Self-centering device for quick hooking and release of farm tools provided with a hydraulic hoister

A self-centering assembly for quick hooking and release of farm tools, comprising:

• a substantially triangular configured female element having two side section bars which diverge out from an apex region and are fixedly joined together by an intermediate member, and each of said side section bars having a C-shaped open wing cross-section which is defined by an outer wall with two wing walls extending out at an obtuse angle with respect to an interior surface of said outer wall, and said female element including means for attaching said female element with one of a tractor and a farm tool;
• a substantially triangular configured male element having two male side sections which diverge out from an apex location and are fixedly joined together by a joining member extending between said male side sections, each of said male side sections featuring an exterior surface configuration which corresponds with an interior surface of a respective one of said C-shaped, open wing cross-sectioned side section bars such that said male element is slideably received, in a self-centering fashion, by said female element, and said male element including means for securing said male element with an opposite one of said tractor and farm tool than that which said female element is attached;
• and
• a latch mechanism for coupling said female and male elements so as to prevent separation of said male and female element.

A self-centering assembly for quick hooking and release of farm tools;

• comprising:
• a male element having two male side sections which diverge out from an apex location and are fixedly joined together by a joining member extending between said male side sections, and said male element including means for securing said male element to one of a tractor and a farm tool;
• a female element having two side section bars which diverge out from a common apex region and are rigidly fixed together by an intermediate member, each of said section bars having a first, forward end in said apex region and a second rearward end, said rearward ends being spread further apart than said forward ends with respect to a common plane, and said section bars of said female element having a generally C-shaped configuration for sliding reception and weight support of respective ones of said male side sections, which sliding reception includes insertion of said male element through said open insertion space along said common plane, said female element further including means for attaching said female element to an opposite one of the tractor and the farm tool than that which said male element is secured, and said self-centering assembly further comprising a latch mechanism, which, when in locking position, includes a component that extends forward of the forward ends at the apex region of said female element and latches said male and female elements to prevent relative sliding therebetween.
