Patent ID: 8104217

Claim:
A riflescope high speed, coarse and fine adjustment assembly, comprising: a. a riflescope with a scope body having an erector tube located therein, said scope body including a mounting surface, said mounting surface including a lead screw opening formed therein located adjacent to a proximal end of an erector tube disposed inside said scope body; b. an adjustment plate aligned over said mounting surface, said adjustment plate includes a front section and a rear section, said adjustment plate includes an upward extending, perpendicularly aligned rotating post member with a threaded bore formed therein; c. a lead screw with a threaded head and a lower neck, said threaded head being connected to said threaded bore in said post member of said adjustment plate and said lower neck being inserted into said lead screw opening formed on said mounting surface, when said adjustment plate is positioned over said mounting surface, said lead screw being sufficient in overall length to press against the proximal end of said erector tube and threadingly connect to said post member; d. a cover plate disposed over said adjustment plate, said cover plate includes a front section fixed to said mounting surface and detached at an opposite rear surface, said cover plate includes a fine adjustment lever attached to the rear section and able to be selectively adjusted to extend downward there and contact said adjustment plate thereby enabling a rear edge of said cover plate to be raised or lowered over said adjustment plate, said cover plate also includes an O-ring assembly; e. a detent plate attached over said cover plate and axially aligned over said post member, said detent plate includes at least one outward extending tooth; f. a coarse adjustment dial disposed over said detent plate, said course adjustment dial includes an inner cavity that is engaged by said tooth on said detent plate; and, g. whereby when said coarse adjustment dial is rotated said lead screw extends or retracts into said scope body and move said erector tube to view a desired target distance, said fine adjustment lever on said cover plate may be selectively rotated which causes the rear section of said adjustment plate to raise or lower with respect to said cover plate thereby finely adjusting the length of said lead screw that extends into said scope body and finely move said erector tube up and down inside said scope body.
