Truck bed extender

## Abstract

An extender for a bed of a truck, wherein the extender comprises a frame that has front end, a rear end and sides. At least one, and preferably two, spaced apart connector brackets extend outwardly away from the rear end of the frame. The connector brackets are designed to rest upon an end portion of the truck bed when the truck's tailgate has been removed. The connector brackets are preferably bolted into the truck bed, but may be frictionally engaged therewith. A strut extends downwardly from the frame and is connected to a rearwardly extending longitudinal support. The support is secured to the truck's trailer hitch. The extender is therefore supported by both the connector brackets and the hitch. The length of the strut is vertically adjustable to allow the extender to be secured to any type of truck. The longitudinal support is also slidably adjustable onto the trailer hitch to provide for the extender to be secured to any type of truck. The frame preferably is formed with a pair of spaced-apart wheel wells so as to receive a pair of wheels of a vehicle loaded onto the truck bed. The frame may be provided with a pair of ramps to assist in loading of the truck and with an extended hitch to allow a trailer to be connected to the truck.

## Background
BACKGROUND OF THE INVENTION
1. Technical Field
This invention generally relates to automotive vehicles. More particularly, the invention relates to an extender for a truck bed. Specifically, the invention relates to an extender that is secured to both the truck bed and to a hitch mounted on the truck and that is capable of supporting a heavy weight thereon, such as a six-wheeled all terrain vehicle.
2. Background Information
There are many new mid-size to large trucks where the cab is extended to accommodate an extra row of seats. This design change in the vehicles tends to take up some of the exterior space in the truck bed and thereby restricts the load that can be carried on the bed. If the truck is used to transport small vehicles such as small all terrain vehicles or snowmobiles, then the tailgate of the truck can be left open. The open tailgate provides a few extra feet of truck bed support for these smaller vehicles. However, heavier and longer vehicles, such as six-wheeled all terrain vehicles are common on farms and are often used for hunting trips. These larger vehicles are much heavier and because of the increased weight can potentially damage the truck's tailgate as they are loaded onto the bed. The weight of the larger vehicles can also damage the tailgate during transportation.
There is therefore a need in the art for a truck bed extender that allows for the loading and transportation of heavy vehicles.
SUMMARY OF THE INVENTION
The device of the present invention is an extender for a truck bed where the truck's tailgate is removed. The extender comprises a frame that has front end, a rear end and sides. At least one, and preferably two, connector brackets extend outwardly away from the rear end of the frame. The brackets rest upon an end portion of the truck bed when the truck's tailgate has been removed. The connector brackets are preferably bolted into the truck bed, but may be frictionally engaged therewith. A strut extends downwardly from the frame and is connected to a longitudinal support that extends rearwardly therefrom and is designed to engage a hitch mounted on the truck. When secured in place, the extender is supported by both the connector brackets and the hitch. The length of the strut is vertically adjustable to allow the extender to be secured to any type of truck. The frame is provided with a pair of spaced-apart wheel wells that allow it to receive a pair of wheels of a vehicle loaded onto the truck bed. The frame is preferably also provided with a pair of ramps to assist in loading of the truck and with a secondary hitch to allow a trailer to be connected to the truck.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-6, there is shown a truck bed extender in accordance with the present invention and generally indicated at 10. Extender 10 comprises a generally rectangular frame 12 that includes a front bar 14, a rear bar 16 and two side bars 18, 20 that are connected to one another to form a generally rectangular support. A plurality of crossbars 22, 24, 26 connect the front and rear bars 14, 16 together and act both to strengthen and stabilize frame 12.
A pair of connector brackets 28, 30 extend rearwardly away from rear bar 16 and are substantially coplanar with the upper surface 16a of rear bar 16. Connector brackets 28, 30 preferably are integrally formed with rear bar 16, but may alternatively be secured to rear bar 16 by welding, bolting or other suitable connection means. Each connector bracket 28, 30 includes a plurality of spaced apart holes 32 therein. Holes 32 are designed to receive a plurality of bolts (not shown) therethrough to secure frame 12 to the bed of a truck as will be hereinafter described.
A pair of ramp supports 34, 36 are connected to front bar 14 of frame 12, preferably by welding. As seen in FIG. 5, ramp supports 34, 36 angle downwardly from the upper surface 14a and toward the ground.
A pair of support brackets 38, 40 are connected between front and rear bars 14, 16. Support bracket 38 is disposed between side 18 and cross bar 22, while support bracket 40 is disposed between side bar 20 and cross bar 26. Support brackets 38, 40 are substantially identical, each being of an open U-shape (FIG. 5) and including a flat middle portion 42 with inclined portions 44 and 46 extending upwardly from either end thereof. Middle portion 42 extends below the plane of frame 12. Side bar 18, cross bar 22 and portions of front bar 14 and rear bar 16 form a first wheel well 48 that has support bracket 38 therein. Side bar 20, cross bar 26 and portions of front and rear bars 14, 16 form a second wheel well 50 that has support bracket 40 therein. First wheel well 48 is adapted to receive a first ATV tire therein and second wheel well 50 is adapted to received a second ATV tire therein.
Referring to FIGS. 5-7, there is shown a longitudinal support 52 that has a first end 52a that is configured to be received within a receiver hitch 54 of a truck 56. A second end 52b of support 52 protrudes through the aperture of a short horizontal hollow support member 58 for attachment of an optional hitch ball 82. Hitch ball 82 is secured to support 52b by any suitable conventional means.
A telescoping strut 62 extends upwardly from the upper surface of support 52. Strut 62 is selectively adjustable to vary the distance between support 52 and connector bracket 28, 30 and to thereby allow extender 10 to be mounted to a variety of different truck bodies. A plurality of support brackets 64 extend between an upper portion 62a of strut 62 and cross bars 22, 24 and 26.
A pair of U-shaped side frames 66, 68 may optionally extend downwardly from the bottom surface of side bars 18, 20, respectively. Side frames 66, 68 are provided to allow for easier access into the truck bed and act as a ladder for entry thereto.
FIG. 1a shows extender 10 where the optional side frames 66, 68 and hitch 60 are removed.
The extender 10 in accordance with the present invention is used in the following manner. The bed bolts (not shown) are removed from the truck 56 leaving a plurality of empty holes 70 in the bed 72 of the truck where the mounting bolts (not shown) were engaged. The relative distance “A” and “A′” (FIGS. 3&4) between the connector brackets 28, 30 and the longitudinal support 52 is adjusted to accommodate different truck and hitch 56, 54 combinations. This is accomplished by telescoping the lower portion 62b of strut 62 either into or out of the upper portion 62a thereof until the correct distance exists. FIG. 3 shows an instance where substantially all of the lower portion 62b of strut 62 is retained within the bore of the upper portion 62a. FIG. 4 shows an instance where some or all of the lower portion 62b extends outwardly from upper portion 62c. Consequently, the distance “A′” is longer than the distance “A”. A mechanism, or any other suitable conventional means, may be provided to lock the upper and lower portions 62a, 62b in place. FIG. 5 and FIG. 7 illustrate multiple aperture pairs 62c in at least the lower portion 62b, or both the lower portion 62b and upper portion 62a, which may accept fasteners (not shown) as are conventionally found in strut locking mechanisms.
Once the correct distance “A” or “A′” has been set, the first end 52a of the extender's longitudinal support 52 is slidingly engaged in the aperture 74 in the truck's receiver hitch 54 and, simultaneously, connector brackets 28, 30 are slid over the upper surface of truck bed 72. Support 52 is then secured to hitch 54 in the conventional manner. Furthermore, one or more bolts 76 are inserted through one or more holes 32 in brackets 28, 30 and into correspondingly aligned holes 70 in bed 72. Extender 10 is now in condition for loading of a vehicle into truck 56.
A pair of ramps 78 is placed between ramp supports 34, 36 and the ground. The vehicle to be loaded onto truck 56 is moved up ramps 78 and onto bed 72. In the case of an all terrain vehicle, one or more pairs of wheels (not shown) rest on bed 72 and a pair of wheels 80 of said vehicle is received within wheel wells 48, 50 and rest upon support brackets 38, 40. Because the middle sections 46 of support brackets 38, 40 are recessed with respect to frame 12, the tendency of the vehicle to roll off bed 72 is substantially reduced. The vehicle may be secured to the truck 56 by a plurality of ropes and cables (not shown).
The optional hitch 60 is provided with a ball 82 to allow for attachment of any other towed vehicle (not shown).
A second embodiment of the extender is shown in FIG. 8 and is generally indicated at 210. Extender 210 is substantially identical with extender 10 except for the location of connector brackets 228, 230. Connector brackets 228, 230 extend outwardly from rear bar 216 proximate side bars 218, 220 and are provided with a rubber covering 290. This combination allows brackets 228, 230 to frictionally engage the truck bed and side walls (not shown). The longitudinal support 252 is connected and supported by the truck hitch (not shown) and the optional hitch 260 extends out forwardly from extender 210 and beyond front bar 214.
It will be understood that the first end 52a of longitudinal support 52 can be manufactured to connect to any other type of trailer hitch without departing from the spirit of the present invention. Furthermore, second end 52b of longitudinal support 52 can act directly as a receiver-type hitch instead of the ball type hitch connector shown in the attached figures.
In the foregoing description, certain terms have been used for brevity, clearness, and understanding. No unnecessary limitations are to be implied therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.
Moreover, the description and illustration of the invention is an example and the invention is not limited to the exact details shown or described.
