Mudflap assembly

1. A mudflap assembly comprising:

a hanger for supporting a mudflap, the hanger comprising a horizontal substantially rectangular portion and a substantially cylindrical portion at a first end of said substantially rectangular portion, said substantially cylindrical portion contiguous with said substantially rectangular portion, said substantially cylindrical portion comprising a first protrusion on a top side of said substantially cylindrical portion and a second protrusion on a bottom side of said substantially cylindrical portion;

a bracket having a vertical substantially flat rear portion and a first and second leg contiguous with the substantially flat rear portion, said first leg extending from a first end of the vertical substantially flat rear portion and said second leg extending from a second end of said vertical substantially flat rear portion, said first leg having a first opening and said second leg having a second opening, said substantially cylindrical portion is rotatably coupled to said bracket wherein said substantially cylindrical portion is inserted between said first leg and said second leg and said first protrusion on said top side of said substantially cylindrical portion fits within said first opening of said first leg and said second protrusion on said bottom side of said substantially cylindrical portion fits within said second opening of said second leg, such that upon impact of said hanger with an obstacle, a second end of said hanger rotates around said bracket, radially displacing said hanger from an initial position and as said hanger rotates, said first protrusion and said second protrusion rotate within said first and second openings, respectively,

wherein the first leg comprises a detent, said detent having downwardly sloping sides that terminate at a low point and said hanger has a crevice having downwardly sloping sides that terminate at a low point such that the downwardly sloping sides of said detent slidably move along the downwardly sloping sides of said crevice to displace from the detent from said crevice upon impact of said hanger with an obstacle.

2. The mudflap assembly of claim 1 , wherein the first leg and the second leg of said bracket form a cavity for receiving said substantially cylindrical portion of said hanger.

3. The mudflap assembly of claim 2 wherein said substantially cylindrical portion of said hanger further comprises the crevice on said top side of said substantially cylindrical portion, the crevice for receiving said detent when said substantially cylindrical portion is inserted into said cavity.

4. The mudflap assembly of claim 3 wherein said hanger further comprises a slot for receiving said mudflap.

5. A mudflap assembly comprising

a hanger comprising a first end for supporting a mudflap and a second end comprising a first protrusion on a top surface of said second end and a second protrusion on a bottom surface of said second end, the second end further comprising a first crevice positioned adjacent said first protrusion and a second crevice positioned adjacent said second protrusion;

a bracket for connecting to a vehicle and for rotatably receiving said second end of said hanger, said bracket comprising a first opening and a first detent on a top side of the bracket, said first detent having downwardly sloping sides that terminate at a low point, the first detent adapted for being received by said first crevice when said first protrusion is inserted in said first opening, said first crevice having downwardly sloping sides that terminate at a low point, said bracket further comprising a second opening and a second detent on a bottom side of said bracket, said second detent having upwardly sloping sides that terminate at a high point, said second detent adapted for being received by said second crevice when said second protrusion is inserted in said second opening, said second crevice having upwardly sloping sides that terminate at a high point,

wherein when said first and second detent receive said first and second crevice, respectively, said hanger is maintained in an initial position with respect to said bracket unless said hanger is acted upon by a horizontal force sufficient to displace said first and second detents from said first and second crevices and when said horizontal force is sufficient to displace said detents from said crevices said sloping sides of said detents slidably travel along said sloping sides of said crevices and when said horizontal force is removed, the detents slidably travel along said sloping sides to the initial position.

6. The mudflap assembly of claim 5 wherein said hanger further comprises a slot for receiving said mudflap.

7. A method, comprising the steps of:

supporting a mudflap with a hanger;

inserting a substantially cylindrical first end of said hanger into a bracket such that a protrusion on a top side of the hanger fits within an opening in a top side of said bracket and a detent having downwardly sloping sides that terminate at a low point on said top side of said bracket is received by a crevice adjacent said protrusion on said top side of said hanger, said crevice having downwardly sloping sides that terminate at a low point;

upon impact of said hanger with an obstacle, rotating said hanger thereby radially displacing said mudflap from an initial position such that said protrusion rotates in said opening and said detent slidably escapes said crevice by moving along said downwardly sloping sides of said crevice; and

when said impact is removed, radially replacing the hanger to the initial position wherein said detent slidably moves along said downwardly sloping sides of said crevice and rests within said crevice.

8. The method of claim 7 , further comprising the step of urging said hanger to return to said initial position after said hanger has been acted on by a horizontal force.

9. A mudflap assembly comprising

a hanger for supporting a mudflap, said hanger comprising, at a first end, a protrusion on a top side of said hanger and a crevice on said top side of said hanger positioned adjacent said protrusion, said crevice having downwardly sloping sides that terminate at a low point;

a bracket rotatably coupled to said hanger at said first end of said hanger, said bracket comprising an opening on a top side of said bracket and a detent positioned adjacent said opening, said opening adapted for receiving said protrusion and said detent having downwardly sloping sides that terminate at a low point adapted for being received by said crevice.

10. The mudflap assembly of claim 9 , wherein said top side and a bottom side of said bracket form a cavity for receiving said first end of said hanger.

11. The mudflap assembly of claim 9 wherein said hanger further comprises a slot for receiving a mudflap.
