发明名称 Sidewalk and curb crevice weeder
摘要 A crack and crevice weeder device for cleaning undesirable growth from cracks or crevices in sidewalks and expansion joints between sidewalk and street. A V-shaped cutting head is attached to an end of an U-shaped steel rod and a triangular-shaped scraper is attached to a point on the U-shaped rod. The U-shaped rod is fixed to a long handle which enables an operator, while standing, to remove undesirable growth from cracks, crevices or expansion joints by pulling the weeder towards him while simultaneously applying a downward pressure.
