[0031] With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new vehicle hitch and trailer tongue alignment system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
[0032] As best illustrated in FIGS. 1 through 4, the invention includes a vehicle hitch and trailer tongue alignment system 10 for mounting on a vehicle 4 and a trailer 2 to be hitched to the vehicle 4. The vehicle 4 suitably includes a hitch ball support 12 extending rearwardly from the vehicle 4 and a hitch ball 14 mounted on an upper surface of the hitch ball support 12. The trailer 2 suitably includes a tongue 18 with hitch ball receiver 20 mounted at a forward end of the tongue 18. The hitch ball receiver 20 includes a hitch ball cavity 64 for receiving the hitch ball 14.
[0033] The system of the invention includes a projecting apparatus 24 for mounting on the hitch ball support 12 of the vehicle 4. The projecting apparatus 24 includes a first support mount 26 for mounting to the hitch ball support 12. The first support mount 26 comprises a clamp 28 for clamping on the hitch ball support 12 at a location adjacent to and forward of the hitch ball 14. The clamp 28 includes a base 25 and a pair of depending arms 27 mounted to the base 25. The depending arms 27 are substantially parallel. A space formed between the depending arms for receiving a portion of the support 12. One of the depending arms 27 includes a threaded rod 30 passing through a threaded hole 31 in the arm 27. The threaded rod 30 includes an end which is advanceable into the space between the arms 27 for pressing against a hitch ball support 12 received between the arms 27 and forcing the support against the other of the arms 27. A support post 32 is mounted to the support mount 26 for extending in a substantially vertical orientation when the support mount 26 is mounted on a hitch ball support 12.
[0034] A connector member 34 is mounted on the support post 32, and may have a degree of slidability on the post 32 for permitting vertical adjustment of the distance between the connector member 34 and the hitch ball 14. The connector member 34 includes a first recess for receiving the support post 32, and preferably the connector member 34 is pivotable on the support post for permitting directional adjustment. A top member 38 is fixedly mounted to the connector member 34, and has second recess for receiving and mounting a light source 36 for shining a relatively focused linear beam of light. A lumen in communication with the second recess may extend through the top member 38 for permitting the light source 36 to be shifted in the lumen to vertically align an end of the light source with the hitch ball (see FIG. 4). The top member 38 (and the light source mounted thereon) extends substantially perpendicular to the support post 32 for projecting a light beam that is substantially horizontal when the support post is mounted on a hitch ball support.
[0035] A target apparatus 40 is provided for mounting on the tongue 18 of the trailer 2 adjacent to the hitch ball receiver 20 of the tongue. The target apparatus 40 includes a second support mount 42 for mounting to the tongue 18 of the trailer 4. The second support mount 42 comprises a saddle 44 for embracing on the hitch ball receiver 20. The saddle 44 comprises a bridge portion 46 and a locating portion 48. The bridge portion 46 includes a lateral segment 58 for resting on a top surface of the hitch ball receiver 20 in an orientation transverse to the longitudinal axis of the tongue 18, and a pair of depending segments depending from the lateral segment. The locating portion 48 includes a front segment 52 and a pair of side segments 50 extending in a spaced parallel relationship from the front segment 52.
[0036] A pole 54 is mounted to the second support mount 42, and is also mounted to the bridge portion 46 of the saddle 44 of the second support mount 42. The pole 54 extends in a substantially vertical orientation when the second support mount 42 is mounted on a hitch ball receiver 20. The pole 54 includes an upper end and a lower end, with the lower end being mounted to a central location on the lateral segment 58 of the bridge portion 46. The pole 54 includes an upper portion 60 and a lower portion 62, and the upper portion 60 is removably couplable to the lower portion 62 of the pole. The depending segments 50 of the bridge portion 46 are connected to the side segments 50 of the locating portion 48 in a manner positioning the lower end 62 of the pole 54 above the hitch ball cavity 64 of the hitch ball receiver 20. A pole coupler 66 is provided for removable coupling the upper portion 60 of the pole 54 to the lower portion 62 of the pole 54.
[0037] A target 68 is provided for being illuminated by light from the light source of the projecting apparatus 24. The target 68 is designed for mounting on the pole 54. The target 68 may be slidably moveable along the length of the pole 54. The target 68 is elongate and includes a longitudinal axis that is oriented parallel to the longitudinal axis of the pole 54. The target 68 comprises a plate and includes a pair of spaced mounts 70 for receiving portions of the pole. The mounts 68 may be mounted on a front face of the plate of the target 68, such that the pole is located in front of the target toward the projecting apparatus. The spaced mounts 70 may provide sufficient frictional mounting with the post, or may have other suitable means for resisting unintentional slippage of the target along the pole. In one preferred embodiment, separate frictionally slidable members 69 (such as, for example, formed out of an elastomeric material) that may be forcibly slid along the pole (See FIG. 2). One of these members 69 may be positioned on either side of the spaced mounts, for selectively trapping the mounts therebetween.
[0038] Significantly, the target may be of a relatively darker color, and the pole of a lighter color, such that the pole represents the axis of the hitch ball cavity and signifies proper alignment when the light beam from the projecting apparatus shines on the pole. The darker target surface allows the user to see the projection of the light beam when it is just off of the axis of the pole, for assisting in finer adjustments of the vehicle to put the hitch ball on target with the hitch ball cavity. Also, the location of the spaced mounts may permit the user to determine whether the height of the tongue of the trailer is raised sufficiently high off of the ground to accept the hitch ball. For example, the spaced mounts may be positioned at opposite ends of the preferred range of vertical tongue heights (relative to the distance the light beam is separated from the hitch ball) for indicating not only the lateral alignment of the hitch ball with the tongue, but also the acceptable vertical alignment of the hitch ball with the hitch ball cavity.
[0039] In use, the vehicle hitch and trailer tongue alignment system assists a driver in properly aligning a hitch to a trailer without the need for another person to guide the driver. The connector member 34 may be pivoted on the support post 32 to align the top member 38 with a longitudinal axis of the hitch ball support 12 for projecting light rearwardly from the vehicle 4 toward the targeting apparatus 40 on the trailer 2. The vertical position of the may also be adjusted.
[0040] As to a further discussion of 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.
[0041] 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.
[0042] 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.
