LADDER SAFETY DEVICE HAVING A BUILDING CLAMP ASSEMBLY AND A LADDER HOOK ASSEMBLY
A house clamp assembly having a fixed jaw and a slide bar mounted movable jaw, the fixed jaw opposing the movable jaw. A one-way drive means, by operation of a trigger handle grip, releasably engages the slide bar and advances the movable jaw towards the fixed jaw. The one-way drive means is incapable of moving the slide bar and movable jaw away from the fixed jaw. A return motion of the movable jaw (separating) is accomplished manually when the one-way drive means is disengaged. A braking lever, which is biased to bind the slide bar, prevents reverse motion of the slideable jaw away from the fixed jaw, except when the first lever is disengaged from the slide bar. A device for securing a ladder to a building, wherein the removed end of the slide member has a hook shape; wherein the jaws include jaw faces having multiple raised portions, wherein the releasable braking means of the building clamp assembly means includes a pivoting lever; wherein the locking member of the ladder hook assembly includes a pivoting lever, attached at one end to the body, and having a slot dimensioned to slideably receive the hook slide member therethrough; wherein the body of the ladder hook assembly includes a pair of slots dimensioned for and adapted to slideably receive the slide member therethrough; and wherein the slots are arranged to maintain the hook slide member substantially parallel to the slide bar of the building clamp assembly
