  • Patent number: 5421428
    Abstract: The invention is a ladder guard which prevents unauthorized access to a ladder. Preventing injury to children is a primary goal of the invention. The ladder guard has a top and a bottom hook extending from two metal sheets. The hooks can be adjusted to go between two to four ladder rungs, thus preventing use of the covered rungs. The top and bottom hooks are adjustable to fit any size rungs. The metal sheets may be locked to prevent removal. A tool tray is also mountable when the ladder is in use. The invention works with all known ladders. It is, therefore, a removable universal fitting ladder guard.
