Abstract

An improved jack assembly for use with a trailer tongue of a towed vehicle. The jack assembly including telescoping height adjustment of the assembly, a pivot assembly for pivoting between a vertical and horizontal stowed position, and a clip for maintaining a handle assembly in a stowed position when not in use. The jack assembly also includes the use of bushings for the telescoping tubes to enhance the sliding movement between the tubes and aid in maintaining the axial alignment of the tubes thereby extending the life of the jack assembly. The pivot assembly further includes an attachment bracket that may be rotated to accommodate at least two different sizes of trailer tongues.
