Abstract
An apparatus for restraining the movement of a ladder is disclosed. The apparatus is formed of plate which can be attached to roof of a structure using nails or other fastening devices. In one embodiment of the present invention, the plate has a stationary bracket which extends from an edge of the plate. A movable bracket is attached to the plate which also has a portion that extends from the edge of the movable bracket. The stationary bracket and the moveable bracket cooperate to receive and retain the respective side support rails of a ladder when the ladder is leaned against a structure. In a second embodiment, both brackets are movable.

An apparatus for restraining the movement of a ladder, said apparatus comprising:
- a generally flat plate having a top and a bottom surface and being adapted for attachment to the roof of a structure, said plate having a stationary tab formed from said plate and extending from an edge of said plate and being flared upward from said plate;
- a movable tab adapted for attachment to said plate, said movable tab having a portion thereof that extends from an edge of said plate, said portion being flared upward from a plane of said plate;
- and
- wherein said stationary tab and said moveable tab cooperate to receive and retain respective side edges of a ladder when said ladder is leaned against said structure.
An apparatus for restraining the movement of a ladder, said apparatus comprising:
- a generally continuously flat plate having a top and a bottom surface and being adapted for attachment to the roof of a structure, said plate having first and second rotating rail locks mounted adjacent said top surface and when rotated to a first position extends from an edge of said plate and when rotated to a second position does not extend from the edge of said plate;
- and
- wherein when said first and second rotating rail locks are rotated to said first position said rotating rail locks cooperate to receive and retain the respective side support rails of a ladder when said ladder is leaned against said structure.
