In the present invention, disclosed is an interlocking device of sliding window and door which can apply existing parts such as a window and door fixing member, a rotating member, and the like to slim type sliding window and door which have lateral plates with narrow widths. The interlocking device of triple-interlocked sliding window and door comprises a middle guiding rail which is arranged on the upper side of a middle window and door part; a first guiding rail which is arranged on the upper side of a first window and door part arranged on the left side of the middle window and door part; a second guiding rail which is arranged on the upper side of a second window and door part arranged on the right side of the middle window and door part; a pair of rotating members which is arranged on both sides of the middle guiding rail; a rotary belt which is in contact with the outer circumference of the rotating members and rotates by external force; and a pair of window and door fixing members which is installed by being connected with the rotary belt and slides. The lengths of the middle guiding rail and the second guiding rail are longer than the length of each of installed window and door parts. The left end parts of the guiding rails protrude from each of the installed window and door parts. According to the present invention, production cost can be reduced by using parts of the existing window and door interlocking device. A slim type sliding window and door can be used, thereby improving openness and ensuring wide view of field. |
