AUTOMATIC CLOSING TYPE SLIDING DOOR

摘要

PROBLEM TO BE SOLVED: To make the stop function of an intermediate stop device unavailable as required, and to open and hold a door body or automatically close and return an automatic closing type sliding door in the sliding door with the intermediate stop device. SOLUTION: A door body 2 is stopped and held at an arbitrary open place by frictional working among the three of a friction roller 21, a friction body 23 and a rolling surface 22. A shaft 24 for the friction roller 21 is floated and separated and operated from the rolling surface 11 by a changeover device T, and the display of a stop function of the friction roller 21 is obstructed when the door body 2 is opened and closed. The changeover device T is changed over and operated at the position of operation and the position of a standby by an operating body 40 by a hand.
