[0010] For a further understanding of the nature and objects of the present invention, reference should be made to the following detailed description, taken in conjunction with the accompanying drawings, in which like elements are given the same or analogous reference numbers and wherein:

[0011] FIG. 1 is a perspective view of an exemplary embodiment of the trailer alignment backing aid of the present invention showing the target sticker with the peel off backing and the hitch ball attachable aiming tube assembly, the hitch ball attachable aiming tube assembly including the ball attachment tube and the extender tube, the ball attachment tube including the ball insertion flaps, the trailer tongue insertion window, and incremental measuring marks along the length thereof, the extender tube being slidable into the ball attachment tube.

[0012] FIG. 2 is a plan view showing the lower portion of the transparent ball attachment tube with the ball insertion flaps resiliently gripping the ball of a representative ball hitch and the ball of the representative ball hitch extending into the trailer tongue insertion window.

[0013] FIG. 3 is a side plan view showing the hitch ball attachable aiming tube assembly attached to the ball of a representative ball hitch, the trailer tongue of a representative trailer positioned behind the ball of the trailer hitch, and the exemplary target sticker adhesively attached to the bow of a representative boat.

[0014] FIG. 4 is a perspective view of a second exemplary embodiment of the hitch ball attachable aiming tube assembly including the ball attachment tube and the extender tube, the ball attachment tube including the ball insertion flaps, the trailer tongue insertion window, incremental measuring marks along the length thereof, and an extender plate secured to the bottom of the ball attachment tube behind the ball insertion flaps, the trailer tongue insertion window; the extender tube being slidable into the ball attachment tube.

[0015] FIG. 1 shows an exemplary embodiment of the trailer alignment backing aid of the present invention, generally designated by the numeral 10. In this embodiment, backing aid 10 includes a target sticker, generally designated 12; and a hitch ball attachable aiming tube assembly, generally designated 14. Target sticker 12 is of conventional construction, measures three and one-half inches by two and one-half inches (3.5″×2.5″) and includes a front surface 16 having aiming indicia 18 provided thereon and an adhesive covered back surface 20 having a peel off backing cover 22. In this embodiment, aiming indicia 18 is a series of different colored triangles set within each other.

[0016] Hitch ball attachable aiming tube assembly 14 includes a ball attachment tube, generally designated 26; and an extender tube, generally designated 28. Ball attachment tube 26 is of transparent plastic construction and has a one and five-eighths inch internal diameter. Two resilient ball insertion flaps 30a,30bare provided at a lower end thereof and a trailer tongue insertion window 32 is provided just above insertion flaps 30a,30b.In this embodiment flaps 30a,30bare about two and one-half inches in height and insertion window 32 is about two inches in height. With reference to FIG. 2, as discussed herein before, ball insertion flaps 30a,30bare sized and spaced to resiliently grip the ball 36 of a ball hitch, generally designated 38, with sufficient gripping force to maintain hitch ball attachable aiming tube assembly 14 in an upright position during use. With reference to FIG. 3, trailer tongue insertion window 32 is sized such that the tongue 40 of a trailer, generally designated 42, is positionable therein and over ball of trailer hitch 38. Ball attachment tube 26 also includes incremental measuring marks 50 along the length thereof. Each measuring mark 50 includes a numerical indicator in the manner of a ruler to allow a user to measure the height of the trailer tongue 40 (FIG. 3) before beginning the backing procedure.

[0017] With reference back to FIG. 1, in this embodiment, extender tube 28 is slidable into ball attachment tube 26. Providing a slidable extender tube 28 allows the user to adjust the top end of the extender tube 28 to a height that corresponds with the placement of, with reference now to FIG. 3, target sticker 12. In this example, target sticker 12 is attached to the bow of a boat 54. It has been found by the inventor hereof that the target sticker 12 is particularly effective when backing the hitch into connection with the tongue of a travel trailer or other towable vehicle that is not as symmetrical about its center as for instance a boat.

[0018] With reference to FIG. 4, it has also been found effective with novice drivers to provide a ball attachment tube 26athat is identical to ball attachment tube 26 (FIG. 1) except ball attachment tube 26aincludes rigid plastic extender plate 60 that is secured to the bottom of ball attachment tube 26abehind ball insertion flaps 30a,30band trailer tongue insertion window 32. Extender plate 60 has a left portion 62 and a right portion 64 that each extend past the sidewall of ball attachment tube 26ato provide areas for the trailer tongue to strike bending ball attachment tube 26ashould the novice driver miss trailer tongue insertion window 32.

[0019] It can be seen from the preceding description that a trailer alignment backing aid for vehicles has been provided that is attachable to the ball of a trailer hitch and that provides a visual indication to the driver of the vehicle of the location of the ball of the trailer hitch; that includes a measuring mechanism for allowing a driver to verify the height of the tongue of the trailer; and that includes a target sticker and a hitch ball attachable aiming tube assembly; the target sticker having aiming indicia provided on a front surface thereof and an adhesive covered back surface having a peel off backing cover; the hitch ball attachable aiming tube assembly including a ball attachment tube and an extender tube; the ball attachment tube including two ball insertion flaps at a lower end thereof, a trailer tongue insertion window adjacent to the ball insertion flaps, and incremental measuring marks along the length thereof; the two ball insertion flaps being sized and spaced to resiliently grip the ball of a ball hitch and maintain the hitch ball attachable aiming tube assembly in an upright position; the trailer tongue insertion window being sized such that the tongue of a trailer is positionable therein and over the ball of the trailer hitch before the tongue contacts the ball attachment tube; the extender tube being slidable into the ball attachment tube.
