Abstract

A method for manufacturing an anti-glare rearview mirror is disclosed. An anti-glare rearview mirror has a rectangular bracket and a control lever meshed with the bracket in order to change an angle of a mirror. In manufacturing this rear view mirror, the bracket and the control lever are molded in such a manner that a runner integrally connects the bracket and the control lever without interfering movement of the bracket or the control lever of the assembled anti-glare rearview mirror. And a worker separates the bracket and the control lever at the runner with his hands. Next the worker assembles the bracket and the control lever to a mirror housing without removing a remaining part of the runner.

Claims

1. A method for manufacturing an anti-glare rearview mirror, the rearview mirror including a mirror, a mirror housing for fixing the mirror, a bracket pivotally mounted to the mirror housing, and a control lever pivotally mounted to the mirror housing and engaged with the bracket so as to vary a relative angle between the bracket and the mirror housing by a turning operation of the control lever relative to the mirror housing,

the method comprising the steps of:

molding the bracket and the control lever in such a manner that a runner integrally connects the bracket and the control lever without interfering movement of the bracket or the control lever of the assembled anti-glare rearview mirror;

separating the bracket and the control lever at the runner; and

,

assembling the bracket and the control lever to the mirror housing without removing a remaining part of the runner.

4. A method for manufacturing an anti-glare rearview mirror as claimed in any one of claims 1 to 3,

wherein said runner has a weak section for facilitating a handwork separation of said control lever from said bracket.

2. A method for manufacturing an anti-glare rearview mirror, the rearview mirror including a mirror, a mirror housing for fixing the mirror, a bracket pivotally mounted to the mirror housing, and a control lever pivotally mounted to the mirror housing and engaged with the bracket so as to vary a relative angle between the bracket and the mirror housing by a turning operation of the control lever relative to the mirror housing,

the method comprising the steps of:

molding the bracket and the control lever in such a manner that a runner integrally connects the bracket and the control lever, with engaging portions of the bracket and the control lever faced each other, and that a recess portion is formed in at least one of the bracket or the control lever so as not to interfere movement of the bracket or the control lever of the assembled anti-glare rearview mirror;

separating the bracket and the control lever at the runner; and

, assembling the bracket and the control lever to the mirror housing without removing a remaining part of the runner.

3. A method for manufacturing an anti-glare rearview mirror, the rearview mirror including a mirror, a mirror housing for fixing the mirror, a bracket pivotally mounted to the mirror housing, and a control lever pivotally mounted to the mirror housing and engaged with the bracket so as to vary a relative angle between the bracket and the mirror housing by a turning operation of the control lever relative to the mirror housing,

the method comprising the steps of:

molding the bracket and the control lever in such a manner that a runner integrally connects the bracket and the control lever, with engaging portions of the bracket and the control lever faced each other;

separating the bracket and the control lever at the runner;

engaging the control lever and the bracket without removing a removing part of the runner and with the control lever shifted along a direction of its turning axis with respect to the bracket; and

,

assembling the bracket and the control lever to the mirror housing.
