    Abstract: A sliding door includes a roller lifting mechanism provided by horizontally spaced bell cranks to which rollers are connected and which may be pivoted downwardly to engage a door track for raising the door so that it may be laterally moved to one side of the door opening. The lifting mechanism includes a cam element which is manually rotated to exert a push force on the bell crank levers for pivoting the same into the lift position. A modified version of the lift mechanism includes a linkage arrangement which exerts a pulling action on the bell cranks for achieving the lifting function.

    Abstract: A gate slidable along and pivotal on a stanchion carries a roller engaging a cam surface on a cam block to close the gate and stop the gate in a closed position. The block is rotatable on the stanchion and is connected by torsion rods to a collar fixed to the stanchion.
