Patent ID: 7849633

Claim:
A guide apparatus for guiding a movement of a plurality of doors with respect to a main body between a set position and a preparation position that is in front of or behind said set position and between said preparation position and a non-set position positioned at a side of said preparation position, wherein said plurality of doors are flush with each other in said set position and when arranged side by side, said guide apparatus comprising: a roller mounted on at least one of upper and lower edge portions of each of said plurality of doors; and a plurality of rotatable rails having a length approximately equal to a width of said plurality of doors and arranged in a line extending horizontally in a left and right direction, wherein each of said plurality of rotatable rails is supported by said main body such that said plurality of rotatable rails rotate between a first rotation position and a second rotation position about a first rotation axis extending horizontally in the left and right direction, wherein each of said plurality of rotatable rails includes a supporting surface, an auxiliary track, and an additional track, wherein in said first rotation position, each of said plurality of rotatable rails supports a corresponding one of said plurality of doors in said set position by making said roller ride on said supporting surface, wherein in said second rotation position, each of said plurality of rotatable rails supports a corresponding one of said plurality of doors in said preparation position by making said roller ride on said auxiliary track, and wherein when one of two adjacent ones of said plurality of rotatable rails is in said second rotation position, a surface of said auxiliary track of said one of two adjacent ones of said plurality of rotatable rails is coplanar to a surface of said additional track of the other of said two adjacent ones of said plurality of rotatable rails in said first rotation position.
