发明名称 Ladder locking means
摘要 A locking device is provided for preventing the theft of a ladder from a job site and is used in combination with a tool storage chest or tool box. First and second locking members are extended through opposite sides of the tool box with one of the locking members passing through a ladder positioned adjacent the tool box. The inner ends of the first and second locking members telescopically receive one another and a locking pin extends through the telescoping inner ends to secure the ladder in place. When the access door to the tool box is locked, access to the locking pin is prevented.
