Vehicle door
First Claim
1. In combination, a mass transit vehicle having a sliding door, comprising upper track means suspended downwardly and resiliently mounted on the upper frame of said vehicle, lower track means extending outwardly and rigidly mounted on the lower frame of said vehicle, lower suspending means mounted on said door and slidingly cooperating with said lower track means, upper guide means mounted on said door and slidingly cooperating with said upper track means, and means for causing said door to move between an open and a closed position along said track means, each of said track means comprising linear bearing rod means affixed to a plurality of spaced apart mounting blocks which, in turn, are secured to said vehicle such that said linear bearing means are essentially parallel to the longitudinal axis of said vehicle, said upper track means comprising an upper track support fixed to the upper frame of said vehicle in a horizontal plane and upper mounting blocks suspended from, and resiliently mounted to, said upper track support, and said lower track means comprising a lower track support fixed to the lower frame of said vehicle in a vertical plane and lower mounting blocks extending outwardly from, and rigidly mounted to, said lower track support.
