Abstract
The invention is a trailer-type snowplow assembly. The assembly includes one pivot mechanism that allows the plow blade to be raised or lowered. The assembly further includes a free pivot assembly that allows the blade to freely pivot in a transverse direction in response to directional changes of the tow vehicle or uneven snow impact along its length. Also disclosed is a multi-piece plow blade that has removable end portions that allow a user to elongate or shorten the effective length of the plow blade.
Claims14
A snowplow assembly adapted for removable securement to a vehicle, said assembly comprising;
- a support fixture;
- a plow blade adapted for plowing snow when moved in a predetermined direction;
- a first attachment means connected to the support fixture and adapted for attachment to an end of a vehicle;
- and
- a second attachment means connected to the support fixture, and wherein said second attachment means is also connected to the plow blade and includes a pivot assembly that allows the plow blade to freely pivot in a horizontal plane at all times and wherein the pivot assembly of the second attachment means is in the form of at least one elongated member that may freely slide within a complementary slot.
A snowplow assembly adapted for removable securement to the rear of a vehicle, said snow plow assembly comprising:
- a central member having a front portion, a rear portion and a pivot means connecting said front and rear portions whereby said pivot means enables said rear portion to move in a vertical direction relative to the front portion;
- a connecting means located at one end of the central member and adapted for securement to a receiving means located on the rear of a vehicle;
- a winch means attached to said central member in a manner wherein operation of said winch means causes the rear portion of the central member to pivot relative to the front portion;
- and
- a plow blade adapted for plowing snow and attached by a pivot means to an extreme rear end portion of the rear portion of the central member, said pivot means allowing the plow blade to automatically pivot in response to unequal forces applied along the length of the plow blade.
