Vehicle ladder attachment mechanism
A system is provided for interconnecting a ladder to a vehicle. The system may include a first portion for interconnecting to an upper portion of a vehicle rear door and a second portion for interconnecting to a lower portion of the vehicle rear door. The system provides a ladder interconnection wherein no penetrations are made into the vehicle.
1. A clamp system for interconnecting a ladder to a lower portion of a rear door of a vehicle, comprising:
a fastener;
a clamp, comprising:
a first plate that is generally planar with an upper surface and a lower surface, wherein the upper surface is adapted to be positioned adjacent to a lower edge of the rear door when the clamp is interconnected to the rear door, wherein the first plate has a first width;
a second plate that is generally planar and that extends upwardly from the upper surface of the first plate, the second plate having an inner surface and an outer surface, wherein the inner surface is adapted to be positioned proximate to an outer surface of the rear door when the clamp is interconnected to the rear door;
a first flange extending upwardly from the upper surface of the first plate and including a first aperture oriented toward the second plate;
a second flange extending upwardly from the upper surface of the first plate and including a second aperture oriented toward the second plate; and
a third plate extending outwardly from the outer surface of the second plate and away from the first and second flanges, wherein the third plate includes an aperture for the fastener, the aperture spaced from the second plate by a predetermined distance, and wherein the third plate has a third width approximately equal to the first width; and
the ladder comprising a lower bracket adapted to be positioned proximate to the third plate, the lower bracket comprising a hole that is alignable with the aperture of the third plate, wherein the fastener is operable to extend through the aperture and into the hole to interconnect the ladder to the third plate.
2. The clamp system of claim 1 , wherein the first plate extends from a first edge to a second edge opposite to the first edge, the first edge spaced from the second edge by the first width of the first plate, wherein the second plate has a second width approximately equal to the first width.
3. The clamp system of claim 1 , wherein the second plate has a second width, and wherein the third width is approximately equal to the second width.
4. The clamp system of claim 1 , wherein the third plate is oriented approximately perpendicular to the second plate.
5. The clamp system of claim 1 , further comprising a pinch plate selectively engaged by screws extending through the first and second apertures, wherein the pinch plate is positioned proximate to an inner surface of the rear door when the clamp is interconnected to the rear door.
6. The clamp system of claim 1 , wherein:
the first plate has a first thickness;
the second plate has a second thickness; and
the third plate has a third thickness, the third thickness being approximately equal to the first thickness.
7. The clamp system of claim 1 , wherein the first and second flanges are approximately perpendicular to the first plate, and wherein the second plate is approximately perpendicular to the first plate.
