Locking inter-pupillary distance and convergence adjustment mechanism

Abstract

Improvement to an adornable binocular device having a telescope pair and an adjustable inter-pupillary distance (IPD) where both telescopes move simultaneously and substantially the same distance when the IPD is adjusted, the improvement including a mechanism for releasably preventing unintentional adjustment the IPD and including a first releasably pivoting coupling between each telescope and arm and a second releasably slidable coupling between each telescope and arm.

       21 . An adornable binocular device including:
 a telescope pair;   a housing including teeth;   an inter-pupillary distance (IPD) adjustment mechanism coupled to the housing and configured to move each telescope of the telescope pair relative to a center point; and   a limitation mechanism configured to releasably limit unintentional activation of the IPD adjustment mechanism, the limitation mechanism including teeth releasably mateable with the housing teeth,   wherein the IPD adjustment mechanism is not adjustable when the limitation mechanism teeth are mated with the housing teeth and the IPD adjustment mechanism is adjustable when the limitation mechanism teeth are not mated with the housing teeth.   
   
   
       22 . The adornable binocular device of  claim 21 , wherein the limitation mechanism includes a compression member configured to apply a compressive force from the limitation mechanism teeth to the housing teeth. 
   
   
       23 . The adornable binocular device of  claim 22 , wherein the compression member includes a spring. 
   
   
       24 . The adornable binocular device of  claim 21 , wherein the IPD adjustment mechanism is rotatable and comprises an axis of rotation perpendicular to a rotation plane and the teeth of one of the housing and the limitation mechanism includes peaks that form a plane that is substantially parallel to the rotation plane. 
   
   
       25 . The adornable binocular device of  claim 24 , wherein the IPD adjustment mechanism moves each telescope of the telescope pair simultaneously and substantially the same distance relative to the center point. 
   
   
       26 . The adornable binocular device of  claim 21 , wherein the housing teeth and the limitation mechanism teeth form crown gears. 
   
   
       27 . The adornable binocular device of  claim 26 , wherein at least one of the housing teeth and the limitation mechanism teeth are triangular. 
   
   
       28 . An adornable binocular device including:
 a telescope pair;   two moveable arms with one of the telescope pair attached to each arm;   a housing, the housing holding at least a portion of two moveable arms;   an inter-pupillary distance (IPD) adjustment mechanism coupled to the housing and configured to move each telescope of the telescope pair relative to a center point; and   a limitation mechanism configured to limit the displacement of the moveable arms by releasably applying compressive force from the at least a portion of the two moveable arms to the housing.   
   
   
       29 . The adornable binocular device of  claim 28 , wherein the IPD adjustment mechanism is activated by a rotational force. 
   
   
       30 . The adornable binocular device of  claim 28 , wherein the IPD adjustment mechanism moves each telescope of the telescope pair simultaneously and substantially the same distance relative to the center point. 
   
   
       31 . The adornable binocular device of  claim 28 , wherein the limitation mechanism includes a cam. 
   
   
       32 . An adornable binocular device including:
 a telescope pair;   a housing including teeth;   an inter-pupillary distance (IPD) adjustment mechanism coupled to the housing and including teeth mateable with the housing teeth, the IPD adjustment mechanism configured to move each telescope of the telescope pair relative to a center point; and   a retention mechanism imparting an overcome-able compressive force between the IPD adjustment mechanism teeth and the housing teeth to limit unintentional activation of the IPD adjustment mechanism.   
   
   
       33 . The adornable binocular device of  claim 32 , wherein the retention mechanism includes a spring. 
   
   
       34 . The adornable binocular device of  claim 32 , wherein at least one of the housing and the IPD adjustment mechanism teeth form a crown gear. 
   
   
       35 . The adornable binocular device of  claim 32 , wherein the IPD adjustment mechanism moves each telescope of the telescope pair simultaneously and substantially the same distance relative to the center point. 
   
   
       36 . The adornable binocular device of  claim 32 , wherein the IPD adjustment mechanism is rotatably activated. 
   
   
       37 . The adornable binocular device of  claim 32 , wherein the IPD adjustment mechanism is rotatable and comprises an axis of rotation perpendicular to a rotation plane and the teeth of one of the housing and the IPD adjustment mechanism includes peaks that form a plane that is substantially parallel to the rotation plane. 
   
   
       38 . The adornable binocular device of  claim 37 , wherein at least one of the housing teeth and the IPD adjustment mechanism teeth are triangular.
