  "abstract": "A convertible snow plow system attachable to frame of a light duty truck, SUV or other suitable vehicle. The blade portion of the plow system is movable between deployed and retracted positions. In the retracted position the blade is positioned in front of the radiator and headlights of the vehicle functioning as a brush guard. To permit air to pass through the plow blade to the radiator, the blade comprises a plurality of movable louvers that can be opened when the plow is in the retracted position.",
  "claims": [
    "1. A convertible plow system for use on a vehicle, the plow system comprising: one or more frame mounting brackets; at least a pair of extension arms, the extension arms being pivotally coupled to the one or more mounting brackets and being movable between at least a deployed extension arm position and a retracted extension arm position, the pair of extension arms extending substantially upwardly in the retracted extension arm position when mounted on the vehicle and the pair of extension arms extending substantially outwardly from the vehicle in the deployed extension arm position when mounted on the vehicle; and a plow blade assembly, the plow blade assembly comprising (i) a plow framework having a concave curvature, a top edge, a bottom edge, and left and right side edges, the plow framework being pivotally attached to a distal end of each extension arm of the pair of extension arms, (ii) a plurality of louvers, each louver of the plurality of lovers being pivotally mounted to the plow framework and collectively having at least an open orientation and a closed orientation; wherein the plow blade assembly is moveable between a deployed plow blade position and a retracted plow blade position when mounted on the vehicle with the bottom edge of the plow frame work being adjacent to a ground surface and the concave curvature facing away from the vehicle in the deployed plow blade position and with the plow frame work being in front of a grill of the vehicle and the concave curvature facing towards the vehicle in the retracted plow blade position.",
    "2. The convertible plow system of claim 1, further comprising at least one extension arm actuator, the at least one extension arm actuator being coupled to a frame mounting bracket of the one or more frame mounting brackets at a first end and to an extension arm of the pair of extension arms at a second end, wherein the at least one extension arm actuator is adapted for at least partially moving the plow frame between the deployed and retracted positions.",
    "3. The convertible plow system of claim 2, wherein the at least one extension arm actuator includes first and second extension arm actuators.",
    "4. The convertible plow system of claim 2, wherein the at least one extension arm actuator comprises a linear actuator.",
    "5. The convertible plow system of claim 1, further comprising at least one plow frame actuator, the at least one plow frame actuator being coupled to an extension arm of the pair of extension arms at first end and to the plow frame at a second end, wherein the at least one plow frame actuator is adapted for at least partially moving the plow system between the deployed and retracted positions.",
    "6. The convertible plow system of claim 2, further comprising at least one plow frame actuator, the at least one plow frame actuator being coupled to an extension arm of the pair of extension arms at first end and to the plow frame at a second end, wherein the at least one plow frame actuator is adapted for at least partially moving the plow system between the deployed and retracted positions.",
    "7. The convertible plow system of claim 1, wherein each of the pair of extension arms comprise a pair nested of telescoping tubes and the convertible plow system further includes a pair of tilt actuators, each tilt actuator coupled to the nested telescoping tubes of a respective extension arm wherein when the plow system is mounted on the truck, the tilt actuators are adapted to change the angle of the plow frame relative to the truck.",
    "8. The convertible plow system of claim 6, wherein each of the pair of extension arms comprise a pair nested of telescoping tubes and the convertible plow system further includes a pair of tilt actuators, each tilt actuator coupled to the nested telescoping tubes of a respective extension arm wherein when the plow system is mounted on the truck, the tilt actuators are adapted to change the angle of the plow blade assembly relative to the truck.",
    "9. The convertible plow system of claim 1, further including a light bar assembly.",
    "10. The convertible plow system of claim 8, further including a light bar assembly.",
    "11. A motor vehicle including the convertible plow system of claim 1.",
    "12. A motor vehicle including the convertible plow system of claim 8.",
    "13. The convertible plow system of claim 1, wherein each of the plurality of louvers is coupled to the plow frame proximate a leading edge thereof.",
    "14. The convertible plow system of claim 1, further comprising louver actuators, the louver actuators adapted for moving the plurality of louvers between the open and closed orientations.",
    "15. The convertible plow system of claim 1, wherein the plurality of louvers are adapted for manual movement between the open and closed orientations.",
    "16. The convertible plow system of claim 15, wherein the plow system is adapted for manual movement between the deployed and retracted positions.",
    "17. The convertible plow system of claim 1, wherein the one or more frame mounting brackets comprise a pair of frame mounting brackets.",
    "18. The convertible plow system of claim 1, wherein the plurality of louvers overlap to form a plow blade face when in the closed orientation and wherein the plurality of louvers are substantially parallel and spaced apart in the open orientation to permit the free flow of air therethrough.",
    "19. A method of configuring the convertible plow system of claim 1 for use as a plow on a motor vehicle, the method comprising: providing the motor vehicle having the convertible plow system attached thereto; moving the at least a pair of extension arms from a retracted extension arm position to a deployed extension arm position; moving the plow blade assembly from a retracted plow blade position to a deployed plow blade position; and moving the plurality of louvers from an open orientation to a closed orientation.",
    "20. A method of configuring the convertible plow system of claim 1 for use as a plow on a motor vehicle, the method comprising: providing the motor vehicle having the convertible plow system attached thereto; moving the at least a pair of extension arms from a retracted extension arm position to a deployed extension arm position; moving the plow blade assembly from a retracted plow blade position to a deployed plow blade position; moving the plurality of louvers from an open orientation to a closed orientation; and actuating one or both of the pair of tilt actuators to tilt the plow blade assembly to one of the right and the left."

  "description_excerpt": "Snow plow attachments for vehicles and particularly light duty trucks are well know; however, the plows must typically be removed when not in use as they otherwise impede the practical use of the vehicle. Removable snow plow attachments also require a non-trivial amount of time and effort to attach and detach the plow making their use less convenient for spur of the moment use, such as might be desired in light to moderate snow fall situations. Plow attachments must be stored potentially taking up a significant amount of floor space when not in use. Additionally, plow attachments have little usefulness when an occasion arises warranting use but the attachment is not in the same location as the truck to which it is to be attached.\n\nRetractable plow attachments have been proposed, but suffer from one or more significant drawbacks. For instance, U.S. Pat. No. 8,528,237 describes a plow that can be retracted underneath the associated vehicle; however, when in the retracted position, the effective ground clearance of the vehicle is severely reduced.\n\nFIG. 1A is a side view of the convertible plow system in the brush guard or retracted position attached to a pickup truck according to an embodiment of the present invention.\n\nFIG. 1B is a cross sectional view of the convertible plow system taken across line 1 B- 1 B of FIG. 1A according to an embodiment of the present invention.\n\nFIG. 2 is a side view of the convertible plow system in the brush guard or deployed position attached to a pickup truck according to an embodiment of the present invention.",
