专利汇可以提供Hand operated wheeled v-blade snowplow专利检索，专利查询，专利分析的服务。并且A snowplow particularly adapted to be manually propelled includes a wheel-mounted scraper blade arranged to direct snow laterally. The blade has relatively rigid sides with rear portions being curled outwardly at the upper rear end to provide a concavely curved moldboard, a front apex together with a resilient bottom lip portion arranged relative to the plane of the wheels to reduce blade drag and provide a clean scraping action. A shaft connected transversely between the sides of the blade serves as lateral blade support structure and in addition supports both a pivotal handle and a trailing alignment wheel. The handle is cable-connected to the blade and alignment wheel in such a way that the blade may be elevated or the wheel elevated to maneuver the blade.，下面是Hand operated wheeled v-blade snowplow专利的具体信息内容。
1. A snowplow comprising a V-shaped scraper blade having a forward apex and rearwardly diverging side portions, said side portions being curled outwardly along the upper rear end portion with a progressively increasing curl from front to rear thereof to provide a concavely curved moldboard to move the snow laterally outwardly at the rear of the blade, said blade being made of a relatively thin, rigid plate type material, a front wheel and a pair of rear side wheels mounted on said blade between said side portions, said front wheel being rearwardly of the forward apex in a centered position and said rear wheels being located equal distances on opposite sides of the longitudinal axis of the blade at the rear end of the side portions for a balanced support of the blade, said blade having a resilient surface-engaging bottom molding portion with a flat bottom surface and an upwardly and inwardly inclined lip portion forming a wedge-like member to move the snow, said front and rear wheels having bottom peripheral surfaces disposed in substantially the plane of the bottom surface of the molding portion, a lateral shaft extending transversely between said side blade portions having end portions coupled to the inner faces of said side blade portions to limit lateral spreading between said side blade portions, a push handle pivotally connected to said support member and extending rearwardly therefrom, an alignment wheel pivotally connected to said support member and extending rearwardly therefrom, a line connected between the front apex portion of the blade and the handle to elevate the front of the blade by pivoting the handle rearwardly and downwardly, and a line connected between the handle and said alignment wheel to selectively elevate the wheel by pivoting the handle forwardly and upwardly.
2. A snowplow comprising a V-shaped scraper blade having a forward apex and rearwardly diverging side portions, said side portions being curled outwardly along the upper end portion with a progressively increasing curl from front to rear thereof to provide a concavely curved moldboard to move the snow laterally outwardly at the rear of the blade, said blade being made of a relatively thin, rigid plate type material, a front wheel and a pair of rear side wheels mounted on said blade between said side portions, said front wheel being rearwardly of the forward apex in a centered position and said rear wheels being located at the rear end of the side portion for a balanced support of the blade, said blade having a resilient surface-engaging bottom molding portion with a flat bottom surface, said front and rear wheels having bottom peripheral surfaces disposed in substantially the plane of the bottom surface of the molding portion, a lateral support member extending transversely between said side blade portions having end portions coupled to said side blade portions to limit lateral spreading between said side blade portions, a push handle pivotally connected to said support member and extending rearwardly therefrom, an alignment wheel pivotally connected to said support member and extending rearwardly therefrom, and means connected between the front apex portion of the blade and the handle to elevate the front of the blade by pivoting the handle rearwardly and downwardly.
3. A snowplow as set forth in claim 2 including a line connected between said scraper blade and said handle to selectively elevate the wheel by pivoting the handle forwardly and upwardly.
4. A snowplow as set forth in claim 2 wherein said support member is a shaft and including a bearing plate rigidly secured to each said side blade portion of the blade into which the ends of said shaft are rotatably supported, said shaft having lateral movement restraining members outwardly of said bearing plates.
5. A snowplow as set forth in claim 2 wherein said molding flat bottom and an upwardly and inwardly inclined lip portion forming a wedge-like member to move the snow.
6. A snowplow as set forth in claim 2 wherein said handle includes a lower bifurcated portion pivotally attached to said lateral support member.
7. A snowplow as set forth in claim 6 including a pair of support arms between said bifurcated portion and freely pivotal on said support member to support said alignment wheel.
