Ladder Stop and Method
A ladder stop for securing a ladder vehicle rack includes a hook that contacts the ladder and holds the ladder to the rack. The stop includes a clamp which removably attaches to the rack and from which the hook rotates and extends and moves up and down to hold the ladder. The stop includes a locking mechanism that locks the hook in a desired position. The stop includes a handle disposed adjacent a bottom of the hook for a user to grab and pull the hook down to secure the hook in place with the ladder. A method for securing a ladder to a vehicle rack.
1 . A ladder stop for securing a ladder to a vehicle rack comprising:
a hook that contacts the ladder and holds the ladder to the rack;
a clamp which removably attaches to the rack and from which hook rotates and extends and moves up and down to hold the ladder;
a locking mechanism that locks the hook in a desired position; and
a handle disposed adjacent a bottom of the hook for a user to grab and pull the hook down to secure the hook in place with the ladder.
2 . The ladder stop of claim 1 wherein the hook has a long arm and a short arm and a center member connected to and between the long arm and the short arm, the long arm and short arm in parallel and spaced relation, the short arm shorter in length than the long arm, the long and short arms and center portion are one continuous piece, the long arm extending through the clamp and able to rotate in and move up and down the clamp so the short arm can be positioned about the ladder, with the ladder disposed between the short arm and the long arm to secure the ladder to the rack.
3 . The ladder stop of claim 2 wherein the clamp include a body having a center portion, a top flange extending from the center portion and a bottom flange extending from the center portion, with the center portion between the top flange and the bottom flange, the top flange having a hole through which the long arm extends in the bottom flange having a hole through which the long arm extends, the hole of the top flange in alignment with the hole of the bottom flange.
4 . The ladder stop of claim 3 wherein the locking mechanism includes a spring positioned about the long arm and disposed on the bottom flange, and a friction plate having a hole through which the long arm extends so the friction plate can move up and down the long arm, the friction plate having a free end and an engagement end which contacts the center portion and pushes against the center portion from the force of the spring, which is disposed below and in contact with the friction plate, the engagement end of the friction plate locking the clamp in position on the long arm unless the free end of the friction plate is pushed down which releases the engagement end from contact with the center portion so the body is able to move up and down the long arm as long as the free end is pushed down.
5 . The ladder stop of claim 4 wherein the clamp has a base with a circular shaped opening which conforms with a circular shaped rail of the rack and receives the rail when the clamp is attached to the rack, the center portion disposed between the base and the long arm, the clamp has a strap attached to the base above the circular shaped opening, and a knob with a threaded end, the strap has a bottom portion through which the threaded end of the knob extends, the base having a receiver disposed below the circular shaped opening which receives the threaded and of the knob, the strap wrapping around the rail when the rail, is disposed in the circular shaped opening and securing the clamp to the rail when the threaded end of the knob is disposed in the receiver.
6 . The ladder stop of claim 5 wherein the handle is a bar that extends adjacent the bottom of the long arm.
7 . A method for securing a ladder to a vehicle rack comprising the steps of:
placing a rail of the rack in a clamp of a ladder stop;
attaching the clamp to the rail;
putting a locking mechanism of the ladder stop in an unlocked state;
moving a hook of the ladder stop down so the hook holds the ladder to the rack while the locking mechanism is in the unlocked state; and
putting the locking mechanism into locked state so the hook cannot move and the ladder is secured to the rack.
8 . The method of claim 7 wherein the moving the hook step includes the step of positioning a short arm of the hook about the ladder so the ladder is positioned between the short arm and a long arm of the hook.
9 . The method of claim 8 wherein the attaching step includes the step of placing the rail of the rack into a circular shaped opening of a base of a body of the clamp, wrapping a strap attached to the body above the circular shaped opening about the rod, and attaching a threaded and of a knob that extends through a bottom of the strap into a receiver in the body located below the circular shaped opening to clamp the clamp to the rack.
10 . The method of claim 9 wherein the step of putting the locking mechanism of the ladder stop in the unlocked includes the step of pressing down on a free end of a friction plate through which the long arm extends causing an engagement end of the friction plate to move out of contact with a center portion of the base of the body so the center portion, which is movably attached to the long arm through an upper flange and a lower flange that extends from the center portion, is able to move up and down relative to the long arm.
11 . The method of claim 10 wherein the step of putting the locking mechanism into the locked state so the hook cannot move and the ladder is secured to the rack includes the step of releasing the free end of the friction plate so a spring positioned about the long arm and disposed on the lower flange biases the engagement end against the center portion and holds the long arm in place with the clamp.
