DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION AND BEST MODE

A loading apparatus according to a preferred embodiment of the invention is illustrated in FIGS. 1-10, and shown generally at reference numeral 10. As shown in FIG. 1, the apparatus 10 generally comprises a hitch attachment 12 connected to a loading ramp 60. The hitch attachment 12 is comprised of a substantially L-shaped lower member 20, an elongate intermediate member 30, an elongate upper member 40 and an elongate support member 50.

As shown in FIGS. 1 and 2, the L-shaped lower member 20 is comprised of a first elongate section 21 extending horizontally, and a second elongate section 22 extending upwardly at approximately a ninety degree angle from the first section. The horizontal section 21 of the lower member 20 is shaped and sized to fit into and engage a receiving hitch 102 of a pick-up truck 100, as shown in FIG. 2. A horizontally oriented tubular section 23 is formed at the top of the second section 22, as shown in FIG. 2. Two holes are formed in the tubular section 23 to receive fastening members such as bolts 25.

As shown in FIGS. 2 and 3, the elongate intermediate member 30 is positioned through the tubular section 23, and extends horizontally. A plurality of holes 35 are formed in the intermediate member 30 in a line along the length of the intermediate member 30. The intermediate member 30 is positioned within the tubular section 23 such that two of the holes 35 in the intermediate member 30 are aligned with the two holes in the tubular section 23. Bolts 25 are positioned through the two holes in the tubular section 23 and the two aligned holes 35 of the intermediate member 30. A vertically oriented tubular section 33 is formed at the distal end of the intermediate member 30. Two holes are formed in the tubular section 33 to receive fastening members such as bolts 35.

As shown in FIGS. 2-4, the elongate upper member 40 extends vertically through tubular section 33. A plurality of holes 45 are formed in the upper member 40 in a line along the length of the upper member 40. The upper member 40 is positioned within the tubular section 33 such that two of the holes 45 in the upper member 40 are aligned with the two holes in the tubular section 33. Bolts 25 are positioned through the two holes in the tubular section 33 and the two aligned holes 45 of the upper member 45.

As shown in FIG. 2-4, the elongate support member 50 is attached to the top of the upper member 40 and extends horizontally. Four tubular sections 53 are attached on the underside of the support member, as shown in FIG. 2. As shown in FIG. 3, a support arm 54 extends upwardly from the support member 50. An opening 55 is formed at the top of the support arm 54, and a stop member 56 can be positioned through the opening 55, as shown in FIG. 3.

As shown in FIGS. 4-6, the loading ramp 60 comprises a front section 62 proximate the hitch attachment 12, and a rear section 72 distal to the hitch attachment 12 and moveably attached to the front section 62. The front section 62 includes a front bar 64 proximate the hitch attachment 12, and the rear section 72 includes a rear bar 74 distal to the hitch attachment 12. The front section 62 and the rear section 72 are joined by a plurality of hinges 68. As such, the loading ramp 60 is moveable from an expanded position in which the front and rear sections 62, 72 are positioned at an incline, as shown in FIGS. 4-6, to a contracted position in which the front and rear sections 62, 72 reside in a substantially vertical orientation, as shown in FIGS. 7-9.

The hinges 68 are constructed to prevent the front and rear sections 62, 72 from extending all the way to a complete co-planar configuration when in the fully expanded position. Preferably, the hinges 68 are constructed to angle the front and rear sections 62, 72 at about fifteen degrees, such that the front section 62 extends at a less steep incline than the rear section 72 when in the fully expanded position, as shown in FIG. 4.

As shown in FIG. 3, four attachment members 66 extend outwardly from the front bar 64. Each of the attachment members 66 is adjacent to one of the tubular sections 53 of the support member 50. An elongate fastening member such as a bolt can be positioned through the attachment members 66 of the loading ramp 60 and into the tubular sections 53 of the support member 50. As such, the loading ramp 60 is pivotably attached to the support member 50, and the loading ramp 60 can pivot about the bolts.

When in the expanded position, the rear bar 74 contacts the ground surface “G”, and the front bar 64 is proximate the tail gate 104 of the pick-up truck when the tail gate 104 is in the fully lowered position. The loading ramp 60 extends from the ground “G” to proximate the lowered tail gate 104 of the pick-up truck 100. As shown in FIG. 4, the front section 62 of the loading ramp 60 is elevated at a slight angle, preferably about fifteen degrees, in relation to the rear section 72. As such, the front section 62 is closer to being level with the horizontal plane of the tailgate 104 than the rear section 72. A vehicle to be transported such as an all terrain vehicle (ATV) 110 can be driven up the loading ramp and into the bed 106 of the pick-up truck, as shown in FIG. 5. The slight angle of the loading ramp 60 at the joining of the front and rear sections 62, 72 reduces the incline of the loading ramp 60 proximate the pick-up truck tailgate 104, as shown in FIG. 4.

After the ATV 110 has been loaded on the pick-up truck 100, the loading ramp 60 can be moved into the contracted position, as shown in FIGS. 7-9, for easy transport. As shown in FIG. 9, the stop member 56 can be inserted through the opening 55 of the support arm 54, and is positioned adjacent the front section 62 of the loading ramp 60, between the front section 62 and rear section 72. As such, the stop member 56 prevents loading ramp from moving back towards the expanded position during transport.

The horizontal length and vertical height of the hitch attachment 12 are adjustable. Preferably, the horizontal length and vertical height are adjusted such that the support member 50 resides in the same horizontal plane as the pick-up tailgate 104 when the tailgate 104 is in the fully lowered position, as shown in FIG. 4. As shown in FIGS. 10-11, the total horizontal length of the hitch attachment 12 can be decreased by removing the bolts 25 from the holes 35a, 35b in the intermediate member, sliding the intermediate member 30 forward (toward the pick-up truck 100), and repositioning the bolts 25 in holes 35d, 35e proximate to the upper member 40, as shown in FIG. 11. The horizontal length can be increased by removing the bolts 25, sliding the intermediate member 30 rearward (away from the pick-up truck 100), and replacing the bolts 25 in holes 3535a, 35b distal the upper member 40, as shown in FIG. 11.

As shown in FIGS. 12-13, the vertical height of the hitch attachment 12 can be decreased, by removing bolts 25 from the holes 45c, 45d in the upper member 40, sliding the upper member downwardly, and repositioning the bolts 25 in holes 45a, 45b proximate the top of the upper member, shown in FIG. 13. As shown in FIGS. 13-14, the vertical height of the hitch attachment 12 can be increased by removing the bolts 35 from the holes 45a, 45b, sliding the upper member 40 upwardly, and repositioning the bolts 35 in holes 45d, 45e proximate the bottom of the upper member 40, as shown in FIG. 14.

Such adjustment allows for the loading apparatus 10 to be used with pick-up trucks and pick-up tailgates of varying size and design. For example, the vertical height of the hitch attachment 12 can be increased so that the loading ramp 60 can reach a pick-up tailgate that sits relatively high up. Also, the horizontal length of the hitch attachment 12 can be increased to accommodate a relatively longer pick-up tailgate.

The hitch attachment 12 can be made of 1.5 inch steel tubing, or other suitable material. The loading ramp 60 can be made of 1.25 inch aluminum tubing, or other suitable material. The loading ramp 60 is preferably seventy-four inches long and fifty inches wide.

A loading apparatus and method of using same are described above. Various changes can be made to the invention without departing from its scope. The above description of the preferred embodiments and best mode of the invention are provided for the purpose of illustration only and not limitation—the invention being defined by the claims and equivalents thereof.
