  • Patent number: 6592134
    Abstract: Method and apparatus for removably affixing a wheel assembly (20) near the end and the edge of a leg (24,27) of nearly any existing or newly manufactured ladder (22) to aid a person (26) transporting the ladder (22). A preferred embodiment includes a first wheel (30a) and a second wheel (30b) whose axles (32a, 32b) are disposed orthogonally. Each axle (32a, 32b) is supported by a bracket (34a, 34b) coupled to a clamp frame (36) which is clamped to said leg (24,27). When the ladder (22) is placed, edge parallel to a supporting surface (28), and a person (26) carries the opposite end of the ladder, the wheel (30b) will roll on that surface (28). When the ladder (22) face is placed parallel to a supporting surface (28) and a person (26) carries the opposite end of the ladder, the wheel (30a) will roll on that surface (28). The wheel (30a, 30b) will carry a large portion of the weight of the ladder (22). For persons who use ladders frequently, the system can prevent personal injuries.
