ATV loader/carrier system

Abstract

A fixed frame has upper, lower, and lateral bars in a vertical frame. A movable frame has inner, outer, and side bars in a horizontal plane. The movable frame includes forward, rearward, and side panels. Hinges pivotably couple the side panels to the side bars allowing movement between a horizontal lowered orientation for loading and unloading cargo and a horizontal raised orientation for transporting cargo. Motion imparting mechanisms couple the movable frame with respect to the fixed frame for moving the movable frame between the lowered and raised orientations.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(11) With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved ATV loader/carrier system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

(12) The present invention, the ATV loader/carrier system 10 is comprised of a plurality of components. Such components in their broadest context include a fixed frame, movable frame, and a motion imparting mechanism. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

(13) An ATV 14 is provided. The ATV includes a body 16. The body has a front 18. The front is provided forwardly. The body has a rear 20. The rear is provided rearwardly. The body has four wheels 22. The wheels are adapted to be positioned at ground level during operation and use. The preferred embodiment of the present invention as illustrated includes an ATV, an all terrain vehicle. It should be understood, however, that the invention is also capable of use on a wide variety of other vehicles including a UTV, a utilitarian vehicle, such as a golf cart, a mini-pick up truck, and like vehicles.

(14) A fixed frame 26 is provided. The fixed frame is attached to the rear of the ATV. The fixed frame has an upper bar 28. The fixed frame has a parallel lower bar 30. The fixed frame has parallel lateral bars 32 forming the sides. In this manner the fixed frame is formed into a rectangular configuration in a vertical plane.

(15) Provided next is a movable frame 36. The movable frame is operatively coupled to the fixed frame. The movable frame has an inner bar 38. The movable frame has a parallel outer bar 40. The movable frame has parallel side bars 42. In this manner a movable floor with a rectangular configuration is formed in a horizontal plane. The movable frame includes a forward panel 44. The forward panel is provided in a rectangular configuration. The forward panel is attached to and extends upwardly from the inner bar. The movable frame includes a rearward panel 46. The rearward panel is in a generally rectangular configuration. The rearward panel is attached to and extends upwardly from outer bar. The movable frame includes two similarly configured side panels 48. The side panels are in a rectangular configuration. Hinges 50 are provided. The hinges pivotably couple the side panels to the side bars. In this manner movement between a horizontal orientation and a vertical orientation is allowed. The horizontal orientation allows for loading and unloading cargo. The vertical orientation allows for transporting cargo. Screen material 52 is provided. The screen material fills out the floor and the rear panel and the side panels.

(16) It should be understood a wide variety of hinges may be readily utilized in the system of the present invention. Further, the hinge points, the axes of rotation, may be repositioned on different systems as required by the geometry of the particular system.

(17) A brace bar 54 is provided. The brace bar is attached to the side bars of the movable frame beneath the floor and its screen material. Locks 56 are provided. Each lock is laterally slidable with respect to each side panel. In this manner each side panel is retained in a vertical orientation. A cable 58 is provided. In this manner the downward movement of each side panel to a horizontal orientation is limited. Instead of a cable, a cord or other equivalent component could be readily utilized.

(18) A motion imparting assembly 62 is provided next. The motion imparting assembly couples the movable frame with respect to the fixed frame. The motion imparting assembly includes upper links 64. The upper links have inner ends. The inner ends are pivotably attached to the lateral bars adjacent to the upper bar of the fixed frame. The upper links have outer ends. The outer ends are pivotably attached to the upper bar of the forward panel. The motion imparting assembly includes lower links 66. The lower links have inner ends. The inner ends are pivotably attached to the lateral bars adjacent to the lower bar of the fixed frame. The lower links have outer ends. The outer ends are pivotably coupled to the brace bar of the floor of the movable frame. The upper links and the lower links are curved in the disclosed preferred embodiment as illustrated. The upper links and the lower links have a center of curvature above the system when the movable frame is in the lower orientation. The upper links and the lower links have a center of curvature forwardly of the system when the movable frame is in the raised orientation. The upper and lower links are adapted to take other shapes as a function of the particular application.

(19) Further provided is a winch assembly 70. The winch assembly has a pivotable pulley 72. The pivotable pulley is coupled to the inner bar. The winch assembly includes a dual pulley 74. The dual pulley is rotatably attached to the upper bar of the fixed frame. A rotatable drum 75 is provided. The rotatable drum is attached to the fixed frame in proximity to the rear of the ATV. The winch assembly includes a cable 76. The cable has a fixed end 78. The fixed end is attached to the lower bar of the fixed frame by way of a tension spring. The cable has a movable end 80. The movable end is attached to the rotatable drum.

(20) Provided last a motion imparting device illustrated as a motor 84. The motor is attached to the drum. In this manner rotation of the drum in a winding motion is initiated. Also in this manner the movable frame and lift cargo is raised. At least a portion of the movable frame and cargo are above the ATV. Further in this manner stability is increased. The motor is adapted to initiate rotation of the drum in an unwinding motion. In this manner the movable frame is lowered. Also in this manner the floor is positioned at ground level. Further in this manner when the side panels are lowered cargo may be easily dragged onto the floor for transporting purposes. The motor is operable to raise and lower the movable frame by hard wire controls and/or through a remote control mechanism. It should be understood that a wide variety of motion imparting devices such as a gear drive, hydraulic mechanisms, pneumatic mechanisms, and the like, could be readily utilized as a function of the particular application.

(21) The most stable configuration is to have the center of gravity as low as possible and as forward as possible, preferably in front of the rear wheels. The objective in the design is to end up with the bottom of the basket approximately at the same height as the rear cargo rack for ground clearance on uneven terrain. For stability, the center of gravity should be as far forward as possible. The present configuration provides for a good combination of stability and ground clearance.

(22) As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

(23) 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.

(24) 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.
