture therethrough to receive a lock bolt from the king pin lock.
- A cover is provided and dimensioned to cover the lock to thereby prevent exposure of the dirty grease deposited on the king pin lock. A cover lock is provided to secure this cover to the base. This cover lock may include a spring loaded bayonet lock mechanism on the cover which penetrates into the sleeve for locking engagement with the base.
- Other objects and advantages appear hereinafter in the following description and claims. The accompanying drawings show, for the purpose of exemplification, without limiting the invention or the appended claims, certain features of the present invention wherein:
-
FIG. 1 is a schematic view in side elevation of a truck tractor and an unattached truck trailer with a king pin locking mechanism applied thereto and further illustrating the storage container of the present invention shown alternatively secured to the tractor or the trailer; -
FIG. 2 is a perspective view of a trailer king pin lock of the prior art representing one of a number of such locks which may be utilized with the storage container of the present invention; -
FIG. 3 is a plan view of the lock shown inFIG. 2 ; -
FIG. 4 is a perspective view of the storage container of the present invention for a trailer king pin lock of the type shown inFIGS. 2 and 3 ; -
FIG. 5 is a top or plan view of the storage container shown inFIG. 4 ; -
FIG. 6 is a bottom view of the cover, exposing the interior thereof, for the storage container shown inFIGS. 4 and 5 ; -
FIG. 7 is a top or plan view of the storage container shown inFIGS. 4 and 5 with the cover removed to thereby expose the interior of the container base with the king pin lock mounted thereon; -
FIG. 8 is a perspective view of the base portion of the storage container illustrated inFIG. 7 with the king pin lock removed; and -
FIG. 9 is a plan or top view of the base portion of the container shown inFIG. 8 . - Referring to
FIG. 1 , atruck tractor 10 is schematically illustrated along with, but not attached to, thetruck trailer 11. As may be best noted from the exploded portion of the drawing, theking pin 12 depends downwardly fromtrailer tongue 13 for ultimate engagement with thefifth wheel 14 on thetractor 10 for towing thetrailer 11. Theking pin 12 is provided with anannular groove 15 to receive the jaws (not shown) on thefifth wheel 14. Thetrailer 11 is shown in a parked position and theking pin lock 16 is applied to theking pin 12 to prevent theft of thetrailer 11 in a well known manner. - Once the
king pin lock 16 is removed, it is then stored in the storage container of the present invention as alternatively indicated at 17 on the truck tractor or the tongue oftrailer 11, as will be explained in more detail hereinafter. - Referring next to
FIGS. 2 and 3 , the details of the conventionalking pin lock 16 are illustrated. Thelock 16 is comprised of asleeve 18 dimensioned to be coaxially received over thetrailer king pin 12 and alock mechanism 19 protrudes from the exterior surface ofsleeve 18. Thelock mechanism 19 is actuated with a key in conventional fashion to extend and retractlock bolt 20 into theannular groove 15 ofking pin 12. - The
storage container 17 of the present invention for the kingpin lock mechanism 16 is shown and described in detail inFIGS. 4 through 9 . Thestorage container 17 includes abase 21 dimensioned for seating a bottom end oflock sleeve 18. Thebase 21 is provided withbolt passages 22 in order to provide a mounting means for securing thebase 21 to atractor 10 or atrailer 11 with bolts or other fasteners as alternately illustrated inFIG. 1 adjacent to thetrailer king pin 12 for convenient storage. Then a securing means is provided for securing thelock 16 to thebase 21. This is accomplished in the embodiment illustrated by providing aninner sleeve 24 that is secured to and extends upwardly frombase 21 and is further dimensioned to coaxially receivesleeve 18 oflock 16 thereabout. Thisinner sleeve 24 is further provided with alock bolt aperture 25 in the side thereof to receivelock bolt 20 therethrough to thereby secure thelock 16 tobase 21. -
Cover 23 is also provided to cover the securedlock 16 as it rests onbase 21 in order to prevent exposure thereof and its greasy d0irty surfaces to possible contact with other objects. Thiscover 23 is suitably constructed of lightweight aluminum or plastic. Thelock 16 and thebase 21 are generally constructed of steel. - The
cover 23 is dimensioned to cover thelock 16 and engage the bottom ofbase 21 in order to fully cover thelock 16. Thecover 23 is secured tobase 21 by means of a spring loadedbayonet lock mechanism 26 which penetrates into theinner sleeve 24 for locking engagement withbase 21. Thisbayonet lock mechanism 26 includes a vertical pin orshaft 27 which in turn has secured to its upper end aknob 28 for manipulating theshaft 27. The bottom end ofshaft 27 is provided with abayonet locking pin 29 which extends transversely throughshaft 27 for bayonet locking engagement with the femalebayonet locking mechanism 30 provided on the upper end ofextension lock tube 31, which is centrally secured to the bottom ofbase 21. - The
mechanism 26 is further spring loaded by means ofcompression spring 32 which is disposed betweenknob 28 and the upper exterior surface ofcover 23. This permitsknob 28 to be depressed downwardly against compression ofspring 32 to thereby protrudeshaft 27 downwardly to engagebayonet pins 29 into thefemale bayonet slots 30 oftube 31 to thereby securely lock the cover over thebase 21 and thelock 16 secured therein.
