Detachable seat mounting for buses

Seating apparatus to be supported upon the floor of a passenger bus, comprising

• a seating device comprising a seating cushion, a back, and a frame, an elongate anchoring track to be affixed on the floor of the bus, a base means on the frame of the seating device to overlie the track and having supporting feet and a locking pin thereon,
• the anchoring track having a rigid bottom and upright side and defining a longitudinally extending open guideway along the length of the track, the track also having a pair of rigid retainer flanges overlying the elongate guideway and arranged in spaced and edge to edge relation with each other and defining an elongate keyway therebetween, the flanges having a plurality of pairs of recesses in the edges thereof at regularly spaced intervals along the track, each pair of recesses being located directly opposite each other and cooperatively defining an enlarged access opening into the guideway,
• the supporting feet having enlarged heads in the guideway and in confronting relation with the flanges to be held by the flanges against upward movement relative to the track, the supporting feet also having narrow necks extending through the keyway to the base means of the seating device, the spacing between the feet equaling the center to center spacing between a pair of such access openings, and the heads being smaller than said openings to pass therethrough, the heads being slidable in the guideway to shift into alignment with the openings for removal therethrough,
• the locking pin being removably inserted into one of the access openings of the guideway to prevent sliding of the feet along the track and to maintain the heads of the feet in confronting relation with the track flanges, the pin engaging and bearing firmly against the bottom of the track, and the pin fitting snugly into the opening of the track to minimize any relative movement between the pin and the track, and pressure means on the base means and supplying significant downward pressure on the locking pin and toward the track, the pressure means including a swingable linkage pivotally attached to a bracket on the base means of the track, the articulated linkage simultaneously causing a downward pressure on the pin and upward pressure on the base means to thereby draw the heads of the feet firmly against the track flanges, the linkage swinging into locked, over-center relation to retain the pin in downwardly oriented position, and a guiding sleeve also affixed to the bracket of the base means and guiding the pin in transverse movement relative to the base means and track for sliding longitudinal movement into and out of the track openings.
