Sub frame support system and running board for a vehicle

A sub frame support system for releasably mounting an accessory to a vehicle, comprising:

• an elongate receiving frame;
• brackets mountable to a vehicle frame and to the receiving frame at selected positions along its length for fixedly mounting the elongate receiving frame at a selected position relative to the vehicle frame;
• a pair of cylindrical mounts fixed in spaced relation to the receiving frame;
• a pair of elongate mounts configured to fit the cylindrical mounts;
• a running board and said elongate mounts pivotally mounted about a vertical pivot to said running board and spaced to fit the cylindrical mounts whereby pivoting of the elongate mounts facilitates alignment for removable mounting of the elongate member to the receiving frame;
• and
• a releasable lock for releasably locking the cylindrical mounts to the elongate mounts for securing the running board to the receiving frame.

A running board assembly for a vehicle comprising;

• a pair of cylindrical mounts mountable at fixed space positions to a vehicle frame of said vehicle;
• an elongate running board having a receiving bore at each end;
• a configured support member for each end, said support member having one end inserted into the receiving bore of the running board and having a second end inserted into one of the cylindrical mounts, said receiving bore being oversized relative to said inserted end and a fastening pin vertically extended down through the running board and support member end to pivotally connect the support member end to said running board end and thereby provide limited pivoting of said support member relative to said running board as permitted by the oversized receiving bore;
• a releasable fastener fastening said second end of said support member to said cylindrical mount to provide for selective removal and remounting of said running board to the vehicle.
