Projected magnetic fastening system
According to some embodiments, a railcar comprises an interior wall and guard strips magnetically coupled to the interior wall. Each of the guard strips comprises a cushioning material for absorbing impact. The guard strips are configured to prevent an object loaded in the railcar from contacting the interior wall. The railcar further comprises protected magnetic fastening systems coupling each of the guard strips to the interior wall. Each of the protected magnetic fastening systems comprises a magnet and a rod comprising a first end and a second end. The first end is coupled to the magnet, and the second end extends through the guard strip. The protected magnetic fastening system may further comprise a cup washer coupled to the second end of the rod and secured with a fastener. The cup washer partially surrounds the fastener to restrict objects larger than the cup washer from contacting the fastener.
1. A door edge guard comprising:
a guard strip comprising a cushioning material for absorbing impact and one or more protected magnetic fastening systems;
each of the one or more protected magnetic fastening systems comprising:
a magnet;
a rod comprising a first end and a second end, the first end coupled to the magnet, and the second end extending through the guard strip; and
a cup washer coupled to the second end of the rod and secured with a fastener, the cup washer partially surrounding the fastener to restrict objects larger than the cup washer from contacting the fastener.
2. The door edge guard of claim 1 , wherein the rod comprises a threaded rod and the fastener comprises a nut.
3. The door edge guard of claim 1 , wherein the cup washer comprises a plastic cup washer.
4. The door edge guard of claim 1 , wherein the guard strip comprises a recessed portion and the one or more protected magnetic fastening systems are disposed within the recessed portion.
5. The door edge guard of claim 1 , wherein when the door edge guard is coupled to an interior of an autorack railcar, the door edge guard restricts a door of a vehicle loaded in the autorack railcar from contacting the interior of the autorack railcar when the door is opened.
