Abstract
The invention is a plate with three holes to function as a winch line attachment point and a length and angular adjustment for a chain attached to separated locations on a vehicle. One large hole is used to receive the winch line hook, and two smaller holes with angularly oriented chain locking slots are used to adjust the length of the chain attached to the towed vehicle. The material around the holes is reduced to the minimum size necessary to safely meet the rated towing capacity so that the weight of the plate is minimized.
Claims5
A towing plate for connecting a single winch line to a chain attached to separated points on a vehicle comprising:
- a plate with a centerline, a first edge and a second edge intersecting the centerline at opposite ends of the plate, and two side edges on opposite sides of the centerline, with the edges shaped to form a structure that is balanced on opposite sides of the centerline;
- a first hole formed in the plate, the hole formed so that it is balanced across the plate centerline and has a curved edge intersecting the plate centerline, with the curved edge spaced from the first edge of the plate so that the curved edge and the first edge of the plate form a structure that can accept a hook with which the towing plate is used;
- second and third holes formed in the plate in a balanced configuration across the centerline and located between the first hole and the second edge of the plate;
- and
- two chain locking slots, one slot extending from an edge of each of the second and third holes that is remote from the first hole and extending toward the second edge of the plate, with the slots oriented as balanced across the plate centerline, at equal complimentary angles to the plate centerline, and separating as they approach the second edge of the plate;
- wherein the portions of the plate between the holes between the slots and the edges of the plate, and between the holes and the edges of the plate are reduced in width to a minimum dimension consistent with the rated safe towing capacity of the towing plate.
