This invention relates generally to vehicles, and in particular to flatbed trucks.
The bed of a flatbed truck generally has no sides (other than at the front to protect the truck's cab, or to the extent the cab or toolbox, for example, creates a front side). A pickup truck may become a flatbed truck by removing its existing bed and side panels (or ordering the truck without the normal bed and side panels), and then attaching a flatbed to the truck's chassis. On some flatbed trucks, the wheels and truck underside are exposed (un-skirted). In other instances, it is desirable to install a skirt on each side of the flatbed truck, to cover the rear wheels or for aesthetics. Flatbed and skirt assemblies are custom made for the particular model of pickup truck on which they are to be installed.
In accordance with the teachings of the present invention, in one embodiment a flatbed assembly is provided, comprising: a flatbed comprising a bed floor, a left side, and a right side, the flatbed further comprising a multiplicity of left-side flatbed fastener holes proximate the left side and a multiplicity of right-side flatbed fastener holes proximate the right side; an engagement assembly comprising a multiplicity of fasteners; and a left-side skirt and a right-side skirt, each skirt comprising a wheel well and a multiplicity of skirt fastener holes, the left-side skirt fastener holes matching the left-side flatbed fastener holes and the right-side skirt fastener holes matching the right-side flatbed fastener holes; wherein the engagement assembly couples the skirts to the flatbed by one each of the fasteners positioned in the respective matching left-side skirt hole and left-side flatbed hole, and one each of the fasteners positioned in the respective matching right-side skirt hole and right-side flatbed hole.

Important technical advantages are provided by the present invention. In particular, and without limitation, by providing different skirts that have wheel wells located to accommodate various rear axle positions, but which have the same fastening locations, a single flatbed model may be used on multiple truck brands, thus reducing the need for custom flatbed assemblies for each truck brand.
Another important technical advantage of the present invention is that it allows skirts to be coupled to flatbeds with nuts and bolts, thus allowing for easy installation, removal, and re-use of the flatbeds and the skirts, without the need for welding for attachment and without the need for weld grinding for removal.
Reference is made in the description to the following briefly described drawings, which are not drawn to scale, and in which like reference numerals indicate like features:
Also shown in
The left and right-side skirts may extend longitudinally from their respective wheel wells all the way toward the front of the flatbed 10 (for example proximate the truck cab or cab protector 16) or only some of the way. In particular, the skirts have a front edge 26 in front of the wheel well 14. The front edge 26 may be spaced apart from wheel well 14 as desired. In the embodiment shown in
With the present invention, different sets of left-side and right-side skirts (the skirts discussed above) are provided for different model trucks (for example, Ford, GM, and Dodge trucks (Ford, GM, and Dodge are registered trademarks of their respective owners)), with the difference in the sets being related to the wheel wells. In particular, different model trucks have different rear axle positions, and the wheel wells in each respective set are positioned on the left-side and right-side skirts to be substantially longitudinally centered on the axle and to accommodate the wheels for the particular truck model on which they are to be installed. However, other than the wheel well position (and possibly the position or shape of the wheel well couplers), the skirts from the different sets are otherwise substantially the same, and couple to the flatbed in the same manner. Therefore, one flatbed model may be used with the skirts for multiple truck models, as the skirts of each different set attach to the flatbed in the same way and in the same locations. In some embodiments, it may be appropriate to change the location of wheel well fastener holes 51, or the length or angle of wheel well couplers 44, from skirt-set to skirt-set, to accommodate the different wheel well locations and coupling of the wheel well couplers 44 to the flatbed 10 (with fasteners in fastener holes 48). However, in other embodiments, the locations of holes 51 with respect to the wheel well center and the length and angle of wheel well couplers 44 are substantially the same from set to set. Furthermore, additional holes 48 may be made in the flatbed 10 to accommodate the coupling of wheel well couplers 44 in different positions on flatbed 10, to accommodate differences brought about by the different wheel well (and holes 51) positions. Also, more than one hole 50 may be made at one or both ends of wheel well couplers 44 to accommodate for differences brought about by the different wheel well (and holes 51) positions. With these accommodations, the same wheel well couplers 44 may be used from set to set.
The ability to use a single flatbed model with multiple different skirt sets is an important advantage of the present invention because, among other things, it reduces inventory and manufacturing costs. Similarly, the ability to use the same coupling members from set to set is an important advantage of the present invention.
Also provided is a process for assembling a flatbed assembly for a truck having a particular rear axle location (the axle location defines a left-side wheel location and a right-side wheel location). In this process, a flatbed 10 according to the teachings herein is attached to the truck. Also, the multiple skirt sets discussed above are provided, and a skirt set is selected that has left-side and right-side wheel well positions that match that of the left-side wheel location and the right-side wheel location of the particular truck model. Then, the skirts are coupled to the flatbed by positioning fasteners in the respective matching left-side skirt holes and left-side flatbed holes, and by positioning fasteners in the respective matching right-side skirt holes and right-side flatbed holes. The process may further include coupling the wheel wells of the selected skirt set to the flatbed. Also, the process may include coupling a toolbox to the flatbed so that the toolbox is between one of the skirts and a cab of the truck on which the flatbed is attached. A toolbox may be coupled on one or both sides of the truck.
In particular embodiments, the flatbed and skirts may me formed from or covered with diamond plate sheet steel. Single or multiple sheets may be used, with the multiple sheets suitably joined, for example by welding. The sheet(s) may be bent to form sides and lips, or separate sheet pieces may be suitably joined to form the sides and lips.
In some embodiments, one or more of the fasteners and fastener holes may be located so they are “hidden” from view (except by looking underneath).
In some embodiments, one end of L-brackets 42, or one end of the wheel well couplers 44, or one end of the front couplers 54 is welded to the flatbed 10 or to the skirt, while fastening the other end with fasteners. This option may speed up installation and removal of the skirts. Also, in some embodiments the fastener nuts may be formed or suitably fixed in place (for example by welding our glue), to allow easy installation of the fasteners through the respective holes and in threaded engagement with the in-place nuts. Furthermore, the nuts (whether separate or fixed in place) may be made of any suitable material, including metal or nylock, and rubber washers may be used to reduce rattle.
As used herein, coupled and couples include direct connection or indirect connection through one or more intermediate members.
Particular features of the example embodiments may be used with, added to, or substituted in the other example embodiments.
Although the present invention has been described in detail, it should be understood that various changes, alterations, substitutions, additions, and modifications could be made without departing from the intended scope of the invention, as defined in the following claims.
