Abstract
A snowblade assembly is disclosed which is mechanically mounted to a motor vehicle in substantially the same manner as the original bumper and which has a snowblade which is moveable between a forwardly extending pointed position and a generally planar position. The snowblade is attached to the vehicle by a four bar linkage assembly having tubular telescoping portions therein and which is partially contained within box housing members. A pair of springs are also used to normally bias the snowblade in a perpendicular position relative to the traversed ground.
Claims13
A snowblade assembly for attaching a snowblade to a motor vehicle, said motor vehicle traveling over a plurality of ground objects wherein, said snowblade engages said ground objects, said snowblade assembly comprising:
- channel means moveable between a planar and a pointed position for mounting said snowblade;
- four bar linkage means pivotally connected to said channel means for horizontally extending said channel means from said vehicle and for causing said channel means to pivotally rotate upon said engagement of said ground objects by said snowblade;
- winch means, connected to said four bar linkage means, for raising and lowering said channel means;
- and
- containment means, connected to said vehicle, for partially containing said four bar linkage means and for limiting said raising and lowering of said channel means by said winch means.
A snowblade assembly for attachment to a motor vehicle having a bumper connected thereto and traversing a plurality of ground objects, said snowblade assembly comprising:
- snowblade means for defining a snowblade, wherein said snowblade engages said ground objects and is normally positioned perpendicular to said ground, said snowblade being moveable between a planar and a pointed position;
- channel means, connected to said snowblade means, moveable between a planar and a pointed position for mechanically supporting said snowblade means;
- four bar linkage means, pivotally connected to said channel means for extendably positioning said channel means from said vehicle and for causing said channel means to pivotally tilt upon said engagement of said ground objects by said snowblade and for allowing said snowblade means to be raised and lowered while remaining perpendicular to said ground;
- containment means connected to said vehicle in substantially the same manner as said bumper, for containing said four bar linkage means and for limiting said raising and lowering of said snowblade means;
- and
- spring biasing means connected to said containment means for biasing said snowblade means to said normal perpendicular position after said tilt of said channel means.
A snowblade assembly for attachment to a motor vehicle having a bumper connected thereto and traversing a plurality of ground objects, said snowblade assembly comprising:
- snowblade means for defining a snowblade, wherein said snowblade engages said plurality of ground objects and is normally perpendicular to said ground, said snowblade being moveable between a planar and a pointed position;
- channel means connected to said snowblade means and moveable between a planar and a pointed position for mechanically supporting said snowblade means;
- four bar linkage means pivotally connected to said channel means for extendably positioning said channel means from said vehicle and for causing said channel means to move between said planar and said pointed position, said four bar linkage means defining an axis of swing upon said movement between said planar and said pointed position and for causing said channel means to pivotally rotate upon said engagement of said plurality of ground objects by said snowblade means and for allowing said snowblade means to be raised while remaining perpendicular to said ground;
- winch means connected to said four bar linkage means for raising said snowblade means;
- and
- containment means connected to said vehicle in substantially the same manner as said bumper for pivotally mounting said four bar linkage means, said mounting being in close proximity to said vehicle, and for limiting said raising of said snowblade means;
- spring biasing means connected to said containment means and having a longitudinal axis of symmetry being in alignment with said axis of swing;
- winch support means connected to said containment means for supporting said winch.
