HANDLE DEVICE FOR A LADDER |
摘要 |
This invention relates to ladder accessories, in particular a handle device which is attached to the ladder and can be moved upwardly or downwardly along the ladder as the ladder user ascends or descends. The device includes a mechanism for gripping both side rails of the ladder and a mechanism for releasably engaging holes formed in one side of one of the side rails. A handle member is rigidly attached to the gripping mechanism and permits a user to manually hold onto the device. The preferred engaging mechanism is a pivotable engagement member mounted on one side of the gripping mechanism and a spring which biases the engagement member to a position where one end thereof engages a side of one of the holes in the side rail. The preferred gripping mechanism includes two connecting bars that extend horizontally and are adjustable in length.
