BACKGROUND OF THE INVENTION
Field of the Invention
This invention relates to cargo handling and more particularly to a cargo handling device for a vehicle.
Background of the Invention
Part and equipment storage in vans and small trucks has produced a large number and variety of vehicle mounted racks. These racks have provided a great convenience to the user by keeping parts and equipment organized and readily accessible. The necessity to repeatedly enter and exit the vehicle led to the development of racks and shelving units that were removable from within the vehicle, for use at ground level. These racks generally contained relatively small drawers or compartments to store small parts and or tools. The need for a system to store larger tools, equipment and parts and be able to be accessed external to the vehicle and at ground level has remained unanswered.
There have been many in the prior art who have attempted to solve these problems with varying degrees of success. None, however completely satisfies the requirements for a complete solution to the aforestated problem. The following U.S. patents are attempts of the prior art to solve this problem.

U.S. Pat. No. 4,479,953 to Thorley discloses a lift characterized by its ability to be simply retrofitted into a van or similar vehicle of virtually any style construction without requiring the modification of the existing structure. The unit comes in a small, neat package which is hinged on a vertical axis to a door post adjacent the hinge of one of the doors. The mounting plate of the unit which mounts the hinge also mounts a slide in its distal end which slides in a track in the door, so that as the door is opened the mounting plate is supported at one end by its hinge and at the other end in the slide. A horizontal carrier slides outwardly on tracks on the mounting plate, so that the unit clears the vehicle structure, and then a vertical carrier descends from the horizontal carrier by virtue of a hydraulic actuator. A folding platform then swings down on its horizontal hinge along the lower edge of the vertical carrier, and the various extensions and safety flaps necessary for proper operation are then deployed from within the platform structure. In its deployed mode, the platform is vertically moved on the vertical carrier, and is subsequently stowed by drawing the collateral structure into the platform, swinging the platform from its horizontal position up vertically against the horizontal and vertical carriers, with the carrier being telescoped so that all three units define a small package which can slide inwardly on the mounting plate permitting the door to close, so that the entire lift package, when not deployed, is neatly stowed in a relatively small space in the interior of the van.

The frame has at least two horizontal channels supported thereon and a sliding carriage which is slidably mounted in the channels and supported by the channels and which can be slide from a first position in the vehicle to a second position extending from the vehicle. The sliding carriage has a panel attached thereto with a plurality of storage members attachable to the panel. The panel has attaching openings therein for attaching storage bins. The locking conventional allows the sliding storage carriage to be locked in place in the vehicle and to be released from outside the vehicle for sliding the carriage to a position extending from the vehicle.
U.S. Pat. No. 5,029,935 to Dufrancatel discloses an arrangement for shifting a piece of furniture through an opening in a vertical partition, such as a wall of a vehicle. The invention includes a linkage system which maintains the orientation of the piece of furniture as it is moved between two extreme positions, wherein one of the positions is offset to be lower than the other position. When incorporated in a vehicle, the lateral offset between the two extreme positions is approximately equal to the height of the floor of the vehicle above a ground surface so that if the piece of furniture is a kitchen unit, such as a stove, its working surfaces will be at the same height for use inside the vehicle as when used in the outer position outside the vehicle.
U.S. Pat. No. 5,201,575 to Stolzel discloses a container for storing cylindrical articles in a readily accessible manner, comprising an open ended channel shaped cabinet body having a bottom and two side walls and rails upstanding from the cabinet body bottom and extending longitudinally thereof. A drawer is slidable in the cabinet body on the rails and having a front end, a back wall, a bottom, and side walls upstanding from the bottom; and cooperating pivoting structure located near the front of the cabinet body and the rear of the drawer to permit a hinging-like rotation of the drawer on the body, whereby to enable the drawer to hang downwardly from the front end of the body for article handling. The cooperating pivoting structure comprises an upstanding, inwardly directed flange member at the front edge of each cabinet body side wall, and a ledge member extending beneath the drawer bottom and outwardly of each of the drawer side walls. The flanges and ledges cooperate to permit the hinging-like rotation, to enable the drawer to hang substantially vertically downwardly.
U.S. Pat. No. 5,269,642 to Zoromski discloses a container loading and unloading system including a first set of cables attached to the front of the container, a second set of cables attached to the rear of the container, and a winch for alternately extending and retracting the cables by rotating a cross bar. A pair of substantially parallel rails is provided for supporting the bottom of the container, with a pivot bar located between and normal to both rails, and a yoke for supporting the pivot bar. To load the container—which may be a camper, a cargo box or a tool box—a cross bar is rotated in a first direction to extend the first set of cables and to retract the second set of cables, thereby pulling the container along the rail members onto a raised surface. The rails pivot along with the container on the pivot bar to assist in the loading operation. To unload the container, the cross bar is rotated in the opposite direction to retract the first set of cables and to extend the second set of cables, with the rails again pivoting about the pivot bar to lower the container onto the ground.
U.S. Pat. No. 5,641,262 to Dunlop, et al. discloses a hydraulic lift apparatus in general and to a hydraulically operated vehicular tailgate lift apparatus in particular.
U.S. Pat. No. 5,827,037 to Wilson, Jr. discloses a trailer chassis for receiving and transporting shipping containers having a platform extension fixedly attached to the rear end and with a liftgate that can be moved between a position level with the platform extension and ground level. The platform extension and the liftgate are each large enough for a loaded pallet handler to maneuver. This construction allows a forklift, pallet jack or other pallet handler to unload palletized cargo directly from the shipping container at various retail locations without the need for an elevated loading dock.
U.S. Pat. No. 6,077,024 to Trueblood discloses a modular cargo system for a truck-style vehicle including a cargo box having demountable pivot points on opposite sides near the front and bottom. Translating drives move along opposite sides of the truck bed and carry translating pivot blocks. Each translating pivot block has a pivotally-connected dual-link mechanism also pivotally connectable at the opposite ends to the demountable pivot points on the cargo box. The dual link mechanisms are of a length to allow the cargo box to sit on the ground behind the truck bed with the translating blocks moved near the tail end of the truck bed. By moving the translating blocks toward the cab end of the truck bed, the dual-link mechanisms articulate at an approximate end point, and the lower links are adapted to guide over the tail end of the truck bed while raising the front end of the cargo box in a manner that the front end of the cargo box clears the tail end of the truck bed. Further movement toward the cab end pulls the cargo box up into the truck bed. Mechanisms are provided for folding the link mechanisms so the cargo box may be fully boarded, and for ejecting the cargo box in several different ways.
U.S. Pat. No. 6,102,648 to Fretwell, et al. discloses a vehicle lift for use in conjunction with a vehicle to facilitate passengers boarding and leaving the vehicle. The vehicle lift has an improved driving mechanism for moving a platform between a stowed position to a deployed position. The driving mechanism includes a bidirectional motor which is mechanically coupled to a gear box which in turn is coupled to a pinion that is connected to a main sprocket. A longitudinal bracket is affixed to the underside of a top panel of the mounting enclosure and is located parallel to a longitudinal guide bar. At both ends of the longitudinal bracket are sprockets which are coupled by a loop chain. Accordingly, engaging the main sprocket with the loop chain moves the traveling assembly inward or outward with respect to the vehicle. The chain is immobilized by a manual spring biased locking mechanism to prevent the chain from moving linearly along the bracket. Therefore, when the motor is energized, it actuates the gear box which in turn drives the pinion, which in turn rotates the main sprocket to linearly travel on the chain moving the platform to a deployed position and visa verse.
U.S. Pat. No. 6,206,627 to Winter, et al. discloses a loading device for containers comprising a pair of loading units, each having a telescopic column supported on a bracket so as to be swivelled about a common swivel axis.

The platform can also move in the extracted position, between a lowered position and a raised position, by means of an articulated parallelogram linkage system. The movements of the platform are achieved by means of electrical actuators.
U.S. Pat. No. 6,666,643 to Heynssens discloses a frame with a pair of primary tracks positioned on a vehicle. A platform is connected by a plurality of flexible ties to a like plurality of hangers which travel along the primary tracks. An elevator mechanism winds the flexible ties onto reels to rise the platform toward the primary tracks and unwinds the flexible ties to lower the platform. Extension tracks can be removably aligned with the primary tracks to project beyond the vehicle. By moving the hangers onto the extension tracks, the platform can be removed from the vehicle and then lowered to the ground. The reverse process is employed to move the platform and objects thereon from the ground into the vehicle. The extension tracks with the hangers and platform attached thereto can be detached from the primary tracks and placed on a free standing frame to raise and lower the platform remote from the vehicle.
U.S. Pat. No. 6,811,068 to Johnson discloses a storage caddy having a slidable drawer on which items are stored. Items are presented for removal when the drawer is slid from the shell of the caddy. Items stored in a caddy with a hinged drawer, can be removed by breaking the drawer at the hinge to drop the item toward the ground for convenient and safe removal. A set of golf clubs stored in the caddy in the bed of a pick-up truck are slid from the shell on the drawer. The horizontal plane of the drawer is then broken at the hinge and the bottom of the golf bag moves toward the ground. The golf bag can then be easily lifted onto the shoulder or rolled away. The caddy positions heavy items for easy removal preventing undue stress or injury on those retrieving items from the caddy.
U.S. Pat. No. 7,111,884 to Johnson discloses a storage compartment and integrated tailgate work surface. The storage compartment is easily retrofitable to any standard or light duty pick-up truck bed. A parallel linkage mechanism and integrated power unit can raise and lower the storage compartment without rotation, thereby keeping objects in an initial desired orientation and placement within the compartment. The parallel linkage system also facilitates adjustment of the integrated tailgate work surface to convenient working heights.
U.S. Pat. No. 8,393,665 to Villano, et al. discloses a pick-up truck bed toolbox system utilizing a tool storage box which, in its stored, stationary position, rests on the floor of the bed of a pick-up truck such that it is parallel to the side wall of the truck. Electric motors, which can be remotely operated, are utilized to rotate dual, upstanding screw shafts which are connected via laterally extending cantilever arm members to the front and rear ends of the toolbox. The screw shafts raise the toolbox from its resting position on the floor of the bed of the pick-up truck, to an elevated position over the floor, and the shafts then operate to move the arm members laterally to extend the tool box to a position passed the side wall. The screw shafts can then be activated to lower the tool box to a lowered position outside the truck, adjacent to and alongside the sidewall, thus providing easy and ready access to the toolbox. The same system is utilized to return the toolbox from this lowered position outside the truck, to the floor of the truck bed.
U.S. Pat. No. 8,403,615 to McGlinn, et al. discloses a vehicle lift barrier adapted to be mounted to vehicle lifts and the like that assist in loading and unloading cargo and provide a storage environment in which cargo is less likely to migrate from a cargo area into a passenger seating area or compartment. A barrier composed of a barricade is mounted to a vehicle lift, in some cases example by mounting the barrier to a generally vertical post, mast or the like or mounting the barrier to a lift platform, allowing the lift to operate normally while the barricade obstructs all or a substantial portion of the passage between the motor vehicle storage/cargo area and the passenger area. Where the barrier is mounted to a vertical post or the like on a vehicle lift, cut-out bracketing can be used to mate with the outer cross-sectional shape of the post to inhibit pivoting of the barrier about the post. Other bracket profiles can be used to enhance the barrier's protective advantages. A wrap-around sheet metal bracket configuration creates two flanges per bracket to reinforce bracing and to provide securing belt mounting points for a given vehicle lift. Such barriers can be used in motor vehicles with rear and/or side access-ways where vehicle lifts typically are provided and do not require special tie-downs or other cargo securing means, making such devices especially useful in vehicles that might serve a number of different users and/or that might transport a variety of types of cargo and/or mobility devices.

SUMMARY OF THE INVENTION
The present invention is defined by the appended claims with specific embodiments being shown in the attached drawings. For the purpose of summarizing the invention, the invention relates to an improved cargo handling device for a vehicle. The cargo handling device comprises a base extending between a lower end and an upper end. The lower end of the base is coupled to the cargo surface. A lower track extends between a proximal end and a distal end. The proximal end of the lower track is coupled to the base. An upper track extends between a proximal end and a distal end. The proximal end of the upper track is coupled to the base. A traveler has a lower track receiver and an upper track receiver. The lower track receiver of the traveler slidably engages the lower track between the proximal end and the distal end of the lower track. The upper track receiver of the traveler slidably engages the upper track between the proximal end and the distal end of the upper track. A storage unit has a lower track receiver and an upper track receiver and extends between a proximal end and a distal end. The lower track receiver of the storage unit slidably engages the lower track between the proximal end and the distal end of the lower track. The upper track receiver of the storage unit slidably engages the upper track between the proximal end and the distal end of the upper track. A linear actuator engages the base and the traveler for displacing the traveler along the lower track and the upper track between the proximal end and the distal end of the lower track and the upper track. A telescoping actuator defines a contracted length and an extended length. An upper actuator pivot pivotably couples the telescoping actuator to the traveler. A lower actuator pivot pivotably couples the telescoping actuator to the storage unit. The contracted length in the telescoping actuator maintains the traveler abutting the proximal end of the storage unit during displacement of the traveler between the proximal end and the distal end of the lower track and the upper track. The extended length in the telescoping actuator displaces the storage unit from the traveler upon the traveler positioned at the distal end of the lower track and the upper track. The extended length defines a horizontal displacement and a vertical displacement of the storage unit from the traveler for positioning the storage unit adjacent the surface. A cargo receiver is coupled to the storage unit for engaging the cargo.
In a more specific embodiment of the invention, the linear actuator includes a motor and a threaded rod. The motor is coupled to the base and provides a rotational force. The threaded rod is coupled to the motor for rotating the threaded rod with the rotational force. A threaded aperture is in the traveler for threadably engaging the threaded rod. The rotational force causes the traveler to be linearly displaced between the proximal end and the distal end of the lower track and the upper track.
In one embodiment of the invention, the lower track includes a base wall, a first side wall and a second side wall for defining a general C-shape. The base wall is coupled to the cargo surface. The first side wall includes a first elongated slot. The second side wall includes a second elongated slot. The upper track includes a lower wall, a first side wall, a second side wall and an upper wall. The traveler includes a first frame, a second frame and an upper cross frame. The first frame is positioned adjacent to the first side wall of the lower track and the first side wall of the upper track. The second frame is positioned adjacent to the second side wall of the lower track and the second side wall of the upper track. A traveler pin is secured to the first frame and a second frame and traverses the first elongated slot and the second elongated slot. The threaded aperture is in the traveler pin. The traveler pin slidably engages along the first elongated slot and the second elongated slot during displacement of the traveler between the proximal end and the distal end of the lower track and the upper track.
In another embodiment of the invention, the lower track includes a base wall, a first general T-shape and a second general T-shape. The first general T-shape is coupled to the base wall for defining a first I-beam. The second general T-shape is coupled to the base wall for defining a second I-beam. The first I-beam and the second I-beam define a beam channel there between. The base wall is coupled to the cargo surface. The upper track includes a lower wall, a first side wall, a second side wall and an upper wall. The traveler includes a first rear frame, a second rear frame, an upper rear cross frame and a lower rear cross frame. The traveler includes a first front frame, a second front frame and a lower front cross frame. A primary frame bar couples the first rear frame with the first front frame. A secondary frame bar couples the second rear frame with the second front frame. The first rear frame is positioned adjacent to the first I-beam of the lower track and the first side wall of the upper track. The first front frame is positioned adjacent to the first I-beam of the lower track. The second rear frame is positioned adjacent to the second I-beam of the lower track and the second side wall of the upper track. The second front frame is positioned adjacent to the second I-beam of the lower track. A rear traveler arm is secured to the lower rear cross frame and extends into the beam channel. A front traveler arm is secured to the lower front cross frame and extends into the beam channel. The threaded aperture defines a rear threaded aperture in the rear traveler arm and a front threaded aperture in the front traveler arm.
The invention is also incorporated into the method of activating a linear actuator engaging a base and a traveler. The traveler is displaced from a proximal end and to a distal end of a lower track and an upper track by the linear actuator. A storage unit is displaced from the proximal end and to a cantilever position above the surface and beyond the distal end of a lower track and an upper track by coupling with the traveler. The linear actuator is deactivated upon the traveler positioned at the distal end of the lower track and the upper track. A telescoping actuator is activated that engages the traveler and the storage unit. The storage unit is displaced from the traveler including a horizontal displacement and a vertical displacement by the telescoping actuator. The telescoping actuator is deactivated upon positioning the storage unit adjacent the surface.
The foregoing has outlined rather broadly the more pertinent and important features of the present invention in order that the detailed description that follows may be better understood so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention.
