Abstract
A fastening system for track rail includes a track rail fastener positionable upon a pedestal mount, and including a top plate, a frame, and an overmolded jacket. The system further includes a lateral positioner having an eccentric structured to contact a pedestal mount, and a locating pin extending through the fastener body and the eccentric to couple a lateral location of the fastener body to an angular orientation of the eccentric, such that rotating the eccentric varies a lateral location of the fastener body. A frame in the fastener body includes a plurality of vertically extending finger walls for lateral and rotational stability, with the overmolded jacket extending between the finger walls and the top plate.

A fastening system for track rail comprising:
- a pedestal mount including a pedestal plate, and a pair of laterally extending pedestal legs structured to support the pedestal plate above a substrate;
- a track rail fastener positioned upon the pedestal mount and including a fastener body having a top plate, a frame, an overmolded jacket encasing the top plate and the frame, and an upper rail contact surface extending in a fore-aft direction;
- a lateral positioner including a locating pin, and a positioner body including a locating surface extending circumferentially around a body axis, and a bore extending axially through the positioner body and eccentrically arranged with respect to the locating surface;
- the locating surface contacting the pedestal mount such that a lateral location of the body axis is fixed relative to the pedestal mount;
- the locating pin extending through the fastener body and the bore such that a lateral location of the track rail fastener relative to the pedestal mount is coupled to a lateral location of the bore relative to the pedestal mount;
- and
- the positioner body is at a first angular orientation about the body axis at which the bore has a first lateral location relative to the pedestal mount, and is adjustable to a second angular orientation at which the bore has a second lateral location relative to the pedestal mount to reposition the track rail fastener based on the coupling of the lateral location of the track rail fastener to the lateral location of the bore.
A track rail fastener comprising:
- a fastener body having a top plate, a frame, an overmolded jacket encasing the top plate and the frame, and an upper rail contact surface extending in a fore-aft direction;
- a lateral positioner including a positioner body having a locating surface extending around a body axis, a bore extending axially through the positioner body, and a locating pin extending through the fastener body and the bore;
- and
- the bore being eccentrically arranged with respect to the locating surface, and the positioner body being rotatable upon the locating pin, such that a change to an angular orientation of the bore about the body axis is coupled to a change to a lateral location of the fastener body relative to the body axis.
A track rail fastener comprising:
- a fastener body having a top plate, a frame, an overmolded jacket, and an upper rail contact surface extending in a fore-aft direction;
- a lateral positioner including a positioner body having an eccentric structured to contact a pedestal mount and defining a body axis, and a locating pin structured to extend through the fastener body and the eccentric, to couple a lateral location of the fastener body relative to the body axis to an angular orientation of the eccentric about the locating pin;
- the frame including a plurality of vertically extending finger walls;
- and
- the overmolded jacket encasing the top plate and the frame and extending between the top plate and each of the plurality of vertically extending finger walls.
