Abstract

Abstract The invention relates to a rear view mirror extension device for use with vehicles such as light duty trucks and the like which have, as standard equipment, a mirror connected to a tubular support arm secured to a mounting bracket on the vehicle door. The device includes an inverted U-shaped extension member having one leg thereof rotatably received in the vehicle mount in place of the original support arm. The support arm and the other leg of the extension member are each rotatably received in a clamp member. By suitably rotating the extension member and the clamp member relative to each other and the vehicle the mirror can be moved from a position closely approximating its original position near the vehicle to an extended position wherein it is spaced outwardly from the vehicle by the extension and clamp members. The driver can adjust the position of the mirror outwardly to compensate for wide loads or tows which would otherwise unduly obstruct his rearward view.
