ABSTRACT:
A snow broom (10) includes a scraper element (12) and multiple sweeping elements (26, 36) positioned on opposite sides thereof. The scraper element (12) is in the preferred form of a sheet of relatively stiff plastic and includes serrations (22) formed on its lower edge (16). The lower edge (16) of the scraper element (12) is divided into a plurality of tines by cuts (24) extending from the lower edge (16). The inner sweeping elements (26) positioned adjacent to and on opposite sides of the scraper element (12) are formed from a sheet of foamed plastic of a flexibility to conform to the surface being swept and having a lower edge (30) parallel to and spaced slightly above the lower edge (16) of the scraper element (12). The outer sweeping elements (36) are formed from a sheet of extruded plastic to which snow does not have an affinity to stick. In addition to providing a sweeping function, the outer sweeping elements (36) provide protection and stiffening for the inner sweeping elements (26). The scraper and sweeping elements (12, 26, 36) are attached together in a stacked arrangement and are secured to a handle (46) by a shroud (54), with the handle (46) extending at a nonperpendicular angle to the lower edges (16, 30, 40) of the scraper and sweeping elements (12, 26, 36).
