Abstract

An attachment system for attaching an implement mounting assembly to a vehicle. The attachment system includes a vehicle attachment component that is fastenable to a front portion of the frame of the vehicle, and a frame attachment component that is removably attachable to the vehicle attachment component on one end via a securing axis, and pivotably attachable to the implement assembly on another end about a pivoting axis. When fastened to the vehicle, the vehicle attachment component is located upward from the underside of the frame. When the frame attachment component is attached to the vehicle attachment component, the securing axis is located upward from the underside portion of the frame, and the pivoting axis is located downward therefrom.

First claim

The invention claimed is:

1. A mount assembly for mounting a work implement assembly to a vehicle having an undercarriage, a horizontal plane being defined by a lowermost point of the undercarriage when the vehicle is on a horizontal flat ground surface, the work implement assembly including a work implement, a frame and a work-implement-assembly connector supported by the frame, the mount assembly comprising:
a vehicle-mount structure fastenable to a portion of the vehicle, the vehicle-mount structure including a vehicle-mount-structure connector, the vehicle-mount structure being configured such that when the vehicle-mount structure is fastened to the vehicle and the vehicle is on the horizontal flat ground surface, the vehicle-mount structure is located entirely above the horizontal plane;
a work-implement-assembly-mount structure pivotably connectable to the work-implement-assembly connector about a first horizontal pivot axis, the work-implement-assembly-mount structure including a work-implement-assembly-mount-structure connector structured to be releasably connectable to the vehicle-mount-structure connector for mounting the work implement assembly to the vehicle, the work-implement-assembly mount structure being configured such that when
the vehicle-mount structure is fastened to the vehicle and the vehicle is on the horizontal flat ground surface, and
the work-implement-assembly-mount-structure connector is connected to the vehicle-mount-structure connector,

the first horizontal pivot axis is located below the horizontal plane.

2. The mount assembly of claim 1 , wherein the work-implement-assembly mount structure is configured such that when
the vehicle-mount structure is fastened to the vehicle and the vehicle is on the horizontal flat ground surface, and
the work-implement-assembly-mount-structure connector is connected to the vehicle-mount-structure connector,

the first horizontal pivot axis is located below the horizontal plane by a distance of between 2 to 5 inches.

3. The mount assembly of claim 1 , wherein, when the vehicle-mount structure is fastened to the vehicle, the vehicle-mount structure is located rearward of a forwardmost point of the vehicle.

4. The mount assembly of claim 3 , wherein the vehicle-mount structure further includes a vehicle-mount-structure anterior surface facing forwardly and downwardly when the vehicle-mount structure is fastened to the vehicle and the vehicle is on the horizontal flat ground surface.

5. The mount assembly of claim 4 , wherein the work-implement-mount structure further includes a work-implement-mount-structure anterior surface shaped to register with the vehicle-mount-structure anterior surface when the work-implement-mount-structure connector is connected to the vehicle-mount-structure connector.

6. The mount assembly of claim 5 , wherein the work-implement-mount-structure connector is pivotably connectable to the vehicle-mount-structure connector about a vehicle-mount-structure-connector axis for pivoting the work-implement-mount structure about the vehicle-mount-structure-connector axis, and when the work-implement-mount-structure anterior surface registers with the vehicle-mount-structure anterior surface, the work-implement-mount-structure anterior surface registers with the vehicle-mount-structure anterior surface to prevent pivoting of the work-implement-mount structure about the vehicle-mount-structure-connector axis.

7. The mount assembly of claim 1 , wherein the vehicle-mount structure further includes a vehicle-mount-structure posterior surface extending rearwardly when the vehicle-mount structure is fastened to the vehicle and the vehicle is on the horizontal flat ground surface.

8. The mount assembly of claim 7 , wherein the work-implement-mount structure further includes a work-implement-mount-structure posterior surface shaped to register with the vehicle-mount-structure posterior surface when the work-implement-mount-structure connector is connected to the vehicle-mount-structure connector.

9. The mount assembly of claim 8 , wherein the work-implement-mount-structure connector is pivotably connectable to the vehicle-mount-structure connector about a vehicle-mount-structure-connector axis for pivoting the work-implement-mount structure about the vehicle-mount-structure-connector axis, and when the work-implement-mount-structure posterior surface registers with the vehicle-mount-structure posterior surface, the work-implement-mount-structure posterior surface registers with the vehicle-mount-structure posterior surface to prevent pivoting of the work-implement-mount structure about the vehicle-mount-structure-connector axis.

10. The mount assembly of claim 1 , wherein the work-implement-mount structure further includes a linkage, the work-implement-mount structure pivotably connectable to the work-implement-assembly connector about the first horizontal pivot axis via the linkage.

11. The mount assembly of claim 10 whereby when the vehicle is on a horizontal ground surface, the vehicle-mount structure is fastened to the vehicle and the vehicle-mount-structure connector is connected to the work-implement-mount-structure connector:
the work-implement-mount-structure connector is located above the horizontal plane, and;
the linkage extends from above the horizontal plane to below thereof.

12. The mount assembly of claim 10 , wherein the linkage is pivotably connected to the work-implement-mount-structure connector for pivoting about a second horizontal pivot axis.

13. The mount assembly of claim 12 , wherein when the vehicle is on the horizontal ground surface, the vehicle-mount structure is fastened to the vehicle and the vehicle-mount-structure connector is connected to the work-implement-mount-structure connector, the second horizontal pivot axis located higher than the first horizontal pivot axis.

14. A mount assembly for mounting a work implement assembly to a vehicle; the work implement assembly including a frame supporting a work implement, a work-implement-assembly connector and a winch connector; the work-implement-assembly connector and the winch connector supported by the frame; the vehicle including an undercarriage and a winch operatively connectable to the winch connector for pulling the frame toward the vehicle; a horizontal plane being defined by a lowermost point of the undercarriage when the vehicle is on a horizontal flat ground surface; the mount assembly comprising:
a vehicle-mount structure fastenable to the vehicle, the vehicle-mount structure including a vehicle-mount-structure connector; and
a work-implement-mount structure connectable to the work-implement-assembly connector, the work-implement-mount structure including a work-implement-mount-structure connector releasably connectable to the vehicle-mount-structure connector for mounting the work implement assembly to the vehicle when the work-implement-mount-structure connector is in longitudinal, lateral and vertical alignment with the vehicle-mount-structure connector;

when
the vehicle-mount-structure is fastened to the vehicle,
the work-implement-mount structure is connected to the work-implement-assembly connector,
the winch is connected to the winch connector, and
the winch pulls the work-implement-assembly frame towards the vehicle,

a guided portion of the work-implement-mount structure is cooperable with a guiding portion of the vehicle-mount structure to orient the work-implement-mount-structure connector relative to the vehicle-mount-structure connector to be in longitudinal, lateral and vertical alignment therewith.
