Abstract
In an ocular support assembly material present in the forward-looking cross-section of the outwardly extending support arms is removed, thereby reducing visual obscuration and enhancing peripheral vision. In the preferred embodiment, the top of each outwardly extending support arm is at or below the middle of the height of the housing, thereby resulting in a low-profile design. At the same time, the support arms are received by the housing with sliding engagement on all sides, thereby eliminating the need for ball bearings or spacers to counteract twisting. The result is a lightweight yet highly stable ocular mounting assembly.
Claims8
An ocular mounting assembly, comprising:
- a housing having a back surface and a hollow through-bore with a height, a horizontal centerline, and opposing open ends, each with an inner wall;
- a pair of support arms, each slidingly received by a respective one of the open ends;
- each support arm including:
- an inner portion including a plurality of teeth that engage with a central gear coupled to an external knob to adjust for interpupillary distance,
- an outer portion having a bottom surface adapted for coupling to an ocular loupe and an upper surface, and
- a central portion having upper and lower surfaces between the inner and outer portions;
- and
- wherein the upper surface of the central portion transitions downwardly to the upper surface of the outer portion.
