Personal binocular support
First Claim
1. A personal optical-aid holder for suporting an optical aid in relation to the body of a user, during use, comprising:
- a base;
means for securing the base to, and supporting the base from, such user'"'"'s torso exclusively;
a platform adapted to receive and hold such cptical aid;
a mechanical linkage interconnecting the platform and the base, and positioning the platform in relation to the base, so as to substantially support such received and held optical aid in viewing positions substantially at such user'"'"'s eyes;
the linkage being adapted for easy control by such user, without such user'"'"'s raising his or her hands to the viewing positions of such optical aid; and
the linkage being geometrically arranged to translate and rotate such optical aid vertically, under substantially continuous manipulation by such user, to substantially follow movement of such user'"'"'s head and eyes in scanning upwardly from the horizon.

Abstract
This device holds an optical aid such as a pair of binoculars at a user'"'"'s eyes, without the support of the user'"'"'s arms and hands. The user applies only small upward or downward pilot force to a point on the device well below the optical aid. To change or maintain the vertical position of the optical aid the user need not even raise the hands above the chest. The device is mechanically articulated so that, guided only by the pilot force which is simply upward or downward, the optical aid can track and follow the user'"'"'s head and eyes in both position and angle as the user shifts his view up and down between the horizon and the zenith. The device is attached to or worn by the user, while springs or counterbalancing support the weight from the user'"'"'s torso, to free the user'"'"'s arms and hands.

8. A personal optical-aid holder for supporting an optical aid in relation to the body of a user, during use and for tracking the natural arc motion of a user'"'"'s eye position in scanning upwardly from the horizon, and for use with such optical aid that has an eyepiece, said apparatus comprising:
-
a base; means for securing the base to such user'"'"'s body; a platform adapted to receive and hold such optical aid; a mechanical linkage interconnecting the platform and the base, and; positioning the platform in relation to the base, so as to substantially support such received and held optical aid in viewing positions substantially at such user'"'"'s eyes, adapted for easy control by such user, without such user'"'"'s raising his or her hands to the viewing positions of such optical aid, and geometrically arranged to translate and rotate such optical aid vertically, under manipulation by such user, to substantially follow movement of such user'"'"'s head and eyes in scanning upwardly from the horizon, comprising arc-motion generating means that include at least one arm having two ends, one of the ends being pivotally secured to the base so that under manipulation by such user the other of the ends undergoes an arc motion, and also comprising means for conveying to the platform and to such eyepiece at least some part of the arc motion of said other end; and
wherein;the arc-motion generating means further include a second arm pivotally secured to the base, and a driving arm pivotally secured to the base-secured arms;
the base, driving arm and base-secured arms forming a parallelogram; andthe arc-motion conveying means include an extension of the driving arm beyond the parallelogram;
the extension being pivotally secured to the platform at a pivot point on the platform. - View Dependent Claims (9, 10, 11, 12, 13, 14)
