The disclosure relates to trailer hitch devices and more particularly pertains to a new trailer hitch device for facilitating the hitching of a trailer to a trailer hitch.
The prior art relates to trailer hitch devices which incorporate a means of coupling a trailer to the hitch receiver of an automobile alternative to a traditional ball hitch connection in the hopes of making the process of hitching easier. Several of these devices use mechanisms comprising an inserting member being received into a receiving member. Of these devices, at least two examples make use of a winch system to urge the inserting member into the receiving member and guide the inserting member accordingly. Another pair of devices, the ones disclosed in U.S. Pat. Nos. 4,844,497 and 10,252,588 B2, use receiving members that flare open in an effort to make adjustments to minor misalignments in coupling the two components. However, both of these devices require connecting a different mechanism to the hitch receiver of the automobile. What is missing from the prior art is a mechanism which uses an inserting member that is received into a receiving member, the receiving member having a flared opening to correct misalignments, and which is adaptable to a hitch ball to facilitate efficient alternating between different trailers. Also disclosed in the present invention which is missing in the prior art is a visual alignment means to facilitate the alignment of the inserting and receiving members.
An embodiment of the disclosure meets the needs presented above by generally comprising a hollow tube with a hitch ball receiver and a hitch ball latch which are configured to cooperatively secure the tube to a hitch ball. A flared member at the end of the tube flares from the tube to an opening. A trailer tongue member is configured for attaching to a trailer frame, an insertion member extends from said trailer tongue member and is insertable into said tube through said opening. When the insertion member is positioned in a locking position, a locking pin is inserted through holes in the tube and the insertion member, thereby securing the insertion member to the tube.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
A plate 32 is coupled to the bottom side 22 of the tube 18, and the plate 32 has a bottom side 34 away from the tube 18. The plate 32 extends between the pair of lateral sides 28 of the tube 18 and is configured for extending from the distal end 26 of the tube 18 to a hitch plate 36 when the hitch ball receiver 12 receives the hitch ball 16. A flared member 38 is coupled to the distal end 26 of the tube 18 and extends from a proximal end of the flared member 38 relative to the tube 18 to a distal end 42 of the flared member 38 relative to the tube 18. The flared member 38 flares from the proximal end 40 of the flared member 38 to the distal end 42 of the flared member 38. The flared member 38 is hollow and has an opening at the distal end 42 of the flared member 38. The flared member 38 extends from the bottom side 34 of the plate 32 to the top side 20 of the tube 18 and between the lateral sides 28 of the tube 18 at the proximal end 40 of the flared member 38. The flared member 38 has a circular cross section at the distal end 42 of the flared member 38.
A trailer tongue member 44 is configured for coupling to a trailer frame 46 by means of a plurality of fasteners 48 extending through the trailer tongue member 44 and the trailer frame 46. The trailer tongue member 44 has a proximal end 50 relative to the trailer frame 46 and a distal end 52 relative to the trailer frame 46. The trailer tongue member 44 also has a top surface 54 extending from the proximal end 50 of the trailer tongue member 44 to the distal end 52 of the trailer tongue member 44 and a bottom surface 56 opposite the top surface 54 of the trailer tongue member 44. An alignment member 58 extends from the top surface 54 of the trailer tongue member 44 adjacent the proximal end 50 of the trailer tongue member 44. The alignment member 58 has a first surface 60 aligning with the proximal end 50 of the trailer tongue member 44 and a second surface 62, which is a concave curved surface extending from the first surface 60 to the top surface 54 of the trailer tongue member 44. The second surface 62 tangentially meets the top surface 54 of the trailer tongue member 44.
An insertion member 64 extends from the distal end 52 of the trailer tongue member 44 adjacent the top surface 54 of the trailer tongue member 44, along a central longitudinal axis of the insertion member 64. The insertion member 64 has a square cross section and is insertable into the tube 18. The insertion member 64 has a proximal section 66 relative to the trailer tongue member 44, a distal section 68 relative to the trailer tongue member 44, and a middle section 70 extending between the proximal section 66 and the distal section 68. The proximal section 66 tapers from the trailer tongue member 44 to the middle section 70, the middle section 70 is complementary in shape to the tube 18, and the distal section 68 tapers from the middle section 70 to a distal end 72 of the insertion member 64 relative to the trailer tongue member 44. A bumper 74 protrudes from the trailer tongue member 44 adjacent the bottom surface 56 of the trailer tongue member 44, tapering away from the trailer tongue member 44. The bumper 74 is constructed of a resiliently compressible material.
A tube hole 84 perpendicular to the central longitudinal axis of the tube 18 extends through the top side 20 of the tube 18 to the bottom side 22 of the tube 18. A first indicator 78 of a pair of indicators is aligned with the central longitudinal axis of the tube 18 and is coupled to the flared member 38 and the top side 20 of the tube 18. The first indicator 78 extends from the distal end 42 of the flared member 38 to the tube hole 84. A second indicator 80 of the pair of indicators is aligned with the central longitudinal axis of the insertion member 64 and extends along the top surface 54 of the trailer tongue member 44 and the second surface 62 of the alignment member 58. The pair of indicators is constructed of a reflective material and visually indicates a relative angle between the tube 18 and the insertion member 64.
A plate hole 80 extends through the plate 32 and aligns with the tube hole 84. An insertion member hole 82 extends through the middle section 70 of the insertion member 64. The insertion member hole 82 aligns with the tube hole 84 when the insertion member 64 is in a locking position 86. A locking pin 88 is insertable in an insertion position 100 through the tube hole 84, the insertion member hole 82, and the plate hole when the insertion member 64 is in the locking position 86, thereby securing the insertion member 64 to the tube 18.
The locking pin 88 has a pin section 90, a ring section 92, and a collar section 94. The pin section 90 has a first end 96 and a second end 98. The ring section 92 extends laterally through the pin section 90 proximate the first end 96 of the pin section 90. The collar section 94 is circumferentially coupled to the pin section 90 proximate the ring section 92 and engages the tube 18 when the locking pin 88 is in the insertion position 100. The locking pin 88 defines a pin hole 102 extending laterally through the pin section 90 proximate the second end 98 of the pin section 90. A hairpin cotter pin 104 is positionable such that the hairpin cotter pin 104 inserts through the pin hole 102 and clips to the locking pin 88 when the locking pin 88 is in the insertion position 100, thereby securing the locking pin 88 to the tube 18. A line 106 couples the ring section 92 of the locking pin 88 to the tube 18.
In use, with the hitch receiver and the hitch latch securely clamped to the hitch ball 16 and the trailer tongue member 44 being coupled to the trailer frame 46, a vehicle to which the hitch ball 16 is coupled reverses to receive the insertion member 64 into the tube 18. The flared member 38 facilitates minor adjustments in positioning the tube 18 relative to the insertion member 64. If the vehicle has a backup camera, the driver of the vehicle may also visually determine the relative angle between the tube 18 and the insertion member 64 and correct course accordingly. Once the insertion member 64 is in the locking position 86, the locking pin 88 is inserted into said tube hole 84, the insertion member hole 82, and the plate hole 80 to secure the insertion member 64 to the tube 18. Then the hairpin cotter pin 104 is inserted into the pin hole 102 and clipped to the locking pin 88 to secure the locking pin 88 to the tube 18.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, 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 an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure 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 disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
