Truck bed extension device

Abstract

A truck bed extension device (10) for use with a truck (12) having a cargo bed structure, wherein the device (10) allows for carrying items which extend beyond or overhang the bed structure. The device (10) comprises a deck (24); a support structure (26); and a signaling system (28). The deck (24) is horizontally adjustable relative to the bed structure so as to allow for achieving a desired spacing therebetween. The deck (24) is also vertically offset when unloaded so as to be substantially flush when loaded. Because the device (10) or the load carried thereon may obstruct viewing of the truck's existing brake and turn signals, the signaling system (28) repeats these signals where they are more visible. A second embodiment of the device (110) provides a hitch structure (170) for coupling the truck with a trailer via the device (110).

Description

[0001] 1. Field of the Invention[0002] The present invention relates broadly to devices for enhancing the cargo carrying or hauling ability of a conventional truck. More particularly, the present invention concerns a truck bed extension device comprising a supported deck positionable substantially adjacent to and substantially flush with an end of an existing cargo bed structure of a conventional flatbed or pickup truck so as to allow for safely and securely carrying or hauling cargo items which extend beyond or overhang the existing bed structure.[0003] 2. Description of the Prior Art[0004] It is often desirable to transport an item using the existing cargo bed structure of a conventional flatbed or pickup truck. Unfortunately, the item is sometimes longer than the truck is able to safely and securely accommodate. Certain types of items, including, for example lumber or piping, may simply be allowed to extend beyond or overhang the existing bed structure. Other types of items, howe...

Problems solved by technology

Unfortunately, the item is sometimes longer than the truck is able to safely and securely accommodate.

Other types of items, however, including, for example, snowmobiles, all terrain vehicles, and motorcycles, cannot safely or securely be allowed to overhang the existing bed structure.

Tailgates, however, are typically not designed to support significant amounts of weight, and may bend or be otherwise damaged under heavy loads.

Unfortunately, these prior art devices suffer from a number of disadvantages, including, for example, that they provide only a substantially one-dimensional linear support structure which is not suitable for resting and supporting wheels or legs upon.

Furthermore, horizontal positioning of the prior art devices is typically not adjustable relative to the existing bed structure, and the support structure is typically spaced a substantial distance apart from an end of the existing bed structure, meaning that only items of a certain minimum length can be supported.

Additionally, the prior art devices or the loads carried thereon typically obstruct views of brake lights, turn signals, and license plates which the law requires trucks and other vehicles to display.

Such obstruction can potentially result in accidents where following drivers, unable to see the signaling lights of the truck, are left unaware of and unable to respond to braking or turning actions.

Additionally, the prior art devices typically substantially interfere with access to an existing hitch structure commonly associated with a lower rear portion of the truck, thereby preventing use of the existing hitch structure to couple a trailer or other vehicle to the truck for towing.
