DETAILED DESCRIPTION OF THE INVENTION

(4) Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the ladder conversion kit for hauling objects. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used with ladder tree stands for hauling game. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(5) Referring now to FIGS. 1 and 2, there are shown a perspective view of the present invention and a perspective view of the present invention being secured to a ladder tree stand. The present invention is a bracket 11 and wheel 12 that is removably attachable to a ladder tree stand 51 or other similar devices such as ladders or devices that have ladder or ladder-like portions in order to make it more convenient to transport the ladder tree stand 51 and additionally convert the ladder tree stand 51 into a carrying device for supporting objects thereon. The present invention comprises a bracket 11 having a first arm 13 and a second arm 14 connected by a cross member 21 positioned perpendicularly therebetween. The first and second arms 13, 14 are in a spaced relationship and are adapted to accept a ladder rail 53 therethrough. In the depicted embodiment of the present invention, the first and second arms 13, 14 are disposed in a parallel relationship, creating a substantially rectangular, U-shaped bracket 11 adapted to accept a portion of a rectangular ladder rail 53. However, no claim is made as to a specific orientation or positioning of the first and second arms 13, 14 and alternative orientations of the first and second arms 13, 14 may be provided in order to accommodate ladder rails 53 of various shapes and configurations.

(6) The first arm 13 further comprises a channel 15 disposed thereon that is adapted to accept a ladder rung 52 therein. In the depicted embodiment of the present invention, the channel 15 is rectangular in shape; however, no claim is made as to a specific shape for the channel 15 as the channel 15 may be adapted to accept ladder rungs 52 of various cross sectional shapes therein. The bracket 11 further comprises a plurality of apertures 16 disposed on the first and second arms 13, 14. Each aperture 16 disposed on the first arm 13 is aligned with a corresponding aperture 16 disposed on the second arm 14, thereby creating at least one set of aligned pairs of apertures 16 through which a locking pin 17 may be inserted. The locking pins 17 extend between the opposing first and second arms 13, 14, creating a physical barrier preventing the bracket 11 from disengaging from the ladder rung and rail 52, 53 to which it is attached, thereby ensuring that the present invention is securely held in place on the ladder tree stand 51. The locking pins 17 comprises any type of locking pin known in the prior art, such as detent ring pins, clevis fasteners, and positive lock pins, or any other locking mechanism known in the prior art that is adapted to removably secure the bracket 11 to a ladder rail 53.

(7) An alternative embodiment of the present invention comprises a plurality of sets of aligned apertures 16 disposed at positions corresponding to various depths of a ladder rail 53. This allows users to adjust the positioning of the locking pin 17 to accommodate ladder rails 53 of various sizes, ensuring that the present bracket 11 is snugly held against the ladder tree stand 51 regardless of the design of the ladder portion. These aligned sets of apertures 16 may be arranged in parallel sub-sets, as depicted, so that multiple locking pins 17 can be used to secure the present invention in place. Alternatively, the aligned sets of apertures 16 may be arranged in a single set so that a single locking pin 17 may be used to hold the present invention in place. In the depicted embodiment of the present invention, the bracket 11 comprises six aligned sets of apertures 16 arranged in two parallel sub-sets extending along opposite sides of the first and second arms 13, 14; however, no claim is made as to a specific number or arrangement of aligned sets of apertures 16.

(8) The offset between the first and second arms 13, 14 defines a space adapted to enclose a ladder rail 53 therein and the channel 15 disposed on the first arm 13 defines a space adapted to enclose a ladder rung 52 therein. The lateral movement of the present invention is restricted in the side-to-side direction, relative to the longitudinal axis of the ladder 51, by the first and second arms 13, 14 and in the up-and-down direction by the locking pins 17 and the cross member 21 disposed substantially parallel thereto. The longitudinal movement of the present invention is restricted by the channel 15, which encloses a ladder rung 52. As the present invention is locked to both a ladder rail 53 and a ladder rung 52, it is securely held in place to the ladder portion of the ladder tree stand 51 and can cannot slip or fall therefrom in either longitudinal or lateral directions.

(9) The present invention further comprises a wheel 12 extending from said bracket 11. The wheel 12 is rotatably connected to the bracket 11 via any means known in the prior art. The wheel 12 is positioned so that when the bracket 11 is secured to the ladder rail 53 and rung 52, the wheel 12 may freely rotate without obstruction from the ladder portion of the ladder tree stand 51. In the depicted embodiment of the present invention, the wheel 12 extends from the cross member 21 portion of the bracket 11 and is disposed adjacently to the exterior surface of the ladder rails 53 when the present invention is attached to a ladder tree stand 51. In an alternative embodiment of the present invention, the wheel 12 may be attached to the bracket 11 such that the wheel is disposed beneath the ladder tree stand 51 when the present invention is affixed thereto, or in any other orientation that allows for the free and unobstructed rotation of the wheel 12.

(10) The wheel 12 is a conventional wheel as is commonly known in the prior art. In the depicted embodiment of the present invention, the wheel 12 comprises a tire 19 and a plurality of spokes 20 rotatably connected to a hub 18. The hub 18 is attached to the cross member 21 of the bracket 11. It is contemplated that the hub 18 may be attached to the cross member 21 via a fastener or the hub 18 and the cross member 21 may be welded together. In one embodiment of the present invention, the tire 19 is composed of puncture-proof material, such as solid polyurethane. This is an advantageous design because when transporting a ladder tree stand 51 from a hunting location in the wilderness utilizing the present invention, the user may be forced to transport the ladder tree stand 51 over rough terrain.

(11) When attached to a ladder tree stand 51, the present invention provides a removable wheel 12 or set of wheels when used in combination, thereby allowing users to push or pull a ladder or ladder tree stand 51, rather than being forced to carry the ladder or ladder tree stand. Furthermore, when the present invention is affixed to a ladder or ladder tree stand 51, the ladder or ladder tree stand 51 can then be used as a second class lever with a support surface for carrying various objects thereon, allowing individuals to efficiently transport both the ladder tree stand 51 and other objects simultaneously. As the bracket 11 may be freely affixed around any of the ladder rungs 52, the user can adjust the position of the present invention on the ladder tree stand 51 depending upon the weight and size of the load to be transported, the most comfortable position for the user, and the terrain over which the user will be traversing.

(12) The present invention is utilized by sliding a ladder rung 52 of the user's choosing into the channel 15, which additionally causes the first and second arms 13, 14 to slide over an adjacent portion of the ladder rail 53. The user then places the locking pins 17 through the aligned sets of apertures 16 corresponding to the depth of the ladder rail 53, thereby ensuring that the bracket 11 is securely held thereagainst. Once the present invention is secured in place, users may then load other objects onto the upper surface of the ladder tree stand 51 and then simultaneously transport both the ladder tree stand 51 itself and the objects supported thereon. The present invention is usable with conventional ladders, ladder tree stands, and other such devices having ladder or ladder-like components. The present invention is ideally suited for transporting both a ladder tree stand and the user's killed game after the user has been hunting.

(13) Without the present invention, these hunters generally must take multiple separate trips to carry their equipment, ladder tree stand, and game from their hunting location to their vehicle because it would be impossible to carry all of those items due to their bulk. However, the present invention provides a convenient, efficient means for simultaneously transporting all of these items when the hunter is alone or otherwise lacks assistance to carry his or her goods. The present invention is preferably utilized in at least pairs, wherein each of the pair is secured to an opposite ladder rail 53 so that the ladder tree stand 51 and load carried thereon is balanced between each device.

(14) It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(15) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
