Definitions

  • the present invention relates to a pivoting snowplow.
  • Snowplows are used to remove snow and ice from outdoor surfaces such as streets, sidewalks, and driveways. They are either mountable on or integrated into a vehicle and typically include a frame and a blade. Their frames often include multiple adjustment means to raise, lower and angle the blade, and suspension means such as springs or hydraulic cylinders allow the blade to articulate when necessary. While some snowplows include basic pivoting systems such as ball joints and rubber cushions to allow the blade to maintain its horizontal position, there is a need for a more advanced leveling system that can respond to inconsistent surfaces and improve the snow plow’s performance on surfaces of varying heights such as streets and sidewalks.
  • US10119233 discloses a plow assembly for a vehicle.
  • the plow assembly includes a mounting structure configured to mount at a vehicle, a support structure and an accessory or plow.
  • the support structure includes a vehicle end and an attaching end, with the vehicle end attached to the mounting structure via a cushioning assembly.
  • the accessory or plow is pivotally attached at the attaching end of the support structure and is pivotable about a generally vertical axis.
  • the cushioning assembly includes (i) a first element attached at the vehicle end of the support structure, (ii) a second element attached at the mounting structure, and (iii) a plurality of resilient elements disposed between the first element and the second element.

  • Figure 3 is a rear perspective view of a pivoting snowplow in accordance with an additional illustrative embodiment of the present invention.
  • Figures 4A and 4B are rear perspective views of the pivoting snowplow of Figure 3 in a tilted position and a neutral position, respectively.
  • FIG. 1A and 1B there is shown a typical prior art snowplow 2’ that includes a frame 4’ and a blade 6’ and is mountable to a vehicle (not shown).
  • Snowplow 2’ includes a pair of hydraulic cylinders 8’ for adjusting the positioning of the blade 6’ and a pair of shock absorbers 10’ providing the snowplow 2’ with its own suspension system independent of the vehicle’s.
  • a pivot system 12’ including a ball joint 14’ and a rubber cushion 16’ connects the underside of the frame 4’ to the blade 6’ and allows the blade 6’ to pivot about a horizontal axis X’ running transversely across the snowplow 2, albeit with a restricted range of motion.
  • pivot system 12’ allows the blade 6’ to respond to any inconsistencies in the surface on which it is travelling, there is no way for an operator to actively control the angle of the blade 6’ with respect to horizontal axis X’.
  • snowplow 2 includes a frame 4 and a blade 6 and is mountable to a vehicle (not shown) via vehicle mount 18.
  • snowplow 2 includes a pair of hydraulic cylinders 8 for adjusting the positioning of the blade 6 and a pair of shock absorbers 10 providing the snowplow 2 with its own suspension independent of the vehicle.
  • the hydraulic cylinders 8 may extend perpendicularly about a horizontal axis X running transversely across the snowplow 2.
  • snowplow 2 further includes a pivot system 12 including a fixed arm 20 linking the frame 4 to the blade 6 via a first bracket 22 operatively connected to the frame 4 and a second bracket 24 operatively connected to the blade 6.
  • the fixed arm 20 forms an acute angle with respect to said horizontal axis X to provide a pivoting range of motion to the blade 6.
  • Pivot system 12 further includes a pair of rubber springs 26 at a distal end of fixed arm 20 and positioned on either side of the second bracket 24, allowing the blade 6 to pivot about horizontal axis X with reference to the frame 4, between a neutral position and a tilted position.
  • the improved range of motion of snowplow 2 afforded by the pivot system 12 allows the blade 6 to assume a variety of different positions. As shown in Figure 2A, the default or neutral position of blade 6 is horizontal relative to the horizontal axis X.
  • the pivot system 12 would allow the blade 6 to pivot relative to the horizontal axis X by a tilted angle A and by compressing one of the rubber springs 26, as shown in Figure 2B where an object (not shown) has been put under the blade 6, on one side, to simulate the different “X-axis situation”.
  • Figure 2B shows the blade 6 pivoting to the right side when viewed from the vehicle
  • the installation of two rubber springs 26 ensures that the blade 6 may pivot in the opposite direction, illustratively to the left when viewed from the vehicle, if the operation gives the opposite situation.
  • the compressed rubber spring 26 will exert a force against the fixed arm 20 to revert the blade 6 back to its default or neutral position.

  • snowplow 2 includes a pair of hydraulic cylinders 8 for adjusting the positioning of the blade 6 and a pair of shock absorbers 10 providing the snowplow 2 with its own suspension independent of the vehicle.
  • snowplow 2 further includes a pivot system 12 that includes a hydraulic arm 30 (rather than a fixed arm) linking the frame 4 to the blade 6 via a first bracket 22 operatively connected to the frame 4 and a second bracket 24 operatively connected to the blade 6.
  • the hydraulic arm 30 forms an acute angle with respect to said horizontal axis X to provide a pivoting range of motion to the blade 6.
  • Pivot system 12 further includes a pair of rubber springs 26 at a distal end of hydraulic arm 30 and positioned on either side of the second bracket 24, allowing the blade 6 to pivot about horizontal axis X by a pivot angle A with reference to the frame 4.
  • Hydraulic arm 30 includes a pair of fluid supplies 32 for actuating the hydraulic arm 30 and pivoting the blade 6 about the horizontal axis X.
  • fluid is simultaneously injected into one of the fluid supplies 32 and removed from the other fluid supply 32, depending on the desired actuation direction.
  • the snowplow 2 according to the embodiment shown in Figure 3 allows for both actuatable pivoting of the blade 6 via the hydraulic arm 30 and pivoting of the blade 6 in response to road inconsistencies.
  • Figures 4A and 4B the snowplow 2 of Figure 3 is shown in various positions.
  • the hydraulic arm 30 can be used to pivot the blade 6 relative to the horizontal axis X, illustratively to the left as viewed from the vehicle.
  • the hydraulic arm 30 will act as did the fixed arm 20 in the embodiment shown in Figures 2A and 2B and one rubber springs 26 (or the other) will compress, if ever needed, leaving the blade 6 in a horizontal position relative to the horizontal axis X of the ground all the time.
  • a snowplow 2 can be configured to include a pivot system 12 whereby a fixed arm 20 and a hydraulic arm 30 are interchangeable.
  • a bolt 34 may be unscrewed to release the fixed arm 20 and replace it with the hydraulic arm 30, or vice-versa.

Abstract

L'invention concerne un chasse-neige pouvant être monté pivotant sur un véhicule. Ledit chasse-neige comprend : un cadre, une lame couplée au cadre, et un système de pivot comprenant un bras fixe ou hydraulique reliant le cadre à la lame. Le système de pivot comprend une paire de ressorts au niveau d'une extrémité distale du bras fixe ou hydraulique. Le système de pivot est configuré pour permettre à la lame de pivoter d'une position neutre à une position inclinée en référence à un axe horizontal s'étendant transversalement à travers le chasse-neige par compression de l'un des ressorts sur la lame se déplaçant sur une surface avec un angle différent par rapport au véhicule. Le système de pivot est conçu pour ramener la lame de la position inclinée à la position neutre par l'allongement de l'un des ressorts lorsque la lame cesse de se déplacer sur ladite surface. Le bras fixe ou hydraulique forme un angle aigu par rapport à l'axe horizontal.
