Abstract

An adjustable dressing mirror assembly includes a support, a mirror-mounting unit, and a positioning device. The positioning device includes a guiding seat connected pivotally to the support, a driving plate connected pivotally to the mirror-mounting unit, a sliding block, a movable member, a positioning rod, and a resilient member. The guiding seat includes an accommodating chamber and a plurality of positioning grooves. The driving plate and the sliding block are movable in the accommodating chamber. The positioning rod is disposed fixedly on the movable member. Engagement between the positioning rod and the positioning grooves is allowed with assistance of the resilient member during movement of the driving plate within the accommodating chamber from a rear limit position to a front limit position, and is prevented during movement of the driving plate within the accommodating chamber from the front limit position to the rear limit position.

Claims

1. An adjustable dressing mirror assembly comprising:

a support including two upright rods;

a mirror-mounting unit disposed rotatably between said upright rods of said support in such a manner to allow for forward and rearward pivoting movement of an upper end of said mirror-mounting unit relative to said support;

a mirror disposed on said mirror-mounting unit; and

a positioning device including

a fixed frame disposed fixedly between said upright rods of said support,

an elongated guiding seat including a rear end connected pivotally to said fixed frame, opposite top and bottom plates, and opposite left and right side plates cooperating with said top and bottom plates to define an accommodating chamber, each of said left and right side plates having a guide slot extending along a front-to-rear direction, and a plurality of positioning holes arranged along the front-to-rear direction and in spatial communication with said guide slot,

a driving plate movable forwardly and rearwardly within said accommodating chamber between front and rear limit positions and including a front end connected pivotally to said mirror-mounting unit, and an accommodating hole having a first short top section and a first long bottom section, each of said first short top section and said first long bottom section extending along the front-to-rear direction and being in spatial communication with the other one of said first short top section and said first long bottom section,

a sliding block disposed movably within said accommodating chamber in said guiding seat and co-movable with said driving plate upon forward movement of said driving plate within said accommodating chamber to a predetermined position, said sliding block including a through hole having a second short top section and a second long bottom section, each of said second short top section and said second long bottom section extending along the front-to-rear direction and being in spatial communication with the other one of said second short top section and said second long bottom section,

a movable member disposed movably within said accommodating hole in said driving plate,

a positioning rod disposed fixedly on said movable member and extending along a left-to-right direction, and

a resilient member disposed between said movable member and said driving plate for biasing said positioning rod toward said positioning grooves in said left and right side plates of said guiding seat;

wherein said accommodating hole in said driving plate and said through hole in said sliding block are positioned such that, engagement between said positioning rod and said positioning grooves in each of said left and right side plates of said guiding seat is allowed when said positioning rod is disposed within said first and second short top sections of said accommodating hole and said through hole during movement of said driving plate within said accommodating chamber from the rear limit position to the front limit position, and is prevented when said positioning rod is disposed within said first and second long bottom sections of said accommodating hole and said through hole during movement of said driving plate within said accommodating chamber from the front limit position to the rear limit position.

2. The adjustable dressing mirror assembly as claimed in claim 1, wherein each of said positioning grooves in each of said left and right side plates of said guiding seat is defined by a curved top surface, an inclined rear stop surface extending forwardly and downwardly from a rear end of said curved top surface into said guide slot in a corresponding one of said left and right side plates, and an inclined front guiding surface extending forwardly and downwardly from a front end of said curved top surface into said guide slot in the corresponding one of said left and right side plates.

3. The adjustable dressing mirror assembly as claimed in claim 2, wherein said driving plate further includes a plate body formed with said accommodating hole, and a first insert post extending from said plate body into said accommodating hole, and said movable member further includes a second insert post aligned with said first insert post, said resilient member being configured as a coiled compression spring having a bottom end sleeved on said first insert post, and a top end sleeved on said second insert post.

4. The adjustable dressing mirror assembly as claimed in claim 3, wherein:

said positioning rod is connected fixedly to said movable member at a position behind said second insert post;

said movable member further includes a recess formed in a portion of said movable member disposed in front of said second insert post; and

said driving plate further includes a stop projection extending downwardly from said plate body into said recess in said movable member, so that said positioning rod is biased by said resilient member to move upwardly within said accommodating hole in said driving plate.

5. The adjustable dressing mirror assembly as claimed in claim 4, wherein said sliding block further includes two notches formed in a rear end thereof and arranged one above the other, and said driving plate further includes two driving arms bent laterally from a rear end of said plate body and disposed behind and aligned respectively with said notches in said sliding block, said driving arms being movable forwardly into contact with said sliding block in such a manner to engage said notches, so that said driving plate is moved to said predetermined position for pushing said sliding block forwardly within said accommodating chamber in said guiding seat.

6. The adjustable dressing mirror assembly as claimed in claim 1, wherein said mirror-mounting unit includes a storage cabin housing and a door plate disposed openably on said storage cabin housing, said mirror being disposed fixedly on said door plate, said storage cabin housing including a rear plate and two side plates, said adjustable dressing mirror assembly further comprising two pivotal connection units, each of said pivotal connection units being connected between a respective one of said side plates and a respective one of said upright rods, and including a bracket disposed fixedly on a corresponding one of said upright rods, a rotating block disposed fixedly on a corresponding one of said side plates, a sleeve extending through the corresponding one of said upright rod and said rotating block and into the corresponding one of said side plates such that said bracket is disposed between the corresponding one of said upright rods and the corresponding one of said side plates, a first bolt extending into said sleeve and having a head disposed at one end thereof and a threaded hole formed in the other end thereof, and a second bolt extending into said sleeve to engage said threaded hole in said first bolt for retaining said rotating block on said bracket, in such a manner to allow for rotation of said rotating block relative to said bracket.
