Abstract
A steerable trailer to be drawn by a vehicle is provided that has a generally horizontal frame to which are mounted two wheel supports. Each wheel support is pivotably mounted to the frame to rotate about a vertical axis and to support a wheel rotatably mounted to the wheel support to rotate about a horizontal axis. A steering pulley is also pivotably mounted to the frame to rotate about a vertical axis, and a tongue adapted for temporary attachment to the drawing vehicle is attached to the steering pulley. Any angular displacement imparted to the steering pulley by the drawing vehicle, through the tongue, is communicated from the steering pulley to each wheel support by a flexible tensile member, resulting in a proportional angular displacement of each wheel support. The flexible tensile member forms a continuous FIG. 8 loop to rotate each wheel support in a direction opposite to that of the steering pulley.
