发明名称 Ladder bracket
摘要 A ladder bracket for attachment to the side rails of a ladder to allow the ladder to be used against the side of a building or structure without causing damage to the gutters, eave troughs, etc. The ladder bracket distributes the weight of the ladder and user onto the roof surface by a pivoting bearing surface which accommodates all roof pitches. The ladder bracket does not rely upon the structure of the rungs of a ladder for positioning or support. This makes this ladder bracket infinitely adjustable along the length of the side rail. The sleeve of the bracket is slightly larger in dimension than the width of the side rail and thus, when load is placed upon the ladder, the bracket pivots slighltly outward relative to the building or structure. This pivoting action causes the bracket to lock against the side rail and prevents slippage.
