发明名称 Anti-slip attachment for ladders
摘要 An anti-slip attachment for a ladder that forms a frictional engagement between the ladder and a metal gutter, so as to prevent the ladder from slipping laterally thereon. A layer of resiliently compressible material having a high surface coefficient of friction against smooth metal is mounted to the ladder so that it will bear against and be compressed by an edge of the gutter. The layer of resiliently compressible material may be at least one strip of resiliently compressible foam tape. The resiliently compressible material may be adhered directly to the side rails of the ladder so as to bear against the edge of a gutter when the ladder is rested thereon, or the layer or layers of resiliently compressible material may be mounted to a separate frame or bracket that is in turn mounted to the ladder itself. The anti-slip attachment helps to reduce the likelihood of fall injuries due to the ladder slipping sideways along a metal gutter during use.
