US Patent 7845887 Vehicle rail clamp mount

A vehicle rail clamp mount can include a first mount portion that can be engaged with a vehicle rail at any position along the rail. The first mount portion can be positioned to overlie a vehicle rail in transverse to an axis of the rail, then rotated to a position parallel to the rail such that the first mount portion engages the rail. An interlock portion such as a tab on the first mount portion, or a second mount portion can also engage the rail or the first mount portion to prevent the first mount portion from rotating with respect to the rail. The clamp mount device can have a pin or another positioning member to maintain the position of the clamp along the rail. Various accessory mounts can be positioned on the clamp mount.
