Patent CA-2434908-A1 (CA)
Inventor: SCHULTZ LYNN W
IPC: E01H5/06
Filed: 2003-07-10
Abstract: An improved snow plow for use with light and medium duty trucks is disclosed which has blade trip springs which are mounted using brackets located to direct the force of the springs in directions which are orthogonal to the axis upon which the plow blade pivots, thereby increasing the predictability of the tripping forces exerted by the trip springs as well as eliminating lateral trip spring forces which could warp the plow blade. The forces exerted by the trip springs are exerted proximate planes which are orthogonal to the pivot points at which the snow plow blade is mounted to the snow plow blade support structure. Either a single trip spring on either side of the snow plow blade or two trip springs on each side of the snow plow blade may be used, and the size of the trip springs is minimized by ensuring that all of the forces which they exert are directed properly in the requisite directions.
