Adjustable throw-lever picatinny rail clamp
First Claim
1. An adjustable mounting system, comprising:
- a mounting rail attached to a structure and defining a plurality of upwardly facing mounting projections each having oppositely angulated clamping surfaces;
at least one mounting base having an angulated clamp surface and defining a locking platform having a lock opening therein;
a locking lever having a rotary cam plate and a pivot shaft integral therewith, said pivot shaft being rotatable within said lock opening, said rotary cam plate having a peripheral angulated cam surface being moveable into force transmitting locking engagement with one of said oppositely angulated clamp surfaces upon rotation of said locking lever and cam plate from an unlocking position to a locking position; and
an adjustment nut being threaded to said pivot shaft and upon rotation on said pivot shaft adjusting the locking position of said rotary cam plate relative to one of said oppositely angulated clamp surfaces.

Abstract
A throw-lever releasable mounting system for mounting a device in quick-release relation to a support member has a mounting base having a configuration fitting opposed angulated rail surfaces and having a locator key engaging a positioning slot of the rail. Each mounting base provides for mounting and stabilization of optics mounting rings. A locking platform projects from the mounting base and defines a locking opening having a circular hard metal insert therein that defines a receptacle receiving a resilient member and providing for location of the spline/spindle shaft of a rotatable locking plate. A locking plate of a throw-lever that is rotatable between locking and unlocking positions has angulated and curved cam surfaces for forcibly engaging correspondingly angulated surfaces of the rail to achieve cam energized precision locating and locking engagement with the rail. A non-circular section of a spline/spindle shaft of the throw-lever is receives a drive member in non-rotatable and linearly moveable relation. Resilient members are interposed between the drive member and the hardened insert and prevent free throw-lever movement at the release position thereof.

22. A mounting system for mounting an optical sighting device to a firearm, comprising:
-
a mounting base adapted for mounting in fixed relation with a firearm, a mounting pedestal projecting from said mounting base and having spaced transverse bores extending therethrough;
a pair of mounting ring sections defining internal arcuate surfaces for frictional retaining engagement with an optical sighting device and defining spaced insert openings;
hardened internally threaded insert members being received within said spaced insert openings and having portions thereof received within said spaced transverse bores; and
retainer screws extending through said mounting ring sections and having threaded engagement within said hardened internally threaded insert members and retaining said mounting ring sections in immoveable and accurately positioned assembly with said support pedestal. - View Dependent Claims (23, 24, 25)
