Abstract

There is provided a sweeping blade assembly configured to be attached to a plow blade of a vehicle for sweeping debris on a ground surface. The sweeping blade assembly comprises: a blade support securable to the vehicle, a sweeping blade device, and a blade tilting control assembly. The sweeping blade device comprises: a blade main portion mounted to the blade support and tiltable about a pivoting axis. The blade tilting control assembly comprises a protruding abutment protruding from one of the blade supports and the blade main portion and an abutment receiving aperture defined in the other one of the blade support and the blade main portion. The abutment receiving aperture is delimited by an inner peripheral wall. The protruding abutment is engageable in the abutment receiving aperture and displaceable with respect to one another upon tilting of blade main portion about the pivoting axis with the inner peripheral wall of the abutment receiving aperture limiting the tilting of blade main portion. There is also provided a sweeping blade device and a snow plow comprising the sweeping blade assembly.

         8 . The sweeping blade assembly of  claim 1 , wherein the blade tilting control assembly is a single blade tilting control assembly located on one lateral side of the pivoting axis. 
     
     
         9 . The sweeping blade assembly of  claim 3 , wherein the blade support comprises a vehicle mounting portion located rearwardly of the blade main portion when assembled together and the protruding abutment protrudes forwardly from a front face of the vehicle mounting portion. 
     
     
         10 . The sweeping blade assembly of  claim 1 , wherein a perimeter of the abutment receiving aperture delimited by the inner peripheral wall is greater than a perimeter of the protruding abutment. 
     
     
         11 . The sweeping blade assembly of  claim 1 , wherein the blade support comprises a sweeping blade mounting portion located forwardly of the blade main portion when assembled together and the abutment receiving aperture is concealed behind the sweeping blade mounting portion. 
     
     
         12 . The sweeping blade assembly of  claim 1 , wherein a center of the protruding abutment is located in an upper half section of the blade main portion and the protruding abutment is centrally located inside the abutment receiving aperture. 
     
     
         13 . The sweeping blade assembly of  claim 1 , wherein a center of the protruding abutment and the pivoting axis are substantially at a same height on the blade main portion. 
     
     
         14 . A snow plow comprising: a snow plow blade and the sweeping blade assembly of  claim 1  mounted in a lower portion of the snow plow blade. 
     
     
         15 . A sweeping blade device comprising:
 a blade main portion having a front face, a rear face, a single bushing hole, and at least one of:
 a protruding abutment protruding from at least one of the front face and the rear face; and 
 an abutment receiving aperture opened on at least one of the front face and the rear face; and 
   a single bushing assembly including a resilient bushing contained in the single bushing hole and defining a blade-support mounting aperture.
