Abstract:
A variable-speed passenger conveyer which changes a transporting speed between a boarding end and a disembarking end by changing the transporting speed of palettes which transport passengers, said conveyer comprising:a pair of guide rails provided in loop fashion with respect to a transporting line so that a width spacing is gradually reduced from the boarding end to a beginning of a high-speed zone and gradually increased from an end of the high-speed zone to the disembarking end;a chain which engages the palettes at said high-speed zone and which drives at a high speed;palettes having engaging metal pieces for engaging said chain and having a spline shaft for sliding said guide roller in a right-angle direction with respect to the transporting direction;a pair of slide blocks engaging the spline shaft of said palettes and moving in a right-angle direction with respect to the transporting direction;a guide roller attached to said pair of slide blocks and guided by said pair of guide rails; anda plurality of link members linking in a planar rhombic form, two pairs of slide blocks adjacent in the transporting direction, and intermediate joints positioned on a center line of said pair of guide rails.
