US 12,398,522 B2 · Selectable-width push plow

Abstract

A selectable-width push plow for removing snow or other material. The push plow is configurable in any one of several pre-defined blade-width blade configurations without requiring special tools or great dexterity to adjust, while also allowing for compact storage of the device. The push plow includes a plow blade having a first panel and a second panel pivotably interconnected to the first panel. The second panel is pivotable between a retracted position in which the bottom edges of the first and second panel extend transversely to one another, and an extended position in which the bottom edges of the first and second panel extend in a common direction. The push-plow further includes an adjustable-length handle extend substantially vertically the plow blade and a glide adjacent the bottom of each panel to promote gliding of push plow over concrete, macadam or another rough or uneven surface.

Dependent claims

A push plow comprising:

a plow blade, the plow blade comprising:
a first panel having top and bottom edges, and side edges extending between the top and bottom edges;
a second panel having respective top and bottom edges, and respective side edges extending between its top and bottom edges, the second panel being pivotably interconnected to the first panel to pivot about an axis extending transversely to a front surface of the second panel, the second panel being pivotable about the transversely-extending axis between a retracted position in which the bottom edges of the first and second panel extend transversely to one another and a major portion of the second panel overlies the first panel, and an extended position in which the bottom edges of the first and second panel extend in a common direction and the major portion of the second panel does not overlie the first panel;
and
a handle mounted to the first panel, the handle extending substantially vertically from the first panel when the first panel is in a substantially vertical position.

a first panel having top and bottom edges, and side edges extending between the top and bottom edges;
a second panel having respective top and bottom edges, and respective side edges extending between its top and bottom edges;
a third panel having respective top and bottom edges, and respective side edges extending between its top and bottom edges;
a first pivot joint interconnecting the first and second panels proximally to an intersection of the side and bottom edges of the first and second panels so that the second panel is pivotable about an axis normal to a plane of at least a portion of the first panel between a retracted position in which a majority of the second panel overlies the first panel and the bottom edges of the first and second panel extend transversely to one another, and an extended position in which a majority of the second panel does not overlie the first panel and the bottom edges of the first and second panel extend in a common direction;
a second pivot joint interconnecting the first and third panels proximally to an intersection of the side and bottom edges of the first and third panels so that the third panel is pivotable about an axis normal to a plane of at least a portion of the first panel between a retracted position in which a majority of the third panel overlies the first panel and the bottom edges of the first and third panel extend transversely to one another, and an extended position in which a majority of the third panel does not overly the first panel and the bottom edges of the first and third panel extend in a common direction;
and
a handle mounted to the first panel, the handle extending substantially vertically from the first panel when the first panel is in a substantially vertical position.
