Abstract
Abstract The invention is a visual alignment aid device that is supported on a towing vehicle to aid in the alignment of the ball on the towing vehicle with the socket in the trailer of the vehicle to be towed, The device includes an elongated tubular shaft having a telescoping shaft sliding and rotationally received therein. The telescoping shaft can be arrested in any position relative to the tubular shaft. The telescoping shaft further has a section with a rigid bend therein. The bend can include an angle of at least 90° and up to 180° depending on the vehicle on which the alignment device is supported. At an end of the telescoping shaft a sleeve is separably mounted which sleeve has an extension which supports a convex mirror in an eccentric fashion.
