Abstract
Abstract A mirror mounting unit designed to function along side an existing mirror to provide a back-of-the-head viewing system. The unit is composed of a bracket having a vertical bar upon which is slideably and rotatably mounted an extendible arm having on one end thereof one portion of a ball and socket retainer and a hand mirror with handle, having on one end of the handle the other portion of the retainer, such that the mirror may be rotatably suspended thereby.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
299 words
In a back-of-the-head viewing system having a first mirror, means supporting said first mirror in a substantially vertical plane, a bracket positioned adjacent said first mirror and including an upper substantially horizontally disposed support rod and a substantially vertically disposed mounting rod, an extensible arm, arm mounting means secured adjacent a first end of said arm and slidably mounting said arm on said mounting rod, a second mirror, and universal mounting means demountably attaching said second mirror to said arm adjacent a second end thereof, the improvement comprising: said arm mounting means being formed as a sleeve-like element secured to said arm and formed with a pair of opposed jaws oriented on planes generally perpendicularly to said arm and extending vertically over the length of said element to define a vertically extending opening in a side of said element, said opening being dimensioned for slidable mounting and removal of said arm from said mounting rod and remounting of said arm on said support rod for storage thereof, said jaws further being formed to grippingly engage said mounting rod at vertically spaced points on opposite sides thereof upon rotation of said element about a horizontal axis under the weight of said arm and formed to be released from said mounting rod upon unweighting of said arm for selected vertical adjustment and automatic gravity actuated gripping of said mounting rod at any vertical height on said mounting rod, and said jaws being formed for rotation of said arm about said mounting rod while maintaining gripping engagement with said mounting rod; and said second mirror being provided with handle means and formed for selective removal from said arm for use separately of said system, said handle means being formed with support rod engaging means for mounting on said support rod for storage.
Claim 2
Dependent Claim
299 words
In a back-of-the-head viewing system having a first mirror, means supporting said first mirror in a substantially vertical plane, a bracket positioned adjacent said first mirror and including an upper substantially horizontally disposed support rod and a substantially vertically disposed mounting rod, an extensible arm, arm mounting means secured adjacent a first end of said arm and slidably mounting said arm on said mounting rod, a second mirror, and universal mounting means demountably attaching said second mirror to said arm adjacent a second end thereof, the improvement comprising: said arm mounting means being formed as a sleeve-like element secured to said arm and formed with a pair of opposed jaws oriented on planes generally perpendicularly to said arm and extending vertically over the length of said element to define a vertically extending opening in a side of said element, said opening being dimensioned for slidable mounting and removal of said arm from said mounting rod and remounting of said arm on said support rod for storage thereof, said jaws further being formed to grippingly engage said mounting rod at vertically spaced points on opposite sides thereof upon rotation of said element about a horizontal axis under the weight of said arm and formed to be released from said mounting rod upon unweighting of said arm for selected vertical adjustment and automatic gravity actuated gripping of said mounting rod at any vertical height on said mounting rod, and said jaws being formed for rotation of said arm about said mounting rod while maintaining gripping engagement with said mounting rod; and said second mirror being provided with handle means and formed for selective removal from said arm for use separately of said system, said handle means being formed with support rod engaging means for mounting on said support rod for storage.
Claim 3
Dependent Claim
82 words
A back-of-the-head viewing system as defined in claim 1 wherein, said arm mounting means is provided with spring biasing means carried by said jaws, said spring biasing means being formed with a resiliently movable portion retaining said element and said arm on said mounting rod and said support rod against inadvertent demounting therefrom, said movable portion being formed for selective resilient displacement to mount and demount said arm from said mounting rod and said support rod to provide a snap mount thereto.
Claim 4
Dependent Claim
137 words
A back-of-the-head viewing system as defined in claim 1 wherein, said universal mounting means is provided by a ball element mounted on said handle means of sAid second mirror and a socket mounted on said arm having a ball receiving opening, a side channel, a downwardly facing opening, and three retaining elements dimensioned to prevent passage of said ball element downwardly therepast and dimensioned to engage and support said ball element at a plane adjacent to, below and substantially parallel to a horizontal plane passing through the center of said ball element to frictionally damp relative movement of said arm and said second mirror by wedging action between said retaining elements and ball element whereby said second mirror is mounted in said socket for selective movement therein and is frictionally damped to a stable position by gravity.
