Description
FIELD OF THE INVENTION
This invention relates to an endgate asse~bly ~or a truck box, particularly an agricultural trucX bo2 such as a grain bo~.
_CKGROUND OF THE IN~ENTION
The conventional grain box endgate is oE
sophisticated design, since it must per~orm a variety of ~unctions. It must of course extend fully across the entire O width of the truck box, in order to hold the grain during transportation. The endgate must provide a res-tricted ~low during the unloading process. It must also be heavy and strong enough to withstand the considerable weight of a ~ully loaded grain box, when same is hydraulically hoisted during an unloading operation.
It has been found that a conventional three-piece design endgate adequately performs the above funckions. Such three-piece endgate typically comprises two side panels, each hinged to one of the side walls o~ the grain box. The side panels and their hinges are designed such that the side panels may be swung outwardly when it is necessary to fully open the endgate. A center panel is also provided, which is typlcally hinged to one of the side panels and latched to the other. A grain gate is generally provided in the center panel, so as to allow egress of the grain during the unloading process. A four-piece endgate, having upper and lower center doors, is also known. ~ts upper center door may be opened, allowing an operator to more safely en-ter -the grain box durin~ the unloading process.
Typically, the grain box is no-t used solely Eor transporting grain. It is also often used -to transport agricul-tural e~uipment, such as straight-cutt:ing headers, to the location at which -the grain is -to be cut and loaded.
Such assemblies are often longer than the length oE -the truck box. Thus a further function o~ an endgate is that i-t must be fully openable to allow for the accommodation and transportation of such equi~ment.
It has been found that a grain box equipped with an endgate of conven-tional design is not convenient for the purpose oE transporting agricultural equipment which is longer than the grain box. The conventional endgate may be swung outwardly, one-third to one side of the truck bo~, and two-thirds to the other side, and stored against the outer sides of the truck box. However, during transpor-tation, particularily at highway speeds, such a configuration results in the sides of the endgate catching in -the wind, vibrating and rattling. Further, since in such a position the portions of the endgate are supported only by hinges, with time, wear and misalignment of the hinges occurs.
Some of these disadvantages can be avoided by removing the conventional endgate from its hinges, and then replacing same after transportation of the equipment is complete. However, such removal and re-installation is tedious, time consuming and labour intensive, being typically a three-man job in view of the size and weight of t~e heavy endgate panels. ~ccordingly, removing the endgate in order to transport equipment has its own disadvantages.
Custom combiners and others who do work during a single season at several locations across Canada and in the United States, having truck boxes equipped wi-th conven-tional endgates, are thus faced with the task of adop-ting either of the above two disadvantageous procedures, in order to transpor-t their equipment, each time they move to a new job location.
SU~SMARY OF THE INVENTION
It has been found that lengthy agricultural equipment may be transported in grain boxes without the disadvantages associated with conventional endgates, by providing the grain box with an inwardly swinglng endgate, whereby the endgate may be stored against one of the truck box side walls. Such endgate in its preferred embodiment also retains all of the standard features required of a grain box endgate.
Accordingly, an endgate assembly is provided in accordance with the present invention, which comprises an endgate structure capable of being connected to at least one side wall of the truck box and pivotably movable about a vertical axis, and means capable of maintaining the endgate structure in a closed position. The endgate structure is capable of being swung inwardly from a closed position, in which the endgate structure extends substantially across the back end o~ ~he ~ruck box, to an open position in which the endgate structure is substantially parallel to and closely adjacent to at least one of the side walls, whereby the interior oE the truck box is substantially unobstructed.
The endgate is preferably a unitary structure pivotably movable about a ver-tical axis, from its closed position through approximately a right angle to an open position next to one of the side walls.
The pre~erred embodiment of -the invention may be produced by welding rigid members to the top and bottom edges of the side panels of a conventional three or four-piece endgate, by removing the conventional side panel hinges, by adding stop means to one of the side walls of the truck box, and by mounting the now integral endgate onto the other side wall on hinges which allow for inwardly pivotal movement. An endgate thus produced retains all of the necessary functions and features of a conventional endgate~
In addition, the endgate assembly made in ~0 accordance with the present invention has the added advantages o~ speedily and e~fortlessly converting the grain box into an improved means ~or transporting agricultural equipment longer in length than the grain box itself, by merely swinging the endgate inwardly against one side of the truck box. Thus, the time and effort associated with moving an re-installing the endgate is avoided. Further, the hinge wear and noise associated with transporting equipment with the endgate stored against t'ne outer walls of -the truck box is eliminated.
The endgate assembly of -the present invention also possesses other advantages over conventional endgates. The integral aspect of the endgate makes it stronger than conventional three or four-piece endgates. In particular, such an integral endga-te, w~en positively restrained by the preferred stop means, is strong enough to withstand the weight of a full box-load of grain, without having to resort to auxiliary bracing means, such as diagonal bracing bars, extending at an angle between the endgate and each side wall.
The subject endgate is also more easily opened and closed in tight areas, since no clearance behind the end of the truck bed is necessary in order to open the endgate.

DETAILED l~ESCRIPTION OF THE P~EFERR~D EMBODIrlENI
Figure 1 illustrates a truck box generally designated as 10, having side walls 11 and 12, front wall 13 and endgate structure 14 (here.inaEter "endgate") pivotably mounted on side wall 12 along vertical axis 15, by means of hinge means 16. Stop means 17 and latch means 18 are provided at -the end of side wall :Ll. Endgate 14 is shown in a partially open position.
Figure 2 indicates tha-t endgate 14 may be pivoted inwardly about hinge means 16 Erom a closed position 20, shown by the dotted lines, which is parallel to front wall 13 and in which endgate 14 extends across the width of the back of the truck box between side walls 11 and 12, to an open position 21, shown by the full lines, in which endgate 14 is approximately parallel to and closely adjacent to side wall 12. Although both Figures 1 and 2 show the endgate hinged at right hand side wall 12, it is to be understood that the endgate could equally well be hinged at left hand side wall 11.
Figure 3 illustrates further details of the preerred embodiment of the invention, in which endgate 14 comprises side panels 30 and 31 which are fastened along their top edges to rigid member 32, and fastened along their bottom edges to rigid member 33. The fastening of such rigid members to side panels 30 and 31 thus allows endgate 14 to be moved as an integral structure. Upper center panel 34 and lower center panel 35 are not fastened to rigid member 32 or 33~ but are moun-ted by hinges 36 and 37 respectively to side panel 31. Central grain gate 38~ and optionally side grain gates 39 and 40 may also be provided, to facilitate unloading.
Rigid member 32 is preferably a piece oE box tubing which extends substan-tially from -the outside edge of side panel 30 to the outside edge of side panel 31. Rigid member 33 is preferably a fla-t strap of the same leng-th as rigid member 33r There must of course be sufficient clearance between rigid member 33 and the deck of the truck box, in order to allow pivotal movement of the endgate 14.
Those skilled in the art will recognize that other types of rigid members and other fastening techniques may be employed to create a unitary structure.
Stop means 17 is preferably a piece of angle iron extending from the top to the bottom or side wall 11, which protrudes slightly rom -the inside surface of side wall 11 so as to prevent endgate 14 from pivoting outwardly beyond closed position 20. ~atch means 18 is any conventional means selectively permitting or preventing inward pivotal movement of endgate 14~ Of course, other conventional stop means or latch means, or combined stop and latch means, may also be suitable. For example! stop and latch means which may be selectively positioned into a hole or holes in the truck box bed may be provided.
In an alternative embodiment, the endgate comprises two separate endgate structures, rather than being a unitary structure. For example, one o the endgate structures could consist of ~he center panel and one side panel of a conventional endgate, and the other endga-te structure could consist of the other side panel. One endgate structure would be hinged to one side wall, and the other structure would be hinged to the other side wall. Each endgate structure would -then be capable oE being swung inwardly agains-t the side wall to which it is attached. It is recognized that this embodimen-t may not possess all of the advantages of the preferred embodiment.
It will be apparent to -those skilled in the art that numerous modifications of the preferred embodiment may be made without departing from the scope of the present inven-tion, which is defined in the appended claims.

DETAILED l~ESCRIPTION OF THE P~EFERR~D EMBODIrlENI
Figure 1 illustrates a truck box generally designated as 10, having side walls 11 and 12, front wall 13 and endgate structure 14 (here.inaEter "endgate") pivotably mounted on side wall 12 along vertical axis 15, by means of hinge means 16. Stop means 17 and latch means 18 are provided at -the end of side wall :Ll. Endgate 14 is shown in a partially open position.
Figure 2 indicates tha-t endgate 14 may be pivoted inwardly about hinge means 16 Erom a closed position 20, shown by the dotted lines, which is parallel to front wall 13 and in which endgate 14 extends across the width of the back of the truck box between side walls 11 and 12, to an open position 21, shown by the full lines, in which endgate 14 is approximately parallel to and closely adjacent to side wall 12. Although both Figures 1 and 2 show the endgate hinged at right hand side wall 12, it is to be understood that the endgate could equally well be hinged at left hand side wall 11.
Figure 3 illustrates further details of the preerred embodiment of the invention, in which endgate 14 comprises side panels 30 and 31 which are fastened along their top edges to rigid member 32, and fastened along their bottom edges to rigid member 33. The fastening of such rigid members to side panels 30 and 31 thus allows endgate 14 to be moved as an integral structure. Upper center panel 34 and lower center panel 35 are not fastened to rigid member 32 or 33~ but are moun-ted by hinges 36 and 37 respectively to side panel 31. Central grain gate 38~ and optionally side grain gates 39 and 40 may also be provided, to facilitate unloading.
Rigid member 32 is preferably a piece oE box tubing which extends substan-tially from -the outside edge of side panel 30 to the outside edge of side panel 31. Rigid member 33 is preferably a fla-t strap of the same leng-th as rigid member 33r There must of course be sufficient clearance between rigid member 33 and the deck of the truck box, in order to allow pivotal movement of the endgate 14.
Those skilled in the art will recognize that other types of rigid members and other fastening techniques may be employed to create a unitary structure.
Stop means 17 is preferably a piece of angle iron extending from the top to the bottom or side wall 11, which protrudes slightly rom -the inside surface of side wall 11 so as to prevent endgate 14 from pivoting outwardly beyond closed position 20. ~atch means 18 is any conventional means selectively permitting or preventing inward pivotal movement of endgate 14~ Of course, other conventional stop means or latch means, or combined stop and latch means, may also be suitable. For example! stop and latch means which may be selectively positioned into a hole or holes in the truck box bed may be provided.
In an alternative embodiment, the endgate comprises two separate endgate structures, rather than being a unitary structure. For example, one o the endgate structures could consist of ~he center panel and one side panel of a conventional endgate, and the other endga-te structure could consist of the other side panel. One endgate structure would be hinged to one side wall, and the other structure would be hinged to the other side wall. Each endgate structure would -then be capable oE being swung inwardly agains-t the side wall to which it is attached. It is recognized that this embodimen-t may not possess all of the advantages of the preferred embodiment.
It will be apparent to -those skilled in the art that numerous modifications of the preferred embodiment may be made without departing from the scope of the present inven-tion, which is defined in the appended claims.
