[0001] 1. Field of the Invention

[0002] The present invention relates to an auxiliary mirror assembly and, more particularly, to an auxiliary mirror assembly for the sideview mirror of a wheeled vehicle, such as a car and the like.

[0003] 2. Description of the Related Art

[0004] A sideview mirror is mounted on a side of a car to provide a side-viewing effect to a driver in the car to protect the driver's safety. However, the angle of the sideview mirror is usually designed to fit the size of the car, so that when a trailer is attached to the car, the driver in the car cannot clearly see the trailer behind the car, thereby easily causing danger to the driver. A conventional auxiliary mirror assembly for the sideview mirror of a car comprises an auxiliary sideview mirror, a support post mounted on the auxiliary sideview mirror, two mounting brackets adjustably mounted on the support post, and two fastening bolts each extending through the respective mounting bracket and the support post to lock the respective mounting bracket onto the support post. The support post is provided with two guide slots to allow passage and guide movement of the two fastening bolts. Thus, when the two mounting brackets are unlocked from the two fastening bolts, the two mounting brackets are moved on the support post to adjust the distance between the two mounting brackets so that the two mounting brackets can be mounted on a sideview mirror to attach the auxiliary mirror assembly to the sideview mirror.

[0005] In accordance with the present invention, there is provided an auxiliary mirror assembly, comprising an auxiliary sideview mirror, an elongate hollow support post mounted on the auxiliary sideview mirror, two mounting brackets adjustably mounted on the support post, and two locking members each pivotally mounted on the support post and each releasably locked onto a respective one of the two mounting brackets to releasably lock the respective mounting bracket onto the support post. Each of the mounting brackets includes an adjusting member adjustably mounted on the support post and a clamping member pivotally connected with the adjusting member. The adjusting member of each of the mounting brackets has a peripheral wall provided with a serrated portion. Each of the two locking members has an inner face provided with a toothed portion detachably engaged with the serrated portion of a respective one of the mounting brackets.

[0006] The primary objective of the present invention is to provide an auxiliary mirror assembly, wherein the guide rod can guide the movement of the adjusting member of each of the mounting brackets so that the adjusting member of each of the mounting brackets is moved in the slideway of the support post smoothly and stably.

[0007] Another objective of the present invention is to provide an auxiliary mirror assembly, wherein the limit flange of each of the mounting brackets is guided in the guide channel of the support post to guide movement of the adjusting member of each of the mounting brackets and to prevent the adjusting member of each of the mounting brackets from being rotated relative to the support post.

[0008] A further objective of the present invention is to provide an auxiliary mirror assembly, wherein the limit flange of each of the mounting brackets is moved to abut the respective limit screw to prevent the adjusting member of each of the mounting brackets from being detached from the support post.
