Abstract

An implement coupling apparatus configured to facilitate coupling and de-coupling of an implement such as but not limited to a bucket from the operator's cab of the machinery. The invention includes a first side plate member and a second side plate member each having a first end a second end. Lug apertures and lugs are present on each side member being configured to engage hub notches of an implement. A wedge bar member is operably disposed between the first side plate member and second side plate member and is movable between a first and second position. The wedge bar member includes opposing ends that protrude beyond the first side plate member and second side plate member. A spring assembly having two compression springs is operably coupled to the wedge bar member. A control cylinder is operably coupled to the wedge bar member to provide movement thereof.

Claims (16)

1 . An implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery wherein the implement coupling apparatus comprises:

a body, said body having a first side plate member and a second side plate member located on opposing sides of the body, said first side plate member and said second side plate member being parallel and operably coupled, said first side plate member having a first end and a second end, said second side plate member having a first end and a second end, said first side plate member having a first lug aperture and a second lug aperture distally located on said first side plate member, said second side plate member having a first lug aperture and a second lug aperture being axially aligned with the first lug aperture and the second lug aperture formed in said first side plate member, said body having a rear wall, said rear wall extending intermediate said first side plate member and said second side plate member being perpendicular thereto, said first side plate member having a wedge bar aperture, said second side plate member having a wedge bar aperture being axially aligned with said wedge bar aperture of said first side plate member,

a wedge bar member, said wedge bar member being movably disposed within said body intermediate said first side plate member and said second side plate member, said wedge bar member having a first end and a second end, said first end of said wedge bar member extending outward beyond said first side plate member, said second end of said wedge bar member extending outward beyond said second side plate member, said wedge bar member movable between a first position and a second position;

a spring assembly, said spring assembly having at least one spring, said at least one spring operably coupled intermediate said rear wall of said body and said wedge bar member;

a control cylinder, said control cylinder disposed within said body, said control cylinder having a piston operably engaged with said wedge bar member, said control cylinder operable to move said wedge bar member to said first position; and

a lock assembly, said lock assembly being operably coupled to said wedge bar member, said lock assembly having a pin member, said pin member of said lock assembly configured to move in an upwards-downwards motion between a first position and a second position, said lock assembly configured to retain said wedge bar member in said second position, wherein said wedge bar member includes a center section intermediate said first end and said second end of said wedge bar member, said center section having formed therein a lock assembly aperture, said lock assembly further comprising a housing, said housing having a portion configured to be journaled into said lock assembly aperture, said lock assembly being operably coupled to said center section of said wedge bar member.

2 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 1 , and further including a controller, said controller being operably coupled to said control cylinder, said controller configured to provide operation of said control cylinder.

3 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 2 , wherein said first end of said wedge bar member protrudes outward from said wedge bar aperture of said first side plate member.

4 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 3 , wherein said second end of said wedge bar member protrudes outward from said wedge bar aperture of said second side plate member.

5 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 4 , wherein said first end and said second end of said wedge bar member have an upper surface that is angular in orientation.

6 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 5 , wherein said body further includes a lower cover member, said lower cover member further having an aperture formed therein.

7 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 6 , wherein said pin member of said lock assembly is configured to be journaled into said aperture of said lower cover member in said second position of said pin member.

8 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 7 , wherein said first end and said second end of said wedge bar member are configured to operably and mateably couple with coupling notches of the implement.

9 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 8 , wherein said spring assembly includes a first spring member and a second spring member, said first spring member and said second spring member being intermediate said rear wall of said body and said wedge bar member.

10 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 9 , wherein said first lug aperture and said second lug aperture of said first side plate member include lugging operably coupled therewith.

11 . The implement coupling apparatus configured to facilitate coupling and de-coupling of an implement to machinery as recited in claim 10 , wherein said first lug aperture and said second lug aperture of said second side plate member include lugging operably coupled therewith.
