Rail attachment mechanism
View Patent ↗A rail mounting mechanism for coupling an auxiliary device to a weapon has an adjuster and a lever that can be used to overcome tolerances in mounting rails to provide a consistent grasp of the rail.
1. A method of setting up an auxiliary device to be mounted on a rail, comprising the steps of:
positioning a section of rail having a predetermined profile between a blade and a clamp member, the clamp member having an axis generally perpendicular to an axis of rotation of the blade;
rotating the blade and an eccentric rotation hub into predetermined first rotational positions;
securing the eccentric rotation hub in place with a fastener;
rotating the blade to a second rotational position;
rotating the eccentric hub to a predetermined minimum torque value; and
securing the fastener to the eccentric rotation hub; wherein the eccentric hub is rotatable about a first axis of rotation and the blade is rotatable about a second axis of rotation, the first axis being parallel with, but spaced from the second axis of rotation.
2. The method of claim 1 , wherein the fastener extends through an opening in the eccentric hub, an opening in the blade, and into an opening on a rail mounting member which is secured to the auxiliary device.
3. The method of claim 1 , wherein the fastener is adhesively coupled to the eccentric hub.
4. The method of claim 1 , wherein the rotation of the eccentric hub moves the blade closer to the clamp member.
