Abstract
A snowplow assembly may include a support member, a mount member, and an actuator. The mount member may be operatively connected to a plow blade and pivotally connected to the support member and the mount member may pivot about a substantially vertical axis with respect to the support member. The mount member may include a first stop member for limiting the pivotal motion of the mount member about the substantially vertical axis in a first direction. The actuator may pivot the mount frame about the substantially vertical axis and a first end of the actuator may be operatively connected to the snowplow assembly and a second end may be pivotally connected to the mount member.
Claims19
A snowplow assembly comprising:
- a support member having a first end operatively attached to a vehicle;
- a mount member comprising:
- a plow blade side operatively connected to a plow blade having a snow engaging surface for use in plowing snow;
- a support side pivotally connected to the support member, wherein the mount member pivots about a substantially vertical axis with respect to the support member;
- a first stop member for use in limiting the pivotal motion of the plow blade about the substantially vertical axis in a first direction, the first stop member comprising:
- (1) a first stop plate having a height and a width with a first ratio of height to width between 0.5 and 5, and (2) a C-shaped portion for positioning the first stop member to contact the first side of the support member, wherein the first stop plate operatively contacts a first side of the support member defining a first contact surface, and wherein the first contact surface extends substantially the entire length from a top portion to a bottom portion of the first side of the support member, and wherein the first stop plate extends above a top portion of the C-shaped portion;
- a second stop member for limiting the pivotal motion of the plow blade about the substantially vertical axis in a second direction, the second stop member comprising:
- (1) a second stop plate having a height and a width with a first ratio of height to width between 0.5 and 5, and (2) a C-shaped portion for positioning the first stop member to contact the second side of the support member, wherein the second stop plate operatively contacts a second side of the support member defining a second contact surface, and wherein the second contact surface extends substantially the entire length from a top portion to a bottom portion of the second side of the support member, and wherein the second stop plate extends above a top portion of the C-shaped portion;
- and,
- a first actuator for use in pivoting the plow blade about the substantially vertical axis, wherein a first end of the first actuator is pivotally connected to the support member and a second end of the first actuator is pivotally connected to the mount member, and wherein a second ratio of a first distance between the second end of the actuator and the substantially vertical axis and a second distance between the stop member and the substantially vertical axis is between 1.1 and 2.0.

A snowplow assembly comprising:
- a support member comprising:
- a first member having a first end and a second end, wherein the second end is operatively attached to a vehicle;
- a second member having a first end and a second end, wherein the second end is operatively attached to a vehicle, and wherein the first end of the first member is fixedly attached to the first end of the second member forming an apex portion;
- and
- a cross member having:
- (1) a first end fixedly attached to the first member at a position spaced from the first end of the first member, wherein at least a portion of the cross member is between a first horizontal plane defined by a top portion of the first member and a second horizontal plane defined by a bottom portion of the first member, (2) a second end fixedly attached to the second member at a position spaced from the first end of the second member, wherein at least a portion of the cross member is between a third horizontal plane defined by a top portion of the second member and a fourth horizontal plane defined by a bottom portion of the second member, (3) a forward most surface;
- and, (4) a rearward most surface, wherein the forward most surface is closer to the apex portion than the rearward most surface, and wherein the forward most surface defines a first vertical plane and the rearward most surface defines a second vertical plane;
- a mount member comprising:
- a plow blade side operatively connected to a plow blade having a snow engaging surface for use in plowing snow;
- a support side pivotally connected to the apex portion, wherein the mount member pivots about a substantially vertical axis with respect to the support member;
- a first stop member for limiting the pivotal motion of the mount member about the substantially vertical axis in a first direction, wherein a portion of the first stop member operatively contacts a portion of the support member between the first vertical plane and the second vertical plane, and wherein the first stop member extends above a top portion of the mount member;
- and
- a second stop member for limiting the pivotal motion of the mount member about the substantially vertical axis in a second direction, wherein a portion of the second stop member operatively contacts a portion of the support member between the first vertical plane and the second vertical plane and wherein the second stop member extends above a top portion of the mount member;
- and
- a first actuator for pivoting the mount frame about the substantially vertical axis, wherein a first end of the first actuator is operatively connected to the snowplow assembly and a second end of the first actuator is operatively connected to the mount member.
