发明名称 Tool for retrieving a ladder from an elevated position
摘要 A ladder removal tool designed for use with any ladder that is supported at an elevated position and the method of its use are disclosed. The ladder may be an extension ladder or a large "A" frame ladder. The ladder removal consists of a lifting rod that has hook connected to one end by a pivot joint that allows the hook to rotate with respect to the lifting rod. The lifting rod has a substantially right angle bend adjacent the pivot joint to aid the user in reaching up and "hooking" or engaging the hook with a rung of the ladder to be lowered. The opposite end of the lifting rod has a handle attached thereto. Additionally, the leg of the hook attached to the lifting rod has a stabilizer arm attached thereto. The user reaches up and inserts the hook of the tool around a rung of the ladder while simultaneously allowing the stabilizer arm to extend over and engage the side rail of the ladder. Generally, the user lifts one end of the ladder clear of the rack, swings the ladder away from the truck and lowers the ladder to the ground, while the opposite end rotates around the safety bar on the rack. The user can then use the ladder removal tool to lift the opposite end and lower it to the ground. If desired, the user may use the tool to replace the ladder on the vehicle by simply reversing the order of operation.
