Preferred embodiments of the invention are described in detail below with reference to the attached drawing figures, wherein:
The drawing figures do not limit the present invention to the specific embodiments disclosed and described herein. The drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the preferred embodiment.
Turning now to the drawings, a tractor-mounted cargo container 20 is illustrated in
In more detail, the main body 24 is preferably formed of molded synthetic resin material, although other suitable materials and fabrication techniques may be used. The main body 24 generally includes a bottom wall 36, a pair of opposed sidewalls 38 and 40, and front wall 42. The bottom wall 36 has a series of elongated, laterally spaced apart, upstanding stiffening ribs 44 and a series of drainage holes 46 between the ribs 44. The bottom wall 36 has rounded side margins which merge with the upstanding side walls 38, 40. The particular configuration of the main body 24 may be varied and still fall within the scope of the present invention; however, it is important that the main body 24 presents an open rear section as further defined below.
The sidewalls 38, 40 are preferably mirror opposites of each other, and each has an elongated, inwardly-extending ledge 48 as well as a pair of inwardly-extending, generally rectangular protrusions 50 extending upwardly from the bottom of the respective sidewalls to merge with ledge 48. Additionally, mated rectangular protrusions 52 extend upwardly from the ledge 48. As best seen in
The front wall, bottom wall 36 and sidewalls 38, 40 are preferably equipped with mounting structure 62 designed to maintain the panel 26 in its alternate upright and horizontal orientations. The structure 62 includes a generally U-shaped rear margin 64 having a pair of laterally spaced apart, open-top, rectangular connection blocks 66 along the lower horizontal extent thereof, along with an inboard, generally U-shaped, inwardly-extending rib 68. As best seen in
Front wall 42 merges with bottom wall 36 and sidewalls 38, 40 at rounded junctures, and also has a ledge 76 which extends between and forms a continuation of the sidewall ledges 48. As best seen in
The alternate use panel 26 is of integrally molded, synthetic resin construction, although other suitable materials and fabrication techniques may be used. The panel 26 preferably has a generally rectangular main panel section 82 as well as an obliquely oriented tool-holding section 84. The panel section 82 is equipped with a plurality of inwardly-extending strengthening ribs 86 as well as a series of upper openings 88. The lower margin of the panel section 82 includes a pair of laterally spaced apart connection tongues 90. The inner face of the panel section 82 has a pair of marginal connecting lugs 92 with inwardly projecting segments 94 (
The main body 24 and panel 26 preferably present opposed interengaging surfaces in each of the alternate positions of the panel 26, wherein the surfaces are specifically configured to restrict bowing out of the side walls when the container 20 is filled with a load. More particularly, one of the surfaces faces outwardly and is defined in each side wall and another surface is defined in the panel to face inwardly in an opposed relationship to the respective one of the surfaces, wherein outward deflection of the side walls is restricted by interengagement of the opposed surfaces when the panel is in the alternate positions thereof. In the preferred embodiment, the opposed surfaces are defined by certain components of the mounting structure 62. When the panel is in the upright tailgate position, the two-piece clips 70 cooperate with the lugs 92 to present the opposed surfaces. As perhaps best shown in
The auxiliary containers 28 and 30 are preferably identical and are designed to be detachably secured to the sidewalls 38, 40 of the main container body 24. Again, these containers are integrally molded of synthetic resin material, although other suitable materials and fabrication techniques may be used. Each auxiliary container preferably has substantially planar inner walls 98, sidewalls 100, 102, outboard wall 104, and apertured bottom wall 106. Each of the inner walls 98 has a pair of spaced apart, downwardly-extending connection hooks 108. The principles of the present invention are equally applicable to alternatively dimensioned and configured auxiliary containers. Moreover, certain aspects of the present invention encompass only one removable auxiliary container or none at all.
The hitch assembly 32 is preferably formed of metal (although other suitable materials are within the ambit of the present invention) and has a lowermost connection plate 110 having a forward, upturned lip 112 and an elongated slot 114. An upstanding, generally rectangular tube 116 is secured to the plate 110 via coupler 118. The tube 116 has a pair of side marginal holes 117, and supports a rearwardly-projecting brace 120 connected via coupler 122. The connection plate 110 preferably includes a plurality of mounting holes spaced apart in a fore-and-aft direction so that the coupler 118 is adjustably positionable on the plate 110. With the container 20 being supported on the tractor 22 in a cantilevered fashion, such an arrangement permits the user to adjust the center of gravity for the container 20 (and the load carried thereon), which can provide numerous advantages during operation (e.g., impact traction for the tractor 22). Furthermore, the connection plate 110 is preferably provided with a rearmost secondary hitch opening spaced rearwardly from the mounting holes of the coupler 118. This opening permits additional components (e.g., a trailer) to be connected to the tractor 22 via the hitch assembly 32.
The tube and the brace 120 cooperatively form a tractor accessory support, which can be variously configured depending upon the accessory to be supported on the tractor thereby. In the illustrated embodiment, the support is particularly designed to support the components 24-30. However, the principles of the present invention are equally applicable to use of the hitch assembly 32 to support other types of components on the tractor 22.
The tractor draw plate 34 has an upstanding segment 124 as well as a rearwardly-projecting segment 126 having aperture 128 formed therein and adapted to receive a connecting bolt 129. The hitch assembly 32 is particularly designed for use with other tractor designs having alternatively configured draw plates. Furthermore, the hitch assembly 32 includes a pair of flexible cables 130 each having connection hooks 132 at opposite ends thereof. The illustrated cables are adjustable length straps that can be selectively tightened by the user. However, the principles of the present invention are equally applicable to alternative cable designs, such as elastic straps or so-called bungee cords.
In use, the main body 24 of container 20 is secured to tractor 22 by means of hitch assembly 32. In particular, the plate 110 is first placed beneath segment 126 of draw plate 34, with lip 112 engaging the forwardly facing surface of the lower margin of upright segment 124. The plate 110 is then secured by means of bolt 129, which extends through aperture 128 and slot 114. Each cable 130 is then secured in place by inserting one of the hooks 132 into an available opening in the draw plate 34 (typically there are many) and the other hook into the corresponding hole 117 in the connector tube 116. The cables 130 are preferably oriented to extend laterally in opposite directions to prevent side-to-side movement of the main body 24. The main body 24 is then (or has previously been) secured to tube 116 by inserting the latter into socket 78 forming a part of front wall 42. This is perhaps best illustrated in
The alternate use panel 26 is affixed to the body 24 in either of its alternate positions. The panel 26 may be used to close the rear opening 74 of the body 24, or it may be oriented horizontally substantially within the confines of the body 24. The first alternative position is depicted in
If it is desired to place the panel 26 in its horizontal shelf orientation (
The container 24 and auxiliary containers 28, 30 can be loaded with tools and/or supplies, for easy transport to a work site. If desired, elongated tool handles can be placed in spanning relationship to the sidewalls 38, 40, by placing the handles within the arcuate regions 56a. These tools can then be secured for travel by the use of bungee cords or similar expedients attached to the forward openings 54.
The hitch assembly 32 is capable of mounting to essentially any standard tractor draw plate 34. That is, the draw plates of different manufacturers are not standardized, and therefore a hitch operable with one type of tractor will not normally be usable with other tractors. The present overcomes this difficulty, however, by provision of the slotted plate 110 which accommodates the bolt locations of virtually all different draw plates. The cables 130 enchance the secure connection between the container 20 and the tractor 22. Thus, a truly universal hitch assembly is provided.
