Abstract: Binoculars having a neck strap and a pair of connectors removeably connecting opposite ends of the neck strap to a body of the binoculars. Each connector including a male member and a female member with associated structural members permitting each male member to be used with only one female member. Each male member being fixedly joined to opposite ends of said strap. Each of said connectors being low profile when the members are joined and appearing to be an integrated and structural part of the binoculars body.

Abstract: A control mechanism slidably positions an optical component, such as a focusing lens or a zoom lens, along an optical axis of an optical instrument, such as a telescope or spotting scope. The controller includes a rocker manually rotatable about an axis substantially parallel to the optical axis of the instrument, and an actuating pin rotatably secured to the rocker and extending vertically into the interior of the instrument for actuating a lever arm that reciprocates the optical component. Vertical reciprocating travel of the actuating pin in response to clockwise or counterclockwise rotation of the rocker pivots one end of the lever arm through an angle about a fixed pivot. This rotates a cam on an opposite end of the lever arm through an angle that controls sliding reciprocating travel of the optical component.

Abstract: A riflescope having an internal light source for superimposing an illuminated aiming point on the target field of view. A battery compartment at an eyepiece end of the riflescope is enclosed by a cover and switch assembly to be sheltered from moisture and dust. The switch is easily actuated even when the hunter is wearing heavy gloves, and the cover and switch assembly is in releasable engagement with the battery compartment to enable battery replacement without use of tools.
