Rail Attachment Mechanism
First Claim
Patent Images
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.

2. The method of claim 11, 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 11, wherein the fastener is adhesively coupled to the eccentric hub.
-
4. The method of claim 11, 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.
-
5. The method of claim 11, wherein the rotation of the eccentric hub moves the blade closer to the clamp member.
-
6. 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 respective first rotational positions; rotating the eccentric rotation hub to a second rotational position in which a surface of the blade is in contact with the section of rail; rotating the blade to a third rotational position.
