System for attaching an accessory such as a snowplow to a vehicle
View Patent ↗A system for mounting an implement onto a vehicle includes a mounting plate with a first and a second bearing surface, a locator opening and a detent-receiving opening. A mounting fixture is configured to be attached to an accessory such as a snowplow blade. The mounting fixture includes a first hook configured and disposed so as to engage the first bearing surface and a second hook configured and disposed so as to engage the second bearing surface. A locator projection extends from the mounting fixture and is configured to engage and pass through the locator opening. A detent member extends from the mounting fixture and is configured to pass through the detent-receiving opening and releasably engage the plate.
1. A system for mounting an accessory onto a vehicle, the system comprising:
a mounting plate configured to be attached to the underside of the vehicle in a generally horizontal orientation, the mounting plate having a first and a second bearing surface defined thereon;
a locator opening defined through the mounting plate and spaced from the bearing surfaces;
a detent-receiving opening defined through the mounting plate and spaced from the locator opening and the bearing surfaces; and
a mounting fixture configured to be attached to an accessory, the mounting fixture including a first hook configured and disposed so as to engage the first bearing surface and a second hook configured and disposed so as to engage the second bearing surface;
a locator projection extending from the mounting fixture, the locator projection configured to engage and pass through the locator opening; and
a detent member extending from the mounting fixture, the detent member configured to pass through the detent-receiving opening and releasably engage the plate;
wherein the mounting fixture has a mounted position wherein the first hook engages the first bearing surface, the second hook engages the second engaging surface, the locator projection engages the locator opening and the detent member passes through the detent opening and engages the mounting plate.
2. The system of claim 1 , wherein:
the first and second bearing surfaces are defined on a front edge of the plate.
3. The system of claim 1 , wherein:
the locator opening is a first locator opening and the locator projection is a first locator projection;
the mounting plate further having a second locator opening defined therethrough, spaced from the first locator opening; and
the mounting fixture further having a second locator projection extending therefrom, the second locator projection configured to engage and pass through the second locator opening.
4. The system of claim 3 , wherein:
the mounting plate has side edges, the first locator opening being proximate one of the side edges and the second locator opening being proximate the other of the side edges.
5. The system of claim 1 , wherein:
the first and second hooks are fixed to the mounting structure and have rearward facing openings.
6. The system of claim 1 , wherein:
the first and second bearing surfaces are at least partially cylindrical.
7. The system of claim 1 , wherein:
the mounting fixture has a generally planar upper surface and the mounting plate has a generally planar lower surface, the upper surface of the mounting fixture abutting and being parallel to the lower surface of the mounting plate when the mounting fixture is in the mounted position.
8. The system of claim 1 , wherein:
the detent member is a hook;
the system further having a biasing spring urging the hook into engagement with the plate.
9. The system of claim 1 , wherein:
the mounting fixture has a mounting portion that mounts to the mounting plate and further includes a push tube assembly with a rear end pivotally interconnected with the mounting portion and an opposed front end for attachment to the accessory.
10. The system of claim 9 , wherein the push tube assembly has a mid portion with an articulation joint, the articulation joint allowing a portion of the push tube assembly forward of the joint to pivot upwardly with respect to a portion of the push tube assembly rearward of the joint, the push tube assembly further having a spring biasing the articulation joint such that the forward portion is biased downwardly.
11. The system of claim 9 , further comprising:
a release mechanism for releasing the detent member from the plate to detach the mounting fixture from the plate, the release mechanism including a lever mounted to the push tube assembly spaced from the rear end and a linkage interconnecting the lever with the detent member.
12. A system for mounting an accessory onto a vehicle, the system comprising:
a mounting plate configured to be attached to the underside of the motor vehicle in a generally horizontal orientation, the mounting plate having a first and a second bearing surface defined on a front edge thereof;
a mounting fixture configured to be attached to an implement, the mounting fixture including a first hook configured and disposed so as to engage the first bearing surface and a second hook configured and disposed so as to engage the second bearing surface, the mounting fixture having a mounted position wherein the first hook engages the first bearing surface, the second hook engages the second engaging surface;
a locator opening defined through the mounting plate or the mounting fixture and a locator projection extending from the other of the mounting plate or the mounting fixture, the locator projection configured to engage and pass through the locator opening when the mounting fixture is in the mounted position; and
a detent-receiving opening defined through the mounting plate or the mounting fixture and a detent member extending from the other of the mounting plate or the mounting fixture, the detent member configured to pass through the detent-receiving opening and releasably intercormect the mounting fixture and mounting plate in the mounted position.
13. A system for mounting an accessory onto a vehicle, the system comprising:
a mounting plate configured to be attached to the underside of the motor vehicle in a generally horizontal orientation, the mounting plate having a generally planar lower surface with a detent opening defined therethrough;
a mounting fixture configured to be attached to an accessory, the mounting fixture having a mounting portion with a generally planar upper surface, the mounting portion having a mounted position wherein the upper surface of the mounting portion abuts and is parallel to the lower surface of the mounting plate, the mounting fixture having a detent member extending therefrom, the detent member extending through the detent opening and engaging the mounting plate when the mounting portion of the mounting fixture is in the mounted position;
the mounting fixture further including a push tube assembly with a rear end pivotally interconnected with the mounting portion, an opposed front end for attachment to an implement, and a mid portion therebetween;
a release mechanism for releasing the detent member from the plate to detach the mounting fixture from the plate, the release mechanism including a lever mounted to the mid portion of the push tube assembly spaced from the rear end and a linkage interconnecting the lever with the detent member.
14. The system of claim 13 , wherein:
the mid portion of the push tube assembly includes an articulation joint, the articulation joint allowing a portion of the push tube assembly forward of the joint to pivot upwardly with respect to a portion of the push tube assembly rearward of the joint, the push tube assembly further having a spring biasing the articulation joint such that the forward portion is biased downwardly.
