The disclosure relates to hitch device and more particularly pertains to a new hitch device for preventing a pin from being lifted inadvertently resulting in undesired disengagement of the hitch connection.
The prior art relates to hitch device.
An embodiment of the disclosure meets the needs presented above by generally comprising a hitch frame including a guide plate. A hitch pin is slidably coupled to the hitch frame. An index collar has a notch. The hitch pin is slidable to fully clear a hitch space in the hitch frame only when the notch is aligned with and receives the guide plate. A biasing spring extends between the index collar and the hitch frame wherein the biasing spring urges the index collar away from the guide plate.
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 hitch pin 26 is slidably coupled to the hitch frame 12. A top 28 of the hitch pin 26 extends up through the top plate 14 of the hitch frame 12 and a bottom 30 of the hitch pin 26 extends downwardly from the bottom plate 16 of the hitch frame 12. An index collar 32 is coupled to the hitch pin 26 and positioned between the medial plate 20 and the top plate 14. The index collar 32 has a vertical notch 34 selectively alignable with the guide plate 24. The hitch pin 26 is liftable vertically when the notch 34 is aligned with the guide plate 24.
A biasing spring 36 extends between the top plate 14 and the index collar 32. The hitch pin 26 extends through the biasing spring 36 such that the biasing spring 36 urges the index collar 32 towards the medial plate 20. The index collar 32 has a radially sloped surface 38 extending partially around the index collar 32. A post 40 is coupled to the hitch frame 12 extending upwardly from the medial plate 20. The post 40 is aligned with the radially sloped surface 38 such that contact between the post 40 and the radially sloped surface 38 rotates the index collar 32 as the index collar 32 is urged downwardly by the biasing spring 36 extending between the top plate 14 and the index collar 32. The index collar 32 is fully urged by the biasing spring 36 towards the medial plate 20 to define an unlifted position wherein the notch 34 in the index collar 32 is urged to be offset from vertical alignment with the guide plate 24. Thus, the hitch pin 26 can only be disengaged by a combination of rotation and vertical lifting inhibiting unintended disengagement of the hitch device 10. A handle 42 is coupled to the top end 28 of the hitch pin 26 to facilitate grasping, lifting, and rotating the hitch pin 26.
In use, the handle 42 is grasped to lift the hitch pin 26 and rotate the index collar 32 to align the notch 34 with the guide plate 24. When aligned with the guide plate 24, the notch 34 can receive the guide plate 24 allowing the hitch pin 26 to be further lifted such that the hitch space 22 is cleared by the hitch pin 26. An implement to be engaged by the hitch pin 26 can be inserted into the hitch space 22 and the hitch pin 26 released to be biased downwardly engaging the implement. Further, the post 40 abuts the radially sloped surface 38 to rotate the index collar 32 such that the notch 34 is offset from being vertically aligned with the guide plate 24.
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.
I hereby claim the benefit under 35 U.S.C. Section 119(e) of United States Provisional application 62/739,532 filed Oct. 1, 2018.
