DURABLE QUICK INSTALL/RELEASE ERGONOMICALLY EFFICIENT LIGHT OBSCURING COVER FOR CONTROLLING RETICLE BRIGHTNESS IN FIBER OPTIC MEDIUM LIGHT CONDUIT SIGHTS

摘要

Exemplary apparatuses and methods are provided which provide an ability for rapid manipulation of a light obscuring cover to control brightness of an optical medium based sight assembly reticle projector. Shapes or portions of an exemplary cover can be formed to provide structural elements oriented, shaped, and positioned within a range of motion distance of a user's normal finger or hand positions on an equipment item, e.g. a weapon, suitable for rapid manipulation or repositioning of the cover by a user while minimizing accidental manipulation or movement. The light obscuring cover may flexibly conform and grip to sections of the sight assembly to cover the fiber optic cable or medium. In one embodiment, the apparatus further comprises a lanyard element configured for attaching the light obscuring cover to the scope and thereby be used to manipulate, locate, adjust, or arrest the cover's motion in relation to the sight assembly.

主权项

1. A sight assembly comprising:
a sight comprising a sight housing, a mounting section formed onto a first sight housing section adapted to couple said sight assembly with another structure, a fiber optic housing comprising a first and second wall section formed on and extending away from a second sight housing section, a fiber optic line disposed between said first and second wall sections and extending into said sight housing through an aperture in said sight housing, a plurality of lenses comprising at least a first lens disposed within a hollow cavity of said sight housing along an optical axis, wherein said fiber optic line is adapted to convey light from an external section of said sight into said hollow cavity of said sight onto said first lens; and a light obscuring cover comprising a first, second, and third section;
wherein said second section is formed in a shape conforming to and adapted for covering an external section of said fiber optic line and at least some of said first and second wall sections of said fiber optic housing section;wherein said first and second sections are formed with a first interface section which comprises a first angled section of said cover formed so that said first section extends away from said second section at a first angle that is less than 180 degrees;wherein said second and third sections are formed with a second interface section which comprises a second angled section of said cover formed so that said third section extends away from an opposing side of said second section at a second angle that is less than 180 degrees;wherein at least said first and third sections are formed such that they mechanically couple with said fiber optic housing sides with a flexible interference fit adapted to grip said fiber optic housing up to a first friction force.
