Embodiment Construction
[0023] The schematic diagram illustrates the swivel area 1 of the slat chain 2 . Therein, the flight link chain 2 comprises individual flight links 3 guided in parallel in an interacting relationship with one another in their connection areas via connection elements 6, 7, forming flight flight elements 3'. The connecting elements 6 , 7 are formed by pins 8 , 9 and guide bushes 10 , 11 . Between the connecting regions 4 , 5 of the individual parallel chain plates 3 , at approximately half-height, guide rollers 12 are arranged, rotatable about axes 13 . If possible, without generating polygonal and turning effects, the link chain 2 turns around a sprocket 21 arranged therein, for example, in the turning region 1 of an escalator or a moving walk (not shown further). The sprocket 21 is provided with a circular seat 14 for receiving the guide roller 12 . Between the circular seats 14 , an engagement zone 15 is provided for receiving and guiding the connection elements 6 , 7 ie bu...
