摘要：A sliding door includes a roller lifting mechanism provided by horizontallyspaced bell cranks to which rollers are connected and which may be pivoted downwardlyto engage a door track for raising the door so that it may be laterally moved to one sideof the door opening. The lifting mechanism includes a cam element which is manuallyrotated to exert a push force on the bell crank levers for pivoting the same into the liftposition. A modified version of the lift mechanism includes a linkage arrangement whichexerts a pulling action on the bell cranks for achieving the lifting function.
