DUPLEX GUIDE RAIL MECHANISM

摘要

PPROBLEM TO BE SOLVED: To provide a duplex guide rail mechanism operated smoothly and quietly. PSOLUTION: In the duplex guide rail, a main body projection part 10T is provided on the front part of a main body side rail 10, an association roller 20N is freely rotatably attached at a position of an intermediate rail corresponding to a position P2' on the front side by a prescribed amount from a rear end position P1' of the main body projection part in the pull-out completion state of the intermediate rail 12 to the main body side rail, and a pull-out body projection part 14T is provided over a prescribed range on the rear side from a position P1 of a pull-out body side rail corresponding to a position of the association roller in the state where the retreat of the pull-out body side rail 14 to the intermediate rail is completed. In the duplex guide rail, connection mechanisms 30 and 14H are provided such that the intermediate rail and the pull-out body side rail are moved together in the process of pulling out a pull-out body from a housing completed state and having the association roller reach the main body projection part and the process of completing housing after the association roller separates from the main body projection part and they are separated at the other time.
