A handrail type automatic sliding door is provided to solve the trouble of installing a frame equipped with a guide rail to the upper part of the whole section where a sliding door moves and to cut down expenses, and to expand a space for installing an emergency door between entrances to evacuate from a train in an emergency by minimizing equipment installed in a housing space of a sliding door in case of using as a screen door in a platform. A handrail type automatic sliding door comprises a fixed frame portion(100) composed of a space portion(110) between a front frame(101) and a rear frame(102), and first guide rail coupling bodies(120a,120b) attached horizontally to the upper and lower parts of the backside of the front frame and provided with first support members(130a,130b) fixed to the fixed frame portion, first rack gears fixed to the first support members and first guide members(150a,150b) fixed to the top of the first support members and the first rack gears to make guide grooves(152) face upward, a sliding door portion(200) composed of a sliding door(210), second guide rail coupling bodies(220a,220b) attached to the top and bottom of the front of the sliding door to be opposite to the first guide rail coupling bodies at a certain distance and a safety pad(270) attached to an end in the opening direction of the sliding door, and a movable driving portion(300) engaged with the first guide rail coupling bodies and the second guide rail coupling bodies, moved along the first guide rail coupling bodies and the second guide rail coupling bodies by clockwise and counterclockwise rotations of a driving motor to operate together with the sliding door portion to open and close an entrance and composed of a bar shaped pinion shaft, pinion gears installed to the upper and lower parts of the pinion shaft and rotated together with the pinion shaft, plate shaped connecting brackets(320a,320b) installed to penetrate the upper and lower parts of the pinion shaft from the upper part of each pinion gear, guide blocks(330a,330b) fixed to the bottom of each connecting bracket and coupled to the first guide rail coupling bodies and the second guide rail coupling bodies and a driving motor(310) fixed to the top of the connecting bracket installed to the upper part of the pinion shaft and coupled with the top of the pinion shaft to rotate the pinion shaft. |
