Slim Type Mirror Arm Mechanism with Multi-Position / Stage Ball-Spring Indexing Mechanism

Abstract

The invention relates to a mirror arm mechanism used for opening and closing doors in houses, offices and similar buildings; consisting of a slim mirror arm handle (6), a square shaft (5) connected to the said handle (6), a slim mirror arm inner zinc alloy (2) connected to the square shaft (5), a slim mirror arm sheet metal body (3) working together with the said inner zinc alloy (2), at least 4 positioning holes (11) on the said sheet metal body (3) which provide a stepped rotational movement to the handle (6) formed on the said sheet metal body (3), at least one spring (9) which works in conjunction with these holes, and a ball (10) which is selectively / stepwise placed in the positioning holes (11) under the influence of the said spring (9) which enables the handle (6) to stop at predetermined angular positions (900-1800) during its rotational movement and eliminate mechanical play.
