Abstract

An ocular mounting assembly for adjustably mounting a pair of ocular devices, such as telemicroscopic loupes, to an eyeglass frame or head mount with linear and rotational adjustments, but with view angle being permanently preset in accordance with working distance. The ocular mounting assembly includes an adjustable ocular support assembly and an adjustable clamp assembly rotatably attached to the ocular support assembly. The ocular mounting assembly includes a housing and two slidable mounting arms to which the ocular devices are attached, the transverse cross-sectional shape of the housing interior and mounting arms being such that substantially all of the volume of the housing interior is consumed apart from close tolerances to facilitate the sliding motion, thus resulting in a structure which cooperates to assist in providing a substantially rigid assembly. The adjustable clamp assembly provides height and view angle adjustment of the ocular devices and allows the ocular devices to be flipped up out of the way when not needed. The height adjustment in conjunction with the view angle adjustment allows the line of sight to be adjusted while the ocular devices are positioned close to the eye or eyeglass lens.

Claims

1. A head-mounted ocular assembly, comprising:

an ocular support assembly including a pair of slidably disposed ocular support arms, each with an end for supporting a pair of ocular devices rotatably attached to the ends of the ocular support arms, each ocular support arm including a set of serrated teeth;

an interpupillary adjustment knob having a gear with teeth that physically engage with the serrated teeth of the ocular support arms, whereby rotation of the interpupillary adjustment knob causes the ocular support arms to slide in and out of the assembly housing for adjustment of the interpupillary distance between the two ocular devices;

a clamp assembly which frictionally engages a pair of view-angle hinge pins defining a first axis of rotational freedom and a pair of flip-up hinge pins defining a second axis of rotational freedom, the two axes of rotational freedom being spaced apart and parallel to one another, wherein view angle is adjusted by rotating the ocular support assembly about the first axis, and the ocular devices are flipped up by rotating the ocular support assembly and clamp assembly members about the second axis;

a height adjustment rail coupled to the clamp assembly through the flip-up hinge pins; and

a head mount to which the assembly attaches through the height adjustment rail.
