Description
- This invention relates to snow removal equipment and, more particularly, to a snowplow assembly of lightweight construction.
- Passenger vehicles have been used for sometime as a means for plowing snow by utilizing snowplow assemblies which are detachably mounted to the passenger vehicle. The passenger vehicles of choice for such plowing have included full size pickups and sport utility vehicles (“SUV's”.)
- Efforts are underway to utilize smaller passenger vehicles for plowing snow. For example, it is desirable to be able to utilize a lightweight pickup as the vehicle for plowing snow with the detachably mountable snowplow assembly. However, conventional detachable snowplow assemblies, built for full size pickups and/or SUV's, can subject such a lightweight pickup to excessive loads due to the weight of the snowplow assembly.
- Accordingly, it is desirable to redesign the conventional passenger vehicle mountable snowplow assembly in an effort to reduce its weight for use on lighter weight vehicles, for example lightweight pickups.
- In accordance with the principles of the present invention, a snowplow assembly comprises a lift frame and A-frame operably pivotally connected together, an actuator operably connected between the lift frame and A-frame for effecting relative pivotal movement between the lift frame and A-frame and a plow blade including a blade frame, the blade frame including a tube of circular cross section, the tube operably pivotally connected to the A-frame.
- The lift frame and A-frame can be adapted to be connected to a vehicle mount frame as a unit. The tube of the blade frame can be pivotally received by a quadrant, the quadrant operably connected to the A-frame. The snowplow assembly can further include a resilient element operable between the blade frame and A-frame normally biasing a lower edge of the plow blade forwardly; the pivotal connection of the plow blade to the A-frame in combination with the resilient element provides a trip function of the plow blade. The resilient element can be non-metallic, for elastomeric. The plow blade can also be non-metallic, for example a composite. The tube can extend substantially the width of the plow blade. The lift frame can include a pair of extensions extending away from the plow blade, and can be adapted to be received by a vehicle mount frame. The snowplow assembly can further include a pair of support stands removably secured to the lift frame. The tube can include a pair of stops which cooperate with a pair of urethane cushions on the quadrant to limit pivoting movement of the plow blade.
- In another aspect, a snowplow assembly comprises a lift frame and an A-frame operably pivotally connected together, an actuator operably connected between the lift frame and A-frame for effecting relative pivotal movement between the lift frame and the A-frame, a plow blade operably pivotally connected to the A-frame, and a non-metallic resilient endless loop operably connected between the plow blade and A-frame; the pivotal connection of the plow blade to the A-frame in combination with the resilient loop provides a trip function of the plow blade.
- In yet another aspect, a snowplow assembly comprises an A-frame and a plow blade including a tube of circular cross section, the tube operably pivotally connected to the A-frame.
- In still another aspect, a snowplow assembly comprises an A-frame, a plow blade operably pivotally connected to the A-frame, and a non-metallic resilient endless loop operably connected between the plow blade and the A-frame; the pivotal connection of the plow blade to the A-frame in combination with the resilient loop provides a trip function of the plow blade.
- In a further aspect, a snowplow assembly comprises an A-frame, a plow blade including a tube of circular cross section, the tube operably pivotally connected to the A-frame, and a non-metallic resilient endless loop operably connected between the plow blade and A-frame; the pivotal connection of the plow blade to the A-frame in combination with the resilient loop provides a trip function of the plow blade.
