Description

Moving body for sliding windows and doors horizontally and window system having the same}

The present invention relates to a sliding window and door horizontal contact moving body and a window system having the same. Because it moves horizontally, it relates to a movable body for horizontal adhesion of sliding windows, which is excellent in airtightness, watertightness and wind pressure resistance of sliding windows, and a window system having the same.

Windows and doors are largely classified into casement windows and sliding doors according to the opening and closing method. The casement window refers to a window that is opened and closed while a window coupled to a window frame through a hinge rotates with the hinge as a rotation axis. Casement windows have excellent airtightness, watertightness, and wind pressure resistance, and have the advantages of easy partitioning and structural assurance of windows and doors. However, in case of casement windows, the elevation of the windows viewed from the inside is not as beautiful as that of Miseogi windows, and if there is no special fixing device, the window suddenly opens or closes by the wind and occupies the interior space.

Sliding windows refer to windows that open and close while a window combined with a rail provided in the window frame performs a linear reciprocating motion along the rail. Miseogi windows have the advantage of having a beautiful elevation compared to casement windows, but also have disadvantages in that airtightness, watertightness and wind pressure resistance are not good compared to casement windows.
